INT CL 3 B 25 B 27/02 Index at acceptance B 4 C 26 B A 4 A El E 7 ( 54) A UNIT FOR ACCOMMODATING DISPOSABLE BLADELIKE ARTICLES ( 71) We, RICHARD-ALLEN MEDICAL INDUSTRIES, INC, a corporation of the State of Illinois, U S A of 8850 M-89, Richland, Michigan 49083, U S A do hereby declare the invention for which we pray that a Patent may be granted to us and the method by which it is to be performed to be particularly described in and by the following statement:-
This invention relates to a disposable unit for the removal and permanent accommodation of used blades.
In present surgical procedure, each scalpel or the like normally includes a reusable handle having a boss on which is mounted a replaceable blade The handle per se is normally subjected to repeated sterilization and thus is reusable; whereas, the blade is used once and then disposed of.
Each blade is provided with a suitable slot formed therein which is adapted to slidably accommodate and interlock with the handle boss The size and shape of the cutting edge of the blade may vary over a wide range and will depend upon the type of surgery to be performed The interconnection between the blade and boss is such that the slotted blade portion must be distorted slightly relative to the boss when the blade is being assembled on or disassembled from the boss.
After use, the blade is soiled and becomes difficult, awkward and hazardous for the nurse or attendant to manually remove same from the boss Furthermore, at the conclusion of the surgery it is imperative that all used and unused blades be accounted for Thus, to meet such requirements,’ a systematic expeditious and reliable procedure must be followed.
In addition to blades, numerous items such as disposable needles of preselected sizes and shapes are utilized and must be strictly accounted for during and at the conclusion of the surgery To facilitate an accurate count, it is desirable to keep the used needles in an exposed yet safe location within a given area and separated from one another.
Also, during the course of the surgery, a substantial amount of sundry articles or trash is generated by opened sterile packages, enclosures, wrappings and the like As in the case of the used blades and needles, it is important that such 55 trash be accounted for and contained in an orderly maner for disposal.
Various devices and systems have hereto been proposed in an effort to meet the stringent requirements for accounting and 60 disposal of the various used blades, needles and sundry articles Such prior devices and systems, however, have been beset with one or more of the following shortcomings: (a) the device was of complex, 65 bulky construction; (b) the device was awkward and frustrating to manipulate; (c) the device was not readily disposable and did not effectively retain the used articles in such a way that they could be readily 70 accounted for without physically touching the article; (d) the device was incapable of accommodating a variety of soiled articles, and (e) the device was incapable of automatically removing a blade or like 75 article from the boss of a handle and then entrapping the removed blade in a convenient, yet safe, manner within a compartment.
According to the present invention there 80 is provided a disposable unit for the removal and permanent accommodation of used elongate bladelike articles supported in use lengthwise on a boss of an elongate manipulating handle, the bladelike articles 85 having a distortable trailing end portion and being removed endwise from the handle by the disposable unit without physical contact between the used article and the person utilizing the unit, the unit 90 comprising a receptacle provided with at least one interior elongated article-accommodating compartment accessible only through an entry formed in at least one end of the compartment, said entry having 95 a configuration for permitting the boss and assembled article to be manually inserted endwise into the compartment through the entry and only the boss to be manually withdrawn endwise from the 100 PATENT SPECIFICATION
1 593 599 1 593 599 compartment through the entry subsequent to the article being removed therefrom, the entry including a first perimetric segment and a second perimetric segment in spaced relation with respect thereto; protruding cam means disposed within the compartment in the path of movement of the boss and assembled article and adjacent the second perimetric segment for engaging and distorting the trailing end portion of the article independently of the boss when the boss and assembled article are manually inserted endwise through the entry into the compartment, the distorted article trailing end portion abutting a fixed portion of a first compartment-forming wall and being automatically removed substantially endwise from the boss and permanently entrapped within the compartment when the boss is withdrawn from the compartment through the entry, the fixed portion of the compartment-forming wall being adjacent to but offset from the cam means and coacting therewith to effect blockage of the entry with respect to the removed article accommodated within the compartment.
The invention will now be described by way of example with reference to the accompanying drawings in which:
Fig 1 is a fragmentary perspective view, partially in vertical section, of one form of the unit and showing the receptacle and traylike member thereof in nested relation and disposed within an outer protective wrapping, the latter being shown in phantom lines; Fig 2 is an end view of the receptacle and traylike member of Fig 1 disposed in disassembled relation and showing, in dotted lines, trash contained within the traylike member; Fig 3 is an end view of the components of Fig 2 shown assembled in inverted relation ready for disposal; Fig 4 is an enlarged fragmentary plan view of a corner portion of the receptacle taken along line 4-4 of Fig 2 and showing only one compartment formed therein; Fig 5 is a left end elevational view of the portion of the receptacle of Fig 4 and showing the entry formed in the end wall thereof; Fig 6 is a sectional view taken along line 6-6 of Fig 4; Fig 7 is a fragmentary sectional view taken along line 7-7 of Fig 4; Figs 8 A-8 C are similar to Fig 7 but showing respectively the boss and attached blade partially inserted into the compartment; fully inserted into the compartment; and with the blade being automatically disassembled from the boss, as the latter is being manually withdrawn from the compartment through the entry; Fig 8 C also shows in section a plurality of used needles attached to the exterior of the receptacle; Fig 9 is a top plan view of the traylike member of Fig 2; 70 Fig 10 is a side elevational view of the trayiike member of Fig 9; Fig 11 is an enlarged fragmentary sectional view taken along line 11-11 of Fig.
9; 75 Fig 12 is a fragmentary bottom view of a second form of receptacle with the bottom panel thereof removed so as to expose the cam means protruding downwardly from the top panel into the compartment; 80 Fig 13 is a fragmentary sectional view taken along line 13-13 of Fig 12; Fig 14 is a fragmentary sectional view, similar to Fig 8 A, of a third form of receptacle and showing the relative disposi 85 tion of the boss and attached blade with respect to the cam means as the boss and blade are being inserted into the compartment through the entry thereto; Fig 15 is similar to Fig 14 but showing 90 a fourth form of receptacle; Fig 16 is similar to Fig 14 but showing a fifth form of receptacle; and Fig 17 is the same as Fig 16 but showing the relative position of the boss and 95 attached blade with respect to the cam means just prior to the boss being withdrawn from the compartment.
Referring now to the drawings and more particularly to Fig 1, one form of the 100 improved unit 20 is shown which includes a receptacle 21, a traylike member 22 in which the receptacle is initially nested, and an outer protective wrapping 23 (e g, a peel-away sheath; a vacuum formed blister 105 type membrane; or the like) The receptacle and member in a compact nested relation are assembled within the protective wrapping and then the components 21, 22 are subjected to sterilization 110 Prior to the commencement of surgery, the nested receptacle and member are removed from the protective wrapping, placed within the sterilized zone or area wherein the surgery is to be performed, and then 115 the receptacle 21 and member 22 are separated from one another and placed in convenient locations (see Fig 2) within the zone.
At the conclusion of the surgery and, 120 after the various used blades B, needles N (see Fig 80), and trash t have been collected within andlor attached to the receptacle and traylike member and accurately accounted for, the receptacle and 125 traylike member are reassembled in inverted relation, as seen in Fig 3, and then appropriately disposed of in accordance prevailing sanitary rules and regulations.
Receptacle 21 may take various forms 130 1 593599 and shapes and will depend in part upon the number, style and type of blades likely to be used in the course of performing the surgery The receptacle 21, shown in Fig.
51, is particularly suitable for accommodating eight used blades B in a manner to be hereinafter described The number and arrangement of the compartment C formed in the receptacle may vary from that illustrated without departing from the scope of the invention hereinafter described and claimed Receptacle 21 is preferably formed of a rigid transparent thermoplastic material and includes a bottom panel 24, an upright wall 25 delimiting same, and a top panel 26 The outer perimeter of top panel 26 is delimited by an upright flange a (see Figs 2 and 6).
The receptacle 21, as seen in Fig 1 is provided with eight interior blade-accommodating compartments, which are arranged in two parallel rows I and II of four compartments each Thus, corresponding compartments of each row are disposed in end-to-end relation and are separated by a common partition 27 (see Fig 7).
Adjacent compartments in a row are separated from one another by a common partition 28 (see Fig 6) Partitions 27, 28 may be integral with either the top or bottom panel and extend the full distance between top panel 26 and bottom panel 24.
Upright wall 25 includes parallel opposed side sectons 25 S and parallel opposed end sections 25 e The aforenoted flange 25 a formed on the upper portion of wall 25, is offset outwardly a slight amount so as to form a shoulder 25 b (see Fig 2).
The end sections 25 e of wall 25 are each provided with four entries E aligned with corresponding compartments formed within the receptacle Each entry E is of like configuration and includes a lower perimetric segment 30 formed in the end wall section 25 e, and an upper segment 31 which is defined by an edge of top panel 26 (see Figs 4 and 5) Flange 25 a is prefereably continuous and encircles the top panel 26 for reasons to be hereinafter explained.
As seen in Fig 4, segment 31 comprises the distal end of a resilient tonguelike element 26 a formed in the top panel 26.
A pair of tortuous slots S separate the sides of the element from the remainder of the panel 26 The tortuous configuration of the slots S forms nodes u on the sides of the slots and thus prevents the entrapped blade from accidently sliding out through one of the slots once it has been disposed within the compartment C.
Affixed to the underside of element 26 a and depending therefrom is a cam means 32 The cam means includes a pair of laterally spaced protuberances 33, each of which has a surface 33 a thereof, adjacent the entry E, tapered downwardly and away from the entry (see Fig 7) The configuration of the entry is such that it will 70 accommodate the boss T of the handle H and the blade B attached thereto when the boss and blade are inserted through the entry into the compartment C (see Fig.
8 A), as will be described more fully here 75 inafter.
The spacing X between the protuberances 33 of the cam means 32 (see Fig 6) is such that only the boss T of the handle H will pass therethrough as the boss is 80 inmerted Pinto or with drawn from the compartment C.
As seen in Fig 7, there may be disposed inwardly of wall end section 25 e, an upright panel 34 which extends between 85 the bottom panel 24 and underside of top panel 26 Panel 34 is substantially parallel to end section 25 c and is provided with an opening 34 a which is aligned with but slightly larger than the interruption formed 90 in the wall end section A portion 34 b of opening 34 a is recessed a slight amount and is beveled downwardly (see Fig 7).
The perimetric segment 30 of the interruption formed in wall end section 25 e 95 is also provided with a recessed portion a which is beveled downwardly in substantially the same manner as portion 34 b of panel 34.
It will be noted in Fig 7 that the 100 beveled surfaces 30 a and 34 b are disposed in substantially the same inclined plane.
The beveled recessed portions of end section 25 e and panel 34 are adapted to accommodate the portion Ta of the boss T 105 which extends beneath the attached blade B (see Figs 8 A and 8 C) when the boss is passing through the entry E.
As seen in Fig 8 A, when the boss T and attached blade B are initially inserted 110 through the entry, the blade B and boss portion Ta are manipulated so as to pass beneath the cam means protuberances.
Because the underside of the blade slidably engages the portions of perimetric seg 115 ment 30 disposed on opposite sides of the recess 30 a, the blade upperside will engage the ends of the protuberances and cause the tonguelike element 26 a to be resiliently deflected upwardly a slight amount Once 120 the boss and attached blade have been inserted into the compartmrent a sufficient amount so that the trailing end Ba of the blade passes inwardly of panel 34, the trailing end of the blade will be deflected 125 downwardly relative to the boss underside by the force of the tonguelike element 26 a so that the trailing edge of the blade will be below the portions 34 c of the opening 34 a disposed on opposite sides 130 1 593 599 of the recess 34 b (see Figs 5 and 8 B).
Once the trailing edge Ba of the blade B has assumed the deflected position, the trailing edge will abut the inside surface of panel 34 as the boss T is being withdrawn from the compartment Because of the deflected condition of the trailing end of the blade, the boss portion Ta will slide endwise out of the slot formed in the blade itself and effect disassembly of the blade and boss The disassembled blade will remain within the compartment after the boss has been withdrawn from the receptacle The slotted blade and the boss are of conventional designs and per se form no part of the claimed invention.
Because of the depending cam protuberances and the tortuous configuration of the, slots S, the entrapped blade will remain inaccessible within the compartment notwithstanding that the receptacle is subjected to abusive handling The preferred practice with receptacle 21 is to entrap only one used blade in each compartment thereby facilitating accounting of the used blades during and at the conclusion of the surgery The top panel 26 is preferably formed of transparent material thereby enabling the entrapped blade to be readily observed.
It is important to note the receptacle 21 embodies various structural features which enable the used blade to be readily disassembled from the boss while the blade is completely disposed within the compartment This feature effectively removes the hazards normally associated with blade removal in that no physical contact between the blade and the fingers of the person utilizing the receptacle is required.
Figs 12, 13 illustrate a modified form of receptacle 121 which differs from receptacle 21 only with respect to the cam means 132 wherein a single protuberance 133 is disposed adjacent the entry E and depends from the top panel 126 A second depending protuberance 133 ‘ is also provided which is spaced inwardly from protuberance 133 and is disposed slightly askew (see Fig 12) Protuberance 133 resiliently engages a portion of the attached blade disposed to one side of the tang and causes the trailing end portion of the blade to be deflected downwardly relative to the boss a sufficient amount so that the trailing end portion will abut the inner panel 134 when the boss is withdrawn The second protuberance 133 ‘ serves to guide the leading end portion of the inserted blade, so that the boss will be in proper alignment with entry E for withdrawal The arrangement of the protuberances 133 and 133 ‘ have been found to be particularly suitable for relatively narrow blades.
Fig 14 discloses a modified receptacle 221 which embodies numerous structural features incorporated in receptacle 21.
Accordingly, like features in receptacle 221 are identified by the same numerals 70 as receptacle 21 except in the two hundred series The principal difference between receptacles 21 and 221 is that in receptacle 221, the tongue-like element 226 a, to which the cam protuberances 233 a ex 75 tend, is formed so as to have a normal upwardly bowed configuration with respect to the top panel 226 whereby the protuberances do not extend into the compartment C until manually depressed A button 80 Y may be provided on the exterior of element 226 a to facilitate depressing thereof when desired The element 226 a is depressed only, after the boss and attached blade have been inserted into the compart 85 ment a sufficient amount so that the trailing end Ba of the blade has cleared the end wall of the receptacle in which the entry E is formed The element 226 a remains manually depressed while the boss 90 is withdrawn endwise from the compartment and the detached blade remains entrapped within the compartment.
Fig 15 illustrates a modified receptacle 321 which is similar to receptacle 221, 95 except that element 326 a is connected to the top panel 326 by a hinge h The hinge is spring-biased so that segment 326 a normally assumes a raised position (see Fig.
15) wherein the cam protuberances 333 a 100 formed on the element do not extend into the compartment C.
Figs 16-17 illustrate another modified receptacle 421, wherein in lieu of a tonguelike element, the cam protuberances 433 a 105 extend downwardly from the top panel 426 and assume a stationary position at all times The protuberances 433 a are spaced inwardly a substantial amount from the end wall of the receptacle in which 110 the entry E is formed The depth of the compartment formed in receptacle 421 is greater than in the previously described receptacles, so that the boss and attached blade may be initially inserted through 115 the entry into the compartment and beneath protuberances 433 a a sufficient amount so that the trailing end portion Ba of the attached blade will clear the end wall of the compartment and be 120 aligned beneath the protuberances 433 a.
To effect such positioning of the attached blade it is necessary that the boss and attached blade be inserted at an inclined angle AA (see Fig 16) Once the boss 125 and blade have been inserted into the compartment the required amount, the handle H is manually pivoted in a counterclockwise direction about a perimetric segment 430 of the entry as a fulcrum to 130 1 593 599 a substantially horizontal position whereupon the depending stationary protuberances 433 a will cause the trailing edge Ba of the blade to be distorted downwardly, as shown in Fig 17 While the handle remains in a substantially horizontal position, the boss thereof is withdrawn from the compartment causing the distorted trailing end of the blade to abut the end wall of the compartment and the blade to be removed endwise of the withdrawing boss.
It should be noted, for purposes of clarity, that receptacles 221, 321 and 421 do not show double panels at the entry nor periphery flanges delimiting the top panels or various other structural features embodied in receptacle 21; however, such features may be included if desired Furthermore, receptacles 221, 321, 421 may be provided with a plurality of compartments rather than the single compartment as shown.
It will be noted in Fig 1 that the exposed surface of the top panel 26 of the receptacle 21 is provided with a plurality of strips 35 a, b, and c which are of magnetic material Each strip is affixed to the exposed surface by suitable means and is provided with a plurality of longitudinally spaced peripheral notches which are adapted to receive lugs 36 formed on the surface The lugs retain the strips in proper spaced parallel relation It is preferred that the strips 35 a-b be aligned with the partitions 28 (see Figs 4, 6) which separate the adjacent compartments of a row I or II Similar magnetic strips may be utilized with receptacles 121, 221, 321 and 421.
The strips serve to hold needles N and similar ferrous metal articles in selected, separate positions on the exposed surface of the top panel One such needle is shown in phantom lines in Fig 1 Because the needles may vary in length and shape, the number of strips contacted by a given needle may vary from that shown The peripheral flange 25 a, which delimits the s O top panel 26, provides protection against the ends of the needle accidentally piercing a person or their wearing apparel.
Figs 9-10 reveal the structural details embodied in one form of the traylike member 22, shown in Figs 1 and 2 Member 22 is preferably of one piece construction and formed from an inexpensive, disposable plastic material Member 22 includes a bottom section 22 a which closely approximates the configuration of the bottom panel 24 of the receptacle 21 The inner surface of bottom section 22 a is provided with a coating 37 of suitable tacky, non-drying material (e g a synthetic resin emulsion, pressure-sensitive adhesive-Swift #46363) It will be noted in Fig 1 that, when receptacle 21 and the traylike member 22 are in nested relation, the bottom section 22 a and the coating 37 thereon are spaced from the underside of 70 the receptacle bottom panel 24.
Delimiting the bottom section 22 a and extending upwardly therefrom is a continuous wall 22 b which includes side and end sections corresponding closely to those of 75 the receptacle The height of the wall 22 b is greater than the height of the receptacle wall and, thus, assures a spacing of the receptacle bottom panel from the coating 37 when the components are in nested re 80 lation (see Fig 1) The upper portion of the wall 22 b is offset outwardly so as to form an interior ledge 22 c (see Fig 11).
The ledge is adapted to supportingly engage the exterior shoulder 25 b formed in the 85 wall of the receptacle (see Fig 2) when the receptacle is nested within the member 22 The ledge 22 c also limits the extent to which the receptacle 21 and member 22 can be pushed together when they are 90 in inverted relation As a further means of maintaining the bottom panel of the receptacle in proper spaced relation with coated bottom section of the traylike member when the latter and the receptacle are 95 in nested relation, an upwardly projecting spacer rib, not shown, may be provided on the inner surface of the bottom section of the member 22 Such a rib would engage the underside of the receptacle and pre 100 vent jamming together of the receptacle and member A plurality of finger cutouts or slots F may be formed in the offset upper portion of the wall 22 b so as to facilitate denesting of the receptacle and 105 traylike member.
In addition to the ledge 22 c, the interior surface of the upper portion of the wall 22 b is provided with a plurality of spaced inwardly projecting nubs 22 d The nubs 110 are adapted to lock into suitable recesses, not shown, formed in the exterior surface of the peripheral flange 25 a which surrounds the top panel 26 of the receptacle, only when the latter and the traylike mem 115 ber 22 are in inverted relation (see Fig 3).
When the components 21 and 22 are separated from one another, as seen in Fig.
2, the member 22 is adapted to collect on the coated surface thereof, various 120 articles of trash which are normally generated in the course of the surgery (e g, discarded wrapers for sterilized articles, such as blades or the like) Because of the tacky character of the coating 37, the 125 articles of trash will remain adhered to the bottom section of the traylike member 22, notwithstanding that the latter may assume an inverted position with respect to the receptacle The inverted positioning 130 1 593 599 of the receptacle and traylike member normally occurs at the conclusion of the surgery and after the blades, needles and articles of trash have been accounted for.
The assembled inverted components may then be suitably disposed of in accordance with the rules of the hospital, clinic or the like governing the disposal of such articles.
The traylike member 22 may be used in the same manner as described with respect to modified receptacles 121, 221, 321 and 421.
While the receptacles 21, 121, 221, 321 and 421 have been described for use in disposing of surgical blades, it is to be understood that it is not intended to be so limited For example, such receptacles may be used to remove wood-carving blades or the like from bosses In this latter instance, sterilization of the unit is not required Furthermore, the movement of the boss and attached blade to effect distortion of the blade from the boss has heretofore been described as pivoting and horizontal; however, in certain instances it might require a twisting movement followed by a horizontal movement This latter sequence of manipulations will depend upon the arrangement and configuration of the cam protuberances and the manner in which the blade is attached to the boss.
As previously mentioned, the size and shape of the various unit components may vary over a wide range and will depend upon the circumstances surrounding the surgery to be performed In certain instances, where there is only one row of compartments formed in the receptacle, each compartment might be provided with an entry at each end The unit 20 under any circumstances eliminates the serious hazards associated with manually removing a used blade from a conventional scalpel handle Furthermore, the unit enables a quick, accurate and reliable accounting of the various articles used during surgery to be made, thereby greatly facilitating the surgery procedures The components of the unit are compact, inexpensive to produce, and may be readily disposed of when required.
