  An embodiment for carrying out the present invention will be described with reference to FIGS. This is merely an example, and the technical scope of the present invention is not limited to this.

  1 to 4, “upward” refers to the direction of arrow X1 in FIG. 1, and “downward” refers to the direction of arrow X2. Further, an upper side from a certain position is referred to as “upper side”, and a lower side from a certain position is referred to as “lower side”.

  As shown in FIG. 1, the waste needle recovery container 10 is used for recovering the injection needle portion 96 screwed onto the distal end 92 of the syringe main body 90 shown in FIG. The waste needle collection container 10 includes a container body 12 and an opening 14. Further, the waste needle collection container 10 includes a lid 114 that covers the opening 14.

  The container main body 12 has a column-shaped side portion 16, a bottom portion 18 that covers the lower portion of the side portion 16, and a cylindrical mouth portion 20 (see FIG. 9) formed in the upper portion 16 a of the side portion 16. The surface is a substantially U-shaped container. The side portion 16 has a cylindrical side surface shape, but may have other shapes, for example, a quadrangular prism side surface shape, an octagonal side surface shape, an elliptical cylinder side surface shape, etc., or a truncated cone shape or a truncated pyramid shape. There may be.

  The bottom portion 18 includes, for example, a substantially disk-shaped bottom. The bottom portion 18 may further include a non-slip portion 22 disposed below the bottom. The anti-slip part 22 is formed of a material that makes it difficult for the installation surface F such as the upper surface of the desk and the anti-slip part 22 to move relative to each other, for example, an elastic body such as rubber. . The anti-skid part 22 has an effect of preventing the anti-skid part 22 and the installation surface F from sliding with each other by a rotational force that rotates around the columnar central axis C of the side part 16.

  The side portion 16 is separated from the syringe main body 90 and has a size that can accommodate a plurality of collected needle portions 96. The side portion 16 further includes a disposal port portion 24 for discarding the plurality of injection needle portions 96 accommodated therein, and an opening / closing member 26 such as a cap for opening and closing the disposal port portion 24.

  The disposal port portion 24 is formed in a cylindrical shape having a central axis extending in a direction parallel to the central axis C of the side portion 16, but is not limited thereto, and is formed in a cylindrical shape having a central axis extending in an arbitrary direction. It may be formed.

  As shown in FIG. 2, the discard port portion 24 has, for example, a cylindrical shape, and a disc-shaped flange portion 24 a is formed at the upper end portion of the discard port portion 24. Accordingly, the groove 24b is formed by the flange 24a and the upper portion 16a.

  As shown in FIGS. 3 and 4, the opening / closing member 26 includes, for example, a disk-shaped base portion 26 a having a size capable of covering the disposal port portion 24, and a base portion extending from one surface of the base portion 26 a. 26a includes a flange portion 26b extending toward the center of 26a, a plate-like hinge portion 26f extending from the base portion 26a, and a disk portion 26e formed on the hinge portion 26f. The opening / closing member 26 is preferably formed of the same material as the container body 12, for example.

  The flange portion 26b and the base portion 26a form a groove portion 26c. A hole 26d having a diameter slightly larger than the diameter of the valley of the groove 24b is formed in the disk portion 26e (see FIG. 2). The diameter of the trough of the groove 26c is substantially the same as the diameter of the tip of the flange 24a.

  As shown in FIG. 2, the hole 26 d of the disk part 26 e is fitted in the groove part 24 b of the disposal port part 24. The opening / closing member 26 closes the disposal port portion 24 by fitting the groove portion 26c to the flange portion 24a in a state where the hinge portion 26f is bent. Therefore, the opening / closing member 26 is elastically deformed between the opening / closing member 26 and the disposal port portion 24 by pulling the opening / closing member 26 upward or fitting the flange portion 24a to the groove portion 26c when necessary. Then, the disposal port 24 is opened or closed.

  As shown in FIG. 5, for example, a hook for removing the injection needle portion 99 fitted to the syringe main body 98 of the syringe for insulin shown in FIG. 8 from the syringe main body 98 with one hand is disposed inside the disposal port portion 24. The part 25 may be formed. For example, the hook portion 25 is preferably formed of the same material as the disposal port portion 24. The hook portion 25 includes, for example, a base portion 25a that extends inward from about half of the inner peripheral surface of the disposal port portion 24, and an extension that extends from both ends of the base portion 25a to the center of the disposal port portion 24. The existing portion 25c is provided with a slit forming portion 25d that forms a cross-shaped slit 25b near the center of the disposal port portion 24 at the end of the extending portion 25c.

  As shown in FIG. 8, the insulin syringe includes a syringe main body 98 and an injection needle portion 99 fitted to the tip 98 a of the syringe main body 98. The injection needle portion 99 includes a cylindrical portion 99b that fits the distal end 98a of the syringe main body 98, and a flange portion 99a that is formed at an end portion of the cylindrical portion 99b. The outer diameter of the cylindrical portion 99b is preferably slightly smaller than the width of the slit 25b. The outer diameter of the flange 99a is preferably slightly larger than the width of the slit 25b.

  As shown in FIG. 9, the mouth portion 20 is formed in a cylindrical shape in the upper portion 16 a so as to coincide with the columnar central axis C of the side portion 16. A male screw 28 is formed on the cylindrical outer peripheral surface of the mouth portion 20. The rotation axis of the male screw 28 substantially coincides with the cylindrical center axis C of the side portion 16.

  As shown in FIG. 1, the side part 16, the upper part 16 a, the bottom part 18, and the mouth part 20 of the container body 12 are all formed of a resin material such as plastic, in particular, a visible resin material. However, it may be formed of a metal material such as stainless steel or steel.

  As shown in FIGS. 1 and 6, the opening 14 is located on the upper surface of the container body 12. The opening portion 14 has a separation portion 32 in which a female screw 30 that is screwed into the male screw 28 of the mouth portion 20 of the container body 12 is formed. The separation part 32 has a cylindrical shape and has a recess that opens downward. A female screw 30 is formed on the inner peripheral surface of the recess so that the central axis of the female screw 30 coincides with the cylindrical central axis C of the side portion 16. A cylindrical convex portion 32a is formed on the upper surface of the separation portion 32, and a lower end of a compression coil spring 54 described later is disposed. The compression coil spring 54 is an example, and is not limited to this as long as it is a biasing means.

  The separation portion 32 is formed with a cylindrical through-hole 34 that penetrates the bottom 33 of the recess and the protrusion 32 a on the upper surface of the separation portion 32. The central axis of the through hole 34 coincides with the cylindrical central axis C of the side portion 16. Accordingly, when the separating portion 32 is rotated with respect to the container body 12 so as to rotate around the central axis C, the male screw 28 and the female screw 30 can be unscrewed. As a result, the opening part 14 has a structure separated from the container main body 12.

  For example, a bearing 50 that is screwed into the ball spline shaft 48 is assembled to the bottom 33 of the separation unit 32 by a known mounting means such as a bolt. The bearing 50 is attached to the bottom 33 of the separation portion 32 so that the axis of the ball spline shaft 48 coincides with the central axis C, for example. The ball spline shaft 48 and the bearing 50 are given as an example of a mechanism for converting a rotational motion into a linear motion, and may be, for example, a trapezoidal screw, a general male screw, or a female screw. Moreover, although the material is demonstrated as a metal, if it can exhibit the function which converts a rotational motion into a linear motion, it will not be limited, For example, resin may be sufficient.

  When the ball spline shaft 48 rotates around the axis of the ball spline shaft 48, the ball spline shaft 48 moves while rotating in the direction in which the axis of the ball spline shaft 48 extends with respect to the bearing 50. In other words, the ball spline shaft 48 and the bearing 50 have a structure that must be rotated around the axis of the ball spline shaft 48 in order for the ball spline shaft 48 to move in the direction in which the axis of the ball spline shaft 48 extends. Have. Therefore, the ball spline shaft 48 and the bearing 50 act as a motion conversion mechanism for rotating the ball spline shaft 48 as the ball spline shaft 48 moves in the direction in which the central axis C extends. Here, since the central axis C passes through the center of gravity of the waste needle collection container 10, the axis of the ball spline shaft 48 passes through the center of gravity of the waste needle collection container 10.

  The ball spline shaft 48 has a through hole 52 that passes through the center of the ball spline shaft 48 in the direction in which the ball spline shaft 48 extends.

  A concave portion 56 is formed in the upper end portion of the ball spline shaft 48. The inner peripheral side surface of the recess 56 has a cylindrical shape.

  The opening 14 includes an inner gripping portion 60 that holds the cylindrical side surface of the holding body 94 and an outer gripping portion 62 into which the inner gripping portion 60 is inserted. The inner gripping part 60 and the outer gripping part 62 act as a gripping means 64 that grips the holding body 94 in cooperation.

  The lower end portion of the outer gripping portion 62 is fitted into the concave portion 56 of the ball spline shaft 48 so as not to be relatively rotatable. The outer gripping portion 62 has a cylindrical shape, and includes a recess 66 that is open on the upper side, and a through hole 68 formed in the bottom of the recess 66. The vicinity of the opening of the recess 66 is formed into a taper that spreads outward, such as a truncated conical side surface. This taper acts as a guide mechanism that guides the lower end of the inner gripper 60 to the recess 66. The center of the inner peripheral surface of the recess 66 and the center of the through hole 68 are both located on the extension line of the central axis C.

  For example, a compression coil spring 70, which is an example of an urging means, is disposed in a compressed state in the recess 66 of the outer gripping portion 62. The compression coil spring 70 preferably has a spring constant smaller than that of the compression coil spring 54. A spacer 72 is slidably disposed on the upper side of the compression coil spring 70. The spacer 72 has a cylindrical shape. In the spacer 72, two long holes 74 that are long in the direction in which the cylindrical axis of the spacer 72 extends are formed on the opposite side surfaces of the spacer 72.

  The inner gripping portion 60 is arranged on the upper side of the spacer 72 so that the lower end portion of the inner gripping portion 60 is in contact with the upper side of the spacer 72.

  An upper spring receiving member 78 is disposed at the upper end of the compression coil spring 70. The upper spring receiving member 78 has a cylindrical shape. A recess 76 is formed at the lower end of the upper spring receiving member 78. The recess 76 has an inner peripheral surface with a diameter slightly larger than the outer diameter of the compression coil spring 54. A recess 80 is also formed on the upper side of the upper spring receiving member 78. The recess 80 holds the bearing 82, for example. In the present embodiment, a bearing is cited, but the present invention is not limited to this, and any configuration that reduces frictional resistance may be used. For example, an oilless bearing or a bush may be used. The upper spring receiving member 78 is formed with a through hole 84 that penetrates the bottom surface of the recess 76 and the bottom surface of the recess 80. The center of the through hole 84 is located on an extension line of the central axis C.

  A cover 86 is disposed at the upper end of the inner gripping portion 60. The cover 86 includes a disk portion 85 and a cylindrical portion 87 formed on the lower side of the disk portion 85. A through hole 88 is formed in the center of the disk portion. The inner diameter of the tubular portion 87 is larger than the outer diameter of the inner gripping portion 60 and the outer gripping portion 62. The outer diameter of the tubular portion 87 is the inner diameter of the compression coil spring 54, the inner diameter of the through hole 84, and the bearing 82. Smaller than any of the inner diameters.

  The inner gripping portion 60 has a through hole 61 penetrating in the vertical direction. The through hole 61 has a diameter slightly larger than the outer diameter of the holding body 94. A slit 63 is formed on the inner side surface of the through hole 61 to act as a clearance when the outer diameter of the inner gripping portion 60 is reduced. On the inner peripheral surface of the through-hole 61, a meshing portion (not shown) is formed that meshes with the unevenness provided on the holding body 94 so that the holding body 94 and the inner gripping portion 60 are not relatively rotatable.

  The inner gripping portion 60 has a structure in which an upper end portion has a cylindrical shape, a central portion has a tapered shape and a lower end portion has a cylindrical shape. The upper end portion has substantially the same diameter as the outer diameter of the outer gripping portion 62. The lower end portion has a diameter that is substantially the same as or slightly smaller than the inner diameter of the outer gripping portion 62.

  A through hole is formed in the cylindrical portion 87 of the cover 86, and a female screw hole is formed in the outer gripping portion 62. A set screw 83 is screwed into the female screw hole through the through hole of the tubular portion 87. Therefore, the ball spline shaft 48 is assembled so as not to move relative to the cover 86 via the outer gripping portion 62 and the set screw 83.

  The compression coil spring 54 is arranged in a state where the compression coil spring 54 is slightly compressed, and its lower end is disposed in the recess 42 of the lower spring receiving member 40 and its upper end is disposed in the recess 76 of the upper spring receiving member 78. Therefore, the upper spring receiving member 78 is urged to always move upward. This biasing force is transmitted to the disk portion 85 of the cover 86 via the upper spring receiving member 78 and the bearing 82.

  The distal end of the set screw 83 protrudes inward from the inner peripheral surface of the recess 66 of the outer gripping portion 62 and is inserted into the long hole 74 of the spacer 72.

  The spacer 72 can slide in the vertical direction by the length of the long hole 74 on the inner peripheral surface of the recess 66 of the outer gripping portion 62. Further, since the compression coil spring 70 is disposed inside the inner peripheral surface of the concave portion 66 of the outer gripping portion 62 in a slightly compressed state, the compression coil spring 70 biases the spacer 72.

  In this way, the holding body 94 is inserted into the opening 14, and the insertion hole 100 through which the holding body 94 separated from the syringe main body 90 described later passes through the through holes 52, 68, 61 and the spacer 72. It is formed by a hole.

  A cover 110 that covers the opening 14 is provided on the upper side of the separation part 32. The cover 110 includes, for example, a cylindrical portion 112 having a cylindrical side surface shape, an opening 116 formed at the upper end of the cylindrical portion 112, and a flange portion 118 that is formed near the opening 116 and extends outward. The diameter of the opening 116 is slightly larger than the outer diameter of the disk portion 85. The cover 110 is preferably formed of, for example, a resin. A hinge support portion 119 is provided on the upper portion of the cover 110, and the hinge support portion 119 is rotatably supported by a hinge portion extending from the outer periphery of the disc-shaped lid portion 114 via a pivot shaft 122. . The lid portion 114 includes a flange portion 120 provided on the opening 116 side. The flange portion 120 extends in the shape of a cylindrical side surface from the vicinity of the outer periphery of the lid portion 114, and extends so as to form a ring on the inner side at the end portion. As shown in FIGS. 1 and 6, the flange portion 120 of the lid portion 114 is normally in a state where it enters the gap between the flange portion 118 of the opening portion 116 and the upper portion of the cover 110, and thereby the opening portion 116 is formed. Sealed.

  As shown in FIG. 1, in the above-described waste needle collection container 10, the upward biasing force is normally applied to the upper spring receiving member 78 and the spacer 72 by the compression coil springs 54 and 70, respectively. Both the ball spline shaft 48 and the inner gripping portion 60 are located on the uppermost side. The lid 114 covers the opening 116.

  The waste needle collection container 10 is used as follows.

  The user administers medicine such as insulin to the body using the syringe body 90. Then, the used syringe body 90 is reliably and easily removed from the syringe body 90 by using the waste needle collection container 10.

  Details will be described below. First, as shown in FIG. 9, the user lifts the lid 114 so as to rotate around the pivot 122 and opens the opening 116. Thereby, the user can visually recognize the through hole 61 of the inner gripping part 60 and can insert the holding body 94 of the syringe main body 90 into the through hole 61 of the inner gripping part 60.

  Next, the user holds the used syringe main body 90 with one hand so that the needle of the syringe main body 90 faces downward, and is positioned above the waste needle collecting container 10. At this time, the central axis of the syringe main body 90 and the central axis of the inner gripper 60, that is, the central axis C are aligned.

  Next, the syringe main body 90 is moved downward, and the outer peripheral surface of the holding body 94 is brought into contact with the inner peripheral surface of the through hole 61 of the inner gripping portion 60. Since the through hole 61 has a diameter slightly larger than the outer diameter of the holding body 94, the holding body 94 can be smoothly inserted into the through hole 61.

  Further, when the syringe main body 90 is moved downward, the lower end portion of the syringe main body 90 comes into contact with the upper end portion of the inner gripping portion 60.

  Further, when the syringe main body 90 is moved downward, the syringe main body 90 and the inner gripping portion 60 are moved downward together. At this time, since the compression coil spring 70 has a spring constant smaller than that of the compression coil spring 54, the compression coil spring 70 yields to the force that moves the syringe main body 90 downward before the compression coil spring 54.

  The lower end portion of the inner gripping portion 60 is inserted into the through hole of the outer gripping portion 62 while pushing the spacer 72 downward and in contact with the taper at the upper end portion of the outer gripping portion 62. Since the tip of the set screw 83 is inserted into the long hole 74, the spacer 72 moves in the longitudinal direction of the long hole 74, that is, in the downward direction.

  When the inner gripping portion 60 is inserted into the through hole of the outer gripping portion 62, the inner gripping portion 60 reduces the inner diameter of the through hole 61 slightly while narrowing the gap of the slit 63. And the holding body 94 are securely gripped so as not to be relatively rotatable.

  In addition, when the inner gripper 60 securely grips the holding body 94 and at the same time the lower end of the inner gripper 60 is inserted into the through hole of the outer gripper 62, the taper of the lower end of the inner gripper 60 is reduced. The inner gripping portion 60 and the outer gripping portion 62 are in a fitted state due to the taper of the upper end portion of the outer gripping portion 62, so that the inner gripping portion 60 and the outer gripping portion 62 are in a relatively non-rotatable state. (This state is called gripping rotation start state).

  Further, when the syringe main body 90 is moved downward, the bias of the compression coil spring 54 is bent and the ball spline shaft 48 is moved downward. When the ball spline shaft 48 moves downward, the ball spline shaft 48 moves downward while rotating due to the screwing of the ball spline shaft 48 and the bearing 50. The rotation of the ball spline shaft 48 is transmitted to the holding body 94 through the outer gripping portion 62 and the inner gripping portion 60, and the other is further transmitted to the cover 86 through the set screw 83.

  At this time, since the user holds the syringe main body 90 firmly by the user, a rotational force acts between the syringe main body 90 and the holding body 94 and the syringe main body 90 actually rotates. That is, when the user lowers the syringe main body 90, a rotational force that unscrews the tip 92 of the syringe main body 90 and the holding body 94 acts. Further, the rotational force that unscrews the distal end 92 of the syringe main body 90 and the holding body 94 also acts on the container main body 12, but hardly rotates due to the non-slip portion 22.

  Further, the vertical movement of the ball spline shaft 48 is performed on an extension line of the central axis C of the container body 12, in other words, in a trajectory passing through the center of gravity of the waste needle collection container 10. That is, the center axis C coincides with the hole direction in which the insertion hole 100 extends, and the holding body 94 performs linear motion in the hole direction.

  Since both ends of the compression coil spring 54 are held by the upper spring receiving member 78 and the lower spring receiving member 40, the upper spring receiving member 78 moves substantially in parallel in the downward direction. Therefore, if a rotational force greater than the anti-slip force of the anti-slip portion 22 acts on the container body 12 and the container body 12 is about to rotate, the user can hold the syringe body 90 with his / her hand. The upper spring receiving member 78 and the container body 12 may be held with the opposite hand.

  The user only has to hold the syringe main body 90 firmly and push it downward while the user's hand is not in contact with the cover 86, and as the ball spline shaft 48 moves, Even if the cover 86 rotates, there is almost no hindrance to the work of pushing down.

  When the syringe main body 90 is further moved downward, the lower side of the upper spring receiving member 78 comes into contact with the upper surface of the lower spring receiving member 40 as shown in FIG. It is impossible to move downward (this state is called gripping rotation end state).

  In this way, the holding body 94 is separated from the distal end 92 of the syringe main body 90 by changing the gripping rotation start state to the gripping rotation end state. The holding body 94 separated from the distal end 92 of the syringe main body 90 freely falls by gravity through the insertion hole 100, that is, the through hole of the spacer 72, the through hole 68 of the inner gripper 60, and the through hole 52 of the ball spline shaft 48. In the state, it passes through and is accommodated in the container body 12 and collected.

  If the holding body 94 is slightly rotated by a single operation from the gripping rotation start state to the gripping rotation end state, but the holding body 94 is not completely separated from the tip 92 of the syringe main body 90, the gripping rotation is performed. In the end state, the user pulls the syringe body 90 upward while pressing the cover 86 downward with the little finger ball of the hand holding the syringe body 90. At this time, since the cover 86 is pressed downward, the outer gripping portion 62 is pressed downward via the set screw 83.

  When the syringe main body 90 is pulled upward in such a state, the inner gripping portion 60 yields to the tensile strength due to the fitting between the outer gripping portion 62 and the inner gripping portion 60, and the inner gripping portion 60 eventually becomes the outer gripping. As a result, the inner diameter of the through hole 61 of the inner gripping portion 60 returns to its original size, and the holding force of the holding body 94 on which the through hole 61 has acted is almost eliminated. The holding body 94 comes off from 61.

  Next, when the user's hand is moved upward, the ball spline shaft 48 is moved upward by the biasing force of the compression coil spring 54, and the original state as shown in FIG. 9 is obtained.

  Then, the user rotates the lid 114 to cover the opening 116. As a result, the holding body 94 accommodated and recovered in the container body 12 is in a state of being substantially isolated from the container body 12 by the sealing of the lid 114, so that it comes into contact with blood or the like attached to the needle of the holding body 94. It is possible to prevent the infection to the user etc. more reliably.

  The user can completely and easily separate the holding body 94 from the distal end 92 of the syringe main body 90 by repeating the above-described operations including the gripping rotation start state to the gripping rotation end state. . In particular, if the user pays attention to the movement of the hand that repeats the above operations including the gripping rotation start state to the gripping rotation end state, the user simply holds the syringe main body 90 in the hand and moves the central axis. Since only the extension line of C is moved up and down, the waste needle collecting container 10 does not require a complicated mechanism or power source as in the conventional case.

  By the way, the container main body 12 of the collection container 10 for waste needles can use a general container. In that case, a waste needle recovery part attached to the general container may be used.

  In such a waste needle collecting part, for example, in FIG. 1 and FIG. 9, a connecting means such as a female screw 30 connected by screwing to a female screw of a general container body and a holding body 94 are inserted. And the opening 14 in which the insertion hole 100 is formed. The opening 14 includes a gripping means 64 that grips the holding body 94 and a motion conversion mechanism that rotates the gripping means 64 in accordance with the linear motion of the gripping means 64 in the direction of the hole in which the insertion hole 100 extends. It is obvious to those skilled in the art that it is necessary.

  Another embodiment will be described with reference to FIGS. 11 and 12.

  11 and 12 is the same as that shown in FIG. 1 except that the spacer 36 and the lower spring receiving member 40 are provided and that the direction of the disposal port 24 is different. From FIG. 6, since it is the same as the collection container 10 for waste needles, it attaches | subjects the same code | symbol and abbreviate | omits description.

  The disposal port portion 24 is formed in a cylindrical shape having a central axis extending in a direction substantially perpendicular to the central axis C of the side portion 16, but is not limited thereto, and is a cylindrical shape having a central axis extending in an arbitrary direction. It may be formed. A male screw is formed on the outer periphery of the disposal port portion 24. The opening / closing member 26 includes, for example, a disk-shaped base, a concave portion formed on one bottom surface of the base, and a grip portion formed on the outer peripheral side surface of the base. For example, a female screw that can be screwed with a male screw on the outer periphery of the disposal port portion 24 is formed on the inner peripheral surface of the recess. Therefore, the opening / closing member 26 can open and close the disposal port portion 24 by rotating the opening / closing member 26 when necessary.

  The opening 14 has, for example, a cylindrical spacer 36 on the upper side of the separation part 32. The spacer 36 has substantially the same diameter as the diameter of the cylindrical outer peripheral surface of the separation part 32. A through hole 38 is formed in the spacer 36 in the direction in which the axis in the circle extends. The through hole 38 is formed such that the central axis of the through hole 38 coincides with the cylindrical central axis C of the side portion 16.

  The opening 14 has a lower spring receiving member 40 above the spacer 36. The lower spring receiving member 40 has a substantially cylindrical shape, and a recess 42 is formed at the upper center thereof. At the center of the bottom portion 44 of the recess 42, a through hole 46 that penetrates the lower surface of the lower spring receiving member 40 so that the central axis of the through hole 46 coincides with the cylindrical central axis C of the side portion 16. Is formed. Therefore, all of the through hole 34, the through hole 38, and the through hole 46 coincide with the columnar center axis C of the side portion 16, and thus form concentric circles. Further, each of the through hole 34, the through hole 38, and the through hole 46 has a diameter that allows the ball spline shaft 48 to be inserted in a non-contact and rotatable manner.

  The lower end of the compression coil spring 54 is disposed in the recess 42 of the lower spring receiving member 40. The compression coil spring 54 preferably has an inner diameter larger than the outer diameter of the ball spline shaft 48 so that the ball spline shaft 48 is positioned inside the compression coil spring 54 and can move up and down rotatably.

  Since the opening 14 has a cylindrical spacer 36 on the upper side of the separation part 32 and a lower spring receiving member 40 on the upper side of the spacer 36, the ball spline is more than the waste needle collection container 10 shown in FIGS. 1 to 6. The stroke of the shaft 48 can be shortened.

  As described above, the user can reliably and repeatedly perform the above-described work including the work from the gripping rotation start state to the gripping rotation end state of the waste needle collection container 10 shown in FIGS. The cylindrical portion 99b can be easily separated from the distal end 98a of the syringe main body 98 easily. In particular, if the user pays attention to the movement of the hand that repeats the above-described operations including the gripping rotation start state to the gripping rotation end state, the user simply holds the syringe main body 98 in the hand, Since only the extension of C is moved up and down, the waste needle collection container 10 shown in FIGS. 11 and 12 does not require a complicated mechanism or power supply as in the prior art.

  The present invention is not limited to the above-described embodiment. For example, the above-described waste needle collection container is made of a material that can be treated as medical waste together with the injection needle (for example, when the injection needle is formed of stainless steel, the metal used for the waste needle collection container is stainless steel. It is preferable that it is formed by. Moreover, it is needless to say that the specific configurations shown in the embodiments are all exemplifications, and may be replaced with other configurations that exhibit the same effects.
