Description

  The present invention relates to a used syringe needle collection container, and more particularly to a used syringe needle collection container that collects a syringe after separating a syringe barrel and a syringe needle when discarding a used syringe. It is.

  Most of the needles currently in use are disposable from the standpoint of preventing secondary infection, etc., and after use, they are discarded together and incinerated. When discarding the used injection needle, the syringe barrel and the injection needle are separated from each other so as not to pierce the fingertip with a sharp needle tip and cause damage or secondary infection. Therefore, various injection needle collection containers having a mechanism for separating the syringe barrel and the injection needle have been proposed.

  Conventionally proposed injection needle collection containers are roughly classified into those having a simple configuration having a mechanism for simply removing the injection needle (for example, JP 2007-82606 A, JP 2006-204574 A, -6055 and the like) and a mechanism for removing the injection needle and a relatively complicated and large-sized one (for example, Japanese Patent Laid-Open No. 2006-296819) having a mechanism for heating and dissolving.

  The present invention has a simple configuration having the former, that is, a separation mechanism for removing the injection needle. Many of the simple configurations having a needle separation mechanism that have been proposed in the past are provided with an injection needle separation portion comprising an insertion hole at the tip of the injection needle and a sliding groove continuous to the insertion hole at the top of the container. The syringe needle having the tip inserted into the insertion hole is shifted and moved as it is into the sliding groove, and then lifted to remove the injection needle.

  In the case of a conventional used syringe collection container having a conventional syringe needle separation mechanism, the syringe needle is removed from the syringe without touching the syringe needle, and the syringe needle is placed inside the container under the separation portion. In addition to the basic function of collecting the injection needle and syringe, no special ingenuity has been made, and in particular, secondary infection prevention measures and safety considerations when discarding the container after completion of collection Is lacking.

  EMBODIMENT OF THE INVENTION Below, the form for implementing this invention is demonstrated based on an accompanying drawing. FIG. 1 is a perspective view of the injection needle collection container according to the present invention when the lid is opened. As shown therein, the injection needle collection container according to the present invention is provided on the container part 1 and the container part 1. The separation part 11 is detachably fitted. The separation part 11 includes a separation part main body 12 and a lid body 13 that is hinged to the separation part main body 12.

  The separation unit main body 12 includes needle separation means 14 for separating the injection needle 31 from the injection cylinder 32 and a slot 17 into which the injection cylinder (syringe and plunger) 32 from which the injection needle 31 has been removed is dropped. The needle separating means 14 may have the same configuration as that of the conventional one, for example, an insertion hole 15 having a diameter larger than the diameter of the end flange 34 of the needle base 33 that supports the needle tube constituting the injection needle 31. The sliding groove 16 is formed to be continuous with the insertion hole 15. The width of the sliding groove 16 is set to be smaller than the diameter of the end flange of the needle base 33 and larger than the diameter of the needle base fitting portion 34 at the tip of the syringe barrel 32.

  In the preferred embodiment, a pair of needle separating means 14 are arranged so that the insertion holes 15 are inside as shown in the figure. In such a case, it is possible to perform the needle removal operation described later even if it is directed to either the left or right side of the container.

  In the preferred embodiment, the slot 17 into which the syringe barrel 32 including the plunger 35 from which the injection needle 31 has been removed is dropped is provided with a splash prevention plate 17a extending obliquely downward from one opening edge so as to close the opening. . The splash-preventing plate 17a causes blood remaining in the syringe needle 31 that has been separated and dropped to jump up due to the impact of dropping and to come out of the opening of the slot 17 and adhere to the operator's hand. It is for preventing.

  The lid body 13 is normally connected to the separation portion main body 12 via a hinge portion 18 formed to be thin, and rotates from the hinge portion 18 to cover the upper surface of the separation portion main body 12 when the lid is closed. In a preferred embodiment, a recessed portion 19 is formed on the upper surface of the separating portion main body 12, and a fitting portion (thick portion) 20 that fits into the recessed portion 19 is formed on the back surface of the lid 13. . When the fitting portion 20 is closely fitted in the recessed portion 19 when the lid is closed, a stable closed state is maintained. The needle separating means 14 and the slot 17 are provided in the recessed portion 19.

  In a more preferred embodiment, an enclosing wall 21 is formed on the periphery of the upper surface of the separating portion main body 12 except for a folded portion of the lid 13 when the lid is closed, so that the lid 13 is accommodated in the enclosure 21 when the lid is closed. Is done. At this time, the upper surface of the lid 13 is set to be positioned lower than the upper surface of the surrounding wall 21.

  Temporary engaging means and permanent engaging means are formed on the upper surface of the lid 13 and the separation body 12. The temporary engagement means includes, for example, a protrusion 22 formed on one side of the back surface of the lid body 13 and the upper surface of the separation body 12 (in the illustrated example, the back surface of the lid body 13), and the other side. It is formed on the side (in the illustrated example, the upper surface of the separation portion main body 12) and includes a temporary locking hole 23 that fits and holds the protrusion 22 when the lid is closed.

  In the illustrated embodiment, a finger-hanging protrusion 24 is formed on the edge of the lid 13, and a recess 25 is formed in a portion corresponding to the finger-hanging protrusion 24 on the upper surface of the separation body 12. The recess 25 is provided to make it easier to place a finger on the finger-hanging protrusion 24 particularly during the opening operation. In this embodiment, the protrusion 22 is provided on the back surface of the finger hooking protrusion 24. Furthermore, in order to make it easy to put a finger on the end of the finger hooking projection 24, the end may be inclined so as to be obliquely upward when the lid is closed (see FIG. 3).

  The permanent engagement means includes, for example, a locking projection 26 formed at the end of the lid body 13, and a permanent locking hole 27 formed on the upper surface of the separation unit main body 12 and into which the locking projection 26 is fitted. It is supposed to consist of The locking projection 26 has a trapezoidal shape that expands from the distal end toward the proximal end, and is slightly elastically deformable in the width direction. In the illustrated embodiment, the locking projection 26 is formed on the edge of the lid body 13. A pair of protrusions are provided with the finger-hanging protrusion 24 interposed therebetween. In a preferred embodiment, the base portion of the locking projection 26 can be bent by being thinned or the like. The permanent locking hole 27 is set to a length that is slightly shorter than the maximum width of the locking protrusion 26 (width when no load is applied).

  This permanent engaging means is provided to prevent the lid 13 from being inadvertently opened after the lid 13 is closed when the container is discarded, and to prevent the collected material from spilling out. In the case of the form, the lid 13 is closed in a state where the locking projection 26 is bent from the base portion to the back surface side, and the locking projection 26 is inserted into the permanent locking hole 27. At this time, since the length of the permanent locking hole 27 is set shorter than the maximum width of the locking projection 26, there is resistance to pushing, but the locking projection 26 can be slightly elastically deformed in the width direction. Therefore, when forcibly pushed in, the locking projection 26 can shrink in the width direction and pass through the permanent locking hole 27.

  Then, after the locking protrusion 26 passes through the permanent locking hole 27, it immediately expands to its original state by its restoring force and is hooked on the inner edge of the permanent locking hole 27. (See FIG. 7). Thus, after the lid 13 is closed when the container is discarded, the lid 13 is surely prevented from being opened carelessly and the collected material is prevented from spilling out. In addition, there is no risk of secondary infection caused by spilling residual liquid on the floor.

  When this container is used, the lid 13 is opened by placing a finger on the finger-hanging projection 24, the injection needle 31 portion of the used syringe is inserted into the insertion hole 15, and is shifted laterally as it is in the sliding groove 16. Then, the injection needle 31 is removed by pulling up the syringe barrel 32. This operation is the same as in the case of the conventional collection container. The separated injection needle 31 is dropped as it is and collected in the container part 1. At this time, since the splash prevention plate 17a is provided in the slot 17, the blood remaining in the injection needle 31 is prevented from jumping out of the slot 17 due to the impact of dropping. In addition, the syringe barrel 32 including the plunger 35 from which the injection needle 31 has been removed is recovered into the container 1 by being dropped into the slot 17.

  After the completion of this operation, the lid 13 is closed and the protrusion 22 is fitted into the temporary locking hole 23 so that the openable / closable state is maintained, and the next separation operation is awaited. When this separation operation is repeated and the inside of the container part 1 becomes full, the collected material is discarded together with the container. In this disposal, when the lid 13 is closed, the locking projection 26 is bent and forcedly pushed into the permanent locking hole 27. Thereby, as mentioned above, the locking projection 26 is locked to the inner edge of the permanent locking hole 27 and cannot be removed.

  Further, the surrounding wall 21 is provided on the periphery of the upper surface of the separation unit main body 12, and when the lid is closed, the upper surface of the lid body 13 is positioned lower than the upper surface of the surrounding wall 21. Since it is set to a size that can be accommodated, another main container can be stacked in a stable state on the portion, which is convenient during transportation and storage.
