Description

本発明は、使用済みの注射針を注射器本体から取り外して廃棄するための注射針廃棄用容器に関する。   The present invention relates to a syringe needle disposal container for removing a used syringe needle from a syringe body and discarding it.

病院等で使用される注射器には、注射針のハブが注射器本体の先端部に着脱自在に差し込まれる差込式タイプの注射器と、注射針のハブが注射器本体の先端部に着脱自在に螺着されるネジ式タイプの注射器とがある。このような注射器は、感染症防止のために、使用後には注射器本体と注射針とに分別して廃棄される。その際、作業者が直接手で注射針を把持して注射器本体から取り外すと、誤って自身の手指などを注射針で傷付けるおそれがある。   For syringes used in hospitals, etc., an insertion type syringe in which the hub of the injection needle is detachably inserted into the tip of the syringe body and a hub of the injection needle are detachably screwed to the tip of the syringe body. And a screw-type syringe. In order to prevent infection, such a syringe is discarded after being separated into a syringe body and a needle. At this time, if the operator directly holds the injection needle with his hand and removes it from the syringe body, his / her finger may be accidentally damaged by the injection needle.

そこで、従来より、使用済みの注射針を注射器本体から安全に取り外して廃棄することができる注射針廃棄用容器が利用されている（例えば、特許文献１参照）。この注射針廃棄用容器は、医療廃棄物を収容するための容器本体と、容器本体の開口部を覆う蓋体と、を備えている。蓋体には、注射針が挿入される注射針挿入孔と、この注射針挿入孔から両側に延びる一対の凹部とが設けられている。   Therefore, conventionally, a syringe disposal container that can safely remove a used syringe needle from the syringe body and discard it has been used (see, for example, Patent Document 1). The injection needle disposal container includes a container body for storing medical waste and a lid that covers an opening of the container body. The lid is provided with an injection needle insertion hole into which the injection needle is inserted, and a pair of recesses extending from the injection needle insertion hole to both sides.

差込式タイプの注射器において注射針を廃棄するときには、まず、注射針のハブを注射針挿入孔に挿入し、この挿入した状態のままで注射器を凹部に沿ってスライド移動させる。その後、注射器を揺動することによってハブに下方への押圧力が作用し、これによりハブが注射器本体の先端部から取り外され、注射針が凹部を通して容器本体内に落下して収容される。   When discarding the injection needle in the plug-in type syringe, first, the hub of the injection needle is inserted into the injection needle insertion hole, and the syringe is slid along the recess while being inserted. Thereafter, a downward pressing force acts on the hub by swinging the syringe, whereby the hub is removed from the distal end portion of the syringe body, and the injection needle falls into the container body through the recess and is accommodated.

また、移動部材４８が保持解除位置に位置付けられると、移動部材４８の他端部が装着用凹部４６の他端部に接触乃至近接され、第２保持部６４が第１保持部５４より離隔して落下開口部６２が開放される。   When the moving member 48 is positioned at the holding release position, the other end portion of the moving member 48 comes into contact with or close to the other end portion of the mounting recess 46, and the second holding portion 64 is separated from the first holding portion 54. Thus, the drop opening 62 is opened.

更に、移動部材４８に関連して、移動部材４８を保持位置にロック保持するためのロック機構が設けられている。このロック機構は、移動部材４８の下方において装着用凹部４６の中央部に傾動自在に設けられた傾動部材７８と、移動部材４８の下面に設けられたロック用突部８０とから構成されている。傾動部材７８の先端部には、ロック用爪部８２が上方に幾分突出して設けられ、このロック用爪部８２の先端部には第１テーパ部８６が形成されている。また、ロック用突部８０の先端部には、ロック用爪部８２の第１テーパ部８４に対応して第２テーパ部８４が形成されている。 Further, in association with the moving member 48, a lock mechanism for locking and holding the moving member 48 in the holding position is provided. This locking mechanism is composed of a tilting member 78 that is tiltably provided at the center of the mounting recess 46 below the moving member 48, and a locking projection 80 that is provided on the lower surface of the moving member 48. . A locking claw portion 82 protrudes somewhat upward from the distal end portion of the tilting member 78, and a first taper portion 86 is formed at the distal end portion of the locking claw portion 82. Further, a second taper portion 84 is formed at the distal end portion of the locking projection 80 so as to correspond to the first taper portion 84 of the locking claw portion 82.

傾動部材７８の上面の一部には、その基端部側から先端部側に向けて上り傾斜となる傾斜面８８が設けられている（図８参照）。また、移動部材４８には楕円形状の操作用開口部９０が設けられ、この操作用開口部９０を通して傾動部材７８の上面（傾斜面８８）が外部に露出されている。操作用開口部９０の縁部には、リング状の操作用突部９２が上方に幾分突出して設けられている。   A part of the upper surface of the tilting member 78 is provided with an inclined surface 88 that is inclined upward from the proximal end side toward the distal end side (see FIG. 8). The moving member 48 is provided with an elliptical opening 90 for operation, and the upper surface (inclined surface 88) of the tilting member 78 is exposed to the outside through the opening 90 for operation.

また、装着用凹部４６には、ロック用突部８０の移動経路に沿って延びる移動用開口部９４が設けられている。移動部材４８の他端部には目隠し部９６が設けられ、この目隠し部９６は、下方にＬ字状に延びている。移動部材４８が保持位置に位置付けられた際に、この目隠し部９６によって移動用開口部９４の一部が下方より覆われるようになる。   The mounting recess 46 is provided with a movement opening 94 extending along the movement path of the locking projection 80. A blindfold 96 is provided at the other end of the moving member 48, and the blindfold 96 extends downward in an L shape. When the moving member 48 is positioned at the holding position, a part of the moving opening 94 is covered by the blindfold 96 from below.

なお、移動部材４８の下面において、操作用開口部９０と第２保持部６４との間にはぬすみ部９８が設けられている。このぬすみ部９８によって、移動部材４８が保持解除位置に位置付けられた際に、傾動部材７８の上面と移動部材４８とが互いに接触されるのが防止される（図９参照）。   Note that, on the lower surface of the moving member 48, a lightening portion 98 is provided between the operation opening 90 and the second holding portion 64. When the moving member 48 is positioned at the holding release position, the thinning portion 98 prevents the upper surface of the tilting member 78 and the moving member 48 from contacting each other (see FIG. 9).

次に、上述した注射針廃棄用容器２を用いて、ネジ式タイプの注射器２４の注射針２６を廃棄する方法について説明する。まず、移動部材４８が保持位置に位置付けられた状態で、使用済みの注射針２６のハブ３６を注射針保持部７２の上端開口部よりその内部に挿入する（図８参照）。注射器本体２８の筒状部３２の下端部が注射針保持部７２の上端開口部の外周部に接触されるまで挿入すると、ハブ３６が注射針保持部７２に着脱自在に保持される。この状態では、ハブ３６の上側部（基端部側）における外周面がハブ保持用凹部７４に着脱自在に保持されるとともに、複数の係合用突部４０が複数の係合用凹部７６に着脱自在に係合される。これにより、注射針２６の注射針保持部７２に対する回転が拘束される。   Next, a method of discarding the injection needle 26 of the screw type syringe 24 using the above-described injection needle disposal container 2 will be described. First, with the moving member 48 positioned at the holding position, the used hub 36 of the injection needle 26 is inserted into the inside of the upper end opening of the injection needle holding portion 72 (see FIG. 8). When the lower end of the cylindrical portion 32 of the syringe main body 28 is inserted until it comes into contact with the outer peripheral portion of the upper end opening of the injection needle holding portion 72, the hub 36 is detachably held by the injection needle holding portion 72. In this state, the outer peripheral surface of the upper portion (base end side) of the hub 36 is detachably held by the hub holding recess 74, and the plurality of engaging protrusions 40 are detachably attached to the plurality of engaging recesses 76. Is engaged. Thereby, rotation with respect to the injection needle holding | maintenance part 72 of the injection needle 26 is restrained.

かかる状態で、注射器本体２８を注射針２６に対して図８中の矢印Ｐで示す方向に回転させると、ハブ３６の一対のネジ突部４２と筒状部３２の２条ネジ部３４との螺合が解除され、注射器本体２８がハブ３６より取り外される。このとき、移動部材４８がロック機構によって保持位置にロック保持されているので、注射器本体２８を注射針２６に対して回転させる際に、移動部材４８が保持解除位置にスライド移動されるのが防止される。   In this state, when the syringe body 28 is rotated with respect to the injection needle 26 in the direction indicated by the arrow P in FIG. 8, the pair of screw protrusions 42 of the hub 36 and the double threaded portion 34 of the cylindrical portion 32 are connected. The screwing is released, and the syringe body 28 is removed from the hub 36. At this time, since the moving member 48 is locked and held at the holding position by the locking mechanism, the moving member 48 is prevented from being slid to the holding releasing position when the syringe body 28 is rotated with respect to the injection needle 26. Is done.

その後に、手指などを操作用開口部９０に挿入して傾動部材７８の上面を下方に押圧し、傾動部材７８を下方に傾動させてロック解除位置に位置付ける。この状態のままで、手指などを操作用突部９２に引っ掛けるなどして、移動部材４８を保持位置から保持解除位置にスライド移動させると、注射針２６が所定方向に傾いてハブ３６が注射針保持部７２から離脱され、注射針２６が落下開口部６２を通して容器本体４内に落下して収容される。   Thereafter, a finger or the like is inserted into the operation opening 90 to press the upper surface of the tilting member 78 downward, and the tilting member 78 is tilted downward to be positioned at the unlocking position. In this state, when the moving member 48 is slid from the holding position to the holding release position by hooking a finger or the like on the operation protrusion 92, the injection needle 26 is tilted in a predetermined direction, and the hub 36 is moved to the injection needle. The needle 26 is detached from the holding portion 72 and is dropped into the container body 4 through the drop opening 62 and accommodated.

注射針２６が容器本体４内に収容された後には、手指などを操作用突部９２に引っ掛けるなどして、移動部材４８を保持解除位置から保持位置にスライド移動させる。このとき、ロック用爪部８２の第１テーパ部８４がロック用突部８０の第２テーパ部８６上をスライドすることによって、傾動部材７８が下方に傾動され、ロック用爪部８２がロック用突部８０に再び係合される。   After the injection needle 26 is accommodated in the container body 4, the moving member 48 is slid from the holding release position to the holding position by hooking a finger or the like on the operation protrusion 92. At this time, when the first taper portion 84 of the locking claw portion 82 slides on the second taper portion 86 of the locking projection 80, the tilting member 78 is tilted downward, and the locking claw portion 82 is locked. The protrusion 80 is engaged again.

上述したように、本実施形態の注射針廃棄用容器２では、ネジ式タイプの注射器２４において、注射針２６を注射器本体２８から容易に取り外して廃棄することができる。   As described above, in the syringe needle disposal container 2 of the present embodiment, in the screw type syringe 24, the syringe needle 26 can be easily detached from the syringe body 28 and discarded.

本実施形態の注射針廃棄用容器２Ａでは、移動部材４８Ａを保持解除位置に向けて弾性的に偏倚するためのコイルバネ１００（弾性偏倚手段を構成する）が設けられている。このコイルバネ１００の一端部は、移動部材４８Ａの目隠し部９６の先端部に支持され、その他端部は、装着部４４Ａの下面に設けられたブラケット１０２に支持されている。   In the injection needle discarding container 2A of the present embodiment, a coil spring 100 (constituting an elastic biasing means) is provided for elastically biasing the moving member 48A toward the holding release position. One end of the coil spring 100 is supported by the tip of the blindfold 96 of the moving member 48A, and the other end is supported by the bracket 102 provided on the lower surface of the mounting portion 44A.

従って、傾動部材７８をロック位置からロック解除位置に傾動させると、このコイルバネ１００の弾性偏倚力によって、移動部材４８Ａを保持位置から保持解除位置に容易にスライド移動させることができる。   Therefore, when the tilt member 78 is tilted from the lock position to the lock release position, the moving member 48A can be easily slid from the holding position to the holding release position by the elastic biasing force of the coil spring 100.

It is slid freely between a holding release position where the drop opening is opened further apart. As a result, when discarding the injection needle of the screw type syringe, the moving member is positioned at the holding position, and the syringe body is held against the injection needle with the hub of the injection needle held by the injection needle holding portion. By rotating in a predetermined direction, the screwing between the hub and the tip of the syringe body can be released. Thereafter, the moving member is positioned at the holding release position, so that the injection needle falls into the container main body through the drop opening, and the injection needle can be accommodated in the container main body and discarded. Thus, in a screw type syringe, the injection needle can be easily removed from the syringe body and discarded.
