Description

本発明は注射針用廃棄容器に関する。さらに詳しくは、注射器本体の先端に注射針保持体を介して螺合された注射針を片手で安全かつ簡単に取り外して廃棄することができる注射針用廃棄容器に関する。   The present invention relates to a waste container for a syringe needle. More specifically, the present invention relates to a syringe waste container that can safely and easily be removed and discarded by one hand with a syringe needle screwed to the tip of a syringe body via a syringe needle holder.

病院などで使用される注射器は、一般に、注射針を合成樹脂製の保持部（ハブ）などを介して注射器本体の吐出管に差し込んだ、いわゆる差込み式の注射器が用いられている。使用済の注射針は、１回の注射ごとに毎回新品の針と交換するために取り外されなければならない。使用済みの注射針を取り外して廃棄する作業は、作業者が直接手で注射針または保持チューブを把持して行なえば、手または指を使用済みの注射針で傷つける場合があり、好ましくない。   In general, a syringe used in a hospital or the like is a so-called plug-in type syringe in which an injection needle is inserted into a discharge pipe of a syringe body via a synthetic resin holding portion (hub). A used needle must be removed to replace a new needle after each injection. The operation of removing and discarding the used injection needle is not preferable if the operator directly grips the injection needle or the holding tube with his / her hand, and the hand or finger may be damaged by the used injection needle.

そこで、従来より、使用済みの注射針を安全に注射器本体から取り外すことができる注射針用廃棄容器が種々提案されている。このような廃棄容器として、たとえば、容器の蓋体に対し、注射器の先端に差し込まれている使用済みの注射針を取り外すために、注射針の挿入孔と連続して注射針を取り外すための係止溝が形成された使用済み注射針廃棄用容器が提案されている（たとえば、特許文献１参照）。   Therefore, various types of syringe waste containers that can safely remove a used syringe needle from the syringe body have been proposed. As such a waste container, for example, in order to remove the used injection needle inserted into the tip of the syringe with respect to the lid of the container, a member for removing the injection needle continuously with the insertion hole of the injection needle. A used syringe needle disposal container in which a stop groove is formed has been proposed (see, for example, Patent Document 1).

一方、最近では、糖尿病患者が１日に数回程度定期的に自分でインシュリンを注射するためなどに用いられる注射器として、ペン型注射器が種々提案されている。このようなペン型注射器では、注射器本体の先端に対し、注射針が注射針保持体を介して螺合されている、いわゆるねじ式の注射器が多い。   On the other hand, recently, various pen-type syringes have been proposed as syringes used for diabetic patients to regularly inject insulin themselves several times a day. In such a pen-type syringe, there are many so-called screw-type syringes in which an injection needle is screwed to the tip of the syringe body via an injection needle holder.

このようなねじ式の注射器では、使用済みの注射針を注射器本体から取り外す場合に、注射針保持体と注射器本体との螺合を解除する動作が必要であり、従来の差込み式の注射器に適用される廃棄容器を用いて取り外すことができなかった。したがって、従来では、作業に不慣れな糖尿病患者などが使用済みの注射針を直接手で取り外さなくてはならず、安全性に問題があるとともに作業に時間がかかるという問題がある。   In such a screw type syringe, when the used injection needle is removed from the syringe body, it is necessary to release the screwing between the injection needle holder and the syringe body, which is applicable to the conventional insertion type syringe. Could not be removed using the discarded waste container. Therefore, conventionally, a diabetic patient who is unfamiliar with work has to remove a used injection needle directly by hand, which is problematic in terms of safety and time.

本発明はかかる問題を解消するためになされたものであり、注射器本体の先端に注射針保持体を介して螺合された注射針を、片手で安全かつ簡単に取り外して廃棄することができる注射針用廃棄容器を提供することを目的とする。   The present invention has been made to solve such a problem, and an injection needle that can be safely and easily removed and discarded with one hand by an injection needle screwed into the tip of a syringe body via an injection needle holder. The purpose is to provide a waste container for needles.

FIG. 6 is an explanatory view showing a state in which the injection needle stays inside the insertion hole of the waste container. FIG. 6 is a plan view of the insertion hole having a meshing portion including a plurality of meshing protrusions and meshing grooves of the waste container of FIG. These are the top views of the insertion hole which has a meshing part which consists of two meshing grooves which shows other embodiment of this invention.

図１〜２に示される注射針用廃棄容器は、図３に示される、注射器本体２２の先端に注射針保持体２３を介して注射針２４が螺合されたペン型注射器２１の注射針２４を廃棄するための容器である。この廃棄容器は、容器本体１と、該容器本体１の上面を覆う蓋２とからなる。容器本体１の上面３には、注射針保持体２３を挿入するための挿入孔４が容器本体１の軸方向の中心から外れた位置に１個形成されている。   The injection needle disposal container shown in FIGS. 1 and 2 is an injection needle 24 of a pen-type injector 21 shown in FIG. 3 in which an injection needle 24 is screwed onto the tip of a syringe body 22 via an injection needle holder 23. It is a container for discarding. The disposal container includes a container body 1 and a lid 2 that covers the upper surface of the container body 1. One insertion hole 4 for inserting the injection needle holder 23 is formed in the upper surface 3 of the container body 1 at a position deviated from the axial center of the container body 1.

なお、本実施の形態では、１個の挿入孔４が容器本体１の上面３に形成されているが、本発明はこれに限定されるものではなく、廃棄容器を構成する面のうちの少なくとも１つの面において、前記注射針保持体を挿入するための挿入孔が少なくとも１個形成されていればよく、たとえば、容器本体の上面に複数個の挿入孔を形成してもよいし、また、容器本体の側面に挿入孔を形成してもよい。   In the present embodiment, one insertion hole 4 is formed in the upper surface 3 of the container body 1, but the present invention is not limited to this, and at least of the surfaces constituting the waste container. It is only necessary that at least one insertion hole for inserting the injection needle holder is formed on one surface, for example, a plurality of insertion holes may be formed on the upper surface of the container body, An insertion hole may be formed on the side surface of the container body.

挿入孔４は、注射針保持体２３の外形とほぼ同じ大きさを有しており、該挿入孔４の近傍には、注射針保持体２３の外周面に形成された凸部２３ａおよび／または凹部２３ｂと噛み合うことにより、当該注射針保持体２３の回転を禁止する噛合部が設けられている。本実施の形態の噛合部は、図４〜６に示されるように、挿入孔４の内周縁に当該挿入孔４の内方を向いて突設された複数本の噛合突起５と、前記挿入孔４の内周縁から当該挿入孔４の外方を向いて形成された複数本の噛合溝６とからなる。   The insertion hole 4 has substantially the same size as the outer shape of the injection needle holder 23. In the vicinity of the insertion hole 4, a convex portion 23a formed on the outer peripheral surface of the injection needle holder 23 and / or A meshing portion that prohibits rotation of the injection needle holder 23 by meshing with the recess 23b is provided. As shown in FIGS. 4 to 6, the meshing portion of the present embodiment includes a plurality of meshing protrusions 5 protruding from the inner periphery of the insertion hole 4 toward the inner side of the insertion hole 4, and the insertion It consists of a plurality of meshing grooves 6 formed from the inner peripheral edge of the hole 4 to the outside of the insertion hole 4.

容器本体１は、たとえばブリキまたはスチールなどの金属製の缶などからなり、円筒状の胴体の上下に天板および底板が巻き締められることにより、容器本体１が作製されている。なお、容器本体１の形状や寸法は、本発明において、とくに限定されるものではなく、たとえば円筒形状以外に、立方体や直方体などの他の形状を採用することができる。   The container main body 1 is made of, for example, a metal can such as tinplate or steel, and the container main body 1 is manufactured by winding a top plate and a bottom plate on the top and bottom of a cylindrical body. The shape and dimensions of the container main body 1 are not particularly limited in the present invention, and other shapes such as a cube and a rectangular parallelepiped can be adopted in addition to the cylindrical shape, for example.

本実施の形態では、さらに、図１〜２に示されるように、容器本体１の上面３を覆う蓋２が回転自在に設けられている。この蓋２は容器本体１にネジ込むようにしてもよいし、単に容器本体１の上面を摺動させるようにしてもよい。蓋２は、容器本体１と同様に金属で作製してもよいし、合成樹脂など他の材質で作製してもよい。   In the present embodiment, as shown in FIGS. 1 and 2, a lid 2 that covers the upper surface 3 of the container body 1 is rotatably provided. The lid 2 may be screwed into the container body 1 or may simply be slid on the upper surface of the container body 1. The lid 2 may be made of metal like the container body 1 or may be made of other materials such as synthetic resin.

蓋２には、容器本体１上面の挿入孔４を外部に露出させるための露出孔７が形成されている。露出孔７は、挿入孔４よりも若干大きく、容器本体１の軸方向の中心から挿入孔４までの距離と同じ距離程度、当該容器本体１の軸方向の中心から外れた位置に形成されている。したがって、廃棄容器の挿入孔４は、廃棄容器を使用しないときは蓋２で覆い隠すことができ、容器内部に蓄積された使用済の注射針などが外部にこぼれ出る心配がない。また、誤って挿入孔４の噛合突起５に触れて、ケガをするのを防ぐことができる。一方、廃棄容器を使用するときには、蓋２を回転させて露出孔７と挿入孔４の位置を一致させるだけで、挿入孔４を容易に外部に露出させることができ、使用済の注射針などを廃棄することができる。なお、本実施の形態では、蓋２に露出孔７を形成しているが、形成しなくてもよい。   The lid 2 is formed with an exposure hole 7 for exposing the insertion hole 4 on the upper surface of the container body 1 to the outside. The exposure hole 7 is slightly larger than the insertion hole 4 and is formed at a position away from the axial center of the container body 1 by the same distance as the distance from the axial center of the container body 1 to the insertion hole 4. Yes. Therefore, when the waste container is not used, the insertion hole 4 of the waste container can be covered with the lid 2, and there is no fear that the used injection needle accumulated in the container spills out. Further, it is possible to prevent injury by touching the meshing protrusion 5 of the insertion hole 4 by mistake. On the other hand, when the waste container is used, the insertion hole 4 can be easily exposed to the outside simply by rotating the lid 2 so that the positions of the exposure hole 7 and the insertion hole 4 coincide with each other. Can be discarded. In the present embodiment, the exposure hole 7 is formed in the lid 2, but it may not be formed.

噛合突起５は、注射針保持体２３の外周に形成された凹部２３ｂに噛み合うことにより、注射針保持体２３の回転を止めることができる程度の寸法および本数が選定されていればよい。   The engagement protrusion 5 may be selected to have a size and number that can stop the rotation of the injection needle holder 23 by engaging with a recess 23 b formed on the outer periphery of the injection needle holder 23.

噛合溝６は、注射針保持体２３の外周に形成された凸部２３ａと噛み合うことにより、注射針保持体２３の回転を止めることができる程度の寸法および本数が選定されていればよい。   The engagement groove 6 only needs to be selected to have a size and the number that can stop the rotation of the injection needle holder 23 by engaging with the convex portion 23 a formed on the outer periphery of the injection needle holder 23.

本実施の形態では、図５に示されるように、複数本の噛合突起５および噛合溝６が放射状に配置されているが、本発明はこれに限定されるものではなく、注射針保持体２３の外周面に形成された凸部２３ａおよび／または凹部２３ｂと噛み合うことにより、当該注射針保持体の回転を禁止することができれば、種々の態様を採用することができる。すなわち、噛合部５および噛合溝６は、いずれか一方だけを形成することもできるし、その数は１つでもよいし、複数であってもよい。たとえば、本発明の他の実施の形態として、図７に示されるように、前記注射針保持体２３の外周面に凸部２３ａが２本形成されている場合に対応して、噛合溝６を２本有する噛合部を採用しても注射針保持体２３の回転を禁止することができる。また、これとは逆に、２本の噛合突起５を対向する位置に形成し、この噛合突起５を注射針保持体２３の外周の凹部２３ｂと噛み合わせて当該注射針保持体２３の回転を禁止するようにすることもできる。   In the present embodiment, as shown in FIG. 5, the plurality of meshing protrusions 5 and the meshing grooves 6 are arranged radially, but the present invention is not limited to this, and the injection needle holder 23. If the rotation of the injection needle holder can be prohibited by meshing with the convex portion 23a and / or the concave portion 23b formed on the outer peripheral surface, various modes can be adopted. That is, only one of the meshing part 5 and the meshing groove 6 can be formed, or the number thereof can be one or plural. For example, as another embodiment of the present invention, as shown in FIG. 7, the engagement groove 6 is formed corresponding to the case where two convex portions 23 a are formed on the outer peripheral surface of the injection needle holder 23. Even if two meshing portions are employed, the rotation of the injection needle holder 23 can be prohibited. On the contrary, two engaging protrusions 5 are formed at opposing positions, and the engaging protrusions 5 are engaged with the recesses 23b on the outer periphery of the injection needle holder 23 to rotate the injection needle holder 23. It can also be prohibited.

前記噛合突起５および噛合溝６を含む噛合部は、容器本体１の上面を構成する金属薄板を打ち抜くことにより、挿入孔４とともに形成すれば、容易にかつ少ない工程で形成することができる。   The meshing portion including the meshing protrusion 5 and the meshing groove 6 can be formed easily and with few steps if it is formed together with the insertion hole 4 by punching out a metal thin plate constituting the upper surface of the container body 1.

図３に示されるペン型注射器２１は、糖尿病患者が１日に数回程度定期的に自分でインシュリンを注射するためなどに用いられる注射器として、広く世界的に市販されているものである。このペン型注射器２１では、注射器本体２２の先端に形成されたおねじ部２５に、注射針２４が固着された注射針保持体２３の内周面に形成されためねじ部２６を螺合させることにより、注射針保持体２３を注射器本体２２の先端に着脱自在に螺合することができる。   The pen-type syringe 21 shown in FIG. 3 is widely marketed worldwide as a syringe that is used for diabetic patients to inject insulin by themselves regularly several times a day. In this pen-type syringe 21, a threaded portion 26 is screwed into a male threaded portion 25 formed at the distal end of the syringe body 22 and is formed on the inner peripheral surface of the syringe needle holder 23 to which the syringe needle 24 is fixed. Thus, the injection needle holder 23 can be detachably screwed onto the tip of the syringe body 22.

以上のように構成された廃棄容器を用いて、図３のペン型注射器２１の注射器本体２２の先端に螺合された注射針（具体的には、注射針２４が固着された注射針保持体２３）を使用後に取り外して廃棄する場合、蓋２を回転させて露出孔７を挿入孔４に合わせたのち、図４に示されるように、ペン型注射器２１を下向きにして、注射針保持体２３を挿入孔４に挿入する。それにより、注射針保持体２３の外周面に形成された凹部２３ｂおよび凸部２３ａがそれぞれ、挿入孔４内周縁の噛合突起５および噛合溝６がそれぞれ噛合し、注射針保持体２３が回転できないように固定される。この状態で、ペン型注射器２１を片手で回転させれば、注射器本体２２のみ回転し、噛合突起５および噛合溝６により固定された注射針保持体２３は注射器本体２２との噛合が解除される。   Using the waste container configured as described above, a syringe needle (specifically, a syringe needle holder to which the syringe needle 24 is fixed) is screwed into the tip of the syringe body 22 of the pen-type syringe 21 of FIG. 23) is removed after use and discarded, the lid 2 is rotated to align the exposure hole 7 with the insertion hole 4, and then, as shown in FIG. 23 is inserted into the insertion hole 4. Thereby, the concave portion 23b and the convex portion 23a formed on the outer peripheral surface of the injection needle holder 23 are respectively engaged with the engagement protrusion 5 and the engagement groove 6 on the inner peripheral edge of the insertion hole 4, and the injection needle holder 23 cannot rotate. To be fixed. If the pen-type syringe 21 is rotated with one hand in this state, only the syringe main body 22 is rotated, and the injection needle holder 23 fixed by the engagement protrusion 5 and the engagement groove 6 is released from engagement with the injection body 22. .

そののち、注射器本体２２を持ち上げれば、図５に示されるように、注射針保持体２３の外周面における凹部２３ｂが形成されていないフランジ部２３ｃが噛合突起５に係合した状態で、注射針保持体２３は挿入孔４内部に留まっている。挿入孔４内部に留まっている注射針保持体２３は、たとえば次回に使用済の注射針を廃棄する際に、廃棄容器内部に押し込まれて容器底部に落とされる。この場合に、本実施の形態における噛合突起５は弾性を有しており、バネのような機能を有するので、注射針を落とし込んだのちに、たとえ容器を逆さにしたとしても、挿入孔４から注射針が抜け出るのを確実に防ぐことができる。   Thereafter, when the syringe body 22 is lifted, the injection is performed in a state where the flange portion 23c in which the concave portion 23b is not formed on the outer peripheral surface of the injection needle holder 23 is engaged with the meshing protrusion 5 as shown in FIG. The needle holder 23 remains inside the insertion hole 4. The syringe needle holder 23 staying inside the insertion hole 4 is pushed into the disposal container and dropped to the bottom of the container when the used syringe needle is discarded next time, for example. In this case, the meshing protrusion 5 in the present embodiment has elasticity and functions like a spring. Therefore, even if the container is inverted after dropping the injection needle, It is possible to reliably prevent the injection needle from coming out.

なお、注射針保持体２３にフランジ部２３ｃがなく、凹部２３ｂが保持体の全長にわたって形成されている場合には、注射針保持体２３は、注射器本体２２との噛合が解除されると同時に、廃棄容器の底部に落下する。   In addition, when the injection needle holder 23 has no flange portion 23c and the recess 23b is formed over the entire length of the holder, the injection needle holder 23 is released from meshing with the syringe body 22, Fall to the bottom of the waste container.

注射針の廃棄完了後、蓋２を回転させて露出孔７を挿入孔４と重ならない位置まで移動させれば、挿入孔４は蓋２により外部から覆い隠される。   After the disposal of the injection needle is completed, if the cover 2 is rotated to move the exposure hole 7 to a position where it does not overlap the insertion hole 4, the insertion hole 4 is covered with the cover 2 from the outside.
