Description

本発明は、患者の採血に使用する真空採血管用採血針付き採血ホルダーに関する。   The present invention relates to a blood collection holder with a blood collection needle for vacuum blood collection tubes used for blood collection of patients.

近年、採血業務の簡素化、効率化を可能にするために、注射器による採血から真空採血管を使用した採血に移行している。
そして、真空採血管を使用する場合には、従来から真空採血管を着脱可能な採血ホルダーが用いられている。
この採血ホルダーは、採血針とは別体に構成されており、使用時に採血作業者が採血針を採血ホルダーに装着した後、真空採血管を交換しながら採血を行うように構成されている（特許文献１参照）。 In recent years, in order to enable simplification and efficiency of blood collection work, there has been a shift from blood collection using a syringe to blood collection using a vacuum blood collection tube.
And when using a vacuum blood collection tube, the blood collection holder which can attach or detach a vacuum blood collection tube conventionally is used.
The blood collection holder is configured separately from the blood collection needle, and is configured such that blood collection is performed while the blood collection operator attaches the blood collection needle to the blood collection holder during use and then replaces the vacuum blood collection tube ( Patent Document 1).

特開H07−204180号公報JP H07-204180

上記した採血ホルダーは、採血作業者が採血針を着脱できるように構成されているため、採血作業者は患者毎に採血針を交換し、これにより感染症等を予防している。
発明者は、上記した従来の採血方法に着目し、実際には採血中に採血ホルダーに血液が付着する可能性があるため採血針を交換するだけでは十分な感染症の予防にはならず、採血ホルダーごと患者毎に交換するべきであることに着目した。
しかし、採血ホルダーと採血針とが着脱可能に構成されていると、採血ホルダーの患者毎の交換を推奨したとしても、例えば、予備の採血針等が残っている場合には、採血針の交換のみで採血が行われてしまう可能性がある。また、費用の問題から患者ごとに採血ホルダーを交換していても、使用済みの採血ホルダーを洗浄して再利用する場合も考えられる。さらに、採血作業者の立場に立って考えてみても、採血針の交換は採血後の採血針に直接触れてしまう可能性が高いので好ましいとはいえず、また、採血針に直接触れないように採血ホルダーにカバーを設けている例もあるが、採血針を誤って刺してしまう危険を皆無にすることは難しく、作業性の煩雑さもある。
本発明は、上記した従来の問題点を解決し、採血作業者が確実に患者毎に採血ホルダーと採血針とを交換することができ、かつ、採血作業者の作業も軽減させることができる真空採血管用採血針付き採血ホルダーを提供することを目的としている。 Since the blood collection holder is configured such that the blood collection operator can attach and detach the blood collection needle, the blood collection operator replaces the blood collection needle for each patient, thereby preventing infection and the like.
The inventor pays attention to the above-described conventional blood collection method, and in fact, blood may adhere to the blood collection holder during blood collection, so simply replacing the blood collection needle does not sufficiently prevent infection, It was noted that the blood collection holders should be replaced for each patient.
However, if the blood collection holder and the blood collection needle are configured to be detachable, even if it is recommended to replace the blood collection holder for each patient, for example, if a spare blood collection needle remains, replace the blood collection needle. There is a possibility that blood will be collected only by it. In addition, even if the blood sampling holder is replaced for each patient due to cost problems, the used blood sampling holder may be washed and reused. Furthermore, even from the viewpoint of the blood collection operator, replacement of the blood collection needle is not preferable because it is highly likely that the blood collection needle will be directly touched after blood collection, and it should not be touched directly. Although there is an example in which a cover is provided on the blood collection holder, it is difficult to eliminate the risk of accidentally puncturing the blood collection needle, and there is also a problem in workability.
The present invention solves the above-described conventional problems, allows the blood collection operator to surely exchange the blood collection holder and the blood collection needle for each patient, and reduces the work of the blood collection operator. An object of the present invention is to provide a blood collection holder with a blood collection needle for blood collection tubes.

上記した目的を達成するために本発明に係る真空採血管用採血針付き採血ホルダーは、真空採血管を着脱可能な採血ホルダーに、採血針を取外してきないように固定して成ることを特徴とする。
前記採血ホルダーは、例えば、採血ホルダーの一端に、採血ホルダーの外方に向けて突出する採血針装着部を一体的に形成する一方、採血針に、前記採血針装着部内に嵌合可能な外形を有する採血針装着体を一体的に設け、前記採血針装着部及び採血針装着体の少なくとも一方を、採血針装着体を採血針装着部に嵌合する時に、採血ホルダーの軸線方向に略直交する方向に変形可能に構成すると共に、前記採血針装着部及び採血針装着体の何れか一方に切欠部を形成し、他方に前記切欠部に係合可能な突起部を形成し、採血針装着部及び採血針装着体の少なくとも一方を変形させながら、採血針装着体を採血針装着部に嵌合し、前記切欠部に突起部が係止した後に、変形した採血針装着部及び／又は採血針装着体が復元して採血針が採血ホルダーに取外しできないように固定され得る。
また、前記採血ホルダーは、例えば、採血ホルダーの一端に、内面に雌螺子が形成された採血針装着部を設け、採血針に、前記雌螺子と螺合可能な雄螺子を有する採血針装着体を一体的に設け、前記雌螺子及び／又は雄螺子を、一度、螺合した後は取外しできないように構成され得る。
さらに、前記採血ホルダーは、例えば、採血ホルダーの一端に、熱接着樹脂より成る採血針装着部を設け、採血針に、前記採血針装着部に嵌合可能な形状の熱接着樹脂より成る採血針装着体を設け、前記採血針装着体を前記採血針装着部に嵌合した後、採血針装着体と採血針装着部とを接着することにより構成され得る。
好ましくは、採血ホルダーは、真空採血管を抜き差しする採血針の端部を滅菌状態に保持できるようシーリングされ得る。これは、具体的には、例えば、採血ホルダーにおける真空採血管挿入側の端部の全面をシーリングすることにより達成され得るが、例えば、採血ホルダーの内部で真空採血針の端部を保護するように、真空採血針の端部を覆う有底筒状体を採血ホルダーの内部に配置することでも達成され得る。 In order to achieve the above object, a blood collection holder with a blood collection needle for a vacuum blood collection tube according to the present invention is characterized in that the vacuum blood collection tube is fixed to a removable blood collection holder so as not to remove the blood collection needle. .
The blood collection holder, for example, integrally forms a blood collection needle mounting portion that protrudes outward from the blood collection holder at one end of the blood collection holder, while the blood collection needle can be fitted into the blood collection needle mounting portion.

The blood collection needle mounting portion and the blood collection needle mounting body are formed with a notch portion, and the other is formed with a protrusion that can be engaged with the notch portion. The deformed blood collection needle mounting portion and / or blood collection is performed after the blood collection needle mounting body is fitted into the blood collection needle mounting portion while the protrusion is locked to the notch while deforming at least one of the head and the blood collection needle mounting body. The needle attachment is restored and the blood collection needle is It may be fixed as non-removably to chromatography.
In addition, the blood collection holder includes, for example, a blood collection needle mounting body that includes a blood collection needle mounting portion having a female screw formed on an inner surface at one end of the blood collection holder, and the blood collection needle includes a male screw that can be screwed with the female screw. , And the female screw and / or the male screw can be configured so as not to be removed after being screwed once.
Furthermore, the blood collection holder includes, for example, a blood collection needle mounting portion made of a thermoadhesive resin at one end of the blood collection holder, and the blood collection needle is made of a thermoadhesion resin having a shape that can be fitted to the blood collection needle mounting portion. It may be configured by providing a mounting body, bonding the blood sampling needle mounting body to the blood sampling needle mounting section, and then bonding the blood sampling needle mounting body and the blood sampling needle mounting section.
Preferably, the blood collection holder can be sealed so that the end of the blood collection needle for inserting and removing the vacuum blood collection tube can be maintained in a sterilized state. Specifically, this can be achieved, for example, by sealing the entire surface of the end portion on the side of the vacuum blood collection tube in the blood collection holder. For example, the end portion of the vacuum blood collection needle is protected inside the blood collection holder. In addition, the bottomed cylindrical body that covers the end of the vacuum blood collection needle may be disposed inside the blood collection holder.

本発明に係る真空採血管用採血針付き採血ホルダーは、真空採血管を着脱可能な採血ホルダーに、採血針を取外してきないように固定して成るので、採血作業者が採血針を着脱することができない。その結果、例えば、予備の採血針が残っているような状況であっても、確実に患者毎に採血ホルダーと採血針とを交換することが可能であり、また洗浄して再利用することが不可能になるという効果を奏する。これにより、採血による感染症等を確実に予防することができ、また、衛生面での効果も高く、さらに、採血作業者の採血針交換作業を無くすことができるので、採血作業者の作業軽減に繋がる。
また、前記真空採血管用採血針付き採血ホルダーを、例えば、採血ホルダーの一端に、採血ホルダーの外方に向けて突出する採血針装着部を一体的に形成する一方、採血針に、前記採血針装着部内に嵌合可能な外形を有する採血針装着体を一体的に設け、前記採血針装着部及び採血針装着体の少なくとも一方を、採血針装着体を採血針装着部に嵌合する時に、採血ホルダーの軸線方向に略直交する方向に変形可能に構成すると共に、前記採血針装着部及び採血針装着体の何れか一方に切欠部を形成し、他方に前記切欠部に係合可能な突起部を形成し、採血針装着部及び採血針装着体の少なくとも一方を変形させながら、採血針装着体を採血針装着部に嵌合し、前記切欠部に突起部が係止した後に、変形した採血針装着部及び／又は採血針装着体が復元して採血針が採血ホルダーに取外しできないように固定するように構成することにより、採血針をワンタッチで採血ホルダーに装着することができ、しかも、装着後は採血針が採血ホルダーから取り外すことができなくなるので、製造が容易になるという効果を奏する。 The blood collection holder with a blood collection needle for a vacuum blood collection tube according to the present invention is formed by fixing the vacuum blood collection tube to the removable blood collection holder so that the blood collection needle is not removed, so that the blood collection operator can attach and detach the blood collection needle. Can not.
