Description
本発明は採血管ホルダ、針カバー、血液バッグの構成部品並びに血液バッグの改良に関する。 The present invention relates to a blood collection tube holder, a needle cover, a blood bag component, and an improvement of the blood bag.
特許文献１には、血液のサンプリングチューブの一端にサンプリング針を装着し、他方の端部に採血管ホルダを装着し、サンプリングチューブの途中に針カバーを装着した血液バッグの構成部品の発明が開示されている。
当該発明の使用方法を例示すると下記の通りである。
（１）サンプリング針を供血者に穿刺し、血液をサンプリングチューブを経て、サンプリング針を経て、試験管に採取する。
（２）上記作業が完了したら、サンプリング針を針カバー内に収納し、当該針カバーを採血管ホルダ内に挿入して、廃棄する。
当該発明では、細径の針カバーを大径の採血管ホルダ内に収納して廃棄することはできるが、細径の針カバーが、採血管ホルダから飛び出して、サンプリング針に付着している血液が作業者にも付着することがあり、衛生的に好ましくない。
Patent Document 1 discloses an invention of a blood bag component in which a sampling needle is attached to one end of a blood sampling tube, a blood collection tube holder is attached to the other end, and a needle cover is attached in the middle of the sampling tube. Has been.
The usage method of the present invention is exemplified as follows.
(1) A blood donor is punctured with a sampling needle, and blood is collected into a test tube through the sampling tube and the sampling needle.
(2) When the above operation is completed, the sampling needle is stored in the needle cover, and the needle cover is inserted into the blood collection tube holder and discarded.
In the present invention, the small-diameter needle cover can be stored in the large-diameter blood collection tube holder and discarded, but the small-diameter needle cover protrudes from the blood collection tube holder and adheres to the sampling needle. May also adhere to the operator, which is not hygienic.
特許文献２には、採血管ホルダと針カバーそれぞれに、相互に係合可能な部材（突起、溝等）を形成し、針カバー（先端の）開口端に、採血管ホルダのサンプリング針が入るように、針カバーを採血管ホルダに深く挿入するようにした、採血管ホルダ、針カバー、血液バッグの構成部品並びに血液バッグの発明が開示されている。
当該発明は、特許文献１に記載の発明の欠点は解消されたが、針カバーを採血管ホルダの奥深くまで挿入する形態であるため、奥深くまで挿入する操作に手間どり、操作上の難点があった。
特許文献３には、採血針全体を収納可能であるとともに、当該採血針全体を収納した状態において、採血針基と係合し、採血針の脱落を抑制する係合部を内面に形成した針カバーの発明が開示されている。
針カバー内面に係合部（突起等）を形成するには、採血針基が係合部（突起等）を乗り越えて、係合できるように形成しなければならないので、設計が必ずしも容易ではない。
また当該発明には、採血管ホルダとの係合構造等については何ら記載されていない。
In Patent Document 2, members (protrusions, grooves, etc.) that can be engaged with each other are formed in each of the blood collection tube holder and the needle cover, and the sampling needle of the blood collection tube holder enters the opening end of the needle cover (at the tip). Thus, the invention of a blood collection tube holder, a needle cover, a blood bag component, and a blood bag, in which the needle cover is inserted deeply into the blood collection tube holder, is disclosed.
Although the present invention has solved the disadvantages of the invention described in Patent Document 1, since the needle cover is inserted deep into the blood collection tube holder, the operation of inserting the needle cover deeply is troublesome and there are operational difficulties. It was.
In Patent Document 3, a needle that can accommodate the entire blood collection needle and that has an engagement portion formed on the inner surface that engages with the blood collection needle base and prevents the blood collection needle from dropping off in a state in which the entire blood collection needle is accommodated. A cover invention is disclosed.
In order to form the engaging part (protrusion etc.) on the inner surface of the needle cover, the blood collection needle base must be formed so as to be able to get over the engaging part (protrusion etc.), so that the design is not always easy. .
Further, the invention does not describe any engagement structure with the blood collection tube holder.
本発明が解決しようとする問題点は、針カバーを採血管ホルダの奥深くまで挿入する形態であるため、操作上の難点がある点、針カバーは採血針の脱落を抑制できるが、採血管ホルダと接続できない点である。 The problem to be solved by the present invention is a form in which the needle cover is inserted deeply into the blood collection tube holder. Therefore, there is a problem in operation, and the needle cover can suppress the drop of the blood collection needle. It is a point that cannot be connected.
