Description

本発明は、透析、輸液、輸血、経管栄養、人工肺用回路等のコネクター等の接続部材を有し、かつ当該接続部材の固定具を有する医療用具の接続補助部材と、当該接続補助部材付き医療用具の改良に関する。例えば前記医療用具と体内留置用カテーテルまたは留置針等の接続補助部材として好適に使用することができる。   The present invention includes a connection auxiliary member for a medical device having a connection member such as a connector for dialysis, infusion, blood transfusion, tube feeding, artificial lung circuit and the like, and a fixing member for the connection member, and the connection auxiliary member The present invention relates to improvement of attached medical devices. For example, the medical device can be suitably used as a connection assisting member such as an indwelling catheter or an indwelling needle.

例えば特許文献１には、液体移送チューブに装着されたオス型接続部材とメス型接続部材を嵌合し、当該嵌合部の外周に、さらに固定部材を回動して強固に固定するようにした医療用具が記載されている。なお固定部材は一方の液体移送チューブに滑動自在に取り付けられている。しかしながら特許文献１に記載の医療用具では、固定部材が円筒形に形成され、また外周に突部が形成されているので、例えば患者の腕にテープを用いて固定する際、当着面積が小さく、固定状態が不安定である。このため固定部より、接続部材が外れたりずれたりして、稀であるが当該固定部より、液漏れや空気の混入等が生じることが懸念される。
更に突部が腕に当接するので患者に痛みと不快感を与えることが懸念される。また長時間の固定により腕の皮膚と前記突部に摩擦が生じ擦過傷を発生させることが懸念される。 For example, in Patent Document 1, a male connection member and a female connection member mounted on a liquid transfer tube are fitted, and a fixing member is further rotated and firmly fixed to the outer periphery of the fitting portion. A medical device is described. The fixing member is slidably attached to one of the liquid transfer tubes. However, in the medical device described in Patent Document 1, since the fixing member is formed in a cylindrical shape and the protrusion is formed on the outer periphery, for example, when fixing to the patient's arm using tape, the wearing area is small. The fixed state is unstable. For this reason, it is rare that the connecting member comes off or shifts from the fixed portion, but there is a concern that liquid leakage or air mixing may occur from the fixed portion.
Furthermore, since the protrusion comes into contact with the arm, there is a concern that pain and discomfort may be given to the patient. In addition, there is a concern that friction between the skin of the arm and the protrusions due to long-time fixation may cause scratches.

また特許文献２には、メス型ルアーコネクターの内腔部に接続可能なオス型ルアーテーパーを有し、かつ前記メス型ルアーコネクターの外周部に固定可能な固定手段を有し、当該固定手段に、前記メス型ルアーコネクターの外周部を圧迫固定可能な固定装置を配置することにより強固な接続部の固定を可能とした医療用コネクターが記載されている。そして当該医療用コネクターは、固定装置の底部を水平に形成することで患者に当着する際の違和感を軽減することができ、さらに前記底部に翼部を形成することにより、当着面積を広くし患者の腕に固定し易くすることができる旨が記載されている。しかしながら特許文献２に記載の医療用コネクターでは、固定装置の底部に形成した翼部が、障害となって、オス型コネクターとメス型コネクターとの着脱作業を困難にすることが懸念される。
実開昭６２−２４８３６号公報（第１図、第２図） 特開２００２−１５９５７９号公報（第１図〜第８図） Patent Document 2 also includes a male luer taper that can be connected to the inner cavity of the female luer connector, and a fixing means that can be fixed to the outer periphery of the female luer connector. A medical connector is described in which a fixing device capable of compressing and fixing the outer peripheral portion of the female luer connector can be arranged to fix a strong connection portion. The medical connector can reduce the uncomfortable feeling when wearing the patient by forming the bottom part of the fixing device horizontally, and further widening the wearing area by forming a wing part on the bottom part. It is described that it can be easily fixed to the patient's arm. However, in the medical connector described in Patent Document 2, there is a concern that the wing formed at the bottom of the fixing device becomes an obstacle and makes it difficult to attach and detach the male connector and the female connector.
Japanese Utility Model Publication No. 62-24836 (FIGS. 1 and 2) JP 2002-159579 A (FIGS. 1 to 8)

解決しようとする問題点は、患者の腕に固定する際に、固定状態が不安定である点、患者に痛みと不快感を与える点及び長時間の固定により腕の皮膚に擦過傷を発生しやすい点並びに着脱作業が困難な点である。   The problem to be solved is that when fixing to the patient's arm, the fixed state is unstable, pain and discomfort to the patient, and the skin of the arm is easily scratched due to long-time fixation It is a point and the point which is difficult to attach or detach.
