次に本発明のクランプ付翼付針の使用方法の一例について説明する。 Next will be described an example of how to use the winged needle clamp with the present invention.
[通常使用時] [Normal use]
図1(図2)の状態( 第1の使用位置;クランプ1が翼付針21のチューブ24に装着された状態、さらに詳述すれば、クランプ1の緊合突起部5と緊合溝部6が開いた状態にあり、翼付針21のチューブ24が、クランプ1のチューブ挿入孔9、10に挿入された状態)から、片手でクランプ1を把握し、同片手で、屈曲部4壁面を針22方向に押して、クランプ1を針22方向に前進させる。 Figure 1 (Fig. 2) in the state (first use position; the clamps 1 is attached to the tube 24 of the winged needle 21 and, more specifically,緊合projections 5 and緊合groove 6 of the clamp 1 in a state where the open tubes 24 of the winged needle 21 from the inserted state) to the tube insertion holes 9, 10 of the clamp 1, to grasp the clamp 1 with one hand, the same hand, the bent portion 4 wall press the needle 22 direction, to advance the clamp 1 to the needle 22 direction. クランプ1の前進中、チューブ24は側壁24にガイドされているので、針22を前方部の先端から後方部の後端に至るまで全て、確実にクランプ1内(封止部2と底部3の対向する上壁面(底面部)と下壁面(天面部)の間の空間内)に収納することができる。 During advancement of the clamp 1, the tube 24 is guided by the side walls 24, all needle 22 from the distal end of the front portion up to the rear end of the rear portion, reliably within the clamp 1 (the sealing portion 2 and the bottom 3 it can be housed in the upper wall surface facing the space between the (bottom portion) and the lower wall surface (top surface)).
翼23が屈曲部4の壁面の当接するまで、クランプ1を前進させ、針22の鋭利な先端をクランプ1内(封止部2と底部3の対向する上壁面(底面部)と下壁面(天面部)の間の空間内)に収納し、緊合突起部5を緊合溝部6方向に押し下げて、これらを緊合する。 Until the wing 23 abuts against the wall surface of the bent portion 4, to advance the clamp 1, clamping within 1 a sharp tip of the needle 22 (on the opposite of the sealing portion 2 and the bottom 3 walls (bottom portion) and the lower wall surface ( housed in a space) between the top surface portion), depress the 緊合 projections 5 in 緊合 groove 6 direction, these are 緊合. (第2の使用位置) (Second use position)
第2の使用位置では、チューブ24は、封止部2の第2挟持部T22と底部3の第2挟持部T32とにより挟持され、針22も封止部2の第1挟持部T21と、底部3の第1挟持部T31とにより挟持されており、緊合突起部5と緊合溝部6は、容易に開かないので、針22の鋭利な先端は、外に露出することはない。 In the second use position, the tube 24 is held between the second clamping portion T32 of the second holding portion T22 and the bottom 3 of the sealing portion 2, a first clamping portion T21 needle 22 of the sealing portion 2, the first clamping portion T31 of the bottom 3 and are held by, the 緊合 projections 5 and 緊合 groove 6 is not easily opened, sharp tip of the needle 22 is not exposed to the outside. これにより、針の廃棄作業を安全に行える。 As a result, the safe to the needle of the disposal work. また操作も片手で行えるので、操作性が良い。 Further, since the operation is also carried out with one hand, a good operability.

[緊急使用時] [Emergency use at the time]
図9に例示するように体外循環回路31の動脈側回路32と静脈側回路33に、コネクタ25、35を介して、クランプ1をチューブ24の途中に装着した翼付針21を接続した状態(体外循環時)から、地震等の天災地変がおきた場合、図5(図6)に例示するように、クランプ1を閉じる(緊合突起部5を緊合溝部6方向に押し下げて、これらを緊合する)。 The artery side circuit 32 and the vein side circuit 33 of the extracorporeal circuit 31 as illustrated in FIG. 9, a state in which through the connectors 25 and 35, and the clamp 1 connects the winged needle 21 mounted in the middle of the tube 24 ( from the time of extracorporeal circulation), when every other natural disasters such as an earthquake, as illustrated in FIG. 5 (6), press down the clamp 1 close (緊合 tip 5 to 緊合 groove 6 direction, these to 緊合).
チューブ24は、 封止部2の第1挟持部T21と、底部3の第1挟持部T31、及び封止部2の第2挟持部T22と底部3の第2挟持部T32とにより二箇所で挟持され、緊合突起部5と緊合溝部6は、容易に開かないので、確実に体外循環をクランプ1で中断して、コネクタ25、35とクランプ1間のチューブ24を切断して、速やかに避難することができる。 Tube 24 includes a first clamping portion T21 of the sealing portion 2, the first clamping portion T31 of the bottom 3, and by a second clamping portion T32 of the second holding portion T22 and the bottom 3 of the sealing portion 2 at two points is sandwiched, 緊合 projections 5 and 緊合 groove 6, does not easily open, reliably interrupt the extracorporeal circulation in the clamp 1, by cutting the tube 24 between the connector 25 and 35 and the clamp 1, promptly it is possible to evacuate to.
