背景技术 Background technique
现有的留置针一般包括留置软管、留置针座、延长管座、连接于留置针座与延长管座之间的延长软管、装置于延长软管上的止液夹，而现有的止液夹一般包括夹座、一体装置于夹座上的夹片，夹座穿置于延长软管上，通过夹片与夹座的配合可将延长软管夹紧形成止液。但由于现有的止液夹在夹紧延长软管的过程中由于夹紧的延长软管在止液夹的夹片松开后会有一个回弹，使原夹紧的延长软管形成一个弹性反弹而导致血液回流到留置软管内，造成血液回流而形成血栓，影响留置针的使用性能。同时由于留置软管的尖端是开放的，随病人呼吸和心跳变化带来的压力波动也会出现回血以及血小板和凝血物质进入到留置软管内造成凝血堵管的现象，特别是由于止液夹活动地装置于延长管上，在输液完毕和止液后的过程中，止液夹容易在留置针座上摆动，导致延长软管内的液体产生虹吸作用而将血管内血液回吸到留置软管内，造成血液回流而形成血栓，严重影响留置针的使用时间，因此现有的留置针一般只能使用1-2天就因为血栓的形成而必须将留置针拔除，更换新的留置针。 Existing indwelling needles generally include an indwelling hose, an indwelling needle base, an extension tube base, an extension hose connected between the indwelling needle base and the extension tube base, and a liquid stop clip installed on the extension hose. The liquid stop clamp generally includes a clamp seat and a clip piece integrated on the clamp seat. The clamp seat is placed on the extension hose, and the extension hose can be clamped to form a liquid stop through the cooperation of the clip piece and the clamp seat. However, due to the fact that the existing liquid stop clamp will have a rebound after the clip of the liquid stop clamp is loosened in the process of clamping the extension hose, the original clamped extension hose will form a The elastic rebound causes the blood to flow back into the indwelling tube, causing the blood to flow back and form a thrombus, which affects the performance of the indwelling needle. At the same time, because the tip of the indwelling hose is open, pressure fluctuations caused by changes in the patient's breathing and heartbeat will also cause blood backflow and platelets and coagulation substances to enter the indwelling hose, causing coagulation to block the tube, especially due to the hemostatic clip Actively installed on the extension tube, during the process of completing the infusion and stopping the liquid, the liquid stop clip is easy to swing on the indwelling needle seat, causing the liquid in the extension tube to produce a siphon effect and suck the blood in the blood vessel back to the indwelling soft tube. In the tube, blood backflow causes thrombus to form, which seriously affects the use time of the indwelling needle. Therefore, the existing indwelling needle can only be used for 1-2 days, and the indwelling needle must be removed and replaced with a new one due to the formation of thrombus.
