在图中，本实用新型止液夹包括本体1，所述本体1的一侧设有固定臂2，另一侧设有弹性臂3。所述固定臂2和弹性臂3上均设有容许输液管E穿过的输液管固定孔D。在使用本实用新型时，输液管E从所述固定臂2和弹性臂3上的输液管固定孔D穿过。所述固定臂2的自由端和弹性臂3的自由端在止液夹闭合时卡接；所述固定臂2的自由端还设有突出部K，当止液夹闭合时，所述弹性臂3的自由端卡设在所述突出部K下。 In the figure, the liquid stop clip of the present invention includes a body 1, a fixed arm 2 is provided on one side of the body 1, and an elastic arm 3 is provided on the other side. Both the fixing arm 2 and the elastic arm 3 are provided with an infusion tube fixing hole D allowing the infusion tube E to pass through. When using the utility model, the infusion tube E passes through the infusion tube fixing hole D on the fixed arm 2 and the elastic arm 3 . The free end of the fixed arm 2 and the free end of the elastic arm 3 are clamped when the liquid stop clip is closed; the free end of the fixed arm 2 is also provided with a protrusion K, and when the liquid stop clip is closed, the elastic arm The free end of 3 is clamped under the protruding part K.
所述本体1上设有第一本体锁紧部A1，所述弹性臂3对应第一本体锁紧部A1设有第一弹性臂锁紧部A2；所述本体1上还在第一本体锁紧部A1相连接处设有本体挤压排液部B1，所述弹性臂3对应本体挤压排液部B1设有弹性臂挤压排液部B2。 The body 1 is provided with a first body locking portion A1, and the elastic arm 3 is provided with a first elastic arm locking portion A2 corresponding to the first body locking portion A1; the body 1 is also provided with a first body lock A body extruding and draining part B1 is provided at the joint of the tightening part A1, and the elastic arm 3 is provided with an elastic arm extruding and draining part B2 corresponding to the body extruding and draining part B1.

本实用新型在打开止液夹的状态下，即所述固定臂2的自由端和弹性臂3的自由端并没有卡接，所述第一本体锁紧部A1和第一弹性臂锁紧部A2、所述本体挤压排液部B1和弹性臂挤压排液部B2、所述第二本体锁紧部C1和第二弹性臂锁紧部C2并不对输液管E进行挤压，这样，输液管E内的液体可以自由地在输液管E内流动。当本实用新型在关闭止液夹的状态下，即所述固定臂2的自由端和弹性臂3的自由端处于卡接状态下，所述第一本体锁紧部A1和第一弹性臂锁紧部A2、所述本体挤压排液部B1和弹性臂挤压排液部B2、所述第二本体锁紧部C1和第二弹性臂锁紧部C2抵靠设置并连续夹紧输液管E，这时，输液管E内的液体不能从夹紧点的一侧向另一侧流动，而且，所述本体挤压排液部B1和弹性臂挤压排液部B2相互挤压输液管E而产生一个输液正压，使输液管E内的液体向前推进，可防止血液回流到输液管E内和血液堵塞静脉留置针或注射针针头，从而避免形成血栓。 When the utility model is in the state of opening the liquid stop clamp, that is, the free end of the fixed arm 2 and the free end of the elastic arm 3 are not engaged, the locking part A1 of the first body and the locking part of the first elastic arm A2. The body squeezes the liquid discharge part B1 and the elastic arm squeezes the liquid discharge part B2, the second body locking part C1 and the second elastic arm locking part C2 do not squeeze the infusion tube E, thus, The liquid in the infusion tube E can freely flow in the infusion tube E. When the utility model is in the state of closing the liquid stop clamp, that is, the free end of the fixed arm 2 and the free end of the elastic arm 3 are in the clamping state, the first body locking part A1 and the first elastic arm lock The tightening part A2, the body squeezing and discharging part B1 and the elastic arm squeezing and discharging part B2, the second body locking part C1 and the second elastic arm locking part C2 are set against and continuously clamp the infusion tube E. At this time, the liquid in the infusion tube E cannot flow from one side of the clamping point to the other, and the body squeezes the liquid discharge part B1 and the elastic arm squeezes the liquid discharge part B2 to squeeze the infusion tube against each other E produces a positive pressure for infusion, so that the liquid in the infusion tube E is pushed forward, which can prevent blood from flowing back into the infusion tube E and blocking the venous indwelling needle or injection needle needle, thereby avoiding the formation of thrombus.
本实用新型之所以还在第一本体锁紧部A1相连接处设有本体挤压排液部B1，所述弹性臂2对应本体挤压排液部B1设有弹性臂挤压排液部B2，是当本实用新型在关闭止液夹的状态下，加强夹紧输液管E，将输液管E内的液体平衡挤压，使所述输液管E的夹紧点与人体输液部位之间有效产生一个输液正压。 The reason why the utility model is also provided with a body extruding liquid discharge part B1 at the joint of the first body locking part A1, and the elastic arm 2 is provided with an elastic arm extruding liquid discharge part B2 corresponding to the body extruding liquid discharge part B1 , when the utility model is in the state of closing the liquid-stop clamp, strengthen the clamping of the infusion tube E, and squeeze the liquid in the infusion tube E in balance, so that the clamping point of the infusion tube E and the infusion site of the human body are effectively Create a positive infusion pressure.
本实用新型之所以还在所述弹性臂挤压排液部B1一侧设有第二本体锁紧部C1，在所述弹性臂3对应于第二本体锁紧部C1设有第二弹性臂锁紧部C2，这除了其相互挤压输液管E而产生输液正压外，还是对第一本体锁紧部A1和第一弹性臂锁紧部A2、本体挤压排液部B1和弹性臂挤压排液部B2挤压输液管E可靠性的进一步提高：这由于第二本体锁紧部C1与第二弹性臂锁紧部C2还同时夹紧输液管E，即使弹性臂3的自由端被按压后回复到固定臂2自由端的突出部K下，输液管E内的液体也无法再倒流，从而又多了一重技术措施有效地确保输液管E输液正压的产生，避免出现任何负压的现象。 The utility model is also provided with a second body locking part C1 on the side of the elastic arm squeezing the liquid discharge part B1, and a second elastic arm is provided on the elastic arm 3 corresponding to the second body locking part C1 The locking part C2, in addition to squeezing the infusion tube E to generate positive pressure for infusion, is also the first body locking part A1 and the first elastic arm locking part A2, the body squeezing the liquid discharge part B1 and the elastic arm Squeeze the discharge part B2 to further improve the reliability of squeezing the infusion tube E: this is because the second body locking part C1 and the second elastic arm locking part C2 also clamp the infusion tube E at the same time, even if the free end of the elastic arm 3 After being pressed, it returns to the protruding part K of the free end of the fixed arm 2, and the liquid in the infusion tube E can no longer flow back, thus adding another technical measure to effectively ensure the positive pressure of the infusion tube E to avoid any negative pressure. The phenomenon.
应用本实用新型，能使输液管E实现真正意义上的输液正压。 By applying the utility model, the infusion tube E can realize positive pressure for transfusion in the real sense.
本实用新型的优先方案是：所述本体1、固定臂2和弹性臂3一体成型。 The preferred scheme of the present utility model is: the body 1, the fixed arm 2 and the elastic arm 3 are integrally formed.
以上所述的仅是本实用新型的优先实施方式。应当指出，对于本领域普通技术人员来说，在不脱离本实用新型原理的前提下，还可以作出若干变型和改进，这也视为属于本实用新型的保护范围。 What has been described above is only the preferred implementation of the present utility model. It should be pointed out that those skilled in the art can make several modifications and improvements without departing from the principle of the utility model, which are also considered to belong to the protection scope of the utility model.
