Description
技术领域technical field
本实用新型涉及一种采血针，尤其涉及一种用于内分泌试验的采血针。The utility model relates to a blood collection needle, in particular to a blood collection needle used for endocrine tests.
背景技术Background technique
内分泌试验通常需要在0-4小时内多次采血进行试验。现有的采血装置多为通用型才采血装置，通常是用注射器抽完血向真空采血管打，这时，需要把采血管帽，不能有效利用真空采血管负压采血的作用；需要的采血量较多时，通常需要两人协调操作，一人负责抽血，一人负责向真空采血管中打血，配合较慢时甚至会出现凝血现象，即血打进真空采血管后凝结成块，影响试验。另外，向真空采血管中打血时有时还会不小心会把血滴到外面，污染环境；有时会滴到护士手上，十分不安全。Endocrine tests usually require multiple blood draws over a period of 0-4 hours for the test. Most of the existing blood collection devices are general-purpose blood collection devices. Usually, the blood is drawn into the vacuum blood collection tube with a syringe. When the amount is large, usually two people are required to coordinate the operation, one is responsible for drawing blood, and the other is responsible for pumping blood into the vacuum blood collection tube. When the cooperation is slow, coagulation may even occur, that is, the blood coagulates into blocks after being injected into the vacuum blood collection tube, which affects the test. . In addition, when blood is pumped into the vacuum blood collection tube, sometimes the blood will drip outside accidentally, polluting the environment; sometimes it will drip onto the hands of the nurse, which is very unsafe.

优选地，所述真空采血针的外围设置筒形有护套。所述护套通过螺纹方式结合在所述真空采血针的外围，或者所述护套通过卡持方式结合在所述真空采血针的外围；或者所述护套通与所述真空采血针形成为一体。Preferably, a cylindrical sheath is provided on the periphery of the vacuum blood collection needle. The sheath is combined with the outer periphery of the vacuum blood collection needle by threading, or the sheath is combined with the outer periphery of the vacuum blood collection needle by clamping; or the sheath is formed with the vacuum blood collection needle as One.
优选地，所述头皮针、三通阀、真空采血针为分立构件，通过插接方式结合在一起；或者，所述头皮针、三通阀、真空采血针一体形成。Preferably, the scalp needle, the three-way valve, and the vacuum blood collection needle are discrete components, which are connected together by plugging; or, the scalp needle, the three-way valve, and the vacuum blood collection needle are integrally formed.
由于本实用新型的用于内分泌试验的采血针采用了三通阀以及真空采血针，可以不拆除真空采血管的密封的情况下反复使用真空采血管，效率十分高，可以在算时间内采集多管血液样本，且不会造成凝血现象的发生；另外，由于本实用新型的用于内分泌试验的采血针采用三通阀，可以在输液时选通输液瓶而在采血时选通真空采血针，使用起来十分灵活。Because the blood collection needle used for endocrine test of the utility model adopts a three-way valve and a vacuum blood collection needle, the vacuum blood collection tube can be used repeatedly without removing the seal of the vacuum blood collection tube, the efficiency is very high, and multiple blood collection can be collected within a calculation time. tube blood samples, and will not cause coagulation; in addition, because the blood collection needle used for endocrine test of the utility model adopts a three-way valve, the infusion bottle can be selected during infusion and the vacuum blood collection needle can be selected during blood collection. It is very flexible to use.
