技术背景technical background
本发明涉及一种输液器，特别涉及一种带有自动换液的输液器。The invention relates to an infusion set, in particular to an infusion set with automatic liquid change.
背景技术Background technique
输液器是十分常见的医疗器械，主要用于建立输液瓶或输液袋等医药容器与静脉之间的药液通道。An infusion set is a very common medical device, mainly used to establish a liquid medicine channel between a medical container such as an infusion bottle or an infusion bag and a vein.
现有的输液器在使用时，需要通过人工观察药液是否输送完毕，以及时通知护理人员进行换药、拔针等操作，输液过程中如果患者睡着未及时发现药液输送完毕，未能及时换药，非常容易造成气体进入静脉、血液回流等医疗事故。When the existing infusion sets are in use, it is necessary to manually observe whether the liquid medicine has been delivered, and to notify the nursing staff in time to perform operations such as changing the dressing and pulling out the needle. Changing the dressing in time can easily cause medical accidents such as gas entering the vein and blood backflow.

In addition to the through hole in the middle, the lower plate surface also has the same number of through holes on the axis and the upper plate surface. The axis of the through hole on the lower plate is on the same axis as the axis of the through hole on the upper plate, and the diameter of the through hole on the lower plate is larger than the outer diameter of the mouth of the medicine bottle but smaller than that of the medicine bottle. The outer diameter of the bottle body. When passing the mouth end of the medicine bottle through the through hole on the upper plate and the through hole on the lower plate in turn, make sure that the mouth of the medicine bottle passes through the through hole on the lower plate while the bottom of the medicine bottle passes through the through hole on the lower plate. Still in the through hole on the upper surface.
所述夹子4为可拆卸的夹子4，并且也可以手动去控制夹子4的打开和闭合。防止液位传感器1或夹子4用久了不灵敏，而造成误判，滴液错误，影响病人健康。The clip 4 is a detachable clip 4, and the opening and closing of the clip 4 can also be manually controlled. Prevent the liquid level sensor 1 or clip 4 from being insensitive after a long period of use, causing misjudgment, wrong dripping, and affecting the health of patients.
本发明的有益效果是可以实现自动换液，解决了一次一次换液的复杂度,保证输液的精确性、可靠性 ,提高患者静脉输液的安全性。The beneficial effect of the present invention is that it can realize automatic liquid change, solve the complexity of changing liquid one by one, ensure the accuracy and reliability of infusion, and improve the safety of patients' intravenous infusion.
