Automatic infusion apparatus

Abstract

The invention discloses an automatic infusion apparatus, comprising a dynamic liquid supply mechanism, a liquid addition three-way pipe, a liquid stopping clamp, an upper conduit, an infusion three-way pipe, a dripping hopper, a lower conduit, a flow adjuster, a connection needle bed, an infusion needle tubule and a venous infusion needle, wherein the dynamic liquid supply mechanism is provided with an upper support pipe, a lower support pipe, a base and an elastic liquid storage sac, and the lower end part of the lower support pipe is fixedly connected with the base in a sealing way and communicated with a through hole of the base; the upper support pipe is movably sleeved on the lower support pipe; and the elastic liquid storage sac is arranged outside the upper support pipe and the lower support pipe, and the liquid addition three-way pipe is arranged between the dynamic liquid supply mechanism and the liquid stopping clamp. The lower part of the dripping hopper can be further provided with a selection infusion device, an upper cover, and a precision filter of a membrane filter mounting base. The selection infusion device is provided with a main infusion pipe, a slow infusion pipe and a liquid stopping pipe. The upper part of the main infusion pipe is provided with an air blocking slot, the upper cover is internally provided with a deflector and the filter mounting base canbe further provided with a deflector. Accordingly, infusion in a non-vertical state can be realized and blood return can be prevented.

Description

technical field [0001] The invention relates to an infusion device technology, in particular to an automatic infusion device. Background technique [0002] In the clinical treatment process, many patients often need to carry out transfusion, so as to treat diseases and rescue patients by the treatment means of transfusion. Thereby, infusion is an important technical measure of carrying out scientific treatment and patient's rescue, thus also makes need a large amount of use infusion set in clinical treatment process. [0003] In the prior art, the core of the infusion set is the dripping funnel. The infusion speed of the infusion set is observed through the dripping speed of the dripping funnel. Therefore, there must be air in the dripping funnel to observe the dripping speed of the dripping funnel, but if the air enters the human body through the catheter, serious medical accidents will occur, so When using any infusion set with a drip funnel for transfusion, the drip fun...

AI Technical Summary

Problems solved by technology

Since the dripping funnel needs to be kept vertical and high, and patients usually need to sit or lie in a fixed position during infusion and cannot move at will, if the patient needs to move, he must use himself or others to help lift the infusion bag or infusion bottle to accompany him. Therefore, it brings great inconvenience to patients and caregivers.

[0004] In the prior art, there are the following methods to solve the above problems: one method is to use an electric control pressure infusion device product, specifically to use a container to fix the dripping funnel vertically, this method is not only troublesome to use, but also requires supporting expensive equipment

Another method is to use an "analgesic pump" without a drip funnel. Although it can realize infusion in a non-vertical state, since there is no drip funnel, it is impossible to observe the drip speed and adjust the speed, so it can only infuse at a fixed speed, and it is limited to Used as a microinfusion solution, which greatly limits its use and is also expensive
