Abstract

The utility model provides a fluid infusion pressure device having the rapid fluid infusion. One end of the three-way pipe is connected with a one-way air inlet valve, an air inlet pipe and a filter, another end of the three-way pipe is connected with an air outlet pipe, a one-way air outlet valve and a needle, and the third end of the three-way pipe is connected with a syringe. While in use, the needle is inserted into a big fluid bottle, and the tip slope of the needle is higher than the fluid level, and then the pintle of the syringe is pumped; the gas enters into the syringe through the filter, the one-way air inlet valve and the air inlet pipe; the syringe is impelled, and then the gas enters onto the big fluid level through the one-way air outlet valve, the air outlet pipe and the needle to generate the pressure to act the function on the fluid to achieve the purpose of accelerating the fluid infusion via a venous fluid infusion device.

Description

Quick transfusion prelum

Affiliated technical field

This utility model relates to a kind of medical apparatus and instruments, specifically a kind of quick transfusion prelum.

Background technology

As everyone knows, at present in clinical vein is infused fast, with be that disposable syringe and vascular forceps are finished, method is earlier with a certain amount of unfiltered air of syringe pump, be injected in the big liquid by the transfusion device air inlet pipe, liquid in bottle, it is above and produce certain pressure to rise to liquid level, reaches the purpose of quick transfusion.Because the bottleneck contact pin of transfusion device is shorter, below liquid level, so when the gas in the syringe was injected in the liquid bottles, the gas of filtered rose by liquid and easily causes liquid contamination, simultaneously must clamp air inlet pipe with vascular forceps immediately, in case liquid countercurrent carries out, therefore so repeatedly, there is following shortcoming: 1, inject the intravital gas filtered of big liquid, easily cause liquid contamination.2, complex operation must 2 people be finished inefficiency.3, repeatable operation easily causes liquid countercurrent, the waste medicinal liquid.

Summary of the invention

In order to overcome the deficiencies in the prior art, this utility model provides a kind of quick transfusion prelum, and this prelum of infusing fast can be simplified the pressurized operation process, reduces the pollution of big liquid in the pressure process to greatest extent, alleviate medical workers, stop the medicinal liquid adverse current.

The technical scheme that its technical problem that solves this utility model adopts is: at a termination breather cheek valve of tee T, air inlet pipe and air filter, one termination syringe, the unidirectional air outlet valve of one termination, escape pipe and syringe needle, the long 10-20 of syringe needle centimetre, during use syringe needle is inserted in the big liquid bottles, the needle tip inclined-plane exceeds liquid level, pulling syringe pintle, at this moment unidirectional air outlet valve cuts out, and gas then passes through air filter, air inlet pipe and breather cheek valve enter in the syringe, then pushing syringe pintle forward, at this moment, breather cheek valve is closed, and gas then passes through tee T, unidirectional air outlet valve, escape pipe and syringe needle enter more than the big liquid levels, produce pressure, act on liquid.

The new beneficial effect of this practicality is: gas has reduced the pollution of big liquid in the pressure process to greatest extent through the filtration of filter, has alleviated medical workers, has stopped the medicinal liquid adverse current.
