CN2668147Y - Oxygen therapy filte with buffer air bag - Google Patents

Abstract

The utility model provides an oxygen therapy filter with buffering air bag. The filter body is a cavity pipe structure. A filter screen is provided inside the filter body, and the front end of filter body is a needle head connecting pipe, and the tail of the filter body is a catheter connecting port. The utility model is characterized in that the cavity pipe of the filter body is still provided with a by-pass branch pipe, and the by-pass branch pipe is connected with an elastic buffering air bag. The oxygen therapy filter adopts the structure of buffering air bag. As a result, the superfluous gas in the inflating bottle can be introduced to the buffering air bag through the by-pass branch pipe, and the pressure inside the infusion bottle is keep in consistent balance. The utility model can avoid the phenomenon that the infusion bottle expands and explodes because the inflating quantity is too much, and the utility model can also make the oxygenating transfusion more convenient, more reliable and safer.

Description

The oxygen therapy filter that has buffer air bag

Technical field:

This utility model is to the improvement of existing oxygen therapy filter, and a kind of oxygen therapy filter that has buffer air bag is provided, and belongs to the transfusion technical field of medical instruments.

Background technology:

At present, the transfusion gas filling bottle is by between the conduit connection and gas filling bottle and infusion bottle that has syringe needle and a filter, oxygen in the gas filling bottle is directly entered in the infusion bottle by conduit, though it is should the oxygen therapy mode simple and convenient, but, often owing to misoperation, make excessive gas enter into infusion bottle during use owing to be high pressure oxygen in the gas filling bottle, cause infusion bottle drum plug or transfusion bag explosion, bring very big trouble to clinical treatment.

Summary of the invention:

This utility model provides a kind of oxygen therapy filter that has buffer air bag, has solved oxygenation transfusion excess pressure oxygen and has directly entered the drum plug explosion problem that infusion bottle causes.

Technical solution of the present utility model is as follows: filter body is the cavity channel structure, in be provided with drainage screen, front end is that syringe needle is taken over, afterbody is the conduit connector, it is characterized in that: also be provided with bypass branch on the cavity channel of body, bypass branch is fixedlyed connected with the elastic buffer air bag.

This utility model in use, when the gas output of gas filling bottle and the medicine liquid droplet of infusion bottle speed was consistent, buffer air bag was an original state, when the gas output of gas filling bottle is excessive, unnecessary gas enters the elastic buffer air bag, alleviates the pressure of the inside of a bottle of infusion bottle, keeps the steady of transfusion.

Good effect of the present utility model is: adopt filter to adopt the buffer air bag structure, excess air in the gas filling bottle can be imported in the buffer air bag by bypass branch, pressure in the formula infusion bottle remains consistent balance, avoided because aeration quantity is excessive, cause infusion bottle drum plug and explosion phenomenon to take place, make the oxygenation transfusion convenient safe and reliable.

Description of drawings:

Fig. 1 is this utility model structure principle chart.

The specific embodiment:

According to shown in Figure 1, the inside of filter body 5 is cavity channel 3 structures, the outlet of pipeline 3 is provided with drainage screen 4, front end is that syringe needle takes over 2, can connect syringe needle 1, afterbody is a conduit connector 8, and the cavity channel 3 of body 5 is provided with bypass branch 6, and bypass branch 6 is fixedlyed connected with elastic buffer air bag 7.

Claims (1)

1, a kind of oxygen therapy filter that has buffer air bag, filter body is the cavity channel structure, in be provided with drainage screen, front end is that syringe needle is taken over, afterbody is the conduit connector, it is characterized in that: also be provided with bypass branch on the cavity channel of body, bypass branch is fixedlyed connected with the elastic buffer air bag.
