Abstract
The utility model provides a pressurized transfusion facility. The pressurized transfusion facility comprises a puncture needle, wherein an air inlet and a liquid outlet are formed in the puncture needle, the air inlet of the puncture needle is connected with an air inlet pipe and an air filter, the liquid outlet of the puncture needle is connected with a transfusion pipe, a murphy type dropper, a flow controller, a liquid filter and a vein needle. The pressurized transfusion facility is characterized in that the far end of the air inlet pipe is connected with an injector joint, and a one-way air valve is arranged between the injector joint and the air inlet of the puncture needle. The pressurized transfusion facility is reasonable in structural design and easy to use, can be used as a common transfusion facility and can also be used when pressurized transfusion is required to be carried out; and meanwhile the one-way air valve is adopted for preventing a high-pressure liquid in a liquid bottle from flowing out from the air inlet pipe, so that the probability that a liquid in the liquid bottle is polluted is reduced.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically, relates to a kind of pressurizing infusion set.
Background technology
In clinical transfusion, especially in critical patient's rescue process, often need some medicines of fast infusion, during as input mannitol, need a large amount of medicine of input within a short period of time.Traditional transfusion device is not provided with the pressure transfusion function, often needs the medical worker directly to inject air with syringe in liquid bottles from bottle stopper in clinical practice, increases the liquid bottles internal pressure, accelerates transfusion speed.But, this complex operation, repeated localised puncture causes easily that bottle stopper is airtight, and leakage sternly do not take place; And the forced air that injects like this can not get filtering, and causes liquid contamination easily, is serious medical hidden danger.
The utility model content
The purpose of this utility model is to overcome the weak point of above-mentioned conventional art, provide a kind of rational in infrastructure, can satisfy the pressurizing infusion set that opportunities for contamination was used, can not increased in pressurization or conventional transfusion simultaneously.
The purpose of this utility model reaches by following technical measures:
A kind of pressurizing infusion set, comprise puncture needle, puncture needle has air intake and liquid outlet, the air intake of puncture needle is connected with air inlet pipe and air filter, the liquid outlet of puncture needle is connected with tube for transfusion, Mo Feishi dropper, flow controller, liquid filter and intravenous needle, it is characterized in that: the far-end of described air inlet pipe is connected with syringe adapter, is provided with Non-return air valve between the air intake of described syringe adapter and puncture needle.Syringe adapter on the air inlet pipe allows to connect syringe and carries out artificial gas injection pressurization, and the liquid bottles inner air pressure is increased, and accelerates transfusion speed; Non-return air valve can avoid the highly pressurised liquid in the liquid bottles to flow out from air inlet pipe again simultaneously.
As a kind of concrete preferred version, described Non-return air valve is between syringe adapter and air filter.
As a kind of concrete preferred version, described Non-return air valve is between the air intake of air filter and puncture needle.
As a kind of improvement, described syringe adapter is provided with gas-pervious joint protective cover.The joint protective cover can adopt in its end micropore is set, and perhaps uses aseptic filter paper to make in its end, reaches gas-pervious purpose.Gas-pervious joint protective cover both can not protect syringe adapter not contaminated when normally not pressurizeing use, can take off at any time when the needs pressurization is used again, carried out pressurized operation.
Owing to adopted technique scheme, compared with prior art, the utility model has the advantages that:
This utility model reasonable in design, easy to use, can use as general infusion set, can carry out pressure transfusion again when needed and use; Simultaneously, this utility model adopts Non-return air valve to prevent that the highly pressurised liquid in the liquid bottles from flowing out from air inlet pipe, can reduce the chance of liquid contamination in the liquid bottles.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Accompanying drawing 1 is the structural representation of a kind of pressurizing infusion set of this utility model;
Accompanying drawing 2 is the structure for amplifying sketch maps at A place in the accompanying drawing 1.
The specific embodiment
Embodiment: as shown in Figures 1 and 2, a kind of pressurizing infusion set, comprise puncture needle 1, puncture needle 1 has air intake and liquid outlet, the air intake of puncture needle 1 is connected with air inlet pipe 2 and air filter 3, the liquid outlet of puncture needle 1 is connected with tube for transfusion 8, Mo Feishi dropper 9, flow controller 10, liquid filter 11 and intravenous needle 12, and the far-end of air inlet pipe 2 is connected with syringe adapter 7, is provided with Non-return air valve 4 between the air intake of syringe adapter 7 and puncture needle 1.Syringe adapter 7 on the air inlet pipe 2 allows to connect syringe and carries out artificial gas injection pressurization, and the liquid bottles inner air pressure is increased, and accelerates transfusion speed; Non-return air valve 4 can avoid the highly pressurised liquid in the liquid bottles to flow out from air inlet pipe 2 again simultaneously.
As shown in Figure 2, Non-return air valve 4 is between syringe adapter 7 and air filter 3.Certainly, Non-return air valve 4 also can be between the air intake of air filter 3 and puncture needle 1, and both effects are identical.
As shown in Figure 2, syringe adapter 7 is provided with gas-pervious joint protective cover 5.5 employings of joint protective cover are provided with micropore 6 in its end and reach gas-pervious purpose.Gas-pervious joint protective cover 5 both can not protect syringe adapter 7 not contaminated when normally not pressurizeing use, can take off at any time when the needs pressurization is used again, carried out pressurized operation.
