Description

A kind of disposable pressue device accelerating transfusion speed

Technical field

This utility model relates to medical instruments field, especially a kind of disposable pressue device accelerating transfusion speed.

Background technology

In clinical, infusion is one of a lot of disease means of effective treatment; Namely venous transfusion connects a transfusion device with infusion bottle lower end, needs the speed controlling transfusion, reach the object of disease therapy according to the difference of patient.But some patient has the client need quiet fast of the patient of serious dehydration and some needs quiet mannitol, and the transfusion exhaustor that we use at present can not pressurize, and liquid droping speed is slow, the requirement of quick dropping liquid of can not satisfying the demand.

In view of the foregoing, the structure of existing transfusion device needs to improve.

Utility model content

The purpose of this utility model is to overcome deficiency of the prior art, and provide a kind of disposable pressue device accelerating transfusion speed, pressure process is safe and reliable, can press from both sides by closing switch in time after pressurization, avoid transfusion pressure of the inside of a bottle too high, liquid is excessive from exhaustor, and this utility model is suitable for needing the patient of quick dropping liquid to use, ensure transfusion speed, control transfusion speed and be in quick dropping liquid state all the time, structure is simple, easy to operate, production cost is low, and result of use is good.

This utility model to achieve these goals, adopt following technical scheme: a kind of disposable pressue device accelerating transfusion speed, be by: trachea, syringe needle, air vent, switch folder, air filter, cavity, filter membrane, transitional connection pipe, prelum are formed; Trachea front end arranges syringe needle, rear end arranges air filter, trachea is arranged switch folder, described syringe needle end arranges air vent, in described air filter, cavity is set, arrange filter membrane in cavity, described filter membrane adopts ionic membrane, arranges transitional connection pipe between the described air filter other end and the interface of prelum.

Described transitional connection pipe adopts resilient plastic tube, leather hose, rubber tube or silica gel tube one wherein.

Described prelum adopts ordinary syringe or pressurised airbag.

Using method: this utility model can as ordinary venous infuse exhaustor use, also can to pressurize use, when using as ordinary venous transfusion exhaustor, switch folder on trachea is in smooth open state, air enters transitional connection pipe, air filter, trachea and syringe needle successively, enter infusion bottle from the air vent of syringe needle, the dropping liquid in tube for transfusion is normal speed.

When pressurization uses, syringe needle is inserted in infusion bottle by bottle cap, switch folder on trachea keeps smooth open state, after prelum gathers air, the interface of prelum inserts transitional connection pipe, transitional connection pipe adopts resilient plastic tube, leather hose, rubber tube or silica gel tube one wherein, the mouth of pipe size of transitional connection pipe and the interface size of prelum basically identical, enable the interface quick insertion transitional connection pipe of prelum, open the switch folder on trachea, the air that extruding prelum makes it gather passes through transitional connection pipe successively, air filter, trachea and syringe needle, infusion bottle is entered from the air vent of syringe needle, after air enters the cavity in air filter, filter membrane adopts ionic membrane to the dust in air, antibacterial, material and impurity effectively filter, pitch of holes and the pore size of filter membrane are even, not yieldingly to come off, low to drug adsorption, free of contamination air enters infusion bottle, play the effect that infusion bottle is pressurizeed, after pressurization, quick closedown switch presss from both sides, the liquid in infusion bottle is avoided to flow out along trachea, prelum is used once to pressurize or repeatedly pressurize, gas pressure in infusion bottle is increased, when liquid droping speed in tube for transfusion reaches the requirement of quick dropping liquid, stop continuing pressurization, along with the liquid in infusion bottle oozes fast, gas pressure in infusion bottle diminishes gradually, and the liquid in infusion bottle oozes and slows, when the liquid droping speed in tube for transfusion is less than the speed of quick dropping liquid, circulate by above operating procedure, to infusion bottle pressurized control liquid droping speed.

The beneficial effects of the utility model are: prelum adopts ordinary syringe or pressurised airbag, or there is other device of identical pressurization principle, pressure is applied in infusion bottle, filter membrane in air filter adopts ionic membrane to the dust in air, antibacterial, material and impurity effectively filter, air filter can adopt other air filter with same air work principle of filter, pressure process is safe and reliable, can press from both sides by closing switch in time after pressurization, avoid transfusion pressure of the inside of a bottle too high, liquid is excessive from exhaustor, not only wasted medicinal liquid but also easily the contaminated liquid even hands of staff, the liquid droping speed of general infusion set is slower, this utility model can make liquid droping speed reach 100-300 to drip/point, be suitable for needing the patient of quick dropping liquid to use, ensure transfusion speed, control transfusion speed and be in quick dropping liquid state all the time, this utility model structure is simple, easy to operate, production cost is low, result of use is good, be applicable to popularity to use.
