Abstract

The utility model relates to a negative pressure transfusion device which comprises a transfusion bottle needle 10 of a traditional transfusion device, an exhaust pipe 2, a drip kettle 4, a medicine feeding port 3, a water stopping device 6 and a needle 7, wherein the components are orderly communicated by a liquid pipe 5. In addition, a negative pressure ball 8 and a water stopping device 9 are orderly added between the water stopping device 6 and the needle 7, and the negative pressure ball 8, the water stopping device 9, the water stopping device 6 and the needle 7 are communicated by the liquid pipe 5. The utility model utilizes the negative pressure ball 8 to make the lower part of the liquid pipe 5 form negative pressure and make blood return of the liquid pipe sensitive, so the successful rate of the venipuncture for children can be increased, and the pain of the patient children can be reduced. The utility model has the advantages of simple structure, low cost and convenient operation.

Description

The negative pressure transfusion device

This utility model relates to medical apparatus and instruments, especially a kind of negative pressure transfusion device.

Venous transfusion is one of therapy commonly used in clinical.Transfusion device at present commonly used mainly by one drip kettle, water ends and syringe needle, exhaustor are connected and composed by the liquid pipe.Drip on the kettle with dosing mouth.During venipuncture by whether there being blood back to judge whether intravasation of syringe needle in the liquid pipe.Children's is because vein is tiny, and intravenous forces down or dehydration, blood viscosity thicken, so though syringe needle intravasation when puncturing does not sometimes have blood back, cause and think puncture failure by mistake and puncture once more, increases the unnecessary misery of infant.

The purpose of this utility model is the problem that exists at present transfusion device, provide a kind of easy when judging infantile infusion syringe needle whether penetrate the negative pressure transfusion device of blood vessel.

This utility model is achieved in that the negative pressure transfusion device comprises that infusion bottle syringe needle, exhaustor, a kettle, the water of traditional infusion device end, syringe needle, is communicated with the liquid pipe successively.In addition, water end and syringe needle between also establish a negative pressure ball successively and a water ends, and be connected with the liquid pipe.

During use, the infusion bottle syringe needle is inserted infusion bottle, open upper and lower two water and only do conventional aerofluxus, and a kettle partly is full of.Dripping liquid pipe under the kettle, negative pressure ball all should full of liquid, no bubble.Close then and only close water.Left hand extruding negative pressure ball makes it to become flat, and the right hand is closed down water and ended.Routine is carried out venipuncture, when syringe needle thrusts subcutaneously, unclamps promptly down that water ends, and makes the bottom of liquid pipe form negative pressure, if syringe needle thrusts vein, visible blood-flow in the liquid pipe shows and punctures successfully, unclamps water and only can infuse.

The utility model has the advantages that utilizing negative pressure ball to make forms negative pressure in the liquid pipe, increase the pressure differential in vein and the liquid pipe, make liquid pipe blood back sensitivity, avoid because of child vein pressure little, but do not have the blood back phenomenon though syringe needle has thrust vein, puncture success rate is improved, avoid the unnecessary misery of infant.Negative pressure transfusion device simple structure, cost is low, and is easy to operate.

Fig. 1 is traditional transfusion device;

Fig. 2 is the negative pressure transfusion device.

Below in conjunction with accompanying drawing this utility model is done an into little explanation:

As shown in Figure 2, the negative pressure transfusion device comprises infusion bottle syringe needle 10 in the traditional infusion device, exhaustor 2, drips kettle 4, dosing mouth 3, water end 6, syringe needle 7, and is communicated with by liquid pipe 5 successively.In addition, water end 6 with syringe needle 7 between add negative pressure ball 8 and water only 9 and be communicated with successively by liquid pipe 5.Negative pressure ball 8 is a hollow projectile cartridge gonosome, long 1.5CM, diameter 1CM.

Claims

1, a kind of negative pressure transfusion device comprises the infusion bottle syringe needle of traditional infusion device, exhaustor, drips that kettle, water end, syringe needle, is communicated with the liquid pipe successively, it is characterized in that water end and syringe needle between also be provided with a negative pressure ball successively and a water ends, and be communicated with the liquid pipe.
