Abstract
The utility model relates to an infusion set, which is characterized in that: an air sac is arranged in a liquid dropping tube. When in use, the air sac is floating on the liquid, after the injecting of the medicine liquid is finished, the air sac falls into the bottom of liquid dropping tube, the opening of a lower connection tube is sealed, the air being insulated on the liquid dropping tube can be realized, the safety of the injection can be ensured. The infusion set has rationale design, simple structure and convenient use, which reduces the labor intensity of the staff.
Description
Technical field
This utility model relates to and a kind of medicine is imported intravital apparatus, exactly is transfusion device.
Background technology
Known disposable transfusion device is a kind of medical apparatus and instruments of using always, and is easy to use, and is difficult for causing cross infection.But the weak point of its existence is that patient, family members and medical personnel are usually on tenterhooks for nurse transfusion, and after being in fear of liquid and being totally lost, gas can enter the human vein pipe.The consequence that gas enters the human vein pipe is very serious, gently then causes local edema, and is heavy then cause the vein blood vessel thromboembolism so that dead.Syringe needle is promptly pulled out under caregiver's majority situation that liquid is not totally lost as yet fully in medicine bottle in using in the historical facts or anecdotes border, stops transfusion; This practice had both caused liquid waste, influenced medical effect again.
Summary of the invention
In order to guarantee the safety of infusing, alleviate caregiver's worry, prevent that gas from entering the venous patient pipe, existing syringe is improved.
Concrete improvement project is as follows:
Transfusion device with air bag comprises input pipe, liquid dropping mechanism, drop regulator, air inlet pipe and syringe; Described liquid dropping mechanism comprises minim pipette, goes up connection tube and following connection tube, it is characterized in that: be provided with an air bag ball in minim pipette.
The air bag ball adopts latex material to be made into spheroid, charges into gas and get final product in spheroid.
The mouth of pipe that described connection tube down is positioned at minim pipette is not higher than minim pipette bottom neck.
By this improvement, this utility model in use, the air bag ball floats on the liquid upper surface, after medicinal liquid was totally lost, the air bag ball fell into minim pipette bottom, the mouth of pipe of connection tube is sealed down, realizes air is completely cut off on minim pipette top, has guaranteed the safety of transfusion.
This utility model is reasonable in design, and is simple in structure, easy to use, alleviated staff's labor intensity.
Description of drawings
Fig. 1 is this utility model structural representation,
Fig. 2 is this utility model user mode sketch map.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
This transfusion device comprises input pipe 1, liquid dropping mechanism, drop regulator, air inlet pipe and syringe.Described liquid dropping mechanism comprises minim pipette 2, goes up connection tube 3 and following connection tube 4, and an air bag ball 5 is housed in minim pipette 2, sees Fig. 1.And should guarantee down that the mouth of pipe that connection tube 4 is positioned at minim pipette 2 is not higher than minim pipette 2 bottom necks when installing.
During use, air bag ball 5 floats on liquid level under the liquid buoyancy effect, see Fig. 2, when liquid level drops to the neck place, lower end of minim pipette 2, air bag ball 5 will descend the mouth of pipe of connection tube 4 to seal, and air is completely cut off on minim pipette 2 tops, realize preventing air admission human vein pipe, guaranteed transfusion safety.
Claims (2)
1, the transfusion device that has air bag comprises input pipe, liquid dropping mechanism, drop regulator, air inlet pipe and syringe; Described liquid dropping mechanism comprises minim pipette, goes up connection tube and following connection tube, it is characterized in that: be provided with an air bag ball in minim pipette.
2, the transfusion device with air bag according to claim 1 is characterized in that: the mouth of pipe that described connection tube down is positioned at minim pipette is not higher than minim pipette bottom neck.
