Abstract
The utility model relates to a novel transfusion device, belonging to the technical field of a medical apparatus. The technical proposal is as follows: the transfusion device comprises a plastic needle head, a transfusion pipe, a Murphy dropper, a slide switch and a puncture needle head. The novel transfusion device is characterized in that an air-returning needle tube is fixedly arranged at the lateral side of the plastic needle head, and a unidirectional valve is arranged in the air-returning needle tube. The novel transfusion device has the advantages of simple structure and convenient use; when transfusion is made for a patient, medical liquid can not flow out from the air-returning tube, thereby the waste of the medical liquid is avoided.
Description
Technical field:
This utility model belongs to the medical instruments technical field, is a kind of novel transfusion device specifically.
Background technology:
At present, the return-air when giving patient infusion in the infusion bottle relies on the muffler of transfusion device to carry out, and muffler one end and the plastic spike of existing transfusion device connect together, the other end is exposed outside, a little more than bottleneck, like this when transfusion, medicinal liquid is easy to flow out in muffler, causes liquid waste.
Summary of the invention:
The purpose of this utility model provides a kind of when giving patient infusion, and medicinal liquid can the effusive novel transfusion device of air self-returning pipe.
The technical solution of the utility model is: comprise plastic spike, tube for transfusion, Murphy's burette, slide switch and piercing needle, it is characterized in that being fixed with the return-air needle tubing in the plastic spike side, be provided with one-way valve in the return-air needle tubing.
The beneficial effects of the utility model are: this utility model is simple in structure, and is easy to use, and when giving patient infusion, medicinal liquid can not go out by the air self-returning pipe flow, has avoided the waste of medicinal liquid.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
Among the figure 1, plastic spike, 2, tube for transfusion, 3, Murphy's burette, 4, slide switch, 5, piercing needle, 6, the return-air needle tubing, 7, one-way valve.
The specific embodiment:
Comprise plastic spike 1, tube for transfusion 2, Murphy's burette 3, slide switch 4 and piercing needle 5, it is characterized in that being fixed with return-air needle tubing 6, be provided with one-way valve 7 in the return-air needle tubing 6 in plastic spike 1 side.When giving patient infusion, plastic spike 1 is inserted in the infusion bottle together with the return-air needle tubing, negative pressure increases in the infusion bottle, and one-way valve 7 is opened, and air can enter in the infusion bottle.
