Abstract
The utility model discloses a disposable needle for blood collection and transfusion. The disposable needle comprises a needle head and a needle handle, wherein the tail end of the needle handle is connected with a needle tube, butterfly wings are arranged on the two sides of the needle handle, fixing grooves are formed in the end portions of the butterfly wings on the two sides, the depth of each fixing groove is half of the length of each butterfly wing, protrusions are arranged on the two sides of the fixing grooves, transverse grooves are formed in the bottoms of the fixing grooves, and the positions, close to the needle handle, of the butterfly wings are made of a soft material easy to bend. Compared with the prior art, the fixing grooves are formed in the butterfly wings, so that the needle head can be conveniently restrained to a certain degree in the direction of the blood vessel, and the fixing effect is good. The disposable needle for blood collection and transfusion is simple in structure and convenient to operate, and various risks are reduced.
Description
Technical field
This utility model relates to a kind of disposable adopting
/The syringe needle of blood transfusion usefulness belongs to technical field of medical instruments.
Background technology
At present, Blood Transfusion Services or hospital blood sampling or when blood transfusion employed disposable wearing pricker generally thicker, mainly by syringe needle, consist of with needle handle and the needle tubing of the butterfly wing, syringe needle thrusts human vas during puncture, again butterfly wing docile is cemented at human body skin, take a blood sample or transfuse blood; Particularly when machine is adopted owing to adopting/transfusion speed is very fast, produce haemolysis and blood for fear of erythrocyte fragmentation and assemble and stop up syringe needle, thus use mostly be thicker syringe needle 16-17 number, adopt for making
/Blood transfusion is carried out smoothly, usually needs blood donation personnel to cooperate the action of repeatedly clenching fist, putting fist, finishes smoothly the time about 1-2 hour that approximately needs.Skid off from blood vessel if in this process, syringe needle occurs, in time do not press the site of puncture with cotton balls and stop blooding owing to have suddenly of occurring of situation, the risk of hemorrhage, blood contamination even air embolism can occur.
Summary of the invention
Technical problem to be solved in the utility model is the problem that exists for prior art, provide a kind of convenience fixing adopt/transfuse blood piercing needle.
For solving this technical problem, this utility model provides a kind of disposable adopting/transfuse blood and use syringe needle, comprises syringe needle and needle handle, the end of needle handle connects needle tubing, the both sides of needle handle are provided with the butterfly wing, are provided with holddown groove at the end position of the both sides butterfly wing, and the degree of depth of described holddown groove is 1/2 of the butterfly wing.
The both sides of described holddown groove are provided with projection.
The bottom of described holddown groove is provided with translot.
The butterfly wing is flexible flexible material near the position of needle handle.
Beneficial effect: this utility model compared with prior art, owing to being provided with holddown groove in butterfly alar part position, can give certain constraint with syringe needle in the direction along blood vessel easily, therefore have good fixed effect, and simple in structure, easy to operate, reduced the generation of various risks.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is this utility model butterfly wing embodiment one structural representation;
Fig. 3 is this utility model butterfly wing embodiment two structural representations.
Among the figure: 1 syringe needle, 2 needle handles, the 3 butterfly wings, 4 holddown grooves, 5 needle tubings, 6 projections, 7 translots.
The specific embodiment
Below in conjunction with drawings and Examples this utility model is done specific descriptions.
Figure 1 shows that structural representation of the present utility model.
This utility model comprises syringe needle 1 and needle handle 2, and the end of needle handle 2 connects needle tubing 5, and needle handle 2 both sides are provided with the butterfly wing 3.
End position at the both sides butterfly wing 3 is provided with holddown groove 4, and the degree of depth of described holddown groove 4 is 1/2 of the butterfly wing 3.
As embodiment one of the present utility model, the both sides of described holddown groove 4 are provided with protruding 6(as shown in Figure 2), projection 6 can prevent that adhesive plaster from deviating from.
As embodiment two of the present utility model, the bottom of described holddown groove 4 is provided with translot 7(as shown in Figure 3), translot 7 can make the adhesive plaster that passes keep smooth, makes sticking effect better.
For make the butterfly wing 3 can better docile on human body skin, be flexible flexible material at the butterfly wing 3 near the position of needle handles 2, perhaps slightly thinner than the thickness of the butterfly wing 3.
This utility model in use, at first syringe needle thrusts human vas, again with butterfly wing docile on human body skin, use adhesive plaster by two holddown grooves of the butterfly wing syringe needle to be sticked on the arm, for guaranteeing to stablize, paste the constantly large half cycle stickup of thorny arm, draw blood or transfuse blood.
This utility model compared with prior art, owing to being provided with holddown groove in butterfly alar part position, can give certain constraint with syringe needle in the direction along blood vessel easily, therefore have good fixed effect, and simple in structure, easy to operate, reduced the probability that various risks occur.
The above-mentioned embodiment of this utility model just illustrates, and is not only, all in this utility model scope or the change that is equal in the scope of the present utility model all surrounded by this utility model.
