Abstract

The utility model relates to an injection hemostix which is medical equipment combines the injection and the blood sampling. The utility model has the essential structure that the utility model is provided with a needle cylinder, a needle, a push rod, a piston, the needle socket at the front end of the needle cylinder is provided with a crossette, and a notch, the crossette is provided with a connector, the front end of the needle cylinder is connected with a plug lid, the inner wall of rear of the needle cylinder is provided with grooves, a taper hole is arranged in the plug lid, a boss is arranged at the orifice of the plug lid, and is matched with the notch on the needle socket. The utility model can be used as an ordinary disposable injector, and can be used as a disposable hemostix. The utility model has the advantages of convenient operation, and no cross infection. When the blood sampling is carried out, the red blood cell hemolysis is eliminated, and the blood is prevented from spilling from the needle cylinder.

Description

Injection hemostix

This utility model injection hemostix is the medical apparatus and instruments that a kind of injection combines with blood sampling.

General syringe is not store blood chemical examination function at present, and necessary injecting tube increases blood sampling person's route of infection after the blood sampling, in addition, send the blood of testing also contaminated easily, causes result of laboratory test error to occur.It is after adopting the push rod of syringe to do test tube (push rod hollow) blood sampling that a kind of test tube one hemostix is arranged, push rod is inverted do storage blood test tube, this hemostix causes negative pressure to make erythrocyte hemolysis in blood collection procedure easily, destroy erythrocyte and cause result of laboratory test error to occur, and the blood drawing amount does not reach requirement.This hemostix technology manufacturing requires high, complex process, manufacturing cost height.

The purpose of this utility model provides a kind ofly injects blood sampling and is the injection hemostix of one, on the syringe rear inside wall groove is arranged, have brace on the syringe front end syringe needle socket and be connected with gag, simple in structure, safe in utilization, reliable, be not easy to pollute, haemolysis.

This utility model injection hemostix takes following mode to realize, the injection hemostix has syringe, the syringe front end is processed with the syringe needle socket, be the syringe inlet, be processed with crossette, notch on the syringe needle socket, have brace on the crossette, be connected with gag, being processed with taper hole in the gag is that blind hole, gag lid oral area are processed with convex, match with syringe needle socket notch, pinhead sleeve is contained in syringe needle socket front end.Push rod is housed in the syringe, and push rod is the cross push rod, vacancy on every side, and the rear portion is a flat shape; Front end is equipped with piston, has elasticity and syringe good airproof performance, because push rod is cross, the little promotion of frictional resistance is easy less with the syringe contact surface during use.Be processed with inner wall trench on the syringe rear inside wall, gas can be entered by groove and can not cause negative pressure to avoid erythrocyte hemolysis in the injector syringe when blood drawing finished to take out push rod, can prevent that also blood from spattering outward.Also be processed with scale on the syringe outer wall.

The injection hemostix both can be used as common disposable syringe and had used, also can be used as disposable blood taking device uses, as the hemostix time spent, when blood sampling volume reached requirement, syringe needle was head-up dialled syringe needle, immediately gag was covered on the syringe needle socket, owing to be processed with convex in the gag, have the internal taper hole gag and be about to the syringe good seal, dial when removing push rod the syringe front end and can conveniently transfer to push rod down, be about to syringe and use as blood sampling test tube.

The injection hemostix once the property syringe had easy to use, cost is low, the advantage of no cross infection, both having can be used as syringe uses, can make hemostix again, the blood sampling test tube use is done as long as extract gag on the syringe drive end bearing bracket out push rod in the blood drawing back, does not have any pollution channel.Because gas can enter in the syringe when syringe inwall had groove taking-up push rod, can not cause negative pressure, avoided erythrocyte hemolysis and blood to spill from syringe.When doing the blood sampling test tube use, easy to use because of being marked with scale on the syringe.

The utility model is described in further detail below with reference to accompanying drawing

Fig. 1 is an injection hemostix structural representation

Fig. 2 is the sketch map that this utility model syringe is done the blood sampling test tube time spent

Has syringe (9) with reference to accompanying drawing injection hemostix primary structure, the syringe front end is processed with at socket (7) and is inserted with syringe needle (1), the middle part is processed with inlet and communicates with syringe, the syringe outside indicates containing mark (12), syringe needle socket rear portion is processed with crossette (6), notch (4), have brace (5) on the crossette, brace links gag (2), being processed with taper hole in the gag is blind hole, it is similar to syringe needle socket notch size that the gag oral area has convex (3) convex, convex is stuck in the notch when gag is enclosed within on the syringe needle socket, and it is fabulous that taper hole tightly is enclosed within on the syringe needle socket sealing property.Syringe (9) rear inside wall is processed with some grooves (11).Push rod (10) is housed in the syringe, and push rod is a decussate texture, and the push rod front end is equipped with piston (8), adopts the nontoxic rubber plastics to make.

Claims

1, a kind of injection hemostix with syringe, syringe needle, push rod, piston is characterized in that being processed with crossette, notch on the syringe front end syringe needle insertion mouth, has brace on the crossette, is connected with gag, is processed with inner wall trench on the syringe rear inside wall.

2, injection hemostix according to claim 1 is characterized in that being processed with in the gag taper hole, and gag lid oral area is processed with convex, matches with notch on the syringe needle socket.
