Abstract

The utility model relates to a disposable injector capable of being used as a test tube, which is composed of an injection needle, a needle sleeve, a needle cylinder, a core and a cone-head cap of the injector. After blood is extracted by the injector, the injection needle is pulled out, the cone-head cap is sheathed on the cone head of the needle cylinder and is screwed, the core is then drawn, and the needle cylinder is used as the test tube. The utility model reduces material waste, simplifies operating programs, lowers the contaminated chances of the blood and lowers the contaminated chances for operators.

Description

The disposable syringe that can use as test tube

This utility model is a kind of disposable syringe of using as test tube.

At present, a large amount of disposable syringes that use, only can make liquid medicine injection, the usefulness of blood drawing, when blood drawing, needing had both increased cost with in the blood injecting tube of taking out, the waste resource, many again one formalities, make blood contaminated easily, haemolysis, the operator is easily infected, and when going out to take a blood sample, the blood in the test tube easily on the way comes down in torrents, very inconvenience, in order to address this problem, existing method is in factory test tube to be evacuated, rubber stopper and entry needle are used beyond the Great Wall, though solved above-mentioned subproblem like this, but exist the cost height, run into the not obvious person of blood vessel and be difficult to defectives such as operation.

The purpose of this utility model provides a kind of disposable syringe of using as test tube.It is injectable medicinal liquid, blood drawing both, the usefulness of again can syringe containing blood, separation of serum as test tube.

The purpose of this utility model is achieved in that and can be made up of entry needle, needle guard, syringe, fuse and syringe conehead lid as the disposable syringe that test tube is used.The interior shape of syringe conehead lid and the profile of syringe conehead are coincide.Behind the syringe draw samples, remove entry needle, the conehead lid is screwed on the syringe conehead, make the conehead sealing, extract fuse then out, this moment, syringe promptly can be used as the test tube use.

For syringe conehead lid is connected firmly with the syringe conehead, they can be by being threaded.

Syringe conehead exit seal can be able to be put into rubber blanket in the inside bottom of conehead lid in order to make syringe conehead lid.

The disposable syringe that has extracted blood or medicinal liquid and used as test tube is unlikely when extracting fuse out to pollute the syringe mouth in order to make, and the syringe oral area can be expanded into horn-like.Its horn-like angle is at 5～90 degree.

When the disposable syringe that can use as test tube uses entry needle is enclosed within on the syringe conehead and screws, blood drawing, screw off entry needle then, with on the conehead lid cover top cylinder conehead and screw, the conehead lid is about to the sealing of conehead mouth, put into test tube rack, send into control laboratory, extract fuse out at control laboratory, syringe promptly can be used as test tube and uses, and blood is done every check.The disposable syringe that this can use as test tube has the minimizing operating procedure, and economical with materials improves the advantage of sampling quality.

Below in conjunction with drawings and Examples this utility model is further specified.

Accompanying drawing is the vertical section structure figure of the disposable syringe embodiment that can use as test tube.

Among the figure: 1. conehead covers 2. rubber blankets, 3. coneheads lid screw thread, 4. coneheads, 5. syringe screw threads

6. syringe 7. fuses 8. syringe mouths 9. needle guards 10. entry needles

In the accompanying drawing illustrated embodiment, conehead lid (1), syringe needle (6), needle guard (9), fuse (7) is by the plastics manufacturing, entry needle (10) is by the metal manufacturing, rubber blanket (2) is by the rubber manufacturing, then their sterilizations are packed, entry needle during use (10) is enclosed within on the conehead (4) of syringe (6), after twitch fuse (7) blood drawing, pull up entry needle (10), conehead lid (1) is put conehead (4) and screw, the external screw thread (3) on the conehead lid (1) is just engaged with the syringe female thread (5) that extends at the bottom of the syringe of conehead (4) outside, and the rubber blanket (2) in the conehead lid (1) is sealed the mouth of conehead (4) simultaneously, put into test tube rack then and send control laboratory, in control laboratory, extract fuse (7) out,, can avoid the hemophoric pollution of fuse (7) because syringe mouth (8) becomes horn-like expansion.

Claims

1, a kind of disposable syringe of using as test tube, by syringe needle (10), needle guard (9), syringe (6), fuse (7) and syringe conehead lid (1) are formed, and it is characterized in that: be added with the conehead lid (1) that matches with syringe conehead (4); Conehead lid (1) is to link to each other by screw thread with being connected of syringe (6).

2, the disposable syringe of using as test tube according to claim 1 is characterized in that in the conehead lid (1) rubber blanket (2) being arranged.

3, the disposable syringe of using as test tube according to claim 1 is characterized in that syringe mouth (8) becomes horn-like expansion, and its horn-like angle is at 5～90 degree.
