Abstract
Disclosed is a disposable blood taking needle which belongs to the medical device technical field. The utility model comprises a needle head (1), a needle cylinder (2), a test tube (3) and a piston cap (4) and is characterized in that a blood guiding tube (5) whose length is the same as the length of the needle cylinder (2) is arranged in the cylinder and is communicated with the connecting base of the needle head (1); an annular projection is arranged on the external wall of the test tube (3); a piston cap with a circular hole in the middle of the piston cap is in threaded connection with the external wall on the front end of the test tube (3); the piston cap (4) is in sliding and sealing connection with the inner wall of the needle cylinder (2); and the lower end of the blood guiding tube (5) is threaded through the circular hole on the piston cap to extend to the test tube (3). The utility model has the advantages that the blood flows into the test tube directly; the blood taking is convenient; the blood pollution is reduced; the blood sample cells are not destroyed; the friction between the hand and the external wall of the test tube because of the annular projection on the external wall of the test tube; and the test tube is convenient for drawing.
Description
Technical field
This utility model belongs to technical field of medical instruments, specifically disposable blood taking needle.
Background technology
At present public hemostix and method is, thrusts veins beneath the skin with the syringe needle of disposable syringe front end, with blood suction syringe, and then is injected in vitro.This traditional approach formality is loaded down with trivial details, when moving in vitro, destroys the blood sample cell easily, when carrying out various blood examination, repeatedly extracts blood sample from test tube, causes blood sample to pollute easily.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of simple in structure, easy to operate, and the blood of being gathered directly enters test tube, does not destroy the disposable blood taking needle of blood sample cell.
The purpose of this utility model is achieved in that this disposable blood taking needle is made of syringe needle, syringe, test tube, piston cap, be provided with in syringe inside length identical with syringe length and communicate with the syringe needle Connection Block draw blood vessel, the test tube outer wall is provided with annular protrusion, round-meshed piston cap in the middle of test tube front end outer wall thread is connecting, piston cap is connected with the slipper seal of syringe inwall, draws the circular hole that the lower end of blood vessel passes on the piston cap and extend in the test tube.
During blood sampling, syringe needle thrusts veins beneath the skin, and the pulling test tube can be pumped into blood in the test tube, and the piston cap of laying down the test tube front end can carry out blood test.
Advantage of the present utility model: blood directly enters test tube, and it is easy to take a blood sample, and reduces blood contamination, does not destroy the blood sample cell; Annular protrusion on the test tube outer wall has increased the frictional force between hands and the test tube outer wall, is convenient to the pull of test tube.
Description of drawings
Accompanying drawing is the cutaway view of this utility model along centrage.
The specific embodiment
Make this utility model with reference to accompanying drawing: this disposable blood taking needle is made of syringe needle 1, syringe 2, test tube 3, piston cap 4, be provided with in syringe 2 inside length identical with syringe 2 length and communicate with syringe needle 1 Connection Block draw blood vessel 5, test tube 3 outer walls are provided with annular protrusion, round-meshed piston cap 4 in the middle of test tube 3 front end outer wall threads are connecting, piston cap 4 is connected with syringe 2 inwall slipper seals, draws the circular hole that the lower end of blood vessel 5 passes on the piston cap 4 and extend in the test tube 3.
Claims (1)
1. disposable blood taking needle, constitute by syringe needle (1), syringe (2), test tube (3), piston cap (4), it is characterized in that syringe (2) inside be provided with length identical with syringe (2) length and communicate with syringe needle (1) Connection Block draw blood vessel (5), test tube (3) outer wall is provided with annular protrusion, round-meshed piston cap (4) in the middle of test tube (3) front end outer wall thread is connecting, piston cap (4) is connected with syringe (2) inwall slipper seal, draws the circular hole that the lower end of blood vessel (5) passes on the piston cap (4) and extend in the test tube (3).
