Abstract

A one-off phlebotomizing needle of the utility model belongs to the medical treatment technology field. The utility model consists of a needle head, a needle cylinder, a piston, a needle bolt, a needle head cap, an elastic sleeve. The needle head is connected on connecting seat of the needle head which is arranged on the front end of the needle cylinder, the outside of the needle is covered by the needle head cap, the airproof piston inside the needle cylinder connects with the needle bolt fixedly. The utility model is characterized in that the front outer wall of the needle head cap is sleeved by the elastic sleeve which matches the needle head connecting seat, and an aeration groove, which communicates with the end of the needle cylinder, is arranged on the rear internal wall of the needle cylinder. The utility model has the advantages that the blood taking needle cylinder containing the blood sample can be directly placed in the centrifuge to separate the blood serum, which can avoid the problem of effecting the results of checking by hemolysis which can be caused by carelessness in the process of infusing blood with the present blood taking device, and can ensure the accuracy of the checking result. At the same time, for saving the one-off test tube, the utility model can lower the blood testing cost, reduc the environmental pollution.

Description

The disposable vein blood taking needle
Technical field
This utility model belongs to technical field of medical instruments, a kind of specifically disposable vein blood taking needle.
Background technology
Present blood sampling checkout procedure generally is such, earlier uses the hemostix blood sample collection, again with blood sample injecting tube (or other vessel), then blood sample is carried out the check of various projects after with the centrifuge separation of serum.Do both loaded down with trivial detailsly like this, cause haemolysis because of annotating the blood careless manipulation easily again, influence the accuracy of assay.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of blood sampling chemical examination easy, is difficult for causing haemolysis, guarantees testing result disposable vein blood taking needle accurately.
The purpose of this utility model is achieved in that this disposable vein blood taking needle is made of syringe needle, syringe, piston, pintle, needle cap, elastic cover, syringe needle is connected on the syringe needle Connection Block of syringe front end, the syringe needle outside is with needle cap, the packed-piston of syringe inside is fixedlyed connected with pintle, on needle cap front end outer wall, be with and the suitable elastic cover of syringe needle Connection Block, on syringe afterbody inwall, be provided with a vent grooves that communicates with the syringe end.
Concrete when using this utility model, process blood sample collection at first routinely is when piston retreats to the vent grooves front end, take off syringe needle, elastic cover is enclosed within on the syringe needle Connection Block, holds up syringe, the syringe needle Connection Block is downward, continue upwards pull piston, when piston all passed through the vent grooves front end, the syringe internal cavities communicated with atmosphere by vent grooves, and negative pressure automatically terminates, piston can be extracted easily, at this moment syringe is put into directly that separation of serum gets final product in the centrifuge.Because degree of tightness is locked and is enclosed within on the syringe needle Connection Block, needn't worry that it can come off because of centrifugal force.
Advantage of the present utility model: can directly put into the centrifuge separation of serum owing to contain the blood sampling syringe of blood sample, thereby overcome existing hemostix in notes blood process because of careless manipulation causes haemolysis, influence the problem of assay, guaranteed the accuracy of assay; Owing to saved disposable test tube, reduce the blood count cost simultaneously, reduced environmental pollution.
Description of drawings
Accompanying drawing is the cutaway view of this utility model along centrage.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail: this disposable vein blood taking needle is made of syringe needle 1, syringe 2, piston 3, pintle 4, needle cap 5, elastic cover 6, syringe needle 1 is connected on the syringe needle Connection Block of syringe 2 front ends, syringe needle 1 outside is with needle cap 5, the packed-piston 3 of syringe 2 inside is fixedlyed connected with pintle 4, on needle cap 5 front end outer walls, be with the elastic cover 6 suitable, on syringe 2 afterbody inwalls, be provided with a vent grooves 7 that communicates with syringe 2 ends with the syringe needle Connection Block.
