Abstract
A disposable vein blood collecting device belongs to the technical field of medical instruments and consists of a needle cylinder, a piston, a needle plug and a needle needle cylinder cap. The disposable vein blood collecting device is characterized in that the interior of the needle cylinder is connected with the piston with the needle plug in a sliding and sealing way; a sealing plug is arranged in a needle head seat at the front end of the needle cylinder; the sealing plug is fixedly connected with the needle cylinder cap which is sheathed at the front end of the needle cylinder; and the side wall at the back end of the needle cylinder is provided with a through hole which is communicated with an internal cavity of the needle cylinder. The disposable vein blood collecting device has the advantages that as the blood collecting needle cylinder which holds the blood sample can be directly placed in a centrifuge for separating serum, the problem that the existing blood collecting device causes blood hemolysis due to careless operation in the blood injecting process so as to influence the test result is solved, thereby ensuring the accuracy of the test result. Simultaneously, as the disposable test tube is saved, the blood testing cost is lowered and the environmental pollution is reduced.
Description
Technical field
This utility model belongs to technical field of medical instruments, specifically a kind of disposable vein hemostix.
Background technology
Present blood sampling checkout procedure generally is such, earlier uses the blood taking needle 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 hemostix accurately.
The purpose of this utility model is achieved in that this disposable vein hemostix is made of syringe, piston, pintle, syringe medicated cap, the syringe slides within is being tightly connected and is having the piston of pintle, be provided with sealing-plug in the needle holder of syringe front end, sealing-plug is fixedlyed connected with the syringe medicated cap that is sleeved on the syringe front end, and the back end of syringe sidewall is provided with the through hole that communicates with the syringe inner chamber.
During use, pinhead sleeve is contained on the needle holder of syringe front end, routinely the process blood sample collection, in the time of near piston retreats to back end of syringe sidewall through hole, take off syringe needle, the syringe cap sleeve that will have sealing-plug is contained in the syringe front end, sealing-plug is sealed needle holder, needle holder is downward then, holds up syringe, continues upwards pull piston, this moment, the syringe inner chamber communicated with atmosphere by through hole, negative pressure automatically terminates, and piston can be extracted easily, then syringe is put into directly that separation of serum gets final product in the centrifuge.
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.
