Abstract
The utility model relates to a blood test tube, which comprises a test tube and a closing plug set on upper end of the test tube, wherein, the closing plug is provided with a inlet tube and a cylinder rod; terminal end of the cylinder rod in inner side of the test tube is provided with a piston; lower end of the piston is in circular arc shape; lower end of the inlet tube passes through the piston and extends to bottom of the test tube; upper end of the inlet tube passes through a infusion hose and connects with a needle; outer wall of the test tube is provided with a scale line. Remarkable advantages of the utility model are: structure is simple; when using, push the piston to bottom of the test tube; after successful puncture, pull the cylinder rod and the piston upwards so as to generate negative pressure inside the test tube; blood enters into the test tube continuously through the infusion hose tube and the inlet tube; operation is convenient; sampled blood enters into the test tube directly and the blood sample will not be polluted; wall of the test tube is provided with a scale line so that suction or extraction of the blood sample will be more accurate and convenient.
Description
Technical field:
This utility model relates to technical field of medical instruments, particularly a kind of blood test test tube.
Background technology:
At present, in medical and health industry, the used utensil of taking a blood sample generally is to adopt disposable syringe, and it is that syringe needle with hollow syringe front end thrusts veins beneath the skin, with blood suction syringe, and then is injected in vitro.This traditional approach formality is loaded down with trivial details, in the time of in injecting tube, destroys the blood sample cell easily; When carrying out various blood examination, also to repeatedly from test tube, extract blood sample, cause blood sample to pollute easily.
Summary of the invention:
The purpose of this utility model is to overcome the shortcoming that exists in the prior art, provides a kind of blood simple in structure, easy to use, that gathered directly to enter test tube and prevents the blood test test tube that blood sample pollutes.
To achieve these goals, this utility model provides a kind of blood test test tube, comprise test tube and the sealing-plug that is arranged on the test tube upper end, wherein, described sealing-plug is provided with feed tube and piston rod, the end that is positioned at the described piston rod of described test tube inboard is provided with piston, the lower end of described piston is set to circular arc, the bottom that described piston extends described test tube is passed in the lower end of described feed tube, the upper end of described feed tube is connected with syringe needle by infusion tube, and the outer wall of described test tube is provided with graduation mark.
The outstanding advantage of this utility model is: simple in structure, during use, piston is pushed into the test tube bottom, after puncturing successfully, be pulled upwardly piston rod and piston, can make and in vitro produce negative pressure, blood continuously enters in vitro by infusion tube and feed tube, easy to operate, the blood of being gathered directly enters test tube, and blood sample can not pollute, and test tube wall is provided with graduation mark, suction or extraction blood sample are more accurate, and be convenient.
Description of drawings:
Fig. 1 is the overall structure front view of this utility model embodiment.
The specific embodiment:
Its design agents mechanism comprised test tube 1, piston 2, feed tube 3, sealing-plug 4, syringe needle 5, infusion tube 6, piston rod 7 and graduation mark 8 when embodiment of the present utility model implemented.Wherein, test tube 1 upper end is provided with sealing-plug 4, sealing-plug 4 is provided with feed tube 3 and piston rod 7, the end that is positioned at the piston rod 7 of test tube 1 inboard is provided with piston 2, the lower end of piston 2 is set to circular arc, the bottom that piston 2 extends test tube 1 is passed in the lower end of feed tube 3, and the upper end of feed tube 3 is connected with syringe needle 5 by infusion tube 6, and the outer wall of test tube 1 is provided with graduation mark 8.
The lower end of piston 2 is set to circular arc, and is identical with the bottom shape of test tube 1, uses more convenient.
Blood test test tube of the present utility model, during use, piston 2 is pushed into the bottom of test tube 1, puncture after the success with syringe needle 5, be pulled upwardly piston rod 7 and piston 2, can make and produce negative pressure in the test tube 1, blood continuously enters in the test tube 1 by infusion tube 6 and feed tube 3, easy to operate, the blood of being gathered directly enters test tube, and blood sample can not pollute, the outer wall of test tube 1 is provided with graduation mark 8, suction or multiple extraction blood sample are more accurate, and be convenient, controls the suction amount or the extracted amount of blood sample easily.
