Abstract
The utility model relates to a disposable test tube hemostix, which comprises a test tube and a sealing plug arranged on the upper end of the test tube, wherein the sealing plug is equipped with a fluid inlet pipe and a piston rod, a piston is arranged on the end portion of the piston rod located on the inner side of the test tube, a pull handle is arranged on the end portion of the piston rod located on the outer side of the test tube, the lower end of the fluid inlet pipe penetrates through the piston to extend to the bottom portion of the test tube, and the upper end of the fluid inlet pipe is connected with a needle through a transfusion hose. The outer wall of the test tube is equipped with scale marks. The utility model has the outstanding advantages that the disposable test tube hemostix is simple in structure, when in use, doctors can push the piston to the bottom portion of the test tube and then pulls up the piston rod and the piston after success puncture, thereby generating negative pressure in the test tube, blood constantly enters the test tube through the transfusion hose and the fluid inlet pipe, which is convenient in operation, besides, collected blood directly enters the test tube, blood samples can't be polluted, and the test tube wall is equipped with the scale marks, thereby enabling blood sample suction or extraction to be more accurate and more convenient.
Description
Technical field:
This utility model relates to technical field of medical instruments, particularly a kind of disposable test blood sampling tube device.
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 disposable test blood sampling tube device that blood sample pollutes.
To achieve these goals, this utility model provides a kind of disposable test blood sampling tube device, 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 end that is positioned at the described piston rod in the described test tube outside is provided with handle, the bottom that described piston extends described test tube is passed in the lower end of described feed tube, and the upper end of described feed tube is connected with syringe needle by infusion tube.
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, handle 7, piston rod 8 and graduation mark 9 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 8, the end that is positioned at the piston rod 8 of test tube 1 inboard is provided with piston 2, the end that is positioned at the piston rod 8 in test tube 1 outside is provided with handle 7, 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 9.
Disposable test blood sampling tube device 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, catch handle 7 to be pulled upwardly piston rod 8 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 9, suction or multiple extraction blood sample are more accurate, and be convenient, controls the suction amount or the extracted amount of blood sample easily.
