Abstract
The utility model relates to a one-off test tube blood sampler, which comprises a test tube and a sealing plug arranged at the upper end of the test tube; wherein, a liquid inlet pipe and an exhaust pipe are arranged on the sealing plug; the liquid inlet pipe is connected with a pinhead by a transfusion hose; the exhaust pipe is connected with an injector connector by an exhaust hose; and the outer wall of the test tube is provided with a graduation mark. The one-off test tube blood sampler has the excellent advantages of simple structure; when in use, the injector is connected with the injector connector; the pinhead is used for puncturing; after the puncturing is successful, the air in the test tube is pumped out by the injector and a subpressure generates in the test tube; the blood ceaselessly enters the test tube through the transfusion hose and the liquid inlet pipe; therefore, the one-off test tube blood sampler is conveniently used; the collected blood directly enters the test tube; a blood sample can not be polluted; and the graduation mark is arranged on the wall of the test tube, thus being more accurate and convenient to pump in or extract the blood sample.
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 exhaustor, be connected with syringe needle by infusion tube on the described feed tube, be connected with the syringe union joint by exhaust hose on the described exhaustor, 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, syringe is connected on the syringe union joint, puncture with syringe needle, puncture successfully after, extract invisible spectro air out with syringe, in vitro produce negative pressure, blood continuously enters in vitro by infusion tube and feed tube, and easy to use, the blood of being gathered directly enters test tube, blood sample can not pollute, test tube wall is provided with graduation mark, and 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, sealing-plug 2, syringe needle 3, infusion tube 4, feed tube 5, exhaustor 6, exhaust hose 7, syringe union joint 8 and graduation mark 9 when embodiment of the present utility model implemented.Wherein, test tube 1 upper end is provided with sealing-plug 2, and sealing-plug 2 is provided with feed tube 5 and exhaustor 6, is connected with syringe needle 3 by infusion tube 4 on the feed tube 5, be connected with syringe union joint 8 by exhaust hose 7 on the exhaustor 6, 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, syringe is connected on the syringe union joint 8, puncture with syringe needle 3, after puncturing successfully, with the air in the syringe extraction test tube 1, produce negative pressure in the test tube 1, blood continuously enters in the test tube 1 by infusion tube 4 and feed tube 5, and easy to use, the blood of being gathered directly enters test tube 1, blood sample can not pollute, the outer wall of test tube 1 is provided with graduation mark 9, and suction or multiple extraction blood sample are more accurate, convenient, and controls the suction amount or the extracted amount of blood sample easily.
