Abstract
The utility model discloses a medicinal blood collecting device which comprises a syringe, a syringe needle, a test tube and a blood introduction pipe, wherein, the syringe is cylindrical; the front end of the syringe is provided with the syringe needle; the test tube is positioned in the syringe and is also used as a piston; the front end of the test tube is sealed by a rubber plug; a through hole is arranged on the rubber plug; one end of the blood introduction pipe is communicated with the syringe needle, and the other end extends into the test tube through penetrating the rubber plug. Compared with the blood collection through a common syringe, the medicinal blood collecting device integrates the injector with the test tube, the blood collection with the storage, thus the operation processes are reduced, blood samples are not exposed in the air, the pollution and the cross infection of the blood samples are voided, the operation is simple, and the cost is low.
Description
Technical field
This utility model belongs to technical field of medical instruments, relates in particular to a kind of device of convenient blood sampling chemical examination.
Background technology
The patient is when diagnosis and treatment, health check-up, often needing to extract blood preparation chemically examines and adopts the blood collection needle method in the past, after promptly extracting blood by syringe, blood injected post chemical examination label, worn-out mouthful in vitro, blood sample directly contacts with air, causes blood sample to pollute easily, influences analytical quality, time-consuming, poor stability.
Chinese patent discloses a kind of " disposable blood taking device ", and it is to be made of syringe needle, joint, syringe, piston, push rod.External screw thread and female thread joint lower end inner arm on of syringe by the upper end is tightly connected and is one, and syringe needle is by being sleeved on the nipple of joint from one's body needle stand.There is an annular recess bottom surface of piston, is provided with and the corresponding nested localized ring-type retainer ring of annular recess on the inner arm of syringe bottom.Still there is complex structure, unhandy problem.
Summary of the invention
The purpose of this utility model is exactly the problem that exists at existing hemostix, a kind of medical blood-taking device is provided, and this medical blood-taking device has centralized procurement blood, hold function in one, has avoided cross infection and blood contamination, can guarantee the primitiveness of blood sample, easy and simple to handle, cost is low.
The purpose of this utility model is to realize like this, this medical blood-taking device comprises syringe, syringe needle, test tube, emissary vein part, described syringe is a cylindrical shape, the front end of described syringe is equipped with syringe needle, described test tube is positioned at syringe double as piston, the outer wall of described test tube combines with the inner wall sealing of syringe, test tube can be twitched in syringe, the front end of described test tube is by a rubber stopper seal, described rubber stopper is provided with a through hole, one end of described emissary vein is communicated with syringe needle, and the other end passes rubber stopper and stretches in vitro.
During use, syringe needle is thrust in the vein, spur test tube backward, the syringe front end forms negative pressure, because rubber stopper is provided with the through hole that is communicated with syringe front end and test tube, thus negative pressure in vitro also formed, at this moment under the effect of negative pressure in vitro, blood in the vein enters in the test tube by syringe needle, emissary vein, treats that extracting test tube out after blood sampling is finished can inspect by ready samples.
The beneficial effects of the utility model are: compare with taking a blood sample with ordinary syringe, because syringe and test tube become one centralized procurement blood, preservation and one, reduced operating process, blood sample is not exposed in the air, has stopped pollution and cross infection to blood sample, easy and simple to handle, cost is low.
Description of drawings
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing
Fig. 1 is a cutaway view of the present utility model
Among the figure: 1, syringe 2, syringe needle 3, test tube 4, emissary vein 5, rubber stopper 6, through hole
The specific embodiment
As shown in Figure 1, this medical blood-taking device comprises syringe 1, syringe needle 2, test tube 3, emissary vein 4 parts, and syringe 1 is a cylindrical shape, can use pmma material earlier, the front end of syringe 1 is equipped with syringe needle 2, test tube 3 is positioned at syringe 1 double as piston, and the outer wall of test tube 3 combines with the inner wall sealing of syringe, and test tube 3 can be twitched in syringe 1, the front end of test tube 3 is by a rubber stopper 5 sealings, rubber stopper 5 is provided with a through hole 6, and an end of emissary vein 4 is communicated with syringe needle 2, and the other end passes rubber stopper 5 and stretches in the test tube 3.
During use, syringe needle 2 is thrust in the vein, spur test tube 3 backward, syringe 1 front end forms negative pressure, because rubber stopper 5 is provided with the through hole 6 that is communicated with syringe 1 front end and test tube 3, thus also formed negative pressure in the test tube 3, this moment negative pressure in test tube 3 effect under, blood in the vein enters in the test tube 3 by syringe needle 2, emissary vein 4, treats that extracting test tube 3 out after blood sampling is finished can inspect by ready samples.
