Problems solved by technology

However, it has the following disadvantages: 1. During the process of pulling out the needle and then putting on the cap, air may enter the tube body, which will cause blood sample contamination and affect the test results; It is discharged sequentially, which is not convenient for taking the required blood part in time

Embodiment 1

[0029] Such as figure 1The shown blood sampler for medical examination includes a syringe 1, the bottom of the syringe 1 is provided with an injection port 2, and a needle 3 is installed on the injection port 2, and the syringe 1 is provided with a piston head, a A piston body composed of a push-pull rod and a push-pull handle, the periphery of the piston head is attached to the inner wall of the syringe 1, the push-pull rod is vertically fixed to the middle part of the upper surface of the piston head, and the push-pull handle is fixed to the upper end of the push-pull rod;

[0030] The syringe 1 is provided with an upper piston body 4 and a lower piston body 5. The lower piston body 5 includes a piston head 51 attached to the inner wall of the syringe 1 around the periphery, and a push-pull rod fixed on the middle part of the upper surface of the piston head 51. One 52, and the push-pull handle one 53 fixed on the upper end of the push-pull rod one 52, the upper piston body ...

Embodiment 2

[0035] The difference between this embodiment and Embodiment 1 is that: figure 2 and Figure 5 As shown, the shapes of the first push-pull handle 53 and the second push-pull handle 43 are strip-shaped, and the first push-pull handle 53 is perpendicular to the second push-pull handle 43 . Because the push-pull handle 1 53 has the possibility of attaching the push-pull handle 2 43 when pushing down, at this time, it is relatively inconvenient to pull the push-pull handle 1 53, and the push-pull handle 53 is set as perpendicular to the push-pull handle 2 43, which can be easy to operate all the time Push-pull handle-53.

[0036] Others are the same as embodiment 1.

[0037] The specific application process of the above-mentioned blood collection device for physical examination is (combined with Figure 6 ):

[0038] (1) Preparatory work: push down the push-pull handle 2 43, push the piston head 2 41 to move down through the push-pull rod 2 42, because the lower surface of th...

Abstract

The invention discloses a blood sampling device for medical examination, which belongs to the field of medical equipment and includes a syringe. The syringe is provided with an upper piston body and a lower piston body. The push-pull rod of the lower piston body passes through the upper piston body and extends to the upper piston body. Above the push-pull handle, in the initial state, the lower surface of the piston head of the upper piston body is attached to the upper surface of the piston head of the lower piston body; the piston head of the lower piston body is provided with a through hole that runs through the upper and lower surfaces of the piston head. There is a hydraulically controlled one-way valve that opens upward; the push-pull rods of the upper piston body and the lower piston body are divided into detachably connected upper pull rods and lower push rods; There is an on-off valve. The invention can achieve a better sealing effect and prevent the blood from contacting the air; the centrifuged blood does not need to be discharged sequentially from the bottom to the top, and only the required blood components can be taken at one time; the use of disposable utensils can also be saved, and the Simplify the operation steps.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a blood sampling device for medical examination. Background technique [0002] In the health checkup, blood tests are one of them, usually blood routine and biochemical tests. Blood tests can not only help diagnose diseases, but also help doctors monitor the effect of treatment. Traditionally, when collecting blood for testing, a disposable syringe is generally used to extract blood; in order to facilitate blood transportation and centrifugation, it is necessary to inject the blood in the syringe into a labeled test tube, and then seal the test tube mouth with a sealing cap ; When taking blood for testing, it is necessary to extract the blood in the test tube with a disposable syringe in addition. On the one hand, a large amount of disposable equipment is used, resulting in a large waste; on the other hand, the injection and extraction of blood in the test tube may be in conta...
