Optionally, one end of the injection rod 2 extending into the blood drawing tube 1 is provided with a piston 3, and one end of the blood drawing tube 1 far away from the piston 3 is provided with a needle tube 4. The piston 3 is tightly fitted with the inner wall of the blood drawing tube 1 so that the injection rod 2 can be pressed or pulled out by applying a certain force to the injection rod 2 in use. When the injection rod 2 is pressed into the blood pumping pipe 1, the air pressure in the blood pumping pipe 1 is increased, so that the air in the blood pumping pipe 1 is exhausted through the needle tube 4. When the injection rod 2 is pulled out of the blood extraction tube 1, the air pressure in the blood extraction tube 1 is reduced, so that air enters the blood extraction tube 1 through the needle tube 4. The foregoing is prior art and need not be described more fully herein.
In detail, the injection rod 2 is tubular, and a thin film 5 is arranged at one end of the interior of the injection rod 2 close to the needle tube 4. The membrane 5 is a softer material.
