Abstract

The invention discloses a syringe and relates to the technical field of medical instruments. The syringe is mainly invented for solving the problem that an existing syringe is large in injection speedfluctuation. The syringe comprises a shell, wherein one end of the shell is sleeved with an injection device, and the other end of the shell is sleeved with a main push rod; one end of the main pushrod penetrates through a propelling port and is fixedly connected with a connecting device arranged in the shell, and the end, away from the main push rod, of the connecting device is fixedly connected with one end of the injection device; the surface of the main push rod is sleeved with a propelling clamping ring, and the side surface, close to the injection device, of the propelling clamping ring is fixedly provided with a propelling rod; the end, away from the propelling clamping ring, of the propelling rod is inserted into an air chamber and is fixedly connected with a second piston arranged in the air chamber; the air chamber is fixedly arranged on the inner wall of the shell, and an air outlet communicated with the outside of the shell is formed in one side surface, away from the propelling rod, of the air chamber. The syringe has the advantage that the injection speed is uniform.

Description

technical field [0001] The invention relates to the technical field of medical instruments. Background technique [0002] Due to the different proficiency of the medical staff in using the syringes in the existing needle tubes, the pushing speed during injection is very unstable, which makes the injection speed of the syringes fluctuate greatly, and it is easy to make the patients feel uncomfortable. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a needle tube with uniform pushing speed. [0004] The above purpose is achieved in the following way: it includes a casing, one end of the casing is sleeved with an injection device, the other end of the casing is sleeved with a main push rod, and one end of the main push rod passes through the propelling port and is connected with the The internal connection device is fixedly connected, and the end of the connection device away from the main push rod is fixedly conne...
