Description

technical field [0001] The invention belongs to the field of medical equipment, in particular to a syringe. Background technique [0002] A syringe is a commonly used medical device in clinical practice. It is usually composed of a cylinder, a piston, and a core rod. The above-mentioned syringe is generally composed of polymer materials. In order to prevent leakage between the piston and the cylinder, there is a good For the sealing effect, there must be sufficient interference between the piston and the cylinder, but the large interference makes the operator need to use a large force to move the piston. In addition, there are also glass syringes, which are usually composed of a cylinder and a core rod. The friction between the core rod and the cylinder is small, the resistance is small, and the sliding performance is excellent. However, this type of syringe cannot be recycled, and the cost is high, causing hidden dangers to patients. . Contents of the invention [0003]...
