Abstract

The invention relates to a novel low-resistance injection syringe. The low-resistance injection syringe comprises a sleeve, a push rod, a fixed seat, a rubber plug and a piston cap; the piston in thesleeve is connected with the push rod, the piston cap is installed at the bottom end of the push rod, the rubber plug is installed at the top end of the piston cap, and a sealing line is designed on the rubber plug; the fixed seat is assembled at the top end of the rubber plug, the top end of the piston cap is connected with a bottom surface of the push rod, V-shaped or U-shaped bulges are designed under the piston cap, V-shaped or U-shaped grooves are designed in the bottom surface of the rubber plug, and the contact area is increased through extrusion deformation of the V-shaped or U-shapedbulges and the V-shaped or V-shaped grooves. Compared with the prior art, the injection syringe has the advantages that a gap is designed between the top surface of the fixed seat and the bottom surface of the push rod, the push rod of the injection syringe can swing flexibly, so that medical personnel can operate freely, and meanwhile, when the push rod is moved, the rubber plug can actively search for a contact surface in the sleeve, so that the resistance of pushing the rubber plug by workers is reduced, the sealing effect is ensured, the labor intensity of the workers is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of syringes, in particular to a novel low-resistance syringe. Background technique [0002] A syringe is a commonly used medical device in clinical practice. It is mainly used to inject gas or liquid. 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 the gap between the piston and the cylinder No leakage occurs. In order to ensure a good sealing effect between the piston and the cylinder, there is a large resistance between the piston and the cylinder. When the staff uses the syringe to inject, they need to use a large force, which increases the labor of the staff. strength, reducing work efficiency. Contents of the invention [0003] The present invention provides a new type of low-resistance syringe, which can effectively solve the problem of relatively high resistance of the syringe proposed in the...
