Problems solved by technology

[0002] Syringe is a kind of commonly used medical equipment. The commonly used syringe is mainly composed of a syringe with a piston and a needle connected to the syringe. When in use, the needle is connected to the syringe, and then the drug is extracted for injection; during the injection process The drug in the syringe is pushed out by pushing the piston of the syringe, but during the injection process, due to the special injection site (such as dense connective tissue or scar tissue), the high viscosity of the injection, etc., the required thrust is large and the advancement is difficult. The injection speed is not uniform, and the high propulsion pressure can separate the syringe from the needle, which can easily lead to the occurrence of drug injection, and the use effect is poor
Therefore, existing syringes have the problems of difficult injection advancement, uneven injection speed, and easy separation of the needle and syringe during the injection process.

Abstract

The invention discloses a syringe propelling device which comprises a syringe sleeve (1). The front end of the syringe sleeve (1) is provided with a needle clamping groove, the syringe sleeve (1) is provided with a syringe placement groove (3), a propeller (4) is connected to the tail end of the syringe sleeve (1) and comprises an outer shell, a nut gear (6) is arranged on a propelling screw rod (5) which is arranged in the outer shell, and a transmission gear (8) meshed with the nut gear (6) is arranged on a rotating shaft of a motor (7) which is arranged on the outer shell. The syringe propelling device is convenient to use, injection operation of a syringe can be simplified, uniform injection speed is achieved, injection safety is improved, and separation of a syringe needle and a syringe tube in an injection process is avoided.
