Auxiliary injecting device

Abstract

The invention discloses an auxiliary injecting device. The auxiliary injecting device comprises an injector and an auxiliary device; one end of the injector is fixedly provided with a needle, a piston is slidingly connected inside the injector, one end of the piston, which is away from the needle, is provided with a push rod, and one end of the push rod, which is away from the needle, is provided with a push block; the auxiliary device comprises a cannula, a push plate, an extending rod, a motor and a cap, one end of the cannula is provided with a through hole with a diameter smaller than that of the injector, the injector is fixed at one end of the cannula, the push plate is slidingly connected inside the cannula, the middle of the push plate is provided with a groove matched with the push block, the center of one end of the push plate, which is away from the push block, is perpendicularly and fixedly provided with the extending rod, and the extending rod penetrates through the cap and is fixedly connected with the output shaft of the motor. According to the auxiliary injecting device, the outside of the cannula is provided with a handle case to facilitate injection; the handle case is made of rubber to achieve anti-slip effects; a limit block is arranged to maintain stability of the push plate.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an auxiliary injection device. Background technique [0002] Syringes are a common medical appliance. As early as the 15th century, Italian Catinel proposed the principle of syringes. It consists of a syringe with a small hole at the front end and a matching piston core rod, and is mainly used for injecting or drawing liquid. [0003] At present, in the process of treating patients with cardiovascular diseases, in order to accurately understand the patient's vascular conditions, it is often necessary to inject contrast media into the blood vessels through a syringe for angiography. The syringe injects the medium, but because the intervention medium is relatively viscous, it is very troublesome to operate, time-consuming and laborious, the injection speed is difficult to control, the injection force is not uniformly controlled, the injection stability is poor, and the s...

Problems solved by technology

[0003] At present, in the process of treating patients with cardiovascular diseases, in order to accurately understand the vascular conditions of patients, it is often necessary to inject contrast agents into blood vessels through injectors for angiography. The syringe injects the medium, but because the intervention medium is relatively viscous, it is very troublesome to operate, time-consuming and laborious, the injection speed is difficult to control, the injection force is not uniformly controlled, the injection stability is poor, and the sleeve is easy to shake during operation. As a result, the needle will be displaced, which will easily lead to the leakage of contrast agent and affect the diagnosis and treatment effect.
