Abstract
Description
Technical Field
[0001] The utility model relates to a needle assisting device, in particular to a novel needle assisting device. Background Art
[0002] The needle assisting device, as a common medical device, is widely used in the medical field. Its main function is to accurately inject drugs into the human body. In China, the traditional operation method of the syringe has always relied on medical staff to manually push the syringe plunger, which to a large extent ensures the safe delivery of drugs. However, at the same time, there are also some risks that cannot be ignored in this operation method.
[0003] First of all, needle injury is a potential risk. During the injection process, the hand operation of medical staff may cause the needle to injure the patient, resulting in pain or even infection. Especially when injecting drugs with high-speed flow, if not careful, it may also cause drug splashing, posing a threat to both medical staff and patients.
[0004] Secondly, inaccurate drug dosage is also a major problem in the operation process of traditional syringes. Since it is difficult for medical staff to accurately control the drug dosage during the process of manually pushing the syringe plunger, there are often situations where the dosage is too large or too small. For patients, this may lead to poor treatment effects or even side effects. Summary of the Utility Model
[0005] The technical problem to be solved by the utility model is to provide a novel needle assisting device to solve the problems existing in the background art.

By pressing the triggering structure, the injection assembly at the front end of the syringe barrel is placed outside the needle assisting device housing under the action of the thrust spring.
[0008] As a preferred technical solution, the syringe barrel and the needle assisting device housing are guided through a guiding structure, and the guiding structure includes a guiding shaft arranged on the inner side of the needle assisting device housing and a guiding groove arranged on the syringe barrel; a limiting groove is arranged at the end of the guiding shaft, a limiting block is arranged at the end of the guiding groove, and the syringe barrel and the needle assisting device housing are guided and limited through the limiting groove and the limiting block.
[0009] As a preferred technical solution, the triggering structure includes a triggering button arranged on the needle assisting device housing and an elastic buckle arranged on the outer side of the syringe barrel;
