Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, in particular to an injection-type liquid medicine pushing device. Background Art

[0002] Medical injection is the process of extracting and injecting gas or liquid with a needle. The syringe consists of a syringe with a small hole at the front end and a matching piston core rod, which is used to inject a small amount of liquid or gas into or extract it from areas that are inaccessible by other methods. When the core rod is pulled out, the liquid or gas is sucked from the small hole at the front end of the syringe, and when the core rod is pushed in, the liquid or gas is squeezed out.

[0003] The principle of the syringe is mainly to change the internal volume by the movement of the piston, so as to achieve the inhalation and discharge of the drug. When the piston is pulled back, the volume increases, forming a negative pressure, and the drug is sucked into the syringe; when the piston is pushed forward, the volume decreases, forming a positive pressure, and the drug is pushed out of the syringe. The syringe is mainly used for injection and sample extraction. The injected drugs mainly include liquid drugs, suspensions, emulsions, etc. Through the syringe, the drug can accurately enter the patient's body to play a role in treatment and symptom relief. In clinical diagnosis, doctors need to extract samples such as blood, urine, cerebrospinal fluid, etc. from patients for testing; syringes can be used to accurately and quickly extract samples to provide a basis for the diagnosis of the disease. In the prior art, ordinary syringes are only suitable for small-dose administration. When injecting large doses of drugs such as lavage fluids, the commonly used push injection device is not easy to disassemble, so the cleaning process after the injection is completed is more cumbersome.
