Abstract

The invention provides a disposable syringe. The disposable syringe comprises a sleeve, a push rod, a syringe needle and a piston, wherein the piston is connected to the lower end of the push rod, and is arranged in the sleeve together with the push rod in a sleeving way; the front end of the sleeve protrudes to form a medicinal liquid supply port; the syringe needle is separately combined with the medicinal liquid supply port; the bottom of the push rod is provided with a cavity of which the shape and size correspond to the syringe needle. After use, the syringe needle can be pressed into the corresponding cavity in the bottom of the push rod, so that the syringe needle is prevented from being taken out easily, repeated use of the disposable syringe can be prevented effectively, and the health of patients is protected effectively; meanwhile, potential harm due to random placement of the syringe needle after use is avoided.

Description

technical field [0001] The invention relates to a syringe, in particular to a disposable syringe. Background technique [0002] A syringe is a fairly common medical product, which injects medicine into a patient's body to achieve a therapeutic effect. Generally speaking, the medical staff first introduces the medicine into the syringe, and then injects the medicine into the patient's body through the needle on the syringe. [0003] In terms of practical use, there are many potential risk factors in traditional syringes. When used improperly, it will cause very serious harm and adverse effects on the health of patients. [0004] Wherein, a main problem is that the traditional syringe is extremely easy to have the problem of reusability, and its reason is that the structure of the traditional syringe cannot avoid reuse, so those who are interested can still easily reuse the syringe. [0005] For example, when a syringe injects medicine into a patient's body, the patient's b...
