Abstract

The invention provides a needle tube structure and an injector with the same, and the needle tube structure comprises a shell which is provided with an injection cavity; a push rod provided with an avoiding channel, wherein the push rod is movably arranged in an injection cavity; and a sealing piece mounted in the avoiding channel; wherein the shell is provided with a connecting part used for being detachably connected with a needle head structure of the injector, the sealing piece is provided with a connector located on the outer side of the avoiding channel, and the connector is used for being connected with a liquid passing core of the needle head structure so as to drive the liquid passing core to retract into the receding channel. The needle tube structure solves the problem that a needle head of the injector easily punctures medical staff in the collecting and processing process, and then spreading of hepatitis B, hepatitis C, AIDS and other diseases is caused, and infection of the medical staff is caused.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a needle tube structure and a syringe with the same. Background technique [0002] Syringes are one of the most basic medical devices. In order to reduce the spread of blood-borne diseases among patients, countries around the world have legislated and promoted the use of disposable safety syringes. [0003] At this stage, the common disposable syringes generally have defects such as reusability and no safety device, and the needle tube is exposed after injection. On the one hand, it is easy to be used by criminals or drug addicts. Repeated use can easily cause virus transmission and cross-infection. [0004] After the use of disposable syringes, the needles of the syringes are easy to puncture the medical staff during the collection process, which will lead to the spread of hepatitis B, hepatitis C, AIDS and other diseases and cause the infection of medical staff. Nurses and waste...
