Preparation syringe integrated structure

Abstract

The invention discloses a preparation syringe integrated structure. The preparation syringe integrated structure comprises a stretchable piston, a needle cylinder, a syringe needle, an exposed rubberplug, a sealing fin, a built-in rubber plug, a sealing rubber plug and a cohesion rubber plug, a stretchable piston is arranged at one end of the needle cylinder, and a clamping column is arranged atthe other end of the needle cylinder, the exposed rubber plug is mounted on one side of stretchable piston, away from the needle cylinder, the built-in rubber plug is mounted in the needle cylinder, scale lines are formed on the circumference surface of the needle cylinder. According to the preparation syringe integrated structure, a storage medicine bottle and a syringe are designed as an integrated structure, intermediate links are reduced, and thus the waste of the liquid medicine caused by incomplete liquid medicine suction and liquid medicine overflowing is reduced, at the same time, professional risks of medical workers are reduced, and the problem that particle formed due to repeated puncture causes the potential injure to a patient is reduced; the matched stretchable piston structure reduces the overall length, and provides convenience for the operation of puncturing; and by the syringe needle, of which the section is of an epsilon-shaped structure, the waste of the liquid medicine is effectively avoided as well.

Description

technical field [0001] The invention belongs to the technical field of syringes, and in particular relates to a preparation syringe with an integrated structure. Background technique [0002] It is a common clinical medical behavior to perform various injection treatments after preparing liquid medicine through sealed bottles. There are usually two types of medicines in sealed bottles, liquid or powder injections, among which powder injections are more common, which need to be dissolved into liquids through a solvent, and then used after being sucked into a syringe. In the process of using the traditional syringe to suck the liquid medicine and inject it, there are mainly the following problems: 1. The waste of the medicine liquid is mainly caused by the following factors: the extravasation of the medicine liquid. As the pressure increases, the liquid medicine may overflow from the needle, and at the same time, the liquid medicine exuded can form toxic particulate aerosol o...

Problems solved by technology

In the process of using the traditional syringe to suck the liquid medicine and inject it, there are mainly the following problems: 1. The waste of the medicine liquid is mainly caused by the following factors: the extravasation of the medicine liquid. As the pressure increases, the liquid medicine may overflow from the needle, and at the same time, the liquid medicine exuded can form toxic particulate aerosol or aerosol, which is invisible to the naked eye, and then cause harm to medical staff and environmental pollution through the skin, respiratory tract, etc.; liquid suction Endless, due to the special structure of the sealed bottle, the wall-mounted droplets and the liquid medicine remaining in the sealing ring of the bottle mouth cannot be sucked out; the liquid medicine is injected endlessly, and part of the liquid medicine remains in the needle plug when using a traditional syringe

2. The possibility of bacterial contamination increases. Powder injections usually require the syringe to enter and exit twice to dissolve the drug and suck the drug. In this process, the possibility of contamination of the liquid medicine and the syringe is greatly increased; The sealing ring is made of rubber-like materials, repeated punctures may cause particles to enter the liquid medicine, thereby bringing potential harm to patients; 4. In the process of preparing the liquid medicine, repeated dissolution and suction of the liquid medicine consume time and manpower
