Sterile opening method and device of medical ampoule bottle

Abstract

The invention discloses a sterile opening method and device of a medical ampoule bottle. The device is composed of a sealing box body, a clamping and rotating mechanism, a sawing mechanism, a cleaning and disinfecting mechanism, a chip removing mechanism, a breakoff mechanism, a waste collecting mechanism and an electric control system. By means of reasonable depth and length sawing, liquid gas disinfecting and outward-pulling breakoff on the ampoule bottle, negative pressure lower than the pressure in the ampoule bottle is generated outside the ampoule bottle, and fewest glass chips are generated by the ampoule bottle in the breakoff process, and the glass chips directionally flow towards the outer portion of the ampoule bottle to be collected by the chip removing mechanism and cannot fall into the ampoule bottle. After breakoff of the ampoule bottle is finished, the ampoule bottle is inflated with sterile nitrogen, medicines are free of pollution, and a broken-off bottle head is automatically recycled. According to the sterile opening method and device, the process of clamping, sawing, chip removing, cleaning, disinfecting, breakoff and gas inflation is automatically completed, manual operation is not needed, and operation damage is avoided; liquid gas spraying disinfecting is carried out, and pollution of scrubbing absorbent cotton residues on medicines is avoided. Full-automatic control, safety, reliability and environment protection are achieved.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a method and device for aseptically opening a medical ampoule bottle. Background technique [0002] Ampoule bottle is a small bottle made of sealed high-quality thin glass, which is often used to store medicines for injection, vaccines, serum and other drugs, and is also used for packaging of oral liquids. The capacity is generally 1-25ml. Glass ampoules are stable in nature, not easy to react with drugs, have good barrier properties, can effectively isolate the penetration of air and moisture, and have good light transmission and high temperature resistance, so they are widely used in the medical industry. To touch the ampoule, it is necessary to break it and use the medicine in the ampoule. [0003] At present, there are mainly two methods for breaking ampoules: manual breaking and mechanical breaking. When manual breaking is used, due to the brittleness of the ampoule glass,...

Problems solved by technology

When manual breaking is used, due to the brittleness of the ampoule glass, the glass ampoule bottle is easily broken during the opening process, resulting in injuries to medical personnel. 100% of sharp injuries occurred in 2018, 94.49% of those with junior professional titles, and 93.75% of pharmacy personnel, which made it difficult for the medical and nursing personnel to devote themselves to their work with great work pressure and psychological pressure

Although the use of mechanical devices for breaking can improve the working conditions of breaking and reduce the probability of sharp injuries to medical staff, but many non-directional glass fragments generated during the breaking process will contaminate the medicine in the ampoule

[0004] Regardless of manual breaking or mechanical breaking, due to the need for heating in the process of manufacturing the ampoule, the ampoule is under negative pressure at room temperature, and many non-directional glass fragments will be generated at the fracture at the moment of opening the ampoule , easily sucked into the ampoule by negative pressure; these glass fragments are insoluble in liquid, if they enter the ampoule and enter the human body with the drug, they will cause harm to the human body, such as subcutaneous injection will cause nodules, and intravenous injection may cause blood vessel obstruction , infusion reaction and phlebitis, local granuloma, pulmonary hypertension, etc.
