Description

Technical Field

[0001] The utility model relates to the field of medical devices, and particularly relates to an ampoule opening device for intensive care. Background Art

[0002] Patients in the intensive care unit need to obtain nutrients or elements to maintain their body functions through intravenous infusion or infusion pump. Some substances need to be stored in ampoules and refrigerated to maintain their corresponding functions. When medical staff in the intensive care unit add corresponding drugs or special nutritional components to the infused liquid medicine, they need to open the ampoule to suck the corresponding liquid medicine. Currently, medical staff mainly break the neck of the ampoule by finger or use nursing supplies such as tweezers and hemostats to knock the neck of the ampoule to open the bottle. Since the ampoule is made of glass, glass shards will be generated when the ampoule is broken or knocked. If the glass shards are not properly handled, they will cut the fingers of medical staff and enter the liquid medicine, or even scatter on the ground and cause harm to other people.

[0003] The grinding wheel can effectively cut the ampoule. Currently, medical staff hold the ampoule with one hand and hold the grinding wheel with the other hand and rotate it 360° along the neck of the ampoule to cut it, thus opening the ampoule. This method can effectively reduce the generation of glass shards. The currently used ampoule opening device with a grinding wheel has the following problems in use: 1. When using the grinding wheel to cut the neck of the ampoule, the neck of the ampoule lacks corresponding support, resulting in difficulty for the grinding wheel to effectively apply the cutting force, causing the problem of multiple cuts and low ampoule opening efficiency; 2. Since there are many specifications and models of ampoules, the ampoules have multiple neck openings with different outer diameters. The current opening device arranges multiple ampoule neck insertion openings with different apertures on the handle. These ampoule neck insertion openings are separated from the grinding wheel cut, and it is impossible to quickly switch different arc chucks to hold ampoules with different sizes of necks while applying the cutting force through the grinding wheel; 3. The current wrench-shaped handle is not convenient for rotating and cutting operations when holding the ampoule. Content of the Utility Model
