Abstract
The invention relates to a medical transfusion switch, which belongs to the technical field of medical equipment and comprises a switch body and a poking handle, wherein the switch body comprises a switch sleeve, a liquid inlet joint and a liquid outlet joint, the switch sleeve is provided with a cavity, the cavity is provided with a liquid inlet hole and a liquid outlet hole, the liquid inlet joint is directly formed on the switch sleeve and is corresponding to the liquid inlet hole, the liquid outlet joint is directly formed on the switch sleeve and is corresponding to the liquid outlet hole, the poking handle is matched with the switch sleeve in a rotating mode, and the poking handle is provided with an arc-shaped sealing plate. The medical transfusion switch is characterized in that an arc-shaped supporting plate is arranged in the cavity and in the position corresponding to the liquid inlet hole, the arc-shaped supporting plate is formed on the bottom plate of the cavity, a sealing plate rotating groove is maintained above the arc-shaped supporting plate, the arc-shaped sealing plate is matched with the sealing plate rotating groove, a central line of the liquid inlet joint and an axial central line of the cavity are not in the same plane, one side of the poking handle, which faces the switch sleeve, is provided with a poking handle pivoting groove, and the poking handle pivoting groove is matched with the switch sleeve.
Description
Technical field [0001] The invention is a medical equipment technology field, which involves a medical infusion switch. Background technique [0002] As known in the industry, there are usually two types of infusion switches on the infusion pipeline, and the structure of the infusion switch is roughly two: one is to push the block or pressure wheel structure. This switch is easy to swim under slight touch;Second, a handlebar infusion switch with a 90 ° rotation angle angle, this infusion switch will not change due to slight touch, but in the actual use process, it is still exposed, especially at night, the patient itself or the accompanying staffFailure to transfer the switch to 90 °, then the infusion pipe is broken, that is, no liquid.In addition, for those who are weak, such as chronic diseases, people with disabilities, etc. Due to their physical strength, it is often difficult to transfer the degree of correctly to 90 °. [0003] In the book, it is necessary to improve the s...
