Clinical instrument cleaning device for digestive system department

Abstract

The invention discloses a clinical instrument cleaning device for the digestive system department, and relates to the technical field of medical instruments. The device comprises a cleaning box, wherein, the upper end of the cleaning box is sleeved with a sealing cover; a bubble generating unit is arranged at the bottom end in the cleaning box; a supporting net plate is arranged above the bubble generating unit; the supporting net plate is correspondingly sleeved and fixed to the lower side in the cleaning box. micro-nano through holes are uniformly distributed in the supporting net plate; the bottom end of the cleaning box fixedly communicates with a liquid inlet pipe and an air inlet pipe; a mounting through hole is formed in the left lower part of the cleaning box; an elastic film is embedded and fixed in the mounting through hole in a matched manner; an ultrasonic vibrator is fixed on the outer side of the elastic film; an electrostatic generator is fixed to the right side of the cleaning box; and the output end of the electrostatic generator hermetically penetrates into the lower side of the cleaning box. The device has the beneficial effects that micro-nano bubbles can be generated, the situation of mutual polymerization of the micro-nano bubbles can be effectively reduced, and the cleaning effect on medical instruments is guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical instruments. Background technique [0002] Micro-nano bubbles refer to bubbles with diameters ranging from tens of microns to hundreds of nanometers when bubbles occur. This kind of bubbles has physical and chemical characteristics that conventional bubbles do not have. If the specific surface area is large, in the case of the same total volume of the gas, the contact area between the micro-nano bubbles and the liquid is large; in addition, the volume of the micro-nano bubbles is small, the rising speed in the liquid is slow, and the residence time is long; moreover, the specific surface area of ​​the micro-nano bubbles Large, the surface tension effect is strong, the internal pressure is large, and the internal pressure will increase as it is compressed, and the dissolution rate will increase. Therefore, the micro-nano bubbles have a strong gas dissolving ability and a high gas dissolution rate; ...

AI Technical Summary

Problems solved by technology

However, a large number of micro-nano bubbles are easy to contact each other in the liquid to aggregate, and the volume of the micro-nano bubbles increases after polymerization. Once the micro-nano bubbles exceed the range of micro-nano, the effect of the micro-nano bubbles will disappear.

However, the traditional micro-nano bubble generator does not take into account the problem that the bubbles are easy to aggregate with each other, so when generating micro-nano bubbles, many bubbles beyond the micro-nano range will be doped due to the polymerization problem, resulting in the effect of generating micro-nano bubbles Poor, affecting the cleaning effect of medical equipment
