Quantitative liquid adding device for full-automatic medical cleaner and control method thereof

Abstract

The invention provides a quantitative liquid adding device for a full-automatic medical cleaner, which comprises a liquid medicine input part, a liquid medicine mixing chamber, an exhaust part, a pure water input part, a liquid medicine output part and a control system, wherein the liquid medicine input part is connected with an external liquid medicine storing container; the liquid medicine output part is used for discharging liquid medicine; and the control system is electrically connected with all parts. The quantitative liquid adding device is characterized by also comprising a peristaltic pump which is arranged between the liquid medicine input part and the liquid medicine mixing chamber, the peristaltic pump is electrically connected with the control system to quantitatively convey the liquid medicine in the external liquid medicine storing container to the liquid medicine mixing chamber. The invention also provides a control method of the quantitative liquid adding device. As the peristaltic pump driven by electric power is used for adding liquid, firstly, without additionally adding external high-pressure gas to drive the liquid medicine to enter the mixing chamber from the storing container, the quantitative liquid adding device effectively prevents the problems of liquid medicine scattering and the like caused by air pressure variation; and secondly, as the peristaltic pump can accurately control the added quantity of the liquid medicine per se, the whole quantitative liquid adding device has simpler structure and accurate added quantity of the liquid medicine and is easier to control.

Description

technical field [0001] The invention belongs to the field of medical equipment, and relates to a fully automatic medical cleaning machine, in particular to a quantitative liquid adding device and a control method for the fully automatic medical cleaning machine. Background technique [0002] Surgical instruments used for the purpose of treatment in the human body, after entering different human bodies, have different blood, body fluids and other dirt on the surface. In order to ensure life safety, before using the above surgical instruments next time, they must be cleaned It is fully and thoroughly cleaned and disinfected. [0003] In the process of fully and thoroughly cleaning and disinfecting surgical instruments, the problem of filling the cleaning and disinfecting liquid must be involved. At present, on the problem of liquid medicine filling, the purpose of controlling the flow is mainly achieved through fluid control valves, sensors, solenoid valves, flow meters, etc....

AI Technical Summary

Problems solved by technology

Although this solution solves the problem of preventing splashing of the liquid medicine when the amount of liquid medicine added is insufficient, it still uses an external high-pressure gas to drive the liquid medicine injection, and the structure and procedures are more complicated and the cost is higher.
