Description

Touch Screen Washer Based on Embedded System

technical field

The invention relates to a washer, in particular to a touch screen washer based on an embedded system.

Background technique

Infection rates after surgical procedures have a lot to do with the amount of tissue debris remaining at the surgical site. For some important surgical operations, such as thoracic surgery, spinal cord surgery, etc., whether the tissue debris generated during the operation can be removed cleanly and effectively will directly affect the postoperative recovery of the patient, and even endanger the life of the patient in severe cases.

Although many surgeons have recognized the importance of this problem, they cannot solve it due to the ineffectiveness of traditional irrigation methods. The traditional method of rinsing the surgical site is that the nurse pours physiological saline into a porcelain dish, and then the doctor holds the porcelain dish containing physiological saline and pours it into the surgical site. This cumbersome process itself is easy to introduce bacteria; in addition, due to The liquid flow rate is limited, and the flushing angle cannot be controlled, so the flushing effect is not ideal, and some dead angles are not easy to flush.

At present, various types of washing appliances have been developed in the market, but the operation is mostly based on buttons and LED displays. If the touch screen is used instead, the equipment will be more humanized, and the operation and display information will be richer and more flexible, which is greatly convenient. The medical staff cleaned up the patient's wound in time to buy more precious time for the operation.
