STEPLESS SPEED REGULATION MEDICAL PULSE IRRIGATOR WITH LED LAMP

Abstract

Disclosed is a disposable stepless speed regulation medical pulse irrigator with an LED lamp, including an upper handle, a lower handle, a pump body, a fluid tube, stepless speed regulation control parts, a spray nozzle part, a power supply part and an LED lamp. The pump body is arranged inside the upper handle; the left side of the pump body is connected with a piston; and the bottom end of the piston is provided with a big gear. In a pulse irrigating process of a wound, the disposable stepless speed regulation medical pulse irrigator with the LED lamp can use a continuous regulatable flushing speed and pressure to reduce the discomfort of a patient with this instrument according to the wound pain sensitivity of the patient, and can improve the wound cleansing efficiency and relieve the working load of medical staff at the same time. When flushing fluid splashes onto a contaminated fluid collection bag to obstruct the field of view, the LED lamp can be turned on through an LED lamp control switch to assist in the observation for the wound, which facilitates debridement personnel to determine whether debridement is completed, so that the debridement time and cost are greatly saved.
