Automatic wound washing device

Abstract

The invention discloses an automatic wound irrigation device. The automatic wound irrigation device comprises an irrigation pipe and a guide pipe, and the inlet end of the irrigation pipe is communicated with the outlet of a water supply container; the inside of the water supply container is provided with a pressurizing device; the outlet end of the irrigation pipe is arranged inside a wound, normal saline can flow out of the outlet end of the irrigation pipe into the wound to form a liquid flow environment as well as maintain a preset liquid pressure inside the wound, and accordingly a high-pressure area can be formed; the inlet end of the guide pipe is arranged inside the wound, and the outlet end of the guide pipe is communicated with a recovery container, inside which a negative-pressure device is arranged for forming a vacuum environment inside the recovery container; the vacuum environment inside the recovery container can form a low-pressure area inside the wound via the inlet end of the guide pipe; the normal saline flowing out of the outlet end of the irrigation pipe flows from the high-pressure area to the low-pressure area and meanwhile irrigates the wound; drainage liquid formed after wound irrigation can enter into the inlet end of the guide pipe and flow into the recovery container via the outlet end of the guide pipe.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to an automatic wound washing device. Background technique [0002] In the prior art, in order to avoid postoperative infection and promote wound healing, it is necessary to wash the wound and guide the blood or other fluids from the wound to the outside of the body. The traditional flushing method is to flush the wound by dripping. Due to the low pressure of the flushing liquid, this cleaning method can easily lead to the inability to guide the hemorrhage in the wound, and cannot form a liquid flow environment, forming hematoma and blood clots in the patient's body. It will compress the nerve and cause safety hazard to the patient. Contents of the invention [0003] In order to solve the above technical problems, the present invention proposes an automatic wound flushing device, which uses two pipes, a flushing tube and a guide tube, to form a liquid flow environment. Th...
