Description

Technical Field

[0001] The utility model relates to the field of debridement devices, in particular to an oxygen-driven water-powered debridement device. Background Art

[0002] The oxygen-driven hydrodynamic debridement device is a device used in the medical field. It is mainly used as a tool for cleaning and treating wounds. It adopts the principle of mixed injection of oxygen and water, and uses high-speed oxygen and water flow to impact the wound, thereby achieving the effect of cleaning, decontamination and promoting wound healing.

[0003] When the existing hydrodynamic debriders are used to clean and decontaminate the wound surface, the injection pressure of most water flows is relatively low, and thus the wound surface cannot be effectively cleaned and decontaminated. In addition, when most of the existing hydrodynamic debriders are used to adjust the water flow pressure, most of them cannot adjust the power of the liquid supply equipment and the air supply equipment, which is relatively troublesome. Therefore, technical improvements are urgently needed. Utility Model Content

[0008] Furthermore, a flushing hole is provided on the inner bottom surface of the cleaning head;

[0009] Through the above technical solution, the flushing hole is opened through the inner bottom surface of the cleaning head, so that the wound surface can be flushed better and the pressure of the jet water flow can be further enhanced.

[0010] Furthermore, the lower end of the flushing pipe body passes through the interior of the handle cleaning head;

[0011] Through the above technical solution, the lower end of the flushing tube body penetrates the interior of the handle cleaning head, so that the physiological saline can be directly transported to the interior of the cleaning head in a better manner.

[0012] Furthermore, the lower end of the oxygen tube is connected to the storage chamber;

[0013] Through the above technical solution, the lower end of the oxygen tube is connected to the storage cavity, so that oxygen can be better transported to the interior of the storage cavity for storage.

[0014] Furthermore, both ends of the current limiting roller slide inside the chute;

[0015] Through the above technical solution, both ends of the flow-limiting roller slide inside the slide groove, so that the flow-limiting roller can better limit the flow of the medium inside the flushing tube or the oxygen tube.

[0016] Furthermore, the outer walls of the current limiting rollers are provided with rubber pads;

[0017] Through the above technical solution, rubber pads are provided on the outer walls of the current limiting rollers, so that the current limiting rollers can be rotated better.

[0018] Furthermore, the inner walls of the fixing grooves are provided with sponge pads, and the inner walls of the sponge pads are closely fitted with the flushing tube and the oxygen tube respectively;

[0019] Through the above technical solution, sponge pads are provided on the inner walls of the fixing grooves, and the inner walls of the sponge pads are tightly fitted with the flushing pipe and the oxygen pipe respectively, thereby effectively preventing the inner walls of the fixing grooves from damaging the flushing pipe or the oxygen pipe.

[0021] Through the above technical solution, the anti-slip texture is provided on the outer wall of the handle, thereby effectively improving the anti-slip performance of the handle.

[0022] The utility model has the following beneficial effects:

[0023] 1. The utility model proposes an oxygen-driven hydrodynamic debridement. Compared with the existing debridement, the debridement uses a cleaning head to transport physiological saline to the inside of the cleaning head through a flushing tube, and then transports oxygen to the inside of the storage chamber through an oxygen tube, and then allows oxygen to enter the inside of the cleaning head through a one-way valve, and then increases the pressure inside the cleaning head, so that physiological saline is sprayed out through the flushing hole, thereby cleaning and flushing the wound surface, thereby effectively increasing the pressure of the sprayed water flow.

[0024] 2. The utility model proposes an oxygen-driven hydrodynamic debridement. Compared with the existing debridements, the debridement has a flow limiting box. When it is necessary to adjust the flow of physiological saline in the flushing tube or the oxygen in the oxygen tube, the flow limiting roller can be rolled to slide inside the slide groove, so that the flow limiting roller squeezes the flushing tube or the oxygen tube, thereby slowing down the flow of the medium inside the flushing tube or the oxygen tube.
