Closed self-circulation burn wound cooling and drying device

Abstract

A closed self-circulation burn wound cooling and drying device comprises a transparent cover, an air return pipe, an air blowing pipe, a sealing ring and an elastic bandage which are arranged outsidea shell, and further comprises a sterilization device, a cooler, a dehumidifier, a fan, cooling fins, a power supply controller, a connecting pipe, a fan and an activated carbon adsorption box which are arranged in the shell. The transparent cover is sequentially connected with the air return pipe, the sterilization device, the cooler, the dehumidifier, the connecting pipe, the fan, the activatedcarbon adsorption box and the air blowing pipe, and the tail end of the air blowing pipe is connected back to the transparent cover to form a closed air self-circulation cooling and drying channel. The closed self-circulation burn wound cooling and drying device is low in use cost, wide in application range and bright in application prospect. When a power supply is connected, the temperature, humidity and wind speed of air in a closed self-circulation system can be adjusted. Dressing and medicine are not used, ice species do not need to be frequently added or ice bags do not need to be frequently replaced, use is easy and convenient, and comprehensive benefits are obvious.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a closed self-circulation burn wound cooling and drying device. Background technique [0002] In the medical field, when a patient is subjected to local burns or scalds, the wound is painful and prone to exudate and infection. When using cold compresses such as ice packs, the ice packs condense the water vapor in the air to form water droplets, and the water droplets are more likely to be infected when they come into contact with the wound. Use a dressing to cool down the wound. Because the dressing directly contacts the wound, the exudate will soak the dressing quickly, and the wound cannot be kept dry, which may easily cause inflammation, or the dressing will adhere to the wound. Therefore, there is a need for a device that can continuously cool down and dry the wound without touching the wound, isolate bacteria and dust in the ambient air, reduce the exudate of the wound, and...

AI Technical Summary

Problems solved by technology

[0003] Judging from the relevant patents published so far, it mainly uses ice types, sea water, hydrogel, cooling compounds, etc., and uses physical contact with the wound to cool down, and its disadvantages are obvious.

There is also the use of ice-water mixture to push the external air through the fan to flow to the wound after heat exchange and cooling. This solution does not sterilize the air flowing to the wound, which may infect the wound. The effect of moisture in the air is poor, the ice-water mixture needs to be replaced, the device is bulky, and it is inconvenient to move when installed on the body

[0004] In a large number of equipment solutions for wound treatment, there is no dry treatment of the wound at the same time

However, the negative pressure wound treatment equipment for dry treatment of wounds does not have the function of cooling

There is no wound treatment equipment for cooling, drying, and isolating burn wounds from the external environment at the same time. Cooling, drying, and avoiding external bacterial infection are important factors to promote wound healing
