Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings, but not as any limitation to the present invention.

[0016] The principle of the present invention is to evaluate the burn depth of the wound by detecting the different thermal radiation of the burned skin. The method is to use two symmetrical halogen lamps as external heat sources, and project them on the burn wound at a symmetrical angle. When the temperature reaches Tmax, then a halogen lamp is applied to cool the wound surface naturally to To, and at the same time, an infrared camera is used to record the thermal time constant t of each point on the wound surface in the vertical direction of the wound surface (t is the time from Tmax to To), and finally use t The value evaluates the burn depth of the wound surface, and transmits the images and data to the monitor and memory card.

Abstract

The invention discloses a pressure sore depth detector. The pressure sore depth detector comprises a shell; the bottom of the shell is provided with an infrared receptor probe; the front of the shell is provided with a switch button and a start / pause button respectively; the back of the shell is provided with a back cover into which a lithium battery and a memory card can be arranged; the upper end of the shell is provided with a display capable of displaying local depth data in real time, and is provided with a USB (universal serial bus) interface corresponding to the display in position. The pressure sore depth detector is simple in structure and convenient to operate, can accurately detect pressure sore damaged depth and is obvious in effect and high in economic and social benefits.

Description

technical field [0001] The invention relates to a pressure sore depth detector, which belongs to the field of medical equipment. Background technique [0002] A pressure sore is a localized injury to the skin and / or subcutaneous tissue, usually over a bony prominence. This kind of injury is generally caused by pressure or pressure combined with shear force. When it is compressed for a long time and concentrated on a certain part of the body, it is enough to block the local blood circulation and cause tissue hypoxia, thereby causing tissue damage and necrosis. If sustained pressure will lead to full-thickness skin necrosis defects. The resulting ulcers are likely to lead to bacterial infection. Due to the congestion of capillaries and veins at the base and edge of the ulcer, and the gradual formation of a large amount of granulation tissue, the ulcer or gangrene area can be penetrated and expanded rapidly under the skin. The diameter can reach 3-6 cm within a few days. It c...
