Medical temperature-adjustment pressure-adjustment instrument for small-area burn

Abstract

The invention discloses a medical small-area burn instrument for adjusting temperature and pressure, which comprises an animal fixing device, a burn device, a pedestal, a clamper and an elastometer. The burn device is fixed on the clamper, the pedestal is fixedly provided with a pull rod, the clamp is arranged on the pull rod in an axial sliding mode, one end of the elastometer is fixed oppositely to the pedestal and the other end of the elastometer is axially and fixedly connected with the back end of the clamper, the burn device is an electric heating burn device and comprises a burn head and an electric heater, and the electric heater is connected with an electric source through a temperature control device. The medical small-area burn instrument has the advantages that the medical small-area burn instrument has objective pressure display by adopting a pressure indicating device and a temperature adjusting device, can adjust pressure, temperature and burn area, and can adjust burn temperature, burn pressure and area according to the test requirements to make a standardized burn wound surface.

Description

Technical field [0001] The invention relates to a wound-causing device for burn animal models, in particular to a medical temperature and pressure regulator for small area burns. Background technique [0002] Burns are a common and important trauma in daily life. Strengthening the clinical treatment and pathogenesis of burns and improving the level of burn treatment have important social and military significance. In the basic and applied research in the field of modern burn surgery, the establishment of a burn animal model is an extremely important experimental method and means. The ideal burn model will help to more scientifically and accurately understand the development of various body systems and local wounds after burns. The law of evolution, exploring targeted prevention measures. [0003] In the burn research of the prior art, different methods are used to make burn models, such as: bromine tungsten lamp radiation, flash powder chemical burn, napalm burn, hot water burn, ...

AI Technical Summary

Problems solved by technology

[0005] 1. The manufactured device is complex, its area and depth are not easy to control, and the wounding steps are relatively cumbersome. There is a possibility of damaging the uninjured area, and the repeatability is poor, which brings great difficulties to the production of standardized burn wounds and affects the burn. Research result;

[0006] 2. In some methods, the injury temperature is single, about 100°C, and the hot head is pressed manually to injure the skin, and the pressure cannot be guaranteed to be consistent every time;

[0007] 3. In some methods, the depth of the burn wound may be inconsistent due to the uneven coating of the fuel and the failure to extinguish the fire at one time; the wound may be polluted during fire extinguishing;

[0008] 4. Some methods are affected by factors such as whether the voltage is constant, whether the area to be burned is flat, and the body position of the experimental animal is changed under a non-anesthetized state, so the depth of the wound may vary;

[0009] 5. The method in the prior art has no objective pressure display, no instructions during operation, and cannot effectively control the depth and degree of burns
