Scald apparatus using arc lamp as light source

Abstract

The invention discloses a scald apparatus using an arc lamp as a light source, which is characterized by comprising a black box with a light emergent hole, wherein, the arc lamp, a convex lens, a concave lens and a light insulation plate are arranged on the light axis passing through the center of the light emergent hole in the black box from far to near; the arc lamp is arranged on the focus of aparaboloidal concave lens; the light emitted by the arc lamp becomes parallel light by the reflecting of the paraboloidal concave lens, enters from one side of the convex lens and converges at the focus F at the other side of the arc lamp; the converged light becomes parallel glowing light spots by the concave lens arranged outside the focus F, and finally passes through an aperture of a light passing axis on the light insulation plate to be projected by the light emergent hole of the black box; the concave lens can be adjusted between the focus F and a point 2F which is two times of the focal length of the convex lens; a photoswitch device for connecting a timer is arranged between the outside of the aperture of the light insulation plate and the light emergent hole of the black box; andthe inner side of the aperture of the light insulation plate is provided with a temperature probe for connecting a temperature display.

Description

technical field [0001] The invention relates to a burn and scald device in medical experiments, in particular to a burn instrument using an arc lamp as a burn light source. Background technique [0002] Burns generally refer to heat, including hot liquid (water, soup, oil, etc.), high-temperature gas, hot solid, flame, etc. The tissue damage caused by it mainly refers to the skin and / or mucous membrane, and in severe cases, it can also injure the subcutaneous tissue. or / and submucosal tissue. Burns and scalds bring great harm to the injured every year, not only bring physical trauma, but also may bring mental stress. With the emergence of a large number of various heating devices and instruments, the prevalence of burns and scalds is on the rise. . Therefore, the research on burns and scalds is also extremely important. The study of burns is inseparable from the production of animal burn models, and the quality of the burn model directly affects the evaluation and identif...

Problems solved by technology

The above-mentioned methods have the following disadvantages to varying degrees, such as inaccurate temperature control, inaccurate and consistent injury area, and poor time control, etc., which easily lead to differences in the modeling of the experiment, which eventually leads to bias in the experimental results

The current scald instruments on the market are expensive and complex in structure, and often cannot achieve precise control of temperature and scald area
