CN2141260Y - Portable burn skin quantitative observation instrument - Google Patents

Abstract

The utility model is a portable burn skin island quantitative observation instrument composed of a magnifying glass (including two cylinders with different diameters and a single-sided convex mirror on the two ports, a square hole flat film with scale marks) and a handle with a light source. It provides scientific basis and convenient and practical equipment for burn doctors to observe the regeneration of wound epithelial cells, determine its treatment plan, and judge prognosis. It is also an indispensable tool for dermatologists to observe skin lesions and diagnose skin diseases.

Description

The utility model belongs to medical instruments and relates to a special instrument for observing the regeneration of wound epithelial cells during the treatment of burns.

After deep second-degree and third-degree superficial burns on human skin, "moist exposure therapy" is used to treat the wound surface. Under normal circumstances, necrotic tissue is liquefied and removed layer by layer, and epithelial cells of the remaining skin appendages are regenerated, glandular granules appear, and skin islands are formed. Fusion with each other into pieces and then cover the wound and heal slowly. Knowing the number of glandular granules, number of skin islands and their expansion during the treatment will provide a scientific basis for judging the prognosis of the patient, whether skin grafting is needed, the course of treatment, etc., increasing the doctor's understanding of the burn condition, and determining further treatment plans and effective measures. In the past, doctors relied solely on their clinical experience. For doctors with insufficient clinical experience, treatment was often delayed due to misjudgment. Therefore, a certain amount of observation equipment is urgently needed.

In order to solve the above problems, the purpose of this utility model is to design an observation mirror with magnification and measurement functions, and a burn skin island observer with its own light source and easy to carry, so that the diagnosis and treatment of burn diseases have a scientific basis and the measures are more appropriate. The curative effect is more ideal.

The utility model comprises a magnifying glass and a handle with light source two parts (as shown in Figure 1), the magnifying glass is made up of cylinder 1 and lens 3, flat plate 4 that are contained on two ports. 1 is a cylinder made of metal or hard plastic with a length of 4-6cm and two ports with different diameters. The diameter of the upper port is 4-5cm, and a transparent (made of organic glass or transparent plastic) with a square hole in the center ) flat piece 4, and fix it on the upper mouth with a spiral fixing ring 5. The diameter of the lower port of 1 is 2～3cm, and a single-sided convex lens 3 with a convex surface is fixed on the lower port with a helical fixing ring 6; a round hole in the side of the middle section of 1 communicates with the hollow handle. The handle 2 is a cylindrical shape made of metal or hard plastic (the same as the existing ordinary flashlight except the light-transmitting cover), with a DC power supply inside and a switch outside, and a small light bulb at the connection between the hollow handle at the proximal end and 1 , There is a screw cap at the end of the handle, and the battery can be installed and removed by opening the screw cap.

In addition, one side of the square hole of the transparent flat sheet 4 is provided with a metric length scale, the other side is provided with a coordinate scale, and the other side is provided with a grid-shaped scale mark, which are respectively used to measure the distance, orientation and certain range of the observed part. The number of endothelial islands and glandular granules.

When the utility model is in use, if the condition of the wound surface is observed, the convex lens 3 (small opening) can be placed on the wound surface as a magnifying glass, and its magnification can adjust the distance between the mirror surface and the wound surface or exchange lenses of different multiples through the spiral fixing ring. If it is necessary to measure the dispersion degree of glandular particles, skin island quantification and diffusion, the square hole plain film can be placed downward (placed on the wound surface), the power is turned on and the near-convex lens end is made with a single eye, and the scale marked on the square hole plain film can be observed and passed Calculate their number and distribution.

The utility model fully achieves the design purpose through trial use, and is not only a convenient and practical tool that medical workers in the burn department can carry with them, but also a convenient and practical tool for dermatologists to observe skin diseases (skin rashes).

Accompanying drawing 1 is the appearance schematic diagram of the utility model. Among them, 1-magnifying glass cylinder, 2-handle, 3-single-sided convex lens, 4-square hole flat film, 5-flat film fixing ring, 6-helical fixing ring.

Accompanying drawing 2 is the schematic diagram of square hole plain film of the present utility model. Among them, 7-length scale, 8-mesh scale, 9-coordinate scale, 10-square hole.
