RU79701U1 - DEVICE FOR MODELING A WOUNDED SURFACE OF SPECIFIED DIMENSIONS IN LABORATORY ANIMALS - Google Patents

Abstract

The invention relates to experimental medicine and is intended to conduct experiments on the skin of laboratory animals. The technical result is the creation of a device that allows you to simply and quickly simulate a wound of a given size. The essence of the invention lies in the fact that the device for modeling the wound surface in laboratory animals includes a handle and a special platform that determines the size of the wound, as well as four metal rods, the pointed ends of which, when forming a wound defect, penetrate the skin and tightly fix to it a device, after applying which, a scalpel is circled around the edge of the platform, thereby cutting out the necessary area. Subsequently, the punctured skin sites are removed along with the reduced skin flap. (Fig. 3)

Description

The invention relates to experimental medicine and is intended to conduct experiments on the skin of laboratory animals.

Closest to the claimed solution is a device for experimental modeling of skin wounds, proposed by A.A. Vorobyev et al. (application for invention No. 41908 dated 02.04.2004).

The technical result is the creation of a device that allows you to simply and quickly simulate a wound of a given size.

The essence of the invention lies in the fact that the device for modeling the wound surface in laboratory animals includes a handle and a special platform that determines the size of the wound, as well as four metal rods, the pointed ends of which, when forming a wound defect, penetrate the skin and tightly fix to it a device, after applying which, a scalpel is circled around the edge of the platform, thereby cutting out the necessary area. Subsequently, the punctured skin sites are removed along with the reduced skin flap.

The invention is illustrated by the figures:

Figure 1 shows a device for modeling the wound surface, General view.

Figure 2 is a device for modeling the wound surface, view from below and side.

Figure 3 - stitching stitching metal rods of the site.

The device consists of a handle - 1, a rubber pad - 2 (see figure 1, 2) and metal rods - 3 (see figure 3) located inside them.

The handle - 1, made in the form of a cone-shaped cylinder having a length of 100 mm, an upper diameter of 20 mm, a lower diameter of 15 mm. Inside

4 metal rods are enclosed in the handle (see FIG. 3), the pointed ends of which extend from the side of the smallest diameter of the handle by 8 mm.

The rubber pad - 2 (see figure 1, 2), which determines the size of the wound surface, has a thickness of 5 mm and when working, it is mounted on metal rods until it stops completely against the handle.

Metal rods - 3 (see figure 3), in the amount of 4 pcs., With a diameter of 1 mm. their location form a square with a side of 8 mm. and are designed to tightly fix the device to the skin.

Thus, the proposed device differs from similar ones in that it consists of a handle, a rubber pad and four metal rods passing through them, allowing the device to be firmly fixed to the skin of the animal, thereby preventing displacement and minimizing errors in operation.

Thus, the proposed device helps to solve a number of problems:

1. To simplify and accelerate the process of modeling the wound surface in laboratory animals.

2. Allow to form under experimental conditions a wound surface of clearly standardized sizes.

Claims (1)

A device for modeling the wound surface of a given size in laboratory animals, characterized in that it includes a handle and a rubber pad that determines the size of the wound surface, as well as four metal rods with pointed ends, which allow the device to be tightly fixed to the skin when forming a wound defect and prevent its displacement.
