Abstract

The invention relates to the field of medicine, namely to the preclinical diagnosis of occupational skin diseases. The aim of the invention is to improve the accuracy of determination. A device for determining skin resistance to alkali is made of a transparent base 1 and is equipped with a diagnostic chamber 2 with a safety shoulder 3 and a through channel 4 in the center. For hermetic fixation, the device is equipped with eyelets 5 to the skin, to which, by means of hooks 6, a bracelet is attached, fitted with a lock like a contact tape. 2 Il.

The invention relates to medicine, in particular to the diagnosis of occupational skin diseases.

The aim of the invention is to reduce the detection time.

FIG. 1 shows a device for determining skin resistant to alkali ™, top view; figure 2 is the same, side view.

The device is made in the form of bases 1 made of transparent polished organic glass with a diagnostic chamber 2 in the center, equipped with a safety raised shoulder 3, which ensures the tightness of the chamber and does not allow an alkali solution to flow. In the center of the chamber 2 there is a through channel 4 with a diameter of 2 ml to inject alkali with a pipette into the cavity of chamber 2, which is sealed with the skin of the subject.

The eyelets 5, with the help of hooks 6, attach the fastening means in the form of bracelets 7, fitted with a lock of the type of contact tape 8, with which the density of the device can be easily fixed to the skin without additional adjustment of the bracelet length.

The device is used as follows.

For the preclinical diagnosis of allergodermatosis, under conditions of production, a device for determining alkali resistance of the skin is fixed on the workplace to the previously cleaned skin of the patient’s forearm with the help of bracelet 7.

Using a pipette, a drop of alkali is introduced through the channel 4 into the diagnostic chamber 2. After 10 minutes, without removing the device, the nature of the inflammatory response is visually determined.

In the absence of the latter, a drop of alkali is introduced into the chamber twice more with an interval of 10 minutes.

This device, used in production conditions, makes it possible to diagnose preclinical forms of occupational skin diseases directly in the workplace shop.

Moreover, during testing, the subject does not experience any inconvenience and continues to perform his functional duties, which leads to a saving of 30 minutes of working time.

Claims (1)

1. A device for determining the resistance of the skin to alkali, containing a transparent base with a working surface, which is due to the fact that, in order to reduce the determination time, a rectangular recess with safety flanks located along the perimeter of the recess is made on the working surface of the base; the opposite side of the base is made through a channel that communicates with the cavity of the recess for the introduction of an alkali solution, 2, the device according to claim 1, characterized in that, in order to ensure reliable fixation of the base to the skin surface, the fixation means in the form of a bracelet with a lock are made on the sides of the base. / / Proofreader T.Paly
