The device according to claim 1, characterized in that the weight of the device is 250 g, the length of the housing is 100-150 mm, the diameter of the housing is 20-30 mm.

Description

The utility model relates to medical equipment, and more specifically to devices used to diagnose sensitivity disorders, for example, with a vibrational disease.

A device for assessing sensitive adaptation, containing a cylindrical body, an impact mechanism with a needle and a tripod with supporting elements (1).

The disadvantage of this device is the increased complexity of the design and inconvenience of use.

Known measuring device comprising a housing with a movement indicator and a measuring probe (2).

The disadvantage of this device is the lack of accuracy of the measurement results.

A device for determining tissue compliance is known, comprising a housing, a displacement indicator, a measuring probe with a support bell provided with a sealing ring (3).

The disadvantage of this device is the lack of accuracy of the measurement results.

A device for determining pain sensitivity of the skin, containing an indicator with a head mounted on a spring-loaded bracket located on a tripod with stand (4).

The disadvantage of this device is the design complexity, inconvenience of use and insufficient measurement accuracy.

A device for the study of dermographism is also known, containing a cylindrical body with a scale and a pointer and a spring action mechanism provided with a needle (5).

The disadvantage of this device is the design complexity, inconvenience of use and insufficient accuracy of the measurement results in the diagnosis of vibration disease.

The purpose of creating a utility model is to simplify the design, improve ease of use and improve the accuracy of determination results in the diagnosis of vibration disease.

This goal is achieved by the fact that the body is made in the form of a cylinder with a screw thread on the distal end with a regulating nut fitted with a pointer arrow, and the acting needle is installed on the distal end of the body, and the device weighs 250 grams, the body length is 100- 150 mm, the case diameter is 20-30 mm.

Comparison of the proposed device with other well-known in the field of medicine showed its compliance with the criteria of a utility model.

The utility model is accompanied by graphic material that depicts the proposed device.

A device for determining the pain sensitivity of the skin in the diagnosis of vibrational disease contains a cylindrical body 1, on the proximal end 2 of which an acting needle 3 is installed. A screw thread 4 is made on the distal section of the housing 1, on which a nut-regulator 5 for exiting the acting needle 3 from the dimensions of the housing 1 is installed and pointer arrow 6 is made. On the distal section of the housing 1, a scale 7 is provided for the output of the acting needle 3 on the patient’s body, interacting with the pointer arrow 6 located on the nut ke-regulator 5. The diameter of the device can be 20-30 mm, the length of the case is 100-150 mm, and the weight is 250 grams.

A device for diagnosing vibrational disease is used as follows. By rotating the adjusting nut 5 on the screw thread 4, the end of the acting needle 3 is positioned at the level of the end of the adjusting nut 5. The device is freely positioned on the back surface of the patient’s hand and, by gradually slowly screwing the adjusting nut 5, push the end of the needle 3 out of the body until until the patient feels pain. The depth of immersion of the needle 3 in the patient’s skin (threshold of pain sensitivity) is determined on a scale of 7 using the arrow 6.

The housing 1 and the adjusting nut 5 can be made of stainless metal alloy or aluminum alloy.

Before use, the device is subjected to aseptic processing.

The strictly defined weight of the device (250 grams) allows comparability of the results of the definitions of various patients.

Using the proposed device allows with minimal effort to determine pain sensitivity in the diagnosis of vibration disease with great accuracy.
