Description

DESCRIPTION

Pressure pain threshold measurement device for nerve trunks.

Technique sector

An algometer is considered a device for the measurement of the pressure pain threshold in humans, being included as a valid and reliable device for its measurement in the health sciences sector. Due to the circular contact surface of the 1 cm 'algometers, they do not allow the evaluation of the pain threshold under pressure exactly on the path of the accessible nerve trunks. Nerve trunks are divisions of the peripheral nervous system, which can produce sensitization with sensory, motor, and autonomic symptoms. Therefore, the evaluation of the pressure pain threshold of superficial nerve trunks in accessible regions is of great interest in current clinical studies, making it necessary to have a device that specifically evaluates the accessible superficial areas of nerve trunks.

Background of the Invention

There are valid and reliable algometers that measure the pressure pain threshold in kg / cm2 with a flat circular applicator with a diameter of 1.52 cm2. However, the present invention allows the applicator to be adapted to the surface of the accessible peripheral nerve trunks, which will improve the reliability of the algometer for its measurement.

The device presented allows to quantify in kilograms per square centimeter the pain threshold to the pressure on the accessible surface of the peripheral nerve trunks.

Explanation of the invention

The present invention relates to an adapter device for measuring pressure pain threshold for peripheral nerve trunks. The device has a trapezoidal piece with a square base of 0.25 cm ² area to adapt to an algometer to measure the pressure pain threshold in the accessible area of the superficial peripheral nerve trunks, allowing quantification of the differences in different body regions and nerve pathways.

The device for the pressure pain threshold that we present has the advantage of accurately measuring the palpation area in kilograms per square centimeter that we want to detail on the peripheral nerve trunks.

To complement the description that will be made below and in order to help a better understanding of the characteristics of the invention, the present descriptive memory is accompanied by a set of plans based on whose figures innovations and advantages of the device object of the invention.

Thanks to the use of this applicator, the reliable evaluation of the pain pressure threshold coinciding with the accessible surface area of the peripheral nerve trunks will be allowed.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the figures outlined, it can be seen how the algometer in figure 1 has a lower screw (1) that fits into the upper thread (2) of the metal part of the invention or applicator in figure 2.

Figure 2 shows the trapezoidal metal part of the invention, with a thread (2) on the upper face to fit the algometer (1) and a lower square surface (3) to measure the pain threshold at the pressure of 0.25 cm2 (0.5 cm each side).

Claims (2)

1. Pressure pain threshold measurement device for peripheral nerve trunks, characterized by a trapezoidal metal part with a flat and square 0.25 cm2 lower surface (3) coincident with the accessible area of the peripheral nerve trunks that can be attached to the algometer and fixed with a screw. 2. Pressure pain threshold measurement device for peripheral nerve trunks, according to claim 1, characterized by an upper thread (2) that allows coupling and connects to the lower screw of the algometer (1), unifying both parts for the measurement.
