Abstract

<P>PROBLEM TO BE SOLVED: To provide a device for quantitatively measuring examinee's sensitivity to pressure to the body surface by adding pushing force to an inner cylinder so as to compress a compression coil spring onto the body surface, and multiplying compressed distance by a spring constant. <P>SOLUTION: For examining the sensitivity to pressure, pushing force is added to the inner cylinder 1 so as to compressing the compression coil spring 3. The compressed distance is measured by the millimeter gauge 4 on an outer cylinder 2, and it is multiplied by the spring constant, so that the examinee's sensitivity to pressure on the body surface is quantitatively measured. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

In order to examine the pressure sensation on the human body surface, the present invention compresses the compression coil spring by applying a pressing force to the inner cylinder on the human body surface, and multiplies the compressed distance by the spring constant to sense the pressure sensation on the body surface. Is devised so that it can be measured quantitatively.
The present invention relates to a simple pressure sensation inspection device designed to measure a compressed distance on a ruler in units of mm of an outer cylinder and to measure a pressed force by multiplying by a spring constant.

Conventionally, there was no pressure sensor for the surface of a human body.
In general hospitals and the like, there were tactile sensation instruments, pain sensation examination instruments, temperature sensation examination instruments, and the like, but there was no specific examination instrument related to pressure sensation.
When testing pressure sensation, a thick book or the like was placed on a test part of the human body and asked whether or not pressure was felt.

Problems to be solved by the invention

When examining the pressure sensation on the human body surface, a thick book or the like was placed on the person's examination site and asked whether or not pressure was felt, and quantitative examination was not performed. .
In addition, because pressure sensation is considered to be a superficial sensory receptor similar to tactile sensation, it was performed as a substitute for pressure sensation testing by examining tactile sensation.
However, there are concerns about “rubbing” in patients and elderly people who have been bedridden on the bed for a long period of time. Even difficult.
In order to prevent and prevent floor rubbing, a quantitative pressure sensation test on the back, buttocks, and buttocks of the floor rubbing site on the body surface is indispensable.
The present invention has been made to solve these problems.

Means for solving the problem

A compression coil spring (3) was installed at the bottom of the outer cylinder (2) with a large inner diameter on which a ruler (4) in mm was displayed, and the inner cylinder (1) with a smaller inner diameter was inserted into the outer cylinder (2). Device.
In the pressure sensation test, the compression coil spring (3) is compressed by applying a force to the inner cylinder (1) on the human body surface. The compressed distance was measured on the ruler (4) in mm of the outer cylinder (2), and the pressure on the human body surface was measured by multiplying by the spring constant.
A simple pressure sensation tester configured as described above.

The invention's effect

It is inexpensive and portable, and can accommodate different limb positions and postures.
A bedridden patient can be examined on the bed in the supine or lateral position.
Moreover, the range of pressure sensation strength can be expanded by replacing the compression coil spring.
It can be manufactured with inexpensive materials and can be installed in general hospitals and homes, and anyone can easily perform pressure-sensitive tests.

  When this inspection apparatus is used, an appropriate inspection can be performed by applying a material that matches the human skin to the portion of the inner cylinder end that contacts the human skin.

  It is a perspective view of the present invention.   It is a side view of the present invention.

Claims (1)

  A compression coil spring (3) was installed at the bottom of the outer cylinder (2) with a large inner diameter on which a ruler (4) in mm was displayed, and the inner cylinder (1) with a smaller inner diameter was inserted into the outer cylinder (2). With the device, for pressure sensory test, a person presses the inner cylinder (1) on the body surface to compress the compression coil spring (3), and the compressed distance is set to a ruler (4 mm) of the outer cylinder (2). ) A simple pressure sensation inspection device characterized in that the force measured by the above and multiplied by the spring constant can be measured by a person pressing the body surface.
