Abstract

The invention belongs to a medical auxiliary device, which adopts a pressure detection device to realize convenient and accurate detection of human pain pressure. The technical solution of the present invention is to combine a micrometer, a spring, and a contact cap into a set of measuring devices. When the cap is in contact with human skin and the spring is in a natural state, twist the knob of the micrometer so that the spring is in a compressed state. The cap transmits force to the human body and stimulates the human body. When the pain threshold of the body is reached, the person feels pain and reads the micrometer indication, that is, the spring deformation, which is converted into pressure, which can accurately measure the pain pressure of the human body.

Description

A high-precision detection device for human pain and pressure

technical field

The invention belongs to a medical auxiliary device, which adopts a pressure detection device to realize convenient and accurate detection of human pain pressure.

Background technique

The examination of human tenderness points is an important link in the process of modern medical clinical diagnosis and disease prevention, especially the detection of pain points on a specific part and acupoint is of great significance to the early diagnosis and prevention of diseases. However, in the current medical testing process, small wooden sticks, pin needles, etc. are often used for testing. These testing methods are difficult to achieve accurate detection of pain pressure. Aiming at the above problems, the inventor of the utility model conducted in-depth research on this, and invented a set of convenient and accurate detection device.

Contents of the invention

The purpose of the present invention is to propose a detection device with strong operability and accurate detection in view of the difficulty in detecting pain pressure in modern medicine.

The technical solution of the present invention is to form a set of measuring device with a micrometer, a spring and a contact cap. When the cap is in contact with human skin and the spring is in a natural state, twist the knob of the micrometer so that the spring is in a compressed state. The cap transmits the force to the human body and stimulates the human body. When the pain threshold of the body is reached, the person feels pain and reads the micrometer indication, that is, the spring deformation, which is converted into pressure, which can accurately measure the pain pressure of the human body.

Uses and advantages of this method

The invention uses a micrometer to accurately measure the deformation of the spring, has low cost, strong operability, accurate pressure test, repeatable and practical, can well solve the difficulty of human pain pressure measurement, has good promotion and practical value, and wide application will produce Good economic and social benefits have a positive impact on the development of medical care.

Description of drawings

Accompanying drawing is the structural diagram of the invention, wherein: 1 micrometer micrometer screw rod, 2 springs, 3 contact caps.

Detailed ways

Examples are given below to further describe the present invention.

The human pain pressure measuring device is composed of a micrometer screw 1, a spring 2 and a contact cap 3.

The micrometer adopts digital display, and the measurement accuracy is 0.001mm, which is used to accurately measure the spring deformation. The spring 2 is a cylindrical spring with a known elastic coefficient k, and is used for exerting pain-sensing force on the human body. The production method of contact cap 3 can adopt 3D printing technology, which is divided into upper and lower parts. The inner cavity of the lower part of the carrier is filled with the spring 2 to realize the clamping of the spring 2.

The outer diameter of the spring 2 is slightly smaller than the inner diameter of the contact cap 3, so that the spring 2 is packed into the inner cavity of the contact cap 3.

Put the contact cap 3 on the micrometer screw 1, the outer diameter of the spring 2 is slightly smaller than the outer diameter of the micrometer screw, the spring 2 is in contact with the end of the micrometer screw 1, and the inner diameter of the contact cap 3 is slightly larger than the micrometer screw 1 OD for socketing.

How to use: Select the earlobe of the human body for the measurement site. After the device is assembled according to the assembly relationship, the section of the measuring anvil is measured, and the tip of the contact cap 3 is respectively in contact with the earlobe without extrusion or deformation. The point of force is aligned with the measurement acupuncture point to ensure that the spring 2 is in a state of natural elongation without pressure on the skin, and record the reading x ₁ of the micrometer at this time. Then, slowly turn the micrometer knob to make the micrometer screw 1 push the compression spring 2 to apply pressure to the earlobe. When the person under test feels pain, immediately stop turning the knob, and record the reading x ₂ of the micrometer at this time.

x ₁ -x ₂ =x (spring compression), according to Hooke's law F=kx, the pain pressure value of the tested person can be obtained. This pressure value can be used as a reference pressure value for the human body to perceive pain.
