Problems solved by technology

In these studies, for specific types of pressure clothing, the size generally changes in 3 or 4 levels, and the range of motion is limited. The accuracy of the pressure comfort and discomfort mapping range obtained is low, and is limited to specific clothing styles.
For the difference threshold, it is often used for sensory perception such as hearing and touch, but has not been applied to the characterization of clothing pressure perception ability

Embodiment 1

[0028] Example 1: Testing and Calculation of the Pressure Comfort Threshold of the Abdominal Convexity

[0029] Step 1. The subject first enters the laboratory, and puts a marking point on the designated position of the human body (to facilitate the consistency of subsequent measurement positions and avoid errors). When marking, the subject stands naturally with his arms drooping.

[0030] Step 2. Wear elastic bandages to the subjects, gradually reduce the size of the bandages, and gradually increase the pressure, so that the subjects can remember different degrees of pressure and corresponding comfort, until the subjects can't bear it (unable to Continue to wear during the day), and then gradually reduce the pressure, so that the subjects reconfirm the different degrees of pressure and comfort.

[0031] Step 3. Fix the pressure sensor on the marked point of the test site, wear the sample to the subject (keep the test point passing the horizontal centerline of the sample), and...

Embodiment 2

[0040] Example 2: Test and Calculation of Differential Pressure Threshold at the Rear Center of the Subject's Thigh

[0041] Take the pressure value of the control clothing near the comfort threshold range. For example, if the pressure comfort threshold of the test subject at the rear center of the thigh is 2640Pa, then take three pressure values ​​of the control clothing, as shown in Table 2, which are 1000Pa, 2000Pa and 3000Pa respectively. . First, adjust downwards from 2000Pa, and reduce it by about 100-200Pa each time, and let the experimenter feedback that the pressure is greater, smaller, or equal to 1000Pa. When the experimenter feedbacks that the pressure is smaller than 1000Pa, a set of actions is completed; then, from 500Pa to Up-regulation, increasing by about 100-200Pa each time, let the experimenter feedback that the pressure is greater, smaller, or equal to 1000Pa. When the experimenter feedbacks that the pressure is greater than 1000Pa, a set of actions is comp...

Abstract

The present invention relates to a pressure clothes pressure comfort threshold test method. The method comprises the following steps: designing and making a double-buckle elastic bandage, selecting a pressure comfort threshold test point on a body; and testing the pressure comfort threshold and the differential pressure threshold of each test point based on the psychophysics step-limit method. Compared to the prior art, the pressure clothes pressure comfort threshold test method employs the psychophysics step-limit method to perform test and calculation of the pressure comfort threshold, and is more accurate in test result compared to the traditional psychological scale evaluation method based on the limited scale change sample dress wearing experiment so as to effectively avoid the influences of the clothes styles and the structure on the pressure comfort range. The pressure clothes pressure comfort threshold test method performs test and calculation of the differential pressure threshold based on the psychophysics step-limit method and can represent the perception distinguishing ability of each portion for the minimum pressure stimulation.

Description

technical field [0001] The invention relates to a method for testing and calculating the pressure comfort threshold and differential pressure threshold of pressure clothing, which is suitable for testing and calculating the pressure comfort threshold and differential pressure threshold of various pressure clothing, and the pressure clothing includes tights , shapewear, compression stockings, compression bandages, etc. Background technique [0002] Pressure clothing, that is, clothing that can generate pressure on specific parts of the human body, including shapewear that can enhance breasts, reduce abdomen, lift hips and legs; medical socks and bandages that can improve blood circulation in the lower limbs, relieve and treat venous diseases; Tight sportswear such as cycling suits that can promote microcirculation in the body and enhance motor function. The size and distribution of clothing pressure is the key to realize the above functions, and it is also the main aspect th...
