Example Embodiment

[0028] Example 1: Test and calculation of pressure comfort threshold of abdominal convex point

[0029] Step 1. Participants first enter the laboratory and place markers on designated positions on the human body (to facilitate the consistency of subsequent measurement positions and avoid errors). When marking, the subjects stand naturally with their arms drooping.

[0030] Step 2. Put the subject on an elastic bandage, gradually reduce the size of the bandage, so that the pressure gradually increases, so that the subject can remember the different degrees of pressure and the corresponding comfort, until the subject cannot bear 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, and put the sample on the test subject (keep the test point passing through the horizontal centerline of the sample), and adjust the...

Example Embodiment

[0040] Example 2: Test and calculation of the differential pressure threshold of the posterior center point of the mid-thigh of the subject

[0041] Take the control clothing pressure value near the comfort threshold range. If the pressure comfort threshold of the subject at the center of the back of the thigh is 2640Pa, then take three control clothing pressure values, as shown in Table 2, respectively 1000Pa, 2000Pa and 3000Pa . First, adjust downward from 2000Pa, and reduce by about 100-200Pa each time. Let the experimenter report that the pressure is greater, smaller, or equal to 1000Pa. When the experimenter's feedback is less than 1000Pa, a set of actions is completed; then, from 500Pa to Adjust up, increase by about 100-200Pa each time, let the experimenter feedback that the pressure is larger, smaller, or equal to 1000Pa. When the experimenter's feedback is larger than 1000Pa, a set of actions is completed. Repeat the above two sets of actions again. The average value o...

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...
