Problems solved by technology

However, the conversion factor of the conversion factor method does not consider the performance of the fabric, so the dimensional accuracy of the pressure garment made by this method is low, which affects the inhibitory effect on hypertrophic scars
Another major method of making pressure garments is based on the Laplace equation, which takes into account the tensile properties of the fabric and the size of the human body, so the accuracy of the obtained pressure garments is improved compared with the conversion coefficient method; but based on the Laplace equation The production method of pressure garments based on the Lars equation differs in the way of using the tensile properties of the fabric and the method of obtaining the body size due to the different scope of application

Embodiment 1

[0020] Fabric information: The raw material is nylon / spandex (70 / 30), the fabric is flat, and the weight is 263g / m 2 , the longitudinal density is 30 circles / cm, and the transverse density is 26 circles / cm.

[0021] The fixed elongation ratios adopted for fabric stretching are respectively: 10%, 20%, 30%, 40%, 50% and 60%. The relationship between fabric unit stress (cN / cm) and elongation (%) is: unit stress=228.184×(elongation^0.815). Starting from the radial neck of the subject's wrist, take a test circle every 5cm along the length of the arm and measure the corresponding circumference (15cm, 16cm, 20cm, 23cm, 23cm, 23.4cm, 22.7cm, 23cm); the width of the sample for testing the constant elongation of the fabric is 5cm; the garment is pressed at 32hPa (about 24mmHg). The product of the patient's body size (circumference size), fabric width (sample width) and the garment pressure to be applied is used as the dividend, and twice π is used as the divisor to obtain the fabric u...

Abstract

The invention relates to a manufacturing method of a tubular pressure garment. The manufacturing method comprises the following steps: (1) testing tensile properties of a fabric at different elongation rates, and fitting a relation formula of a fabric unit stress and the elongation rate; (2) obtaining a fabric unit stress under certain garment pressure by taking a product of the body size of a patient, the width of the fabric and the garment pressure to be applied as a dividend as well as double pi as a divisor; (3) substituting the fabric unit stress obtained in the step (2) into the relation formula of the step (1), so as to obtain the fabric elongation rate; (4) obtaining a conversion ratio according to the relation between the fabric elongation rate and the conversion ratio; (5) obtaining the size of the pressure garment according to the conversion ratio and the body size of the patient, and drawing graph paper according to the size; and (6) cutting the fabric according to the graph paper, and sewing the pressure garment. According to the tubular pressure garment manufactured by virtue of the manufacturing method, the garment pressure applied to a wound is in a required range. The manufacturing method is mainly used for manufacturing a tubular pressure garment for recovery of hypertrophic scars.

Description

technical field [0001] The invention relates to a method of manufacturing a tubular compression garment. Background technique [0002] Pressure therapy is one of the most effective methods to prevent and treat moderate to severe hypertrophic scars. This therapy is simple to operate, has definite curative effect, is inexpensive, and is a non-invasive treatment method. The main principle of pressure therapy in the treatment of hypertrophic scars is to restrict blood flow into the scar area by means of specific pressure (clothing pressure) exerted by pressure garments (also known as elastic garments, elastic sleeves) and prevent the growth of hypertrophic scar tissue, thereby limiting or improving scar tissue. Hypertrophic scar formation. Therefore, the garment pressure exerted by the compression garment on the hypertrophic scar is the key to determine the curative effect, and the precise design of the garment that can apply the garment pressure is crucial for the treatment of...
