Method for manufacturing medical vacuum bag

Abstract

The invention discloses a method for manufacturing a medical vacuum bag, which comprises the following steps: 1) providing TPU or nylon fabrics with the thickness of between 0.4 and 0.5 millimeter; 2)preparing a 3 to 9 percent PVA solution; 3) using the PVA solution prepared in the second step to coat the TPU or nylon fabrics provided in the first step, wherein the coating thickness is between 0.10 and 0.18 millimeter; 4) drying the TPU or nylon fabrics obtained in the third step, wherein the drying temperature is between 60 and 90 DEG C; and 5) adopting a high-frequency welding method to weld side lines of the TPU or nylon fabrics obtained in the fourth step, welding three sides, filling foamed particles into the obtained product, placing a filter sheet into the obtained product, adopting the high-frequency welding method to weld the final side of the fabrics, adopting the high-frequency welding method to weld a gas nipple on the fabrics, and inserting a quick coupling on the gas nipple. The invention has the advantages of simple process, low cost, good airtightness and quality reaching the standard.

Description

technical field [0001] The invention relates to a manufacturing method of a medical device, in particular to a manufacturing method of a medical vacuum bag. Background technique [0002] Medical vacuum fixing bag, also called medical vacuum bag, is a product that uses vacuum to shape and fix the human body. Because the vacuum fixing bag has the advantages of light weight, good shape, strong radiation transmission, and reusability, it can be widely used in position setting and position fixation during cancer radiotherapy, and can also be used in operations that require special Position fixation and position fixation in pre-hospital first aid. In order to ensure the airtightness of medical vacuum bags, foreign countries usually use multi-layer composite fabrics to manufacture vacuum fixed bags. For example, 5-layer co-extrusion or 7-layer co-extrusion fabrics are used to manufacture multi-layer co-extrusion fabrics. The price of multi-layer co-extrusion fabrics is expensive, ...

In order to ensure the airtightness of medical vacuum bags, foreign countries usually use multi-layer composite fabrics to manufacture vacuum fixed bags. For example, 5-layer co-extrusion or 7-layer co-extrusion fabrics are used to manufacture multi-layer co-extrusion fabrics. The price of multi-layer co-extrusion fabrics is expensive, which leads to product costs stay high
