Problems solved by technology

[0008] At present, most of the electrostatic products and magnetic therapy products used in clinical treatment use a single electrostatic or magnetic therapy method, which has problems such as poor therapeutic effect and small application range. Some progress has been made in this area, but the method of combining electrostatic and magnetic therapy is still in the exploratory stage, and there is no finalized medical product for clinical use.

example 1

[0038] In the first step, the medical grade polylactic acid with a molecular weight of 10W is added to ethyl acetate to dissolve to obtain a mixed solution. In order to ensure that the mixed solution completely dissolves the medical grade polylactic acid without residue, stir at room temperature with a magnetic stirrer at a speed of 100r / min 5 minutes until completely dissolved, then the mixed solution was mixed by ultrasonic vibration, exhausted for 30 minutes, and then the exhausted mixed solution was molded, turned, calendered, and cut to form a polylactic acid film with a film thickness of 0.3mm. Among them, the molded The temperature is 250°C;

[0039] In the second step, spread the polylactic acid film cut into 100mm*100mm on a flat panel, and after cleaning the film with alcohol, put PVDC (vinylidene chloride-acrylate copolymer) with good barrier properties on the polylactic acid film Coating on one side, and then drying in an oven for 48 hours to form a composite film;...

[0046] In the first step, the medical grade polylactic acid with a molecular weight of 20W is added to ethyl acetate to dissolve to obtain a mixed solution. In order to ensure that the mixed solution completely dissolves the medical grade polylactic acid without residue, stir with a magnetic stirrer at a speed of 100r / min at room temperature 5 minutes until completely dissolved, then the mixed solution was mixed by ultrasonic vibration, exhausted for 30 minutes, and then the exhausted mixed solution was molded, turned, calendered, and cut to form a polylactic acid film with a film thickness of 0.5mm. Among them, the molded The temperature is 280°C;

[0047] In the second step, spread the polylactic acid film cut into 100mm*100mm on a flat panel, clean the film with alcohol, and then coat one side of the polylactic acid film with PTFE (polytetrafluoroethylene) with good barrier properties. Cover, and then dry in an oven for 48 hours to make a composite film;

[0054] In the first step, add medical grade polylactic acid with a molecular weight of 30W to ethyl acetate to dissolve to obtain a mixed solution. In order to ensure that the mixed solution completely dissolves the medical grade polylactic acid without residue, stir with a magnetic stirrer at a speed of 100r / min at room temperature 5min until completely dissolved, then the mixed solution was mixed by ultrasonic vibration, exhausted for 30min, and then the exhausted mixed solution was molded, turned, calendered, and cut to form a polylactic acid film with a film thickness of 0.7mm. Among them, the molded The temperature is 300°C;

[0055] In the second step, spread the polylactic acid film cut into 100mm*100mm on a flat panel, and after cleaning the film with alcohol, place PVDF (polydenetetrafluoroethylene) with good barrier properties on one side of the polylactic acid film.

Abstract

The invention discloses an ion sensing film and a preparation method thereof. The ion sensing film comprises a back lining layer, a permanent magnet layer, an adhesive layer and a compound film layer, the permanent magnet layer is round sheet-shaped and arranged on the back lining layer, a metal foil is arranged at each of two sides of the compound film layer, one surface of the compound film layer covered by the metal foils is arranged on the back lining layer and permanent magnet layer, and release paper covers the other surface to obtain the ion sensing film. The ion sensing film uses degradable renewable material, and therefore, the ion sensing film is friendly to the environment, and moreover, the biocompatibility is good, the common irritability, infection and the like caused by traditional dressing can be effectively overcame, and more important, the ion sensing film comprehensively uses the principle that a static electric field and a magnetic field have a biological stimulation effect to the human body, and the ion sensing film has obvious treatment and rehabilitation effects for the ache caused by cervical vertebra, degenerated lumbar, hyperostosis, soft tissue injury and the like.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an ion-sensing membrane and a preparation method thereof. Background technique [0002] Charged functional materials are a class of dielectric materials that can store space charges and dipole charges for a long time. Using the external field effect and microcurrent effect of charged materials can effectively regulate the internal circulation and metabolic process of organisms, play a role in the electrolysis regulation of tissue cells in organisms, the conduction of nerve signals, and the induction and repair of injured tissues, so as to achieve therapeutic effect. disease purpose. [0003] Charged materials have become a research hotspot in the field of medicine due to their excellent electrostatic therapeutic ability, and will quickly become materials with clinical and commercial value. According to relevant research, such materials can be used in the treatment of fracture reh...
