Abstract

The invention discloses dry-adhesive medical adhesive tape and a preparing method of the dry-adhesive medical adhesive tape. The medical adhesive tape is a thin polymer film provided with micron order mushroom-shaped poles of an arrayed structure and polymer is dimethyl silicone polymer. The invention further relates to the preparing method of the dry-adhesive medical adhesive tape. The method comprises the steps that step 1, a first silicon wafer is taken and spin-coated with photoresist, drying is conducted, exposure and development are conducted through UV light, and therefore an arrayed hole structure template can be obtained; step 2, the dimethyl silicone polymer is cast on the arrayed hole structure template, solidification is conducted, and the dimethyl silicone polymer is taken down; step 3, a second silicon wafer is taken and spin-coated with dimethyl silicone polymer, the dimethyl silicone polymer taken down in the step 2 is placed on the second silicon wafer, after being taken down from the second silicon wafer, the dimethyl silicone polymer is placed on a third silicon wafer, solidification is conducted, and the dimethyl silicone polymer is taken down, so that the dry-splicing adhesive tape is obtained. The dry-adhesive medical adhesive tape adheres to the skin through VDW (Van der Waals force), a physiological electrode for measurement can be fixed, irritation to the skin is avoided, the adhesive strength of the dry-adhesive medical adhesive tape cannot be reduced after the dry-adhesive medical adhesive tape is used for a long time, and the dry-adhesive medical adhesive tape is suitable for long-time physiological signal detection.

Description

technical field [0001] The invention belongs to the medical field, and in particular relates to a dry bonding medical adhesive tape and a preparation method thereof. Background technique [0002] In recent years, with the continuous development and maturity of micro-electro-mechanical systems (MEMS: Micro-Electro-Mechanical Systems) technology, the application range of micro-systems such as micro-electronic devices and micro-sensors has continued to expand, and has been widely used in civil, medical, military, etc. field. The bionic technology based on micromachining technology has been developed rapidly. [0003] In a real-time medical care system, diagnostic devices are fixed on the skin by a medical tape to monitor important signals of the human body, especially heart diseases often require long-term monitoring. Therefore, this requires the use of non-irritating, biocompatible, and long-term adhesive medical tapes for monitoring. Since the skin of the elderly or infant...
