Abstract

The invention discloses a medical fixing sticker, a preparation method and a use method thereof, comprising a protective film (1), a modified pressure-sensitive adhesive layer (2), a non-woven fabric layer (3), a pressure-sensitive adhesive layer (4), The PET film (5), the pressure-sensitive adhesive layer (6), and the protective film (7) are stacked in sequence, and the lower surface of the non-woven fabric layer (3) and the upper surface of the PET film (5) pass through the pressure-sensitive adhesive layer (4 ) bonding, the modified pressure-sensitive adhesive layer (2) is coated on the upper surface of the non-woven fabric layer (3), the pressure-sensitive adhesive layer (6) is coated on the lower surface of the PET film (5), and the protective film (1 ) is pasted on the side of the modified pressure-sensitive adhesive layer (2) opposite to the non-woven fabric layer, and the protective film (7) is pasted on the side of the pressure-sensitive adhesive layer (6) opposite to the PET film (5). The medical fixing patch of the present invention uses modified pressure-sensitive adhesive as the skin-sticking pressure-sensitive adhesive. In addition to providing enough stickiness, it can also ensure no irritation and no sensitization to the skin, and it is easy to tear off after use, reducing the problem of degumming.

Description

technical field [0001] The invention relates to the technical field of fixation patches, in particular to a medical fixation patch, a preparation method and a use method thereof. Background technique [0002] Medical fixation stickers are directly attached to the skin and are used for fixing various dressings and binding and fixing medical devices (such as intravenous needles, medical drainage tubes, indwelling needles, etc.). At present, the fixed stickers on the market are too sticky to the skin. When they are replaced, they are easy to scratch the skin and have residual glue; and they are irritating to the skin after long-term use, causing itching, redness and other adverse reactions. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a medical fixing patch, a preparation method and a use method thereof, which are non-irritating and non-sensitizing to the skin. [0004] In order to achieve the above object, th...
