Embodiment 1

[0042] Embodiment 1 of the present invention also discloses a method for making a medical adhesive tape substrate, comprising the following steps:

[0043] 1) Extract the pulp from wormwood straw, Artemisia annua straw and cotton respectively, mix the various pulps, and use an ultrasonic device to urge the mixed pulp to vibrate so that the various pulps are mixed evenly. Plant fibers are extracted from the meal, wherein the mass ratio of the wormwood straw, Artemisia annua straw, and cotton is 1.5:1.5:3.5;

[0044] 2) According to the mass percentage calculation, 55% of the plant fiber, 25% of the PE fiber and 1% of the seaweed fiber are mixed, and a wet strength agent is added into the mixed fiber, and then the mixed fiber is passed through a circular net or an inclined A web paper machine is formed into a tape substrate, wherein the addition of the wet strength agent is 0.2% of the mass of all fibers;

[0045] 3) Soak the adhesive tape base material in traditional Chinese m...

Embodiment 2

[0052] Implementation 2 of the present invention also discloses a method for making a medical adhesive tape substrate, comprising the following steps:

[0053] 1) Extract the pulp from wormwood straw, Artemisia annua straw and cotton respectively, mix the various pulps, and use an ultrasonic device to urge the mixed pulp to vibrate so that the various pulps are mixed evenly. Plant fibers are extracted from the meal, wherein the mass ratio of the wormwood straw, Artemisia annua straw, and cotton is 2:2:3.5;

[0054] 2) According to the mass percentage calculation, 60% of the plant fiber, 25% of the PE fiber and 2% of the seaweed fiber are mixed, and a wet strength agent is added to the mixed fiber, and then the mixed fiber is passed through a circular net or an inclined A web paper machine is formed into a tape substrate, wherein the addition of the wet strength agent is 0.3% of the mass of all fibers;

[0055] 3) Soak the adhesive tape base material in traditional Chinese med...

Embodiment 3

[0062] Implementation 3 of the present invention also discloses a method for making a medical adhesive tape substrate, comprising the following steps:

[0063] 1) Extract the pulp from wormwood straw, Artemisia annua straw and cotton respectively, mix the various pulps, and use an ultrasonic device to urge the mixed pulp to vibrate so that the various pulps are mixed evenly. Plant fibers are extracted from the meal, wherein the mass ratio of the wormwood straw, Artemisia annua straw, and cotton is 2.5:2.5:4.5;

[0064] 2) According to the mass percentage calculation, 60% of the plant fiber, 25% of the PE fiber and 2% of the seaweed fiber are mixed, and a wet strength agent is added to the mixed fiber, and then the mixed fiber is passed through a circular net or an inclined A web paper machine is formed into a tape substrate, wherein the addition of the wet strength agent is 0.5% of the mass of all fibers;

Abstract

The invention provides a medical adhesive tape base material and a preparation method thereof. The medical adhesive tape base material comprises the following components in percentage by weight: 45-80percent of plant fibers, 15-40 parts of PE fibers and 1-5 percent of alginate fibers, wherein the plant fibers comprise plant mixed fibers extracted from pulp mixed by artemisia vulgaris straws, artemisia annua straws and cotton, and the mass ratio of the artemisia vulgaris straws to the artemisia annua straws to the cotton is (1-3):(1-3):(3-5). The plant fibers ( comprising the artemisia vulgaris straws, the artemisia annua straws and the cotton) adopted by the medical adhesive tape base material not only is green and environmentally-friendly, but also ensures that a medical adhesive tape issoft, loose and thick; with the adoption of the plant fibers, the medical adhesive tape can have natural fragrance and soothe nervousness, dissatisfaction and other negative emotions of a patient; with the adoption of the plant fibers, the effects of calming, soothing and bacteria-inhibiting skin swollen by needling can be realized.

Description

technical field [0001] The invention relates to the field of medical product base materials, in particular to a medical adhesive tape base material and a manufacturing method thereof. Background technique [0002] In a real-time medical care system, the diagnostic device is fixed on the skin with a medical tape to detect important signals of the human body, especially the detection of the heart often requires long-term detection, and in some operations or the treatment of some diseases. For infusion, the infusion tube needs to be fixed on the human body with medical tape. All of the above require medical tapes with good air permeability, non-irritation, biocompatibility, and long-term adhesion. Especially for some allergic people or babies with delicate skin, medical tapes with the above-mentioned excellent properties are needed. At present, common medical tapes are perforated to obtain good air permeability, and special sawtooth processing is performed on the edge of the s...
