Embodiment 1

[0023] Example 1: Put the activated carbon fiber into the sample bag and seal it with 60 Co-γ rays are pre-irradiated, and the irradiation dose is 48kGy to obtain pre-irradiated activated carbon fibers. Pre-irradiated activated carbon fibers were mixed with 25% acrylic acid monomer solution in water system, 4×10 -4 mol / L mohr salt, reacted at 70°C for 3h under a nitrogen atmosphere, washed with water, and dried at 50°C to prepare activated carbon fiber cloth and activated carbon fiber felt. Calcium alginate fiber is used as raw material, the alginate fiber membrane is prepared by needle punching process, the multi-layer composite process is adopted, the activated carbon fiber cloth 2 is used as the inner layer, the activated carbon fiber felt 4 is used as the adsorption enhancement layer, and the alginate fiber membrane 3 is used as the binding layer The activated carbon fiber composite dressing is made, and the outer layer is made of a non-woven fabric 5 coated with medica...

[0024] Example 2: Put the activated carbon fiber into the sample bag and seal it with 60 Co-γ rays are pre-irradiated, and the irradiation dose is 48kGy to obtain pre-irradiated activated carbon fibers. The pre-irradiated activated carbon fiber was mixed with methanol system and 15% acrylic acid monomer solution, 2×10 -4 mol / L Mohr salt, reacted at 50°C for 5h under nitrogen atmosphere, washed with water, and dried at 60°C to prepare activated carbon fiber cloth and activated carbon fiber felt. Calcium alginate fiber is used as raw material, the alginate fiber membrane is prepared by needle punching process, the multi-layer composite process is adopted, the activated carbon fiber cloth 2 is used as the inner layer, the activated carbon fiber felt 4 is used as the adsorption enhancement layer, and the alginate fiber membrane 3 is used as the binding layer The activated carbon fiber composite dressing is made, and the outer layer is made of a non-woven fabric 5 coated with me...

Embodiment 3

[0025] Example 3: Put the activated carbon fiber into the sample bag and seal it with 60 Co-γ rays are pre-irradiated, and the irradiation dose is 48kGy to obtain pre-irradiated activated carbon fibers. Pre-irradiated activated carbon fibers were mixed with 35% acrylate monomer solution in water system, 8×10 -4 mol / L mohr salt, reacted at 90°C for 2h under a nitrogen atmosphere, washed with water, and dried at 45°C to prepare activated carbon fiber cloth and activated carbon fiber felt. Calcium alginate fiber is used as raw material, the alginate fiber membrane is prepared by needle punching process, the multi-layer composite process is adopted, the activated carbon fiber cloth 2 is used as the inner layer, the activated carbon fiber felt 4 is used as the adsorption enhancement layer, and the alginate fiber membrane 3 is used as the binding layer The activated carbon fiber composite dressing is made, and the outer layer is made of a non-woven fabric 5 coated with medical st...

Abstract

The invention relates to a medical active carbon fiber dressing and a preparation method thereof. The medical dressing mainly consists of two layers of active carbon fiber materials and one layer of alginate fiber membrane, wherein an inner layer is formed by an active carbon fiber cloth, a middle layer and a compound layer are formed by an active carbon fiber mat and an alginate fiber membrane, and an outer layer is a fabric coated with a medical adhesive bonding layer which is formed by a breathable gauze or a non-woven fabric, so that the dressing can be conveniently fixed on the surface of a wound. The medical dressing has better adsorptive property and antibacterial property and capabilities of effectively absorbing effusions such as plasma, pimples and the like effused from the surface of the wound without bonding the wound, providing a wet environment needed for quick wound healing, promoting the growth of repair cells and reducing the dressing replacing time. The method provided by the invention is convenient, practical and efficient.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to an activated carbon fiber medical dressing and a preparation method thereof. Background technique [0002] Medical dressings are a type of clinical medical material that temporarily covers burns, ulcers, wounds and other wounds. Its main function is to control the exudate of the wound and protect the wound from external pollution such as bacteria and dust particles. Existing medicines for treating burns and scalds do not work well. This is because the carriers in these pharmaceutical products cannot well load the active pharmaceutical ingredients for treating burns and scalds, requiring frequent replacement of pharmaceutical products, which affects the healing of the wound. Therefore, there is a great need for improved drug carriers for treating burns and scalds and drug products prepared therefrom. [0003] The main component of the new alginate dressing is taken from alg...
