Abstract

The invention belongs to the technical field of medical devices, in particular to a superabsorbent medical absorbent cotton gauze and a preparation method thereof. The highly water-absorbing medical absorbent cotton gauze of the present invention is formed by blending seaweed fibers and cotton fibers. The seaweed fibers have good softness, high comfort in use, good antibacterial effect, high hygroscopicity and gelation, and good overall ease of removal. , high oxygen permeability, excellent biocompatibility, and excellent biodegradation and absorption; after the seaweed fiber contacts with wound exudate or blood, it can exchange Na+ / Ca2+ ions with the exudate, release Ca2+, and accelerate the coagulation process. Form a layer of stable mesh gel on the surface of the wound, create a microenvironment (slightly acidic, anaerobic or hypoxic, and moderately humid) for the wound that is conducive to tissue growth, and then promote wound healing; the preparation method is simple in process and mild in condition , low production cost, no pollution to the environment, and environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a superabsorbent medical absorbent cotton gauze and a preparation method thereof. Background technique [0002] Medical absorbent gauze and medical absorbent cotton are the main hygienic materials used in the medical industry for wound dressing, protection, and cleaning of patients. The gauze can promote wound healing of patients, and the gauze has soft texture, low price, wide sources, simple production and processing process, and can be repeated and practical. The fibers in the existing medical absorbent cotton gauze generally have limited water absorption capacity, which cannot provide a moist environment for the wound, which is not conducive to wound healing, and it is easy to cause secondary adhesion of the wound, and in severe cases, it will cause infection. Contents of the invention [0003] Purpose of the invention: In order to overcome the above problems, one ...
