Abstract

The invention relates to the technical field of medical materials, in particular to a medical dressing core. The medical dressing core comprises needle-punched non-woven fabric; the needle-punched non-woven fabric is not compounded or compounded with an isolation membrane at one side or each of two sides; the isolation membrane(s) and the needle-punched non-woven fabric are thermally compounded, and the compounding temperature is 120-125 DEG C. The medical dressing core is made of viscose fibers and polyester fibers, is soft and breathable and has good absorbability and softness; a special polyethylene grid thin layer on the surface of the medical dressing core can effectively prevent a dressing from adhering to the edge of a wound, and pain cannot be caused when the dressing core is removed or replaced; and the medical dressing core cannot cause allergy, skin irritation or cytotoxicity to a human body, can effectively prevent wounds from being infected by bacteria, has relatively high absorption performance, meets the national hygienic standard, and is an ideal absorbent material of a new-generation series medical dressing product.

Description

technical field [0001] The invention relates to the technical field of medical materials, in particular to a medical dressing core. Background technique [0002] Medical wound dressing plays the role of temporary bandage to stop bleeding, control wound exudate, isolation protection, antibacterial and anti-inflammatory, and promote wound healing. Due to its convenient use and reduced wound care workload, it is more and more popular among medical workers and patients . [0003] The softness and air permeability of existing medical dressing cores need to be improved, and some medical dressing cores may cause skin allergies to sensitive people. Contents of the invention [0004] In order to solve the above problems, this product provides a medical dressing core with better absorbency and softness. [0005] The purpose of the present invention can be achieved through the following technical solutions: a medical core, including needle-punched non-woven fabric, the needle-punch...
