Debridement health dressing

Technical Field

The utility model relates to the technical field of functional dressings of medical equipment, concretely relates to debridement health care dressing.

Background

Medical dressings refer to medical materials used to cover sores, wounds, or other lesions. The skin is injured by wound, burn, abscess and ulceration, which can cause a series of problems of the body, such as bacterial infection, excessive loss of water and protein, endocrine and immune dysfunction and the like, and can seriously endanger life. Therefore, after skin injury, a medical dressing which is a substitute for skin is generally needed to protect wounds, prevent wound infection and severe dehydration, provide a moist environment which is beneficial to wound healing, and promote wound healing.

The skin care dressing disclosed by the prior art mainly comprises collagen peptide, chitosan, benzoic acid, methyl paraben, potassium sorbate and the like, wherein the preservatives benzoic acid, methyl paraben and potassium sorbate have certain stimulation on UV-damaged skin and are not beneficial to fading red and swollen and recovering wound surfaces; lie, Ma et al (Ma L, Gao C, Mao Z, et al. Collagen/dental tissue dressings with improved biocompatibility for skin care J. Biomaterials, 2003, 24(26): 4833-4841.) use the toxic agent glutaraldehyde as a cross-linking agent to improve the mechanical properties and functional structure of skin dressings. For example, patent application No. N201310463753.1 discloses the use of aldehydes as cross-linking agents to improve the performance of chitosan gel dressings, wherein glutaraldehyde residues and cross-linked in carboxymethyl chitosan are difficult to remove, causing some damage to cell proliferation and migration; meanwhile, the inflammation reaction of the wound is aggravated, secondary damage is caused to collagen in the dermis, and the healing of the damaged skin is not facilitated.

At present, the theory of wet healing of wounds is gradually accepted and accepted by people, and the wet wound dressing has the following functions: the wound was kept at a constant temperature (37 ℃); the contact surface of the dressing and the wound needs to keep certain humidity; can absorb excessive exudates; the paint has good permeability; preventing microorganisms, harmful particles and other harmful substances from polluting the wound; the dressing is removed without damaging the wound. However, the existing dressing has more or less certain defects in the aspects of absorbing liquid, preserving moisture, protecting wounds and promoting wound healing when the dressing is used for nursing the wounds.

Disclosure of Invention

The utility model aims at providing a debridement health care dressing which controls and absorbs exudates, moisturizes, debrides and promotes wound healing in order to improve the defects of the current moist wound dressings.

In order to solve the above problem, the utility model adopts the following technical scheme:

a wound-cleaning health dressing comprises a stripping layer, a dressing layer, a liquid-absorbing and moisture-keeping layer, an adhesive layer and a health-care layer; the dressing layer is in a round table shape, and the lower half part of the dressing layer is embedded by the liquid absorption moisturizing layer; the health care layer completely covers the liquid absorption and moisture retention layer; the adhesive layer is silicone gel and is coated on the periphery of the health-care layer.

Preferably, the stripping layer is glassine silicone oil paper, and the gram weight of the glassine silicone oil paper is 40-90g/m²。

Preferably, the liquid-absorbing and moisture-preserving layer is porous hydrophilic polyurethane foam.

Preferably, the adhesive layer is silicone gel and is coated around the health-care layer.

Preferably, the dressing layer is a blended yarn of antibacterial fibers and bamboo fibers.

Preferably, the health care layer is a negative ion far infrared chip.

Preferably, the release layer may completely cover the health care layer.

Preferably, the dressing layer and the liquid absorption and moisture retention layer as well as the liquid absorption and moisture retention layer and the health care layer are tightly bonded through soft tissue medical glue.

The antibacterial fiber is prepared by mixing multiple natural mineral ions such as zinc ion (Zn)²⁺) Copper ion (Cu)²⁺) Silver ion (Ag)⁺) And titanium dioxide (TiO)₂) In the spinning process, the antibacterial agent is uniformly embedded into the fibers and is integrated with the fibers, so that the antibacterial agent does not fall off or dissolve out in the use process, and the aim of long-acting antibiosis is fulfilled. Based on the original antibacterial property, the cross section of the fiber adopts fine denier multimerization and polytropismThe surface body has a special-shaped structure, the surface area of the fiber is increased, so that a capillary effect and a siphon phenomenon are generated, and the moisture absorption and quick drying functions are realized.

The bamboo fiber is cellulose fiber extracted from naturally growing bamboos, has the characteristics of good air permeability, instant water absorption, strong wear resistance, good dyeing property and the like, is soft and smooth in hand feeling and good in skin friendliness, and has the functions of natural antibiosis, bacteriostasis, mite removal, deodorization and ultraviolet resistance.

The hydrophilic polyurethane foam structure has a three-dimensional porous structure, and can effectively maintain the moist environment on the surface of a wound. The hydrophilic property and the porous structure can quickly absorb the exudate on the surface of the wound and prevent the wound from being soaked in the exudate. When the liquid enters the pores, the liquid has water retention property, namely, the water is not easily extruded under the pressure condition, and a moist environment is provided for the wound.

The utility model discloses following beneficial effect has:

(1) the dressing layer in direct contact with the wound has natural antibacterial, bacteriostatic and mite-removing functions, so that the use safety of the dressing is improved, and the storage life of the dressing is prolonged;

(2) the dressing layer greatly increases the antibacterial effect of the dressing layer by combining the two antibacterial fibers, and protects the wound from infection;

(3) the dressing layer has certain hygroscopicity, and meanwhile, the dressing layer in the round table structure is combined with the liquid absorption and moisture retention layer matched with the dressing layer, so that absorbed seepage can be guided and diffused to the liquid absorption and moisture retention layer on one hand, and the moisture retention of the dressing is greatly enhanced; on the other hand, the dressing layer is not easy to slide out of the liquid-absorbing and moisture-preserving layer;

(4) the anion far infrared chip layer can be used for producing anions, has the effects of stabilizing nerves and relieving pain, improves the comfort of the dressing in wound nursing, and has certain health care and wound healing promotion effects.
