Problems solved by technology

The disadvantages of natural fiber materials are: poor sealing, unable to maintain appropriate humidity, so it is easy to bond with the wound surface, and its advantages are drainage and adsorption of toxic substances; the disadvantages of hydrophilic polymer materials The advantages are: no drainage, no adsorption of toxic substances, the advantages can keep a certain degree of humidity on the wound surface, and good sealing; the disadvantages of biopolymer compounds are: no drainage, no adsorption of toxic substances, the advantages can be maintained Certain humidity, good sealing, and beneficial to promote wound healing
The common shortcomings of the above three materials are: small absorption capacity, poor disinfection and infection resistance
However, materials such as puffed paper and polymer water-absorbent resin have a small amount of absorption of blood, secretions, etc., and the absorption speed is slow.

Embodiment 1

[0022] This embodiment is described by taking sanitary napkin as an example.

[0023] Such as figure 1 As shown, the sanitary napkin includes a surface layer 1, an absorbing layer 2, and a bottom layer 3. The absorbing layer 2 is a human body liquid substance absorbing material, and the human body liquid substance absorbing material has a layered structure, and its components include polymer resin, activated carbon , slaked lime, cotton pulp. The weight ratio of each component is 15% of activated carbon, 5% of slaked lime, 10% of cotton pulp and 70% of polymer resin.

[0024] Certainly when implementing, the weight ratio of each component also can have different selections, as following three groups:

[0025] Activated carbon 10%, slaked lime 5%, cotton pulp 5%, polymer resin 80%;

[0026] Activated carbon 30%, slaked lime 18%, cotton pulp 9%, polymer resin 43%;

[0027] Activated carbon 50%, slaked lime 30%, cotton pulp 15%, polymer resin 5%.

[0028] The following is a ...

Embodiment 2

[0033] In this embodiment, the wound dressing is taken as an example for illustration.

[0034] The wound dressing in this embodiment comprises two layers, respectively a backing material and an absorbent material. The absorbent material is a human body liquid substance absorbent material, which has a layered structure, and its components include polymer resin, activated carbon, and slaked lime. 1. Cotton pulp, the weight ratio of each component is 30% of activated carbon, 18% of slaked lime, 9% of cotton pulp, and 43% of polymer resin.

[0035] Certainly when implementing, the weight ratio of each component also can have different selection, as following two groups:

[0036] Activated carbon 10%, slaked lime 5%, cotton pulp 5%, polymer resin 80%;

[0037] Activated carbon 50%, slaked lime 30%, cotton pulp 15%, polymer resin 5%.

[0038] The following is a brief description of the production process of the human body liquid substance-absorbing material. The process in this e...

Abstract

The invention discloses a liquid matter absorbing material for human bodies and a sanitary towel and a wound dressing prepared by the liquid matter absorbing material. The components of the liquid matter absorbing material for human bodies comprise macromolecular resin, active carbon, white lime and cotton pulp. The liquid matter absorbing material for human bodies can be used as the materials for manufacturing the sanitary towel and the wound dressing. As the invention comprises the four components of the macromolecular resin, the active carbon, the white lime and the cotton pulp, wherein, the macromolecular resin has excellent seal performances and can lead a contact surface to maintain proper humidity after absorbing water; the cotton pulp has the effect of flow conduction; the white lime has the effects of stanching, sterilizing and resisting infection; the active carbon and the cotton pulp can absorb poisonous matters; and the four components all have the absorption effect, thereby the absorption amount is large. The comprehensive effects of the four matters can improve the absorption speed; therefore, the invention can solve the problem existing in the existing liquid matter absorbing material for human bodies.

Description

technical field [0001] The invention relates to health care products, more specifically to a human body liquid substance absorption material and a sanitary napkin and a wound dressing made of the same. Background technique [0002] The human body fluid substances we are talking about here mainly include two types, one is the liquid produced by human body wounds, including blood and inflammatory secretions; the other is the normal secretions of women, including menstruation and leucorrhea. Wound dressings for dealing with human body wound effluent include two layers, namely backing material and absorbent material. The backing material mainly plays a role in shaping the absorbent material. Currently, there are three main types of absorbent materials used for wounds, natural fiber, Such as gauze; hydrophilic polymer materials; biopolymer compounds. The disadvantages of natural fiber materials are: poor sealing, unable to maintain appropriate humidity, so it is easy to bond wit...
