An allergen and blocking sorbent for topical application to the skin comprising a surface-modified layered material, such as an intercalated clay, dispersed in a cosmetically acceptable solvent. The organic surface modifier is an organic molecule that contains a substantial dipole moment sufficient to bond, through ion-dipole interactions, with an exchangeable cation on the inner surface of adjacent clay platelets. Suitable organic surface modifiers include aldehydes, ketones, carboxylic acids, alcohols, phenols, ethers, catecols, lactams, lactones and pyrrolidones. The preferred layered material useful in this invention includes the entire family of smectite type clays. The composition is topically applied to the skin to absorb or adsorb (hereinafter “sorb” or “sorbent”) via intercalation between spaced layers of the layered material, and block allergenic organic compounds from plants such as poison ivy, poison oak, and poison sumac, thus preventing skin rashes.

The purpose of the present invention is to provide not only the bowl of the toilet, but also the edge of the toilet and the toilet seat in a wide range of bacteria and dirt, and can prevent the sterilizing water from contacting the user's skin and the sterilizing water. A toilet seat device and a toilet device that drip out of the toilet. The toilet seat device includes: a toilet seat; a sterilizing device that generates sterilized water; a spray device that sprays a mist of sterilized water into the toilet; an air supply device that blows air into the toilet; controls the sterilizing device and the spraying device And the control device of the air supply device, the spray device is controlled to execute the first process and the second process at different times, so that the total amount of water mist in the first process is greater than the total amount of water mist in the second process Less, the first step is to make the air blower generate the first updraft that makes the water mist rise to the toilet seat side in the state where the spray device is sprayed with water mist, and the second step is not to make the air blower generate the first updraft. The process of raising the airflow so that the water mist does not rise to the toilet seat side.

A flexible device packaging structure comprises a flexible circuit board and a component arranged on the flexible circuit board, and a gold wire connected with the component and the flexible circuit board is formed between the component and the flexible circuit board. A first packaging layer is arranged on the surface of the component, a second packaging layer is arranged between the first packaging layer and the flexible circuit board, and a third packaging layer is wrapped outside the flexible circuit board; the first packaging layer wraps the component and the gold wire; the second packaging layer is made of a transparent material, and the second packaging layer is formed on the surface of the first packaging layer; the third packaging layer is of a black structure, and when the third packaging layer wraps the flexible circuit board, the top of the component does not make contact with the third packaging layer; compared with the prior art, the black third packaging layer is used on the outer layer in the flexible period, and the upper flexible lining body and the lower flexible lining body are formed by injecting materials into the third packaging layer twice, so that the light loss in the using process is ensured, and the flexible circuit is protected during stretching and bending, and is prevented from being excessively deformed.

The invention discloses a medical brace coated with hydrogel and its preparation method and application. The preparation method comprises: performing swelling treatment on the polymer material brace; placing the swollen polymer material brace on In the polymerization liquid, and initiate polymerization on the surface of the polymer material brace, to form a hydrogel on the surface of the polymer material brace, wherein, the polymerization liquid includes a monomer, a cross-linking agent and a water-soluble initiator, and the monomer is One or more of acrylamide, N,N'-dimethylacrylamide and acrylic acid, the cross-linking agent is N,N'-methylenebisacrylamide, and the water-soluble initiator is I-2925 or persulfuric acid potassium. The preparation method of the hydrogel-coated medical brace of the present invention can form a hydrogel on the surface of the polymer material brace in a coated manner, and the presence of the hydrogel can prevent the brace from directly contacting the skin, thereby The wearing comfort of the brace is improved, and the skin damage of the user is avoided.

A needle tube having a needle tip for puncturing skin; a needle hub; and a fluid-draining portion for enabling draining of a medicine. The needle hub includes: a retention part (first member) for retaining the needle tube; an insertion part into which the output portion of a syringe is inserted; and a flange-like skin contact portion that is disposed in a manner so as to cover an area surrounding the needle tube and makes contact with and / or faces the skin when a living body is punctured with the needle tube. The fluid-draining portion is disposed in the skin contact portion of the needle hub and enables a user to drain the medicine that has spilled when removing air and is held in the skin contact portion.

The present invention relates to the field of disposable sanitary products, in particular to a preparation method of a novel leak-proof trouser-type diaper, which mainly solves the problem of poor comfort of the leak-proof trouser-type diaper in the prior art, and comprises the following steps: 1), preparing Liquid-permeable surface layer; 2), preparing an absorbent core layer; 3), preparing a liquid-impermeable bottom layer; 4), sequentially compounding and connecting the liquid-permeable surface layer, absorbent core layer and liquid-impermeable bottom layer; 5), Prepare the clothing layer: 6), cut the product of step 4 into individual absorbers; 7), combine the bottom nonwoven fabric at the front waist area and the back waist area with the elastic band along the adjacent blank area in the middle 8), the product in step 7 is located between two adjacent absorbers and cut out the trouser legs; 9), the product in step 8 is folded along the central axis of its transverse direction, and The trousers are welded in the transverse direction; 10), the product in step 9 is cut along the middle of the weld.
