摘要:
The present invention relates to a bunion cushion and particularly, but not exclusively, to a bunion cushion for locating about a toe of the user. The invention provides a bunion cushion (2) comprising a surface having one or more protrusions (42) extending therefrom and which, in use, is placed adjacent the skin of a user of the bunion cushion.

The present invention relates to the use of maleimide derivatives as spermicidal agents. In particular it relates to the use of a maleimide compound of formula (I): wherein R is any group with the proviso that the maleimide is not N-ethylmaleimide, as a spermicide. The invention further provides novel these compounds and their use in medicine. The invention also relates to spermicidal formulations containing maleimide derivatives.

A method of making a rubber latex comprises providing a rubber latex and adding to the latex a solution of a reinforcing agent. Further, a method of making a reinforced rubber latex film comprises providing a rubber latex, adding to the latex a solution of a reinforcing agent, then forming a film from the latex. There is also provided a rubber latex comprising a solution of a reinforcing agent, which is preferably a solution of a water-soluble silicate. Rubber latex films and articles made therefrom are also provided.
摘要:
A water soluble hydrophilic resin in an alcohol-free polymer solution and a method of application to natural rubber and synthetic latex products such as surgeon's gloves, catheters and condoms to increase the lubricity of the rubber products where they come into contact with skin or other tissue. The hydrophilic resin is applied in a single application step in an aqueous solution in the absence of alcohol or a separate acid priming step.
摘要:
A condom for enhanced female stimulation during intercourse (1) is manufactured by a dip moulding process. A conventionally shaped former (10) is dipped into a latex or liquid polyurethane bath and a relatively viscous material is applied by a dispensing gun (11) to form one or more monolithic projections (6). The mandrel may be subsequently dipped into a further liquid bath to sandwich the projections between two layers.
摘要:
A method of forming a thin-walled article comprises coating a roughened former with a first elastomer, which first elastomer substantially does not retain bubbles that may be formed; coating a high modulus polyurethane to the coated former to form the main body of the article; drying and/or curing the composite article; and stripping the composite article from the former, whereby the surface of the first elastomer has a rough surface to provide surface grip. A thin-walled article comprising a grip coating of a first elastomer on a high modulus polyurethane substrate, wherein the coating has a rough surface to provide surface grip is also comprised in the invention.
摘要:
Condoms and similar sheaths are leak tested by being placed over a porous support form (11) referred to as a mandrel similar in shape to the condom, and applying a pressure differential between the outside and the inside of the mandrel, which is preferably hollow. With the open end of the condom sealed in an airtight manner against a smooth surface at the base (17) of the mandrel, leaks are detected by the flow of air or other gas into the mandrel interior.
摘要:
A rubber article (such as a surgeon's glove) is provided with a skin contacting lubricating layer formed from a hydrogel polymer which is a copolymer of 2-hydroxyethylmethacrylate (HEMA) with methacrylic acid (MAA) and/or with 2-ethylhexyl acrylate (EHA) or other alkyl acrylate or alkyl methacrylate. Such hydrogel polymers have improved lubricity to dry skin.
