Abstract: A first antimicrobial latex composition comprising a homogeneous blend of a natural rubber latex or a synthetic polymer latex and protein silver and a second antimicrobial latex composition comprising a homogeneous blend of a cationic natural rubber latex or a cationic synthetic polymer latex and a water-soluble silver compound, wherein each antimicrobial latex composition exhibits excellent long term stability during storage and can be readily prepared.

Abstract: A bladder assist device for maintaining natural drainage by a repetition of expansion and contraction of a bladder even when a urethral catheter is embedded in the bladder which includes a pressure control chamber containing a concentric-type siphon tube connected to a urethral catheter at a particular part, the pressure control chamber having a pressure control hole sealed by an air flow restricting filter.

Abstract: An antimicrobial latex composition is disclosed. The antimicrobial latex composition comprises (1) at least one cationic latex component selected from a cationic natural rubber latex and a cationic synthetic polymer latex and (2) a cationic antimicrobial agent incorporated in said cationic latex (1). The resulting composition is antimicrobial latex compositions suitable for use in the manufacture of medical devices and appliances, sanitary products, equipment and furnishings for use in food manufacture and processing, and so forth, in particular antimicrobial latex compositions retaining good stability over a long period of storage.
