  • Patent number: 11945935
    Abstract: The present disclosure relates to methods for preparing a hydrophilic composition including intimately mixing a silicone component including at least one polysiloxane and a polymer component, and to hydrophobic polymer compositions prepared thereby. One aspect of the disclosure provides an article having a major exterior surface, the article comprising an intimate mixture of a silicone component including at least one polysiloxane; and a polymer component including at least one hydrophilic polymer having a water-absorption capacity of at least 50 wt. %; wherein the silicone component and the polymer component are present in the mixture in a dry weight ratio within the range of 99.9:0.1 to 30:70. In certain desirable embodiments as otherwise described herein, the intimate mixture is disposed at an exterior surface of the article, e.g., at the major exterior surface of the article.

  • Publication number: 20100234815
    Abstract: In a medical device having an antimicrobial agent, the medical device includes a base material and an amount of chlorhexidine or a pharmaceutically acceptable salt thereof disposed in the base material sufficient to reduce microbial growth. The base material is melt processed together with the chlorhexidine to generate the medical device which is substantially free of destabilized chlorhexidine.

  • Publication number: 20070298759
    Abstract: An alarm device for a mobile phone includes a receiver for receiving a signal transmitted from a transmitter of a mobile phone only if the receiver is located within a predetermined distance from the mobile phone, an alarm unit for generating an alarm signal, a timing circuit for measuring a predetermined time duration and triggering the alarm unit upon elapse of the predetermined time duration, and a microprocessor for prestoring a subscriber identification module number therein, checking if the mobile phone identification number contained in the signal received by the receiver is identical with the prestored subscriber identification module number, and resetting the predetermined time duration of the timing circuit if the mobile phone identification number contained in the signal received by the receiver is identical with the prestored subscriber identification module number.
