  • Publication number: 20240139476
    Abstract: A securement device (1) for securely attaching tubular articles to surfaces comprising an anchor pad (3) for placing the securement device (1) on the surface, a substantially cylindrical base (4) on the anchor pad (3) and a screw cap (5) rotatably mountable on the base (4) at a screw mounting (6) defined between the base (4) and the screw cap (5) between an article receiving position and an article gripping position in which radial pressure is applied to the article placed in the securement device (1) to securely hold the article without the use of external adhesive fixings and prevent micro-pistoning of the article.

  • Patent number: 11951253
    Abstract: A positive exhalation pressure device (1) is described. The device (1) comprises a housing (2) having an annular chamber (5), a chamber inlet (6) configured to permit air into the chamber, a chamber outlet (7) configured to permit air out of the chamber, and a mouthpiece (8) in fluid communication with the chamber inlet. A movable body such as a ball (3) is disposed in the housing within the annular chamber and configured to revolve around the annular chamber in response to flow of air through the chamber from the chamber inlet to the chamber outlet. The movable body is configured to at least partially block the chamber outlet as it revolves around the annular chamber causing cyclical fluctuations in airflow resistance.
