Abstract: A fitting for coupling to a pipe includes a sleeve for receiving the pipe and a sealing member to provide a seal between the sleeve and the pipe. A pressure ring acts on a pressure member through adjoining slanting contacting surfaces of the pressure ring and pressure member, respectively. The sealing member is configured to be displaced from the slanting contact surfaces to preserve the life of the seal.

Abstract: The invention provides forced air warming apparatus for providing air to a patient temperature regulation tool for regulating the temperature of a patient, the forced air warming apparatus comprising: a housing; an air pressurising device provided within the housing, the air pressurising device being configured to receive an air intake and to pressurise air from the air intake; and a suspension configured to restrict transfer to the housing of vibrations caused by the air pressurising device pressurising the said air from the air intake.

Abstract: A fitting for coupling to at least one pipe, comprising: a sleeve for receiving the pipe; at least one sealing member to provide a seal between the sleeve and the pipe; a pressure member for applying a pressure to the sleeve and to the pipe; gripper teeth provided on the pressure member and arranged to act on the pipe; and actuation means for exerting a pressure to the pressure member comprising a pressure ring acting on the pressure member through adjoining slanting contacting surfaces of said pressure ring and pressure member, respectively; wherein the at least one sealing member is positioned between the pressure member and the pipe; wherein the at least one sealing member is connected with or pressed against the sleeve without being positioned between the pressure member and the sleeve.
