Abstract: An intra vaginal device (10) including an elongated hollow body (11) with side wall portions (15, 16 and 24). Secured to each wall portion (15 and 24) is a sensor (19), while secured to the wall portion (16) is a sensor (20). The sensors (19) simply measure forces directly applied by the bi-lateral contraction of the pubococcygeus, while the sensor (20) provides an indication of the puborectalis contraction forces.

Abstract: A blower assembly is configured to deliver a flow of breathable gas at a continuously positive pressure with respect to ambient air pressure to a patient interface in communication with an entrance to a patient's airways including at least an entrance of the patient's nares, while the patient is sleeping, to ameliorate sleep disordered breathing. The blower assembly includes a motor having a shaft that extends from opposite sides of the motor. The blower assembly also includes an impeller and a circuit board. The impeller is attached to the shaft on a first side of the motor and is structured to rotate in close proximity to a volute wall. The circuit board is configured to control power supplied to the motor and is configured to disable the motor when the impeller is closer than a predetermined distance from the volute wall.

Abstract: A multiple stage variable speed blower for Continuous Positive Airway Pressure (CPAP) ventilation of patients includes two impellers in the gas flow path that cooperatively pressurize gas to desired pressure and flow characteristics. Thus, the multiple stage blower can provide faster pressure response and desired flow characteristics over a narrower range of motor speeds, resulting in greater reliability and less acoustic noise.

Abstract: A burette (10) to receive liquid from an intravenous supply (29) to deliver liquid to a patient via a tube (30). The burette (10) includes a hollow body (11) that is generally cylindrical configuration and that contains a float valve (24). Liquid level in the chamber (12) of the body (11) regulates liquid level within the chamber (12) by engaging an inlet passage (36) or an outlet tube (25).

Abstract: The combination (10) of a burette (11) and injection portion (20) and a tube (21) to be connected to a reservoir to drain a liquid therefrom for delivery to the burette (11). The injection port (20) is fixed to a cap (16) of the burette (11) by having an outlet (28) extending to and being secured to an inlet (19) of the burette (11).
