Patent number: 11351316Abstract: A handheld device for dispensing a pharmaceutical substance has a housing in which a storage container with the pharmaceutical substance and a counter are arranged. The storage container dispenses the pharmaceutical substance by pressure actuation by a user after a specified displacement path has been traversed, and the counter carries out an action in order to rotate a counter wheel of the counter on the basis of the displacement path being traversed. The counter additionally has a drive part rotates the counter wheel, and the counter wheel is rotatably attached to a mounting part. The mounting part is formed independently of the housing, and the drive part is directly attached to the mounting part. The handheld device advantageously dispenses a pharmaceutical substance in that the action is first carried out on the counter wheel of the counter upon the pressure actuation, and the pharmaceutical substance is then dispensed.Type: GrantFiled: April 5, 2017Date of Patent: June 7, 2022Inventor: Alfred Von Schuckmann

Patent number: 11273278Abstract: Components for a respiratory treatment apparatus that is capable of providing a humidified respiratory treatment permit a reduction in condensation in a patient interface and/or its gas delivery tubing. In some embodiments, a rainout valve that may be an integrated component of a humidifier output aperture, or coupled thereto, may reduce condensation with a vapor barrier operable to selectively block and permit humidified gas transfer from the humidifier. For example, the barrier may be operable to open in response to a flow of pressurized breathable gas that may be generated by a flow generator of the respiratory treatment apparatus. In the absence of such a generation of pressurized flow, the barrier may prevent a transfer of the humidified gas such as into a conduit for a patient interface by retracting to a closed position. Example vapor barriers may include a resilient membrane, cover, bellows, flap, shutter or other suitable valve.Type: GrantFiled: August 22, 2018Date of Patent: March 15, 2022Inventors: Gordon Joseph Malouf, Liam Holley, Paul Jan Klasek
