Abstract: A method of tooth treatment includes sensing a surface condition of tooth or gum and controlling ejection of a fluid jet against the tooth based on the sensed condition. The fluid may be a liquid and may be carried in a self-contained reservoir in a handle of a fluid ejection device. The liquid can be a cleansing solution and may contain cleaning particles. The ejection can be controlled to clean teeth at high pressure and to reduce pressure applied to gum, for example, to clean plaque. In some embodiments, the method may be used to remove soft tooth. The method may further include automatically scanning the fluid jet relative to a handle of an injection device. In an embodiment, the fluid is ejected by means of a fluid ejector comprising a stationary magnet assembly providing a magnetic field and a coil assembly, slidably disposed with respect to the magnet assembly, the coil assembly driving ejection of the fluid jet.

Abstract: The invention is directed to a positive airway pressure (PAP) system with a head mounted harness assembly with a housing and a head position sensor located within or secured to the housing that detects the position of a patient's head, and communicates this head position information to a controller of the system which may be disposed within the housing having the position sensor or a second housing. The controller varies the output pressure of the pressure source e.g., a rotary compressor, based, at least in part, on the head position information provided by the head position sensor. In a preferred embodiment, the position sensor is an accelerometer.

Abstract: Disclosed is a device for respiratory assistance and a measurement system that includes the device. The device includes a tube, which forms a main channel, and at least one auxiliary channel connected to a source of respiratory gas. The device further includes a unit by which vitiated gas, exhaled by a patient, is removed from the patient between a distal end of the auxiliary channel, which opens into the main channel, and a distal end of the main channel, and which is configured to capture and remove the exhaled gas, undiluted by insufflated fresh respiratory gas.

Abstract: An oral device is disclosed. The oral device comprises a mouthpiece member, a tube member and an attachment member. The mouthpiece member comprises a resilient material, and is adapted to fit within the contours of the teeth of a wearer. The tube member is affixed, at a first end, to the mouthpiece member, and extends outward from the mouthpiece member towards the soft palate of the mouth of the wearer. The attachment member is attached to the mouthpiece member at at least one location. Finally, the tube member defines an opening, which prevents the collapse of the soft palate of the wearer by allowing for the free transfer of air between the wearer and the environment.

Abstract: There is provided a liquid formulation ejection device which improves reliability of inhalation even in a case where a preejection is performed and resolves a concern about hygiene. The liquid formulation ejection device (1) ejects a liquid formulation in a form of liquid droplets into an inhalation flow path (20) and allows a user to inhale the formulation. The liquid formulation ejection device (1) includes an ejector (11) for performing normal liquid droplet ejection for inhalation and liquid droplet preejection not for inhalation, and a discharger (13, 14, 28) for removing liquid droplets ejected by the liquid droplet preejection out of an inside of the inhalation flow path (20).

Abstract: A dose counter mechanism is suitable for use with a medicament delivery device. The dose counter mechanism comprises a rollable tape (20) provided with indicia (22), a tape housing (10) and a tape collector spool (40). The tape housing comprises a tape dispenser housing (14) within which, in use, a roll (24) of the tape is inserted and a tape collector spool housing (16) within which, in use, the tape collector spool is mounted. The tape dispenser housing and the tape collector spool housing are connected by a tape display area (15).

Abstract: An apparatus for delivering humidified gases has a connection manifold adapted to connect with inlet and outlet ports of a slide on water chamber in a single slide on motion. Connection of the gases inlet and gases outlet ports as well as any additional electrical and/or pneumatic connections are all made in the same slide on motion. The water chamber may include inwardly extending elongate extension tubes with one of the extension tubes having an air bleed aperture to aid filling of the chamber.

Abstract: A control valve is fluidly coupled to chambers containing fluid of different pressures for regulating flow therebetween. The control valve has a valve housing having a chamber fluidly coupled to a first chamber, a second chamber, and a third chamber. A fluid flow regulation member is disposed in the chamber and is configured to regulate fluid flow between the second chamber and the third chamber. A diaphragm is disposed substantially perpendicular to a longitudinal axis of the chamber in which longitudinal deflection of diaphragm is representative of the pressure in the first chamber.
