  • Patent number: 10905837
    Abstract: A respiratory device includes a blower having an inlet and an outlet, a patient interface, and a valve including a valve member that is rotatable through a first angular displacement in a first direction from a first position to a second position. The outlet of the blower is coupled to the patient interface so that positive pressure is provided to a patient's airway via the patient interface when the valve member is in the first position. The inlet of the blower is coupled to the patient interface so that negative pressure is provided to the patient's airway via the patient interface when the valve member is in the second position. The valve member is rotatably oscillated back and forth when the valve member is in the first position and when the valve member is in the second position so that oscillations in the positive pressure and negative pressure, respectively, are provided to the patient's airway.

  • Patent number: 10331853
    Abstract: A method of indicating an oxygen desaturation period has been initiated includes detecting an oxygen mask configured to supply oxygen to a patient to saturate the patient, detecting a removal of the oxygen mask from the patient to stop saturation of the patient, initiating a desaturation timer in response the removal of the oxygen mask from the patient, and operating an image display device to display a first running time on a screen of the image display device indicating a desaturation time elapsed from a time of the removal of the mask.

  • Patent number: 10307217
    Abstract: A mask suitable for protecting the face of a patient during surgery comprises a transparent plastic shield which includes a transverse cutout that provides access to the nose and mouth, and a vertical gap which runs from the cutout to the shield's perimeter. Padding affixed to the perimeter of the shield's underside provides a cushion between the shield and face. The padding is preferably arranged such that the mask can be installed or removed without dislodging tubing inserted into the patient's nose or mouth via the transverse cutout. An attachment mechanism secures the shield to the face. A warming hood may be coupled to the protective mask. The hood preferably comprises outer and inner layers, with an access point at which air can be introduced between the layers; perforations on the inner layer permit warm air to be dispersed onto the patient.

  • Patent number: 10272216
    Abstract: It is a support mask with a mounting strip to the head of the user. Inside the mask, the actuating mask is fixed with its vapor inlet tube connected, removable, with the injector tube of an external receptacle where a micro compact removable nebulizer is set up. The micro nebulizer has a micro ultrasonic cavitation microsystem capable of generating the vibrations necessary to vaporize the medicated liquid contained in a built-up tank. That ultrasonic mechanism is activated by a small electronic device with an activation button that is housed in a side enclosed area and is powered by batteries inside a similar battery enclosed area on the opposite side. The external surface of said support mask, presents, in strategic places, fixation means to enable an external party face mask of a laminar material molded similar to those characters admired by children.

  • Patent number: 10174870
    Abstract: A hose which automatically expands longitudinally and automatically expands laterally upon the application of a pressurized liquid is disclosed. The hose can automatically expand longitudinally up to six times its unexpanded or contracted length. Upon release of the pressurized liquid within the hose, the hose will automatically contract to a contracted condition. The hose includes an inner tube made from an elastic material and an outer tube made from a non-elastic material. The inner tube is positioned concentrically within the outer tube in both a contracted condition and an expanded condition. The outer tube is secured to the inner tube only at a first end of the inner and outer tubes and at a second end of the inner and outer tubes. The outer tube moves laterally and longitudinally with respect to the inner tube when the tubes are transitioning between a contracted condition and an expanded condition.
