Abstract: A respiratory therapy device including a housing and an interrupter valve assembly. The housing includes a patient inlet, an exhaust outlet, a chamber, and a supply inlet. The interrupter valve assembly is associated with the housing and includes a control port fluidly connecting the patient inlet and the first chamber, and a valve body adapted to selectively obstruct fluid flow through the control port. In a passive mode, positive fluid flow to the supply inlet does not occur, and the interrupter valve assembly interacts with exhaled air create an oscillatory PEP effect. In an active mode, fluid flow to the supply inlet occurs and the interrupter valve assembly operates to create a CHFO effect. The respiratory device can serve as a passive oscillatory PEP device, and when connected to a positive pressure source, as an active device.

A headrest assembly is removably attached to the head end of the mattress. A roller assembly is disposed in the slots of the mattress. The roller assembly includes base members that are disposed in the slots and also includes ball members upon which a user lies. A vibrating assembly is disposed in said mattress.

Abstract: A strap system is useable with an anesthesia/respiratory face mask having an axially extending gas port connector and a gasket member. The gas port connector has a first diameter, and the gasket member is engageable with and conformable to a face of a patient. The strap system includes a strap member having a first end portion, a second end portion and a middle portion, and a collar. The collar includes an axially extending portion having a second diameter. The strap system includes a strap having a first end portion, and a second end portion; the collar also includes a radially extending portion having at least a first and a second slot through which the first and second end portions, respectively of the strap can pass. The slots are sized for adjustably receiving and fixedly positioning the first and second end portions of the strap.

Abstract: Signals may be generated in a drug delivering apparatus through which a person inhales to generate a inhaled airstream to signal to the person to cease inhalation after a pre-set period of time has elapsed from detection of the commencement breathing by that person. The pre-set period of time for subsequent inhalations is adjusted depending on the time the person takes to stop inhaling after being signalled.

Abstract: An endotracheal tube according to the present invention is used by being installed into a patient so as to use it together with a device having an insertion section which is inserted into the body. A portion overlapping with the device inserted into the patient is formed as a flat shape; and furthermore, an outer face portion formed along a longitudinal direction of a cross-section, of the portion formed in the flat shape contacts the device.

Abstract: An ejection apparatus for ejecting droplets of liquid includes a loading portion, a reader, and a judging unit. The loading portion detachably loads therein a liquid cartridge container for containing liquid, and a liquid ejection cartridge having an ejecting portion for ejecting liquid separately, or as a combined kit. The reader reads information attached to at least one of the liquid cartridge container and the liquid ejection cartridge. The judging unit judges, based on the information read by the reader, whether each of the liquid cartridge container and the liquid ejection cartridge loaded in the loading portion is appropriate, or whether a combination of the liquid cartridge container and the liquid ejection cartridge is a predetermined combination. The ejection apparatus allows a user to relatively readily and accurately carry out ejection of appropriate liquid by an appropriate ejection unit.

Abstract: An improved, pumpless respirator (ventilator) humidifier is provided with a water refilling device (1, 2) and with an electrically heated evaporator (5). The evaporator (5) has a tubular housing, which is filled with a porous sintered material. A front side of the housing is in liquid connection with the automatic water refilling device (1, 2) and the other front side is in connection with an evaporator chamber (4), through which breathing gas flows. The evaporator (5) is provided with a porous sintered glass or ceramic with a pore size of 10 ?m to 40 ?m in a first, lower, unheated area (14), and the evaporator (5) is provided with a porous sintered metal with a mean pore size of 50 ?m to 200 ?m in a second, upper area (15) heated by means of a heater (6).

Abstract: A compressed air respirator with prolonged operating time due to rebreathing. The compressed air reservoir includes a compressed air reserve with a connected demand air supply valve, a reversible breathing gas reservoir (4) with a registering device (5) detecting the filling level of the breathing gas reservoir (4), and with an inspiration and expiration line (7, 8) for the user of the apparatus. A valve (6) is connected with the inspiration and expiration line (7, 8) and, on the inlet side, with the compressed air reserve (1) with a demand air supply valve (2) and with the breathing gas reservoir (4) and, on the outlet side, with the ambient air (11) and with the breathing gas reservoir (4).

Abstract: A hyperbaric oxygen chamber for treatment of large animals such as horses is disclosed. The chamber is large enough for a horse to fit inside and comfortably move around. A specially designed davit door, though quite heavy, is easily manipulated and may be used to corral the horse during ingress or egress, and is serviceable using fluorocarbon lubricants. The door, sidewalls, and floor of the hyperbaric chamber are coated with a static dissipative polyurethane material suitable for oxygen environments and may protect the horse from injury and prevent sparks. The flooring is specially designed to allow the horse to eliminate during treatment, and may be cleaned easily and thoroughly without disassembly. The control mechanisms of the hyperbaric chamber include electro-pneumatic controls, for avoiding a fire hazard.

Abstract: The present invention provides a nebulizing device with a housing that includes a mouthpiece module, an intermediate module, and a base module. An aerosol generator is in communication with a fluid. A barrier is disposed between the fluid and a drug solution provided within the housing. A signal transmitter and a signal receiver are carried by the housing. The signal is either initiated or terminated when one of the modules is separated or misaligned from the other modules. The device further includes a variable volume resilient structure disposed in communication with the fluid to provide volumetric relief in the event that the fluid expands.

Abstract: A breath actuated dry powder inhaler, comprising a substantially disc shaped air circulation chamber for de-agglomeration of entrained powdered medicament using the energy of the inspiratory air stream. The chamber has a substantially circular or polygonal sidewall extending about a central axis between top and bottom walls of the chamber so that the height of the chamber is smaller than its diameter. A plurality of air supply channels disposed about the circumference of the chamber, which channels extend from joint or separate air inlets and which channels enter the chamber substantially tangentially to its sidewall. At least one of the supply channels extends through a powder dose supply region of the inhaler. The chamber further comprises an air outlet axially extending from a discharge opening in the centre of the top or bottom wall of the chamber and connects to a discharge channel that extends to a mouthpiece.

Abstract: An active respiratory therapeutic device for clearing breathing passages, loosening and breaking up mucus plugs and phlegm in a patient's sinuses, trachea, bronchial passages and lungs while a patient is breathing normally through the device is disclosed. The apparatus preferably includes a C shaped curved hollow housing having a closed end portion and an open threaded end portion. The open end portion forms at least part of an acoustic coupling chamber. A generally funnel shaped tapered mouthpiece tapers to a small end portion sized to be inserted into a patient's mouth. The mouthpiece forms another part of the acoustic coupling chamber. An acoustic signal generator housed within the hollow housing generates and directs acoustic vibrations into and through the coupling chamber.
