Abstract: A control system for a high frequency oscillating ventilator (HFOV) includes and oscillator controller and a mean airway pressure (MAP) controller. The HFOV includes a reciprocating piston which is adapted to generate positive and negative pressure waves for delivery to a patient airway. The oscillator controller comprises a pair of closed loop control circuits including an oscillator pressure loop and a centering loop which are collectively adapted to regulate frequency and amplitude of piston reciprocations and centering of the piston. The MAP controller comprises a closed loop control circuit that is adapted for regulating MAP at the patient utilizing feedback in the form of patient circuit pressure. Likewise, the oscillator controller utilizes patient circuit pressure as well as piston displacement feedback in order to regulate movement of the piston.

Abstract: A gas mask with device for supplying a liquid into the interior space of the gas mask includes a feed tube (6) for drinking liquid that can be fastened to the mask body of the gas mask (3) in a simple manner. A circumferential bead (10) with holes (11), into which a closing plug (8) on the gas mask (3) can be inserted, is provided on the feed tube (6).

Abstract: There is provided a liquid medicine ejection device to eject liquid medicine into an inhalation flow path in the form of liquid droplets, thereby to allow a user to inhale the liquid medicine through a suction portion. In the liquid medicine ejection device is an ejection means, which communicates with a liquid medicine storage section, for ejecting the liquid medicine in the form of liquid droplets from an ejection opening. A pressure variable means changes a pressure in the liquid medicine storage section in accordance with a change of pressure in the inhalation flow path connected to the ejection opening of the ejection means and the suction portion. According to the liquid medicine ejection device of the present invention, it is possible to prevent ejection failure caused by a negative pressure applied to the ejection means, thereby enabling reliable inhalation.

Abstract: The present invention relates to devices and methods for a joint linkage device suitable for training multi-joints in a single limb. The joint linkage device is capable of rotation at a proximal end and a distal end. The device includes a proximal end having an upper plate, a middle plate, and a lower plate, a distal plate, a side bar, a main bar, a switch mechanism, and an extended bar. In use, a torque from a motor is applied to the upper plate to provide a user with an assistance torque, a resistance torque, or a assistance/resistance torque.

Abstract: The present invention provides a pressurized metered dose inhaler (pMDI) system, comprising a transparent or partially transparent canister which permits a patient to view the amount of medicament remaining in the pMDI system. The system of the present also comprises a dose counter which counts a dose when a dose is dispensed. The present invention provides a pMDI system which is improved over those currently used for treating respiratory diseases.

Abstract: A double-body therapeutics face and tracheostomy mask which functions as both a mask for the nose and mouth of a patient and a mask for the tracheostomy tube area of a patient is disclosed. The mask of the present invention serves as a means for delivering a gaseous medicament or a liquid, such as liquid medication, in the form of a fine spray or mist to the nose, mouth, and trachea of the patient simultaneously. The upper body (1) of the mask fits over the nose and mouth area of the patient and the lower body (5) of the mask fits a patient's tracheostomy tube area. The upper and lower mask bodies may be connected to one another and to a nebulizing apparatus (4) and adjustable-length delivery conduit (17). Therefore, the double-body therapeutics face and tracheostomy mask of the present invention may be adjusted to comfortably fit the face and trachea area of any sized patient.

Abstract: A high output, powered air purifying respirator that includes an anti-contamination suit, a filter for filtering particulates from the air, a high powered blower for delivering a cool flow of air to the body, and a stabilization mechanism. The stabilization mechanism is configurable in either head mounted or back mounted modules as desired by a worker. The head mounted configuration facilitates stream lined mobility and includes a head mounted suspension system with a circular rail and roller bearing halo around the worker's head for stabilizing the blower/filter and allowing for rotation of the worker's head inside the halo. The invention also includes additional modules, also configurable by the user, such as personal hydration and independent camera and dosimeter support.

Abstract: The invention relates to a hand-held device for apportioned delivery of sprayable substances, in particular inhaler medicaments the device, having a cartridge which is displaceable by pressing in a housing into the open position for delivery, and an indexing mechanism which is moved along by the cartridge during the opening stroke of the cartridge for registering and displaying delivery actuations which have been carried out. The feeding mechanism, which indexing mechanism is disposed in a housing centrally below the opening-side end wall of the cartridge, overlappinqly with respect to the valve tube of the cartridge. In order to configure a hand-held device of the type in question in a spatially advantageous manner with a simplified construction and such that it is more reliable in terms of handling, it is proposed to displace plate-shaped housing as a whole with the cartridge, except for a step-by-step indexing finger star disposed therein.

Abstract: An emergency oxygen mask includes: a respiration part worn on a user's face for supplying oxygen or discharging carbon dioxide or moisture using a pressure difference depending on respiration of the user; a carbon dioxide supply part for supplying the carbon dioxide and the moisture discharged from the respiration part through a carbon dioxide supply hole at a lower surface of the carbon dioxide supply part; an oxygen generating part engaged with an outer surface of the carbon dioxide supply part and having an upper open surface for reacting potassium dioxide in the carbon dioxide supply part with carbon dioxide or moisture to generate oxygen; an oxygen storage part for storing oxygen moved by an oxygen moving part; and filters attached to opposite sides of the oxygen moving part to remove carbon dioxide remaining in the oxygen stored in the oxygen storage part and to lower the temperature and humidity of the oxygen supplied to the respiration part.

Abstract: An apparatus for high frequency chest wall oscillation (HFCWO) comprises a patient interface which includes an expandable air chamber and an air pulse generator in fluid communication with the patient interface. The air pulse generator includes a variable displacement air chamber and programmable controller which controls the air pulse generator to vary the frequency and volume of air pulses delivered to the patient interface such that HFCWO therapy may be programmed for a particular patient.

Abstract: An inhalant dispenser has a cover 3 pivotally carried on a body 6. The cover has a cam arrangement for lifting a junction member 41 against the action of the spring in an inhalant can C. Lifting of the junction member cocks a breath actuated dose release mechanism. The latter includes a flap 61 in the breath path. The flap is carried on the junction member and is arranged to release a hinged member 48 by action of latches 70 on the flap and sears on the hinged member.
