    Abstract: A patient interface device includes a bladder assembly having a headgear bladder member, a nose bridge bladder member, and a connecting tube member provided between the headgear bladder member and the nose bridge bladder member. The headgear bladder member is in sealed fluid communication with the nose bridge bladder member through the connecting tube member, and is filled with a fluid medium. The bladder assembly is structured such that the nose bridge bladder member will be inflated as a pressure on the headgear bladder member increases and such that the nose bridge bladder member will be deflated as the pressure on headgear bladder member decreases. Inflation of the nose bridge bladder member causes the top of a cushion member to move toward the patient's nose bridge, and deflation of the nose bridge bladder member causes the top of the cushion member to move away from the patient's nose bridge.

  • Patent number: 8393324
    Abstract: The present invention provides a symmetrical face mask suitable for use with one hand that allows an operator to provide a reliable seal with the patient's face with his/her hand and arm in an anatomically favorable position for application of a user's physical strength. In general, a user may reach at an acute angle to the plane of their chest and engage the invention mask with their hand in a manner the user may shake another person's hand, i.e., with a distal portion of their radius and ulna arranged essentially vertically so that side to side motion of the hand translates to forward and rearward motion of a mask shell while a user reserves full bi-directional rotational capability of their arm for forward or rearward rotation compression of the mask shell while, at the same time, reserving full and lever-efficient, bi-directional pushing and pulling range of a user's arm for greater pressure of the mask shell to a right or left side of a user's fleshy cheek.

  • Patent number: 8360062
    Abstract: A mask assembly includes a mask with an inflatable bladder. The internal pressure of the inflatable bladder can be set to be higher than the delivered therapeutic pressure. The pressure offset may be constant, or it may vary over the range of therapeutic pressures. Thus, the force necessary to maintain a contact seal between the mask and the patient can be reduced, thereby providing a system that is more comfortable to the patient, which increases patient compliance.

  • Publication number: 20120318271
    Abstract: A kit for fitting a patient interface device (10) to the naris of a patient. The patient interface device employs a replaceable nasal pillow (46). The kit comprises a plurality of nasal pillows each having a characteristic that varies from one of the plurality of nasal pillows to another of the plurality of nasal pillows. Each of the nasal pillows comprises a base portion (62), a casing (65) and a fill material (66). The base portion is structured to be disposed on a portion of the patient interface device. The casing is coupled to the base in a manner which defines a sealed cavity therein. The casing includes an outer portion (65) structured to sealingly engage a naris of a patient and an inner portion (67). The fill material is disposed in the sealed cavity defined by the casing and the base.

  • Patent number: 8312882
    Abstract: Disclosed is an artificial respiration device that includes a tubular element, which forms a main channel having an upstream part at the proximal end of the tubular element and a downstream part at the distal end of the tubular element. Auxiliary channels open into the main channel and deflecting means are located internal to the main channel. The deflecting means are configured to deflect jets of respiratory gas injected into the main ckannel through the auxiliary channels so as to converge the gas at a point of convergence inside the main channel. The tubular element also includes at least one lateral safety orifice that extends through a lateral wall of the tubular element at a location sustantially opposite the point of convergence, and which is configured to communicate air from outside the tubular element to the downstream part of the main channel.

  • Patent number: 8276587
    Abstract: A hand-held, automated qualitative fit tester (QLFT) for establishing gas mask fit integrity. The automated QLFT may be configured to utilize a pressure source in combination with a cartridge and a nebulizer to generate aerosols having size distributions and concentrations that are substantially the same as OSHA-approved manual units. The QLFT may further include a cartridge that contains the aerosol solution used to test mask integrity. The cartridge may be configured to recapture solution that collects on the interior walls of the nebulizer. The automated QLFT may also be equipped with a microprocessor for executing sequences that are in substantive compliance with 29 CFR 1910.134 and for writing to a data storage device. The automated aspects of the invention can reduce or negate the need for operating personnel to repeatedly and manually actuate a squeeze ball and record results manually, as is required with present OSHA-approved hand-held aerosol generators.

  • Patent number: 8276588
    Abstract: This invention is a respiratory mask for delivering pressurized gas with a perimeter that can be custom fitted to the contours of a person's face by active and individual adjustment of multiple shape-changing members in the body of the mask. In different embodiments of this invention, the shape-changing members may be located around the perimeter of the mask and individually adjusted by inflation, other pneumatic means, hydraulic means, electric means, or magnetic means. The resulting mask can conform to the contours of an individual's face, even while they sleep, so that there are no places around the mask that fit too tightly (causing irritation, skin marks, and pain) and no places that fit too loosely (causing air leaks).
