  • Patent number: 8677997
    Abstract: A method and CPAP apparatus characterizes different mask systems, e.g., masks and hoses. The CPAP apparatus can be calibrated for different mask systems and hoses by including sensors that measure flow and pressure at a flow generator of the apparatus. When the generator is fitted to a new mask system, or any changes are made to an existing one, a method calibrates the generator for the mask system. The method includes determining air flow characteristics using flow measurements from a first test period when flow through the mask system is open, measuring or estimating pressure in the mask system during a second test period when flow through the mask system is blocked and determining air flow characteristics of the diffuser of the mask system using the air flow characteristics of the air delivery hose determined during the first period and the pressure measurements made during the second period.

  • Patent number: 8640701
    Abstract: A system and method of providing bi-level CPAP therapy is provided that incorporates an infrared carbon-dioxide sensor to determine whether a patient is inhaling or exhaling. Patient exhalation causes the infrared light to be absorbed, while patient inhalation reduces the presence of carbon-dioxide causes little or no absorption of carbon-dioxide. The level of carbon-dioxide in an associated patient breathing interface is monitored for thresholds that trigger higher CPAP pressure upon inhalation and lower CPAP pressure upon exhalation.

  • Patent number: 8584676
    Abstract: A breath responsive filter blower respirator system for a gas mask including a pressure and control device, such as an optoelectric device and/or a pressure sensor, to control the air flow produced by an air blower. The optoelectric device detects the position of the mask's outflow valve. The pressure sensor measures air pressure in the mask relative to ambient air or the absolute air pressure in the mask. During exhalation, the pressure detector detects an increase in air pressure in the mask and/or the optoelectric device detects the outflow valve in an open position, and then signals the central processing unit to signal the air blower to reduce speed. The reduction in speed reduces air flow in the mask and lowers air pressure in the mask.

  • Patent number: 8479742
    Abstract: Medical devices and related methods are disclosed for delivering an implant into the body of a patient. The devices include a damping assembly having an internal chamber with a varying inner diameter, and a piston slideably disposed therein. The piston is operably connected with a catheter portion such that movement of the piston is associated with concurrent movement of the catheter for implant delivery. The varying inner diameter of the damping assembly results in a decrease in damping force during implant delivery, thus providing a substantially constant velocity of implant delivery.

  • Patent number: 8479731
    Abstract: A method and apparatus for determining the presence or absence of a pulmonary embolism (PE) in a patient. The breathing gas CO2 partial pressure (PCO2) during the expiration of breathing gases by the patient, the end tidal (EtCO2), CO2 partial pressure, and the CO2 partial pressure (PaCO2) of the blood are measured. The volume (V) of breathing gases expired during the expiration of breathing gases by the patient is also measured and a relationship between changes in breathing gas CO2 partial pressure (PCO2) and changes in breathing gas volume (V) in an alveolar expiration phase of patient expiration is determined. The difference between the blood CO2 partial pressure (PaCO2) and the end expiration CO2 partial pressure is divided by the relationship between PCO2 and V produce a quantity which is compared to a threshold value. If the quantity is below the threshold value, the absence of a pulmonary embolism is indicated.

  • Patent number: 8435201
    Abstract: A method for treating a user's back, a user's neck, or combinations thereof. The method can include the steps of: inserting a traction device into a pouch of a fabric garment; disposing the fabric garment over a user; engaging the traction device with a surface; and applying a pressure to the traction device using the user's back. The traction device can provide a therapeutic pressure to the user's back, to the user's neck, or to combinations thereof. The method can use a customizable traction device having a shearable fraction head and body. The shearable traction head and body can each be cut to a custom size to fit a user.

  • Patent number: 8434493
    Abstract: The adjustable mouth shield device provides an adjustably fitted mouth shield with adjustable headband for secure fit. The adjustable headband is fastened to the padded earpiece. The straight first extension from the earpiece is angled downwardly and forwardly to terminate in a swivel joint providing almost 360 degrees of swivel. The second extension is arced both downwardly and forwardly. The u-shaped mouthpiece is fitted to the adjustable spring mount for horizontal pivot of the mouthpiece. The mouthpiece may, by virtue of the swivel joint and the spring mount, be moved completely away from a user's mouth and, in turn, pivoted and swiveled to be directly in front of the user's mouth. The inward curves at the distal end of the mouthpiece aid in sliding on the disposable pads that shield a user from objects, foods and other materials.

  • Patent number: 8424524
    Abstract: A method and apparatus for providing an average signal characteristic profile derived from signals obtained from different cycles of a cyclically recurring physiological phenomenon. A signal produced from first and second cycles of the physiological phenomenon is sampled at a series of data points to obtain second physiological property values at the data points. The change in the second physiological property values for the first cycle signal between a pair of successive data points and the change in the second physiological property values for the second cycle signal between the same pair of successive data points are determined and averaged. The average change amount is applied to a value of the average signal characteristic profile at one of the pair of successive data points to produce a new second physiological property value for the average signal characteristic profile at the other of the data points of the pair.
