Founded in Australia, ResMed is a global manufacturer of products for the treatment of sleep disorders, particularly obstructive sleep apnea . ResMed employs more than 4300 employees worldwide, it operates in 100 countries and has manufacturing in Australia, France, Singapore and the United States. In the fiscal year 2013/2014 it achieved revenues of US$ 1.5 billion.ResMed considers the OSA market as underpenetrated and joined a partnership with LifeScan, a Johnson & Johnson company in 2009 to increase awareness of OSA amongst type 2 diabetes patients. ResMed also raises awareness of the serious comorbidities linked to untreated sleep disorders which includes cardiovascular disease, stroke and obesity. Wikipedia.

A mask for delivery of respiratory therapy to a patient may include one or more of the following improvements: rigidizer provided to headgear strap, locking clip/clip receptacle headgear connection, keyed headgear buckles, lotion dispenser on frame, rotatable prongs to adjust orientation, alignment indicators provided to prong, cushion and/or frame, chin flap with bellows arrangement, vent holes positioned away from gas entry port, and vent holes to direct washout gas at an angle.

A ventilator system includes a mask to be placed over a wearers face. The mask has a shell. The ventilator shell further includes a cushion provided to the shell to sealingly connect the mask to the wearers face and thereby form a chamber between the shell and the wearers face. The ventilator system also includes an inlet port in the shell and an air flow generator. The inlet port is configured to receive a flow of breathable gas. The air flow generator is mounted on the mask and is capable of creating a pressure of about 2-40 cm H_(2)O in the chamber.


A PAP system for delivering breathable gas to a patient includes a flow generator to generate a supply of breathable gas to be delivered to the patient; a humidifier including a heating plate to vaporize water and deliver water vapor to humidify the supply of breathable gas; a heated tube configured to heat and deliver the humidified supply of breathable gas to the patient; a power supply configured to supply power to the heating plate and the heated tube; and a controller configured to control the power supply to prevent overheating of the heating plate and the heated tube.


Methods and apparatus are disclosed for determining the occurrence of a closed or open apnea. Respiratory air flow from a patient is measured to give an air flow signal. The determination of an apnea is performed by applying an oscillatory pressure waveform of known frequency to a patients airway, calculating a complex quantity representing a patient admittance (12) and comparing its value with ranges (14,16) indicative of open or closed apneas. The method distinguishes open from closed apneas even when the model used to calculate admittance is not based on details of the respiratory apparatus. In addition the patient admittance may be compared with admittance during normal breathing to avoid having to characterize the airway.


Methods and apparatus for treating a respiratory disorder, in one aspect, include an apparatus that delivers backup breaths at a sustained timed backup rate that is a function of the patients spontaneous respiratory rate. Other aspects include apparatus that delivers backup breaths at a rate that gradually increases from a spontaneous backup rate to a sustained timed backup rate or, alternatively, apparatus that oscillates a treatment pressure in antiphase with the patients spontaneous respiratory efforts when a measure indicative of ventilation is greater than a threshold. Other aspects include apparatus configured to treat Cheyne-Stokes respiration by computing the treatment pressure so as to bring a measure indicative of ventilation of the patient towards a target ventilation that is dependent on the measure indicative of ventilation or, alternatively, by periodically elevating the treatment pressure to a high level for a short time, the high level being high enough and the short time being long enough to induce a central apnea in a patient. Depending on functionality, the foregoing apparatus may comprise an adaptive servo-ventilator or CPAP therapy device.

A vent assembly for use with a respiratory mask of the type used in CPAP treatment includes a porous disk portion that is attached to a biasing member such that the disk portion is maintained in a substantially sealed position against a main vent to minimize airflow through at least one side vent of the vent assembly. Debris build-up on the disk portion can cause the biasing member to deflect to provide an additional path for airflow through the at least one side vent. In another embodiment, the vent assembly can also include an anti-asphyxia feature to provide an airflow path from the environment to the user. An oxygen diverter valve may be disposed between the breathing apparatus flow generator and an oxygen injection port.


A headgear for a respiratory mask of a ventilator or CPAP device is provided. The headgear includes a strap portion formed of a substantially inextensible material. The strap portion has formed on one end thereof a connecting structure configured to connect to a mask of the ventilator or CPAP device. One advantage is that the mask will not or at least will be less inclined to lift off the face as mask pressure is increased.

An air delivery conduit for conveying breathable gas from a positive airway pressure device to a patient interface includes a tubular wall structure constructed from a textile material. A reinforcing structure may be provided to the wall structure that is structured to prevent kinking or collapsing of the wall structure. The wall structure may include a warp having a plurality of lengthwise textile warp threads arranged in a circle and a weft having a textile weft thread that is woven through the warp threads.

A humidifier for humidification of air to be delivered to a patients airways may include a humidification chamber, a reservoir and a water delivery mechanism. The humidification chamber may include a water retention feature such as a wick that encloses part of the flow path, a heating element for heating the humidification chamber, and an air flow baffle configured to promote humidification. The humidifier may be further configured to execute one or more algorithms, for example to determine a condition of the wick or to detect condensation in the flow path. In some forms, the humidifier may also comprise algorithms for controlling one or more components of the humidifier such as to control the build up of foreign matter on the wick.


Patent
ResMed | Date: 2017-04-05

A method and apparatus monitors chronic disease state of a patient. The method may include extracting, in a processor, for each of a plurality of monitoring sessions, a respiratory feature from a respiratory signal indicative of the patients respiration during the monitoring session, the respiratory signal derived from at least one sensor; and computing, in a processor, a stability measure of the patient for a monitoring session, the stability measure representing an indication of a change point having occurred at the monitoring session in a statistical distribution of the respiratory feature.
