Abstract

The present invention relates to humidifier reservoirs. The present invention provides a reservoir configured to hold a volume of liquid for use in a device for humidifying a pressurized air stream, the reservoir comprising a base portion and a lid portion. The reservoir may be configured to utilize a pressurized air flow to improve its thermal contact level to the heating plate. The reservoir may be configured to improve thermal contact between the reservoir and the heating plate by pre-compression when the reservoir is engaged with the humidifier. The reservoir may include a removable intermediate portion, which may include an inlet tube and/or an outlet tube to improve access for cleaning. The reservoir may also be configured to prevent overfilling. The overfill prevention feature in the reservoir may comprise a form of a defined flow out path and/or air lock.

  15. 15. The water reservoir of claim 8, wherein the dock is configured to include a cavity having a top portion and a bottom portion, the bottom portion having a heating plate thereon, and the cavity is configured to receive a portion of the water reservoir therein.
  16. 16. The water reservoir of claim 15, wherein the at least one handle is disposed on a portion of the water reservoir that is not received by the cavity.
  17. 17. The water reservoir of claim 8, wherein the lid includes an inlet and an outlet configured to couple with the respective outlet and inlet of the dock.
  18. 18. The water reservoir of claim 8, further comprising a latch for securing the base and the lid together, and wherein the latch is configured to limit relative movement of the lid and the base in only one direction to prevent separation of the lid and the base while allowing further compression of the resilient portion.
  19. 19. A respiratory pressure device comprising a pressure generator integrated in the respiratory pressure device for supplying an air stream at a positive pressure and means for humidifying the air stream, the means for humidifying the air stream comprising: A butt joint part comprising a heating plate, and The water reservoir of any one of claims 1 to 18.

Technical Field The present technology relates to one or more of detection, diagnosis, treatment, prevention and amelioration of respiratory-related diseases. In particular, the present technology relates to medical devices or apparatus, and their use. Background Human respiratory system The respiratory system of the body facilitates gas exchange. The nose and mouth form an entrance to the patient's airway. The airways include a series of branches that become narrower, shorter and more numerous as they go deeper into the lungs. The main function of the lungs is gas exchange, allowing oxygen to move from the air into the venous blood and carbon dioxide to move from the venous blood. The trachea is divided into right and left main bronchi, which finally further divide into terminal bronchioles. The bronchi constitute a conducting airway and do not participate in gas exchange. The branches of the airways lead further to the respiratory bronchioles and eventually to the alveoli. The alveolar region of the lung is where gas exchange occurs and is referred to as the respiratory region. See western, respiratory physiology. The range in which respiratory disorders exist. Obstructive Sleep Apnea (OSA) is a form of Sleep Disordered Breathing (SDB) that is characterized by an occlusion or blockage of the upper air passage during sleep. OSA is caused by a combination of abnormally small upper airways and the normal loss of muscle coordination in the regions of the tongue, soft palate, and posterior oropharyngeal wall during sleep. This condition causes the affected patient to stop breathing during a period of typically 30 to 120 seconds duration, sometimes 200 to 300 times per night. This often results in excessive daytime sleepiness, and this may lead to cardiovascular disease and brain damage. While the affected person may not be aware of the problem, this syndrome is a common disorder, especially in middle-aged overweight men. See U.S. Pat. No. 4,944,310 (Sullivan). Tidal breathing (CSR), in which there are alternating periods of rhythmic enhanced and weakened ventilation leading to repeated de-oxidation and re-oxidation of arterial blood vessels, is an obstacle to the respiratory controller of the patient. CSR may be detrimental due to this repeated oxygen deficiency. In some patients, CSR is associated with repeated sleep arousals that result in severe sleep disruption, increased sympathetic activity and increased afterload. See U.S. Pat. No. 6,532,959 (Berthon-Jones). Obesity Hypoventilation Syndrome (OHS) is defined as the combination of severe obesity with arousal chronic hypercapnia without other known causes of hypoventilation. Symptoms include dyspnea, morning headaches, and excessive daytime sleepiness. Chronic Obstructive Pulmonary Disease (COPD) includes any of a group of lower airway diseases that have specific common characteristics. These include increased resistance to air movement, prolonged expiratory phases of breathing, and loss of normal elasticity of the lungs. Examples of COPD are emphysema and chronic bronchitis. COPD is caused by long-term smoking (major risk factor), occupational exposure, air pollution and genetic factors. Symptoms include motor dyspnea, chronic cough, and sputum production. Neuromuscular disease (NMD) is a broad term that includes many diseases that impair muscle function either directly via intrinsic muscle pathology or indirectly via neuropathology. Some NMD patients are characterized by progressive muscle damage that results in loss of mobility, being tethered to wheelchairs, dysphagia, weakening of respiratory muscles, and ultimately dying from respiratory attenuation. Neuromuscular failure can be divided into (i) a fast progressive disorder characterized by a progressive deterioration of muscle injury and leading to death within years (e.g., amyotrophic Lateral Sclerosis (ALS) and progressive muscular dystrophy (DMD) in young age) and (ii) a variable or slow progressive disorder characterized by a progressive d
