Abstract:
A breath monitoring device including a flow sensor that may measure a respiration rate of a patient and to identify apnea events in the patient's breathing; a CO 2 sensor that may operate at low power and to measure a CO 2 concentration in the patient's breath; and a processor that may integrate the measurements obtained from the flow sensor and the CO 2 sensor and to determine the respiratory status of the patient based on the integration.
Abstract:
A nasal mask having a seal housing and a flexible nasal seal connected or connectable to the seal housing to define a mask cavity. The nasal seal extends between a face- contacting side and an outer side. The nasal seal has a contacting surface having an edge that defines a nose-receiving opening into the mask cavity and which is configured to seal about the user's nose. The nasal seal also has an under-nose support fixedly connected into the seal and which is configured to extend within the mask cavity and having a contact surface that is oriented to contact at least a portion of the under-nose surface of the user.
Abstract:
A nasal cannula has a single-piece generally U-shaped body defining a pair of nasal prongs extending from a base of the body, the body being deformable in such a way that the nasal prongs clamp against a columella of the patient's nose. Each of the nasal prongs include an aperture and a first gas channel in fluid communication with at least one of the apertures. The first gas channel extends from the body though a bent section located about the patient's mouth and over the cheek of the patient when the nasal cannula is worn.
Abstract:
A breathing mask which is convenient for enteral nutrition using a nasogastric feeding tube when the mask is in use may be provided. The breathing mask may include at least one nasogastric tube port. The port may allow a nasogastric tube to pass through the mask without substantially affecting the seal or pressure of the mask while accommodating enteral feeding. In addition, the breathing mask may incarnate the human-centered design to reduce discomfort in patients and is favorable for therapy and rehabilitation.
Abstract:
A device is provided for controlling the nitric oxide levels within the lungs of a subject. The device comprises a detector for detecting the respiration cycle of the subject and a stimulator for applying an acoustic or vibratory stimulus to the subject. The stimulator is controlled in dependence on the detected respiration cycle. In particular, acoustic stimulation may be provided at the onset of inspiration. In this way, the nitric oxide flow can be controlled in a way to ensure that the paranasal nitric oxide is nearly fully inspired. This provides a higher nitric oxide concentration in the lung/alveoli.
Abstract:
A cushion assembly for a patient interface includes an elastomeric seal-forming portion that includes a dome-shaped superior region (3180A); a saddle-shaped inferior region (3180G); a first support region (3180E) having a consistent wall thickness, preferably 2 mm, that is greater than the wall thickness of the dome-shaped superior and the saddle-shaped inferior regions, preferably 0.3 mm; a second support region (3180D) having a varied wall thickness and is bounded by the first support region (3180E) on a proximal side and having a distal side opposite the proximal side. In claim 1, the wall thickness in the second support region (3180D) increases from the distal side to the proximal side, preferably 2 to 1.3 mm. Preferably, wall thickness of a third support region (3180F) is 1.3 mm, a compliant region (3180C) is 0.85 mm and a flap (3180H) is 0.5 mm. Preferably flap (3180H) moves independently of a loop connection (3110).
Abstract:
A headgear assembly for retaining a respiratory mask on a user's face is provided. The headgear assembly comprising an adjustment mechanism or arrangement that includes a pair of rails configured to allow a first and second strap to be slideably moved relative to each other to adjust the size of the headgear assembly.
Abstract:
Methods and apparatus provide automated circuit disconnection monitoring such as for a respiratory apparatus or system. Disconnection of a patient circuit, including a patient interface and air delivery circuit, may be detected and a message or alarm activated. In some versions, detecting occurrences of circuit disconnection event(s), such as by a processor, may be based on an instantaneous disconnection parameter as a function of a disconnection setting. The disconnection setting may be determined based on patient circuit type. The instantaneous disconnection parameter may be determined from detected pressure and flow rate, and may be, for example, a conductance value or an impedance value. Disconnection events may be qualified by one or more detected respiratory indicators. In some cases, instantaneous impedance or conductance may be used to assess re-connection of a patient circuit, detection of flow starvation, determine breath shape for triggering and cycling and to detect patient or circuit obstructions.
Abstract:
A device especially for avoiding absorption and production of nasal and sinus nitric oxide in the paranasal sinuses and to suppress disorders of the neuropsychiatric and some respiratory tracillnessest, comprising housing,energy supply unit,blowing fan,in communication with normal outlet and heat producing part. It is designed as a unit which produces removal and blowing of air or a few minutes at a time and additionally blowing hot air to perioral nasal or facial skin to keep awake or actually increase nasal and sinus mucosal sympathetic tone. This device especially can be used to reduce sleepiness during important events or occasions such as during driving, studying, listing to lectures,security services and machinery works.The proposed device is preferably suitable for the treatment and a clue to diagnosis of diseases of the neuropsychiatric illness on the basis of sinus hypoxic nitric oxide phenomena, such as, migraine, vertigo,narcolepsy, sleepiness,psychological stress(e.g..laziness, lethargy, fear, )and impulseor impulsive moods(e.g.anger, sorrow,,which does harm to self or others ),and improving respiratory and neurological health. In addition, the device can be used to decrease other illnesses comorbidity with migraine or SHNOP such as endocrine disorders,cardiac diseases skin diseases sinus etc.
Abstract:
Methods for performing oral care on a person receiving positive air pressure ventilation include providing a positive air pressure mask with a self-sealing valve, inserting an oral care appliance through the self-sealing valve to perform oral care and maintaining positive pressure performing an oral care procedure. The invention also relates to a positive pressure mask that includes a mask body defining a cavity and having a peripheral seal configured to engage a wearer's face under pressure. A port in the body is configured to receive pressurized air. A self-sealing access valve is configured to provide direct external access to the cavity, wherein the access valve has an open diameter of at least 10 mm and self-seals under a pressure of 5-25 cm H 2 0 (500-2500 Pa).
