摘要:
A portable oxygen concentrator system weighing 4-20 pounds that is adapted to be readily transported by a user and deliver oxygen to the user includes a rechargeable energy source; a concentrator powered by said energy source and adapted to convert ambient air into concentrated oxygen gas for the user; an inspiration sensor that senses respiratory activity of the user, and produces a signal in response thereto; and a control unit that receives the signal in response to sensed respiratory activity, determines a breath rate based in part on the received signal in response to sensed respiratory activity and controls the portable oxygen concentrator system to deliver oxygen flow sufficient to meet oxygen demand of the user based at least in part on the determined breath rate.

Systems and methods for monitoring, diagnosing, and/or treating a patient are provided. One or more individual medical procedures may be utilized to monitor, diagnose and/or treat the patient. Two or more of the individual medical procedures or may be used in combination to provide more comprehensive patient monitoring, diagnosis and/or therapy. One or more functions of two or more individual medical procedures may be used in combination to enhance patient monitoring, diagnosis and/or therapy. The medical procedures may be coordinated. Coordinated medical procedures may involve cooperative operation of two or more of the individual processes. Coordinated medical procedures may also involve cooperative operation of one or more functions of two or more of the individual processes.
摘要:
An approach to providing disordered breathing therapy includes sensing conditions affecting the patient and adapting a therapy to mitigate the disordered breathing based on the sensed conditions. The therapy may be adapted to enhance therapy effectiveness, to provide therapy that reduces an impact of the therapy on the patient, or to achieve other therapeutic goals. Cardiac electrical therapy to mitigate the disordered breathing may include various cardiac pacing regimens and/or delivery of non-excitatory electrical stimulation to the heart.
摘要:
Respiratory support and/or controlled mechanical ventilation of a patient are provided. A ventilation apparatus may include a ventilator, a transtracheal prosthesis, and a respiratory relief device. The transtracheal prostheses and ventilation catheter may be arranged such that the patient can breathe freely through the upper airway and/or the tracheal prostheses. Respiratory sensors may measure a breathing rate, lung pressure, airway pressure, or a combination thereof. Pulses of gas may be provided to the patient through the ventilation catheter during inspiration. The pulses may have a first volume while the patient breathes normal and a second volume when the sensors detect a cessation of breathing or reduction in breathing volume. The second volume may be provided at 1 - 5 times the normal breathing rate, with a volume 25 - 500% times the first volume, or both.
摘要:
A portable oxygen concentrator system (100) adapted to be readily transported by a user includes a rechargeable energy source (104) and a concentrator (114) powered by the energy source (104). The concentrator (114) converts ambient air into concentrated oxygen gas for the user and includes a plurality of adsorption beds (300) and a rotary valve assembly (310). The rotary valve assembly (310) is relatively rotatable with respect to the plurality of adsorption beds (300) to provide valving action for selectively transferring fluids through the plurality of absorption beds (300) for converting ambient air into concentrated oxygen gas for the user. The ratio of adiabatic power to oxygen flow for the concentrator (114) is in the range of 6.2 W/LPM to 23.0 W/LPM.
摘要:
Resuscitation device for humans comprising: - a sensor for detecting a number of parameter values in a human being; - at least one memory for storing a predetermined function and a number of detected parameter values; - at least one processing unit connected with the sensor and the memory for processing the number of detected parameter values in the predetermined function to determine whether the human being is in a state of developing apnoea; - a response device connected with the processing unit for providing a response as a function of the number of processed parameter values by the at least one processing unit when the at least one processing unit has determined that the human being is in the state of developing apnoea. The resuscitation device is an apparatus comprising both the sensor, the memory, the at least one processing unit and the response device, the apparatus being arranged to be attached under a human's nose, the sensor being arranged to sense breathing activity, and the response device comprising a stimulation device designed to provoke an induced aspiration reflex by a resuscitating stimulation of the respiratory area of the human brain stem by providing a stimulus to a nasal filter of the human being.
摘要:
An interactive system (2) for providing sensory stimulation to a subject (30), the interactive system comprising a main (4) and satellite housings (14, 16), the housing being portable across surfaces, whilst still able to be secured to fixtures or other fittings while in use; a plurality of sensory stimulation means disposed within the main or satellite housings and adapted for providing sensory stimulation to the environment surrounding the housing, the sensory stimulation means providing stimulation for one or more smell, sound, wherein the system comprises interactive processor, remote control devices (34), switches and/or physiological measurement equipment (32). The sensory stimulation means may be electrical or non-electrical. The interactive system preferably comprises a power storage and delivery device, such as a battery. The housing is preferably arranged without sharp edges or protrusions, in order to avoid harm to users and is capable of being cleaned in line with current hospital clinical infection control procedures.
摘要:
The support and control appts. includes a frame (16), and an upwardly facing patient support surface (40) with a perimeter carried by the frame. An air generator is mounted on the frame and provides two curtains of air. Each air curtain originates adjacent to the perimeter and converges at a point above the patient support surface. The curtains combine with the support surface to define a patient space. A third curtain of air is provided originating adjacent to the perimeter of the support surface and directed into the patient space. A fourth air curtain opposes the third and is directed into the patient's space.
