An oxygen concentrator 100 apparatus and a method thereof implement operations control to efficiently release oxygen enriched gas to reduce potential waste. The control methodology may include generating a profile such as a minimum inhalation flow profile of the user. The profile may be based on a size parameter of the user. The method may determine one or more control parameters characterizing a bolus of oxygen enriched gas based on the generated flow profile. The control methodology may then generate a bolus release control signal, such as for a supply valve, according to the determined one or more control parameters. The oxygen concentrator may then, with the control signal, release and deliver a bolus of oxygen enriched gas for a user such as for reducing waste.

The present invention relates to an automated stimulation device for inducing a tactile inter-stimulus onset asynchrony (ISOA) effect in a subject suffering from apnea, bradycardia and/or hypoxia, the device comprising at least two actuators configured for contacting a body portion of the subject, and interspaced for producing an apparent tactile movement in the subject upon sequential induction of actuation, wherein the duration of the actuations and the overlap in actuation time between the at least two actuators is controlled to attain an inter stimulus onset asynchrony (ISOA).

An apparatus for acoustically detecting the location of a distal end of a tube relative to a body conduit into which the tube is being inserted is provided. The apparatus including a speaker positioned to generate a sound pulse in the tube and a sensor for detecting a sound pulse in the tube at a distal position relative to the speaker, and for generating a signal corresponding to the detected sound pulse.

A tool for manipulating a catheter interface protection device includes a base, a first arm extending from the base, and a second arm extending from the base. The first arm includes an outwardly projecting first hook configured to engage a first vent of a catheter interface protection device. The second arm includes an outwardly projecting second hook configured to engage a second vent of the catheter interface protection device. A method of manipulating a catheter interface protection device includes positioning the base around the catheter interface protection device so that the first arm is on a first side of a slot of the catheter interface protection device and the second arm on a second side of the slot of the catheter interface protection device opposite the first side, and bending the catheter interface protection device from the slot towards and around the first hook to create an opening.

The present invention relates to a device (100) and a system for positive pressure ventilation (PPV) and continuous positive airway pressure (CPAP) treatment comprising a fresh gas flow inlet (2), arranged to receive a fresh gas flow from a fresh gas flow tube (22) connectable thereto; a patient interface end (3), arranged to be connected with a patient interface; an outlet (4) having an open end (5); a variable flow CPAP generator (6) comprising first, second and third connection portions (10, 11, 12), wherein the first connection portion is connected with the fresh gas flow inlet, the second connection portion is connected with the patient interface end, and the third connection portion is connected with the outlet, wherein the generated CPAP level is adjusted by varying the fresh gas flow to the variable flow CPAP generator. The device further comprises an internal leakage channel (9) arranged to extend between the fresh gas flow inlet and at least one of the patient interface end and the outlet, such to create an internal fresh gas leakage flow there between, bypassing the first connection portion of the variable flow CPAP generator, which is added to the fresh gas flow provided by the variable flow CPAP generator in the PPV mode. A simplified device and system is provided, respectively, which is easy to use and allows for a rapid switch between PPV and CPAP treatment without change of equipment.

Systems and methods are disclosed for delivering medication to a patient. One such system has an aerosol generator for aerosolizing medication. The generator is located outside the airway of a patient. A chamber is provided for receiving aerosolized medication from the generator. The system has a carrier gas supply tube for delivering carrier gas to the chamber, and an aerosol delivery tube for receiving the aerosolized medication and the carrier gas from the chamber. The aerosol delivery tube delivers the aerosolized medication to the patient. A distal end of the aerosol delivery tube is positioned inside the airway of the patient in order to discharge the aerosolized medication within the patient's airway.

A method for providing vestibular stimulation includes: providing an infant in a vestibular stimulation device; associating sensors to the infant; moving the vestibular stimulation device to provide vestibular stimulation treatment; and obtaining sensor data during the treatment. The vestibular stimulation device includes a holder member; a platform; a mechanical system coupling the holder member to the platform; sensors configured to detect one or more parameters of the infant; and a computing system having a user input and/or output interface operably coupled to the mechanical system and the sensors to provide mechanical data to the mechanical system in order to control movement of the holder member relative to the platform and to collect the one or more parameters of the living subject from the sensors.

An apparatus and process (100) for processing data (101, 102, 103) obtained by an imaging technique enables an improvement of a determination of quality and quantity of ventilation of the lungs. By including a correction data set KDS determined during one or more inhalation phases, it is determined which effects result from adjustments of pressure levels (PEEP.sub.A, PEEP.sub.B) (81, 82) during ventilation. The result of the determination is provided as an output signal (900).

A cannula system for cannulating a blood vessel comprising a collet comprising at least a first collet wing and a second collet wing and defining a collet lumen, where each of the first collet wing and the second collet wing define a distal end and a proximal end; a cannula positioned within the collet lumen; a latch defined on the distal end of the first collet wing; and a coupler defined on the distal end of the second collet wing and configured to couple to the latch of the first collet wing, thereby securing the first collet wing to the second collet wing.

The present invention is a respiratory monitoring device which uses 2+ sensors to map respiratory motion in patients to interpret into a respiratory effort and severity score. The core components of the invention are contact-based sensors that measure relative motion of the chest, abdomen, and/or other key anatomical features, a processing unit which takes in the data from all sensors, an algorithm that analyzes and compares the data from each sensor to understand relative motion and interpret it into clinically-relevant information, and a display screen that shares this information with clinicians. The sensors are connected to each other and the information processing unit which shares data with the screen for display of a respiratory severity score based on analysis of Thoraco-Abdominal Asynchrony (TAA) or similar indicators of respiratory effort as measured by the sensor network and analyzed by the algorithm.
