A connector interface system includes a cap to connect to a reservoir to form a reservoir/cap unit for installation into an infusion pump device. The cap has at least one receptacle for receiving one or more detectable features comprising at least one disc-shaped member, for detection by at least one sensor element on the infusion pump device when the reservoir of the reservoir/cap unit is received in a reservoir receptacle of the infusion pump device. The at least one detectable feature has at least one detectable parameter that is associated with one or more characteristics of the cap, the reservoir, the infusion pump device, a cannula associated with the cap or a tubing connected between the cap and the cannula.

Oxygen concentrator apparatus provides variation in therapy gas during a breathing cycle such as by varying flow rate and/or oxygen purity of enriched air. The apparatus may include a compressor and a valve set that operates sieve bed(s) for the enriching air and to vent exhaust gas from the bed(s). The therapy gas may include released enriched air and exhaust gas. The apparatus has a supply valve to selectively release enriched air from an accumulator via a primary path to a delivery conduit. The apparatus may include a secondary path, such as with a valve, to release a portion of exhaust gas to the delivery conduit. A controller actuates the valve set to produce the enriched air, and the supply valve to release enriched air to the delivery conduit. The controller may actuate the secondary valve in anti-sync with the supply valve to release exhaust gas to the delivery conduit.

A ventilation system including a ventilator having a cooling fan configured reduce an internal temperature of the ventilator. The ventilator also includes a controller configured to control operation of the ventilator. A detector is configured to generate a detection signal when the ventilator is connected to a cold passover humidification (CPH) device. In response to the detection signal, the ventilator reduces or eliminates operation of the cooling fan in comparison to a default mode of operation. A method of providing increasing a temperature of a flow of air to a CPH device is also included.

Embodiments of negative pressure wound therapy systems, apparatuses, and methods for operating the systems and apparatuses are disclosed. In some embodiments, a medical device is configured to detect an identity of a patient-contacting disposable connected to the medical device. The medical device automatically modifies one or more operational parameters of the medical device based on the identity of the patient-contacting disposable connected to the medical device. The medical device can include a user interface and modify automatically available selections in the user interface based on the identity of the patient-contacting disposable connected to the medical device.

Apparatus and methods for delivering humidified breathing gas to a patient are provided. The apparatus includes a humidification system configured to deliver humidified breathing gas to a patient. The humidification system includes a vapor transfer unit and a base unit. The vapor transfer unit includes a liquid passage, a breathing gas passage, and a vapor transfer device positioned to transfer vapor to the breathing gas passage from the liquid passage. The base unit includes a base unit that releasably engages the vapor transfer unit to enable reuse of the base unit and selective disposal of the vapor transfer unit. The liquid passage is not coupled to the base unit for liquid flow therebetween when the vapor transfer unit is received by the base unit.

A heatable conduit for use in a respiratory apparatus for delivering breathable gas to a patient includes a first segment comprising one or more heater wires and a second segment comprising one or more heater wires. Each of the first and second segments comprises a spirally wound elongate body. In addition, the one or more heater wires of the first and second segments are configured to be connected in use to at least one controller such that, in a first mode, power is provided to the one or more heater wires of the first segment and no power is provided to the one or more heater wires of the second segment.

A supplemental device for attachment to an injection device, the supplemental device comprising: a housing; an electromechanical switch arrangement having an open state and a closed state, the electromechanical switch arrangement comprising a protrusion configured to contact a surface of the injection device while the supplemental device is attached to the injection device; a dose dialled detector operable to detect a dose of medicament dialled into the attached injection device; and a processor arrangement configured to: monitor the detected dose of medicament dialled into the attached injection device; detect a change in the state of the electromechanical switch arrangement; and change a display output of the supplemental device when a change in the state of the electromechanical switch arrangement is detected while a zero dose is dialled into the attached injection device.

A respiratory assistance apparatus is configured to provide a heated and humidified glow of gases and has a control system that is configured to detect a fault in the flow path. A flow path is provided for a gases stream through the apparatus from a gas inlet through a blower unit and humidification unit to a gases outlet. A flow rate sensor is provided in the flow path and is configured to sense the flow rate and generate an flow rate signal and/or a motor speed sensor is provided that is configured to sense the motor speed of the blower unit and generate an indicative motor speed signal.

A computer-controlled injector for use with a medicament cartridge and including a housing having a medicament cartridge receiving volume and a medicament cartridge insertion and removal opening communicating with the medicament cartridge receiving volume; a pivot mount element mounted onto the housing for selectably enabling access to the medicament cartridge receiving volume via the opening; a mechanical latch selectably locking the pivot mount element in a closed operative orientation; and an injection drive mechanism including a computer-controlled motor for driving a piston, forming part of the medicament cartridge, for injecting a medicament, the computer-controlled motor also being operative for operating the mechanical latch.

Automation for a system and/or method detects and/or controls treatment of inspiratory flow limitation. The system may include a flow rate sensor configured to generate a signal representing a respiratory flow rate of a patient. It may include a recording device configured to record the generated respiratory flow rate signal during a diagnosis session. It may include a computing device (7040) configured to detect a degree of inspiratory flow limitation of the patient on the recorded respiratory flow rate signal. The method may include extracting an inspiratory portion of each breath during a detection and/or monitoring session from a respiratory flow rate signal of the patient, calculating a feature vector from each inspiratory flow portion, labelling each feature vector as flow limited or not flow limited, and/or computing a metric based on the labels, the metric indicating the degree of inspiratory flow limitation of the patient during the session.
