Provided is a wearable, self-contained drug infusion or medical device capable of communicating with a host controller or other external devices via a personal area network (PAN). The medical device utilizes a PAN transceiver for communication with other devices in contact with a user's body, such as a physiological sensor or host controller, by propagating a current across the user's body via capacitive coupling. The wearable nature of the medical device and the low power requirements of the PAN communication system enable the medical device to utilize alternative energy harvesting techniques for powering the device. The medical device preferably utilizes thermal, kinetic and other energy harvesting techniques for capturing energy from the user and the environment during normal use of the medical device. A system power distribution unit is provided for managing the harvested energy and selectively supplying power to the medical device during system operation.

An apparatus for inhibiting melatonin synthesis in a horse comprises a blinker having an internal surface of which at least a part is diffusing. A source of light is positioned for direction into the horse's eye by the diffusing-surface. The light source and diffusing surface are configured such that the light directed into the horse's eye is blue.

A medication delivery system having a holding chamber capable of delivering dosages of medicament from a metered dose inhaler. The holding chamber includes an actuator detector, flow detector and display. In another embodiment, a medication delivery system includes a holding chamber having an input and an output end, a metered dose inhaler operably coupled to the input end of the holding chamber, and a metered dose inhaler identifier associated with the holding chamber and operable to identify the metered dose inhaler coupled to the holding chamber.

A PAP system includes a PAP device to generate a supply of pressurized air, a patient interface adapted to form a seal with the patient's face, air delivery tubing to interconnect the patient interface and the PAP device, and a cover that substantially encloses at least a portion of the PAP device and a portion of the air delivery tubing. The cover allows the PAP device to be carried by and/or supported on the patient's head.

In some examples, an implantable infusion device (100) using a piezoelectric and/or electrostrictive mechanical pumping catheter (10) includes a reservoir (109) configured to retain for a fluid to be dispensed within a patient, at least one piezoelectric and/or electrostrictive mechanical pumping catheter for dispensing the fluid contained within the reservoir, a transceiver, and a processor (103) to regulate control the operation of the piezoelectric and/or electrostrictive mechanical pumping catheter.

Provided is an intubation assembly enabling whether or not a patient is breathing to be determined. The intubation assembly includes an intubation tube and a detector connected to a portion of the intubation tube in an air communicating manner. The detector includes a housing having a transparent window and a movable body disposed within the housing to be movable in response to a flow of air caused by breathing of a patient. The detector attached to a related-art intubation tube enables a doctor or an emergency medical technician to visually or sonically determine whether or not a patient is breathing.

A medical device includes a user interface component and an energy harvesting system coupled to the user interface component. The energy harvesting system energy includes a harvesting component, a power storage device connected to the energy harvesting component and an output is coupled to the user interface and operably connected to the power storage device. A method of using the medical device is also provided.

A ventilator includes an enclosure, a tubing configured to receive an input gas, and a flow outlet airline in fluid communication with the tubing. The flow outlet airline includes an airline outlet. The ventilator further includes a breath detection airline including an airline inlet. The airline inlet is separated from the airline outlet of the flow outline airline. The ventilator further includes a pressure sensor in direct fluid communication with the breath detection airline. The ventilator includes a controller in electronic communication with the pressure sensor and an internal oxygen concentrator in fluid communication with the tubing. The internal oxygen concentrator is entirely disposed inside the enclosure.

A ventilator includes a bidirectional breath detection airline and a flow outlet airline. The flow outlet airline includes an airline outlet. The ventilator further includes a breath detection airline including airline inlet. The airline inlet is separated from the airline outlet of the flow outline airline. The breath detection airline is configured to receive breathing gas from the user during exhalation by the user via the airline inlet. The ventilator further includes a pressure sensor in direct fluid communication with the breath detection airline. The pressure sensor is configured to measure breathing pressure from the user and generate sensor data indicative of breathing by the user. The ventilator further includes a controller in electronic communication with the pressure sensor. The controller is programmed to detect the breathing by the user based on the sensor data received from the pressure sensor.
