Abstract: The invention relates to a beverage receptacle (10) comprising a receptacle body (12) and an active heating system (20). The receptacle body provides a chamber (16) for receiving a beverage and a cavity (18) which contains at least part of the active heating system. The active heating system comprises a heater (26) arranged to output heat to contents of the chamber, a rechargeable electrical energy store (32), a temperature sensor (44), control electronics (on a PCB 30) which control supply of electrical power from the electrical energy store to the heater in response to an output of the temperature sensor in order to regulate temperature of the contents of the chamber, and a wireless power receiver (38) for receiving electrical energy from a charging station to charge the electrical energy store without making an electrically conductive connection to the charging station.

Abstract: A tracheostomy device has a short tube terminating adjacent the internal end of an opening into the trachea. A flange secures the external end of the tube and a retainer secures the internal end of the tube against the surface of the trachea. The device also includes a seal, which engages the surface of the trachea above the opening, and a suction passage extending externally by which secretions can be removed.

Abstract: An instrument for providing ventilation access to the trachea has a hollow needle with a sharp tip, a tube extending within the needle and a spring urging the tube to project a short distance from the patient end of the needle. The rear end of the tube carries two colored flags one of which is visible at a time in a transparent window towards the machine end of the needle. When the patient end of the instrument is pushed through neck tissue overlying the trachea the inner tube is pushed rearwardly so that a flag of one color is visible. When the patient end of the instrument enters the trachea the spring can push the inner tube forwardly so that the other flag is visible. In one embodiment the instrument carries a dilator and tracheostomy tube that can be slid off the needle after penetration. In another embodiment, ventilation equipment is connected to the rear of the inner tube and the patient is ventilated through the instrument itself.

Abstract: A tracheostomy device has a short tube (10, 10?, 10?) terminating adjacent the internal end of an opening (4) into the trachea (2). A flange (13) secures the external end of the tube and a retainer (14, 45, 59, 61) secures the internal end of the tube against the surface of the trachea (2). The device also includes a seal (3, 60), which engages the surface of the trachea (2) above the opening, and a suction passage (34) extending externally by which secretions can be removed.
