Means For Heating Respiratory Gas Or Respiration Device Patents (Class 128/204.17)
  • Patent number: 10449323
    Abstract: In some embodiments, a humidification system includes a heater base having a heater plate, a humidification chamber, and circuit. The circuit can include various conduits, including an inspiratory conduit, expiratory conduit, Y-piece, patient conduit, and/or dry conduit. In use, the chamber contains a quantity of liquid. The heater base heats the heater plate, which in turn heats the liquid to a temperature that causes at least some of the liquid to become vapor, thereby humidifying the gases within the chamber. The gas is delivered to the patient via the inspiratory conduit. Various features can help control the system and ensure the patient receives gases having the desired conditions. These features can be used individually or in various combinations and subcombinations both in existing humidification systems and improved systems for respiratory humidification, laparoscopy, and other purposes.

  • Patent number: 10426912
    Abstract: Some embodiments provide for an inspiratory limb for a breathing circuit that includes a first segment that comprises a first heater wire circuit and a second segment that comprises a second heater wire circuit. The inspiratory limb can include an intermediate connector that includes a connection circuit that electrically couples the first heater wire circuit to the second heater wire circuit. The inspiratory limb can be configured to operate in two modes wherein, in a first mode, electrical power passes through the first electrical connection to provide power to the first heater wire circuit without providing power to the second heater wire circuit, and in a second mode, electrical power pass through the first electrical connection to provide power to both the first heater wire circuit and the second heater wire circuit.

  • Patent number: 10398860
    Abstract: Breathing assistance apparatus includes a gases supply unit adapted to, in use, deliver a stream of pressurised gases from an outlet. The gases supply unit is adapted to vary the pressure of the stream of pressurised gases. A supply path includes a flexible self-supporting gases transportation pathway having a first end connected to the outlet so that the gases transportation pathway receives the stream of gases and conveys the gases to a patient. A patient interface is connected to the second end of the gases transportation pathway receives a stream of gases. At least one sensor measures at least one information parameter of the supply path. A control system associated with the gases supply unit receives the information parameter. The control system contains reference data, and compares the received data to reference data, and determines a supply path based on the comparison.

  • Patent number: 10278429
    Abstract: The present invention relates to an temperature control system of an e-cigarette, which includes a power supply, a liquid guiding member, and a heating element, and further includes an operating voltage input unit separately connected to the power supply and the heating element, a temperature detection unit including a voltage detection module and a temperature processing module that are connected to each other, and an operating voltage adjusting unit separately connected to the temperature processing module and the heating element. According to the present invention, a temperature of the heating element is controlled by using the temperature control system. This avoids the following problems: When the e-cigarette operates, because the temperature of the heating element increases with a longer operating time, the liquid guiding member is burnt or e-liquid molecules are cracked to produce a burnt taste, thereby affecting human health as well as smoke taste and user experience.

  • Patent number: 8757150
    Abstract: Condensation management techniques for a gas flow delivery system. The techniques include providing a radiant barrier associated with patient circuit and/or a patient interface, providing a water trap and/or an absorbent insert in the patient interface device, or a combination of these techniques. The radiant barrier prevents condensation from forming in the patient circuit and/or the patient interface. The water trap and absorbent insert in the patient interface control condensation that reaches or forms in the interior of the patient interface to prevent it from interfering the user of the gas delivery system.
