  • Publication number: 20210220600
    Abstract: There is provided a humidifier for a respiratory therapy system that includes a humidification chamber having an inner wall spaced from an outer wall to form a wall cavity between the inner and outer walls. A gas flow path is located within the wall cavity. Gas, such as air, flows along the gas flow path from an inlet to the humidification chamber to an outlet of the humidification chamber. Optionally, the gas flow path may follow a helical route through the wall cavity.

  • Publication number: 20210069454
    Abstract: A gas humidification system can have a conduit defining a gas passageway. A mass of a first absorbent material can be located in the conduit. A mass of a second absorbent material can cover at least a part of the surface of the conduit. An orifice can be located on the conduit to allow communication between the first and second absorbent materials. A heating element can be placed within, on, around, or near the first absorbent material. The heating element can heat up moisture in or on the first absorbent material such that the moisture is encouraged to join gases passing through the gas humidification system.

  • Patent number: 10213095
    Abstract: The invention discloses a percutaneous puncture and dilation visible irrigation-suction system and a method of using the same. The system comprises a main tube, which is contiguous with the sheath tube and has an end for an endoscope insertion. The sheath tube comprises an inner sheath and an outer sheath joined together in a sleeve type. There is a space between inner and outer sheath. The inner sheath is connected to main tube, together building a channel via which the endoscope is inserted and withdrawn. The sheath tube is connected to main tube after completing puncture and dilation, then endoscope system is introduced for observation and operation. The present invention provides a percutaneous puncture and dilation visible irrigation-suction system and a method of using the same, with a continuous controllable visible negative pressure aspirator, achieving high irrigation and powerful suction efficiency, as well as clear endoscopic view.

  • Publication number: 20140060533
    Abstract: A respiratory humidification system that controls the humidity of the outlet gases using an enthalpy based calculation is disclosed herein. The respiratory humidification system includes a controller that can receive data from one or more of an enthalpy sensor, a flow sensor and a temperature sensor. The controller can also receive information relating to the outlet gas enthalpy, which can be calculated from the desired output temperature and humidity. A level of power to be provided to the heating system to achieve the desired output temperature and humidity can be calculated using data from the enthalpy sensor, flow sensor, and temperature sensor, as well as the calculated outlet gas enthalpy.
