Claims (10)
1. A ventilation therapy device configured to deliver a breathing gas to a patient, the ventilation therapy device comprising:
a body configured to generate pressurized breathing gas by pressurizing the breathing gas, the body having a housing;
a humidification assembly for humidifying the pressurized breathing gas to form pressurized humidified breathing gas, the humidification assembly comprising a liquid chamber containing one or more liquids, the liquid chamber having a humidified gas outlet;
a main gas outlet in communication with the humidified gas outlet configured to discharge the pressurized humidified breathing gas to a breathing tube, the humidified gas outlet having a sensing orifice disposed therebetween;
a gas parameter detection assembly configured to detect a parameter of the pressurized humidified breathing gas, the gas parameter detection assembly including a sensor for detecting and a draft shield for capturing a detected gas flow and directing the detected gas flow to the detection orifice; wherein,
the flow guide waterproof cover is arranged on the detection hole and sealed with the periphery of the detection hole.
2. The ventilation therapy device of claim 1,
the main body includes a breathing gas return chamber that returns the pressurized and humidified breathing gas to the main body, both ends of the breathing gas return chamber are respectively communicated with the humidified gas outlet and the main gas outlet, and the detection hole is provided in the breathing gas return chamber.
3. The ventilation therapy device of claim 2, wherein the flow-through waterproof cover comprises:
an input port disposed on a first surface of the draft shield, the first surface facing the main gas outlet of the ventilation therapy device;
the output port is communicated with the detection hole and is arranged on a second surface of the flow-guiding waterproof cover, and the second surface is different from the first surface; and
a channel disposed within the draft shield, the channel configured to communicate an input port and an output port.
4. The ventilation therapy device of claim 3,
the detection hole is arranged on the bottom surface of the breathing gas return cavity, the second surface is in fit sealing with the breathing gas return cavity, and the output port is in direct sealing communication with the detection hole; the input port is higher than the bottom surface of the breathing gas return chamber.
5. The ventilation therapy device of claim 3,
the channel is a curved channel.
6. The ventilation therapy device of claim 5,
