Abstract: A noise-reducing respiratory device configured to improve or treat respiratory system-related disorders such as sleep apnea. The device includes a noise-reducing gas passage located inside a casing of the device, and is connected to the casing. The casing of the respiratory device also has at least one air intake and at least one air outlet. The air intake is configured to receive breathable gas into the chambers of the noise-reducing gas passage. The air outlet is configured on one side to communicate with an outlet of the blower, and on the other side, it connects to a breathing hose. Additionally, electronic components and a soundproofing material are provided between the noise-reducing gas passage and the casing of the device. Furthermore, there is no foam present where the internal gas flows through the respiratory device.

Abstract: A noise-reducing gas passage device with a resonant chamber, including a casing with an air intake and air outlet, which forms the resonant chamber and other chambers other than the resonant chamber. The other chambers may consist of a single chamber or multiple chambers. The other chambers including multiple chambers have a first chamber and a second chamber. The resonant chamber serves as the primary noise-reducing structure within the gas passage device, configured to be a cavity formed by the interior space of the casing. The noise-reducing structure also includes a neck, configured to communicate the resonant chamber with the other chambers, facilitating the transmission of sound waves into the resonant chamber for energy conversion. By controlling the position of the resonant chamber and the parameters of both the resonant chamber and the neck, maximal noise reduction in the noise-reducing gas passage is achieved.

Abstract: A gas passage for use in a PAP device configured to provide pressurized gas to a patient, including a passage casing with an air intake and an air outlet. The casing is configured to encompass and accommodate internal components and forms a chamber inside, where the chamber is configured to facilitate the flow and accumulation of gas. A blower is provided within the chamber to pressurize and output the gas. The internal components of the noise-reducing gas passage include noise reduction components configured to attenuate the noise of the gas entering the noise-reducing gas passage. These noise reduction components include a ventilation component, an intake pipe, and a flexible component at the air intake. Additionally, this disclosure specifies scientific and precise data requirements for the internal structure and positioning of the blower and noise-reducing components within the noise-reducing gas passage to achieve effective and excellent noise reduction.

Abstract: A blower with a gas pressurization system. The blower includes a blower housing with a gas inlet and a gas outlet, a brushless direct current motor including a rotor assembly, a stator assembly, at least one permanent magnet, and bearings, and an impeller positioned between the stator assembly and the gas inlet. The housing and the outer surface of the motor are configured to collectively form a gas passage that provides a helical gas flow. During operation, gas enters the gas passage of the blower through the gas inlet. The stator assembly drives the rotation of the rotor assembly, causing the rotor assembly to drive the impeller at high speed, thereby pressurizing the gas to a range of 2 cmH2O to 40 cmH2O. The pressurized gas then flows through the gas passage of the blower and is expelled through the gas outlet.

In this disclosure, the ozone disinfection device includes the ozone recovery module that includes a filter. A total surface area, a specific surface area, and a porosity of at least one filter material in the filter are defined to increase the filter's recovery efficiency. Furthermore, the filter may also be detachable, in cooperation with a housing structure, enabling a user to inspect or replace the filter independently and thus prolonging the overall service life of the ozone disinfection device. In some embodiments, the ozone disinfection device also includes at least one sensor and an alarm system to achieve intelligent control and prevent potential hazards.

Abstract: A ventilation component for use in an anti-snoring device. The ventilation component is provided within a noise-reducing air passage of a machine for the treatment of respiratory-related disorders such as a PAP machine. The internal structure of the ventilation component is formed by baffles arranged at certain intervals. When the ventilation component operates, the gas that enters its interior flows through the gaps between the baffles, where the gas is divided and streamlined to achieve noise reduction. The ventilation component can adopt various structural forms and combinations to reduce noise. It also has the flexibility to alter its shape and structure based on the form of the noise-reducing air passage.

Abstract: A respiratory obstruction removal device, which includes a face mask and a negative pressure generating device. The negative pressure generating device includes a grip section, an extendable tubular body, and an annular interface, connected in sequence. The extendable tubular body has a variable volume cavity. The face mask includes an upper part that fits with the annular interface, a lower part that corresponds to a face of a patient, and a connecting body that links the upper and lower parts. The respiratory obstruction removal device also includes a first one-way valve located on the annular interface and a second one-way valve for unidirectional expulsion of gas to the outside. The grip portion and the extendable tubular body are detachably connected. This design is efficient and easy to carry and transport, suitable for emergency use in different scenarios.

Abstract: A noise-reducing air passage device and its components for use in ventilator systems, including a housing with at least one inlet, at least one outlet, an inner wall, and an outer wall.
