Abstract: A portable ozone disinfection device configured for disinfecting and sterilizing respiratory-related devices or respiratory accessories. Specifically, provided is an ozone disinfection device that enhances usability and comfort. The device includes a functional component end enclosed by at least one housing and an external disinfection space. The functional component end includes components such as an ozone generation system, an ozone recovery system, and an ozone operation system, the ozone operation system having at least one switch. The housing also includes at least one interface configured to connect with a hose for the delivery of ozone gas. This interface has various forms.

Abstract: An ozone disinfection device configured to connect with a hose or respiratory-related equipment for disinfection. Specifically, an ozone disinfection device is disclosed that improves safety and reliability during use. The device includes an ozone operation system and a housing. The housing includes a plurality of housing walls and at least one receiving slot and at least one ozone outlet. Additionally, the ozone disinfection device features at least one joint component configured to seal the receiving slot. The sealing of the receiving slot can be achieved in two forms. Furthermore, the ozone operation system has at least an ozone generator, an ozone distribution pipeline, and at least one fan or pump. All three components are configured to be housed within a single chamber formed by the housing of the ozone disinfection device.

Abstract: An ozone disinfection device with an ozone recovery module, the device being further configured to connect to a hose or respiratory device to disinfect the hose or the respiratory device. 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 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 suction device includes a negative pressure generator, a connector and a mask; the negative pressure generator comprises a housing and a piston rod, wherein the housing is internally provided with a cavity, an upper end of the housing is provided with an avoidance hole communicated with the cavity, and a lower end thereof is provided with an opening communicated with the cavity; the piston rod comprises a push-pull rod and a piston sleeved on the push-pull rod, an upper end of the push-pull rod runs through the avoidance hole, and the piston is movably and hermetically connected to an inner side wall of the housing by means of a sealing ring; an upper side of the mask is provided with a through first connecting cylinder, and a lower side thereof is provided with a flexible annular pad configured to fit with the face.
