Abstract: An adjustable nasal dilator designed to fit on a patient's nose and apply an outward expansion force to enhance airflow through the nasal passages. The device includes a supporting member, a fitting assembly, and an adjusting assembly. The supporting member has at least two opposing ends configured to laterally fit against both sides of the patient's nose. The fitting assembly includes first connecting portions attached to the nose and second connecting portions attached to the two ends of the supporting member, which mutual engage during use. The adjusting assembly allows the user to independently control the expansion level of the device, representing a major innovation over existing products. Through its adjusting mechanism, the adjusting assembly regulates a tensioning member to vary the angle of the left and right ends of the supporting member.

Abstract: A headgear for use in the Positive Airway Pressure field includes an inner layer, a bonding layer, a padding layer, film layers, and an adhesive. The inner layer is configured to be at least partially in contact with a patient's skin during use, while the bonding layer is configured to adhere an outer side of the headgear, which comes into contact with the air, to a fixed part by folding the headgear, thereby tightening or loosening the headgear. The padding layer, placed between the inner layer and the bonding layer, increases thickness. The film layers are provided between the inner layer and the padding layer, as well as between the padding layer and the bonding layer. The adhesive is configured to bond the layers together. The headgear has at least three layers and is made of at least two types of textile materials.

Abstract: A suction device includes a negative pressure generator, a connector and a mask; the negative pressure generator including a housing and a piston rod. 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 includes 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 a sealing ring. An upper side of the mask is provided with a through first connecting cylinder, and a lower side is provided with a flexible annular pad configured to fit with the face.

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.
