Abstract: A heatable air delivery tube that maintains the temperature within the tube includes a patient interface end, an airflow generator end, and a heated spiral tube with metal wires that connects the two ends. The patient interface end includes a notch that allows for deformation to better achieve a seal when connected to other tubular connectors. The airflow generator end has a deformable connecting clamp, which allows for self-deformation to secure a snap-fit connection with the airflow generator. The inner diameters of the connectors of both the patient interface end and the airflow generator end are no larger than the tubular connectors they connect to, to ensure a better seal.

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 modular elbow frame assembly for a ventilator, which includes an elbow, a hose, a tubular connector, an external connecting component, a frame, a noise reduction element, a quick-release device. The modular elbow frame assembly for a ventilator can be used in conjunction with a patient interface cushion and a ventilator tube. In this system, the quick-release device is integrally formed with the elbow. The assembly involves a modular design that makes the elbow detachable, allowing the replacement of the elbow with exhaust holes of different numbers or diameters for patients to adjust airflow pressure into the airway. The quick-release device enables the rapid detachment between the elbow and the frame or patient interface cushions. Patients can choose whether to include the noise reduction element and whether to connect the ventilator tube via a hose or directly through a tubular connector.

Abstract: A patient interface pad with good comfort, configured to supply pressurized gas to an airway, includes a support section, an elastic section, and a comfort section. The support section and the elastic section together form a complete patient interface pad; the material of the comfort section includes foam, fabric, or a composite of both; the comfort section has different three-dimensional shapes and is connected to the patient interface pad to form the patient interface pad; the disclosure also discloses a manufacturing method for the patient interface pad with good comfort, as well as the connection method between the comfort section and the patient interface pad which is through an adhesive.

Abstract: A patient interface cushion and specifically a patient interface cushion with fabric, configured to supply pressurized breathing gas to the nasal and oral airways of a user. The patient interface cushion includes a rigid part, configured to support the elastic part, featuring a first opening and a second opening; The elastic part, configured to provide an attachment surface for the fabric part, featuring a third opening in communication with the second opening and a fourth opening allowing the user's nose and mouth to enter the internal cavity of the elastic part. The fabric part, configured to form a sealing area between the lower lip area and the nasal bridge area, featuring a first surface partially connected to the elastic part, a second surface sealing at least a portion of the user's face, and also having an inner edge and an outer edge.

Abstract: A patient interface assembly with optimized connection methods and improved air-tightness. The patient interface assembly forms a complete channel to deliver positive pressure air when connected with an air supply tube and a ventilator. The patient interface assembly includes a patient interface pad, a frame, an elbow assembly, and a quick-release connector. The patient interface pad is fixedly connected to one end of the elbow assembly. The frame is positioned between the elbow assembly and the patient interface pad. The other end of the elbow assembly is connected to the quick-release connector. By reducing the connection steps between parts, the air-tightness of the patient interface assembly is enhanced, and the patient interface assembly is adaptable to various types of frames.

Abstract: A low-noise breathing mask includes an elastic liner, a mask body, and a noise reduction component. The noise reduction component includes a ventilation opening and a muffler. The ventilation opening is provided on the mask body and communicates with a third opening. The muffler is connected to the mask body and covers the ventilation opening. The muffler has a first surface facing the external environment and a second surface opposite to the first surface. The first surface has a first breathable area exposed to the external environment, and the second surface has a second breathable area exposed to the cavity. The muffler also has multiple breathable channels that communicate with the first and the second breathable area, allowing gas in the cavity to be discharged to the external environment through the muffler. The multiple breathable channels in the muffler can render the gas flow smaller and less turbulent.

Abstract: A breathing mask includes a rigid member, an elastic member, and a foam member. The rigid member has an interface on the side away from the user's face for accessing the breathing gas of the continuous positive airway pressure device, and a flared joint on the side adjacent to the user's face. The elastic member is in communication with the inner cavity of the rigid member and is fixedly connected to the flared joint. The side of the elastic piece adjacent to the user's face at least partially abuts the user's nasal bridge area to form an elastic body part, and a support part connected to the elastic body part is provided on the side of the elastic member adjacent to the user's face. The foam member is fixed to the support part and, together with the elastic member, forms a sealing surface for fitting the user's face.

Abstract: A device for delivering gas includes a frame, a gas delivery hose, and a noise reduction component. The gas delivery hose is detachably connectable to the frame. The noise reduction component includes a ventilation port and a muffler. The ventilation port is provided in communication with the cavity of the frame, and the muffler is connected to the frame and covers the ventilation port. The muffler has a first surface having a first breathable area exposed to the external environment, and a second surface having a second breathable area exposed to the cavity. The muffler also has multiple breathable channels connecting the first breathable area and the second breathable area, allowing gas in the cavity to be discharged from the muffler to the external environment. The multiple breathable channels in the muffler can disperse the gas flow, making it less turbulent and reducing the noise generated.
