Publication number: 20250235655Abstract: 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.Type: ApplicationFiled: January 18, 2024Publication date: July 24, 2025Applicant: DCSTAR INCInventor: David LUO

Publication number: 20250195811Abstract: 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.Type: ApplicationFiled: November 18, 2024Publication date: June 19, 2025Applicant: DCSTAR INCInventor: David LUO

Publication number: 20250195817Abstract: A ventilation elbow assembly, which is directly connectable to a face mask. The elbow assembly includes an elbow, connector, ventilation port, noise reduction device, and quick-release connector. The elbow has a first interface, second interface, and annular channel. At the first interface, there is at least one stepped portion, which is configured to connect to the face mask and seal pressurized gas. A baffle is provided at the first interface, limiting frame movement relative to the face mask and elbow. The assembly also includes an anti-asphyxiation valve to prevent the patient from asphyxiation without continuous positive pressure in the elbow. With a connector, the elbow can first connect to the connector before the face mask, expanding the range of movement of the elbow assembly relative to the face mask. This is configured to increase the range of movement of the elbow assembly relative to the face mask.Type: ApplicationFiled: December 14, 2023Publication date: June 19, 2025Applicant: DCSTAR INCInventor: David LUO

Patent number: 12311106Abstract: 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.Type: GrantFiled: May 20, 2024Date of Patent: May 27, 2025Assignee: DCSTAR INCInventor: David Luo

Patent number: 12313197Abstract: A hose connector with an adjustment structure to securely connect patient interface components to a machine in Continuous Positive Airway Pressure therapy. The hose connector includes a first connector end to connect an external tubular connector, a second connector end to connect a hose, and a sidewall that encircles and forms the first connector end and the second connector end. The sidewall has an interior and an exterior, with a gripping portion on the exterior. The first connector end, which is configured to connect to the external tubular connector, includes a portion of the sidewall, a chamber that is configured to accommodate the hose connector, an opening, an abutment surface, and a retaining structure. At least one adjustment structure is provided on the opening. Furthermore, the first connector end of the hose connector with the adjustment structure is made of a resilient first material.Type: GrantFiled: January 18, 2024Date of Patent: May 27, 2025Assignee: DCSTAR INCInventor: David Luo

Patent number: 12274829Abstract: A respiratory mask configured to adapt and comfortably seal according to the facial features of different users. The respiratory mask includes a support chamber, a cushioning part, and a comfort layer. The support chamber has curved sidewalls and two circular openings of varying sizes. The cushioning part includes of an elastic body and a sponge body. The fixed side of the elastic body is connected to the support chamber. The sponge body has a curved side and a connecting side that connects to the elastic body. The first side of the comfort layer is configured to make partial contact with the user's face, while the second side of the comfort layer connects to the sponge body. Both the cushioning part and the comfort layer are configured to deform, collaboratively ensuring a tight seal around the user's face.Type: GrantFiled: November 15, 2023Date of Patent: April 15, 2025Assignee: DCSTAR INCInventor: David Luo
