The invention provides a diving face mirror, and relates to the field of diving equipment. The diving face mirror comprises a diving face mirror body, a nose valve is arranged in the diving face mirror body, a nose bridge skirt edge is arranged on the inner wall of the diving face mirror body, the back face of the nose bridge skirt edge is fixedly connected with the inner wall of the diving face mirror body, and the nose valve is located in the nose bridge skirt edge and made of flexible materials. The diving face mirror and the nose valve are made of flexible materials and have excellent sealing performance, the nose valve is located on the nose of the diving face mirror and can effectively seal the nasal cavity and prevent water from entering in the diving process, meanwhile, due to the one-way design of the nose valve, when a diver exhales through the nose, gas can be smoothly discharged, water cannot permeate, and the diving face mirror is safe and reliable. In this way, fog can be effectively reduced, the lenses are kept clear, and the fit degree with the nose bridge is ensured by adopting the ergonomic design of the nose bridge skirt edge. The flexible material of the skirt edge can effectively disperse pressure, so that the oppression feeling brought by a traditional face mirror is avoided, and the comfort is improved.

A nasal valve implant delivery system includes a delivery tool having a handle and a needle extending distally therefrom and configured to hold an implant therein. When loaded in the needle, the implant proximally abuts or is disposed adjacent to a pusher member disposed partially within the needle. A light source disposed within the delivery tool is coupled to an optical fiber carried within a lumen of the pusher member. The delivery tool includes a moveable needle shuttle disposed in the handle that is coupled to the needle. An actuator disposed in the handle is configured to releasably engage with the moveable needle shuttle, wherein the needle shuttle is coupled to one or more springs configured to apply a proximal tensioning force on the needle shuttle, wherein actuation of the actuator retracts the needle proximally into the handle and releases the implant.

An external nasal dilator includes a flexible substrate having a top edge, a bottom edge, a left edge, and a right edge that collectively define an outer perimeter of the external nasal dilator. The left recess is along the left edge and the right recess is along the right edge. The left concave part and the right concave part divide the flexible substrate into two transversely opposite upper leaf-shaped parts and two transversely opposite lower leaf-shaped parts. Comprising the two laterally opposed upper lobes carries an upper resilient member that applies a first expansion force to the inner nasal valve. Comprising the two laterally opposed lower lobes carries a lower elastic member that is different from the upper elastic member and applies a second expansive force to the outer nasal valve. The intermediate section longitudinally separates the upper resilient member from the lower resilient member.

An implant delivery system includes: a handle having a proximal end and a distal end, wherein a longitudinal axis extends in a direction between the proximal end and the distal end; a needle extending from the distal end of the handle, wherein the needle is movable relative to the handle along the longitudinal axis; a pusher member disposed within a cavity of the needle, the pusher member being configured to move an implant disposed within the cavity of the needle; a movable needle shuttle disposed within the handle and coupled to the needle; one or more springs coupled to the movable needle shuttle, configured to apply a proximal tensioning force to the movable needle shuttle; and an actuator configured to releasably engage the movable needle shuttle; wherein the actuator is configured to be actuated to release the movable needle shuttle from the actuator so that the movable needle shuttle moves the needle proximally to at least partially retract the needle into the handle and deploy the implant from the distal tip of the needle.

There is provided a method of laser repair for the internal nasal valve region to improve the nasal airway. The method treats single or multiple sites in all regions that compose the nasal valve, including ablating of soft tissue and cartilage tissue on all sides of the nostril to increase airway patency. Treatments in tissue contact, non-contact, and interstitial modes are provided.

The present application relates to the technical field of medical devices, in particular to a lung function recovery auxiliary device, comprising a chest band for limiting the thoracic cage of a patient and a mask for controlling the breathing of the patient, the chest band comprising a band body and a first strip-shaped air bag arranged on the inner wall of the band body in an inflated state, the mask comprising a mask body for sealing the face of the patient at the mouth and nose, a partition plate being arranged in the mask body to divide the inner cavity of the mask body into a mouth cavity and a nose cavity which are independent of each other, a mouth valve and a nose valve being arranged on the mask body respectively, and a mouth valve control unit and a nose valve control unit being arranged on the mask body respectively to control the opening and closing of the mouth valve and the nose valve, the first strip-shaped air bag being communicated with the mouth valve control unit and the nose valve control unit through air pipes one and two respectively. The present application can assist the patient to perform abdominal breathing or pursed-lip breathing by adjusting the tension state of the chest band.
