Abstract: A system for providing mechanical ventilation to a plurality of patients using a single ventilator is provided. The system includes a first branched adapter may be coupled to a ventilator, the first branched adapter having a plurality of branches and configured to divide a ventilator gas stream into a plurality of gas streams for delivery to a respective plurality of patients. The system includes a pressure regulator in fluid communication with one branch of the first branched adapter and with one patient, the pressure regulator being configured to reduce the pressure of the gas stream reaching the patient such that it is less pressurized than the ventilator gas stream. The system includes a second branched adapter may be coupled to a ventilator, the second branched adapter having a plurality of branches and configured to unite expired gas streams from the plurality of patients into a single expiratory gas stream.

Abstract: An ear splint for an ear is provided having a central portion having an exterior surface defining a first topology that is configured to dwell within an anterior scaphoid section of an ear, and a wing portion extending from the central portion and integrally formed therewith and at least partially surrounding an outer periphery of the central portion. The wing portion includes an exterior surface defining a second topology and is configured to be positioned along a postauricular area of the ear. The first magnetic device is disposed in the central portion and the second magnetic device is disposed in the wing portion. The magnetic retention feature exert a magnetic attractive force between the central portion and the wing portion such that at least a portion of the exterior surface of the central portion and at least a portion of the exterior surface of the wing portion contact the ear.

Abstract: Prosthetic tegmen plates are provided. The prosthetic tegmen plates include a body that defines at least one engagement surface that substantially conforms to a region of a corresponding surface of a subject's temporal bone having a tegmen defect. The prosthetic tegmen plates are configured to cover the tegmen defect. Methods for manufacturing prosthetic tegmen plates by additive manufacturing and surgically implanting prosthetic tegmen plates are also provided.
