Abstract: A diffuser for use with a wound retractor and configured to deliver gases includes an interface tube for connecting to a gases supply and a diffuser interface positioned at a proximal end of the interface tube, the diffuser interface configured for delivering gases received from the gases supply through the interface tube, and the diffuser interface comprising a diffusion mechanism configured to deliver gases in a diffusion direction. A wound retractor with an integrated diffuser is also disclosed. The wound retractor includes an upper ring, a lower ring, a sleeve extending between and connecting the upper ring to the lower ring, and an integrated diffuser interface having a gases inlet and a diffusion mechanism.

Abstract: A server system for regulating access to a health record of an individual includes a communications subsystem, a logic subsystem operatively coupled to the communications subsystem and configured to execute instructions, memory operatively coupled to the logic subsystem and holding user-interface instructions that, when executed by the logic subsystem, send information via the communications subsystem for presenting a user interface. In this embodiment, the user interface includes a list of one or more items in the health record to which an application has requested access, and for each of the one or more items, a configuration-indicating element distinguishing whether the application is configured to service the individual if access to that item is denied. The user interface further includes for each of the one or more items, one or more presettable selection elements enabling a marshal of the health record to authorize or withhold access to that item.

Abstract: A method to regulate access to a health record of an individual includes receiving a request from an application, the request identifying an item in the health record to which access is requested. The method further includes presenting the request to a marshal of the health record via a user interface and receiving a response from the marshal of the health record via the user interface, the response indicating whether access to the item is authorized or withheld. The method further includes granting the application access to the item if the response indicates that access to the item is authorized, and denying access to the item from the application if the response indicates that access to the item is withheld.
