  • Publication number: 20240398053
    Abstract: A head-mounted device may have a head-mounted housing containing rear-facing displays that display images for a user when the head-mounted housing is worn by the user. The head-mounted housing may be coupled to the user's head using a headband. The headband may include a first headband portion and a second headband portion that extends from the first headband portion at a fixed angle. Stiffeners may be included in the first and second headband portions. The stiffeners may be formed from braided cords and may be embedded in the first and second headband portions to allow the headband to conform to a user's head when worn. Other stiffeners may be mounted to a surface of the headband to maintain an angle between the first and second headband portions. The ends of the headband may have curved corners, and may appear seamless to the naked eye.

  • Patent number: 12115295
    Abstract: A hemodialysis system including one or more ultraviolet chambers is disclosed. The hemodialysis system including a dialyzer arranged and configured to filter a patient's blood, a hemodialysis machine arranged and configured to pump, move, or the like dialysate through the dialyzer, the hemodialysis machine including an outlet valve and an outlet fluid flow path to pump or move dialysate from the hemodialysis machine to the dialyzer, and an inlet valve and an inlet fluid flow path to pump or receive dialysate from the dialyzer, and one or more ultraviolet chambers arranged and configured to kill bacteria, viruses, or a combination thereof. Thus arranged, by incorporating one or more ultraviolet chambers in strategic areas of the system, the ultraviolet chambers may eliminate, or at least greatly reduce, the possibility of cross-contamination in, for example, the dialysate, and thus eliminate the need for disinfecting the system between treatments.

  • Publication number: 20240256367
    Abstract: Systems, methods, and devices are disclosed herein that provide management of usage of application program interfaces. A computing platform may be configurable to cause detecting a first action comprising an event at a user interface associated with an on-demand application hosted by the computing platform, and making, using a first application program interface (API), an asynchronous call for a data record in response to detecting the first action, the asynchronous call being made to a storage location of the computing platform. The computing platform may also be configurable to cause detecting a second action associated with the on-demand application, and determining if a synchronous call should be performed using a second API, the synchronous call being made in response to determining that a cache does not include the data record. The computing platform may also be configurable to cause generating a result responsive to the second action.

  • Publication number: 20230187063
    Abstract: A medical device is configured to store, in a session memory, data regarding operational parameters of the medical device, changes to the parameters, and physiological data of a patient associated with the medical device. A clinician may select, via a user interface of the medical device, a portion of the session memory to a remote device with a request for assistance regarding a problem occurring at the medical device. The portion of the session may be reviewed at the remote device in a graphical copy of a user interface of the medical device as it appeared when the data was recorded, and a workflow is generated at the remote device and sent to the medical device to assist the clinician in resolving issues at the medical device. A session may be started without an identification of the patient or a medical component, and the identification updated at a later time.

  • Publication number: 20220157445
    Abstract: A method includes receiving a request to activate a medical device. Response to receiving the request, the method includes generating an automatic programming request (APR) for programming the medical device, receiving a message indicating that the APR failed to activate the medical device, and obtaining historical programming records (HPR)s. The method includes determining that parameters in the APR correspond to historical parameters, identifying a set of HPRs including a historical parameter value corresponding to a requested parameter value included the APR, and generating a deviation metric indicating a degree of difference between a secondary parameter value included in the APR and a corresponding historical parameter value. The method includes, responsive to a determination that a deviation metric meets a criticality threshold, changing a drug library record associated with the respective set of deviations and providing an indication to review the changed drug library record.
