The present disclosure relates to quality control for point-of-care medical diagnostic systems. In various embodiments, the system includes an on-board storage containing a synthetic quality control material, a plurality of sub-systems having a plurality of operating parameters and including a material analyzer, a database storing quality control results that include results of the material analyzer analyzing the synthetic quality control material over time, one or more processors, and at least one memory storing instructions which, when executed by the one or more processors, cause the system to, automatically without user intervention: generate a control chart based on the quality control results, determine that a parameter of the plurality of operating parameters is out-of-tolerance based on the control chart, and adjust at least one of the plurality of sub-systems without user intervention to bring the out-of-tolerance parameter to within tolerance.

Photobiomodulation can be used to treat disorders of the gastrointestinal system. The photobiomodulation can be delivered by an intraluminal device (which can be within the gastrointestinal system) that includes at least one light delivery device configured to provide photobiomodulation; at least one photodetector device to measure reflectance based on the photobiomodulation; a processor to receive a reflectance signal from the at least one photodetector device based on the reflectance measured by the at least one photodetector device and process the reflectance signal; and a wireless transceiver coupled to the processor to transmit at least a portion of the processed reflectance signal. The wireless transceiver can communicate with an external device that includes a wireless transceiver to receive the at least the portion of the processed reflectance signal.

The present technology relates to systems and/or methods for enabling a respiratory device to be configured when a clinician or healthcare professional is remote from the respiratory device. One form provides a method of configuring a respiratory device, the respiratory device comprising a processor configured to control operation of the respiratory device in accordance with a plurality of operating parameters. The method comprises determining a combination of settings for the device from an identifier sent to the device, the identifier corresponding to the combination of settings, and configuring the respiratory device accordingly. Another form provides a method of verifying the configuration of the respiratory device by outputting an identifier corresponding to the combination of settings for the device, and determining the settings from the identifier.

A processing system obtain signals that are generated by or generated based on sensors that are included in one or more hearing instruments. Additionally, the processing system determine, based on the signals, whether a posture of a user of the hearing instruments is a target posture. The processing system generate information based on the posture of the user.

Techniques disclosed herein relate to providing guidance for configuring a medical device to a user in response to detected gestures of the user. In some embodiments, the techniques involve obtaining sensor data indicative of one or more gestures of a user of a medical device, and detecting a configuration procedure being performed on the medical device by the user based on the sensor data, where the configuration procedure includes a sequence of tasks to be performed by the user to configure the medical device. The techniques also involve determining one or more tasks of the configuration procedure that have been performed by the user based on the sensor data, identifying a subsequent task of the configuration procedure to be performed by the user based on the one or more tasks, and generating guidance information for performing the subsequent task of the configuration procedure.

A medical device includes at least one memory device storing data; a communication interface defining a first communication path to allow communications between the medical device and an external device or network; and a hardware key interface defining a second communication path that is separate from the first communication path. A hardware key is configured to be coupled to the meter via the second communication path defined by the hardware key interface. The data on the at least one memory device cannot be modified unless the hardware key interface is physically coupled to the hardware key. The hardware key may include a key code component and conducting lines, where the hardware key interface receives the key code via the conducting lines and the data on the at least one memory device cannot be modified unless the key code provided by the hardware key is validated.

A processor of a medical device configured to communicate with a remote server can be programmed to protect the medical device from exposure to unauthorized or malicious software. A system or method to implement this form of protection can include, for example, at least one processor on the medical device, a control software module that controls the operation of the medical device and is executable on the processor, a data management module that manages data flow to and from the control software module from sources external to the medical device, and an agent module that has access to a limited number of designated memory locations in the medical device. In addition, a hemodialysis apparatus can be configured to operate in conjunction with an apparatus for providing purified water from a source such as a municipal water supply or a well. A system for controlling delivery of purified water to the hemodialysis apparatus can comprise a therapy controller of the hemodialysis apparatus configured to communicate with a controller of a water purification device, and a user interface controller of the hemodialysis apparatus configured to communicate with the therapy controller, and to send data to and receive data from a user interface.
