An angiographic injector system and a method of controllably delivering medical fluid to a patient from an angiographic injector system are disclosed. A multiple processor control system is used to actively control the injection process and to monitor sensed functions of the system. The multiple processors provide dual redundancy safety circuits for critical control functions such as syringe motor drive speed and current. A motor / servo-amplifier nested control function is also disclosed. A unique method and apparatus are disclosed for establishing injection parameter default values just prior to an injection procedure that are based on physiological values of the patient to be treated. The injector system uses an interactive display panel that presents sequenced set-up screens to the user and which enables the user to select injection procedures, parameters and other modes of operation directly through the interactive panel.

An integrated system for assessing wound exudates from the wound of a patient is described. The system may contain functionality to detect, process and report various wound parameters. The system also may make treatment determinations based on these findings. The system may detect one or more physiological values of the wound exudates from the wound of the patient. The system may means for comparing the one or more detected physiological values to predetermined physiological values in order to obtain a comparison result in real time. The system may include a processor 15 which provides an electronic signal based on a comparison result in which the electronic signal may correspond to guidelines for treating the wound 13. The system may be integrated with other wound treatment devices, such as negative pressure wound therapy devices (NPWT) 9.

A stand-alone system for assessing wound exudates from the wound of a patient is described. The system contains functionality to detect, process and report various wound parameters. The system also may make treatment determinations based on these findings. The system may detect one or more physiological values of the wound exudates from the wound of the patient. The system may also compare detected physiological values to predetermined physiological values, in order to obtain a comparison result in real time. The system may include a processor (15) which provides an electronic signal based on the comparison result in which the electronic signal may corresponds to guidelines for treating the wound (3). The system described may be an accessory, which may be used on its own, or in conjunction with other wound treatment devices (9).

Enhanced security is provided in a system comprising a medical device and a monitoring device. The medical device is configured for implantation into a living organism, and comprises processing circuitry and an interface for communicating with the monitoring device. Access to the medical device by the monitoring device is controlled based on measurement of one or more physiological values of the living organism by at least one of the two devices. In an illustrative embodiment, the medical device and the monitoring device are configured to include respective physiological value sensors for measuring respective dynamic physiological values of the living organism. The medical device is further configured to determine if the dynamic physiological values are sufficiently similar to one another and to grant or deny the monitoring device access to the medical device based on the determination.

A key establishment protocol for securing wireless body sensor networks using environmental data for nonce values. To establish a secure communication between sensors in a sensor network using environmental data, the protocol measures a first environmental value at a first sensor and a trusted third party. A second environmental value is measured at a second sensor and the trusted third party. The trusted third party then sends to the second sensor a first authentication construct comprising the second environmental value, wherein the second environmental value is used by the second sensor to prevent replay attacks of messages between the trusted third party and second sensor. The trusted third party also sends to the first sensor a second authentication construct comprising the first environmental value, wherein the first environmental value is used by the first sensor to prevent replay attacks of messages between the trusted third party and first sensor.
