Abstract: Systems and methods of monitoring a patient. Exemplary methods include receiving sensor data associated with the patient from a plurality of sensors of a patient monitoring device and determining whether the sensor data satisfies one or more trigger conditions. For each of the trigger conditions satisfied, one or more messages are sent to at least one of the patient monitoring device and an external computing device for display thereby to at least one of the patient, a caregiver, and a support person. Satisfaction of one or more of the trigger conditions may indicate the patient has edema and/or is trending toward decompensation. The sensor data may have been collected from a heart rate sensor, an oximeter, an accelerometer, and/or a sensor configured to detect a distance around a limb of a patient. In some embodiments, the trigger conditions are provided by the patient, caregiver, and/or support person.

These include a bearing-centered probe, a spring loaded wheel-centered probe, a multi-part probe for curved tube inspection having limited excursion ball joints connecting the probe parts, and a 3D printed probe including features that are incapable of being manufactured through conventional casting or machining processes.

Abstract: A portable health data tool permits a health care provider to assimilate and display a plurality of health care data from a patient and to associate the data with patient identifying information all stored in a memory contained in the tool. The tool includes a code reader for reading patient information into the tool from a bar code or other coded tag. The tool is associated with a plurality of different data assimilation devices stored with the tool's housing, including but not limited to, instruments for measuring, temperature, blood pressure, two-finger or lead wire ECG data, pulse oximetry data, sound data and picture data obtained from an optional digital camera integrated within the housing. The tool further includes data receiver and/or transmitter ports, which may be wireless or cable ports, for transferring data between the health data tool and a separate computer system that stores patient records.

Abstract: A monitoring device to be used in conjunction with a patient's airway. Some embodiments of the monitoring device include at least one sensor assembly configured to detect inhaled and exhaled airflow and an optional communications subassembly configured to transmit measurements to at least one external computing device. Other embodiments include at least one sensor assembly configured to detect a measurement indicating airflow from the patient's lungs and at least one processor configured to detect whether the airflow is associated with medication administration or measurement of breathing characteristics. Some embodiments include a circuit that allows patient information to be analyzed by an external computing device and/or the monitoring device to determine whether the patient's breathing has declined indicating a medical problem. Optionally, the monitoring device may include a display for displaying whether the airflow measurement indicates a good outcome, a potential concern, or a serious condition.

Abstract: An interface protocol for patient monitoring systems includes a Dual Serial Bus (DSB) interface. The DSB interface includes a first serial protocol that is USB, Firewire, or Ethernet protocol and a second serial protocol that is a low power serial (LPS) protocol. DSB interfaces provide for communication between DSB Hosts and DSB Devices and allow for the transfer of operating and battery charging power from DSB Host to DSB Device. In addition, the DSB host contains a switched Auxiliary Voltage Supply (AVS) which can provide up to 15 W of power to DSB devices for battery charging or other high power needs. The DSB interface eliminates the need for multiple cables for different parameter sensing devices as there is only one type of connector and, accordingly, reduces the risk of damage caused by inadvertently plugging a parameter sensing device into the wrong receptacle.
