  • Publication number: 20090131759
    Abstract: A wearable platform embodied in a belt or patch provides physiological monitoring of soldiers during field operations or trauma victims at accident sites and makes health state assessments. The platform includes sensors for heart rate, body motion, respiration rate and intensity, and temperature and further contains a microprocessor and short range transmitter. An analog circuit running an algorithm obtains the R-wave period from the EKG signal and produces electrical pulses with the period between pulses corresponding to the R-wave period. A rule based processing engine having an evaluation algorithm is capable of making a medical evaluation of subject condition and determines a confidence level for the evaluation. The rules are subject to variation depending upon the subject population. The information is communicated wirelessly to a local hub for relay to a remote monitor.

  • Publication number: 20070293781
    Abstract: A wearable platform embodied in a belt or flattened patch-like central body shaped to conform to the abdomen provides physiological monitoring of soldiers during field operations or trauma victims at accident sites and makes health state assessments. The platform includes sensors for heart rate, body motion, respiration rate and intensity, and temperature and further contains a microprocessor and short range transmitter. The respiration sensor uses conductive ink in a novel manner. A small square of the ink is coated on an arched structure so that flexing of the arch either to increase or decrease its radius of curvature modifies the resistance of the structure. This is utilized to set the unstressed resistance of the arch structure and to allow a greater range of resistance values capable of measuring distortions in different deformations of the arch. The respiration sensor supplements the motion information provided by an accelerometer sensor.

  • Publication number: 20070233004
    Abstract: Various methods and devices for driving fluid from a syringe are provided. In one exemplary embodiment, a syringe driver is provided having a frame that is adapted to seat a syringe, a driver that is slidably disposed within the frame and that is adapted to seat a plunger of a syringe, and a puller that is slidably disposed within the frame and that has a latch formed thereon for mating to an engagement element on the frame. The device can also include a force-delivery element, such as a constant force spring, that is coupled to and extends between the driver and the puller.
