Filed:

May 15, 2000

Appl. No.:

09/570683

Inventors:

Wayne Y. Menzie - Arlington MA
John Schafer - North Hampton NH
Alan M. Cohen - Newton MA

Assignee:

Boston Medical Technologies, Inc. - Wakefield MA

International Classification:

A61B 50205

US Classification:

600513, 607 25

Abstract:

A medical testing system includes telemetry features whereby physiological data collected by a collection device at a medical facility is transmitted to a remote processing center for analysis by a trained analyst to provide a test result. In one embodiment, the collection device is a heart rate monitor capable of collecting data with which heart rate variability can be assessed. The heart rate monitor includes a display on which is displayed a waveform showing the breathing performance of the patient during data collection along with standards against which to compare the waveform in order to determine the extent to which the patient followed a predetermined breathing regimen during data collection. The operator of the monitor can use the performance waveform to assess how well the test was taken (i. e. , how well the patient complied with the prescribed breathing regimen) and can accept or reject the physiological data accordingly.

International Classification:

G01N033/00

Abstract:

A glucose meter includes means for processing a blood sample to provide a glucose measurement and a communication interface to send and receive data including the glucose measurement to a remote processing center. The processing center collects and processes a plurality of glucose measurements to provide a modified method for processing a blood sample in order to provide an adjusted glucose measurement. In one embodiment, the modified blood sample processing method is a function of a permissible glucose deviation for the patient and in another embodiment, the modified blood sample processing method is a function an aging factor indicative of test strip variations over time.

Also described is a medical testing telemetry system including two processing centers, with each collection device being capable of communicating with both processing centers. Each collection device randomly chooses one of the processing centers for analysis of the collected physiological data. The two processing centers are interconnected in order to permit physiological data and test results to be replicated and stored at both sites.

International Classification:

US Classification:

Abstract:

A prime mover has a programmable control system for applying a material, such as a liquid herbicide onto programmed locations in an agricultural field, by creating a program manually on an initial pass of the field in relation to the position of the prime mover, and storing the information in a program for subsequent control in subsequent passes of the prime mover for repeating operations. A microprocessor having a programmable memory is utilized with manual controls for operating a sprayer when weeds are visible, and then correlating the position of the prime mover and the operation to be performed in a subsequent operation and permitting the memory to control the on and off applications of the sprayer. The unit makes use of low cost microprocessors with programmable memories and permits a low cost repeatable operation merely by providing a reference starting position, and a known path in which to travel.
