Abstract:
The present invention is directed towards apparatuses and methods for the automated measurement of blood analytes and blood parameters for bedside monitoring of patient blood chemistry. Particularly, the current invention discloses a programmable system that can automatically draw blood samples at a suitable programmable time frequency (or at predetermined timing), can automatically analyze the drawn blood samples and immediately measure and display blood parameters such as glucose levels, hematocrit levels, hemoglobin blood oxygen saturation, blood gases, lactate or any other blood parameter.

Abstract:
The present invention is directed toward a method of measuring a blood parameter and, in particular, a glucose measurement system controlled by a novel controller. In one embodiment, the system has a controller, a pump, flush solution in a first reservoir, IV solution in a second reservoir, a first valve, a second valve, and a plurality of tubing placing the pump, reservoirs, and valves in fluid communication with each other. The system operates by establishing a first state where the first state has the first valve open and second valve closed, closing the first valve, instructing the pump to extract fluid from tubing having IV solution therein, sensing a presence of blood at a first location in the tubing, measuring a blood parameter, instructing the pump to re-infuse the extracted fluid back into the tubing, opening the second valve where the second valve permits flush solution to flow from the first reservoir through tubing, instructing the pump to extract fluid from tubing having flush solution therein, closing the second valve, instructing the pump to re-infuse the extracted fluid having flush solution therein back into the tubing, and opening the first valve.

Abstract:
A universal garage door opener (UGDO) that records and recreates a carrier frequency signal from a wide range of commercially available garage door openers. A receiver portion of the UGDO includes a detector for removing a carrier wave of the received carrier frequency signal. The carrier frequency signal is applied to a frequency synthesizer including a dual modulus prescaler divider chain. The carrier frequency signal is divided down by the divider chain and compared to a divided reference frequency signal to determine the carrier frequency. The dual modulus divider chain starts at a maximum divide ratio, and periodically changes the divide ratio until the divided carrier frequency signal is within a predetermined resolution range of the divided reference frequency signal. A JK flip flop is used to hold a phase detect output signal of the frequency synthesizer indicative of the divided carrier frequency signal. A carrier frequency signal from a variable controlled oscillator is applied to the frequency synthesizer to be divided down by the dual modulus prescaler divider chain. The phase detect output signal from the frequency synthesizer is used to adjust the center frequency of the VCO so that the divided VCO frequency signal conforms to the original carrier frequency signal. The output carrier frequency of the VCO is also applied to an amplifier that is responsive to a modulation signal to modulate the carrier frequency in accordance with the originally stored demodulation signal from the carrier frequency signal.

Abstract:
The present invention is a programmable, automated device for the measurement and analysis of blood analytes and blood parameters. The device components are combined in a single apparatus and either programmed to initiate automatic, periodic blood sampling or initiate automatic blood sampling via operator input. The device operates automatically to draw blood samples at suitable, programmable frequencies to analyze the drawn blood samples and obtain the desired blood readings.
