  • Patent number: 5836988
    Abstract: A rate responsive implantable pacemaker generates a metabolic demand parameter which is converted into a corresponding metabolic indicated parameter. The parameter is used to determine certain characteristics related to an exercise period and the patient, including exercise duration and intensity. These characteristics are used to dynamically calculate an exercise recovery period during which the pacing rate is elevated above a rate indicated by the metabolic parameter. Preferably, fuzzy logic circuitry is used for this purpose.

  • Patent number: 5817135
    Abstract: A rate responsive implantable pacemaker generates a metabolic demand parameter such as a thoracic impedance which is converted into a corresponding metabolic indicated parameter. During the conversion, intermediate parameters, such as either tidal volume and respiration rate, or a derivative of the metabolic demand parameter are used by a cross-check circuit to insure that artefacts due for example to stroke volume noise are eliminated. The peak limiter is used to limit the metabolic indicated rate to an acceptable range. Both protection circuits use fuzzy logic components.

  • Patent number: 5626622
    Abstract: An electronic pacemaker generating pacing signals includes both a metabolic rate responsive sensor monitoring a physiological parameter and an activity rate responsive sensor monitoring movement of a patient's body during exercise. The measurements from each of the sensors are used to develop a corresponding rate signal and the two signals are combined to generate a dual sensor rate used to determine the timing of the pacing signals. The physiological parameter may be for example minute volume variation while the body movement may be monitored for example by using an accelerometer. The activity rate responsive sensor output is preferably used as an indication of a transition of a level of exercise, when a faster change in the pacing rate is desirable.

  • Patent number: 4752449
    Abstract: Coagulation is detected in a fluid sample such as blood which has been inserted into a cartridge and operated on by an actuator mechanism. The cartridge may be of either of two types: a plunger sensor cartridge wherein a plunger assembly is reciprocated in a predetermined manner within the fluid sample and the descent of the plunger assembly is sensed to determine coagulation conditions, and a gas flow cartridge wherein gas is passed through the fluid sample to transmit liquid in bubbles and the accumulation of the coagulating liquid from the bubbles is sensed to detect coagulation. An actuator mechanism operates with either one or both types of cartridges to create the conditions under which coagulation can be detected and to sense the coagulation detection conditions. The actuator mechanism reciprocates the plunger assembly and forces gas through the liquid sample to create the bubbles.

  • Patent number: 4663127
    Abstract: A gas flow cartridge in which to conduct analytical coagulation tests on a sample of fluid such as blood includes a tube-like member and a resilient flexible membrane having a slit formed therethrough to divide the tube-like member into an upper reaction chamber in which the test takes place and into a lower reagent chamber which initially contains reagent to be mixed with the sample of liquid upon which the test is to be conducted. The contents of the reagent chamber are forced through the slit in the resilient flexible membrane due to the flexing of the membrane around the slit when pressure is applied. Once the reagent is in the reaction chamber with the sample of fluid, a flow of gas is forced upward through the slit in the membrane during the analytical test.

  • Patent number: 4599219
    Abstract: Coagulation is detected in a fluid sample contained in either a gas flow cartridge or a plunger sensor cartridge, either one of which may be inserted in an actuator mechanism which has the capability of acting on either type of cartridge. Coagulation is detected in the gas flow cartridge by optically sensing the accumulation of coagulating liquid in a foam member at the top of the reaction chamber. In the plunger sensor cartridge, a plunger assembly is raised and released to descend through the sample of liquid in the bottom of the reaction chamber. The plunger assembly descends more slowly upon an increase in the viscosity of the fluid sample due to coagulation. Both cartridges include a lower reagent chamber, an upper reaction chamber, and means initially sealing and thereafter communicating the contents from the reagent chamber to the reaction chamber.

  • Patent number: 4533519
    Abstract: A gas flow cartridge in which to conduct a coagulation-related test uses an elongated pin member movably positioned within a communication opening which separates a reagent chamber from a reaction chamber. A first portion of the pin member has an operative configuration for sealing the communication opening when the first portion is positioned in the communication opening. A second longitudinally displaced portion of the pin member opens the communication opening to further communication therethrough upon longitudinal movement of the pin member. At the commencement of an analytical test, a plug member is moved upwardly to contact the pin member and move the first portion out of the communication opening and the second portion into the communication opening. The upward movement of the lower plug member forces the contents of the reagent chamber through the opened communication opening and into the reaction chamber.

  • Patent number: 3954098
    Abstract: A scan converter storage surface is divided into image spaces corresponding to different points in the heart cycle. Ultrasound echoes from heart structures are plotted in the image spaces by means of special x, y sweeps which are offset to the image spaces by timing circuitry. Separate delay and spacing counters allow the first image to be stored at one interval after detection of the ECG R-wave and successive images to be stored at a another uniform interval. An ECG trace is stored in the first image space with cursors indicating the selected image timing. The scan converter is read out to a TV display. During image build-up, the read and write modes alternate. If desired, the TV sweeps to the scan converter may be attenuated and offset to display a single stored image. Images displayed in sequence provide animation. A self test circuit substitutes a fake ECG and writes bars in the scan converter image spaces using TV sweeps for the scan sweeps.
