  • Patent number: 4969868
    Abstract: A microelectronic ionized device for curing oral cavity diseases being a special kind of toothbrush comprising a brush head, brush handle and a cavity in the handle for retaining a battery. A group of special bristles serving as a cathode at the brush head is connected in series with the battery and a metal plate which serves as an anode adjacent the brush head. During toothbrushing, saliva and/or ionized toothpaste fills the space between the cathode and anode to form a return circuit. When this occurs the trace elements in the special bristle releases ions essential for cementosis while at the same time produces a microcurrent to stimulate such soft tissues as the oral cavity and gums, thus achieving an effect of physical massage. Consequently, various kinds of diseases of the oral cavity are cured. The use of ionized toothpaste enhances the curing effect.

  • Patent number: 4966580
    Abstract: A device for administering oral fluid to a patient from a container (18) has a nipple (14) connected to the container (18) by a tube (16). The nipple (14) is held on the patient's tongue. A valve (22) opens in response to the patient sucking or pressing the nipple to initiate a flow of fluid in the tube (16). A detector (92) responds to this flow and switches on a peristaltic pump (90) for a period determined by the setting of a controller (102) to deliver positively a suitable bolus of 2 to 6 ml to the patient. To give the patient time to swallow the bolus, the detector (92) is inhibited for a predetermined delay period after termination of the bolus and over the same delay period, the tube (16) remains pinched or clamped.

  • Patent number: 4953559
    Abstract: A catheter for endocardial biopsy comprises a distal portion provided with biopsy forceps including two jaws which are movable relative to each other between an open position and a closed position, and means which are operable from the proximal end of the catheter for causing the movement of the jaws. The two jaws of the forceps are of electrically conductive material, are insulated from each other, and are connected respectively to two terminals situated at the proximal end of the catheter so that, when the jaws are in their open position, they can be used as electrodes for identifying the point of origin of a ventricular arrhythmia. It is thus possible to carry out an endocardial biopsy in apparently normal patients with ventricular arrhythmia, tissue samples being taken both in correspondence with the zone of origin of the arrhythmia and in correspondence with other zones, immediately after the identification of the zone of origin.

  • Patent number: 4949722
    Abstract: A diagnostic method or process is disclosed for determining one or more parameters which are characteristic of the adhesiveness of blood platelets of a human patient. A blood sample is collected from a venipuncture of a patient through a filter which comprises a load of glass beads or spheres placed in a medically acceptable plastic, polyvinyl or like, tube. The time is measured that it takes for a predetermined volume of the sample to be collected through the filter. For control, a blood sample is also collected without passing the sample through a filter. The number of platelets per unit volume in each sample is determined by conventional counting techniques. From the measured platelet counts and the measured time period, the rate (in platelet count per second) is calculated at which the filter apparatus retains the blood platelets of the patient. The percentage of the retained platelets as compared to the unfiltered blood sample is also calculated.
