  • Patent number: 7828729
    Abstract: A method of measuring blood clotting ability of a patient. A known volume of blood is dispensed on a reference disc of blotter paper, such that at least one reference blotch is formed on the reference disc. The surface area of the reference blotch formed on the reference disc, such that a relationship between the volume of blood and the surface area of the reference blotch can be obtained. An incision is made at the patient. A piece of blotter paper to the incision is applied to the incision to collect blood flowing therefrom, such that at least one blotch is formed on the piece of blotter paper. The surface area of the blotch formed on the piece of blotter paper is measured. The volume of the blood absorbed blood by the blotter paper is calculated according to the relationship between the blood volume and the surface area of the blotch.

  • Patent number: 7803122
    Abstract: Determining the transition between systole and diastole is important for pulse contour-analytical determination of hemodynamic, first of all cardiac output. During the temporal progression of arterial pressure P(t) on which pulse contour analysis is based, the transition between systole and diastole appears as a local minimum. This local slump of the pressure curve downward is very short and is often little recognizable in the actually measured curves due to inaccuracies conditioned by measuring techniques. It was also found that the transition between systole and diastole can be more reliably and accurately determined as the site of maximum curvature of function P(t). Consequently, the invention relates to a device having a calculation unit that comprises evaluation means for detecting the site of maximum curvature of function P(t) in a detection area between the maximum and minimum functional value of the pulse cycle as the site of transition between systole and diastole.

The device features a first sensor configured to attach to a first portion of the patient's body that includes: i)a first electrode configured to generate a first electrical signal fron the first portion of the patient's body; ii)a first light-emitting component; and iii)a first photodetector configured to receive radiation from the first portion of the patient's body after the radiation is emitted by the first light-emiting component and in response generate a first optical waveform. The device also features a second sensor that includes essentially the same components. An amplifier system, in electrical contact with the first and second electrodes, receives first and second electrical signal from the two sensors to generate an electrical waveform.

  • Patent number: 7803121
    Abstract: A monitoring system is provided that enables the monitoring of a heart in a living organism by continuously measuring both pressure and volume in a chamber of the heart, preferably the left ventricle (LV). The pressure and volume measurements are acquired using a single sensing tip and are communicated to a transmitting device to be wirelessly transmitted to a receiving device, wherein they are used to monitor the heart. The system may also incorporate a temperature measurement that can be transmitted with the volume and pressure measurement to provide further data for monitoring. The system may also extract an electrocardiogram (ECG) signal from the volume measurement. This allows the monitoring of up to four signals that can be used to determine the beat by beat state of cardiac output and any changes caused by disease or therapy.

  • Patent number: 7794405
    Abstract: A cuff for a blood pressure monitor has an air bag inflated/deflated as the air comes in/out. The air bag has an inner wall portion located on the inner side in the fitted state of the cuff and an outer wall portion located outer than the inner wall portion, and a side wall portion connecting side end portions of the inner and outer wall portions and folded inwards in the deflated state of the air bag to form a gusset at each side end portion of the air bag. A bonded portion is provided at a region of the air bag in its winding direction around the living body, for reducing expansion of the gusset formed by the side wall portion. Thus, occurrence of lateral displacement of the cuff is prevented, and a highly reliable blood pressure monitor of high performance can be obtained.

    Abstract: This invention relates to a system and method for three-dimensional airway reconstruction, assessment and analysis. Specifically, the invention relates to a system and method for acquiring one- and two-dimensional data regarding a cavity, such as an esophagus or an airway, and manipulating that data to reconstruct a three-dimensional geometrical object representing that cavity. Suitable data collection methods include, but are not limited to, non-ionizing, non-invasive protocols including acoustic reflectometry, such as that performed by a DOS®- or Windows®-based pharyngometer or rhinometer. The resulting three-dimensional geometric object of the subject cavity can be used to diagnose cavity morphology/obstruction, aid in management and treatment of the obstruction, evaluate efficacy of management and treatment of the obstruction and also provide information for use in outcome analysis and forensic and medico-legal evaluation of diagnosis and treatment of cavity obstruction/stenosis.

  • Patent number: 7789829
    Abstract: The sensor system comprises an implantable sensor and a user device associated with it. A sensitive liquid is enclosed in the sensor, into which glucose can penetrate. The viscosity of the mixture of sensitive liquid and glucose is measured. The user device, which controls the measurement and its evaluation, is a portable device worn externally on the skin. The viscosity is measured based on the rotation of a measuring element driven by a driving magnet, both disposed in the sensor. The rotation of the measuring element is analyzed based on its decay behavior following switch-off of the driving magnet. In a second embodiment, the viscosity is measured based on the oscillatory behavior of an oscillating element excited to oscillate by a magnet, both disposed in the sensor. The oscillatory behavior is analyzed based on the decay behavior of the oscillating element following switch-off of the magnet.
