Publication number: 20240016399Abstract: The invention relates to a method and a measuring device for continuously non-invasively determining at least one cardiovascular parameter, preferably the arterial blood pressure, at an extremity containing an artery, the measuring device comprising a receiving element that can be attached to the extremity and is suited to at least partly surround the extremity, and comprising a flexible bubble which is supported on the receiving element, acts on the extremity and is filled with a fluid. According to the invention, an actuator which is suited to vary the pressure in the flexible bubble is placed in or on the receiving element, and the flexible bubble includes a pressure sensor which is in contact with the fluid in the flexible bubble and which is suited to continuously measure the absolute pressure value. The measuring device further comprises a unit suited to measure the pulsations generated by the volume flow in the artery, and a control unit having two different modes of operation, i.e.Type: ApplicationFiled: November 9, 2021Publication date: January 18, 2024Inventor: Jürgen Fortin

Publication number: 20220354376Abstract: The invention describes a measuring system for the continuous non-invasive determination of blood pressure at one or more fingers. The fingers chosen for measurement and the adjacent parts of the palm rest on a supporting surface of a housing, which has the shape of a computer mouse. Inside the housing of the “CNAP Mouse”, i.e. underneath the supporting surface for the hand, the pressure generating system is located. The finger sensors are mounted on the supporting surface for the hand. The forearm and the back of the hand are left free and may be used to place intra-venous or intra-arterial access elements. Since the hand will rest on the supporting surface motion artefacts are largely avoided. Tilting or turning of the sensors is hardly possible since the fit of the sensors and thus the coupling of light and pressure are optimized.Type: ApplicationFiled: July 22, 2022Publication date: November 10, 2022Inventors: Jürgen Fortin, Andrea Fortin, Klaus Popp

Publication number: 20210259566Abstract: The invention relates to a method and an apparatus for validating a continuously measuring, non-invasive blood pressure measuring system equipped with a plethysmographic system capable of obtaining—in a measuring phase—a plethysmographic signal v(t) at an extremity, having a control mechanism to which the signal v(t) from the plethysmographic system is fed, which varies the contact pressure pC(t) at the extremity via a control value u(t), and having an evaluation unit which continuously determines the arterial blood pressure curve pA(t) based on the resulting contact pressure pC(t). According to the invention, the blood pressure measuring system has a coupling interface via which—in a validation or test phase—a signal derived from a previously recorded blood pressure curve can be input into the blood pressure measuring system.Type: ApplicationFiled: May 12, 2020Publication date: August 26, 2021Inventors: Jürgen Fortin, Christian Fellner, Julian Grond, Katja Lerche, Thomas Brunner

Patent number: 10694958Abstract: A wearable device and the accompanying method for the determination of continuous pulsatile BP are described. The absolute values can be obtained in the initial phase and how a transfer function can transform the BP-signal obtain at the finger or wrist to correct BP-values corresponding to the brachial artery and at heart level. The wearable device contains an orthostatic level-correcting element, which can measure the vertical distance between heart level and finger/wrist level, where the actual measurement takes places. The wearable device may be in the form of a ring, a watch, or a bracelet. Further, the wearable device has elements for wirelessly transmitting signals to host devices such as a smart phone, tablet or other computers.Type: GrantFiled: January 7, 2016Date of Patent: June 30, 2020Assignee: CNSYSTEMS MEDIZINTECHNIK AGInventor: Jurgen Fortin

Patent number: 8814800Abstract: A system and method of enhancing a blood pressure signal is disclosed. The volume of an artery in a finger is measured by a photo-plesthysmographic (PPG) system, which produces a PPG signal. This PPG system is placed inside a cuff, and the cuff pressure is controlled by the PPG signal. The portion or component of the PPG signal having a frequency higher than a predefined threshold frequency is then modified or enhanced, such as by multiplying the high frequency component by a calibration factor. A blood pressure signal is then calculated using the cuff pressure and the modified PPG signal. A blood pressure contour curve may then be generated, and a variety of parameters may be calculated using the curve.Type: GrantFiled: October 29, 2010Date of Patent: August 26, 2014Assignee: CNSystems Medizintechnik AGInventors: Jürgen Fortin, Rupert Grüllenberger
