Definitions

  • the invention relates to a measuring device according to the preamble of claim 1 and to a measuring method according to the preamble of claim 10.
  • the standard therapy for patients with heart failure and chronic hypertension is the treatment with antihypertensive drugs.
  • the right dosage and the right combination of prescribed medications must be evaluated individually for each case.
  • the most important basis for the evaluation is a daily blood pressure measurement performed by the patient. Medication evaluation based on daily individual measurements is problematic because blood pressure is not constant throughout the day and is influenced by many factors such as body position, activity, the body's post-daytime rhythm, stress, metabolic activity and food.
  • the invention has for its object to provide a measuring device, based on their measurement results waiving a blood pressure measurement, reliable statements about the effectiveness and / or the duration of action and / or the dosage of at least one drug and / or on the medik kameinein frosting a Patients can be made. Furthermore, the object is to propose a corresponding measuring method.
  • the invention has recognized that the most important class of antihypertensive drugs, especially ACE inhibitors and AT2 receptor blockers, affect the vascular tension of blood vessels. Based on this finding, the further realization is that the measurement of the vascular tension is a very specific parameter for the effect of this class of drugs, as the blood pressure. Since the vascular tension, like the blood pressure, depends on various factors, such as the body position, the activity, the daytime post-rhythm of the body, stress, the metabolic activity and the ingested food, the invention proposes a measuring device designed as a long-term measuring device with which the pulse wave transit time and / or the pulse wave velocity and / or the pulse waveform can / can be measured over a relatively long period, preferably over 24 hours, very particularly preferably regularly.
  • the medication intake behavior of a patient can be made by a corresponding evaluation of the pulse wave transit time and / or the pulse wave velocity and / or the pulse waveform. It is very particularly preferred if the control means of the measuring device control the measuring means in such a way that these measurements carry out at least one of the aforementioned parameters continuously or at certain, preferably regular, intervals. It is very particularly preferred if measurements can be carried out at intervals of 15 to 30 minutes, preferably at intervals of 20 minutes, in order to obtain a good overview of the vessel voltage over a relatively long period of time.
  • the pulse rate can be used to check the plausibility of the measurement results.
  • measurement results can be disregarded or weighted differently, which are measured at a time at which a conspicuous, for example, very high pulse rate is measured which is at an exception, for example a sudden stress or a sudden indicates physical effort.
  • the measuring device evaluates the recorded measurement results with the aid of integral analysis means.
  • the analysis means may be designed such that they perform an evaluation of the vessel wall tension, in particular of a patient's arterial blood vessels, on the basis of the measurement results.
  • the measuring means and / or the analysis means may be part of common logic means that determine the pulse wave velocity by a signal analysis of the detected pulse shape.
  • the pulse shape is in the form of a double pulse, which results from the reflection of the pulse in the arterial vasculature.
  • the vascular tension has a significant influence on the time interval of the amplitudes of a double pulse.
  • measuring means determine the pulse wave velocity and / or the pulse waveform on the basis of a transmission or reflection measurement.
  • a body part for example a finger of a patient, is illuminated with the aid of an infrared-emitting LED.
  • the optical transmission is measured by means of a photodiode, which changes due to a volume expansion due to a pulse wave propagation.
  • a reflection measurement can also be carried out.
  • the invention also leads to a method for determining a long-term profile of the pulse wave transit time and / or the pulse wave velocity and / or the pulse waveform, in particular with the aim of determining the vessel wall tension of preferably arterial blood vessels; this in turn with the aim of analyzing the efficacy and / or the duration of action and / or the dosage of at least one drug and / or to evaluate the drug intake behavior of a patient.
  • the pulse frequency is used for plausibility of measurement results.
  • the pulse wave velocity is determined on the basis of a signal analysis of a detected double pulse shape.
  • the relative position of two amplitudes of the double pulse can be determined by a signal analysis processor. Immediately from knowledge of the relative amplitude position, a statement about the vessel wall tension can be made.
  • the measuring device is fixed to a finger and / or a hand and / or on an arm joint and / or on an earlobe and / or toe of a patient and / or if the measurement of the pulse wave transit time and / or the pulse wave velocity and / or the pulse waveform is performed at one of these locations. It is also conceivable to select other body locations for positioning and / or performing the measurement.
  • the invention also leads to the use of a previously described device for evaluating the vessel wall tension and / or the efficacy of at least one drug and / or the duration of at least one drug and / or drug intake behavior of a patient and / or the dosage of at least one drug.

  • the measuring device 1 comprises only schematically indicated fastening means 2 for fixing the measuring device 1 to the human body.
  • the measuring device comprises measuring means 3.
  • the measuring means 3 in turn comprise an LED light source 4 for emitting infrared radiation 5 as well an IR intensity sensor 6 for detecting the transmission of the infrared radiation 5 by a human finger 7.
  • the transmission decreases when a pulse wave (tube wave) through a blood vessel (in particular an artery) between the LED light sensor 4 and the sensor 6 through running.
  • the measuring means 3 are associated with control means 8, which cause a measurement of the pulse wave velocity and the pulse waveform every 20 minutes over a period of 24 hours.

Due to the heartbeat of the heart 15, however, the pulse wave is not emitted exclusively in the direction of finger 7, but also in the Abdominal cavity into it. There it meets an arterial branch 18 (reflection point) at which it is reflected and only then propagates in the direction of finger 7.
