Definitions

  • the present invention relates to a measuring device and a provision device for such a measuring device, in particular for recording vital parameters of living beings.
  • the recording of vital parameters can preferably be carried out non-invasively by the measuring device.
  • the provision device is particularly preferably a device which provides radiation and / or pressure for determining blood pressure, in particular a provision device for providing radiation and / or pressure for continuous determination of the intra-arterial blood pressure on at least one finger of a hand.
  • the measuring device is preferably a blood pressure measuring device, in particular a measuring device for the continuous determination of the intra-arterial blood pressure on at least one finger of a hand.
  • the (in particular arterial) blood pressure of a patient is one of the most important measured variables in medical technology, and the known associated, in particular also non-invasive, measurement technology is extremely diverse. This applies above all to measurement technology for the continuous monitoring of blood pressure over a longer period of time, for example in intensive care medicine but also in emergency medicine and during surgical interventions.
  • the blood pressure measuring device is often attached to the patient's limbs, for example an applanation tonometric sensor in the radial artery on the forearm or a photoplethysmographically based on the so-called “sogn. "Vascular Unloading Technique” according to Pegoz operated finger sensor.
  • Such pressure measuring devices are for example from US 4,406,289, US 4,524,777, US 4,726,382, WO 2010/050798 A1, WO 2000/059369 A1, WO 2011/045138 A1, WO 2011/051819 A1, WO 2011/051822 A1, WO 2012/032413 A1 and WO 2017/143366 A1 known.
  • near-infrared light is radiated into a finger and the pulsatile (pulse-shaped) blood flow (actually the changing blood volume) in the finger is determined using the non-absorbed portion captured by a photodetector.
  • the (near-infrared) light is usually generated with the help of one or more light-emitting diodes (LED) that work with one or more wavelengths and with the help of one or more light-sensitive receiver diodes (photodiodes) detected.
  • LED light-emitting diodes
  • photodiodes light-sensitive receiver diodes
  • a control system now keeps the plethysmographically registered flow (or the detected blood volume) and thus the resulting photoplethysmographic signal (volume signal v (t)) constant by applying counter pressure in a cuff (cuff pressure) pc (t) to the finger.
  • This counter pressure pc (t) is usually regulated by a fast valve or valve system in conjunction with a pump.
  • the related control of the valve or the valve system is carried out by a control unit, which is preferably implemented with a microcomputer.
  • the main input signals are the PPG signal v (t) and the cuff pressure pc (t).
  • the pressure pc (t) necessary to keep the PPG signal v (t) constant now corresponds to the intra-arterial blood pressure pa (t).
  • the cuff pressure pc (t) can be changed at least as quickly as the intra-arterial blood pressure pa (t) changes, so that the real-time condition is fulfilled.
  • the upper limit frequency of pa (t) and thus the highest rate of pressure change is above at least 20 Hz, which is definitely a challenge for a pressure control system. It follows from this that the pressure regulation by means of a valve or valve system is advantageously located in the immediate vicinity of the cuff. If the air lines are too long, there is a risk of losing this cut-off frequency condition due to the low-pass effect of the lines.
  • a mechanical valve is known from US Pat. No. 4,406,289 which regulates the counter pressure in the finger cuff with the desired accuracy when it is supplied with a linearly operating pump.
  • the valve is housed in a housing on the distal forearm and thus supplies the finger cuff with the pressure pc (t) via a short tube.
  • No. 4,524,777 describes a pressure generation system for the Vascular Unloading Technique, a constant cuff pressure Pc also being generated with a linear pump, which is superimposed with pressure fluctuations ⁇ pc (t) from a parallel-connected "Shaker” or a "Driving Actuator".
  • US Pat. No. 4,726,382 discloses a finger cuff for the Vascular Unloading Technique which has hose connections for the supply of the cuff pressure pc (t). The length of the air tubes extends to the pressure generation system, which in turn is attached to the distal forearm.
  • WO 2000/059369 A1 also describes a pressure generation system for the Vascular Unloading Technique.
  • the valve system here consists of a separate inlet and a separate outlet valve. While a relatively linear proportional pump must be used in US Pat. No. 4,406,289 and US Pat. No. 4,524,777, this system allows the use of simple, inexpensive pumps, since disruptive harmonics can be eliminated by the arrangement of the valves. Furthermore, the energy consumption of the simple pump can be significantly reduced by the valve principle.
  • a system for the vascular unloading technique is known from WO 2004/086963 A1, in which the blood pressure can be continuously determined in one finger, while the measurement quality is checked in the adjacent finger ("watch dog" function). After a while, the system automatically changes the "measuring finger” with the "monitoring finger”.
  • WO 2005/037097 A1 describes a control system for the vascular unloading technique with several interlinked control loops.
  • WO 2010/050798 A1 discloses a pressure generation system ("front end") attached to the distal forearm with only one valve, to which a finger cuff for the vascular unloading technique can be attached.
  • WO 2011/051819 A1 discloses an implementation of the Vascular Unloading Technique which has been improved by means of digital electronics to increase stability and for further miniaturization.
  • WO 2011/051822 A1 describes a method for the vascular unloading technique in which the measured signals v (t) and pc (t) are processed to increase long-term stability and to determine further hemodynamic parameters.
  • a method for eliminating effects resulting from vasomotor changes in the finger arteries and a method for determining cardiac output (Cardiac Output CO) are disclosed.
  • WO 2012/032413 A1 describes novel finger sensors which have a disposable part for single use. The cuff that comes into contact with the finger is housed in the disposable part for reasons of hygiene, whereas the associated pressure generation and pressure control system is housed in a reusable part. Accordingly, a separable pneumatic connection between the disposable part and the reusable part must be provided here.
  • Such accesses can be blocked by the pressure generation and pressure control system and its attachment.
  • the system can slip or tilt during operation. This can have a detrimental effect on the fit of the sensors.
  • the fit of the sensors would also improve if the finger to be measured or the corresponding hand is in a certain rest position.
  • the publication WO 2017/143366 A1 proposes a measuring system for the continuous determination of the intra-arterial blood pressure on at least one finger of a hand, with at least one finger sensor, with a plethysmographic system, with at least one light source, preferably LED, with one or several wavelengths and at least one light sensor and at least one inflatable cuff, as well as with a pressure generation system with at least one
  • the measuring system having a housing with a surface that serves as a support surface for the at least one finger and the adjacent areas of the palm.
  • the hand rests here on a support under which there are essential components that were attached to the forearm in conventional systems.
  • the cuff is accommodated in a disposable part that can be separated from the housing (and thus from the hand rest).
  • a separable pneumatic connection between the disposable part and the reusable part must again be provided.
  • the light-emitting diodes and photodiodes for emitting and detecting the near-infrared measurement radiation are arranged directly on the finger. If the light-emitting diodes and photodiodes are arranged in a reusable part, there is the problem that the exposed light-emitting elements must be subjected to cleaning and disinfection before they can be reused.
  • the need for an easy-to-clean design restricts the degree of freedom in the design. Otherwise, the need to accommodate the light-emitting diodes and photodiodes in the immediate vicinity of the finger is a limitation of the geometric configuration of the device.
  • the light-emitting diodes and photodiodes are arranged in a disposable item, however, there is the problem that electrical connections are provided between the disposable item and the reusable base unit and that the cost of manufacturing the disposable item increases. The heat input from electrical components with skin contact is also perceived as negative.
