- the compression treatment has proven to be the most effective form of therapy. Doctors, nurses and Physiotherapeu ⁇ th the body part to be treated, in particular the arm or leg of a patient with different compression materials wrapped. It is important that the compression material exerts a pressure on the underlying tissue, which is within ⁇ certain limits.
- the targeted application of medical replacement bandages serves to support the interstitial tissue pressure for improved reabsorption of accumulated fluid. The effectiveness of this measure depends essentially on the applied Pressure profile, wherein the pressure intensity and the local course of the contact pressures are relevant both for the therapy success ⁇ as well as for the prevention of consequential damage.

- the padding material By the padding material, an in-tissue pressure distribution is achieved.
- the pressure measuring sensors are preferably designed such that they measure pressures which act perpendicular to the sensor surface and also pressures which act tangentially to the sensor surface, wherein al ⁇ le possible intermediate values can be detected.
- a water ⁇ tight, sterilizable and disinfectant-resistant coating is applied may preferably insist on chloroprene rubber.
- the metrological connections of the pressure measuring sensors are arranged inside the hollow training extremity and therefore do not influence the measurement result.
- the metrological connections of the pressure measuring sensors can be separated by means of sockets and plugs.
- the respective pressures in real time are measured, registered and Darge ⁇ up on a monitor.
- an evaluation such as a computational ⁇ ner, can freely selectable pressure reference values as desired be deposited. Deviations from a position-specific defined target pressure value can be achieved by signal colors z. B. in the traffic light system with the colors red, yellow and green.
- the training extremity has a releasable support to secure it to a stationary object such as a table.
- the holder has a rotatable axis by means of which the Trai ⁇ ningsextremtician can be adjusted at least between a horizontal and a vertical position.
- Fig. 1 is a schematic side view of
- FIG. 2 is an enlarged sectional view of a section of the training extreme in the area of a pressure-measuring sensor
- Figure 3 is an illustration of a monitor at a ⁇ set of the device according to the invention.
- FIG. 4 is an excerpt of a table of measurements obtained by the device from various therapists
- FIG. 7 shows the distance of the pressure measuring sensors relative to the distal end of the training extremity, which were determined by three different therapists.
- Fig. 1 shows schematically a training extremity 1 in side view.
- a training extremity 1 in side view.
- a plurality of sensors Sl to S16 are mounted whose be fed from ⁇ output signals via an electrical line or of generalized on metrological terminals 2 an evaluation unit, which here consists of a computer 3 and a monitor.
- the pressure measuring sensors S 1 to S 16 are attached at different points of the training extremity 1, namely at predefined distances a measured from the distal end 5 in the direction of the proximal end 6 of the training extremity 1.
- a holding device 7 Attached to the proximal end 6 of the training extremity is a holding device 7, with which the training extremity 1 is attached to a stationary object, such as a patient. can be attached to a table.
- the holding device 7 has a lockable pivoting mechanism 8, by means of which the training extremity 1 is opposite to the stationary object, such as e.g.
- the table (not shown) can be pivoted, at least between a vertical and a horizontal position.
- Fig. 1 is depicted Trainingsextremtician 1 in two Be ⁇ side views in order to illustrate that the pressure measurement sensors S are arranged distributed around the circumference of the Trainingsextremtician 1 to S16.
- the Trainingsextremtician 1 consists material such as polyethylene of hard art and is modeled on the physio logical ⁇ dimensions of a human.
- joints may be provided in the area of elbows or knees, which allow a straight-line flexion of the training extremity.
- a corresponding joint is brought 9 at the location of a knee joint to ⁇ .
- the multicore cable 2, which connects the sensors S 1 to S 16 to the computer 3, is arranged inside the hollow training extremity 1.
- a section of the material of the training extremity 1 is to be seen.
- the pressure measuring surface 10 is substantially in a plane 11, which is defined by the surface of the training extreme in the area of Sen ⁇ sensor S.

- Layer 13 may be applied to a coating which consists of waterproof, wipe-disinfectant and disinfectant-resistant material, for example, chlorine rubber in question, which is commercially available under the brand name "Neoprene”.
- a pressure dressing 14 is then applied, which is to be applied so that a physiologically correct pressure is applied. This pressure is measured by the sensors S and reported via the line 2 to the computer 3.
- the sensors S are preferably constructed in chip technology. They have a pressure / voltage converter 15, which is arranged between a pressure measuring disk 10 and a base 16, which is here re ⁇ alinstrument by a housing wall. The pressure gauge 10 and the base 16 are clamped by springs 17 against each other.

- two views of the training extremity 1 are shown on the monitor 4, with a view of the sensors S1 to S16 in la ⁇ court and with the respectively measured pressure value of the corresponding sensor.
- the measured values of the sensors S1 to S16 are compared with predetermined values and depending on the comparison, the displayed pressure value is displayed in color. For example, too high pressures in the color red, too low pressures in the color yellow and correct pressures in the color green are shown.
- the user has the possibility of further measured values to save to document training resulting ⁇ nisse and training results.
- the therapist can immediately recognize the quality of his Druckapplikati ⁇ on and correct and optimize during the bandaging process.
- the Trainingsextremtician can be respectively inserted so ⁇ represents 1, the ergonomically most favorable for the attachment of the compression means position Gas- is taken.
- the Trai- can ningsextremtician for training and practice purposes each be transported ⁇ time and is available as training and test standard available.
- the table of FIG. 4 shows a section of ge ⁇ measured pressure values of sensors Sl to S7 for different therapists. Double-hatched boxes indicate that the measured pressure is higher than the setpoint, and simply hatched boxes indicate that it is lower than a setpoint range.
