Abstract

On an anti-blackout suit (1) operating according to the hydrostatic principle, a pressure measurement cell (3) is arranged at, for example, the lowest point of a liquid-conveying vein (2) which, by its internal pressure, generates the circulation stress required for the anti-blackout suit (1). Pressure changes arise as a result of the volume changes, during respiration, in the person wearing the anti-blackout suit (1), and these pressure changes are measured by the pressure measurement cell (3) and, for example, transmitted to an evaluation apparatus via a cable (5). Both a display device and also a memory device can be linked to the evaluation unit.

Claims

1. A device for measuring the respiration rate and the breathing pattern of a person wearing an anti-blackout suit operating according to the hydrostatic principle, with liquid-conveying veins (2) which can extend substantially the entire length of the anti-blackout suit, an orthostasis suit or a hypoxia garment, characterized in that

a pressure measurement cell (3) is present which is inside a liquid-filled, liquid-tight sheath and is in pressure-communicating connection with one of the veins (2), or with the inside of the garment,

an evaluation apparatus (4) is present which evaluates and processes the measurement values of the pressure measurement cell (3) and is set up in such a way that it can feed both a display device (6) and a memory device (7).

2. The device as claimed in patent claim 1, characterized in that the pressure measurement cell (3) is arranged in the inside of a vein (2) of an anti-blackout suit.

3. The device as claimed in patent claim 1, characterized in that the pressure measurement cell (3) is arranged in the inside of a vessel which is connected via a tube to a vein (2) of the anti-blackout suit in such a way that it communicates with this vein (2) in a liquid-communicating and pressure-communicating manner.

4. The device as claimed in patent claim 2 or 3, characterized in that the pressure measurement cell (3) is situated at the level of the lowest point of the vein (2) of the anti-blackout suit.

5. The device as claimed in patent claim 2 or 3, characterized in that the pressure measurement cell (3) is connected via a cable (5) to the evaluation apparatus (4), which cable (5) transmits to the evaluation apparatus (4) the values determined by the pressure measurement cell (3).

6. The device as claimed in patent claim 2 or 3, characterized in that an optocoupler is present and is linked to the pressure measurement cell (3), said optocoupler transmitting to the evaluation apparatus (4) the values determined by the pressure measurement cell (3).

7. The device as claimed in patent claim 2 or 3, characterized in that a radio apparatus is present and is linked to the pressure measurement cell (3), said radio apparatus transmitting to the evaluation apparatus (4) the values determined by the pressure measurement cell (3).

8. The device as claimed in patent claim 1, characterized in that a display device (6) is present and is linked to the evaluation apparatus (4).

9. The device as claimed in patent claim 1, characterized in that a memory device (7) is present and is linked to the evaluation apparatus (4).

10. The device as claimed in patent claim 1, characterized in that both a display device (6) and also a memory device (7) are present and both are linked to the evaluation apparatus (4).
