Description

FIELD OF THE INVENTION

The present invention relates to a device for preventing fatigue in a person, a drone for receiving such a device, a method for preventing fatigue in a person, a vehicle comprising such a device and a machine tool or processing station for producing a workpiece.

BACKGROUND OF THE INVENTION

It is known that lack of oxygen can lead to fatigue. If a person is already exhausted, a lack of oxygen can increase fatigue and even lead to the risk of unconsciousness. The phenomenon of microsleep is well known, in which exhausted drivers can fall into a short sequence of fainting. There is an acute risk of accidents here.

SUMMARY OF THE INVENTION

Lack of oxygen can cause a person to feel tired. Loss of consciousness due to a lack of oxygen does not necessarily have to have dramatic consequences. However, if the person concerned is performing a responsible task at this moment, such as driving a vehicle or operating a machine tool or a processing station to produce a workpiece, there is a risk of danger.

Fatigue that leads to a lack of concentration or even loss of consciousness can pose a danger to the person and those around them or to the machines and equipment entrusted to them.

One task is therefore to provide a device through which fatigue can be prevented and/or the detection of a corresponding risky situation is made possible in order to prevent unconsciousness or weak reactions.

As a first aspect of the invention, there is provided a device for preventing fatigue in a person, comprising: a sensor for determining the oxygen content of the person's blood and/or a sensor for determining the person's reaction speed and/or a device for supplying oxygen with a nozzle.

As a second aspect of the invention, a drone for recording a device according to one of claims 1 to 5 is provided.

As a third aspect of the invention, a vehicle comprising a device according to one of claims 1 to 5 is provided.

As a fourth aspect of the invention, a machine tool or a processing station for producing a workpiece is provided, the machine tool or the processing station comprising a device according to one of claims 1 to 5.

As a fifth aspect of the invention, a method for preventing fatigue of a person is provided, comprising the steps: determining the condition of the person with regard to the person's tiredness and/or determining the oxygen level of the person and/or determining the speed of the person's reaction and/or or if fatigue is detectable, supplying oxygen to the person and/or if oxygen deficiency is detectable, supplying oxygen to the person.

Exemplary embodiments are described in the dependent claims.

According to an exemplary embodiment of the invention, a device is provided, wherein the device comprises a sensor for determining physiological or physical characteristics of the person and/or wherein the sensor determines the oxygen content of the person's environment and/or the oxygen content of the person in the blood determines and/or wherein the sensor determines the heart rate of the person and/or wherein the sensor determines whether the person keeps their eyes closed.

The person's heart rate can be used to determine whether the person is about to fall asleep. If a slow reaction speed is detected, it is also a warning sign. If such warning signals are present, oxygen can be supplied at the latest.

According to an exemplary embodiment of the invention, a device is provided wherein the nozzle is movable and/or wherein the nozzle is directed toward the person's nostril.

According to a further embodiment of the present invention, a device is provided, the device having a sensor which can determine the location of the nostril in order to align the nozzle with the nostril.

In a further embodiment according to the invention, a method is provided, comprising the steps: determining the Location of the person's nostril by a sensor and/or aligning the nozzle according to the location of the nostril determined by the sensor.

According to an exemplary embodiment of the invention, a device is provided, wherein the device is a tactile surface which determines whether the person is exhausted, for example by determining the degree of sweating, blood pressure and/or heart rate.

One idea of the invention can be seen as providing a device such that a person's tiredness is detected by a sensor. For this purpose, for example, the oxygen content of the person's blood and/or the oxygen content of the person's environment can be determined. Alternatively, the person's behavior, for example how quickly the person reacts to situations or whether the person's eyes are closed, can be determined in order to be able to determine a dangerous situation.

The individual features can of course also be combined with one another, which can sometimes produce advantageous effects that go beyond the sum of the individual effects.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

1 shows a vehicle 1, which is driven by a person 6, in which there is a sensor 3 which detects the oxygen content in the vehicle 1. If the oxygen content in the vehicle 1 falls below a critical value, oxygen is blown into the passenger cabin of the vehicle through nozzles 2. This can prevent the person 6 from becoming tired due to a lack of oxygen. The device according to the invention can in particular prevent so-called “microsleep”.

2 shows a processing machine 4 on which a person 6 works, with nozzles 2 being arranged, whereby oxygen can be blown into the person if necessary.

3 shows a person 6 with a sensor 3, which determines the physiological functions of the person 6, for example the oxygen content in the blood. This data from the sensor 3 is transmitted to a recording device 8 for further evaluation. If necessary, oxygen can be blown into the person via 2 nozzles.

4 shows a device according to the invention for the targeted supply of oxygen to the nostril 7 of a person. For this purpose, the nozzle can be moved in accordance with the directions of movement 12, with the nozzle 11 being aligned specifically to the nostril 7 in accordance with the data from a nozzle 9. The nozzle 11 is supplied with oxygen from a line 14, the line 14 being attached to the person's shirt (6) with a clip 13, for example.

5 shows a special embodiment of the invention with a wheel 15 that is movable and on which the nozzle 11 is arranged. The wheel 15 can rotate and thereby bring the nozzle 11 into a suitable position in order to be able to supply oxygen to a person 6.

6 shows a drone 17, on which a nozzle 11 is arranged for supplying oxygen to an exhausted person 6, so that this person 6 in particular does not fall asleep or fall into unconsciousness. The drone 17 also carries an oxygen tank 19, which supplies the nozzle 11 with oxygen. In addition, a sensor 10 is arranged on the drone 17 in order to be able to supply the oxygen to the person 6 precisely.

7 shows a section of a driver's cab 23 with a rear-view mirror 21 and a steering wheel 20, with sensors 3 being arranged within the driver's cab 23 to determine the oxygen content in the driver's cab 23 to measure. Sensors 3 can be arranged in particular at the height of a driver's nose. A sensor 3 for measuring the oxygen content can be arranged in the sky, on a rear-view mirror or on the steering wheel 20. The steering wheel 20 can also have a tactile surface 22 that can determine whether the driver is exhausted based on a driver's finger placement. For this purpose, in particular, the degree of sweat secretion can be determined.

It should be noted that the term “comprise” does not exclude additional elements or steps, just as the terms “a” and “an” do not exclude multiple elements and steps.

The reference numerals used are merely for the purpose of increasing clarity and are in no way intended to be limiting, the scope of the invention being reflected in the claims.
