Abstract

A blood vessel on a person's suitable extremities is used to measure blood oxygen content through a sensor if the person goes under in the water. Information on this gathered by an analyzer device triggers an alarm if oxygen content level exceeds a preset threshold. A device can be integrated in an armband for children or in a wristwatch for adults during swimming.

Description

Die vorliegende Erfindung bezieht sich auf eine Einrichtung zur Rettung ertrinkender Personen.The present invention relates to a device for rescue drowning people.

Bekannt sind Rettungshilfen, wie beispielsweise Rettungsringe, Schwimmwesten etc., die am Körper getragen werden und so ein Abtauchen einer Person verhindern sollen.Rescue aids such as lifebuoys are known Life jackets etc. that are worn on the body and so on Prevent a person from diving.

Aufgabe der vorliegenden Erfindung ist es, rechtzeitig zu signalisieren, dass eine Person in Gefahr ist, zu ertrinken. Dies ist sinnvoll und notwendig, vor allem in Schwimmbädern und Badeseen, wo Rettungskräfte vor Ort sind, wo aber oft zu spät bemerkt wird, dass eine Person sich unter Wasser befindet. Hier muss festgestellt werden, ob eine Person nur beim normalen Schwimmen oder Tauchen unter Wasser ist, oder ob bereits die Gefahr des Ertrinkens besteht.The object of the present invention is to signal in good time that that a person is in danger of drowning. This makes sense and necessary, especially in swimming pools and bathing lakes, where Rescue workers are on site, but where it is often noticed too late that a Person is under water. Here it must be determined whether a Person is only under normal swimming or diving, or whether there is already a risk of drowning.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Sauerstoffgehalt des Blutes gemessen und ggf. ein Alarm ausgelöst wird. Da bei abgetauchten Personen kein Sauerstoff mehr über die Lunge aufgenommen werden kann, sinkt der Gehalt im Blut ab. Es gibt einfache und gleichzeitig für den vorliegenden Fall gut geeignete Verfahren, den Sauerstoffgehalt zu bestimmen, nämlich die Bestimmung an einem geeigneten Blutgefäss einer Körperextremität, beispielsweise am Finger oder am Ohr. Eine Auswerteeinheit vergleicht den ermittelten Sauerstoffgehalt mit einem abgespeicherten Minimalwert und löst bei Unterschreitung einen Alarm aus. Sensor und Auswerteeinheit sind mobil und werden am Körper getragen. Die Auswerteeinheit könnte beispielsweise in eine Armbanduhr, ein Armband, in den Schlüssel für die Badekabine oder in die Badebekleidung integriert sein. Der Sensor kann entweder fester Bestandteil der Auswerteeinheit sein oder er ist ein abgesetztes Teil und ist beispielsweise als Fingerring ausgestaltet. This object is achieved in that the Oxygen content of the blood is measured and an alarm is triggered if necessary. Since submerged persons no longer have oxygen in their lungs can be absorbed, the blood content drops. There are simple ones and at the same time a method that is well suited to the present To determine oxygen content, namely the determination on a suitable blood vessels of a body extremity, for example on the finger or on the ear. An evaluation unit compares the determined one Oxygen content with a stored minimum value and dissolves Falling below an alarm. The sensor and evaluation unit are mobile and are worn on the body. The evaluation unit could for example in a wrist watch, a bracelet, in the key for the Bathing cabin or be integrated into the swimwear. The sensor can either be an integral part of the evaluation unit or it is a stepped part and is designed for example as a finger ring.  

Günstig ist eine solche Einrichtung auch, um Personen in trüben Gewässern oder unter Eis aufzufinden. Hierfür kann der Alarm als akustisches Signal realisiert sein, da dessen Ausbreitung unter Wasser möglich ist und so Personen geortet werden können. Natürlich kann auch ein Lichtsignal (z. B. Lichtblitze) oder ein von einem Peilempfänger zu empfangendes Funksignal verwendet werden.Such a facility is also beneficial to people in cloudy conditions Found in water or under ice. The alarm can be used as acoustic signal can be realized, since its spread under water is possible and so people can be located. Of course you can too a light signal (e.g. flashes of light) or one from a DF receiver receiving radio signal can be used.

Für Schwimmbadbesucher könnte die Einrichtung beispielsweise am Schlüssel für der Kleiderschrank befestigt oder darin integriert sein. Für Kinder- und Erwachsenen-Schlüssel wären geeignete Sauerstoff-Werte fest voreingestellt. Sobald ein Badegast den Minimal-Sauerstoffwert unterschreitet, würde ein Alarm ausgelöst. Hier wäre es vorteilhaft, einen Funkalarm zu verwenden und einen geeigneten Empfänger im Schwimmbecken zu integrieren, der die Alarmsignale empfangen und dann die Aufsichtspersonen alarmieren kann. Auch eine Ortung abgetauchter Personen im Schwimmbecken ist so möglich.For swimming pool visitors, the facility could, for example, on Keys for the wardrobe attached or integrated. For Child and adult keys would be suitable oxygen values fixed preset. As soon as a bather reaches the minimum oxygen level an alarm would be triggered. Here it would be beneficial to have one Use radio alarm and a suitable receiver in the Integrate swimming pool that receives the alarm signals and can then alert the supervisors. Also a location Submerged people in the swimming pool is possible.
