KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die "Überwachung von Wundverbänden u. dgl. erfordert große Aufmerksamkeit seitens des Wärterpersonal's, ohne daß eine volle Sicherheit z. B. gegen das Verbluten von Patienten gegeben ist. So kann z. B. eine Blutung bei einem schlafenden Patienten eintreten, welche erst dann bemerkt wird, wenn ein Eingreifen des Arztes bzw. Wärters vielleicht zu spät ist.The "monitoring of wound dressings and the like requires a great deal of attention of the guard's staff, without a full security z. B. against bleeding to death Patient is given. So z. B. bleeding occurs in a sleeping patient, which is only noticed when the doctor or guard may intervene is too late.
ίο Zur Vermeidung dieser Übelstände soll eine elektrische Alarmvorrichtung eingeschaltet werden, welche ein Signal auslöst, sobald der Verband infolge einer eintretenden Blutung feucht wird. Es sind allerdings schon elekirische Kontaktvorrichtungen zum Anzeigen von Durchnässungen (infolge von Harnentleerungen) bekannt. Bei diesen wird das Schließen des elektrischen Kontaktes dadurch bewirkt, daß eine die Elektroden trennende Schicht durch die hinzutretende Flüssigkeit aufgelöst oder erweicht wird, so daß eine direkte Berührung der Elektroden zustande kommt. Eine derartige Vorrichtung kann nicht einfach auf einen Wundverband übertragen werden. Denn das zwischen die Elektroden tretende Blut würde die Isolierschicht nicht auflösen oder erweichen, sondern dort gerinnen. Außerdem muß das Auslösen des Signals schon, wenn eben die Wunde zu bluten beginnt, erfolgen, nicht erst, nachdem schon ein größerer Blutverlust eingetreten ist. Dieses Ziel wird bei der vorliegenden Erfindung dadurch erreicht, daß zwischen die beiden dem Verbände beigefügten Elektroden eine Isolierschicht gebracht wird, welche schon durch das Hinzutreten weniger Bluts-ίο To avoid these evils one should electrical alarm device can be switched on, which triggers a signal as soon as the Bandage becomes damp as a result of bleeding. However, they are already electrical Contact devices to indicate waterlogging (as a result of urination) known. With these the closing of the electrical contact is thereby causes a layer separating the electrodes through the liquid to be added is dissolved or softened so that the electrodes come into direct contact comes. Such a device cannot simply be transferred to a wound dressing will. Because the blood passing between the electrodes would not dissolve or soften the insulating layer, but there curdle. In addition, the signal must be triggered when the wound starts to bleed, not after there has already been a significant loss of blood. This aim is achieved with the present invention achieved by placing between the two electrodes attached to the dressing an insulating layer is applied, which by the addition of less blood
tropfen genügend leitend wird, um einen schwachen Relaisstrom zu schließen, welcher dann seinerseits einen stärkeren Strom auslöst, der ein akustisches oder optisches Signal bewirkt.drop becomes conductive enough to close a weak relay current, which then in turn triggers a stronger current that emits an acoustic or visual signal causes.
In der Zeichnung zeigt Fig. 1 eine Anwendungsart der neuen Vorrichtung an einem Oberarm, während die Fig. 2 bis 6 verschiedene Formen der Elektroden veranschaulichen. In the drawing, Fig. 1 shows a type of application of the new device on a Upper arm, while Figs. 2 to 6 illustrate different shapes of the electrodes.
Wie aus Fig. 1 ersichtlich, ist die Wunde am Oberarm mit einer Kompresse α ο. dgl. überdeckt und auf diese die Elektrode b gelegt. Diese Elektrode ist derart ausgebildet, daß durch sie j ede Feuchtigkeit (Blut, Sekrete usw.) durchtreten kann. Sie ist daher zweckmäßig mit Löchern oder Schlitzen e versehen oder siebartig ausgebildet. Auf der Elektrode b ist eine Schicht Watte, eine Mullbinde o. dgl. c aufgelegt, welche von der Elektrode d überdeckt ist. Diese Auflagen sind dann mit einer Binde o. dgl. in bekannter ■ AVeise umwickelt.As can be seen from Fig. 1, the wound on the upper arm is α ο with a compress. Like. Covered and placed on this the electrode b . This electrode is designed in such a way that any moisture (blood, secretions, etc.) can pass through it. It is therefore expediently provided with holes or slots e or designed like a sieve. A layer of cotton wool, a gauze bandage or the like c is placed on the electrode b , which is covered by the electrode d. These pads are then wrapped with a bandage or the like in a known manner.
Die Elektroden sind mit einem Stromkreis unter Zwischenschaltung eines Relais verbunden. In diesen Stromkreis sind akustische oder optische Signale, Klappenkästen o. dgl. eingebaut, durch deren Ansprechen sofort zu erkennen ist, daß ein Stromdurchgang statt-' findet. Dieser kann aber nur dann erfolgen, wenn die zwischen den Elektroden b und d liegende Isolierschicht c leitend wird, d. h. wenn die Mull- oder Watteschicht Blut oder Wundsekrete von der Kompresse α ansaugt, was durch die Öffnungen der Elektrode b geschieht. The electrodes are connected to a circuit with the interposition of a relay. Acoustic or optical signals, flap boxes or the like are built into this circuit, and by responding to them it can be seen immediately that a current is flowing through. However, this can only take place when the insulating layer c lying between the electrodes b and d becomes conductive, ie when the gauze or cotton wool layer sucks in blood or wound secretions from the compress α , which happens through the openings in the electrode b .
Da eine beliebige Anzahl dieser Kontrollvorrichtungen an eine Leitung angeschlossen werden kann, ist eine gleichzeitige Kontrolle von vielen Verbänden möglich. Spricht ein Signal an und ist keine lebensgefährdende Blutung aufgetreten, sondern lediglich der Verband durchsecerniert, so bedeutet dies den Zeitpunkt des Verbandwechsels oder einer Neubedeckung des alten Verbandes.As any number of these control devices are connected to one line can be, a simultaneous control of many associations is possible. Speaks Signal on and no life-threatening bleeding has occurred, just the Association secreted through, this means the time of the dressing change or one New coverage of the old association.
