Device for assisting a first aider with a cardiopulmonary resuscitation

Abstract

The invention relates to a device for assisting a first aider with a cardiopulmonary resuscitation of a person suffering cardiac arrest, comprising a transport housing (1), in which a sensor apparatus (4) and two adhesive electrodes (2), which are or can be connected to the sensor apparatus (4), can be stowed. The sensor apparatus (4) allows data to be acquired while the first-aid measures for resuscitation are performed. The sensor apparatus (4) comprises an adhesive (5) for attachment to the chest of the patient (3). The chest compressions, i.e. depth of compression and compression frequency, can be detected by means of a motion sensor. An interface for data transfer allows wireless communication with a mobile terminal (6). Furthermore, the sensor apparatus (4) contains a high-voltage store so that, after connection to the adhesive electrodes (2), a single defibrillation shock can be delivered.

Claims

1. An apparatus for supporting a first aider in a cardiopulmonary resuscitation, comprising a sensor device, two adhesive electrodes connectable or connected with the sensor device and a largely flat transport housing in which the sensor device and the two adhesive electrodes are storable, wherein the sensor device comprises a top side that contacts a hand of the first aider when the sensor device is used as intended, and a bottom side opposite the top side, a storage for electrical energy, a microprocessor and a high-voltage storage with terminals for the adhesive electrodes, an activation apparatus for connecting at least the microprocessor and the high-voltage storage to the storage for electrical energy, a movement sensor and an interface for sending and/or receiving data and/or commands, characterized in that the transport housing is rigid and has geometric external dimensions of at most 10 cm10 cm3 cm, the bottom side of the sensor device has an adhesive substance arranged on a surface area for fastening the sensor device on the chest of a patient or a training mannequin, the adhesive electrodes comprised kinked folds, by which the adhesive electrodes are folded during storage in the transport housing, the storage for electrical energy and the high-voltage storage are designed in such a way that exactly only one defibrillation shock can be delivered, wherein residual energy remaining in a battery after delivery of the shock is only sufficient to keep the sensors, the microprocessor and the interface working for about 30 minutes.

2. The apparatus according to claim 1, characterized in that at least one surface area of the top side of the sensor device comprises an adhesive coating or an adhesive material.

3. The apparatus according to claim 1, characterized in that the interface is wireless.

4. The apparatus according to claim 1, characterized in that the storage for electrical energy is rechargeable, wherein the sensor device has an inductive charging interface for an inductive charging device.

5. The apparatus according to claim 1, characterized in that the motion sensor is an acceleration sensor.

6. The apparatus according to claim 1, characterized in that the adhesive substance is an adhesive bandage, the adhesive surface of which is covered with a removable protective film.

7. The apparatus according to claim 1, characterized in that it has a positioning tool connected to the sensor device for the exact positioning of the sensor device on the sternum.

8. The apparatus according to claim 7, characterized in that the positioning tool is a measuring standard that can be folded-out or pulled-out of the sensor device.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) To this end, shows in a schematic representation

(2) FIG. 1: an embodiment of the apparatus in plan view; and

(3) FIG. 2: an application of the apparatus on the patient.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(4) According to FIG. 1, the apparatus comprises the two-part transport housing 1, which is designed here as a waterproof container. In the same the two adhesive electrodes 2 with the cables 8 and the sensor device 4 are situated. In FIG. 1, the positioning tool 7, which has already been pulled out of the sensor device 4, is shown. On the back of the sensor device 4, the adhesive 5 is applied, by means of which the sensor device 4 can be attached to the chest.

(5) According to FIG. 2, when an emergency occurs, the sensor device 4 and the adhesive electrodes 2 are removed from the transport housing 1. The adhesive electrodes 2 are attached to the chest of the patient 3 and connected to the sensor device 4 by means of the cables 8. The sensor device 4 (here an embodiment without a positioning tool) is switched on by actuating the switch 9, whereby the high-voltage storage (not shown) is also charged, and is subsequently attached to the chest of the patient 3.

(6) The mobile terminal 6, here a smartphone, communicates by means of a wireless interface (here according to the WLAN 802.11ax standard) with the sensor device 4. Software, started on the mobile terminal 6 guides the first aider (not shown), whereby itwhen the corresponding indication applyafter the first aider has been informedautomatically triggers a single defibrillation shock.
