Abstract

The invention relates to a device for recording and/or monitoring medical data, particularly data pertaining to the cardiovascular condition and to the blood properties of an individual having, for example, cardiovascular disorders or diabetes. Said device comprises at least one measuring sensor (3, 3′, 23), in particular, an car sensor for detecting the cardiovascular condition of the individual (1) and comprises a logic controller for determining irregularities in the data recorded by the measuring sensor. The device also comprises a transmitting-receiving device (5) for voice and/or data in order to dial up at least one third party (9) and to transmit data thereto. Finally, the device comprises a locating system module by means of which the location of the individual is transmitted to the third party.

name and address of the person

information regarding the treating physician or regarding the treating medically trained persons

family members to be notified

information regarding the insurance protection.

10. Configuration as claimed in claim 9, characterized in that the memory module is a so-called SIM card (Subscriber Identity Module), which card is disposed in the transmitting and receiving device, in order to associate it with the person.

11. Configuration, in particular as claimed in one of claims 1 to 10, characterized in that the measuring sensor comprises

an arrangement (23) to be placed on an ear, which comprises one part each which can be placed at least on one place of the ear lobe and/or the external ear, wherein
