Description

Field of the Invention

The present invention pertains generally to emergency systems and more particularly to a personal emergency-reporting system.

Background of the Invention

A vehicle emergency radio system, which comprises a positioning system, a crash sensor, and an emergency call transmitter as its essential elements, has been known from DE 43 21 416 A1. It is ensured with this system that an emergency call signal is sent by radio together with the instantaneously stored position data in the case of an accident, a rescue operation is possible after reception and forwarding to a rescue coordination center.

Summary and Objects of the Present Invention

The primary object of the present invention is to provide a personal, automatic emergency-reporting system, which makes possible a rapid, specific rescue operation to a person whose health is acutely at risk.

According to the invention, a personal emergency-reporting system is provided including a portable patient data unit which contains a satellite-supported Global Positioning System (GPS) receiver means. The GPS receiver means is connected to a patient data acquisition and evaluation unit via a computer and control unit. The computer and control unit are connected to an emergency call transmitter, which sends patient data and position information to an emergency call receiver in the case of an emergency.

The personal emergency-reporting system is preferably provided with the positioning system, the patient data acquisition and evaluation unit, the computer and control unit, and the emergency call transmitter arranged in a standard housing.

The patient data unit preferably has a reading and writing device for magnetic or optical data storage media, which is connected to the computer and control unit. The data storage medium with the patient data is preferably used to record the emergency operation for clinical treatment or for medical evaluation. The patient data unit preferably additionally has acoustic and/or optical signal transmitters, which are activated in the case of an emergency.

One essential advantage of the system according to the present invention is that the individual data of the patient in question, including personal history and dates of treatment, are stored in a suitable data storage medium during the accident and are thus available for recording the rescue operation, for the further treatment in the hospital, and for additional documentation and further evaluation purposes, e.g., the billing for services. In a preferred embodiment, the patient data unit, to be carried on the patients body, is arranged in a compact design in a standard housing.

The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and specific objects attained by its uses, reference is made to the accompanying drawings and descriptive matter in which a preferred embodiment of the invention are illustrated.

Brief Description of the Drawings

In the drawings:

The only FIGURE is a schematic view that shows an exemplary embodiment according to the invention.

Description of the Preferred Embodiment

Referring to the drawings in particular, the core of the system according to the present invention is a compact patient data unit 1, which can be carried by the patient, preferably directly on the body, and which preferably has the following functional elements in a standard, compact housing 13:

The satellite-supported Global Positioning System (GPS) 2 is in radio connection with a satellite 8 via an antenna 7 in order to determine the patient's exact position during the phase of operation of the patient data unit 1 after an emergency situation of the patient occurs.

The position data are polled by the computer and control unit 3 from the positioning system 2 as soon as an emergency of the patient has been determined on the basis of the current patient data determined by the patient data acquisition and evaluation unit 4. In another preferred embodiment of the present invention, the patient data unit 1 has an additional, acoustic and/or optical signal transmitter 11, 12, which warns the patient correspondingly when an emergency occurs. As an alternative or in addition, provisions may also be made for the patient to trigger an alarm via the computer and control unit 3 by actively actuating a switching element 14 of the patient data unit 1.

At any rate, via suitable sensors and patient data pickups 9, the patient data acquisition and evaluation unit 4 determines important medical parameters of the patient, e.g., the heart rate, blood pressure and additionally, depending on the patient's medical history, special additional parameters, such as cardiac arrhythmias, which may be of great significance for the occurrence of an emergency and the emergency operation itself, at predetermined time intervals. In addition, the patient data unit 1 has a data storage medium reading and writing device 5 to ensure the current storage and availability of all relevant data of the patient. The data storage medium is preferably an optical data storage medium of high storage capacity, which as an individual patient data file may contain both the patient's current status and his history as well as health insurance data. The data storage medium reading and writing device 5 communicates with the computer and storage unit 3. An emergency call is sent automatically if the computer and evaluation unit 3 now determines a change in the status of the patient that is relevant for the definition of an emergency by comparing stored, preset limit values with the current parameters of the patient, which are determined by means of sensors via patient data pickups 9.

The computer and control unit 3 sends a release signal in this case to the emergency call transmitter 6, which sends an emergency call signal by radio via the antenna 7 together with the patient's position data being polled instantaneously by the positioning system 2 and with patient data selected by the computer and control unit 3. The emergency radio signal with the position data and the selected patient data is received directly by the antenna of the nearest rescue coordination center/emergency call center 10. As an alternative, it would also be possible to use the nearest base station of a corresponding mobile radio telephone system.

By means of the position and patient data transmitted, a rapid and specific rescue operation is possible for the individual patient based on his personal indications, e.g., by the deployment of medical specialists and by providing special drugs and devices in the ambulance, emergency physician's car or rescue helicopter to be used.

After the site of the accidence has been reached, the data storage medium with the patient data can be removed from the patient data unit 1 and be introduced into a suitable, corresponding reading and writing unit in the rescue unit in order to record, document and evaluate the emergency treatment during the rescue operation as well as for the subsequent treatments in the hospital or during the rehabilitation. The data desired for the further use of the patient data unit 1 on the patient can subsequently be provided specifically on the data storage medium; these data may include, e.g., critical limit values for relevant parameters of the patient, so that the further use of the patient data unit 1 is thus made possible for an emergency operation by means of the individual patient data storage medium. The patient data unit 1 is preferably operated by rechargeable batteries as a self-contained unit.

While a specific embodiment of the invention has been shown and described in detail to illustrate the application of the principles of the invention, it will be understood that the invention may be embodied otherwise without departing from such principles.
