Treatment device and the, in particular automatic, selecting in the memory device of the medical treatment device in connection with the information for identification of the patient stored medical data of the patient for their transfer from the

Storage device of the medical treatment device on the first and / or the second external electronic

Storage medium.

As used herein, the term "patient identification information" refers to data such as personal data of the patient, which may be selected from a patient's name, surname, first name, date of birth, place of birth, address, occupation, and the like Number, eg one

Patient number in a treatment clinic, a hospital and the like. The details for the identification of the patient need not be complete. They merely need to be suitable for e.g. be able to identify the medical record of the patient in question from records of other patients in a database.

Entering the information for the identification of the patient in the medical treatment device or in a

Memory or a storage and / or reading device thereof can be done manually.

The input can be electronically transmitted by e.g. Scanning a code, such as a barcode, from a carrier, such as a barcode. a paper printout of the patient's admission or a

Patient bracelet and the like, take place. The input can be done by voice input. To enter such data, the medical

Treatment device have suitable input devices or be functionally coupled with such devices.

The selection of the medical data of the patient on the basis of the entered information for the identification of the patient can be done automatically, e.g. by means of a suitable, provided and configured device.

Such suitable devices may be provided according to or in the medical treatment device.

The selection of the patient's medical data can be done by the medical treatment device checking whether there is already data for that patient in it

are stored. The examination can take place via a comparison of personal data of the patient, such as first and last name, if necessary, in addition the date of birth of the patient, patient number and the like. Once an entry has been found, a user (e.g., the physician, nurses, and the like) may be informed that the patient is already known and that data / settings may be accepted or transmitted to the first or second external electronic storage medium. '

In a further embodiment, the method also includes transmitting data for identifying the patient from the storage device of the medical device

Treatment device on the first or the second external electronic storage medium. The data for the identification of the patient may be data which, with the aid of the medical alone

Treatment device are not changeable.

The transfer of the data for identifying the patient to the second external electronic storage medium takes place in an embodiment of the method according to the invention for the first time or initially. In other words, the data for identifying the patient are transferred to a second external electronic storage medium which does not already have this data, possibly even completely blank, e.g. a blank, is. In some embodiments of the invention thereby the second external electronic

Storage medium thus assigned to the patient for the first time.

A still unused second external electronic

Storage medium may thus be initiated using the medical treatment device. This can advantageously be associated with further effort accessing, for example, a central

Database can be avoided.

The automatic deletion of the medical data may e.g. then provided or desired, if the. Data from the penultimate treatment (irrespective of when it took place), relative to the current one

Treatment, are no longer relevant. The predetermined one

Event, for which the automatic deletion of the data recorded as penultimate data should take place, can therefore, for example, accordingly be determined as the number of interim, ie since storage of the data to be deleted treatments.

One basis for this may be that the medical records of a particular patient are not within a certain time limit in the memory of the medical

Treatment device have been updated. Furthermore, it may be desired or intended to delete the oldest entries. For example, if a patient has not been treated at the medical treatment facility for some time, his data may be deleted from their storage facility. In this way, the storage capacity of the

Storage device of the medical treatment device advantageously further lowered.

The data can be completely deleted. Parts of the data or data record can be deleted.

According to the invention, an "automatic deletion" can mean that neither the deletion nor the triggering of the deletion process is an action or an action of the patient or of the patient

Operator of medical treatment device

Transfer of data - directly from the medical

Treatment device or by means of the medical

Treatment device or means integrated therewith - on a first or a second external electronic storage medium (such as a personal

electronic patient card) of a patient.

Since the patient's external electronic storage medium may advantageously have a complete database of the patient at the time of the last treatment, the patient may also appropriate the next medical treatment (e.g., dialysis treatment) at another

medical treatment device (e.g., dialysis machine) and is not so advantageous. always bound to the same machine. This can also advantageously include the fact that the patient can be treated at a different location in another dialysis clinic, for example, and can always have all the data necessary for this.
