Description

The present invention relates to a medical device having at least one sensor for detecting at least one parameter of the respiratory gas, an operating device for specifying settings, a control unit which is connected to a memory unit and a first computer program product for implementing the settings taking into account the specification, and a second computer program product, which regulates a data transfer from and to the control unit via at least one interface, via the at least one interface a mutual exchange of data between the device and external storage media and / or devices takes place and also parameters can be exchanged and parameters and / or the configuration of the device can be loaded from external storage media and / or devices.

If a doctor or reseller needs to check / change the settings of a ventilator, he or she currently has to physically have the device in front of them. If the ventilation settings for a patient must be monitored or adjusted as continuously as possible, the patient must either stay in the hospital or consult a doctor regularly.

Likewise, if the software / firmware needs updating, the patient must come to the doctor, reseller, or hospital to have the update installed.

Even with a device replacement, for example due to a defect, currently the new device must be set back to the patient. For this, the settings must be made by the doctor or specialist dealer.

Applicants' SOMNOcomfort or SOMNOvent CR ventilators, for example, use an RS485 serial interface to read respiratory data from the ventilator and, if necessary, visualize it on a PC. In order to make a setting of the ventilation parameters, however, the doctor must make a change to the settings on the device.

This increases the cost of healthcare and patients who either have to stay in the hospital or need to see a doctor very often are significantly reduced in their daily lives.

There is a need to simplify or save the described processes in order to relieve the physician or specialist dealer and thus save costs.

From the DE 10 2007 039 004 A1 is a medical device with at least one sensor for detecting at least one parameter of a breathing gas known. An operating device is used to specify settings. In addition, a control unit is used to implement settings as well as to coordinate a data transfer.

Other devices and methods for configuring medical devices are incorporated into the US 2007/0055799 A1 . DE 100 165 580 A1 . DE 10 2004 042 797 A1 as well as the EP 2 017 586 A1 described.

The object of the present invention is to provide a ventilator which allows a data transfer between the ventilator and external storage media and / or devices, in which the configuration of the ventilator can be easily replaced.

The object is achieved by the features of the device claim 1 and by the features of the method claim 21 of the present application.

This saves working time, as the device or accessories can be read directly out of the carrying bag, without opening, removing, connecting power and data line.

The invention is not only interesting for accessories and sensors, but also for therapy and diagnostic equipment, eg. B. in the application for simplified logistics in warehousing. Device type and serial number can be read out without contact. The advantage over barcodes is that devices are also recognized in the bag. This is to simplify processes and avoid confusion in a bag swap.

RFID is just one conceivable embodiment. Others would be Z-Wave or Zigbee. In each of the radio transmission modes used in the invention little energy is needed to send information, so that either no power supply is necessary or a mobile power supply (battery, battery, button cell, capacitor, fuel cell) is sufficient for a very long period of time.
