Display and control device for medical equipment
A display and control device for medical equipment, comprising several identically configured display/control units, which are located on a base unit. The base unit is equipped with a bus, to which the display/control units and components of the medical equipment are connected. The base unit comprises connection devices, which are used to connect the display/control units to the bus. Once a display/control unit has been connected, a configuration unit transmits configuration data to the display/control unit and only then defines which function the display/control unit is to fulfill. This permits defective display/control units to be simply replaced. The construction of the display/control units is likewise simple and not susceptible to malfunctions.
1. A heart lung machine, comprising:
a plurality of pumps; and
a display and control device operably connected to the plurality of pumps, the display and control device including:
at least one display/control unit including:
a display device having a plurality of activatable pixels,
a display activation device which activates the pixels of the display device on the basis of data supplied,
a transparent input device disposed on a surface of the display device that is to face an observer,
an input evaluation device which evaluates inputs made via the transparent input device, and
a unit connector with which the display activation device and the input evaluation device are connected and by which the at least one display/control unit can be connected to an electric bus, and
a base unit including:
the electric bus for the communication of units connected thereto,
a plurality of connector devices at which the at least one display/control unit can be connected to the electric bus via the unit connector, and
a configuration device which is connected with the electric bus and which, after connection of one of the at least one display/control unit to the electric bus, transmits configuration data determining display contents and input areas of the one of the at least one display/control unit via the electric bus,
wherein the configuration device transmits the configuration data for two or more functions of fill levels of a reservoir, air bubbles in a fluid, temperature of the fluid entering the reservoir, and temperature of the fluid exiting the reservoir, in a sequence of the two or more functions and the one of the at least one display/control unit receives a function in the sequence of the two or more functions based on an order of connection of the one of the at least one display/control unit to the base unit.
2. The heart lung machine according to claim 1 , wherein multiple areas to display contents and to receive inputs are logically defined in the display device of the at least one display/control unit.
3. The heart lung machine according to claim 2 , wherein the multiple areas are combinable to form a connected area.
4. The heart lung machine according to claim 1 , wherein the at least one display/control unit includes multiple display/control devices that are constructed identically.
5. The heart lung machine according to claim 1 , wherein the at least one display/control unit is fixed to the base unit by way of a connection between the unit connector and a connector device of the plurality of connector devices.
6. The heart lung machine according to claim 5 , wherein the at least one display/control unit is fixed on the base unit via additional fixing elements.
7. The heart lung machine according to claim 1 , wherein data for displaying digits, numbers and map pixels are stored in the display activation device of the at least one display/control unit.
8. The heart lung machine according to claim 1 , wherein the at least one display/control unit and the configuration device are arranged such that data for display contents can be transmitted to the at least one display/control unit by the configuration device and stored in the at least one display/control unit.
9. The heart lung machine according to claim 8 , wherein the at least one display/control unit informs the configuration device of which data for display contents are stored in the display activation device.
10. The heart lung machine according to claim 1 , wherein the at least one display/control unit includes a bus communication device via which the display activation device and the input evaluation device are connected to the bus.
11. The heart lung machine according to claim 1 , wherein no further control elements are provided.
12. The heart lung machine according to claim 1 , wherein apart from an on/off switch, no further control elements are provided.
