Abstract

A ventilator system has at least one ventilator unit and a number of docking stations is described. Each docking station is adapted to receive the ventilator unit and comprises a communication interface adapted to be connected to a matching interface on the ventilator unit when the ventilator unit is docked in the docking station. The docking stations are arranged at different treatment sites, and the ventilator unit can be moved between different docking stations when necessary without interrupting the treatment of a patient connected to the ventilator unit. The same ventilator unit can be used throughout a complete treatment of a patient without any need of disconnecting the patient during transports, etc.

Claims

1. A ventilator system comprising:

at least one ventilator unit, said at least one ventilator unit having a ventilator communication interface, said at least one ventilator unit being adapted for connection to a patient for treatment of a patient and containing ventilator unit components operable to provide prescribed breathing assistance to a patient;

a plurality of docking stations each having at least one supply source, selected from the group consisting of gas supply sources and power supply sources, at least some supply sources respectively at different docking stations being of different types and having different operating conditions associated therewith, each of said docking stations being adapted for connection to said at least one ventilator unit and comprising a control unit containing information and programming for operation of said at least one ventilator at the docking station comprising the control unit dependent on the operating conditions associated with the at least one supply source at that docking station, said at least one ventilator unit when connected to that docking station, each docking station having a docking station communication interface connected to the control unit at that docking station and mateable with said ventilator communication interface, said ventilator communication interface and said docking station communication interface, when mated, said at least one ventilator unit supplying said information and programming to said ventilation unit components for operating said at least one ventilator unit to provide said prescribed breathing assistance using the operating conditions at the docking station to which the at least one ventilator unit is connected; and

said docking stations being disposed at different treatment sites, spaced from each other, and said at least one ventilator unit being mobile between said docking stations without interruption of treatment of a patient connected to said at least one ventilator unit.

2. A ventilator system as claimed in claim 1 wherein said ventilator communication interface and said docking station communication interface comprise means for exchanging electronic signals.

3. A ventilator system as claimed in claim 2 further comprising a common network connected to each of said docking stations, and wherein said electronic signals contain information identifying said at least one ventilator unit for allowing identification of a current location of said at least one ventilator unit in said common network.

4. A ventilator system as claimed in claim 3 comprising a plurality of ventilator units, each of said ventilator units having unique information identifying that ventilator unit contained in the electronic signals, allowing a location of each of said plurality of ventilator units to be identified in said common network.

5. A ventilador system as claimed in claim 1 wherein said ventilator communication interface and said docking station communication interface comprise means for receiving exhaled gas from said at least one ventilator unit for evacuation of said exhaled gas through said doking station.

6. A ventilator system as claimed in claim 1 wherein each of said docking stations comprise means for connecting said docking station to any source of gas.

7. A ventilator system as claimed in claim 1 wherein each of said docking stations comprises means for connecting said docking station to a source of gas selected from the group consisting of a fixed hospital gas supply system, gas cylinders, gas compressors, and fans.

8. A ventilator system as claimed in claim 1 wherein said ventilator communication interface and said docking station communication interface comprise means for supplying power from said docking station to said ventilator unit.
