Abstract

The invention relates to an arrangement for inducing a state of anaesthesia in a living creature and maintaining the creature in that state by administering to the said creature an infused volume of liquid anaesthesia-inducing medication per unit of time, preferably during the use of one or more lung ventilation unit(s)s and one or more infusion unit(s).

The arrangement comprises a basic unit (102) with control function software (600a′–600r′) and one or more modular unit(s) (30′, 30, 30″) containing hardware for the control functions. When a modular unit (30′) co-acts with the basic unit (102), it (30′) activates the control functions stored in the basic unit (102).

5. An arrangement according to claim 4, wherein said unit capable of affecting therapeutic criteria comprises one or more computer unit.

6. An arrangement according to claim 1, wherein at least one of said modular units cooperate with the basic unit in order to achieve selected basic unit functions, and wherein software is distributed between the basic unit and one or more modular unit.

7. An arrangement according to claim 1, wherein at least one of said modular units comprises function-related hardware, related to one or more criteria.

8. An arrangement according to claim 1, wherein said function-related computer software, is configured for operating with said diagnostic or therapeutic criteria.

9. An arrangement, according to claim 8, wherein said function-related software stored in the basic unit can be updated without the modular unit initiating the update.

10. An arrangement according to claim 1, wherein at least one of said modular units is configured with hardware and/or software related to a single function.

11. An arrangement according to claim 1, wherein at least one of said modular units is configured with hardware and/or software related to a plurality of selected functions.

12. An arrangement according to claim 1, wherein a plurality of said modular units is configured with hardware and/or software related to a single function.

13. An arrangement according to claim 1, wherein at least one of said modular units cooperates with said basic unit to provide sensing of one or more function-related criteria.

14. An arrangement according to claim 1, wherein function-related software stored in the basic unit is configured for making a distinction between therapeutic criteria and diagnostic criteria when therapeutic modular units and/or diagnostic modular units are attached to the basic unit.

15. An arrangement according to claim 1, wherein one or more first criteria, related to one or more diagnostic units, and one or more second criteria, related to one or more therapeutic units, can be displayed on a screen, one or more of said first criteria are selected for screen display as momentary values, and one or more of said first criteria are selected for screen display of chronological variations in the criterion.

16. An arrangement according to claim 15, wherein one or more of said second criteria are selected for screen display as momentary values, and one or more of said second criteria are selected for screen display of chronological variation in the criterion.

17. An arrangement according to claim 15, wherein time axes for certain criteria, selected for display as the criterion'"'"'s chronological variation are coordinated and stacked atop one another.

18. An arrangement according to claim 15, wherein a sensor signals for some criteria are delayed.

19. An arrangement according to claim 15, momentary values for one or more criteria related to one or more diagnostic units, and/or momentary values for one or more criteria related to one or more therapeutic units, can be stored in memories for display, when needed, as the criterion'"'"'s chronological variation.

20. An arrangement according to claim 15, wherein said momentary values can be stored time-related in memories so chronological curves can be displayed, thereby reproducing a curve'"'"'s trend, or alternately displaying variations in a compressed time format.

21. An arrangement according to claim 1, wherein said basic unit housing has a front, and said housing recess is in said front of said basic unit housing.
