Abstract

Apparatus for checking anaesthesia and ventilation devices, in the form of a test lung, comprising a lung sac, elastically deformable lobes, an inlet nozzle and adjustment means for adjusting the simulation parameters, the test lung being in the form of a compact unit and permitting the simulation of different lung types by adjustment of the lung parameters.

Claims (77)

1. A lung simulator comprising:

a first lobe panel, said first lobe panel being elastically deformable, said first lobe panel having a fixed first longitudinal end;

a sac disposed under said first lobe panel;

an inlet nozzle in fluid communication with said sac;

said first lobe panel having a second longitudinal end opposite to said first longitudinal end;

a second longitudinal end region of said first lobe panel proximate to said second longitudinal end;

an adjustable slide externally disposed over said second longitudinal end region of said first lobe panel, said adjustable slide including a transverse member extending across the width of said lobe panel;

a first group of catch openings located in said second longitudinal end region of said first lobe panel; and,

at least one slide projection configured to engage said catch openings.

2. A lung simulator as claimed in claim 1 , further comprising:

a housing supporting said inlet nozzle; and,

an adjustable control valve threaded into a bore in said housing, said adjustable control valve selectively controlling gas leakage from said inlet nozzle.

3. A lung simulator as claimed in claim 1 , further comprising:

a housing configured to rotatably support said inlet nozzle;

a lock configured to fix said inlet nozzle at one of plural selectable rotational locations relative to said housing; and,

a variable inlet passage for nozzle flow, said variable inlet passage having flow cross-sectional area determined by a selected rotational location of said inlet nozzle relative to said housing.

4. The lung simulator as claimed in claim 1 , wherein:

said first lobe panel is made of plastic.

5. The lung simulator as claimed in claim 4 , wherein:

said first lobe panel includes reinforced fiber composite.

6. The lung simulator as claimed in claim 1 , wherein:

said first lobe panel is made of spring steel.

7. A lung simulator as claimed in claim 1 , further comprising:

a second lobe panel, said second lobe panel having a respective fixed first longitudinal end, said second lobe panel having a respective second longitudinal end opposite to said first longitudinal end of said second panel.

8. The lung simulator as claimed in claim 7 , wherein:

said respective first longitudinal end of said first lobe panel is integrally connected to said second lobe panel's respective first longitudinal end.

9. A lung simulator as claimed in claim 7 , further comprising:

said adjustable slide includes a second transverse member extending across the width of said second lobe panel.

10. A lung simulator as claimed in claim 7 , further comprising:

said second lobe panel having a respective second longitudinal end region proximate to its respective second longitudinal end;

a second group of catch openings located in said respective second longitudinal end region of said second lobe panel.

11. A lung simulator comprising:

a first lobe panel, said first lobe panel being elastically deformable, said first lobe panel having a fixed first longitudinal end;

a sac disposed under said first lobe panel;

an inlet nozzle connected to said sac;

said first lobe panel having a second longitudinal end opposite to said first longitudinal end;

a second longitudinal end region of said first lobe panel proximate to said second longitudinal end;

an adjustable slide externally disposed at said second longitudinal end region of said first lobe panel;

a first group of catch openings located in said second longitudinal end region of said first lobe panel;

at least one slide projection configured to engage said catch openings;

a housing configured to rotatably support said inlet nozzle;

a lock configured to fix said inlet nozzle at one of plural selectable rotational locations relative to said housing;

a variable inlet passage for nozzle flow, said variable inlet passage having flow cross-sectional area determined by a selected rotational location of said inlet nozzle relative to said housing; and,

an adjustable control valve threaded into a bore in said housing, said adjustable control valve selectively controlling gas leakage from said inlet nozzle.

12. A lung simulator as claimed in claim 11 , further comprising:

a second lobe panel, said second lobe panel having a respective fixed first longitudinal end, said second lobe panel having a respective second longitudinal end opposite to said first longitudinal end of said second panel.

13. The lung simulator as claimed in claim 12 , wherein:

said respective first longitudinal end of said first lobe panel is integrally connected to said second lobe panel's respective first longitudinal end.

14. A lung simulator as claimed in claim 12 , further comprising:

said adjustable slide is externally disposed over said second longitudinal end region of said first lobe panel, said adjustable slide including a first transverse member extending across the width of said first lobe panel.

15. A lung simulator as claimed in claim 14 , further comprising:

said adjustable slide includes a second transverse member extending across the width of said second lobe panel.

16. A lung simulator as claimed in claim 12 , further comprising:

said second lobe panel having a respective second longitudinal end region proximate to its respective second longitudinal end;

a second group of catch openings located in said respective second longitudinal end region of said second lobe panel.

17. A lung simulator as claimed in claim 12 , further comprising:

a fixing screw connecting the respective second longitudinal ends of said first and second lobes.

18. A lung simulator as claimed in claim 11 , further comprising:

a rotary hand knob configured for manual rotation of said adjustable control valve.

19. A lung simulator as claimed in claim 11 , further comprising:

a scale configured to indicate the rotational position of said inlet nozzle, said scale mounted on an end face of said housing.

20. A lung simulator comprising:

a first lobe panel, said first lobe panel being elastically deformable, said first lobe panel having a fixed first longitudinal end;

said first lobe panel having a second longitudinal end opposite to said first longitudinal end;

a second longitudinal end region of said first lobe panel proximate to said second longitudinal end;

a second lobe panel, said second lobe panel having a respective fixed first longitudinal end, said second lobe panel having a respective second longitudinal end opposite to said first longitudinal end of said second lobe panel, said second lobe panel having a respective second longitudinal end region proximate to its respective second longitudinal end;

said respective first longitudinal end of said first lobe panel is integrally connected to said second lobe panel's respective first longitudinal end;

an adjustable slide clamp externally disposed over said second longitudinal end region of said lobe panels, said adjustable slide clamp including a first transverse member extending across the width of said first lobe panel, said adjustable slide clamp including a second transverse member extending across the width of said second lobe panel;

catch openings located in said respective second longitudinal end regions of said lobe panels;

slide clamp projections configured to engage said catch openings;
