Abstract

A medical monitor (1) comprises a recess (6) in its bottom side. A lateral wall (9) of this recess (6) is oriented in the same direction as the front panel (2) of medical monitor (1) and carries connectors or jacks. If the medical monitor is operated in a vertical position, its rear panel becomes its top panel. The rear panel does not comprise any connectors, and the connectors at lateral wall (9) as well as patient connectors (3a, 3b, 3c, 4) are oriented downwards. Therefore, the monitor is safe against sprayed or spilled fluids even if operated in vertical position.

Claims

1. A casing for an instrument, comprising:

a front panel characterized by a first normal vector, said first normal vector being defined as a vector oriented in a direction which is normal to a surface of said front panel;

a bottom side, attached to said front panel, comprising a recess, said recess comprising at least three lateral walls at least one of which is substantially parallel to and located opposite said front panel, wherein an outside surface of said at least one of said lateral walls is characterized by a second normal vector that is defined as a vector oriented in a direction which is normal to said outside surface, said second normal vector being oriented in substantially the same direction as said first normal vector of the front panel, and said at least one of said lateral walls comprises at least one cable connector;

means for hanging the casing substantially vertically such that said first and second normal vectors are oriented substantially in a downward direction; and

a shoulder extending around said casing in a direction parallel to said front panel and including a side wall a part of which adjoins said recess and forms said at least one of said lateral walls.

2. A casing as recited in claim 1, further comprising a second recess arranged between and connecting said at least one of said lateral walls and a rear panel.

3. A casing as recited in claim 1, wherein said front panel comprises means for connecting a patient cable.

4. A casing as recited in claim 1, further comprising a power inlet jack.

5. A casing as recited in claim 1, wherein said bottom side comprises, outside said recess, at least three base support plugs.

6. A casing as recited in claim 1 or 5, wherein said bottom side comprises a second recess arranged between and connecting said at least one of said lateral walls and a rear panel.

7. A casing as recited in claim 6, wherein said second recess comprises a strain relieving device.

8. A casing as recited in claim 7, wherein said strain relieving device comprises at least a tongue protruding from a side wall of said second recess.

9. A casing as recited in claim 8, wherein said tongue is made of elastic material.

10. A casing as recited in claim 8, wherein said tongue is pivoted in said casing and further comprising spring means for forcing said tongue to a closed position.

11. A medical monitor, comprising:

a casing containing electronic circuitry for receiving, processing, displaying and recording signals representative of physiological parameters of a subject, said casing comprising;

a front panel characterized by a first normal vector, said first normal vector being defined as a vector oriented in a direction which is normal to a surface of said front panel;

a bottom side, attached to said front panel, comprising a recess, said recess comprising at least three lateral walls at least one of which is substantially parallel to and located opposite said front panel, wherein an outside surface of said at least one of said lateral walls is characterized by a second normal vector that is defined as a vector oriented in a direction which is normal to said outside surface, said second normal vector being oriented in substantially the same direction as said first normal vector of the front panel, and said at least one of said lateral walls comprises at least one jack or connector for connection of an interface cable; and

means for hanging the casing substantially vertically such that said first and second normal vectors are oriented substantially in a downward direction; and

a shoulder extending around said casing in a direction parallel to said front panel and including a side wall a part of which adjoins said recess and forms said at least one of said lateral walls.

12. A medical monitor as recited in claim 11, further comprising a second recess arranged between and connecting said at least one of said lateral walls and a rear panel.

13. A medical monitor as recited in claim 11, wherein said front panel comprises means for connecting a patient cable.

14. A medical monitor as recited in claim 11, wherein said bottom side comprises a second recess arranged between and connecting said at least one of said lateral walls and a rear panel.

15. A medical monitor as recited in claim 14, wherein said second recess comprises a strain relieving device.

16. A medical monitor as recited in claim 15, wherein said strain relieving device comprises at least a tongue protruding from a side wall of said second recess.

17. A medical monitor as recited in claim 16, wherein said tongue is made of elastic material.

18. A medical monitor as recited in claim 16, wherein said tongue is pivoted in said casing and further comprising spring means for forcing said tongue to a closed position.
