Abstract

A housing holder for a medical monitor, which can be a cardiotocograph, includes a housing reception unit provided with several recesses. The monitor housing of the medical monitor has a plurality of protrusions provided on the back wall thereof, and arranged such that they are adapted to be inserted into the recesses of the housing reception unit. At least one of the protrusions has a stationary, downwardly directed projection for engagement with the side of the housing reception unit facing away from the monitor housing, the engagement being effected in the area of the respective recess. At least one additional protrusion is equipped with a spring-loaded snap member for engagement with the side of the housing reception unit facing away from the monitor housing, the engagement being effected in the area of another of the recesses.

Claims

1. A medical apparatus comprising:

a housing reception unit having at least two recesses;

a medical monitor having a monitor housing with at least two protrusions which are provided on a back wall thereof and which are arranged such that they are adapted to be inserted into the recesses of the housing reception unit;

at least one of said protrusions having a stationary, essentially downwardly directed projection for engagement with a side of the housing reception unit facing away from the monitor housing, the engagement being effected in the area of at least one the recesses;

at least one additional of said protrusions being equipped with a snap means for engagement with the side of the housing reception unit facing away from the monitor housing, such engagement being effected in the area of another one of the recesses, the snap means including a downwardly directed hook which is provided with a ramp surface for an edge of a complementary recess of the housing reception unit, the ramp surface being arranged such that it extends at an angle to a plane of the back wall of the monitor housing, the snap means further including a spring which is arranged between the hook and the monitor housing and by means of which said hook is spring loaded in the downward direction;

the back wall of the monitor housing defining between its upper area and its lower area a receding step extending in the direction of an inner side of the monitor housing;

the housing reception unit defining between its upper area and its lower area a projecting step which extends in the direction of the monitor housing and which is located below the receding step in the back wall of the monitor housing in spaced relationship therewith; and

an actuating member connected to the snap means in an area of said snap means located within the monitor housing and extending through an opening in the step in the back wall of the monitor housing, said actuating member being arranged for unlocking the snap means against its spring loading.

2. A medical apparatus according to claim 1 wherein the snap means is arranged such that it is movable in a lateral direction in a sliding guide rail which is formed on the inner side of the back wall of the monitor housing.

3. A medical apparatus according to claim 1 wherein the depth of the steps is at least 1.2 cm, and the distance between the steps is at least 6 cm.

4. A medical apparatus according to claim 3 wherein the depth of the steps is at least 1.5 cm and the distance between the steps is at least 8.5 cm.

5. A medical apparatus according to claim 1 wherein the protrusions are defined by foot members of the monitor housing.

6. A medical apparatus according to claim 1 wherein the housing reception unit is constructed as a wall-mounted holder for holding the monitor housing in an essentially vertical position.

7. A medical apparatus according to claim 1 wherein the housing reception unit is constructed as an angular support holder for supporting the monitor housing in an inclined position relative to a horizontal base of the angular support holder.

8. A medical apparatus according to claim 1 wherein the housing reception unit is provided with supporting surfaces arranged behind said recesses with respect to the monitor housing.

9. A medical apparatus according to claim 1 wherein the medical monitor is a cardiotocograph.

10. A medical apparatus according to claim 1 further comprising an additional snap means which is spatially separated from the snap means mentioned above, both the additional snap means and the snap means being arranged such that they can be individually operated.
