Abstract

In a patient bed for an operating table, comprising a plurality of bed portions (18, 32, 70, 72), of which a middle portion (18) is designed for connection to the supporting column of the operating table and which are coupled releasably to one another via interfaces (30, 68), at least one bed portion (70, 72) being adjustable in relation to an adjacent bed portion (32) in the region of an interface (68), the middle portion (18) of the bed (16) is connectable at at least one of its ends, via a first interface (30), to the one end of an intermediate portion (32) which is connectable at its other end, via a second interface (68), to a further bed portion (70, 72), the first interface (30) having two first coupling elements (34, 36) which engage positively one in the other for a rigid connection and which have transmission elements coming into contact with one another during interengagement and intended for the transmission of signals and/or energy, and the second interface (68) comprising two second coupling elements which are intended for positive engagement with one another and of which the second coupling element (74) arranged on the intermediate portion (32) can be adjusted, by means of an actuating drive arranged on the intermediate portion, about an axis parallel to the bed plane and perpendicular to the bed longitudinal direction.

Claims

1. A patient bed for an operating table, comprising a plurality of bed portions, of which a middle portion is designed for connection to the supporting column of the operating table and which are coupled releasably to one another via interfaces, at least one bed portion being adjustable in relation to an adjacent bed portion in the region of an interface, wherein the middle portion of the bed is connectable at at least one of its ends, via a first interface, to the one end of an intermediate portion which is connectable at its other end, via a second interface, to a further bed portion, in that the first interface has two first coupling elements which engage positively one in the other for a rigid connection and which have transmission elements coming into contact with one another during interengagement and intended for the transmission of signals and/or energy, and in that the second interface comprises two second coupling elements which are intended for positive engagement with one another and of which the second coupling element arranged on the intermediate portion can be adjusted, by means of an actuating drive arranged on the intermediate portion, about an axis parallel to the bed plane and perpendicular to the bed longitudinal direction.

2. The patient bed according to claim 1, wherein, in the case of both interfaces, in each case one of the coupling elements is provided with at least one hook and the other coupling element with at least one complementary hook receptacle.

3. The patient bed according to claim 1 wherein the coupling elements of the interfaces which are in engagement with one another are interlockable by means of a positive interlock.

4. The patient bed according to claim 1, wherein the coupling elements of the two interfaces are not mutually compatible.

5. The patient bed according to claim 1, wherein at least one further bed portion, which can be coupled to the intermediate portion via a second interface, is coupleable at its other end, via a third interface, to an accessory part.

6. The patient bed according to claim 5, wherein the third interface comprises third coupling elements engaging positively one in the other.

7. The patient bed according to claim 6, wherein the third coupling elements are designed such that the accessory-side third coupling element is compatible with the first coupling element arranged on the middle portion, and in that the third coupling element arranged on the further bed portion is incompatible with the first coupling element arranged on the intermediate portion.

8. The patient bed according to claim 1, wherein the actuating drive comprises a threaded worm driven by a motor and a worm wheel driven by the threaded worm, and in that the adjustable second coupling element is connected fixedly in terms of rotation to the worm wheel.

9. The patient bed according to claim 1, wherein the middle portion comprises two segments which are pivotable relative to one another about a pivot axis directed transversely to the longitudinal direction of the bed.
