Safety system for use in medical tables

The system according to any one of the preceding claims, wherein the restrictions in operation of the operating table comprise restrictions for a plurality of different patient weight ranges.

The system according to any one of the preceding claims, furthermore comprising an input unit (650) for entering the weight of a patient placed on the operating table and/or an interface for receiving pieces of electronic patient weight information from outside the system.

The system according to any one of the preceding claims, wherein at least one of the display unit (607) and the input unit (650) is provided by a remote control or a display screen that is physically separated from the patient support surface (600).

The system according to any one of the preceding claims, wherein the restrictions on the operation of the operating table comprise one or more of the following restrictions:

• restrictions on the use of secondary support surface sections (602-605), restrictions on the configuration of secondary support surface sections (602-605), restrictions on the selection of axes around which movement of the secondary support surface sections (602-605) is possible, restrictions on the range within which a secondary support surface section (602-605) can be moved around an axis, restrictions on the speed at which a secondary support surface section (602-605) can be moved around an axis, restrictions on the maximum weight of the patient, restrictions on the longitudinal displacement of the patient support surface (600), restrictions on the Trendelenburg tilting of the patient support surface (600), restrictions on the lateral tilting of the patient support surface (600), restrictions on the height adjustment of the patient support surface (600), restrictions on the extension of the rollers of the operating table, restrictions on the motorized transport of the operating table, and/or restrictions on the lateral displacement of the patient support surface.

The system according to any one of the preceding claims, wherein the evaluation unit (606) is designed such that it receives pieces of weight information for a patient before the patient is located on the patient support surface (600) and that it uses the pieces of weight information in determining movement restrictions for the patient support surface (600).

The system according to any one of the preceding claims, wherein the display unit (607) is provided on a remote control, a display screen on a wall, or a display screen on a ceiling arm, and

• wherein the restrictions on the operation of the operating table comprise restrictions on the longitudinal displacement of the patient support surface (600) and/or restrictions on the Trendelenburg tilting of the patient support surface (600).

The system according to any one of the preceding claims, wherein the patient support surface (600) comprises a main support surface section (601) and one or more secondary support surface sections (602-605), and the configuration of the patient support surface (600) is the configuration in which the secondary support surface sections are connected to one another and to the main support surface section.

The system according to any one of the preceding claims, wherein the evaluation unit (606) determines the restrictions on the operation of the operating table and the restrictions are displayed on the display unit (607) when the operating table and/or the patient support surface (600) are in a rest state in which the operating table and/or the patient support surface (600) are not moving and when no signal or command to move the operating table and/or the patient support surface (600) is pending.

The system according to any one of the preceding claims, wherein the patient support surface (600) comprises a main support surface section (601) and one or more secondary support surface sections (602-605), and by identifying the patient support surface (600) it is known which secondary support surface sections (602-605) are connected to the main support surface section (601).

The system according to any one of the preceding claims, wherein the patient support surface (600) comprises a main support surface section (601) and one or more secondary support surface sections (602-605), and the evaluation unit (606) identifies at least which secondary support surface sections (602-605) are connected to the main support surface section (601), and wherein the evaluation unit (606) uses this identification to determine and display restrictions on the future movement of the patient support surface (600) after the patient has been placed on the patient support surface (600).

An operating table system comprising an operating table (500) having an operating table column (510) and a system according to any one of the preceding claims, wherein the patient support surface (600) is fastened on the operating table column (510).

A method for determining and displaying restrictions on the operation of an operating table, wherein

• the operating table has a patient support surface (600) fastened on an operating table column,
• restrictions on the operation of the operating table are determined based on at least the identification and/or configuration of the patient support surface (600) and the restrictions are displayed by a display unit (607) before the patient is placed on the patient support surface (600).
