Description

The invention relates to a patient support device, a movable medical device, a method for moving a patient support device, and a computer program product.

In the context of medical imaging methods and / or medical examinations and / or treatments of an examination object, for example an animal and / or human patient, the examination object is often arranged on a patient support device, in particular lying down. In this case, the patient support device often comprises a patient support plate for the arrangement of the examination subject, as well as a support element which stably supports the patient support plate.

Depending on the area of application, many different types of patient support devices have been developed, each of which is particularly suitable for at least one application. For example, patient positioning devices are often used for medical imaging methods which have materials that are as artifact-free and / or transparent to imaging as possible and at the same time mechanically stable, for example carbon fiber plates. Furthermore, many applications of the patient support device in a medical environment often require a high degree of mobility and / or flexibility, in particular for the arrangement of the examination subject. For this purpose, patient support devices comprising a plurality of sub-plates of the patient support plate that are movable relative to one another are known. Movable and / or height-adjustable and / or pivotable and / or tiltable patient support devices are also known.

The known patient support devices can often only be driven under to a limited extent. Often the support element is arranged in a stationary manner with respect to the patient support plate and / or in a stationary manner with respect to the floor of the room and can thus become an obstacle for medical operating personnel and / or a medical device which is moved below the patient support plate. As a result, there is a disadvantageous risk of injury to the medical operating personnel. Furthermore, a collision can occur between a medical device, for example a medical imaging device and / or a medical irradiation device, and the support element of the patient support device.

The invention is therefore based on the object of specifying a patient support device which enables collision-free driving under the patient support device.

The object is achieved according to the invention by a patient support device, a movable medical device, a method for moving a patient support device, and a computer program product according to the independent claims. Advantageous embodiments with expedient developments are the subject of the subclaims.

According to this, it is provided that the patient support device comprises at least one patient support plate and at least one support element. In this case, the at least one support element comprises a first movement device which is designed to translate and rotate the at least one support element in a plane that is horizontal, in particular with respect to a room underground. Furthermore, the at least one support element further comprises a processing unit which is designed to control the at least one support element. Furthermore, the processing unit is designed to receive an approach signal. The processing unit controls a movement of the at least one support element in such a way that the at least one support element stably supports the at least one patient support plate and executes an evasive movement by means of the first movement device along the horizontal plane as a function of the approach signal.

The patient support device can comprise one and / or more patient support plates. The at least one patient support plate can advantageously be pivotable and / or tiltable with respect to a horizontal plane, in particular a floor space. Furthermore, the plurality of patient support plates can be arranged such that they can pivot with respect to one another. For this purpose, the multiple patient positioning plates can be held by a patient positioning plate carrier, in particular such that they can be moved relative to one another. The at least one patient support plate advantageously has an imaging-transparent and / or radiolucent and / or artifact-free material, for example a carbon fiber and / or a plastic and / or a ceramic. The at least one patient support plate is advantageously inherently stable and / or dimensionally stable.

Furthermore, the at least one support element can be designed to stably support the at least one patient support plate, in particular to carry it. The stable support of the patient support plate, in particular with an examination object arranged thereon, describes a tilt-proof and / or low-vibration support of the patient support plate by the at least one support element. In this case, the examination object can include, for example, a human and / or animal patient and / or a phantom. Further For example, the at least one support element can in particular also be designed for stable support of an at least one patient support plate pivoted to the horizontal plane.

Furthermore, the at least one support element can comprise a plate sensor element which is designed to detect a positioning of the at least one patient support plate. The detected positioning of the at least one patient support plate can advantageously include information on the position and / or alignment of the at least one patient support plate with respect to the horizontal plane and / or the at least one support element. Furthermore, the detected positioning of the at least one patient support plate can include information on the arrangement of a plurality of patient support plates, in particular pivoted relative to one another.

Furthermore, the at least one support element advantageously comprises the first movement device. The first movement device can advantageously comprise a movement element, for example a chassis and / or a motor drive element, for example an electric motor. The chassis can for example include at least one, in particular omnidirectional, wheel. Furthermore, the support element can be arranged movably along a guide device, for example a rail, by means of the movement element. The at least one support element can advantageously be moved along the horizontal plane by means of the first movement device. The movement of the at least one support element along the horizontal plane can advantageously include a translation and / or rotation of the at least one support element.

Furthermore, the at least one support element can be mechanically and / or electromagnetically coupled to the at least one patient support plate so as to be movable at least at times. This enables a movement of the at least one support element by means of the first movement device along the horizontal plane, in particular independently of a movement of the at least one patient support plate. The at least one support element can advantageously be coupled to the at least one patient support plate in such a way that pivoting and / or movement of the at least one patient support plate with respect to the at least one support element is made possible.

The first movement device can advantageously comprise at least one sensor element for detecting a movement and / or a movement state and / or a positioning of the at least one support element. The at least one sensor element can be designed, for example, as a wheel encoder and / or an optical sensor and / or an electromagnetic sensor. In this case, the state of motion of the at least one support element can advantageously include information on a speed of movement and / or direction of movement. Furthermore, the positioning of the at least one support element can advantageously include information on a position and / or orientation of the at least one support element, in particular with regard to a reference point in space and / or with regard to a medical device and / or with regard to the at least one patient support plate.

Furthermore, the at least one support element can advantageously have at least one, in particular movably arranged, mass element that enables stable support of the at least one patient support plate without tilting even when the support element is arranged on an outer side of the at least one patient support plate. Here, an, in particular momentary, position of the at least one mass element relative to a center of gravity of the at least one support element and / or the at least one patient support plate can advantageously be taken into account during a movement and / or alignment of the at least one support element. Furthermore, the at least one mass element can be arranged movably in such a way that the center of gravity of the at least one support element can advantageously be adapted by moving the at least one mass element.

Furthermore, stable support of the at least one patient support plate by the at least one support element can be ensured by an advantageous shape of the at least one support element, for example C-shaped and / or L-shaped, and / or locking of the first movement device. For example, the first movement device can be mechanically and / or electromagnetically locked in a stationary manner to the room underground and / or the guide device via at least one locking element. Furthermore, the at least one support element having an advantageous shape can be rotated within the horizontal plane in such a way that the at least one patient support plate is supported in a particularly stable manner by the at least one support element.

Furthermore, the at least one support element further comprises a processing unit which is designed to control the at least one support element, in particular the first movement device of the support element. Furthermore, the processing unit of the at least one support element is designed to receive the approach signal. The approach signal can advantageously provide information on a change in position and / or movement of a physical object and / or an operating personnel in a, in particular predetermined, spatial environment of the at least one support element, in particular along a direction of movement towards the at least one support element.

Receiving the approach signal can in particular include capturing and / or reading out a computer-readable data memory and / or receiving from a data storage unit.

Furthermore, the processing unit can be designed to receive patient positioning information. The patient positioning information can advantageously include information on the arrangement and / or storage and / or alignment of the examination object arranged on the at least one patient support plate.

Furthermore, the processing unit can be designed to receive the positioning of the at least one patient support plate. Receiving the patient positioning information and / or the positioning of the at least one patient support plate can in particular include detecting and / or reading out a computer-readable data memory and / or receiving from a data storage unit. In particular, the patient positioning information can be provided by a medical device, in particular a medical imaging device, and / or a camera system, for example a mono camera and / or stereo camera.

Advantageously, the processing unit can control the movement of the at least one support element in such a way that the at least one support element stably supports the at least one patient support plate and, in particular at the same time, performs an evasive movement by means of the first movement device along the horizontal plane as a function of the approach signal received. In this case, the evasive movement can in particular describe a movement of the at least one support element along the horizontal plane, which is essentially not in the opposite direction to a direction of movement encompassed by the approach signal. In this way, it can be achieved that the at least one support element, in particular autonomously, based on the approach signal, evades an operator and / or object approaching the at least one support element in the immediate vicinity and at the same time the at least one patient support plate stable supports. Furthermore, the movement of the at least one support element, in particular the first movement device, can be controlled by the processing unit in such a way that the at least one support element and / or the at least one patient support plate executes an evasive movement along the horizontal plane as a function of the approach signal.

In this case, the control of the movement of the at least one support element, in particular the control of the first movement device, advantageously takes place both on the basis of the approach signal and while taking into account limitations with regard to a possible radius of movement of the at least one support element. For example, a possible radius of movement of the at least one support element can be limited by the outer sides of the at least one patient support plate. Furthermore, the control of the movement of the at least one support element, in particular the control of the movement device, can also take place taking into account a positioning of the at least one patient support plate relative to the at least one support element and / or a positioning of an examination object arranged on the at least one patient support plate. This makes it possible to ensure that the at least one support element continues to support the at least one patient support plate in a stable manner even in the event of an evasive movement. In this case, when controlling the movement of the at least one support element as a function of the approach signal, the support of the at least one patient support plate is prioritized before the evasive movement.

Advantageously, a collision-free drive under the patient support device can thereby be made possible.

In a further advantageous embodiment of the proposed patient support device, the patient support device can furthermore comprise at least one proximity sensor. The at least one proximity sensor can advantageously be designed to provide the proximity signal to the processing unit in accordance with a detected approach of an operating personnel, in particular at least a part of the body of the operating personnel, and / or an objective object to the at least one support element. The at least one proximity sensor can advantageously comprise an optical sensor, for example an infrared sensor and / or a camera system, in particular comprising a 3D camera, and / or an electromagnetic sensor and / or an ultrasonic sensor. The at least one proximity sensor is advantageously used to monitor a spatial environment, in particular the entire spatial environment A region below the at least one patient support plate, the at least one support element, is formed with regard to an approach of an operating personnel and / or an objective object to the at least one support element. The object in question can, for example, be a medical device, in particular an anesthesia device and / or an EKG device, and / or a device, for example a tripod and / or a bucket and / or a trolley, and / or a medical imaging device, for example a medical x-ray device, in particular a medical C-arm x-ray device, and / or an ultrasound device and / or a computed tomography system (CT) and / or a magnetic resonance device (MRT).

The approach signal can advantageously include information on the approaching physical object and / or operating personnel, for example size information and / or shape information. Furthermore, the approach signal can also include information on a change in position and / or movement, in particular a direction of movement and / or speed of movement, of the approaching objective object and / or operating personnel.

Furthermore, providing the approach signal to the processing unit of the at least one support element can in particular include storage on a computer-readable storage medium and / or transmission to the processing unit.

Furthermore, the at least one proximity sensor can be arranged on the at least one patient support plate and / or in the room, in particular at a distance from the at least one support element.

In this way, particularly efficient and directed control of the movement of the at least one support element can advantageously take place as a function of the approach signal.

In a further advantageous embodiment of the proposed patient support device, the processing unit can control the movement of the at least one support element in such a way that a positioning of an examination object arranged on the at least one patient support plate remains unchanged.

The positioning of the examination object arranged on the at least one patient support plate can advantageously include information on the arrangement and / or storage and / or alignment of the examination object, in particular with respect to the at least one patient support plate.

Advantageously, the at least one support element can be mechanically and / or electromagnetically coupled to the at least one patient support plate in such a way that a movement of the at least one support element towards the at least one patient support plate in the same direction as the movement of the at least one support element with respect to a floor space takes place.

Furthermore, the at least one patient support plate can have at least one guide element, for example a rail, which is designed to enable a movement of the at least one support element along the horizontal plane, in particular also with an arrangement of the at least one patient support plate pivoted to the horizontal plane. The at least one support element can advantageously be mechanically and / or electromagnetically coupled to the guide element of the at least one patient support plate. Furthermore, several patient support plates, in particular pivotable with respect to one another, can each have one and / or a common guide element. As a result, a pose and / or positioning of the plurality of patient support plates and the examination object arranged thereon can advantageously remain unchanged when the at least one support element is moved.

The first movement device of the at least one support element can advantageously be designed to move the at least one support element with respect to the floor of the room and the at least one patient support plate along the horizontal plane. Thus, the at least one support element can be moved by means of the first movement device with respect to the floor of the room and the at least one patient support plate along the horizontal plane. In this case, the at least one patient support plate can advantageously be moved in the opposite direction by means of the first movement device for moving the at least one support element with respect to the floor of the room.

If the at least one support element, as described above, comprises a plate sensor element, the movement of the at least one support element can advantageously be detected by the processing unit both with respect to the floor of the room and with respect to the at least one patient support plate. Furthermore, the processing unit can receive patient positioning information, for example from a medical imaging device and / or an optical sensor, in particular a camera system. The patient positioning information, in particular instantaneous, can thereby be used for particularly precise control of the movement of the at least one support element for maintaining the positioning of the examination object and simultaneous evasive movement are taken into account as a function of the approach signal.

By maintaining a positioning of the examination object arranged on the at least one patient support plate, movement artifacts can advantageously be avoided. Furthermore, the collision-free ability to drive under the patient support device can advantageously be made possible.

In a further advantageous embodiment of the proposed patient support device, the at least one support element can comprise a second movement device which is designed to adjust the height of the support element, in particular the at least one patient support plate coupled to it. In this case, the evasive movement of the at least one support element by means of the first and the second movement device can take place along the horizontal plane and / or in a vertical direction, in particular with respect to the floor of the room, as a function of the approach signal.

Furthermore, the second movement device can have a hydraulic cylinder and / or a rack and pinion drive and / or an electromagnetic drive. As a result, the movement of the at least one support element, in particular the first and the second movement device, can be controlled by the processing unit in such a way that both the at least one support element and the at least one patient support plate are dependent on the approach signal along the horizontal plane and / or the vertical direction be moved. As a result, the at least one support element and / or the at least one patient support plate with the examination object arranged thereon can perform an evasive movement as a function of the approach signal along the horizontal plane and / or the vertical direction.

In particular in the case of an arrangement of the at least one patient support plate that is pivoted with respect to the horizontal plane and / or the at least one support element, an evasive movement of the at least one support element along a vertical direction may be necessary. The at least one support element can advantageously be moved by means of the first and the second movement device along the horizontal plane and the vertical direction in such a way that a positioning and / or pose of the pivoted arrangement of the at least one patient support plate is maintained. The movement of the first and the second movement device can advantageously take place in a coordinated manner and / or at the same time.

In a further advantageous embodiment of the proposed patient positioning device, the approach signal can be provided by a medical device. In this case, the approach signal can advantageously include, in particular momentary, positioning information of the medical device with respect to the patient positioning device. The medical device can be used, for example, as a medical imaging device, for example a medical x-ray device, in particular a C-arm x-ray device, and / or a computed tomography system (CT) and / or magnetic resonance system (MRT) and / or ultrasound device, and / or a medical device for monitoring the The examination subject, in particular an EKG device, and / or an anesthesia device and / or an irradiation device can be designed. Furthermore, the medical device can, in particular, be movable with respect to the patient support device.

The medical device can advantageously provide the approach signal to the processing unit of the at least one support element. In this case, the positioning information of the medical device can preferably include information on the, in particular current, position and / or orientation and / or pose and / or direction of movement and / or speed of movement of the medical device with respect to the patient positioning device. Furthermore, the proximity signal can advantageously include information on an extent, in particular a height and / or width, of the medical device.

In particular if the medical device comprises a robot and / or robot arm, positioning information including information on the pose of the robot and / or robot arm can be particularly helpful for controlling the evasive movement of the at least one support element.

The medical device can advantageously have a positioning detection element which is designed to detect the, in particular momentary, positioning of the medical device in the room and / or with respect to the patient positioning device. In particular, the positioning detection element can comprise a wheel encoder and / or an optical sensor, for example a camera system, and / or an electromagnetic sensor and / or an ultrasonic sensor. Furthermore, the positioning detection element can advantageously be used to generate and / or provide the approach signal to the Processing unit of the at least one support element be formed.

Furthermore, providing the proximity signal to the processing unit of the at least one support element can include, in particular, storage on a computer-readable storage medium and / or, in particular wireless, transmission from the medical device to the processing unit of the at least one support element.

This enables particularly precise control of the movement, in particular the evasive movement, of the at least one support element as a function of the approach signal.

Furthermore, the processing unit of the at least one support element can be designed to receive multiple proximity signals from one medical device in each case. The movement of the at least one support element can advantageously be controlled as a function of the multiple proximity signals.

In a further advantageous embodiment of the proposed patient positioning device, the approach signal can furthermore include a planned movement path of the medical device. The processing unit can control the movement of the at least one support element in such a way that there is no collision between the at least one support element and the medical device on the planned movement path.

In particular, if the medical device is designed as a movable medical imaging device and / or a movable irradiation device, the medical device can also be designed to carry out a medical imaging method and / or to irradiate an examination object arranged on the patient support device. In this case, the medical device can be moved along a, in particular predetermined, movement path for carrying out the medical imaging method and / or the irradiation. For example, the medical device can be moved along a patient axis of the examination subject and / or around the examination subject. An unimpeded, in particular collision-free, movement of the medical device with respect to the patient support device can be advantageous. The movement of the at least one support element can advantageously be controlled, in particular navigated, based on the approach signal in such a way that there is no collision between the at least one support element and the medical device on the planned movement path.

The planned movement path can in particular include a future temporal sequence of spatial positions and / or orientations and / or poses of the medical device with respect to the patient positioning device. In particular, the planned movement path can be two-dimensional and / or three-dimensional. The movement, in particular the evasive movement, of the at least one support element can advantageously be controlled taking into account the future timing of the planned movement path. For example, the at least one support element can be moved away from the planned movement path in order to avoid the medical device. The movement of the at least one support element can in particular take place within a spatial limitation, in particular through the at least one patient support plate. Furthermore, the at least one support element can be moved as a function of the approach signal, in particular the planned movement path of the medical device, in such a way that it evades the medical device on the planned movement path and stably supports the at least one patient support plate. Furthermore, the planned movement path can include a chronological sequence of patient positions of the examination object arranged on the at least one patient support plate. The movement of the at least one support element can advantageously be controlled as a function of the planned movement path in such a way that the at least one support element stably supports the at least one patient support plate, performs an evasive movement in relation to the medical device and enables the chronological sequence of patient positioning.

Advantageously, by providing the proximity signal from the medical device, more precise positioning information of the medical device can be received by the processing unit of the at least one support element. This enables a particularly efficient and directed control of the movement of the at least one support element, in particular to avoid the medical device. Furthermore, the proximity signal provided by the medical device can be used to move the at least one support element to avoid the medical device, in particular the planned movement path, independently of a proximity sensor. In this way, in particular, rapid movements of the medical device can be taken into account at an early stage in the control of the movement of the at least one support element. Especially with a medical device that can be moved by means of a robot, in particular a robot arm, a reliable detection of the medical device by a proximity sensor can be made more difficult. By controlling the movement of the at least one support element as a function of the planned movement path provided, in particular including the temporal sequence of the spatial positions and / or poses of the robot arm, a particularly reliable and precise evasive movement of the at least one support element can be made possible.

In a further advantageous embodiment of the proposed patient positioning device, the approach signal can include an intervention workflow on an examination object arranged on the at least one patient positioning plate. The processing unit can control the movement of the at least one support element in such a way that the examination object is accessible to operating personnel in accordance with the intervention workflow and / or maximum stability is ensured against the action of force in accordance with the intervention workflow in at least one section of the at least one patient support plate.

The intervention workflow can in particular include a time sequence of workflow parameters and / or operating parameters of a medical device and / or operating parameters of a medical instrument and / or recording parameters of a medical imaging device. Furthermore, the intervention workflow can include a chronological sequence of patient positioning. For example, a workflow parameter can include positioning information, for example a spatial position and / or alignment, for the optimal arrangement of operating personnel, in particular medical operating personnel, with respect to the object to be examined. Furthermore, the workflow parameter can include at least one spatial position and / or an examination area in the examination area, which must be accessible to operating personnel and / or a medical device and / or a medical instrument.

Advantageously, the processing unit can control the movement of the at least one support element as a function of the intervention workflow in such a way that the examination object arranged on the patient support device, in particular the at least one patient support plate, is accessible to operating personnel and / or a medical device and / or a medical instrument according to the intervention workflow is.

In particular if the patient support device has several patient support plates, an advantageous arrangement, in particular pivoting, of the patient support plates relative to one another can enable access to the examination subject from several sides. The movement of the at least one support element, depending on the intervention workflow, enables the examination object arranged on the patient support plates to be accessed from several sides, in particular from below the patient support plates. This enables a particularly gentle arrangement and / or positioning of the examination object, in particular in the supine position and / or prone position, on the patient positioning device, with simultaneous accessibility from the respective positioning side. If the accessibility requirement to the examination object is changed according to the intervention workflow, this can be ensured by moving the at least one support element.

Furthermore, the intervention workflow can require maximum stability of the patient support device with respect to the action of a force in at least one section of the at least one patient support plate, for example during a resuscitation of the examination subject and / or a surgical intervention. For this purpose, the movement of the at least one support element can be controlled as a function of the intervention workflow in such a way that maximum stability against the action of force is guaranteed in the at least one section of the at least one patient support plate. For example, the at least one support element can be moved under the at least one section of the at least one patient support plate.

In a further advantageous embodiment of the proposed patient support device, the at least one patient support plate can have a coupling element to the at least one support element. The at least one support element and the at least one patient support plate can be coupled mechanically and / or electromagnetically, in particular movably, by the coupling element.

In this case, the coupling element can be designed, for example, as a rail, in particular a guide rail, and / or a bearing, in particular a ball head bearing. The at least one support element can advantageously have a receiving element that corresponds to the respective coupling element of the at least one patient support plate. The receiving element can advantageously be designed as a holder and / or receptacle. Furthermore, the at least one patient support plate and / or the arrangement of the several patient support plates can be pushed onto the at least one support element.

With a reversibly fixed mechanical and / or electromagnetic coupling between the at least one support element and the at least one patient support plate, the at least one patient support plate can be moved along with a movement of the at least one support element.

Furthermore, with a movable mechanical and / or electromagnetic coupling between the at least one support element and the at least one patient support plate, for example when the at least one coupling element is designed as a rail system, a movement of the at least one support element decoupled from the at least one patient support plate can be enabled. In this way, a movement, in particular an evasive movement, of the at least one support element can be made possible without influencing the positioning of the at least one patient support plate, in particular the examination object arranged thereon. The at least one coupling element can advantageously enable the at least one patient support plate to be locked at least temporarily with respect to the at least one support element. In this way, the stable support of the at least one patient support plate by the at least one support element can advantageously be ensured.

In a further advantageous embodiment of the proposed patient support device, the patient support device can comprise at least two support elements. The at least two support elements can each include a processing unit which is designed for coordinated control of the support elements. Furthermore, the processing units can be designed to receive the proximity signal. The processing units can control a movement of their respective support elements in such a way that an evasive movement of at least one first support element takes place by means of its first movement device along the horizontal plane as a function of the approach signal and the at least one first support element and / or at least one further support element stable the at least one patient support plate supports.

In this case, at least a first of the processing units of the at least two support elements can advantageously be designed to control the at least one other processing unit. Furthermore, the processing units can be designed for, in particular mutual, provision and / or reception of positioning information from the at least two support elements. In this case, the positioning information of one of the at least two support elements can advantageously include information on the, in particular momentary, spatial position and / or orientation and / or pose, in particular with regard to at least one first support element. The coordinated control of the support elements can advantageously take place as a function of the positioning information of the at least two support elements.

Furthermore, the movement of the at least two support elements within the horizontal plane can be controlled in a coordinated manner such that the at least two support elements do not collide with one another and / or with a physical object, for example a medical device and / or an operator. The at least two support elements can be moved in such a way that stable support of the at least one patient support plate is ensured by the spatial arrangement, in particular positioning, of the at least two support elements with respect to one another. Furthermore, the movement of the at least two support elements can take place in such a way that the at least one patient support plate is stably supported by one support element in each case, while the at least one first support element performs an evasive movement as a function of the approach signal. As a result of the coordinated control of the movement of the at least two support elements, it is advantageously possible to achieve a higher tilting stability with a simultaneous evasive movement. Furthermore, the evasive movement can advantageously take place independently of a positioning of the examination subject on the at least one patient support plate through the coordinated control of the support elements.

In a further advantageous embodiment of the proposed patient support device, the at least two support elements can each comprise a second movement device which is designed to adjust the height of the support element. The evasive movement of the at least one first support element can take place by means of the first and the second movement device along the horizontal plane and / or in a vertical direction as a function of the approach signal.

At least one further support element of the at least two support elements can stably support the at least one patient support plate. Furthermore, the movement of the at least one first support element of the at least two support elements, in particular along the vertical direction, can take place by means of the second movement device in such a way that the at least one first support element does not support the at least one patient support plate. At least a first one can do that Support element can be retracted and / or folded, for example. Furthermore, the at least one first support element can be released from the at least one patient support plate during the coordinated movement. The evasive movement can take place in the vertical direction away from the at least one patient support plate. This enables an evasive movement of the at least one first support element that is independent of the at least one patient support plate.

Alternatively, the at least one first support element can also be mechanically and / or electromagnetically coupled to the at least one patient support plate during the coordinated movement. The evasive movement can be directed along the vertical direction towards the at least one patient support plate.

In a second aspect, the invention relates to a movable medical device, comprising a proposed patient support device. The medical device is designed to provide the approach signal as a function of at least one operating parameter.

The advantages of the movable medical device according to the invention essentially correspond to the advantages of the patient support device according to the invention, which are detailed in advance. Features, advantages or alternative embodiments mentioned here can also be transferred to the other claimed subjects and vice versa.

The movable medical device can be used, for example, as a medical imaging device, for example a medical x-ray device, in particular a C-arm x-ray device, and / or a computed tomography system (CT) and / or magnetic resonance system (MRT) and / or ultrasound device, and / or a medical device Monitoring of the examination subject, in particular an EKG device, and / or an anesthesia device and / or an irradiation device can be designed. Furthermore, the at least one operating parameter can advantageously include an acquisition parameter, for example a medical imaging method, and / or positioning information, in particular with regard to the patient positioning device, and / or a planned movement path of the medical device, for example in a medical irradiation method. Furthermore, providing the proximity signal to the processing unit of the at least one support element can include, in particular, storage on a computer-readable storage medium and / or, in particular wireless, transmission from the medical device to the processing unit of the at least one support element.

Furthermore, the proposed patient support device can be arranged on the medical device and / or can be coupled to it, in particular mechanically. The movement of the at least one support element of the patient support device can advantageously be controlled by the processing unit in such a way that the support element stably supports the at least one patient support plate and performs an evasive movement with respect to the movable medical device.

In a third aspect, the invention relates to a method for moving a patient support device. The patient support device comprises at least one patient support plate and at least one support element. Furthermore, the at least one support element comprises a first movement device which is designed to translate and rotate the at least one support element in a horizontal plane. Furthermore, the at least one support element further comprises a processing unit which is designed to control the at least one support element. The processing unit is also designed to receive an approach signal. Here, the proposed method for moving the patient support device comprises a first step a), wherein the approach signal is received. Furthermore, in a second step b) the at least one support element is moved by means of the first movement device in such a way that the at least one patient support plate is stably supported by the at least one support element and an evasive movement is performed along the horizontal plane as a function of the approach signal.

Receiving the approach signal in step a) can in particular include capturing and / or reading out a computer-readable data memory and / or receiving it from a data storage unit. In particular, the proximity signal can be provided by a medical device and / or a proximity sensor to the processing unit of the at least one support element.

Furthermore, the approach signal can advantageously include information on a change in position and / or movement of a physical object and / or an operating personnel in a, in particular predetermined, spatial environment of the at least one support element, in particular along a direction of movement towards the at least one support element. The approach signal can also provide information on the speed of movement and / or direction of movement and / or movement trajectory of the detected physical object and / or operating personnel. Furthermore, the processing unit can control the movement of the at least one support element as a function of the approach signal in such a way that the at least one support element evades the detected object and / or operating personnel by means of the first movement device along the horizontal plane. In this case, the movement of the at least one support element can comprise a time sequence of, in particular simultaneously executed, translations and / or rotations of the at least one support element along the horizontal plane.

The movement of the at least one support element can in particular take place autonomously as a function of the received proximity signal. Furthermore, this advantageously enables collision-free driving under the patient support device through the evasive movement of the at least one support element, which is carried out, in particular autonomously. Furthermore, the tilting stability of the patient support device is advantageously ensured at all times by the stable support of the at least one patient support plate by the at least one support element.

In a further advantageous embodiment of the proposed method, the at least one support element can be moved in such a way that a positioning of an examination object arranged on the at least one patient support plate remains unchanged.

The movement of the at least one support element in step b) can advantageously take place both with respect to the room underground and with respect to the at least one patient support plate, in particular in the same direction. Here, the at least one support element can preferably be moved by means of the first movement device along the horizontal plane both with respect to the at least one patient support plate and with respect to the floor of the room. It can thus be achieved that the at least one patient support plate and the examination object arranged thereon advantageously remain at rest while the at least one support element is moved by means of the first movement device. The movement of the at least one support element with respect to the at least one patient support plate can be viewed as a movement of the at least one patient support plate with respect to the at least one support element by means of the first movement device, which is opposite to the movement of the at least one support element with respect to the room underground.

By maintaining a positioning of the examination object arranged on the at least one patient support plate, movement artifacts can advantageously be avoided. Furthermore, the collision-free passage under the patient support device can be made possible at the same time.

In a further advantageous embodiment of the proposed method, the patient support device can comprise at least two support elements. The at least two support elements can each include a processing unit which is designed for coordinated control of the support elements. The processing units can also be designed to receive an approach signal. In addition, the proposed method can further include a step c), wherein at least one first support element can be moved in a coordinated manner such that the at least one first support element executes an evasive movement by means of its first movement device along the horizontal plane as a function of the approach signal. Furthermore, at least one further support element can be coordinated in step b) in such a way that the at least one patient support plate is stably supported by the at least one first support element and / or the at least one further support element.

The movement of the at least one first support element can be coordinated in particular as a function of the approach signal and the spatial position of the at least one further support element with respect to the at least one patient support plate and / or with respect to the at least one first support element. In particular, the coordination can include a control of the movement of the at least one first support element by the associated processing unit and / or the processing unit of the respective at least one further support element. In this case, the at least one patient support plate can be supported in a stable manner by the at least one further support element, in particular alone, while the at least one first support element performs the evasive movement. Furthermore, the at least one first and the at least one further support element can be moved in a coordinated manner such that the at least one patient support plate is stably supported by the at least one first and the at least one further support element, in particular the common arrangement. Furthermore, the movement of the at least one first and the at least one further support element can be coordinated in such a way that positioning of the at least one patient support plate, in particular the examination object arranged thereon, is maintained.

As a result, greater stability can be achieved with regard to the support of the at least one patient support plate by the at least two Support elements are made possible with simultaneous evasion in front of an objective object and / or an operator.

In a further advantageous embodiment of the proposed method, the at least two support elements can each comprise a second movement device which is designed to adjust the height of the respective support element. The at least one first support element can be moved in step c) by means of the first and the second movement device as a function of the approach signal along the horizontal plane and / or in a vertical direction.

This advantageously enables an improved adaptation of the at least two support elements to an arrangement of the at least one patient support plate that is tilted and / or pivoted relative to the horizontal plane by moving the respective support element along the vertical direction by means of the second movement device. Furthermore, the coordinated movement of the at least two support elements can be controlled in such a way that, in addition to the at least one first support element, at least one patient support plate is moved as a function of the approach signal. In particular, the evasive movement of the patient support device can comprise an evasive movement of the at least one first support element and the at least one patient support plate.

Furthermore, when an objective object and / or an operator approaches the at least one first support element, an evasive movement of the at least one first support element can take place as a function of the received approach signal. For example, the at least one first support element can be moved along the horizontal plane and / or in a vertical direction. The at least one first support element can advantageously have a smaller spatial extent along the vertical direction due to the movement along the vertical direction by means of the second movement device. In this way, it can be achieved that the object in question and / or the operating personnel can pass, in particular drive under and / or cross the at least one first support element, in particular without collision. Meanwhile, the at least one patient support plate can be stably supported by the at least one further support element.

If the at least one further support element detects an approach of the same and / or a further objective object and / or operating personnel on the basis of the received approach signal, steps b) to c) can be repeated. The at least one first support element can be specified as the at least one further support element in step b) and the at least one further support element as the at least one first support element in step c).

This advantageously enables collision-free driving under the patient support device, in particular the examination object arranged thereon.

In a further advantageous embodiment of the proposed method, the proximity signal can be provided by a medical device. The approach signal can also include a planned movement path of the medical device. Furthermore, the at least one first support element can be moved in step c) in such a way that it evades the planned movement path of the medical device. Furthermore, steps b) to c) can be repeated when the medical device approaches the at least one further support element. The at least one first support element can be specified as the at least one further support element in step b) and the at least one further support element as the at least one first support element in step c).

The movement of the at least two support elements can advantageously be coordinated in such a way that the at least one first support element evades the medical device and the at least one patient support plate is supported in a stable manner. Furthermore, the movement of the at least two support elements can be coordinated particularly efficiently based on the planned movement path. For example, the at least two support elements can be moved in a coordinated manner such that as few further evasive movements as possible are necessary when the medical device moves along the planned movement path. At the same time, it can advantageously be ensured that the at least one patient support plate is supported in a stable, in particular non-tilting manner.

Because the at least one first support element is specified as the at least one further support element in step b) and the at least one further support element is specified as the at least one first support element in step c), one can advantageously be positioned along the horizontal plane below the at least one patient support plate continuous movement of the medical device can be made possible. As soon as the medical device has passed, in particular passed under and / or crossed the at least one first support element after the evasive movement of the at least one first support element, the at least one first support element can be moved in a coordinated manner such that it stably supports the at least one patient support plate. The method described above can then be carried out repeatedly along the planned movement path.
