Description

Background Technology

[0001] This bed board cover is part of the patient support equipment.

[0002] Patient support devices, such as those in the form of examination tables, are used to support patients during magnetic resonance imaging (MRT), computed tomography (CT), positron emission tomography (PET), and / or irradiation. The materials of the patient support device must not be visible in the imaging. Furthermore, the materials must be sufficiently stable to support the weight of the patient.

[0003] Patients can be moved, for example, before and / or during imaging methods and / or irradiation, via a patient support device. For reliable patient movement to be possible and to avoid deformation during imaging and / or irradiation, the patient support device needs to have sufficient mechanical stability.

[0004] In computed tomography applications (such as CT or MRT), it is crucial to minimize the deflection of the CT bed. Particularly critical is ensuring that the vertical position of points on the CT bed (e.g., the head) changes as little as possible when entering and leaving the field of view (FoV). If the vertical position at the beginning of the FoV deviates significantly from its vertical position at the end of the FoV, streaks or other abnormalities will appear in the CT images.

[0005] Furthermore, the slabs used for tomography applications are typically arched laterally on the upper side. The slabs for radiotherapy planning are flat on the upper side. Radiotherapy planning on a curved slab can cause the area to be irradiated to be in a different location during actual radiotherapy.

[0006] To date, the proposed solution has been to minimize deflection through a mechanically rigid construction of the bed and bed frame. However, the increased use of material in the bed frame leads to increased signal attenuation, such as X-ray attenuation. Therefore, the proposed solution is limited.

[0007] In methods such as computed tomography or molecular imaging methods such as positron emission tomography (PET), double-shell bed plates have traditionally been used to provide sufficient rigidity. In such a construction, for example, two shells made of carbon fiber reinforced plastic (CFK) are used, surrounding a cavity that is foamed or filled with polymethacrylamide or wood.

[0008] In order to achieve a stable support state with the bed board as thin as possible, a curved aluminum bed board can be used, for example, in certain systems. This aluminum bed board is accommodated and supported, for example, by a support device also known as a rear bed, when it is moved into the imaging device.

[0009] Therefore, a normally flat cover, also known as a bed board cover, is placed on a CT bed with a transversely arched bed board used for radiotherapy planning. The cover is fixed to the bed at the clamping point of the bed board. Here, the cover floats on the bed board, so that no shear stress is transmitted from the cover to the bed board under load. Therefore, the cover lies freely flat on the bed board. This method has an adverse effect on deflection. Summary of the Invention

[0010] Therefore, the object of the present invention is to provide a bed board cover that has improved mechanical stability and less total deflection. In particular, the object of the present invention is to provide a patient support device that enables improved quality of images generated during medical imaging of the patient and / or allows for more targeted dose administration when irradiating the patient.

[0011] According to the invention, the objective is achieved by the bed board cover according to the invention and the patient support device according to the invention. Advantageous designs of the invention are shown in the description and drawings.

[0012] This invention relates to a bed board cover for an examination bed. The bed board cover is configured to support a patient, for example, by having the patient lie on the bed board cover. The bed board cover is configured, for example, to compensate for the examination bed in terms of height, curvature, or tilt. The examination bed is configured to support the patient during medical imaging, particularly computed tomography (CT) or magnetic resonance imaging (MRI), especially during irradiation, thereby positioning the patient. In particular, the examination bed, bed board cover, and / or patient support device are compatible with use in medical imaging, MRI, CT, positron emission tomography (PET), and / or irradiation. The bed board cover and the examination bed are preferably patient support devices, such as part of a bed.

[0013] The examination bed board is configured to accommodate a bed board cover. For example, the examination bed board at least partially accommodates the bed board cover in a form-fitting and / or force-fitting manner. For example, the bed board cover rests at least partially flat on the examination bed board, preferably at least in the head section and foot section. In particular, the examination bed board forms a frame at least partially, preferably in the head section and / or foot section. The bed board cover is preferably placed on and / or supported by the examination bed board.

[0014] The bed cover is particularly planar in shape. The bed cover may have a flat planar extension; alternatively, the bed cover may have a curved planar extension. The bed cover is particularly resistant to bending. For example, the bed cover is made of plastic, especially a laminated material, or metal. The bed cover preferably has a substantially rectangular shape in a top view.

[0015] A bed board cover, particularly an examination bed board, has a first end section and a second end section. The first and second end sections are spaced apart in the longitudinal direction. An intermediate section, also called a middle section, is provided between the first and second end sections. The first and second end sections are provided in the regions at both ends of the bed board cover in the longitudinal direction. In other words, the first end section forms one end of the bed board cover, and the second end section forms an end in the opposite direction in the longitudinal direction. The middle section is particularly provided between the first and second end sections.

[0016] Two end sections and a middle section divide the planar extension of the bed board cover into three parts. Preferably, the end sections each comprise between five percent and ten percent of the area. In particular, the first and second end sections extend over a maximum of ten percent of the longitudinal extension, respectively.

[0017] The examination bed has a first coupling interface and a second coupling interface. The first and second coupling interfaces are spaced apart, particularly in the longitudinal direction. The first coupling interface is configured to be coupled to a first mating coupling interface. The second coupling interface is configured to be coupled to a second mating coupling interface. Preferably, the coupling between the first coupling interface and the first mating coupling interface and / or between the second coupling interface and the second mating coupling interface is reversible. The first and second coupling interfaces are preferably based on different coupling mechanisms.

[0018] The bed board cover has a first mating coupling interface in its first end section. In its second end section, the bed board cover has a second mating coupling interface. The first mating coupling interface is configured to be coupled and / or connected to the first coupling interface. The second mating coupling interface is configured to be connected and / or coupled to the second mating coupling interface.

[0019] When the first mating coupling interface is coupled or connected to the first coupling interface, and the second mating coupling interface is coupled and / or connected to the second coupling interface, the bed board receiving part and / or the patient support device occupies the coupled or connected state. The coupled state, especially the coupling and / or connection between the first coupling interface and the first mating coupling interface and / or between the second coupling interface and the second mating coupling interface, is releasable and / or reversible. The coupling and / or connection between the first mating coupling interface and the first coupling interface is, for example, a tensile connection, a shear connection, a hook-and-eye connection, a form-fit connection, and / or a force-fit connection.

[0020] In the coupled state, the first coupling interface applies and / or transmits force to and / or via the first mating coupling interface. In other words, the first mating coupling interface is loaded with force, particularly tensile and / or tensional force, through coupling with the first coupling interface. The force acts particularly in the longitudinal direction, especially with an orientation from the second end section to the first end section. The force, particularly tensile and / or tensional force, acts on the bed cover through the first mating coupling interface, particularly on the first end section of the bed cover.

[0021] By coupling and / or connecting the second mating coupling interface to the second coupling interface, a form fit and / or force fit is created between the bed board cover and the inspection bed board. In other words, in the coupled state, the second mating coupling interface is connected to the second coupling interface in a form fit and / or force fit manner. The coupling between the second mating coupling interface and the second coupling interface is, for example, a plug connection, a mortise and tenon connection, a form fit connection, and / or a force fit connection.

[0022] The present invention is based on the concept of creating a mechanically particularly stable cover for supporting the patient by connecting the bed cover to the examination bed plate at two free ends or two end segments via coupling interfaces according to the invention. In particular, the invention utilizes the so-called Fin-Ray effect, which resists displacement and / or strong localized deflection, through two couplings. Specifically, a substantially constant distance is achieved between the bed cover and the examination bed plate through the proposed connection, particularly through two couplings.

[0023] Particularly preferred is that the first end segment corresponds to and / or forms the head segment. The head segment, particularly the following segments and / or end regions of the bed board cover and / or examination bed board, typically supports the head during patient support and / or is closest to the head in these segments and / or end regions. The second end segment is particularly configured as a foot segment and / or corresponds to the foot segment. In other words, the second end segment corresponds to the following regions and / or segments of the bed board cover and / or examination bed board, where the foot is typically located during patient support, and / or is closest to the foot. It is particularly proposed that a first mating coupling interface and / or a first coupling interface are provided in the head segment, wherein a second mating coupling interface and / or a second coupling interface are provided in the foot segment. With the aforementioned design, the bed cover is form-fitted and / or force-fitted to the examination bed in the foot section, and the bed cover is form-fitted and / or force-fitted to the examination bed in the head section for applying force. Specifically, tensile and / or tension forces, or force loading, are applied in the head section along the longitudinal direction.

[0024] Particularly preferred is that the first mating coupling interface is a tensioning interface (Spannschnittstelle) for transmitting tension and / or tensile force as a force load. In other words, the tensioning interface is configured to transmit tension and / or tensile force to the first mating coupling interface or to the bed board cover. In particular, the tensioning interface is configured to induce and / or transmit a settable tension and / or tensile force, for example, in the form of a preload. The first coupling interface particularly forms a tensioning interface for coupling with the tensioning interface of the first mating coupling interface. The first mating coupling interface and / or the first coupling interface may, for example, include a tensioning rod, a tensioning mechanism, and / or a tensioning spring.

[0025] Particularly preferred is that the first coupling interface includes an eyelet, a lug, and / or a hooking element. The first mating coupling interface here has a hook and / or a hooking element. In the coupled state, the hook of the first mating coupling interface enters the eyelet, lug, and / or the first mating coupling interface. It is also particularly conceivable that the first coupling interface includes a hook and the first mating coupling interface includes an eyelet or lug. The hook, for example, is screwed onto the bed board cover.

[0026] Particularly preferred is that the second mating coupling interface forms a plug-in connection interface. The second coupling interface here forms a mating part for the plug-in connection interface. In the coupled state, the bed board cover and the examination bed board are coupled via the second coupling interface through a plug-in connection and / or in the form of a plug-in connection. Here, the second coupling interface is particularly configured to receive and / or insert into the second mating coupling interface. In other words, the second mating coupling interface preferably forms a plug for the second coupling interface and / or the second coupling interface preferably forms a socket, pocket, or recess to receive the second mating coupling interface.

[0027] Optionally, the second coupling interface may have or form a groove, a pocket, and / or a material recess. The second mating coupling interface here particularly includes and / or forms a tenon, an eversion, or a tongue. The second coupling interface here is configured to receive, particularly form-fit, the second mating coupling interface. For example, the second coupling interface, particularly in the second end section, includes an edge section of the examination bed board. The second mating coupling interface is particularly configured to form-fit the edge section and / or a portion of the examination bed board.

[0028] In one possible design of the invention, a first mating coupling interface is provided on the upper side of the bed board cover. The upper side of the bed board cover, particularly the side of a planar bed board cover on which the patient is supported or on which the patient lies, is the first mating coupling interface. The second mating coupling interface is preferably provided on the lower side of the bed board cover, wherein the lower side, particularly the side of the bed board cover facing the examination bed board in the coupled state, is the first mating coupling interface.

[0029] Patient support devices form another subject of the invention. Patient support devices are particularly configured to support, especially position, and / or move a patient for medical imaging and / or irradiation. Patient support devices, for example, include or form an examination bed plate. The patient support device includes an examination bed plate cover according to the invention, as previously described. The bed plate cover is connected and / or coupled to the examination bed plate in a coupled state via a first coupling interface and a first mating coupling interface. Furthermore, the bed plate cover is force-fitted and / or form-fitted connected and / or coupled to the examination bed plate in a coupled state via a second coupling interface and a second mating coupling interface. In particular, in the coupled state, the bed plate cover is loaded with a force acting in the longitudinal direction, particularly a tension force and / or a pulling force. The force-fitted and / or form-fitted connection or coupling of the second coupling interface and the second mating coupling interface particularly results in substantially equidistant spacing.

[0030] Patient support devices, particularly examination bed boards, may optionally include a connecting module. The connecting module particularly has a first coupling interface. The examination bed board has a reclining section. This reclining section is particularly a planar section, especially the upper section. The reclining section is, for example, a section on which the patient can be supported when using an examination bed board without a bed board cover. In other words, the reclining section forms a reclining surface.

[0031] The connecting module is form-fitted to the examination bed board, particularly in the lying section, and especially form-fitted. Preferably, the connecting module is screwed onto the examination bed board. The connecting module is preferably constructed in a block, square, and / or solid manner. For example, the connecting module comprises a plastic block for a particularly solid, robust, and / or stable embodiment. In particular, the connecting module is located in the region of the first end section and / or head section. The connecting module preferably includes a first coupling interface. Thus, the examination bed board can be used to support the patient without the connecting module and is provided with a first coupling interface by connection to the connecting module, allowing the use of the bed board cover according to the invention.

[0032] Furthermore, it is particularly preferred that the patient support device includes a splint module. The splint module is planar in shape. Preferably, the splint module is resistant to bending, for example, it is constructed as an aluminum plate, steel plate, plastic plate, or sheet metal plate. The splint module is preferably at least partially aligned with a section of the lying-down section. The splint module includes a clamping area and a reinforcing area. The clamping area is particularly the end section of the planar splint module. In the coupled state, the clamping area is disposed or clamped between the lying-down section or examination bed and the connecting module. In other words, the clamping area of ​​the splint module is clamped between the lying-down section or examination bed by the form-fitting connection of the connecting module with the lying-down section or examination bed, and is held in a force-fitting and / or form-fitting manner. In particular, by tightening or form-fitting the connecting module to the examination bed, the clamping area or splint module is also tightened and / or form-fitted together.

[0033] The splint module has a reinforcement area, at least partially formed in a ground-like manner. The splint module is connected in the reinforcement area to the reclining section or examination bed board in a shape-fitting manner. Preferably, the splint module is screwed to the reclining section or examination bed board in the reinforcement area. The reinforcement area is configured to reinforce and / or mechanically stabilize the reclining section.

[0034] Optionally, the first coupling interface includes a preload unit. The preload unit, for example, has a preload rod or rotating element for setting a preload, tension, or force application. The preload unit is configured to induce a settable preload, such as tension or tension, on the first mating coupling interface in the coupled state. In other words, the tension and / or tension acting on the first mating coupling interface or the bed cover can be set by means of the preload unit.

[0035] The examination bed board and / or reclining section particularly include a second foot section. The second foot section is spaced longitudinally from a second head section of the examination bed board. The free ends and / or edge regions of the second foot section preferably form a second coupling interface. In other words, the second foot section and / or edge regions form tenons, tongues, and / or flanges for form-fitting reception via the second coupling interface, which is particularly in the form of a groove or pouch. The second coupling interface, particularly a recess, groove, or pouch, at least partially form-fits the free ends of the second foot section. Therefore, the form-fitting connection between the bed board cover and the examination bed board can be achieved particularly simply and stably by accommodating the foot section in the pouch, groove, or recess.

[0036] Particularly preferred is that the reclining section, especially the examination bed board, is concave in the transverse direction orthogonal to the longitudinal direction, wherein the bed board cover is preferably constructed to be planar and / or unbent. In other words, the bed board cover is configured to transform the curved, especially concave, reclining section of the examination bed board into a planar reclining surface, so as to support the patient, for example, for irradiation. This allows an examination bed board, which is typically curved for imaging, to be used for irradiation by means of the bed board cover.

[0037] Patient support equipment, particularly the coupling state of the examination bed board and bed board cover, is based on and / or achieves the Fin-Ray effect, enabling the patient support equipment to resist excessive deflection of the lying section. The Fin-Ray effect is derived in particular from the coupling of the form fit and / or force fit between the bed board cover and the examination bed board in the first and second end sections.

[0038] Particularly preferred is that the bed board cover and / or examination bed board are made of fiber composite materials, especially carbon fiber reinforced plastic (CFK). This allows the bed board to have the lowest possible aluminum equivalent, thus minimizing its impact on imaging. Attached Figure Description

[0045] Figure 1 An embodiment of a patient support device 1 is shown. The patient support device 1 is configured as a bed or formed part of a bed for supporting a patient, for example. The patient support device 1 is used, for example, during imaging examinations of a patient using computed tomography (CT) or magnetic resonance imaging (MRI). Furthermore, the patient support device 1 is used only to support a patient during irradiation in tumor treatment. The patient support device 1 is particularly a movable examination bed, such as a mobile examination bed.

[0046] The patient support device 1 includes a bed board cover 2 and an examination bed board 3. The patient support device 1 without the bed board cover 2, in other words, the examination bed board 3, is used, for example, to support the patient during medical imaging, since the patient is typically supported on a convex, curved lying surface. For irradiation, the patient is supported on a flat lying surface, and medical imaging for irradiation planning is performed while the patient is supported in a flat position. The examination bed board 3 with a curved lying surface can be modified for use during irradiation by placing the bed board cover 2 on, and in particular, coupling it to, the examination bed board 3. The bed board cover 2 and the examination bed board 3 are coupled or connected via a first mating coupling interface 4 and a second mating coupling interface 5. This coupling or connection is reversible and / or releasable.

[0047] The bed board cover 2 is rectangular in the top view. The bed board cover 2 extends at least 1.8 m in the longitudinal direction L. In the transverse direction Q, the bed board cover 2 extends at least 60 cm, also referred to as its width. The bed board cover 2 is planar in shape, particularly in the longitudinal direction L and the transverse direction Q. The bed board cover 2 is, for example, plate-like or platform-like and has a thickness or material thickness of less than 5 cm.

[0048] The bed board cover 2 includes a first end segment 6, a second end segment 7, and an intermediate region, also referred to as a middle segment 8. The two end segments 6 and 7 are defined in particular by the longitudinally spaced ends of the planar bed board cover 2, with the middle segment 8 located between the two end segments 6 and 7. Along the longitudinal direction L, the bed board cover 2 has index marks 9, which can be used to locate the patient during imaging or irradiation.

[0049] The patient support device 1 includes a connection module 10, which is form-fitted to the examination bed board 3. The connection module 10 includes a first coupling interface 11, configured to be coupled to a first mating coupling interface 4. Through the coupling of the first mating coupling interface 4 and the first coupling interface 11, a tensile force F acting in the longitudinal direction L is transferred. Z It is transferred to the bed board cover 2, especially to the first end section 6.

[0050] Figure 2 An embodiment of an examination bed board 3 is shown. The examination bed board 3 has a reclining section 12, which is convexly curved and configured to support the patient. For example, the examination bed board 3, especially the reclining section 12, is configured as a semi-shell. The examination bed board 3 extends in the longitudinal direction L and has a first end 13 and a second end 14. The second end 14 is preferably located in the foot region. The free second end 14 forms a second mating coupling interface 5, which can be inserted into a pocket-like portion to form a plug-in connection.

[0051] The inspection panel 3 is connected to and / or includes the connecting module 10. The connecting module 10 forms a fixing block. The connecting module 10 includes a first coupling interface 11, which is configured as a tension rod and / or includes the tension rod. The coupling interface 11 includes an eyelet. A first mating coupling interface 4 includes a hook that can engage with the eyelet. The tension F obtained on the hook via the eyelet can be set by the tension rod. Z Tighten the connecting module 10 to the inspection bed board 3.

[0052] A clamping module 15 is provided between the connecting module 10 and the examination bed board 3 or the reclining section 12. The clamping module 15 includes a clamping area and a reinforcing area 16. The clamping area is disposed and / or clamped between the reclining section 12 and the connecting module 10. The reinforcing area 16 extends longitudinally from a first end 13 to a second end 14. The reinforcing area 16 is planar and particularly coincides with a sub-region of the reclining section 12. The clamping module 15 is tightened to the reclining section 12 in the reinforcing area 16 to ensure improved mechanical stability.

[0053] Figure 3 Show Figure 1The bed board cover 2 is included. The bed board cover 2 includes a hook as a first mating coupling interface 4. The first mating coupling interface 4, in particular the hook, is screwed onto the bed board cover 2.

[0054] Figure 4 Show Figure 1 or Figure 3 A detailed view of the bed board cover 2. The bed board cover 2, serving as the second mating coupling interface 5, includes a pouch-like portion on its underside as a receiving portion for the second coupling interface 17. The pouch-like portion of the second mating coupling interface 5 matches the contour of the second end 14 of the examination bed board 3 and is formed in an arcuate shape. The arcuate design is derived from the convex curvature of the examination bed board 3. The pouch-like portion shape fits to accommodate the second coupling interface 17, particularly the edge of the examination bed board 3. Therefore, the bed board cover 2 connects to the examination bed board 3 at two locations: in the first end section 6 and in the second end section 7.

[0055] Figures 5a, b, and c show FEM simulations of the patient support device 1. The patient support device 1 forms a Fin-Ray structure. The Fin-Ray structure is derived in particular by the form-fit connection in the second end segment 6 and the form-fit connection in the first end segment 5. Figure 5a shows the deflection D1 of the patient support device 1 when the patient support device is connected according to the invention via the first and second coupling interfaces 11, 17. This confirms that even under strong loads, such as in the case of a heavy patient, the deflection remains small. The deflection D2 of the patient support device without two connections or couplings according to the invention is significantly stronger and is the largest in the end regions 6, 7.

[0056] Figure 5b illustrates the deformation or compression of the patient support device 1 when supporting a heavy patient. Here, the region of maximum deflection for the patient support device 1 according to the invention is not located on the end sections 5 and 6. The distribution of gravity within the planar extension of the lying surface is shown in Figure 5c.
