[0005] US 5,433,222 A describes a fastening element for attaching a belt to a rail element. However, in this case, the fastening element is arranged around the rail element.

[0006] The present invention is based, in particular, on the object of providing a belt fastening device that enables simple and secure fastening and / or fixation of safety belts for a medical imaging examination. This object is achieved by the features of the independent claims. Advantageous embodiments are described in the subclaims.

[0007] The invention is based on a belt fastening device for fastening safety belts, wherein the belt fastening device has at least one fastening rail and at least one fastening clamp.

[0008] It is proposed that the at least one fastening clamp has a belt fastening element, and that the belt fastening element is arranged within the at least one fastening rail in a state of the at least one fastening clamp arranged with the at least one fastening rail. According to the invention, the at least one fastening clamp has an actuating element, wherein a force perpendicular to the longitudinal extent of the at least one fastening rail, on which the actuating element acts, is applied to release a locking mechanism between the at least one fastening clamp and the at least one fastening rail.

[0009] The belt fastening device according to the invention is designed in particular for fastening objects, in particular a patient and / or additional units, to a patient support device, in particular a couch table of the patient support device. Preferably, the belt fastening device according to the invention is also designed for medical imaging examinations on the patient using medical imaging devices. The belt fastening device according to the invention can also be included in the patient support device. For example, the fastening rail can be arranged within a couch table of the patient support device. Alternatively or additionally, the belt fastening device can also be at least partially included in accessory units.For example, the at least one fastening rail and / or the at least one fastening clamp can be comprised by a local magnetic resonance coil device.

[0010] The at least one fastening clamp and the at least one fastening rail are preferably formed from mutually corresponding elements, so that for fastening a safety belt, this safety belt is arranged on the at least one fastening clamp, and the at least one fastening clamp can be fastened within the at least one fastening rail. An arrangement, in particular a fastening and / or fixing of the at least one fastening clamp within the at least one fastening rail, takes place exclusively by means of the at least one fastening rail and the fastening clamp corresponding to the at least one fastening rail, so that no further units and / or components are required for this purpose.

[0011] In this context, "arranged within the fastening rail" should be understood in particular to mean that the belt fastening element is arranged at least 70% within the fastening rail, and preferably at least 85% within the fastening rail. However, it is particularly advantageous for the belt fastening element to be arranged entirely within the fastening rail, so that the belt fastening element does not protrude from the fastening rail when the fastening clamp is arranged with the fastening rail.

[0012] The belt fastening device according to the invention advantageously achieves a high level of patient comfort, since patient impairment due to the belt fastening element can be at least reduced or even prevented compared to conventional belt fastening devices. Furthermore, a particularly space-saving and compact arrangement of the belt fastening device can be achieved. Furthermore, the belt fastening element and also the arrangement of a safety belt on the belt fastening element can be advantageously protected from undesirable interference and / or damage.

[0013] It is further proposed that the at least one fastening clamp has a base element on which the belt fastening element is arranged. This not only provides high stability for the belt fastening element but also provides advantageous protection for the safety belt arrangement.

[0014] When the at least one fastening clamp is arranged with the at least one fastening rail, the base element is preferably also arranged at least 70% within the at least one fastening rail. The base element is preferably arranged at least 80% within the fastening rail and particularly preferably at least 85% within the fastening rail. However, it is particularly advantageous if the base element is arranged at least 90% within the fastening rail, so that the belt fastening element does not protrude from the fastening rail. This embodiment of the invention can ensure advantageous protection for the base element, so that when the fastening clamp is arranged on the fastening rail, damage to the base unit can be advantageously prevented.In addition, this can also provide a high level of comfort for the patient, since any disability to the patient caused by the belt fastening device can at least be reduced and / or prevented.

[0015] Particularly high stability of the at least one fastening clamp can advantageously be achieved if the base element is U-shaped with two leg elements and the belt fastening element is arranged between the two leg elements. Preferably, the belt fastening element is arranged with a first end region on a first of the two leg elements and with a second end region on a second of the two leg elements. The belt fastening element is preferably web-shaped, so that a safety belt of the belt fastening device can be guided around the belt fastening element.

[0016] In an advantageous development of the invention, it is proposed that the at least one fastening clip has an actuating element. In this way, simple actuation, in particular a release of the at least one fastening clip from the fastening rail and / or a fixation of the at least one fastening clip within the fastening rail, can be advantageously achieved for medical personnel. The medical personnel can particularly preferably exert a force on the fastening clip via the actuating element, for example in order to displace the fastening clip within the fastening rail and / or in order to release the fastening clip from the fastening rail in a state arranged with the fastening rail.Preferably, the actuating element is arranged within the fastening clamp in such a way that the actuating element protrudes from the fastening rail in an arranged state of the fastening clamp with the fastening rail and in this way a simple and safe actuation can be carried out by the medical operating personnel.

[0017] Furthermore, it is proposed that the at least one fastening clip comprise a securing element. This allows for advantageous securing of the position of the at least one fastening clip within the at least one fastening rail of the belt fastening device. Particularly advantageously, the securing element comprises a locking element, so that a structurally simple and time-saving securing of the position of the at least one fastening clip within the fastening rail can be achieved.

[0018] In a further embodiment of the invention, the at least one fastening clip has a connecting web for connecting the actuating element to the base element, wherein the securing element is arranged on the connecting web. An advantageous arrangement of the securing element, in particular a locking element, can be achieved in that the securing element is arranged on a region of the fastening clip designed as a spring element. The region designed as a spring element, in particular the connecting web, is designed such that pressure is exerted on the fastening clip, in particular on the actuating element, in order to release the fastening clip from the fastening rail, and this pressure leads to a deformation of the connecting web. Once the pressure on the fastening clip is removed, the connecting web returns to its original shape.This configuration enables a particularly simple release of a fastening position and / or a state of the at least one fastening clamp arranged with the at least one fastening rail for the medical operating personnel.

[0019] Particularly advantageously, the at least one fastening rail has an opening and a maximum width, wherein the width of the opening is at least 60% of the maximum width. Preferably, the width of the opening is at least 75% of the maximum width and particularly preferably at least 80% of the maximum width. This embodiment of the invention makes it possible to particularly easily insert the at least one fastening clip into the at least one fastening rail. Furthermore, the large opening advantageously makes it particularly easy to clean the at least one fastening rail.

[0020] In a further embodiment of the invention, it is proposed that the at least one fastening rail has a longitudinal extension and that the opening has a uniform width in the direction of this longitudinal extension. This allows for particularly simple and secure insertion of the fastening clip into the at least one fastening rail. In particular, the fastening clip can be inserted at any desired location on the at least one fastening rail, thus advantageously simplifying the workflow for medical personnel. Furthermore, this makes it possible to provide a particularly cost-effective and easy-to-manufacture fastening rail.

[0021] In a further embodiment, the at least one fastening rail has a web-shaped rail element that is arranged in an opening region of the at least one fastening rail, wherein the web-shaped rail element is arranged only on an edge region that runs in the longitudinal extent of the at least one fastening rail. This makes it particularly easy to clean the fastening rail, since a concealed region, in particular a region concealed by the web-shaped rail element, is present within the fastening rail only on one side of the fastening rail. Furthermore, the web-shaped rail element can be used to secure the fastening clamp against falling out of the fastening rail, in particular during positioning of the fastening clamp within the fastening rail.Preferably, a second edge region, which also runs in the longitudinal extension of the at least one fastening rail and is opposite the edge region with the web-shaped rail element within the at least one fastening rail, is formed by a rectilinear continuation of a receiving region of the at least one fastening rail.

[0022] In a further embodiment of the invention, it is proposed that the at least one fastening clamp, in a state in which the at least one fastening clamp has a latching connection with the at least one fastening rail, is arranged within the at least one fastening rail so as to be movable in a direction of a longitudinal extent of the at least one fastening rail. In this way, a simple and precise positioning of the fastening clamp in the direction of the longitudinal extent of the fastening rail within the fastening rail can be achieved, thus enabling a particularly simple and precise positioning of a safety belt, since only the position of the fastening clamp in the longitudinal extent of the fastening rail needs to be determined.Preferably, in the state in which the at least one fastening clamp has a snap-in connection with the at least one fastening rail, the at least one fastening clamp is secured by means of the fastening element of the at least one fastening clamp and by means of the web-shaped rail element against falling out of the at least one fastening rail during positioning in the longitudinal extension of the at least one fastening rail.

[0023] Furthermore, it is proposed that the at least one fastening clip locks to the at least one fastening rail when a tensile force acts on the belt fastening element. This allows medical personnel to lock the fastening clip within the fastening rail particularly easily by tightening the safety belt. The locking of the fastening clip to the fastening rail is preferably achieved by tilting the fastening clip within the fastening rail, thus preventing movement of the fastening clip in the longitudinal direction of the fastening rail.

[0024] In an advantageous development of the invention, a force perpendicular to the longitudinal extent of the at least one fastening rail acts on the at least one fastening clamp to release a locking connection between the at least one fastening clamp and the at least one fastening rail. Particularly advantageously, the force for releasing the locking connection acts on the actuating element of the fastening clamp. This allows for particularly simple release of the fastening clamp from a locking connection with the fastening rail. Preferably, the force required to release the fastening clamp acts from the web-shaped rail element to the opposite edge region of the fastening rail.Particularly advantageously, this direction of the force releasing the locking mechanism corresponds to an external direction toward the patient, so that medical personnel do not have to reach between the patient and the belt fastening device, in particular the fastening clip, to release the locking mechanism. Furthermore, this also prevents the patient from accidentally releasing the locking mechanism, for example, during a medical imaging examination.

[0025] Furthermore, the invention is based on a patient support device with a belt fastening device for fastening safety belts, wherein the belt fastening device has at least one fastening rail and at least one fastening clamp, wherein the at least one fastening clamp has a belt fastening element which, when the at least one fastening clamp is arranged with the at least one fastening rail, is arranged within the at least one fastening rail. This advantageously makes it possible to achieve a high level of patient comfort, since obstruction of the patient due to the belt fastening element can be prevented. Furthermore, this makes it possible to achieve a particularly space-saving and compact arrangement of the belt fastening device.Furthermore, the belt fastening element and also an arrangement of a safety belt on the belt fastening element can be advantageously protected from undesirable impairments and / or damage.

[0026] The advantages of the medical patient support device according to the invention essentially correspond to the advantages of the medical belt fastening device according to the invention, which have been described in detail above. Features, advantages, or alternative embodiments mentioned herein can also be applied to the other claimed subject matter, and vice versa.

[0027] Furthermore, it is proposed that the patient support device comprise a support table that includes the at least one fastening rail, and that the at least one fastening rail is arranged in an edge region of the support table that extends along a longitudinal extent of the support table. This advantageously allows for particularly space-saving fastening at any position along the longitudinal extent of the support table.

[0028] It is further proposed that, in order to release a locking mechanism between the at least one fastening clamp and the at least one fastening rail, a force perpendicular to the longitudinal extent of the at least one fastening rail acts on the at least one fastening clamp from an edge region of the couch table inwards. In this way, a particularly simple release of the at least one fastening clamp can be achieved. Furthermore, in order to release the locking mechanism, medical personnel do not have to reach between the patient and the belt fastening device, in particular the fastening clamp, which both simplifies the workflow for the medical personnel and increases patient comfort. In addition, this can also prevent an undesired release of the locking mechanism by the patient, for example during a medical imaging examination.

[0029] In a further embodiment of the invention, it is proposed that the belt fastening device be compatible with a local magnetic resonance coil device. This allows the belt fastening device to be advantageously integrated into existing systems, in particular magnetic resonance systems. The local magnetic resonance coil devices can, for example, comprise stationary magnetic resonance coil devices, which can preferably be arranged within the fastening rail of the belt fastening device. Furthermore, the local magnetic resonance coil devices can, for example, also be formed by magnetic resonance coil devices that can be positioned on the patient and secured by means of safety belts. In this case, it is also conceivable for the local magnetic resonance coil device to have a fastening rail and / or a fastening clamp.

[0030] Furthermore, the invention is based on a medical imaging device with a patient support device which has a belt fastening device for fastening safety belts, wherein the belt fastening device has at least one fastening rail and at least one fastening clamp, wherein the at least one fastening clamp has a belt fastening element and the belt fastening element is arranged within the at least one fastening rail in a state of the at least one fastening clamp arranged with the at least one fastening rail.

[0031] The advantages of the medical imaging device according to the invention essentially correspond to the advantages of the medical patient support device according to the invention and the advantages of the medical belt fastening device according to the invention, which have been described in detail above. Features, advantages, or alternative embodiments mentioned herein can also be applied to the other claimed subject matter, and vice versa.

[0032] Further advantages, features and details of the invention will become apparent from the embodiment described below and from the drawings.

[0034] In Fig. 1 schematically illustrates a medical imaging device 10. In the present exemplary embodiment, the medical imaging device 10 is formed by a magnetic resonance device. However, the design of the medical imaging device 10 is not limited to a magnetic resonance device. Rather, the medical imaging device 10 can be formed by any medical imaging device deemed appropriate by a person skilled in the art, such as a computed tomography device, a positron emission tomography device, etc.

[0035] The magnetic resonance apparatus comprises a magnet unit 11 with a superconducting main magnet 12 for generating a strong and, in particular, constant main magnetic field 13. Furthermore, the magnetic resonance apparatus has a patient receiving area 14 for receiving a patient 15. In the present exemplary embodiment, the patient receiving area 14 is cylindrical and is surrounded in a circumferential direction by the magnet unit 11. In principle, however, a different design of the patient receiving area 14 is conceivable at any time. The patient 15 can be pushed into the patient receiving area 14 by means of a patient support device 100 of the magnetic resonance apparatus. For this purpose, the patient support device 100 has a table 101 designed to be movable within the patient receiving area 14.

[0036] The magnet unit 11 further comprises a gradient coil unit 16 for generating magnetic field gradients used for spatial encoding during imaging. The gradient coil unit 16 is controlled by a gradient control unit 17 of the magnetic resonance device. The magnet unit 11 further comprises a radio-frequency antenna unit 18 for exciting a polarization that is established in the main magnetic field 13 generated by the main magnet 12. The radio-frequency antenna unit 18 is controlled by a radio-frequency antenna control unit 19 of the magnetic resonance device and radiates radio-frequency magnetic resonance sequences into an examination room, which is essentially formed by a patient receiving area 14 of the magnetic resonance device.

[0037] The magnetic resonance apparatus has a control unit 20 for controlling the main magnet 12, the gradient control unit 17, and the radio-frequency antenna control unit 19. The control unit 20 centrally controls the magnetic resonance apparatus, such as performing a predetermined imaging gradient echo sequence. Furthermore, the control unit 20 includes an evaluation unit (not shown in detail) for evaluating image data. Control information, such as imaging parameters, as well as reconstructed magnetic resonance images, can be displayed to an operator on a display unit 21, for example, on at least one monitor, of the magnetic resonance apparatus. Furthermore, the magnetic resonance apparatus has an input unit 22, by means of which information and / or parameters can be entered by an operator during a measurement process.

[0038] Fig. 2 shows a top view of the patient support device 100. The patient support device 100, in particular the support table 101 of the patient support device 100, has a support area 102 for supporting the patient 15. Furthermore, the support table 101 comprises edge areas 103 that extend in a direction of a longitudinal extent 104 of the support table 101. The support area 102 is arranged between the two edge areas 103. At these edge areas 103 of the support table 101, the patient support device 100 has a belt fastening device 105. By means of the belt fastening device 105, safety belts 106 for securing objects, in particular the patient 15 and / or additional units, are attached to the support table 101.

[0039] For this purpose, the belt fastening device 105 has at least one fastening rail 107 and at least one fastening clamp 108 ( Fig. 2). In the present embodiment, the belt fastening device 105 has two fastening rails 107 and two fastening clips 108. In an alternative embodiment of the invention, the belt fastening device 105 can also have a single fastening clip 108 or more than two fastening clips 108. Furthermore, in an alternative embodiment of the invention, the belt fastening device can also have a single fastening rail 107 or more than two fastening rails 107.

[0040] A first of the two fastening rails 107 is arranged in a first edge region 103, and a second of the two fastening rails 107 is arranged in a second edge region 103 of the bed table 101. The two fastening rails 107 are of identical design. Each of the two fastening rails 107 has an opening 109 and a maximum width 110 ( Fig. 6). The width of the opening 109 is at least 60% of the maximum width 110 of the fastening rails 107. Preferably, the width of the opening 109 is at least 75% of the maximum width 110 and particularly preferably at least 80% of the maximum width 110 of the fastening rails 107, so that a particularly simple insertion of the fastening clips 108 into the fastening rails 107 is achieved.

[0041] The two fastening rails 107 each have a longitudinal extension, wherein the longitudinal extension of the fastening rails 107 is parallel to the longitudinal extension 104 of the bed table 101. In the direction of this longitudinal extension of the fastening rails 107, the opening 109 of the fastening rails 107 always has a constant width ( Fig. 2).

[0042] Furthermore, the two fastening rails 107 each comprise a web-shaped rail element 112, wherein the web-shaped rail elements 112 are arranged in an opening region of the respective fastening rail 107. Each of the two fastening rails 107 has only a single web-shaped rail element 112, wherein the web-shaped rail elements 112 are arranged on only one edge region 113, which runs in the longitudinal extension of the fastening rail 107. The web-shaped rail elements 112 are arranged on the respective fastening rail 107 on an edge region 112 of the respective fastening rail 107 facing away from the storage region 102, so that the opening region of the fastening rails 107 has a one-sided projection ( Fig. 3, 6 to 8). As a result, a concealed area, in particular an area concealed by the web-shaped rail element 112, is present only on one side of the fastening rail 107 within the fastening rail 107. A second edge area, which also runs in the longitudinal extension 111 of the at least one fastening rail 107 and is opposite the edge area 113 with the web-shaped rail element 112 within the at least one fastening rail 107, is formed by a rectilinear continuation of a receiving area of the at least one fastening rail 107.

[0043] The two fastening clamps 108 of the belt fastening device 105 are also of the same design and each have a belt fastening element 114. Furthermore, the two fastening clamps 108 each have a base element 115 on which the belt fastening element 114 is arranged ( Fig. 4 and Fig. 5). The base elements 115 of the two fastening clamps 108 are each U-shaped with two leg elements 116. The belt fastening element 114 of the fastening clamp 108 is arranged between the two leg elements 116 of the U-shaped base elements 115. Preferably, the belt fastening elements 114 are each arranged with a first end region on a first of the two leg elements 116 of the respective base element 115 and with a second end region on a second of the two leg elements 116 of the respective base element 115. The belt fastening elements 114 are web-shaped so that a safety belt 106 of the belt fastening device 105 can be guided around the belt fastening element 114.In addition, the two belt fastening elements 114 are each arranged in a central region on the leg elements 116, so that the safety belt 106 can be safely guided within the fastening clamp 108.

[0044] The two leg elements 116 of a respective base element 115 have a tapered shape 111 on an open side of the base elements 115, so that the respective fastening clamp 108 can be easily locked to one of the two fastening rails 107.

[0045] The fastening clamps 108 further each have an actuating element 117, a securing element 118 and a connecting web 119 ( Fig. 3 to 5 and 7). The actuating elements 117 are each designed for actuation, in particular a release of the fastening clips 108 from the fastening rails 107 and / or a fixation of the fastening clips 108 within the fastening rails 107, by a medical operator.

[0046] The securing elements 118 are each designed to secure the respective fastening clip 108 within the fastening rail 107, so that the fastening clips 108 are protected against unwanted loosening and / or falling out of the fastening rail 107. The connecting webs 119 of the fastening clips 108 are provided for connecting the actuating elements 117 to the base elements 115 within the fastening clips 108. One of the two securing elements 118 is arranged on one of the connecting webs 119 of the fastening clips 108. The actuating element 117 extends in a direction from the belt fastening element 114 toward the connecting web 119, away from the connecting web 119.

[0047] When the respective fastening clamp 108 is arranged with one of the two fastening rails 107, the base elements 115 are arranged at least 70% within the fastening rail 107. Preferably, the base elements 115 are arranged at least 80% within the fastening rail 107 and particularly preferably at least 85% within the fastening rail 107. However, it is particularly advantageous for the base elements 115 to be arranged at least 90% within the fastening rail 107. As a result, the belt fastening elements 14 are also arranged within the fastening rail 107, wherein the belt fastening elements 107 are arranged entirely within the fastening rail 107.In the state in which the respective fastening clamp 108 is arranged with one of the two fastening rails 107, the respective fastening clamp 108 can be arranged movably within the fastening rail 107, in particular movably along the longitudinal extent of the fastening rail 107, or can also be locked with the fastening rail 107.

[0048] When the respective fastening clamp 108 is arranged with the fastening rail 107, the actuating element 17 protrudes from the fastening rail 107, allowing simple and safe actuation by medical personnel. When the fastening clamps 108 are arranged with one of the two fastening rails 107, they are arranged on the patient support table 101 such that the actuating element 117 of the respective fastening clamp 108 faces the edge region 103 of the patient support table 101 in a transverse extension of the patient support table 101, and the belt fastening element 114 faces the support region 102. A grip region of the actuating element 117 faces away from the support region 102 of the patient support device 100 when the respective fastening clamp 108 is arranged with the fastening rail 107.

[0049] In this state of the fastening clamps 108 arranged with one of the two fastening rails 107, the fastening clamps 108 are arranged within the fastening rails 107 in such a way that the securing element 118 of the respective fastening clamp 108 forms a snap-in connection with the web-shaped rail element 112 of the fastening rail 107. This snap-in connection secures the fastening clamps 108 within the fastening rail 107 against falling out of the fastening rail 107. In addition, the fastening clamps 108 are mounted within the fastening rail 107 so as to be movable in the direction of the longitudinal extent of the fastening rails 107, as long as the fastening clamps 108 do not enter a locked state with one of the fastening rails 107. This is particularly advantageous for precise positioning of the fastening clamp 108 for positioning the safety belt 106.

[0050] As soon as a tensile force 122 acts on the belt fastening element 114 due to the tightening of the safety belt 106 by the medical operating personnel, this tensile force 122 causes the fastening clamp 108 to be locked to the fastening rail 107 and to be immovably locked in its position with respect to the direction of the longitudinal extension of the fastening rail 107. This tensile force 122 is in Fig. 2 by an arrow. Due to this tensile force 122, a portion of the fastening clamp 108 opposite the actuating element 117 is moved in the direction of the tensile force 122, which leads to a tilting of the fastening clamp 108 within the fastening rail 107 and thus to a locking.

[0051] To release the locking mechanism between the fastening clamp 108 and the fastening rail 107, a force 123 is exerted on the actuating element 108, for example by the medical personnel. This force 123 is Fig. 8, shown as an arrow, acts in the direction of the transverse extent of the couch table 101, in particular from the edge region 103, in which the fastening rail 107 is arranged, of the couch table 101 in the direction of the storage region 102. In particular, the force 123 acts from the outside in the direction of a center of the couch table 101. This allows easy accessibility of the actuating element 17 for releasing the locking between one of the fastening clamps 108 and one of the fastening rails 107 for the medical operating personnel.

[0052] The belt fastening device 105, in particular the fastening rails 107, is also designed to be compatible with local magnetic resonance coil devices 120. Particularly advantageously, local, stationary magnetic resonance coil devices 120 are arranged within the couch table 101 and serve as a support surface for the patient 15. These stationary magnetic resonance coil devices 120 are fixed within the couch table 101 by means of the fastening rails 107. For this purpose, the local magnetic resonance coil device 120 has fastening elements 121 that are designed to correspond to the fastening rails ( Fig. 2).

[0053] In an alternative embodiment of the invention, the local magnetic resonance coil device 120 can also be formed by a magnetic resonance coil device that can be attached to and / or placed on the patient 15. A magnetic resonance coil device configured in this way can also be designed to be compatible with the belt fastening device 105, in that this magnetic resonance coil device comprises a fastening clamp 108 and / or a fastening rail 107 of the belt fastening device 105.
