Description

TECHNICAL FIELD

[0001] The utility model relates to a patient support table for supporting a patient. BACKGROUND

[0002] A patient support table, also called an examination table, is used in the medical field, in particular for medical imaging and / or examination and / or treatment procedures, such as surgical operations or irradiation. The examination table can thus be associated with an imaging device or another medical device, for example with a computed tomography device, for example.

[0003] The examination table can have a plurality of, in particular three, axes of movement or degrees of freedom of movement. The examination table can be adjusted in height, for example (first degree of freedom). The table structure for accommodating an examination couch for positioning a patient can be designed in such a way that it is adjustable at least along its longitudinal axis (second degree of freedom). The examination couch itself can be adjusted along its longitudinal axis relative to the table structure (third degree of freedom). At least one motor for automatic adjustment along the axis of movement can be provided for each axis of movement. In addition, three further degrees of freedom, in particular three rotational degrees of freedom, can be provided, for example for tilting or inclining.

[0004] In order to move such a couch, a plurality of axes, for example six axes, are required, which are equipped with motors. In order to be able to carry out movements precisely, a position sensor is necessary for each motorized axis. In addition, redundant, identical sensors are used in order to rule out the risk of failure of the couch and to ensure safe irradiation or treatment of the patient.

[0005] Due to the specific requirements, the necessity of a large number of lines which have to be guided to the individual axes arises. For example, in a six-axis couch, there are 22 lines, which have to be laid horizontally over a movement path of approximately 1900 mm.

[0006] Laying the lines requires a considerable amount of space. Due to the limited availability of space, it is not possible to route the axis drives at the superstructure. Therefore, an alternative solution has to be found in order to safely lay the lines and still ensure the effective functioning of the couch.

[0007] It is also very important to keep the climbing height for the patient as small as possible. This means that the design of the couch has to be adapted accordingly in order to be able to realize a comfortable and easy-to-reach climb for the patient. Here, both mechanical and electrical aspects should be carefully considered in order to ensure optimal functionality and safety.

[0008] In order to obtain a line quantity in such a bed, a space-saving bellows solution has hitherto been used as a covering device for the shaft for movement. However, the solution has some disadvantages. On the one hand, cleaning of such a bellows solution is difficult. Furthermore, the bellows solution tends to crack due to environmental influences because of its certain elasticity, and material residues can detach during the product service life. Furthermore, the bellows solution is significantly less robust with respect to external influences compared to other covering devices.

[0009] German utility model DE 10 2016 004 101 U relates to a medical examination or treatment apparatus comprising a C-arm with a radiation source and a radiation receiver and one or more power supply and / or cooling lines for the radiation source and / or the radiation receiver, wherein the C-arm is movably arranged on a holding device along its circumference. Utility model content

[0010] The object underlying the present utility model is therefore to propose a patient support device with a horizontal adjustment device which allows guiding of lines such that it is also possible to move and / or move the examination bed in a plurality of degrees of freedom over a greater range. In particular, the object of the present utility model is to support the lines safely and with low wear in all states (patient climb, patient treatment).

[0011] In order to achieve the object, a patient support table for supporting a patient is proposed according to the present utility model. Advantageous design solutions result from the present utility model.

[0012] Irrespective of the grammatical gender of the specific terms, persons with a male, female gender identity are included.

[0013] The patient support table according to the present utility model constitutes a patient support table for supporting a patient. The patient support table comprises:

[0014] - a lying plate on which a patient can be supported, wherein a climb state can be assumed by the lying plate in a first height and an operating state in a height greater than the first height,

[0015] - a carrying device carrying the lying plate,

[0016] - a horizontal adjustment device with a first drive mechanism for horizontally moving the lying plate in at least one direction,

[0017] - a vertical adjustment device with a second drive mechanism for height adjustment of the lying plate and / or for switching between the climb state and the operating state,

[0018] - line guiding device, wherein the line guiding device constitutes a housing for one or more supply and / or control lines,

[0019] - an intermediate section arranged between the lying plate and the vertical adjustment device,

[0020] - a support device, wherein the support device is arranged in the intermediate section, wherein the support device comprises a support section pivotable about a pivot axis, wherein the support section is in a first position in the operating state and the support section is in a second position in the climbing state, wherein

[0021] the support section is in the second position at a height above the pivot axis and / or the support section is in the second position at a height below the pivot axis, wherein the support device is designed to entrain and / or support the line guiding device when switching from the operating state into the climbing state and / or from the first position into the second position, wherein the line guiding device is lying and / or supported in the support section in the second position and / or in the climbing state.

[0022] The patient support can constitute a support for supporting a patient during irradiation. The patient support in particular constitutes a support for supporting a patient during a surgical operation. In particular, the patient support constitutes a support for supporting a patient during medical imaging in an MRT, CT or other imaging device.

[0023] The lying plate is technically designed such that it is suitable for medical imaging and / or irradiation. The lying plate is constituted by a robust material which not only has a high stability but also a good penetration for medical rays. The plate can position a patient safely and comfortably in order to achieve optimal imaging results or to perform precise irradiation. The plate preferably has a smooth surface in order to enable simple cleaning and disinfection. Furthermore, the lying plate can be equipped with specific fastening points in order to safely fix a patient during imaging or irradiation and to minimize movements.

[0024] The patient support, in particular the lying plate, can assume a climbing state and an operating state. In the climbing state, the lying plate is at a first height. The first height can form a minimum height and / or a lowest position of the lying plate. In the operating state, the lying plate is at a height which is greater than the first height, in particular the lying plate is at a height which is at least 50 cm, preferably at least 100 cm above the ground. The first height in particular forms a climbing height, wherein a patient can climb onto, sit onto and / or lie onto the lying plate when the lying plate is arranged at the climbing height.

[0025] As is known in principle, the horizontal adjustment device preferably has a horizontal mechanical device with a cantilever unit movable relative to the lying plate and the bearing device, which at least partially bears the lying plate. Bearing here is to be understood essentially in the sense of a mechanical connection of the lying plate arranged above the cantilever unit; the load of the lying plate and components carried by it is essentially absorbed by the guide device of the patient support device.

[0026] The first drive mechanism can comprise an electric motor, a mechanical system, a pneumatic and / or a hydraulic drive. It is particularly preferred that the first drive mechanism forms and / or comprises an electric motor. The first drive mechanism can preferably be controlled via an operating element, which enables the medical staff to achieve an exact and simple positioning of the patient.

[0027] A vertical adjustment device is used in order to adjust the height of the lying plate. The vertical adjustment device enables the bed to be adjusted to an ergonomic working height and to position the patient comfortably. Additionally, the vertical adjustment device can be used in order to switch between the climbing state and the operating state.

[0028] The vertical adjustment device can have a second drive mechanism, which enables the height adjustment of the lying plate. Examples of such drive mechanisms are:

[0029] Electric linear drive: An electric linear drive uses an electric motor and a screw spindle in order to control the vertical movement of the lying plate. The electric linear drive provides an exact and gentle height adjustment, which can be easily controlled via an operating element.

[0030] Electric drive: An electric drive for driving and / or operating a scissor base. A scissor base comprises in particular two intersecting struts, which are pivotably connected in a common point about a common axis.

[0031] Hydraulic system: In addition to the horizontal movement, a hydraulic system can also be used for the vertical adjustment of the lying plate. The height of the lying plate can be adjusted by pumping or releasing the hydraulic pressure.

[0032] Pneumatic system: Similar to when moving horizontally, a pneumatic drive can also be used for the vertical adjustment. The lying plate can be positioned in the desired height by controlling the air pressure.

[0033] The drive mechanisms enable a flexible and exact height adjustment of the lying plate in order to meet the requirements of medical care. The drive mechanisms provide comfort for the patient and facilitate the work of the medical staff.

[0034] The line guiding device is preferably integrated into the patient support table, in particular the line guiding device is arranged in a receiving space and / or is covered by a housing. The line guiding device constitutes a line for accommodating power supply and / or control lines. The line guiding device serves for orderly and safe guiding of the lines in order to avoid tripping, entanglement and not to limit or endanger the movement of components.

[0035] The line guiding device is preferably designed such that it can accommodate one or more power supply and / or control lines. This can be, for example, an electrical cable for driving the system, a data cable, a medical gas line or a control cable. The line guiding device comprises and / or forms, in particular, a channel, a track or a cable carrier. In an alternative embodiment, the line guiding device extends from the floor area and / or the first level to the second level and / or the lying plate. In particular, the line guiding device extends between the first drive mechanism and the second drive mechanism.

[0036] The intermediate section arranged between the lying plate and the vertical adjustment device in the examination table plays an important role in the adjustment and flexibility of the examination table. The intermediate section is between the main part of the lying plate on which the patient lies and the vertical adjustment device which is responsible for the height adjustment. The intermediate section can be, in particular, part of a frame or support structure. The intermediate section can form, in particular, one section of a carrier device or comprise a carrier device.

[0037] The support device is in the intermediate section arranged between the lying plate and the vertical adjustment device. The support device is preferably arranged in the intermediate section, in particular at the frame. The support device is, for example, connected to the intermediate section, in particular the frame, form-fittingly, frictionally, force- fittingly and / or materially. The support device comprises a support section which can be pivoted about a pivot axis. Furthermore, the support device preferably comprises a fastening section for fastening and / or connecting to the intermediate section, in particular the frame and / or the housing section.

[0038] The support section can be in a first position in the operating state and in a second position in the climbing state. In the second position of the support section, the support section is at a height above the pivot axis. In the first position of the support section, the support section is positioned at a height less than or equal to the pivot axis.

[0039] The support device is designed such that it at least partially carries and / or supports the line guide device when switching into the climbing state and / or from the first position into the second position. The line guide device can be supported on the support section or by the support section in the second position and / or in the climbing state. In other words, the line guide device is partially lifted, in particular to the height of the second position, when switching into the climbing state and / or when switching from the first position into the second position. When switching into the first state and / or the operating state, the support section is moved downwards and / or removed or moved away as a support for the line guide device, so that the line guide device is no longer lifted or supported by the support section in the operating state.

[0040] The utility model can realize that one section of the line guide device is lifted in the climbing state and is not lifted in the operating state, so that the section of the line guide device has a different orientation, position, height and / or course in the climbing state than in the operating state.

[0041] It is particularly preferred that the support device forms and / or comprises a hinge. The support device and / or the hinge is based on a hinging mechanism. The hinge is in particular composed of two sections, preferably two plates or elements, which are connected to each other and can be moved about an axis. One section of the hinge comprises and / or forms the support section. The other section is preferably connected to the intermediate section, i.e. the frame and / or the housing, in particular in a movement-resistant, position-secure, force-fitting, form-fitting and / or material-fitting manner. The two sections, i.e. elements and / or plates, are also referred to as wings, in particular. The components of the hinge are movable components, which are preferably made of metal, plastic or wood.

[0042] It is particularly preferred that the support device, in particular the hinge, comprises a reset device. The reset device is designed such that it guides the support section back into its initial position as soon as a manipulation force falls below the reset force of the reset device. The reset device serves to reset the support section to its initial position, preferably the second position, after it has been deflected, preferably into the second position, due to an external force or movement. The manipulation force, for example, results from moving the lying plate into the climbing position, for example the support section lying down on the housing or a fixed element, for example a pin.

[0043] The exact design of the reset device varies from case to case. The reset device comprises a reset spring, wherein the reset force forms the spring tension of the reset spring. Preferably, the design is implemented by means of a spring. The spring can be a tension spring or a pressure spring and is designed in such a way that it generates the reset force. The reset force counteracts the deflection of the support section and ensures that the support section returns into its initial position. When a manipulation force acts on the support section and the manipulation force is lower than the reset force of the reset device, a reset effect occurs. That is to say, the reset device is activated and resets the support section into its initial position by means of the generated reset force.

[0044] The support device preferably comprises a pin-shaped, column-shaped and / or peg-shaped manipulation element. The manipulation element is designed in such a way that it initiates the switching of the support section from the first position into the second position when the height of the lying board can be adjusted and is below a certain minimum height.

[0045] In the described design, a pin-shaped, column-shaped and / or peg-shaped manipulation element is used to enable the switching of the support section of the hinge from the first position into the second position. The movement occurs when the lying board is transitioned from the operating state into the climbing state and is below the minimum height here.

[0046] The manipulation element can have different shapes, for example with a pin or with a peg-shaped portion. The exact shape is related to the specific construction and requirements of the support device.

[0047] When the lying board is below a certain minimum height, the manipulation element acts on the support section, the wing and / or the line guide. For example, the support section lies on the manipulation element and / or supports the manipulation element when below the minimum height.

[0048] In a preferred design of the utility model, the line guide forms and / or comprises an energy chain. An energy chain, also called cable chain or energy guide chain, is a mechanical device for safely guiding cables, lines or hoses and protecting them from external influences such as abrasion, contamination or damage.

[0049] The energy chain consists of a series of segments that are connected to each other and form a flexible chain. The segments can be made of plastic or metal, wherein plastic is generally preferred due to its low friction and high wear resistance. Each segment has a specific shape that enables the segments to be spliced into each other and at the same time moved in different directions.

[0050] The energy chain comprises a cavity structure or a channel in which cables, lines or hoses can be placed. The cables, lines or hoses are safely guided within the energy chain and protected from external influences. Thus, the energy chain provides an ordered and protected line guide.

[0051] One main advantage of the energy chain is its flexibility. The segments of the chain are designed in such a way that they can move and adapt to movements relative to one another. Thereby, the energy chain can be bent in at least one direction without the cables or lines contained therein being kinked or damaged. The flexibility of the energy chain enables flexible movement guidance and prevents cable breakage or line interference.

[0052] The line guide device comprises, as described, in particular a bearing segment. In the climbing state, the bearing segment rests on or lies flat on the support segment. In one alternative design, the line guide device has a lower bending stiffness in the bearing segment than outside the bearing segment. Preferably, the line guide device can be bent or deformed positively as well as negatively in the bearing segment, whereas the line guide device can only be bent positively or negatively outside.

[0053] The bearing segment of the line guide device is the area in which the energy chain rests on or is supported at the support segment. The support segment can be, for example, a structure or a component on which the energy chain is placed or supported. The segment ensures stable bearing or support of the line guide device in the climbing state.

[0054] The line guide device can only be bent positively or negatively outside the bearing segment. This means that the line guide device can be bent either outwardly (positively) or inwardly (negatively), but not in both directions. In general, a specific design of the line guide device can be achieved.

[0055] Preferably, the patient support table is characterized in that it comprises a vertical cover device. The vertical cover device is below the intermediate segment and / or at least partially surrounds the vertical adjustment device. The support segment and / or the bearing segment are arranged in the operating state in a structure space formed by the vertical cover device. In the climbing state, the support segment and / or the bearing segment are outside the structure space formed by the vertical cover device. The vertical cover device can consist of plastic, metal or other suitable materials and serves to protect and surround the support segment and / or the bearing segment.

[0056] In the operating state, the support segment and / or the bearing segment are inside the structure space formed by the vertical cover device. The structure space provides protection and limits the movement of the energy chain. The vertical cover device ensures that the line guide device remains inside the defined space and is protected from external influences such as contamination, dust or impacts.

[0057] In the climbing state, the support section and / or the bearing section are outside the structural space delimited by the vertical covering device. This enables the arrangement of further components of the patient support table. Due to the lower height in the climbing state, the structural space delimited by the vertical covering device is smaller than in the operating state, so that a smaller space is provided in the structural space for accommodating components of the patient support table. By the utility model, the line guide device is arranged outside the structural space at least in the region of the support section.

[0058] The vertical covering device described is preferably characterized by a telescoping construction and / or comprises a plurality of covering elements which can be pushed into one another.

[0059] In the telescoping vertical covering device, a plurality of covering elements are arranged one above the other, in particular in the operating state, and can be pushed into one another, in particular in the climbing state. The telescoping construction enables the vertical covering device to be adapted to different height adjustments or climbing states. When the lying plate is in a lower position, the covering elements are pushed together and form a compact protection. When a height adjustment is made or in the operating state, the covering elements are pushed apart from one another in order to cover a greater height.

[0060] The covering elements which can be pushed into one another provide a flexible adaptation to the respective requirements. The covering elements allow the covering area of the vertical covering device to be enlarged or reduced depending on the height adjustment. This ensures optimum protection and prevents dirt, dust or other external influences from penetrating.

[0061] Preferably, the patient support table comprises a foot section and an upper structure section. The foot section is below the intermediate section. The line guide device extends from the foot section into the intermediate section and can further lead to the horizontal adjustment device and / or the lying plate.

[0062] The foot section is a lower part which is usually near the floor or base of the patient support table. The foot section can contain different fastening elements or holding devices in order to hold the line guide device in place. The intermediate section is above the foot section and forms a connection between the foot section and the upper structure section of the line guide device. The line guide device can continue from the intermediate section to the horizontal adjustment device and / or the lying plate. The horizontal adjustment device enables the lying plate to be moved in the horizontal direction, in particular, the line guide device can follow said movement.

[0063] The horizontal adjustment device is preferably designed in such a way that it can move the lying plate in the longitudinal direction by at least 1700 mm. This means that the energy chain can achieve a horizontal degree of freedom of movement of at least 1700 mm in the longitudinal direction of the lying plate. The horizontal adjustment device can comprise different mechanisms or drive systems in order to be able to achieve the movement of the lying plate. This can be achieved, for example, by a motor-driven linear shaft, a rack or pinion mechanism, a slide rail or other corresponding configurations.

[0064] The described vertical adjustment device preferably comprises a second drive mechanism which is arranged at a height which is less than or equal to the height of the intermediate section. In particular, the first drive unit and the first drive mechanism and the second drive unit and the second drive mechanism can be used synonymously. The second drive mechanism is part of the vertical adjustment device. The drive mechanism can be, for example, a motor, a hydraulic or pneumatic system or other suitable mechanisms which provide the required force and control for the vertical movement. The arrangement of the second drive mechanism at a height which is less than or equal to the height of the intermediate section has the advantage that a compact construction can be achieved. By placing the drive mechanism near the intermediate section, the space requirement can be reduced. This facilitates the integration of the vertical adjustment device into the overall construction of the machine or facility and enables an efficient use of space.

[0065] Preferably, the first drive mechanism and / or the second drive mechanism comprises a sensor module and a redundant sensor module for each movement axis. The sensor module is a sensor or control device for detecting, controlling and monitoring the movement and position of the drive mechanism. The sensor module can be, for example, an incremental or absolute encoder, a potentiometer or a magnetic Hall effect sensor. The redundant sensor module is an additional sensor module which works in a manner independent of the first sensor module and fulfils the same function. The sensor modules are used in order to improve the fault safety and reliability of the position determination and movement detection. If one of the sensor modules fails or is disturbed, the redundant sensor module can also provide precise measurements and data. BRIEF DESCRIPTION OF DRAWINGS

[0066] Further advantages, effects and design proposals result from the drawings and their description. Shown here is:

[0072] Figure 1 An external view of a patient support table 1 according to the utility model is shown. The patient support table 1 comprises a carrying device for carrying a lying plate 2. In the described embodiment, a carrying section is provided in an intermediate section 3. The intermediate section 3, in particular the carrying section, can be part of a frame, also called carrying frame. For the sake of simplicity, the lying plate 2 is shown in the Figure 2 without a cushion in the figures, but can optionally comprise a cushion.

[0073] The patient support table 1 is shown schematically in cross section in Figure 2 . There it can first be seen that the patient support table 1 has a central vertical adjustment device 4 and a horizontal adjustment device 5 associated with the lying plate 2, which is currently only roughly indicated.

[0074] The vertical adjustment device 4 comprises a lifting mechanism 6, which connects the intermediate section 3 and the ground or rather the lower section. As indicated in Figure 2 , the lifting mechanism 6 has a scissor mechanism. The lifting mechanism 6 is connected with a slide 8 guided on a main shaft, wherein the main shaft can be rotated by means of an electrically driven second drive 9, here an electric motor. The main shaft can alternatively also act vertically upwards in a preferred manner and is connected via a lever with the scissor mechanism. The scissor mechanism of the lifting mechanism 6 is here made of aluminum or glass fiber reinforced plastic (GFK).

[0075] The horizontal adjustment device 5 also comprises an electric motor as an electrically driven first drive 10.

[0076] Figure 3a A partial view of the patient support table 1 is shown, wherein the patient support table 1 or rather the lying plate 2 is in an operating state. The partial view shows a part of the intermediate section 3, of the horizontal adjustment device 5, of the lying plate 2 and of a vertical covering device 11. The vertical covering device 11 comprises a plurality of covering elements 11a. The covering elements 11a are essentially uniform and / or increase or decrease in size while maintaining the scale. The size or rather the volume of the covering elements 11a decreases from top to bottom.

[0077] The lying plate 2 is in a running state. The running state is characterized, inter alia, in that the lying plate 2 is in an elevated position above the climbing height. The elevated position is, for example, the height of the lying plate 2 during treatment, irradiation, imaging or surgery. Furthermore, the running state can be characterized by a horizontal position and / or position of the examination couch which is not a rest position. The rest position corresponds, for example, to the lying plate 2 not being moved in the horizontal direction. Furthermore, a section of the line guide 12 is shown, which in the section shown extends essentially horizontally.

[0078] Figure 3b A cross section of the patient support 1 in Figure 3a is shown. In the cross section the course of the line guide 12, which is otherwise covered by the vertical cover 11, can be seen. Here, the line guide 12 extends in the interior partly in a construction space 13 which is defined by the uppermost cover element 11a.

[0079] The support device 14 comprises a support section 15 and a second section 16, which is also referred to as a fastening section. The support device 14 forms a hinge. The support device 14 comprises a pivot axis 17. The second section 16 is connected, inter alia, with the intermediate section, for example screwed. Thus, the support device or the second section is connected with the intermediate section 4 against movement. The support section 15 can be pivoted about the pivot axis 17.

[0080] The support section 15 is in a first position. In the first position, the support section 15 is below the pivot axis. In other words, in the first position the line guide is not lying on the support section 15.

[0081] Figure 4a A partial view of the patient support 1 in Figure 3a is shown, in which the patient support 1 or the lying plate 2 is in a climbing state.

[0082] The lying plate 2 is in a climbing state. The climbing state is characterized, inter alia, in that the lying plate 2 is in an elevated position below the climbing height. In particular, similar to the case of a telescopic pole, the cover elements 11a of the vertical cover 11 are at least partially arranged in one another. The construction space 13 defined by the vertical cover 11 or the cover elements 11a is smaller in the climbing state than in the running state. Furthermore, the climbing state can be characterized by a horizontal position and / or position of the examination couch in a rest position. The rest position corresponds, for example, to the lying plate 2 not being moved in the horizontal direction.

[0083] In the climbing state, the visible section of the line guide 12 does not extend horizontally. The line guide 12 is arranged more upwardly or closer to the lying board 2 in the vicinity of the vertical covering device, i.e. at a greater distance from the vertical covering device. If the line guide 12 were to continue to extend only horizontally, it would collide with the uppermost covering element 12 and / or the intermediate section 4.

[0084] Figure 4b A cross section of the patient support 1 in Figure 4a is shown. In the cross section, the course of the line guide 12, which is otherwise concealed by the vertical covering device 11, can be seen. Here, the line guide 12 extends substantially outside the construction space 13 defined by the uppermost covering element 11a.

[0085] In order to avoid a collision between the line guide and the vertical covering device 11 or the intermediate section 4, the support section 16 of the support device 14 is switched into a second position in the climbing state. In the second position, the support section 16 is above the pivot axis. Furthermore, in the climbing state or in the second position, the line guide lies on the support section 16. The support section 16 in the second position supports the line guide 12 such that it is higher than the height of the pivot axis 13 and / or outside the construction space in this region, also referred to as support section 17.

[0086] Figure 5 A line guide 12 in the form of a flexible chain is shown. The line guide 12 is composed of a large number of individual chain links 12a, which are composed, for example, of a plastic piece which is rectangular in cross section. The individual chain links 12a are connected to one another in succession and can be pivoted relative to one another about corresponding pivot axes 12b, such that a defined movement or flexibility results, as is indicated by the two arrows in Figure 5 . Thus, the chain links 12a can be pivoted relative to one another, such that the flexible chain can be wound up and stretched to a certain extent. The movement of the chain links 12a relative to one another is only possible about the pivot axes 12b, whereas no movement is possible in other spatial directions or planes. This results in the flexibility of the flexible chain only being present in a defined plane.

[0087] The line guide 12, in particular the flexible chain, can comprise a flexible sheath 12c which completely surrounds the flexible chain and is composed, for example, of a suitable plastic film. By means of the sheath 12c, a closed surface is formed, which enables easy cleaning.
