Description

Technical Field

[0001] The utility model relates to a patient supporting table for supporting a patient. Background Art

[0002] Patient support tables, also called examination tables, are used in the medical field, in particular for medical imaging and / or for examination and / or treatment procedures, such as surgery or radiotherapy. That is, the examination table can be associated with an imaging device or other medical equipment, such as a computed tomography device.

[0003] The examination table can have multiple, in particular three, axes of motion or degrees of freedom. For example, the height of the examination table can be adjusted (first degree of freedom). The table top structure for accommodating the examination bed for positioning the patient can be designed to be adjustable at least along its longitudinal axis (second degree of freedom). The examination bed itself can be adjusted relative to the table top structure along its longitudinal axis (third degree of freedom). At least one motor for automatic adjustment along the axis of motion can be provided for each axis of motion. In addition, three further degrees of freedom, in particular three rotational degrees of freedom, can be provided, for example for tilting or tilting.

[0004] To move such a bed, multiple axes, for example, six, equipped with motors are required. To ensure precise movement, position sensors are required for each motorized axis. Furthermore, redundant, identical sensors are used to eliminate the risk of bed failure and ensure safe radiation or treatment for patients.

[0005] Due to these specific requirements, a large number of pipelines are required, which must be led to each axis. For example, in a six-axis bed, there are, for example, 22 pipelines, which must be laid horizontally on a travel distance of approximately 1900 mm.

[0006] The laying of the lines requires a considerable amount of space. Due to the limited space available, it was not possible to lay the cables for the shaft drives on the superstructure. Therefore, an alternative solution had to be found to lay the lines safely while still ensuring the effective function of the bed.

[0007] It's also crucial to keep the patient's entry height as low as possible. This means the bed's configuration must be adapted to ensure comfortable and easy access for the patient. Mechanical and electrical aspects require careful consideration to ensure optimal functionality and safety.

[0008] In order to accommodate the required amount of lines in such a bed, space-saving bellows solutions have been used to date as covers for the moving shafts. However, these solutions have several disadvantages. On the one hand, such bellows solutions are difficult to clean. Furthermore, due to their certain elasticity, they are susceptible to cracking due to environmental influences, and material residues may become detached during the service life of the product. Furthermore, these bellows solutions are significantly less robust against external influences than other coverings.

[0009] Current state-of-the-art designs present significant challenges with regard to the cleanability and hygienic design of the shaft. These designs allow dripping liquids to penetrate the shaft, potentially coming into contact with essential drive components and electromechanical components such as motors and sensors. This can potentially damage the associated components.

[0010] Insufficient cleanability of the shaft means that proper cleaning and disinfection becomes difficult or even impossible. This can lead to a buildup of dirt, deposits and bacteria, which compromises the hygiene of the entire system.

[0011] German utility model DE 10 2016 004 101U relates to a medical examination or treatment device comprising a C-arm having a radiation source and a radiation receiver, and one or more supply lines and / or cooling lines for the radiation source and / or the radiation receiver, wherein the C-arm is arranged movably along its circumference on a holding device. Utility Model Content

[0012] The object of the present invention is therefore to provide a patient support table with a vertical adjustment and a horizontal adjustment which allows safe and space-saving routing of lines, is easy to clean and meets hygiene standards in the medical field.

[0013] According to the present invention, in order to achieve this object, a patient support table for supporting a patient is proposed. Advantageous designs can be seen from the description and the drawings.

[0014] Regardless of the grammatical part of speech of a particular term, both male and female individuals are included.

[0015] The patient support table according to the present invention is configured to support a patient. The patient support table comprises: a lying plate on which the patient can rest,

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

[0017] a vertical adjustment device for adjusting the height of the reclining plate, said vertical adjustment device comprising a second drive mechanism,

[0018] - a driving module movable and / or positionable in a longitudinal direction,

[0019] a guide section having at least one guide element, wherein the guide element extends in the longitudinal direction and is designed to guide the entrainment module,

[0020] A line guide, wherein the line guide is designed to accommodate one or more supply and / or control lines, wherein the line guide runs and / or is arranged in an S-shaped manner in the guide section.

[0021] The patient support table can be configured to support a patient during radiation therapy. The patient support table is particularly configured to support a patient during surgery. In particular, the patient support table is configured to support a patient during medical imaging in an MRI system, CT or other imaging device.

[0022] The bed is technically designed to be suitable for medical imaging and / or radiation therapy. It is based on a robust material that offers both high stability and good permeability to medical radiation. The bed allows for secure and comfortable positioning of the patient for optimal imaging results or precise radiation therapy. The bed preferably has a smooth surface for easy cleaning and disinfection. Furthermore, the bed can be equipped with dedicated fixing points to securely secure the patient and minimize movement during imaging or radiation therapy.

[0023] The patient support platform, in particular the bed support, can assume a bed entry position and an operating position. In the bed entry position, the bed support is at a first height. The first height can constitute the minimum height and / or the lowest position of the bed support. In the operating position, the bed support is at a height greater than the first height, in particular, at least 50 cm, preferably at least 100 cm above the ground. The first height constitutes the bed entry height, wherein when the bed support is at the bed entry height, the patient can step onto the bed support and sit and / or lie down.

[0024] As is generally known, the horizontal adjustment device preferably comprises a horizontal mechanism with an arm unit that is movable relative to a fixed and / or stationary frame and / or support, in particular a bed, and that at least partially supports the bed. Support is understood primarily in terms of the mechanical connection to the bed arranged above the arm unit. The loads on the bed and the components supported thereby are primarily absorbed by the guides of the patient support device.

[0025] The first drive mechanism can include an electric motor, a mechanical system, a pneumatic and / or hydraulic drive. Particularly preferably, the first drive mechanism is formed and / or includes an electric motor. The first drive mechanism is preferably controllable via an operating element that enables medical personnel to precisely and easily position the patient.

[0026] The vertical adjustment device is used to adjust the height of the reclining board. It allows the bed to be set to an ergonomic working height and comfortably position the patient. Additionally, the vertical adjustment device can be used to switch between a bed-entering state and an operating state.

[0027] The vertical adjustment device can have a second drive mechanism, which enables the height adjustment of the lying plate. Examples of such a drive mechanism are:

[0028] Electric linear drive: The electric linear drive uses an electric motor and a lead screw to control the vertical movement of the reclining board. The electric linear drive provides precise and smooth height adjustment that can be easily controlled via an operating element.

[0029] Electric drive: An electric drive for driving and / or operating the scissor foot. The scissor foot comprises, in particular, two cross-braces which are connected in a manner such that they can pivot about a common axis at a common point.

[0030] Hydraulic system: In addition to horizontal movement, the hydraulic system can also be used for vertical adjustment of the deck. By pumping or releasing hydraulic pressure, the height of the deck can be adjusted.

[0031] Pneumatic system: Similar to horizontal movement, pneumatic drives can also be used for vertical adjustment. By controlling the air pressure, the deck can be positioned at the desired height.

[0032] These drive mechanisms enable flexible and precise adjustment of the height of the bed to meet the requirements of medical care, provide comfort for the patient and simplify the work of the medical staff.

[0033] The driving module is preferably movable, travelable and / or positionable along the longitudinal direction. The longitudinal direction is particularly located in a horizontal plane. Preferably, the reclining board has a head section for positioning the patient's head and a foot section for positioning the patient's feet, wherein the head section and the foot section are spaced apart in the longitudinal direction. The driving module is particularly movable forward and backward along the longitudinal direction. In particular, the driving module can include a drive mechanism, a sensor and / or a controller and / or be connected to the drive mechanism, the sensor and / or the controller so that the driving module can be moved and / or positioned in a controlled manner along a predefined path. The driving module is particularly configured to drive the reclining board, the vertical adjustment device and / or the horizontal adjustment device during its movement along the longitudinal direction. For example, the reclining board, the vertical adjustment device and / or the horizontal adjustment device are arranged on and / or above the driving module.

[0034] The guide section is preferably arranged, can be arranged, and / or is designed to be arranged on the ground and / or floor. The guide section includes at least one, preferably at least two or exactly two, and in particular at least three guide elements. The guide elements can be designed, for example, as rails, in particular guide rails. The guide elements, in particular at least two guide elements, extend in the longitudinal direction. In particular, in the case of at least two guide elements, the at least two guide elements, preferably all guide elements, are oriented in the same direction and / or are parallel. One or more of the guide elements are particularly designed to guide the entrained module and / or as a rail for the entrained module. In particular, the mobility and / or positionability of the entrained module in the longitudinal direction is limited by the longitudinal extension and / or length of the one or more guide elements. The guide elements are preferably designed as hollow bodies. Alternatively, the guide elements can be designed as solid or solid bodies. The guide elements are preferably made of metal, in particular light metal or steel. Alternatively and / or in addition, the guide elements can be based on composite materials or plastic.

[0035] The line guide is designed to accommodate supply and / or control lines. Such a line guide ensures that the lines are neatly and safely guided, avoiding tripping and tangling, and without restricting or endangering the movement of components. In particular, the line guide is designed to protect the accommodated lines from abrasion, cable breakage, and / or wear. The line guide preferably has a hollow profile. In particular, the line guide is designed to be flexible and / or bendable in at least one dimension. The line guide can be based on a plurality of links, such as chain links or ring segments, which are movable and / or tiltable relative to one another about at least one axis.

[0036] The line guide is preferably designed such that it can accommodate one or more supply lines and / or control lines. This can include, for example, electrical cables, data cables, medical gas lines or control cables for a drive system. The line guide in particular comprises and / or forms a channel, a rail or a cable carrier. The line guide extends and / or runs at least partially in the guide section. The line guide can also run outside the guide section, for example in or towards the horizontal adjustment device and / or vertical adjustment device. For example, the line guide is connected to and / or passes through Guide section, vertical adjustment device and / or horizontal adjustment device.

[0037] According to the present invention, the pipeline guide extends in an S-shaped manner in the guide section. The S-shape is understood to be an arc-shaped extension and / or an arc-shaped curve that is reminiscent of the letter "S". Preferably, the S-shaped extension of the pipeline guide preferably describes a symmetrical curve. In addition, the S-shaped extension preferably describes a curve with a turning point (curvature change), wherein the turning point is particularly preferably located in the middle section of the S-shape. In particular, the S-shape can be understood as a meandering extension and / or can be described as a Bezier curve. Alternatively, the pipeline guide has an extended S-shape in the guide section, the extended S-shape having, for example, more than two turns.

[0038] The present invention enables a particularly space-saving pipeline guide in the guide section, especially in the floor area, and adapts to other components and the environment. This also makes it possible to implement alternative travel paths or pipelines / line guides. The present invention also offers other advantages. It achieves high cycle times, can be implemented within an acceptable structural space, and ensures constant background noise and a high degree of smooth operation. High reliability minimizes downtimes, and low product costs offer economic advantages. A robust design is ensured by using primarily statically laid pipelines for patient monitoring and the shaft drive. Simple installation reduces installation time, and the low number of components also contributes to a more robust design. Overall, the present invention is an attractive solution for a variety of applications. Guiding the pipelines in a closed profile ensures a high level of hygiene. Any escaping liquid does not reach the interior of the horizontal shaft, allowing for optimal cleaning of the shaft.

[0039] Optionally, the guide section includes two deflection modules spaced apart in the longitudinal direction. Preferably, the deflection modules are located at two ends of one or more guide elements spaced apart in the longitudinal direction. In particular, the guide section includes two parallel guide elements, each of which includes and / or is associated with a deflection module, wherein the deflection modules are spaced apart in the longitudinal direction or disposed at opposite ends. The deflection modules, for example, include or form deflection rollers. The deflection rollers can be configured to guide a pipeline guide, for example, including guide grooves for accommodating the pipeline guide. In particular, the deflection modules are configured to deflect the pipeline guide within a fixed bending radius. In particular, the deflection modules deflect the pipeline guide within a minimum bending radius so that the deflection module does not cause cable breakage and / or pipeline wear. The deflection modules are preferably configured to deflect the pipeline guide by at least 90 degrees, in particular at least 120 degrees, and particularly preferably at least 180 degrees. The pipeline guide extends around the deflection modules within the guide section and / or within the S-shaped extension.

The pipeline guide preferably extends in the guide channel or the guide channel segment before the first steering module, between the two steering modules and / or after the second steering module.

[0041] According to an alternative design, the guide section includes at least two guide elements oriented identically in the longitudinal direction. The guide elements are designed, for example, as guide rails. The pipeline guide extends at least partially between the two guide elements, in particular in a guide section channel located between the two guide elements. The guide elements thus protect the pipeline guide from lateral trampling, force exposure, and / or contamination.

[0042] The guide section preferably has a closed profile, in particular a profile that is closed upward and / or laterally. In particular, the guide section channel is closed upward and / or laterally and / or in the longitudinal direction, so that no contaminants, liquids and / or external forces can enter or act on the guide section channel and / or the line guide. In particular, the guide section and / or the guide section channel is covered, closed and / or delimited upward by a cover.

[0044] It is preferably proposed that one end of the S-shaped pipeline guide is mechanically connected to the driving module. In particular, the driving module has at least one, preferably at least two, side segments. The side segments are preferably used to couple with and / or engage with the guide segments, in particular the guide elements. For example, the guide elements and the side segments form interfaces and mating interfaces. The guide elements and the side segments constitute, in particular, a mechanical, form-fitting and / or anti-loss connection. The pipeline guide is preferably connected to the driving module at at least one, preferably at at least two, side segments. In this case, it is preferably proposed that the driving module drags the pipeline guide, in particular at the connected and / or connected locations, during its movement in the longitudinal direction.

[0052] Figure 1 The figure shows an exterior view of a patient support table 1 according to the present invention. The patient support table 1 includes a carrier section 2 for supporting a bed. The bed itself is not shown here to allow the carrier section to be seen. The bed is configured to support a patient during surgery, medical imaging, and / or radiation therapy.

[0053] The patient support table 1 comprises a central vertical adjustment device 3 and a horizontal adjustment device 4 , which are only roughly indicated here.

[0054] The vertical adjustment device 3 includes a lifting mechanism, which is covered by a cover. The vertical adjustment device 5 is mechanically connected to the drive module 9. When the drive module 9 moves in the longitudinal direction L, the lifting mechanism and / or the section of the patient support table 1 located thereon are driven. The vertical adjustment device 3 and the horizontal adjustment device 4 each include a drive mechanism. The drive mechanism is powered and / or controlled via pipelines. The pipelines are arranged completely or in sections in the pipeline guide.

[0055] The patient support table 1 includes a guide section 6. The guide section 6 is arranged on the floor section 7 and is screwed or connected thereto. The guide section 6 comprises a hollow profile, which is closed in the longitudinal direction L by means of a cover 8. The entrainment module 9 has two side sections 10, which are connected to the guide section, for example, in a form-fitting manner, so that the guide section 6 guides the entrainment module 9.

[0056] Figure 2 A detail of the patient support table 1 is shown, showing the entrainment module 9 and the guide section 6. The cover 8 is omitted here, so that the hollow profile and the components located therein are visible. The guide section 6 comprises two guide elements 11. These are arranged along the longitudinal direction L and form a track for the entrainment module 9. The side sections 10, for example, engage with the guide elements 11. The two guide elements 11 each have a guide section channel 12. In addition, a further guide section channel 12 is provided between the guide elements 11, which are arranged in parallel. The guide section channels 12 are each designed to accommodate a line guide 14 and / or are dimensioned accordingly.

[0057] Furthermore, the guide section 6 comprises two deflection modules 13, wherein one of the two deflection modules is Figure 2 . The second steering module is arranged at the other end of the guide section 6 along the longitudinal direction L. The steering modules 13 each include a rotatably supported steering roller. The pipeline guide 14 is guided around the steering module 13. The pipeline guide 14 has a curved section in the area of ​​the steering module 13, which can be understood as two arcs of an S-shape. In addition, the pipeline guide extends into the guide section channel 12 in the guide section 6, wherein the pipeline guide extends essentially without bending. The bend of the pipeline guide 14 in the curved section is opposite at the two steering modules 13. In the area of ​​the side section 10, the pipeline guide 14 is connected to the driving module so that the movement of the driving module drives the pipeline guide.

[0058] Figure 3 A more detailed cross section through the guide segment 6 is shown. The arrangement of the line guide 14 in the guide segment channel 12, as well as the rotatable mounting of the deflection module 13, can be seen more clearly in this case. Furthermore, the form-fitting engagement of the side segment 10 with the guide segment 6 or guide element 11 is visible.

[0059] The entraining module 9 has a sensor 15, which is designed to detect movement, travel and / or position in the longitudinal direction. The sensor 15 is connected to the control device of the drive of the entraining module 9 so that the entraining module can be positioned at a desired position and / or can be moved or advanced accordingly.

[0060] The guide section 6 includes a cover 16, which is designed and / or arranged to cover or close the guide section 6, in particular the guide section channel 12, at the top. The cover 16 is arranged, in particular, between the guide element 11 and the entrainment module 6. The cover 16 preferably extends over the entire longitudinal extension L and serves as protection against liquids, contamination, and force influences. The cover 16 can be directly integrated into the hollow body, but can also be designed to be installed separately.

[0061] Figure 4 A horizontal section is shown through the guide section 6. The top view from above shows the S-shaped course of the line guide 14 in the guide section.

[0062] Here, the S-shape corresponds to an elongated S or is similar to an integral symbol. The arc in the region of the deflection module 13 forms two arcs of the S-shape. Before, between, and after the deflection modules 13, the line guide runs essentially straight or without curves. Preferably, the line guides run essentially parallel to one another in the guide section channel and / or in the same orientation as the guide element 11.
