[0001] Radiology holding unit with a radiology unit for a radiology device

[0002] Description

[0003] The present invention relates to a radiology facility with a radiology holding device, in particular for a radiology device, and to a radiology system with such a radiology holding device and a radiology device such as, in particular, a computed tomography (CT) scanner, a magnetic resonance imaging (MRI) scanner, an X-ray device, a radiotherapy device or the like.

[0004] Computed tomography (CT) scanners and magnetic resonance imaging (MRI) scanners often have a tube-like structure through which the patient is moved or moved during the necessary scans. In the following text, magnetic resonance imaging (MRI) and computed tomography (CT) scanners are generally referred to as X-ray machines. If a bedridden patient is to be X-rayed, or undergo an MRI or CT scan, the patient, either lying in a bed or sitting in a wheelchair, is moved into the room equipped with the X-ray machine and positioned next to the examination table or operating table. The patient must then be transferred from the bed, wheelchair, or examination table to the operating table before the MRI or CT scan can begin. These transfers and correct positioning procedures require considerable strength and time. The same applies to radiation therapy.For this procedure, a patient is positioned in a targeted manner and irradiated in a targeted way.

[0005] A radiology holding device, known from DE 20 2016 106 093, supports such procedures. A handgrip is mounted on an adjustable support arm, allowing a patient to hold onto it. The support arm can be fixed at an angle. By pulling a rope, a bolt can be unlocked from a circle of holes, allowing the entire support arm to be rotated. A disadvantage is its large footprint. The rope for unlocking the bolt rotates with the support arm. In many positions, the rope is difficult to reach for personnel of shorter stature or with limited arm reach. Motorized adjustment and angular locking are theoretically possible, but require a very powerful electric motor that generates sufficiently high torque even when stationary to prevent unintentional swiveling of the support arm during operation. The effort required for this is considerable.

[0006] EP 3 996 596 Bl discloses an improved radiology holding device in which a hook element can be attached to a swiveling support arm in different positions and in which the swiveling movement of the support arm can be conveniently locked in different positions. The known radiology holding device functions satisfactorily. However, a more flexible and improved application is desirable.

[0007] It is therefore the object of the present invention to provide an improved radiology device with which its use in radiology can be improved with less effort and which provides support for patients and operators.

[0008] This problem is solved by a radiology device with the features of claim 1. Preferred embodiments of the invention are the subject of the dependent claims. Further advantages and features of the present invention will become apparent from the general description and the description of the embodiments.

[0009] A radiology device according to the invention comprises a radiology holding device and is intended in particular for at least one radiology device, and preferably for at least one X-ray device, an MRI device, a CT device, a radiotherapy device, or a similar or comparable device. The radiology holding device comprises a mounting device and at least one support arm pivotably mounted thereon. The support arm comprises at least one axle section and at least one support section. At least one holding device, attachable to the support arm, is provided, for example, to provide a holding option for a patient, e.g., when sitting up or repositioning. The axle section of the support arm is pivotably mounted on the mounting device to allow the support arm to pivot.

[0010] In particular, the support arm comprises at least a first arm section and at least a second arm section. The arm sections of the support arm are particularly preferably adjustable relative to each other. In particular, the arm sections of the support arm are displaceable relative to each other.

[0011] The radiology holding device according to the invention has many advantages. A significant advantage is its ease of handling. Even shorter people can operate it easily.

[0012] The support arm can preferably be adjusted in height (working height). This makes working with it easier, as the working height of the support arm can be raised or lowered as needed. This is very advantageous for normal operation. It also simplifies alignment during operation. For example, the working area is increased because a collision with installed equipment during swiveling can be prevented by a prior height adjustment. Thus, the support arm can be swiveled under a (fixed or nearly fixed) monitor or under a (fixed or nearly fixed) irradiation or auxiliary device and raised back to a normal working position on the other side of the device. Conversely, the support arm can also be raised to be swiveled above an auxiliary device or fixture, or the like.Afterwards, the support arm can be returned to a suitable or normal working position. This allows for more versatile and flexible use.

[0013] In preferred further developments and embodiments, the support element of the support arm is mounted on the axle section in a height-adjustable manner and / or pivotable about an axis (particularly a substantially horizontal one). This allows the height of the support element of the support arm and at least the height of the radially outer end of the support arm to be changed. This increases its usability and adaptability.

[0014] Preferably, the support arm, including the axle section and the support section, is mounted on the mounting device in a height-adjustable manner. The mounting device can then be permanently attached, and the support arm can be adjusted for height on it.

[0015] In preferred embodiments, the support arm is mounted on a rail of the mounting device in a height-adjustable manner. For example, continuous adjustment of the height position is then possible. However, it is also possible to allow only certain predefined height settings or to fix them in place.

[0016] In all embodiments, it is preferred that the weight of the support arm is (partially and preferably largely or completely) balanced by a compensating device. For example, the weight of the support arm can be regularly balanced down to a residual weight of 1 kg, 2 kg, 5 kg, or 10 kg to allow an operator to adjust the height comfortably. The operator will generally not be the patient themselves.

[0017] The balancing device can include at least one counterweight. The counterweight can be used to balance the base weight of the support arm. For example, the balancing device can include at least one cable and at least one pulley with which the support arm, or even just its load-bearing section, is kept (approximately) level. This significantly facilitates holding and adjusting the load-bearing section at the (working) height for the operator.

[0018] Preferably, the compensating device comprises at least one spring unit. The spring unit (or one of the spring units) can be provided in addition to or instead of a counterweight or a balancing weight. A spring unit can also be designed as a compensating spring and (then) be designated as such.

[0019] In advantageous embodiments, the support arm is pre-loaded to a basic height position by (at least) one spring unit. This can be the normal resting position, but it can also be a preferred or most frequently used working position. This basic height position can be at any desired height. The basic height position can be at the very top, at the very bottom, or in a middle range.

[0020] In certain and preferred configurations, (only) a discrete number of different height positions can be set.

[0021] This simplifies the selection by reducing the number of options and can also be advantageous in terms of stability, as not all heights need to be structurally secured.

[0022] Preferably, in the case of a discrete number of different height positions, at least one locking element is included with which the support arm can be fixed in at least one or two and, in particular, in the different height positions.

[0023] The swiveling support arm can be adjusted in length. This makes swiveling easier, as the length of the support arm can be shortened if necessary to prevent collisions with walls, equipment, or people.

[0024] The support part of the support arm is preferably mounted in a height-adjustable manner.

[0025] In preferred training courses, the radiology facility exhibits one or more or all of the features and characteristics of a previously described radiology facility.

[0026] In all embodiments, the radial length of the support arm is preferably variable. This is particularly advantageous. Preferably, the first and second arm sections are telescopic.

[0027] Preferably, the radially outer arm section is movable. In particular, it is possible for the radially outer arm section to extend into the radially inner arm section. The second arm section is preferably guided on (and especially within) the first arm section.

[0028] It is also possible and preferred that one arm section is pivotable relative to the other arm section. Alternatively, one arm section may be foldable and adjustable, for example, by 90° (or another angle). In particular, horizontal pivoting or folding is possible.

[0029] In all embodiments, it is preferred that a control unit is included. The control unit controls, in particular, the radiology support device. The control unit can also control a radiology unit or the entire radiology system. Preferably, at least one locking element controllable by the control unit is included, which, in at least one locking position, at least limits and / or, in particular, prevents relative movement of the two arm sections relative to each other. The control unit can also limit or prevent height adjustment of the support arm.

[0030] In advantageous embodiments, the locking element is received on the first arm section. In advantageous embodiments, the locking element is received on or in the first arm section at the proximal end of the first arm section.

[0031] Preferably, the locking position is a retracted position, and particularly preferably the fully retracted position of both arm parts.

[0032] Preferably, the locking element locks the two arm sections (only) in a retracted position. Then the locking element is in the locked position.

[0033] In all embodiments, it is preferred that one or at least one arm sensor is included. In particular, the arm sensor detects at least one defined relative position of the two arm sections to each other. This allows for control depending on the position of the arm sections relative to each other. The arm sensor can (in simple cases only) detect a specific position. The arm sensor can also continuously detect a change in position or an absolute position. In simple cases, the arm sensor detects the (fully) retracted position and then outputs a signal or closes a circuit, or the like.

[0034] Preferably, the angular and / or vertical position of the support arm can be limited and / or restricted by a limiting device (particularly in the form of a stop unit) for the swivel angle. This allows for a fundamental swivel angle limitation of the support arm to prevent, for example, a collision with a wall or a fixed installation. It also ensures that no continuous rotation occurs. This is generally advantageous because continuous rotation typically requires sliding contacts to maintain the data and / or power connection. If such transmission is wireless, a swivel angle limitation is therefore unnecessary. However, a swivel angle limitation can also be useful or necessary to prevent collisions with other objects.In simple designs, a stop unit is provided as a swivel angle limiter and / or, if necessary, a limiter for height adjustment.

[0035] However, it is also possible to dynamically limit a swivel angle.

[0036] In particular, at least one angle sensor is included for detecting at least one angular position (of the support arm). The angle sensor preferably detects the swivel angle, an angular position, or a measure of the angle of the support arm. The angle sensor can be designed as an optical, magnetic, capacitive, and / or mechanical sensor. It is essential that the angle sensor reliably detects at least one angular position of the support arm. In particular, the angle sensor detects whether the support arm is at the boundary of a working range.

[0037] Preferably, at least one working range and at least one locking range are adjustable. It is particularly preferred (and controllable by the control unit) that the support arm can be pivoted (only) within the working range when extended. The angle sensor detects, in particular, the end of the working range when the support arm is pivoted towards it. This can be achieved, for example, via a capacitive proximity sensor.

[0038] In all configurations, the working area and the restricted area may depend on the height position of the supporting component. A complex three-dimensional profile of the working area and restricted area may result from or already exist.

[0039] Preferably, a locking zone (directly or indirectly) adjoins the working area. In particular, the locking element blocks relative movement of the two arm sections in an angular position within the locking zone or in an angular position directly adjacent to the locking zone. This means that extension of the second arm section from the first arm section (or vice versa) is only possible if the support arm is located outside the locking zone within the working area. It is possible that a locking element abuts a (fixed or movable) stop of the stop unit when the support arm is to be pivoted into an angular position within the locking zone. Stops at the ends of the working area are also possible.

[0040] It is possible and preferred that the control device regulates the maximum extension length of the support arm depending on the swivel angle of the support arm. This allows for better and overall greater swiveling, while preventing collisions with devices at varying distances. It is advantageous if the control device regulates the swiveling and extension of the support arm depending on the height of the support element.

[0041] Preferably, at least one locking element is included, which can be moved into a release position and (at least) a locking position, and which, in the locking position, prevents the support arm from pivoting out of the working area into the locked area (e.g., mechanically). It is possible that the support arm can also pivot into the locked area when fully retracted. In the locking position, the locking element preferably does not completely block pivoting of the support arm, but (only) prevents it from pivoting out of the working area.

[0042] In principle, the swivel range can extend over an angle range of up to 360° or more.

[0043] In all configurations, it is also possible that the (maximum) possible swivel angle depends on the relative position of the

[0044] The relationship between the arm sections depends on each other. This can be controlled by the control unit (electrical or electronic) and / or by a mechanical (curve) control.

[0045] In preferred embodiments, the control device is designed and configured to control the locking element and to move the locking element into the locking position when the support arm is in an extended position.

[0046] Preferably, the blocking element is moved into the blocking position when a power supply is switched off.

[0047] In particular, the locking element is moved into the locking position when the power supply is switched off.

[0048] It is particularly advantageous for the blocking element and the locking element to be pre-loaded into the blocking position and the locking position, respectively. This ensures reliable blocking even in the event of an unexpected power failure.

[0049] In all configurations and further developments, at least one radiology device is preferably included. In particular, at least one auxiliary device, such as a radiation device, sensor device, camera device, or display device, is located at least temporarily within the restricted area. Alternatively, the restricted area is defined by the presence and location of an auxiliary device.

[0050] In all further developments and configurations, the control device is specifically designed and configured to allow the support arm to pivot from the working area into the (especially height-dependent) restricted area only when the support arm is in a relatively retracted position at least partially, so that an auxiliary device is not touched or hit when the support arm pivots.

[0051] The radiology support device preferably has at least one locking mechanism to lock the support arm in at least one angular position. The angular position in which the support arm can be locked is a locking position.

[0052] In particular, at least one (especially manual) actuating mechanism is provided to operate the locking device and, in particular, to release and / or lock it. At least one holding device attachable to the support arm is provided to, for example, offer a patient a means of support. This allows the patient, for example, to hold onto the holding device, pull themselves up, reposition themselves, or assist in repositioning. The axle section of the (or each) support arm is pivotably mounted on the attachment device and, in particular, supported therein. This allows the support arm to be easily pivoted to enable different working positions. The actuating mechanism can include at least one transmission element that passes through at least one hollow section of the axle section.

[0053] Such a radiology system with a radiology holding device is very advantageous. A significant benefit is its ease of use. Even shorter individuals can operate it easily. It is also advantageous that the transmission element is guided through the hollow axis, thus reducing the risk of contamination.

[0054] In its intended, assembled, or ready-to-use state, a rotation axis is oriented at least substantially vertically, or approximately vertically, or (nearly or exactly) vertically, or at an angle. The mounting device is preferably designed as a mounting bracket, which is attached, in particular, to the ceiling of a room, e.g., a radiology department.

[0055] The fastening device can be designed in other configurations, particularly as a wall mounting, which is supported against, for example, a substantially vertical wall of the room. The fastening device can also stand on the floor.

[0056] The support device is designed, in particular, as a handrail or includes one. The support device (or handrail) is, in particular, height-adjustable and can thus be adapted to shorter and taller individuals. Preferably, the support device or at least one handrail is adjustable in height by at least 100 mm, and in particular by 200 or 300 mm, or even 500 mm or more, and, for example, also by 1 m or more. With a height-adjustable support arm, the height adjustability may be reduced or may not be present.

[0057] The support element, or its underside, is preferably positioned at a height of 2250 mm or more. The holding device can preferably be positioned at a height of 2000 mm or more.

[0058] The mounting device can also be located directly on the radiology equipment and / or, in particular, integrated into and / or attached to it. In this case, and in other cases as well, the orientation of the support arm's axis of rotation can be adjusted by means of an adapter. The operating device can also be mounted on a wall or on the floor.

[0059] The support arm is preferably rotatable, in particular at least pivotable, and is arranged and / or received and preferably fastened on at least the mounting device of the radiology holding device. In particular, the transmission element moves at least section by section substantially axially along the axis of rotation or closely adjacent to the axis of rotation when the actuating mechanism is actuated. Preferably, the transmission element moves at least section by section through the axle part, which is in particular hollow.

[0060] By routing the transmission element through the hollow section of the axle, the radiology support system as a whole, and especially the support arm, is particularly compact and space-saving. The transmission element does not need to rotate around a pivot axis of the support arm when the arm is swiveled. Consequently, routing it through a magnetic shield is particularly easy. No slot, elongated hole, or linear opening is necessary to allow the transmission element to swivel through any shielding or partition. Sealing and shielding are significantly simplified. The transmission can also be electrically controlled. An operating element on the support arm can be activated by the operator, and the release for rotation of the support arm can be electrically controlled.

[0061] If the radiology support device is installed through a suspended ceiling with, for example, magnetic shielding (Faraday cage), the penetration area is limited to the cross-sectional area of ​​the axis section. This means the shielding only needs to be opened and / or penetrated over a minimal cross-section. The resulting hole in the shielding requires less complex sealing, or may not even need to be sealed at all.

[0062] The transmission element is preferably made of a non-magnetic and / or non-electrically conductive material. This prevents the transmission element from acting as an antenna. This applies particularly in the area where it passes through the axle section and especially through the shielding and in the immediately adjacent areas or the immediate vicinity.

[0063] The radiology holding device is particularly capable of withstanding a force of at least 1350 N, or at least 1500 N, or 1700 N, or 2000 N, preferably in the direction of gravity. In a heavy-duty version, the radiology holding device is preferably capable of withstanding a force of up to 5000 N.

[0064] The radiology holding device is designed to withstand a clamping torque of at least 5.5 kNm or at least 6.5 kNm, or, in a heavy-duty version, at least 10.0 kNm. The radiology holding device can preferably also be designed to withstand smaller or larger forces and / or clamping torques. This depends primarily on the expected load. If mainly or exclusively children are to be transferred, the load limit can be significantly lower. In special radiology systems for severely obese patients, the radiology holding device can also be designed for correspondingly much higher loads.

[0065] The actuating mechanism of the radiology holding device is particularly advantageous if it can be actuated by at least one actuating element. An actuating element can particularly preferably be designed as a knob and / or button and / or handle. It is also possible for an actuating element to be formed by a rope loop and / or a rope end. Other geometric shapes or bodies are also possible.

[0066] The actuating element can be positioned directly centrally and centrically below the support arm, particularly by passing the transmission element through the hollow axle section. This allows the actuating mechanism for pivoting the support arm to be operated centrally from many positions by a single user, via the actuating element and the transmission element. When the support arm is pivoted, the position of the actuating element changes almost not at all, if at all. This allows for a smaller distance between the actuating element and the radially outer end of the support arm. This makes operation and pivoting easier, especially for shorter individuals, when the working position is a large radial distance from the axis of rotation.

[0067] The actuating element can also be designed as an electrical sensor and / or switch. In this case, the locking device is electrically actuated via the actuating mechanism.

[0068] Preferably, the actuating mechanism can be actuated by at least two independent (in particular mechanical) actuating elements. In simple cases, at least one part or section of a transmission element can be formed by a rope or thread or the like.

[0069] In particular, more than two actuating elements are present, by which the actuating mechanism can be actuated separately. Specifically, the two or at least two actuating elements are arranged at different radial distances from the central pivot or rotation axis of the support arm. At least two actuating elements can be arranged or connected to the transmission element in series and / or parallel. The actuating elements can be aligned so that actuation is advantageously possible from different positions on the support arm. An actuating element can also be formed by the transmission element itself. For this purpose, an actuating element can be formed by an approximately horizontally extending section of the transmission element.

[0070] Particularly preferably, at least one actuating element, by which the locking device can be actuated, is arranged and / or attached radially outside the mounting device. Advantageously, an actuating element is arranged directly adjacent to at least one holding device. A holding device can preferably be arranged near or at the radial end, i.e., at a large radius of the support arm. Advantageously, actuation can also be performed from near a holding device. Possibly even by a patient themselves, if this does not significantly impair safety. Furthermore, simple actuation by at least one assisting person is possible. Then, for example, an operator can pull on the actuating element and thereby on the device.Pull the transmission element, which is designed as a rope, thereby releasing the locking device and simultaneously pivoting the support arm into a desired position.

[0071] Preferably, the locking device of the radiology holding device creates a force-locking and / or form-locking connection between the support arm and the fastening device.

[0072] The locking device is preferably designed as a positive locking mechanism. Here, the angular position is fixed by interlocking positive locking elements. It is possible to form the positive locking connection by interlocking elements, by a toothed joint, or by another positive locking contour.

[0073] Advantageously, the locking device comprises at least one fixing element for locking the locking device. Preferably, the transmission element can be moved from a locking position to a rotational position in which the angular position of the support arm relative to the fastening device can be changed. Particularly preferably, (fixed) detents are provided.

[0074] The transmission element is connected to the fixing element (directly and / or indirectly by friction and / or positive locking). The transmission element can also be designed as an electrical conductor and / or actuator, or at least include one. In this and other cases, at least one additional actuator or actuator may be included. For example, a servo motor may be present, by which the fixing element can be moved from the fixed position to the rotating position (and vice versa).

[0075] It is possible for the radiology holding device to be pivoted, rotated, and / or adjusted in height by at least one actuator, and in particular by a motor, preferably an electric motor. In this case, the radiology holding device can be pivoted, in particular by remote control, which has a radio or cable connection to the actuator. In preferred embodiments, the radiology holding device can only be pivoted by the actuator when it is locked in a secure position. Such a safety function can preferably be overridden by at least one safety switch. When this switch is actuated, the radiology holding device can be pivoted even if it is not in a locked position. Preferably, no motor-driven or electrically driven actuator is used to adjust the height and / or angle.

[0076] In all embodiments, the locking device preferably comprises at least one locking element which engages in at least one detent element of a plurality of detent elements. A locking element is particularly formed and / or arranged on the fastening device to enable multiple locking positions.

[0077] A locking element is designed in particular as a recess and preferably as a hole or bore. At least one fixing element is designed in particular as an engagement element, which enables or establishes a positive-locking connection with the fastening device. At least one engagement element is advantageously designed as a bolt, which engages positively in a locking position in a corresponding hole in the fastening device.

[0078] The fixing element, as part of the locking device, is preferably arranged on the support arm. A plurality of recesses are preferably formed on and / or arranged on the fastening device.

[0079] However, the assignment of the bolts and the recesses to the support arm and the fastening device can also be exactly the opposite if this appears structurally necessary or desirable.

[0080] Designing the locking device with at least one bolt as a fixing element or engagement element, which engages in a hole of a bolt circle, offers the advantage that the locking device is particularly easy and cost-effective to manufacture. The design is very robust.

[0081] The positive-locking connection can effectively absorb lateral forces and torques and reliably lock the support arm in a fixed position. The mechanism can be positioned centrally and in a space-saving manner around the axis of rotation of the support arm.

[0082] Particularly preferred are a plurality of recesses and especially holes and / or bores distributed around a circumference on a disk or, for example, a ring, particularly as a (regular) circle of holes, which is arranged on the fastening device. By pivoting the support arm, the bolt of the support arm can be locked in the various angular positions by engaging one of the holes distributed around the circumference of the circle of holes. The support arm can then be fixed in the desired position.

[0083] Preferably, the radiology holding device comprises at least one preloading device by which the engagement element can be preloaded into the locking position. Due to the preloading device, the locking device is particularly preferably regularly or (almost) always in the locking position when it is not in the rotational position due to the actuating mechanism. Preloading is particularly possible by at least one preload spring, which presses the bolt, as a fixing element, into the hole of the corresponding locking position at appropriate angular positions.

[0084] During rotation, the locking element preferably engages automatically via the preloading device when the locking element engages with a recess during the rotation. This advantageously preloads the support arm regularly or always into a fixed angular position.

[0085] Due to the preloading of the fixing element into the locking position, the support arm of the radiology holding device is securely locked in its angular position, i.e., the locked position. A person can safely pull themselves up and / or support themselves on the radiology holding device, making it suitable for transferring a patient without twisting. Even in the event of vibrations and / or sudden movements of any component of the radiology holding device, the support arm remains reliably locked in its angular position and cannot be moved by impulses.

[0086] The transmission element preferably comprises at least one flexible tension element. The flexible tension element is preferably designed as a rope or pull cord, tape, thread, rubber band, and / or chain, or comprises at least one such element. The transmission element is preferably designed as a flexible tension element. The transmission element can also be multi-part. At least one component can be designed as a rigid rod or comprise one.

[0087] In a particularly advantageous embodiment, the transmission element is guided from inside the axle section to a region radially outside the axle section. The transmission element is preferably (and particularly space-savingly) guided through the axle section itself. This eliminates the need for the transmission element to be guided separately through an opening in the suspended ceiling that requires a separate seal, as is the case in the prior art. The necessary opening is thus limited to the axle section and its cross-section. The transmission element does not need to rotate around the axle section when the support arm pivots. The transmission element pivots essentially centrally with the axle section.

[0088] Particularly preferably, the transmission element is received and / or guided over at least a quarter or at least half the length of the support part or the first arm part.

[0089] Preferably, the transmission element is guided by at least one guide unit within the axle section and / or at least once from the inside to the outside of the axle section. The transmission element is particularly preferably guided within the axle section by a guide unit designed as a guide rail.

[0090] Designing the transmission element as a mechanical pull element, such as a rope, chain, or strap, offers the advantage that a button and / or knob can be attached to its end as an actuating element, thereby enabling the actuating mechanism to be operated. Preferably, the actuating mechanism comprises at least one force direction unit. Advantageously, the force direction unit includes at least one retaining element, on which the flexible pull element is specifically mounted. The actuating mechanism is simple and direct to operate. When actuated, a flexible pull element can easily compensate for small changes in the position of an operator's hand, so that the actuating element moves with the hand of the patient and / or operator. The direction and / or orientation and / or spatial course of the pull element can advantageously be arranged variably for the user, so that the end of the rope can also be used directly as an actuating element.

[0091] A design of the transmission element as a mechanical tension element also offers the advantage that at least two actuating elements can be easily connected to the transmission element in series and / or parallel. This makes it advantageously possible for the actuating mechanism to be operated by at least two actuating elements. A flexible tension element of the transmission element is also preferably routed along the support arm and, in particular, along the support section. The transmission element itself can also be used as an actuating element. Different actuating elements can be radially spaced from each other, so that actuation from different positions along the support arm and, in particular, along the support section of the support arm is possible.

[0092] The risk that the locking device, especially when transferring patients, cannot be operated or can only be operated with a very long and / or undefined actuation path is minimized or even completely eliminated.

[0093] The flexible tension element or transmission element can be positioned at a greater horizontal distance from the locking device. Even with a long horizontal guide for the flexible tension element, the proportion of the applied tension force or the actuation path that does not contribute to actuating the locking mechanism is minimized.

[0094] Even if the flexible pull element sags and if several pull elements and / or actuating elements are connected in series or linked together, a defined and always the same or almost the same actuating path can be set.

[0095] Overall, the usability of the radiology holding device, and especially the support arm, is improved. The reliability of the actuation mechanism is significantly enhanced. The defined positioning of the transmission element and the flexible pull element protects them from excessive contamination. The actuation element is always gripped at the same point, which significantly improves hygiene of the radiology holding device. Furthermore, the actuation mechanism is much easier to handle, simplifying its use.

[0096] Advantageously, the radiology support device includes at least one limiting device for restricting a swivel angle. The swivel angle limiting device can particularly preferably be designed as a stop, which is, for example, arranged and / or attached to the mounting device. The limiting device for restricting the swivel angle, or the swivel angle limiting device itself, serves to restrict the swivel angle of the support arm, preferably to a total rotation angle, e.g., to a swivel angle of 270°, 180°, or 90°. The specific angle depends on the individual case and the specific conditions. The swivel angle can therefore also be limited to a smaller total angle, which results from the arrangement in the installation space and / or the division and number of possible fixed positions. A design of the radiology support device without a limiting device is also possible.

[0097] The swivel angle limiting device preferably includes a damping element that enables a soft and damped stop. The damping element is preferably designed as a rubber buffer and / or a gas spring and / or an elastic band. This allows a radiology holding device to be arranged or integrated into a radiology room in such a way that its use can be adapted to the requirements and needs of a radiology system, a patient, or the operators, as well as the geometric dimensions of the room. Preferably, at least one stop can be provided on the locking device for this purpose. The limiting device can also be mounted on the wall of the room. In this case, the limiting device is not integrated into the locking device. This defines a working range for the radiology holding device.

[0098] The holding device comprises, in particular, at least one suspension element for hooking into the mounting rail. This element is designed, in particular, as a hook element, specifically as a carabiner or an open hook, or comprises, in particular, at least one such element. Preferably, in the case of an open hook element, the hook legs are dimensioned such that very large holding angles of 45° and more are possible.

[0099] Preferably, the holding device allows a holding angle of at least 45°. Advantageously, the holding angle is measured relative to the vertical. Preferably, the holding angle is open in the direction of an gravitational acceleration vector. Preferably, holding angles of up to 60° and more are possible. This particularly advantageously achieves a secure hold in almost all possible positions. Removal of a holding device with an open hook from the mounting rail is preferably only possible at angles relative to the vertical that exceed, in particular, 30°, preferably 45°, and most preferably 60°. By sufficiently pivoting the holding device, or...By moving the open hook away from the vertical and pushing the open hook diagonally upwards, the open hook can be removed and the holding device can be hooked onto the mounting rail or another mounting rail via the open hook at a different position.

[0100] For advantageous storage of the holding device, at least one additional storage hook can be arranged, e.g., at the outer end of the support arm or at various longitudinal points for storing the holding device (when not in use). By hooking the holding device onto the storage hook, it does not obstruct pivoting movements of the support arm. This particularly advantageously enables simple, secure, and easily adjustable securing of the holding device.

[0101] A mounting point or attachment point can provide a locking position for the holding device. The function of the mounting rail is not limited to the mounting device. It can also be used, in particular, to hold infusions or infusion bags and / or infusion holders. Use for other functions is also conceivable. Separate infusion holders are also possible.

[0102] The attachment points are preferably formed by shaped elements into which a ring element of the holding device advantageously engages under tensile load. The attachment points can be formed by local "valleys" on the mounting rail, which are bounded by local "peaks" in between. This allows the position of the holding device to be changed along the support arm without having to release the positive locking connection between the mounting rail and the holding device. This allows the position of the holding device to be easily and quickly adjusted and changed between multiple positions. To do this, the holding device is simply slid to the next attachment point or lifted over the next "peak." The holding device does not need to be laboriously disassembled for this purpose, so it cannot fall off when the attachment position is changed. The risk of injury to a user is minimized.

[0103] The restraint system advantageously includes a strap unit. This strap unit is particularly advantageously positioned between the suspension element and the handle element. The strap unit primarily serves to facilitate a patient's lifting and repositioning. For this purpose, the length of the strap unit can be adjusted, optionally via a motor, to the needs and circumstances of the user.

[0104] In all configurations, it is possible for patients to assist themselves during repositioning or transfer. With the belt unit, it is particularly advantageous for patients to lift themselves using the positioning unit or the grab handle and thus assist in the transfer. This allows patients to be repositioned from positioning units designed as a bed, chair, or sling. Other types and designs of positioning units are also possible.

[0105] The necessary assistance from nursing or radiology staff during patient transfers is advantageously minimized. Ideally, a nurse should not need to assist with transfers at all. This significantly reduces the risk of transmitting bacteria, viruses, and germs. The potential for sexual harassment during or after transfers is also considerably reduced. Work absences due to psychological stress or transmitted germs are significantly minimized. This, in turn, improves the usability and cost-effectiveness of radiology equipment.

[0106] Advantageously, the radiology holding device is at least partially made of materials that are difficult and / or impossible to magnetize, or only weakly magnetize. High-intensity magnetic fields can occur during the operation of radiology equipment. Metallic materials with a corresponding molecular structure could become magnetized, which could lead to an interaction with the radiology equipment. Therefore, preferably all components and parts of the radiology holding device are made exclusively of materials that are only weakly magnetizable, and in particular, non-magnetizable, such as plastic and / or aluminum and / or stainless steel. However, it is advantageous if at least large parts of the radiology holding device are at least partially made of materials that are not magnetizable or only weakly magnetizable.This allows magnetic interactions (and thus artifacts during image acquisition) between the radiology holding device and the radiology unit to be eliminated and / or at least minimized. This primarily serves the safe and reliable operation of the radiology unit and the high quality of the images produced. A radiology system according to the invention preferably comprises at least one radiology unit and at least one radiology holding device.

[0107] In at least one advantageous embodiment, at least one transmission element is guided at least partially through a hollow section of the supporting part. Advantageously, a force direction unit can also be arranged at least partially within the supporting part. In this way, the tension element can be hygienically protected from contamination.

[0108] Advantageously, the radiology system includes at least one patient holding area for examination or treatment with the radiology device, which is at least partially located within the working area of ​​the radiology holding unit. Preferably, the patient holding area is centrally located within the working area of ​​the radiology holding unit, so that the working area of ​​the radiology holding unit can be used effectively.

[0109] Further advantages and features of the present invention will become apparent from the exemplary embodiments, which are explained below with reference to the accompanying figures. The figures show:

[0114] Figure 6 shows a schematic perspective view of a holding device, a radiology holding device.

[0115] Figures la bi s le show variants of a radiology facility 1 or a radiology system 100.

[0116] Figure 1a shows a radiology unit 1 in a side view, with the radiology support la attached to a wall of the room. Figure 1b shows the radiology unit 1 from Figure 1a in a top view. Figure 1c shows a variant in which the radiology support la is mounted on the ceiling. Figure 1ld shows a radiology unit 1 mounted on the floor. Figure 1le shows a variant with some details s that can be used in all embodiments. With reference to Figures 1a to 1le, the basic properties of the radiology unit 1 are described below. Identical or similar components or parts have the same reference numerals and are not described in detail for all variants.

[0117] Figure 1a shows the radiology holding device 1a, the radiology equipment 50, such as an X-ray machine 51, an MRI machine 52, a CT machine 53 or a radiotherapy machine 54 in a side view.

[0118] The radiology device 1 comprises a radiology holding device la with a mounting device 2, on which the support arm 3 is pivotably received and mounted. The support arm 3 comprises an axle section 4, which is pivotably attached to the mounting device 2, and a support section 5. The support arm 3, or the support section 5, has two telescopic arm sections 3a, 3b.

[0119] The radially inner (first) arm section 3a is connected to the axle section 4. The radially outer (second) arm section 3b is adjustable relative to the first arm section. Figure 1a shows the support section 5 in the extended position 3f. This allows the working area to be increased. Figure 1a shows a variant in which a mounting rail 23 with several attachment points 24 is provided at the bottom of the radially outer arm section 3b.

[0120] With a telescopic support element 5, this is not always necessary, and a mounting rail 23 can also be omitted, with only a single attachment point 24 being provided at the distal end, as shown in Figure 11. This simplifies the design and allows the radially outer support element 3b to be fully enclosed within the first support element 3a and slidably arranged therein.

[0121] In contrast to the illustration in Figure 1a, the second support element 3b can also be folded, for example, by a fixed angle of 45°, 60°, 75°, or 90° in the horizontal plane. This also changes the configuration and increases the working area that can be covered.

[0122] The support arm 3 is mounted on the mounting device 2 in a height-adjustable manner, as shown in Figure 1a. The entire support arm 3 is mounted on the rail 2a in a height-adjustable manner. The mounting device 2 is attached to the wall in this figure. However, it is also possible for the mounting device 2 to stand on the floor (Figure 11) or to be suspended from the ceiling (Figure 12).

[0123] In all embodiments, the weight of the support arm 3 is essentially balanced by a compensating device 36. This compensating device 36 comprises a counterweight 38, which lowers when the support arm 3 is moved upwards and is raised when it is moved downwards. The counterweight 38 is connected to the support arm 3 via a cable 38a and two pulleys 38b. The mass of the counterweight 38 is dimensioned such that it compensates for the majority of the weight of the support arm 3. This allows for easy height adjustment within the height range 34. The necessary force can easily be applied several times a day by an assistant or operator. Motorized adjustment without counterweight is also conceivable.

[0124] The adjustable height of the support arm facilitates operation. If necessary, the height of the swiveling support section 5 can be reduced when the support arm 3 needs to be swiveled through an area where an auxiliary device is mounted. Lowering (raising) the arm before swiveling and then raising (lowering) it afterward allows for improved usability.

[0125] On rail 2a, locking holes 2b are schematically shown, into which locking elements 2c in the form of, for example, locking pins can be inserted to fix the height of the support arm 3.

[0126] As schematically indicated within a dashed circle in a central area of ​​Figure 1a, the locking element can be pulled outwards from the locking hole against the force of the tension spring using a release button 39, thus lifting the lock. The support arm 3 can then be adjusted upwards or downwards with minimal effort. The locking element 2c automatically engages again at the next locking hole 2b. Depending on the design, height adjustment in two, three, or four positions may suffice. Adjusting the length of the support arm also facilitates operation and improves the swivel range, thereby expanding its application possibilities.

[0127] Figure 1b shows a top view, with the support arm 3 in the extended position 3f shown in two different angular positions. This results in a swivel range 44.

[0128] Figure 1c shows a variant in which the mounting device 2 is mounted on the ceiling of the room. A compensating device 36 with a spring unit 37 supports the support arm 3 and facilitates height adjustment within the height range 34.

[0129] Figure ld shows a variant in which the fastening device

[0130] 2 is mounted on the floor of the room. A compensating device 36 with a spring unit 37 supports the support arm 3 from below and also facilitates height adjustment within the height range 34. The support element 5 is shown here at a first height 34a and a second height 34b.

[0131] It is also possible to combine a counterweight 36 with one or more spring units 37, whereby one spring unit 37 can provide support from below and one can pull from above. The spring units can be designed as mechanical springs, such as coil springs. The use of gas springs or other spring types is also possible.

[0132] The mounting device 2 is shown in Figure 1 as a mounting bracket and is permanently mounted to the ceiling of a radiology room (not shown). The aperture device 18 is arranged centrally on the axle section 4 and covers the opening formed by the passage of the support arm.

[0133] 3 through the suspended ceiling, which here, for example, has magnetic shielding. If the radiology support device la is not guided through a suspended ceiling, the aperture device 18 is preferably designed such that it completely encloses the mounting device 2.

[0134] The radiology holding device la is located near a radiology device 50, such as an X-ray machine 51, an MRI machine 52, a CT machine 53, or a radiotherapy machine 54. The support arm 3 can be swivelled over the patient worktable 26 so that the holding device 9 is easily accessible to a patient.

[0135] The support section 5 of the support arm 3 comprises two telescopic arm sections 3a, 3b. As can be seen in Figure 1, a receiving rail 23 with several attachment points 24 is formed or attached to the second (distal) arm section 3b. A holding device 9 is suspended in one of the attachment points 24 of the receiving rail 23, against which a patient can support themselves for transfer and positioning. One attachment point 24 of the receiving rail 23 is designed as a "valley" between two "peaks" in the contour of the receiving rail 23. When the holding device 9 is subjected to tensile stress, as in intended use, the position of the holding device 9 in the attachment point 24 is positively locked by the geometry of the "valley".

[0136] The holding device 9 comprises a motor-driven or preferably mechanically spring-driven belt unit 32, by which the length of the holding device 9 is variably adjustable. A storage hook 29a for the holding device 9 is arranged at the radially outer end of the second arm section 3b. The holding device 9 can be placed over the storage hook 29a so that it does not interfere when the support arm 3 is pivoted. An infusion bag could also be attached to the support arm. A mounting rail 23 is formed on the second arm section 3b immediately radially adjacent to the handle knob, which serves as the actuating element 12. Under tensile load, as in intended use, the position of the ring loop of the holding device 9 is fixed in the attachment point 24. For adjustment, the holding device 9 can simply be pushed over a "mount" into another attachment point 24 without having to unhook a hook leg.This ensures a safe and durable construction.

[0137] For further adjustment, the second arm section 3b can be inserted into the first arm section 3a after a release button 48 has been pressed. Insertion from the extended position 3f to a further retracted position is possible at any angular position 43 of the support arm (after pressing the release button 48). A collision with an auxiliary device of the radiology unit 1 is not to be expected during insertion. The situation is different when the second arm section 3b is to be extended. The control unit 40 only allows the second arm section to be extended if there is no risk of collision with a radiology unit. Otherwise, relative movement of the two arm sections 3a and 3b is blocked. After actuation and the movement, the release button 48 automatically locks back into place.

[0138] By actuating the actuating mechanism 8, the support arm 3, which is held in the locking position 7 by the locking device 6, can be moved into a rotational position against the force of the preloading device 17. In the rotational position, the support arm 3 can pivot about the axis of rotation 4a of the axle part 4. This is only possible if the support arm 3 is in a working area 44 and not in a locking area 46, see Figure 3.

[0139] The transmission element 11 is designed here as a flexible tension element and connected to the locking device 6. The transmission element 11 is designed here as a tension cable, which is led axially downwards through the hollow section of the axle part 10 out of the axle part 4 and guided and arranged radially along the support part 5. The actuating mechanism 8 can be actuated by one of the actuating elements 12. A protective sleeve can be arranged on the transmission element 11 to protect against contamination. This sleeve is formed by the cable loop, i.e., the transmission element 11, and a knob or similar component.

[0140] The button, as actuating element 12, is directly adjacent to the

[0141] Mounting rail 23 is arranged. This enables comfortable and easy operation.

[0142] Figure 2 shows a schematic cross-section on the left and a schematic longitudinal section on the right through the support member 5 with the two arm sections 3a and 3b. On the left, it can be seen that the second arm section 3b is guided longitudinally (on bearings) inside the first arm section 3a. A locking opening 41b is visible in the second arm section 3b, into which the locking element 41 (right-hand figure) can engage to lock the two arm sections 3a and 3b together in the retracted position 3e. Extension is only possible when the locking element 41 is retracted from the locking opening.

[0143] An arm sensor 42 is attached to or integrated into the first arm section 3a, which detects when the second arm section 3b is in the (fully) retracted position 3e.

[0144] The locking element 41 locks the two arm parts together and thus prevents the second arm part 3b from extending when the support arm is in a locking area 46 (see Fig. 3) or when, for example, the power fails.

[0145] A retractable locking element 47 is schematically shown on top of the support section 5 of the support arm 3. In the extended locking position 47b, it rests directly against the stop unit 45 at the angle shown here. When pivoted in one direction, the extended stop unit 45 strikes the stop unit 45, thus preventing pivoting into the locking area 46. With the locking element 47 retracted, the support section 5 can be pivoted below the stop unit 45 (shown with a solid line). This is advantageous if the support arm 3, in a retracted position, can no longer collide with other equipment because the arm is too short.

[0146] The dashed line shows a further embodiment of the stop unit 45 with an angled shape. When the locking element 47 is extended, it prevents further pivoting, as before. When the locking element 47 is retracted, further pivoting by a certain amount is possible until the housing of the locking element 47 abuts the downwardly projecting dashed part of the stop unit 45.

[0147] In the right-hand representation of Figure 2, it can be seen schematically that the blocking element 47 rests against the stop unit 45.

[0148] It should be noted here that the blocking element 47 and the stop unit 45 are preferably arranged in the area of ​​the locking device 6 (see figure 1).

[0149] Figure 3 shows a highly schematic top view, with the axle section 4 clearly visible in the center. Several angular positions 43 of the support arm 3 are shown schematically, with the support arm 3 shown in one angular position in its retracted position 3e. Angle sensors 43a are provided on the support arm 3, which are suitable for determining at least certain angles. In simple cases, an angle determination is carried out via a proximity sensor, thus detecting when the working area is left.

[0150] Figure 3 also shows the bolt circle 15, in which the detent elements are formed as holes 14. A locking element 13 of the locking device 6 engages in these holes when the manually operated actuating element 12 is not actuated. By (manually) pulling on the actuating element 12, the transmission element 11 is pulled, thereby pulling the locking element 13 out of the detent element 14. This allows the support arm 3 to pivot, provided the blocking element 47 does not obstruct or prevent the pivoting.

[0151] It is also possible to omit a separate locking element 47 and for the control unit 40 (Figure 1) to control an electrically controlled locking device 6. The actuating element 12 then does not act directly on the locking element 13. The locking element 13 is then released electrically when the conditions are right.

[0152] In any case, pivoting of the support arm 3 is permitted if it is ensured that the support arm 3 does not collide with an auxiliary device 60. This can mean that the support arm 3 with the two arm sections 3a, 3b can be pivoted 360° or more in the retracted position 3e. In a partially or fully extended position 3f with full radial length 3c, however, the locking area 46 is locked.

[0153] As shown in Figure 4, the second arm section 3b can be extended from the first arm section 3a if the control device 40 has not locked the two arm sections 3a and 3b together via the locking element 41. In principle, the second arm section 3b can be extended if the support arm 3 or the support element 5 is located within the working area 44.

[0154] Figure 4 shows the two arm sections 3a and 3b, and Figure 5 shows arm section 3b in a schematic side view. The attachment points 24 are located in an upper area. The second arm section 3b can be extended from the first arm section 3a and rests on the base of the first arm section 3a.

[0155] Figure 6+ shows a holding device 9 to which a patient support unit 31 is attached, which can be moved up and down by the belt unit 32.

[0156] The housing of the belt unit 32 can be equipped with an actuating button 31a, which serves to actuate a winding unit (not visible here, as it is located inside), driven, for example, by a coil spring. When the button 31a is actuated, the belt can be automatically retracted and wound up (without force being applied), or the belt can be pulled out against the force of the coil spring. Preferably, a belt length of at least 200 or 300 mm is available. In advantageous embodiments, the extendable belt length can also be 500 mm or 750 mm or more. This has the advantage in high rooms that the retaining handle of the holding device 9 can be raised when not in use so that it does not obstruct the view and prevents head impact. Alternatively, it is also possible to hang the retaining handle on one of the hooks when not in use.

[0157] The belt 32e can be wound up or pulled out against the tension of a concealed coil spring located inside the belt. The retaining handle is rotatably mounted on the rod 32b along with the belt unit 32. The belt unit 32 is pivotally mounted via the sliding element 32d. The sliding element 32c serves as a bearing unit and is located between the upper bracket of the holder 32a and the enlarged head 32d of the rod 32b to allow smooth pivoting of the belt unit towards a patient. While the belt 32e can theoretically be twisted, this can lead to problems during operation if the belt winds up crookedly or improperly.

[0158] The invention provides an advantageous radiology device 1 which is versatile and flexible in its application.
