Description

Cable collecting and storing device
Technical Field
The utility model relates to a cable is received and is deposited device or cable memory (Kabelspeicher) say so.
Background
Such a cable storage device comprises at least one cable which can be connected to the device by means of a plug device, wherein the cable is guided by means of a cable guide device with a variable length between a first end point and a second end point. The cable storage device is designed, for example, in the form of a cable drum. The device may be, for example, a medical-technical device for examining a patient. Such medical devices, which are also referred to as medical facilities, include, for example, magnetic resonance imaging (MRT) devices.
In MRT systems, different coils for detecting the magnetic field are arranged around the patient to be examined in order to be imaged and are switched on accordingly for the purpose of recording. The coil encloses an examination space in which a patient to be examined is supported on a patient bed. The coils are attached to a table (Liegenbrett) of the patient bed, for example, in the region above the head or below or above the torso of the patient and require high-frequency (HF) cable connections to the MRT system. The interface between the coil and the high-frequency cable leading to the MRT apparatus is a plug position installed in the bed plate. The high-frequency cable connection is usually not guided through the magnetic field for imaging, but rather from the outside to the plug position and is contacted by means of the plug arrangement. In order to contact the plug arrangement in the plug position of the head coil (coil projecting into the head region of the patient), a high-frequency cable is guided from the outside into the examination space and is connected to the plug position at the head-side end of the lying plate. Since the couch plate is moved longitudinally when the patient is positioned in the examination space, the length of the high-frequency cable varies between the MRT apparatus and the plug position on the couch plate. The high-frequency cable must therefore be guided variably in length in relation to the position of the lying plate.
In one known solution, cable storage devices in the form of cable reels are provided for the high-frequency cables connected to the bed plate. The cable drum has an integrated torsion compensation device for the high-frequency cable. The paid-out high-frequency cable is pulled in by a spring, which winds up the high-frequency cable unwound and guided in a cable chain (kabelkete) again and is therefore also referred to as a retraction spring. The retraction spring generally has a characteristic curve which increases as the rf cable is pulled out or extended more. That is, the more the high frequency cable is spread out, the more the pulling force is generated on the lying plate connected to the high frequency cable.
The pulling force exerted by the recovery spring acts on the drive system of the lying plate. Thereby affecting the positioning accuracy of the board and possibly also the movement performance of the board.
SUMMERY OF THE UTILITY MODEL

According to the invention, the cable storage device has at least one cable which can be connected to the device, wherein the cable is guided by the cable guide device between the first end point and the second end point with a variable length. According to the invention, the cable guide comprises at least one vertically arranged cable return or cable loop (Kabelschleife) having a roller arranged in a stationary manner at a first end and having a roller which can be moved vertically at a second end.
According to the utility model discloses a cable is received and is deposited device comprises the vertical cable structure of arranging (one or more cable structure of bending back) of the quantity that can predetermine in principle, the length of cable structure of bending back shortens when pulling out or many cables.
The cable return structure is guided around a roller, wherein the upper roller or the upper rollers are attached in a stationary manner (first end point or first end points). The lower roller or rollers are designed as vertically movable rollers (second end point or points). It is advantageous for more than one lower roller to perform a common vertical movement of the rollers in the lower cable loop. The vertically movable rollers are preferably mechanically connected to one another for this purpose.
Through according to the utility model discloses a mechanical buffering of cable length has been ensured to the solution. The mechanical damping makes it possible to keep the mechanical characteristic values constant even when the cable length changes within certain limits. This reliably prevents twisting of the cable or cables and keeps the pull-out force constant, thereby increasing the service life accordingly.
According to the utility model discloses a solution is applicable to multiple cable. Such as high-frequency cables, power supply cables, tubes for conducting gaseous media or tubes for conducting liquid media, and can be connected to the device by means of a plug device. A prerequisite for this is that the bending radius is not less than the permissible bending radius for the respective cable.
The aforementioned cables and lines can be arranged in a cable chain or a cable tube, which is guided in the cable storage device according to the invention. Tensile loads are reliably prevented from acting on the cable or line when the cable is pulled out at the cable chain or hose, since tensile forces are taken up by the cable chain or hose.
Therefore according to the utility model discloses a solution both had been applicable to the cable in the aspect of the information technology and had also been applicable to the cable in the aspect of the electrotechnical technique. In both cases, a single-core or multi-core composite of individual conductors (cable cores) is respectively used, for example, for the optical or electrical transmission of information (data) or control commands or for the conduction of electrical current for the transmission of energy.
In a multi-core cable, each individual cable core is always enveloped by a respective insulation, i.e. core insulation, and an outer covering, i.e. cable jacket, surrounds all the cable cores.
The cable core serving as a conductor is enveloped by an insulating material, such as plastic, which insulates and shields the individual wires from each other. The cable sheath is used as an external coating structure to surround all the cable cores. The electrical conductor is made of copper, aluminum or a suitable metal alloy, for example. The optical waveguide is made of plastic fiber or quartz glass fiber (glass fiber cable).
In a cable storage device according to a preferred embodiment of the invention, the cable is a high frequency cable (HF-Kabel), for example an optical waveguide for optically transmitting data or a twisted pair cable for electrically transmitting data.
According to a further advantageous embodiment of the cable storage device according to the invention, the cable is an electrical (current-conducting) supply cable.
The concept according to the invention is also advantageously applicable to gaseous or liquid media.
According to the invention, the cable storage device can be advantageously connected to the device by means of a plug connection. The cable of the cable storage device can thus be connected to a component of the medical imaging apparatus, for example, by a plug connection.
If the medical device to be imaged is an MRT device, the relevant cables of the cable storage device are preferably connected to the components of the MRT device by means of a plug connection according to the invention.
Drawings
The exemplary embodiments of the invention, which are illustrated schematically, are explained in detail below with reference to the drawings, to which, however, the invention is not restricted.
Fig. 1 shows a side view of an MRT system, to which a cable storage device according to an embodiment of the invention is connected.
Detailed Description
In the single figure, the cable storage device is denoted by 1 and comprises a cable 2 or a cable guided in a cable chain or a cable tube, which is connected to an imaging medical device 3. In the illustrated embodiment, the medical imaging device is a magnetic resonance tomography device (MRT device). The cable 2 is designed as a high frequency cable (HF-Kabel). The high-frequency cable is hereinafter referred to collectively as "cable" because the solution according to the invention is applicable, for example, also to power supply cables and to hoses which are capable of transporting liquid or gaseous media.
In the exemplary embodiment shown, the connection of the cable storage device 1 to the MRT system 3 is effected via a plug device 4 on a component 5 of the MRT system 3. The cable 2 is held in a stationary manner in the cable storage device 1 by means of a cable holder 8. The component 5 is a lying plate. Said lying plate 5 being horizontally movable in the examination space in a first end position PE1And a second end position PE2To move in between. In addition to this, the bed plate 5 can also be moved vertically downward outside the MRT device 3 in order to make it easier to position the patient to be examined. The feasibility of such an adjustment is not shown for reasons of intuition.
The embodiment of the cable storage device 1 according to the invention shown in fig. 1 comprises exactly two cable return structures 6 and 7. Within the scope of the present invention, the cable storing device 1 may also include more or less cable return structures. The dependence of force and distance is based on the two cable return structures 6 and 7 shown.
The utility model can be easily scaled by increasing the number of cable return structures 6 and 7. Each cable return structure 6 or 7 always requires a stationary roller 61 or 71 and a vertically movable roller 62 or 72. The number of cable return arrangements 6 and 7 thus also determines the number of stationary rollers 61 and 71 and the number of vertically movable rollers 62 and 72 required. The fixed-position rollers 61 and 71 are respectively arranged in a fixed position at the first end point, and the vertically movable rollers 62 and 72 are respectively arranged in a vertically movable position at the second end point.
By the amount s of the respective vertical movements of the vertically movable rollers 62 and 7262Or s72The removal distance a of the lying plate 5 is calculated by multiplying twice the number of cable return arrangements 6 and 7. Due to the vertical movement s in the present case62And s72Same size(s)62＝s72S) and the cable storage device 1 comprises only two cable return structures 6 and 7, so that in the exemplary embodiment shown a removal distance of a 4s results.
By the weight force F of the vertically movable rollers 62 and 72R62And FR72The sum is divided by twice the number of vertically movable rollers 62 and 72 to calculate the pulling force F acting on the drawn-out cable 2Z. In the present case, two vertically displaceable rollers 62 and 72 are provided, which rollers 62 and 72 are mechanically connected to one another and thus perform a common vertical displacement.
In the illustrated embodiment with two vertically movable rollers 62 and 72, the following relationship applies for the pulling force according to the first vertically movable roller 62:
FZ1＝FR62/2。
the following relationship applies to the pulling force according to the second vertically movable roller 72:
FZ2＝FR72/2+FZ1。
due to FR62And FR72The size is the same (the mass of the two vertically movable rollers 62 and 72 is the same), thus obtaining:
FZ＝FZ1+FZ2＝FR/2+FR/2＝FR。
according to the utility model discloses a solution has avoided the torsion on the cable 2 when realizing the buffering of definite cable length. The cable 2 thus has a significantly longer service life.
A prerequisite for this is merely that the bending radius specified for the relevant cable 2 is maintained.
In addition, the utility model has the characteristic that the tension F on the cable 2ZIs constant irrespective of the pulled-out length a of the lying plate 5. This avoids the tensile forces F on the cable 2 that occur in the known solutionsZThe size is different. This can improve the positioning accuracy and the moving performance of the lying plate 5.
The solution according to the invention is simpler in design with respect to known solutions, such as special designs of cable reels and cable chains with reverse winding. When the cable chain is unwound and thus paid out on the cable winding side, the torsional movement on the cable due to the unwound cable chain, which is arranged in the housing, must be compensated at the same time on the opposite side of the rotational axis. Disadvantageously, the pull-out length a is subject to relatively strong limitations in such designs.
