Definitions

  • the invention relates to a device for transferring bedridden patients, with a mobile underframe which can be ascertained via a parking brake, with a lying console which is height-adjustable and laterally displaceable relative to the underframe, and with a locking device for the lying console.
  • Such a device for transferring is known for example from DE-PS 26 58 649.
  • Devices of this type are used to transfer bed-ridden patients to a mobile couch or to transfer a patient accommodated on such a couch to a bed.
  • Such devices also called patient trolleys, have a mobile underframe that is placed next to a bed when changing beds.
  • the lying console is adjusted so that it comes to about the same level as the patient's lying surface in bed.
  • the couch console is horizontally displaceable in the lateral direction relative to the underframe, and it is brought so close to the patient to be transferred during a transfer process that it can easily be transferred from the bed to the couch console by a rotary movement.
  • the lying console including the patient, is moved horizontally until it comes to rest in a centrally aligned position above the base.
  • a locking device ensures that the lying console can be locked in its extreme sliding positions.
  • the carrying device which carries the lying console in a height-displaceable manner, cannot be moved relative to the base frame.
  • a frame which is also not relatively movable relative to the base frame, carries the laterally displaceable lying console, which can be pushed out of the frame only in one direction.
  • a relatively heavy and complicated tape transport device is provided on the frame, which ensures that one applied to the outer side region of the bedding console The patient is pulled into a central position on the lying console using the belt device.
  • Such a device is extremely complicated, cumbersome to operate and has the disadvantage that relatively heavy parts are arranged at a high distance from the ground on which the device is located. As a result, when the lying console is extended to the side, there is a risk that the device will tip over sideways.
  • the couch console which is moved out laterally is supported on the mattress of the patient bed.
  • the couch console can sink into the mattress material, which can damage the mattress cover and the mattress itself, and it is also very difficult to move the couch console sideways, along with the patient lying on it, from the bed.
  • the object of the present invention is therefore an easy to handle, safe, i.e. in particular to create a tilt-proof device of the type mentioned.
  • the object is achieved in that a solid block, which supports the lying console in a height-displaceable manner, is provided, which is carried by at least one guide element running transversely in the underframe between two lateral end positions, and in that the locking device is arranged on the block and can be controlled from the lying console Has locking element which can be snapped into the recesses provided on the guide element and thereby blocks the relative movement of the block.
  • the provision of a massive block of mass in the base ensures that the device is relatively low Focus.
  • the mass of a person lying on the couch console in a laterally displaced state then no longer triggers a tilting moment.
  • the block can be moved back and forth in the transverse direction between two lateral end points, these end points lying on the floor within the support points of the base frame.
  • the lying console itself cannot be displaced laterally relative to the block, but the lateral displaceability is achieved by laterally displacing the assembly of block and lying console. This eliminates the need for relative to provide heavyweight frames at the height of the lying console, from which the actual lying console can then be pulled out in the lateral direction.
  • the block can be moved sideways to bring the bed bracket to the patient's bed. It is then not necessary for the lying console to be supported on the mattress of the patient bed. The patient is then rolled from the lying surface of the patient bed onto the lying console by a lateral rotary movement, without the helpers having to lift the patient. Even in the case of heavy patients, the low center of gravity and a correspondingly massive design of the block completely prevent the risk of tipping over.
  • these components are also arranged very low and ensure that the considerable masses moved during the lateral displacement movement can be held immovably sideways in certain desired positions. This also precludes, for example, a relative movement between the solid block and the base frame when driving the device with the patient lying on it in tight bends. The possibility of control from the lying console leads to an easy handling of the device or its locking for the operating personnel.
  • the block is carried by at least two guide rails, at least one of which has the cutouts.
  • This measure has the advantage that particularly structurally simple and robust means are provided to guide the block and to ensure a locking connection between the block and the associated bed console and the underframe.
  • the guide rails have a square cross-sectional profile and are arranged in such a way that two diagonally opposite longitudinal edges lie vertically one above the other, and the cutouts are cut out in the region of the upper longitudinal edge.
  • This measure has the advantage that the block can be guided on the two roof-shaped longitudinal surfaces and that the cutouts can be made, for example, by simple milling into the guide rails.
  • the cutouts are approximately rectangular in plan view and, seen in the longitudinal direction of the guide rail, they are provided with run-in or run-out slopes.
  • This measure has the advantage that the latching element engages in the recesses in a gentle movement or disengages from them again, so that the latching element can engage in the recesses without jerking. On the one hand, this helps to protect the material and also gently slows down the movement.
  • the guide rail is chamfered in the area of its upper longitudinal edge.
  • This measure has the advantage that the locking element is in contact with a relatively large area of the guide rail before it engages in the recesses, so that the existing friction between these parts creates a braking effect as long as the locking element is along the guide rail between two cutouts moved.
  • the latching element has a bolt which can be pulled out of the recesses against a spring force and is accommodated together with the spring in a housing, the bolt being movable via lever arrangements which can be actuated from the lying console.
  • This measure has the advantage that, after it has been moved out of a recess by the operator, controlled from the lying console, after the lateral movement of the lying console and release of the lever arrangement, the spring element is pressed onto the guide rail, thereby causing the frictional force a braking effect is generated. As soon as the next recess is reached, the locking element is pressed into this recess by the spring and blocks a further movement. By actuating the lever arrangement again, the latching element can then be lifted out of the recess again and the block including the lying console can be laterally displaced again until the latching element engages again in a new recess. It is therefore not possible that the block including the lying console after disengaging the locking element from the recess and releasing it over a larger one If necessary, the path is accelerated so that there is no fear of a jerky movement of the patient even during the stopping movements.
  • a lever is provided on opposite transverse edges in the region of the underside of the lying console, which lever is connected to the spring-loaded bolt by means of a cable.
  • This measure has the advantage that an operator who grips the lying console in the area of the levers on the top can trigger the locking device by the fingers reaching onto the underside of the lying console.
  • the block has a vertically standing, U-shaped base body, in the vertical guide rods of which are arranged one behind the other in the longitudinal direction of the lying bracket, sliding bushings are accommodated, which are firmly connected to the underside of the lying console.
  • This measure has the advantage that structurally simple guide and support elements are provided for the lying console, the center of gravity of which in turn is very deep, namely in the area of the mass block. This means that there is no danger of tipping over even when the lying console is extremely raised.
  • a piston / cylinder unit is accommodated in the center of the U-shaped base body, the reciprocating piston, which is firmly connected to the underside of the lying console, can be actuated via a pump lever protruding from the base frame.
  • This measure has the advantage that the components necessary for the movement of the lying console in the vertical direction are also arranged in a low position on the mass block, thus also ensuring a low center of gravity again.
  • the force of the lifting piston acts exactly on the center of the lying console, so that a symmetrical, uniform distribution of forces on the lying console is achieved during the lifting movement.
  • projections are provided in the transverse direction on both sides of the base body, and a housing of the locking device is received in a thread opening in a projection.
  • This measure has the advantage that the locking device is arranged at a very low point of the block in the immediate vicinity of the guide rails, so that these components are also centrally located on the block at the lowest possible point.
  • the block is provided on its underside with transverse grooves which are triangular in cross section and have cavities for receiving rollers, the rollers running on the two upper inclined surfaces of the guide rails.
  • This measure has the advantage that the block, partially encompassing the running rails, is guided securely by them, so that low-friction guidance of the transversely displaceable components in the base frame can be achieved by appropriate design of the running rollers.
  • a counterpart is provided which engages under the block and the guide rail and is provided on its upper side with transverse grooves which are triangular in cross section and which have cavities for receiving rollers, the rollers on the two lower inclined surfaces of the guide rail run with the counterpart attached to the block.
  • This measure has the advantage that a roller cage is formed around the guide rails, which is supported at four points on the guide rail.
  • a further lowering is achieved with excellent support and guidance of the block including the lying console on the base.
  • a device 10 shown in FIGS. 1 and 2 for transferring bed-ridden patients has a mobile underframe 12 which carries a block 14 which can be moved transversely and which in turn carries a lying console 16 which is firmly connected to it in height.
  • the underframe 12 has two continuous side walls 18, 20 which are connected via cross plates 22, 24 (see FIG. 2).
  • the housing of the base frame 12 thus formed is provided with a powder coating.
  • the base 12 is provided on its underside with four wheels 26, 26 '... which are pivotable about vertical journals 28, 28' ...
  • two guide elements 30, 32 extend between the opposite side walls 18, 20, which consist of two guide rails 34, 36, which have an approximately square cross-sectional profile.
  • the guide rail 34 (the same applies to the guide slide 36) is arranged in such a way that its upper longitudinal edge 38 comes to rest perpendicularly over its lower longitudinal edge 40.
  • the block 14 has a U-shaped base body 42 (see in particular Fig. 1), which in the transverse direction, i.e. seen in the longitudinal direction of the guide rail 34, is integrally connected on both sides with projections 44, 46.
  • the block 14 consists of an aluminum casting.
  • the block has a weight of approx. 50 kg.
  • the block 14 On its underside, the block 14 is provided with a transverse groove 48 (see in particular FIG. 1) which is triangular in cross section and has lateral cavities in which rollers 50, 50 'are received.
  • a further groove corresponding to the groove 48 is provided at the location on the underside of the block 14 at which it rests on the guide rail 34.
  • rollers are accommodated in the groove (which are omitted in FIG. 1 for illustrative reasons), which also run on the upper roof surfaces of the guide rail 34.
  • a counterpart 52 is arranged (see in particular FIGS. 1 and 3), which is provided on its upper side in the region of the guide rail 36 with a corresponding groove 54, in which rollers 56 in corresponding cavities , 56 'are included.
  • Another groove is provided in the area of the guide rail 34.
  • the counterpart 42 is connected to the underside of the block 14 by means of fasteners 58, not shown here.
  • the guide rails 34 and 36 are thus encompassed by the block 14 together with the counterpart 42 in the manner of a roller cage, which enables smooth sliding without play along the guide rails 34 and 36.
  • guide rods 64, 66 are received in self-lubricating bushings 68, 70, which are firmly connected to the underside of a plate 72.
  • the lying console 16 is placed on the plate 72 and releasably connected to it.
  • the guide rods 64 and 66 are designed as solid rod tubes in the exemplary embodiment shown, but they can also be designed as hollow tubes for reasons of weight saving.
  • a piston / cylinder unit 74 the piston 76 of which is connected to the underside of the plate 72, is received in the U-shaped base body in a vertically continuous opening in the center between the U-legs 60, 62.
  • the piston / cylinder unit 74 is connected to a hose 78 and a control unit (not shown here) with a Pump lever 80 connected, which extends from the base frame 12 of the transverse plate 23.
  • the underframe 12 can be locked in place via a locking mechanism, of which only the locking levers 84, 84 '... can be seen in FIGS. 1 and 2, i.e. the wheels 26, 26 '... are locked.
  • the four locking levers 84, 84 '... are connected to one another in such a way that the actuation of one of the four locking levers 84, 84' ... actuates the parking brake.
  • the locking lever 84 To release the parking brake, as shown in Fig. 1 by an arrow 89, for example, the locking lever 84 must be actuated.
  • the associated release of the parking brake of the base frame 12 can only take place if the block 14 is in a central position, i.e. in a position in which the lying console 16 is not laterally displaced beyond the base frame 12.
  • a lock 86 for example connected to the locking lever 84 ', is provided, which can only be pivoted counterclockwise by approximately 90 ° if a sword 88 on the block 14 is in alignment with a corresponding groove in the lock 86. This is the case if the block 14 is in the previously mentioned center position.
  • a threaded opening 94 is provided in the area above the upper longitudinal edge 38 of the guide rail 34, into which a housing 92 of a locking device 90 is screwed.
  • a bolt 96 is received in the hollow cylindrical housing 92 and has a first upper cylindrical section 98 which extends through an opening in the housing 92 on the cover side.
  • the first cylindrical section 98 merges into a second cylindrical section 100 of larger diameter, which merges into a tapering section 102 which extends away from the underside of the housing 92 and thus also from the underside of the section 46 of the block 14.
  • a prestressed compression spring 104 is arranged, which has the tendency to remove the bolt 96 to push out of the housing 92.
  • the upper end of the bolt 96 is connected to a holding device 106 which is fixedly connected to the outer ends of two cables 108 and 110.
  • the cable pull 108 (see also FIG. 1) is connected to a lever 112 which is arranged on the underside of the lying console 16 and which is pivotally connected to the plate 72 about an axis 116.
  • the cable pull 110 is connected to a diametrically opposite lever 114 which is attached to the plate 72 so as to be pivotable about an axis 118. If the lever 112 or the lever 114 is moved in the direction of the underside of the lying console 16, the bolt 96 is raised in the illustration in FIG. 3, the tapering section 102 being drawn into the housing 92.
  • the contour of the inlet and outlet slopes 120, 120 '... is adapted to the contour of the tapering section 102 of the bolt 96.
  • the spring 104 presses the underside of the tapering section 102 against the upper longitudinal edge 38 of the guide rail 34. This already produces a braking effect, so that the block 14 together with the lying console 16 and possibly the patient lying thereon cannot be accelerated too much in the transverse direction.
  • the upper longitudinal edge 38 is chamfered, so that there is a relatively large engagement surface between the guide rail 34 and the underside of the bolt 96.
  • the bolt 96 approaches in the case of a movement of the recess 119 'directed to the right in accordance with the illustration in FIG. 3, it slides smoothly into the recess 119 'after reaching the run-in slope 120' and then blocks a further movement.
  • a recess 119 designated by reference number 119 * in FIG. 2 corresponds to a central position of the block 14, in which, as previously mentioned, the lock 86 of the locking mechanism of the base frame 12 can engage the sword 88 on the block 14 in such a way that the base 12 can be moved.
  • only one locking device 90 is provided in cooperation with the guide rail 34.
  • the lateral movement of the block 14 is stopped by buffer elements 37 and 39, respectively, in that they come into contact with the inside of the side walls 18, 20.
  • the massive design of the block in the bottom arrangement on the base frame 12 ensures that even when in the maximum lateral displacement position shown in FIG. 2 on the lying console 16 on the outermost one protruding edge is a heavy person, the device does not tip.
