Definitions

  • the invention relates to a hospital bed with an endless belt which is guided around support bodies and can be driven in both circumferential directions and which is at least partially provided with a cushion on the outside.
  • Sick beds of this type which are intended in particular for patients who are unable to turn themselves and which have to be moved to a different position several times a day in the event of prolonged bed rest, serve to facilitate the rearrangement of the patients.
  • a bed of this type is known from FR-A-1 400068.
  • the endless belt provided with a cushion is guided around two axes mounted on the two long sides of the bed and an eccentrically mounted drum on the underside of the bed, by means of which the belt can be driven in both circumferential directions.
  • the patient lies on the upper strand of the padded band stretched between the two upper axes.
  • the drum By turning the drum, the upper strand is moved in the transverse direction of the bed, and at the same time the tension of the band is reduced due to the eccentric bearing of the drum, and the strand hangs down like a groove, whereby the patient is to be put on one side.
  • a hospital bed of a similar type is known from DE-A-2623933. With him, an endless belt is guided around two spars arranged on the two long sides of the bed, which are mounted so as to be movable towards one another. In the rest position, the patient lies on the upper strand of the band stretched between the two bars. To reposition the patient, the patient is first moved laterally by rotating the band around the spars, whereupon the spars are moved towards one another, so that the band hangs down, whereby the patient is to be brought into a lateral position.
  • a patient transport device which has two endless conveyor belts arranged one above the other.
  • the conveyor belts are guided around a plurality of conveyor rollers extending along the device.
  • the outer rollers of the upper conveyor belt receiving the patient can be lifted vertically by means of a hydraulic cylinder.
  • the inner rollers are connected to the outer rollers by lifting brackets and are raised somewhat when the outer rollers are lifted, so that the conveyor belt takes the form of a cradle and the patient is secured against falling from the conveyor belt during transport.
  • the known hospital beds of the type mentioned at the outset have the disadvantage that, depending on the state of tension of the endless belt, the patient lies either on a taut, level surface or on an unstable, channel-shaped, downwardly hanging surface, both of which are uncomfortable.
  • neither the head nor the foot part of the pad can be swiveled upwards, as is the case with conventional hospital beds.
  • the invention seeks to remedy this.
  • the invention solves the problem of creating a bed of the type mentioned, in which the patient lies as comfortably as in a normal bed, and that both an effortless and gentle repositioning of the patient as well Swiveling the head and / or foot section of the bed frame allows.
  • the endless belt is guided around a multiplicity of supporting bodies which are arranged in a plurality of transverse rows spaced apart from one another along the bed and are carried by a carrying device which has at least two longitudinal parts stretched along the bed, at least in the region of the head - And / or the foot part of the bed frame runs between two transverse rows of the supporting body, each having a swivel axis oriented transversely to the longitudinal direction of the bed, about which the adjacent sections of the longitudinal parts are pivotable relative to one another.
  • the head and / or foot part of the bed frame with the support bodies arranged above it can be pivoted upwards.
  • the patient is supported not only by the endless band, but also essentially by the support body, a stable and yet comfortable pad that adapts to the respective position of the patient can be achieved without the band having to be stretched so tightly for reasons of stability that it forms a hard, unyielding base or would sag unstably at lower tension.
  • the jacket of the support body is made of flexible material.
  • the support body which is arranged between the outermost and the middle support bodies, is preferably liftable or at least in one of the at least five support body transverse rows on both sides of the bed can be swiveled upwards.
  • the laterally outermost support body is coupled to the liftable support body in such a way that when it is raised and lowered it is inevitably shifted towards the center line of the bed and back outwards. It is essential that it is not, as in the known transport device according to DE-A-1 906 488, that the outermost support body is raised, but rather the adjacent support body arranged within the bed.
  • the liftable support body can attack directly on the patient after the latter has been brought into the appropriate position above the support body by rotating the band, and the patient gently and without that Nursing staff must help, is turned to the side. If one were to lift the outermost support body on the side, the patient could not be brought into a position above it, because otherwise there would be a risk of it falling out of the side of the bed. One could only move the patient as far as is possible without such a danger, and try to turn him through the inclined position of the band resulting from the lifting of the outermost support body.
  • the endless belt is driven in the two circumferential directions preferably according to claim 3 by means of two traction means arranged at the head and foot end of the bed, to which the two edges of the belt are fastened. Further preferred embodiments of the invention are the subject of claims 4 to 10.
  • the sick bed shown has a conventional bed frame with a head part 1, a middle part 2 and a foot part 3, which are articulated at 4 and 5. (The patient lies with the head and torso over the head part, with the buttocks and thighs over the middle part and with the lower legs and feet over the foot part.)
  • Two chains 6, 7 are tensioned along the bed, on which three trusses 8, 9, 10 are attached are.
  • Each of the crossbeams 8, 9, 10 carries six pairs of coaxial rollers arranged next to one another, of which in the drawing the roller pairs carried by the crossbeam 8 are designated 11-16. This means that six rows of six rolls lying next to each other are arranged at intervals along the bed.
  • An endless belt 17 (Fig.
  • the mattress envelops the belt 17 as an endless sleeve 27 and is held on the belt by static friction and at the edges by (not shown) surface zip fasteners (brand name Velcro fasteners), so that it is carried along by it during its orbital movement.
  • the ends of the longitudinal chains 6 and 7 run between the upper and lower runs of the endless chain 18 and 19 and are detachably attached to beams 28, 29 attached to the ends of the head and foot sections 1 and 3. (Arms could also protrude on the beams between the runs to which the chains should be attached.)
  • the pairs of rollers 11-16 are made of foam and are freely rotatable on axes running in the longitudinal direction of the bed, of which only the axes of the pairs 11-14, namely 31-34, are designated in the drawing (FIGS. 2 and 3).
  • the traverse 8 consists of a central part 35 and two outer parts, of which only the left part, designated 36, is visible in the drawing (FIGS. 2 and 3).
  • the middle part 35 is fastened to the chains 6 and 7 and designed as a rectangular hollow profile in which the outer parts are slidably mounted.
  • the axes 33 and 34 of the middle pairs of rollers 13 and 14 are on the middle part 35, the axis 31 of the outermost pair of rollers 11 is on the outer part 36 and the axis 32 of the second outermost pair of rollers 12 is mounted on the free end of a lever 37 which is pivotable on the middle Part 35 is articulated.
  • a coupling member 38 is articulated at one end approximately in the middle of the lever 37 and at the other end at the end of the outer part 36.
  • An angle lever 39 is pivotally mounted on the outer part 36 and carries a rotatable roller 40, 41 at each of its two ends. The roller 40 rests on the underside of the coupling member 38 in the rest position shown in FIG. 2.
  • the cable 42 is deflected in the longitudinal direction of the bed by a deflection roller 43 and is guided downward in FIG. 1 to a pulling device 44, wherein it is guided between the upper and lower run of the endless chain 19 and through the beam 29.
  • the right part of the bed, not shown in FIGS. 2 and 3, is a mirror image of the left part, the corresponding cable is designated 45 and its deflection roller 46.
  • the parts described above in connection with the crossbeam 8 and the pairs of rollers 11-16 are provided accordingly for the crossbeams 9 and 10 and the pairs of rollers carried by them.
  • the on the left outer parts (the attached levers) of the traverses 9 and 10 acting cables are actuated in the pulling device 44 together with the cable pull 42, the cable pulls acting on the right outer parts together with the cable pull 45.
  • the cable pulls of the left or the right can be selected Side down in the longitudinal direction and released again. If the cable 42 is pulled downward in FIG. 1 with the pulling device 44, a torque acts in a clockwise direction on the angle lever 39. At the same time, a force acts on the axis of the angle lever 39 and thus on the outer part 36 of the cross member 8 outer cross member moves against the center of the cross member.
  • the coupling member 38 pushes the lever 37 with the pair of rollers 12 mounted on it upward into the position shown in FIG. 3.
  • the angle lever 39 is used to lift the coupling member 38, which is approximately aligned with the lever 37 in the rest position. Since the outermost pair of rollers 11 is shifted inward when the second outermost pair of rollers 12 is pivoted upward, the circumference of the band 17 remains constant, ie the band and mattress are not stretched. If the cable 42 and the two cables pulled together with it on the left side are released again, the second outermost pairs of rollers swivel down again because of their own weight and the pressure exerted on them by the mattress, the coupling elements ensuring that the outer cross member parts Push outermost pairs of rollers back into their rest position.
  • the belt 17 is detachably connected to the endless chains 18 and 19 along its two edges.
  • 4 shows the connection of the one band edge to the one chain in a schematic cross section through the upper chain center: the outer plates 48 of the chain are designed as angled pieces, on the parts of which are angled on the outer chain circumference, plates 49 are riveted.
  • a pin 50 projecting outward in the circumferential plane is attached with a head, and on the side facing away from the bed an inwardly projecting axis 51, on which a guide roller 52 is mounted.
  • the edge of the band 17 is provided with eyelets 53 which are held on the pins 50.
  • the guide roller 52 runs between two guide rails 54, 55 lying parallel to the orbital plane, whereby the chain is guided against rotation and displacement perpendicular to the orbital plane. A twisting and a displacement of the chain would otherwise be inevitable because of the tension exerted by the belt 17. A guide bar 56 between the chain runs finally prevents them from approaching. Instead of chains 18, 19, timing belts could also be used.
  • the two endless chains 18 and 19 z. B. driven counterclockwise.
  • the upper run of the belt 17 and the mattress 27 then transports the patient in the direction of the outer pairs of rollers 11, 12.
  • the drive is then switched off and the cable 42 and the two cables associated with it on the left side of the bed in FIG. 1 by means of the pulling device 44 operated.
  • the pair of rollers 12 and the pairs of rollers located behind them in the axial direction and arranged on the cross members 9 and 10 pivot upwards, the patient being turned to the side.
  • the patient then lies in the side position in the middle of the bed, and the cables can be relieved, whereupon the pairs of rollers return to the rest position.
  • the patient can be brought to the other side position using the cable 45 and the two other cables.
  • the tape is z. B. detached from the endless chain 18 and the longitudinal chains 6 and 7 from the beam 28.
  • the mattress 27 can then be pulled off the belt after the surface zip has been released.
  • the band 17 could also form the inner surface of the mattress cover 27, i. that is, the belt and mattress could be made in one piece, but removing the mattress for cleaning is more cumbersome.
  • the support device consisting of the traverses 8 to 10 and the longitudinal chains 6 and 7 does not have to carry the entire weight of the rollers, the mattress and the patient, because the parts 1, 2, 3 of the bed frame form a base for the mattress.
  • the tensile stress of the longitudinal chains 6 and 7 must be dimensioned so large that the mattress 27 slides easily over the base 1, 2, 3 in the direction of rotation during the drive. Furthermore, the tensile stress must also ensure that the longitudinal chains 6, 7 hold the cross members 8, 9, 10 in their mutual position and in particular prevent the cross members pivoting against one another.
  • the parts 1, 2, 3 can be easily pivoted against each other (about the pivot axes 4, 5), that is, for. B. the head part 6 are pivoted upwards because the longitudinal chains 6 and 7 are articulated and the beams 28, 29 holding them and the drive device 18-26 are fastened to the head and foot parts 1 and 3, that is to say they are pivoted with them.
  • the longitudinal chains 6 and 7 may be provided, the individual parts of which are connected to one another in an articulated manner, the articulated connections having to lie in the region of the pivot axes 4, 5.
  • the pulling device 44 could also be arranged on the underside of the bed and the two cable pulls 42, 45 could be directed downward on the beam 29. Furthermore, the pulling device 44 could be in the space between the lowest or uppermost row of rollers in FIG. 1, the belt 17 and the endless one Chain 19 and 18 attached to the longitudinal chains 6 and 7 and connecting lines from it between the runs of the chain 19 and 18 to be guided to a control device on the outside of the bed.
  • the endless belt 17 can e.g. B. consist of stretch-resistant material of the brand name »Stamoid «.
