Definitions

  • the invention relates to a device for lifting or positioning a sick or disabled person (patient) with a base part, a plurality of support elements for the patient's body and a positioning device connecting the base part with the support elements.
  • the base part is usually wheeled on the floor.
  • the support elements can be slid under the patient's body.
  • the base part and the support elements are connected to one another via mechanical and / or hydraulic and / or electrical means, which are referred to as a positioning device or, as far as the patient is being raised, as a lifting device.
  • Support arms that can be pivoted about an axis running approximately parallel to the longitudinal axis of the patient have also been proposed a long time ago.
  • the support arms can be moved around two separate longitudinal members of a frame which can be moved over a bed.
  • Each of the support arms consists of a suspending shank and a support member for the patient's body. These two parts can be pivoted relative to one another and can be locked in two positions, namely perpendicular to one another (to form the angled operating state) and in the extended position.
  • a pin engaging in a bore serves for this purpose.
  • the support arms also each have two joints, the articulated connection, via which the support elements are articulated, having a stop, by means of which the articulation movement in a certain position, in which the support elements are approximately vertical to the subsequent section of the arms is limited.
  • DE-A-1 541 340 describes a device which primarily serves to reduce the radiation exposure of the nursing staff when dealing with radiation-exposing patients. It has a plurality of rigid support arms which are pivotally attached via a swivel joint to a cantilevered support which runs over the longitudinal axis of the patient.
  • the invention is based on the object of providing a device for positioning (in particular for lifting) patients or medical auxiliary objects, which is easy to handle and is gentle on the patient.
  • the object is achieved by a device according to claim 1.
  • An essential basis of the invention is the knowledge that a simpler handling of the device for the nursing staff, but above all a gentler and more comfortable lifting or positioning of the patient can be achieved if the support arms are movable such that they are horizontal or depending on the position of the Patients can be pushed under the patient at different angles of inclination to the horizontal, and the height of the insertion movement (in relation to the surface of the bed) can also be adapted to the patient's lying position.
  • This makes it possible to use the support elements (which in turn correspond to the application can be designed differently) with little effort and gently in each case in the optimal position. This is not guaranteed in the previously known constructions, which only allow a pivoting movement of the support arms about a fixed axis.
  • the infinitely variable lockability allows the support elements to be held in the most comfortable position for the patient. After all multi-articulated support arms have been locked, the patient is brought into the desired position using the positioning device.
  • the joint lock is actuated by means of an auxiliary energy source (in particular electrically, hydraulically or pneumatically).
  • a central actuating element is preferably provided for locking the joints of the support arms.
  • Both simple articulated joints (with one degree of freedom of the joint) and more complex universal or ball joints (with two or three degrees of freedom) can be used as joints.
  • the individual joints preferably each have only one degree of freedom and are therefore structurally relatively simple and reliably lockable.
  • the joint axes of the joints of a support arm usually run parallel to one another. In order to enable more complicated adjustment options, it can also be expedient to use joints on a multi-joint support arm with axes running in different spatial directions. Not all support elements need to be attached to multi-link arms.
  • the lockable joints are preferably designed such that the two are connected to one another via the joint Joint elements each have locking surfaces which slide on one another during the joint movement. Such a joint is locked in that the locking surfaces are pressed against each other.
  • the locking surfaces are preferably provided on interlocking disc disks that can be rotated relative to one another about a common axis, which overall form a disc pack. According to a further embodiment, it is advantageous that the disks are designed as perforated disks with a central recess. In general, annular locking surfaces are preferred, in which the contact forces concentrate on areas that are relatively remote from the axis.
  • this joint construction is also of importance in the medical field, in particular for positioning auxiliary objects with the aid of a support arm comprising several lockable joints.
  • the patient lifting device 1 shown in FIG. 1 has a base part 2, a lifting device designated as a whole by 3 and eight multi-articulated support arms 4, at each end of which a support element 5 is fastened, which is preferably designed as a flat curved slat that can be easily bent can slide under the patient 6.
  • the support elements provided for the different body areas of the patient can be designed differently.
  • the base part 2 can be moved on rollers 7.
  • the lifting device 3 has a carrier 8 designed as a longitudinal beam, which is connected to the base element 2 by means of a parallel guide 9 and a lifting drive 13.
  • the parallel guide 9 consists of a parallel frame 10 rigidly coupled to the support 8, which is guided in two support columns 11 with a roller or slide bearing (not shown) such that it remains in a substantially horizontal position when it is lifted up by the lifting drive 13. or moving down.
  • a pneumatic piston is shown as the lifting drive.
  • the carrier 8 does not necessarily have to be parallel in the strict sense.
  • a certain pivoting component in which, for example, the part of the carrier facing away from the base part 2, to which the support arms 4 for the head region of the patient are fastened, is raised or lowered more, may even be advantageous.
  • a cantilevered support 8 for the support arms 4 which is supported and fastened only on one side. This facilitates both the construction and the handling of the device.
  • the length of the longitudinal beam 8 is approximately matched to the length of the patient bed 12.
  • the base part 2 is positioned at the foot end of the bed (not on the long side).
  • the effective length (in the use position above the patient bed) of the carrier 8 is expediently somewhat shorter than the patient bed.
  • Fig. 2 shows that the patient lifting device 1 can advantageously be folded compactly.
  • the base part 2 forms a mobile carriage, which can optionally be closed with side walls not shown in the figure.
  • the longitudinal beam 8 is expediently foldable with three hinges 16.
  • the support arms 4 are placed tightly around the side member 8 and locked in the initial state.
  • the patient lifting device In use, the patient lifting device is brought into the position at the foot end of the patient bed 12 (FIG. 1) in the state shown in FIG. 2 with the carrier 8 folded and the arms applied. Then the side member is folded out. To balance the weight of the carrier 8 and the patient 6, a counterweight 2a is attached to the base part 2.
  • the articulated and easily movable support arms 4 enable the support elements 5 to be easily and successively in the correct position Position brought under the patient's body 6.
  • the support arms 4 are locked (stiffened), the locking device preferably being designed such that all the support arms are locked simultaneously with the aid of a central actuating element, for example by pressing an actuating button 15 provided on the carrier 8.
  • the patient's body can then be lifted using the lifting device 3.
  • the attachments of the support arms 4 to the support 8 (which are referred to below as articulation points 14) as non-lockable joints (in addition to at least two lockable joints per support arm) are formed. Details are explained below.
  • Figures 3 and 4 show details of a particularly preferred implementation of the lockable support arms.
  • the multi-joint support arms 4 each consist of a plurality of links 21a, 21b, 21c which are connected to one another by joints 20.
  • the joints shown are designated 20a, 20b.
  • Their hinged ends form the joint elements 22a, 22b, 23a, 23b connected by the joints 20a and 20b.
  • the joint elements each have a plurality of mutually interlocking circular disks which can be rotated about an axis 24 and which are referred to below as lamellae 25.
  • the interlocking lamellae 25 overall form a lamella packet 26.
  • the disk pack 26 can be pressed together in various ways, for example by threaded bolts running in the center of the axis 24.
  • the locking with the aid of a central actuating operation can be realized, for example, pneumatically or electromagnetically, each joint 20 having a pneumatic piston-cylinder device or an electromagnetic device consisting of armatures and windings, which is mounted (in a manner familiar to the person skilled in the art) in such a way that the disk packs 26 can be pressed together on a central command.
  • a construction should be selected in which the joints 20 are pressed together when the actuating device is at rest and are released by activating the energy source. This can, as is also known to the person skilled in the art, be achieved in that the force for compressing the disk pack 26 is generated by springs and is canceled by the pneumatic or electromagnetic means mentioned.
  • FIGS. 1 and 2 only show the hose 27 with one support arm 4 each. Preferably, however, all support arms 4 are covered with such a hose.
  • the plate packs 26 are compressed by the external air pressure when the air is sucked out of the hose 27.
  • the evacuated state is shown in FIGS. 3 and 4, the tube 27 forming folds.
  • the formation of wrinkles can be largely avoided by using a tightly fitting hose, the material of which has a certain elasticity.
  • 4 channels 28 and cross connections 29 are provided in the support arms so that the hose 27 in the area of the joints 20 is easily and completely evacuated.
  • 1 shows, by way of example, how the vacuum channels 28 of the support arms 4 are connected via vacuum hoses 28a to a vacuum line running in the carrier 8. It is also advantageous if a part of the slats 25, as mentioned above, has central recesses 30 so that only an outer ring 31 forms the locking surface 25a. As a result, with a given contact pressure, the pressure on the locking surface 25a is increased and concentrated in a region which is relatively distant from the axis 24, which leads to a high locking torque.
  • the cavities formed by the central recesses 30 can also be evacuated. This can be ensured, for example, by slots or notches in the outer rings 31, which are not shown in the figure will.
  • the swivel range of the joints is expediently limited by a swivel stop (not shown) in order to prevent the hose 27 from being overstretched.
  • the preferred multi-articulated support arms shown are simple in construction, reliable in function and are particularly easy to clean because they have a largely smooth surface. It may be useful to design the links 21 of the support arms 4 so that their outer boundary is smooth and preferably has a largely uniform diameter.
  • the material of the links 21 of the support arms 4 should be firm and light.
  • the locking surfaces 25a should be designed so that a high mutual friction is achieved.
  • a layered composite of plywood is suitable, for example, in which the individual slats 25 each consist of a thin plywood plate, which is continued in each case in the shaft 32 of the links 21.
  • Plastic materials are also suitable for the links 21 of the support arms, in which case the locking surfaces 25a can be roughened or provided with an adhesive coating.
  • the links 21 are made of metal.
  • the links 21 do not have to be made of one material throughout.
  • a composite, for example made of plastic and metal, is also suitable, the slats 25 preferably being made of metal.
  • the members 21 of the support arms 4 in addition to the hose 27 with further envelopes, which are not shown in the figures.
  • the links 21 can be encased within the tube 27 with a protective layer made of a soft, shock-absorbing material.
  • a protective layer made of a soft, shock-absorbing material.
  • an additional cover can be provided outside the evacuable hose 27.
  • All envelopes expediently surround the support arms over their entire length from the support 8 up to and including the last joint (20c in FIG. 6) to which the support parts 5 are articulated. However, the support parts themselves should remain free.
  • the support arms are preferably articulated in a hanging manner on the longitudinal beam 8 which extends above the patient in the use position, so that a part of the support arms can be brought into a position encompassing the patient from one side in each case.
  • the support arms 4 encompass the patient from his left side and four other support arms encompass the patient 6 from his right side. This increases patient safety.
  • the articulation points 14 of the support arms 4 on the side member 8 are laterally offset relative to its longitudinal central axis L such that the support arms 4 encompassing the patient each cross a plane which runs vertically through the longitudinal central axis L.
  • this is achieved in that the support 8 is cranked and the articulation points 14 are provided on the other side of the longitudinal central axis L, as seen from the side on which they grip the patient 6.
  • a slight force component acts on the support elements 5 in each case towards the patient's body, which increases subjective and objective safety.
  • the articulation points of the multi-joint support arms on the side member 8 have joints which have rotational degrees of freedom around all three spatial axes, so that the support arms hanging from the support 8 can be pivoted in all three spatial directions.
  • Such an embodiment is shown in FIG. 5.
  • joint sleeves 35 made of a rubber-elastic material are inserted, which are held between a web 36 and a clamping ring 37.
  • a horizontal axis 38 engages in the joint sleeve 35, to which the support arm 4 (not shown in FIG. 5) is fastened.
  • This simple construction enables both the desired pivotability about the horizontal axis H (arrow 39) and the degree of pivoting symbolized by the double arrow 40 about an axis parallel to the carrier 8.
  • the third degree of freedom of rotation about a vertical axis is symbolized in FIG. 1 by the double arrow 41.
  • the pivoting movement about the axis parallel to the carrier and about the vertical axis is damped by the counterforce generated by the rubber-elastic joint sleeve 35 and the pivoting range is limited.
  • the pivoting range in the spatial directions mentioned preferably being less than plus / minus 45 °.
  • Figure 6 shows an alternative embodiment of a side member 8 and the attachment of the support arms 4.
  • the support 8 has slide rails 40, on which the support arms 4 can be moved in pairs with skids 42 which engage around the rails 40 such that the pair of support arms 44 tilts on them.
  • the support arms 4 shown in Figure 6 each have only three joints 20a, 20b, 20c, all of which can be locked. If this minimum number of joints is used, the length of the links 21a, 21b between the joints 20b, 20c should each be at least 25 cm. In general, the length of the support arms from the support 8 to the last joint to which the support element 5 is articulated should be at least about 80 cm.
