Definitions

  • the present invention relates to the handling of a patient or a cripple and its transport when moving from one layer to another in a hospital establishment.
  • the manipulations considered require the participation of several people and a significant physical effort of them. These manipulations are accompanied by jolts and often put the patient in undesirable postures for the latter.
  • the purpose of the present invention is to allow a single person and without significant physical effort, to ensure the transfer of the patient from his bed to another layer (radiology table, operating table, ambulance stretcher or other trolley ), this invention having, during transport proper, the same qualities as a conventional trolley.
  • the invention relates to a hospital trolley comprising a movable base resting on the ground and a structure whose level relative to the ground is variable, said structure being intended to carry the patient's body, characterized in that said structure comprises a plurality of substantially rigid shelves, only supported by the same beam and capable of sliding, with respect to it, substantially orthogonally to the axis of the patient's body to be transported, said beam being connected to the base by means of adjusting the level relative to the ground.
  • a flap which fills the space likely to be occupied by the sliding shelves when they are in the patient's support position. A substantially continuous layer is then obtained.
  • the flap pivots about a horizontal axis, parallel to the middle line of the beam. This flap can thus retract vertically when picking up and removing the patient.
  • the patient needs to have the upper body and the head raised. It is therefore advantageous for the beam to have two articulations of horizontal axis perpendicular to the mean line of the beam and symmetrically placed with respect to the middle of the beam, means being provided for blocking one or the other at the desired inclination. other end of the beam.
  • the central part is connected to the base by the level adjustment means relative to the ground.
  • the beam can pivot around a horizontal axis parallel to its mean line.
  • the central shelf (s) can be either substantially horizontal, or inclined towards the patient.
  • the horizontal axis and parallel to the mean line of the beam, around which the flap pivots, is connected to the movable base by a support upright formed by two vertical columns parallel to each other, symmetrically placed with respect to the means for adjusting the level.
  • the central part of the beam advantageously comprises openings symmetrically placed with respect to the level adjustment means, in which the vertical columns take place when the central part of the beam is below the level of the vertices of the vertical columns.
  • the seat is made up of a rigid plate on which cushions are placed.
  • the cushions fill the spaces on the plate which may never be occupied by the sliding shelves when they are slid into the patient's support position.
  • the seat is held in a horizontal position by locking knee pads. When the flap is in the vertical position, they retract along the vertical columns of the support upright.
  • the ends of the beam and the central part each support a single sliding shelf symmetrically placed with respect to the level adjustment means when the whole of the beam is horizontal.
  • Fixing means are advantageously arranged in each of the sliding shelves supported by the ends of the beam, allowing to fix a removable headrest.
  • a device has advantageously been provided to prevent the sliding shelves from coming out of their slot. It may include, under each shelf, a groove parallel to its displacement and placed at equal distance from the edges of the sticking shelf orthogonal to the mean line of the beam. These grooves follow a complementary shape placed in relief in each slot. The grooves are closed at their ends.
  • the base has a U shape. Its central part supports the level adjustment means and the support upright.
  • the level adjustment means is a double-acting hydraulic cylinder. This last characteristic makes it possible to compress the mattress of the bed on which the patient rests before it is taken up by the trolley.
  • the carriage consists of a movable base 2-3, supported by four swivel casters 1 each provided with a brake. It may be useful to have a central control of the four brakes.
  • the arms 2 are low enough to be able to penetrate under all types of bed. The spacing of the arms 2 allows them to penetrate around an operating table leg and on the other hand, between the legs of the bed.
  • the tube 4 in which the piston 5 moves is fixed on the central part 3 of the mobile base.
  • the tube 4 could be attached to an arm 2 of the movable base.
  • the displacement of the piston 5 is ensured by a jack hydraulic double acting.
  • the pedal 22 actuates the hydraulic pump and the pedal 23 controls the distributor which reverses the direction of movement of the piston 5.
  • the central part of the beam 6 is connected to the upper part of the piston 5 via the axis 7 which passes through the plate 27 and the support 29 ( Figures 7.a and 7.b).
  • the plate 27 is welded under the beam, the support 29 being fixed on the top of the piston 5.
  • a movable stud 8 ensures the blocking of this rotation by passing through a hole in the support 29 and into the corresponding hole in the plate 27 This blocking can be done when the central shelf 11 is substantially horizontal.
  • the plate 28 parallel to the central part of the beam 11 limits the angle of rotation of the beam 10-11 around the axis 7 to about 30 ° relative to the horizontal.
  • the ends of the beam 12 are connected to the central part 6 by the hinges 9.
  • a device makes it possible to maintain each of the ends 12 at the desired inclination (FIG. 3).
  • a groove provided in each sliding shelf 10 parallel to the axis of its movement takes on a complementary shape 30 placed in relief in the slot. The groove is closed at both ends. All this device prevents each sliding shelf 10-11 from coming out of the slot.
  • the sliding shelves 10-11 are covered on both sides with plastic material with a low coefficient of friction.
  • a variant consists in placing bearings on the upper face of each sliding shelf to reduce friction on the patient's skin.
  • the central part 3 of the mobile base 2-3 supports the two vertical columns 13 symmetrically placed with respect to the tube 4.
  • the flap 16-17 is connected to the top of the vertical columns 13, around which it pivots, by means of the hinges 15.
  • Two openings 34 symmetrically placed with respect to the piston 5 are arranged in the central part 6 of the beam 6-12.
  • the columns of the support upright 13 find a place in these openings 34.
  • the section of the latter is greater than that of the columns so that, even in the low position, the beam 6 -12 can pivot around axis 7.
  • Recesses 35-36 are arranged in the flap 16-17 so that, when the latter is in the vertical position and the beam 6-12 is below the level of the top of the vertical columns 13, the sliding shelves 10 -11 can cross the flap 16-17 to find themselves in the patient's support position ( Figure 2).
  • the recesses 36 corresponding to the sliding shelves 10 are wider to allow, in the position described above, a rotation of the ends 12 of the beam around the hinge 9.
  • Knee pads 14-31 allow, when unfolded, to keep the flap 16-17 horizontal ( Figure 5.a).
  • a spring 32 tends to spread the rod 31 of the flap 16-17.
  • a device, not shown, controlled by a handle, makes it possible to compensate for the effect of the spring 32 by reducing the rod 31 to the flap 16-17 when it is desired to fold it down.
  • the flap 16-17 consists on the one hand of a rigid plate 16 on which are fixed the hinges 15, the rods of the knee pads 31, the guide bars 25 and the barrier 21 and on the other hand, of cushions 17 placed on the rigid plate 16 in the areas likely to never be occupied by the sliding shelves 10-11. Spaces between the shelves 10-11 and the cushions 17 are however left empty in order to avoid pinching of the patient's skin during movement of the sliding shelves 10-11 relative to the cushions 17 when the flap 16-17 is horizontal.
  • the thickness of the vacuum cushions is slightly greater than that of the shelves 10-11, so as to obtain, when the cushions 17 are compressed by the patient's body, an almost flat surface and good weight distribution between the sliding shelves 10 -11 on the one hand and the cushions 17 on the other.
  • a device is provided so that, when the flap 16-17 is in the horizontal position, the descent of the beam 6-12 is automatically stopped when the shelves 10-11 are in contact with the rigid plate 16.
  • the patient's weight is supported both by the vertical columns and by the tube / piston assembly 4-5.
  • the barrier 21 is constituted by a deformable parallelogram which is fixed on the rigid plate 16.
  • FIGs 4.a to 4.i The operation of the device is illustrated in Figures 4.a to 4.i
  • the device is first of all approached the bed 100 in the position illustrated in Figure 1: the flap 16-17 is horizontal and the shelves sliding doors 10-11 form with this a substantially flat layer.
  • the knee lever 14-31 is unlocked and allows the seat 16-17 to be lowered vertically, as shown in Figure 5.
  • the beam 6-12 and sliding shelves 10-11 assembly is then brought to the desired height. using the jack 4-5, by actuating the pedal 22, the pedal 23 controlling the distributor being in the mounted position. This height is slightly greater than that of the mattress 101 of the bed 100.
  • the device is then advanced, putting the arms 2 of the mobile base 2-3 under the bed. This position is illustrated in Figure 4.c.
  • the rotation of the beam 9 around the axis 7 is released by removing the stud 8 from the hole in the plate 27 corresponding to it, allowing the sliding shelves 10-11 to take a position slightly inclined towards the patient. This position is illustrated in Figure 4.d.
  • the sliding shelves 10 and 11 are then slipped one by one under the patient and the headrest 18 introduced into the plate which is located on the side of the patient's head.
  • the pedal 23 is then placed in the descent position and by repeated action on the pedal 22, the beam is lowered by compressing the mattress 101 until the central sliding shelf 11 returns to a substantially horizontal position. When this is reached, the rotation of the beam 6-12 is locked, the stud 8 returning to its initial position in the plate 27. This position is illustrated in 4.f.
  • the beam 6-12 and sliding shelves 10-11 supporting the patient 102 assembly is raised by repeated actions on the pedal 22, the pedal 23 being in the up position. Then the device is moved so as to remove the arms 2 of the base from under the bed 100 mobile 2-3. The flap 16-17 is then straightened to a horizontal position and locked in this position by means of the knee pads 14-31.
  • the beam 6-12, the sliding shelves 10-11 and the patient 102 are lowered to the flap 16-17, by action on the pedal 22, the pedal 23 being in the descent position.
  • the patient 102 then rests on a horizontal and substantially flat layer.
  • the barrier 20 slides vertically in the beam 6 and locks in the high position.
  • the barrier 21 pivots in a plane perpendicular to the mattress 17.
  • the ends 12 of the beam 6 pivot in a vertical plane, with an axis perpendicular to the beam and can lock in various positions. This option allows you to pick up a patient with his head or feet raised, it also allows him to be transported this way.
  • the apparatus described has many advantages. First of all, it offers all the possibilities of a hospital trolley: it allows easy transport, access to the patient all around the trolley, the possibility of adapting basic care devices and sufficient comfort to allow the patient a stay extended on this one.
