Patient reversing device for the bed

The present invention relates to a patient turning device for a bed, in particular for a hospital or nursing home bed 5, with a sheet interposed between two rollers, each opposite side or end of the sheet being wrapped around the other roll, each roll connected to a drive device, preferably an electric motor drive, for rotating the rollers to wind the sheet from one roll to the other in either direction, preferably for turning a person lying on top of the sheet, and wherein the sheet rollers are mounted at each end on columns provided with at least one articulated member, in particular on the side of the bed 15, calculation by turning with respect to the articular organs.

Thus, it is known that hospital or nursing home beds in particular are provided with a sheet on which a patient with reduced mobility or a person in a nursing home who has difficulty moving, for example due to a stroke, lies, and such a person is turned by moving the sheet transversely. One condition for turning in this way is that the rollers 25 must be arranged at a suitable height relative to the sleeping position of the person on the sheet.

However, in addition to the advantage it offers, this solution has some disadvantages, namely that the rollers have to be placed relatively low, partly because the medical staff can come close to the patient in bed, partly because of the operating mechanism itself, which is impractical to place too high in the bed. also on the road, as it nevertheless requires quite a lot of space.

2,84975 It is therefore an object of the present invention to improve these conditions. According to the present invention, this is achieved in that the columns are preferably located in the vicinity of the end ends of the bed, and in that the bearing supports in the columns are arranged laterally with respect to the longitudinal axis of the columns, the bearing supports being folded around the articulation members. some distance inside the facilities-10 or entirely inside the facilities.

An additional structure to this is that in order to better fasten the articulation mechanisms, the articulation parts are connected to a sliding locking mechanism comprising a locking block, which can be fastened to at least one sliding position by means of a gripping or fastening part. Such a gripping or fastening part may be a quick-release part comprising a spring or it may be a hand-operated clamping part which, for example, holds the parts moving by screw tightening together.

An alternative alternative structure, which may be advantageous in that the rollers are moved more or less when the articulation mechanism is used, is based on the above that the articulation parts are arranged to connect the column parts, one or both of which are telescopic.

The invention will be described in more detail below with reference to structural examples and with reference to the drawings, in which Figure 1 is a perspective view of a bed provided with a device according to the present invention; Figure 2 is a perspective view of the device of Figure 1 not attached to the bed; as Fig. 2, but the rollers are shown in the down position, Figs. 4 and 5 show the combined structure of the ni-35 from the end and from the axial direction of the respective roll, and> i 3 84975 Fig. 6 shows the sliding locking mechanism in vertical section through an articulation device having a horizontal axis and with the roll in question shown in its upper position.

5 In the different figures of the drawing, the same parts or parts performing the corresponding function are denoted by the same reference numerals.

To illustrate the applicability of the invention, the pre-10 device according to the invention shown in perspective in Fig. 1 is placed, for example, on a wheeled bed with ends 2 and side parts 3, only one of which is shown in Fig. 1. Fork-shaped holding parts are placed on top of the side parts 3. which can be locked below the side parts 15 3 with fastening screws or pins 14 inserted into the holes 13 in the side parts 3, columns 7, 8 with a bearing part 6 for a bearing pin 5 at the end of both rollers 4 around which a sheet extending over the bed is wound 1 side sections. The rollers 4 are arranged to rotate and are driven by actuators 10, for example one actuator for each roll. The actuators can be of any construction, manual, hydraulic, pneumatic or electrically operated. They should normally be of a type which allows either full or partial self-locking when not rotating, so that the sheet 1 is fixed when applied to the selected winding position on the rollers 4.

The idea of the device according to the invention is to improve such a telecommunication device so that the roller device, which is used without using a motor, can be raised and lowered relatively simply without great muscle force, so that the patient can be easily brought to and from bed. In this case, it should be noted that hospital or nursing home beds ____ are most often significantly higher than beds used in dwellings 35, precisely because nursing staff can treat patients in the most comfortable 4,84975 working position. It is also a disadvantage of the known telecommunication devices that they are uncomfortable for the patient lying in bed when he has to be lifted out of the bed or moved back to it, because the patient then has to handle too much and is often used by many nursing staff.

The device according to the invention comprises in a basic structure an articulation device 9, which preferably, but not necessarily, has a horizontal articulated shaft connecting two pillar parts 7 and 8 of the pyl-10, which are on fork-shaped holding parts. A simple locking device, for example a hook mechanism, can be arranged to hold the column parts 7 and 8 in one or more working positions. The advantage of the articulation device is that the sheet does not have to be treated relative to the rollers 4 in order to place the rollers 15 4 in an advantageous position, so that it is easy to get out of the bed and move back into it.

Figures 2 and 3 show the same device as in Figure 1, but without the bed. In Fig. 2 the device is shown in the same position as in Fig. 1, while in Fig. 3 the hinge parts 20 are shown lowered.

Fig. 6 shows a section of the column 7, 8 in the same position as in Fig. 1 or Fig. 2. In this case, it can be seen that the column parts 7, 8 are hollow on the inside. The hollow of the part 8 can also be seen in Fig. 3. Inside the columns 7, 25 8 is a sliding locking mechanism, preferably precisely dimensioned in the hollow part of the column 7 and the hollow part 15 of the column 8, i.e. sliding up and down, shown here. provided with a guide or threaded hole for the gripping or holding part 12, which has an operating handle on the outside, which is clearly shown in Fig. 1, Fig. 2 and Fig. 3. On the side of the column part 7 there is, for example, a keyhole-shaped opening 11 clearly marked in the figures and shown by the dotted line in Figure 6 because it is 35 in this figure in front of or behind the section plane. The gripper or holder part 12 is here thought to be provided with a threaded pin 84975 which can be screwed into the lock block 16 from the opening 11. When the lock block reaches the position shown in Fig. 6, the thicker part of the gripper or holder part can be screwed into the widest part of the keyhole opening 11 and fixed the locking block non-slip, i.e. to the position shown in Fig. 6, so that the articulation can take place without hindrance. By moving the locking block 16 downwards, when the gripping or holding part 12 has been removed, in the hole 15 in the position shown in Fig. 6, the parts 7 and 8 remain stationary to each other. This arrangement can also be used when the parts 7 and / or 8 have wall parts formed as a telescopic structure.

Fig. 4 of the drawing shows an alternative structure of the articulated parts 9, which also allows, namely 15 additional fastening parts already known per se, to slide up and down independently of the articulation. The hinge part 9 is replaced here by a horizontal pin 19 which is held in place by side parts attached to the column part 7, not shown in more detail, 20 through which an hook-like part 20 is inserted through the opening between this pin 19 and the column part 7. with the part 20 on top of the column part 7. The height of the pin 19 above the column part 8 determines how much the column part 7 can lower relative to the column part 8 and then also to the bed. The groove part 22 on the column part 8 holds the hook head 21 in place when the column part 7 is in a vertical position. It is also conceivable to use other ways of arranging an upward and downward sliding movement of the part 7 cooperating with the hinge part 9 relative to the part 8, also corresponding parts which allow an oblique sliding movement instead of an upward and downward sliding movement. It should therefore be noted that the length of the hook part 20 between the part 7 and the groove part 22 allows the oblique 35 of the part 7 to slide relative to the part 8, depending on the length of this elongate part 20.

Fig. 5 of the drawing shows a structure corresponding to Fig. 4. Here, however, the groove part 22 is replaced, for example, by the upper edge of the column part 8, by means of which the hook part 23 of the column part 7 can be made to hang when the column part 7 has not been turned outwards.
