Description

TECHNICAL AREA

The present invention relates to a return device for returning patients to a nursing bed according to the preamble of claim 1 and a nursing bed equipped with the device according to claim 11.

STATE OF THE ART

Care beds are known from the prior art. Typically, such nursing beds can be adjusted in height and have a mechanism that allows this height adjustment. For example, a scissors system or telescopic bed posts may be mentioned here. The adjustability allows better care of the patients on the one hand and good floor cleaning under the bed on the other hand.

Typically, such beds also include a security border so that the patient can not fall out of bed. The security border can be provided from side rails, as well as from corresponding networks.

However, certain patients have problems with these borders because they feel restricted in their freedom of movement and actually want to leave the bed in the subconscious. In practice, it has been done in the night to move the beds in their lowest position and remove parts of the border. The patient can fall out of bed, but does not hurt himself, because the drop height is extremely low. However, it is difficult to move the sleeping patient back into the bed. Especially with heavier patients, the caregivers often have trouble raising them.

PRESENTATION OF THE INVENTION

Based on the above-mentioned prior art, it is an object of the present invention to provide a device which allows the simplest possible repatriation of the patient in the nursing bed. In particular, the device should be firmly connected to the care bed or integrated.

Such a problem is solved by a return device or patient return device according to claim 1. Accordingly, a return device for returning a patient to the lying surface of a nursing bed comprises a lying element which can be arranged laterally on the nursing bed and can be connected to the nursing bed such that it can swivel about an axis, and an actuation element for pivoting the lying element relative to the nursing bed. The lying element is pivotable from a horizontal position to a first upper position, which lies above the horizontal position with respect to gravity. With such a return device, the patient can move to the lying surface and can then be moved back into the nursing bed by the pivoting of the lying element.

Preferably, the first upper position is a first vertical position, wherein the lying element in this position forms a side wall of the nursing bed. As a result, the return device can be used variously.

The lying element preferably comprises a lying surface, which lies in the horizontal position substantially in the same plane as the lying surface of the nursing bed, so that the two lying surfaces are at the same level. This is advantageous because the patient does not feel a transition when moving from the nursing bed to the reclining element.

The lying element is preferably connected to the nursing bed via a first side edge, and the lying element has a safety net, which is connected to the other side edges of the lying element. The safety net ensures that the patient does not fall out of bed.

Preferably, the lying element is pivotable into a care position, in which case the lying element is located in a second vertical position, which lies with respect to the pivot axis relative to the first vertical position. Consequently, the lying element is in the care position with respect to gravity below the bed surface of the nursing bed. In this position, easy access to the nursing bed is guaranteed.

Preferably, the actuating element is a drawstring, which is in communication with the lying element, so that it is pivoted upon the action of a tensile force on the drawstring.

Preferably, the tensile force is provided by a displacement of the tension band, in particular by the change in length of at least one telescopic element, or the tensile force is provided by a shortening of the tension band, in particular by rolling it.

Preferably, the at least one drawstring is connected at one end to the lying element and communicates with the other end at a connection point fixed to the nursing bed, the drawstring is guided over a roller which is adjustable in height to the connection point, so that is shortened due to this height adjustment of the drawstring between roller and lying element, and that due to the shortening results in the pivoting movement.

DESCRIPTION OF PREFERRED EMBODIMENTS

The FIG. 1 schematically shows a device for returning a patient to the Lying surface 10 of a nursing bed 1. The device can be arranged on the side of the nursing bed 1 and thus increases the entire bed surface. Consequently, the patient has a greater freedom of movement. The device is arranged here on the right side of the bed, but it is also possible to arrange this on the left side or on both sides. It would also be conceivable to arrange the device in the area of bedstead 11 and / or bed head 12.

Next, the nursing bed on the opposite side of the device, so here on the left side, be provided with a safety net, not shown here. Preferably, the nursing bed 1 also has a bed 11 and a bed head 12. As a result, all four sides of the bed are surrounded by a corresponding border provided by the return device, safety net, bed 11 and bed head 12 so that the patient will not be off can fall to the bed.

The device for returning a patient to the lying surface 10 of a nursing bed essentially comprises a lying element 2, which can be arranged laterally on the nursing bed 1 and pivotally connected to the nursing bed 1 about an axis M, and an actuating element 3 for pivoting the bed element 2 relative to Care bed 1 or lying surface 10. The device for returning the patient may be designed so that existing nursing beds us / or hospital beds can be retrofitted or it may be an integral part of a nursing bed. The actuating element 3 is designed so that the lying element 2 from a horizontal position H, as this in the FIG. 1 is shown, in an upper position V1 is pivotable. As the upper position V1 is understood a position in which the lying element 2 is at an angle to the nursing bed 1, so that the patient can be easily rolled back into the nursing bed. This first upper position V1 is in the FIG. 2 shown.

The surfaces on which the patient rests are referred to as lying surfaces. The nursing bed 1 comprises a lying surface 10, which preferably corresponds to the upper side of a mattress 13. The lying element 2 also comprises a lying surface 20. in the horizontal position H, the two lying surfaces 10, 20 are preferably in the same levels, so that there is no obstacle for the patient when he vom Care bed 1 moves on the lying element 2. Consequently, the entire lying surface is enlarged by the lying surface 20 of the lying element 2 for the patient. In the upper position V1, the two lying surfaces are at an angle to each other, wherein the lying surface 20 is above the lying surface 10 with respect to gravity.

In an advantageous embodiment, the lying element 2 with the lying surface 20 is perpendicular to the lying surface 10 of the nursing bed, so that the lying element 2 can be used as a side wall of the nursing bed. In this position, the upper position V1 corresponds to a vertical position.

The lying element preferably has a rectangular structure with four side edges 21, 22, 23, 24. Preferably, the lying element 2 is connected to the side edge 21 via a joint, not shown here, which permits the pivoting movement.

Furthermore, the lying element 2 can be surrounded by a safety net 4, whereby it is prevented that the patient could fall off the lying element 2. In this case, the safety net 4 preferably surrounds all the side edges 22, 23, 24 of the lying element 2, which are not in communication with care bed 1. The safety net 4 is also stretched over the adjacent bed posts 14 of the nursing bed 1, so that an interior space 40 is created. The interior space 40 extends over the lying surface 20 and has a triangular cross section when the lying element 2 is in the horizontal position. Other types of clamping are also conceivable. When the lying element 2 is pivoted from the horizontal position H to the upper position, the safety net 4 is collapsed by gravity.

With reference to the FIGS. 3 to 6 The three different positions of the lying element 2 relative to the nursing bed 1, in particular relative to the lying surface 10, will now be explained. At the nursing bed after the FIGS. 3 to 6 it is a height adjustable nursing bed, the distance between the bed surface 10 and the bottom B is adjustable. For this purpose, the bed posts 14 telescopic elements 5, which are adjustable in length. These may be hydraulically or electrically operated telescopic cylinders. Preferably, the actuating element 3 is actuated here with the change in length of the telescopic elements 5, as will be explained further below is performed.

In the FIG. 3 is the lying element 2 in the horizontal position H. Also, the nursing bed 1 is in the lowest position. The lowering is advantageous because the patient, if he wants to exceed the safety net 4, can not fall from a large height to the ground B. In this view, it can also be easily recognized that the lying element 2 is connected to the nursing bed 1 via the pivot axis M, and that the two lying surfaces 10, 20 are at the same level.

In the FIG. 4 is the lying element 2 between the horizontal position and the vertical position. It can be well recognized that the safety net 4 moves easily to the lying surfaces 10, 20. This is not critical, since the patient with increasing inclination of the lying surface 20, against which the nursing bed 1 moves. In this figure, it can also be well recognized that the nursing bed can be adjusted in height, so that the distance between the floor B and lying surface 10 is increased. If the actuator 3 is in communication with the height adjustment of the nursing bed 1, the height adjustment is mandatory. Such an embodiment is with the FIGS. 7 and 8 explained in detail. Otherwise, so if the height adjustment of the nursing bed 1 is independent of the actuator 3, an adjustment of the height of the nursing bed 1 is not mandatory, but advantageous because the caregivers have easier access to the patient.

In the FIG. 5 the lying element 2 is completely in the vertical position V1 and thus extends substantially perpendicular to the lying surface 10. In this position, the lying element 2 additionally has the function of a side wall. Furthermore, an increased security can be created by the safety net 4, which lies over the side edge 23 here.

In the FIG. 6 the lying element 2 is in the second vertical position V2 or in the care position. The lying element 2 gives access to the nursing bed and also to the patient free. In order to bring the lying element 2 into this position, the safety net 4 can be separated from the lying element 2 and / or the nursing bed 1.

Regarding the FIGS. 3 to 6 It should also be noted that the bed posts 14 are preferably in communication with a foot plate 15. Preferably, the foot plate 15 extends on the side, which communicate with the device, with the supernatant 16 in the direction of the device. It can be prevented that the nursing bed tilts over the bedpost in the area of the device when a heavy patient comes to rest on the bed surface 10.

With the FIGS. 7 to 10 Two possible embodiments of an actuating element 3 are shown. The actuators can with the embodiments of the FIGS. 1 to 6 be used. In both embodiments, the actuating element 3 comprises at least one tension band 30, which is in communication with the lying element 2. Preferably, two drawstrings 30 are arranged to achieve an ideal distribution of force. A tensile force Z is exerted on the lying element 2 via the two drawstrings 30, so that this is pivoted. The tensile force Z can be provided in various ways. For example, by shortening the tension band 30 or by shifting its end point.

Alternatively, the drawstring can also be replaced by other suitable means. For example, it is conceivable that a rack with a motor or a motor with a corresponding gear provide the pivoting movement.

In the FIGS. 7 and 8 an embodiment of an actuating element 3 is shown, which is coupled to the height adjustment of the bed. The actuating element 3 here comprises a drawstring 30, which is in communication with the lying element 2. The drawstring 30 is then passed over a roller 31 which communicates with the bedpost 14 to the foot 15 of the bedpost. In this case, the foot 15 provides a connection point for the drawstring 30. About a connecting element 32, the drawstring 30 is connected to the foot 15 in a fixed connection. The length of the drawstring 30 is dimensioned so that the lying element 2 lies in the lowest position of the nursing bed in the horizontal.

In an adjustment of the nursing bed 2 in height, the roller 31 is also pushed upwards, which will lead to the pivoting movement of the reclining element 2. The Tensile force Z is thus provided here by a displacement of the roller 31 and thus by shortening the length of the tension band in the area of roller 31 and lying element 2.

In the FIGS. 9 and 10 an alternative embodiment of the actuating element 3 is shown. Again, a drawstring 30 is used, which is in communication with the lying element 2. The drawstring 30 is further connected to a telescopic cylinder 6, which is arranged in the bed post 14. The telescopic cylinder 6 can be adjusted in height, with an adjustment of the telescopic cylinder 6 causes the pivoting of the reclining element 2. The corresponding bedpost here comprises two telescopic cylinders, namely the telescopic cylinder 5 for the adjustment of the height of the bed and the telescopic cylinder 6 for the actuation of the actuating element. 3

In further embodiments, it would also be conceivable if the drawstring on a roll, similar to a winch, would be wound up.

The FIG. 11 2 shows a side view of an advantageous embodiment of the lying element 2. The lying element 2 preferably comprises a rigid frame 25 and a mattress 26 lying on this frame 25. The rigid frame 25 is, for example, a frame assembled from metal profiles. The frame or the frame 25 also includes a pivoting element 8, which is arranged on the side edge 21. The pivoting element 8 can be connected with suitable elements on the nursing bed 1 with the same and then provides the central axis M.

The mattress 26 is preferably detachably connected to the frame 25, so this can be removed in case of possible contamination, but at the same time it is ensured that the mattress 26 does not fall on the patient when the lying surface 20 is in the vertical. Preferably, the mattress is connected via a circumferential zipper or Velcro, and / or via Velcro elements between the mattress 26 and frame 25 to the frame 25.

Further, between the mattress 26 and the frame 25, a sensor 7 may be arranged, which detects when the lying surface 20 is loaded by the patient. By the Output of a corresponding alarm value, the nursing staff can be informed about the falling out of the patient.

The safety net 4 can be connected either to the mattress 26 or to the frame 25, whereby a releasable connection is also the most advantageous here. For example, via a zipper or Velcro.

The mattress 26 of the lying element 2 and the mattress 13 of the nursing bed 1 can be integrally formed, that is, a mattress is present, which extends over the nursing bed 1 and the lying element 2. Alternatively, two separate mattresses can be arranged.
