Sliding transfer device

The present invention relates to a device for transferring a patient from one location to another. More particularly, the invention comprises a sliding device for moving a patient from one location to an adjacent one, such as from a bed to a wheelchair.

Known device described in U.S. Pat. 519290.

People with limited physical capabilities often have difficulty moving from one place to another. Such people are often strapped to a stroller and need help getting from a bed, bath or seat to a stroller or similar device.

Usually, patient transfer is accomplished by means of transfer boards, which are, as a rule, solid, smooth, rectangular plywood boards, approximately 8 inches wide by 24 to 30 inches long (1 inch = 25.4 mm). For example, to move the patient from the bed to the wheelchair, one rectangular end of the transfer board is placed under the patient sitting on the edge of the bed and the other end of the board is placed on the wheelchair chair. Usually, with the help of at least one person, the patient slides the board from the bed toward the stroller. The patient then sits on the edge of the wheelchair, half-turns his back to the wheelchair, and then the transfer board is removed.

This operation usually requires considerable patient effort and strength. If the patient does not have the strength required for the disabled and the elderly, more than one person is needed to help the patient slide the transfer board. But it becomes a problem when a disabled person or, as is usually the case, an elderly person has to help.

The object of the present invention is to significantly reduce the amount of assistance needed to move a patient or disabled person from one place to another. A further object of the invention is to reduce the degree of patient rotation during resettlement. These and other objectives are achieved by the sliding transfer board described below.

The present invention relates to a generally rectangular or curved sliding transfer device. In one embodiment, the device comprises an upper seat slidably attached to a lower support plate having a flat upper surface. For example, to move the patient from the bed to the wheelchair, one end of the lower support plate is placed under the patient on the edge of the bed. The upper chair moves with the patient. The patient sits on the upper chair and, by means of a sliding chair, is carried by the upper surface of the lower panel towards the edge of the wheelchair chair. At the wheelchair chair, the patient turns his back to the wheelchair with much less effort than with the boards currently in use. The sliding transfer device is then removed from under the patient.

In another embodiment, the upper surface of the lower support plate is curved or has one or more arcs. To move the patient, one end of the lower plate and the chair are placed under the patient on the edge of the bed, the other end is placed on the edge of the wheelchair. In this embodiment, the sliding transfer device is positioned between the bed and the wheelchair chair so that the patient slides on the top of a curved surface, the patient's back facing the back of the wheelchair chair. Thus, in this embodiment, the patient only needs to turn his back slightly in the wheelchair seat, thereby reducing the difficulty of transfer.

In another embodiment, the upper portion of the lower support portion has an S-shaped curvature at both ends, the central portion remaining rectangular or slightly curved. The patient is transferred as described.

In yet another embodiment, the upper seat is slidably secured to the lower support member by means of an articulated joint. The hinged joint facilitates patient displacement as it allows the chair or support plate to rotate freely as the patient moves in or out of the chair. The swivel joint can be used in any version of the lower support plate.

In another embodiment, the seat comprises flexible members that can be used to aid patient movement. The flexible elements are used to place the chair under the patient and protect the patient's clothing or patient's body from being trapped between the upper chair and the lower panel. This seat can be hinged or other combinations with different versions of the lower support plate can be used.

FIG. 1 illustrates one embodiment of a sliding transfer device. This variant has a flat, rectangular top surface having a lower support plate 1 and an upper seat 2. The upper seat is 6-pivotally attached to the lower support part due to the cancer-guiding structure. In this embodiment, the track 3 has an internal notch extending along the support plate. As shown in Figs. 4, the outer guide 4 is placed inside the cut gauge 3. The adjustable tension screw 5 can be used to additionally attach the upper seat 2 to the lower support plate 1 and to control the movement of the seat along the lower support plate. The locking plates 6 and 7 can also be mounted at each end of the lower support plate to retain the upper seat in the cutout track. The locking device 8 guarantees patient safety and controls the movement of the seat 2.

During use, the lower support plate 1 is placed on the edge of the bed 9 and on the edge of the wheelchair 10. When moving from the bed to the wheelchair, the patient sits on the upper chair 2. The patient is transported from the bed to the veLT 3500 B pellet, with the upper chair 2 sliding on the upper surface of the lower support plate 1. Because the upper seat slides, the patient needs significantly less help moving from one place to the next.

FIG. 2 illustrates another embodiment of the invention comprising a curved lower backing plate 21. In this embodiment, a curved upper seat 22 is slidably secured to the support plate 21 by a track and a guide. The track 23 is also correspondingly curved as the lower support plate 21. The adjustable tension screw 25, the locking plates 26 and 27 and the locking device 28 can also be used as in Figs. 1 variations.

When moving the patient from the bed to the stroller, one curved end of the lower support plate 21 is placed beneath the patient on the edge of the bed 29 and the other end is placed on the edge of the stroller chair 24. The patient usually sits on the seat 22 with his back facing the convex portion of the curved lower support plate and his feet resting on the convex portion of the lower support plate. The patient is transported from the bed to the stroller seat because the upper seat 22 slides in a curved path consisting of a cut gauge 23. When the seat 22 moves in a curved gauge 23, the patient's back is facing the stroller seat 24. Thus, in this embodiment less help putting it in a wheelchair.

The lower support plate preferably has a large radius of arc. However, any hoop or combination of hoops that will help the patient sit down may be used. Further, the curvature of the outer surface may be different at different points on the lower base plate. In this way, the curved lower support plate may have a large radius arc at one end and a small radius arc at the other end. In this case, the patient will be assisted even further by a steeper turning of the seat of the device at the wheelchair. In addition, the curved lower support may have two smooth arcs, which may be at opposite ends, as shown in FIG. 7 or 8.

FIG. 3 is an exploded view of a sliding transfer device. In this embodiment, the upper seat 40 is slidably mounted on the lower support plate 41 by a guide track 43. The routing wheels 42 may be attached to the underside of the seat 40 to reduce friction between the seat and the lower panel. Other measures to reduce friction between the upper seat and the lower support plate may also be applied. For example, a deflected deflection track may be provided with bearings, or a deflection track mounted to the underside of the upper seat may be provided with outer bearings. Alternatively, a simple ball bearing of appropriate size may be positioned at the bottom of the deflector for subsequent friction reduction.

The lower support plate and the upper seat may be constructed of any suitable material, such as wood, metal such as stainless steel or aluminum, plastics such as nylon or organic glass, or combinations thereof. Handles may also be provided to control the bottom plate and the sliding transfer device.

The seat can be in any suitable shape. In this way, the seat may be concave in the middle, but extending down to the edges. This configuration will allow the patient to slide the device and protective clothing and the patient's body from being trapped when the seat slides on the lower support surface. The seat may also have flaps at one or more ends, flexible or raised, which further protect the patient's clothing or body parts. The handles are mounted in flexible flaps as shown in FIG. 8th

The seat can be attached to the lower support plate by any means. Preferably, the seat is secured by means of a deflector and track means so that the seat slides along the upper surface of the lower support plate. Other sliding mechanisms known from the above may also be used. Such mechanisms may include, for example, rails, protrusions, rollers, or combinations thereof. In this way, the track may be placed on the lower support plate, which is better, or may extend over the lower support plate.

FIG. 5 illustrates the arrangement of a hinged seat of the present invention consisting of an upper seat 52 rotatably attached to a lower support plate 51 by means of a hinged link 52. The swivel facilitates patient transfer because it allows either the upper chair or the lower panel to rotate freely as the patient moves onto the seat. In this way, the patient chair can move much more easily since both the chair and the lower back plate can be maneuvered. As the patient is moved, the hinge allows the chair to rotate the patient. For example, if the patient is to be moved from a bed 59 to a wheelchair 60, the hinged connection 55 allows the upper chair to be easily positioned beneath the patient by rotating either the lower support plate 51 or the upper chair 52, or a combination of both. When the patient is moved, the articulation 55 allows the upper chair 52 to rotate and orient the patient's back toward the back of the wheelchair chair (not shown) and allows the patient to easily slide away from the upper chair. Controls of the degree of rotation and rotation of the seat on the support plate 51, as well as the control of the movement of the seat with the lower support plate, may also be used.

The lower support plate 51 in this embodiment of the invention may be of any of the shapes herein, including rectangular curved or any combination, and the upper seat formed accordingly. In addition, the track 53 is shown as an internal notch suitable for a pivot joint 53, but any cancerous structure suitable for the pivot joint may be used.

Any previously known articulation may be used. Fig. 6 illustrates one such mechanism, wherein the pivot joint 53 is formed by a pin 60 and a wedge-shaped groove 62. The locking devices 58 and locking plates 56 and 57 may also be used to ensure patient safety and control the upper swivel chair 52. In this way, the torsion mechanism can be adapted to the track located inside or above the lower support plate.

FIG. 7 illustrates an additional embodiment of a sliding transfer device wherein the lower support plate 71 has S-shaped curved portions 72, 73 at both ends. The S-shape may be directed forward or backward to form any shape in which the ends of the support plate are curved in opposite directions. The center portion 74 of the lower support plate 71 may, at best, be rectangular or curved in any direction. The track 75 is inside and conforms to the shape of the lower support plate 71. The elements 76, 77 described are also acceptable. The backing plate may lie between two transfer locations, such as the edge of the bed 78 and the carriage 79, and is controlled as described above.

Okay

FIG. Fig. 8 illustrates an additional embodiment of the present invention mounted on the seat of Figs. 7 shows the lower support plates. The upper seat 80 has flaps 82, 83 disposed at opposite ends of the seat 80, and the sheets may be flexible or secured so that they can be raised or lowered as required. The flaps may also have openings for the arms 84, 85. The flexible flaps help to place the chair under the patient and protect the patient's clothing or body parts from being trapped between the upper chair and the lower support plate when the patient is lifted from the bed 86 to the stroller. The upper seat shown in Fig. 8 may be any lower support plate may be installed in any one of the most preferred technical uses with the variant and described.

Embodiments of the embodiments include installing an upper chair on the lower support plate 81. 6 due to the articulated mechanism.

The invention includes additional devices, such as a belt about 20 to 30 inches wide, that can be used to hold the patient on a chair. In addition, handholds may be provided at appropriate locations on the seat and the lower back plate for patient safety. Finally, the lower support plate may be formed on a support structure such as a perforated metal structure 54 shown in FIG. 5. In this embodiment, the plastic or similar material covers a structure that strengthens the device without significantly increasing its weight.

Other means of facilitating the sliding of the upper seat with the lower backing plate are also acceptable. While the aforementioned bearings under the chair and track will reduce friction and facilitate the movement of the chair, additional support may be required. In addition, the patient can get up alone and the assistant device will reduce the patient's effort.

One such accessory is a small electric motor that can run on batteries or be recharged. The engine is housed in a support deflector to supply the energy needed to slide the upper chair from one end of the lower support plate to the other. In this way, a small toothed wheel may be placed near the base of the plate to engage the serrated belt placed inside the track. The seat moves with the support plate as the engine turns the gear. Other known auxiliary aids, such as various spring attachments, may also be used.
