Description

A device for assisting getting out of bed Technical Field

[0001] This utility model relates to the medical field, specifically to a device for assisting with getting out of bed. Background Technology

[0002] For the elderly, postoperative patients, or people with limited mobility, their movement is restricted, and they need assistance from others or the use of a bed-getting aid to get out of bed.

[0003] Current bed-lowering auxiliary devices mainly suffer from the following two types of technical defects:

[0004] Regarding the stability issues of bed-based compression fixation: Existing bed-setting devices mostly rely on the pressure of the mattress, mattress, and patient's weight for fixation. This design can easily lead to uneven force on the bed surface, resulting in unevenness after long-term use and affecting patient comfort. At the same time, when the patient's weight distribution changes (such as turning over or getting out of bed), the compression effect (fixation force) of the device changes, which can easily cause displacement and pose safety hazards.

[0005] Limitations of Inadequate Handrail Support: Traditional handrail designs often use simple railings or fixed supports, concentrating support at a single point and failing to meet the dynamic balance needs of patients when standing up. For example, some assistive devices provide support through bedside handrails, but the lack of dynamic mechanical support structures at the bottom of the handrails makes it easy for the center of gravity to shift, causing a sudden drop in support when the patient exerts force. Elderly people need to simultaneously transfer their center of gravity and adjust their posture when standing up, but the rigid connection design of existing handrails is difficult to match the biomechanical characteristics of the human body, easily leading to secondary injuries.

[0006] Therefore, there is an urgent need for an improved bed-raising aid device that provides a stable connection and stable support for use. Summary of the Invention

[0007] The purpose of this invention is to provide a device for assisting getting out of bed, which can achieve a stable connection with the bed frame during getting out of bed, getting into bed, and lying in bed, and can be reinforced with the bed frame to provide sufficient support. During the process of getting out of bed and getting into bed, it can provide sufficient dynamic and stable support with the ground, thereby improving safety.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A device for assisting getting out of bed includes a fixed plate, a support frame, and handrails. The fixed plate can be detachably connected to an existing bed frame via a docking assembly. The handrails are connected to the fixed plate via the support frame at positions corresponding to the bed edge. An adjustment structure is provided at the bottom of the support frame. A trigger is provided on the handrails and / or the support frame, and the trigger is connected to the adjustment structure. The trigger moves to drive the adjustment structure to increase its contact area with the ground.

[0010] Compared with the prior art, the bed-lowering auxiliary device adopting the above technical solution has the following beneficial effects:

[0011] Compared to conventional bed-getting aids, the bed-getting aid device of this invention increases the load-bearing support surface through a fixed plate adapted to the bed frame, and reinforces the connection at the edges and bottom of the bed frame through docking components. This achieves dual fixing functions of large-area support and multi-point support, effectively increasing the stability of the device in various states during daily use (getting out of bed, getting into bed, and lying in bed), improving the level of safety and providing sufficient support structure for the user.

[0012] Meanwhile, during getting on or off the bed, the trigger structure that is touched during operation, as well as its linkage with the adjustment structure, can automatically provide sufficient support structure / support surface at the bottom of the support frame, thereby achieving a synchronous dynamic mechanical support effect during getting on or off the bed, so as to further ensure the safety and stability of the user.

[0013] Preferably, the docking assembly includes two docking seats and two connecting pieces. The two docking seats are symmetrically arranged on both sides of the fixed plate, and the connecting pieces are located at the ends of the docking seats away from the fixed plate. One connecting piece can be inserted and fixed to the other connecting piece. By controlling the connection between the docking seats and the edge of the bed body, and by connecting them with each other through the connecting pieces, the fixed plate and the docking assembly can achieve a circumferential reinforcement connection of the bed body.

[0014] Preferably, the connecting piece is composed of multiple sleeved support pieces. By using sleeved support pieces, the connecting piece can be extended or retracted, allowing it to be shortened as a whole to accommodate the need for a connection under the headboard.

[0015] Preferably, the fixing plate has at least two mating seats on the side away from the support frame, and the lower side of the fixing plate and the inner side of the mating seats are provided with anti-slip layers. The frictional resistance provided by the multiple mating seats and anti-slip layers provides multiple support points at the edge of the fixing plate, thereby further increasing the support effect and the stability of use.

[0016] Preferably, the docking seat is divided into a first half and a second half. The first half is rotatably connected to the fixed plate, and the second half is connected to the first half via a pull rod, with a spring between the pull rod and the first half. For beds with different bed board heights, the second half can be directly pulled and fixed to adapt to the bed, effectively increasing its flexibility and versatility.

[0017] Preferably, the adjustment structure includes an extension seat, a movable rod, and a reset member. The trigger member is movably disposed on the upper side of the handrail, the movable rod is movably disposed on the support frame, and the movable rod is connected to the trigger member. The bottom of the support frame is provided with a movable groove for the extension seat to enter and exit. There are two extension seats, and the two extension seats are arranged facing each other. The lower end of the movable rod and the end of the extension seat near the support frame are both provided with ramps. The extension seat is connected to the support frame through the reset member.

[0018] Preferably, the reset component includes an adjusting rod and a reset spring. The adjusting rod is connected to the inside of the support frame through the reset spring, and the adjusting rod is connected to the extension seat.

[0019] By utilizing the guiding effect of the ramp and the resetting effect provided by the return spring, pressing down or releasing the feedback device can drive the two extension seats to gradually extend or retract from the bottom of the support frame. When extended, the support surface at the bottom of the support frame is expanded, providing sufficient support for users when getting on and off the bed via the handrail, depending on the pressure applied. In addition, when the extension seats are retracted, the space occupied at the bottom of the support frame is reduced, so as not to excessively affect the movement of others around the bed.

[0020] Preferably, the bottom of the extension seat is provided with a thin elastic layer, and the elastic layer has an arc-shaped surface on the side facing the support frame. When the extension seat is extended, the elastic layer will gradually extend and contact the ground to increase the frictional resistance between the extension seat and the ground. When retracted, the guiding effect of the arc-shaped surface can apply part of the force to the elastic layer to facilitate the retraction of the elastic layer.

[0021] Preferably, the handrail is provided with a gripping strip at the position corresponding to the trigger, the gripping strip has multiple finger grooves, and the finger grooves have a compression layer inside. The combination of the finger grooves and the compression layer increases the frictional resistance for the patient's gripping operation when getting on and off the bed, and achieves a restraining effect on the hand, thereby increasing the safety level during use.

[0026] The present invention will now be further described with reference to the accompanying drawings.

[0027] The step-down aid device shown in Figures 1 to 3 includes a fixed plate 1, a support frame 2, and a handrail 3.

[0028] The size and specifications of the fixing plate 1 are adapted to the bed frame, and the fixing plate 1 can be detachably connected to the existing bed frame through the docking assembly 4.

[0029] The docking assembly 4 includes a docking seat 40 and a connecting piece 41. There are two docking seats 40 and two connecting pieces 41. The two docking seats 40 are symmetrically arranged on both sides of the fixing plate 1. The connecting piece 41 is located at the end of the docking seat 40 away from the fixing plate 1. One of the connecting pieces 41 can be inserted and fixed with the other connecting piece 41.

[0030] To facilitate the flipping and reconnection of the connecting piece 41, the connecting piece 41 is composed of multiple support pieces 42 sleeved together. In this embodiment, the two connecting pieces 41 are connected by the insertion of the support pieces 42 of two different connecting pieces 41. For example, the end of the support piece 42 furthest from the support frame 2 on the left has an elastic insert, and the end of the support piece 42 closest to the support frame 2 on the right has a slot.

[0031] Furthermore, to further increase stability, at least two docking seats 40 are provided on the side of the fixing plate 1 away from the support frame 2. The lower side of the fixing plate 1 and the inner side of the docking seats 40 are provided with anti-slip layers (such as thin silicone or thin rubber).

[0032] To accommodate bed boards of different thicknesses, the docking seat 40 is divided into a first half seat 43 and a second half seat 44. The first half seat 43 is rotatably connected to the fixed plate 1, and the second half seat 44 is connected to the first half seat 43 via a pull rod 45. A spring is provided between the pull rod 45 and the first half seat 43.

[0033] The handrail 3 is connected to the fixed plate 1 at the position corresponding to the edge of the bed via the support frame 2. The bottom of the support frame 2 is provided with an adjustment structure 5. The handrail 3 and / or the support frame 2 have a trigger 6, and the trigger 6 is connected to the adjustment structure 5. The trigger 6 moves to drive the adjustment structure 5 to increase the contact surface with the ground.

[0034] The adjustment structure 5 includes an extension seat 50, a movable rod 51, and a reset component.

[0035] The trigger 6 is movably mounted on the upper side of the handrail 3, and the movable rod 51 is movably mounted on the support frame 2. The movable rod 51 is connected to the trigger 6. The bottom of the support frame 2 is provided with a movable groove for the extension seat 50 to enter and exit. There are two extension seats 50, and the two extension seats 50 are arranged facing each other. The lower end of the movable rod 51 and the end of the extension seat 50 near the support frame 2 are both provided with ramps 52. The extension seat 50 is connected to the support frame 2 through a reset member.

[0036] In this embodiment, the outer side of the extension base 50 is a triangular structure, and when the extension base 50 extends outward, a triangular stable structure is formed at the bottom of the support base.

[0037] The reset component can be a spring structure or an elastic block structure. In this embodiment, the reset component includes an adjusting rod 53 and a reset spring 54. The adjusting rod 53 is connected to the inside of the support frame 2 through the reset spring 54, and the adjusting rod 53 is connected to the extension seat 50.

[0038] In addition, to increase frictional resistance and further enhance support, the bottom of the extension base 50 is provided with a thin elastic layer 7, and the side of the elastic layer 7 facing the support frame 2 is provided with an arc-shaped surface 70.

[0039] In addition, to increase the stability when gripping the armrest 3, the armrest 3 is provided with a gripping strip 8 at the position corresponding to the trigger 6. The gripping strip 8 is provided with multiple finger grooves 80, and the finger grooves 80 are provided with a compression layer 81 inside.

[0040] Before lying down, first place the fixing plate 1 between the bed board and the mattress, then flip the docking seat 40, pull the multiple support pieces 42 in the connecting piece 41 to extend the length of the connecting piece 41, and insert and fix the support pieces 42 of two different connecting pieces 41 to achieve assembly with the bed frame.

[0041] When preparing to get out of bed, the user's hand grips the grip bar 8, and the hand is temporarily placed in the finger groove 80 by the compression layer 81. When the hand applies force, the feedback device is forced to push down the movable rod 51. Due to the guiding effect of the ramp 52, part of the force is applied to the ramp 52 of the extension seat 50. The extension seat 50 and the elastic layer 7 are forced to extend from the bottom of the support frame 2, realizing the extended support function of the bottom of the support frame 2. As the applied force gradually increases, the support surface provided by the extension seat 50 also increases synchronously. When the hand is removed from the armrest 3, the return spring 54 and the adjusting rod 53 cooperate to pull the extension seat 50 back to its original position. With the guiding effect of the ramp 52, the movable rod 51 and the feedback device are also reset, ready for subsequent use.

[0042] The above description is a preferred embodiment of the present utility model. For those skilled in the art, several modifications and improvements can be made without departing from the principle of the present utility model, and these should also be considered within the protection scope of the present utility model.
