A liftable rehabilitation frame for a care bed

Abstract

This utility model relates to the field of rehabilitation therapy technology and discloses a height-adjustable rehabilitation frame for a nursing bed, which includes a top frame and a lifting assembly. The top frame provides a training plane required for rehabilitation training. Since the extension column is fixedly connected to the top frame and slidably connected to the support column, the power end is fixedly connected to the extension column, the moving end is fixedly connected to the cross frame, and the bottom end of the support column is fixed to the cross frame, when the power end drives the moving end to move up and down, the extension column slides relative to the support column, thereby changing the height of the extension column relative to the bed surface of the nursing bed, and thus causing a change in the relative height between the top frame and the nursing bed. Moreover, the two lifting units at the same end in the first direction use the cross frame as a reference when lifting, which facilitates synchronous lifting and lowering, so that one end of the top frame can be adjusted accordingly to adapt to the angle of the nursing bed. This eliminates the need to disassemble and reassemble parts of the rehabilitation frame, reduces labor costs, and improves adjustment efficiency.

Description

Technical Field

[0001] This utility model relates to the field of rehabilitation and physiotherapy technology, and in particular to a height-adjustable rehabilitation frame for a nursing bed. Background Technology

[0002] Nursing beds are one of the main pieces of equipment in the field of clinical medical care. Existing nursing beds can achieve complex positional changes such as backrest lifting (changing from lying to sitting), overall lifting, standing, and even Trendel-Lombard position (Trendel position) and reverse Trendel-Lombard position (reverse Trendel position) to assist in treatment and improve patient comfort.

[0003] To facilitate direct rehabilitation training for patients on their beds, rehabilitation frames are typically installed above the bed and directly mounted to it. The training surface at the top of the frame provides the necessary gripping points or mounting locations for rehabilitation equipment. However, existing rehabilitation frames are fixed, one-piece assembled structures whose overall height and volume cannot be changed. For example... Figure 1 As shown, when a nursing bed, especially one with adjustable standing structure, undergoes a significant structural change from a "flat" position to a "standing" position (i.e., the bed surface is tilted to a near-vertical state), the rehabilitation frame on the nursing bed will rotate with the bed. The tall rehabilitation frame can interfere with the ceiling, indoor lighting fixtures, or other ward facilities, posing a significant risk of collision. The rehabilitation frame needs to be lowered to avoid interference with the existing ward structure. Furthermore, the effectiveness and safety of rehabilitation training are highly dependent on the relative position of the equipment and the patient's limbs; the height of the top beam of the existing support (i.e., the distance between the training plane formed by the rehabilitation frame and the bed surface) is fixed. When the bed is adjusted to the Trästätschler position or reverse Trästätschler position, one end of the nursing bed is higher than the other along its length, correspondingly causing one end of the rehabilitation frame to be higher than the other. This can lead to a certain shift in the gripping points on the training plane or pose a safety hazard due to instability in the center of gravity of the rehabilitation frame.

[0004] Some existing rehabilitation frames are height-adjustable, but if adjustments are needed, tools must be used to disassemble and reassemble parts of the steel pipe structure. This process is cumbersome, time-consuming, and labor-intensive, requiring at least two operators. It also makes it impossible to make quick and flexible adaptive adjustments based on the patient's real-time condition during treatment (such as switching from supine to sitting position), which seriously reduces treatment efficiency and user experience. Utility Model Content

[0005] The purpose of this invention is to provide a height-adjustable rehabilitation frame for nursing beds, which solves the problems of high labor costs and low adjustment efficiency caused by the need to disassemble and reassemble some parts of the existing rehabilitation frame to achieve height adjustment.

[0006] To achieve the above objectives, this utility model provides a height-adjustable rehabilitation frame for a nursing bed, which includes a top frame and a lifting assembly; The top frame is horizontally arranged and extends along a first direction, and the top frame has a training plane for rehabilitation training; both ends of the top frame in the first direction are connected to vertically downward extending lifting components; the two lifting components enclose a training space. The lifting assembly includes a crossbeam and lifting units. The crossbeam is spaced apart below the top frame and extends along a second direction. Two lifting units are spaced apart on the crossbeam along the second direction. The lifting unit includes a support column, an extension column, and a reciprocating mechanism; the support column extends vertically and is used to connect with the nursing bed, and the bottom end of the support column is fixed to the cross frame; the extension column extends vertically, with one end fixedly connected to the top frame and the other end slidably connected to the support column; the reciprocating mechanism includes a power end and a moving end; the power end is fixedly connected to the extension column, and the moving end is fixedly connected to the cross frame. The first direction and the second direction are perpendicular to each other on the horizontal plane.

[0007] Furthermore, the lifting unit also includes a sliding mechanism; The extension column is slidably connected to the support column via the sliding mechanism.

[0008] Furthermore, the sliding mechanism includes a slide rail and a slider; The support column and the extension column are arranged at intervals along the second direction; The slide rail is fixed to the side surface of the support column facing away from the training space, and the slide rail extends vertically. The slider is fixedly connected to the bottom end of the extension column and slidably connected to the slide rail.

[0009] Furthermore, the sliding mechanism also includes a fixing frame; The two sliders are slidably mounted on the slide rail at a distance along the vertical direction; The fixing bracket is sleeved on the outer periphery of the two sliders and fixedly connected to the sliders. The side surface of the fixing bracket away from the slide rail in the second direction is fixedly connected to the extension column.

[0010] Furthermore, the reciprocating mechanism is an electric push rod, the motor of the electric push rod defines the power end, and the push rod of the electric push rod defines the moving end.

[0011] Furthermore, the lifting unit also includes a first connecting member; The first connector is fixed to the top of the cross frame and extends vertically upward. The top of the first connector has a first connecting groove. The end of the push rod away from the motor is inserted into the first connecting groove and connected to the first connector.

[0012] Furthermore, the lifting assembly also includes an auxiliary rod; The auxiliary rods are spaced apart above the crossbeam and extend along the second direction; The two ends of the auxiliary rod are respectively fixedly connected to the two extension columns.

[0013] Furthermore, the top frame includes longitudinal bars and transverse bars; The two longitudinal bars are spaced apart along a second direction and extend along a first direction; each of the longitudinal bars is connected to an extension post at both ends in the first direction. At least two of the crossbars are spaced apart along a first direction and extend along a second direction, and the crossbars are detachably connected to the longitudinal bars; the lower surface of the crossbars defines the training plane.

[0014] Furthermore, the top frame also includes an adjusting element; The adjusting member has a first connecting hole and a second connecting hole; the first connecting hole penetrates both sides of the adjusting member in a first direction; the second connecting hole is spaced below the first connecting hole and penetrates both sides of the adjusting member in a second direction. The adjusting member is detachably sleeved on the outer periphery of the longitudinal rod through the first connecting hole and detachably sleeved on the outer periphery of the transverse rod through the second connecting hole.

[0015] Compared with the prior art, the adjustable rehabilitation frame for nursing beds provided by this utility model has the following advantages: This utility model provides a height-adjustable rehabilitation frame for a nursing bed, comprising a top frame and a lifting assembly. The top frame provides a training plane for rehabilitation training. One end of the extension column is fixedly connected to the top frame, and the other end is slidably connected to the support column. The power end of the reciprocating mechanism is fixedly connected to the extension column, and the moving end is fixedly connected to the cross frame. The bottom end of the support column is fixed to the cross frame. When the power end drives the moving end to move up and down, the extension column slides relative to the support column, thereby changing the height of the extension column relative to the nursing bed. This, in turn, changes the relative height between the top frame connected to the extension column and the bed surface of the nursing bed. Two lifting units are spaced apart on the cross frame along the second direction. When the two lifting units at the same end in the first direction are raised and lowered, they use the cross frame as a reference, facilitating synchronous raising and lowering. This allows for corresponding adjustment of one end of the top frame to accommodate the angle of the nursing bed when the bed is adjusted to a specific or inverse position. This eliminates the need for disassembly and reassembly of parts of the rehabilitation frame, reducing labor costs and improving adjustment efficiency. Attached Figure Description

Detailed Implementation

[0018] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0019] like Figures 2-4 As shown, an embodiment of the present invention provides a height-adjustable rehabilitation frame 100 for a nursing bed, which includes a top frame 1 and a lifting assembly 2. The top frame 1 is horizontally arranged and extends along the first direction X. The top frame 1 has a training plane for rehabilitation training. Both ends of the top frame 1 in the first direction X are connected to vertically downward extending lifting components 2. The two lifting components 2 enclose a training space. The lifting assembly 2 includes a crossbeam 21 and lifting units 22. The crossbeam 21 is spaced apart below the top frame 1 and extends along the second direction Y. Two lifting units 22 are spaced apart on the crossbeam 21 along the second direction Y. The lifting unit 22 includes a support column 221, an extension column 222, and a reciprocating mechanism 223. The support column 221 extends vertically and is used to connect to the nursing bed 200. The bottom end of the support column 221 is fixed to the cross frame 21. The extension column 222 extends vertically, with one end fixedly connected to the top frame 1 and the other end slidably connected to the support column 221. The reciprocating mechanism 223 includes a power end 2231 and a moving end 2232. The power end 2231 is fixedly connected to the extension column 222, and the moving end 2232 is fixedly connected to the cross frame 21. Among them, the first direction X and the second direction Y are perpendicular to each other on the horizontal plane.

[0020] Based on the above technical solution, the top frame 1 provides the training plane required for rehabilitation training; since one end of the extension column 222 is fixedly connected to the top frame 1 and the other end is slidably connected to the support column 221, the power end 2231 of the reciprocating mechanism 223 is fixedly connected to the extension column 222, the moving end 2232 is fixedly connected to the cross frame 21, and the bottom end of the support column 221 is fixedly mounted on the cross frame 21; such that when the power end 2231 drives the moving end 2232 to move up and down, the extension column 222 slides relative to the support column 221, thereby realizing the extension column 222 The height of the nursing bed changes relative to the extension column 222, which in turn causes a change in the relative height between the top frame 1 and the bed surface of the nursing bed. The two lifting units 22 are spaced apart on the cross frame 21 along the second direction Y. The two lifting units 22 at the same end in the first direction X use the cross frame 21 as a reference when lifting, which facilitates synchronous lifting. When the bed is adjusted to the Te's position or the reverse Te's position, one end of the top frame 1 is adjusted accordingly to adapt to the angle of the nursing bed. This avoids the need to disassemble and reassemble part of the rehabilitation frame structure, reduces labor costs and improves adjustment efficiency.

[0021] It should be noted that, in order to adapt to the adjustment of the nursing bed's tert-position or reverse tert-position, in this embodiment, the first direction X is parallel to the length direction of the nursing bed, and the second direction Y is parallel to the width direction of the nursing bed.

[0022] Furthermore, such as Figure 2 and Figure 3 As shown, to specifically realize the sliding connection between the support column 221 and the extension column 222; the lifting unit 22 also includes a sliding mechanism 224; The extension column 222 is slidably connected to the support column 221 via the sliding mechanism 224.

[0023] Furthermore, such as Figure 2 and Figure 3 As shown, the sliding mechanism 224 includes a slide rail 2241 and a slider 2242; The support column 221 and the extension column 222 are arranged at intervals along the second direction Y; The slide rail 2241 is fixed on the side surface of the support column 221 facing away from the training space, and the slide rail 2241 extends vertically. The slider 2242 is fixedly connected to the bottom end of the extension column 222 and slidably connected to the slide rail 2241.

[0024] It is understood that the slider 2242 is slidably connected to the slide rail 2241, and the slider 2242 is fixedly connected to the bottom end of the extension column 222. The slide rail 2241 is fixed to the side surface of the support column 221 facing away from the training space, thereby realizing the slidable connection between the support column 221 and the extension column 222.

[0025] Furthermore, such as Figure 2 and Figure 3 As shown, the sliding mechanism 224 also includes a fixing frame 2243; To improve the stability and reliability of the sliding connection, the two sliders 2242 are slidably mounted on the slide rail 2241 at intervals in the vertical direction; The fixing bracket 2243 is sleeved on the outer periphery of the two sliders 2242 and fixedly connected to the sliders. The side surface of the fixing bracket 2243 away from the slide rail 2241 in the second direction Y is fixedly connected to the extension column 222. Thus, the fixing bracket 2243 connects the two sliders simultaneously, thereby achieving a fixed connection between the extension column 222 and the two sliders 2242.

[0026] Furthermore, such as Figure 2 and Figure 3As shown, the reciprocating mechanism 223 is an electric push rod, the motor of the electric push rod defines the power end 2231, and the push rod of the electric push rod defines the moving end 2232.

[0027] It should be noted that the electric linear actuator is a mature reciprocating motion mechanism; the specific structure of its motor driving the linear actuator to perform reciprocating motion is a mature existing technology, which will not be elaborated here.

[0028] Preferably, the motors of the electric push rods in the two lifting units 22 located in the same lifting assembly 2 are electrically connected to the PLC controller; so that the PLC controller controls the two motors to rotate synchronously, thereby realizing the synchronous lifting and lowering of the two lifting units 22 on the same side in the first direction X. Alternatively, the motors in the four lifting units 22 of the liftable rehabilitation frame 100 for the nursing bed are electrically connected to the PLC controller; so as to realize the synchronous lifting and lowering of the four lifting units 22. Controlling the synchronous or asynchronous rotation of motors and controlling the motor speed through the PLC controller are mature existing technologies. The relevant PLC controller models and specific control processes are not described here.

[0029] Furthermore, such as Figure 2 and Figure 3 As shown, to specifically realize the connection between the push rod and the cross frame 21; the lifting unit 22 also includes a first connecting member 225; The first connector 225 is fixed to the top of the cross frame 21 and extends vertically upward. The top of the first connector 225 has a first connecting groove 2250. The end of the push rod away from the motor is inserted into the first connecting groove 2250 and connected to the first connector 225.

[0030] Preferably, such as Figure 2 and Figure 3 As shown, in order to facilitate the connection of the motor to the extension column 222, the lifting unit 22 also includes a second connector 226; The second connector 226 is fixed to the side surface of the extension column 222 facing the training space; the motor is fixedly connected to the second connector 226.

[0031] Furthermore, such as Figure 2 and Figure 3 As shown, to improve the reliability of synchronous lifting of the two lifting units 22 in the same lifting assembly 2, the lifting assembly 2 also includes an auxiliary rod 23; The auxiliary rods 23 are spaced apart above the crossbeam 21 and extend along the second direction Y; The two ends of the auxiliary rod 23 are respectively fixedly connected to the two extension columns 222.

[0032] Furthermore, such as Figure 2 As shown, this is a specific example of the structural composition of the top frame 1; the top frame 1 includes longitudinal bars 11 and transverse bars 12; The two longitudinal bars 11 are spaced apart along the second direction Y and extend along the first direction X; the extension column 222 is connected to both ends of the longitudinal bars 11 in the first direction X. At least two of the crossbars 12 are spaced apart along a first direction X and extend along a second direction Y, and the crossbars 12 are detachably connected to the longitudinal bars 11; the lower surface of the crossbars 12 defines the training plane.

[0033] Furthermore, such as Figure 2 and Figure 4 As shown, to specifically realize the detachable connection between the crossbar 12 and the longitudinal bar 11; the top frame 1 also includes an adjusting member 13; The adjusting member 13 has a first connecting hole 131 and a second connecting hole 132; the first connecting hole 131 penetrates both sides of the adjusting member 13 in the first direction X; the second connecting hole 132 is spaced below the first connecting hole 131 and penetrates both sides of the adjusting member 13 in the second direction Y. The adjusting member 13 is detachably sleeved on the outer periphery of the longitudinal rod 11 through the first connecting hole 131, and detachably sleeved on the outer periphery of the transverse rod 12 through the second connecting hole 132.

[0034] The working process of this utility model is as follows: (1) When raising and lowering the top frame 1 as a whole The four motors are controlled to rotate synchronously. Driven by the motors, the end of the push rod away from the motor moves closer to or further away from the motor, thereby causing the extension column 222 to descend or rise relative to the support column 221. This causes the four corners of the top frame 1 to descend or rise synchronously, thus achieving the overall descent or rise of the top frame 1 and correspondingly descent or rise of the training plane.

[0035] (2) When raising or lowering one end of the top frame 1 in the first direction X The two motors located in the same lifting assembly 2 are controlled to rotate synchronously. Driven by the motors, the end of the push rod away from the motor moves closer to or further away from the motor, thereby causing the extension column 222 to descend or rise relative to the support column 221. This causes the two corners of the top frame 1 on the same side in the first direction to descend or rise synchronously, thereby achieving the descent or rise of one end of the top frame 1 in the first direction X, and adjusting the gripping point position on the training plane accordingly.

[0036] In summary, this utility model embodiment provides a height-adjustable rehabilitation frame 100 for a nursing bed, which includes a top frame 1 and a lifting assembly 2; the top frame 1 provides a training plane required for rehabilitation training; since one end of the extension column 222 is fixedly connected to the top frame 1 and the other end is slidably connected to the support column 221, the power end 2231 of the reciprocating mechanism 223 is fixedly connected to the extension column 222, the moving end 2232 is fixedly connected to the cross frame 21, and the bottom end of the support column 221 is fixedly mounted on the cross frame 21; such that when the power end 2231 drives the moving end 2232 to move up and down, the extension column 222 moves along the support column 221. Relative sliding occurs, thereby changing the height of the extension column 222 relative to the nursing bed, which in turn causes a change in the relative height between the top frame 1 connected to the extension column 222 and the bed surface of the nursing bed; and the two lifting units 22 are spaced apart on the cross frame 21 along the second direction Y. The two lifting units 22 at the same end in the first direction X use the cross frame 21 as a reference when lifting, which facilitates synchronous lifting. When the bed is adjusted to the Te's position or the reverse Te's position, one end of the top frame 1 is adjusted accordingly to adapt to the angle of the nursing bed; thus avoiding the need to disassemble and reassemble part of the rehabilitation frame structure, reducing labor costs and improving adjustment efficiency.

[0037] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
