Description

Technical Field

[0001] This utility model relates to the field of nursing technology, and in particular to a bedside rehabilitation chair. Background Technology

[0002] Patients who are bedridden for extended periods need regular rehabilitation training to prevent problems such as hypostatic pneumonia, thrombosis, muscle atrophy, and pressure sores caused by prolonged immobility. Among common rehabilitation exercises, bedside chair exercises, standing exercises, and stepping exercises are particularly suitable for frail patients. These exercises can help improve atelectasis, strengthen lower limb muscles to prevent muscle atrophy, and promote blood circulation to prevent thrombosis.

[0003] However, some patients are physically weak and require multiple people to assist them in moving them from bed to the ground. Furthermore, using ordinary chairs and braces for exercise only allows them to complete one exercise item: standing or sitting, and there are certain safety risks involved. Utility Model Content

[0004] This invention provides a bedside rehabilitation chair that improves the safety of training, reduces the difficulty of transferring patients to the ground, and saves manpower.

[0005] This utility model provides a bedside rehabilitation chair, including: a height-adjustable base;

[0006] The seat surface is installed on the top of the lifting base. The circumferential side of the seat surface includes a first contact surface, a concave side surface, a second contact surface, and an outer side surface that are connected end to end. The outer side surface is connected to a guard plate, which is used for the patient to hold on or lean against.

[0007] The lifting base can adjust the height of the seat surface to be flush with the support surface of the bed. The first contact surface and the second contact surface are located in the same vertical plane and are used to contact the side of the bed at the same time. The seat surface is constructed such that when the first contact surface and the second contact surface are in contact with the side of the bed at the same time, the concave side surface and the bed form an active hole that can be inserted into the lower body of the human body.

[0008] In one embodiment, the seat surface is symmetrical about a first straight line, which is perpendicular to the first contact surface.

[0009] In one embodiment, the concave side surface includes a first plane, a first arc surface, and a second plane connected in sequence; the outer side surface includes a third plane, a second arc surface, and a fourth plane connected in sequence.

[0010] Wherein, the center of the first arc surface coincides with the center of the second arc surface, and any two of the first plane, the second plane, the third plane and the fourth plane are parallel to each other.

[0011] In one embodiment, the first plane and the second plane are tangent to the opposite sides of the first arc surface, and the third plane and the fourth plane are tangent to the second arc surface.

[0012] In one embodiment, the protective plate is bent into a U-shape, and the end face of the first end of the protective plate is flush with the first mating surface, and the end face of the second end of the protective plate is flush with the second mating surface.

[0013] In one embodiment, handrails are provided at both the first and second ends of the guard plate.

[0014] In one embodiment, the lifting base includes a base plate and a first lifting mechanism and a second lifting mechanism mounted on the base plate. The vertical projection profile of the base plate is completely contained within the vertical projection profile of the seat surface. Both the first lifting mechanism and the second lifting mechanism are located outside the movable hole.

[0015] In one embodiment, the first lifting mechanism includes a scissor lift assembly and a drive cylinder. One end of the drive cylinder is rotatably connected to the base plate, and the other end is connected to a rod in the scissor lift assembly to drive the rod to rotate and extend or shorten the scissor lift assembly.

[0016] In one embodiment, the seat surface is also equipped with an infusion rod.

[0017] In one embodiment, the seat surface has a drain outlet, and a bedpan is installed at the bottom of the seat surface, with the top opening of the bedpan communicating with the drain outlet.

[0018] Compared with existing technologies, the advantages of this invention are that the height of the seat can be adjusted so that the seat surface is flush with the hospital bed, and the first and second contact surfaces of the seat are respectively aligned with the hospital bed, thus forming an access hole for the patient's legs to extend into. Because the seat surface is flush with the hospital bed, the patient can move their legs into the access hole and then gradually transfer to the seat surface by moving around, reducing the difficulty of transferring the patient and improving the safety during rehabilitation training.

[0019] Furthermore, because the chair and the hospital bed form an enclosing structure, after the patient extends their legs into the movement hole, they can stabilize their body not only by holding onto the hospital bed but also by holding onto the seat or backrest of the chair. This allows the patient to perform stepping exercises in place within the movement hole, improving their leg strength. If they feel uncomfortable, they can sit on the chair or the hospital bed to stop exercising, thus improving the safety of rehabilitation exercises. Attached Figure Description

[0044] The present invention will be further described below with reference to the accompanying drawings.

[0045] See Figures 1 to 3 As shown, this utility model provides a bedside rehabilitation chair, which includes:

[0046] The lifting base 100 and the seat 200 are mounted on top of the lifting base 100. The lifting base 100 can adjust the height of the seat 200 to be flush with the support surface of the bed.

[0047] See Figure 1 and Figure 4 As shown, the circumferential side surface of the seat surface 200 includes a first contact surface 210, a concave side surface 220, a second contact surface 230, and an outer side surface 240 connected end to end. A guard plate 300 is provided at the outer side surface 240. The first contact surface 210 and the second contact surface 230 are located in the same vertical plane and are used to simultaneously contact the side surface of the bed. The seat surface 200 is constructed such that when the first contact surface 210 and the second contact surface 230 are simultaneously contacted with the side surface of the bed, the concave side surface 220 and the bed form an opening through which the lower body of a person can be inserted.

[0048] When using the bedside rehabilitation chair provided in this embodiment, the height of the base 100 can be adjusted to be flush with the support surface of the bed using the lifting function of the base. Then, the bedside rehabilitation chair is moved so that the first contact surface 210 and the second contact surface 230, which are located in the same vertical plane, simultaneously contact the side of the bed. This causes the concave side surface 220 located between the first contact surface 210 and the second contact surface 230 to form a movable hole with the side of the bed.

[0049] When a patient needs to be transferred from a hospital bed to a bedside rehabilitation chair, they can first insert their legs into the movable holes, and then use their upper limbs to move their body onto the seat surface 200, which is flush with the bed support. Understandably, moving the body requires less strength than standing or walking, reducing the difficulty of transferring the patient from the bed. This allows even patients with weaker physical strength to complete the transfer independently, and also reduces the difficulty of retrieving bedding.

[0050] Furthermore, because the bedside rehabilitation chair and the hospital bed form an access hole, patients can not only use the hospital bed for support after extending their legs into the access hole, but also use the seat 200 and armrest 300 of the bedside rehabilitation chair for support. There are handholds regardless of which direction the patient is facing. When patients perform stepping exercises in place through the access hole, the seat 200 and the bed frame on all sides not only provide a greater sense of security, but also allow them to sit down at any time when they feel weak, reducing the risk of falls during rehabilitation exercises.

[0051] See Figure 1 and Figure 4 As shown, in some implementations, the seat surface 200 is symmetrical to the first straight line, and the first straight line is perpendicular to the first contact surface 210.

[0052] Because the seat surface 200 is an axisymmetric shape, and the first straight line of the axis of symmetry is perpendicular to the first contact surface 210 that is attached to the side of the bed, the area of ​​the first contact surface 210 of the seat surface 200 is equal to the area of ​​the second contact surface 230. The bearing area on both sides of the seat surface 200 is also equal. When the patient moves his / her body, it is relatively convenient to move from the first contact surface 210 to the seat surface 200 or from the second contact surface 230 to the base plate 110.

[0053] See Figure 1 and Figure 4 As shown, in some implementations, the concave side surface 220 includes a first plane 221, a first arc surface 222, and a second plane 223 connected in sequence; the outer side surface 240 includes a third plane 241, a second arc surface 242, and a fourth plane 243 connected in sequence; wherein the center of the first arc surface 222 coincides with the center of the second arc surface 242, and any two of the first plane 221, the second plane 223, the third plane 241, and the fourth plane 243 are parallel to each other.

[0054] Since the center of the first arc surface 222 coincides with the center of the second arc surface 242, the distance between the first arc surface 222 and the second arc surface 242 is equal to the difference in radii between the two arc surfaces. This ensures that the width of the seat surface 200 at the first arc surface 222 is uniform along the circumference of the first arc surface 222. As the patient moves along the circumference of the first arc surface 222, the width of the body-bearing area is more uniform, making movement smoother for the patient.

[0055] Similarly, since any two of the first plane 221, the second plane 223, the third plane 241 and the fourth plane 243 are parallel to each other, that is, the distance between the first plane 221 and the third plane 241 is a constant value, and the length between the second plane 223 and the fourth plane 243 is a constant value, the width of the seat surface 200 in the plane extension area is also relatively uniform.

[0056] See Figure 1 , Figure 4 and Figure 5 As shown, in some implementations, the first plane 221 and the second plane 223 are tangent to both sides of the first arc surface 222, while the third plane 241 and the fourth plane 243 are tangent to both sides of the second arc surface 242. Any two of the first plane 221, the second plane 223, the third plane 241, and the fourth plane 243 are parallel to each other. This causes the concave side surface 220 and the outer side surface 240 to form a racetrack structure. The distance between the first plane 221 and the third plane 241 is equal to the distance between the first arc surface 222 and the second arc surface 242. The width of the seat surface 200 remains essentially unchanged when the user moves from the first plane 221 to the first arc surface 222, making it smoother for the patient to move.

[0057] Furthermore, because the plane and the arc are tangentially connected, the transition between them is smoother, preventing scratches to the patient's clothing or skin due to poor connections between the surfaces.

[0058] Understandably, a leather cushion could be wrapped around the seat 200 to improve comfort. Of course, other soft materials, such as knitted cushions or sponge cushions, could also be used.

[0059] See Figure 1 , Figure 5 and Figure 6 As shown, in some implementations, the guard plate 300 is curved into a U-shape, such that the outer peripheral surface of the guard plate 300 is flush with the outer surface 240 of the seat surface 200, and the end face of the first end of the guard plate 300 is flush with the first contact surface 210, and the end face of the second end of the guard plate 300 is flush with the second contact surface 230. That is, in use, the two end faces of the guard plate, along with the first contact surface 210 and the second contact surface 230, directly contact the bed frame. When the patient sits on the seat surface 200, it provides proper protection, preventing the patient from falling off. The user can lean against the guard plate 300 while sitting on the seat surface 200, improving user comfort. Furthermore, the patient can also hold onto the guard plate 300 while performing stationary stepping exercises within the movement holes, enhancing safety.

[0060] Since the first end of the protective plate 300 extends to the intersection of the first mating surface 210 and the outer side surface 240, and the second end of the protective plate 300 extends to the intersection of the second mating surface 230 and the outer side surface 240, it can be seen that the extension length of the protective plate 300 is relatively long, providing protection for various parts of the outer side surface 240.

[0061] See Figure 8 As shown, in some implementations, the first and second ends of the guard plate 300 are equipped with handrails 400, which can be used by the patient to hold the handrails 400 when exercising in place, and can also provide traction for the patient by pulling the handrails 400 when the patient moves to the seat 200, making it convenient for the patient to move his / her body.

[0062] See Figure 1 , Figure 6 and Figure 7 As shown, in some implementations, the lifting base 100 includes a base plate 110 and a first lifting mechanism 120 and a second lifting mechanism 130 mounted on the base plate 110. The vertical projection of the base plate 110 is completely contained within the vertical projection of the seat surface 200. The first lifting mechanism 120 and the second lifting mechanism 130 are both located outside the movable hole.

[0063] The height of the seat surface 200 is controlled by the first lifting mechanism 120 and the second lifting mechanism 130, thereby achieving the lifting and adjustment of the seat surface 200. The vertical projection of the base plate 110 is completely contained within the vertical projection of the seat surface 200. Here, the vertical projection of the base plate 110 refers to the shadow obtained by a large area of ​​vertical light rays emanating from directly above the base plate 110, which can reflect the area and shape of the base plate 110 in the horizontal plane. Similarly, the vertical projection of the seat surface 200 is the shadow obtained by a large area of ​​vertical light rays emanating from directly above the seat surface 200, which can reflect the area and shape of the bottom surface in the horizontal plane.

[0064] Since the vertical projection of the base plate 110 is completely contained within the vertical projection of the seat surface 200, the base plate 110 does not extend beyond the vertical projection outline of the seat surface 200 in the horizontal direction. Furthermore, both the first lifting mechanism 120 and the second lifting mechanism 130 are located outside the movable hole, allowing the movable hole to penetrate the bedside rehabilitation chair in the vertical direction.

[0065] Because there is no obstruction at the bottom of the movable hole, patients can place their legs directly on the ground after inserting them into the hole. Compared to stepping on the base plate 110 for in-place exercises, this reduces damage to the base plate 110 and avoids falls caused by cracking the base plate 110. This improves the safety of patients when performing in-place exercises.

[0066] See Figure 1 , Figure 4 and Figure 6As shown, the first lifting mechanism 120 and the second lifting mechanism 130 are arranged at intervals along a second straight line, wherein the second straight line is perpendicular to the first straight line. This positions the first lifting mechanism 120 below the first contact surface 210, and the second lifting mechanism 130 below the second contact surface 230. By setting two spaced-apart lifting mechanisms, the seat surface 200 is supported, which increases the support force while avoiding a long cantilever structure in the base, thus improving the stability of the seat surface 200.

[0067] See Figure 1 As shown, in some implementations, the first lifting mechanism 120 includes a scissor lift assembly 121 and a drive cylinder 122. One end of the drive cylinder 122 is rotatably connected to the base plate 110, and the other end of the drive cylinder 122 is connected to a rod in the scissor lift assembly 121 to drive the rod to rotate and realize the extension or retraction of the scissor lift assembly 121.

[0068] The scissor lift assembly 121 is a common structure in lifting mechanisms, generally comprising at least two rotatably connected rods. As shown in the figure, the bottom end of rod A1211 is rotatably connected to the base plate 110, while the top end of rod A1211 is slidably mounted in a track below the seat surface 200. Similarly, the top end of rod B1212 is rotatably connected to the seat surface 200, while the bottom end of rod B1212 is slidably mounted in a track of the base plate 110, and the middle portions of rod A1211 and B1212 are rotatably connected. The sliding direction of the top end of rod A1211 is horizontal, and the sliding direction of the bottom end of rod B1212 is also horizontal.

[0069] When the drive cylinder 122 extends, the drive cylinder 122 and the rod A1211 rotatably connected to the drive cylinder 122 rotate simultaneously. The rod A1211 rotates upward, raising the hinge point between the rod A1211 and the rod B1212, and driving the rod B1212 to rotate synchronously, thereby raising the seat surface 200.

[0070] When the drive cylinder 122 shortens, the drive cylinder 122 and the rod A1211 rotatably connected to the drive cylinder 122 rotate simultaneously. The rod A1211 rotates downward, which lowers the hinge point between the rod A1211 and the rod B1212, causing the drive rod B1212 to rotate synchronously, thereby lowering the seat surface 200.

[0071] Figure 1 In this design, the rotating end (bottom end) of rod A1211 is close to the first contact surface 210 of the seat surface 200, while the sliding end of rod A1211 is away from the first contact surface 210 of the seat surface 200. During the sliding process of rod A1211 along the slide rail, the sliding end of rod A1211 will not extend beyond the first contact surface 210. This avoids lifting and lowering jams caused by the sliding end contacting the bed body during the lifting and lowering process.

[0072] See Figure 1 As shown, the scissor lift assembly 121 includes two pairs of cross rods, each pair of cross rods including a rod body A1211 and a rod body B1212. The rod bodies A1211 of the two pairs of cross rods are connected by a horizontal connecting rod 123, and the drive cylinder 122 is rotatably connected to the horizontal connecting rod 123, thereby realizing the rotatable connection between the drive rod and the rod body A1211.

[0073] The second lifting mechanism 130 is the same as the first lifting mechanism 120, and the first lifting mechanism 120 and the second lifting mechanism 130 are symmetrical along a first straight line. This ensures stable support on both sides of the bedside rehabilitation chair and prevents unevenness in the bedside rehabilitation chair.

[0074] See Figures 1 to 3 As shown, in some implementations, at least three casters 700 are installed at the bottom of the base plate 110 to facilitate the movement of the bedside rehabilitation chair. It is understood that a locking mechanism for locking the casters 700 is also installed at the bottom of the base plate 110. When the bedside rehabilitation chair moves to the target position, the locking mechanism locks the casters 700 to prevent the bedside rehabilitation chair from moving, thus improving its stability. The structure of the locking casters 700 varies, and will not be described in detail here; any structure that can lock the casters 700 is sufficient.

[0075] Although the above description uses a structure with a scissor lift assembly 121 to describe the lifting base 100, there are many structures for lifting the seat 200, and it is not necessarily the lifting base 100 with the scissor lift assembly 121. In other implementations, a hydraulic cylinder can also be used to directly adjust the lifting of the seat 200.

[0076] In some implementations, the bedside rehabilitation chair also includes a control device that can control the height adjustment of the lifting base 100 to accommodate beds of different heights. The control device can be located on the base plate 110, allowing the patient to adjust the height of the lifting base 100 by stepping on it. Alternatively, the control device can be located at the seat surface 200 or the backrest 300, allowing the patient to manually control the height of the lifting base 100.

[0077] See Figure 1 and Figure 7 As shown, in some implementations, the seat 200 is also equipped with an infusion pole 500. That is, when the patient is transferred to the bedside rehabilitation chair to rest, the infusion bottle can be hung on the infusion pole 500 to continue the infusion. This does not affect the accuracy of the treatment. Of course, when the patient is performing rehabilitation exercises in the movable opening, the infusion bottle can also be hung on the hook of the infusion pole 500 to continue the infusion.

[0078] It is understandable that the infusion pole 500 can be a telescopic pole. When the patient removes the infusion bottle from the bedside, the infusion pole 500 can be controlled to retract vertically, thereby lowering the height of the hook on the infusion pole 500. This allows the patient to easily hang the infusion bottle on the hook of the infusion pole 500, reducing the difficulty of transferring the infusion bottle.

[0079] See Figure 1 , Figure 2 and Figure 8 As shown, in some implementations, the seat 200 has a drain outlet 250, and a bedpan 600 is installed at the bottom of the seat 200. The top opening of the bedpan 600 is connected to the drain outlet 250. That is to say, the patient can also defecate in the bedside rehabilitation chair when needed. In particular, the top opening of the bedpan 600 is larger than the drain outlet 250 of the seat 200, so that the excrement falling from the drain outlet 250 can be directly guided into the bedpan 600, avoiding the excrement from falling on the base plate 110 and contaminating the bedside rehabilitation chair.

[0080] In some implementations, the bedpan 600 is detachably mounted on the seat 200. After the patient finishes urinating, the bedpan 600 can be removed from the bottom of the seat 200, making it convenient for caregivers to clean the bedpan 600.

[0081] In some implementations, a slide rail is provided at the bottom of the seat 200, and several hooks 800 are slidably connected in the slide rail. Figure 8 As shown in the figure, the patient's daily-use items can be hung on the hooks 800 at the bottom of the seat 200, and the position of the hanging items can be adjusted by sliding the hooks 800 along the slide.

[0082] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
