Abstract
Description
Technical Field
[0001] This utility model relates to the field of nursing chair technology, specifically to a nursing chair that assists in rehabilitation training. Background Technology
[0002] To make it easier for patients to get up, nursing chairs are equipped with handrails on the front side for patients to hold onto.
[0003] For example, in 202323103080.7, a multi-functional transfer chair is described. The caregiver rotates the handrail and drives the end with the support rod to rotate downwards. The patient or elderly person leans forward on the protective pad, then raises their hands and grips the handles. At the same time, the support rod is placed under the patient or elderly person's armpits and under their arms. Then, the caregiver operates the handrail again to make the end with the protective pad tilt upwards. At this time, the patient or elderly person is lifted up.
[0004] In the above solution, the protective pad and the support rod are fixed together on the L-shaped handrail. In reality, when the patient is helped up, the chest will shift relative to the protective pad, resulting in insufficient support stability. At the same time, the vertical setting of the handle is also inconvenient to hold. Utility Model Content
[0005] (I) Technical Issues
[0006] The present invention aims to at least solve the problem in the prior art that the protective pad cannot change position on the L-shaped handrail as the patient's chest cavity moves.
[0007] (II) Technical Content
[0008] This solution provides a nursing chair to assist in rehabilitation training, achieved through the following specific technical means, including:
[0009] The U-shaped base frame has an opening facing backwards, and swivel wheels are installed at all four corners of the bottom of the U-shaped base frame;
[0010] The lifting frame is fixed at its bottom to the front side of the U-shaped base frame;
[0011] The hinged seat is located at the rear of the lifting frame and consists of two sets of half-chairs. The two sets of half-chairs are symmetrically hinged to the left and right sides of the upper part of the lifting frame. When the two sets of half-chairs are close together, they combine to form a complete seat. When the two sets of half-chairs are far apart, it is convenient for patients to enter and exit.
[0012] The lifting mechanism includes an L-shaped handrail that is rotatably mounted on the top of the lifting frame at the rear end, and an inverted U-shaped handrail is welded to the upper side of the front end of the L-shaped handrail;
[0013] Meanwhile, armpit support rods are rotatably installed on both the left and right sides of the rear of the L-shaped handrail, and a chest support pad is movably connected to the middle of the rear of the L-shaped handrail.
[0014] Preferred technical solution 1: An L-shaped rear frame is rotatably installed in the middle of the L-shaped handrail, the free end of the L-shaped rear frame extends backward, and the chest support pad is fixed to the rear of the L-shaped rear frame; a support is fixed in the middle of the L-shaped handrail, the front end of the L-shaped rear frame is hinged to the support, and a limit plate is fixed on the rear wall of the support to limit the rear rotation angle of the L-shaped rear frame.
[0015] Preferred technical solution 2: A leg guard is fixedly installed in the middle of the lifting frame, located in front of the seat, to protect the patient's legs from the front. A hand-cranked screw lift is connected between the front end of the L-shaped handrail and the leg guard.
[0016] Preferred technical solution 3: The lifting frame includes uprights fixed to the left and right sides of the front side of the U-shaped base frame, movable rods slidably sleeved on the uprights, and reinforcing rods fixedly connected between the top ends of the two sets of movable rods; the leg guards are welded between the lower middle parts of the two sets of movable rods.
[0017] Meanwhile, the rear end of the L-shaped handrail is rotatably mounted on the reinforcing rod.
[0018] Preferred technical solution four: The chair board of the half chair has a half hole. When the chair boards of the two sets of half chairs are close to each other, the two sets of half holes form a complete hole, which facilitates patients with mobility impairments to use the toilet.
[0019] Preferred technical solution five: a safety strap connects the backrests of the two sets of half chairs; at the same time, the vertical sections of the rear sides of the two sets of half chairs that are close to each other are also connected by a mechanical lock.
[0020] (III) Technical Effects
[0021] The above structure gives this solution the following advantages:
[0022] 1. The method of directly fixing the chest support pad to the L-shaped handrail has been changed to a hinged connection, allowing the chest support pad to rotate on the L-shaped handrail. This adapts to the relative position changes between the chest and the L-shaped handrail during the patient's ascent. As the patient rises, the chest cavity gradually changes from a position close to the back of the L-shaped handrail to a position away from the L-shaped handrail. At this time, the L-shaped back frame rotates accordingly, which can gradually raise the height of the chest support pad and lift the chest cavity forward during the raising process, maintaining a good fit and support effect on the chest cavity.
[0023] 2. Compared to lockable gas springs, this solution uses a hand-cranked screw hoist, which has better load-bearing capacity, is less prone to slippage, and is safer and more reliable;
[0024] 3. The inverted U-shaped handrails provide patients with a more comfortable and diverse way to grip. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0032] Example 1
[0033] Please see Figures 1-4 The nursing chair that assists in rehabilitation training includes a U-shaped base frame 1, a lifting frame 2, a hinged seat 3, and a standing mechanism 4, wherein:
[0034] The U-shaped base frame 1 has an opening facing backward, and casters 11 are installed at the four corners of the bottom of the U-shaped base frame 1. It is best to use casters with braking function. The bottom of the lifting frame 2 is fixed to the front side of the U-shaped base frame 1, and the height of the middle and upper part can be adjusted. The opening and closing seat 3 is located on the rear side of the lifting frame 2 and consists of two sets of half chairs. The two sets of half chairs are symmetrically hinged to the left and right sides of the middle and upper part of the lifting frame 2. When the two sets of half chairs are close together, they are combined to form a complete seat. When the two sets of half chairs are far apart, it is convenient for patients to enter and exit.
[0035] The lifting mechanism 4 includes an L-shaped handrail 41 that is rotatably mounted on the top of the lifting frame 2 at the rear end. An inverted U-shaped handrail 42 is welded to the upper front end of the L-shaped handrail 41. The inverted U-shaped handrail 42 has vertical grip sections on the left and right sides and a horizontal grip section in the middle, providing multiple grip positions.
[0036] Meanwhile, axillary support rods 43 are rotatably installed on both the left and right sides of the rear of the L-shaped handrail 41, and a chest support pad 45 is also movably connected to the L-shaped handrail 41. The axillary support rods 43 can rotate towards the middle of the rear of the L-shaped handrail 41 to get closer to the patient, or they can rotate outward away from the patient. When in use, the patient holds the inverted U-shaped handrail 42, the axillary support rods 43 are located under the armpits, and the chest is against the chest support pad 45. As the L-shaped handrail 41 rotates forward and downward, the axillary support rods 43 lift the patient up. At this time, due to the movable connection between the chest support pad 45 and the L-shaped handrail 41, when the person stands up, the chest support pad 45 can move with the chest when the chest moves relative to the L-shaped handrail 41.
[0037] A leg guard 5 is fixedly installed on the front side of the middle part of the lifting frame 2 to protect the patient's legs from the front.
[0038] A hand-cranked screw lift 6 is connected between the front end of the L-shaped handrail 41 and the leg guard 5. The bottom end of the hand-cranked screw lift 6 is hinged to the leg guard 5, and the top lifting end of the hand-cranked screw lift 6 is hinged to the front end of the L-shaped handrail 41. This provides better load-bearing capacity, makes it less prone to slipping, and is safer and more reliable.
[0039] When it is necessary to lift the patient, the overall length of the hand-cranked screw lift 6 is extended by cranking the handle on the hand-cranked screw lift 6, so that the front end of the L-shaped handrail 41 can be lifted upward, that is, the rear end can be lifted downward and moved closer to the patient.
[0040] When not in use, cranking the handle on the hand-cranked screw lift 6 will shorten the overall length of the screw lift 6, causing the front end of the L-shaped handrail 41 to move downwards, that is, the rear end to tilt upwards and move away from the patient.
[0041] Example 2
[0042] Based on Example 1
[0043] Please see Figures 1-4 The nursing chair that assists in rehabilitation training has a support 411 fixed in the middle of the L-shaped handrail 41. An L-shaped rear frame 44 is rotatably mounted on the support 411. The free end of the L-shaped rear frame 44 extends backward, and the chest support pad 45 is fixed to the rear of the L-shaped rear frame 44. A limit plate 412 is fixed on the rear wall of the support 411 to limit the rear rotation angle of the L-shaped rear frame 44.
[0044] In use, when the L-shaped rear frame 44 is rotated backward, causing the chest support pad 45 to move backward between the two sets of armpit support rods 43, the rear wall of the L-shaped rear frame 44 contacts the limiting plate 412, preventing the L-shaped rear frame 44 from rotating further backward. This also positions the two sets of closely spaced armpit support rods 43 close to the left and right sides of the chest support pad 45. Figure 2 As shown, the patient leans forward, holding onto the inverted U-shaped handrails 4234, with their chest resting against the chest support pad 45. Simultaneously, their upper arms are supported by two sets of axillary support bars 43. The patient can pull themselves up using their own arms, or another person can assist by rotating the L-shaped handrails 41 forward and downward. The axillary support bars 43 then support the patient. During the ascent, the patient's chest gradually changes from being close to the back of the L-shaped handrails 41 to being away from them. At this time, the L-shaped rear support 44 rotates accordingly, gradually raising the height of the chest support pad 45 and lifting the chest forward during this process, maintaining a good fit and support effect.
[0045] Example 2
[0046] Based on Example 2
[0047] Please see Figure 1 and Figure 3 The nursing chair that assists in rehabilitation training includes a lifting frame 2 consisting of uprights 21 fixed to the left and right sides of the front of the U-shaped base frame 1, movable rods 22 slidably sleeved on the uprights 21, and reinforcing rods 23 fixedly connected between the tops of the two sets of movable rods 22. L-shaped handrails 41 are rotatably mounted on the reinforcing rods 23.
[0048] A manual jack 24 is located between the middle of the U-shaped base frame 1 and the reinforcing rod 23. The bottom end of the manual jack 24 is fixed to the middle of the U-shaped base frame 1, and the top telescopic end is fixed to the reinforcing rod 23. Alternatively, the manual jack 24 can be replaced with an electric push rod. The bottom end of the electric push rod is fixed to the middle of the U-shaped base frame 1, and the top telescopic end is fixed to the reinforcing rod 23. The overall height of the lifting frame 2 is adjusted by extending and retracting the electric push rod. The specific model of the electric push rod, as well as its matching power supply and control switch, can be provided by the manufacturer. The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art and need not be elaborated upon.
[0049] The leg guard 5 is welded between the lower part of the two sets of movable rods 22; at the same time, the rear end of the L-shaped handrail 41 is rotatably mounted on the reinforcing rod 23.
[0050] The half-chair includes a frame 31 hinged to the movable rod 22, a chair board 32 fixed at the bottom of the frame 31, a backrest 33 fixed at the rear of the frame 31, and a push handle 34 provided on the backrest 33 for easy gripping and pushing from the rear.

The right front end of the frame 31 on the right side is hinged to a set of movable rods 22 on the right side by a stainless steel hinge, and an armrest is also fixed to the right side of this set of frame 31.
[0051] Half-holes are provided in the middle of the near side of the two sets of chair boards 32. When the two sets of chair boards 32 are close to each other, the two sets of half-holes form a complete hole. When the patient sits on the chair board 32, the nursing chair is moved to the toilet. At this time, the U-shaped base frame 1 surrounds the outside of the toilet, and the hole is directly facing the toilet opening below, which makes it convenient for patients with mobility difficulties to use the toilet. After use, the patient is moved back to the bed. After the patient is helped up, the two sets of half chairs are separated to the left and right. At this time, the patient can move out between the two sets of half chairs and the U-shaped base frame 1.
[0052] Safety straps 35 connect the two sets of backrests 33. It is best to choose safety straps 35 with matching buckles at the ends. At the same time, the vertical sections of the rear end of the frame 31 that are close to each other are also connected by a mechanical lock 36. The mechanical lock 36 can be a U-lock. The mechanical lock 36 and the safety straps 35 provide double safety protection.
[0053] A bullhorn-shaped handle 7 is also fixedly installed on the front side of the reinforcing rod 23, making it more powerful to push;
[0054] A cushioning pad 8 is installed and fixed on the rear wall of the middle part of the U-shaped base frame 1 to prevent the middle part of the U-shaped base frame 1 from directly impacting the toilet when it is moved to the toilet.
[0055] The parts not disclosed in this utility model are all prior art, and their specific structures and working principles will not be described in detail.
[0056] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
