Description

Technical Field

[0001] The present invention belongs to the technical field of nursing equipment and wheelchairs, and in particular relates to a multifunctional nursing wheelchair. Background Art

[0002] A significant number of patients have completely or substantially lost control of their lower limbs, requiring prolonged bed rest. The downside of prolonged bed rest is a lack of exercise for the lower limbs, leading to gradual muscle atrophy. Whether in a hospital or at home, the most challenging aspect of caring for bedridden patients is urination and defecation. Over time, caregivers and family members alike grow impatient and complain to doctors and others.

[0003] Therefore, the inventors have noticed that if patients can move their bodies independently with the help of wheelchairs, it will not only greatly reduce the work and psychological burden of nursing staff, but also, in the process of movement, it is actually a kind of exercise for their lower limb muscles. For example, in the hospital area, patients are often transferred to other departments (for laboratory tests, blood draws, etc.) or referred (for treatment of other patients in the hospital). Normal patients can go to the hospital on their own and move to the equipment seat (such as an oral treatment chair) for examination and operation. However, for patients with difficulty or obstacles in their own movements, the simple movement of moving from a wheelchair to a dental chair is completely impossible to achieve without the help of outsiders. This naturally requires the patient's family to accompany the patient to the hospital, which not only increases the burden on family members, but also affects the patient's own experience and self-esteem.

[0004] Currently, there are some transfer machine products, but they are basically expensive and have a single function, which is only to help patients move. The single function and high price make their popularity low. Based on this, the present invention hopes to improve the existing transfer machine structure so that it can also assist patients in exercising appropriately, forming a multifunctional nursing wheelchair. Summary of the Invention

[0005] Based on the above purpose, the present invention provides a multifunctional nursing wheelchair, with which patients can complete the displacement of their bodies by themselves, thereby completing urination and defecation independently. In addition, when a caregiver is not present, they can also get out of bed by themselves and use the nursing wheelchair to perform standing exercises or short-distance walking exercises.

[0006] The technical solution adopted by the present invention is as follows: a multifunctional nursing wheelchair, including a chassis moving assembly, a bracket assembly and a seat assembly. The seat assembly is installed on the chassis moving assembly through the bracket assembly, and the height of the seat assembly relative to the chassis moving assembly can be adjusted through the bracket assembly.

[0007] The seat assembly includes a seat frame, a first seat panel, and a second seat panel. The first seat panel and the second seat panel are rotatably mounted on one side of the seat frame. When the first seat panel and the second seat panel are assembled together, they form a seat panel. When separated, the first seat panel and the second seat panel can rotate horizontally away from each other by an amplitude of not less than 90 degrees. Specifically, the first seat panel and the second seat panel are both mounted on a rotating member, and the rotating member serves as a rotation axis for both. Locking screws are also mounted on the first and second seat panels. When the locking screws are turned inward, they abut against the surface of the rotating member, locking the rotational movement of the first and second seat panels. Loosening the locking screws releases the rotation lock.

[0008] The seat assembly also includes a connecting rod, an arc-shaped linkage rod and an auxiliary push cylinder. The connecting rod is vertically fixed on the side of the seat bracket, the upper end of the connecting rod is hingedly connected to one end of the auxiliary push cylinder, the lower end of the connecting rod is hingedly connected to the rod body of the arc-shaped linkage rod, the other end of the auxiliary push cylinder is hingedly connected to one end of the arc-shaped linkage rod, and the other end of the arc-shaped linkage rod is fixedly connected to the rotating part. When the auxiliary push cylinder is extended and retracted, the first seat plate and the second seat plate can be pushed to flip upward relative to the horizontal plane or restore to the seat plate that is spliced ​​into a horizontal state.

[0009] Specifically, the seat support includes a seat support body, which extends laterally on both sides of the seat support body to form side wing frames, and the connecting rod is fixed to the outer end of the side wing frame, or the connecting rod can also be a vertical rod integrally formed at the outer end of the side wing frame; a handle is provided at the upper end of the seat support body, and the patient can use the handle to help stabilize the body and use the hands to assist the body movement when sitting in the wheelchair, and a crotch support member extending horizontally toward the seat plate is also provided in the middle of the lower end of the seat support body, and the crotch support member is a long strip structure with a soft cushion on its upper surface. When the patient sits on the seat plate, the long strip crotch support member does not hinder the movement, and the patient can ride on the crotch support member with the help of the crotch to bear part of the body weight when the patient is in the walking assistance exercise state.

[0010] The bracket assembly includes a main bracket, a first support arm, a second support arm and a main push cylinder. The main bracket is fixedly supported on the chassis moving assembly. The upper end of the main bracket is hingedly connected to the first support arm and the second support arm side by side in an upper and lower distribution. The other ends of the first support arm and the second support arm that are not hinged to the main bracket are respectively hingedly connected to the seat assembly. Specifically, the other ends of the first support arm and the second support arm are hingedly connected to the seat bracket body in an upper and lower position; one end of the main push cylinder is hinged to the lower position of the main bracket, and the other end of the main push cylinder is hinged to the first support arm or the second support arm. The extension and retraction of the main push cylinder can push the first support arm and the second support arm to rotate synchronously around their hinge points with the main bracket, so as to drive the seat bracket body to move up or down.

[0011] Preferably, the main bracket extends horizontally toward the side away from the seat assembly to form a first side bracket and a second side bracket, the main structures of the first support arm and the second support arm are both U-shaped, the end of the first side bracket is hinged to the U-shaped opening of the first support arm, and the end of the second side bracket is hinged to the U-shaped opening of the second support arm, so that the main bracket and the main push cylinder both pass through the U-shaped space of the first support arm and the second support arm.

[0012] The chassis moving assembly includes a chassis frame, and a wheel is respectively provided at the four corners of the chassis frame. The main bracket of the bracket assembly is nested and fixedly connected to the column on the chassis frame. For example, the main bracket is inserted into the interior of the column and then locked by a pin, or the column is inserted into the interior of the main bracket and then locked by a pin. At the same time, locking pin holes at multiple positions can be opened on the main bracket and the column, so that the initial height position of the main bracket installed on the chassis frame can be adjusted by plugging and pulling up and down. In addition, a footrest is installed on the chassis frame to support the patient's feet in a sitting state. Specifically, a mounting portion of the footrest is extended from the chassis frame, and a hinge seat is provided on the mounting portion. The bottom surface of the footrest is provided with a hinge portion, and the hinge seat and the hinge portion are hinged together by a pin shaft, and the height of the hinge seat is greater than the height of the hinge portion, so that the footrest has a forward and backward swinging range after being hingedly installed on the hinge seat. To avoid an excessive swinging range, the front and rear ends of the bottom of the hinge portion of the footrest respectively constitute a fulcrum. When the footrest is in a horizontal state, the fulcrum has a gap of 0.5cm-2cm from the chassis frame. After the footrest swings forward or backward to a certain range, the fulcrum touches the chassis frame to support and limit the continued swinging of the footrest, thereby increasing the comfort of the foot when placed on the footrest.

[0013] The nursing wheelchair of the present invention has the function of helping patients to move by relying on the seat to separate and close, and the function of assisting patients to stand and walk. When helping patients to move, the wheelchair is placed close to the bedside, one of the seat panels is swung sideways to the bed surface, the patient slightly lifts his buttocks and moves to the seat panel, and then the seat panel is moved to its original position to transfer the patient to the wheelchair. Alternatively, the patient sits at the bedside, the two seat panels of the wheelchair are separated outward, the wheelchair is moved until the chassis assembly of the wheelchair extends into the bottom of the bed, and then the two seat panels are folded inward. During the folding process, the seat panels are swung to the bed surface and moved under the patient's buttocks. When the two seat panels are closed, the patient is actually sitting on the seat assembly, and the wheelchair is moved to take the patient away from the bed surface.

[0014] When assisting standing or walking exercises, the support assembly and the seat assembly are coordinated for adjustment. After the patient has sat in the wheelchair, if he wants to perform a short period of standing exercise or a short-distance walking exercise, the patient first holds the handles with his hands, steps on the pedals with both feet or directly on the ground, and is in a standing state. The main push cylinder of the support assembly is adjusted so that the height of the crotch support adapts to the height of the patient's crotch, that is, the patient sits on the crotch support, and then the action of the secondary push cylinder is adjusted. The first seat plate and the second seat plate are flipped upwards until the first seat plate and the second seat plate are attached and supported on the patient's back, forming support and protection for the patient's standing posture through the two positions of the crotch and the back.

[0015] The multifunctional nursing wheelchair of the present invention has the following technical advantages:

[0016] 1. It is multifunctional and can not only help patients complete body shifting movements independently, but also the deformation of the seat components can provide back support and protection. By limiting the back and crotch, it helps patients maintain a safe standing or walking state.

[0017] 2. Two fulcrums are set at the lower end of the pedal, so that it has a certain range of forward and backward swing amplitude. When actually using the pedal, the forward and backward inclination angle of the pedal can be adjusted according to the physical condition. In addition, the swinging pair of the pedal can help patients exercise their ankle muscles, making the use experience more comfortable.

[0018] 3. Compared with the existing transfer machine structure, the main frame is basically similar, so the production cost will not increase, but the functions are increased, which improves the overall cost performance and is beneficial to increasing the popularity.

Figure 8 This is a schematic diagram of the footrest structure of the multifunctional nursing wheelchair of the present invention. As shown in the figure, the bottom of the footrest 1-3 has a hinge portion hingedly matched with the hinge seat 1-5, and the front and rear ends of the bottom of the hinge portion respectively form a fulcrum 1-3-1. The pin connection height supported by the hinge seat 1-5 is such that the bottom surface of the hinge portion of the footrest 1-3 is at a certain distance from the chassis frame 1-1, for example, a distance gap of 0.5cm-2cm is preferably left, so that the footrest 1-3 has a forward and backward swing amplitude, thereby increasing the comfort of the foot when placed on the footrest 1-3.

[0047] The multifunctional nursing wheelchair of the present invention has three action adjustment ranges: height adjustment, seat plate separation and closing, and assisted walking state. During height adjustment, the height of the seat assembly 3 can be adjusted through the bracket assembly 2, and the U-shaped main structure of the first support arm 2-2 and the second support arm 2-3, the main bracket 2-1 and the main push cylinder 2-4 are all interspersed in the U-shaped inner space. When the main push cylinder 2-4 pushes the seat assembly 3 up and down, the front and rear displacement distance of the seat assembly 3 is very small, which can relatively ensure that the seat assembly 3 has a large up and down lifting range and a small front and back swing range, providing a relatively stable sitting position.

[0048] When adjusting the seat plate, you can Figure 3 As shown, the wheelchair is placed close to the bedside, one of the seat panels is swung sideways to the bed surface, the patient lifts his buttocks slightly and moves onto the seat panel, and then the seat panel is moved back to its original position to transfer the patient to the wheelchair. Alternatively, the patient sits at the bedside, the two seat panels of the wheelchair are separated outward, the wheelchair is moved until the chassis assembly of the wheelchair extends under the bed, and then the two seat panels are folded inward. During the folding process, the seat panels are swung to the bed surface and moved under the patient's buttocks. When the two seat panels are closed, the patient is actually sitting on the seat assembly 3, and the wheelchair is moved to take the patient away from the bed surface.

[0049] In the assisting state, Figure 9The figure shows a schematic diagram of the walking-aiding state of the multifunctional nursing wheelchair of the present invention, which is coordinated by the support assembly 2 and the seat assembly 3. After the patient has sat in the wheelchair, if he wants to perform a short period of standing exercise or a short-distance walking exercise, the patient first holds the handle 3-1-3 with his hands, steps on the foot pedal 1-3 with both feet or steps directly on the ground, and is in a standing state. The main push cylinder 2-4 of the support assembly 2 is adjusted so that the height of the crotch support 3-1-4 adapts to the height of the patient's crotch, that is, the patient sits on the crotch support 3-1-4, and then adjusts the action of the auxiliary push cylinder 3-8. The first seat plate 3-2 and the second seat plate 3-3 are flipped upwards until the first seat plate 3-2 and the second seat plate 3-3 are attached and supported on the patient's back, so that the patient's standing posture is supported and protected by the two positions of the crotch and the back.

[0050] The battery is not shown in the figures of the present invention, but it should be obvious to those skilled in the art in combination with the prior art that the battery can be fixed on the chassis frame 1-1 or fixed on the main bracket 2-1 or the column 1-2, so that the main push cylinder 2-4 and the auxiliary push cylinder 3-8 are both electric push cylinders, so that the push cylinder movement is slow and controllable, and a motor can be installed on the chassis frame 1-1 to drive the four wheels 1-4 to move, so that the nursing wheelchair of the present invention has the function of an electric wheelchair. In addition, the main push cylinder 2-4 and the auxiliary push cylinder 3-8 can also be driven by pneumatic or hydraulic means. Of course, the main push cylinder 2-4 and the auxiliary push cylinder 3-8 can be completely replaced by a mechanical structure without external force, such as a structure in which a threaded rod and a threaded barrel are matched, that is, two sections of threaded rod are screwed into the two ends of the same threaded barrel. When the threaded barrel in the middle is screwed, the distance between the two sections of threaded rod is closer to or farther away from each other, thereby changing the length of the entire structure.

[0051] Although the above describes the specific embodiments of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that, based on the technical solution of the present invention, those skilled in the art can make modifications or deformations of various equivalent structures or equivalent processes without creative work, or directly or indirectly apply them to other related technical fields, which are still within the scope of protection of the present invention.
