Description

A multifunctional rear seat walker

technical field

The invention belongs to the technical field of medical devices, and in particular relates to a multifunctional rear seat walker.

Background technique

The orthopaedic ward often treats patients with knee joint diseases such as osteoarthritis, rheumatoid arthritis, and hemophilic osteoarthritis. Within 3-4 days after the patient's knee replacement, the patient's early postoperative knee flexion can reach more than 90° and the muscle strength can reach grade 5. According to the doctor's advice, the patient can get out of bed and walk with a walker accompanied by family members or medical staff. walking exercise. At the same time, there are also many elderly people who are unable to walk on their own due to physical reasons. Therefore, walkers have become a necessary aid for orthopedic patients and many elderly people.

Clinically, the commonly used walker is a triangular metal frame made of aluminum alloy material, which is generally placed in front of the person being assisted to protect the front and left and right sides of the patient, and protect the patient in it. The person being assisted adopts the forward walking aid method, that is, after the person being assisted moves the walker forward for a certain distance with his hand, he moves his lower limbs and also tends to walk forward. The weight of the existing aluminum alloy walker is very light, and it is convenient for the patient to move by himself.

However, the existing walkers have the following problems in the use process: (1) For patients after knee replacement, their joint activities can basically reach a normal level. Generally, the metal frame in front of the walker limits the patient's mobility. The range of motion of the knee joint affects the effect of functional exercise to a certain extent; (2) After knee replacement, if the patient's endurance has not fully recovered, and the patient cannot walk too far or for too long, there are risk factors for falls; (3) ) Due to the patient's inability to exercise after the operation, when using a traditional walker, the patient has to sit down and rest immediately after walking for a period of time, which increases the workload of family members and nursing staff.

Therefore, the existing traditional walkers are difficult to ensure the purpose of the patient getting out of bed for walking exercise, and there are certain safety hazards. More importantly, the seat height of the existing general walker is fixed. Since the patient after knee or hip replacement requires a higher seat height when sitting, the existing general seat height is Fixed walkers are difficult to meet the needs of the elderly in the orthopaedic ward and postoperative patients at the same time.

SUMMARY OF THE INVENTION

Therefore, the technical problem to be solved by the present invention is to provide a multifunctional rear seat walker to solve the problem that the traditional walker in the prior art is not conducive to patient exercise and safety.

In order to solve the above technical problems, the multifunctional rear seat walker of the present invention includes a support frame assembly and a seat movably fixed to the rear side of the support frame assembly in the traveling direction.

Preferably, the multifunctional rear seat walker further comprises a roller disposed below the support frame assembly.

The support frame assembly is a triangular metal frame, including an armrest support assembly and a backrest support assembly placed on both sides of the patient's body, and the seat is arranged inside the frame of the support frame assembly.

A screw drive assembly is fixedly connected to the bottom of the seat to control the lifting and lowering of the seat.

The support frame assembly is an assembled structure composed of longitudinal support rods and transverse support rods, the longitudinal support rods and the transverse support rods are connected and fixed by pipe joints, and selectively fixed by fasteners.

The length of the armrest support assembly is 80-85cm, the distance is 48-52cm, and the height is 78-82cm.

The length of the seat is 25-30 cm, the width is 50-52 cm, the thickness is 3-5 cm, and the height from the ground is 50-55 cm.

The height of the back support assembly is 90-100 cm, and the top end portion extends to the outside of the frame of the support frame assembly.

The walker also includes a handbrake assembly disposed at the position of the roller.

The armrest support assembly is also provided with a hook, an LED light and/or a water cup fixing ring, and a folding small table board with one end fixed to the armrest support assembly.

The rear seat walker of the utility model is made of triangular stainless steel material, which can protect the patient in it, and the walker is additionally provided with a seat, which can be convenient for the patient to rest when they are not physically fit. The walker adopts a rear seat structure, and the joint activities of patients after knee joint replacement can basically reach a normal level, and the metal frame at the back will not limit the patients' knee joint activities, and achieve the purpose of functional exercise. . The walker can be made by splicing a lateral support rod and a longitudinal support rod, and on the premise of ensuring the stability of the structure, the modular production of the walker can be realized.

The walker of the present invention can control the lift of the seat by itself by arranging a screw drive assembly at the bottom of the seat and using the characteristics of the existing well-known screw drive assembly, so that the walker can automatically control the lifting of the seat. The height of the seat can be adjusted, which can not only meet the use of the general elderly, but also can be adjusted to meet the needs of patients with orthopaedic joint surgery.

When the chair 2 is lifted according to the needs of the patient, the patient only needs to shake the crank handle 103 to drive the lift handle 104 to rotate, so that the lift screw 105 rotates for transmission, and the lift screw 105 rotates to drive the slide connected to the lift screw 105. The block 110 moves and pushes the connecting rod 106 to move. The connecting rod 106 slides between the upper chute rod 101 and the lower chute rod 102. Under the connection of the connecting sheath 107, the connection The rod 106 drives the seat 2 to rise. Conversely, when the height of the seat 2 needs to be lowered, the crank handle 103 can be reversely shaken.

As a preferred structure, the armrest support assemblies 4 and 5 can also be provided with hooks, LED lights and/or water cup fixing rings at any positions as required, so as to realize multi-functional use by patients; The metal frame can also be provided with a folding small table board, one end of the folding small table board is fixed on the armrest support components 4 and 5, and can be folded and stored.

The use process of the rear seat walker provided by the above embodiment is as follows:

The patient is in a sitting position after surgery, and the front end of the walker is placed on both sides of the patient's body. The patient's hands support the armrest support components 4 and 5 of the walker to stand up. After the patient walks forward to a wide area, he can turn back and continue to walk. . During the whole walking process, if the patient is physically weak or needs to adjust his pace, he can sit down and rest. When a patient is finished using, the nursing staff can sterilize the walker body and seat parts for the next use.

Obviously, the above-mentioned embodiments are only examples for clear description, and are not intended to limit the implementation manner. For those of ordinary skill in the art, changes or modifications in other different forms can also be made on the basis of the above description. There is no need and cannot be exhaustive of all implementations here. And the obvious changes or changes derived from this are still within the protection scope of the present invention.
