Description

Technical Field

[0001] The utility model relates to the technical field of rehabilitation equipment, in particular to a cushion for assisting patients with spinal cord injuries in putting on and taking off their pants. Background Art

[0002] Spinal cord injury is the most serious complication of spinal cord injury, often leading to severe functional impairment of the limbs below the injured segment, and in severe cases, quadriplegia. Such patients not only face enormous physical challenges, but also have to overcome various inconveniences in daily life. Among them, the seemingly simple daily activity of dressing and taking off pants by themselves becomes a huge problem for them.

[0003] Putting on and taking off pants is a basic skill in daily life, crucial for maintaining personal hygiene, dignity, and social activities. However, for patients with spinal cord injuries, due to limited physical function, they often find it difficult to complete this action independently, which not only affects their quality of life but also brings them great psychological pressure.

[0004] Although advancements in medical technology have led to progress in the treatment and rehabilitation of spinal cord injuries, there is still a lack of effective solutions and targeted rehabilitation training equipment to help patients put on and take off their pants better. Traditional assistance methods often rely on the help of others, which not only increases the burden on caregivers but can also cause damage to the patient's self-esteem. In addition, due to long-term reliance on others for care, patients themselves are unable to receive effective rehabilitation training and find it difficult to actively promote recovery. Therefore, it is particularly important to develop an assistive device that can help patients with spinal cord injuries put on and take off their pants independently and conveniently and conduct targeted rehabilitation training. Utility Model Content

[0005] The utility model provides a cushion for assisting patients with spinal cord injuries in putting on and taking off pants, which is beneficial for helping patients to better independently perform targeted rehabilitation training in putting on and taking off pants.

[0006] The utility model is achieved in this way:

[0007] A cushion for assisting patients with spinal cord injury in putting on and taking off pants comprises a base, a first cushion and a second cushion being arranged on the top of the base and distributed on the left and right, an independent lifting mechanism being respectively arranged between the bottom of the first cushion and the second cushion and the base, the lifting mechanism comprising a lifting drive device and a lifting platform fixedly mounted on the base, the first cushion and the second cushion base being respectively fixedly connected to the lifting platform, the lifting drive device being able to control the lifting platform to drive the first cushion or the second cushion to perform lifting activities, independent pressure sensors being arranged inside the first cushion and the second cushion, a power supply device being also arranged on the base, and the power supply device, the pressure sensor and the lifting mechanism being electrically connected via a controller arranged on the base.

[0008] On the basis of the above technical solution, the lifting platform is a scissors-type lifting platform.

[0009] Based on the above technical solution, the first cushion includes a wrapping layer, an elastic filling layer and a supporting layer.

[0010] Based on the above technical solution, the second seat cushion has the same structure as the first seat cushion.

[0011] On the basis of the above technical solution, the pressure sensor is located between the supporting layer and the elastic filling layer.

[0012] Based on the above technical solution, the supporting layer is a rigid structure.

[0013] Based on the above technical solution, the wrapping layer is a water-repellent structure.

[0014] On the basis of the above technical solution, a first connecting belt with extensibility is provided between the first seat cushion and the second seat cushion, and the left and right sides of the first connecting belt are connected to the tops of the adjacent sides of the first seat cushion and the second seat cushion.

[0015] On the basis of the above technical solution, a second connecting belt with extensibility is provided on the periphery of the bottom of the first cushion and the second cushion and on the base.

[0016] Compared with the prior art, the present invention has at least the following advantages:

[0017] The utility model provides a cushion for assisting patients with spinal cord injuries in putting on and taking off pants. The cushion height can be adjusted according to the patient's needs through an independently controlled lifting mechanism, which facilitates leg movements and effectively assists in the process of putting on and taking off pants. When in use, the patient sits in the middle of the cushion and shifts the center of gravity by moving the torso left and right. The pressure sensor on the side after the center of gravity shifts obtains a corresponding signal. The threshold height on that side is raised with the help of the lifting mechanism. After the pressure sense on the other side is lost, the threshold height is lowered with the help of the mechanism, so that the buttocks on that side are suspended, making it convenient to put on or take off pants. After the center of gravity shifts left and right many times, the patient with spinal cord injury can put on pants. The provision of the pressure sensor not only improves the safety of use, but also provides data support for subsequent training effect evaluation. The overall design takes into account both comfort and practicality, which helps to improve the self-care ability and quality of life of patients with spinal cord injury, thereby filling the market gap in existing rehabilitation training equipment for putting on and taking off pants for patients with spinal cord injury, and helping patients to carry out targeted rehabilitation training.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Combine Figure 1-4 This embodiment discloses a cushion for assisting patients with spinal cord injury in putting on and taking off pants. The cushion aims to help patients better train their independence in putting on and taking off pants through innovative structural design, thereby improving their quality of life.

[0029] The seat cushion specifically includes a rectangular base 1, the base 1 is provided with an inner cavity, and the inner cavity is located at the top of the base 1 to form an open structure, and the inner cavity is used to install other components.

[0030] A first seat cushion 2 and a second seat cushion 3 are provided on the top of the base 1 and are distributed on the left and right. The first seat cushion 2 and the second seat cushion 3 are movably connected to the base 1 and can be independently raised and lowered to form a supporting structure with different heights. The structure is used to unilaterally support the buttocks of patients with spinal cord injury, making it convenient for patients with spinal cord injury to be trained in putting on and taking off pants.

[0031] Specifically, independent lifting mechanisms are respectively provided between the bottom of the first seat cushion 2 and the second seat cushion 3 and the base 1. The lifting mechanisms include a lifting drive device 5 and a lifting platform fixed on the base 1. The bases 1 of the first seat cushion 2 and the second seat cushion 3 are respectively fixedly connected to the lifting platform. The lifting drive device 5 can control the lifting platform to drive the first seat cushion 2 or the second seat cushion 3 to perform lifting activities. Independent pressure sensors 9 are provided inside the first seat cushion 2 and the second seat cushion 3. A power supply device 8 (using a dry storage battery) is also provided on the base 1. The power supply device 8, the pressure sensor 9, and the lifting mechanism are electrically connected through a controller provided on the base 1 (a single-chip microcomputer is used in this embodiment, and a PLC controller, etc. can also be used in other embodiments).

[0032] In the specific implementation process, the controller can generate corresponding instructions according to the sensing signals of the two pressure sensors 9 to control the operation state of the lifting mechanism. For example, when the patient tilts the center of gravity to the left, the pressure sensor 9 on the left detects a pressure signal of a threshold intensity, and the controller controls the lifting mechanism on the left to rise, driving the first seat cushion 2 on the left to rise (such as Figure 1As shown), at this time, the second seat cushion 3 on the right side is located at a lower position relative to the first seat cushion 2, so that the patient's right buttocks is in a suspended state. The suspended height in this embodiment is 1 cm, which can be designed according to the corresponding parameters according to actual needs. The suspended side is convenient for patients to put on and take off their pants. After repeated shifts of the left and right center of gravity, patients with spinal cord injuries can put on or take off their pants. Through the above operations, patients can effectively carry out targeted training on putting on and taking off pants independently, which can improve the patient's participation in rehabilitation training. With the assistance of the seat cushion, the patient's buttocks and lower limbs can receive precise rehabilitation training. During this process, the patient constantly tries to control the buttocks and lower limbs, which can repeatedly stimulate the muscle groups and nervous system of the damaged parts in a targeted manner, thereby achieving the effect of rehabilitation training.

[0033] Combine Figure 2 and Figure 3 As shown, in this embodiment, the lifting platform is a scissor-type lifting platform 4. The bottom of the scissor-type lifting platform 4 is connected to the base 1, and the top is connected to the first cushion 2 or the second cushion 3. It should be noted that the scissor-type lifting platform 4 is provided with a plurality of connecting rods in the front and rear directions to increase the support for the cushions and the lifting stability. In this embodiment, the lifting drive device 5 adopts a driving structure of a motor and a screw rod. The screw rod is horizontally arranged on the left and right, and its matching movable nut is connected to the sliding side of the bottom of the scissor-type lifting platform 4. Then, the lifting drive device 5 controls the relative distance between the left and right ends of the bottom of the scissor-type lifting platform 4 to control the lifting movement of the top of the lifting platform.

[0034] In this embodiment, Figure 4 As shown, the first seat cushion 2 comprises a wrapping layer 21, an elastic filling layer 22, and a support layer 23. The wrapping layer 21, located at the top surface structure and in direct contact with the patient's limbs, is made of water-repellent materials such as nylon, plastic, and leather, providing waterproof protection for the internal structure. The elastic filling layer 22 is filled with PP cotton, which imparts a certain degree of elasticity to the seat cushion and enhances seating comfort. The support layer 23, located at the bottom, is made of a rigid structure such as wood to provide sufficient rigid support, enhancing the structural stability and load-bearing stability of the seat cushion.

[0035] It should be noted that the second seat cushion 3 has the same structure as the first seat cushion 2 , and the pressure sensor 9 is located between the supporting layer 23 and the elastic filling layer 22 .

[0036] To ensure a more coherent outer structure of the seat cushions and prevent skin injury or trouser pinching when the first and second seat cushions 2, 3 become misaligned, a first, stretchable connecting strap 6 is installed between the first and second seat cushions 2, 3. The left and right sides of the first connecting strap 6 connect to the tops of the adjacent sides of the first and second seat cushions 2, 3. Furthermore, a second, stretchable connecting strap 7 is installed around the bottom periphery of the first and second seat cushions 2, 3, and the base 1. The first and second connecting straps 6, 7 are made of elastic bands, which can wrap and seal the seam connecting the first and second seat cushions 2, 3 when the seats are in motion.

[0037] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
