Description

Technical Field

[0001] This utility model relates to the field of wheelchairs, and in particular to a wheelchair seat device that is easy to care for. Background Technology

[0002] For some patients who are bedridden for a long time or have limited mobility, wheelchairs are needed for mobility when going out. However, we have found that traditional wheelchairs mostly use a fixed seat design. When patients need to defecate, they often need to be transferred to the toilet or assisted by caregivers to get up and clean up, which is very inconvenient. Frequent transfers increase the patient's physical exertion and the risk of falls, which may cause secondary injuries, especially for patients with spinal cord injuries. Therefore, there is an urgent need for a wheelchair that does not require transfer and is easy to operate, so as to achieve a seamless connection between defecation care and daily use. Utility Model Content

[0003] The purpose of this invention is to provide a wheelchair seat device that is easy to care for, in order to solve the problems mentioned in the background art.

[0004] The technical problem solved by this utility model is achieved through the following technical solution:

[0005] A wheelchair-friendly seat device includes a first support and a second support, which are rotatably connected. Two seat portions are provided between the top crossbars of the first and second supports. Each seat portion has an open rotating portion, which is rotatably mounted on the first and second supports respectively. A limiting component is provided between each open rotating portion and the crossbar. The limiting component includes a protrusion on the open rotating portion, a sliding groove through which a limiting piece is slidably mounted. A limiting groove is provided on the crossbar, and the bottom end of the limiting piece can be embedded in the limiting groove.

[0006] Preferably, circular cavities are provided on both sides of the groove opening, and two guide posts are fixedly provided on the end cap of the limiting piece. The guide posts are slidably connected in the circular cavities, and an elastic reset component is connected between the lower end of the guide posts and the lower side wall of the circular cavity.

[0007] Preferably, each of the seat plates has a connecting portion on its rear end face, and a corrugated elastic band is fixedly connected between the two connecting portions.

[0008] Preferably, a front support is fixedly installed between the crossbar at the top of the first bracket and the second bracket.

[0009] Preferably, a seat cushion is fixedly installed on the upper surface of the seat plate, and the surface of the seat cushion is provided with an elliptical concave cavity.

[0010] Preferably, a crotch area is fixedly installed between the crossbar at the top of the first bracket and the second bracket.

[0011] The advantages and positive effects of this utility model are:

[0012] This invention employs a left-right opening and closing seat structure, with a linkage design between a limiting component and a corrugated elastic band, achieving controllable opening and closing angles and automatic reset functions. This avoids the cumbersome operation of transferring traditional wheelchairs to the toilet. The coordinated design of the front support and crotch area ensures stability during patient defecation while enhancing privacy and hygiene. The elastic cushioning effect of the corrugated elastic band limits the maximum opening to prevent discomfort from being suspended in the air and assists in quick closure and reset, significantly reducing the difficulty of operation for caregivers. The overall structure balances functionality, safety, and convenience, providing an efficient and comfortable nursing solution for patients with limited mobility and caregivers. The innovative and easy-to-care-for seat device allows for defecation without getting up, significantly improving the patient experience and nursing efficiency. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; they can refer to the internal communication of at least two components or the interaction relationship of at least two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances. The embodiments of this invention are further described in detail below with reference to the accompanying drawings:

[0023] Please see Figure 1-4 The present invention provides an embodiment of a wheelchair, comprising a wheel assembly 1 at the bottom, two leg exercise devices 2, a seat device 3 for easy care, and a foldable and adjustable backrest device 4. The foldable and adjustable backrest device 4 is mounted on the bracket of the wheel assembly 1, and the seat device 3 for easy care is mounted between the crossbars of the two leg exercise devices 2. When the patient sits on the seat device 3 for easy care, the seat is designed to open from the left and right, so it can be opened from the middle, allowing the patient to relieve themselves without getting up, simply by opening the bottom seat. This also facilitates caregivers in providing care.

[0024] It is worth mentioning that, for reference Figure 1 and Figure 2 In this embodiment, the nursing-friendly seat device 3 includes a first support 301 and a second support 302. The first support 301 is inside, and the second support 302 is outside, and the two are rotatably connected by crossing each other in the middle. Two seat plate parts 306 are provided between the top crossbars of the two. A seat cushion 305 is fixedly installed on the upper surface of the seat plate part 306. The surface of the seat cushion 305 is provided with an elliptical concave cavity to facilitate the patient to sit down. Each seat plate part 306 is provided with an open rotating part 307, and the open rotating part 307 is respectively... The rotating parts 307 are rotatably mounted on the corresponding crossbars to form an opening and closing mechanism. Each of the rotating opening parts 307 is provided with a limiting component 310 between itself and the crossbar. The limiting component 310 limits the seat plate part 306. When discharge is required, the limiting component 310 is opened to open both seat plate parts 306. The limiting component 310 includes a protrusion 312 on each rotating opening part 307, with a through groove 313 through which a limiting piece 315 is slidably mounted. The crossbar is provided with a limiting groove 311, and the bottom end of the limiting piece 315 can be embedded in the limiting groove 311 to form a limiting position. Circular cavities 314 are respectively provided on both sides of the sliding groove opening 313. Two guide posts 316 are fixedly provided on the end cap of the limiting piece 315. The guide posts 316 are slidably connected in the circular cavities 314, and an elastic reset component, which can be a spring, is connected between the lower end of the guide post 316 and the lower side wall of the circular cavity 314. This allows the patient to simply lift their buttocks slightly when they need to defecate. The limiting plates 315 on both sides are pulled out, allowing the seat plate 306 to flip open. On the front side, a front support 304 is fixedly installed between the crossbar at the top of the first bracket 301 and the second bracket 302. The front support 304 can hold the patient's thigh root, so that the patient will not be unstable when the seat plate 306 is flipped open, and can defecate stably. Compared with traditional wheelchairs, the patient does not need to move to the toilet to defecate, which is very convenient and patient-friendly. It also makes it easier for caregivers to clean up after defecation.

[0025] In order to apply an opening degree to the seat plate portion 306 when it is flipped open, and at the same time drive the two seat plate portions 306 to reset, in this embodiment, a connecting portion 308 is provided on the rear end face of each seat plate portion 306, and a corrugated elastic band 309 is fixedly connected between the two connecting portions 308. When the two seat plate portions 306 are flipped open, the corrugated elastic band 309 is stretched. The maximum opening degree is reached when stretched to its limit. After excretion, as long as the buttocks are lifted, the corrugated elastic band 309 retracts and resets, allowing the two seat plate portions 306 to reset again. Then, the limiting components 310 on both sides are closed for limiting, which is very convenient.

[0026] In another embodiment, a crotch portion 303 is fixedly installed between the crossbar at the top of the first bracket 301 and the second bracket 302.

[0027] In practice, the patient sits on the seat cushion 305 with their groin against the front support 304. When the patient needs to urinate, they first lift their buttocks slightly and pull out the limiting plates 315 on both sides, causing the seat cushion 305 to disengage from the limiting groove 311. With the limiting plates disengaged, the seat plate 306 flips down and opens, and the corrugated elastic band 309 stretches and tightens to prevent the seat plate 306 from opening too wide, causing the patient's buttocks to be completely suspended. After the patient finishes urinating, the caregiver cleans the area, and finally the patient lifts their buttocks back to their original position. This process is very efficient and convenient.

[0028] It should be emphasized that the embodiments described in this utility model are illustrative rather than limiting. Therefore, this utility model is not limited to the embodiments described in the specific implementation. Any other implementation methods derived by those skilled in the art based on the technical solutions of this utility model are also within the scope of protection of this utility model.
