Description

Technical Field

[0001] This invention relates to a modular medical care bed and chair, belonging to the field of medical care facilities. Background Technology

[0002] Companion beds are used by family members to accompany and rest patients. Existing companion beds are foldable. One type unfolds to be used as a companion bed and folds down to become a single seat. This type is difficult to accommodate multiple people sitting and resting during the day when relatives and friends visit the patient. Another type unfolds to be used as a companion bed and folds down for storage, such as under the bed board. This type is completely unusable for resting during the day. Regardless of the type, existing companion beds are all one-piece structures and can only appear in one form. Furthermore, existing companion beds cannot be used as wheelchairs. When patients with mobility difficulties need to leave the ward, they can only be moved with the assistance of caregivers or carried by them, which is physically demanding for caregivers. In existing foldable companion beds, the gaps at the folding points are relatively large, resulting in poor comfort for caregivers lying on them. Summary of the Invention

[0003] The purpose of this invention is to provide a modular medical care bed and chair that solves the technical defects of existing care beds, which have limited functionality and cannot simultaneously meet the needs of caregivers for sitting and resting during the day and lying down at night, as well as for convenient movement of patients with limited mobility.

[0004] To solve the above problems, the technical solution adopted by the present invention is: a detachable and modular medical care chair, including a frame, a base module, and a wheelchair module; the base module has a first sliding part and a first flipping part, the first sliding part is slidably disposed on the frame, and the first flipping part is rotatably connected to the first sliding part, and when the first flipping part flips relative to the first sliding part, the first sliding part moves horizontally on the frame; the wheelchair module has a second sliding part and a second flipping part, the second sliding part can move relative to the frame and be supported by the frame or detached from the frame, and the second flipping part is rotatably connected to the second sliding part, and when the second ... the second sliding part moves horizontally on the frame; the wheelchair module has a second sliding part and a second flipping part, the second sliding part can move relative to the frame and be supported by the frame or detached from the frame, and the second flipping part is rotatably connected to the second sliding part, the second sliding part moves horizontally on the frame; the wheelchair module has a second sliding part and a second flipping part, the second sliding part can move relative to the frame and be supported by the frame or detached from the frame, and the second flipping part moves horizontally on the frame. When the second sliding part is flipped, the second sliding part moves horizontally on the frame; wherein: when both the first and second flipping parts are flipped to a horizontal position and the wheelchair module is located on the frame, the first sliding part, the first flipping part, the second sliding part, and the second flipping part form a care bed; when both the first and second flipping parts are flipped to an inclined position and the wheelchair module is located on the frame, the first sliding part, the first flipping part, the second sliding part, and the second flipping part form a multi-person seat; when the second flipping part is flipped to an inclined position and the wheelchair module detaches from the frame, the second sliding part and the second flipping part constitute a freely movable wheelchair.

[0005] This invention comprises a base module and a wheelchair module, wherein the wheelchair module can be detached from the frame. The wheelchair module can be flipped to transform between a caregiver bed and a multi-person seat. When transformed into a caregiver bed, it allows caregivers to lie down and rest. When transformed into a multi-person seat, it allows multiple people to sit and rest, suitable for caregivers and visitors to sit and rest. The wheelchair module in this invention can be detached from the frame and transformed into a wheelchair, allowing caregivers to push and move patients with limited mobility, reducing the labor intensity of caregivers in moving patients. This invention takes into account multiple needs, including multi-person seating during the day, lying down at night, and moving patients with limited mobility.

[0006] As a further improvement of the present invention, the first sliding part includes a first sliding frame, a bed plate A and a first sliding drive device. The first sliding frame is slidably mounted on the frame, and the first sliding drive device is mounted on the frame for driving the first sliding frame to move horizontally on the frame. The bed plate A is disposed on the first sliding frame. The first flipping part includes a first flipping frame, a bed plate B and a first flipping drive device. The first flipping frame is rotatably connected to the first sliding frame, and the first flipping drive device is mounted on the frame and connected to the first flipping frame for driving the first flipping frame to flip relative to the first sliding frame. The bed plate B is disposed on the first flipping frame.

[0007] The first flipping frame in this invention can be placed against a wall. By sliding the first sliding frame on the frame, sufficient space is provided for the first flipping frame to flip between horizontal and inclined. When the first flipping frame is flipped to the inclined state, the base module can be moved as a whole toward one side of the first flipping frame, thereby increasing the space between the invention and the hospital bed. The invention is equipped with a first flipping drive device to drive the first flipping frame to flip, which facilitates the conversion of the invention between a companion bed and a multi-person seat.

[0008] As a further improvement of the present invention, at least two parallel first sliding grooves are provided on the first tilting frame, and a first guide post is provided in the first sliding groove. The bed plate B is fixed to one end of the first guide post. Pushing the bed plate B to move relative to the first tilting frame, the first guide post can move along the length direction of the first sliding groove in the first sliding groove. The first tilting drive device is one or more electric cylinders. The cylinder body of the electric cylinder is rotatably connected to the frame, and the piston rod of the electric cylinder is rotatably connected to the first tilting part. The piston rod of the electric cylinder extends and retracts to drive the first tilting frame to tilt.

[0009] In this invention, the bed board B can be moved on the first flip frame. When the invention is converted into a multi-person seat, the distance between the bed board B and the bed board A is increased by moving the bed board B, which makes it easier for the first flip frame to flip upward. When the first flip frame is flipped to a horizontal state, the distance between the bed board B and the bed board A can be reduced by moving the bed board B, so that the gap between the bed board B and the bed board A of the companion bed is smaller, and the comfort of lying on it is improved.

[0010] As a further improvement of the present invention, the width of the lower part of the first sliding groove is greater than the width of the upper part, the diameter of the lower end of the first guide post is greater than the diameter of the upper end, and the lower end of the first guide post is located in the larger part of the lower width of the first sliding groove.

[0011] In this invention, the lower diameter of the first guide post is larger than the upper diameter, and the width of the lower part of the first sliding groove is larger than the upper width, so that the first guide post will not detach from the first sliding groove, ensuring that the bed board B can only move relative to the first tilting frame.

[0012] As a further improvement of the present invention, at least two guide bars are arranged parallel to each other on the top of the frame, and guide grooves corresponding to the number and position of the guide bars are provided on the first sliding frame, and the guide bars can move in the guide grooves; a rack is fixed at the bottom of the bed plate A, and the first sliding drive device is a drive motor, and a gear is installed on the output shaft of the drive motor, and the gear meshes with the rack for transmission.

[0013] The present invention drives a gear to rotate via a drive motor. The engagement of the gear and the meshing of the meshing bar drives the first sliding frame to move horizontally on the frame. The cooperation between the guide bar and the guide groove guides the movement of the first sliding frame.

[0014] As a further improvement of the present invention, the second sliding part includes a second sliding frame and a seat plate A. The bottom end of the second sliding frame is provided with a plurality of lower rollers supported by the ground, and a plurality of upper rollers are rotatably provided on the upper part of the second sliding frame. The upper rollers can roll on the top of the frame. The seat plate A is disposed on the second sliding frame. The second flipping part includes a second flipping frame, a seat plate B and a second flipping drive device. The seat plate B is rotatably connected to the seat plate A. The second flipping drive device is mounted on the second sliding frame and is used to drive the seat plate B to flip relative to the seat plate A.

[0015] In this invention, the lower roller on the second sliding seat is supported by the ground. When the wheelchair module is used as a wheelchair, it can roll on the ground to move its position, while the upper roller can move on the frame, making it convenient for the invention to be detached from the frame when used as a wheelchair.

[0016] As a further improvement of the present invention, at least two parallel second sliding grooves are provided on the second tilting frame, and a second guide post is provided in the second sliding groove. The seat plate B is fixed to one end of the second guide post, and the seat plate B is pushed to move relative to the second tilting frame. The second guide post can move only in the second sliding groove along the length direction of the second sliding groove. The second tilting drive device is one or more hydraulic rods. The cylinder of the hydraulic rod is rotatably connected to the second tilting frame, and the piston rod of the hydraulic rod is rotatably connected to the second sliding frame. The extension and retraction of the piston rod of the hydraulic rod is used to drive the second tilting frame to tilt.

[0017] This invention creates a second sliding groove on the second tilting frame, and a second guide post fixed to the seat B moves within the second sliding groove, allowing the seat B to move relative to the second tilting frame. By increasing the distance between the seat B and the seat A, the second tilting frame can be tilted upwards more easily. When the second tilting frame is tilted to a horizontal position, the distance between the seat B and the seat A can be reduced by moving the seat B, making the gap between the seat B and the seat A of the companion bed smaller, further improving the comfort of the caregiver lying on it.

[0018] As a further improvement of the present invention, two handles are fixed on the side of the second tilting frame away from the second sliding part. The two handles and the seat plate B are respectively located on both sides of the second tilting frame, and the handles are perpendicular to the second tilting frame.

[0019] The present invention provides a handle on the second tilting frame, allowing caregivers to move the wheelchair. When the patient is sitting in the wheelchair, the caregiver can push the wheelchair to move it by holding the handle.

[0020] As a further improvement of the present invention, an armrest is rotatably provided on each side of the second sliding frame. When the wheelchair module moves and detaches from the frame, the armrest flips upward and connects with the tilted second tilting frame. A locking structure is provided at the connection between the second tilting frame and the armrest. The present invention improves safety when using the wheelchair by rotatably providing armrests on both sides of the second sliding frame.

[0021] As a further improvement of the present invention, a slide is provided on the top of the frame, and the upper roller can roll along the slide. At least one groove is formed in the slide that can cooperate with the lower part of the upper roller. The two sides of the groove transition with the arc of the slide.

[0022] The present invention facilitates the movement of the wheelchair module on the frame by opening a slide rail on the top of the frame and cooperating with the upper roller, while the groove ensures that the wheelchair module will not easily move off the frame when used as a multi-person seat or a care bed.

[0023] In summary, the beneficial effects of this invention are as follows: This invention consists of a frame, a base module, and a wheelchair module. The wheelchair module can be quickly detached from the bed to form an independent wheelchair, allowing the patient to move freely within the ward. When the wheelchair module and the base module are coupled and reset, they combine to form a flat and comfortable companion bed for caregivers to rest at night. During the day, it can be converted into a multi-person seat to effectively save ward space, thus meeting the multiple needs of daytime multi-person seating, nighttime lying down, and movement of patients with limited mobility.

[0038] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0039] like Figures 1 to 3 , Figure 5 as well as Figure 8 and Figure 9 The modular medical chair shown includes a frame 1, a base module 2, and a wheelchair module 3.

[0040] like Figure 3 , Figure 5 and Figure 8As shown, the base module 2 has a first sliding part 21 and a first flipping part 22. The first sliding part 21 is slidably disposed on the frame 1. The first flipping part 22 is rotatably connected to the first sliding part 21. When the first flipping part 22 flips relative to the first sliding part 21, the first sliding part 21 moves horizontally on the frame 1. The upper surface of the first sliding part 21 always remains horizontal. When the first flipping part 22 flips to the horizontal state, the upper surface of the first flipping part 22 and the upper surface of the first sliding part 21 are located on the same horizontal plane. The first sliding part 21 and the first flipping part 22 are spliced ​​together to form part of the bed board of the companion bed. When the first flipping part 22 flips to the state where it is tilted upward away from the first sliding part 21, the first sliding part 21 forms part of the seat board of the multi-person seat, and the first flipping part 22 forms the backrest or part of the backrest of the multi-person seat.

[0041] like Figure 3 , Figure 5 , Figure 8 and Figure 10 As shown, the wheelchair module 3 has a second sliding part 31 and a second flipping part 32. The second sliding part 31 can move relative to the frame 1 and be supported by the frame 1 or detach from the frame 1. The second flipping part 32 is rotatably connected to the second sliding part 31. When the second flipping part 32 flips relative to the second sliding part 31, the second sliding part 31 moves horizontally on the frame 1, and the upper surface of the second sliding part 31 is always in a horizontal state. When the second flipping part 32 flips to a horizontal state, the upper surface of the second flipping part 32 and the upper surface of the second sliding part 31 are on the same horizontal plane. When the wheelchair module 3 is not detached from the frame 1, and the upper surfaces of the second sliding part 31 and the first sliding part 21 are on the same horizontal plane, the second sliding part 31 and the second sliding part 21 are connected. The two flip-up parts 32 are spliced ​​together to form part of the bed board of the companion bed. At this time, the first sliding part 21, the first flip-up part 22, the second sliding part 31 and the second flip-up part 32 are spliced ​​together to form the bed board of the companion bed. When the second flip-up part 32 is flipped to the point where its end away from the second sliding part 31 is tilted upward and the second sliding part 31 is not detached from the frame 1, the second sliding part 21 forms part of the seat board of the multi-person seat and the second flip-up part 32 forms part of the backrest of the multi-person seat. When the second flip-up part 32 is flipped to the point where its end away from the second sliding part 31 is tilted upward and the second sliding part 31 is detached from the frame 1, the second sliding part 21 forms the seat board of the wheelchair and the second flip-up part 32 forms the backrest of the wheelchair.

[0042] like Figure 1 and Figure 2 As shown, in this invention, both the first flipping part 22 and the second flipping part 32 are flipped to a horizontal position, and the wheelchair module 3 is located on the frame 1. The first sliding part 21, the first flipping part 22, the second sliding part 31, and the second flipping part 32 form a complete care bed, allowing caregivers to lie down and rest; Figure 3 , Figure 5 and Figure 8 As shown, both the first flipping part 22 and the second flipping part 32 are flipped to an inclined position, and the inclination angles are the same. Simultaneously, when the wheelchair module 3 is located on the frame 1, the first sliding part 21, the first flipping part 22, the second sliding part 31, and the second flipping part 32 form a multi-person seat, allowing multiple people, such as caregivers or visitors, to sit and rest. Figure 10 As shown, the second tilting part 32 tilts to an inclined position, and the wheelchair module 3 detaches from the frame 1. The second sliding part 31 and the second tilting part 32 constitute a freely movable wheelchair. Patients with mobility impairments can sit in the wheelchair and be pushed by caregivers. The remaining parts can still be used as a multi-person seat, such as... Figure 9 As shown.

[0043] like Figure 11 As shown, the frame 1 of this invention includes a connecting frame 11, a first support frame 12, and a second support frame 13.

[0047] like Figure 3 and Figure 8As shown, the first sliding part 21 includes a first sliding frame 211, a bed board A212 with a mattress A, and a first sliding drive device 213. The first sliding frame 211 is slidably mounted on the first support frame 12 of the frame 1. The first sliding drive device 213 is mounted on the connecting frame 11 of the frame 1 and is used to drive the first sliding frame 211 to move horizontally on the frame 1. The bed board A212 is disposed on the first sliding frame 211, wherein the mattress A of the bed board A212 is located above the bed board A212. The first sliding frame 211 of this invention includes a first sliding support frame 2111 and a first support leg 2112. The first sliding support frame 2111 includes two first profiles A21111 and five first profiles B21112. In this invention, the number of the five first profiles B21112 is at least two, but can be more. The first profiles B21112 are perpendicular to the first profiles A21111, and both ends of the first profiles B21112 are fixedly connected to the two first profiles A21111 respectively. The first support leg 2112 includes four first profiles C21121 and three first profiles D21122. One first profile C21121 is fixedly connected to both ends of the two first profiles A21111, and the first profiles C21121 are vertically arranged. Each of the bottom ends of 1 is provided with a sliding roller 21123, wherein the rotation axis of the sliding roller 21123 is parallel to the first profile A21111. The lower part of the two first profiles C21121 located at the same end of the two first profiles A21111 is connected to a first profile D21122. The lower part of the two first profiles C21121 located at the other end of the two first profiles A21111 is also connected to a first profile D21122. The lower part of the first profiles C21121 at both ends of the first profile A21111 away from the second flipping part 32 is connected by a first profile D21122 parallel to the first profile A21111. In this invention, the first profile B21112 is slidably connected to the first horizontal connecting rod 123, so that the first sliding part 21 slides horizontally on the first support frame 12.

[0048] like Figure 3 , Figure 8 and Figure 9As shown, the first flipping part 22 includes a first flipping frame 221, a bed board B222 with a mattress B, and a first flipping drive device 223. The first flipping frame 221 is rotatably connected to the first sliding frame 211. The first flipping drive device 223 is mounted on the frame 1 and connected to the first flipping frame 221, and is used to drive the first flipping frame 221 to flip relative to the first sliding frame 211. The bed board B222 is disposed on the first flipping frame 221. The first flipping frame 221 in this invention includes two first flipping profiles A2211 and five first flipping profiles B2212. The first flipping profiles B2212 are perpendicular to the first flipping profiles A2211, and both ends of the first flipping profiles B2212 are fixedly connected to the two first flipping profiles A2211 respectively. The three first flipping profiles B2212 in the middle are equally spaced, and the other two first flipping profiles B2212 are fixedly connected to the ends of the first flipping profiles A2211.

[0049] like Figure 3 , Figure 8 and Figure 9 As shown, in this invention, the two first flip profiles B2212 of the first flip frame 221 are provided with first sliding grooves 224. The two first sliding grooves 224 are parallel. A first guide post 225 is provided in the first sliding groove 224. The bed board B222 is fixed to the upper end of the first guide post 225. Pushing the bed board B222 to move relative to the first flip frame 221 allows the first guide post 225 to move along the length of the first sliding groove 224. Therefore, the bed board B222 in this invention can move relative to the first flip frame 221, so that when this invention is used as a companion bed, there will be no large gap between the bed board B222 and the bed board A212, improving the comfort of lying on it. In this invention, the width of the lower part of the first sliding groove 224 is greater than the width of the upper part, the diameter of the lower end of the first guide post 225 is greater than the diameter of the upper end, and the lower end of the first guide post 225 is located in the larger part of the lower part of the first sliding groove 224. This structure can ensure that the bed board B222 will not detach from the first flipping frame 221 in use.

[0050] like Figure 2 , Figure 3 , Figure 8 and Figure 9 As shown, in this invention, the first flipping drive device 223 consists of two electric cylinders. The cylinder body of the electric cylinder is rotatably connected to the lower part of the vertical connecting rod 112 of the frame 1, and the piston rod of the electric cylinder is rotatably connected to the first flipping profile B2212 of the first flipping part 22. The piston rod of the electric cylinder extends and retracts to drive the first flipping frame 221 to flip.

[0051] like Figure 3 and Figure 5As shown, the present invention provides guide bars 228 on two of the first horizontal connecting rods 123 at the top of the frame 1. The two guide bars 228 are parallel. Guide grooves 229 are provided on two of the first profiles B21112 of the first sliding frame 211, corresponding to the number and position of the guide bars 228. The guide bars 228 can move within the guide grooves 229. Through the communication and movement of the guide bars 228 and the guide grooves 229, the first sliding frame 211 can move horizontally on the first support frame 12. like Figure 3 and Figure 4 As shown, a rack 227 is fixedly connected between the two first profiles A21111 of the first sliding frame 211. The first sliding drive device 213 is a drive motor, which is mounted on the first horizontal connecting rod 123 of the first support frame 12 via a motor mount. The output shaft of the drive motor is vertically upward, and a gear 226 is mounted on the output shaft of the drive motor. The gear 226 meshes with the rack 227 for transmission. The drive motor drives the gear 226 to rotate. Through the meshing of the gear 226 with the rack 227 and the sliding engagement of the guide bar 228 with the guide groove 229, the first sliding frame 211 moves horizontally on the first support frame 12.

[0052] like Figure 3 and Figure 8As shown, the second sliding part 31 of the present invention includes a second sliding frame 311 and a seat plate A312 with a cushion A.
