Technical Field

[0001] This invention relates to the field of rehabilitation medical device technology, specifically a nursing bed that can be connected to a wheelchair to facilitate patient mobility. Background Technology

[0002] In the field of rehabilitation medical devices, nursing beds are the core equipment to assist patients with limited mobility in daily care and rehabilitation, while wheelchairs are an important assistive tool for patient mobility. The two are often used together to meet the dual needs of patients for bed rest and outdoor activities.

[0003] Currently, in existing technologies, nursing beds and wheelchairs are independent devices. When transferring patients between the bed and the wheelchair, caregivers must manually move the patient's body or use additional transfer aids (such as transfer slings, hoists, etc.). In practice, caregivers must first adjust the patient's position, and then multiple people work together to move the patient from the bed to the wheelchair seat. The entire transfer process requires precise control of the patient's balance to avoid bumps or slips.

[0004] However, in the process of realizing the technical solution of this application, the inventors of this application discovered that the above-mentioned technology has at least the following technical problems: the existing transfer methods rely on nursing staff to directly move the patient or use simple tools to assist in the transfer, which is labor-intensive.

[0021] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see the appendix Figure 1 -Appendix Figure 3 This invention provides a nursing bed that can be connected to a wheelchair for easy patient movement. The bed includes a nursing bed body 1, a conveyor belt 2 installed inside the nursing bed body 1, a connecting shaft 3 fixedly connected to one side of the conveyor belt 2, a support backplate 4 fixedly connected to the outside of the connecting shaft 3, baffles 5 fixedly connected to the upper surface of the nursing bed body 1, a sliding groove 6 inside the nursing bed body 1, a spring assembly 7 installed inside the nursing bed body 1, a wheelchair mechanism 9 installed at the rear end of the nursing bed body 1, a rotating assembly 8 installed inside the rear end of the nursing bed body 1, and the wheelchair mechanism 9 is mounted at the rear end of the nursing bed body 1 via the rotating assembly 8. A lifting mechanism 10 is slidably connected inside the sliding groove 6, and one side of the lifting mechanism 10 is connected to the back of the support backplate 4.

[0023] Specifically, in use, the wheelchair mechanism 9 is connected to the tail end of the nursing bed body 1 via the rotating assembly 8, aligning the wheelchair body 91 and the nursing bed body 1 in the same axial position. Through the transmission of gears 82, 83, and 84 within the rotating assembly 8, the conveyor belt 2 inside the nursing bed body 1 is synchronously driven. When the patient lies flat on the nursing bed body 1, their back is supported by the backrest 4, which is fixedly connected to the conveyor belt 2 via the connecting shaft 3. During the movement of the conveyor belt 2, the backrest 4 moves synchronously with it, thus smoothly moving the patient's body along the length of the nursing bed body 1. During this movement, the lifting mechanism 10 slides within the slide groove 6. After the patient moves to the end of the nursing bed body 1, the patient can smoothly transition to the wheelchair body 91 with the cooperation of the first conveyor belt 2 and the second conveyor belt 93 in the wheelchair mechanism 9. This realizes the continuous and horizontal transfer of the patient from the nursing bed to the wheelchair, avoiding the problems of high labor intensity and high operation risk caused by traditional manual lifting, and improving the safety and nursing efficiency of the patient transfer process.

[0024] Please see the appendix Figure 2 The spring assembly 7 includes a sliding rod 72, with a support plate 71 fixedly connected to the top of the sliding rod 72. The outside of the sliding rod 72 is slidably connected to the inside of the nursing bed body 1. A spring 73 is provided between the support plate 71 and the nursing bed body 1, and the spring 73 is sleeved on the outside of the sliding rod 72.

[0025] Specifically, when the patient is lying down, the patient's body weight is transmitted to the support plate 71 through the support back plate 4 and the bed structure. After the support plate 71 is subjected to force, it drives the sliding rod 72 to slide downward, causing the spring 73 sleeved on the outside of the sliding rod 72 to undergo elastic deformation, thereby applying an upward supporting reaction force to the patient. When the patient's position changes, the spring 73 drives the sliding rod 72 and the support plate 71 back to their original position through its own elastic recovery action, which improves the overall stability and safety of use.

[0026] Please see the appendix Figure 2 -Appendix Figure 4The lifting mechanism 10 includes a sliding block 101. The outside of the sliding block 101 slides inside the nursing bed body 1 via a slide groove 6. A connecting rod 102 is fixedly connected to the outside of the sliding block 101. One end of the connecting rod 102 is rotatably connected to a ratchet 103. The tooth end of the ratchet 103 is engaged with a ratchet 104. A connecting assembly 105 is fixedly connected inside the ratchet 104. A handle 106 is fixedly connected to one side of the connecting assembly 105. The connecting assembly 105 includes a support rod 1051, which is divided into two sections and fixedly connected to the outside of the sliding block 101. 51 is connected by a U-shaped block 1052. A rotating rod 1053 is rotatably connected inside the U-shaped block 1052. One end of the handle 106 is connected to the rotating rod 1053. A gear 4 1054 is fixedly connected to the outside of the rotating rod 1053. A rack 1055 is meshed with the tooth end of the gear 4 1054. A sliding groove 2 1056 is opened inside one side of the rack 1055. The support back plate 4 includes a back plate body 41. A concave block 42 is fixedly connected to the back of the back plate body 41. A fixing rod 43 is fixedly connected inside the concave block 42. The outside of the fixing rod 43 slides in the sliding groove 2 1056.

[0027] Specifically, when adjusting the use of the nursing bed, the operator rotates the first handle 106, which drives the rotating rod 1053 to rotate, which in turn drives the fourth gear 1054 to rotate. The fourth gear 1054 meshes with the rack 1055, which drives the rack 1055 to move. The second groove 1056 on one side of the rack 1055 forms a guide with the fixed rod 43, thereby driving the support back plate 4 to rise and fall in a predetermined direction. During the rising and falling process, the ratchet 103 and the ratchet wheel 104 are used to self-lock the first handle 106.

[0028] Please see the appendix Figure 5 and attached Figure 6 The rotating assembly 8 includes a second handle 81, which is externally rotatably connected to the inside of the nursing bed body 1. A gear 82 is fixedly connected to one side of the second handle 81. A gear 83 meshes with the tooth end of one side of the gear 82. A gear 84 meshes with the other side of the gear 82. The gear 84 is internally fixedly connected to the tail shaft of the first conveyor belt 2. The first gear 82, the second gear 83, and the third gear 84 all rotate inside the nursing bed body 1. A mounting block 85 is fixedly connected inside the second gear 83. A mounting groove 86 is provided inside the mounting block 85. A circular buckle 87 is rotatably connected to the bottom end of the mounting block 85. A magnet is provided at the top end of the circular buckle 87. The wheelchair mechanism 9 includes a wheelchair body 91. A baffle 92 is fixedly connected to the upper surface of the wheelchair body 91. A second conveyor belt 93 is installed inside the baffle 92. A mounting strip 94 is fixed to the rotating shaft at one end of the second conveyor belt 93. The shape of the mounting strip 94 matches the shape of the mounting groove 86.

[0029] Specifically, before transferring the patient, the operator pushes the wheelchair body 91 to the rear end of the nursing bed body 1, aligning the mounting strip 94 with the mounting groove 86 inside the mounting block 85. Then, the operator rotates the circular buckle 87, causing it to enclose the mounting strip 94 inside the mounting block 85. The magnet at the top of the circular buckle 87 is then fixed to the top of the mounting block 85, achieving a stable connection between the wheelchair mechanism 9 and the nursing bed body 1. After connection, the operator rotates the second handle 81, which drives the first gear 82 to rotate. The first gear 82 meshes with the second gear 83 and the third gear 84, respectively, for transmission. Gear 3 and 84 do not mesh. Gear 3 drives the tail shaft of conveyor belt 1 to rotate, so that conveyor belt 1 produces a continuous and stable conveying motion. Meanwhile, gear 2 83 maintains the synchronization between wheelchair mechanism 9 and nursing bed body 1 through mounting block 85. In this state, the patient moves towards the tail end under the action of conveyor belt 1 on nursing bed body 1 and forms a docking relationship with conveyor belt 2 93 in the wheelchair body 91 in the same direction. This realizes the smooth transition of the patient from nursing bed to wheelchair, avoiding the problems of uneven force and poor stability in the traditional manual lifting process, making the patient transfer process safer, less strenuous and controllable.

[0030] Please see the appendix Figure 7 -Appendix Figure 9 The back of the wheelchair body 91 is fixedly connected to a lifting assembly 95. A backrest 96 is slidably connected inside the lifting assembly 95. A limit block 97 is fixedly connected to the outside of the backrest 96. A groove is opened inside the bottom end of the backrest 96. The lifting assembly 95 includes a bracket 951. The upper surface of the bracket 951 supports the limit block 97. A rod 952 is slidably connected inside the bracket 951. A grip block 953 is fixedly connected to one end of the rod 952. A second spring 954 is provided between the grip block 953 and the bracket 951. The second spring 954 is sleeved on the outside of the rod 952. The other end of the rod 952 is inserted into the inside of the backrest 96.

[0031] Specifically, during the use of the wheelchair mechanism 9, the backrest 96 is installed on the back end of the wheelchair body 91 via the lifting assembly 95, and the insert rod 952 is axially arranged inside the bracket 951. When the bottom end of the backrest 96 is inside the bracket 951, the spring 954 will drive the insert rod 952 to slide into the groove inside the bottom end of the backrest 96, completing the limit and finally completing the assembly of the backrest 96.

[0032] Working principle: When the patient lies down, the pressure on the support back plate 4 increases. At this time, the connecting component 105 is subjected to force and drives the sliding block 101 to slide inside the slide groove 6. When the patient is fully lying down, the sliding block 101 will slide to the upper surface of the support plate 71, and the sliding block 101 will compress the support plate 71, thereby compressing the spring 73. By moving the ratchet 103, the ratchet 104 and the handle 106 are released from their limits. When the handle 106 is rotated, it will drive the rotating rod 1053 to rotate. The rotating rod 1053 will drive the gear 1054 to rotate. The gear 1054 will drive the rack 1055 to rise, which in turn will drive the backrest body 41 to rise. When the patient rises from a lying position to a sitting position, the backrest body 41 is no longer under pressure, and the connecting component 105 is lifted by the spring 73. At this time, the connecting component 105 is parallel to the slide groove 6 on the nursing bed body 1, and the connecting component 105 and the sliding block 101 move back and forth inside the slide groove 6.

[0033] First, the wheelchair mechanism 9 is connected to the tail end of the nursing bed body 1 via the rotating component 8. The mounting strip 94 on the wheelchair body 91 is inserted into the mounting slot 86 of the mounting block 85 in the rotating component 8, and the circular buckle 87 is rotated. At this time, the magnet in the circular buckle 87 will be attracted to the inside of the mounting block 85, thus realizing the connection between the wheelchair mechanism 9 and the nursing bed body 1. After the conveyor belt 2 93 inside the wheelchair baffle 92 and the conveyor belt 1 2 inside the nursing bed are connected, a smooth conveying path is formed. When the patient needs to be transferred from a lying to a sitting position to a wheelchair, the caregiver operates handle 2 81, which drives gear 1 82 to rotate. Gear 1 82 meshes with gear 2 83 and gear 3 84, thereby driving conveyor belt 1 2 to rotate. The rotation of conveyor belt 1 2 will drive the connecting shaft 3 and the support back plate 4 to move. At this time, the lifting mechanism 10 will slide inside the slide groove 1 6. When gear 2 83 rotates, it will drive the mounting groove 86 and the circular buckle 87 to rotate, which in turn drives the mounting bar 94 to rotate. The rotation of mounting bar 94 will drive conveyor belt 2 93 to rotate inside the wheelchair body 91. By continuously rotating handle 2 81, the patient's body moves in a straight line under the combined action of the two conveyor belts and is finally transferred to the seat of the wheelchair body 91. After the transfer is completed, the adsorption between the circular buckle 87 and the mounting block 85 is released, allowing the mounting strip 94 to detach from the mounting groove 86, thereby separating the wheelchair mechanism 9 from the nursing bed body 1, completing the entire convenient, painless, and single-person-operable transfer process from bed to wheelchair.

[0034] Then, by pulling the backrest 96 upward, the backrest 96 slides inside the lifting assembly 95. When the bottom end of the backrest 96 is inside the bracket 951, the spring 954 will drive the insertion rod 952 to slide into the groove inside the bottom end of the backrest 96, completing the limit and finally completing the assembly of the backrest 96, ensuring the stability and safety of the wheelchair backrest during use.

[0035] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
