Description

Technical Field

[0001] This utility model relates to the field of wheelchair care bed technology, specifically a multi-angle adjustable wheelchair care bed. Background Technology

[0002] A wheelchair-operated nursing bed is a medical device that integrates the functions of a wheelchair and a nursing bed. It aims to provide a more convenient and comfortable living and care experience for patients with limited mobility or those requiring long-term bed rest. It facilitates patient movement and participation in daily activities while also serving as a nursing bed, providing a comfortable bedside environment for nursing and rehabilitation. Patients can sit on the wheelchair-operated nursing bed and move manually or electrically to participate in indoor or outdoor activities, improving their self-care abilities. However, the lack of integrated control over the wheelchair-operated nursing bed leads to a poor patient experience and discomfort during different movements, affecting the quality and motivation of nursing care.

[0003] To overcome the aforementioned deficiencies, existing technology (Chinese patent application number 201821603292.8, application date 2018-09-29) provides a wheelchair care bed, comprising a bed body with grooves and a wheelchair placed within the grooves. Guide locking elements are symmetrically arranged on the inner sides of the wheelchair's rear legs. A horizontal axis, supported by the bed frame and aligned with the width of the bed body, is provided on the bed frame near the wheelchair. A pull rod with hooks is arranged along the horizontal axis towards the wheelchair support, engaging with the guide locking elements on the inner sides of the wheelchair's rear legs. When the wheelchair enters the groove of the bed body, it is slowly pushed in until it approaches the bed frame supporting the horizontal axis. Pressing down on the handle causes the pull rod to rotate upwards, pulling the guide locking elements with the hooks and dragging the wheelchair to the rear of the wheelchair groove. The handle then automatically or is positioned, thus positioning the wheelchair. Continuing to press down on the handle disengages the hooks on the pull rod from the upper end of the guide locking elements, and the push rod then pushes the rear of the wheelchair, moving it from the groove of the bed body towards the foot of the bed.

[0004] Whether in hospital wards or home bedrooms, space is often limited. The foldable hand crank can fit snugly against the nursing bed when not in use, greatly reducing its horizontal space occupation and ensuring that medical staff and patients can move freely in the limited space. However, the hand crank of the aforementioned device cannot be adjusted during use, causing the nursing bed to occupy a large space and hindering the daily operations of nursing staff and the movement of patients using wheelchairs. It also increases the risk of collisions and reduces work efficiency. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: By installing the nursing bed 1, anti-slip rails 3, and protective frame 5, the risk of patients falling out of bed when turning over at night is greatly reduced, and the friction force is increased when patients move or change positions on the bed. Figures 1-3 As shown: It includes a nursing bed 1, with a cushioning pad 2 fixedly connected to the upper end of the nursing bed 1, and an anti-slip rail 3 fixedly connected to the upper outer side of the nursing bed 1. The anti-slip rail 3 is symmetrically distributed about the center of the nursing bed 1. A wheelchair 4 is fixedly connected to the lower end of the nursing bed 1. A protective frame 5 is fixedly connected to the upper outer side of the wheelchair 4. A rotating shaft 6 is rotatably connected to the inside of the wheelchair 4 through an angle adjustment component. A fixing frame 7 is fixedly connected to the surface of the rotating shaft 6. The fixing frame 7 is rotatably positioned at the front of the wheelchair 4. A connecting block 17 is fixedly connected to the surface of the protective frame 5 near the fixing frame 7. A limit rod 21 is fixedly connected to the surface of the connecting block 17 through a self-locking component. A sliding block 19 is slidably connected through the limit rod 21.

[0028] When nursing bed 1 is in wheelchair mode, the caregiver pushes nursing bed 1 to the patient's side, assists the patient to sit smoothly in the seat of nursing bed 1, ensuring the patient is sitting upright and comfortable, with both feet placed on the footrests. When nursing bed 1 is in bed mode, the caregiver assists the patient to transfer from other positions to nursing bed 1, helping the patient adjust to a suitable lying position (e.g., ...). Figure 1 and Figure 2 As shown), after the patient is safely transferred to the upper part of the nursing bed 1, the medical staff can adjust the angle of the nursing bed 1. After the angle of the nursing bed 1 is adjusted, the medical staff can retract the hand crank 10 at the lower end of the nursing bed 1. Rotate the hand crank 10 around the sliding rod 9 as the center, so that the hand crank 10 is engaged at the lower end of the nursing bed 1 (as shown). Figure 3As shown, this design avoids damage to the hand crank 10 caused by frequent collisions and squeezing during daily use, extending the service life of the hand crank 10. Furthermore, the protective frame 5 and anti-slip railing 3 prevent patients from accidentally slipping, reducing physical injuries caused by slipping, and mitigating the harm caused to the patient's body by collisions.

[0029] In Example 2, unlike Example 1, the hand crank 10 can be folded using the baffle 13, hand crank 10, and connecting groove 8, allowing for more flexible and free operation by the patient and preventing the hand crank 10 from causing interference when not needed. Figures 4-5 As shown: A sliding rod 9 is slidably connected inside the fixed frame 7, and a connecting groove 8 is provided inside the fixed frame 7. A hand crank 10 is slidably connected to the surface of the sliding rod 9. The hand crank 10 is rotatably disposed on the inner wall of the fixed frame 7. A baffle 13 is fixedly connected to the surface of the hand crank 10. A sliding column 14 is slidably connected inside the baffle 13. A connecting plate 15 is fixedly connected to one end of the surface of the sliding column 14 near the fixed frame 7. One end of a connecting spring 16 is fixedly connected to the surface of the connecting plate 15, and the other end of the connecting spring 16 is fixedly connected to the baffle 13.

[0030] When medical staff use the hand crank 10, they rotate it around the sliding rod 9 as the center, and pull the sliding column 14, causing it to slide inside the baffle 13. Simultaneously, the connecting spring 16 on the surface of the connecting plate 15 retracts towards the surface of the baffle 13. When the baffle 13 on the surface of the hand crank 10 is parallel to the fixing frame 7 (e.g., ...), ... Figure 4 and Figure 5 As shown), when medical staff release the sliding column 14, the connecting spring 16 pushes the sliding column 14 to slide on the surface of the connecting groove 8 inside the fixed frame 7, and the hand crank 10 is engaged with the fixed frame 7. This makes it convenient for medical staff to adjust the nursing bed 1, improving the convenience and adaptability of operation, and ensuring the safety of patients, medical staff and other equipment.

[0031] In Example 3, unlike Example 2, the use of a hand crank 10, a fixed spring 20, and a moving block 18 ensures the trolley maintains stable operation during transport, reducing discomfort and injury risks to patients caused by trolley swaying. Figures 6-7 As shown: the sliding column 14 is slidably disposed inside the fixed frame 7, the hand crank 10 is fixedly connected to the rear side of the fixed block 11, and the fixed block 11 has a locking groove 12 inside, the lower end of the sliding block 19 is fixedly connected to the moving block 18, and the moving block 18 is slidably disposed inside the fixed block 11, and one end of the fixed spring 20 is fixedly connected to the surface of the moving block 18 near the connecting block 17, the other end of the fixed spring 20 is fixedly connected to the connecting block 17, and the surface of the moving block 18 near the protective frame 5 is fixedly connected to the pull rod 22.

[0032] When the hand joystick 10 is folded, the medical staff pulls the movable block 18 on the outside of the protective frame 5, causing the movable block 18 to drive the upper sliding block 19 to slide on the surface of the limiting rod 21 (e.g. Figure 7 As shown), and the fixing spring 20 on the surface of the movable block 18 retracts towards the surface of the connecting block 17. At this time, the medical staff rotates the hand crank 10 with the sliding rod 9 as the center, so that the baffle 13 on the surface of the hand crank 10 is parallel to the outer side of the fixing frame 7. At this time, the medical staff releases the movable block 18, and the fixing spring 20 pushes the movable block 18 to slide on the surface of the locking groove 12 inside the fixing block 11, and makes the movable block 18 fit against the inner wall of the fixing block 11 (as shown). Figure 3 As shown in the figure, the hand joystick 10 can be folded, avoiding damage to the hand joystick 10 caused by frequent collisions and squeezing during daily use, extending the service life of the hand joystick 10, and reducing the repair or replacement costs required due to damage to the hand joystick 10.

[0033] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0034] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
