Description

TECHNICAL FIELD

[0001] The utility model relates to two convenient nursing bed field, especially in a back two convenient nursing bed. BACKGROUND

[0002] With the increasing number of patients who need long-term bed treatment or rehabilitation. Due to the limited self-care ability, these patients are highly dependent on medical, welfare institutions and family care, and their daily care is extremely heavy for medical staff and family members. As an important tool for assisting these patients, the demand for nursing beds continues to grow. The current market nursing bed has back function, that is, through mechanical drive back bed board rises, assist patients from lying to sitting. However, these nursing beds often lack side protection measures during the back process and when the patient is in a sitting position, increasing the risk of the patient falling from the side and reducing the safety and comfort of use.

[0003] Chinese patent (publication number CN219022007U) discloses a nursing bed with back protection function. When the patient lying on it needs to be assisted to back up, the back power unit starts to drive the back frame to rotate around the rotating shaft. The end of the main support on the back frame is slidingly connected with the track on the back of the back bed plate, so that the back bed plate can be lifted up relative to the hip bed plate to assist the patient to change from a lying position (supine position) to a sitting position. Since the side supports are arranged side by side on both sides of the main support and have a length greater than that of the main support, the two side supports will continuously push the back side plates on both sides of the back bed plate to rotate inward relative to the back bed plate during the lifting process of the main support, thereby forming an arched protection structure on both sides of the back bed plate. When the back side plates on both sides of the back bed plate are lifted up, only when the back bed plate approaches the vertical state, the back side plates can form a relatively deep groove relative to the back bed plate. However, when the inclination angle of the back bed plate is small, such as the commonly used 30° inclination angle, the groove formed by the rotation of the back side plates relative to the back bed plate is shallow, resulting in poor protection ability.

DETAILED DESCRIPTION

[0026] In a typical embodiment of the utility model, as shown in Figures 1-3 a back-up nursing bed is provided.

[0027] The main function of a nursing bed with a back-lifting protection function in the prior art is to assist a patient lying in bed to change from a lying position to a sitting position. The back-lifting power unit drives the back-lifting frame to rotate about the rotating shaft 12, thereby driving the back bed plate 1 to rotate and lift upward relative to the buttocks bed plate 6. However, when the back bed plate 1 is tilted at a small angle (such as the commonly used 30° tilt angle), the groove formed by the back side plate 2 rotating relative to the back bed plate 1 is shallow, resulting in poor protection. Based on this, the present embodiment provides a back-lifting and defecation-protective nursing bed. By providing a wedge block 10 on the back side plate 2 that cooperates with the pulley 8 at the end of the side bracket 7, the pulley 8 increases the distance from the back side plate 2 during movement along the wedge block 10, thereby increasing the amount of rotation of the back side plate 2 relative to the back bed plate 1 and increasing the depth of the groove formed by the back bed plate 1 and the back side plate 2, thereby improving the protection capability.

[0028] like Figure 1 As shown, the back-lifting and two-compartment nursing bed primarily comprises a bed frame 4, a bed board 6, and a back-lifting assembly. The bed frame 4 serves as the basic support structure for the entire nursing bed. The bed board 6 comprises a lower body bed board and an upper body bed board. The lower body bed board is mounted to the bed frame 4, while the upper body bed board comprises a back bed board 1 and back side boards 2. The back bed board 1 is hingedly connected to the back side boards 2 on both sides, allowing the back side boards 2 to rotate relative to the back bed board 1. The back bed board 1 is connected to the bed frame 4 via a linkage mechanism, allowing the upper body bed board to rotate relative to the bed frame 4, thereby changing the angle between the back bed board 1 and the lower body bed board.

[0029] The back-lifting assembly is the drive assembly that rotates the upper body deck relative to the lower body deck. It comprises a main frame 3 and a side frame 7 connected to the main frame 3. One end of the main frame 3 is pivotally connected to the bed frame 4, while the other end abuts the back deck 1 via rollers 9. As the main frame 3 rotates relative to the bed frame 4, the rollers 9 at the end roll along the back deck 1, thereby rotating the back deck 1 relative to the lower body deck, thereby lifting the patient's back. One end of the side frame 7 is connected to the main frame 3, while the other end abuts a wedge 10 on the back side deck 2 via pulleys 8. Rotation of the main frame 3 not only propels the back deck 1 via rollers 9, but also propels the back side deck 2 relative to the back deck 1 via the side frames 7 and pulleys 8. Specifically, a wedge 10 is provided on the back side deck 2 to mate with the pulleys 8 at the ends of the side frames 7. The pulleys 8 run along the wedge 10 along their path, increasing the rotational range of the back side deck 2 relative to the back deck 1. The driving member 11 is connected to the main support 3 and is used to drive the main support 3 and the side support 7 to rotate relative to the bed frame 4.

[0030] The structure of wedge 10 as a guide pulley 8 moves, so that in the process of back bed board 1 rotating up, the back side board 2 can rotate a larger amplitude relative to the back bed board 1, thereby increasing the depth of the groove formed by the back bed board 1 and the back side board 2. The increase of the groove depth can provide better support and protection for the patient during the process of getting up, and reduce the risk of the patient falling off the bed. The whole design not only ensures the comfort and stability of the patient during the process of getting up, but also provides enough flexibility to adapt to the needs of different patients.

[0031] As shown in Figure 2 and Figure 3 , the connecting rod mechanism is a double rocker mechanism, and the bed frame 4 is the frame of the double rocker mechanism. The connecting rods of the double rocker mechanism are respectively hinged to the bed frame 4 and the back bed board 1, and the back bed board 1 is the connecting rod of the double rocker mechanism. So that the upper body bed board can retreat relative to the lower body bed board when rotating up, thereby increasing the gap between the upper body bed board and the lower body bed board.

[0032] In the process of getting up, the change of the angle between the back bed board 1 and the lower body bed board of the traditional nursing bed can cause compression to the patient's abdomen. In this embodiment, by adopting a double rocker mechanism as a connecting rod mechanism, the upper body bed board can retreat relative to the lower body bed board when rotating up, thereby increasing the gap between the upper body bed board and the lower body bed board, effectively reducing the compression to the patient's abdomen.

[0033] The connecting rods include first connecting rods and second connecting rods, and the double rocker mechanisms are symmetrically distributed to improve stability and balance. The first connecting rods and the second connecting rods corresponding to the two groups of double rocker mechanisms are respectively hinged to different positions of the bed frame 4 and the back bed board 1, forming a stable quadrilateral structure. One end of the first connecting rod and one end of the second connecting rod are respectively rotatably connected to different positions of the bed frame 4, and the other end of the first connecting rod and the other end of the second connecting rod are respectively rotatably connected to different positions of the back bed board 1.

[0034] The first connecting rods corresponding to the two groups of double rocker mechanisms are located between the second connecting rods corresponding to the two groups of double rocker mechanisms, and a stabilizing rod is connected between the first connecting rods corresponding to the two groups of double rocker mechanisms to enhance the stability of the structure.

[0035] The main support 3 includes a rotating shaft 12, a back lifting rod and a crank arm 15, the back lifting rod and the crank arm 15 are respectively connected to the rotating shaft 12, the two ends of the rotating shaft 12 are respectively rotatably installed on the bed frame 4, one end of the crank arm 15 away from the rotating shaft 12 is connected to the driving member 11, and the driving member 11 is connected to the driving member 11. The action is accepted, so that the rotating shaft 12 can rotate relative to the bed frame 4, so that the back lifting rod connected to the rotating shaft 12 swings, and one end of the back lifting rod away from the rotating shaft 12 is provided with a roller 9, which is driven by the swing of the back lifting rod to push the back bed board 1 to rotate.

[0036] The driving member 11 is connected to the main support 3 and used to drive the main support 3 to rotate relative to the bed frame 4. The driving member 11 can be a telescopic electric cylinder, a hydraulic cylinder or other linear telescopic power device. The toggle arm 15 and the back lifting rod are distributed radially along the rotation shaft 12, and the driving member 11 is a telescopic rod. One end of the driving member 11 is hinged to the bed frame 4, and the other end is hinged to the toggle arm 15. The telescopic action of the driving member 11 is converted into the rotation of the rotation shaft 12, which can drive the toggle arm 15 and the main support 3, thereby completing the back lifting action.

[0037] As shown in Figure 2 and Figure 3 , the rotation shaft 12 is the core component of the main support 3. When the bed frame 4 is arranged horizontally, the axis of the rotation shaft 12 is also horizontally distributed. The rotation shaft 12 plays a role in connecting and supporting the back lifting rod and the toggle arm 15. The two ends of the rotation shaft 12 are rotatably installed on the bed frame 4, so that the main support 3 can rotate relative to the bed frame 4. One end of the back lifting rod is connected to the rotation shaft 12, and the other end is provided with a roller 9. The wedge block 10 is installed on the side of the back side plate 2 facing the bed frame 4. The back bed plate 1 is provided with a guide rail for abutting the roller 9. The shape and position of the guide rail are designed to ensure that the roller 9 can smoothly drive the back bed plate 1 to perform the back lifting action during rolling. The roller 9 cooperates with the guide rail on the back bed plate 1. When the main support 3 rotates, the roller 9 rolls on the guide rail, thereby driving the back bed plate 1 to perform the back lifting action.

[0038] The toggle arm 15 is connected to the rotation shaft 12, but is spaced apart from the back lifting rod in the axial direction of the rotation shaft 12 and is located at a different circumferential position of the rotation shaft 12. The end of the toggle arm 15 away from the rotation shaft 12 is connected to the driving member 11, and the rotation of the toggle arm 15 and the entire main support 3 is driven by the telescopic movement of the driving member 11.

[0039] The side support 7 is connected to the main support 3 and has a cantilever structure. At the end of the side support 7, a pulley 8 is installed. The pulley 8 cooperates with the wedge block 10 on the back side plate 2. When the main support 3 rotates, the pulley 8 slides on the wedge block 10, thereby pushing the back side plate 2 to rotate and forming a side protection for the user. The wedge block 10 is installed on the side of the back side plate 2 facing the bed frame 4. Its shape is designed so that when the pulley 8 slides on it, a certain pushing force can be generated to push the back side plate 2 to rotate.

[0040] By designing the wedge block 10 and the linkage mechanism, the back lifting process is smooth, comfortable and stable, which can improve the user experience of the patient and make the patient feel more comfortable and relaxed during nursing, thereby being conducive to the rehabilitation and recovery of the patient.

[0041] By designing the cooperation of the roller 9 and the guide rail, and the driving of the telescopic rod to the crank arm 15, the stability and controllability of the back lifting action are realized, which helps to reduce the impact and discomfort of the user's body during the back lifting process. By designing the cooperation of the side support 7 and the wedge block 10, when the main support 3 rotates, the side support 7 can automatically push the back side plate 2 to rotate, forming a side protection for the user, increasing the safety of the nursing bed and the user's experience.

[0042] The conventional nursing bed lacks side protection during back lifting, and the patient is easy to slide off from the sides of the back bed plate 1, causing accidents. In this embodiment, by designing the back lifting assembly and the back side plate 2, the back side plate 2 can automatically rotate inward to form a protective structure during back lifting, effectively preventing the patient from sliding off.

[0043] In combination Figures 1-3 , the overall working process of the back lifting two-way nursing bed:

[0044] The overall working process of the back lifting two-way nursing bed mainly revolves around its back lifting function. When the patient lying on it needs to be assisted to back lift, the driving part 11 (such as an electric push rod) in the back lifting assembly is started to drive the main support 3 to rotate relative to the bed frame 4. One end of the main support 3 is rotationally connected to the bed frame 4, and the other end is abutted to the back bed plate 1 through the roller 9. With the rotation of the main support 3, the roller 9 rolls on the back bed plate 1, thereby pushing the back bed plate 1 to rotate and lift relative to the lower body bed plate.

[0045] At the same time, the side support 7 connected to the main support 3 also moves together. One end of the side support 7 is connected to the main support 3, and the other end is abutted to the wedge block 10 of the back side plate 2 through the pulley 8. With the rotation of the main support 3, the pulley 8 of the side support 7 moves on the wedge block 10. This movement not only ensures that the side support 7 can move along the predetermined path of the back side plate 2, but also makes the back side plate 2 rotate and lift inward relative to the back bed plate 1 through the abutment and pushing of the pulley 8. During the rotation and lifting of the back bed plate 1, the back side plate 2 also forms a protective structure, effectively preventing the patient from sliding off from the sides of the back bed plate 1 during the back lifting process or in a sitting position.

[0046] In addition, the nursing bed also uses a double rocker mechanism to connect the bed frame 4 and the back bed plate 1, so that the upper body bed plate can be withdrawn relative to the lower body bed plate when rotating and lifting, thereby increasing the gap between the upper body bed plate and the lower body bed plate. Not only does it realize the decompression of the patient's abdomen during back lifting, but also improves the comfort and safety of the patient.

[0047] The above merely describes preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
