Description

Technical fields:

[0001] This application relates to the field of medical bed technology, and in particular to a tilting bed. Background technology:

[0002] The invention patent application CN202010487418.5—a three-fold side-turning nursing bed—includes a lower bed frame and an upper bed frame. The upper bed frame includes a pair of three-fold linkage mechanisms, each comprising a rotating link and a balance link arranged parallel to each other vertically. Both ends of the rotating link and the balance link are connected via swing connecting seats, which are rotatably connected to the ends of the rotating link and the balance link. The lower bed frame has a pair of symmetrically arranged rotating supports, and the pair of three-fold linkage mechanisms are respectively connected to the corresponding rotating supports. The middle portions of the rotating link and the balance link are rotatably connected to the rotating supports. Bed board supports are fixedly connected between the corresponding rotating links and between the swing connecting seats. The invention also includes a drive mechanism for driving the rotating links to rotate.

[0003] This side-turning bed has a three-section structure when it is turned longitudinally. The two sides are horizontal, and the middle part can be turned over. However, it cannot meet the needs of patients who need to be moved quickly. When a patient who cannot be moved is transferred from the hospital bed to the examination bed, such as when a CT scan is needed, the hospital bed carrying the patient needs to be pushed next to the CT scan bed and placed side by side. Although the patented structure can be turned over partially, the side closest to the examination bed is still horizontal. Therefore, multiple people are needed to transfer the patient to the examination bed. Generally, two people are needed on the left side of the hospital bed and one person is needed on the right side of the CT scan bed. The three people move the patient to the examination bed by lifting and pulling the sheet. As the patient moves towards the examination bed, the person on the left side of the hospital bed needs to lie face down on the hospital bed to ensure the patient's movement. At this time, as the arm is extended, the force will become greater and greater. Multiple stops are required to complete the bed transfer. Multiple people are needed to cooperate, especially for heavy patients, and the transfer for examination is quite difficult. Utility model content:

[0004] To solve the aforementioned technical problems, this utility model provides a tilting bed, which addresses the issue that moving the patient requires the cooperation of multiple people and is quite difficult. The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0005] A tilting bed, characterized in that it comprises:

[0006] The first frame, second frame, third frame and bed board are arranged from bottom to top. The third frame is located outside the second frame and is connected by a hinge structure.

[0007] The two curved arms are respectively located on the left and right sides of the second frame, and the two ends of the curved arms are connected to the second frame and the third frame respectively by a hinge structure.

[0008] Power components used to drive the crank arm to rotate around the hinge point;

[0009] Support columns are installed between the third frame and the bed board;

[0010] A lifting mechanism is installed between the first frame and the second frame to drive the lifting of the second frame.

[0011] Furthermore, mounting plates are provided on the front and rear side walls of the second frame through a fixed structure. A hinge shaft is provided on the upper outer side of the mounting plate, and the hinge shaft is connected to the third frame to achieve hinged rotation.

[0012] Furthermore, in a horizontal position, the distance between the bed board and the second frame ranges from 10 to 15 centimeters.

[0013] Furthermore, a crossbeam is fixedly installed on the inner side of the second frame along the width direction. The crossbeam is hinged to the curved arm, and the other end of the curved arm passes through the lower part of the second frame and is hinged to the third frame.

[0014] Furthermore, the power component is an electric actuator, and both ends of the electric actuator are connected to the second frame and the crank arm respectively through a hinge structure.

[0015] Furthermore, the lifting mechanism includes a rotating shaft that is rotatably connected to the first frame, fixed arms A are provided on both sides of the rotating shaft through a fixed structure, fixed arms B are provided on the fixed arms A through a hinge structure, the fixed arms are connected to the second frame through a fixed structure, and a power mechanism for driving the rotating shaft to rotate is also provided.

[0016] Furthermore, the power mechanism includes a linear actuator that is hinged to the first frame. The output end of the linear actuator is provided with a connecting rod through a hinged structure, and the other end of the connecting rod is fixedly connected to the rotating shaft.

[0017] The beneficial effects of this utility model are: by setting up a curved arm to drive the third frame and the bed board to tilt as a whole, personnel located outside the examination bed can transfer the patient to the examination bed with less force by pulling the bed sheet, thus improving the efficiency of moving the bed; by setting up a curved arm, the tilt angle of the bed board can be increased, which can meet the needs of moving patients with larger body weight, thus improving practicality.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the utility model will now be described in further detail with reference to the accompanying drawings and the following embodiments, so that the public can better understand the implementation method of this utility model. The specific implementation scheme of this utility model is as follows:

[0024] A tilting bed includes a first frame 1, a second frame 2, a third frame 3, and a bed board 4 arranged sequentially from bottom to top. A support column 8 is provided between the third frame 3 and the bed board 4. The support column 8 can increase the height between the second frame 2 and the bed board 4, thereby preventing the bottom of the bed board 4 from contacting the second frame 2 and obstructing rotation during rotation, and increasing the rotation angle. The third frame 3 is located outside the second frame 2 and is connected by a hinge structure. Two curved arms 6 are respectively located on the left and right sides of the second frame 2, and the two ends of the curved arms 6 are respectively connected to the second frame 2 and the third frame 3 by a hinge structure. The second frame 2 is provided with a power component 7 for driving the curved arms 6 to rotate around the hinge point. This structural design can increase the tilt angle of the third frame 3, meet the needs of moving heavier patients, improve practicality, and allow personnel located on the right side of the examination bed 11 to transfer patients to the examination bed 11 with less force by pulling the bed sheet, thus improving the efficiency of moving the bed.

[0025] Specifically, the front and rear side walls of the second frame 2 are provided with mounting plates 9 by means of a fixed structure. The upper outer side of the mounting plate 9 is provided with a hinge shaft, which is connected to the third frame 3 to realize hinge rotation.

[0026] It should be noted that in this embodiment, the distance between the bed board 4 and the second frame 2 in the horizontal state is 10 cm. In other embodiments, it can also be 15 cm. While ensuring the stability of the bed structure, the maximum tilt angle of the bed board 4 can reach 22 degrees.

[0027] It should be noted that a crossbeam 10 is fixedly installed on the inner side of the second frame 2 along the width direction. The crossbeam 10 is hinged to the curved arm 6, and the other end of the curved arm 6 passes through the lower part of the second frame 2 and is hinged to the third frame 3.

[0028] Specifically, the power component 7 is an electric push rod. The two ends of the electric push rod are connected to the second frame 2 and the crank arm 6 respectively through a hinge structure. The electric push rod 7 pushes the crank arm 6 to achieve the tilting of the third frame 3.

[0029] It should be noted that, in order to accommodate different heights of the examination bed 11, a lifting mechanism 5 is provided between the first frame 1 and the second frame 2 to drive the lifting of the second frame 2. Specifically, the lifting mechanism 5 includes a rotating shaft 51 that is rotatably connected to the first frame 1. Fixed arms A52 are provided on both sides of the rotating shaft 51 through a fixed structure. Fixed arms B53 are provided on the fixed arms A52 through a hinged structure. The fixed arms are connected to the second frame 2 through a fixed structure. A power mechanism for driving the rotating shaft 51 to rotate is also provided. The power mechanism includes a linear actuator 54 that is hingedly connected to the first frame 1. A connecting rod 55 is provided at the output end of the linear actuator 54 through a hinged structure. The other end of the connecting rod 55 is fixedly connected to the rotating shaft 51, so as to facilitate the adjustment of the height of the bed board 4 according to the height of the examination bed.

[0030] The working principle and process of this utility model are as follows:

[0031] Using the wheels mounted on the first frame 1, the tilting bed carrying the patient is pushed to one side of the CT examination bed 11.

[0032] Start the linear actuator 54. The linear actuator 54 drives the rotating shaft to rotate through the connecting rod 55. The rotating shaft 51 drives the fixed arm A52 to rotate. The fixed arm A52 drives the fixed arm B53 to move upward through the hinge relationship, which in turn drives the second frame 2, the third frame 3 and the bed board 4 to move upward, adjusting the bed board 4 to a height higher than the CT examination bed 11.

[0033] Then, the electric push rod 7 on the left is activated. The electric push rod 7 drives the third frame 3 to rotate to the right through the crank arm 6. The third frame 3 drives the bed board 4 and the patient to tilt to the right to the pre-set position through the support column 8. Then, the person on the right side of the CT examination bed 11 pulls the patient to the examination bed 11 through the bed sheet to complete the bed transfer.
