Therefore, the specification and drawings are only for the purpose of clearly describing a certain embodiment and do not mean that the composition and / or sequence are necessary.

[0032] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0033] See also Figure 1-Figure 4 As shown, the nursing bed provided in the present application includes: a movable base frame 10, a support frame 20, a bed frame 30, a lifting mechanism 40, a weighing mechanism 50, a backboard angle adjustment mechanism 60 and a leg board angle adjustment mechanism 70 arranged on the bed frame 30, and a bed frame angle adjustment mechanism 80 arranged on the support frame 20.

[0034] The lifting mechanism 40 includes: a first lifting drive component 41 and a second lifting drive component 42. The first lifting drive component 41 and the second lifting drive component 42 are arranged between the movable base frame 10 and the support frame 20. The first lifting drive component 41 and the second lifting drive component 42 can output the rising or falling movement synchronously or asynchronously.

[0035] The movable base frame 10 is usually placed on the ground and is the main supporting structure of other structures of the nursing bed. It can realize the movement of the nursing bed. Specifically, four universal wheels 11 are arranged at the four corners of the bottom of the movable base frame 10 so as to rotate when pushed to realize the movement of the nursing bed.

[0036] Combination Fig. 9 As shown, the first lifting drive assembly 41 and the second lifting drive assembly 42 are arranged between the movable base frame 10 and the support frame 20. When the first lifting drive assembly 41 and the second lifting drive assembly 42 can synchronously output the ascending or descending motion, the support frame 20 is driven to ascend or descend relative to the movable base frame 10. When the first lifting drive assembly 41 and the second lifting drive assembly 42 output the ascending or descending motion asynchronously, for example, when the first lifting drive assembly 41 outputs the ascending motion and the second lifting drive assembly 42 outputs the descending motion, the support frame 20 is tilted relative to the movable base frame 10 along the length direction of the support frame 20, that is, one end of the support frame 20 is higher and the other end is lower along its length direction; when the first lifting drive assembly 41 outputs the descending motion and the second lifting drive assembly 42 outputs the ascending motion, the support frame 20 is tilted relative to the movable base frame 10 along the length direction of the support frame 20, and the support frame 20 is lower at one end and higher at the other end along its length direction.

[0037] The two ends of the bed frame 30 along the length direction are hinged to the support frame 20 , and the bed frame angle adjustment mechanism 80 is transmission-connected to the bed frame 30 . The bed frame angle adjustment mechanism 80 is used to adjust the bed frame 30 to swing around the hinged position between the bed frame 30 and the support frame 20 .

[0038] In actual application, the patient lies on the nursing bed along the length direction of the bed frame 30. When the bed frame angle adjustment mechanism 80 adjusts the bed frame 30 to swing around the hinge position between the bed frame 30 and the support frame 20, the bed frame 30 can be swung to a first swing position, a second swing position and a horizontal position relative to the support frame 20. When swung to the first swing position, the bed frame 30 is tilted relative to the support frame 20 about the hinge position between the bed frame 30 and the support frame 20 toward one long side of the support frame 20. When swung to the second swing position, the bed frame 30 is tilted relative to the support frame 20 about the hinge position between the bed frame 30 and the support frame 20 toward the other long side of the support frame 20. When swung to the horizontal position, the bed frame 30 is in a horizontal position relative to the support frame 20.

[0039] After the bed frame 30 is tilted toward the two long sides of the support frame 20 respectively relative to the support frame 20, the patient can be kept in a side-lying state to facilitate nursing. When the bed frame 30 is in a horizontal state relative to the support frame 20, the patient can be kept in a lying position.

[0040] In this embodiment, the bed frame 30 is installed on the support frame 20. When the bed frame 30 is in a horizontal state, the bed frame 30 can be raised or lowered by the synchronous rising or falling of the first lifting drive assembly 41 and the second lifting drive assembly 42. When the first lifting drive assembly 41 and the second lifting drive assembly 42 rise or fall asynchronously, the bed frame 30 can be realized in a hanging head supine position and an anti-hanging head supine position, that is, the patient can be tilted from the head to the feet. In the hanging head supine position, the head is at the lower end and the feet are at the higher end; in the anti-hanging head supine position, the head is at the higher end and the feet are at the lower end, thereby facilitating the care of the patient.

[0041] The bed frame 30 is provided with a fixing plate 31, a back plate 32, a first leg plate 33 and a second leg plate 34. The fixing plate 31 is fixed to the bed frame 30, the back plate 32 is located on one side of the fixing plate 31, one side of the first leg plate 33 is hinged to the other side of the fixing plate 31, and one side of the second leg plate 34 is hingedly connected to the other side of the first leg plate 33. A connecting rod 35 is also provided between the other side of the second leg plate 34 and the support frame 20, one end of the connecting rod 35 is hinged to the support frame 20, and the other end of the connecting rod 35 is hingedly connected to the other side of the second leg plate 34. A dark box placement rack 36 is detachably connected to the back of the back plate 32. The dark box placement rack 36 is used to place a dark box for taking X-rays, and a plurality of through holes 320 are provided on the back plate 32.

[0042] In this embodiment, when the patient lies on the nursing bed, the patient's back rests on the backboard 32, the patient's buttocks sit on the fixing board 31, the patient's thighs are located on the first leg board 33, and the patient's calves are located on the second leg board 34. When the patient is X-rayed, the X-rays pass through the human body through the through hole 320 and are captured by the dark box, thereby forming an image on the dark box, thereby X-raying the patient can be performed.

[0043] The backboard angle adjustment mechanism 60 is in transmission connection with the backboard 32, and is used to adjust the angle of the backboard 32 relative to the bed frame 30. The leg board angle adjustment mechanism 70 is in transmission connection with the first leg board 33, and is used to adjust the angle of the first leg board 33 relative to the bed frame 30. Since the second leg board 34 is hingedly connected to the first leg board 33 and connected to the bed frame 30 through the connecting rod 35, the second leg board 34 can adjust the angle synchronously with the first leg board 33.

[0044] like Figure 1 As shown, one side of the first leg board 33 rotates around the hinge position between it and the other side of the fixed plate 31, so that the first leg board 33 changes its angle relative to the bed frame 30, and then the other side of the first leg board 33 rises relative to the bed frame 30, and the second leg board 34 rises accordingly during the angle change of the first leg board 33, and forms a state with a certain angle with the bed frame 30 under the action of the connecting rod 35, so that the patient's legs can be more comfortable.

[0045] like Figure 1 As shown, the weighing mechanism 50 is mounted on the support frame 20, or, as shown Figure 4 As shown, a weighing mechanism 50 is installed on the movable base frame 10, and the weighing mechanism 50 is used to weigh the bed frame 30, and then indirectly weigh the patient, so as to observe the weight change of the patient.

[0046] It should be noted that when the weighing mechanism 50 is installed on the support frame 20, the bed frame 30 above the support frame 20 can be directly weighed to directly obtain the patient's weight. When the weighing mechanism 50 is installed on the movable base frame 10, the support frame 20 and the bed frame 30 and other structures above the movable base frame 10 can be weighed simultaneously, and the patient's weight can be indirectly obtained.

[0047] In this embodiment, the nursing bed can adjust the backrest angle, the first leg board angle, the second leg board angle, the bed frame angle, etc., and perform X-rays of the patient through the dark box placed in the dark box placement rack, which is convenient for patients with limited mobility. The patient's weight can be weighed by a weighing mechanism, thereby realizing multi-functional application and reducing the workload and burden of medical staff or patients' families.

[0048] In the present application, the first lifting drive assembly 41 and the second lifting drive assembly 42 are symmetrically arranged about the center of the support frame 20, so that the support frame 30 can obtain a uniform lifting force or descending force. In a preferred embodiment, the first lifting drive assembly 41 and the second lifting drive assembly 42 have the same structure.

[0049] See also Fig. 9As shown, the first lifting drive assembly 41 and the second lifting drive assembly 42 both include: a lifting and telescopic driving assembly 411, a first lifting link 412, a second lifting link 413, a lifting shaft 414 and a third lifting link 415.

[0050] by Fig. 9 Taking the perspective shown as an example, when the output end of the lifting and telescopic driving assembly 411 is extended, the third lifting link 415 rotates counterclockwise around the hinge position between it and the output end of the lifting and telescopic driving assembly 411, and then the lifting shaft 414 is driven to descend through the third lifting link 415, and the support frame 20 is driven to descend relative to the movable base frame 10 under the action of the first lifting link 412 and the second lifting link 413; when the output end of the lifting and telescopic driving assembly 411 is retracted, the third lifting link 415 rotates clockwise around the hinge position between it and the output end of the lifting and telescopic driving assembly 411, and then the lifting shaft 414 is driven to rise through the third lifting link 415, and the support frame 20 is driven to rise relative to the movable base frame 10 under the action of the first lifting link 412 and the second lifting link 413.

[0051] In this embodiment, the lifting and telescopic driving assembly 411 in the first lifting driving assembly 41 and the lifting and telescopic driving assembly 411 in the second lifting driving assembly 42 can output telescopic motion synchronously or asynchronously, thereby realizing different states of the support frame such as rising, falling, and tilting.
