A medical treatment bed, as shown in Fig. 1-6, includes a base frame 1, a lifting frame 2, and a bed frame from bottom to top, that is, the bed frame is arranged on the lifting frame, and the lifting frame is arranged on the base frame. The bed frame includes a head bed frame 6, a chest bed frame 5, and a lower body bed frame 4. The head bed frame 6 and the chest bed frame 5 constitute an upper body bed frame. A head bed board 61 is provided on the head bed frame 6 to support the head of a human body, a chest bed board 51 is provided on the chest bed frame 5 to support the upper body trunk of a human body, and a lower body bed board 41 is provided on the lower body bed frame 4 to support the lower body trunk of a human body, such as thighs, calves, feet, etc., and a mattress can be provided on the bed board. In particular, through holes are also provided on the head bed board 61 and the mattress thereon, so that when a patient lies on the bed board, the face will not be squeezed and breathing is convenient. The chest bed frame 5 is always kept in a horizontal state, and the head bed frame 6 is rotatably connected to the chest bed frame 5 by a hinge. The head bed frame can rotate up and down relative to the chest bed frame. A gas spring 54 is hinged on the chest bed frame 5, and the output shaft end of the gas spring 54 is hinged to the head bed frame 6. In this way, the angle between the head bed frame 6 and the chest bed frame 5 can be adjusted by using the gas spring 54 to facilitate the diagnosis or treatment of the patient's cervical spine. The left and right sides of the head bed frame 6 are fixedly connected with a sleeve 62, and a catheter 7 is sleeved in the sleeve 62. The catheter 7 can move along the sleeve 62. A locking nut is provided on the sleeve, and the locking nut can lock the position of the catheter. An arm support 71 is fixedly provided on the top of the sleeve 7 to support the patient's arm.

The width of one end of the lower body bed frame 4 gradually shrinks in the direction approaching the upper body bed frame. For example, the shape of the end of the lower body bed frame close to the upper body bed frame is any one of an arc, an isosceles trapezoid, and an isosceles triangle. In the figure, the shape of the left end of the lower body bed frame is an isosceles trapezoid, and the shape of the lower body bed board matches the shape of the lower body bed frame. This arrangement provides an avoidance space for the left and right rotation of the lower body bed frame. As shown in Fig. 5-6, there is a certain gap between the chest bed frame 5 and the lower body bed frame 4. A sleeve 52 is vertically fixedly connected to the middle part of the side of the chest bed frame 5 near one end of the lower body bed frame. A rotating shaft 43 runs through the sleeve 52 from top to bottom. The rotating shaft 43 can rotate freely relative to the sleeve 52. A semicircular top cap 44 is fixedly connected to the upper end of the rotating shaft 43, and a base 45 is connected to the lower end of the rotating shaft 43. The base 45 and the rotating shaft 43 can be either fixedly connected or rotatably connected. The top cap 44 and the lower body bed frame 4 are rotatably connected through a horizontally arranged pin shaft 47. A first electric push rod 42 is hinged at the bottom of the lower body bed frame 4, and the output shaft end of the first electric push rod 42 is hinged to the base 45. The first electric push rod 42 can drive the lower body bed frame 4 to swing up and down relative to the upper body chest bed frame 5, as indicated by the curved double-directional arrows in Figure 2; at the same time, a second electric push rod 53 is hinged in the chest bed frame 5, and the output shaft end of the second electric push rod 53 is hinged to the side ear 46 on the top cap, so that the second electric push rod 53 can drive the lower body bed frame 4 to swing left and right relative to the chest bed frame 5, as indicated by the curved double-directional arrows in Figure 10, and the up and down swinging and left and right swinging of the lower body bed frame do not interfere with each other. When the lower body bed frame swings, the upper body chest bed frame remains motionless, which significantly improves the patient's freedom of position adjustment on the treatment bed and facilitates medical staff to diagnose and treat patients' lumbar spine diseases.

The structure of the above-mentioned base frame 1 is shown in Figures 7-8. A lifting frame 2, a third electric push rod 11, a control box 8, etc. are installed on the base frame 1. The first electric push rod 42, the second electric push rod 53, the third electric push rod 11, etc. are all electrically connected to the control box 8. The control box 8 can also be connected to a hand controller to facilitate the control of the treatment bed. The base frame 1 is a rectangular frame composed of two long beams 13 and two short beams 12 fixedly connected. A support leg 14 is provided at each corner of the base frame 1, with a total of four legs; a caster 9 is provided on the inner side of each support leg, with a total of four casters, each caster includes a caster shaft 91, the caster shaft freely passes through the short beam 12 in the vertical direction, and there is also an anti-retraction cap on the top of the caster shaft, which can prevent the caster shaft from falling off from the base frame. A caster lifting device 3 that can simultaneously control the synchronous rise or fall of four casters is also provided on the base frame. The connection relationship between the caster lifting device and the caster is shown in Figure 9. The caster lifting device 3 includes a pedal rod 31, a first bent rod 32, a second bent rod 33, a first connecting shaft 34, a connecting rod 35, a third bent rod 36, a second connecting shaft 37, a support column 38, etc., wherein the first bent rod 32 and the second bent rod 36 have the same structure, and their bending spaces can form a semi-enclosure for the short cross beam of the chassis; the first connecting shaft 34 and the second connecting shaft 37 have the same structure, and the first connecting shaft 34 and the second connecting shaft 37 are respectively located below the two short cross beams of the chassis, and both ends of each connecting shaft are rotatably connected to a caster shaft. The pedal rod 31 is located outside the short cross beam at one end of the chassis, and the pedal rod 31 is fixedly connected to the first connecting shaft 34 through the first curved rod 32 and the second curved rod 33, and one end of the pedal rod 31 is connected to the middle of the first curved rod 32, the lower end of the first curved rod 32 is fixedly connected to the first connecting shaft 34, the upper end of the first curved rod 32 is rotatably connected to one end of a connecting rod 35, the connecting rod 35 is located above the chassis and parallel to the long cross beam, the other end of the connecting rod 35 is rotatably connected to the upper end of the second curved rod 36, and the lower end of the second curved rod 36 is fixedly connected to the second connecting shaft 37. A plurality of support columns 38 are provided on the first connecting shaft 34 and the second connecting shaft 37, and the support columns are located below the corresponding short cross beams.

In the initial state, the four legs 14 and four casters 9 on the base frame 1 are all on the ground at the same time. When the foot pedal 31 is stepped on downward, the first curved rod 32 and the first connecting shaft 34 can be driven to rotate, the first curved rod 32 pulls the connecting rod 35, and the connecting rod 35 pulls the third curved rod 36 and the second connecting shaft 37 to rotate, that is, the first connecting shaft 34 and the second connecting shaft 37 will rotate synchronously, and when they rotate, they will drive the multiple support columns 38 fixedly connected thereto to tilt upward, and when the support columns 38 tilt upward, they will support the two short cross beams 12 thereon, thereby supporting the entire base frame to move vertically upward, so that the four legs 14 of the base frame leave the ground, and at this time, only the four casters 9 of the base frame 1 are in contact with the ground, so as to facilitate the movement of the base frame and the entire diagnosis and treatment bed. After the treatment bed is moved into place, the four casters need to be raised so that the four legs touch the ground, so as to stabilize the treatment bed; at this time, hook the footrest 31 with the instep and pull it upward, first lower the base frame so that the four legs touch the ground, at this time the legs and casters touch the ground at the same time, then continue to pull and rotate the footrest, through the connecting rod 35, the first connecting shaft 34 and the second connecting shaft 37 will be driven to rotate and lift upward at the same time, and the lifting will drive the caster shafts of the four casters to move upward, so that the four casters leave the ground, and at this time the base frame is in contact with the ground with the four legs, which is stable and firm. Therefore, the caster lifting device can synchronously control the lifting of the four casters, so that the base frame can flexibly switch between the two states of the legs touching the ground and the casters touching the ground, which is convenient to use, saves time and effort, and is convenient for moving or fixing the treatment bed.

The lower end fulcrum of each transmission frame 2 is respectively connected to a driving arm of the driving frame, the middle fulcrum of each transmission frame is connected to a lower connecting shaft 24 on the base frame, and the upper end fulcrum of each transmission frame is connected to the bed frame (chest bed frame) through an upper connecting shaft 23; two transmission frames 22 form a group, and are connected to a lower connecting shaft 24 and an upper connecting shaft 23 together, and two lower connecting shafts 24 are arranged in parallel and spaced apart on the base frame 1; a third electric push rod 11 is hinged on the base frame, and the output shaft end of the third electric push rod 11 is hinged to the connecting arm 211 of the driving frame. In this way, the third electric push rod 11 can push the driving frame 21 to move, and the driving frame 21 can synchronously drive the four transmission frames 22 to rotate around the lower connecting shaft 24, so as to adjust the height of the bed frame on the transmission frame, so as to facilitate the use of patients and medical staff. Therefore, the base frame and the lifting frame in the present invention are not only suitable for the diagnosis and treatment bed in the present invention, but also can be used for other beds, nursing beds, etc. that need to be moved, fixed or raised and lowered.

The diagnostic and treatment bed described in the present invention can achieve simultaneous lifting and lowering of four casters by one action when it needs to be moved, which greatly reduces the labor intensity of medical staff compared to the bed body operated with four universal wheels. After the bed body is fixed in place, the patient can lie or lie on the bed board, and can also use straps when necessary. Medical staff can adjust the height of the bed body, the left and right traction angle of the lower body, and the up and down folding angle of the lower body through the hand controller; the height of the bed body, the left and right traction of the lower body, and the up and down folding angle of the lower body can be adjusted steplessly by the electric push rod, and the head angle can be adjusted steplessly by the gas spring. Its characteristic is that the lower limb bed surface can be adjusted in four directions of up, down, left, and right, so that the patient's lumbar sacral vertebrae can be pulled to the maximum extent, which is an effective device for treating lumbar diseases.
