The controller 2 receives signals from the myoelectric sensor 25 to control the working state of the electric retractor 26 .
[0040] The myoelectric sensor 25 and the electric retractor 26 are both existing technologies. The myoelectric sensor 25 is used to detect bioelectric signals when the patient's leg muscles spasm, and the electric retractor 26 is used to reel in and release the connecting rope 21.
[0041] Reference Figure 4 、 Figure 5 and Figure 7 , and also includes multiple restraint belts 15. Both sides of the bed frame 3 are fixedly connected to the sliding rods 4. The two ends of the restraint belt 15 are rings, and they are slidably connected to the two sliding rods 4 one by one. The restraint belt 15 is installed with an adjustment buckle 14, and the restraint belt 15 adjusts its own length through the adjustment buckle 14.
[0042] The restraint belt 15 is slid on the sliding rod 4 through the ring, which makes it easy to adjust the position of the restraint belt 15 and move it to different positions according to treatment needs. After moving to the appropriate position, the tightness of the restraint belt 15 is adjusted through the adjustment buckle 14 on the restraint belt 15. Multiple restraint belts 15 form an overall restraint effect on the patient, providing more comfortable contact while ensuring that the patient is fixed and stable.
[0043] Extension plates 7, two extension plates 7 are rotatably connected to both sides of the bed frame 3 in a one-to-one correspondence, and are used to place the patient's arms.
[0044] The extension plate 7 is fixedly connected to a rotating shaft 8 on one side close to the bed frame 3. The rotating shaft 8 is rotatably sleeved on the sliding rod 4. The extension plate 7 is fixedly connected to a hand fixing belt 9 for fixing the patient's wrist.
[0045] Two left buckles 11 and two right buckles 12 are fixedly connected to the mattress 5. The two left buckles 11 are located on both sides of the patient's left shoulder, and the two right buckles 12 are located on both sides of the patient's right shoulder. Shoulder straps 13 are clamped on the two left buckles 11 and the two right buckles 12.
[0046] An extension buckle 10 is fixedly connected to each of the two extension plates 7 , and the extension buckle 10 is snap-fitted with the end of the shoulder strap 13 .
[0047] When the present invention is used, the lifting platform 1 is adjusted to work by the controller 2 , and the output end of the lifting platform 1 drives the bed frame 3 and the mattress 5 thereon to move up and down, so as to facilitate the placement of the patient on the mattress 5 .
[0048] The patient lies on the mattress 5, and the medical staff fixes the patient's head in a special headrest 6 to prevent the patient's head from moving.
[0049] At this time, the patient's waist and abdomen are located on the fixing frame, the waist frame 16 on the fixing frame is buckled to fix the patient's waist, and the abdomen belt 17 is buckled to fix the patient's abdomen, so that the patient's waist and abdomen are comfortably fixed.
[0050] When it is necessary to adjust the posture of the patient's waist, abdomen, thighs and feet, place the patient's feet on the footrest 24, buckle the knee strap 23 on the patient's knee, and use the knee strap 23 to limit the patient's knee joint to avoid excessive flexion and extension or rotation, thereby reducing the risk of secondary injury.
[0051] When the patient's waist and abdomen need to be lifted, the angle between the fixing frame and the first connecting rod 18 is adjusted, and after the angle is adjusted, the pin connection and locking are carried out through the pin shaft and the pin hole, so that the ends of the fixing frame and the first connecting rod 18 facing away from each other are against the mattress 5, and the connection between the two is suspended in the air, so that the two form an arch structure at a certain angle. When the patient lies on the fixing frame and the first connecting rod 18 of the arch structure, his waist and abdomen are lifted, which facilitates medical staff to perform corresponding medical operations.
[0052] When the patient needs to bend his knees, the fixing frame and the first connecting rod 18 are flattened and locked, the angle between the first connecting rod 18 and the second connecting rod 19 is adjusted, and after the angle is adjusted, they are connected and locked through the pin shaft and the pin hole. The end of the second connecting rod 19 away from the first connecting rod 18 is suspended in the air. Under the pressure of the patient's own gravity on the fixing frame and the first connecting rod 18, the second connecting rod 19 maintains a stable single-end suspended state. At this time, the inner thigh of the patient is placed on the second connecting rod 19, so that the patient keeps his knees bent, which is convenient for medical staff to perform corresponding medical operations.
[0053] The opposite ends of the fixing frame and the second connecting rod 19 can be placed against the mattress 5, so that the first connecting rod 18 is suspended as a whole. When the patient lies on the posture adjustment mechanism, the area near the buttocks is suspended, making it easier for medical staff to perform corresponding medical operations.
[0054] The patient's waist, abdomen, buttocks and legs can be placed in different postures through the fixing frame, the first connecting rod 18 and the second connecting rod 19, providing more freedom of choice to facilitate the needs of treatment or testing. The fixing frame, the first connecting rod 18 and the second connecting rod 19 directly provide support for the patient, and the patient does not need to exert force to maintain the required posture by himself, thereby improving the stability of the patient when he is in the corresponding posture, effectively dispersing bone stress, reducing the risk of fracture end displacement, and dynamically adjusting the angle to facilitate inspection.
[0055] The patient's calf is located between the knee brace 23 and the foot rest 24. Through the contraction or stretching of the spring 22, the foot rest 24 can be well fitted to the patient's foot, adapting to patients with different leg lengths. In different postures of the patient, the elastic force of the spring 22 provides support for the patient's foot and calf, reducing the force burden on the patient's calf and foot in different postures.
[0056] A myoelectric sensor 25 is provided below the knee brace 23. The myoelectric sensor 25 is in close contact with the joint below the knee and can receive bioelectric signals more quickly. Some patients may experience nerve irritation or post-traumatic joint stiffness after undergoing orthopedic surgery, which may cause involuntary twitching of the lower limbs and continuous muscle spasms. At this time, the myoelectric sensor 25 receives the bioelectric signal when the leg spasms. The controller 2 receives the signal from the myoelectric sensor 25 and controls the operation of the electric retractor 26. Its output end reels or releases the connecting rope 21. When the muscle spasms, the connecting rope 21 is instantly released to reduce resistance. When the muscle relaxes, the connecting rope 21 is reeled in to maintain the correction position. Combined with the buffering effect of the spring 22, it has a better protection effect and relieves the patient's pain.
[0057] When the patient's arm needs to be examined, the extension plate 7 is opened through the rotating shaft 8 to flatten the extension plate 7, and then the patient's arm is opened and placed on the extension plate 7, and the wrist is fixed by the hand fixing belt 9 to avoid secondary injury caused by the patient's movement, which facilitates the examination or treatment of the arm.
[0058] The shoulder strap 13 can be inserted into the extension buckle 10, the left buckle 11 and the right buckle 12 respectively to achieve different fixing effects.
[0059] Inserting one end of the shoulder strap 13 into the extension buckle 10 and the other end into the left buckle 11 or the right buckle 12 on the other side of the upper arm can assist the hand fixing belt 9 in restraining the patient's upper arm, reduce the patient's movement, and improve the examination effect.
[0060] When the left shoulder strap 13 is inserted into the two left buckles 11 and the right shoulder strap 13 is inserted into the two right buckles 12, the patient's shoulders can be fixed, making it convenient for doctors to examine or treat the corresponding parts.
[0061] The two shoulder straps 13 are cross-inserted into the corresponding left buckle 11 and right buckle 12 to form a cross fixation at the patient's chest. Combined with the auxiliary fixation of the restraint belt 15 and the abdominal belt 17, the patient's movement can be restricted to the greatest extent, achieving the most secure fixation effect.
[0062] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
