Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical device research, and in particular to a perioperative muscle training auxiliary device. Background Art
[0002] The perioperative period refers to the period surrounding the operation. The perioperative period is the entire process surrounding the operation, starting from the patient's decision to undergo surgical treatment, to surgical treatment and basic recovery, including a period of time before, during and after the operation. Specifically, it refers to the period from the time the surgical treatment is determined until the treatment related to this operation is basically completed.
[0003] In the late perioperative period, which is a period of time after surgery, patients need to actively carry out rehabilitation exercises to restore muscle function to avoid affecting their later life. The current exercise method is generally to achieve recovery of muscles in various parts through walking, standing and lifting heavy objects.
[0004] However, the current common training methods are insufficient for the back muscles, but the back muscles are one of the most important muscle groups. Their functions mainly include stabilizing the spine, maintaining body balance, protecting the spine, providing energy, improving posture, activating upper limb muscles, improving upper limb strength, improving basal metabolic value, promoting blood circulation, improving back pain and muscle strain and other problems. It is difficult for normal people to perform back muscle training posture, and it will be even more difficult for patients in the late perioperative period.

A rotating plate 40 is hinged between the outer end of the first fixed plate 38 and the rear end of the inner wall of the second fixed plate 39.
[0037] Working principle: the patient can sit on the base 1 of the device with the help of medical staff or on his own. A groove to prevent hard collision is provided at the front edge of the base 1 relative to the patient's knee bend, so as to protect the patient's knee bend from being injured. Then the patient can lean on the arc groove 8. The curvature of the arc groove 8 is set to adapt to the curvature of the patient's back, so as to improve the patient's comfort. A head groove 9 is also provided relative to the position of the patient's head. The head groove 9 is set to adapt to the shape of the back of the human head. When sitting upright, the position of the back of the head is beyond the plane of the back. The setting of the head groove 9 is to protect the patient's head, avoid hard contact, and prevent the patient's head from bending forward when using the device. To protect the health of the patient's cervical spine, when the patient is sitting on the device, the first tightening belt 11 and the fixing ring 10 can be connected together through the plug plate 12 at the end of the first tightening belt 11. After the two are connected, they cooperate with the vertical plate 2 to form an enclosing structure to restrict the patient on the device, and the two first tightening belts 11 are elastic and can adapt to patients with different body shapes. The lower first tightening belt 11 is used to restrict the patient's body to prevent it from falling off the base 1, and the first tightening belt 11 corresponding to the head slot 9 is used to fix the patient's forehead, so that the patient maintains an upright sitting posture, thereby achieving the purpose of restricting the patient's movement posture and ensuring that the movement assisted by the device for the patient can smoothly act on the rehabilitation exercise of the back muscles;
[0038] After sitting down, the patient can pass his arms on both sides through the two second tightening belts 15 on the support plate 4. The material of the second tightening belt 15 is the same as that of the first tightening belt 11. Therefore, when the patient's arms pass through, they can be propped up and thereby limit the position of the patient's upper arms from changing excessively during movement. The patient's forearms can be stuffed into the enclosure 16. Under the restriction of the enclosure 16, the patient's forearms can only bend in the direction of their own body. After determining the position of the forearms, the patient needs to pass his palms through the grips 5, and then use the weight of his arms and a certain amount of his own strength to pull the grips 5 down. The descending grips 5 will drive the guide rods 19 and the limiting balls 20 thereon to descend together. Because the two grips 5 are connected to each other by the connecting rod 6, the patient needs to pull down the two grips 5 synchronously, and there are restrictions on the vertical rod 17 and the movable ring 18. 6 cannot tilt. When the handle 5 is pulled to the lowest position, the multiple plug-in blocks 33 on the first rotating shaft 27 will be squeezed into the block groove 31 at the edge of the opening end of the shaft groove 29. When the block 33 coincides with the corresponding slot 34, the block 33 will pop out and be stuck in the slot 34 under the action of the compression spring 32. During this process, the output end of the motor 26 continues to rotate, but the first rotating shaft 27 at its output end is initially independent, so it will not drive other structures to rotate. At this time, after the plug-in block 33 and the slot 34 are plugged in, the first rotating shaft 27 will squeeze the inner wall of the slot 34 through the plug-in block 33 to make the second rotating shaft 28 rotate synchronously. Even if the plug-in block 33 and the slot 34 do not correspond to each other at the first time when the first rotating shaft 27 is inserted into the shaft groove 29, the two will correspond to each other and plug into each other in the subsequent rotation of the first rotating shaft 27.
[0039] The rotating second rotating shaft 28 will drive the moving seat 36 to move through the half gear 35. The teeth on the half gear 35 occupy less than half of the space on its circumferential outer wall. This design is to prevent the half gear 35 from meshing with the tooth columns 37 on both sides at the same time to cause jamming. During the rotation, the half gear 35 will alternately mesh with the tooth columns 37 on both sides, thereby causing the moving seat 36 to reciprocate in the front and rear directions. The backward movement of the moving seat 36 will drive the two first fixed plates 38 to move backward. Since the second fixed plate 39 cannot move backward, the rotating plate 40 hinged between the first fixed plate 38 and the second fixed plate 39 will rotate in the process. The rotation of the rotating plate 40 will gradually tend to be parallel to the first fixed plate 38. The two second fixed plates 39 will be pushed outward in this change, and the push will cause the second fixed plate 39 to drive the rotating rod 14 to rotate, and then the exercise mechanism 3 connected to the rotating rod 14 will deflect synchronously. The two exercise mechanisms 3 will drive the patient's arms from both sides of the body to the front of the body, so as to achieve an exercise posture similar to chest expansion exercise;
[0040] In addition, during the patient's exercise, if the patient is unable to continue exercising due to exhaustion, he does not need to take too many actions, but only needs to release the palm of the hand that pulls down the handle 5, and the tension spring 25 will pull the slide bar 23 along the rod groove 24 back to its original position, and then the driving mechanism 7 will stop driving the exercise mechanism 3. The upper and lower walls of the insert block 33 are both inclined surfaces, so the up and down movement of the insert block 33 will not be hindered, and the flat outer walls on both sides are used to push the inner wall of the slot 34, so it will not disengage from the slot 34 during rotation.
[0041] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
