Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical equipment, and in particular to a head and cervical spine posture adjustment device and a control method thereof. Background Art
[0002] When the user is undergoing a physical examination, he or she adjusts his or her body posture based on the examination needs to facilitate examination from different angles.
[0003] For the examinee, how to reasonably and quickly adjust the body posture for accurate examination is an important technical issue. When the examinee's strength and posture are uncomfortable, the head, cervical spine, spine and body organs are unevenly stressed, which causes local muscle or bone stress concentration, it is not convenient to examine.
[0004] In the prior art, a physiotherapy bed is used as a common examination device. The examinee lies flat on the integrated physiotherapy bed, and the examiner performs a targeted examination based on the strength and posture of the examinee's physical condition. The integrated physiotherapy bed can be used to adjust and fix the examinee's posture based on the strength and posture of the examinee.
[0005] In order to facilitate separate examinations of different parts of the examinee, the existing one-piece physiotherapy bed can no longer meet the needs of examining different parts of the examinee. The industry has set the physiotherapy bed to be movable and have multiple adjustable panels to support the body of the examinee, which improves convenience compared to the fixed one-piece physiotherapy bed.
[0006] However, when the adjustable physiotherapy bed is in use, it is necessary to have professional inspectors to operate it. The inspectors can judge whether the person being inspected has uneven shoulders, scoliosis, lordosis and internal rotation based on their professional knowledge in the fields of force state and posture correction in anatomy. Then the inspectors can operate the physiotherapy bed to conduct the inspection. Since the operation requires certain operating skills of the inspectors, it is not easy for ordinary people, such as the person being inspected, to master the operating skills in a short time, which brings inconvenience to the operation and increases the workload of the inspectors.
[0007] In addition, the more movable parts an adjustable physiotherapy bed has, the more complex the adjustment is. Even a skilled examiner needs to carefully adjust each parameter according to the examinee's own situation. When the examinee moves his posture, he needs to readjust, which makes the correction and positioning work cumbersome, laborious and time-consuming. Therefore, a new force and posture correction device is needed to solve the above-mentioned deficiencies. Summary of the invention
[0008] In order to solve the technical problems in the above-mentioned prior art that the force state and posture of the physical condition of the person being inspected are difficult to adjust, the operation is cumbersome and the control accuracy is low, the present invention provides an angle adjustment module which is easy to operate, simple in structure and high in control accuracy.
[0009] A head and cervical spine posture adjustment device includes a first support body for supporting a user's body, a second support body for supporting the head and cervical spine, and an angle adjustment module with a transmission mechanism. The angle adjustment module provides a rotational force to the second support body through the transmission mechanism to adjust the relative angle between the second support body and the first support body.
[0010] At the same time, an operation control method using the head and cervical spine posture adjustment device is provided, comprising the following steps:
[0011] Step S01, providing a rotational external force to be applied to the angle adjustment knob of the angle adjustment module;
[0012] Step S02, the transmission mechanism receives the rotational force from the angle adjustment knob and converts it into a horizontal force, and sequentially transmits the horizontal force through the first rotating gear, the first horizontal tooth, the second horizontal tooth, the second rotating gear and the arc gear to convert the horizontal force into a rotational force again to drive the pivot to rotate;
[0013] In step S03, the pivot receives the rotational force from the transmission mechanism and transmits it to the functional surface, thereby driving the functional surface to rotate around the pivot.
[0014] Compared with the prior art, the head and cervical spine posture adjustment device and control method provided by the present invention have the following beneficial effects:
[0015] 1. By adding an angle adjustment module to accurately control the relative angle between the second support body for supporting the head and cervical spine and the first support body for supporting the body, the relative adjustment progress between the two is controlled within the gear pitch as the minimum adjustment unit, thereby greatly improving the adjustment progress;
[0016] Second, a simple angle adjustment knob is used at one end of the angle adjustment module, which is extremely easy to operate. The inspected personnel can operate it in a fool-proof manner without the need for professional technical training. It is simple, fast and easy to operate;
[0017] 3. The transmission of the angle adjustment module is through a horizontal rack and pinion transmission, so that the gears at both ends of the rack transmit force more evenly. The rotation distance brought by the rotation angle is converted into a horizontal position through the gear transmission, and then restored to the rotation angle through the gear transmission. While improving the accuracy, the stopping effect is also improved. When the second support body is adjusted to the set angle, the rotation force is eliminated, and the second support body is effectively fixed to the first support body to avoid the possibility of slipping and improve its reliability.

[0029] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.
[0030] Please refer to Figure 1 , Figure 2 and Figure 3 ,in Figure 1 It is a three-dimensional structural diagram of the head and cervical spine posture adjustment device disclosed in the present invention. Figure 2 yes Figure 1 Another perspective assembly diagram of the head and cervical spine posture adjustment device is shown. Figure 3 yes Figure 2 A partial exploded schematic diagram of a head and cervical vertebrae posture adjustment device is shown. The head and cervical vertebrae posture adjustment device 1 includes a first support body 11, a second support body 13, an angle adjustment module 15 and a base 17. The first support body 11 and the angle adjustment module 15 are respectively fixed to the base 17. The first support body 11 and the second support body 13 are arranged in abutment with each other. The angle adjustment module 15 is fixedly connected to the second support body 13, and transmits a rotational force to drive the second support body 13 to rotate to a set angle relative to the first support body 11.
[0031] The base 17 is used to fix and support the head and cervical posture adjustment device 1. In this embodiment, the base 17 is a single-layer horizontal layer plate. In other embodiments, the base 17 can also be any horizontal plane, which can be an outdoor ground, an indoor ground, other devices or structures with a horizontal surface, etc.
[0032] The first support 11 is used to support the body of the examinee, and the body curve of the examinee matches the surface of the inclined surface 113, which adapts to the lying posture of the human body and avoids the concentration of force caused by the body posture. The first support 11 is an inclined trapezoidal structure as a whole, and includes a bottom surface 111, an inclined surface 113 and a side surface 115.
[0033] The bottom surface 111 is arranged parallel to the horizontal plane, the side surface 115 connects the bottom surface 111 and the inclined surface 113, the inclined surface 113 is arranged to extend obliquely relative to the bottom surface 111, and the transition surface between the two ends of the inclined surface 113 is transitioned in the curve of the human body. In this embodiment, the bottom surface 111 is provided with a plurality of threaded holes, and the first support body 11 is fixed to the base 17 by bolts. In other embodiments, the bottom surface 111 and the base 17 can also be fixed by adhesive or welding.
[0034] The second support body 13 includes a functional surface and two frames. The functional surface 131 is a curved surface that conforms to the outer contour of a human head and the surface curve of the cervical spine, one end of which is suspended and the other end is in contact with the first support body 11. The frames 135 are respectively fixed to the opposite sides of the functional surface 131 and are movably connected to the angle adjustment module 15.
[0035] Please refer to Figure 4 and Figure 5 ,in Figure 4 yes Figure 1 A schematic diagram of the matching relationship between the angle adjustment module and the second support body shown; Figure 5 yes Figure 4 Another schematic diagram of the angle matching relationship between the angle adjustment module and the second support body is shown. The angle adjustment module 15 includes an angle adjustment knob 151, a transmission mechanism 153, a pivot 157, a mounting seat 158 and a guide mechanism 159. Under the fixed support of the mounting seat 158, the angle adjustment knob 151 drives the transmission mechanism 153, which drives the pivot 157 and then drives the second support body 13 to rotate relative to the first support body 11 in space, and the guide mechanism 159 guides the second support body 13 to rotate along a set trajectory range.
[0036] See also Figure 6 ,yes Figure 5 Schematic diagram of the matching relationship between the angle adjustment knob and the transmission mechanism. The angle adjustment knob 151 includes a handheld rotating end 1511, a worm rod 1513 and a bracket 1515. The angle adjustment knob 151 is used to facilitate the operator to apply an external rotational force to the head and cervical spine posture adjustment device 1, thereby adjusting the relative angle between the first support body 11 and the second support body 13. The angle adjustment knob 151 is arranged on the side of the first support body 11, close to the position of the human hand when the human body is in a lying position, for easy operation.
[0037] The bracket 1515 is a square box-shaped structure, having a side end face, an upper end face and a lower end face opposite to the upper end face, and the side end face connects the upper end face and the lower end face. The upper end face and the lower end face are respectively provided with a first mounting hole 15151, and the side end face is provided with a second mounting hole 15153, and the center lines of the first mounting hole 15151 and the second mounting hole 15153 are perpendicular to each other. In this embodiment, the lower end face is provided with a plurality of threaded holes, and the bracket 1515 is fixed to the base 17 by bolts. In other embodiments, the bracket 1515 and the base 17 can also be fixed by adhesive or welding.
[0038] The handheld rotating end 1511 is a cylindrical structure, having an arc side, an upper circular surface, and a lower circular surface opposite to the upper circular surface. The arc side is provided with an anti-slip structure. In this embodiment, the anti-slip structure is a flat-top sawtooth structure. The advantage of such a setting is that when the handheld rotating end 1511 is held by a person, it is not easy to slip and is easy to rotate. In other embodiments, the anti-slip structure can also be a structure that increases contact friction stress, such as a dense corrugated structure.
[0039] The worm rod 1513 is cylindrical in structure, and its diameter is smaller than that of the hand-held rotating end 1511, one end of which is fixedly connected to the lower circular surface of the hand-held rotating end 1511, and the surface of the worm rod 1513 is provided with spiral teeth distributed along the axial spiral. The two opposite ends of the worm rod 1513 are movably mounted on the first mounting hole 15151 through any bearing components, so that the part of the spiral teeth is located between the upper end surface and the lower end surface, and the hand-held rotating end 1511 is located on the other side of the upper end surface.
[0040] When the handheld rotating end 1511 is rotated by an external force, the worm 1513 rotates synchronously with the handheld rotating end 1511 in the same direction, and the worm 1513 and the handheld rotating end 1511 rotate synchronously relative to the bracket 1515 .
[0041] Please refer to Figure 4 and Figure 5 The transmission mechanism 153 includes a turbine 1531, a first gear 1535, a rack 1533, a second gear 1537 and an arc gear 1539. The turbine 1531 and the second gear 1537 are respectively sleeved on opposite ends of a transmission shaft 152, and the transmission shaft 152 is movably mounted on the second mounting hole 15153 of the bracket 1515 through any bearing component, so that the turbine 1531 and the first gear 1535 are respectively located on opposite sides of the side end surface of the bracket 1515.
[0042] The turbine 1531 is in a disc-shaped structure, and the arc surface of the turbine 1531 is provided with helical teeth distributed in an axial spiral pattern. The helical teeth of the turbine 1531 are meshed with the spiral teeth of the worm rod 1513, and the turbine 1531 and the worm rod 1513 cooperate to form a staggered axis gear pair, so that the turbine 1531 and the worm rod 1513 are meshed and connected.
[0043] When the turbine 1531 is meshed with the worm gear 1513 , the second gear 1537 rotates synchronously with the turbine 1531 and the transmission shaft 152 in the same direction, and the turbine 1531 , the transmission shaft 152 and the second gear 1537 rotate synchronously relative to the bracket 1515 .
[0044] The first horizontal tooth pattern and the second horizontal tooth pattern are respectively arranged at two opposite ends of the rack, so that the first horizontal tooth pattern and the second horizontal tooth pattern are an integrated structure. The first gear 1535 and the second gear 1537 are respectively arranged at two opposite ends of the rack 1533, so that the first gear 1535 is meshed and connected with the first horizontal tooth pattern, and the second gear 1537 is meshed and connected with the second horizontal tooth pattern. After the second gear 1537 rotates coaxially with the turbine 1531, it drives the rack 1533 to move horizontally, and then the rack 1533 drives the first gear 1535 to rotate.
[0045] See also Figure 7 ,yes Figure 5 Schematic diagram of the matching relationship between the transmission mechanism and the base. The rack 1533 is provided with a guide groove 15331 on one side close to the bracket 1515 and on the other side opposite thereto. The base 17 is provided with fixed blocks 171 on both sides of the guide groove 15331 corresponding to the rack 1533. The fixed block 171 is provided with a slider 1711 at the position corresponding to the guide groove 15331. The shape of the slider 1711 is provided to match the inner wall of the guide groove 15331, so that the fixed block 171 clamps and fixes the rack 1533, and the slider 1711 and the guide groove 15331 can slide relative to each other. When the rack 1533 is driven by gears from different directions, it will reciprocate relative to the fixed block 171 along the same horizontal direction.
[0046] Along the movement direction of the rack 1533, the base 17 is provided with two limit blocks 173, and the limit blocks 173 are respectively located at opposite ends of the movement path of the rack 1533. When the rack 1533 and the base 17 move relative to each other, if the angle change of the head and cervical vertebra posture adjustment device 1 is about to exceed the safety range, either end of the rack 1533 will abut against the limit block 173, and the relative movement of the rack 1533 will be hindered, preventing the head and cervical vertebra posture adjustment device 1 from rotating beyond the limit, protecting the head and cervical vertebra of the person being examined from being damaged due to accidents such as mechanical failure, and the overall structural reliability of the head and cervical vertebra posture adjustment device 1 is high.
[0047] See also Figure 8 ,yes Figure 5 The schematic diagram of the matching relationship between the first gear and the arc gear is shown. One end of the first gear 1535 is meshed with one end of the rack 1533, and the other end of the first gear 1535 is meshed with the arc gear 1539. When the rack 1533 drives the first gear 1535 to rotate, it will synchronously drive the arc gear 1539 to rotate in the opposite direction relative to the first gear 1535.
[0048] The mounting seat 158 is in the shape of a square column, having two opposite working ends and a main body connected to the working ends. The main body supports the pivot 157 to be arranged horizontally, and the spacing between the two opposite working ends is matched with the axial length of the pivot 157. The opposite ends of the pivot 157 are movably connected to the working ends through any bearing. In this embodiment, the main body is provided with a plurality of threaded holes, and the mounting seat 158 is fixed to the base 17 by bolts, providing a stable supporting force for the angle change of the second support body 13, so that the force transmission of the angle adjustment module 1 is smooth and the angle adjustment is more precise. In other embodiments, the mounting seat 158 can also be fixed to the base 17 by adhesive or welding.
[0049] The arc gear 1539 is fixedly connected to one end of the pivot 157 and is coaxially arranged with the pivot 157. The first gear 1535 is movably connected to the working end of the mounting seat 158 through a rotating shaft with a bearing sleeve. When the arc gear 1539 is driven by the first gear 1535 to rotate, the pivot 157 is driven to rotate synchronously in the same direction, and the arc gear 1539 and the pivot 157 rotate relative to the mounting seat 158.
[0050] The functional surface 131 of the second support body 13 and the frame body 135 are fixedly connected to the pivot 157, and the frame body 135 is extended perpendicular to the pivot 157. When the arc gear 1539 drives the pivot 157 to rotate synchronously in the same direction, the functional surface 131 and the frame body 135 are further driven to rotate relative to the first support body 11, thereby achieving a relative angle setting between the two.
[0051] Please refer again Figure 4 and Figure 5 The guide mechanism 159 includes two horizontal guide rails and two movable guide support shafts. The horizontal guide rails 1591 are fixed to the base 17 in parallel and at intervals, and a hollow long strip slide groove is set in the middle of each horizontal guide rail 1591. One end of the movable guide support shaft 1593 is movably connected to the slide groove 1592, and the other end is movably connected to the frame 135. When the second support body 13 rotates relative to the first support body 11 around the pivot 157, due to the limitation of the slide groove 1592, the movable guide support shaft 1593 supports the frame 135 to rotate smoothly. The guide mechanism 159 realizes the stable rotation of the second support body 13 through the guidance of the movable guide support shaft 1593.
[0052] See also Figures 9A-9C ,in Fig.9A , Fig. 9B and Fig. 9CThe diagrams are respectively schematic diagrams of different states of relative rotation of the first support body 11 and the second support body 13. When the head and cervical spine posture adjustment device 1 is working, it includes the following steps:
[0053] Step S01, providing a rotational external force to be applied to the angle adjustment knob 151 of the angle adjustment module 15;
[0054] Step S02, the transmission mechanism 153 receives the rotational force from the angle adjustment knob 151 and converts it into a horizontal force, and sequentially transmits the horizontal force through the second gear 1537, the rack 1533, the first gear 1535 and the arc gear 1539 to convert the horizontal force into a rotational force again to drive the pivot 157 to rotate;
[0055] In step S03 , the pivot 157 receives the rotation force from the transmission mechanism 153 and transmits it to the functional surface 131 , thereby driving the functional surface 131 to rotate around the pivot 157 .
[0056] Based on this, the rotation of the second support body 13 relative to the first support body 11 is completed.
[0057] Specifically in practical applications, when the person being examined lies or reclines on the head and cervical posture adjustment device 1 , his head corresponds to the functional surface 131 , his body corresponds to the inclined surface of the first support body 11 , and his hands are disposed near the angle adjustment module 15 .
[0058] Compared with the prior art, a non-electric or non-magnetic angle adjustment module is provided in the head and cervical spine posture adjustment device of the present invention to realize the rotation of the second support body relative to the first support body in space. In the specific structural implementation, the force applied by a person holding the handheld rotating end is accurately transmitted in sequence through the meshing transmission of the turbine and the worm shaft, the second gear, rack, first gear and arc gear of the transmission mechanism, thereby realizing precise control of the rotation angle, which is easy to operate and precise. A simple angle adjustment knob is adopted at one end of the angle adjustment module, and the operability is extremely simple. The inspected person can operate it in a fool-proof manner without the need for professional technical training. It is simple, fast and easy to operate.
[0059] More importantly, the transmission of the angle adjustment module is firstly transmitted through the turbine worm gear, and the worm gear is self-locking and can prevent reverse rotation. The gears at both ends of the transmission mechanism make the force transmission more uniform, and the rotation distance brought by the rotation angle is converted into horizontal displacement through the rack, and then restored to the rotation angle through the gear, which improves the accuracy and the stopping effect. When the second support body is adjusted to the set angle, the rotation force is eliminated, and the second support body is effectively fixed to the first support body, avoiding the possibility of slipping and improving its reliability.
