Description

Technical Field

[0001] The present invention belongs to the technical field of traditional Chinese medicine acupuncture auxiliary devices, and relates to an acupuncture treatment bed, in particular to an acupuncture treatment bed suitable for neck and shoulder acupuncture treatment in the prone position. Background Art

[0002] Acupuncture, as a core therapy of traditional Chinese medicine, can regulate the qi and blood circulation and zang-fu functions of the human body by stimulating specific acupoints, and has the therapeutic effects of " dredging meridians, balancing yin and yang, strengthening healthy qi and eliminating pathogenic factors".

[0003] Modern medical research shows that acupuncture can regulate physiological functions through the neuro-endocrine-immune network. Its mechanism of action lies in activating the body's self-healing system, and it has a wide range of adaptability in the fields of pain syndromes (such as cervical spondylosis, lumbar disc herniation), nervous system diseases (such as facial nerve paralysis, sequelae of stroke), digestive system diseases (such as functional gastrointestinal disorders), and immune regulation (such as allergic diseases).

[0004] For acupuncture treatment, patients need to maintain specific postures such as supine, prone or lateral to expose the treatment area, and doctors accurately locate the acupoints for acupuncture operations. The treatment process has high requirements for the stability of the posture, the tolerance of the patient and the convenience of the doctor's operation. In particular, the quality of posture maintenance directly affects the effect of acupuncture qi arrival and the safety of treatment. Patients need to maintain a static posture for a long time (20 - 40 minutes), and any deviation in posture may lead to needle body bending or reduced curative effect.

[0005] The acupuncture bed is an important auxiliary tool for acupuncture treatment, and its functional design directly affects the treatment effect and the patient experience. Conducting acupuncture treatment on an acupuncture bed can easily make the patient's body in a relaxed state, which is convenient for accurate acupuncture operations and improves the acupuncture treatment effect.

[0006] Most acupuncture beds are improved from ordinary diagnosis and treatment beds, and their functions are relatively basic. Similar to other diagnosis and treatment equipment, they mainly focus on the functional design of diagnosis and treatment. For example, CN 119632788A discloses an acupuncture bed for preventing and treating cervical spondylosis. By setting an adjusting device on the acupuncture bed bracket that can flexibly adjust the height of the bed board, the lying height of the patient reaches the optimal acupuncture position. By setting a rigid limiting device to forcibly fix the patient's arm, the patient is in a forced static state, reducing the acupuncture deviation caused by the patient's random movement due to the pain stimulation of acupuncture. However, these designs only consider the convenience of medical staff's operation and overemphasize the diagnosis and treatment effect, and hardly stand from the patient's perspective, rarely considering the patient's own feelings and physical and mental demands, which is likely to exacerbate the patient's physiological-psychological double stress response.

[0007] Although existing acupuncture beds are generally equipped with facial openings and body position support devices, it has been found in actual clinical applications that their designs and functions still have deficiencies. Especially during the acupuncture treatment of the neck and shoulders in the prone position, adverse reactions such as compensatory muscle tension induced by limited movement after the head is fixed have become prominent problems that urgently need to be solved clinically.

[0008] Clinical observations have found that patients bury their faces in the holes and maintain a fixed body position for a long time without change, causing the temporomandibular joint to be forced into a continuous abducted state. During the 20 - 40 - minute treatment process, the electromyographic activity of the masseter muscle increases significantly, objectively causing local fatigue of the ligaments and muscles around the cervical vertebra joints due to compensatory contraction, and then leading to muscle pain or spasm.

[0009] At the same time, during the acupuncture treatment of the neck and shoulders, the cervical spine rotation function is mechanically restricted, the mobility of the C1 - C7 vertebrae decreases, triggering abnormal contraction of the posterior cervical muscles, which will also lead to compound symptoms such as stiffness, numbness, difficulty breathing, and abnormal sweating. Even patients may find it unbearable and end the treatment prematurely, or misattribute the body position discomfort to the ineffectiveness of acupuncture.

[0010] The subjective factor causing the above problems is the "fear - induced immobilization phenomenon" that generally exists during acupuncture. Due to the psychological fear during acupuncture treatment (such as worrying about needle displacement, increased pain, or accidental injury), patients naturally generate psychological defenses, manifested as autonomously inhibiting body activities, thus leading to physiological - psychological interaction reactions such as muscle tension, abnormally increased muscle tone, and rigid body position. This phenomenon is particularly prominent during the prone - position neck and shoulder treatment, directly affecting the acupuncture efficacy and treatment safety.

[0011] The current design logic of acupuncture beds still remains in the functional improvement stage of "taking the doctor as the center" and fails to integrate the concept of human - centered medical care. Therefore, there is an urgent need to develop an acupuncture bed that integrates the functions of dynamic body position adaptation and psychological comfort, which can relieve compensatory muscle tension and fear - induced immobilization while ensuring the accuracy of acupuncture, and fundamentally improve the safety of acupuncture treatment and patient compliance. Summary of the Invention

[0012] The purpose of the present invention is to provide a prone - position neck and shoulder acupuncture treatment bed, which realizes the micro - adaptive adjustment of the cervical spine mobility through a dynamic mechanical compensation support system, effectively relieves compensatory muscle tension and body position discomfort, realizes the dynamic adjustment of muscle tension while maintaining the stability of the treatment body position, and improves the tolerance of acupuncture treatment.

[0013] The basic acupuncture treatment bed is composed of a bracket and a bed board fixedly installed thereon, and a supporting hole for accommodating the human head is opened on the bed board. The prone - position neck and shoulder acupuncture treatment bed of the present invention is improved on this basis and is provided with a dynamic mechanical compensation support system, specifically including: - At least one long strip-shaped receiving groove is provided at the edge of the supporting hole, and rotating shaft holes are formed on the side walls on both sides of the receiving groove; the rotating shaft holes can be arranged at the middle positions of the side walls on both sides of the receiving groove, but more preferably at the inner ends of the side walls of the receiving groove. - A supporting plate adapted to the shape of the receiving groove is provided in the receiving groove. The supporting plate is hinged in the rotating shaft holes of the receiving groove through a rotating shaft integrally formed at its end, and can swing slightly upward around the rotating shaft, and the swing angle thereof is limited to 0° to 10°, more preferably 0° to 5°. - The swing of the supporting plate is driven by a micro linear actuator. The base of the micro linear actuator is fixed to the bed board through a hinge support, and the end of its telescopic rod is hinged to the driving point on the bottom surface of the supporting plate far from the rotating shaft through a ball joint.

[0014] The core design of the above dynamic mechanical compensation support system of the present invention is to utilize the micro elevation angle adjustment (maximum 10°) of the supporting plate at the edge of the supporting hole, and on the premise of ensuring the stability of the acupuncture treatment position of the neck and shoulder, especially the stability of the neck position, a millimeter-level displacement compensation of the head position is achieved, and the purpose of eliminating the tension of the neck muscles and improving the static residual tension of the muscles is achieved by slightly adjusting the position of the human head.

[0015] Further, in order to make the micro swing of the supporting plate smoother and reduce friction, an oil-impregnated bushing can also be press-fitted on the rotating shaft, and the outer diameter of the oil-impregnated bushing is in interference fit with the rotating shaft hole.

[0016] It should be noted that the driving method in the above structure is not the only way to drive the swing of the supporting plate. Any driving structure that can achieve the purpose of driving the supporting plate to swing slightly upward, including but not limited to using hydraulic drive, pneumatic drive, etc., can also be a technical means to achieve the purpose of the present invention.

[0017] Therefore, the present invention also provides another neck and shoulder acupuncture treatment bed based on the prone position, including a bracket and a bed board fixedly installed thereon. The bed board is provided with a supporting hole for accommodating the human head, and also includes the following dynamic mechanical compensation support system: At least one long strip-shaped receiving groove is provided at the edge of the supporting hole, and a supporting plate capable of performing micro elevation angle adjustment around the axis of the pivot pin to adjust the position of the human head is provided in the receiving groove; Support frames are fixedly connected to both sides of the supporting plate, and a limiting arc-shaped guide groove with a central angle of 10° is formed on one side of the center line of the support frames; A support frame is arranged below the bed board, and a bearing support adapted to the support frame is fixedly installed on the support frame. A fixed pivot pin is provided on the side wall of the bearing support, and the pivot pin and the limiting arc-shaped guide groove on the support frame form a swing pair; The swing of the supporting plate is driven by a micro linear driver. The base of the micro linear driver is fixed to the bearing support through a hinge support, and the end of its telescopic rod is hinged to the bottom surface of the supporting plate through a ball joint; The central angle of the limiting arc-shaped guide groove restricts the swing angle of the supporting plate to 0° to 10°.

[0018] More specifically, preferably, the present invention connects the micro linear driver to the side of the bottom surface of the supporting plate away from the limiting arc-shaped guide groove to form a lever-type moment action.

[0019] Furthermore, in order to make the micro swing of the supporting plate smoother and reduce friction, similarly, an oil-impregnated bearing can also be press-fitted on the pivot pin, and the outer diameter of the oil-impregnated bearing is in clearance fit with the limiting arc-shaped guide groove.

[0020] Even further, as a preferred technical solution, the present invention can symmetrically arrange two long strip-shaped receiving grooves at the edge of the supporting hole of the acupuncture treatment bed, and each receiving groove is provided with one of the supporting plates.

[0021] More preferably, the two receiving grooves are symmetrically arranged in the corresponding areas of the human head cheekbones on both sides of the supporting hole.

[0022] More preferably, the present invention drives the two supporting plates by respective independent driving mechanisms. Among them, a synchronous driving method can be adopted to control the synchronous telescoping of the two micro linear drivers on both sides. However, more preferably, the micro linear drivers on both sides are independently driven respectively, and through the alternating micro swings of the supporting plates on different sides, the purpose of fine-tuning the human head in different directions is achieved.

[0023] Even further, the present invention can also be provided with a second receiving groove at the top end of the supporting hole of the acupuncture treatment bed. A swingable second supporting plate is arranged in the second receiving groove and is driven by an independently arranged micro linear driver. The second supporting plate can swing upward to raise the height of the human head and cooperate with the supporting plates on both sides to jointly form a three-dimensional pose adjustment ability. The swing angle of the second supporting plate is limited to 0° to 15°, and the swing amplitude is slightly larger than that of the supporting plates on both sides.

[0024] As a preferred technical solution of the present invention, the outer edge of the supporting plate is designed as a continuous smooth arc surface structure adapted to the arc of the edge of the supporting hole, which can eliminate the discomfort of the patient caused by possible structural mutations while ensuring that the supporting plate is allowed to perform necessary micro swings, and improve the adaptability and comfort of the device.

[0025] As a preferred technical solution of the present invention, the supporting plate and the bed board are entirely circumferentially wrapped with an integrated flexible wrapping layer. Based on the characteristic that the supporting plate only produces a small swing, while this wrapping structure maintains the effective limitation of the supporting plate by the flexible material, it still allows the supporting plate to achieve the expected small displacement relative to the bed board.

[0026] The acupuncture treatment bed of the present invention is particularly suitable for use in acupuncture treatment of the neck and shoulders in the prone position. By integrating an ergonomic optimization structure and a dynamic biomechanical adaptation mechanism, it effectively alleviates the accumulation of muscle static tension caused by the long-term maintenance of the prone position of the patient, promotes muscle relaxation by reducing static residual tension; at the same time, its physiological movement space of the cervical vertebra is only about 3-5°, while ensuring the stability of the treatment position, relying on the synergistic effect of dynamic stability technology, it realizes the dual improvement of the patient's comfort and the diagnosis and treatment effect.

[0034] The following further describes in detail the specific embodiments of the present invention in conjunction with the drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention, so that those skilled in the art can well understand and utilize the present invention, rather than limiting the protection scope of the present invention.

[0035] Therefore, the embodiments described below in conjunction with the accompanying drawings are only a part of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts also fall within the protection scope of the present invention. Similarly, the components of the embodiments described and shown in the drawings of the present invention can also be arranged and designed in various different configurations.

[0036] In the description of the present invention, unless otherwise specified, the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc. is the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship of habitual placement. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation to the present invention.

[0037] In the description of the present invention, it should be noted that, unless otherwise clearly specified and defined, the terms "connected" and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying an order or relative importance or implicitly indicating the quantity of the indicated technical features. The meaning of "a plurality" is two or more, unless otherwise specifically defined.

[0039] The present invention aims at the acupuncture treatment for cervical spondylosis in the prone position, collects the quantitative data of the position-related discomfort symptoms of the acupuncture treatment for outpatients in the prone position, constructs a database for data analysis based on the discomfort sites and degrees of the patients (including physical and psychological tension and anxiety, etc.), and conducts cross-integration in combination with ergonomics to develop a special acupuncture treatment bed suitable for acupuncture treatment of the neck and shoulders, so as to solve the problems of physiological compensatory tension and psychological defensive braking caused by the acupuncture treatment bed based on the patients' own feelings.

[0040] Research findings show that when the human body maintains a static posture, it is not in an absolutely static state. Instead, it achieves muscle relaxation and body dynamic balance through continuous self-posture adjustment. In many cases, although the posture compensation under the regulation of the autonomic nervous system only shows a slight displacement, and the adjustment amplitude is even lower than the visual perception threshold, it can effectively decompose local stress concentration and achieve dynamic regulation of muscle tension. The main reason for the adverse reaction of muscle tension during acupuncture treatment of the neck and shoulders is the autonomic inhibitory posture rigidity and abnormal contraction of local muscle groups caused by the body's own "fear-induced immobilization phenomenon". Therefore, in the present invention, a dynamic mechanical compensation support system is set on the acupuncture treatment bed, and the acupuncture bed described in the following embodiments is constructed. By simulating the physiological micro-motion compensation mechanism of the body posture under the regulation of the autonomic nervous system, bionic dynamic regulation of muscle tension is achieved on the premise of maintaining the reference stability of the treatment posture. Embodiment

[0041] Embodiment 1

[0042] The structure of the neck and shoulder acupuncture treatment bed based on the prone position is as Figure 1 shown, mainly composed of a bracket 1 and a bed board 2 fixedly installed thereon. On the bed board 2, a support hole 3 with a width of about 22 cm is opened in the head area. When the patient lies prone, the head is embedded in the hole, and the facial curve is adapted through the arc contour at the edge of the hole to ensure that there is no compressive occlusion in the nasal cavity and oral area, maintain the smoothness of the natural breathing passage, and at the same time stably fix the head to ensure the safety and accuracy of the acupuncture operation.

[0043] On both sides of the edge of the support hole 3, two Figure 2 shown rectangular accommodating grooves 31 with a width of about 5 cm are symmetrically arranged corresponding to the zygomatic bone area of the head. A rotating shaft hole is opened on the inner side of the side wall of the accommodating groove 31. A support plate 4 adapted to the groove shape thereof is arranged in the accommodating groove 31 and is hinged on the rotating shaft hole.

[0044] The specific connection method of the support plate 4 is as Figure 3 , Figure 4 shown. A rotating shaft 41 press-fitted with an oil-impregnated bushing 401 is integrally arranged on the support plate 4. By press-fitting the oil-impregnated bushing 401 into the rotating shaft hole, the support plate 4 can swing upward around the rotating shaft hole in the accommodating groove 31, so as to adjust the position of the human head through a micro amplitude elevation angle adjustment.

[0045] In addition, the outer side edge of the support plate 4 is designed as a continuous smooth arc surface structure 44 adapted to the edge radian of the support hole 3, and the swing angle of the support plate 4 is limited to 0° to 10°.

[0046] Based on the width of the supporting plate being approximately 5 cm, even if the rotating shaft can be located at the innermost end of the receiving groove, when the supporting plate rotates upward by 5°, the elevation distance of its distal end is approximately 0.44 cm, and the elevation distance when rotating by 10° is only approximately 0.87 cm. Considering the position changes of component assembly and the position changes of the supporting plate for head support, the slight swing of the supporting plate ultimately truly achieves millimeter-level displacement compensation for the head position.

[0047] Figure 3 and Figure 4 In and

[0047] , the swing of the supporting plate 4 is driven by a micro linear actuator 7. The base of the micro linear actuator 7 is fixed to the bed board 2 through a hinge support 71, and the end of the telescopic rod 72 is hinged to the bottom surface of the supporting plate 4 through a ball joint 73, and its hinge point should be as far away from the rotating shaft 41 as possible.

[0048] The micro linear actuator can adopt any conventional linear driving device, and its structure belongs to the category of existing mature technologies. It can be directly selected from commercially available standard parts according to actual needs, and the internal structure of the present invention will not be elaborated.

[0049] Each of the two supporting plates 4 is connected to a set of micro linear actuators 7 for driving. In this way, not only can the two micro linear actuators on both sides be synchronized in telescopic movement to control the synchronous driving of the two supporting plates, but also it is convenient to control the independent driving of the micro linear actuators on both sides respectively to achieve an independent mode of alternately driving to adjust the left and right positions of the head.

[0050] As Figure 2 and Figure 3 shown, directly above the receiving hole 3 and corresponding to the forehead area, a second receiving groove 32 is also provided, and a swingable second supporting plate 6 is arranged therein, and it is driven by an independently arranged micro linear actuator 7 with the same structure. By the upward swing of the second supporting plate 6, the height of the human head is elevated. The swing angle of the second supporting plate 6 is limited to 0° to 15°.

[0051] The supporting plate 4 and the bed board 2 are integrally coated with a flexible wrapping material, and the flexible wrapping material is not shown in the figure.

[0052] Embodiment 2

[0053] The structure of the neck and shoulder acupuncture treatment bed based on the prone position is also as shown in Embodiment 1 Figure 1 shown, including a bracket 1, a bed board 2 fixedly installed thereon, a receiving hole 3 opened in the head area of the bed board 2, a receiving groove 31 and a second receiving groove 32 provided on the edge of the receiving hole 3, and a supporting plate 4 and a second supporting plate 6 respectively arranged in the receiving groove 31 and the second receiving groove 32 and adapted to the groove shapes thereof.

[0054] As Figure 5As shown in the figure, a support frame 8 is provided below the bed board 2. The setting of the support frame 8 will not affect or block the view of the supporting holes 3 on the bed board 2, and load-bearing supports 5 are fixedly installed on the support frame 8 at positions corresponding to the supporting plate 4 and the second supporting plate 6 respectively.

[0055] Taking the supporting plate 4 as an example, the installation and driving method of the second supporting plate 6 are the same as that of the supporting plate 4.

[0056] As Figure 6 and Figure 7 shown, Figure 7 For Figure 6 structural disassembly, so as to more clearly see the connection relationship of each component. Support frames 42 are fixedly connected to both sides of the supporting plate 4. A limiting arc-shaped guide groove 43 is opened on one side of the center line of the support frame 42, and the central angle of the limiting arc-shaped guide groove 43 is limited to 10°.

[0057] The load-bearing support 5 provided on the support frame 8 is adapted to the above-mentioned support frame 42. A fixed pivot pin 51 is provided on the side wall of the load-bearing support 5, and an oil-impregnated bearing 501 is press-fitted on the pivot pin 51. The pivot pin 51 is inserted into the limiting arc-shaped guide groove 43 on the support frame 42, and the outer diameter of the oil-impregnated bearing 501 is in clearance fit with the limiting arc-shaped guide groove 43 to form a swing pair, so that the supporting plate 4 makes a micro-amplitude elevation angle adjustment around the pivot pin axis to adjust the position of the human head.

[0058] The swing of the supporting plate 4 is also driven by the micro linear actuator 7. The base of the micro linear actuator 7 is fixed to the load-bearing support 5 through a hinge support 71, and the end of its telescopic rod 72 is hinged to the bottom surface of the supporting plate 4 on the side far from the limiting arc-shaped guide groove 43 through a ball joint 73 to form a lever-type moment action. The swing of the supporting plate 4 is restricted by the central angle of the limiting arc-shaped guide groove 43 and can only form a swing angle of 0° to 10°.

[0059] The other structural designs of the acupuncture treatment bed are the same as those in Embodiment 1 and will not be elaborated here.

[0060] The above embodiments of the present invention do not describe all the details in detail, nor do they limit the present invention to only the above-mentioned embodiments. Various changes, modifications, substitutions and variations made by those of ordinary skill in the art to these embodiments without departing from the principle and purpose of the present invention shall be included within the protection scope of the present invention.
