Description

Technical Field

[0001] The present application relates to the technical field of acupuncture and massage nursing, and in particular to a back protection device based on acupuncture and massage nursing. Background Art

[0002] Acupuncture and massage, as time-honored and highly effective treatment methods in Traditional Chinese Medicine, are widely used in the prevention, treatment, and rehabilitation of various diseases. However, in current acupuncture and massage nursing practices, the design of the nursing beds used often focuses on basic support and comfort, but lacks significant protection for user safety, particularly regarding the stability of the needles during the procedure.

[0003] Existing acupuncture and massage nursing beds generally lack effective protective devices for the user's back, the primary area of ​​acupuncture treatment. During acupuncture treatment, silver needles are precisely inserted into specific acupuncture points on the body to exert their therapeutic effects. However, once the needles are fixed in the patient's body, their stability becomes a critical factor affecting treatment effectiveness and patient safety. Current nursing bed designs fail to fully account for this. As a result, if the patient's back is accidentally impacted or squeezed by external forces while receiving massage or other forms of auxiliary treatment, the silver needles may be forced deeper into the body due to external forces, causing pain, bleeding, or even more serious medical accidents, seriously threatening the patient's life, health, and safety.

[0004] Therefore, the present application provides a back protection device based on acupuncture and massage care to solve the above problems. Summary of the Invention

[0005] The present application provides a back protection device based on acupuncture and massage care, which aims to solve the problem raised in the background art that after the silver needles are inserted into the back of the user, if the back is accidentally hit or squeezed by external force, the silver needles may continue to penetrate into the body due to the external force, thereby causing pain, bleeding and even more serious medical accidents, seriously threatening the patient's life, health and safety.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a back protection device based on acupuncture and massage care, comprising a bed board, a mattress arranged on the bed board, and corresponding through grooves provided on the bed board and the mattress; To prevent the silver needles on the user's back from being impacted by external forces and potentially moving further into the user's body, a protective structure is installed on the end of the mattress away from the bedplate. This structure comprises a fixed guard plate on the mattress end away from the through-slot, a movable guard plate hinged to the fixed guard plate at the end near the through-slot, and support plates symmetrically located on either side of the bedplate and connected to the fixed guard plate. The bottom ends of the movable guard plates are equipped with storage slots. Before the acupuncture and massage treatment begins, the therapist first folds the movable guard plate over the top of the fixed guard plate, using the storage slots to store necessary items. The silver needles are then precisely inserted into the acupuncture points on the user's back according to the treatment requirements. At the end of the treatment, or when additional back protection is needed, the movable guard plate is unfolded parallel to the fixed guard plate, forming a complete protective barrier. In this position, even if subjected to external impact, the protective structure effectively blocks and distributes the force, protecting the silver needles on the user's back. The protective structure not only protects the user's back but also serves as a nursing table.

[0007] Preferably, in order to improve the stability of the movable guard plate in the deployed state, especially at the end thereof away from the fixed guard plate: reinforcing rib mechanisms for auxiliary support of the movable guard plate are provided on both sides of the fixed guard plate, and the reinforcing rib mechanisms include a fixed plate fixedly provided at one end of the fixed guard plate close to the movable guard plate, a hinge plate hinged to the fixed plate, limiting grooves symmetrically provided at the end of the movable guard plate away from the fixed guard plate, and a limiting slide bar provided inside the limiting groove and connected to the end of the hinge plate away from the fixed plate. The introduction of the reinforcing rib mechanism significantly improves the stability of the movable guard plate in the deployed state, effectively prevents shaking or tilting due to external forces, and thus better protects the back safety of the user.

[0008] Preferably, to reduce wear between the limiting slide bar and the limiting slot, a bearing is provided between the limiting slide bar and the limiting slot. The introduction of the bearing significantly reduces frictional resistance between the limiting slide bar and the limiting slot, making the deployment and locking of the movable guard plate smoother and more unobstructed. By reducing friction and wear, the bearing effectively extends the service life of the limiting slide bar, the limiting slot, and the entire protective structure.

[0009] Preferably, to facilitate locking the position between the fixed plate and the hinged plate after adjustment, a traction spring is provided between the hinged rod of the fixed plate and the position-limiting slide bar. The traction spring is initially in a stretched and force-accumulating state. The presence of the traction spring increases the connection strength between the fixed plate and the hinged plate, maintaining a stable connection between the two plates even under vibration or external forces, preventing accidental loosening or displacement.

[0010] Preferably, to facilitate supporting the movable guard plate after rotation and folding, and to maintain the movable guard plate in a horizontal position, support pads are symmetrically disposed on the end of the fixed guard plate away from the mattress to support the movable guard plate when folded. The support pads are located away from the end of the movable guard plate. The addition of the support pads effectively prevents the movable guard plate from sagging or tilting due to gravity after rotation and folding, ensuring the stability and safety of the entire structure.

[0011] Preferably, to facilitate adjustment of the protective structure's position, guide rails are fixedly mounted on both sides of the bed plate. Sliders are slidably mounted on the guide rails, connected to the support plate, and used to move the protective structure toward or away from the through-slot. The design of the guide rails and sliders allows for flexible and quick adjustment of the protective structure's position, allowing users to adjust its position at any time based on actual usage. The fixed installation of the guide rails and the sliding design of the sliders ensure the stability of the protective structure during movement, preventing shaking or drifting.

[0012] Preferably, to facilitate height adjustment of the protective structure and adapt it to different user groups, the bed board is provided with a lifting mechanism for adjusting the height of the protective structure. The lifting mechanism comprises a support sleeve mounted on the end of the support board near the mattress, a single-sided tooth groove formed in the support board, a gear meshed in the single-sided tooth groove and rotatably connected to the support sleeve for driving the support board to move and raise or lower the support board, and a driver mounted on the support sleeve for rotating the gear. The support sleeve is fixedly mounted on the slider. When a user wishes to adjust the height of the protective structure, they first operate the driver to rotate the gear. As the gear rotates, its teeth gradually move along the tooth surface of the single-sided tooth groove. Because the single-sided tooth groove is formed in the support board and tightly meshes with the gear, the rotation of the gear drives the support board to rise and fall vertically. Furthermore, because the support sleeve is fixedly mounted on the slider and mounted on the end of the support board near the mattress, the lifting and lowering movement of the support board is guided and restricted by the support sleeve, ensuring stability and accuracy of the lifting process. In this way, the user can easily and precisely adjust the height of the protective structure.

[0013] Preferably, the drive member includes a drive rod rotatably connected to the bottom of the support sleeve, a sprocket mounted on the drive rod and the gear shaft, and a chain belt meshingly mounted on the two sprockets. The transmission mechanism of the sprocket and chain belt has a high transmission efficiency and can effectively transmit the rotational power input by the user to the gear, thereby driving the protective structure to rise and fall. The closed-loop design of the chain belt makes the transmission process more stable and reliable, avoiding transmission failure caused by loosening or falling of the transmission parts. At the same time, the meshing between the sprocket and chain belt also enhances the stability of the transmission.

[0014] Preferably, a worm gear combiner is fixedly mounted on the support sleeve, the worm on the worm gear combiner is fixedly sleeved on the drive rod, and the bottom of the worm on the worm gear combiner is fixedly connected to a handwheel. The worm gear combiner realizes the effective conversion and transmission of driving force through the engagement of the worm wheel and the worm, thereby improving the transmission efficiency. The user can adjust the height of the protective structure simply by rotating the handwheel, without the need for complicated operating steps or tool assistance. The self-locking feature of the worm gear combiner ensures the stability of the protective structure when it is not affected by external forces. This self-locking property not only improves the safety of use, but also avoids the problem of lifting failure due to unexpected circumstances.

[0015] Preferably, in order to prevent the user's back from suddenly lifting up, causing the silver needles on the user's back to collide with the movable guard plate, causing the silver needles to continue to move into the user's body and cause harm to the user: the bottom of the movable guard plate away from the fixed guard plate is symmetrically fixedly connected with an elastic column for contacting the user's back. The design of the elastic column effectively prevents hard collisions between the user's back and the treatment device, thereby avoiding potential risks such as movement of the silver needle position or increase in depth due to collisions, and improving the safety of the treatment process. Since the elastic column has a certain degree of compressibility and resilience, it can adapt to users of different body shapes and postures.

[0016] This application effectively prevents the risk of needles penetrating deeply into the patient's body due to external forces by combining a fixed and movable guard plates, thus ensuring the safety of the treatment process. When the movable guard plate is folded onto the fixed guard plate, it can be used as a nursing table, making it convenient to place items used for acupuncture, massage, and nursing care on the movable guard plate, thus improving the versatility of the protective structure.

[0017] The design of the lifting mechanism in this application allows the height of the protective structure to be flexibly adjusted to meet the needs of different groups, improving the versatility and adaptability of the product. Users can adjust the height of the protective structure simply by operating the drive member, without the need for complex operation steps or tools, greatly improving the convenience of use.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0021] Example 1 This embodiment provides a back protection device based on acupuncture and massage care, such as Figure 1-7 As shown, the protective device includes a bed board 1, a mattress 2 arranged on the bed board 1, and through grooves 3 correspondingly opened on the bed board 1 and the mattress 2; To prevent the needles on the patient's back from being impacted by external forces and potentially moving further into the patient's body, a protective structure 4 is installed on the end of the mattress 2 away from the bed board 1. This structure comprises a fixed guard plate 41 on the end of the mattress 2 away from the through-slot 3, a movable guard plate 42 hinged to the fixed guard plate 41 at the end near the through-slot 3, and support plates 43 symmetrically arranged on either side of the bed board 1 and connected to the fixed guard plate 41. The bottom end of the movable guard plate 42 features a storage slot 421. The combination of the fixed guard plate 41 and the movable guard plate 42 effectively prevents the needles from penetrating deeper into the patient's body due to external forces, ensuring the safety of the treatment process. The foldable and deployable design of the movable guard plate 42 saves space when the bed is not in use. The built-in storage slot 421 also fully utilizes space, reducing the need for an additional nursing table. The storage slot 421 allows therapists to easily access treatment items, improving work efficiency and the smoothness of the treatment process. Before the acupuncture and massage treatment begins, the therapist first folds the movable guard plate 42 on top of the fixed guard plate 41 and uses the storage slot 421 to store the necessary items. Subsequently, the silver needles are precisely inserted into the acupuncture points on the back of the user according to the treatment requirements. When the treatment is over or when additional protection is needed for the user's back, the movable guard plate 42 is unfolded to a position parallel to the fixed guard plate 41 to form a complete protective barrier. In this state, even if subjected to external impact, the protective structure 4 can effectively block and disperse the force, protecting the silver needles on the user's back from being affected. The folded movable guard plate 42 and the fixed guard plate 41 can save space occupied by the protective structure 4. At the same time, the folded movable guard plate 42 and the fixed guard plate 41 can also be used as a nursing table, reducing the need for additional nursing tables in traditional practice and further reducing space occupancy. The unfolded movable guard plate 42 and the fixed guard plate 41 form a protective barrier. When subjected to external force collision, the fixed guard plate 41 and the movable guard plate 42 can block the collision and then protect the user's back.

[0022] Specifically, in order to improve the stability of the movable guard plate 42 in the unfolded state, especially at the end thereof away from the fixed guard plate 41: a reinforcing rib mechanism 5 for auxiliary support of the movable guard plate 42 is provided on both sides of the fixed guard plate 41. The reinforcing rib mechanism 5 includes a fixed plate 51 fixedly provided at one end of the fixed guard plate 41 close to the movable guard plate 42, a hinged plate 52 hinged on the fixed plate 51, a limiting groove 53 symmetrically provided on the end of the movable guard plate 42 away from the fixed guard plate 41, and a limiting slide 54 provided inside the limiting groove 53 and connected to the end of the hinged plate 52 away from the fixed plate 51. The introduction of the reinforcing rib mechanism 5 significantly improves the stability of the movable guard plate 42 in the unfolded state, effectively preventing shaking or tilting caused by external forces, thereby better protecting the back safety of the user. Before the acupuncture and massage treatment begins, the movable guard plate 42 is in a folded state. At this time, the hinged plate 52 of the reinforcing rib mechanism 5 remains relatively still with respect to the fixed plate 51 and does not participate in the supporting function. When the therapist unfolds the movable guard plate 42 to be parallel to the fixed guard plate 41, as the movable guard plate 42 moves, the limiting slide 54 gradually moves along the inside of the limiting groove 53 toward one end close to the fixed guard plate 41. When the movable guard plate 42 reaches the predetermined position, the limiting slide 54 moves to the side of the inside of the limiting groove 53 and fits tightly together, forming a stable limiting structure with the hinge plate 52. At this time, the reinforcing rib mechanism 5 begins to play a role. Through the coordinated action of the fixed plate 51, the hinge plate 52, the limiting groove 53 and the limiting slide 54, additional support force is provided to the movable guard plate 42, thereby enhancing its overall stability. During the entire treatment process, no matter how the user moves or what kind of external force is applied, the protective structure 4 can remain stable and not deformed, ensuring the safe conduct of acupuncture treatment.

[0023] More specifically, to reduce wear between the limiting slide 54 and the limiting groove 53, a bearing 541 is interposed between the limiting slide 54 and the limiting groove 53. The introduction of the bearing 541 significantly reduces frictional resistance between the limiting slide 54 and the limiting groove 53, making the deployment and locking of the movable guard plate 42 smoother and more seamless. By reducing frictional wear, the bearing 541 effectively extends the service life of the limiting slide 54, the limiting groove 53, and the entire protective structure 4. Before or during acupuncture and massage treatment, when the movable guard plate 42 needs to be deployed to provide back protection, the therapist simply pushes the movable guard plate 42 gently. At this point, the limiting slide 54 begins to slide along the limiting groove 53 with the assistance of the bearing 541. Due to the rolling friction characteristics of the bearing 541, the entire sliding process becomes very smooth and has low resistance. When the movable guard plate 42 is fully deployed and parallel to the fixed guard plate 41, the limiting slide 54 slides neatly into the end of the limiting groove 53 and is locked. At this time, the bearing 541 continues to play its role in reducing friction and wear, ensuring that the entire protective structure 4 remains stable and reliable during long-term use.

[0024] Furthermore, to facilitate locking the position between the fixed plate 51 and the hinged plate 52 after adjustment, a traction spring 6 is interposed between the hinged rod of the fixed plate 51 and the limiting slide 54. Initially in a stretched and charged state, the traction spring 6 strengthens the connection between the fixed plate 51 and the hinged plate 52, maintaining a stable connection even under vibration or external forces, preventing accidental loosening or displacement. When the movable guard plate 42 is in the expanded or folded state, the elastic force of the traction spring 6 locks the hinged plate 52 in place, ensuring that the movable guard plate 42 remains stable during the expansion or folding process.

[0025] Specifically, to support the movable guard plate 42 after rotation and folding, and to maintain its horizontal position, support pads 7 are symmetrically positioned on the end of the fixed guard plate 41 facing away from the mattress 2. These pads are positioned symmetrically on the end of the fixed guard plate 41 facing away from the mattress 2 to ensure perfect alignment and effective support for the movable guard plate 42 after rotation and folding. The shape, size, and material of the support pads 7 are customized to meet specific needs, ensuring sufficient support while balancing ease of use and comfort. The support pads 7 are made of rubber. The addition of the support pads 7 effectively prevents the movable guard plate 42 from sagging or tilting due to gravity after rotation and folding, ensuring the stability and safety of the entire structure. As the movable guard plate 42 rotates and folds around the fixed guard plate 41, its bottom edge gradually approaches and contacts the support pads 7. As rotation continues, the weight of the movable guard plate 42 gradually transfers to the support pads 7 until it is fully folded and horizontal. At this time, the support pad 7 provides a stable support force for the movable guard plate 42 to ensure that it will not sag or tilt due to gravity. During the whole process, the user only needs to easily rotate the movable guard plate 42 to complete the adjustment without the need for additional auxiliary tools or operations.

[0026] Specifically, to facilitate adjustment of the position of the protective structure 4: guide rails 8 are fixedly installed on both sides of the bed board 1, and a slider 81 is slidably provided on the guide rails 8, which is connected to the support plate 43 and is used to drive the protective structure 4 to move closer to or away from the through slot 3. The design of the guide rails 8 and the slider 81 makes the position adjustment of the protective structure 4 flexible and quick, and the user can adjust its position at any time according to actual usage. The fixed installation of the guide rails 8 and the sliding design of the slider 81 ensure the stability of the protective structure 4 during movement, avoiding the occurrence of shaking or offset. When the user needs to adjust the position of the protective structure 4, he only needs to apply a push or pull force to the slider 81 through the control device. Under the action of the push or pull force, the slider 81 slides along the guide direction of the guide rail 8. Since the slider 81 is connected to the support plate 43, the entire protective structure 4 will also move synchronously with the movement of the slider 81. In this way, the user can easily adjust the protective structure 4 to the desired position, moving it closer to or away from the through slot 3 to meet different usage requirements.

[0027] Furthermore, to prevent the user's back from suddenly lifting up, causing the silver needles on the user's back to collide with the movable guard plate 42, causing the silver needles to continue moving into the user's body and causing injury to the user, elastic columns 422 are symmetrically fixedly connected to the bottom of the movable guard plate 42 away from the fixed guard plate 41, which are used to contact the user's back. Among them, the elastic columns 422 are made of highly elastic and low-compression permanent deformation materials, such as high-quality silicone, high-elasticity sponge or memory foam. These materials not only have good resilience and cushioning properties, but also can effectively disperse impact forces and reduce the impact on the user's back. The elastic columns 422 are designed in a cylindrical or hemispherical shape, with a flat bottom and firmly connected to the movable guard plate 42. The elastic columns 422 are symmetrically arranged at the bottom of the movable guard plate 42 away from the fixed guard plate 41, and the number is determined by the width and length of the movable guard plate 42. This layout can not only ensure uniform support for the entire back area, but also effectively disperse impact forces and improve the protective effect. The design of elastic column 422 effectively prevents hard impact between the user's back and the treatment device, thereby avoiding potential risks such as needle displacement or increased insertion depth due to impact, and improving the safety of the treatment process. Because elastic column 422 has a certain degree of compressibility and resilience, it can adapt to users of different body shapes and postures.

[0028] Example 2 Unlike Example 1, (the issue of the protective structure 4 being too close to the user's back may arise depending on the user's usage) a lifting mechanism 9 is provided on the bed board 1 for adjusting the height of the protective structure 4. This lifting mechanism 9 comprises a support sleeve 91 mounted on the end of the support plate 43 near the mattress 2, a single-sided tooth groove 92 formed in the support plate 43, a gear 93 engaged in the single-sided tooth groove 92 and rotatably connected to the support sleeve 91 for driving the support plate 43 to move up and down, and a drive member 94 mounted on the support sleeve 91 for rotating the gear 93. The support sleeve 91 is fixedly mounted on the slider 81. The gear 93 is designed to tightly engage with the single-sided tooth groove 92 and rotates through the rotational connection with the support sleeve 91. As the gear 93 rotates, its teeth move along the tooth surface of the single-sided tooth groove 92, thereby driving the support plate 43 to rise and fall vertically. The design of the lifting mechanism 9 allows the height of the protective structure 4 to be flexibly adjusted to meet the needs of different groups, improving the product's versatility and adaptability. The user can adjust the height of the protective structure 4 simply by operating the actuator 94, eliminating the need for complex steps or tools, greatly improving ease of use. The tight meshing of the unilateral tooth groove 92 and the gear 93, along with the secure mounting of the support sleeve 91, ensures stability and load-bearing capacity during the lifting process, preventing wobbling or drifting. To adjust the height of the protective structure 4, the user first operates the actuator 94 to rotate the gear 93. As the gear 93 rotates, its teeth gradually move along the tooth surface of the unilateral tooth groove 92. Because the unilateral tooth groove 92 is defined on the support plate 43 and tightly meshes with the gear 93, the rotation of the gear 93 drives the support plate 43 vertically upward and downward. Furthermore, because the support sleeve 91 is fixedly mounted on the slider 81 and fits over the end of the support plate 43 near the mattress 2, the lifting and lowering movement of the support plate 43 is guided and restricted by the support sleeve 91, ensuring stability and accuracy during the lifting process. In this way, the user can easily and precisely adjust the height of the protective structure 4. (In this embodiment, when the gear 93 rotates clockwise, the protective structure 4 descends; when the gear 93 rotates counterclockwise, the protective structure 4 ascends) Furthermore, the driving member 94 includes a driving rod 941 that is rotatably connected to the bottom of the support sleeve 91, a sprocket 942 that is mounted on the driving rod 941 and the shaft of the gear 93, and a chain belt 943 that is meshed and mounted on the two sprockets 942. The sprockets 942 are mounted on the shafts of the driving rod 941 and the gear 93. Specifically, one sprocket 942 is fixedly connected to the bottom of the driving rod 941, while the other sprocket 942 is fixedly connected to the shaft of the gear 93. In this way, when the driving rod 941 rotates, the sprocket 942 connected thereto also rotates. The chain belt 943 is meshed and mounted on the two sprockets 942, forming a closed-loop transmission chain, ensuring the smoothness and accuracy of the transmission. The transmission mechanism of the sprocket 942 and the chain belt 943 has a high transmission efficiency and can effectively transmit the rotational power input by the user to the gear 93, thereby driving the protective structure 4 to rise and fall. The closed-loop design of chain belt 943 ensures a more stable and reliable transmission process, preventing transmission failures caused by loose or falling transmission components. Furthermore, the meshing between sprocket 942 and chain belt 943 enhances transmission stability. To adjust the height of protective structure 4, the user first inputs rotational power by rotating drive rod 941. The rotation of drive rod 941 drives the connected sprocket 942 to rotate as well. Because chain belt 943 is meshed and sheathed around two sprockets 942, when one sprocket 942 rotates, it moves with it, driving the other sprocket 942 to rotate in the same direction. This also drives the sprocket 942 connected to the shaft of gear 93 to rotate. Ultimately, the rotation of gear 93 drives the support plate 43 to move vertically upward and downward, thereby adjusting the height of protective structure 4. Throughout the entire transmission process, the tight meshing between sprocket 942 and chain belt 943 ensures smooth and accurate transmission.

[0029] Furthermore, a worm gear assembly 10 is fixedly mounted on the support sleeve 91. The worm wheel on the worm gear assembly 10 is fixedly mounted on the drive rod 941, and a handwheel 101 is fixedly connected to the bottom of the worm on the worm gear assembly 10. The worm wheel is fixedly mounted on the drive rod 941, forming an integral structure with the drive rod 941. When the drive rod 941 rotates, the worm wheel also rotates. The worm is another key component in the worm gear assembly 10, and the handwheel 101 is fixedly connected to the bottom of the worm. The user can rotate the worm by rotating the handwheel 101. The worm wheel and worm achieve transmission through a precise meshing relationship. This meshing relationship is self-locking. That is, when the worm stops rotating, the worm wheel and the drive rod 941 also remain stationary, preventing the protective structure 4 from automatically raising or lowering without external forces. The worm gear assembly 10 achieves effective conversion and transmission of driving force through the meshing of the worm wheel and worm, thereby improving transmission efficiency. The user can adjust the height of the protective structure 4 simply by rotating the handwheel 101, without the need for complex steps or tools. The self-locking feature of the worm gear assembly 10 ensures the stability of the protective structure 4 when not subjected to external forces. This self-locking feature not only improves safety but also prevents the lifting mechanism from failing due to unexpected circumstances. When the user needs to adjust the height of the protective structure 4, they first rotate the handwheel 101 to rotate the worm. The rotation of the worm drives the meshing worm wheel to rotate as well. Because the worm wheel is fixedly mounted on the drive rod 941, the rotation of the worm wheel drives the drive rod 941. The rotation of the drive rod 941 is then transmitted to the gear 93 via the transmission mechanism of the sprocket 942 and chain belt 943, ultimately driving the support plate 43 to move vertically. Throughout the entire transmission process, the self-locking feature of the worm gear assembly 10 ensures transmission stability and reliability. Furthermore, the user can adjust the height of the protective structure 4 at any time by rotating the handwheel 101 to meet the needs of different usage scenarios.
