Technical Field

[0001] This utility model belongs to the field of acupuncture instruments, and in particular relates to a trunk support device for an acupuncture massage bed. Background Technology

[0002] As people's living standards improve, their health awareness continues to increase. They have shifted from treating only what feels uncomfortable to treating what prevents illness, paying more attention to health therapy to regulate their physical condition.

[0003] Acupuncture is a traditional Chinese medicine therapy that often requires patients to lie prone on a bed for extended periods in a static posture to expose the treatment area. This static posture effectively prevents the needles from bending. To improve patient comfort, modern therapy beds typically have openings for the face, allowing patients to place their face over these openings for unobstructed breathing. However, this prolonged posture, combined with the fact that traditional therapy beds are usually flat, can still compress the lungs, causing breathing difficulties and potentially leading to lower back discomfort. To address these issues, Chinese patent CN118697637A discloses an acupuncture and massage therapy device. This device uses a split-type reclining board to support different parts of the body and provides a range of comfort adjustments via a reclining cushion. However, its structure is complex and lacks flexibility. Summary of the Invention

[0026] Example 1

[0027] like Figures 1-4 As shown, a trunk support device for an acupuncture and massage bed is mounted on the bed frame and includes a shoulder mechanism, a chest mechanism, and an abdominal and hip mechanism.

[0028] The shoulder mechanism includes a first slide rod 11, a sliding seat 12, and a shoulder positioning mold 13. The sliding seat 12 is slidably connected to the first slide rod 11, and the shoulder positioning mold 13 is mounted on the sliding seat 12. The shoulder positioning mold 13 has a shallow recess in the middle to align and accommodate the user's humeral head, thereby positioning both shoulders. The shoulder positioning mold 13 has a smooth transition structure on its upper and outer sides to facilitate arm movement in the horizontal plane when prone. The shoulder positioning mold has a slightly upward-protruding arc-shaped overhang on the front side, which is used to limit the humeral head of the shoulder from the front to ensure that the humeral head is located in the shallow fossa. The above is the shoulder positioning mold of this embodiment. It can also be any model of the prior art, as long as it can accommodate the humeral head of the shoulder, such as a shallow groove disc. The two ends of the first slide rod 11 are provided with concave steel parts 14. The concave opening of the concave steel part 14 faces the inner side of the bed beam. The concave opening of the concave steel part 14 matches the height of the bed beam. The concave steel part 14 is fixed to the bed beam by positioning pins, so that the shoulder mechanism is inserted into the bed beam. Since it is necessary to ensure the horizontal movement of the shoulder positioning mold 13, limit grooves are symmetrically opened along the axis on the first slide rod 11. The inner ring of the sliding seat is correspondingly provided with protrusions, so that the sliding seat can move on the first slide rod. It is preferable to provide two pairs of limit grooves.

[0029] The main function of the shoulder mechanism is to match the shoulder width of users with different body types, thereby initially positioning the patient in bed and driving subsequent related mechanisms to perform adaptive movements.

[0030] The thoracic mechanism includes a first link 21, a second link 22, and a thoracic spine support mechanism. The front ends of the first and second links are fixedly connected to the sliding seat 12. The thoracic spine support mechanism includes a thoracic spine support body 23, a lifting electric actuator 24, a rotary motor 25, and a support belt 26. The thoracic spine support body 23 is a cuboid with several openings evenly spaced on both sides, and the openings on the left and right sides are staggered. The rotary motor 25 is fixedly connected to the rear end of the thoracic spine support body, and the rotating shaft of the rotary motor 25 extends into the cube. The front end of the rotary motor 25 is connected to the front end face of the thoracic spine support body by a bearing. This is used to connect to the front end of the rotating motor shaft. In this embodiment, the rotating motor is located inside the rear end of the thoracic spine support, which can effectively reduce the possible impact of the rotating motor on the patient. The support belt 26 includes several support plates 261 and elastic bands 262. Elastic band fixing grooves 262 are opened on both sides of the support plates 261. Adjacent support plates are connected by elastic bands to form a support system with a certain elasticity, which is conducive to adapting to changes in the chest cavity caused by breathing and reducing the pressure on the chest cavity when prone. One end of the support belt 26 is fixedly connected to the rotating shaft, and the other end extends out through an opening. When connecting to the corresponding first and second connecting rods, it is important to note that a flexible connection is preferred for the connection between the support belt 26 and the rotary motor shaft. This facilitates the initial winding of the support belt onto the shaft. Simultaneously, the opening sizes on both sides of the thoracic spine support body are matched to the support belt. However, to ensure the stability of the equipment, several partitions 231 are installed inside the thoracic spine support body perpendicular to the axis of the rotary motor shaft. The lower side of each partition has an elongated hole to accommodate the rotary motor shaft, facilitating partition installation. The partitions 231 are correspondingly positioned on the front and rear sides of the support belt 26 to form a support belt... The guide groove is formed to prevent it from deviating when it rotates on the shaft; the lifting electric push rod 24 is set at the bottom of the bed frame, and the front end of the electric push rod 24 is fixedly connected to the bottom of the thoracic spine support body 23. It is used to adapt to the height of the chest cavity and solve the problem of compression of the chest cavity when people lie prone on a traditional horizontal bed board. Appropriate lowering can reduce the force on the chest cavity. At the same time, with the support of the abdominal and hip mechanism of this application, it can effectively solve the problem of breathing difficulties caused by prolonged prone lying. It can also prevent the problem of uneven back caused by traditional use of pillows to adjust prone posture, and is more conducive to acupuncture treatment.

[0031] The pelvic support mechanism includes a pelvic support plate 3 and an abdominal support belt 4. The pelvic support plate 3 is a flat plate with bent plates vertically installed at both ends for attaching to the bed beam. The pelvic support plate 3 corresponds to the patient's pelvis and can move on the bed beam. After being moved to the appropriate position, it is positioned by a pin. Therefore, several corresponding pin holes are provided on the outer side of the bed beam. A second sliding rod 31 is provided at the front end of the flat plate, and the rear ends of the first and second connecting rods are slidably connected to the second sliding rod. The abdominal support belt 4 is a flexible belt, made of cowhide in this embodiment, with a belt width of 25-35 cm. It is adjustable and fixed on the bed beam, located between the chest mechanism and the pelvic support plate. The abdominal support belt 4 has Velcro hard surfaces at both ends, and the corresponding rough surfaces of the Velcro are provided on the outer side of the bed beam. When the patient is lying down, the staff can adjust the tension of the abdominal support belt through the Velcro, which, together with other components, forms effective support for the abdomen.

[0032] In this embodiment, latex pads are provided on the upper surfaces of the thoracic spine support, the support plate of the support belt, the hip support plate, and the shoulder positioning mold, which can make the patient more comfortable. In particular, considering the shape of the thoracic spine, the front end of the latex pad on the upper surface of the thoracic spine support is higher than the rear end, which can better form a support effect. It is recommended to lay a sheet on the outside of the device during use to help protect the equipment.

[0033] It also includes a control system, including a microcontroller control board, an operating console, and a pressure sensor. The pressure sensor is installed between the thoracic spine support and the rubber pad to sense the pressure of the human body. The microcontroller control board is connected to the operating console, the pressure sensor, the lifting electric actuator, and the rotary motor circuitry. It is used to control the lifting electric actuator and the rotary motor based on the feedback from the pressure sensor, and the rotary motor can be manually controlled through the operating console.

[0034] In use, the device is in its initial state, with the thoracic spine support, hip support plate, and abdominal support belt horizontally positioned. The support belt has a reserved length to facilitate adjustment of the shoulder positioning mold. After the patient lies prone, the shoulder positioning mold is moved with the assistance of staff until the humeral head of the patient's shoulder is positioned within it. The shoulder positioning mold has a very shallow, arc-shaped groove, making it easy to locate. High precision is not required for positioning; patient comfort is the priority. Then, staff adjust the position of the hip support plate to align with and fix it to the patient's hip, completing the initial positioning of the patient.

[0035] Then, the control system is activated. The control system reads the pressure sensor data and controls the lifting electric actuator to move the thoracic spine support body according to the system preset value until the pressure meets the preset threshold. This preset value is based on the average value of medical data statistics and can be flexibly adjusted using the control panel according to the patient's feelings, also with the patient's comfort as the standard. Then, the staff adjusts the abdominal support belt, also according to the patient's body shape, to ensure support for the patient's abdomen. Here, the patient's comfort can be taken into account, but sufficient support must be ensured. Finally, the control console controls the rotary motor to adjust the support belt to assist in forming support for the chest cavity, with the patient's comfort as the standard.

[0036] After the above adjustments, the patient can comfortably lie prone on the bed, with the shoulders and hips serving as the overall positioning, ensuring the main support for the torso. At the same time, the abdominal support belt and chest mechanism provide personalized support for the torso. The chest mechanism mainly addresses the issue of compression of the chest cavity as a high point when lying prone, which can cause difficulty in exhalation over time. It can also cause changes in the force on the lower back due to chest support, leading to lower back fatigue. By adjusting the thoracic spine support, chest cavity compression is reduced when lying prone, and the changes in the force on the lower back caused by chest support are also reduced. Then, the personalized adjustment of the abdominal support belt to the lower back and abdomen provides effective support, making the patient more comfortable when lying prone and reducing discomfort when the patient is in a static state after acupuncture, thus avoiding any impact on the acupuncture treatment.

[0037] Example 2

[0038] If, after the application device is placed on the bed, there is no bed board provided to support the arms, or if the bed is too large, a support plate can be fixedly connected to the top of the first and second connecting rods. The support plate extends from the top of the first and second connecting rods toward the outer bed beam and is located on the upper side of the bed beam, mainly for supporting the arms.

[0039] Example 3

[0040] like Figure 5 As shown, a push plate 5 is horizontally installed at the front end of the lifting electric push rod. Springs 51 are arranged between the push plate 5 and the bottom surface of the thoracic spine support, so that a certain elastic buffer is formed between the thoracic spine support and the lifting electric push rod. This can further reduce the compression of the chest caused by prolonged prone lying, especially when prone lying for more than 40 minutes.
