Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an automatic bed suitable for Berg motion. Background Technology

[0002] Buerger exercises are a rehabilitation training method that promotes blood circulation in the lower limbs through postural changes. They are primarily used to prevent thrombosis and improve insufficient arterial blood supply, and are suitable for conditions such as lower limb venous thrombosis, diabetic foot, lower limb arteriosclerosis obliterans, and thromboangiitis obliterans. Their standardized operating procedures include: 1. Elevate the legs (to promote venous return): The patient lies flat on the bed with both legs straight and raised to a 45°~60° angle with the bed (pillows or blankets can be used to support the back of the legs), and maintain for 1~2 minutes until the skin of the feet turns pale or slightly numb (indicating that venous blood is returning sufficiently). 2. Leg drop exercise (stimulating arterial perfusion): The patient slowly sits up with both legs hanging naturally over the edge of the bed (avoid dangling in the air; the feet can lightly touch the ground).

[0003] However, most existing hospital beds are simple, ordinary beds. When performing Buerger's exercises, patients need guidance and assistance from medical staff to complete the above-mentioned positional changes. The lack of intelligent assistance functions not only increases the workload of medical staff. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an automatic bed suitable for Berg motion, so as to solve the problems mentioned above in the background art.

[0005] An automatic bed suitable for Berg movement includes a bed frame and a support pad disposed on the top of the bed frame, the support pad including a leg support and a hip support disposed in sequence; The rear of the bed is provided with a support frame via a first telescopic member, and the leg support is provided on the support frame via a second telescopic member. The telescopic movement of the first telescopic member drives the support frame to rotate around a horizontal axis, so that the support frame and the leg support provided thereon can switch between a horizontal state and a leg swing state. The telescopic movement of the second telescopic member drives the leg support to rotate relative to the support frame, so that the leg support can switch between a horizontal state and a leg raised state. The horizontal state refers to the support frame and the leg support being horizontal; the leg-lifting state refers to the support frame being horizontal and the leg support and the hip support forming an angle; and the leg-swinging state refers to the support frame causing the leg support and the hip support to form an angle and the tail area of ​​the bed being hollowed out.

[0006] Compared to existing technologies, the advantages of this application are as follows: Through the coordinated design of the bed frame, support pad, support frame, and dual telescopic components (first and second telescopic components), the core posture switching of the Berg movement (leg raise, leg swing, and horizontal position) can be automatically realized, replacing traditional manual assistance methods and significantly improving training efficiency and standardization. The hollow design of the support frame and the rear of the bed frame (in the leg swing position) allows the patient's legs to hang naturally, simulating the "leg hanging activity" posture in the standard Berg movement, effectively promoting blood circulation in the lower limbs, reducing the workload of medical staff, and avoiding poor training results due to human error.

[0007] Furthermore, one end of the first telescopic member is installed at the bottom of the bed, and the other end of the first telescopic member is connected to the support frame.

[0008] Furthermore, one end of the second telescopic member is mounted on the support frame, and the other end of the second telescopic member is connected to the leg support.

[0009] Furthermore, the first telescopic member and the second telescopic member are independently selected from electric push rods, hydraulic cylinders, or pneumatic cylinders.

[0010] Furthermore, the support pad also includes an upper body support, and a third telescopic member is provided between the upper body support and the bed frame.

[0011] Furthermore, it also includes a control system, which is electrically connected to the first telescopic member and the second telescopic member, and is used to control the coordinated telescopic movement of the first telescopic member, the second telescopic member and the third telescopic member.

[0012] Furthermore, an integral protective bag is fitted over the outside of the support pad to form a wrap-around integrated structure between the upper body support, the hip support, and the leg support.

[0013] Furthermore, a support hole is provided at the rear of the bed, and the support frame can rotate around the horizontal axis within the support hole; In the horizontal state, the first telescopic member is in an extended state so that the support frame is supported in the support hole and its top surface is flush with the top surface of the bed, while the second telescopic member is at a specific length to keep the leg support part horizontal. When the leg is raised, the first telescopic member remains extended to keep the support frame horizontal, and the second telescopic member extends to drive the leg support to rotate upward around the support frame, so that the leg support and the hip support form an angle. When the leg is in the swinging state, the second telescopic member is at a specific length. The first telescopic member retracts and drives the support frame to rotate downward around the horizontal axis, so that the leg support part is kept in the support frame. This causes the leg support part to swing downward as a whole, so that the support hole area forms a hollow leg receiving space. Attached Figure Description

[0019] Please see Figures 1 to 2 The image shows an automatic bed suitable for Berg movement according to an embodiment of the present invention, including a bed body 10 and a support pad 20 disposed on the top of the bed body 10. The support pad 20 includes a leg support part 21 and a hip support part 22 disposed in sequence. The rear of the bed 10 is provided with a support frame 24 via a first telescopic member 23. The leg support 21 is provided on the support frame 24 via a second telescopic member 25. The telescopic movement of the first telescopic member 23 drives the support frame 24 to rotate around a horizontal axis, so that the support frame 24 and the leg support 21 provided thereon can switch between a horizontal state and a leg-swinging state. The telescopic movement of the second telescopic member 25 drives the leg support 21 to rotate relative to the support frame 24, so that the leg support 21 can switch between a horizontal state and a leg-lifting state. The horizontal state refers to the support frame 24 and the leg support 21 both being horizontal; the leg-raising state refers to the support frame 24 being horizontal and the leg support 21 and the hip support 22 forming an angle; and the leg-swing state refers to the support frame 24 causing the leg support 21 and the hip support 22 to form an angle, and the tail area of ​​the bed 10 forming a hollow.

[0020] It is worth noting that through the coordinated design of the bed frame 10, support pad 20, support frame 24, and dual telescopic components (first telescopic component 23 and second telescopic component 25), the core posture switching of the Berg movement (leg raised, leg swing, and horizontal position) can be automatically realized, replacing the traditional manual assistance method and significantly improving training efficiency and standardization. The hollow design of the support frame 24 and the rear of the bed frame 10 (in the leg swing position) allows the patient's legs to hang naturally, simulating the "leg hanging activity" position in the standard Berg movement, effectively promoting blood circulation in the lower limbs, reducing the workload of medical staff, and avoiding poor training results due to human error.

[0021] In this embodiment, the bed frame 10 is welded from high-strength aluminum alloy profiles, and the surface is anodized to ensure structural stability and corrosion resistance. The bed frame 10 is 2000mm long, 900mm wide, and its height is adjustable from 450-600mm (to adapt to different nursing scenarios).

[0022] The support pad 20 has an overall thickness of 100mm and consists of a three-layer structure: the bottom layer is high-density sponge (providing support), the middle layer is memory foam (conforming to the curves of the human body), and the top layer is waterproof and breathable PU leather (easy to clean and disinfect).

[0023] The support pad 20 is divided into three independent zones: Leg support section 21: 600mm in length and the same width as the bed frame 10. It can be embedded with carbon fiber heating elements (temperature controllable range 35-40℃) to promote blood circulation in the lower limbs.

[0024] Hip support section 22: 400mm in length, made of highly elastic sponge to distribute pressure and prevent pressure sores.

[0025] Upper body support 26: 1000mm in length, the angle can be adjusted (0-75°) via the third telescopic component 27 to meet the patient's semi-recumbent position requirements.

[0026] Specifically, one end of the first telescopic member 23 is installed at the bottom of the bed frame 10, and the other end of the first telescopic member 23 is connected to the support frame 24. One end of the second telescopic member 25 is installed on the support frame 24, and the other end of the second telescopic member 25 is connected to the leg support 21.

[0027] More specifically, the first telescopic member 23 and the second telescopic member 25 are independently selected from electric push rods, hydraulic cylinders or pneumatic cylinders.

[0028] Support frame 24: It is made of rectangular steel pipe welded together. Its width is the same as that of the bed 10 and its length is 550mm. Both sides are hinged to the support hole 11 at the tail of the bed 10 through pins to form a horizontal rotation axis.

[0029] The first telescopic component 23 is an electric push rod (model DT1000, thrust 1000N). One end is fixed to the center of the bottom of the bed frame 10 via a U-shaped bracket, and the other end is connected to the center of the bottom surface of the support frame 24 via a ball joint. The electric push rod has a stroke of 300mm and a maximum telescopic speed of 10mm / s.

[0030] The second telescopic component 25 also uses an electric push rod (model DT500, thrust 500N), one end of which is fixed to the inner side of the front end of the support frame 24, and the other end is connected to the bottom surface of the leg support 21 through a joint bearing, driving the leg support 21 to rotate around the front end of the support frame 24.

[0031] It is worth noting that the two ends of the first telescopic component 23 are connected to the bottom of the bed frame 10 and the support frame 24, respectively, enabling precise control of the leg-raising angle (45°~60°) and the leg-hanging angle. This ensures that the patient's position conforms to the standard requirements of the Berg movement, improving the scientific nature and effectiveness of rehabilitation training. The two ends of the second telescopic component 25 are connected to the support frame 24 and the leg support 21, respectively, and can independently drive the leg support 21 to rotate relative to the support frame 24, achieving flexible switching between the "leg-raising state" and the "horizontal state." This modular design not only improves the accuracy of position adjustment but also adapts to the differences in body shape among different patients, enhancing the versatility and comfort of the equipment.

[0032] Please see Figures 3 to 5 As shown, the support pad 20 further includes an upper body support 26, and a third telescopic member 27 is provided between the upper body support 26 and the bed frame 10. The addition of the upper body support 26 and the third telescopic member 27 allows adjustment of the patient's upper body angle, assisting the patient in transitioning from a lying to a sitting position. This coordinates with the movements of the leg support 21, fully simulating the entire process of "raising the legs → leg dangling activity → lying flat to rest" in the Berg exercise, making the training process smoother and more natural, and reducing the difficulty for the patient to adjust their position independently.

[0033] Furthermore, a control system is included, electrically connected to the first telescopic member 23 and the second telescopic member 25, for controlling the coordinated telescopic movements of the first telescopic member 23, the second telescopic member 25, and the third telescopic member 27. The integrated design of the control system enables unified control of the three telescopic members, supports multiple preset training modes (such as standard mode, gentle mode, and custom mode), and allows precise setting of parameters such as angle, duration, and number of cycles. Automated operation reduces reliance on medical personnel, improves training efficiency, and ensures the safety and stability of posture adjustment through a sensor feedback mechanism.

[0034] In this embodiment, the main controller of the control system adopts an STM32F407 microcontroller and is equipped with a 10.1-inch color touch screen (800×480 resolution), which supports touch operation and parameter display.

[0035] Angle sensor (model MPU6050): Installed on the rotation axis of the support frame 24 and the leg support 21, it monitors angle changes in real time with an accuracy of ±0.5°.

[0036] Pressure sensors (model HX711): distributed on the surface of the support pad 20, detect whether the patient's position is correct and the weight distribution, and prevent overload.

[0037] Drive module: L298N motor drive chip, which controls the forward and reverse rotation and speed of the three electric actuators.

[0038] User interface: The main interface displays information such as the current mode (standard / gentle / custom), remaining time, and current angle.

[0039] Mode settings interface: You can adjust the holding time of each position (1-10 minutes), leg raise angle (30-60°), leg swing angle (15-30°), and number of cycles (1-10 times).

[0040] Furthermore, an integral protective bag 28 is fitted over the outer side of the support pad 20, forming a wrap-around integrated structure between the upper body support 26, the hip support 22, and the leg support 21. This protective bag design on the outside of the support pad 20 integrates the upper body support 26, the hip support 22, and the leg support 21, improving overall patient comfort and facilitating cleaning and disinfection, thus reducing the risk of cross-infection.

[0041] Specifically, the rear of the bed body 10 is provided with a support hole 11, and the support frame 24 can rotate around the horizontal axis within the support hole 11; In the horizontal state, the first telescopic member 23 is in an extended state so that the support frame 24 is supported in the support hole 11 and its top surface is flush with the top surface of the bed 10, while the second telescopic member 25 is at a specific length to keep the leg support 21 horizontal. When the leg is raised, the first telescopic member 23 remains extended so that the support frame 24 is in a horizontal state, and the second telescopic member 25 extends to drive the leg support 21 to rotate upward around the support frame 24, so that the leg support 21 and the hip support 22 form an angle. When the leg is in the swinging state, the second telescopic member 25 is at a specific length, and the first telescopic member 23 retracts to drive the support frame 24 to rotate downward around the horizontal axis so that the leg support 21 is kept inside the support frame 24, causing the leg support 21 to swing downward as a whole, so that the area of ​​the support hole 11 forms a hollow leg receiving space.

[0042] In practice, the body position switching procedure is as follows: In a horizontal state: the first telescopic member 23 is fully extended (300mm travel), and the top surface of the support frame 24 is flush with the top surface of the bed frame 10; the second telescopic member 25 is retracted to a specific length (e.g., 150mm), and the leg support 21 remains horizontal.

[0043] Leg raised state: The first telescopic component 23 remains extended, and the second telescopic component 25 gradually extends to 250mm, driving the leg support 21 to rotate upward to a 45° angle with the horizontal plane (adjusted in real time by the angle sensor).

[0044] Leg swing state: The second telescopic component 25 retracts to its initial length, and the leg support 21 falls back to the horizontal; the first telescopic component 23 retracts to 150mm, driving the support frame 24 to rotate downward around the horizontal axis to form a 30° angle with the horizontal plane. At this time, a 500mm×900mm hollow area is formed at the tail of the bed 10, allowing the patient's legs to hang down naturally.

[0045] In summary, the above embodiments of this utility model demonstrate the beneficial effects of the automatic bed suitable for Berg motion. Through the coordinated design of the bed frame 10, support pad 20, support frame 24, and dual telescopic components (first telescopic component 23 and second telescopic component 25), the core posture switching of the Berg movement (leg raise, leg swing, and horizontal position) can be automatically realized, replacing the traditional manual assistance method and significantly improving training efficiency and standardization. The hollow design of the support frame 24 and the rear of the bed frame 10 (in the leg swing position) allows the patient's legs to hang naturally, simulating the "leg hanging activity" position in the standard Berg movement, effectively promoting blood circulation in the lower limbs, reducing the workload of medical staff, and avoiding poor training results due to human operation errors.
