[0028] To make the above-mentioned objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] Embodiment 1

[0030] The present invention provides a medical bed, comprising: a bed frame 1, two side guardrails 13, two guardrail turning buckles, a fixed bed board 2, a first flipping bed board 3, a first driving mechanism 4, a second flipping bed board 5 and a second driving mechanism 6. At both ends of the top of the bed frame 1, a headstock baffle 11 and a footboard baffle 12 are respectively arranged. The headstock baffle 11 and the footboard baffle 12 can provide boundary protection for patients to prevent patients from falling during sleep; the two side guardrails 13 are respectively installed on both sides of the top of the bed frame 1; the guardrail turning buckles are used to limit the side guardrails 13 to the erected state or the stored state. When the side guardrails 13 are erected, they can play a role in protecting the safety of patients and preventing them from rolling down. When the side guardrails 13 are stored through the guardrail turning buckles, it is convenient for patients to get on and off the bed.

[0031] The fixed bed board 2 is fixedly connected to the middle of the top of the bed frame 1 to provide a stable support base for patients;; One end of the first flipping bed board 3 is rotatably connected to the side of the fixed bed board 2 close to the headstock baffle 11 and can be limited to the designed position, enabling patients to adjust to a suitable reclining angle, which helps to improve the comfort of patients. For example, it is convenient for patients to eat, watch, etc.; the fixed end of the first driving mechanism 4 is used to be fixedly connected to the bed frame 1, and the driving end of the first driving mechanism 4 is used to drive the end of the first flipping bed board 3 away from the fixed bed board 2 to flip upward or reset and maintain the flipped position.

[0032] One end of the second flipping bed board 5 is rotatably connected to the side of the fixed bed board 2 close to the footboard baffle 12 and can be limited to the designed position, supporting and limiting the ischial tuberosity part of the reclining patient, which can effectively relieve the pressure on this part of the patient, prevent the reclining patient from sliding down, effectively avoid repeated friction on the patient's body when the sliding phenomenon occurs, avoid the formation of pressure sores at the sacrococcygeal region, and effectively ensure the health and rehabilitation process of the patient; the fixed end of the second driving mechanism 6 is used to be fixedly connected to the bed frame 1, and the driving end of the second driving mechanism 6 is used to drive the end of the second flipping bed board 5 away from the fixed bed board 2 to flip upward or reset and maintain the flipped position.

[0033] In a preferred embodiment, the medical bed further includes a third flipping bed board 7. One end of the third flipping bed board 7 is rotatably connected to the end of the second flipping bed board 5 away from the fixed bed board 2, and the other end is slidably connected to the bed frame 1. The setting of the third flipping bed board 7 further enriches the adjustment function of the medical bed and can adapt to the bending of the calf. Its rotational connection with the second flipping bed board 5 and sliding connection with the bed frame 1 can flexibly adjust the bed position according to different postural requirements and physical conditions of patients, enabling patients to obtain a more suitable support and lying experience.

[0034] In a preferred embodiment, the first driving mechanism 4 includes a first crank 41, a first guiding cylinder 42, a first driving rod 43 and a first connecting diagonal rod 44. One end of the first connecting diagonal rod 44 is fixedly connected to the first flipping bedplate 3, and the other end is hingedly connected to the first driving rod 43. The end of the first driving rod 43 away from the first connecting diagonal rod 44 is sleeved in the first guiding cylinder 42 and is slidably connected to the first guiding cylinder 42. The first guiding cylinder 42 is fixedly connected to the bed frame 1. One end of the first crank 41 is rotatably connected to the bed frame 1, and the other end extends into the first guiding cylinder 42 and is threadedly connected to the first driving rod 43. Rotating the first crank 41 can drive the first driving rod 43 to move along the first guiding cylinder 42, and further enable the first connecting diagonal rod 44 to drive the first flipping bedplate 3 to flip. The first driving mechanism 4 realizes the flipping action of the first flipping bedplate 3 through a simple mechanical transmission method. The first crank 41 is convenient for the operator to manually control. The first guiding cylinder 42 provides a stable track for the movement of the first driving rod 43, ensuring the linearity and stability of the transmission. The threaded connection between the first driving rod 43 and the first crank 41 and the hinge connection with the first connecting diagonal rod 44 enable the first flipping bedplate 3 to be accurately and smoothly flipped to the specified position and reliably positioned when the first crank 41 is rotated, facilitating the flexible adjustment of the bedplate angle according to the patient's needs.

[0035] In a preferred embodiment, the second driving mechanism 6 includes a second crank 61, a second guiding cylinder 62, a second driving rod 63 and a second connecting diagonal rod 64. One end of the second connecting diagonal rod 64 is fixedly connected to the second flipping bedplate 5, and the other end is hingedly connected to the second driving rod 63. The end of the second driving rod 63 away from the second connecting diagonal rod 64 is sleeved in the second guiding cylinder 62 and is slidably connected to the second guiding cylinder 62. The second guiding cylinder 62 is fixedly connected to the bed frame 1. One end of the second crank 61 is rotatably connected to the bed frame 1, and the other end extends into the second guiding cylinder 62 and is threadedly connected to the second driving rod 63. Rotating the second crank 61 can drive the second driving rod 63 to move along the second guiding cylinder 62, and further enable the second connecting diagonal rod 64 to drive the second flipping bedplate 5 to flip. Similar to the first driving mechanism 4, the second driving mechanism 6 realizes the precise control of the flipping action of the second flipping bedplate 5 through this mechanical structure design. By rotating the second crank 61, the operator can smoothly and reliably drive the second flipping bedplate 5 to flip to a suitable position, providing accurate support and limitation for the ischial tuberosity of the inclined patient, meeting the patient's support needs and improving comfort. At the same time, this simple manual driving method is also convenient for medical staff and family members to operate.

[0036] In a preferred embodiment, the first crank 41 includes a first rocker 411, a first coupling 412, and a first threaded rod 413. The first rocker 411 is rotatably connected to the bed frame 1. One end of the first rocker 411 is drivingly connected to the first threaded rod 413 through the first coupling 412. The end of the first threaded rod 413 away from the first coupling 412 extends into the first guide cylinder 42 and is threadedly connected to the first driving rod 43. The second crank 61 includes a second rocker 611, a second coupling 612, and a second threaded rod 613. The second rocker 611 is rotatably connected to the bed frame 1. One end of the second rocker 611 is drivingly connected to the second threaded rod 613 through the second coupling 612. The end of the second threaded rod 613 away from the second coupling 612 extends into the second guide cylinder 62 and is threadedly connected to the second driving rod 63. The refined structural design of the crank makes the power transmission more stable and reliable. The settings of the first coupling 412 and the second coupling 612 can effectively connect different components, transmit torque, and compensate for the installation errors and relative movements between components; the threaded connections of the first threaded rod 413 and the second threaded rod 613 with the driving rod can accurately control the moving distance of the driving rod, and further more precisely control the flipping angles of the first flipping bed board 3 and the second flipping bed board 5, improving the accuracy of bed body adjustment and better adapting to the individual differences and diverse needs of patients.

[0037] In a preferred embodiment, the top end of the first connecting diagonal rod 44 inclines towards the headboard 11, and the top end of the second connecting diagonal rod 64 inclines towards the footboard 12. The inclined setting of the first connecting diagonal rod 44 enables better utilization of the lever principle to generate appropriate torque and force when driving the first flipping bed board 3 to flip, so that the first flipping bed board 3 can smoothly and smoothly achieve the flipping action; similarly, the second connecting diagonal rod 64 inclines towards the footboard 12, which can more effectively drive and control the second flipping bed board 5, improving the stability and efficiency of flipping and better adjusting the bed position structure for patients. In addition, when operating the first driving mechanism 4 and the second driving mechanism 6 with both hands respectively, clockwise operation with the right hand and counterclockwise operation with the left hand can achieve the simultaneous rising of the first flipping bed board 3 and the second flipping bed board 5, and counterclockwise operation with the right hand and clockwise operation with the left hand can achieve the simultaneous descending of the first flipping bed board 3 and the second flipping bed board 5, which is convenient for medical staff to use.

[0038] In a preferred embodiment, both the first rocker 411 and the second rocker 611 are provided with markings to distinguish that the first rocker 411 controls the first flipping bed board 3 and the second rocker 611 controls the second flipping bed board 5.

[0039] In a preferred embodiment, the first driving mechanism and the second driving mechanism can also be electric telescopic rods, pneumatic telescopic rods, hydraulic telescopic rods, etc. Using electric telescopic rods, pneumatic telescopic rods, and hydraulic telescopic rods as the first driving mechanism and the second driving mechanism can bring many positive technical effects. The electric telescopic rod can achieve remote control or automated operation using an intelligent control system. Medical staff can conveniently adjust the angles of the first flipping bed board and the second flipping bed board with an electronic device, greatly improving the adjustment efficiency, especially suitable for emergency medical scenarios or patients who need frequent position adjustment; the motor driving accuracy of the electric telescopic rod is high, enabling the flipping bed board to accurately and stably reach the set position to meet the precise position requirements of different patients. The pneumatic telescopic rod uses compressed air as the power source and has the characteristics of rapid response, capable of achieving rapid flipping of the bed board within a short time; in addition, the pneumatic system structure is relatively simple, and the maintenance cost is low. Long-term use can help hospitals reduce equipment operation and maintenance expenses. The hydraulic telescopic rod has a powerful driving force and can easily handle the flipping action of the relatively heavy flipping bed board, ensuring the load-bearing capacity of the system; the smoothness of hydraulic transmission is excellent, which can ensure that the first flipping bed board and the second flipping bed board have a smooth transition during the flipping process, reducing the discomfort of patients caused by the shaking of the bed board and providing a more comfortable and safe support experience for patients. These diverse driving mechanism options greatly enrich the driving methods of the medical bed, enabling the medical bed to better adapt to different medical scenarios and patient needs.

[0040] In a preferred embodiment, it further includes a support slide rail. The support slide rail is installed on the bed frame 1 and is located between the fixed bed board 2 and the bed tail baffle 12. One end of the third flipping bed board 7 away from the second flipping bed board 5 is slidably connected to the support slide rail. The support slide rail can provide stable support for the second flipping bed board 5 after it is reset. The support slide rail provides stable support and a sliding track for the third flipping bed board 7, ensuring the smoothness and reliability of the third flipping bed board 7 during the sliding process. Acting in coordination with other connection structures of the third flipping bed board 7, it enables the bed body to maintain the stability of the overall structure during the deformation process, meeting the requirements of the patient for the firmness and reliability of the bed body when adjusting to different postures.

[0041] In a preferred embodiment, it further includes a plurality of support rods. The support rods are installed on one side of the bed frame 1 near the head board 11 to support the reset first flipping bed board 3. When the first flipping bed board 3 is reset, the support rods can provide additional support force for it, sharing the pressure of the patient's weight on the bed board, enhancing the load-bearing capacity of the bed board, improving the stability of the first flipping bed board 3 after reset, extending the service life of the bed board, and at the same time reducing the risk of deformation that may occur due to long-term pressure on the bed board, ensuring the safety and comfort of patients during use.

[0042] In a preferred embodiment, it further includes four medical universal silent rollers 8. The four medical universal silent rollers 8 are installed at the four corners of the bottom of the bed frame 1. The design of the medical universal silent rollers 8 enables the medical bed to turn flexibly during movement, and can be easily carried and moved in different areas such as wards and corridors, facilitating operations such as patient transfer and equipment position adjustment; the characteristics of the silent rollers effectively reduce the noise generated during the movement of the bed body, providing a quiet medical environment for patients and reducing interference with patients' rest.

[0043] In a preferred embodiment, in the length direction of the bed board, the size of the first flip bed board is 80 cm, the size of the fixed bed board is 7 cm, the size of the second flip bed board is 20 cm, and the size of the third flip bed board is 90 cm.

[0044] The present invention also provides a method for using a medical bed as described in any one of the above, including the following steps:

[0045] Lying and basic adjustment

[0046] Supine position: The patient lies directly on the fixed bed board 2, and the side guardrails 13 erected on both sides can ensure the safety of the patient and prevent the patient from rolling off during sleep. If the side guardrails 13 are not needed, they can be stored in a suitable state through the guardrail flip buckle, facilitating the patient to get on and off the bed by himself.

[0047] Oblique position: The operator rotates the first crank 41, and the first crank 41 drives the first threaded rod 413 to rotate. Since the first threaded rod 413 is threadedly connected to the first drive rod 43, and the first drive rod 43 slides in the first guide cylinder 42, the first drive rod 43 moves along the first guide cylinder 42. Through the first connecting diagonal rod 44, the first flip bed board 3 is turned upward around the rotation connection with the fixed bed board 2 to the angle required by the patient, and the patient is adjusted to the oblique position accordingly, facilitating the patient to eat, watch TV or receive treatment, etc.

[0048] Precise support adjustment

[0049] According to the mechanics of human sitting postures, the main bony structures that bear the force when the buttocks touch the chair during sitting are the "left and right ischial tuberosities". When lying obliquely, the gravity falls on the second flipping bed board from the ischial tuberosities and the human body will not slide down. Therefore, this medical bed is designed with the "ischial tuberosity" as the "fundamental force-bearing point for lying obliquely". When the patient is in the oblique lying state, in order to prevent the patient from sliding down and to provide better support and limitation for the patient's ischial tuberosity area, the operator can rotate the second crank 61. The second crank 61 drives the second threaded rod 613 to rotate, and the second threaded rod 613 drives the second driving rod 63 to slide within the second guiding cylinder 62. Through the second connecting diagonal rod 64, it drives the second flipping bed board 5 to rotate upwards around the rotational connection with the fixed bed board 2 to an appropriate position, providing reliable support for the patient's ischial tuberosity area to prevent the occurrence of sliding, reducing the pressure on this area, and preventing problems such as bedsores.

[0050] Since one end of the third flipping bed board 7 is rotationally connected to the end of the second flipping bed board 5 that is away from the fixed bed board 2, and the other end is slidably connected to the support slide rail, when adjusting the positions of the first flipping bed board 3 and the second flipping bed board 5, the third flipping bed board 7 will, under the action of the sliding and rotational connections, automatically adjust to an appropriate position in coordination with the change in the overall bed shape, providing more comprehensive and body-conforming support for the patient. For example, when the patient needs support for the calves and body curve support, the coordinated movement of the third flipping bed board 7 can meet these personalized needs.

[0051] Bed stability guarantee (support rods and rollers)

[0052] In daily use, the reset first flipping bed board 3 will be more stable due to being supported by multiple support rods, and can bear a greater weight without being easily deformed. The patient does not need to perform special operations on these support rods during use.

[0053] When it is necessary to move the medical bed, medical staff or workers push the bed body, and the medical universal silent rollers 8 installed at the four corners of the bottom enable the bed body to turn left and right and translate flexibly. Due to the silent characteristics of the rollers, no large noise will be generated during the movement process, and it will not interfere with the patient's rest and the medical environment.

[0054] Medical staff and maintenance and usage methods

[0055] Daily inspection and maintenance

[0056] Regularly check the connection conditions of each component, such as whether the connection between the side guardrail 13 and the bed frame 1, and the connection between the flipping bed board and the fixed bed board 2 and the drive mechanism are firm; check whether the guardrail flipping buckle, crank, etc. can operate normally and whether there is looseness.

[0057] Check the rotational flexibility of the medical universal silent rollers 8 to ensure that there is no jamming or wear. When necessary, perform cleaning, lubrication, or replacement.

[0058] Troubleshooting and Maintenance

[0059] If it is found that the first flipping bed board 3 or the second flipping bed board 5 cannot flip normally during use, first check whether components such as the crank, drive rod, and connecting diagonal rod are damaged or disengaged; check whether the sliding fit between the drive rod and the guide cylinder is smooth and whether the threaded connection is worn. If components need to be repaired or replaced, disassemble and install them according to the design structure.

[0060] If the third flipping bed board 7 has problems such as unsmooth sliding or stuck rotation, check whether there is foreign matter blocking the support slide rail, whether there is deformation or damage at the sliding connection; whether the components at the rotating connection are normal, and clean or repair the relevant components in time to ensure the normal use of each function of the bed body.

[0061] In the present invention, specific examples are used to illustrate the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present invention.
