[0002] With the increasing aging of the population, the demand for medical beds in hospitals or at home is growing among the elderly. Traditional medical beds typically only have a head and backrest lift function, and when a patient rolls from a supine position to a reclining position, the bed tends to slip. This not only causes discomfort for the patient, who then has to grit their teeth and crawl back to their seat or rely on family members or caregivers to lift them, increasing the burden on both the patient and caregivers, but also, due to repeated friction and pressure on the patient's body, pressure sores are easily formed on the sacrum and coccyx, affecting the patient's health and recovery process.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] The purpose of this invention is to provide a medical bed that solves the problems existing in the prior art. It has a simple structure, is easy to use, effectively solves the problem of patients sliding down when lying on their side, and reduces the occurrence of pressure sores caused by friction and pressure, thus effectively improving the comfort of patients in the lying position.
[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0027] Example 1
[0028] This utility model provides a medical bed, including: a bed frame 1, two side rails 13, two rail flip-up buckles, a fixed bed board 2, a first flip-up bed board 3, a first drive mechanism 4, a second flip-up bed board 5, and a second drive mechanism 6. The top of the bed frame 1 is provided with a headboard 11 and a footboard 12 at both ends, which provide boundary protection for the patient and prevent the patient from falling during sleep. The two side rails 13 are respectively installed on both sides of the top of the bed frame 1. The rail flip-up buckles are used to confine the side rails 13 to an upright or retracted state. When the side rails 13 are upright, they can protect the patient's safety and prevent them from rolling off. When the side rails 13 are retracted by the rail flip-up buckles, it is convenient for the patient to get in and out of bed.
[0029] The fixed bed board 2 is fixedly connected to the middle of the top of the bed frame 1, providing a stable support base for the patient; one end of the first flip bed board 3 is rotatably connected to the side of the fixed bed board 2 near the headboard 11 and can be limited to the designed position, allowing the patient to adjust to a suitable reclining angle, which helps to improve the patient's comfort, such as facilitating the patient to eat or watch; the fixed end of the first drive mechanism 4 is used to be fixedly connected to the bed frame 1, and the drive end of the first drive mechanism 4 is used to drive the end of the first flip bed board 3 away from the fixed bed board 2 to flip upward or reset and maintain the flipped position.
[0030] One end of the second tilting bed board 5 is rotatably connected to the side of the fixed bed board 2 near the footboard 12 and can be limited to the designed position. It supports and limits the ischial tuberosity of the obliquely reclining patient, which can effectively reduce the pressure on the patient in this area, prevent the obliquely reclining patient from sliding down, effectively avoid repeated friction on the patient's body when sliding down, avoid pressure sores on the sacrum and coccyx, and effectively ensure the patient's health and rehabilitation process. The fixed end of the second drive mechanism 6 is used to be fixedly connected to the bed frame 1, and the drive end of the second drive mechanism 6 is used to drive the end of the second tilting bed board 5 away from the fixed bed board 2 to tilt upward or reset and maintain the tilted position.
[0031] In a preferred embodiment, the medical bed further includes a third tilting bed board 7. One end of the third tilting bed board 7 is rotatably connected to the end of the second tilting 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 tilting bed board 7 further enriches the adjustment function of the medical bed and can adapt to the bending of the lower legs. Its rotatable connection with the second tilting bed board 5 and its slidable connection with the bed frame 1 can flexibly adjust the bed position according to the different posture needs and physical conditions of the patient, so that the patient can obtain a more suitable support and lying experience.
[0032] In a preferred embodiment, the first drive mechanism 4 includes a first crank 41, a first guide cylinder 42, a first drive rod 43, and a first connecting inclined rod 44. One end of the first connecting inclined rod 44 is fixedly connected to the first tilting bed board 3, and the other end is hingedly connected to the first drive rod 43. The end of the first drive rod 43 away from the first connecting inclined rod 44 is sleeved in the first guide cylinder 42 and slidably connected to the first guide cylinder 42. The first guide 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 guide cylinder 42 and is threadedly connected to the first drive rod 43. Rotating the first crank 41 can drive the first drive rod 43 to move along the first guide cylinder 42, thereby causing the first connecting inclined rod 44 to drive the first tilting bed board 3 to tilt. The first drive mechanism 4 realizes the tilting action of the first tilting bed board 3 through a simple mechanical transmission method. The first crank handle 41 facilitates manual control by the operator, and the first guide cylinder 42 provides a stable track for the movement of the first drive rod 43, ensuring the linearity and stability of the transmission. The threaded connection between the first drive rod 43 and the first crank handle 41, as well as the hinge connection with the first connecting diagonal rod 44, enable the first tilting bed board 3 to be accurately and smoothly tilted to the designated position and reliably positioned when the first crank handle 41 is rotated, facilitating flexible adjustment of the bed board angle according to the patient's needs.
[0033] In a preferred embodiment, the second drive mechanism 6 includes a second crank 61, a second guide cylinder 62, a second drive rod 63, and a second connecting inclined rod 64. One end of the second connecting inclined rod 64 is fixedly connected to the second tilting bed board 5, and the other end is hinged to the second drive rod 63. The end of the second drive rod 63 away from the second connecting inclined rod 64 is sleeved in the second guide cylinder 62 and slidably connected to the second guide cylinder 62. The second guide 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 guide cylinder 62 and is threadedly connected to the second drive rod 63. Rotating the second crank 61 can drive the second drive rod 63 to move along the second guide cylinder 62, thereby causing the second connecting inclined rod 64 to drive the second tilting bed board 5 to tilt. Similar to the first drive mechanism 4, the second drive mechanism 6 achieves precise control of the tilting action of the second tilting bed board 5 through this mechanical structure design. By turning the second crank 61, the operator can smoothly and reliably rotate the second tilting bed board 5 to the appropriate position, providing accurate support and restraint for the ischial tuberosity of the patient in a reclining position, meeting the patient's support needs and improving comfort. At the same time, this simple manual drive method is also convenient for medical staff and family members to operate.
[0034] In a preferred embodiment, the first crank handle 41 includes a first rocker arm 411, a first coupling 412, and a first threaded rod 413. The first rocker arm 411 is rotatably connected to the bed frame 1. One end of the first rocker arm 411 is drivenly 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 drive rod 43. The second crank handle 61 includes a second rocker arm 611, a second coupling 612, and a second threaded rod 613. The second rocker arm 611 is rotatably connected to the bed frame 1. One end of the second rocker arm 611 is drivenly 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 drive rod 63. The refined structural design of the crank handle makes the power transmission more stable and reliable. The first coupling 412 and the second coupling 612 can effectively connect different components, transmit torque, and compensate for installation errors and relative movements between components; the threaded connection between the first threaded rod 413 and the second threaded rod 613 and the drive rod can precisely control the movement distance of the drive rod, thereby more accurately controlling the flipping angle of the first flipping bed board 3 and the second flipping bed board 5, improving the accuracy of bed adjustment, and better adapting to individual differences and diverse needs of patients.
[0035] In a preferred embodiment, the top of the first connecting rod 44 is inclined towards the headboard 11, and the top of the second connecting rod 64 is inclined towards the footboard 12. This inclined arrangement of the first connecting rod 44 allows for better utilization of the lever principle to generate appropriate torque and force when the first tilting bed board 3 is tilted, thus enabling the first tilting bed board 3 to tilt smoothly and steadily. Similarly, the inclination of the second connecting rod 64 towards the footboard 12 allows for more effective driving and control of the second tilting bed board 5, improving the stability and efficiency of the tilting and better adjusting the bed position for the patient. Furthermore, when operating the first drive mechanism 4 and the second drive mechanism 6 with both hands, clockwise operation with the right hand and counterclockwise operation with the left hand allows the first tilting bed board 3 and the second tilting bed board 5 to rise simultaneously, while counterclockwise operation with the right hand and clockwise operation with the left hand allows the first tilting bed board 3 and the second tilting bed board 5 to fall simultaneously, facilitating use by medical staff.
[0036] In a preferred embodiment, both the first rocker arm 411 and the second rocker arm 611 are marked to distinguish whether the first rocker arm 411 controls the first tilting bed board 3 or the second rocker arm 611 controls the second tilting bed board 5.
[0037] In a preferred embodiment, the first and second drive mechanisms can also be electric telescopic rods, pneumatic telescopic rods, and hydraulic telescopic rods, etc. Using electric, pneumatic, or hydraulic telescopic rods as the first and second drive mechanisms can bring many positive technical benefits. Electric telescopic rods can be remotely controlled or automated using an intelligent control system. Medical staff can conveniently adjust the angles of the first and second tilting bed boards using electronic devices, significantly improving adjustment efficiency, especially suitable for emergency medical scenarios or patients requiring frequent repositioning. The high precision of the electric telescopic rod's motor drive ensures the tilting bed board accurately and stably reaches the set position, meeting the precise positioning needs of different patients. Pneumatic telescopic rods use compressed air as a power source, featuring rapid response and enabling quick tilting of the bed board. Furthermore, the pneumatic system has a relatively simple structure and low maintenance costs, helping hospitals reduce equipment operation and maintenance expenses in the long term. The hydraulic telescopic rod possesses powerful driving force, easily handling the tilting motion of heavy bed boards and ensuring the system's load-bearing capacity. The excellent smoothness of the hydraulic transmission ensures a gentle transition between the first and second tilting bed boards during tilting, reducing patient discomfort caused by bed board swaying and providing a more comfortable and safer support experience. These diverse drive mechanism options greatly enrich the driving methods of medical beds, allowing them to better adapt to different medical scenarios and patient needs.
[0038] In a preferred embodiment, a support slide rail is also included. The support slide rail is installed on the bed frame 1 and located between the fixed bed board 2 and the footboard 12. The end of the third tilting bed board 7 away from the second tilting bed board 5 is slidably connected to the support slide rail. The support slide rail can provide stable support for the second tilting bed board 5 after it is reset. The support slide rail provides stable support and a sliding track for the third tilting bed board 7, ensuring the stability and reliability of the third tilting bed board 7 during the sliding process. It works in conjunction with other connecting structures of the third tilting bed board 7 to enable the bed to maintain the stability of the overall structure during deformation, meeting the patient's requirements for the sturdiness and reliability of the bed when adjusting different postures.
[0039] In a preferred embodiment, the system further includes multiple support rods installed on the side of the bed frame 1 near the headboard 11 to support the repositioned first tilting bed board 3. When the first tilting bed board 3 is repositioned, the support rods can provide additional support force to share the pressure of the patient's weight on the bed board, enhance the load-bearing capacity of the bed board, improve the stability of the first tilting bed board 3 after repositioning, extend the service life of the bed board, and reduce the risk of deformation that may occur due to long-term pressure on the bed board, thus ensuring the safety and comfort of the patient.
[0040] In a preferred embodiment, the bed also includes four medical universal silent casters 8, which are installed at the four bottom corners of the bed frame 1. The design of the medical universal silent casters 8 allows the medical bed to turn flexibly during movement, making it easy to move and transport in different areas such as wards and corridors, facilitating patient transfers, equipment adjustments, and other operations. The silent casters effectively reduce the noise generated during bed movement, providing a quiet medical environment for patients and reducing interference with their rest.
[0041] In a preferred embodiment, along the length of the bed board, the first flip-up bed board has a dimension of 80cm, the fixed bed board has a dimension of 7cm, the second flip-up bed board has a dimension of 20cm, and the third flip-up bed board has a dimension of 90cm.
[0042] This utility model also provides a method of using the medical bed as described in any of the above claims, comprising the following steps:
[0043] Lying down and basic adjustment
[0044] Supine position: The patient lies directly on the fixed bed board 2. The vertical side rails 13 on both sides ensure the patient's safety and prevent them from rolling off during sleep. If the side rails 13 are not needed, they can be folded into a suitable position using the rail flip-up buckles, making it convenient for the patient to get in and out of bed on their own.
[0045] Reclining position: The operator turns the first crank 41, which 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 inclined rod 44, the first tilting bed board 3 is tilted upward around the rotational connection with the fixed bed board 2 to the angle required by the patient. The patient is then adjusted to a reclining position, which is convenient for the patient to eat, watch TV or receive treatment.
[0046] Precise support and adjustment
[0047] Based on the mechanics of human sitting posture, the main bony structures bearing the force of the buttocks when sitting are the left and right ischial tuberosities. When lying obliquely, the weight is distributed from the ischial tuberosities onto the second tilting bed board, preventing the body from sliding down. Therefore, this medical bed was designed with the ischial tuberosities as the "fundamental force-bearing point" for oblique lying. When the patient is in an oblique lying position, to prevent the patient from sliding down and to provide better support and restraint for the ischial tuberosities, 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 drive rod 63 to slide within the second guide cylinder 62. Through the second connecting diagonal rod 64, the second tilting bed board 5 is tilted upwards around the rotating connection point with the fixed bed board 2 to a suitable position, providing reliable support for the patient's ischial tuberosities to prevent sliding down, reducing pressure on this area, and preventing problems such as bedsores.
[0048] Because one end of the third tilting bed board 7 is rotatably connected to the end of the second tilting bed board 5 away from the fixed bed board 2, and the other end is slidably connected to the support rail, when the positions of the first tilting bed board 3 and the second tilting bed board 5 are adjusted, the third tilting bed board 7 will automatically adjust to a suitable position under the action of sliding and rotating connections, in accordance with the changes in the overall bed shape, providing the patient with more comprehensive and body-fitting support. For example, when the patient needs support for their lower legs or body curves, the coordinated movement of the third tilting bed board 7 can meet these personalized needs.
[0049] Bed stability assurance (support rods and casters)
[0050] In daily use, the first tilting bed board 3, after being reset, is more stable due to the support of multiple support rods, and can withstand greater weight without easily deforming. Patients do not need to perform any special operations on these support rods during use.
[0051] When the medical bed needs to be moved, medical staff or workers push the bed, and the medical universal silent casters installed at the four corners of the bottom allow the bed to flexibly turn left and right and move horizontally. Due to the silent nature of the casters, no significant noise is generated during the movement, and it will not disturb the patient's rest or the medical environment.
[0052] Medical staff and maintenance and usage methods
[0053] Routine inspection and maintenance
[0054] Regularly check the connections of each component, such as whether the connection between the side guardrail 13 and the bed frame 1, the connection between the flip bed board and the fixed bed board 2 and the drive mechanism are secure; check whether the guardrail flip buckle, crank, etc. can operate normally and whether they are loose.
[0055] Check the rotational flexibility of the medical universal silent roller 8 to ensure there is no jamming or wear, and clean, lubricate or replace it if necessary.
[0056] Troubleshooting and Repair
[0057] If the first tilting bed board 3 or the second tilting bed board 5 fails to tilt properly during use, first check whether the crank, drive rod, and connecting diagonal rod are damaged or detached; check whether the sliding fit between the drive rod and the guide cylinder is smooth and whether the threaded connection is worn. If repair or replacement of parts is required, disassembly and installation should be carried out according to the design structure.
[0058] If the third tilting bed board 7 experiences difficulty in sliding or jamming during rotation, check if there are any foreign objects blocking the support slide rails, or if there is any deformation or damage at the sliding connection points; check if the components at the rotating connection points are normal, and clean or repair the relevant components in a timely manner to ensure the normal use of all functions of the bed.
[0059] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
