Description

Technical Field

[0001] The invention belongs to the field of medical care equipment, and in particular relates to a care bed for intelligent treatment of defecation and urination. Background Art

[0002] With the aging of the population and the increase in the number of patients with chronic diseases, the nursing needs of long-term bedridden patients are becoming increasingly prominent. Traditional nursing beds rely on manual assistance or simple bedpans to solve the problem of patients' urination and defecation. They are inconvenient to operate, have poor sanitary conditions, and are prone to skin infections. This not only increases the workload of nursing staff, but also affects the quality of life and rehabilitation process of patients.

[0003] Although some smart nursing beds are equipped with automatic defecation devices in an attempt to improve this situation, there are still many shortcomings. First, the partition structure of the bed body usually adopts a rigid fixed design and cannot be dynamically adjusted according to the changes in the patient's body position. This leads to side leakage or contamination of the mattress during excretion, which not only increases the cleaning workload, but also may cause the risk of cross infection. Secondly, the closure of the toilet trough cleaning system is often not ideal, resulting in prominent odor diffusion problems, affecting the sanitation of the ward environment and the comfort of patients.

[0004] In addition, the existing intelligent nursing beds often have a relatively simple body adjustment mechanism, lacking coordinated support for the patient's back, buttocks and limbs. This makes it easy for patients to feel uncomfortable when sitting on the toilet, and even risk slipping, increasing the possibility of secondary injury. At the same time, the overall functional integration of the nursing bed is low, and auxiliary functions such as lifting and rotating lack effective linkage with the defecation module, which invisibly increases the complexity of nursing staff's operations and reduces nursing efficiency.

[0005] More importantly, existing smart nursing beds do not take into account the protection of patient privacy. During the excretion process, patients are often exposed and lack the necessary shielding measures, which may cause psychological pressure on patients and is not conducive to their physical and mental health.

[0010] Furthermore, the present application also proposes that the toilet seat protection drive unit includes a second drive cylinder hinged to the bed frame, and the telescopic end of the second drive cylinder is hinged with a second crankshaft connecting rod assembly for driving the third partition plates on both sides to rotate.

[0011] Furthermore, the present application also proposes that the back-lifting driving part is hingedly connected to the first driving cylinder of the bed frame, and the output end of the first driving cylinder is hingedly connected to a first crankshaft connecting rod assembly for driving the second partition plate in the middle position to rotate.

[0012] Furthermore, the present application also proposes that the leg support driving part includes a third driving cylinder hinged to the bed frame, the telescopic end of the third driving cylinder is hinged with a third crankshaft connecting rod assembly, and the end of the third crankshaft connecting rod assembly away from the third driving cylinder has a supporting frame for simultaneously supporting three fourth partition boards.

[0013] Furthermore, the present application also proposes that it also includes a defecation control switch and a controller, and the defecation control switch is electrically connected to the controller to control the back-lifting drive unit, the toilet protection drive unit, and the leg support drive unit through the controller to start driving the first partition plate, the second partition plate, the third partition plate, and the fourth partition plate to the specified position.

[0017] Due to the adoption of the above technical solution, the beneficial effects achieved by the present invention are as follows:

[0018] 1. By dividing the bed frame into multiple hinged partitions, the nursing bed can be dynamically adjusted according to the patient's body position changes to avoid side leakage or contamination of the mattress during excretion. Secondly, the design of the back-lifting drive unit and the toilet protection drive unit provides coordinated support for the patient's back, buttocks and limbs, reducing the patient's discomfort or risk of slipping in the toilet position. In addition, the overall functional integration of the nursing bed is high, and auxiliary functions such as lifting and rotating are closely linked with the defecation module, simplifying the operation of nursing staff.

[0019] The back-lifting drive unit is started to rotate the second partition plate in the middle upwards, and the patient's back is supported to an angle of 45-75° with the horizontal plane. At the same time, the toilet protection drive unit is started to rotate the third partition plates on both sides upwards to an angle of 45-75° with the horizontal plane and cooperate with the third partition plate in the middle to form a C-shaped protection structure, which semi-encloses the patient's buttocks. The third partition plates on both sides simultaneously drive the second partition plates on both sides through the hinge points to rotate upwards and cooperate with the second partition plate in the middle to form a C-shaped protection structure, which semi-encloses the patient's back. On the one hand, it can limit the patient's position, correct the posture of unconscious patients, and thirdly, it can prevent the patient from slipping off the bed.

[0020] From the above, it can be seen that the present application can realize dynamic adjustment of the bed partitions to form a C-shaped protective structure, which effectively solves the side leakage, pollution and privacy protection problems of traditional nursing beds during the excretion process, and has the advantages of improving the patient's excretion experience, improving nursing efficiency and protecting patient privacy.

[0021] 2. The nursing bed can dynamically adjust the leg support area to ensure the comfort and stability of the patient's legs during use. The leg support drive unit can synchronously drive the three fourth partition plates to rotate downward around the hinge point through the drive cylinder and crankshaft connecting rod assembly hinged to the bed frame, forming support and protection for the patient's legs. Furthermore, the third partition plates on both sides drive the fourth partition plates to rotate upward, so that the fourth partition plates can form a C-shaped protective structure to provide better support effect.

[0022] Compared with traditional nursing beds, this application can adjust the leg support area according to the patient's posture changes, provide better comfort and stability, and reduce the patient's discomfort and slip risk during use. At the same time, the design of the C-shaped protection structure further improves the protection effect on the patient's legs, reduces the complexity of nursing staff's operations, and improves nursing efficiency.

[0023] 3. By setting up three first partition panels in the head support area, they can work together with the second partition panels to form a C-shaped protection structure, thereby providing additional support and protection when the patient is using it, avoiding accidents caused by movement or posture adjustment.

[0024] The three first partition plates of the head support area are connected to the second partition plates by hinges. When the second partition plates rotate along the hinge points, the first partition plates can be driven to rotate upward synchronously. Thus, the three first partition plates 0 can form a C-shaped protective structure to effectively support and protect the patient's head and neck area.

[0025] 4. By setting up a defecation control switch and a controller, unified control of the back-raising drive unit, the toilet protection drive unit, and the leg support drive unit can be achieved, so that each partition plate can be driven to a specified position. Specifically, the defecation control switch can start each drive unit through an electrically connected controller, so that different partition plates of the nursing bed can be adjusted and moved as needed. This design not only improves the automation level of the nursing bed, but also effectively solves many problems of traditional nursing beds in handling defecation and urination.

[0026] The setting of the defecation control switch and the controller allows the nursing staff to control the movement and adjustment of each partition plate of the nursing bed through simple operations. For example, the back-lifting drive unit can make the partition plate of the back support area rise or fall, the toilet protection drive unit can rotate the partition plate of the hip support area upward to form a protective structure, and the leg support drive unit can adjust the position of the partition plate of the leg support area. These operations can be achieved through the defecation control switch, which greatly facilitates the operation of the nursing staff.

[0027] By setting a defecation control switch and a controller, the present application can realize automatic control of different partition boards of the nursing bed. Compared with the prior art, it significantly improves the convenience of use and functional integration of the nursing bed, and solves the problems of inconvenient operation and poor sanitary conditions in handling defecation and urination of traditional nursing beds. Therefore, the present application not only improves the comfort and safety of patients, but also reduces the workload of nursing staff. BRIEF DESCRIPTION OF THE DRAWINGS

Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0041] Reference Figures 1 to 5 The present application proposes a nursing bed with intelligent defecation and urination treatment, which includes a bed frame 10, the width direction of the bed frame 10 is X, the length direction is Y, and the bed frame 10 is provided with a head support area, a back support area, a buttocks support area and a leg support area that are hinged to each other in sequence along the Y direction. The back support area is composed of three second partition plates 30 arranged in sequence along the X direction and hinged to each other, and the buttocks support area is composed of three third partition plates 40 arranged in sequence along the X direction and intersecting with each other, and the three second partition plates 30 are hinged to the three third partition plates 40 respectively. The toilet trough 401 is arranged on the third partition plate 40 in the middle position, and a feces cleaning device for cleaning the toilet trough 401 is provided below the bed frame 10. The back-lifting drive unit is arranged below the bed frame 10 and is connected to the second partition plate 30 located in the middle to drive the second partition plate 30 to rotate along the hinge point. The toilet protection drive unit is located below the bed frame 10 and is symmetrically provided with two groups. The two groups of toilet protection drive units are respectively connected to the third partition plates 40 on both sides. When the user is convenient, the third partition plates 40 on both sides are driven to rotate upward along the hinge points to cooperate with the third partition plate 40 in the middle to form a C-shaped protection structure. At the same time, the third partition plates 40 on both sides drive the adjacent second partition plates 30 to rotate synchronously, so that the second partition plates 30 on both sides cooperate with the second partition plates 30 in the middle to form a C-shaped protection structure.

[0042] The design of the nursing bed aims to solve the technical problems existing in traditional nursing beds. First, by dividing the bed frame 10 into a plurality of hinged partition panels, the nursing bed can be dynamically adjusted according to the changes in the patient's body position to avoid side leakage or contamination of the mattress during excretion. Secondly, the toilet trough 401 is arranged on the third partition panel 40 in the middle position and is equipped with a fecal cleaning device to ensure the closedness of the toilet trough 401 cleaning system and effectively solve the problem of odor diffusion. Thirdly, the design of the back-lifting drive unit and the toilet protection drive unit provides coordinated support for the patient's back, buttocks and limbs, reducing the patient's discomfort or risk of slipping in the toilet posture. In addition, the overall functional integration of the nursing bed is high, and auxiliary functions such as lifting and rotating are closely linked with the defecation module, which simplifies the operation of nursing staff.

[0043] Through the above technical solutions, the nursing bed of the present application provides a variety of possible implementation methods for solving the problem of urination and defecation of patients, and realizes all-round support and protection for patients through the association and interaction between various components. For example, the back-lifting drive unit realizes dynamic adjustment of the back support area through the cooperation of the first drive cylinder 32 and the first crankshaft connecting rod assembly 33, thereby ensuring the comfort of the patient. The toilet protection drive unit realizes dynamic adjustment of the buttocks support area through the cooperation of the second drive cylinder 42 and the second crankshaft connecting rod assembly 43, forming a C-shaped protective structure to ensure safety and hygiene during excretion. The leg support drive unit realizes dynamic adjustment of the leg support area through the cooperation of the third drive cylinder 52 and the third crankshaft connecting rod assembly 53, providing support and protection for the patient's legs.

[0044] It is worth mentioning that when defecation is needed, the back-lifting drive unit starts to rotate the second partition plate 30 in the middle upwards, supporting the patient's back to an angle of 45-75° with the horizontal plane. At the same time, the toilet protection drive unit starts to rotate the third partition plates 40 on both sides upwards to an angle of 45-75° with the horizontal plane and cooperate with the third partition plate 40 in the middle to form a C-shaped protection structure, which semi-encloses the patient's buttocks. The third partition plates 40 on both sides simultaneously drive the second partition plates 30 on both sides to rotate upwards through the hinge point to cooperate with the second partition plate 30 in the middle to form a C-shaped protection structure, which semi-encloses the patient's back. On the one hand, it can limit the patient's position, on the other hand, it can correct the posture of unconscious patients, and on the third hand, it can prevent the patient from slipping off the bed.

[0045] In summary, the nursing bed with intelligent defecation and urination processing of the present application effectively solves many problems existing in the defecation and urination processing of traditional nursing beds through innovative design and multiple technical means, thereby improving the comfort of patients and the work efficiency of nursing staff.

[0046] As a preferred embodiment of the present application, refer to Figure 1-Figure 5The present application also proposes that the leg support area is composed of three fourth partition plates 50 which are arranged in sequence along the X direction and hinged to each other. The three third partition plates 40 are hinged to the three fourth partition plates 50 respectively. A leg support driving part is provided under the bed frame 10 for driving the three fourth partition plates 50 to rotate downward synchronously around the hinge points with the third partition plates 40. The third partition plates 40 on both sides drive the fourth partition plates 50 on both sides to rotate upward so that the three fourth partition plates 50 form a C-shaped protective structure.

[0047] Through the above technical solution, the nursing bed of the present application can realize dynamic adjustment of the leg support area to ensure the comfort and stability of the patient's legs during use. The leg support drive unit can synchronously drive the three fourth partition plates 50 to rotate downward around the hinge point through the drive cylinder and crankshaft connecting rod assembly hinged to the bed frame 10, forming support and protection for the patient's legs. Furthermore, the third partition plates 40 located on both sides drive the fourth partition plates 50 to rotate upward, so that the fourth partition plates 50 can form a C-shaped protective structure to provide better support effect.

[0048] The newly added leg support area is composed of three fourth partition plates 50, which are connected by an articulated manner and can be adjusted according to the different postures of the patient's legs. The leg support drive unit includes a driving cylinder hinged to the bed frame 10, and the telescopic end of the driving cylinder is connected to the fourth partition plate 50 through a crankshaft connecting rod assembly, thereby realizing synchronous drive. Specifically, the telescopic action of the driving cylinder can drive the crankshaft connecting rod assembly to rotate, so that the fourth partition plate 50 can be adjusted around the hinge point to achieve a supporting effect on the legs. As a preferred embodiment, the driving cylinder and the crankshaft connecting rod assembly can be driven electrically or pneumatically to achieve more precise control.

[0049] This application solves the shortcomings of existing nursing beds in terms of leg support by adding a dynamic adjustment function to the leg support area. Compared with traditional nursing beds, this application can adjust the leg support area according to the patient's posture changes, provide better comfort and stability, and reduce the patient's discomfort and risk of slipping during use. At the same time, the design of the C-type protection structure further improves the protection effect on the patient's legs, reduces the complexity of nursing staff's operations, and improves nursing efficiency.

[0050] Furthermore, the present application also proposes that the head support area is composed of three first partition panels 20 arranged in sequence along the X-direction and hinged to each other, the three first partition panels 20 are respectively hinged to the three adjacent second partition panels 30, and the second partition panels 30 located on both sides drive the first partition panels 20 located on both sides to rotate upward so that the three first partition panels 20 form a C-shaped protective structure.

[0051] The purpose of this technical solution is to set up three first partition panels 20 in the head support area so that they can work together with the second partition panels 30 to form a C-shaped protective structure, thereby providing additional support and protection when the patient uses it, thereby avoiding accidents caused by movement or posture adjustment of the patient.

[0052] Specifically, the three first partition plates 20 in the head support area are connected to the second partition plate 30 by hinges, and when the second partition plate 30 rotates along the hinge point, it can drive the first partition plate 20 to rotate upward synchronously. Thus, the three first partition plates 20 can form a C-shaped protective structure to effectively support and protect the patient's head and neck area.

[0053] As a preferred embodiment, the first partition plate 20 of the head support area can be made of high-strength and soft materials to ensure that it does not cause discomfort to the patient's head and neck while providing support. At the same time, the design of the hinge point should take into account durability and flexibility to ensure that the hinge part will not become loose or damaged during long-term use.

[0054] The head support area design of the present application can better adapt to the patient's body position changes, provide stable and comfortable support, and reduce the discomfort and risks caused by improper head and neck posture during use. In addition, by working in coordination with the second partition plate 30, the head support area can automatically form a protective structure when the patient adjusts his posture, thereby improving the intelligence level and convenience of use of the nursing bed.

[0055] As a specific implementation of the toilet seat protection drive unit, refer to Figure 5 The toilet protection driving unit includes a second driving cylinder 42 hinged to the bed frame 10, and the telescopic end of the second driving cylinder 42 is hinged with a second crankshaft connecting rod assembly 43 for driving the third partition plates 40 on both sides to rotate.

[0056] The toilet seat protection drive unit can effectively drive the third partition plates 40 on both sides to rotate through the cooperation of the second drive cylinder 42 and the second crankshaft connecting rod assembly 43, thereby forming a C-shaped protection structure. The telescopic action of the second drive cylinder 42 is transmitted to the third partition plate 40 through the second crankshaft connecting rod assembly 43, so that it can smoothly rotate along the hinge point. Through this design, it can be ensured that the third partition plate 40 can quickly and stably form a protection structure when the user is convenient.

[0057] Specifically, the second driving cylinder 42 can be an electric cylinder, a hydraulic cylinder or other suitable driving device. The second crankshaft connecting rod assembly 43 includes a plurality of connecting rods and hinge points, which can convert the linear motion of the driving cylinder into the rotational motion of the partition plate. For example, the telescopic end of the second driving cylinder 42 is connected to a connecting rod of the second crankshaft connecting rod assembly 43 through a hinge point, and the other end of the connecting rod is connected to the third partition plate 40 through another hinge point. Therefore, when the second driving cylinder 42 is telescopic, the connecting rod drives the third partition plate 40 to rotate, forming the required C-shaped protective structure.

[0058] The above technical means solve the problem that the nursing bed in the prior art lacks an effective protective structure when the user is relieving themselves. Compared with the traditional nursing bed, the design of the present application can better protect the privacy of the user, avoid the leakage of excrement, and improve the comfort and safety of the user.

[0059] As a specific implementation of the back-lifting driving unit in this application, refer to Figure 1 , Figure 2 as well as Figure 4 The back-lifting driving part is hinged to the first driving cylinder 32 of the bed frame 10, and the output end of the first driving cylinder 32 is hinged with a first crankshaft connecting rod assembly 33 for driving the second partition plate 30 in the middle position to rotate.

[0060] The design of the back-lifting drive unit is intended to solve many problems that exist in the process of adjusting the patient's position in traditional nursing beds. First, through the hinge connection between the first drive cylinder 32 and the bed frame 10, the second partition plate 30 can be accurately controlled so that it can be dynamically adjusted according to the patient's position requirements. Specifically, the output end of the first drive cylinder 32 is connected to the second partition plate 30 through the first crankshaft connecting rod assembly 33. When the cylinder is extended and retracted, it drives the second partition plate 30 to rotate around the hinge point, thereby adjusting the angle of the back support area. This design not only improves the patient's comfort during use, but also effectively avoids side leakage or contamination problems caused by improper position adjustment.

[0061] The first drive cylinder 32 can be implemented in various ways, for example, an electric cylinder or a hydraulic cylinder can be used to ensure stability and reliability in different usage scenarios. As a preferred embodiment, the electric cylinder has the advantages of high control accuracy and fast response speed, which is suitable for the use of nursing beds that require frequent adjustments. The hydraulic cylinder has a large thrust and a long service life, which is suitable for situations where a large load needs to be borne. In addition, the design of the first crankshaft connecting rod assembly 33 can be optimized according to specific needs to ensure its stability and reliability during the transmission process.

[0062] This application solves the shortcomings of traditional nursing beds in terms of body position adjustment by introducing a back-lifting drive unit, significantly improving the comfort of patients and the convenience of nursing staff. Compared with the prior art, the technical solution of this application not only realizes the dynamic adjustment of the back support area, but also avoids side leakage and contamination problems through precise control, providing a more scientific and humane nursing solution for long-term bedridden patients.

[0063] As a specific implementation of the leg support driving unit in this application, refer to Figure 1 , Figure 2 as well as Figure 4 The leg support driving unit includes a third driving cylinder 52 hinged to the bed frame 10, and the telescopic end of the third driving cylinder 52 is hinged with a third crankshaft connecting rod assembly 53. The end of the third crankshaft connecting rod assembly 53 away from the third driving cylinder 52 has a supporting frame for simultaneously supporting three fourth partition boards 50.

[0064] Technical understanding: The leg support drive unit realizes the synchronous drive of the fourth partition plate 50 through the cooperation of the third drive cylinder 52 and the third crankshaft connecting rod assembly 53. Specifically, the telescopic action of the third drive cylinder 52 is transmitted to the support frame through the third crankshaft connecting rod assembly 53, thereby driving the three fourth partition plates 50 to rotate downward along the hinge point. This technical solution solves the problem of synchronous drive of the leg support area and ensures that the nursing bed can form a stable C-shaped protective structure during the adjustment process.

[0065] The third driving cylinder 52 can be driven by conventional hydraulic or pneumatic means, and the third crankshaft connecting rod assembly 53 can be designed as a single connecting rod or a multi-connecting rod structure according to actual needs. The support frame can be customized according to the size and shape of the fourth partition plate 50 to ensure that it can provide sufficient support force and stability. For example, the support frame can be made of lightweight and high-strength materials, such as aluminum alloy or carbon fiber, to reduce the overall weight while ensuring structural strength.

[0066] Through this technical solution, the present application realizes effective control of the leg support area, and solves the problem that the leg support area cannot be adjusted synchronously in the prior art. Compared with the prior art, the technical solution of the present application has the following advantages: First, through the cooperation of the third drive cylinder 52 and the third crankshaft connecting rod assembly 53, the synchronous driving of the three fourth partition plates 50 is realized, ensuring the stability and reliability during the adjustment process; secondly, the design of the support frame enables the fourth partition plate 50 to form a C-shaped protective structure, which improves the comfort and safety of the patient during the nursing process; finally, the solution has a simple structure and is easy to implement, which helps to reduce manufacturing costs and maintenance difficulties.

[0067] As another preferred embodiment of the present application, the present application further proposes to include a defecation control switch and a controller. The defecation control switch is electrically connected to the controller to control the back-lifting drive unit, the toilet protection drive unit, and the leg support drive unit through the controller to start driving the first partition plate 20, the second partition plate 30, the third partition plate 40, and the fourth partition plate 50 to the specified position.
