Description

Technical Field

[0001] The present invention relates to the technical field of nursing beds, and particularly to a rehabilitation training nursing bed with a massage function. Background Art

[0002] In recent years, with the continuous progress of spinal curvature correction surgery technology, more and more patients have restored the normal physiological curvature of the spine through surgery. However, the rehabilitation process of postoperative patients still faces many challenges. Especially for patients who need to stay in bed for a long time, the rehabilitation effect of their spine is affected by various factors. In the prior art, patients usually need to stay in bed for a long time after surgery to promote the healing of the spine. However, the design of traditional nursing beds does not fully consider the special needs of postoperative patients.

[0003] When a patient lies on a nursing bed, due to the action of gravity, the patient's spine still bears downward pressure. This continuous pressure may not only hinder the healing of the spine but also easily cause discomfort symptoms such as back pain and muscle stiffness in the patient, thus delaying the rehabilitation process. In addition, the existing nursing beds can only manually adjust the overall undulation degree of the mattress. Although they provide a certain basic support function, their design is usually not optimized for the spinal rehabilitation of postoperative patients. For example, these nursing beds are difficult to dynamically adjust the support strength and position according to the personalized needs of patients, cannot effectively relieve the tension of the muscles around the spine, and are not conducive to promoting blood circulation and muscle relaxation. This not only reduces the comfort of patients but also may have an adverse impact on the rehabilitation effect of the spine. Summary of the Invention

Detailed implementation manners

[0037] The following describes the implementation manners of the present invention with reference to the drawings.

[0038] The present invention aims to solve the problem that the spine of postoperative patients is continuously under improper pressure during long-term bed rest, and designs a nursing bed that can automatically adapt to the curvature of the spine. This nursing bed can fix the natural curvature of the spine, ensure that the patient maintains the correct rehabilitation posture, meet the key needs of postoperative recovery, and its unique modular adaptive structure allows users to adjust the support position according to their own spinal curvature, thus significantly improving the rehabilitation effect.

[0039] Example 1: A nursing bed for rehabilitation training with a massage function. Please refer to Figures 1-6 As shown in the figure, it includes: a bed frame 1, and a bed board 2 is arranged on the bed frame 1; a protective shell 3, fixedly connected to the bed board 2, and a first oil storage shell 4 evenly distributed is fixedly connected to the protective shell 3. The first oil storage shell 4 is hermetically slidably connected with a first seal 5. A first spring in contact with the adjacent first seal 5 is arranged in the first oil storage shell 4. The upper side of the first seal 5 is fixedly connected with a support shell 6. A connecting member 7 is fixedly connected between two adjacent support shells 6. The connecting member 7 is an elastic band. A limiting component is arranged in the first oil storage shell 4, and the limiting component is used to limit the positions of all the first seals 5 in the adjacent first oil storage shells 4 after all the support shells 6 are attached to the patient's back; a plurality of massage components are all arranged on the protective shell 3 and are used to perform point massage on the patient.

[0040] In the above solution, lower body exercise equipment (not shown in the figure) can be installed on the bed frame 1. The bed frame 1 can be rotatably connected to the bed board 2. A hydraulic push rod (not shown in the figure) can be installed between the bed frame 1 and the bed board 2. The hydraulic push rod is used to drive the bed frame 1 to rotate on the bed board 2. When the patient needs rehabilitation training, the hydraulic push rod pushes the bed frame 1 upward to convert the patient from a lying position to a standing position (before this action is completed, the lower body of the patient has been fixed to the lower body exercise equipment). After the patient's posture is converted, the lower body exercise equipment drives the lower body of the patient to train [the spinal cord is located inside the spine and is responsible for transmitting the movement instructions sent by the brain to the lower limb muscles, and at the same time, it also transmits the sensory information (such as touch and pain) of the lower limbs back to the brain. Therefore, when performing lower body rehabilitation training, it is actually exercising these muscle groups controlled by the spinal cord]. When adaptively supporting the patient's spine, by evenly distributing the contact between the support shells 6 and different positions of the patient's back, the undulations of the support shells 6 evenly distributed to the patient conform to the undulations of the patient's spine, reducing the pressure on the patient's spine while supporting the patient's spine.

[0041] Please refer to Figures 5-8As shown, the limiting component includes: a first plugging member 8, rotatably connected to the lower side of the first sealing member 5. Liquid through holes are provided on both the lower side of the first sealing member 5 and the first plugging member 8, and the liquid through holes on the lower side of the first sealing member 5 and the first plugging member 8 are interconnected. The first plugging member 8 is used to plug the liquid through hole on the first sealing member 5; a rotating rod 9, sealingly and slidably connected to the first plugging member 8; a rotating ring 10, sealingly and rotatably connected to the first oil storage shell 4. The rotating ring 10 is fixedly connected to the rotating rod 9. A driving member 11 is provided on the protective shell 3, and a moving member 12 is fixedly connected to the telescopic end of the driving member 11. An L-shaped frame 13 is fixedly connected to the rotating rod 9, and all the L-shaped frames 13 are slidably connected to the moving member 12. The support shell 6 is rotatably connected to mirror-image distributed support frames 14. By the contact of the support frames 14 with the patient's back, the lying posture of the patient is restricted. A flexible pad for increasing the comfort of the patient is placed on the upper side of the bed frame 1, and this flexible pad is located above all the support frames 14 and all the support shells 6.

[0042] In the above solution, hydraulic oil is stored in the first oil storage shell 4. The first plugging member 8 is a circular plate. When the first plugging member 8 plugs the liquid through hole on the first sealing member 5, the first sealing member 5 remains fixed. The cross-section of the rotating rod 9 is oval, and the rotating rod 9 is used to drive the first plugging member 8 to rotate during the up and down movement.

[0043] Please refer to Figures 5-8 As shown, the support shell 6 is fixedly connected to mirror-image distributed material storage shells 15. An extrusion member 16 is slidably connected to the material storage shell 15. An elastic liquid bladder in contact with the extrusion member 16 is fixedly connected inside the material storage shell 15. The protective shell 3 is fixedly connected to second oil storage shells 17 that are the same in number as the support shells 6 and are respectively located below adjacent support shells 6. A first sliding plate 18 is sealingly and slidably connected inside the second oil storage shell 17. The L-shaped frame 13 passes through the first sliding plate 18 and is sealingly and slidably connected to it. A second spring in contact with the first sliding plate 18 is provided inside the second oil storage shell 17. A liquid through pipe is fixedly connected and communicated between the elastic liquid bladder inside the material storage shell 15 and the adjacent second oil storage shell 17. A second plugging member 19 is rotatably connected inside the second oil storage shell 17. The second plugging member 19 is fixedly connected to the adjacent L-shaped frame 13, and the second plugging member 19 is used to plug the communication position between the second oil storage shell 17 and the adjacent liquid through pipe.

[0044] In the above solution, the centers of the circles where the material storage shell 15 and the adjacent extrusion member 16 are located are on the rotation axis of the adjacent support frame 14. Hydraulic oil is stored between the elastic liquid bladder inside the material storage shell 15, the adjacent liquid through pipe, and the upper side inside the second oil storage shell 17 and the first sliding plate 18. When the pressure in the adjacent liquid through pipe inside the material storage shell 15 increases, the pressure on the upper side inside the second oil storage shell 17 also increases. During the process of the pressure increase inside the second oil storage shell 17, the adjacent first sliding plate 18 will be squeezed downward.

[0045] Please refer to Figure 5 and Figures 9-12As shown in the figure, the massage component includes: third oil storage shells 20 that are mirror - distributed, support frames 14 that are respectively fixedly connected to a set of adjacent support shells 6 and are mirror - distributed, a second seal 21 that is hermetically and slidably connected in the third oil storage shell 20, a spring pull rod that is fixedly connected in the third oil storage shell 20 and is fixedly connected to the second seal 21, second sliding plates 22 that are slidably connected in the support frames 14 that are mirror - distributed on adjacent support shells 6, the second sliding plates 22 are fixedly connected to adjacent second seals 21, the second sliding plates 22 are fixedly connected with a plurality of massage parts 23, and support components are arranged in the support frames 14 that are mirror - distributed on adjacent support shells 6. The support components are used to temporarily support the patient's body after the operation of massaging the patient is completed.

[0046] In the above - mentioned solution, the number of massage components can be adjusted according to the actual situation. Hydraulic oil is stored between the lower side of the second seal 21 and the adjacent third oil storage shell 20. When the pressure in the lower side of the third oil storage shell 20 increases, the second seal 21 moves upward. Through the contact between the massage parts 23 and the patient, it simulates the massage of the patient by fingers or knuckles (this technique is called the point - pressing method in traditional Chinese medicine). During normal use, medical staff will connect the pressure - control device to the lower sides of the two third oil storage shells 20 to control the pressure in the two third oil storage shells 20.

[0047] Working principle: When a patient after spinal surgery needs rehabilitation treatment, medical staff help the patient to the bed board 2, and then let the patient lie down on the bed board 2 slowly. During the process of the patient lying down, the patient's back first presses all the support frames 14 downward, causing the support frames 14 on the same side to swing away from the patient. During the swinging process of the support frames 14, the squeezing parts 16 are driven to slide along the adjacent material - containing shells 15 and squeeze the adjacent elastic liquid sacs therein. After the elastic liquid sacs in the material - containing shells 15 are squeezed, the hydraulic oil therein enters the adjacent second oil storage shell 17 through the adjacent liquid - passing pipes, thereby increasing the pressure in the second oil storage shell 17, causing the first sliding plate 18 to squeeze downward while squeezing the adjacent second spring.

[0048] During the process of the patient lying down, the patient's back contacts all the support shells 6, thus squeezing all the support shells 6 to move downward. During the process of the support shells 6 moving downward, the first seal 5 slides downward along the adjacent first oil storage shell 4 and squeezes the adjacent first spring. During the movement of the first seal 5, the adjacent first plugging parts 8 are driven to move synchronously. At this time, the hydraulic oil in the first seal 5 flows through the first plugging parts 8 and the liquid - passing holes on the adjacent first seal 5.

[0049] After the patient lies down completely, all the support shells 6 move adaptively according to the shape of the patient's spine (when all the support shells 6 change their heights according to the shape of the patient's spine, they stretch the adjacent connecting pieces 7, deforming the connecting pieces 7 and making them fit the patient's spine), so as to achieve the effect of adaptive support according to the shape of the patient's spine. At this time, the telescopic end of the driving part 11 is extended by operating the control terminal, and the telescopic end of the driving part 11 drives the moving part 12 to move to the left, so that the moving part 12 drags the front sides of all the L-shaped frames 13 to the left, so that all the L-shaped frames 13 drive the adjacent second blocking parts 19, the adjacent rotating rings 10, the adjacent rotating rods 9 and the adjacent first blocking parts 8 to rotate synchronously. During the rotation of the first blocking part 8, the liquid passing holes on the adjacent first sealing part 5 are blocked, so that the first sealing part 5 will not slide randomly in the adjacent first oil storage shell 4. During the rotation of the second blocking part 19, the connecting part between the adjacent second oil storage shell 17 and the adjacent liquid passing pipe is blocked, so that the first sliding plate 18 will not slide randomly in the adjacent second oil storage shell 17. Through the above process, the positions of all the support shells 6 and all the support frames 14 are fixed. During this process, by fitting all the support frames 14 to the parts of the patient's back away from the spine, the state of the patient during the rehabilitation training is restricted, thereby reducing the additional pressure or injury caused to the spine.

[0050] After the patient lies down completely and the patient's spine has been supported, the medical staff fix the patient to the bed frame 1 through straps, and then the patient or the medical staff squeeze the bed board 2 upward through the hydraulic push rod on the bed frame 1, so that the bed board 2 flips upward to find a suitable training angle, and the patient can use the lower body exercise equipment for rehabilitation training. After spinal surgery, the surrounding muscles may be weakened due to the surgery or postoperative fixation. Therefore, the lower body exercise equipment helps to accelerate the recovery of physical functions, especially the reconstruction of muscle strength and flexibility.

[0051] When the patient needs to rest, the hydraulic push rod on the bed frame 1 squeezes the bed board 2 upward, so that the bed board 2 swings downward to reset, so as to return to Figure 1 the state.

[0052] When it is necessary to massage the patient, the medical staff connect the pressure control device to the third oil storage shell 20. Now, the movement process of the parts in one of the third oil storage shells 20 will be described: when massaging the patient, liquid is injected into the third oil storage shell 20 through the pressure control device, increasing the pressure between the lower side of the second sealing part 21 and the inside of the third oil storage shell 20, so that the second sealing part 21 moves toward the patient's side and stretches the adjacent spring pull rod. During the movement of the second sealing part 21, it drives the second sliding plate 22 and all the massage parts 23 thereon to move toward the patient's back ( Figure 4The massage position of the massage part 23 is exactly the latissimus dorsi muscle of the patient. Through the contact between the massage part 23 and the patient, the latissimus dorsi muscle of the patient is massaged by pressing, improving the blood circulation of the latissimus dorsi muscle part of the patient, thereby reducing muscle tension, decreasing the stiffness of the muscle, and accelerating postoperative recovery.

[0053] After the massage part 23 finishes pressing on the patient's back, the pressure control device reduces the pressure in the third oil storage shell 20. Under the action of the spring pull rod and the reduced pressure in the third oil storage shell 20, the second sealing part 21 drives the adjacent massage part 23 to move to the side away from the patient through the second sliding plate 22, so that the massage part 23 no longer contacts the patient's back, and thus the massage of the patient is completed.

[0054] When the patient no longer needs to rely on this device for rehabilitation training, the medical staff assist the patient to move out of the bed board 2. At this time, the telescopic end of the driving part 11 is controlled by the control terminal to reset to the right. During the reset process of the telescopic end of the driving part 11, the moving part 12 moves synchronously. The moving part 12 drags the front sides of all the L-shaped frames 13 to the right until all the L-shaped frames 13 are in the Figure 4 and Figure 5 state. During the process of the front side of the L-shaped frame 13 being dragged to the right, it swings and resets to the right. During the swinging and reset process of the L-shaped frame 13, it drives the adjacent second blocking part 19 and the adjacent first blocking part 8 to reset. During the rotation process of the second blocking part 19, it no longer blocks the communication part between the adjacent second oil storage shell 17 and the adjacent liquid passing pipe. During the rotation process of the first blocking part 8, it no longer blocks the liquid passing holes on the adjacent first sealing part 5.

[0055] When the patient leaves, all the support shells 6 and all the support frames 14 are no longer oppressed. The first sliding plate 18 moves upward to reset under the action of the adjacent second spring, so that the hydraulic oil between the upper side of the first sliding plate 18 and the adjacent second oil storage shell 17 flows into the adjacent two elastic liquid sacs through the adjacent liquid passing pipes respectively. After the pressure in the elastic liquid sacs increases, it squeezes the adjacent extrusion parts 16, so that the extrusion parts 16 drive the adjacent support frames 14 to swing upward and reset along the adjacent support shells 6. The first sealing part 5 moves upward to reset under the action of the adjacent first spring. During the process of the first sealing part 5 moving and resetting, it drives the support shell 6 to move and reset. During the process of the support shell 6 moving and resetting, the connecting parts 7 are reset successively. When the above parts move to the Figure 4 state, it is the basic state (that is, the state when the patient is not lying down).

[0056] Patients who stay in bed for a long time (such as during the postoperative recovery period) are prone to various skin problems due to long-term contact between the body and the bed surface. These problems include pressure ulcers (bedsores), which are ulcers caused by long-term compression of the skin and subcutaneous tissues, leading to poor blood circulation and insufficient nutrient supply. In addition, long-term compression may also cause blockage of skin pores, increasing the risk of skin problems such as acne. To solve the above problems, the present invention can temporarily separate the patient's local area from the bed surface while massaging the patient, reducing the local pressure on the patient while still being able to massage the patient.

[0057] Embodiment 2: On the basis of Embodiment 1, please refer to Figures 10-12 As shown, the support assembly includes: a third sliding plate 24, which is slidably connected to the third oil storage shell 20. A third spring is fixedly connected between the third sliding plate 24 and the adjacent second seal 21. The third oil storage shell 20 is slidably connected with a fixed cylinder 26 fixedly connected to the adjacent third sliding plate 24. The fixed cylinder 26 penetrates through the adjacent support frame 14 and is slidably connected thereto. The fixed cylinder 26 is used to limit the second seal 21. The fixed cylinder 26 is fixedly connected with a connecting column 27. The upper end of the connecting column 27 is fixedly connected with a fourth sliding plate 28 that slides along the support frame 14. All the massage members 23 on the same second sliding plate 22 pass through the fourth sliding plate 28 and slide along it. The third oil storage shell 20 is fixedly connected with a fixing ring 25 for limiting the adjacent third sliding plate 24. A deceleration hole is provided on the upper side of the third oil storage shell 20 to reduce the moving speed of the adjacent third sliding plate 24.

[0058] In the above solution, when the third sliding plate 24 drives the fixed cylinder 26 to move upward, the fourth sliding plate 28 contacts the patient's back, temporarily separating the patient's back from the bed board 2, achieving the effect of reducing the local pressure on the patient. And through the blockage of the fixing ring 25 on the lower side of the third sliding plate 24, the fixed cylinder 26 can be reset to the initial state each time, and at this time, the fixing ring 25 no longer applies an extrusion force to the adjacent third spring, thereby reducing the fatigue degree of the third spring between the fixed cylinder 26 and the adjacent second seal 21.

[0059] Working principle: When massaging the patient, the pressure at the lower side of the third oil storage shell 20 is increased through the pressure control device, causing the second seal 21 to move towards the patient's back (at this time, the telescopic part of the spring pull rod is stretched). During the movement of the second seal 21, the adjacent third sliding plate 24 is driven to move synchronously through the adjacent third spring. At this time, the oil injection speed in the third oil storage shell 20 is greater than the gas discharge speed on its upper side. Therefore, the moving speed of the third sliding plate 24 is slower than that of the adjacent second seal 21, and the third spring on the lower side of the third sliding plate 24 is compressed.

[0060] After the second seal 21 drives the second sliding plate 22 to move until the massage member 23 contacts the patient, the point massage on the patient is realized. At this time, the third sliding plate 24 drives the fixed cylinder 26, the connecting column 27 and the fourth sliding plate 28 to move upward slowly under the action of the adjacent third spring. When the fourth sliding plate 28 moves to fit the patient's back, after the upper side of the fourth sliding plate 28 is flush with the upper sides of all the massage members 23 on the adjacent second sliding plate 22, the pressure control device reduces the pressure in the third oil storage shell 20, so that the second seal 21 slides downward prior to the adjacent third sliding plate 24. During the slow reset process of the fourth sliding plate 28, the latissimus dorsi muscle of the patient is briefly supported, thereby reducing the pressure borne by the patient's back.

[0061] After the second seal 21 slides to Figure 10 the state in Figure 10 under the action of the third tension spring on the upper side of the second seal 21, the third sliding plate 24 slowly moves to

[0062] the state in That is, the reset action of the above parts is completed. When massage is required again, the above process can be repeated. Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that these embodiments can be changed without departing from the principle and spirit of the present invention.
