Abstract
Description
Technical Field
[0001] The invention relates to a multifunctional rotating medical nursing bed, which is used for facilitating the nursing work of patients. Background Art
[0002] Current medical care beds have more and more functions. The conventional structure mainly has a back-lifting device, which uses a push rod or a push rod to tilt one end of the mattress upward to achieve the effect of getting up. However, even if the patient sits up on the medical bed, when the patient needs to get out of bed, the nurse needs to use a lot of force to help the patient out of the medical bed, which is inconvenient for the patient to get out of bed. A multifunctional medical bed is disclosed in the public document with application number 201921869877.9. The nursing bed can have two actions: 1. The servo motor drives the screw rod to rotate, and the slider on the screw rod moves horizontally along the screw rod 13 toward the third mattress, so that the back-lifting push rod pushes the first mattress to tilt and flip (such as Figure 4); 2. The driving motor is started, driving the transmission gear to rotate, and the transmission gear drives the rack to move horizontally, so that the second mattress moves along the bed frame 1 toward the third mattress, and the third mattress is pushed to move out of the bed frame; after the third mattress moves out of the bed frame, it turns downward 90 degrees due to its own gravity. At this time, the patient's legs are bent (sitting position) as the third mattress turns downward. Since the second mattress starts to rotate after it moves to the original position of the third mattress, the patient avoids the handrail when rotating, so that the patient does not need to lower the handrail when getting out of bed, which is convenient for use. However, this type of nursing bed has the following unreasonable aspects: 1. When the nursing bed rotates, a transmission gear is required to drive the rack to move horizontally, that is, the end plate on one side of the nursing bed needs to be disassembled to achieve this, which makes each rotation operation very cumbersome; 2. After the third mattress is moved out of the bed frame, it flips downward 90 degrees due to its own gravity, and the patient is in a sitting position. However, when resetting, the third mattress flipped 90 degrees will affect the horizontal movement and resetting of the mattress. Therefore, the third mattress needs to be lifted to a horizontal position. If the patient sits on the bed to reposition, it is very difficult to operate. Not only must the weight of the third mattress itself be overcome, but also the weight of the patient's legs must be overcome. It is difficult for general nursing staff to operate alone. If the patient does not sit on the nursing bed to reposition, then although it is relatively easier to lift the third mattress, after the nursing bed is repositioned to a horizontal position, the patient It is difficult to get into bed, and the original functional effect of the rotating bed is lost; 3. When this nursing bed is in use, the patient avoids the handrail fence when rotating, so that the patient does not need to lower the handrail fence when getting out of bed, which is convenient to use. However, during the rotation process, the first mattress always keeps the patient's back in a sitting position, and the patient avoids opening the handrail fence during rotation. The patient has no parts to hold, and the patient is in a tilted state and is prone to sliding down, which poses a certain risk; 4. During the horizontal movement of the second mattress of this nursing bed, the rotating shaft and the rotating motor need to slide horizontally on the supporting platform. These rotating parts are prone to wear when moving horizontally, resulting in errors in matching, and the assembly accuracy requirements are too high. 5. This nursing bed cannot help patients turn over, and patients who stay in bed for a long time are prone to pressure sores. Summary of the invention

In this way, the headboard guardrail is always in a vertical state, which is convenient for patient care.
[0012] After adopting the above technical solution, the effect of the present invention is that the nursing bed can realize turning over, back lifting, leg lifting and rotation operations;
[0013] 1. The action and principle of the turning over operation are as follows: since a swinging force device for driving the swinging bed frame to swing and tilt around a swinging axis is provided between the bed body and the swinging bed frame, the swinging bed frame will swing and tilt around the swinging axis, and since the swinging bed frame is located in the middle of the bed body, the bed board assembly will be driven to deflect during the tilting process of the swinging bed frame, and since the foot support structure also supports the first calf support bed board and the third calf support bed board, and the head support structure supports the bottom of the first bed back board and the third bed back board, therefore, the bottom of the first bed back board and the third bed back board ... The first calf support bed board and the third calf support bed board will not turn over, which is convenient for supporting the patient, while the first middle bed board, the second thigh support bed board, the second calf support bed board, and the second bed back board assembly will deflect around the first type of hinge axis, the second type of hinge axis, the third type of hinge axis, and the fourth type of hinge axis and lift one side, so as to turn the patient onto the first bed back board, the first middle bed board, the first thigh bed back board, the first calf bed board, or onto the third bed back board, the third middle bed board, the third thigh bed back board, and the third calf bed board, so as to realize turning over to the left or right;
[0014] 2. The actions and principles of back and leg lifting are as follows: wherein, the first bed backboard and the third bed backboard are both eccentrically mounted on the supporting bed frame through a four-bar linkage mechanism, and a backboard flipping power device is provided between the supporting bed frame and the second bed backboard, so that the backboard flipping power device can flip the second bed backboard and lift it upward. At this time, since the first bed backboard, the second bed backboard and the third bed backboard are arranged along the width direction and are hinged in sequence through the fourth type of hinge shaft, during the lifting action, the first bed backboard, the second bed backboard and the third bed backboard will be lifted as a whole bed backboard; similarly, when performing the leg lifting action, a leg board flipping power device is provided between the supporting bed frame and the second calf supporting bed board, and the leg board flipping power device drives the second calf supporting bed board to lift upward, and the entire calf supporting bed board assembly is also lifted as a whole, thereby realizing the patient's leg lifting;
[0015] 3. The action and principle of rotation are as follows. First, lift the calf support bed board assembly and the bed back board assembly respectively to separate them from the support of the head support structure and the foot support structure. This will not only not hinder the rotation, but also the patient is in a state of raising his back and calf, and will not slide even if he does not grasp the guardrail, which is safer. The rotating power device drives the rotating table of the rotating table to rotate 90°, and the rotating table will drive the supporting bed frame to rotate, and the supporting bed frame will drive the bed board assembly to rotate as a whole. After rotating 90°, the calf support bed board assembly is driven by the leg board flipping power device to flip downward, which makes it convenient for the patient to get out of bed. The multifunctional rotating medical nursing bed can not only realize the patient's turning over, lifting his back, lifting his legs, and rotating to get out of bed, but also has a very compact and reasonable structure. The various actions are independent of each other and do not interfere with each other. At the same time, the safety of the entire nursing bed is higher. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] like Figure 7As shown, the connecting cross bar 187 includes a first cross bar segment and a second cross bar segment, and the first cross bar segment and the second cross bar segment are connected by a U-shaped connecting seat 188. The backboard flipping linear motor 25 is located in the U-shaped groove of the U-shaped connecting seat 188. The upper end surfaces of the two supporting longitudinal beams 181 are provided with a receiving groove 189. The first cross bar segment and the second cross bar segment are provided with a reinforcing support seat 27 located in the receiving groove 189. Since the reinforcing support seat 27 is provided on the connecting cross bar 187, the reinforcing support seat 27 can be sunk into the receiving groove 189, so that the second bed backboard 72 can be better leveled to make it flush with other bed boards.
[0040] In this embodiment, Figure 5 and Figure 7As shown, the guardrails include two head guardrails 8 and two foot guardrails 9, the head guardrails 8 are respectively hinged to the two sides of the first bed backboard 71 and the third bed backboard 73 and are symmetrically arranged, the foot guardrails 9 are respectively hinged to the two sides of the first thigh support bed board 51 and the third thigh support bed board 53 and are symmetrically arranged, each head guardrail 8 is also provided with a first hinged connecting rod seat extending downward, the lateral sides of the second bed backboard 72 are respectively fixed with backboard hinged connecting rod seats, and the first hinged connecting rod seat on each head guardrail 8 is respectively hinged to the backboard hinged connecting rod seat on the corresponding side with a first lower hinged connecting rod seat. The first lower hinged connecting rod is respectively located below the first bed backboard 71 and the third bed backboard 73. A second hinged connecting rod seat 91 extending downward is also provided on each bed end guardrail 9. The second thigh supporting bed board 52 is respectively fixed with a leg board hinged connecting rod seat on both sides of the lateral direction. The second hinged connecting rod seat 91 on each bed end guardrail 9 is respectively hinged with a second lower hinged connecting rod 92 between the leg board hinged connecting rod seat on the corresponding side. The second lower hinged connecting rod 92 is respectively located below the first thigh supporting bed board 51 and the third thigh supporting bed board 53. When turning over, the deflection force device 22 (Preferably a yaw linear motor) drives the yaw bed frame to yaw to the left according to the patient's lying state. At this time, when the yaw bed frame yaws, it will drive the support bed frame 18 to yaw. Since the first bed back board 71 and the first calf support bed board 41 are supported by the head support structure 102 and the foot support structure 101 respectively, when deflecting to the left, the first bed back board 71, the first middle bed board 61, the first thigh support bed board 51, and the first calf support bed board 41 on the left side are all in a horizontal state, and the right side of the support bed frame 18 is raised, and the corresponding second bed back board 72, the second middle bed board 62, and the second The thigh support bed board 52 and the second calf support bed board 42 are tilted and the right side is raised, and the tilted high end of the second bed back board 72 will pull the first lower hinged connecting rod to tilt it. Of course, the first lower hinged connecting rod will also pull the third bed back board 73 to slightly translate horizontally for a short distance, and the third bed back board 73 will also tilt. Since the bedside guardrail 8 is hinged on the third bed back board 73 and is also hinged with the first lower hinged connecting rod, even if the first lower hinged connecting rod and the third bed back board 73 are tilted, it will not affect the state of the bedside guardrail 8. In this way, the bedside guardrail 8 is always in a vertical state, which can facilitate patient care. Similarly, the bed guardrail 9 will also be in a vertical state, which can better protect the patient.
[0041] The rotation, turning over, leg lifting and back lifting functions of the multifunctional rotating medical care bed in the present invention are all independent of each other and are not affected. Before starting the rotation function, the leg lifting and back lifting operations are performed first, so that the bed back board assembly 7 and the calf support bed board assembly 4 are both lifted up and away from the bed head support mechanism and the bed support structure. In this way, the support bed frame 18 is rotated while ensuring the safety of the patient. The support bed frame 18 drives the bed board assembly to rotate 90°, and then the calf support bed board is flipped downward, thereby facilitating the patient to get out of bed. During the entire process of getting out of bed, the guardrails are on both sides of the bed board assembly, which is convenient for the patient to hold and leverage.
[0042] The above-described embodiments are merely descriptions of preferred implementations of the present invention and are not intended to limit the scope of the present invention. Various modifications and alterations to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the scope of protection defined by the claims of the present invention.
