[0002] In the field of medical care, patients who are bedridden for a long time face many health risks and nursing difficulties. For critically ill patients, postoperative rehabilitators, or those with neurological diseases and other conditions that limit limb movement, turning over regularly is a key nursing measure to prevent pressure ulcers, promote blood circulation, improve pulmonary ventilation function, and enhance patient comfort.

[0003] According to Chinese Patent Publication No. CN110856681A, this patent provides a hospital bed for assisting a patient to turn over and transfer automatically, including a bed frame and roller mechanisms symmetrically arranged on the left and right sides of the bed frame; the roller mechanism includes: a power roller installed on the longitudinal beam of the bed frame, and swing plates symmetrically installed on the cross beam of the bed frame front and back; the swing plate includes a first mounting end, a second mounting end, and a third mounting end, and the three mounting ends form a triangle. The swing plate is rotatably connected to the cross beam of the bed frame through the first mounting end. By rotating the rocker, the lead screw is driven to rotate and screw into or out of the lead screw sleeve, so as to lengthen or shorten the total length of the lead screw and the lead screw sleeve, and further pull the longitudinal tube to move. The movement of the longitudinal tube causes the swing rod to swing, and the height of the idle roller arranged on the swing rod can be adjusted; by adjusting the different heights of the idle rollers on both sides of the bed frame and driving by the power roller, the automatic turning over of the patient lying on the transmission cloth can be realized.

[0004] However, when facing patients with mental illnesses or obesity, the lying postures of the patients are often uncontrollable. When medical staff need to correct the postures of such patients before turning over, the non - cooperation and heavy weight of the patients will make the preliminary work extremely difficult. In the prior art, using rollers and a transmission cloth can only turn the patient to one side. At this time, the patient's body position shifts to one side of the hospital bed and cannot be centered, which will cause discomfort during rest, easy to fall off the hospital bed, and excessive extrusion of one side of the hospital bed, resulting in damage to the bed body. Therefore, a hoisting turning assistance device for a hospital bed is proposed to solve the above - mentioned problems. Summary of the Invention

[0016] (III) Beneficial effects Compared with the prior art, the present invention provides a hoisting and turning assistance device for a hospital bed, having the following beneficial effects: 1. The hoisting and turning assistance device for the hospital bed is used to solve the problem of patient posture correction. For patients with mental illness, obesity, etc. who do not cooperate with turning over, two symmetrically arranged correction parts can forcibly correct their posture before turning over. The first motor drives the rope winding cylinder to wind the pulling rope, driving the binding belt to pull the patient's torso and legs, so that the patient lies flat on the bed body, avoiding the difficulty of correction caused by the patient's non - cooperation and large body weight, laying a foundation for the subsequent turning - over operation. The control part can work synchronously with the correction part. While correcting the patient's posture, through the cooperation of the reclining part, the hospital bed is restored to the horizontal position for CPR care, preventing the patient from sliding to the side of the bed and facilitating the CPR care and examination of the patient.

[0017] 2. The hoisting and turning assistance device for the hospital bed is used to automatically help the patient turn over and reset. The turning - over part can automatically help the patient turn over and enable the patient to return to the middle of the bed. For example, the second motor drives the winding roller to wind the bed cloth to achieve the side - turning of the patient. After side - turning, the patient is dragged back to the middle of the bed body by the movement of the bed cloth, improving the comfort of the patient's rest, avoiding the patient falling off the hospital bed and excessive squeezing of one side of the bed body, resulting in bed body damage.

[0018] 3. The hoisting and turning assistance device for the hospital bed is used to improve the stability of the turning - over operation. The electric push rod of the adjustment part can push the Z - shaped arm to rise and fall, thereby adjusting the height of the tension roller, increasing the tension of the turning - over bed cloth, ensuring the stability of the bed cloth during the turning - over process, especially ensuring stable turning - over work even when facing patients with different body shapes.

[0019] 4. The hoisting and turning assistance device for the hospital bed is used to limit the turning - over angle of the patient to ensure safety. The baffle of the support part can limit the turning - over angle of the patient, playing a buffering and blocking role when the patient turns over, preventing excessive turning from causing human injury and component collision, improving the safety of the patient during turning over, and protecting the patient's limbs and equipment components.

[0020] 5. The hoisting and turning assistance device for the hospital bed is used to reduce the work pressure of medical staff. The automation function of the whole device reduces the pressure of medical staff against patients with mental illness and obesity, reduces the difficulty of turning over, makes the medical work easier to carry out, and improves the nursing efficiency.

[0026] In order to facilitate the adjustment of the patient's lying and sitting posture, the lying and sitting part 3 of this case includes a front bed board 31. The front bed board 31 is hinged to the bed body 1. Two triangular bodies 32 are symmetrically installed at the bottom of the front bed board 31. T-shaped grooves 33 are opened on the inclined surfaces of the two triangular bodies 32.

[0027] In order to restore the bed to a horizontal position for CPR nursing while correcting the patient's posture, the control unit 12 of this case includes two hanging plates 121, and the two hanging plates 121 are fixedly connected to the two sides of the bottom of the support plate 21. A worm 122 is rotatably connected between the two hanging plates 121, and both ends of the worm 122 and the ends of the two rotating shafts 24 are fixedly sleeved with pulleys, and a transmission belt 123 is transmission-connected between the two pulleys on the same side, and the side walls of the two hanging plates 121 are fixedly connected to beams 124, and the ends of the two beams 124 are fixedly connected to U-shaped hanging plates 125, and the two ear ends of the U-shaped hanging plates 125 are fixedly connected to the bottom of the bed body 1, and the bottom of the support plate 21 is fixedly connected to a hanging plate 2 126, and the hanging plate 2 126 and the U-shaped hanging plate 126 are connected to the U-shaped hanging plate 126. A rotating rod 127 is rotatably connected between the plates 125, and a thread is provided in the middle of the outer wall of the rotating rod 127. A worm gear 128 is fixedly sleeved at one end of the rotating rod 127, and the worm gear 128 is meshed with the worm 122. A control arm 129 is threadedly connected to the thread of the rotating rod 127, and both ends of the control arm 129 are respectively slidably sleeved on the two cross beams 124. The tops of both ends of the control arm 129 are fixedly connected with arm grooves 1210, and the inner walls of the two arm grooves 1210 are hinged with T-shaped arms 1211, and the two T-shaped arms 1211 are respectively slidably connected to the inner walls of the two T-shaped grooves 33. The correction part 2 is located on one side of the front bed board 31. There are two correction parts 2, and the other correction part 2 is located on one side of the bed body 1. The two correction parts 2 are symmetrically arranged with each other.

[0028] In this embodiment, in order to protect the instrument parts of the correction part 2, the tops of the two support plates 21 are fixedly connected with protective plates 4, each protective plate 4 is provided with two through holes 5, and the movable ends of the two pull ropes 26 in each correction part 2 are respectively movable through the two through holes 5 on the same side, and a head pad 6 is fixedly connected to one of the protective plates 4, and a bed frame 7 is installed on the side of the two support plates 21 away from each other, and support beams 13 are symmetrically installed between the bottoms of the two support plates 21, and the bottom of the bed body 1 is fixedly connected to the two support beams 13, and the bottom of the front bed board 31 is in contact with the two support beams 13. The support beam 13 is a T-shaped structure, and its convex end is used to install the turning part 8 and the adjustment part 9.

[0029] It is worth noting that in order to achieve the purpose of automatically turning the patient over and turning over and improve the nursing efficiency, the turning part 8 in this case includes two frames 81, and the two frames 81 are symmetrically installed on the top of the side support beam 13. The frames 81 are respectively fitted with the front bed board 31 and the side wall of the bed body 1. One of the frames 81 is fixedly installed with a second motor 82, and a winding roller 83 is rotatably connected between the two frames 81. One end of the winding roller 83 movably passes through the frame 81 and is fixedly connected to the output shaft of the second motor 82.

[0030] In order to further improve the stability of the turning operation, especially to ensure a stable turning operation even when facing patients with different body shapes, the adjusting part 9 of this case includes two L-shaped frames 91. The two L-shaped frames 91 are installed on both sides of the top of one side support beam 13 and are located on the side where the two frames 81 are far away from each other. The L-shaped frames 91 are respectively attached to the front bed board 31 and the side wall of the bed body 1. Electric push rods 92 are installed on both L-shaped frames 91. Slide holes 93 are opened on the outer walls of the two L-shaped frames 91. One end of a Z-shaped arm 94 is slidably connected to the inner wall of each of the two slide holes 93. The slide holes 93 limit the lifting movement of the Z-shaped arm 94 to prevent shaking and deviation. The other ends of the two Z-shaped arms 94 are respectively fixedly connected to the end parts of the inner rods of the two electric push rods 92. A tension roller 95 is rotatably connected between the sliding ends of the two Z-shaped arms 94. There are two turning parts 8 and two adjusting parts 9 respectively. The other turning part 8 and adjusting part 9 are installed on the top of the other support beam 13. The two turning parts 8 and adjusting parts 9 are symmetrically arranged with each other.

[0031] It is worth noting that in order to improve the safety of the patient during turning and further protect the patient's limbs from injury and the instrument parts from damage, the supporting part 10 of this case includes two support arms 101. Both support arms 101 are L-shaped structures. The two support arms 101 are respectively fixedly connected to the sides of the sliding ends of the two Z-shaped arms 94 on one side that are far away from each other. Support rods 102 are fixedly connected to the ends of the two support arms 101 that are close to each other. A baffle 103 is fixedly connected between the two support rods 102. There are two supporting parts 10. The other supporting part 10 is installed on the sliding ends of the two Z-shaped arms 94 on the other side. The two supporting parts 10 are symmetrically arranged with each other. The two ends of the bed cloth 11 are wound around the two winding rollers 83. The bed cloth 11 is used to press on the bedsheet without hindering the patient's rest. At the same time, the bed cloth 11 can also play a role in preventing pollution, avoiding the bedsheet being polluted by some physiological conditions of the patient. The bed cloth 11 also bypasses the outer walls of the two tension rollers 95 and is attached to the bed body 1 and the front bed board 31. The tension roller 95 is used to maintain the tension of the bed cloth 11 during winding and releasing, preventing it from being wrinkled and deformed due to stress.

[0032] Working principle: When adjusting the lying and sitting postures of the patient, the electric push rod 92 needs to be pushed to raise the Z-shaped arm 94, so that the tension roller 95 moves away from the front bed board 31 and the bed body 1, avoiding collisions when the front bed board 31 flips. The first motor 23 works to synchronously rotate the two side rotating shafts 24, driving the worm 122 to rotate synchronously through the transmission belt 123. At this time, the worm 122 drives the worm wheel 128 to rotate, prompting the rotating rod 127 to drive the control arm 129 to move towards the U-shaped hanging plate 125. This movement is a forward movement. At this time, the pull rope 26 will be released and extended synchronously. The cross beam 124 limits the movement of the control arm 129 to avoid shaking and deviation. The arm groove 1210 moves with the control arm 129, prompting the T-shaped arm 1211 to slide along the inner wall of the T-shaped groove 33, and at the same time performing a curvilinear movement through its own hinged method to adapt to the inclination angle of the triangular body 32, and then pushing the front bed board 31 to flip through the hinge on the bed body 1 to adjust the angle of the front bed board 31, lifting the patient from a lying position to a reclining position, and thus facilitating work such as examining, nursing, and feeding the patient.

[0033] When performing CPR examination and nursing on the patient, the patient leans on the inclined front bed board 31, and the four straps 27 are respectively tied to the patient's shoulders, armpits, and ankle parts. The first motor 23 drives the rope winding cylinder 25 to wind up the pull rope 26. The pull rope 26 slides along the through hole 5 and drives the strap 27 to pull the patient's torso and legs. Through a reasonable winding speed of the first motor 23, the control arm 129 moves synchronously in the reverse direction, regarded as a reset movement, so as to flip the front bed board 31 downward to reset to the CPR horizontal position. At the same time, the patient's armpit is subjected to a pulling force, forcibly correcting the patient to lie flat on the bed body 1, thus avoiding the non-cooperation of mental patients and the sliding and deviation of obese patients to the side of the bed on the hospital bed, ensuring that the patient lies effectively in the middle of the hospital bed, reducing the pressure of confrontation between medical staff and patients. The head pad 6 prevents the head from being knocked when the strap 27 pulls the patient. The electric push rod 92 is contracted to drive the tension roller 95 to descend and press the bed cloth 11 to keep it flat, enabling the patient to lie comfortably on the bed, and at the same time avoiding wrinkles in the bed cloth 11.

[0034] After the CPR examination and nursing, when turning the patient over, for example, turning the patient to the left side, the two electric push rods 92 on the right side are synchronously pushed to raise the Z-shaped arm 94, prompting the tension roller 95 to rise to a certain height. The second motor 82 on this side drives the winding roller 83 to wind up the bed cloth 11, so that the bed cloth 11 re-adheres to the raised tension roller 95 to maintain tension. At this time, the right end of the bed cloth 11 rises and drives the patient's body to turn over. The turned-over patient is buffered and blocked by the baffle 103 on the left side to prevent excessive turning from causing injury to the human body and preventing parts from colliding. While turning over, the right end of the bed cloth 11 continues to be wound up to maintain tension with the tension roller 95.

[0035] After the patient's turning over is completed, the patient's body is located at a position close to the left side of the bed body 1. Through the reset of the electric push rod 92 on the right side, the tension roller 95 presses down the right end of the bed cloth 11 again, prompting the bed cloth 11 to resume horizontal alignment. At this time, continue to wind up the right bed cloth 11, and the movement of the bed cloth 11 can be used to drag the patient's body towards the middle of the bed body 1, so as to achieve the purpose of resetting the patient's lying position, improve the comfort of the patient's rest, avoid excessive extrusion on one side of the bed body 1, and avoid the risk of the patient rolling and falling from one side of the bed body 1. Through the above method of the equipment in this case, the patient can be further turned over, reducing the pressure of confrontation between medical staff and patients with mental illness or obesity, reducing the difficulty of turning over and making it easier to carry out medical work.
