[0002] Hospital-acquired pneumonia and ventilator-associated pneumonia are the most common hospital-acquired infections in my country, with high mortality and heavy medical burden. A survey in my country showed that among 17,358 ICU inpatients in 46 hospitals, the total number of intubation days was 91,448 days, the incidence of VAP was 8.9 / 1,000 mechanical ventilation days, the incidence of VAP in mechanically ventilated patients was 9.7% to 48.4%, and the mortality rate was 21.2% to 43.2%.
[0003] Research results at home and abroad have shown that lower respiratory tract infections, including HAP / VAP, rank first among hospital-acquired infections1. Inadequate airway clearance may further aggravate lung inflammation. Therefore, it is crucial to clear airway mucus in patients with lung infections.
[0004] In order to effectively achieve airway clearance, it is usually necessary to adjust the medical bed so that the patient is in a 15° head-down-feet-high position, for 10 to 15 minutes each time, twice a day. At the same time, medical staff are required to promote the discharge of airway secretions, and an external high-frequency vibration expectoration device is required to oscillate and pat the patient to loosen the secretions and assist the patient in expelling airway secretions.
[0005] Medical beds are relatively common medical equipment and are installed in hospital wards. Medical beds are mainly used for treatment, rescue and transfer of patients in intensive care units and general wards of hospitals. Traditional medical beds have the problem of no oscillation drainage function and low accuracy of position adjustment. Summary of the invention
[0006] In view of the above-mentioned technical deficiencies, the purpose of the present invention is to provide an integrated automatic body position drainage oscillating bed and system, which has the advantages of conveniently adjusting the patient's position and oscillating and patting the patient to help the patient eliminate airway secretions.
[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions: The present invention provides an integrated automatic postural drainage oscillating bed and system, comprising a bed frame, a frame adapted to the bed frame being fixed on the bed frame, a thin mattress being placed on the side of the frame away from the bed frame, a plurality of support plates being evenly fixed on the frame, a plurality of main electric push rods arranged in an array being detachably fixed on each of the support plates, and a beating block that contacts the lower surface of the thin mattress being movably connected to the extended end of each of the main electric push rods.
[0008] By adopting the above technical solution, the bed frame is supported, and the patient lies on a thin mattress. The main electric push rod provides power to drive the flapping block movably connected to its extended end to move in the vertical direction. The main electric push rod can drive the flapping block to move to a suitable height so that the patient can assume the required position and use gravity to assist in the discharge of airway secretions. It can also drive the flapping block to perform high-frequency and low-amplitude movements to oscillate and flap the patient's appropriate position, repeatedly generate shear forces similar to coughing, change the physical and chemical properties of the secretions, loosen the secretions, and promote the secretions of the fine bronchi around the lungs to move to the large airways, further assisting the patient in expelling airway secretions. By setting up multiple main electric push rods, the main electric push rod in a suitable position can be selected according to the patient's body shape to achieve precise position drainage or oscillation operations, assisting medical staff in reducing nursing pressure while effectively improving comfort.
[0009] Preferably, a turning component for driving the patient to turn over so that the patient lies in a prone position is provided on the side of the thin mattress facing away from the frame.
[0010] By adopting the above technical solution, the turning component provides power so that the bedridden patient can be turned over and placed in a prone position, thereby increasing the ventilation volume and promoting the removal of sputum in the lower lung by gravity.
[0011] Preferably, the flipping assembly includes a square frame placed on a thin mattress, a bed cloth for facilitating the patient's lying and supporting the patient being detachably fixedly connected inside the square frame, auxiliary electric push rods are fixed on both sides of the left and right sides of the bed frame, and the extended ends of each auxiliary electric push rod are hingedly connected to the square frame via a support rod, and a binding assembly for fixing the patient is provided on the square frame.
[0012] By adopting the above technical solution, the square frame and the bed sheet support the patient, and the auxiliary electric push rod provides power to drive the square frame and the bed sheet to move in the vertical direction. When the square frame and the bed sheet move to the appropriate position, the bed sheet is manually flipped over to facilitate the patient lying on the bed sheet to turn over to a prone position. The patient who is unable to move can complete the position change with the assistance of a medical staff, saving manpower. By setting a binding component to fix the patient, the possibility of the patient falling off the bed sheet under the action of gravity during the position flipping process is reduced.
[0013] Preferably, the binding assembly includes a head limit block, an upper body limit block, a hip limit block and a leg limit block that contact the patient's head, a T-shaped through hole is penetrated in the middle position of the head limit block for facilitating the patient's breathing and not affecting the patient's vision, the head limit block, the upper body limit block, the hip limit block and the leg limit block are fixed by connecting belts, and the head limit block, the upper body limit block, the hip limit block and the leg limit block are all detachably fixedly connected to the square frame by binding belts.
[0014] By adopting the above technical solution, the patient's head, upper body, hips and legs are respectively fixed by the head limit block, upper body limit block, hip limit block and leg limit block to reduce the possibility of the patient falling during the flipping process and improve the safety of the device.
[0015] Preferably, both the front and rear sides of the frame are provided with guardrail components for protecting the patient.
[0016] By adopting the above technical solution and setting a guardrail assembly, the patient in the device is protected.
[0017] Preferably, the guardrail assembly includes two connecting seats fixed on the outer side wall of the frame, and a protective plate is rotatably connected between the two connecting seats.
[0018] By adopting the above technical solution, the protective plate is supported by the connecting seat, and the protective plate protects the patient, thereby reducing the possibility of the patient falling.
[0019] Preferably, the guardrail assembly includes four axially arranged vertical poles, and the four vertical poles are fixedly connected by a number of evenly arranged cross bars. Each two adjacent vertical poles are integrated with a hollow sleeve at the end away from the frame, and a long shaft rotatably connected to the sleeve passes through the two sleeves. The vertical poles are connected to the frame through a connecting assembly.
[0020] By adopting the above technical solution, the vertical pole, horizontal pole, sleeve and long axis form a guardrail assembly to protect the patient in the device. By setting the connecting assembly, it is convenient to support and flip the vertical pole without affecting the patient's bed movement or flipping.
[0021] Preferably, the connecting assembly includes a mounting seat fixed on the outer wall of the frame, a guide tube with a hollow inner cavity and open ends fixed on the mounting seat, a connecting rod slidingly connected to the guide tube passes through the guide tube, an anti-drop plate located below the guide tube is fixed at one end of the connecting rod, and the other end is hingedly connected to the end of the vertical pole through a connecting block, a top plate is fixed to the circumferential outer wall of the vertical pole, and the diameters of the top plate and the anti-drop plate are both larger than the outer diameter of the guide tube.
[0022] By adopting the above technical solution, when protection is needed, the upright pole is vertical and located above the connecting rod, one end of the upright pole extends into the guide tube, the lower surface of the top plate overlaps the guide tube, the upright pole, the connecting block and the connecting rod are hingedly connected at the inner cavity of the guide tube, and the upright pole is supported by the guide tube. When protection is not needed, the upright pole is manually pushed up, the upright pole, the connecting block and the connecting rod are hingedly connected at the outer position extending out of the guide tube, the upright pole and the connecting block are manually rotated, the connecting block overlaps the top of the guide tube, and the upright pole is flipped so that the long axis is located below the frame, which does not affect the patient's bed movement or flipping.
[0023] Preferably, a winding roller located between two sleeves is fixed on the circumferential outer wall of the long shaft, the winding roller coincides with the center line of the long shaft, a slot is passed through the winding roller, one end of the long shaft passes through the adjacent sleeve, and a crank is coaxially fixed to the end of the long shaft passing through one end of the sleeve.
[0024] By adopting the above technical solution, when an immobile patient needs to turn over or adjust his position, he can insert one end of the quilt into the slot and connect it with the slot by manually rotating the crank to provide power, thereby driving the long axis and the winding roller coaxially fixed with the crank to rotate. The rotation of the winding roller drives the patient's quilt to be rolled up outside the winding roller, thereby reducing the possibility that the accumulated quilt will affect the patient's turning over and position adjustment or cause injury to the patient.
[0025] Preferably, each of the uprights is sleeved with a movable tube that is slidably connected to the uprights, and the four movable tubes are connected into an integrated structure by a middle fixed tube and two side fixed tubes. The movable tube and the sleeve are fixedly connected by a follower spring sleeved outside the uprights, and an arc plate is fixed on the middle fixed tube, and the arc plate is arranged inclined toward one side of the bed frame.
[0026] By adopting the above technical solution, in the initial state, the arc plate is close to the winding roller. During the winding process of the quilt, the quilt passes through the arc plate, and the arc plate plays a limiting role in the winding of the quilt. As the thickness of the quilt wound outside the winding roller increases, the arc plate moves downward, and the follower spring is stretched. The arc plate always presses the quilt wound outside the winding roller, which plays a limiting role on the quilt and reduces the possibility of the quilt slipping off the winding roller or falling to the ground.

The main electric push rod can drive the flapping block to a suitable height so that the patient can assume the required body position and use gravity to assist in the discharge of airway secretions, and can also drive the flapping block to perform high-frequency and low-amplitude movements to oscillate and flap the patient's appropriate position, repeatedly generating shear forces similar to coughing, changing the physical and chemical properties of the secretions, loosening the secretions, and promoting the secretions of the fine bronchi around the lungs to move to the large airways, further assisting the patient in eliminating airway secretions. By setting up multiple main electric push rods, the main electric push rod in a suitable position can be selected according to the patient's body shape to achieve precise position drainage or oscillation operations, assisting medical staff to reduce nursing pressure while effectively improving comfort.
[0028] The integrated automatic postural drainage oscillating bed and system, with a square frame and bed cloth supporting the patient, is powered by a secondary electric push rod to drive the square frame and bed cloth to move in the vertical direction. When the square frame and bed cloth are moved to the appropriate position, the bed cloth is manually flipped over to facilitate the patient lying on the bed cloth to turn over to a prone position. By increasing the ventilation volume and using gravity to promote the removal of sputum from the lower lung, the functionality of the device is increased. Patients with no mobility can complete the position change with the assistance of a medical staff member, saving manpower. By setting up a binding component to fix the patient, the possibility of the patient falling off the bed cloth under the action of gravity during the position flipping process is reduced.
[0029] The integrated automatic postural drainage oscillating bed and system allows immobile patients to insert one end of the quilt into the slot and connect it to the slot by clamping it. The crank is manually rotated to provide power, which drives the long shaft and the winding roller coaxially fixed with the crank to rotate. The rotation of the winding roller drives the patient's quilt to be rolled around the outside of the winding roller, reducing the possibility of accumulated quilts affecting the patient's turning over and postural adjustment or causing injury to the patient.

An arc plate 17 that compresses the quilt wound around the winding roller 10 is fixed on the intermediate fixed tube 14, and the arc plate 17 is arranged tilted toward one side of the bed frame 1.
[0052] like Fig. 9 and Fig.10 and Fig.11 In the initial state, the arc plate 17 is close to the winding roller 10. During the winding process of the quilt, the quilt passes through the arc plate 17, and the arc plate 17 limits the winding of the quilt. As the thickness of the quilt wound outside the winding roller 10 increases, the arc plate 17 moves downward, and the follower spring 16 is stretched. The arc plate 17 always presses the quilt wound outside the winding roller 10, limits the quilt, and reduces the possibility of the quilt slipping off the winding roller 10 or falling to the ground.
[0053] like Fig. 9 and Fig.10 When the quilt is wound around the reel 10, in order to reduce the possibility of the quilt rotating due to the shaking of the crank 12, a limiting component 1 is provided outside the long axis 06 to limit the rotation of the long axis 06.
[0054] like Fig.12 and Fig.13 The limiting assembly 1 includes an outer supporting seat 101 and an inner supporting seat 102 which are sleeved outside the long axis 06 and fixed to the sleeve 05, the inner supporting seat 102 is located inside the outer supporting seat 101, the long axis 06 passes through the outer supporting seat 101 and the inner supporting seat 102 and is rotatably connected with the outer supporting seat 101 and the inner supporting seat 102, a ratchet 103 is arranged between the outer supporting seat 101 and the inner supporting seat 102, the ratchet 103 is nested outside the long axis 06 and coaxially fixed with the long axis 06, two relatively arranged sliding grooves 104 are provided on the outer supporting seat 101, and a slide plate 105 is slidably connected in the two sliding grooves 104, the slide plate 105 is connected to the outer supporting seat 101 through a torsion spring, and one end of the slide plate 105 is inserted into the ratchet 103 and is clamped and connected with the ratchet 103.
[0055] like Fig.12 and Fig.13 Before rotating the crank 12, grab the slide plate 105 and push it manually. The slide plate 105 moves until it is no longer in contact with the ratchet 103, and the torsion spring is compressed. At this time, the slide plate 105 does not affect the rotation of the crank 12. After the quilt is rolled up outside the winding roller 10, release the slide plate 105. The torsion spring provides elastic potential energy, and the slide plate 105 moves into the ratchet 103 and is connected to the ratchet 103. The slide groove 104 guides the movement of the slide plate 105.
[0056] When in use, the power is turned on, the switch is turned on, the patient lies on the bed sheet 602, and the patient's quilt is fixed to the winding roller 10 by the installation belt to reduce the possibility of the quilt falling off. When the patient needs to adjust the body position or turn over, the medical staff grasps the slide plate 105 with one hand and manually pushes the slide plate 105, the slide plate 105 slides in the slide groove 104, the torsion spring is compressed, and the slide plate 105 moves to not contact the ratchet 103. The other hand grasps the crank 12 and manually rotates the crank 12 to provide power. The rotation of the crank 12 drives the long shaft 06 and the winding roller 10 of the integrated structure with the crank 12 to rotate, and the rotation of the winding roller 10 drives the quilt to be wound around the winding roller 10; When the quilt is wound outside the winding roller 10, the quilt passes through the arc plate 17. The arc plate 17 is arranged obliquely so as not to jam the quilt. As the thickness of the quilt wound outside the winding roller 10 increases, the arc plate 17 moves downward, and the follower spring 16 is stretched. The arc plate 17 always presses the quilt wound outside the winding roller 10, thereby limiting the quilt. When the quilt is completely wound outside the winding roller 10 and does not affect the patient, the medical staff first loosens the slide plate 105, the torsion spring rebounds, pushes the slide plate 105 back to the initial position and snaps into the ratchet 103, and then loosens the crank 12. At this time, the crank 12 will not shake and affect the winding roller 10 and the quilt, and the quilt will not affect the patient. When the patient needs to adjust the body position, according to the patient's position and body shape, the main electric push rod 4 is opened at a suitable position, and the main electric push rod 4 provides power to drive the slapping block 5 movably connected to its extended end to move in the vertical direction. The slapping block 5 moves and pushes the thin mattress 3 and the bed cloth 602 to move, so that the bedridden patient is in the required body position, and gravity is used to assist the discharge of airway secretions, which is convenient for drainage; When the patient needs to be tapped, the main electric push rod 4 at several appropriate positions is controlled to drive the tapping block 5 to perform high-frequency and low-amplitude movements, and oscillate and tap the appropriate positions of the patient, repeatedly generating a shear force similar to coughing, changing the physical and chemical properties of the secretions, loosening the secretions, and promoting the secretions of the fine bronchi around the lungs to move to the large airways, thereby helping the patient to expel airway secretions; When the patient with limited mobility gradually gets better, he needs to assist in prone expectoration. The staff first grabs the vertical pole 03 and manually pushes the vertical pole 03 upward. After the vertical pole 03, the connecting block 905 and the connecting rod 903 are hingedly connected to extend the guide tube 902, the vertical pole 03 and the connecting block 905 are manually rotated. The connecting block 905 is overlapped on the top of the guide tube 902, and the vertical pole 03 is turned over so that the long axis 06, the winding roller 10 and the quilt wound outside the winding roller 10 are turned over to the bottom of the frame 2; Then place the head positioning block 707 on the left and right sides of the patient's head, the head limiting block 701 is placed above the patient's head, the head limiting block 701 is fixed to the square frame 601 by the binding belt 706, the head limiting block 701, the bed sheet 602 and the two head positioning blocks 707 cooperate to clamp the patient's head, the upper body limiting block 702 is placed above the patient's upper body, the arm positioning block 70 is placed beside the patient's arm, the upper body limiting block 702 is fixed to the square frame 601 by the binding belt 706, the bed sheet 602, the arm positioning block 70 and the upper body positioning block cooperate to clamp the patient's arm and For the upper body, the crotch limit block 703 is placed above the patient's crotch, the hand positioning block 709 is on both sides of the patient's hand and in contact with the patient's hand, the crotch limit block 703 is fixed to the square frame 601 through the binding belt 706, the bed sheet 602, the crotch limit block 703 and the hand positioning block 709 fix the patient's crotch and hands, the leg limit block 704 is fixed to the square frame 601 through the binding belt 706, and the leg limit block 704 and the bed sheet 602 cooperate to fix the patient's legs, so that the patient is stably connected to the bed sheet 602, reducing the possibility of the patient falling during the turning process, and improving the safety of the device; Then, the auxiliary electric push rod 603 is turned on, and the auxiliary electric push rod 603 provides power to drive the support rod 604 hingedly connected to the extended end of the auxiliary electric push rod 603 and the square frame 601 rotatably connected to the support rod 604 to move in the vertical direction. After the square frame 601 moves to a suitable position, the medical staff pushes the square frame 601 to rotate. After the square frame 601 rotates to a suitable position, the auxiliary electric push rod 603 drives the square frame 601 and the patient on the square frame 601 to move downward and fall steadily onto the thin mattress 3, so that the patient with limited mobility can lie prone and increase the ventilation volume with the help of gravity to promote the removal of sputum in the lower lung; Remove the head limit block 701, the head positioning block 707, the upper body limit block 702, the arm positioning block 70, the hip limit block 703, the hand positioning block 709 and the leg limit block 704, and the auxiliary electric push rod 603 drives the square frame 601 to move upward until the square frame 601 and the bed cloth 602 do not affect the patient. At this time, nursing work such as back rubbing can also be performed on the prone patient. Patients with no mobility can complete the position change with the assistance of a medical staff, saving manpower.
[0057] When the patient does not need to lie prone, the staff fixes the head limit block 701, the head positioning block 707, the upper body limit block 702, the arm positioning block 70, the hip limit block 703, the hand positioning block 709 and the leg limit block 704 to the patient and the square frame 601, and then drives the square frame 601 to move up through the auxiliary electric push rod 603. After the square frame 601 moves up to a suitable position, the square frame 601 is flipped over again, and the auxiliary electric push rod 603 drives the square frame 601 to move down until the bed cloth 602 and the square frame 601 are in contact with the thin mattress 3. At this time, the patient is in a lying position, and the head limit block 701, the head positioning block 707, the upper body limit block 702, the arm positioning block 70, the hip limit block 703, the hand positioning block 709 and the leg limit block 704 are removed; When the bed is not being turned over or moved, the staff member grabs the upright pole 03 and turns the upright pole 03 in the opposite direction until the upright pole 03 is located above the connecting rod 903 and is in a vertical state, and then releases the upright pole 03. The upright pole 03 moves downward under the action of gravity, and one end of the upright pole 03 extends into the guide tube 902. The lower surface of the top plate 906 overlaps the guide tube 902. The guide tube 902 supports the top plate 906. The hinged connection position of the upright pole 03, the connecting block 905 and the connecting rod 903 extends. It extends to the inner cavity of the guide tube 902 and supports the vertical rod 03 through the guide tube 902. At this time, the vertical rod 03 is in a vertical state, and the quilt wound outside the winding roller 10 is located above the bed cloth 602. At this time, the slide plate 105 is grasped and manually pushed. The slide plate 105 moves until it is not in contact with the ratchet 103, and then the crank 12 is rotated. The crank 12 drives the long shaft 06 and the winding roller 10 to rotate in the opposite direction, and the quilt is detached from the winding roller 10, which does not affect the normal use of the quilt.
