Description

Technical Field

[0001] This invention relates to the field of critical care nursing bed-raising assistance technology, specifically a critical care nursing bed-raising assistance device. Background Technology

[0002] When caring for critically ill patients, it is best to turn them over every 2 hours to avoid local pressure on their bodies. At the same time, appropriate massage is also needed to promote blood circulation. In addition, when caring for critically ill patients, staff need to help them get out of bed to receive treatment. Currently, there are bed-raising assistive devices on the market that can replace manual labor to help critically ill patients get out of bed, reducing the workload of staff.

[0003] The prior art, patent number CN114601656A, entitled "A Critical Care Nursing Bed-Awake Assistance Device," discloses that after a rotating plate supports the patient's upper body, the patient can forcefully rotate the movable plate downwards. The patient's lower legs move with the movable plate, causing the patient's knees to bend, thus putting the patient in a sitting position. Medical staff can then assist the patient into a wheelchair, allowing them to be pushed for physical examinations or to have wounds checked. This mechanism eliminates the need for the patient to exert force to bend their body, avoiding excessive force that could cause secondary damage to the wound, making it safer and preventing injury from manual assistance. When the patient needs to lie down again, the patient's back is placed against the rotating plate. Once the patient is ready, the rotating plate can be rotated in the opposite direction, causing the movable plate to support the patient's lower legs and gradually straighten. After the rotating plate has rotated in the opposite direction, the device returns to its initial state, allowing the patient to lie on the device for treatment and recuperation.

[0004] The aforementioned rotating plate has a simple rectangular plate structure. When a patient lies on the rotating plate, the plate rotates to support the patient's upper body. However, if staff do not support the patient's upper body, the upper body may tilt, making it difficult for the rotating plate to stably support the patient's upper body. Summary of the Invention

[0005] The purpose of this invention is to provide a bed-raising assistive device for critical care nursing, in order to solve the problem mentioned in the background art that the structure of the rotating plate on the market is a rectangular plate structure, which is relatively simple. When the patient lies on the rotating plate, the rotating plate supports the patient's upper body. However, if the staff does not hold the patient's upper body, the upper body may tilt, thus making it impossible for the rotating plate to stably support the patient's upper body.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a critical care nursing bed-raising assistance device, including a main board, wherein a first assist plate for lowering the legs is rotatably connected to the left side of the main board;

[0007] The right side of the motherboard is rotatably connected to a second support plate that can support the upper body;

[0008] Two limiting anti-tipping components are symmetrically installed on the upper surface of the second assist plate.

[0009] The upper surface of the first assist plate is slidably connected to a patting component, which drives the patting block to pat the back of the human body through a reciprocating lifting structure, thereby replacing manual labor and reducing workload.

[0010] The upper surface of the main board is symmetrically equipped with a turning component, which turns and fixes the human body by moving the turning auxiliary plate with an arc-shaped structure on one side;

[0012] Preferably, the limiting anti-tipping component includes a protective airbag embedded in the upper surface of the second assist plate through a slot, and the two protective airbags are symmetrically arranged about the transverse center line of the second assist plate. Furthermore, an air-storing airbag is installed in the slot inside the right side of the second assist plate, and the upper part of the air-storing airbag is connected to the interior of the protective airbag through a connecting pipe.

[0013] The above structure allows the gas inside the storage airbag to enter the protective airbag effectively.

[0014] Preferably, the bottom surface of the second assist plate has a slotted bearing connected to a crossbar, and the right end of the crossbar is fixed with a second threaded rod. The right end of the second threaded rod is threadedly connected to a compression plate. An air storage bladder is provided on the left side of the compression plate. The gas in the air storage bladder enters the protective bladder through the compression of the compression plate. The number of protective bladders is set in a 2:1 ratio with the number of air storage bladders.

[0015] Preferably, the striking assembly is provided with protective airbags on both the front and rear sides, and the striking assembly includes striking blocks that are slidably disposed in the second assist plate. There are four sets of cylindrical striking blocks, and a lifting rod is fixed to the bottom of the striking block. A mounting plate is installed below the lifting rod, and a return spring is nested and connected to the upper outer side of the lifting rod. The left side of the mounting plate is higher than the right side, and the bottom left side of the mounting plate is inclined.

[0016] With the above-mentioned structure, the protective airbag can effectively perform protective operations.

[0017] Preferably, a single-turn reciprocating screw is fixed to the left end of the crossbar, and a push plate is threaded to the outer side of the left end of the single-turn reciprocating screw. A mounting plate is provided above the push plate, and the mounting plate reciprocates and rises and falls by moving the push plate left and right. At the same time, a third torsion spring is nested to the left end of the single-turn reciprocating screw, and both the single-turn reciprocating screw and the second threaded rod are connected to the internal bearing of the second assist plate.

[0018] With the above structure, the single-rotor reciprocating screw rotates, driving the push plate to move back and forth.

[0019] Preferably, the bottom of the main board is fixed with a support plate in an "L" shape, a connecting rope is wound around the outer side of the right end of the crossbar, and the lower end of the connecting rope passes through the lower surface of the second assist plate and is connected to the support plate. At the same time, a guide wheel for guiding the connecting rope is installed on the support plate.

[0020] With the above-described structure, the guide wheel can guide the direction of the connecting rope.

[0021] Preferably, the upper surface of the motherboard is symmetrically slotted and connected to a first threaded rod, and the outer end of the first threaded rod penetrates the outer side of the motherboard. The outer side of the first threaded rod is threadedly connected to a turning auxiliary plate. The turning assembly includes the turning auxiliary plate, and one side of the turning auxiliary plate is arranged in an arc shape.

[0022] With the above-mentioned structure, the turning auxiliary plate with an arc-shaped structure on one side can perform the turning operation very well.

[0023] Preferably, the upper surfaces of the motherboard, the first auxiliary plate, and the second auxiliary plate are bonded to the protective pad via the first Velcro assembly, and the front and rear sides of the protective pad are symmetrically sewn with connecting straps, and four connecting straps are provided. At the same time, the outer ends of the connecting straps are sewn with collars, and one side of the connecting strap is bonded to the first auxiliary plate and the second auxiliary plate via the second Velcro assembly.

[0024] Both the first and second hook and loop fastener assemblies consist of sub-hooks and female hook and loop fasteners. The sub-hooks from the first hook and loop fastener assembly are installed on the upper surfaces of the main board, the first auxiliary plate, and the second auxiliary plate, and the female hook and loop fastener from the first hook and loop fastener assembly is installed on the lower surface of the protective pad. The sub-hooks from the second hook and loop fastener assembly are fixed to the outer sides of the first and second auxiliary plates, and the female hook and loop fastener from the second hook and loop fastener assembly is installed on one side of the connecting strap.

[0025] With the above-described structure, the first Velcro assembly can detach the protective pad from the motherboard.

[0026] Preferably, the left and right sides of the turning auxiliary plate are slotted and slidably connected with lifting rods, and the two lifting rods are staggered and inserted into the collar.

[0027] With the above structure, the lifting rod can move along with the collar when it moves.

[0028] Preferably, an assist rod is connected to the middle of the rear side of the motherboard through a bearing, a first rotating rod is connected to the left side of the motherboard through a slotted bearing, a first assist plate is fixed to the outer side of the first rotating rod, a first torsion spring is nested at the front end of the first rotating rod, and a first adjustment rope is wound around the rear end of the first rotating rod.

[0029] With the above structure, the stored force of the first torsion spring can automatically drive the first rotating rod to rotate in the opposite direction.

[0030] The motherboard has a slotted bearing on the right side connected to a second rotating rod, and a second assist plate is fixed through the outer side of the second rotating rod. The front end of the second rotating rod is wound with a second adjusting rope, and the rear end of the second rotating rod is nested with a second torsion spring.

[0031] The rear end of the assist rod is wound with a first control rope, and the front end of the assist rod is wound with a second control rope. When the assist rod rotates counterclockwise, it simultaneously winds and coils the second control rope and the first control rope.

[0032] With the above-mentioned structure, the rotating lever can simultaneously drive the second and first control ropes to wind up, reducing the use of a power source.

[0033] Compared with the prior art, the beneficial effects of the present invention are as follows: In this critical care nursing bed-raising assistive device, the moving compression plate compresses the air storage bladder, causing the gas inside the air storage bladder to enter the protective bladder in the limiting and anti-tipping component through the connecting pipe. This causes the two protective bladders to expand, thereby pushing the corresponding protective pads upward. The pushed-up protective pads then limit and protect the sides of the upper body, preventing tilting when the second assistive plate rotates upward and pushes the upper body upward. This allows the second assistive plate to smoothly assist in pushing the upper body upward. The specific details are as follows:

[0034] (1) When the second assist plate rotates upward, it automatically pulls the connecting rope, which in turn causes the connecting rope to rotate the crossbar and the second threaded rod. Then, the second threaded rod causes the extrusion plate to move and extrude the air storage bag. This causes the gas in the air storage bag to enter the protective air bag in the limit anti-tipping component through the connecting pipe, causing the volume of the two protective air bags to expand. This causes the expanded two protective air bags to push the protective pads at the corresponding positions upward, which then allows the pushed-up protective pads to limit and protect the upper body of the human body on both sides, preventing the upper body of the human body from tilting when the second assist plate rotates upward and causes the upper body of the human body to stand up. This allows the second assist plate to smoothly push the upper body of the human body upward.

[0035] Furthermore, when the second assist plate rotates upward, it can automatically pull the connecting rope without the need for external force to drive the crossbar to rotate, thereby saving energy and reducing the use of power sources;

[0036] (2) When the crossbar rotates, it can drive the single-turn reciprocating screw to rotate together, which in turn drives the push plate to move back and forth. This push plate pushes the mounting plate upwards in a reciprocating manner. Therefore, with the storage of the reset spring, the patting block can move up and down in a reciprocating manner, which allows the patting block to pat the back of the upper body of the human body in a reciprocating manner. This increases the functionality of the bed-raising assistance device and can meet different usage needs. By patting the back, it can promote the timely discharge of sputum in critically ill patients.

[0037] Furthermore, the rotation of the crossbar can drive the single-turn reciprocating screw to rotate, thereby causing the push plate to move back and forth without the need for an external power source.

[0038] By manually rotating the first threaded rod, the first threaded rod can drive the turning auxiliary plate inside the turning assembly to move, so that the turning auxiliary plate with an arc-shaped structure on one side can push one side of the human body to turn over. At the same time, the turning auxiliary plate can automatically fix itself after moving to a certain position, so as to fix the human body after turning over, making it convenient to massage and wipe the human body after turning over.

[0039] At the same time, the lifting rod is taken out from the turning auxiliary plate and inserted into the collar. Then, when the turning auxiliary plate moves, it will drive the lifting rod and the connecting belt to move together. The connecting belt will drive the protective pad to move, and then the protective pad will move to assist the upper and lower body in turning over. Therefore, the turning auxiliary plate can turn over more effectively. Attached Figure Description

[0052] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0053] Example 1: In this implementation, when assisting critically ill patients to get out of bed, the upper body can be restricted to prevent tilting during the process. See attached document for details. Figures 1-4 As shown, the system includes a main board 1. A first assist plate 2, which allows the legs to be lowered, is rotatably connected to the left side of the main board 1. A second assist plate 3, which supports the upper body, is rotatably connected to the right side of the main board 1. Two limiting anti-tipping components are symmetrically installed on the upper surface of the second assist plate 3. By expanding the volume of the two protective airbags 11 upwards, the two protective airbags 11 push up the protective pads 4 at the corresponding positions above to limit the sides of the human body's arms and prevent the human body from tipping over. A support vertical rod 18 is fixed at the bottom of the main board 1, and a bed board body 6 is rotatably connected to the bottom of the support vertical rod 18. The limiting anti-tipping components include protective airbags 11 that are grooved and embedded in the upper surface of the second assist plate 3. The two protective airbags 11 are symmetrically arranged about the horizontal center line of the second assist plate 3. An air storage airbag 17 is installed in the groove inside the right side of the second assist plate 3, and the upper part of the air storage airbag 17 is connected to the inside of the protective airbag 11 through a connecting pipe 111. The right side of the main board 1 is connected to a slotted bearing with a second rotating rod 301. A second assist plate 3 is fixed through the outer side of the second rotating rod 301. A second control rope 302 is wound around the front end of the second rotating rod 301. A second torsion spring 303 is nested around the rear end of the second rotating rod 301. A first control rope 202 is wound around the rear end of the assist rod 9. A second control rope 302 is wound around the front end of the assist rod 9. When the assist rod 9 rotates counterclockwise, it simultaneously winds and coils the second control rope 302 and the first control rope 202.

[0054] The bottom surface of the second assist plate 3 has a slotted bearing connected to a crossbar 15, and the right end of the crossbar 15 is fixed with a second threaded rod 152. The outer right end of the second threaded rod 152 is threadedly connected to a compression plate 16. An air-storage bladder 17 is located on the left side of the compression plate 16. Gas in the air-storage bladder 17 is compressed by the compression plate 16 and enters the protective airbag 11. The number of protective airbags 11 is set in a 2:1 ratio with the number of air-storage bladders 17. The crossbar 1... A single-turn reciprocating screw 151 is fixed to the left end of 5, and a push plate 19 is threadedly connected to the outer side of the left end of the single-turn reciprocating screw 151. A mounting plate 123 is provided above the push plate 19, and the mounting plate 123 reciprocates and rises and falls by moving the push plate 19 left and right. At the same time, a third torsion spring 153 is nested and connected to the left end of the single-turn reciprocating screw 151, and both the single-turn reciprocating screw 151 and the second threaded rod 152 are connected to the internal bearing of the second assist plate 3.

[0055] The bottom of the main board 1 is fixed with a support plate 13 in an "L" shape. A connecting rope 14 is wrapped around the outer side of the right end of the crossbar 15, and the lower end of the connecting rope 14 passes through the lower surface of the second assist plate 3 and is connected to the support plate 13. At the same time, a guide wheel for guiding the connecting rope 14 is installed on the support plate 13.

[0056] The supporting vertical rod 18 at the bottom of the entire bed-raising assist device is rotatably mounted on the external bed board body 6. Then, the critically ill patient lies on the protective mat 4. When it is necessary to assist the critically ill patient in getting up, the supporting vertical rod 18 is rotated by the external motor. At this time, the supporting vertical rod 18 drives the main board 1 to rotate.

[0057] See attached document Figures 5-8 As shown, the rear end of the assist rod 9 is then connected to an external motor, causing the external motor to drive the assist rod 9 to rotate. When the assist rod 9 rotates counterclockwise, it simultaneously winds up the first control rope 202 and the second control rope 302, which in turn causes the first control rope 202 to drive the first rotating rod 201 to rotate, causing the first rotating rod 201 to drive the first assist plate 2 to rotate downward. At this time, the first assist plate 2 causes the lower limbs to rotate and bend downward. At this time, the second torsion spring 303 begins to store force, which is convenient for automatically driving the first rotating rod 201 to rotate in the opposite direction later through the stored force of the second torsion spring 303. Similarly, the second control rope 302 drives the second rotating rod 301 to rotate. At this time, the second rotating rod 301 drives the second assist plate 3 to rotate upward. At this time, the second assist plate 3 causes the upper body to flip upward and stand up. At this time, the second torsion spring 303 begins to store force.

[0058] During the upward flipping process of the second assist plate 3, it will automatically pull the connecting rope 14. At this time, one end of the connecting rope 14 drives the crossbar 15 to rotate automatically. When the crossbar 15 rotates, it drives the single-turn reciprocating screw 151 and the second threaded rod 152 to rotate together. When the second threaded rod 152 rotates, it drives the outer threaded extrusion plate 16 to move to the left, so that the extrusion plate 16 extrudes the air storage bag 17, so that the gas in the air storage bag 17 enters the protective bag 11 through the connecting pipe 111. At this time, the volume of the protective bag 11 begins to expand, pushing up the protective pad 4 at the corresponding position, so that the protective pad 4 at the corresponding position protrudes to limit the protection on both sides of the upper body of the human body, preventing the upper body of the human body from tilting and falling when getting up, thus making the second assist plate 3 have high stability when getting up.

[0059] Example 2: In this example, while assisting the upper body in getting out of bed, the back can be patted repeatedly to promote the timely expulsion of sputum in critically ill patients. See the attached document for details. Figure 3 and attached Figure 7-Figure 8 As shown, a patting component is slidably connected to the upper surface of the first assist plate 2. The patting block 12 is driven to pat the back of the human body through a reciprocating lifting structure, which replaces manual labor and reduces workload. Protective airbags 11 are provided on both the front and rear sides of the patting component. The patting component includes a patting block 12 slidably disposed in the second assist plate 3. There are four sets of cylindrical patting blocks 12. A lifting rod 122 is fixed to the bottom of the patting block 12. A mounting plate 123 is installed below the lifting rod 122. A return spring 121 is nested on the upper outer side of the lifting rod 122. The left side of the mounting plate 123 is higher than the right side of the mounting plate 123. The bottom left side of the mounting plate 123 is inclined.

[0060] As the second assist plate 3 rotates, as described above, the crossbar 15 automatically drives the single-rotor reciprocating screw 151 to rotate. When the single-rotor reciprocating screw 151 rotates, it drives the push plate 19 to move back and forth. When the push plate 19 moves to the right, it pushes the mounting plate 123 upward. At this time, the mounting plate 123 drives the four lifting rods 122 and the patting block 12 to move upward, so that the patting block 12 pats the back of the human body once. At this time, the return spring 121 stores force. When the push plate 19 moves to the left, the stored force of the return spring 121 automatically drives the patting block 12 to move downward. This process repeats, so that the patting block 12 pats the back of the human body in a reciprocating manner, which can promote the timely discharge of sputum in critically ill patients.

[0061] Example 3: In this example, the human body can be turned over to meet different usage needs. Please refer to the appendix for details. Figure 3 and attached Figures 9-11As shown, when a critically ill patient needs to be turned over, a turning assembly is symmetrically installed on the upper surface of the main board 1. The turning and fixing of the human body is achieved by moving the turning auxiliary plate 7 with an arc-shaped structure on one side. The upper surface of the main board 1 is symmetrically slotted and connected to a first threaded rod 10, and the outer end of the first threaded rod 10 penetrates the outer side of the main board 1. The turning auxiliary plate 7 is threadedly connected to the outer side of the first threaded rod 10. The turning assembly includes the turning auxiliary plate 7, and one side of the turning auxiliary plate 7 is set with an arc-shaped structure. The upper surfaces of the main board 1, the first assist plate 2 and the second assist plate 3 are bonded to the protective pad 4 through the first Velcro assembly 5. The front and rear sides of the protective pad 4 are symmetrically sewn with connecting straps 8, and four connecting straps 8 are provided. The outer ends of the connecting straps 8 are sewn with collars 81, and one side of the connecting straps 8 is bonded to the first assist plate 2 and the second assist plate 3 through the second Velcro assembly 82.

[0062] Both the first hook and loop fastener assembly 5 and the second hook and loop fastener assembly 82 are composed of sub-hook and hook and loop fasteners and a female hook and loop fastener. The sub-hook and hook and loop fasteners in the first hook and loop fastener assembly 5 are installed on the upper surface of the main board 1, the first assist plate 2, and the second assist plate 3, and the female hook and loop fasteners in the first hook and loop fastener assembly 5 are installed on the lower surface of the protective pad 4. The sub-hook and hook and loop fasteners in the second hook and loop fastener assembly 82 are fixed to the outer side of the first assist plate 2 and the second assist plate 3, and the female hook and loop fasteners in the second hook and loop fastener assembly 82 are installed on one side of the connecting strap 8. The left and right sides of the turning auxiliary plate 7 are slotted and slidably connected with lifting rods 71, and the two lifting rods 71 ​​are staggered and inserted into the collar 81. A booster rod 9 is connected to the inner bearing through the middle of the rear side of the main board 1. A first rotating rod 201 is connected to the slotted bearing on the left side of the main board 1. A first booster plate 2 is fixed through the outer side of the first rotating rod 201. A first torsion spring 203 is nested at the front end of the first rotating rod 201. A first control rope 202 is wound around the rear end of the first rotating rod 201.

[0063] At this point, pull out the lifting rod 71 inside one of the turning auxiliary plates 7, and then pull out the corresponding connecting strap 8, so that the connecting strap 8 separates from the corresponding first assist plate 2 and second assist plate 3 through the second Velcro assembly 82. Then, put the outer collar 81 of the connecting strap 8 on the outer side of the lifting rod 71. At this time, manually rotate the first threaded rod 10, and the first threaded rod 10 drives the corresponding turning auxiliary plate 7 to move. When the turning auxiliary plate 7 moves, it pushes one side of the human body to turn over by forming an arc shape on one side. At the same time, the turning auxiliary plate 7 drives the connecting strap 8 and the protective pad 4 to move through the lifting rod 71, so that one side of the protective pad 4 also turns over. Then, the protective pad 4 and the turning auxiliary plate 7 work together to turn the human body over. At this time, the human body can be massaged and wiped after turning over, thus completing a series of tasks.

[0064] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
