Description

Technical Field

[0001] The invention relates to the technical field of nursing beds, in particular to an anti-fall medical nursing bed. Background Art

[0002] Medical care beds play a vital role in medical scenarios. They have a series of basic functions to meet different needs. They can flexibly adjust the height of the bed, which is convenient for medical staff to be at a suitable working height when performing various examinations, treatments and nursing operations, reducing the workload. At the same time, the angle of the bed can be adjusted to help the patient's recovery process. In the field of pediatrics, nursing beds are specially designed according to the physiological characteristics of children, providing sick children with a relatively safe and comfortable rest and care environment, which has a positive significance for children's physical recovery.

[0003] Existing child care beds are usually equipped with side fences at the side of the bed as the main means to prevent children from falling out of bed. However, for those children who have gradually acquired a certain degree of mobility, this traditional side fence method cannot completely and effectively prevent their climbing behavior. Young children are prone to climbing over the fence due to curiosity and anxiety caused by the absence of their parents. Although it is theoretically possible to consider continuously increasing the height of the guardrail to prevent young children from climbing over, this approach brings many negative problems. First, a higher guardrail will significantly change the distribution of the center of gravity of the bed, making the center of gravity of the bed higher, thereby seriously reducing the stability of the bed, making the bed more likely to tip over, which will not only cause direct harm to children, but may also endanger the safety of people around them. More importantly, in reality, young children have a strong curiosity and lively nature, and they often find it difficult to realize the dangers that may be caused by climbing over the guardrail. The higher the guardrail design, the greater the harm caused by climbing over.

[0004] Based on the above viewpoints, a person skilled in the art provides a fall-preventing medical care bed. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a fall-proof medical nursing bed, which solves the problem of safety accidents caused by young children climbing over the fence. By means of two figure-eight anti-fall guard plates, it is ensured that young children cannot climb over by stepping on the side walls of the anti-fall guard plates, thereby comprehensively improving the safety of the nursing bed when in use. At the same time, when a young child touches a top support on one side and presses the top support hard in an attempt to climb over the top support, the lever frame will rotate downward, thereby driving the rotating support plate to tilt downward, so that the child's hands grasping the rotating support plate are loosened, thereby preventing the child from continuing to climb the guardrail.

[0017] When a child touches the top support on one side and presses it hard in an attempt to climb over the top support, the lever frame will rotate downward, thereby driving the rotating support plate to tilt downward, causing the child's hand grasping the rotating support plate to loosen, thereby preventing the child from continuing to climb the guardrail.

[0018] While the rotating support plate is tilted and rotated downward, the top of the anti-fall guard plate on the other side rotates outward, and the cover sheet is pulled by the anti-fall guard plate, and the side where the child is standing will be lifted upward, thereby catching the child who slips off the rotating support plate, thereby avoiding safety accidents caused by the child falling due to the rotation of the rotating support plate.

[0019] When the child needs care, the movable ends of the two angle-driven electric cylinders will retract together, thereby driving the tops of the two anti-fall guard plates to rotate outward together, thereby pulling the cover sheet to fully unfold, and then lifting the child, making it easier to carry out child care work.

[0020] When it is necessary to transport a young child, the medical staff must first pull the front and rear sides of the cover sheet to the middle position to ensure that the cover sheet is clamped around the child's waist after being retracted. Then the movable ends of the two angle-driven electric cylinders are extended together to push the anti-fall guard plates on both sides to rotate inward, thereby protecting the young child between them and preventing the young child from being accidentally injured during transportation. When the anti-fall guard plate is at the top position and is under pressure, the anti-fall electric cylinder will still extend. At this time, the spring rod in the tube will push the spring push rod to move inward, and then use the elastic element on the clamping plate to squeeze the rotating shaft part of the drive rod, so that the drive rod is locked with the hinge seat. At this time, the two anti-fall guard plates and the bed body form a triangle shape, which will greatly improve the firmness of the entire medical care bed and fully protect the young child inside from injury.

[0026] Embodiment 2: Figure 5 , Figure 6 As shown, this embodiment provides another technical solution based on the first embodiment. Fixed handles 36 for fixing the sliding tube 331 are installed in the middle and both sides of the bottom of the anti-fall guard plate 31. The fixed handles 36 include a fixed shaft 361 fixed on the anti-fall guard plate 31. The outer end pin of the fixed shaft 361 is connected to a driving handle 362. The outer side wall of the fixed shaft 361 is connected to an extrusion frame 363 through a spring. The driving handle 362 drives the extrusion frame 363 to extend and retract forward and backward by rotating. A fixed head 364 is fixedly connected to the middle position of the extrusion frame 363.

[0027] like Fig. 9 , Fig.10 and Fig.11 As shown, the interior of the sliding tube 331 is connected to a spring rod 332 inside the tube through a spring, and both sides of the interior of the anti-falling guard plate 31 are provided with follower parts 37 used in conjunction with the spring rod 332 inside the tube, and the follower parts 37 include a spring top plate 371, and one end of the spring top plate 371 is fixedly connected to a wedge block 372. The interior of the anti-falling guard plate 31 is also provided with a lifting component 34, and the lifting component 34 includes a bottom rod 341, and the top of the bottom rod 341 is fixedly connected to a top rod 342, and the top pin of the top rod 342 is connected to the top support 32.

[0028] like Fig. 9As shown, the top support 32 includes a supporting rod 322 installed on the top of the anti-falling guard plate 31, and a lever frame 323 is rotatably connected to the outer wall of the supporting rod 322. One end of the lever frame 323 is pin-connected to the top rod 342, and the other end of the lever frame 323 is fixedly connected to the rotating supporting plate 321. The two ends of the cover sheet 14 are detachably connected to the outer walls of the two anti-falling guard plates 31.

[0029] Embodiment 3: Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, this embodiment provides another technical solution based on the first and second embodiments. Electric cylinder mounting frames 8 are installed on both sides of the bottom of the adjustable bed 1. Angle-driven electric cylinders 9 electrically connected to the controller 4 are installed on the two electric cylinder mounting frames 8. A water storage pipe 10 is connected to the movable end of the angle-driven electric cylinder 9. An electric valve 12 is installed on the top of the water storage pipe 10 and at one end close to the angle-driven electric cylinder 9. A water storage tank 13 is connected to the top port of the electric valve 12. A rail push rod 11 is limitedly slidably connected to the other end of the water storage pipe 10. The rail push rod 11 The other end is fixedly connected to a guide rail 5, and the bottom of the guide rail 5 is slidingly connected to a driving rod 6. The bottom of the anti-falling guard plate 31 is fixedly connected to a hinge seat 7, and the other end of the driving rod 6 is pin-connected to the hinge seat 7. Clamping parts 35 are provided on both sides of the interior of the anti-falling guard plate 31 and at the same horizontal height of the two fixed handles 36 below. The clamping parts 35 include a spring-loaded push rod 351, and a clamping plate 352 is fixedly connected to the center of the inner wall of the spring-loaded push rod 351. An elastic component for limiting the rotation of the driving rod 6 is provided on one side wall of the clamping plate 352 close to the hinge seat 7.

[0030] Working principle: When the anti-fall component 3 is needed, the medical staff can step on the foot pedal at the bottom to make the driving frame 22 descend. When the driving frame 22 descends, the driving gear plate 221 will drive the driving gear 234 to rotate, and then drive the connecting tube 231 to rotate together, so that the spring pin 232 rotates to the top of the connecting rail 241, and the distance between the spring pin 232 and the connecting tube 231 forms a gradual groove structure, the top position of the groove is the widest, and the two sides gradually narrow. When the spring pin 232 rotates to the top position of the groove, the spring pin 232 pops out from the connecting tube 231, and then the medical staff The staff member lifts the anti-falling components 3 on both sides to insert the sliding tube 331 into the connecting tube 231, so that the end of the spring pin 232 is inserted into the pin hole of the sliding tube 331, and then slowly releases the foot pedal at the bottom to drive the connecting tube 231 to reset through the spring hinge. At the same time, the spring pin 232 will drive the anti-falling guard plate 31 to tilt together, so that the two anti-falling guard plates 31 are in an eight-shaped shape. The two anti-falling guard plates 31 in an eight-shaped shape can not only prevent the child from falling off the bed when turning over, but also prevent the child from climbing over by stepping on the side walls of the anti-falling guard plates 31, thereby comprehensively improving the safety of the nursing bed when in use.

[0031] It should be noted that when the connecting tube 231 is reset, the spring pin 232 will rotate to the side of the groove body of the connecting rail 241, thereby driving the spring pin 232 to fully extend into the pin hole of the sliding tube 331, and an elastic element is arranged in the pin hole of the sliding tube 331, and the elastic element can be made of deformable materials such as rubber. When the spring pin 232 is fully extended into the pin hole of the sliding tube 331, the elastic element can lock the spring pin 232 to prevent the spring pin 232 from detaching from the sliding tube 331 when the anti-fall guard plate 31 rotates, causing the sliding tube 331 to slip off the fixed mounting frame 21, and when the medical staff lifts the anti-fall guard plate 31, the electric valve 12 opens to ensure that the rail push rod 11 can slide in the water storage pipe 10, thereby ensuring that the anti-fall guard plate 31 can rotate to avoid motion interference.

[0032] When the child touches the top support 32 on one side and presses the top support 32 hard to try to climb over the top support 32, the pressure on the connecting tube 231 increases and reaches the alarm threshold set by the pressure sensor 243. The pressure sensor 243 will feed back the detection data to the controller 4, and the controller 4 will control the movable ends of the two anti-fall electric cylinders 233 on this side to extend, thereby driving the electric cylinder connecting rod 235 to squeeze inward, and the electric cylinder connecting rod 235 will drive the spring rod 332 in the tube to extend together, so that the spring top plate 371 is squeezed out by the spring rod 332 in the tube, and the wedge block 372 at the end of the spring top plate 371 will squeeze the bottom rod 341 upward when it extends, and the top rod 342 will drive the outer end of the lever frame 323 to tilt up when it rises, and the lever frame 323 will rotate downward, thereby driving the rotating support plate 321 to tilt downward, so that the child's hand grasping the rotating support plate 321 is loosened, preventing the child from continuing to climb the guardrail.

[0033] It should be noted that the rotating support plate 321 is arranged on the inner side of the anti-falling guard plate 31, and only a very narrow gap is left between the bottom of the rotating support plate 321 and the anti-falling guard plate 31 to prevent the fingers of young children from being inserted into the gap and causing pinching accidents.

[0034] When the rotating support plate 321 tilts downward, the controller 4 will also control the movable end of the angle driving electric cylinder 9 on the other side to retract, thereby driving the rail push rod 11, the guide rail 5 and the driving rod 6 installed on the guide rail 5 to retract together, thereby driving the top of the anti-fall guard plate 31 on the other side to rotate outward, and the cover sheet 14 is pulled by the anti-fall guard plate 31, and the side where the child is standing will be lifted upward, thereby catching the child who slips off the rotating support plate 321, avoiding the occurrence of safety accidents caused by the child falling due to the rotation of the rotating support plate 321. It should be noted that when the movable end of the angle driving electric cylinder 9 is working, the electric valve 12 is always kept in a closed state to ensure the effectiveness of the extension and retraction of the movable end of the angle driving electric cylinder 9.

[0035] When the child needs care, the movable ends of the two angle-driven electric cylinders 9 will retract together, thereby driving the tops of the two anti-fall guard plates 31 to rotate outward together, thereby pulling the cover sheet 14 to fully unfold, and then lifting the child, making it easier to carry out child care work. When the child needs to be coaxed to sleep or transferred, the medical staff will open the driving handle 362 in the opposite direction, thereby driving the fixed head 364 away from the sliding tube 331, so that the anti-fall guard plate 31 no longer fixes the sliding tube 331, and then the staff will continue to lift the anti-fall guard plate 31 upward until the anti-fall guard plate 31 is lifted to the limit position, and then use the two fixed handles 36 at the bottom to fix the sliding tube 331. At this time, due to the high height of the anti-fall guard plate 31, the cover sheet 14 in the middle will pick up the child, and then the movable ends of the angle-driven electric cylinders 9 on both sides will perform the contraction and reset movement in turn, thereby driving the cover sheet 14 to shake slowly, thereby achieving The work of coaxing the child to sleep is convenient for the accompanying personnel to calm the child's emotions. When the child needs to be transported, the medical staff must first pull the front and rear sides of the cover sheet 14 to the middle position to ensure that the cover sheet 14 is clamped around the child's waist after the width is folded. Then the movable ends of the two angle-driven electric cylinders 9 are extended together, pushing the anti-fall guard plates 31 on both sides to rotate inward, thereby protecting the child between them and preventing the child from being accidentally injured during transportation. When the anti-fall guard plate 31 is at the top position and is under pressure, the anti-fall electric cylinder 233 will still extend. At this time, the spring rod 332 in the tube will push the spring push rod 351 to move inward, and then use the elastic element on the clamping plate 352 to squeeze the rotating shaft part of the drive rod 6, so that the drive rod 6 is locked with the hinge seat 7. At this time, the two anti-fall guard plates 31 and the bed body form a triangle shape, which will greatly improve the firmness of the entire medical care bed and fully protect the child inside from injury.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
