Description

Technical Field

[0001] The invention relates to the technical field of medical care, and in particular to a belt-type flap care bed. Background Art

[0002] Paralyzed patients or patients with brain tissue damage who have lost the ability to move independently cannot turn over or move their bodies in bed by themselves and must be cared for by a caregiver throughout the process to help the patients turn over and adjust their positions frequently to facilitate their eating and treatment, and to prevent the patients from developing bedsores due to staying in one position for a long time.

[0003] Since paralyzed patients cannot cooperate with their caregivers to turn over or move their bodies independently, the caregivers have to use a lot of strength to turn over or move the paralyzed patients. It is difficult for caregivers to turn over or change the position of paralyzed patients with heavy weight. It is often the case that paralyzed patients can only turn over left or right on the bed, and it is impossible or difficult to move the patient's body. After turning over, the patient's body position is often too far inside or too far outside, which is not conducive to nursing or treatment by nursing staff and also easily puts the patient in danger of falling off the bed.

[0037] See also Figure 1-15 The present invention relates to a belt-type flap nursing bed, comprising a bed body 1, a fixed plate conveyor belt assembly, a flip plate conveyor belt assembly, a conveyor belt translation motion mechanism and a flip motion mechanism.

[0038] The flip plate conveyor belt assembly is symmetrically arranged on the left and right sides of the fixed plate conveyor belt assembly, and the fixed plate conveyor belt assembly includes a fixed plate frame 2, and fixed plate shafts 3 are provided on both sides of the fixed plate frame 2. The fixed plate conveyor belt 4 is wound around the fixed plate shafts 3. The fixed plate frame 2 is connected to the bed 1 through the fixed frame fixing block 33, and the fixed plate shaft 3 is rotatably arranged on the fixed plate frame 2.

[0039] The flip plate conveyor belt assembly includes a flip plate frame 5, a flip plate fixed shaft 6 is provided inside the flip plate frame 5, and a flip plate swing shaft 7 is provided outside the flip plate frame 5, the flip plate fixed shaft 6 is rotatably arranged on the bed body 1, and the flip plate conveyor belt 8 is wound around the flip plate fixed shaft 6 and the flip plate swing shaft 7.

The translation input shaft 18 is connected to the translation handle or the translation reduction motor, and the chain 17 is wound around the driving sprocket 14, the passive sprocket 15 and the tensioning sprocket 16 at the same end.

[0041] The flip motion mechanism is arranged below the flip plate conveyor belt assembly, and the two flip motion mechanisms are symmetrical. The flip motion mechanism includes a worm 19, a worm wheel 20, a sixth gear 21, a synchronous shaft 22 and an arc-shaped rack 23. The front and rear sixth gears 21 are arranged at both ends of the synchronous shaft 22. The worm wheel 20 is arranged on one end of the synchronous shaft 22. The worm wheel 20 is meshed with the worm 19. The worm 19 is connected to a flip handle or a flip reduction motor. Two arc-shaped racks 23 are fixed at both ends of the flip plate frame 5. Each arc-shaped rack 23 is meshed with the corresponding sixth gear 21. When flipping, the arc-shaped rack 23 drives the flip plate frame and the flip plate conveyor belt to flip with the flip plate fixed axis as the rotation center. The flip plate conveyor belt assembly can flip upward by 0-90°.

[0042] The worms 19 of the left and right tilting motion mechanisms are connected via a transition shaft 24 .

[0043] The fixed plate frame 2 and the flip plate frame 5 are both provided with a transmission belt support plate 25 to support each conveyor belt. The transmission belt support plate 25 is respectively located on the inner side of the upper side of the fixed plate conveyor belt 4 and the flip plate conveyor belt 8, so as to realize the translational support of the upper surface of the conveyor belt on the objects (human body). The flip plate conveyor belt assembly can realize the flipping motion (0-90°) around the axis fixed in position (relative to the bed) on each flip frame through respective worm gears, gear transmissions, etc.

[0044] The fixed plate conveyor belt 4 and the flip plate conveyor belt 8 are both tensioned by a belt tensioning device, which is respectively arranged at the bottom edge of the fixed plate conveyor belt 4 and the flip plate conveyor belt 8. The belt tensioning device includes a belt tensioning plate 26, a belt tensioning seat 27 and a belt tensioning screw 28. Belt tensioning seats 27 are provided at both ends of the belt tensioning plate 26. The belt tensioning seat 27 is connected to the belt tensioning plate 26 through the belt tensioning screw 28, wherein the belt tensioning seat 27 of the fixed plate conveyor belt 4 is fixed on the fixed plate frame 2, and the belt tensioning seat 27 of the flip plate conveyor belt 8 is fixed on the flip plate frame 5.

[0045] The fixed plate conveyor belt 4 and the flip plate conveyor belt 8 are composed of multiple conveyor belts, and each conveyor belt is provided with a synchronous toothed belt at both ends. The fixed plate shaft 3, the flip plate fixed shaft 6 and the flip plate swing shaft 7 are provided with synchronous pulleys 29 at both ends of the synchronous toothed belts corresponding to the synchronous toothed belts. The synchronous pulleys 29 are engaged with the synchronous toothed belts, and the teeth of the synchronous toothed belts at both ends of the conveyor belts are aligned.

[0046] The fixed plate shaft 3, the flip plate fixed shaft 6 and the flip plate swing shaft 7 are each formed by connecting a plurality of short shafts via couplings.

[0047] The third gear 11 is connected to the fixed plate shaft 3 via a one-way bearing 30 .

[0048] A support bar 31 is provided between the fixed plate conveyor belt 4 and the flip plate conveyor belt 8. The support bar 31 is fixed on the bed body 1. A short side 31.1 is provided on the top of the support bar 31. The short side is arranged toward one side of the fixed plate conveyor belt 4 to reduce the gap between the fixed plate conveyor belt 4 and the flip plate conveyor belt 8.

[0049] A limit block 32 is disposed at one end of the arc-shaped rack 23 away from the flip plate frame 5 to ensure that the arc-shaped rack 23 is meshed with the sixth gear 21 .

[0050] 1. Translation of the upper surface of the conveyor belt

[0051] The fixed plate frame 2 is fixed to the bed 1, and several conveyor belts with the same parameters and synchronous toothed belts on both sides are meshed with the corresponding synchronous pulleys on the two fixed plate shafts 3 fixed on the frame through bearings to form a synchronous belt transmission. Since the two fixed plate shafts 3 are too long, considering assembly and other factors, the middle of each long shaft can be connected by a coupling (the same applies to the flip plate). The two fixed plate shafts 3 on the fixed plate frame 2 are driven by the same power through their own shaft end gears. In order to avoid transmission interference, the front ends of the two fixed plate shafts 3 on the fixed plate frame 2 are equipped with a one-way torque transmission gear (using an overrunning mechanism such as a one-way bearing, etc.), but the torque transmission direction is opposite.

[0052] 2. Flipping movement of the flip plate conveyor belt

[0053] The flip plate frame 5 can rotate around the axis position of the flip plate relative to the flip plate fixed shaft 6 fixed to the bed body. The principle of the flip plate conveyor belt transmission mechanism is the same as that of the fixed plate conveyor belt. It is also a conveyor belt with several parameters and synchronous toothed belts on both sides, which are meshed with the corresponding synchronous belt wheels on the flip plate fixed shaft 6 and the flip plate swing shaft 7 fixed by bearings to form a synchronous belt transmission. The flip plate swing shaft 7 on the flip plate frame 5 can rotate around the flip plate fixed shaft 6. The flip plate swing shaft 7 is called an idle shaft, and the flip plate fixed shaft 6 is a driving shaft.

[0054] The difference between a fixed plate conveyor and a flip plate conveyor is that the fixed plate frame of a fixed plate conveyor is fixed on the bed, while the flip plate frame of a flip plate conveyor can flip relative to a long axis on it. The flipping motion of the left and right flip plates is independent of each other, and the flipping motion of the left and right flip plates is realized by their own independent reduction motors (electric), worm gears, synchronous gear transmission, etc. The translational motion of the upper surface of the fixed plate conveyor and the flip plate conveyor are connected to the same power source through gear transmission, chain transmission, etc., so that the fixed plate conveyor and the flip plate conveyor can make translational motion synchronously at the same time.

[0055] The translation working principle of the present invention is as follows:

[0056] The translation input shaft 18 is driven manually or electrically to rotate, driving the fourth gear 12 and the driving sprocket 14, and the tensioning sprocket 16 tensions the chain 17, and the chain 17 simultaneously drives the passive sprockets 15 on the left and right sides to rotate, and the passive sprockets 15 on both sides respectively drive their coaxial second gears 10, and the second gear 10 simultaneously drives the first gear 9 and the third gear 11, driving the respective flip plate fixed shafts 6, the flip plate swing shaft 7 and the fixed plate shaft 3 on the fixed plate conveyor belt assembly of the left and right flip plate conveyor belt assemblies, and the flip plate fixed shaft 6, the flip plate swing shaft 7 and the fixed plate shaft 3 drive each conveyor belt to perform left and right translation movement through the synchronous pulley.

[0057] In order to solve the transmission interference of the fixed plate shaft 3 of the fixed plate conveyor belt, a one-way bearing is installed between the third gear 11 and the fixed plate shaft 3 to achieve Fig.12 Arrow direction of transcendence.

[0058] The flip working principle of the present invention:

[0059] The worm 19 is driven manually or electrically, and the two sixth gears 21 are connected through the synchronization shaft 22, and the two arc-shaped racks 23 before and after the right flip transmission component are synchronously driven to realize the flipping of the left or right flip plate conveyor belt around the flip plate fixed shaft 6, thereby completing the patient turning function.

[0060] The manual mode of the present invention is that the nursing staff manually operates the rocker arm corresponding to the function of the "belt-type flap nursing bed" to complete the required nursing functions for the paralyzed patient, such as left translation, right translation, left turning, right turning, etc.; the electric mode "belt-type flap nursing bed" can be manually operated by the patient himself to operate the electrical control box or remote control to select the working state of the "belt-type flap nursing bed", such as left translation, right translation, left turning, right turning, etc. The paralyzed patient can complete the body position adjustment and control by himself, which can reduce the dependence on the nursing staff or do not need others to take care of it, so as to reduce the psychological pressure and economic pressure of the paralyzed patient. It can greatly improve the quality of life of the paralyzed patients and reduce the work intensity of the nursing staff or relatives. The invention of the "belt-type flap nursing bed" of the present invention will bring good news to the paralyzed patients, especially the elderly who have lost their ability to move.

[0061] The present invention can be widely applied to medical units, nursing homes, rehabilitation centers and other departments, greatly improving the quality of life of these patients, reducing the labor intensity of nursing staff, and alleviating the burden on relatives and society.

[0062] The process of using the present invention is:

[0063] 1. Translational movement: The conveyor belt is driven manually or electrically by nursing staff to enable the paralyzed patient lying in bed to complete left and right translational movement.

[0064] 2. Turning over: There are two ways to do it

[0065] (1) First, the paralyzed patient is placed supinely in the middle of the nursing bed, and the conveyor belt transmission mechanism is driven to move the paralyzed patient supinely to the left or right flip plate conveyor belt that can be flipped around a fixed axis. The flip mechanism of the flip plate conveyor belt on the left or right side is driven manually or electrically by the nursing staff, so that the paralyzed patient can turn over with the help of the flipping force of the flip plate conveyor belt. After the turning is completed and stable, the flip plate conveyor belt can be flipped to a horizontal position.

[0066] (2) The flipping mechanism of the selected flipping plate conveyor belt (left-side flipping or right-side flipping) is first manually or electrically driven by the nursing staff to flip it to the correct position (≤90°), and then the manual or electrically driven translation conveyor belt transmission mechanism is used to translate the paralyzed patient's body to the flipping plate conveyor belt where the flipping has been completed, and the translation conveyor belt transmission mechanism is continued to be driven until the patient is turned over.

[0067] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
