Description

Technical Field

[0001] This invention relates to the field of patient care technology, specifically to an auxiliary device for the care of elderly patients. Background Technology

[0002] As people age, their bodies and tissues undergo gradual changes, much like their appearance. These changes are less noticeable in youth but often become rapid and significant in old age, accompanied by changes in physiological function. The elderly's own regulatory mechanisms become increasingly insensitive, imprecise, and slow. Due to weakness in the limbs and trunk, elderly patients often require bed rest, are unable to move freely, and experience a decline in bodily functions, making some daily activities impossible and requiring the assistance of caregivers.

[0003] Due to declining limb function in some elderly patients, they typically lie in bed during their convalescence. When they need to eat, they sit up and set up a table on the bed to place their food. Currently, the tables on existing elderly patient care beds generally require manual setup by caregivers. After meals, if caregivers do not promptly clean up the food waste and remove the table, it is difficult for the elderly to lie down and rest, making the device inconvenient to use. Furthermore, leaving food waste outside for extended periods attracts flies and insects, especially in summer, easily producing unpleasant odors that affect the rest and health of the elderly in the ward. Therefore, we propose an assistive device for elderly patient care. Summary of the Invention

[0004] The purpose of this invention is to provide an auxiliary device for elderly patient care that facilitates automatic adjustment and storage of the patient table and automatic collection of post-meal waste, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a nursing aid for elderly patients, comprising a bed frame, a table, a moving mechanism, a collecting mechanism, and an auxiliary mechanism. One end of the bed frame is fixedly connected to a headboard, and a bed board is fixedly connected to the bed frame. The moving mechanism is mounted on the bed frame and is used to control the table to move horizontally from the foot of the bed to the desired position in the middle when the table is needed, and to flip it to a vertical position for storage after use. The collecting mechanism includes a collecting box fixedly mounted on the end of the bed frame away from the headboard, with a rotating shaft fixedly connected to the collecting box. A flipping box is rotatably connected to the rotating shaft. The collecting mechanism is used to open the flipping box by linkage each time the table moves to the foot of the bed to collect the waste on the table, and to reset and close the flipping box after the table flips to a vertical position. The auxiliary mechanism is mounted on the bed frame and is used to assist the patient in sitting up and lying down, facilitating automatic adjustment and storage of the table and automatic collection of post-meal waste.

[0006] Preferably, the moving mechanism includes brackets fixedly installed on both sides of the tabletop, guardrails fixedly connected to both sides of the bed frame, a first sliding groove and a second sliding groove provided on the guardrails, and an inclined groove connected to one end of the first sliding groove provided on the guardrails. A first slider fixedly connected to both the first sliding groove and the inclined groove is slidably connected to one side of the brackets, and a second slider fixedly connected to the second sliding groove is slidably connected to one side of the brackets. The bed frame is provided with a driving component for moving the brackets, which facilitates the adjustment of the tabletop's flipping and movement.

[0007] Preferably, the driving component includes a guide rail fixedly mounted on the bed frame, a guide rod slidably connected in the horizontal direction within the guide rail, a lifting groove provided in the guide rod, a lifting rod slidably connected in the lifting groove, a drive shaft fixedly connected to the bracket rotatably connected to the side of the lifting rod, a first lead screw rotatably connected within the guide rail, the first lead screw passing through the guide rod and threadedly connected to the guide rod, and a drive motor fixedly connected within the guide rail, the output end of the drive motor being coaxially fixedly connected to the first lead screw to facilitate the movement of the bracket.

[0008] Preferably, the collection mechanism includes fixing buckles fixedly installed on both sides of the bed frame, and each of the two sets of fixing buckles is fixedly connected to an elastic pull rope fixedly connected to the side of the flip box. The bed frame is provided with a linkage component for pushing the flip box open when the table is close to the flip box and driving the flip box to flip and reset after the table becomes vertical, so as to facilitate the collection of garbage on the table.

[0009] Preferably, the linkage includes a guide box fixedly installed on the end of the guide rail away from the drive motor. A sliding block is slidably connected in the horizontal direction inside the guide box. A push box is slidably connected in the horizontal direction on the outer wall of the guide box. A first tension spring fixedly connected to the bed frame is fixedly connected to one side of the push box. A second lead screw is rotatably connected in the guide box and coaxially fixedly connected to the first lead screw. The second lead screw passes through the sliding block and is threadedly connected to the sliding block. The sliding block is provided with a pusher for pushing the push box to slide when the sliding block slides towards the foot of the bed. This facilitates pushing the flip box open when the table is close to the flip box and driving the flip box to flip and reset after the table becomes vertical.

[0010] Preferably, the pushing component includes a first trapezoidal block installed inside the sliding block, a first limiting groove being formed inside the sliding block, the first trapezoidal block being slidably connected to the first limiting groove in a vertical direction, a second spring being fixedly connected to the upper side of the first trapezoidal block and fixedly connected to the first limiting groove, a second limiting groove being formed inside the pushing box, a second trapezoidal block being slidably connected to the second limiting groove in a vertical direction, the inclined surface of the first trapezoidal block being opposite to the inclined surface of the second trapezoidal block, and a control component being provided in the second limiting groove for pushing the second trapezoidal block upward and pushing the second trapezoidal block downward when the table becomes vertical, so as to facilitate pushing the pushing box to slide when the sliding block slides towards the foot of the bed.

[0011] Preferably, the control component includes a third spring fixedly installed in the second limiting groove. An L-shaped block is fixedly connected to the upper end of the third spring. The L-shaped block is fixedly connected to the bottom surface of the second trapezoidal block. The top of the L-shaped block is higher than the top of the push box, which is used to sense the pushing force of the table, so as to push the second trapezoidal block to move upward and push the second trapezoidal block to press downward when the table becomes vertical.

[0012] Preferably, the auxiliary mechanism includes a rotating plate hinged to one end of the bed board near the head of the bed, and an electric telescopic rod rotatably connected to the bed frame for pushing the rotating plate to flip, so as to facilitate the patient to sit up and lie down.

[0013] Preferably, a top plate is fixedly connected to the upper end of the flip box, and a handle is fixedly connected to the top plate, which facilitates the sealing of the collection box and makes it convenient for caregivers to open the flip box.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. This invention provides an auxiliary nursing device for elderly patients. When the patient needs to sit up for meals, an electric telescopic rod pushes a rotating plate to rotate, allowing the elderly patient to sit up. Simultaneously, a drive motor is activated, causing the first lead screw to rotate. This causes the guide rod to slide towards the head of the bed within the guide rail, which in turn pushes the lifting rod and the support to slide. Since the distance between the first and second sliders is exactly the vertical distance between the first and second sliding grooves, it ensures that when the support slides, the first slider first slides into the first sliding groove, and then the support and the table slide horizontally together to a suitable position in the middle of the bed frame. At this time, the positions of the first and second sliders are limited by the first and second sliding grooves, preventing them from deflecting or wobbling. After the table is used, the drive motor is activated to rotate in the opposite direction, causing the guide rod to move in the opposite direction and the first slider to slide into the inclined groove, causing it to rotate 90°, turning the table into a vertical position and storing it at the foot of the bed. The operation is convenient, requires no manual placement, and the table is stored reasonably without taking up much space.

[0016] 2. The present invention provides a nursing aid for elderly patients. When the table moves towards the head of the bed, the first lead screw drives the second lead screw to rotate, thereby driving the sliding block to slide towards the head of the bed. During this process, the inclined surface of the first trapezoidal block will touch the inclined surface of the second trapezoidal block and push against each other, extending and retracting within the first and second limiting grooves without getting stuck. After the table is used, the elderly patient places their meal waste on the table and moves it with the table. At this time, the first lead screw drives the second lead screw to rotate in the opposite direction, causing the sliding block to slide in the opposite direction. When the side of the first trapezoidal block abuts against the side of the second trapezoidal block, it will push the second trapezoidal block to move together with the push box. This causes the pusher box to push the side of the flip box, which rotates around the pivot to open the flip box. When the table is flipped to a vertical position, the upper opening between the flip box and the collection box is fully open, facilitating the collection of post-meal waste. When the table is in a vertical position, it will hit the upper end of the L-shaped block, causing the second trapezoidal block to move down and compress the third spring, thereby releasing the contact with the side of the first trapezoidal block. Then, driven by the elastic pull rope, the flip plate rotates in the opposite direction to close the opening between the collection boxes, realizing automatic collection and closing of waste. This prevents post-meal waste from attracting flies and insects, which can easily produce odors in summer and affect the rest and health of the elderly in the ward.

[0017] 3. This invention provides an auxiliary nursing device for elderly patients. By placing a collection box at the foot of the bed, the impact of garbage on the patient is greatly reduced. The patient is kept away from the garbage, resulting in fresher air and aiding recovery. The upper edge of the garbage bag can be fixed to the side of the collection box and top plate, facilitating direct dumping of tabletop garbage into the bag. When the flip box rotates to a vertical position, the top plate closes the opening of the garbage bag, reducing odor emissions. The collection box and flip box occupy minimal space when closed, not obstructing movement at the foot of the bed. Caregivers can open the flip box by pulling a handle to remove garbage and replace it with a clean bag. The opening and closing of the flip box is controlled only by an elastic cord, allowing for both manual and automatic closure. Patients typically use metal or plastic tableware that is not easily broken when eating in the hospital. This can be placed directly on the table and dumped into the garbage bag in the collection box at the foot of the bed, allowing patients to move the table and collect tableware immediately after meals without waiting for caregivers.

[0030] Please see Figure 1-10This invention provides a technical solution: a nursing aid for elderly patients, comprising a bed frame 1, a table 2, a moving mechanism 5, a collecting mechanism 6, and an auxiliary mechanism 10. One end of the bed frame 1 is fixedly connected to a headboard 3, and a bed board 4 is fixedly connected to the bed frame 1. The moving mechanism 5 is mounted on the bed frame 1 and is used to control the table 2 to move horizontally from the foot of the bed to the desired position in the middle when needed, and to move it to the foot of the bed and flip it into a vertical position for storage after use. The collecting mechanism 6 includes a collecting box 7 fixedly mounted on the end of the bed frame 1 away from the headboard 3. A rotating shaft 8 is fixedly connected to the collection box 7, and a flipping box 9 is rotatably connected to the rotating shaft 8. The collection mechanism 6 is used to rotate and open the flipping box 9 each time the table 2 moves to the foot of the bed to collect the garbage on the table 2, and to reset and close the flipping box 9 after the table 2 flips to a vertical position. The auxiliary mechanism 10 is installed on the bed frame 1 to assist the patient in sitting up and lying down. The auxiliary mechanism 10 includes a rotating plate 43 that is hinged to the end of the bed board 4 near the head of the bed 3. An electric telescopic rod 44 for pushing the rotating plate 43 to flip is rotatably connected to the bed frame 1.

[0031] The moving mechanism 5 includes a bracket 11 fixedly installed on both sides of the table 2. A guardrail 12 is fixedly connected to both sides of the bed frame 1. The guardrail 12 has a first sliding groove 13 and a second sliding groove 14. The guardrail 12 has an inclined groove 15 that communicates with one end of the first sliding groove 13. A first slider 16 that is slidably connected to both the first sliding groove 13 and the inclined groove 15 is fixedly connected to one side of the bracket 11. A second slider 17 that is slidably connected to the second sliding groove 14 is fixedly connected to one side of the bracket 11. Both the first slider 16 and the second slider 17 are cylindrical. The bed frame 1 is provided with a driving component 18 for moving the bracket 11.

[0032] The drive unit 18 includes a guide rail 19 fixedly mounted on the bed frame 1. A guide rod 20 is slidably connected in the horizontal direction inside the guide rail 19. A lifting groove 21 is opened in the guide rod 20. A lifting rod 22 is slidably connected in the lifting groove 21. A drive shaft 23 fixedly connected to the bracket 11 is rotatably connected to the side of the lifting rod 22. A first lead screw 24 is rotatably connected inside the guide rail 19. The first lead screw 24 passes through the guide rod 20 and is threadedly connected to the guide rod 20. A drive motor 25 is fixedly connected inside the guide rail 19. The drive motor 25 is preferably a YYHS-40 model. The output end of the drive motor 25 is coaxially fixedly connected to the first lead screw 24.

[0033] The collection mechanism 6 includes fixing buckles 26 fixedly installed on both sides of the bed frame 1. Each of the two sets of fixing buckles 26 is fixedly connected to an elastic pull rope 27 fixedly connected to the side of the flip box 9. The top end of the flip box 9 is fixedly connected to a top plate 45, and a handle 46 is fixedly connected to the top plate 45. The bed frame 1 is provided with a linkage component 28 for pushing the flip box 9 open when the table 2 is close to the flip box 9 and driving the flip box 9 to flip and reset after the table 2 becomes vertical.

[0034] The linkage component 28 includes a guide box 29 fixedly installed on the end of the guide rail 19 away from the drive motor 25. A sliding block 30 is slidably connected in the horizontal direction inside the guide box 29. A push box 31 is slidably connected in the horizontal direction on the outer wall of the guide box 29. A first tension spring 32 fixedly connected to the bed frame 1 is fixedly connected to one side of the push box 31. A second lead screw 33 is rotatably connected in the guide box 29 and coaxially fixedly connected to the first lead screw 24. The second lead screw 33 passes through the sliding block 30 and is threadedly connected to the sliding block 30. A pusher 34 is provided on the sliding block 30 to push the push box 31 to slide when the sliding block 30 slides towards the foot of the bed.

[0035] The pusher 34 includes a first trapezoidal block 35 installed in the sliding block 30. A first limiting groove 36 is provided in the sliding block 30. The first trapezoidal block 35 and the first limiting groove 36 are slidably connected in the vertical direction. A second spring 37 is fixedly connected to the upper side of the first trapezoidal block 35 and fixedly connected to the first limiting groove 36. A second limiting groove 38 is provided in the pusher box 31. A second trapezoidal block 39 is slidably connected in the vertical direction in the second limiting groove 38. The inclined surface of the first trapezoidal block 35 is opposite to the inclined surface of the second trapezoidal block 39. A control element 40 is provided in the second limiting groove 38 for pushing the second trapezoidal block 39 upward and pushing the second trapezoidal block 39 downward when the table 2 becomes vertical.

[0036] The control component 40 includes a third spring 41 fixedly installed in the second limiting groove 38. An L-shaped block 42 is fixedly connected to the upper end of the third spring 41. The L-shaped block 42 is fixedly connected to the bottom surface of the second trapezoidal block 39. The top of the L-shaped block 42 is higher than the top of the push box 31 and is used to sense the pushing force of the table 2.

[0037] When the patient needs to sit up for a meal, the electric telescopic rod 44 pushes the rotating plate 43 to flip, allowing the elderly patient to sit up. Simultaneously, the drive motor 25 is activated, causing the first lead screw 24 to rotate. This causes the guide rod 20 to slide towards the headboard 3 within the guide rail 19, thus pushing the lifting rod 22 and the support 11 to slide. Since the distance between the first slider 16 and the second slider 17 is exactly the vertical distance between the first slide groove 13 and the second slide groove 14, it is ensured that when the support 11 slides, the first slider 16 will first slide from the inclined groove 15 into the first slide groove 13, and then... The bracket 11 and the table 2 slide horizontally to a suitable position in the middle of the bed frame 1. At this time, the positions of the first slider 16 and the second slider 17 are limited by the first slide groove 13 and the second slide groove 14, so that they will not deflect or shake. When the table 2 is finished, the drive motor 25 is started to rotate in the opposite direction, which will cause the guide rod 20 to move in the opposite direction and cause the first slider 16 to slide into the inclined groove 15 and rotate 90°, so that the table 2 is put into a vertical position and stored at the foot of the bed. The operation is convenient and there is no need to put it in manually. The table 2 is stored reasonably and does not take up space.

[0038] When the tabletop 2 moves towards the headboard 3, the first lead screw 24 drives the second lead screw 33 to rotate, thereby driving the sliding block 30 to slide towards the headboard 3. During this process, the inclined surface of the first trapezoidal block 35 will touch the inclined surface of the second trapezoidal block 39 and push against each other within the first limiting groove 36 and the second limiting groove 38 without getting stuck. After the tabletop 2 is used, the elderly patient places the food waste on the tabletop 2 and moves it with the tabletop 2. At this time, the first lead screw 24 drives the second lead screw 33 to rotate in the opposite direction, causing the sliding block 30 to slide in the opposite direction. When the side of the first trapezoidal block 35 abuts against the side of the second trapezoidal block 39, it will push the second trapezoidal block 39 and the push box 31 to move together, thereby making Pushing the side of the flip box 9 by pushing the box 31 will rotate the flip box 9 around the rotating shaft 8 to open it. When the table 2 is flipped to a vertical position, the upper opening between the flip box 9 and the collection box 7 will be opened to the maximum, which is convenient for collecting post-meal waste. When the table 2 is in a vertical position, it will hit the upper end of the L-shaped block 42, causing the second trapezoidal block 39 to move down and compress the third spring 41, thereby releasing the contact with the side of the first trapezoidal block 35. Then, driven by the elastic pull rope 27, the flip plate will rotate in the opposite direction to close the opening between the collection boxes 7, realizing automatic collection and closing of waste, preventing post-meal waste from attracting flies and insects, especially in summer when it is easy to produce odors that affect the rest and health of the elderly in the ward.

[0039] It is worth noting that the collection box 7, located at the foot of the bed, significantly reduces the impact of trash on the patient. Keeping the patient away from trash allows for fresher air, aiding in recovery. The upper edge of the trash bag can be fixed to the side of the collection box 7 and the top plate 45, facilitating direct disposal of tabletop trash into the bag. When the flip box 9 rotates to a vertical position, the top plate 45 closes the opening of the trash bag, reducing odor emissions. The collection box 7 and flip box 9 occupy minimal space when closed, not obstructing movement at the foot of the bed. Caregivers can open the flip box 9 by pulling the handle 46 to remove trash and replace it with a clean bag; the opening and closing of the flip box 9 is only controlled by the elastic cord 27. The pull mechanism facilitates manual opening and automatic closing. The tableware used by patients when dining in the hospital is generally made of metal or plastic, which are not easily broken. These tableware can be placed directly on the table 2 and poured into the garbage bag in the collection box 7 at the foot of the bed for collection. This allows patients to operate the table 2 to move and collect tableware directly after finishing their meal, without waiting for the arrival of nursing staff, which is more convenient. The first tension spring 32 is used to pull the push box 31 back to its original position. The guide box 29 is provided with a sliding groove that slides and limits the push box 31 in the horizontal direction. The end of the sliding groove near the head of the bed is located in the middle of the guide box, which facilitates the push box 31 to be resisted while allowing the sliding block 30 to pass over the push box 31 and reach the side near the head of the bed.

[0040] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
