Description

Technical Field

[0001] The utility model belongs to the technical field of intelligent home equipment, and in particular relates to a multifunctional mobile nursing device. Background Art

[0002] As Chinese society enters the aging stage, the demand for long-term care for the elderly continues to grow. At present, many elderly patients and bedridden elderly people need wheelchairs to assist in activities and daily care in their lives, such as transferring in and out of bed and using the bathroom. There are various types of nursing chairs on the market that can be used to assist the elderly in activities, but they all have certain shortcomings. At present, a widely used nursing chair on the market is a hand-pushing nursing chair. This type of nursing chair is small in size and flexible in operation, which can help the elderly transfer and move, but it is difficult to change direction and operate in a small environment such as a narrow bedroom or bathroom. Another type is an electric wheelchair, which has better steering flexibility than a hand-pushing type, but is large in size, especially in a relatively small residential environment. Operation will cause certain limitations. In addition, the main function of most existing nursing chairs is to assist the elderly in activity transfer, but their functions in terms of hygienic living are relatively simple. For example, some nursing chairs can send the elderly to the bathroom door, but cannot directly transfer the elderly to the bed or toilet. For elderly people with mobility impairments, this still requires additional manpower when getting in and out of bed or using the toilet, which is not in line with the principle of independence of home care. Given the current small family care environment in China and the complexity of elderly patients' daily living and hygiene needs, traditional nursing chairs still have deficiencies in operability and functionality in these scenarios, and are unable to adapt to various complex environments and provide comprehensive care.

DETAILED DESCRIPTION

[0035] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the various embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments described in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] The embodiment of the utility model provides a multifunctional mobile nursing device, including a motion chassis 1, a seat assembly 2, an auxiliary shift assembly 3 and a toilet assembly. The utility model can not only safely and efficiently transfer the elderly to and from the bed, but also automatically navigate to send the elderly to the designated area according to the preset guide line in the room. Even in narrow spaces such as bedrooms and bathrooms, the direction and position can be flexibly changed. At the same time, it can also be switched from a wheelchair to a toilet chair at any time, which greatly solves the obstacles to the elderly's daily life and hygienic living. Specifically:

[0037] like Figures 1 to 4As shown, in this embodiment, the motion chassis 1 serves as a mounting platform for the entire nursing device, and includes a base 101 and universal wheels mounted on the base 101 for driving the entire nursing device to move freely. The base 101 is welded with steel sections to ensure the structural strength of the entire nursing device; in addition, in order to improve the flexibility of the nursing device in a narrow space, the universal wheels include four symmetrical Mecanum wheels 102, and each Mecanum wheel 102 is connected to a servo motor 103, so that the nursing device can translate laterally and turn in situ.

[0038] The seat assembly 2 includes a column 201 and a lifting part. In order to enable the seat assembly 2 to move further to the inside of the bed after moving to the edge of the bed, and to lift the user lying on the bed (or to transfer the user from the nursing device to the bed), in this embodiment, the seat assembly 2 adopts a cantilever beam structure design (that is, only one side of the base 101 is provided with a column 201, and an opening matching the thickness of the bed body is reserved above the other side of the base 101). The lifting part is fixedly installed on the column 201 to bear the weight of the user's body. Specifically, the lifting part includes a seat plate bracket 202, a backrest bracket 203 and a leg bracket 204. Among them, the seat plate bracket 202 is horizontally fixed to the top of the column 201, and the backrest bracket 203 is rotatably installed above the rear side of the seat plate bracket 202 through a first angle adjustment mechanism; the leg bracket 204 is rotatably installed below the front side of the seat plate bracket 202 through a second angle adjustment mechanism. The first angle adjustment mechanism can make the backrest support 203 rotate upward 75° from the horizontal state, and the second angle adjustment mechanism can make the leg support 204 rotate downward 70° from the horizontal state. The first angle adjustment mechanism and the second angle adjustment mechanism both use a car seat angle adjuster 205, through which the seat assembly 2 can be freely switched between a sitting position and a lying position. Furthermore, a chamfered surface is provided below the free end of the lifting portion, and the end has a rounded corner, so that the lifting portion of the seat assembly 2 in the lying position can press the mattress downward to a certain depth when moving toward the bed, thereby ensuring that the lifting portion can be better inserted into the gap between the bed and the user's body to lift the user from the bed (or transfer the user to the bed).

[0039] Furthermore, if Figure 3As shown, the column 201 is a height-adjustable electric telescopic sleeve, which includes a square stainless steel lifting sleeve 2011, a stepper motor 2012, a lifting screw 2013, and a threaded sleeve 2014. The square stainless steel lifting sleeve 2011 includes a small sleeve and a large sleeve sleeved on the small sleeve. The mounting end of the large sleeve is vertically welded to the base 101, and the seat plate bracket 202 is horizontally welded and fixed to the free end of the small sleeve. The stepper motor 2012 is fixedly installed at the bottom of the large sleeve. The lifting screw 2013 is coaxially fixedly connected to the output shaft of the stepper motor 2012. The threaded sleeve 2014 is fixedly installed in the small sleeve and is threadedly connected to the lifting screw 2013. By driving the stepper motor 2012 to rotate, the height of the seat plate bracket 202 can be adjusted to adapt to beds of different heights.

[0040] In this embodiment, the toilet assembly adopts a mobile toilet 4 with a water storage tank and a sewage collection tank. Figure 4 and Figure 5 As shown, the mobile toilet 4 is slidably mounted on the base 101 through a side shift assembly, and the side shift assembly includes a heavy-load slide rail 401, a slider, a drive motor 402, a gear 404, and a rack 403. The heavy-load slide rail 401 is fixed on the top surface of the base 101, the slider is fixedly mounted on the bottom of the mobile toilet 4 and cooperates with the heavy-load slide rail 401, the drive motor 402 is fixedly mounted on the side of the base 101 away from the user getting on and off the bed, the gear 404 is mounted on the output end of the drive motor 402, and the rack 403 is fixedly mounted on the bottom of the mobile toilet 4 and meshes with the gear 404. When it is necessary to transfer the user to get on and off the bed, the drive motor 402 drives the rack 403 to move, so that the mobile toilet 4 can be translated to the side away from the edge of the bed, thereby avoiding interference between the mobile toilet 4 and the bed body and ensuring the normal displacement of the user.

[0041] like Figures 1 to 9 As shown, in this embodiment, the auxiliary displacement component 3 is mainly used to reduce the friction during the user's displacement. Specifically, the auxiliary displacement component 3 includes a body support and a linear motion mechanism for driving the lateral displacement of the body support. The body support includes a hip support 301, a back support 302 and a leg support 303. Among them, the hip support 301 is slidably installed on the mobile toilet 4 through a first linear motion mechanism, which can be used as a toilet cover and can also support the user's buttocks; Fig.14As shown, when the user needs to use the toilet, he only needs to slightly raise the height of the column 201 so that the gravity of the user's body mainly acts on the seat support 202, and then move the hip support plate 301 to the outside of the seat support 202 through the first linear motion mechanism, and finally lower the height of the column 201. The back support plate 302 is slidably mounted on the backrest support 203 through the second linear motion mechanism to support the user's back; the leg support plate 303 is slidably mounted on the leg support 204 through the third linear motion mechanism to support the user's legs. The first linear motion mechanism, the second linear motion mechanism, and the third linear motion mechanism have the same structure.

[0042] like Figure 6 and Figure 7 As shown, taking the first linear motion mechanism as an example, the first linear motion mechanism includes a support rail 304, a slide rod 305, a first transmission screw 306, a first reduction motor 307, and a first screw nut 308. The support rail 304 is symmetrically fixedly installed on the top of the mobile toilet 4, the slide rod 305 is fixedly installed on the body support plate, and the two ends are respectively slidably matched with the front and rear support rails 304, the first reduction motor 307 is fixedly installed on the seat assembly 2, the first transmission screw 306 is connected to the output shaft of the first reduction motor 307, and the first screw nut 308 is a threaded hole opened on the slide rod 305, and the threaded hole is threadedly matched with the first transmission screw 306. By driving the first transmission screw 306 to rotate through the first reduction motor 307, the slide bar 305 can be driven to slide along the support rail 304, so that when the lifting part of the seat assembly 2 is inserted into the gap between the bed and the user's body (or when the lifting part of the seat assembly 2 is retracted after the user is transferred to the bed), the body support is transferred to the outside of the seat assembly 2 in advance, thereby reducing the friction between the care device and the user's body and making the insertion (or retraction) action of the lifting part smoother.

[0043] Since the human body has a large mass, in order to prevent the body support from sliding under the weight of the body, Figure 7As shown, as a preferred embodiment, the end of the support plate slide rail 304 on the same side as the direction of the user getting on and off the bed is also provided with an inclined rail 309 extending obliquely upward. When the body support plate needs to be retracted, the body support plate will first move obliquely downward by about 5 cm, so that most of the user's body weight is borne by the lifting part of the seat assembly 2. Correspondingly, a universal coupling 310 is also provided between the first transmission screw 306 and the output shaft of the first reduction motor 307 to ensure that the first transmission screw 306 can rotate normally when the output shaft of the first reduction motor 307 is not coaxial, so as to better drive the body support plate to move out from under the user. Furthermore, two parallel rows of rollers 311 are provided on the side of the pallet rail 304 close to the second armrest 6 (i.e., the side opposite to the direction in which the user gets on and off the bed). The two rows of rollers 311 are spaced apart by a certain gap so that the body pallet can extend out of the gap. The rollers 311 can not only provide auxiliary support for the body pallet, but also convert most of the sliding friction between the slide rod 305 and the pallet rail 304 into rolling friction, thereby greatly reducing the friction during the movement of the body pallet.

[0044] In addition, since most of the existing electric wheelchairs still require manual operation between users, especially for some elderly people with inflexible hands and feet, it is not only time-consuming and laborious to operate in a narrow area indoors, but also unsafe. Therefore, the motion chassis 1 of the multifunctional mobile nursing device provided in this embodiment is also equipped with an environmental perception sensor component. As a preferred embodiment, the environmental perception sensor component adopts a tracking camera 7 and an obstacle avoidance radar 8. There is at least one tracking camera 7, which is installed in front of the base 101 and tilted downward at a certain angle. Correspondingly, by arranging a guide line indoors, using the tracking camera 7 to capture images in real time and perform image processing, identifying specific features in the image, and then judging whether the nursing device is on the guide line through the tracking algorithm, and sending instructions to the closed-loop servo motor 103 to control the movement direction of the nursing device, the nursing device can be moved along the guided automatic driving to the user's preset destination. The obstacle avoidance radar 8 is arranged around the base 101 to timely detect obstacles on the route to further ensure driving safety.

[0045] The seat assembly 2 also includes armrests, which are arranged on both sides of the seat support 202. On the one hand, they can provide support for the user's arms, making it convenient for the user to stand up and sit down, relax the user's arms and relieve fatigue, and on the other hand, they can enhance the safety of the seat. Fig.10 and Fig.11As shown, the armrest includes a first armrest 5 and a second armrest 6. The first armrest 5 is in the same direction as the user getting on and off the bed, and is rotatably mounted on one side of the seat plate bracket 202 through a third angle adjustment mechanism. Specifically in this embodiment, the first armrest 5 includes an arm support plate 501, a main force arm 502, and a secondary force arm 503; correspondingly, the third angle adjustment mechanism includes a second reduction motor 504, a transmission shaft 505, a second transmission screw 506, and a second screw nut 507. One end of the auxiliary force arm 503 is rotationally connected to the seat plate bracket 202, and the other end is rotationally connected to the middle part of the arm support plate 501; one end of the main force arm 502 is rotationally installed on the seat plate bracket 202, and the other end is rotationally connected to the inner side of the arm support plate 501. The arm support plate 501, the main arm 502, the auxiliary force arm 503 and the seat plate bracket 202 together form a parallelogram structure, ensuring that the arm support plate 501 can always be parallel to the seat plate bracket 202 whether in a raised state or in a flat state; an extension portion 508 is also provided at the lower part of the end of the main force arm 502 connected to the seat bracket, and the extension portion 508 is integrated with the main force arm 502, and the angle between the extension portion 508 and the main force arm 502 is less than 180°. The second screw nut 507 is rotatably mounted on the extension portion 508, and the second reduction motor 504 is mounted on the seat body; one end of the second transmission screw 506 is connected to the output end of the second reduction motor 504 through a universal joint 509 and a transmission shaft 505, and the other end is threadedly connected to the second screw nut 507. By driving the second reduction motor 504, the main arm 502 can be driven to rotate, thereby erecting or laying the first armrest 5 flat. In addition, the lower side of the outer side of the arm support plate 501 is also provided with a chamfered surface and rounded corners to form a smoothly transitioned pointed head, so that the first armrest 5 can also serve as an extension of the lifting part after being laid flat, and can be better inserted into the gap between the user's body and the bed; when the seat support 202, the back support 203 and the leg support 204 are basically under the user's body, by slowly raising the first armrest 5, the user's body can be gently pushed to the side closer to the nursing device, which plays a role in straightening the user's body; when the user's body is completely straightened to the top of the lifting part, the first armrest 5 is fully raised, and can also serve as a guardrail to protect the user and prevent the user from rolling off the nursing device. The second armrest 6 is fixedly installed on the other side of the seat support 202, and the second armrest 6 is provided with operating components 601 such as an operating handle and a control button, so that the user can independently select the room he wants to go to, control the moving direction of the nursing device or switch the working mode of the nursing device.

[0046] refer to Figure 12 to Figure 14The specific method of using the multifunctional mobile nursing device provided by the utility model is as follows:

[0047] When the user needs to be transferred from the bed to the nursing device: first, the nursing staff will adjust the height of the seat assembly 2 according to the height of the bed, so that the lifting part of the seat assembly 2 is slightly lower than the height of the bed; then adjust the nursing device to a lying position and lay down the first armrest 5; drive the nursing device to move laterally in the direction close to the bed, and move the body support plate and the mobile toilet 4 to the side away from the bed, so that the entire lifting part is inserted into the gap between the user's body and the mattress; then stand up the first armrest 5, and drive the electric telescopic sleeve to slightly raise the lifting part to reduce the friction between the user's body and the mattress; then drive the nursing device to move laterally in the direction away from the bed, and at the same time move the body support plate and the mobile toilet 4 back to the seat assembly 2 until they are moved outside the bed. At this time, the body support plate and the mobile toilet 4 are also completely moved back into the seat assembly 2 to support the user's body; finally, adjust the nursing device to a sitting position, so that the user's displacement work is completed safely and comfortably, and the labor intensity of the nursing staff is also greatly reduced.

[0048] Similarly, when the user needs to be transferred from the care device to the bed: first, the height of the seat assembly 2 needs to be adjusted according to the height of the bed, so that the lifting part of the seat assembly 2 is equivalent to the height of the bed; then the care device is adjusted to a lying position; the care device is driven to move laterally in the direction close to the bed, and the body support plate and the mobile toilet 4 are moved to the side away from the bed, so that the entire lifting part moves above the mattress; then the first armrest 5 is laid flat, and the electric telescopic sleeve is driven to make the lifting part slightly drop, so that the user's body is in full contact with the mattress; finally, the care device is driven to move laterally in the direction away from the bed until it moves outside the bed, so that the user is safely and comfortably transferred from the care device to the bed.

[0049] Compared with the prior art, the utility model can directly transfer the user from the bed to the nursing chair (or from the nursing chair to the bed) without the aid of any additional transfer device, which is efficient and convenient; and during the transfer process, the entire chair body is located directly under the user's body, which has better stability.

[0050] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view. The scope of the present invention is defined by the appended claims, rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any figure mark in the claims should not be regarded as limiting the claims involved.

[0051] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
