Description

Auxiliary displacement device with multiple postures

The present invention relates to a nursing assistive device, in particular to a multi-position assistive displacement device that can assist in caring for bedridden persons.

According to estimates, Taiwan is expected to enter an "Ageing Society" with a population of 65 and above accounting for 20.8% by the end of 2025. As the elderly population increases, the number of bedridden patients will inevitably increase; in addition, there are patients who need to stay in bed for a long time due to disability caused by illness or accidents. Therefore, the various care needs of bedridden patients will bring major challenges to the care system.

First, long-term bedridden people face a variety of health risks, including pressure sores, muscle atrophy and joint stiffness, so regularly changing the posture of bedridden people can not only promote blood circulation, but also reduce pressure points and reduce the incidence of complications. Secondly, in response to care needs such as lying, bathing or defecation, if bedridden people can present corresponding body postures such as lying, sitting or squatting, it will not only be easier to care for, but also improve the comfort of bedridden people, and help restore or maintain the body functions of bedridden people, and improve the quality of life of bedridden people.

However, the above-mentioned changes in the bedridden person's posture often require caregivers to laboriously pull, support, or even carry the bedridden person, which in turn brings occupational injuries to the caregivers. For this reason, many European and American countries have begun to promote the concept of "No-Lift Policy", prohibiting caregivers from moving bedridden people by hand, and requiring the use of transfer machines or related mobility assistive devices to protect the health of caregivers and reduce occupational injuries caused by moving bedridden people; this also means that more efficient assistive devices are needed to assist caregivers in adjusting the bedridden person's posture.

However, many of the current mobility assistive devices on the market only have basic mobility functions; for example, a mobility belt can only be used for standing up and turning, a mobility slide can only be used for sitting or lying down horizontally depending on the type, a mobility turntable or standing lift can only be used for standing up and turning, and a suspension lift can only be used for hanging and turning, etc. In short, there is currently no single known mobility assistive device that can meet the posture needs of bedridden people in different situations.

In view of the above shortcomings of the known technology, the inventor felt that it was not perfect, so he devoted all his energy to research and overcome it, and then developed a multi-position auxiliary displacement device that can assist bedridden people to present body postures such as lying, sitting or squatting.

To achieve the above and other purposes, the present invention provides a multi-position auxiliary displacement device, comprising: a base frame, including a base and a stand, the base and the stand together forming a body accommodation space; a first lifting unit, which can be lifted and lowered on the stand and has an upper body support rod located in the body accommodation space; a second lifting unit, which can be lifted and lowered on the stand and has a lower body support rod located in the body accommodation space; and an elastic bearing member, which is located in the body accommodation space and connects the upper body support rod and the lower body support rod.

In the above-mentioned multi-position auxiliary displacement device, the first lifting unit and the second lifting unit can be arranged adjacent to each other on the stand, and the upper body support rod and the lower body support rod can be arranged generally in parallel.

In the above-mentioned multi-position auxiliary displacement device, the elastic support member can be an elastic net.

In the above-mentioned multi-position auxiliary displacement device, the first lifting unit may include a first moving seat, the first moving seat can be driven to move up and down relative to the stand, and the upper body support rod can be connected to the first moving seat.

In the above-mentioned multi-position auxiliary displacement device, the first lifting unit may further include a handlebar, which is foldably connected to the first moving seat, and the handlebar is located between the upper body support rod and the lower body support rod.

The above-mentioned multi-position auxiliary displacement device may further include a microcontroller unit. A physiological signal measuring unit may be provided on the handle. The microcontroller unit is electrically connected to the physiological signal measuring unit to receive the measurement results of the physiological signal measuring unit.

In the above-mentioned multi-position auxiliary displacement device, the upper body support rod and the lower body support rod can be extended and retracted laterally toward the relative outside.

The above-mentioned multi-position auxiliary displacement device may further include an image capture unit and a microcontroller unit. The microcontroller unit is electrically connected to the image capture unit. The image capture unit is suitable for taking an image of the bedridden person toward the accommodation space. After receiving the image, the microcontroller unit analyzes the height of the bedridden person, or identifies the position of the upper back and back knees of the bedridden person, so as to control the upper body support rod and/or the lower body support rod to automatically extend and retract in the horizontal direction to adjust the relative distance between the upper body support rod and the lower body support rod in the horizontal direction.

The above-mentioned multi-position auxiliary displacement device may further include a microcontroller unit. The base frame is provided with a weight measuring unit. The microcontroller unit is electrically connected to the weight measuring unit to receive the measurement result of the weight measuring unit.

In the above-mentioned multi-position auxiliary displacement device, the base can have two extension rods respectively connected to the two ends of a horizontal rod, the two extension rods are opposite to each other, the horizontal rod is opposite to the opening of the base, the stand can extend upward from the horizontal rod, and the accommodation space is formed in front of the stand and above the two extension rods.

In the above-mentioned multi-position auxiliary displacement device, the base frame may include a mobile module, the mobile module may have two front wheels and at least one rear wheel, the two front wheels may be respectively embedded in the corresponding extension rods, the rear wheel may be adjacent to the crossbar, and the size of the front wheel may be smaller than that of the rear wheel.

In the above-mentioned multi-position auxiliary displacement device, the rear wheel can rotate in multiple directions and can have a self-locking function.

Thus, the multi-position auxiliary displacement device of the present invention can assist bedridden people to change various body postures in response to care needs such as lying in bed, bathing or excretion, etc., with a simple structure, which can not only effectively reduce the workload of caregivers and improve work efficiency, but also enable bedridden people to maintain good blood circulation, reduce pressure points and reduce the incidence of bed complications. In addition, the multi-position auxiliary displacement device can also make bedridden people feel safe and comfortable, reduce their struggles or movements, and thus reduce accidental injuries that may be caused during transportation. Therefore, this device not only improves the quality of life of bedridden people, but also ensures the work safety of caregivers, reduces occupational injuries and improves work efficiency. In addition to assisting in the transportation of bedridden people, this device can also assist bedridden people in simple rehabilitation exercises, and is extremely practical.

In order to fully understand the purpose, features and effects of the present invention, the present invention is described in detail through the following specific embodiments and the attached drawings, as follows:

Please refer to Figures 1 and 2, which are a preferred embodiment of the multi-position auxiliary displacement device of the present invention. The multi-position auxiliary displacement device includes a base frame 1, a first lifting unit 2, a second lifting unit 3 and an elastic supporting member 4.

The base frame 1 includes a base 11 and a stand 12, and the base 11 and the stand 12 together form a living space S. The first lifting unit 2 is liftably disposed on the stand 12 and has an upper body support rod 21 located in the living space S. The second lifting unit 3 is liftably disposed on the stand 12 and has a lower body support rod 31 located in the living space S. The elastic support member 4 is located in the living space S and connects the upper body support rod 21 and the lower body support rod 31. When in use, the bedridden person lies on the elastic support member 4, and the upper body support rod 21 supports the upper body of the bedridden person, and the lower body support rod 31 supports the lower body of the bedridden person.

The present invention does not limit the type of the base frame 1, and is based on the principle that the first lifting unit 2, the second lifting unit 3 and the elastic supporting member 4 can be stably installed, and the first lifting unit 2, the second lifting unit 3 and the elastic supporting member 4 can be used to safely assist the bedridden person in the accommodation space S to change his/her body posture.

For example, in one embodiment of the present invention, the base 11 may be roughly U-shaped and have a crossbar 111 and two extension rods 112, and the two extension rods 112 are respectively connected to the two ends of the crossbar 111. The two extension rods 112 may be opposite in the X direction; the crossbar 111 and the opening of the base 11 may be opposite in the Y direction, and the crossbar 111 is located at the rear end, and the opening of the base 11 is located at the front end; the stand 12 mainly extends upward from the crossbar 111 along the Z direction, so that the accommodation space S can be formed in front of the stand 12 and above the two extension rods 112, so that the entire base frame 1 can remain stable and not easy to fall when carrying a bedridden person.

In order to improve the mobility of the auxiliary displacement device with various postures, the base frame 1 also includes a moving module 13, which can be arranged at the bottom of the base frame 1, or when the auxiliary displacement device with various postures is to be moved, the moving module 13 is assembled or moved to the bottom of the base frame 1. The present invention does not limit the type of the moving module 13. For example, the moving module 13 can be an application of known technologies such as wheels, tracks, rollers, sliding pads, skateboards or air flotation; in this embodiment, the wheel type is selected for explanation, but it is not limited to this.

In this embodiment, the mobile module 13 can be at least one front wheel 131 and at least one rear wheel 132 disposed on the base 11. In a preferred embodiment, the number of the front wheel 131 and the rear wheel 132 can be two, and the two front wheels 131 can be respectively assembled at the front ends of the two extension rods 112, and the two rear wheels 132 can be respectively assembled at positions adjacent to the two ends of the crossbar 111. The size of the front wheel 131 is smaller than that of the rear wheel 132, and the front wheel 131 can be embedded in the corresponding extension rod 112, so that the front end of the base 11 can be formed thin and convenient to extend under the bed, so that the stand 12 is as close to the bed as possible, so that most of the bed is located in the accommodation space S, so that the bedridden person can be lifted from the bed or carried back to the bed through the first lifting unit 2 and the second lifting unit 3. For example, but not limited to, the front wheel 131 can be a 2-inch wheel, and the rear wheel 132 can be a 10-inch wheel.

In addition, in one embodiment of the present invention, the front wheel 131 can be set to rotate only along a single axis, and the rear wheel 132 can rotate in multiple directions, so that the rear wheel 132 can control the movement direction of the entire multi-position auxiliary displacement device. The rear wheel 132 can also have a self-locking function, so that the entire multi-position auxiliary displacement device can be stopped and fixed at a designated location to prevent unexpected sliding from causing accidents. In some embodiments, the rear wheel 132 can also be electrically controlled to save the caregiver's force in pushing the multi-position auxiliary displacement device, or even directly remotely control the multi-position auxiliary displacement device to move to a designated position.

On the other hand, the upper body support rod 21 and the lower body support rod 31 can be raised and lowered synchronously or independently. In one embodiment of the present invention, the first lifting unit 2 and the second lifting unit 3 can be disposed adjacent to each other on the stand 12, and the upper body support rod 21 and the lower body support rod 31 are disposed approximately in parallel. When holding a bedridden person, the upper body support rod 21 is approximately in the range of important shoulder muscles involved in shoulder joint movement, such as the teres minor muscle, infraspinatus muscle and teres major muscle, that is, approximately in the height of the axilla of the bedridden person. The lower body support rod 31 is generally located at the popliteal fossa of the bedridden person, that is, the concave part behind the knee, also known as the knee fossa. In this way, the upper body support rod 21 and the lower body support rod 31 can jointly maintain a stable hold on the bedridden person, and by changing the height difference between the upper body support rod 21 and the lower body support rod 31, the effect of changing the body posture of the bedridden person is achieved (details will be described later).

The outer layer of the upper body support rod 21 and the lower body support rod 31 may be covered with a soft cushion to improve the comfort of the bedridden person when being held. In addition, the elastic support member 4 may be, for example, an elastic net, so that the elastic support member 4 can fully adapt to the relative height adjustment of the upper body support rod 21 and the lower body support rod 31, and provide a safe and comfortable covering feeling for the bedridden person's trunk, so that the bedridden person can feel safe and relaxed on the elastic support member 4. In addition, the net-shaped elastic support member 4 also helps to improve the comfort and convenience of the bedridden person when defecating or bathing.

Please refer to Figure 3. When the multi-position auxiliary displacement device of this embodiment is used, the upper body support rod 21 and the lower body support rod 31 can be adjusted to almost the same height, and the front end of the base 11 can be extended under the bed, and the stand 12 can be as close to the bedside as possible, so that the upper body support rod 21 and the lower body support rod 31 can support the upper back and back knees of the bedridden person respectively, and then rise synchronously to pick up the bedridden person; then the whole multi-position auxiliary displacement device is moved away from the bedside, and the relative positions of the upper body support rod 21 and the lower body support rod 31 can be adjusted.

When the upper body support rod 21 and the lower body support rod 31 are maintained at almost the same height, or the upper body support rod 21 is slightly higher than the lower body support rod 31, the bedridden person can present a flat embrace posture as shown in FIG3. At this time, the multi-posture auxiliary displacement device can make the bedridden person feel like being held by both hands, and hold the bedridden person to move smoothly and reduce the shaking during the movement; and the body weight of the bedridden person can also be fully supported and the pressure is dispersed by the elastic support member 4 (shown in FIG1), thereby increasing the stability during movement. In addition, the back of the bedridden person can be in a comfortable state with much less pressure than lying on the bed, which makes it easier for the caregiver to massage the bedridden person or assist the bedridden person to do some gentle stretching exercises, etc.

When assisting a bedridden person to defecate, since it is generally easier to defecate in a sitting position, the lower body support rod 31 can be controlled to descend relative to the upper body support rod 21, so that the bedridden person can change to a sitting position as shown in Figure 4, that is, the bedridden person's thighs can be roughly horizontal, so that compared with lying down, defecation can be smoother and more convenient for subsequent cleaning. At the same time, since "being able to sit" is the basis of independent support for defecation, when not defecating, the bedridden person can also be assisted to change to a sitting position, and the bedridden person can be trained to do rehabilitation exercises such as abdominal force, which can help the bedridden person recover or maintain body functions.

When the bedridden person wants to take a bath or wash after going to the toilet, the height difference between the upper body support rod 21 and the lower body support rod 31 can be slightly reduced from the sitting position in FIG. 4 so that the bedridden person's thighs can be tilted upward to change to a bathing position similar to a squatting position as shown in FIG. 5. In this position, the caregiver can bathe, wash, cut hair or do daily grooming for the bedridden person; in addition, this position can also facilitate the caregiver to check whether there are red, swollen or ruptured areas on the body surface of the bedridden person so as to provide timely care. Among them, when the elastic support member 4 is in a mesh shape, the excrement of the bedridden person can easily pass through the elastic support member 4 and be discharged into the toilet, and the cleaning work can be completed more easily and quickly during flushing, which is more comfortable and convenient for the bedridden person and the caregiver.

In addition, before bathing, the whole multi-position auxiliary displacement device can be moved to the bathroom; or in other possible embodiments, the base frame 1 can also be equipped with an ultrasonic spray washing device, and a sewage collection bucket can also be installed on the base 11, or the sewage collection bucket can be placed under the bed when it is to be used, and the present invention is not limited to this.

In summary, the multi-position auxiliary displacement device of this embodiment can assist bedridden people to change various body postures in response to care needs such as lying in bed, bathing or excretion, etc., using a simple structure, which can not only effectively reduce the workload of caregivers and improve work efficiency, but also enable bedridden people to maintain good blood circulation, reduce pressure points and reduce the incidence of bed complications. In addition, the multi-position auxiliary displacement device can also make bedridden people feel safe and comfortable, reduce their struggles or movements, and thus reduce accidental injuries that may be caused during transportation. Therefore, this device not only improves the quality of life of bedridden people, but also ensures the work safety of caregivers, reduces occupational injuries and improves work efficiency. In addition to assisting the movement of bedridden people, this device can also assist bedridden people in simple rehabilitation exercises, and is extremely practical. On the other hand, since the multi-position auxiliary displacement device of this embodiment has a simple structure and can reduce costs and volume, it is very suitable for purchase and use in medical institutions, care institutions or families.

Please refer to Figure 2 again. In an embodiment of the present invention, the first lifting unit 2 may further include a first moving seat 22, which can be driven to move up and down relative to the stand 12, and the upper body support rod 21 can be directly or indirectly connected to the first moving seat 22 to move up and down relative to the stand 12 synchronously with the first moving seat 22. Similarly, the second lifting unit 3 may include a second moving seat 32, which can be driven to move up and down relative to the stand 12, and the lower body support rod 31 can be directly or indirectly connected to the second moving seat 32 to move up and down relative to the stand 12 synchronously with the second moving seat 32.

The components that drive the first moving seat 22 and the second moving seat 32 to generate lifting displacement can be the same or different. For example, a hydraulic cylinder can be used for driving, or a motor can be used with a linear slide rail or a ball screw, or a pulley set and a counterweight block, etc. The present invention is not limited to this; the principle is to be able to control the lifting of the upper body support rod 21 and the lower body support rod 31 respectively, and to be able to stably stop at a predetermined height.

In addition to the above-mentioned embodiments, in one embodiment of the present invention, the upper body support rod 21 and the lower body support rod 31 can be extended and retracted outward, that is, along the X direction to the relative outer sides of the upper body support rod 21 and the lower body support rod 31. In this way, the first lifting unit 2 and the second lifting unit 3 of this embodiment can adjust the relative distance between the upper body support rod 21 and the lower body support rod 31 in the X direction according to the height of different bedridden people, so that the upper body support rod 21 and the lower body support rod 31 can maintain accurate support on the upper back and back knees of each bedridden person.

Wherein, the aforementioned adjustment can be manually or electrically controlled. Please refer to Figures 2 and 6. In an embodiment of electric control, the multi-posture auxiliary displacement device can also include an image capture unit 5 and a microcontroller unit 6 (MCU). The microcontroller unit 6 is electrically connected to the image capture unit 5, and the image capture unit 5 can be mounted on the base 1 or other positions, suitable for the image capture unit 5 to shoot the image of the bedridden person on the elastic support 4 or on the bed toward the accommodation space S; the microcontroller unit 6 can analyze the height of the bedridden person after receiving the image, or identify the bed. The upper back and back knee positions of the bedridden person are detected, and the upper body support rod 21 and/or the lower body support rod 31 are controlled to extend and retract along the X direction to automatically adjust the relative distance between the upper body support rod 21 and the lower body support rod 31 in the X direction, so that the upper body support rod 21 can be roughly aligned with the armpits of the bedridden person, and the lower body support rod 31 can be roughly aligned with the popliteal fossa of the bedridden person.

Furthermore, the first lifting unit 2 may further include a handle 24, which is foldably connected to the first moving seat 22, and the handle 24 is located between the upper body support rod 21 and the lower body support rod 31 in the X direction. Thus, after the upper body support rod 21 and the lower body support rod 31 hold the bedridden person in the accommodation space S together, the handle 24 can be turned out to the accommodation space S for the bedridden person to hold with his hands, so as to enhance the bedridden person's sense of security when maintaining or changing postures, and the handle 24 can be folded toward the stand 12 when not in use.

In addition, in one embodiment of the present invention, a physiological signal measuring unit 241 may be provided on the handle 24. The physiological signal measuring unit 241 may be one or more measuring devices such as heart rate, blood oxygen, blood pressure, blood sugar and/or body temperature. The microcontroller unit 6 is electrically connected to the physiological signal measuring unit 241. In this way, when the bedridden person holds the handle 24, the physiological signal measuring unit 241 may also measure the corresponding physiological signal. The microcontroller unit 6 may receive the measurement result of the physiological signal measuring unit 241, record it or issue a corresponding warning, so that the caregiver can make appropriate corresponding treatment in time.

In one embodiment of the present invention, a weight measuring unit 14 may be provided on the base frame 1, and the microcontroller unit 6 is electrically connected to the weight measuring unit 14. Thus, when the bedridden person is held in the accommodation space S, the weight of the bedridden person may also be measured by the weight measuring unit 14. The microcontroller unit 6 may receive the measurement result of the weight measuring unit 14 for recording, or, for example, issue a corresponding warning when the bedridden person gains or loses too much weight in a short period of time, so that the caregiver can take appropriate corresponding measures in real time.

In one embodiment of the present invention, a battery 15 may be provided on the base frame 1, and the battery 15 may supply the power required for the operation of the microcontroller unit 6, the image capture unit 5, the physiological signal measurement unit 241, and the weight measurement unit 14. In this way, the multi-position auxiliary displacement device of this embodiment has no leakage risk, and is not limited by the power source position, and can be freely moved to any place for operation, with better safety and convenience.

The present invention has been disclosed in the above text with a preferred embodiment, but those familiar with the present technology should understand that the embodiment is only used to describe the present invention and should not be interpreted as limiting the scope of the present invention. It should be noted that all changes and substitutions equivalent to the embodiment should be included in the scope of the present invention.
