SOLUTION: The space saving lift apparatus 1 for converting a body posture, has simple constitution not adapted to the postural conversion of the whole of the body of a patient and specified in order to convert the body posture for the purpose of evacuating the bowels or preventing a bedsore. The auxiliary instruments 40 and 45 for evacuating the bowels or preventing a bedsore and the auxiliary instrument for turning over in bed are used in the hook part 30 of the lift apparatus 1. Since only a part of the body of the patient may be lifted, the lift apparatus can be simplified in constitution and is inexpensive and can conserve a space. Therefore, the lift apparatus can be arranged in an ordinary home or a large room of a hospital. The patient can convert his body posture himself in a state attached to the auxiliary instruments.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention facilitates the change of body position for preventing defecation or decubitus (bed sores) or turning over for a patient who has become so-called "bedridden" due to paralysis of his limb due to an accident or illness. The present invention relates to a body-position changing lift device used for lifting and an auxiliary tool mounted on a hook of the body-position changing lift device.

[0002]

2. Description of the Related Art It is impossible or impossible for a patient who has become paralyzed due to an accident or illness to have a so-called "bedridden" state to perform a daily operation such as defecation or turning over. However, there are many difficulties, and a pressure ulcer (bed sores) resulting from a place where the same part of the body is pressed against the bed for a long time is a serious problem.

For example, during defecation of a patient having paralysis in the lower body, two caregivers insert their necks below the knees of the right and left legs R and L of the patient on a bed B as shown in FIG. 8a. And lift it up, and insert a portable toilet U into the crotch of the patient to take a stool. This operation cannot be performed by a single caregiver alone, and may be performed by three unskilled caregivers.

When stool collection is performed by the above-described method, the patient's legs are often not fully lifted. In such a case, the simple toilet U is forced into the crotch. The buttocks of the patient may be rubbed at the rim of the U and, in severe cases, may result in bleeding.

[0005] Alternatively, in the case of a so-called "bedridden" patient with paralysis of the limbs, prevention of pressure ulcers is a major problem as described above, but changing the body position to prevent this, that is, turning over, raising and lowering the feet, etc. The caregiver had to be troubled, which was a major problem for both the patient and the caregiver.

[0006]

In order to solve the above problems, a number of lifting devices for lifting a patient's body have been developed. Some examples are shown in FIGS.
c. The lifting device of FIG. 12a is mobile, with legs 60c, 60c inserted under a bed (not shown) and an arm 60c.
A, an auxiliary tool (not shown) is hooked on hooks 60b, 60b fixed to the tips of the a, 60a, and the arms 60a, 60a are lifted to support the body of the patient (not shown) supported by the auxiliary tool (not shown). (Not shown).

Alternatively, the lift device shown in FIG. 12B is a fixed type, in which legs 61c, 61c are developed and fixed on the floor of the pillow head of the bed B, and hooks 61 fixed to the tips of the arms 61a, 61a.
b, 61b, an auxiliary tool (not shown) is hung on the arm 61a,
By raising 61a, the patient's body (not shown) supported by the assisting device (not shown) is lifted.

[0008] The lift device shown in Fig. 12c is also of a fixed type.
c, 62c are vertically suspended, a guide rail 62d is provided at the upper end of the columns 62c, 62c, and arms 62a, 62a capable of moving horizontally and vertically are suspended from the guide rail 62d.
Auxiliary equipment (not shown) is hooked on hooks 62b, 62b fixed to the tip of 62a, and a patient's body (not shown) supported by the auxiliary equipment (not shown) by raising arms 62a, 62a. )).

The above-mentioned lifting devices 60, 61, 62 can also be used for changing the position of a patient. However, the above-mentioned lift devices 60, 61, 62 are essentially all designed and manufactured with a focus on the transport of the patient, and the patient's entire body is lifted from the bed and transferred to a wheelchair or the like. The overall configuration is made for the main purpose.

[0010] Therefore, it is inevitable to have a structural strength capable of holding the entire weight of the patient, and it is necessary to make each member robust enough to necessarily hold the total weight of the patient. Occurs, and the overall configuration becomes large-scale. In particular,
The legs that support the entire device must have a robust structure that can withstand and move the entire weight of the patient, and the legs must have a long distance between fulcrums that contact the floor to ensure stability. .

Specifically, the lifting device 62 of FIG.
Is a scale that occupies substantially the entire room in which the bed B is placed. The lift device 60 in FIG. 12A and the lift device 61 in FIG.
At first glance, it looks compact, but it occupies a surprisingly large area, which is too large to accommodate in a typical home, even for a room of 8 tatami mats. Further, the pressure applied to the portion in contact with the floor surface is large, and damage to the floor is inevitable.

However, what is more troublesome than that is the fact that it is practically impossible to place all of the lift devices 60, 61 and 62 in a hospital. As is well known, hospitals in Japan mainly use a so-called "large room" with a plurality of beds in a single room, and the occupied area of each bed including the periphery is extremely small. Thus, even the most compact lifting device 60 of FIG. 12a cannot be placed.

Also, in the case of a private room, in a Japanese hospital, a private room with a size of more than 8 tatami mats in a normal home is extremely rare.
None of 60, 61 and 62 can be installed.

As described above, under the current medical situation in Japan, it is almost impossible to place the lift devices 60, 61, and 62 in a hospital. It is normal for caregivers to do it manually, as in. For this reason, momentum caregivers are given priority, and patients often do not receive sufficient care.

The assisting device to be hung on the lift devices 60, 61, 62 is also manufactured on the premise that it can support the entire weight of the patient, and is used for collecting blood on a bed or turning over. For the purpose of lifting part of the patient's body, it is unnecessarily durable and large-sized, making it difficult to use, and it is expensive, and the financial burden on the patient and caregiver cannot be increased Did not get.

[0016] Alternatively, it is most preferable to change the body position when turning over, etc., whenever necessary according to the patient's own intention. However, the assisting devices hung on the lift devices 60, 61, 62 mainly transfer the patient. Because of the purpose, the wearing method is also large, it is not possible to take a sleep posture while wearing it, the patient is always wearing it, and it is not possible to change the body position by operating the remote controller by himself whenever necessary. It has a possible configuration.

[0017] The present invention eliminates the above-mentioned current situation. To develop and provide a compact and inexpensive lift device exclusively for posture change that lifts only a part of the body, not the whole body of the patient. . To develop and provide an inexpensive auxiliary tool with a simple configuration dedicated to postural change to be attached to the lift device. . The above-mentioned assistive device shall be ready for sleeping while being worn, and shall be operable at any time by the remote controller according to the patient's will. The above three points have been set as subjects of the present invention.

Next, the body-position changing lift device 1 (FIG. 2)
Among the assisting devices of the present invention that are hooked on the hooks 38 and 39 of the hook portion 30 of (a), the configuration of the turning assisting device 50 will be described in detail. 9 is an external perspective view of the auxiliary tool 50, FIG. 10a is a front view of a main part of the auxiliary tool 50, and FIG.

As shown in FIGS. 9, 10a and 10b, the auxiliary tool 50 is a substantially rectangular sheet made of a flexible material such as cloth, leather, or soft synthetic resin between synthetic resin pipes 51 and 52. Department
59 so that the short side is located at both the left and right ends, and
The left end of 59 is connected to the pipe 51, and the right end is connected to the pipe 52, and is mounted between the pipes 51 and 52.

In this embodiment, a metal reinforcing pipe 53 having the same length as the pipe 51 is provided inside the pipe 51, and a metal reinforcing pipe 53 having the same length as the pipe 52 is provided inside the pipe 52. Reinforcement pipes 54 are closely fitted and fixed. Reinforcement pipe 53, 54
Is for reinforcement to supplement the strength of the pipes 51 and 52, and is not always necessary when a material having sufficient strength is used for the pipes 51 and 52.

The seat portion 59 is made of cloth in this embodiment. The left end of the seat portion 59 is wound on the pipe 51 and the right end of the seat portion 59 is wound on the pipe 52, and sewn to itself at the sewing portions H, H. Therefore, the left end is in the outer pipe 51 and the right end is in the outer pipe 52 in a loosely fitted state. In this embodiment, since the sheet portion 59 is made of cloth, a means called sewing is used, but it is also possible to use an adhesive instead of sewing. If leather is used as the material of the sheet portion 59, sewing or adhesion may be used, and if soft synthetic resin is used, adhesion or welding may be used.

As shown in FIG. 9, the reinforcing pipe 53 has a rope 55 having a length about three times the reinforcing pipe 53, and the reinforcing pipe 54 has a rope 56 having a length about three times the reinforcing pipe 54. Each has been inserted. Both ends of the rope 55 are loops 55a and 55b, and both ends of the rope 56 are loops 56a and 56b.
Reference numerals 57a, 57b, 58a, and 58b denote ring-shaped stoppers which are externally fitted to the bases of the loops 55a, 55b, 56a, 56b in order to maintain the shape of the loop.

Next, the operation of the present invention will be described in detail with reference to the drawings. The operation when the assisting devices 44 and 45 of the present invention are hooked on the body-position changing lift device 1 of the present invention is as follows. First, as shown in FIGS. 7a and 7b,
The patient 40 is wound from above the knee of the right leg R of the patient to the thigh so that the upper surface of the support plate 41 abuts from the back of the patient's right knee to the back of the thigh.

At this time, care should be taken not to overtighten, and the three es hooks S, S, S are hooked and fixed on appropriate meshes. At this time, the right knee is raised in FIG. 7A, but the winding is possible even when the right leg is in a substantially horizontal state. Although not shown, the auxiliary tool 45 shown in FIG. 6C is similarly wound around and fixed from above the knee of the left leg to the thigh.

Next, as shown in FIG. 1A, the sliding portion 7 is slid along the guide rail 6a of the body-position changing lift device 1 so that the driving portion 10 is placed almost directly above both knees of the patient. And the arms 36 and 37 of the hook portion 30 are positioned parallel to the short side direction of the bed.

Next, the patient's both knees are set up, and the loop 44 d of the hook 44 of the assisting tool 40 is attached to the hook 38 of the arm 36.
The loop 49d of the hooking portion 49 of the assisting tool 45 is hooked on the hook 39 of the arm 37, respectively. This completes the winding of the assisting tools 40 and 45 around both feet of the patient and the hanging of the assisting tools 40 and 45 on the body-position changing lift device 1. FIG. 1a shows this state.

Next, the steel cable 31 is raised (in the direction of arrow α) or lowered (in the direction of arrow β) by operating the remote controller 8. As a result, the hook portion 30 is also raised or lowered, and the right leg R of the patient is
The left leg L also rises or falls around the knee. When the hook portion 30 is raised higher than the state shown in FIG. 1A, the hook portion 30 can be lifted and released from a state in which it comes into contact with the upper surface of the bed B from the buttocks of the patient to the middle of the back.

In the case of a so-called bedridden patient, pressure ulcers are most likely to occur from the shoulders to the buttocks, where the weight is strong. It can also prevent back pain. Auxiliary tools 40, 45, right leg R, left leg L
The caregiver must take care of the caregiver's hand to wrap around the body and hang the lift device 1 on the lift 30. However, since the sleeping posture can be taken even when the body is wound, the fingertips of the hand move. By operating the remote controller 8 at any time, the patient can adjust the elevation by himself / herself to prevent the occurrence of pressure sores and back pain from around the buttocks to the middle of the back.

By raising the hook portion 30 high during defecation, the height from the buttocks to the back is raised as shown in FIG. 8B. In such a state, the stool collection operation can be performed extremely easily only by one caregiver inserting the simple toilet U into the crotch of the patient. Moreover, since the buttocks can be raised much higher than the case where the caregiver manually lifts both legs of the patient as shown in FIG. 8A, the situation where the buttocks are rubbed by the ends of the simple toilet U can be prevented.

The raising and lowering of the hook portion 30 (see FIG. 1A) may be performed by the caregiver. In the case of a patient who can move the fingertip, the patient operates the remote controller 8 while communicating with the caregiver. There is an advantage that the patient can avoid being in an unreasonable posture when performing the treatment.

Next, the operation when the assisting device 50 of the present invention is mounted on the body-position changing lift device 1 of the present invention will be described. First, the seat portion 59 of the assisting device 50 in FIG. 9 is laid under an arbitrary portion from the shoulder to the waist of the patient. At this time, the left end of the seat portion 59 loosely fitted to the pipe 51 is positioned on the left side of the patient's body.
The right end of the seat portion 59 loosely fitted to the 52 is positioned on the right side of the patient's body.

Next, as shown in FIG. 2A, the sliding portion 7 is slid along the guide rail 6a of the body-position changing lift device 1, and the driving portion 10 is placed on the seat portion 59 of the assisting device 50. The arm 36, 37 of the hook 30 is positioned parallel to the longitudinal direction of the bed.

Next, the patient's body is turned to the right (turning over).
If it is desired that the loop 55a of the rope 55 inserted through the reinforcing pipe 53 be hooked to the hook portion 30 as shown in FIG.
38 and the loop 55b are hooked on the hook 39, respectively. In this state, if the hook portion 30 is raised (in the direction of arrow α), the torso of the patient will rotate (turn over) to the right (in the direction of arrow γ). Conversely, if the hook portion 30 is lowered (in the direction of the arrow β), the patient's torso rotates (turns over) to the left (in the direction of the arrow δ). In this case, the right end of the seat portion 59 is free to move, but the seat portion 59 below the body D can be moved to the bed B by the weight of the patient.
So it does not move.

Next, the patient's body is rotated to the left (turning over).
If it is desired, the loop 56a of the rope 56 inserted into the reinforcing pipe 54 is hooked on the hook portion 30 as shown in FIG.
38 and the loop 56b are hooked on the hook 39, respectively. In this state, if the hook unit 30 is raised (in the direction of arrow α), the patient's torso rotates (turns over) to the left (in the direction of arrow δ). Conversely, if the hook portion 30 is lowered (in the direction of arrow β), the patient's torso rotates (turns over) to the right (in the direction of arrow γ). In this case, the left end of the seat portion 59 can move freely, but the seat portion 59 below the body D can be moved to the bed B depending on the weight of the patient.
So it does not move.

FIG. 2A shows a state where the patient himself is turning over by operating the remote controller 8. In the case of the assisting device 50, since the thin-film sheet portion 59 is merely laid under the body, when the patient takes a normal sleeping posture, the patient himself has almost no discomfort, and it is always laid. If you want to turn over at any time, you can operate the remote controller 8 to get the body D
Can be turned (turned over).

Although the assisting device 50 has been often described as "for turning over", it is said that turning over is a natural posture change during bedtime and also has an effect of preventing pressure ulcers. Not even. Therefore, although it is not specifically described as “for preventing pressure ulcers”, it cannot be overemphasized that the auxiliary tool 50 is also used for pressure ulcer prevention.

The lift device for changing body position according to the present invention is not intended to lift the entire body of a patient, and is a device specialized for changing body position. Therefore, only a part of the body of the patient is lifted. Any configuration is possible. Therefore, it can be configured much more compactly than the conventional lift device, and each member does not need to be as rugged as the members of the conventional lift device, the mechanism is simple, there are few failures, the production cost is much cheaper, The economic burden on hospitals, patients and caregivers is reduced.

In particular, regarding the occupied space, the repositioning lift device of the present invention can be configured with a much smaller leg portion than the conventional lift device, and can be placed close to and parallel to the short side of the bed. It can be installed if there is a space where a leg shorter than the short side can be installed. Therefore, it can be installed in each bed of a large room of a hospital as well as a private room of a general home or a hospital.

Further, in the body-position changing lift device of the present invention, since the support column is provided upright on the short side of the bed, not only the patient himself / herself goes up and down on the bed, but also various medical work performed by a doctor or a caregiver. Nothing in the way. In a large hospital room, a curtain that separates an adjacent bed is usually provided along the longitudinal direction of each bed, but this does not interfere with the curtain.

Further, the assisting device for defecation and pressure ulcer prevention of the present invention, which is hung on the above-mentioned body-position changing lift device, is not as complicated as the conventional assisting device, and has a very simple structure with the knees of both legs of the patient. Because it is specialized only to lift the upper thighs, it is easy to wear (wrap), it can be put to sleep even while wearing it, and if the patient's fingertips move, the remote controller can use Can lift the knee,
Further, since it can be lifted from the buttocks to the middle of the back, it is effective not only for prevention of pressure sores from the legs but also for prevention of pressure sores from around the buttocks to the middle of the back and low back pain. It is also useful for rehabilitation.

Further, by using this auxiliary tool to raise the patient's buttocks and back high, it is possible for one caregiver to insert a simple toilet bowl into the patient's crotch when defecation is performed. However, the burden on the caregiver is extremely light. As you can raise your hips higher,
The patient's hips are no longer abraded at the end of the toilet. In addition, the patient whose fingertip moves can be operated by himself / herself by using the remote controller, so that the patient is not forced to take an unreasonable posture.

Further, since the auxiliary tool is configured to hang the es hook on the mesh of the net and wind it around the thigh above the knee, the es hook may be hooked on an arbitrary mesh to make the thigh of the patient thigh. It is possible to wind it with an appropriate degree of tightening according to the size of the part. Furthermore, a plurality of eshoots are hooked along the short direction of the net, and these eshoots can be hooked to an arbitrary mesh, so that the shape of the thigh varies slightly depending on the individual patient. It is possible to wrap it faithfully.

Further, the turn-over assisting device of the present invention, which is hung on the above-mentioned body-position changing lift device, has a very simple structure, and a sheet portion made of a thin film is usually laid under the patient's body. Therefore, it can be laid at all times without any discomfort for the patient, and can be used when it is necessary to turn over at any time. Therefore, it is possible to avoid a situation in which a caregiver is woken up for a change of position at night.

Further, since the turning aid of the present invention can rotate the torso portion of the patient by a desired angle, the posture change can be performed very efficiently, and can be laid on any part from the shoulder to the waist. Therefore, it not only has a great effect in preventing pressure ulcers from the shoulders to the waist, but also is useful in preventing back pain and rehabilitation. Furthermore, since the configuration is simple, the production cost is low, and the burden on patients and caregivers is low.

Further, in the turnover aid of the present invention, it is possible to easily replace the sheet part, which is considered to be the fastest deterioration among the members, so that it can always be used in the best condition, and economic efficiency can be improved. Is also excellent. The seat portion can be manufactured by sewing a normal bath towel, and can be easily removed and washed.

Lastly, the basic posture of the present invention from a comprehensive viewpoint and the effects of the basic posture will be described. First, while the conventional lift device and assistive device were mainly configured from the viewpoint of the caregiver and mainly for the convenience of care, the lift device for changing the position of the present invention, the defecation and pressure ulcer prevention The assisting device for turning over and the assisting device for turning over have been developed with an emphasis on convenience and comfort from the viewpoint of the patient receiving care.

Therefore, regarding the conversion of the body position, it is considered necessary to respect the patient's will as much as possible and to adopt a configuration in which the patient can change the body position as desired when desired. Therefore, it is not difficult to always wear the device as in the conventional assistive device, and it is not impossible to always wear it. The basis for development.

Therefore, the present invention is based on the basic concept of development of switching the viewpoint from the "caregiver side" to the "caregiver side".
With the idea that respect for the independence of the patient will be reduced, the burden on the "caregiver" will be reduced.

Another point to be noted in the development is that, instead of special people with economic grace, to develop realistic lifting devices and assistive devices that can be used by ordinary people. It is. In other words, expensive equipment that requires a large space, such as a conventional lift device and an auxiliary tool, can be used only by a limited number of people, no matter how good its performance is.

On the other hand, by providing an extremely inexpensive lift device and assisting device having a small space and a simple structure in accordance with the current state of Japanese residences and hospitals, the present situation of Japan in an aging society is realized. The main object of the present invention is to be able to cope with the problem. Therefore, we believe that it has not only the direct effect described above, but also an effect that brings a new dimension to the way of thinking about care in Japan.
