Description

   The present invention relates to a bed for storing and rotating a human body.

When observing the sleeping phase of a healthy person, the body is periodically in a supine (upward), lying down (sideways), prone (downward) state, or bent and stretched. In the case of a care recipient, since part or all of the above-mentioned movements cannot be performed by himself, the body position is left in the same position for a long time, causing congestion and necrosis. Also, I feel very painful without causing congestion or necrosis. The caregiver often helps and takes care of the above movements (busyness), but this is not enough. In addition, the caregiver needs to hold, lift, and flip (e.g., bad posture, heavy labor) when performing care, causing the caregiver to have back pain and numbness in the limbs. The care recipient needs to change his mind to make it easier for food to fall into the stomach at mealtime and to stand for rehabilitation. Therefore, caregivers are forced to have a lot of labor (heavy work) and patience (nuisance) for a long time, and caregivers are full of caregiver's labor and patience (annoyance), and it is cold in winter The summer is hot and the inside is muggy and uncomfortable (comfort). The care recipient is just bored (entertainment) just by sleeping

As a preventive measure, the floor parts automatically move up and down alternately to change the contact and support part of the human body, shake the entire bed 90 degrees to the left and right, and raise a part of the bed for easy care. Or published.
Real Open 06-005786

However, they improve and satisfy only a part of busyness, bad attitude, heavy labor, annoyance, discomfort and boredom.

The problem to be solved is that the caregiver is forced to have busyness, bad posture, heavy labor, annoyance, and the care recipient needs annoyance, discomfort, and boredom (anti-entertainment).

In the present invention, openable / closable open / close frame portions are attached to both surfaces of the rotary frame, and a thick pipe for dispersing body pressure is attached to support and fix the body in each open / close frame portion, and the rotary frame is rotated. The rotating frame itself is raised. Caregivers can take care of and care with a light effort by stopping the rotating frame at any desired position (improving bad posture, heavy labor, and annoyingness). Install audio, visual equipment, or communication equipment such as the Internet or telephone (improvement of boredom). In some cases, a simple air conditioner will also be installed (comfort).
The electric circuit is assembled in a desired operation and cycle suitable for each care recipient, and the operation to automatically put the rotating frame into the supine, lying down, prone state is performed (improvement of busyness and annoyingness).

The care recipient can prevent congestion and necrosis in the present invention. Energy saving and comfortable environment can be obtained. Be connected with the outside and not isolated. Only a minimal burden on the caregiver. It can be done at 360 degrees instead of 180 degrees and blood circulation is improved. The body does not move on its own, so it doesn't drain, and it can bend and stretch to some extent by the gap between the pipes. If you place a hot water tray on the floor, you can wash the body of the care recipient with a shower. Caregivers can take care with an easy posture and light labor, and only receive a minimum burden from the care recipient.
The product of the present invention is comfortable and can be used for healthy people.

  In order to reduce the number of times of nursing care, easy posture, light labor, and entertainment, it was realized with a simple structure, inexpensive parts, a minimum number of parts, simple installation and operation.

  This apparatus comprises a container part for storing a human body, a support part for supporting the container, a drive part for moving the support part, a control part for operating the drive part, and a safety device part. The material of the container part and the support part should be light, strong and strong. Wood, metal such as aluminum and synthetic resin. When using a shower, it should be waterproof.

FIG. 1 is an external perspective view of the apparatus in which a caregiver manually rotates a container. The container part is a rotating frame 1 having both surfaces opened, an upper opening / closing frame 2 having both surfaces opened, and a lower surface. It consists of a lower opening / closing frame 3 that is installed and open on both sides. The rotating frame 1 may be one in which only one of the upper surfaces is opened. The rotation / opening / closing frame has a shape and size that can accommodate a human body. For example, it is about 45 cm in total of 65 cm in width x 185 cm in depth x 3 frames in height. Punch boards with a number of through-holes are stretched inside the upper and lower open / close frames so that they protrude from the height of the upper and lower open / close frames and the position of the pipe or pipe-shaped body can be adjusted to the height of the sleeping body. ing. The entire upper and lower open / close frames may be formed of a punch board. Using the through holes, the pipes 4a and 4b that prevent the human body from moving up and down are connected and fixed to the positions of the upper and lower opening / closing frames that match the body shape. A pipe 4c for preventing movement of the human body in the horizontal or vertical direction is connected and fixed to the pipe 4a or 4b.

The rotating frame 1 is fixed to a large wheel 5 that tilts the container portion with connecting bodies 6a and 6b or 8 at the center. The size of the wheel 5 is such a size that the container part can be rotated and cared for. For example, the diameter is 90 cm. In order to keep the wheel 5 in that position, the wheel 5 is placed on two smaller spinning wheels 5a and 5b. Since it is supported at two points on one side, it is very stable, and even if the wheel 5 is turned by hand and released, the container part keeps an arbitrary angle (a supine, lying down, prone) even if the center of gravity of the container is slightly deviated. Hinge 7a and 7b are connected so that the rotating frame and the upper and lower open / close frames can be opened and closed for easy care. It is desirable that the hinge can be separated into two by removing the mandrel so that the upper and lower opening / closing frames can be completely separated from the rotating frame.

Caregivers periodically rotate containers. In addition, if it is desired to care for the abdomen of the person requiring care, the container is turned to the supine state, and the opening / closing frame 2 is opened as it is from the gap between the pipes. It is even easier to remove the entire upper open / close frame 2. If you want to care for the back, you can turn the container to the prone state and leave it open or remove the lower opening / closing frame 3 or remove the holding body 4c. It can be done at any container angle and posture that caregivers can easily do.
Caregivers can lie down and sleep in a comfortable position.

FIG. 2 shows one point support on one side. The container shaft 8 is held by the column 5c instead of the wheel 5. Although it is unstable compared to FIG. 1, it can rotate with a slight force if the center of gravity is matched.
A weight may be attached to an arbitrary position of the container so that the center of gravity of the container is aligned with the axis 8.

FIG. 3 shows the positional relationship between the human body, the rotating frame, the upper and lower opening / closing frames, and the pipe.
The pipe 4b that supports the back side of the body, the pipe 4a that supports the abdomen when inverted, are arranged as shown in the figure, for example, as shown in the figure, so as to disperse the body pressure. Fix and sandwich your body in a sandwich. When the rotary frame 1 is tilted, the lateral parts of the body are supported by laterally shifted pipes 4c fixed to the pipes 4a or 4b so that the body does not shift horizontally or vertically. For example, the head, neck, armpit, arm, waist, and both sides of the foot. The foot is also supported in the middle of both feet. If you put your shoulders between your neck and armpits, your body will not shift horizontally or vertically.

FIG. 4 shows a method for connecting and fixing the pipes 4a, 4b and the pipe 4c between the pipes 4a, 4b and the frames 2, 3 for supporting the body. With the opening of the C-type channel 13 facing upward, the fixing block 10 having two screw holes at the ends is inserted, and the C-type channel 13 is tightened with the screws 12 with the presser plate 11 and fixed. Two screws 12a and 12b are inserted into the through holes 9a of the punch board 9, and the punch board 9 and the block 10 are firmly fixed so that the C-shaped channel 13 does not loosen or rotate. The C-type channel 13 is covered with a hard pad and pad 19 so that the body does not hurt and is not painful to form pipes 4a and 4b. The cross section of the pad 19 may be circular.
A long bolt 14 is inserted into an elongated pipe 16 having a notch 17 which is inserted into the opening of the channel 13 at the lower part to prevent rotation, and is turned and fixed with the channel plate 13 sandwiched between them. The head 18 of the bolt 14 is fixed to the pipe 16 with a screw so that the bolt 14 does not loosen. The position of the pipe 16 can be adjusted continuously and continuously. The pipe 16 is covered with a pad 19 to form a pipe 4c. Alternatively, the channel 13 may be turned over to provide a plurality of through-holes 20 that are threaded on the bottom surface, and a rotation-preventing projection 21 may be provided at the bottom of the elongated pipe 16 and inserted into the through-hole 20. The position of the pipe 16 can be adjusted step by step.
A dedicated bar-shaped support 22 may be used or provided.

FIG. 5 shows a case where a harder and larger padding body and a pad 23 are installed in accordance with the shape of the head, back, buttocks and legs. In general, a portion of the container rotation cycle that takes a large proportion of time, for example, a supine portion, is held in a particularly easy state. A lid 24 that can be opened and closed or attached to and removed from the buttocks portion of the pad 23 is provided so that the lower care can be easily taken. A hole through which the pipe 4c can penetrate is made in the abutting body 23, and adhesive tapes 25a, 25b and the like are attached and fixed to the abutting body 23 and the channel 13. Alternatively, they may be fixed by tying them with a string or the like. Can be removed and washed.
A tape 26 may be passed between the pipes 4c to prevent lateral displacement.

FIG. 6 shows the upper opening / closing frame 2 with an air-conditioning lid 27 for keeping warm and cold. Fasten with screws so that it can be removed. One large or a plurality of small through holes 28a are provided in the face portion so that breathing is possible, and one large or a plurality of small through holes 28b are provided in the foot portion. An exhaust fan may be installed in the through hole 28b. Moreover, you may install a deodorizer in an exhaust fan. An air conditioning lid is also attached to the lower opening / closing frame 3. You may provide a through-hole also in a lower air-conditioning lid. The air-conditioning lid 27 is preferably made of a lightweight and heat insulating material. For example, synthetic resin.

Since it is uneasy that the opening / closing frame 2 cannot be opened from inside the container, it should be opened. A long T-shaped rod 29 is inserted into the through holes of the metal fittings 30a and 30b with through holes fixed to the rotary frame 1. The tip of the rod 29 is inserted into the through-hole of the metal fitting 33 installed and fixed to the opening / closing frame 2 by the force of the compression spring 31 sandwiched between the metal fitting 30a and the stopper 32 installed on the rod 29, and the opening / closing frame 2 and the rotating frame 1 is locked. Another T-shaped bar is placed symmetrically on the lower side. If one of the T-shaped short parts is put into the container and the other is put out of the container, and one pair of the parts is gripped, the tip of the rod 29 is retracted from the through hole of the metal fitting 33 and the opening / closing frame 2 is pulled out from the container Can be opened. If you hold the other pair of parts, you can open it from the outside. Further, the guide rod 34 fixed to the rotating frame 1 may be installed in the middle and middle of a pair of parts so that the three guide bars 34 are gripped together so that they do not shift to one side when gripped. If the T-shaped long rod 29, guide rod 34, metal fittings 30a, 30b are installed in the opening / closing frame 2, and the metal fitting 33 is installed on the rotating frame 1, the lock can be released with one hand and the opening / closing frame 2 can be opened as it is. The T-shaped bar 29 may be installed on either the left or right side of the frame 1 or 2.

FIG. 7 shows the container standing up. The display of the upper and lower open / close frames is omitted. Another rotating frame 1a is provided outside the rotating frame 1, the shaft 37 fixed to the rotating frame 1 is inserted and held in the through hole of the rotating frame 1, and the gear 35a is fixed first. The gear 35b held on the rotary frame 1a is turned by the handle 36, and the gear 35a larger than the gear 35b is turned to raise the container. At this time, the locking device 38 is put on the wheel 5 so that the container does not rotate. If the handle is locked at a desired angle, the state is maintained. If you want to apply a larger force, use one with a large gear ratio. For example, a worm gear. When the container is stored, the rotating frame 1 and the rotating frame 1a are fixed by a metal fitting 39 fixed to the rotating frame 1 so that the container does not rattle. L1 is a length that does not hit the wheel 5 so that the upper opening / closing frame can be opened.
You may attach the wheel 40 for a movement and evacuation to a floor grounding part. The wheels 5 may be sandwiched between the wheels 5c so that the wheels 5 are not detached from the wheels 5b.

FIG. 8 automatically rotates the container using the driving source. An elliptical gear 41a is installed on the shaft 8 which is fixed to the container and rotates the container, and an elliptical gear 41b is installed on the pair, and is rotated by a drive source. Switches 43 a, 43 b, 43 c, 43 d for detecting the rotation angle of the container are installed at desired angular positions around the shaft 8, and the switches are operated by the projecting pieces 44 installed on the shaft 8. You may increase / decrease the number of the switches 43 which detect the rotation angle of a container according to a desired angle. In order to prevent the shaft 8 and the container from turning too far, an overclocking prevention switch 45a, an overclocking prevention switch 45b, and an emergency overturn prevention switch 45c are installed above the shaft 8. One end of a string 46 having a length (a length within a permissible range for twisting and winding described later) with respect to a desired rotation angle (however, power supply, communication, control cable 47 to be described later, within a permissible winding range) is connected to the switch operating piece. The other is connected and fixed to the shaft 8. The length of the string 45c is longer than that of 45a and 45b. When the shaft 8 rotates, the string 46 is wound around the shaft 8, shortens, and pulls the operating pieces of the switches 45a, 45b, 45c. The operating piece of the emergency over-rotation prevention switch 45c is preferably attached and detached.

The hollow shaft 8 is convenient because it can accommodate the power supply, communication, and control cables 47 of the air conditioner, lighting equipment, audio equipment, visual equipment, etc. used in the container, or communication equipment such as the Internet and telephone. Since electricity is supplied to the container, which is a rotating body, using the twist of the cable, no electrical contact is required. Alternatively, the cable winding wheel 48 may be used for winding and returning.
The reason why the elliptical gear is used instead of the circular gear is that the speed at the start and end of rotation can be slowed even with an inexpensive and robust constant speed rotational drive source. It is comfortable for the care recipient and tends to stop the container at the desired position angle. If the minimum angle is 90 degrees, an elliptical 4-lobe gear is used. If it is 180 degrees, an elliptical 2-lobe gear is used. An elliptical n-leaf gear is selected according to the minimum angle obtained by dividing 360 degrees into n. The angle change ratio may be changed by changing the eccentricity. The change in the container rotation speed may change the rotation speed of the rotation drive source.
Of course, only circular gears may be used.

FIG. 9 shows an electric circuit of the operation control and safety device of the drive source of FIG. 8 as an example. Four switches 43a, 43b, 43c, and 43d that detect the rotation angle equally arranged with the elliptical four-leaf gear are used, and the container minimum rotation angle is set to 90 degrees. Supine movement, right rotation, prone movement, right rotation, left recumbent movement, left rotation, right recumbent movement, left rotation, supine movement, left rotation, prone movement, left rotation, right recumbent movement, right rotation, left recumbent movement, right The rotation and supine movement are automatically repeated as one cycle. It is better that the right rotation number, angle and left rotation number, and angle of the container are the same during one cycle. Conveniently balanced human body and cable twist.

Electricity from the plug is an emergency stop switch S1, an operation switch S2, a container lid opening / closing switch S3 (installed on the metal fitting 33 and senses that the tip of the rod 29 has been inserted into the through hole of the metal fitting 33, or a rotating frame and an opening / closing frame. The switch enters a timer T1 via a function selection rotary switch S4, a safety switch S5, and a supine forced setting contact s6. After t1 seconds, the contacts S7 and S8 are closed and the drive circuit is closed, electricity flows into the motor R terminal, and the motor M1 of the drive source 42 is rotated to the right (if the connection cable 49b is connected to the L terminal, for example, the motor M1 is rotated to the left). Can be set arbitrarily.) The timing contacts R1, R11, and R12 are used so that the motor can be turned after the brake B that brakes the rotation of the motor is released and the brake B is turned on after the motor current is turned off. Brake B has a structure that can be released manually in the event of a power failure. The motor and the container rotate, and at the same time, the projecting piece 44 also rotates 180 degrees to operate the switch 43c (if the connection cable 49a is connected to, for example, the 43d terminal, the motor can be arbitrarily set to rotate 270 degrees). When the switch 43c is operated, its contact a closes s9 and is held by the relay R1. Self-holding is continued as long as the timer T1 is not reset. At the same time, the b contact s10 of the relay R1 is opened to stop the current flowing into the R terminal, the a contact s11 of the relay R1 is closed, and the next timer T2 is operated. The following is repeated until the timer 8 is reached, but the b contact s12 is opened and reset for a moment by the operation of the relay R8. The same cycle is repeated thereafter. In the unlikely event that the container rotates too much, first, the b contacts S13 and S14 of the over-rotation preventing switch 45a or 45b are opened to stop the rotation of the motor. If it still does not stop, the operation piece of the emergency rotation preventing switch 45c comes off and is securely stopped. When the time interval for moving to the next operation is long, it is not known whether the device is stopped, so the operation check lamp L is installed. The interval to move to the next operation is arbitrarily adjusted with a timer.
A desired cycle can be set by simply connecting with the connection cables 49a and 49b or changing the timer period. For safety, it does not operate when the lid is open, and stops when the lid is opened (S3 is open). During operation, it stops when a person approaches (S5 is open).

The caregiver can manually rotate and stand the container to any position, and can easily and safely care for it.
The function selection rotary switch S4 is switched to 3, and electricity is supplied to the left L or right R rotation terminal by the push button switch S15. The switch S15 is preferably provided with an extension cord. Can be operated at hand.

When the container is raised, the rotary switch S4 is switched to 4, and the circuit of the rotary switch S4 and the rotary switch S4 are divided by the contact of the relay R12 in order to share the switch S15. Turn the standing motor M2 set to 35b. The standing motor M2 is a switch L3 for confirming the disengagement between the frame fixing bracket 39 and the rotating frame 1a (actuated by removing the screw at the back of the screw hole), a switch L4 for the lock device 38, and a confirmation limit switch for container storage. Since either L1 or the limit switch L2 for confirming the maximum container standing angle (the projecting piece set on the shaft 37 is operated by pressing the switches L1 and L2) does not move, it is safe.

A conscious care recipient can control the movement by himself.
If function selection rotary switch S4 is switched to 1 and switch S16 in a container is pushed, rotation of a container will stop in that position. If you want to stop or feel sick, press switch S17 to activate relay R13, forcibly bring the container to the supine position until the contact b of switch 43a and relay R19 opens, and keep that state. You can open the lid yourself or wait for the caregiver. Since waking up is conscious, the piston is moved by holding the rubber ball with a light grip and the switch S17 is turned on. If it still does not stop, the piston may be moved with a strong gripping force to turn on the switch S16, and the rotation of the container may be stopped in two stages.

The function selection rotary switch S4 may be switched to 2, and the piston may be moved by only grasping the rubber ball with a light gripping force to turn on the switch S17.

As the safety switch S5, there is a laser beam or wire around the container, and it operates when a person interrupts it and touches it. When it is difficult for conscious care recipients, it is better to have a battery built-in alarm and a notification device to notify the outside even in the event of a power failure. The above-mentioned rubber ball type may be switched in three steps to turn on the switch and operate the alarm and notification device.

This care bed is friendly to both caregivers and care recipients, so it can be used not only at home but also in hospitals. It can also be used by healthy people and can automatically turn over even if the installation area is small. For example, a train, a vehicle, a ship, and an aircraft.
