Description

          The present invention relates to a stretcher used in a staircase, a corridor, a road or the like of a narrow house when transporting a care recipient such as a sick person.

          The transport of a care recipient such as a sick person includes a stretcher such as an ambulance, a stretcher in a hospital, a wheelchair generally used indoors and outdoors, or a reclining wheelchair.

          These ordinary stretchers or wheelchairs are effective means of transportation on planes, gentle slopes, or places with small steps, but are specially provided for use on steep steps or indoor stairs. is not. At present, the stairs are moved by using a slope for stairs, or lifted by human power from the front and rear or from the left and right.

          In a narrow and steep place such as a staircase in a house, a normal stretcher is long and difficult to transport, and it is difficult to move a wheelchair on stairs by placing caregivers in front, back, left, and right.

          In addition, people with serious illness, loss of consciousness, broken bones, people with contracture on the body, people who develop pain in the whole body by just touching them, holding or carrying a narrow staircase such as a house with human power It is difficult to transport them. If such care recipients are to be held only with arm strength, the risk of fractures and pressure on affected areas will be borne by people with osteoporosis and the like.

          Various stretchers have been devised for transporting such care recipients on stairs. However, the transfer on the stairs reduces the labor for both the care recipient and the caregiver who moves the stairs, and there is no stretcher that can be used safely and easily.

      The problem to be solved is the physical burden of transporting care recipients such as those with sudden illnesses, and maintaining a comfortable posture while keeping the care recipient sleeping safely on a stretcher, even on steep and narrow stairs. And reducing the labor of the caregiver on the transport side and transporting it safely and more easily.

      While the stretcher can be used in a place such as a narrow staircase, it can be used at the same time in a room, a hallway, or on a road, and can be transferred to a car as it is.

      When transporting care recipients while lying down or in a posture similar to that, in order to change the direction in corridors and landings of houses, etc., it is required to satisfy the function of a stretcher while being compact and small. The

      When a caregiver moves a stretcher with a caregiver on a narrow staircase, the work must be done by two people from the top and bottom of the stairs, making it easy and safe for two people to work in an unstable position due to the level difference of the stairs. A stretcher with a structure that can be made is required. What realizes this safe and easy work is how to provide a gripping part for stabilizing the stretcher in an unstable place such as a staircase.

      Although it is a compact and small stretcher, it can handle various body types such as different heights of the care recipient to be transferred, and the stretcher itself is easy to operate for the caregiver, while the structure of the stretcher requires care It must reduce the burden of transporting caregivers while ensuring human safety.

          In the present invention, it is composed of a frame made of light metal pipes or rods such as aluminum, the stretcher is made compact and short, and even if the care recipient sleeps on the stretcher by folding the knee as shown in FIG. The stretcher seat and the four-sided frame keep the care recipient on the stretcher in a stable posture within the frame, and at the same time, with a steep slope and high stairs, the stretcher does not fall forward as shown in FIG. The frame arrangement angle was set to θ1 so that it was possible.

    In order to reduce the stretcher size to about half of the normal adult seat height and to keep the care recipient safe on the stretcher, the seat S is loosened between the support frame F1 and the support frame F2 as shown in FIG. And stretched in a hammock. The loose sheet S and the support frame F1 prevent the care recipient from slipping at the buttocks, and the left and right stretcher body frames F prevent the left and right falls. In addition, when the stretcher body is set up with the leg C, the care recipient is kept in a sitting position so that it can be used as a sitting chair or a wheelchair.

      The present invention provides a stretcher in order to make a caregiver's transportation means safe and easy while also allowing a care recipient to stay asleep while moving in a staircase even in a steep place such as stairs. A leg C and a suspension hand A4 are installed on the main body, a leg gripping part Ca, a leg movable gripping part Cb and a suspension hand gripping part A1, A2 and a suspension hand movable gripping part A3 are provided on the leg C. It was.

    A four-wheel caster is attached to the leg C of the stair stretcher so that it can be used not only as a seat chair but also as a wheelchair in a room or hallway.

      Among the plurality of gripping portions for making it easier for the caregiver on the stairs to transfer the stair stretcher during the transfer on the stairs and reducing the caregiver's labor caused by the steps of the stairs, the lifting hand movable gripping portion A3 The leg movable gripping portion Cb has a telescopic movable structure.

      About each holding | grip part, the length corresponding to the stretcher width which is more than a pillow width and a shoulder width was given so that the balance of the left and right of the moving stretcher could be corrected at the position of the holding part.

    The first suspender gripping part A1 of the suspender A4 connected to the pillow movable frame F3 is separated by one stairs up to the extent that it does not hit the head or face of the care recipient on the pillow M. The gripping part A2 is further separated from the suspension gripping part A1 by one step of the stair lift, and the movable hand gripping part A3 is extended from the suspension gripping part A2 to the length corresponding to two steps of the stair lift by the sub-tube-type slide bar P. Connect so that it can be stretched. The lifter movable gripping part A3 of the lifter A4 extends from the pillow movable frame F3 to an upper position corresponding to four steps of the stair lift, that is, the average hip joint height of the caregiver, and the length of the lifter 4 is about 90 cm. To the extent.

      When the suspender A4 is used on the stairs, it is almost vertical and tilted slightly to the stairs side, fixed with the screw hole N1 of the pillow M and the fixing screw N of the suspender frame A, and the stretcher is inclined almost vertically. Move along.

      The leg gripping portion Ca of the front leg frame C1 installed on the support frame F1 is spaced from the support frame F1 by a distance corresponding to one step of the staircase lifting, and the leg movable gripping portion Cb is further equivalent to one step of the staircase lifting than the gripping portion Ca. Can be extended downward by a slide rod P having a subtubular structure. The leg movable gripping portion Cb extended by the slide rod P of the front leg frame C1 extends downward from the support frame F1 to a position corresponding to two steps of the stair lift and forwards by two steps of the stair tread surface of the caster with brake. Although not shown in the drawing, the slave tube type slide rod P has a plurality of screw holes N1, and can be fixed by sliding with a fixing screw installed in the front leg frame C1.

      Although it is a compact and short stair stretcher, it can be used for people with large heights. A child-movable slide rod P with a pillow movable frame F3 with a fixed pillow M inserted into the cavity of the stretcher body frame F is used. I was able to cope with it by sliding and extending. Although not shown in the drawing, the slave tube type slide rod P has a plurality of screw holes N1 for fixing screws N, and the length of the stretcher in the height direction is adjusted by the fixing screws installed on the stretcher body frame F. And fix.

      For the sheet S of the stretcher, it is preferable to use a material that is moderately flexible and strong and has a stain-proofing process, such as cloth, so that the pressure points on the stretcher of the care recipient can be dispersed. Moreover, the net | network etc. of an equivalent material may be sufficient.

    As shown in FIG. 5, the left and right stretcher body frames F are arranged so that the support frame F1 prevents the care recipient from slipping down by loosening and stretching the seat S so that the waist of the care recipient sinks from the body frame. The left and right sides of the care recipient were loosened to the extent that they would surround the buttocks and shoulders.

      In order to stabilize the head and body of the care recipient on the stretcher, the pillow M was U-shaped.

      Although not shown in the drawings, seat belts are installed from the chest to the abdomen so that they can be attached to and detached from the pair of stretcher body frames F to prevent careless persons who are moving on the stretcher from inadvertently moving and preventing falling. .

      Although not shown in the drawings, the caster T1 that is the front wheel is a free caster, and the caster T2 that is the rear wheel is a caster with a brake so as not to rotate and take off from the stairs while riding on the stairs. did.

      Although not shown in the drawings, the suspension hand A4 rotates around the pillow movable frame so that it can be fixed with a string or the like on the back of the seat S, and the suspension hand A4 and the leg C are detached from the stretcher main body when stored. Made possible.

          By loosening the seat S installed as a compact stretcher, it is possible to stably hold a care recipient like a hammock, so it is possible to move in narrow places such as stairs that could not be transferred with a normal stretcher. Not only can the direction change, but it is possible to tilt the stretcher forward so that it slides down on a normal stretcher, that is, it can be tilted until it looks like a sitting chair, so it is a place that is narrower than the full length of the stretcher It becomes easy to transfer.

    As shown in Fig. 5, by loosening the stretcher sheet S, the body of the care recipient is surrounded by a frame from the front, back, left and right, and it is suspended in the air like a hammock. The body of the care recipient can be transported more stably with close contact with the sheet S against left and right shaking.

      In the present invention, when the caregiver transports the stairs stretcher requiring care from the top to the bottom of the stairs, a plurality of caregiver gripping part frames are provided, and the length of the slide rod P having a child tube structure is arbitrarily set. By adjusting, the caregiver can move the front gripping portion Ca and the front leg movable gripping portion Cb of the front leg frame C1 from the bottom of the stair stretcher, and the suspension hand gripping portions A1 and A2 of the suspension hand A4 from the top of the staircase. In addition, the gripper can be operated up and down in the range of the position of the caregiver's waist and the position one step below the waist of the caregiver movable gripper A3. This makes it possible for the caregiver to transfer without being bent more deeply than necessary, or without being forced to take a posture such as unreasonable stretching, thus reducing the labor of the caregiver and making the work safe. Can be a thing.

      In the present invention, when a caregiver moves on a stair stretcher from the top to the bottom of a staircase, the caregiver is provided with a plurality of caregiver grip portions, and the length of the slide rod having a child tube structure is arbitrarily set. The caregiver should be able to transport the care recipient in a stable and constant state even on a slope or a large step like a staircase from a flat ground. Can do.

      By fixing the suspender A4 with the screw hole N1 on the outer surface of the pillow M and the fixing screw N of the frame A, a carer on the head side of the caregiver needs to be shaken before and after the stretcher body on the stairs during transfer. In addition to preventing the stretcher from tipping forward due to excessive lifting of the suspension hand, it is possible to adjust the movement back and forth during the substantially vertical transfer.

    In the present invention, since the grip portion has a thickness and a length that are easy to grip, the left and right balance of the stretcher can be corrected and held, and the stretcher can be stabilized.

    In the present invention, since the sheet S is installed like a hammock, the stretcher sheet S can separate and absorb the vibrations of the front and rear and the right and left while being transferred. Therefore, it is possible to provide a stretcher transfer means that is kind to a care recipient.

    Since the leg C is detachable, the stretcher can be moved in a narrower place.

    When the caregiver operates the stretcher on a flat surface, the stretcher can be moved while maintaining the stretcher horizontally with the two casters of the rear leg frame C2, and can be operated by one caregiver.

          By loosening the stretcher sheet S, a wide area from the care recipient's thigh and waist to shoulder is in close contact with the sheet S, so that the body pressure points of the care recipient on the stretcher can be dispersed.

    By adjusting the length of the slide rod of the front leg frame C1, the stretcher body can be reclined backward from the seated chair state, and an arbitrary reclining angle can be selected.

          By making the pillow M U-shaped, not only can the head of the care recipient be stabilized, but inadvertent movement of the entire body can be prevented and it can be easily held in the center of the stretcher.

It is a general view of the stretcher for stairs. It is the usage figure which extended FIG. 1 with the slide rod. It is a layout view of the mounting angle of each frame. It is the figure which fixed the hanger with the screw. It is explanatory drawing when a stretcher is used horizontally. It is explanatory drawing which transfers the stretcher for stairs with a stairs.

      This stretcher is a rectangle composed of a pair of stretcher main body frames F, a support frame F1, and a support frame F2. A slide rod P is inserted into the pipe cavity of the stretcher main body frame F outside the support frame, A rectangular movable frame F3 joined to the end portion of the slide bar P is a rectangle having a U-shaped connection. A sheet S having the width of the frame with the support frame F1 and the support frame F2 as a fulcrum is installed with a slack like a hammock.

  Furthermore, a suspension hand A4 is installed on the pillow movable frame F3, and a leg C is installed on the support frame F1 on the buttocks side, and they constitute a stair stretcher. However, the suspender A4 can be fixed at an angle that is vertical or inclined to the stairs side by the outer surface screw hole of the pillow M and the fixing screw of the frame A according to the inclination of the stairs, and can rotate around the pillow movable frame F3. Although possible and not shown in the drawing, it is assumed that it can be rotated and stored in the lower part of the sheet S, fixed with a string or the like, and detachable from the pillow movable frame F3.

    Although not shown in the drawing, the leg C is also detachable when stored.

          This stretcher is a sheet S as shown in FIG. 5, deep enough to allow the care recipient's thigh and waist to sink from the support frame F1, and supports the shoulder at the support frame F2, while the pillow movable frame F3 It is a compact configuration that supports the head.

    This stretcher becomes a seat chair by providing the legs C, and becomes a wheelchair by installing the casters T1, T2. Further, by adjusting and fixing the length of the slide frame of the front leg frame C1, the stretcher body frame F can be tilted backward and reclined.

      The length of the suspension hand A4 connected to the pillow movable frame F3 of this stretcher is connected so that the length of the movable gripping portion A3 can be adjusted and fixed by sliding the slide rod P having a child tube structure. . The movable gripping portion A3 is configured to extend upward from the pillow movable frame F3 to the equivalent of four steps of staircase lifting.

      The support frame F1 on the stretcher frame side has legs C, and a pair of casters T1 and a caster T2 with brakes are installed at the lower ends of the pair of front leg frames C1 and rear leg frames C2 constituting the legs, respectively.

      The thickness of each gripping part frame of the suspension A4 is about 3 cm in diameter, and the length is a pipe of about 30 cm which is the width of the pillow M.

      A gripping portion Ca is connected to the pair of front leg frames C1, and a slide rod P is inserted into the vip cavity of the front leg frame C1, and a leg movable gripping portion Cb is connected to the end thereof, and further to the end thereof. Is connected to a caster T1. The thickness of the gripping part frame is about 3 cm in diameter, and the length is about 50 cm.

      The width of the stretcher sheet S is about 50 cm corresponding to the width of the support frame F.

      The total length of the suspension hand A4 from the pillow movable frame F3 to the movable gripping part A3 is about 90 cm.

      The length L1 of the stretcher main body frame F is about 80 cm.

    When the slide bar of the front leg frame C1 is not extended, the length H1 to the tip of the caster T1 is set to about 36 cm. When used as a seat chair or wheelchair, the height is such that it can be easily seated.

      The leg gripping portion Ca of the front leg frame C1 is set apart from the support frame F1 by about 22 cm corresponding to one step of the stair lift. The leg movable gripping portion Cb is further extended by about 22 cm corresponding to one step of the stair lift by sliding and extending the slide rod of the subtubular structure, and from the support frame F1 in the direction of an angle of θ2 of about 39 ° from the rear leg frame. About 44cm, and extends from the caster with brakes away from the stairs corresponding to the two steps of the stairs.

    The length of the rear leg frame C2 of the stretcher to the tip of the caster T2 with a brake is about 53 cm.

    In FIG. 3 when the stretcher is viewed from the side, the arrangement of the pair of main body frames F, the pair of front leg frames C1, and the pair of rear leg frames C2 is such that the angle θ1 is about 101 ° when the support frame F1 is a fulcrum. Connected. However, the angle θ1 inevitably increases as the stair inclination angle increases to stabilize the stretcher on the stairs with two-point support of the caster with brake and the pillow movable gripping portion.

    Since the lifting hand gripping portion A1 of the lifting hand A4 is located on the head of the care recipient in use, it is equivalent to the pillow movable frame F3 so that the caregiver does not touch the head or face even if the gripping portion is gripped. Install at a sufficient distance.

    The caster T1 installed at the lower end of the slide rod P having a child tube structure of the front leg frame C1 is about 58 cm in H2 to the grounding point of the caster T1, which is the total length of the front leg frame C1 after sliding and extending. is there.

    A slide bar P having a plurality of screw holes N1 for connecting the lifter movable gripping portion A3, the front leg movable gripping portion Cb, and the pillow movable frame F slides at the length of each rod, and the fixing screw N of each frame is fixed. And can be fixed with screw holes.

      The pillow M has a total length of about 30 cm so that the head of the care recipient during movement is stable and the nose of the care recipient does not touch the hanging hand frame A even if the head is rotated. The center is a U-shaped recess.

      Other forms. The material of the pipe may be a carbon glass material, and the length, the width of the sheet S, the length of the legs, and the attachment angles θ1 and θ2 are shown as models used for a residential staircase with a staircase inclination of about 50 degrees. Therefore, the length of the stretcher body frame F, the length of the leg C frame, and the mounting angles θ1 and θ2 are basically the inclination angle of the stairs and the kick-up as long as it can be used by sitting on a chair, wheelchair or reclining. As a stretcher according to the size of the tread and the method of fixing the slide rod of the child tube structure can be changed.

      This example is an example when the stretcher is on the stairs. As shown in FIG. 2, the movable gripping part A3 of the suspension hand A4 is slid and extended, and the head of the care recipient is overhead as shown in FIG. 6 with the screw hole N1 on the outer surface of the pillow M and the fixing screw N of the suspension frame A. Fix it at a position slightly tilted to the stairs side from the vertical top of about 4 steps on the stairs kick. The position of the lifting hand movable gripping part A3 is as follows. The caregiver standing upright by placing his feet up one step above the stairs tread where the head of the care recipient is located on the upper side of the stairs, hangs at the waist level. This is the height at which the hand movable grip portion A3 is gripped. This posture of the caregiver is a posture immediately after moving the stretcher from the bottom to the top, and a posture immediately before moving the stretcher from the bottom to the bottom. In other words, the basic operation of the caregiver when moving the stair stretcher is about 22 cm below the level corresponding to one step with the position of the gripping part raised from the waist height to the staircase, and braking at one step of the staircase. The attached caster and the head of the care recipient are moved substantially vertically so as not to hit the corner of the stairs. The caregiver can move up and down the stairs at a time in multiple steps if the two caregivers breathe in a reasonable movement without bending or stretching the waist too much.

      Similarly, when the caregiver supports the stair stretcher from below, the movable gripping portion Cb of the front leg frame C1 is approximately 44 cm below the support frame F1, and is horizontally equivalent to two steps of the stair tread from the caster with brake. At the front, the caregiver on the lower side of the stairs reaches the position of the waist when standing upright, and the caregiver stands with both feet on the tread surface four steps down from the caster with brake. From the posture, the caregiver raises one leg up to the floor and climbs with the power of his legs and arms, and downstairs one leg lowers and operates the gripping part with the power of his legs and arms. Are vertically moved in the vertical direction.

      Since the length of the suspension gripping part is about 30 cm and the length of the leg gripping part is about 50 cm, the left and right unbalance of the stretcher can be adjusted by selecting the gripping position to the left and right.

      As shown in FIG. 3, the stretcher leg C is connected such that the front leg frame C1 and the rear leg frame C2 are at an angle θ2, and the rear leg frame C2 and the main body frame F are at an angle θ1, so that they can be seated as a seat chair. The center of gravity of the care recipient on the stretcher is positioned on the stairs side of the head of the care recipient from above the grounding point of the caster T2 with the brake when the stretcher is landed on the stair tread surface with the caster T2 with brake. The angle is θ1. This allows the stretcher to rest on the stairs with the two-point support of the caster T2 with brake and the pillow movable frame, so that the stairs do not slide down.

      At the beginning of climbing the stairs, the caregiver above the stairs rolls the caster T2 with brake while holding the pillow movable frame F3, and grounds the pillow movable frame F3 or the pillow on the third stage of the stairs. At this point, the caregiver on the leg side brakes the caster T2 with brake. Since the stretcher is supported and stabilized on the stairs in the state by the angle θ1, the caregiver on the upper side of the stairs slides the movable handle A3 so that the foot is positioned at the head of the care recipient. When standing upright one step further from the tread surface, stretch to reach your waist. Thereafter, the caregiver holds the movable gripping part A3 in a posture in which the patient needs to be further raised by one step and bends his / her waist slightly, and then lifts it up one step. The caregiver on the lower side of the stairs holds the support frame F1 and raises the stretcher substantially vertically at the first step of the first stairs in accordance with the timing of both caregivers. At this time, the head of the care recipient climbs one step and lands on the stairs one step below the caregiver's feet on the stairs. The caregiver on the stairs repeats the same action. Next, the caregiver under the stairs grasps and lifts the gripping part Ca, operates the gripping part Cb that is further extended by sliding, and from the position where the caregiver under the stairs bends and grips a little, the limbs and back muscles Lift up the stairs one step as if stretching.

      The caregiver who has reached the landing on the stairs shortens the movable gripping part A3 by one step, further moves the gripping part to A2 and A1, pulls up the stretcher, and finally supports the pillow movable frame F3. Then, casters with brakes on the rear legs of the stretchers are landed on the landing on the stairs. At that time, the caregiver below the stairs slides the movable gripping portion Cb to shorten the front leg and releases the brake of the caster with brake. The caregiver on the floor may move by moving the caster while supporting the frame F3, and then move it on the floor as a four wheelchair.

      The reason why the suspension A4 can be fixed to the stretcher main body by the fixing screw on the side surface of the pillow is to stabilize the stretcher during the movement of the stairs. Because the caregiver's operation on the staircase lifts the stretcher too much to break the balance of the stretcher and prevent it from falling forward, the suspender A4 not only needs to be lifted, but it is also necessary to suppress excessive lifting. is there.

      In the case of transfer on a flat surface or use in a wheelchair, the suspender A4 is rotationally housed on the back surface of the sheet S and fixed with a string or the like so as not to interfere with the stretcher operation.

      The plurality of screw holes N1 of the slide tube having a child tube structure is for selecting an appropriate position of the movable gripper according to the height and body shape of the care recipient and the caregiver.

      The caregiver slides the slide bar P in consideration of his / her height and adjusts the movable gripping part, and the caregiver is most effective in operating the stretcher up and down with the fixing screw N and the optional screw hole N1. The position where it is easy to put can be selected.

      According to the height of the care recipient, slide the child slide slide rod P of the pillow movable frame F3, place the head of the care recipient on the pillow, and move the pillow with the fixing screw N and screw hole N1 of the body frame F The frame F3 is fixed.

      In this example, a stair stretcher is used as a seat chair or a wheelchair in a room, a corridor, a road or the like using four casters of leg C. In this case, the caregiver took the care recipient like a sitting chair or a wheelchair, and when using it as a stretcher, it required two caregivers, but one caregiver grasped the pillow movable frame F3. It is possible to operate.

    By sliding and fixing the slide bar of the front leg frame C1, it can be used like a seat chair or a wheelchair reclining backward from a seat chair or a wheel chair. It can also be adjusted to the desired angle for reclining.

      In this example, the caster T2 with a brake for the rear wheel is used to transfer the stretcher body in a room, a corridor, a road or the like while keeping the stretcher body substantially horizontal. In this case, the caregiver puts the care recipient from the seated state like a stretcher, and one caregiver holds the pillow movable frame F3 and floats the front wheel caster T2 with one brake. To operate the stretcher as a motorcycle.

      A care recipient who needs a stretcher cannot move by himself because his body is skeletally weak or unconscious. In such a case, when the transport is performed in a narrow passage or staircase in the house, the level of the stretcher may not be maintained at a normal length because the staircase is steep. If a stretcher cannot be used, it is not the case that it is not carried out by a method such as carrying it on the back, but if there is contracture on the body, it may not even be possible, and it may be injured by the care recipient. May impose risks.

      Patients who are in need of care, etc. want to move the stairs by the operation of care helpers and their families, such as daily hospital visits and outpatient clinics besides emergency. However, there are no stretchers that can be safely operated by a caregiver with a narrow staircase like a Japanese house, and there is no stretcher that can be safely transported to the care recipient, so it is actually going out even for hospitalization. is there.

    As a result of the increase in home care for the elderly, the need for care recipients and emergency patients who cannot move up the stairs on their own have increased in the narrow corridors and upstairs on the stairs. In Japan's residential environment, simple elevators cannot be installed on the stairs, and the risk of moving on the stairs will continue to increase.

    The stair stretcher of the present invention has been devised as a stretcher that can reduce the safety of stairs movement of a care recipient such as a patient and the labor burden of a caregiver responsible for transfer. This stair stretcher can be used not only on stairs but also as a sitting chair or reclining wheelchair, and it is equipped with a lift, slope, etc., and rides directly to a care vehicle equipped with a fixing device such as a wheelchair to go directly to the hospital. can do. This is a safe and comfortable transfer tool from the stairs to the vehicle for both the care recipient and the caregiver.

The present invention relates to a stretcher suitable for use on a staircase, a corridor, a road or the like of a narrow house when transporting a care recipient such as a sick person.

          The transport of a care recipient such as a sick person includes a stretcher such as an ambulance, a stretcher in a hospital, a wheelchair generally used indoors and outdoors, or a reclining wheelchair.

          These ordinary stretchers or wheelchairs are effective means of transportation on planes, gentle slopes, or places with small steps, but are specially provided for use on steep steps or indoor stairs. is not. At present, the stairs are moved by using a slope for stairs, or lifted by human power from the front and rear or from the left and right.

However, in a narrow and steep place such as a staircase in a house, a normal stretcher is long and difficult to transport, and it is also difficult to place caregivers on the front and back of the wheelchair and to move the stairs.

In addition, people with serious illness, loss of consciousness, broken bones, people with contracture on the body, people who develop pain in the whole body by just touching them, holding or carrying a narrow staircase such as a house with human power It is difficult to transport them. If a caregiver tries to hold such a care recipient with only his / her arm strength, he / she bears the risk of osteoporosis or the like due to a fracture or pressure on the affected area.

Various stretchers have been devised for transporting such care recipients on stairs. However, it is a fact that there is no stretcher that can be used safely and easily because the transfer on the stairs reduces the labor for both the care recipient and the caregiver who moves the stairs.

Japanese Patent No. 2794278 Japanese Patent No. 3172682 Japanese Patent No. 3492982

      The problem to be solved is the physical burden of transporting care recipients such as those with sudden illnesses, and maintaining a comfortable posture while keeping the care recipient sleeping safely on a stretcher, even on steep and narrow stairs. And reducing the labor of the caregiver on the transport side and transporting it safely and more easily.

For each gripper, so as to unbalance left and right stretcher moving can correct balanced by the position of the grip portion, and to have a length of responsible rack width is shoulder pillow width or more.

The first of the first stage of the hanging hand grip portion A1 of the hand strap A4 which is connected to the pillow frame F3 is, the amount of one stage of riser staircase to the extent that does not hit the main caregiver of the head and face away from the city on the pillow M, in the second stage gripper A2 separates one step risers further staircase from the hand strap gripper A1, from the hand strap gripper A3 is hand strap gripper A2 than two stages of the length of the riser staircase, slidable like a car antenna rod The slide rod P is connected so that it can be extended. Hand strap gripper A3 of the hand strap A4, the position of the four stages on lateral risers stairs pillow frame F3, i.e. extend to the average hip height of a caregiver, the length of the hand strap 4 is about 90cm.

      When the suspender A4 is used on the stairs, it is almost vertical and tilted slightly to the stairs side, fixed with the screw hole N1 of the pillow M and the fixing screw N of the suspender frame A, and the stretcher is inclined almost vertically. Move along.

The leg gripping portion Ca of the front leg frame C1 installed at the connecting portion of the stretcher frame and the support frame F1 is spaced apart from the support frame F1 by one step up the staircase, and the front leg gripping portion Cb is further than the gripping portion Ca. to the length of one stage of riser staircase can be extended downward in a slide rod P. The front leg gripping portion Cb extended by the slide rod P of the front leg frame C1 is a staircase that is two steps away from the stepped surface on which the caster with brake is landed , and vertically downward from the support frame F1 to the distance of two steps of the staircase. It grows on the tread . Although not noted in the drawings, the slide bar P has a plurality of screw holes N1, can be fixed to slide with fixing screws installed in the front leg frame C1.

Yet shorter the stretcher stair compact, so that it can be used corresponding to a large human height, slide the pillow frame F3 of a fixed pillow M in the inserted slide bar P in the pipe cavity of a litter frame F It was to be able to deal with and if Shin Te. Although not shown in the drawings, the slide bar P has a plurality of screw holes N1 for fixing screws N, and the fixing screws installed in the supporting frame F are adjusted and fixed in the height direction of the supporting frame .

In order to disperse the pressure points on the back of the care recipient, the stretcher sheet S should be made of a material that is moderately flexible and strong, such as cloth, and that has been processed to prevent contamination. Moreover, the net | network etc. of an equivalent material may be sufficient.

As shown in FIG. 5, the left and right stretcher frames F are arranged so that the support frame F <b> 1 prevents the care recipient from sliding down by loosening and stretching the seat S so that the waist of the care recipient sinks from the body frame. The left and right sides of the care recipient were loosened to the extent that they surrounded the buttocks and shoulders.

      In order to stabilize the head and body of the care recipient on the stretcher, the pillow M was U-shaped.

Although not shown in the drawings, seat belts are installed from the chest to the abdomen so that they can be attached to and detached from the pair of stretcher frames F in order to prevent inadvertent movement of the care recipient who is moving on the stretcher and to prevent falling.

      Although not shown in the drawings, the caster T1 that is the front wheel is a free caster, and the caster T2 that is the rear wheel is a caster with a brake so as not to rotate and take off from the stairs while riding on the stairs. did.

Although not shown in the drawings, the suspension hand A4 rotates around the pillow frame so that it can be fixed with a string or the like on the back of the seat S, and the suspension hand A4 and the leg C can be detached from the stretcher body when stored. I made it.

          By loosening the seat S installed as a compact stretcher, it is possible to stably hold a care recipient like a hammock, so it is possible to move in narrow places such as stairs that could not be transferred with a normal stretcher. Not only can the direction change, but it is possible to tilt the stretcher forward so that it slides down on a normal stretcher, that is, it can be tilted until it looks like a sitting chair, so it is a place that is narrower than the full length of the stretcher It becomes easy to transfer.

As shown in Fig. 5, by loosening the stretcher sheet S, the body of the care recipient is surrounded by a frame from the front, back, left and right, and it is suspended in the air like a hammock. The body of the care recipient can be transported more stably with close contact with the sheet S against left and right shaking.

A U-shaped front leg gripping part frame is connected to each other, and casters T1 are connected to the ends of the slide bars . The thickness of the gripping part frame is about 3 cm in diameter, and the length is about 50 cm.

The width of the stretcher sheet S is about 50 cm of the width of the support frame F.

The total length of the suspension hand A4 from the pillow frame F3 to the suspension hand gripping part A3 is about 90 cm.

The length L1 from the support frame F1 of the stretcher to the pillow frame F3 is about 80 cm.

    When the slide bar of the front leg frame C1 is not extended, the length H1 to the tip of the caster T1 is set to about 36 cm. When used as a seat chair or wheelchair, the height is such that it can be easily seated.

The leg gripping portion Ca of the front leg frame C1 is installed so as to be separated vertically downward by about 22 cm for one step when viewed from the support frame F1. The front leg gripping portion Cb extends downward so as to be further separated by about 22 cm in the vertical direction as viewed from the front leg gripping portion Cb by sliding and extending the slide rod like an antenna rod of an automobile. supposed to leave about 44cm vertically below stairs Keage two stages when viewed from F1, the opening of the rear leg frame and the front leg frame C1 angle θ2 is an acute angle 39 ° so the wear on the stepped tread brake casters When viewed from the point, it is about 34 cm away from the bottom of the stairs .

    The length of the rear leg frame C2 of the stretcher to the tip of the caster T2 with a brake is about 53 cm.

In FIG. 3 when the stretcher is viewed from the side, the pair of stretcher frames F and the pair of rear leg frames C2 are connected at an opening angle θ1 of 101 °. However opening angle θ1, when stepped inclination angle increases, then landing a brake caster on stairs tread, also in order to freeze the stretcher on the stairs developing with two-point support in contact with pillow frame in the upper stair angle In order to place the center of gravity of the care recipient in the stairs side from the fulcrum of the rear leg frame , the opening angle is inevitably increased.

Since the hand grip part A1 of the hand lifter A4 is located on the head of the care recipient at the time of use, a considerable amount is taken from the pillow frame F3 so that the caregiver does not touch the head or face even if the hand grips the grip part. Install at a distance.

Other forms. Pipe material may be a carbon-glass material, length, width of the sheet S, the angle θ1 and θ2 opening length of the legs and is an illustration to be used in residential stair staircase inclined 5 0 degrees as a model Therefore, as long as it is within a range that can be used by sitting on a chair, wheelchair, or reclining, the length of the stretcher body frame F, the length of the leg C frame, and the opening angles θ1 and θ2 are basically the inclination angle of the stairs, It is possible to change the fixing method of the slide bar as a stretcher according to the size of the kick-up or tread.

This example is an example when the stretcher is on the stairs. As shown in FIG. 2, the hand grip A3 of the hand A4 is slid and extended, and the screw hole N1 on the outer surface of the pillow M and the fixing screw N of the hand frame A are used by the care recipient as shown in FIG. Fix it at a position that is slightly inclined to the stairs side from the top of the head, about four steps above the stairs kick. The position of the suspension gripping part A3 is that the caregiver who stands upright with his feet on the top of the staircase where the head of the care recipient is located above the staircase extends the posture and lifts the hand at the height of the waist This is the height at which the grip portion A3 is gripped . Ie the basic operation of the caregiver in moving the litter for stairs, in the range of about 2 2 cm between the bottom of one stage of the position and on the kick stairs waist height of the grip portion, stair one step In this case, the caster with brake and the head of the care recipient are moved substantially vertically so as not to hit the corner of the stairs. The caregiver can move up and down the stairs at a time in multiple steps if the two caregivers breathe in a reasonable movement without bending or stretching the waist too much.

If the caregiver supported by front leg gripper from below the stairs stretcher for stairs, standing on both feet tread down stairs three stages from the staircase tread surface to landing brakes casters. At that time, the front leg gripping part is at a position of the waist level in front of the upright caregiver, which is approximately 44 cm vertically below the support frame F1 . The caregiver supports the front leg grip and moves the stretcher up and down the stairs substantially vertically.

      Since the length of the suspension gripping part is about 30 cm and the length of the leg gripping part is about 50 cm, the left and right unbalance of the stretcher can be adjusted by selecting the gripping position to the left and right.

As shown in FIG. 3, the leg C of the stretcher has an acute angle of the opening angle θ2 between the front leg frame C1 and the rear leg frame C2, and an obtuse angle of the opening angle θ1 between the rear leg frame C2 and the stretcher frame F. They were connected so that they could be placed in a safe place. On stairs tread is landed brake caster T 2, also when placing the stretcher on the stairs developing with two-point support pillow frame F3 to land on the upper side of the stair angle, main caregiver of the position of the center of gravity on the stretcher, arranged from the vertical landing point of the brake casters T2 on the staircase side of the top of the main caregiver to an obtuse angle of so that an opening angle θ1. Depending on this, in two-point support of the, it is possible to rest the litter on the stairs, Rukoto to tumble the stairs to the lower no.

Stairs the upper side of the caregivers in stair climbing initially, to land a pillow frame F3 or pillow in the third stage stairs roll the brake casters T2 while holding a pillow frame F3. At this point, the caregiver below the stairs brakes the caster T2 with brake. Since the stretcher is supported on the stairs by the angle θ1 and is stationary , the suspender gripping part A3 is slid at this time, and the caregiver on the upper side of the stairs places the foot on the head of the care recipient. When standing upright one step further from the tread, stretch to reach the waist. Then stairs the upper side of the caregivers, gripping the hanging hand grip portion A3 in a slightly bowed posture and stance to the waist from the stairs tread of the main caregiver of the head of the further-higher of the main caregiver on a two-stage, Pull it up vertically one level. Stairs under side of the caregivers, the first of the stairs first stage holding the support frame F1, Ryakushide raise directly. At this time, the head of the care recipient climbs one step and lands on the stairs one step below from the caregiver's feet on the stairs. The caregiver on the stairs repeats the same action. The caregiver under the stairs next operates the front leg gripping portion Cb that holds the leg gripping portion Ca, lifts it by one step , and then slides and stretches to match the above-described continuous movement of the caregiver on the stairs. Te, from the position where the caregivers under the stairs to grip bent down a little waist, so as to stretch the limbs and spine lift to the next stair-higher.

The caregiver who has reached the landing on the stairs shortens the suspension gripping part A3 by one step, further moves the gripping part to A2 and A1, lifts the stretcher, and finally supports the pillow frame F3. Then, casters with brakes on the rear legs of the stretchers are landed on the landing on the stairs. At that time, the caregiver under the stairs slides the front leg gripping portion Cb to shorten the front leg, and releases the brake of the caster with brake. The caregiver on the floor may move by moving the caster while supporting the frame F3, and then move it on the floor as a four wheelchair.

The hand strap A4, is it can be fixed with the stretcher body fixed screw pillow aspect is to stabilize the stretcher in stair movement.

      In the case of transfer on a flat surface or use in a wheelchair, the suspender A4 is rotationally housed on the back surface of the sheet S and fixed with a string or the like so as not to interfere with the stretcher operation.

The plurality of screw holes N1 of the slide rod that can be slid like an antenna rod of an automobile is for selecting an appropriate position of the grip portion according to the height and body shape of the care recipient and the caregiver. .

The caregiver adjusts the gripping part by sliding the slide rod P in consideration of his / her height, and the caregiver moves the stretcher from the bottom of the stairs to the top with the fixing screw N and the optional screw hole N1. It is possible to select the position where the most effort can be made to move down.

In accordance with the height of the main caregiver, put the main caregiver of the head on the pillow and slide the slide can slide rod P as in the automobile antenna rod of pillow frame F3, and the fixing screws N of the stretcher frame F The pillow frame F3 is fixed by the screw hole N1.

In this example, a stair stretcher is used as a seat chair or a wheelchair in a room, a corridor, a road or the like using four casters of leg C. In this case, the caregiver took the care recipient like a seat chair or a wheelchair, and when using it as a stretcher, two caregivers were required, but one caregiver held the pillow frame F3. Can be operated.

    By sliding and fixing the slide bar of the front leg frame C1, it can be used like a seat chair or a wheelchair reclining backward from a seat chair or a wheel chair. It can also be adjusted to the desired angle for reclining.

In this example, the caster T2 with a brake for the rear wheel is used to transfer the stretcher body in a room, a corridor, a road or the like while keeping the stretcher body substantially horizontal. In this case, the caregiver lays the care recipient horizontally from the seated chair, and one caregiver holds the pillow frame F3 and rolls the caster T2 with one brake while the front wheel caster is floating. And operate the stretcher .

      A care recipient who needs a stretcher cannot move by himself because his body is skeletally weak or unconscious. In such a case, when the transport is performed in a narrow passage or staircase in the house, the level of the stretcher may not be maintained at a normal length because the staircase is steep. If a stretcher cannot be used, it is not the case that it is not carried out by a method such as carrying it on the back, but if there is contracture on the body, it may not even be possible, and it may be injured by the care recipient. May impose risks.

Patients who are in need of care, etc. want to move the stairs safely in daily hospital visits and places other than emergency. However, there are no stretchers that can be safely operated by a caregiver with a narrow staircase like a Japanese house, and there is no stretcher that can be safely transported to the care recipient, so it is actually going out even for hospitalization. is there.

    As a result of the increase in home care for the elderly, the need for care recipients and emergency patients who cannot move up the stairs on their own have increased in the narrow corridors and upstairs on the stairs. In Japan's residential environment, simple elevators cannot be installed on the stairs, and the risk of moving on the stairs will continue to increase.

    The stair stretcher of the present invention has been devised as a stretcher that can reduce the safety of stairs movement of a care recipient such as a patient and the labor burden of a caregiver responsible for transfer. This stair stretcher can be used not only on stairs but also as a sitting chair or reclining wheelchair, and it is equipped with a lift, slope, etc., and rides directly to a care vehicle equipped with a fixing device such as a wheelchair to go directly to the hospital. can do. This is a safe and comfortable transfer tool from the stairs to the vehicle for both the care recipient and the caregiver.

  The transport of a care recipient such as a sick person includes a stretcher such as an ambulance, a stretcher in a hospital, a wheelchair generally used indoors and outdoors, or a reclining wheelchair.

  These ordinary stretchers or wheelchairs are effective means of transportation on planes, gentle slopes, or places with small steps, but are specially provided for use on steep steps or indoor stairs. is not. At present, the stairs are moved by using a slope for stairs, or lifted by human power from the front and rear or from the left and right.

  However, in a narrow and steep place such as a staircase in a house, a normal stretcher is long and difficult to transport, and it is also difficult to place caregivers on the front and back of the wheelchair and to move the stairs.

  In addition, people with serious illness, loss of consciousness, broken bones, people with contracture on the body, people who develop pain in the whole body by just touching them, holding or carrying a narrow staircase such as a house with human power It is difficult to transport them. If a caregiver tries to hold such a care recipient with only his / her arm strength, he / she bears the risk of osteoporosis or the like due to a fracture or pressure on the affected area.

  Various stretchers have been devised for transporting such care recipients on stairs. However, it is a fact that there is no stretcher that can be used safely and easily because the transfer on the stairs reduces the labor for both the care recipient and the caregiver who moves the stairs.

Japanese Patent No. 2794278 Japanese Patent No. 3172682 Japanese Patent No. 3492982

The lifter movable gripping portion A3 is configured to extend upward from the pillow movable frame F3 to the equivalent of four steps of the stair lift.

Responsible for supporting the frame F1 of Kashiri side there is a leg C, a pair of front legs frame C1 constituting the leg, the lower end of the rear leg frame C2, each of the pair of casters T1, installing a brake caster T2.

  The thickness of each gripping part frame of the suspension A4 is about 3 cm in diameter, and the length is a pipe of about 30 cm which is the width of the pillow M.

The pair of front legs frame C1 leg gripper Ca is consolidated, and before each pipe cavity of the leg frame C1 by inserting the slide rod P, leg movable holding part Cb on the end of that is being consolidated, Furthermore both ends of its being connected castors T1. The thickness of the gripping part frame is about 3 cm in diameter, and the length is about 50 cm.

The width of the stretcher sheet S is about 50 cm corresponding to the width of the support frame F.

The total length of the suspension hand A4 from the pillow movable frame F3 to the suspension hand gripping part A3 extended is about 90 cm.

The length L1 of the stretcher main body frame F is about 80 cm.

  When the slide bar of the front leg frame C1 is not extended, the length H1 to the tip of the caster T1 is set to about 36 cm. When used as a seat chair or wheelchair, the height is such that it can be easily seated.

Front leg gripper Ca leg frame C1 is installed off the support frame F1 or al floor stage risers one step equivalent to about 22 cm. The leg movable gripping part Cb is further extended by about 22 cm corresponding to one step of the stair lift by sliding and extending the slide rod P having a child tube structure , and is supported in the direction of an opening angle of about 39 ° of θ2 from the rear leg frame C2. It extends from the frame F1 about 44 cm away from the caster T2 with brake and away from the stairs corresponding to the two steps of the stairs .

  The length of the rear leg frame C2 of the stretcher to the tip of the caster T2 with a brake is about 53 cm.

In FIG. 3 when the stretcher is viewed from the side, the arrangement of the pair of stretcher main body frames F, the pair of front leg frames C1, and the pair of rear leg frames C2 has an opening angle θ1 of about 101 when the support frame F1 is a fulcrum. Linked at °. However, the opening angle θ1 inevitably increases as the stair inclination angle increases to stabilize the stretcher on the stairs with two-point support of the caster T2 with brake and the pillow movable frame F3 .

Since the lifting hand gripping portion A1 of the lifting hand A4 is located on the head of the care recipient in use, it is equivalent to the pillow movable frame F3 so that the caregiver does not touch the head or face even if the gripping portion is gripped. Install at a sufficient distance.

The caster T1 installed at the lower end of the slide rod P having a child tube structure of the front leg frame C1 is about 58 cm in H2 to the grounding point of the caster T1, which is the total length of the front leg frame C1 after sliding and extending. is there.

Other forms. The material of the pipe may be a carbon glass material, and the length, the width of the sheet S, the length of the legs and θ1 and θ2 are shown as models for use in residential stairs with a stairs inclination of about 50 degrees. The length of the stretcher main body frame F, the length of the leg C frame, and the opening angles θ1 and θ2 are, in principle, the inclination angle of the stairs, kicking up as a stretcher according to the size of the surface, also the method of fixing the slide bar of the child-tube structure can be changed.

This example is an example when the stretcher is on the stairs. As shown in FIG. 2, the movable hand gripping part A3 of the hand A4 is slid and extended, and the person requiring care as shown in FIG. 6 with the screw hole N1 on the outer surface of the pillow M and the fixing screw N of the hand frame A. At a position that is slightly inclined to the stairs side from the vertical top of about four steps above the stairs kick. The position of the lifting hand movable gripping portion A3 is such that the caregiver standing upright by placing his feet up two steps above the stairs tread where the head of the care recipient is located on the upper side of the stairs is at the waist level. This is the height at which the movable hand gripping part A3 is gripped. This posture of the caregiver is a posture immediately after moving the stretcher from the bottom to the top, and a posture immediately before moving the stretcher from the bottom to the bottom. That is the basic operation of the caregiver in moving the litter for stairs, in the range of about 22cm between the lower position of one stage corresponding to on kick stairs waist height of the grip portion, the brake in stair one step The attached caster and the head of the care recipient are moved substantially vertically so as not to hit the corner of the stairs. The caregiver can move up and down the stairs at a time in multiple steps if the two caregivers breathe in a reasonable movement without bending or stretching the waist too much.

When the caregiver supports the stair stretcher from below the stairs with the front leg gripping part, the leg movable gripping part Cb of the front leg frame C1 is about 44 cm below the support frame F1, and the two steps of the stair tread from the caster with brake Appropriately horizontally ahead, it reaches the position of the waist when the caregiver under the stairs stands upright, and the caregiver stands with both feet on the tread below the stairs difference 4 steps from the caster with brake. From the posture, the caregiver raises one leg up to the floor and climbs with the power of his legs and arms, and downstairs one leg lowers and operates the gripping part with the power of his legs and arms. Move vertically up and down the stairs.

  Since the length of the suspension gripping part is about 30 cm and the length of the leg gripping part is about 50 cm, the left and right unbalance of the stretcher can be adjusted by selecting the gripping position to the left and right.

Tankaashi C, as in FIG. 3, before the angle theta 2 to open the leg frame C1 and rear leg frames C2, an angle theta 1 open in the rear leg frame C2 and litter body frame F, it is also enshrined as chair seat They were connected as follows. When the stretcher on the stairs developing was landing on the stairs tread by the brake casters T2, the main caregiver of the position of the center of gravity on the stretcher is located on the head staircase side of the main caregiver from the brake casters T2 contact point on the vertical Such an opening angle θ 1 is used. This fact, in two-point support of the brake casters T2 and pillows movable frame F3, it is possible to enshrine litter on the stairs, Rukoto slide down stairs without.

Stairs the upper side of the caregivers in stair climbing initially, to ground the pillow movable frame F3 or pillow in the third stage stairs roll the brake casters T2 while holding a pillow movable frame F3. At this point, the caregiver below the stairs brakes the caster T2 with brake. The stretcher is supported by the staircase in that state by the opening angle θ1 and is stable . At this time, the lifter movable gripping portion A3 is slid, and the caregiver on the upper side of the staircase places the foot on the position of the head of the care recipient. When standing upright two steps above the tread surface, stretch out to come to the waist position. Thereafter, the caregiver holds the lifting hand movable gripping portion A3 in a posture in which he stands on a step further than the care recipient and slightly bends his / her waist and pulls it up one step. The caregiver on the lower side of the stairs holds the support frame F1 and raises the stretcher substantially vertically at the first stage of the first stairs , with both caregivers matching the timing . At this time, the head of the care recipient climbs one step and lands on the stairs one step below from the caregiver's feet on the stairs. The caregiver on the stairs repeats the same action. Next, the caregiver under the stairs grasps and lifts the leg gripping portion Ca , and further operates the leg movable gripping portion Cb that is slid and extended. Lift your limbs and back muscles up one step.

The caregiver who has reached the landing on the stairs shortens the lifting hand movable gripping part A3 by one step, further changes the gripping part to A2 and A1, pulls up the stretcher, and finally supports the pillow movable frame F3. Then, casters with brakes on the rear legs of the stretchers are landed on the landing on the stairs. At that time, the caregiver below the stairs slides the leg movable grip portion Cb to shorten the front leg and releases the brake of the caster with brake. The caregiver on the floor may move by moving the caster while supporting the pillow movable frame F3, and then move it on the floor as a four-wheeled wheelchair.

The reason why the suspension A4 can be fixed to the stretcher main body by the fixing screw on the side surface of the pillow is to stabilize the stretcher during the movement of the stairs. The caregiver's operation on the stairs lifts the stretcher too much
In order to break the balance of the stretcher and prevent it from falling forward,
This is because it is necessary not only to raise but also to suppress excessive rise.

  In the case of transfer on a flat surface or use in a wheelchair, the suspender A4 is rotationally housed on the back surface of the sheet S and fixed with a string or the like so as not to interfere with the stretcher operation.

The plurality of screw holes N1 of the slide tube having a child tube structure is for selecting an appropriate position of the movable gripper according to the height and body shape of the care recipient and the caregiver.

The caregiver slides the slide bar P in consideration of his / her height and adjusts the movable gripping part, and the caregiver is most effective in operating the stretcher up and down with the fixing screw N and the optional screw hole N1. The position where it is easy to put can be selected.

In accordance with the height of a main caregiver, put the main caregiver's head on the pillow by sliding the child tube type slide bar P pillow movable frame F3, pillow movable fixing screw N and the screw holes N1 of litter frame F The frame F3 is fixed.

In this example, a stair stretcher is used as a seat chair or a wheelchair in a room, a corridor, a road or the like using four casters of leg C. In this case, the caregiver took the care recipient like a sitting chair or a wheelchair, and when using it as a stretcher, it required two caregivers, but one caregiver grasped the pillow movable frame F3. It is possible to operate.

  By sliding and fixing the slide bar of the front leg frame C1, it can be used like a seat chair or a wheelchair reclining backward from a seat chair or a wheel chair. It can also be adjusted to the desired angle for reclining.

In this example, the caster T2 with a brake for the rear wheel is used to transfer the stretcher body in a room, a corridor, a road or the like while keeping the stretcher body substantially horizontal. In this case, the caregiver puts the care recipient from the seated state like a stretcher, and one caregiver holds the pillow movable frame F3 and floats the front wheel caster T2 with one brake. To operate the stretcher as a motorcycle .

  A care recipient who needs a stretcher cannot move by himself because his body is skeletally weak or unconscious. In such a case, when the transport is performed in a narrow passage or staircase in the house, the level of the stretcher may not be maintained at a normal length because the staircase is steep. If a stretcher cannot be used, it is not the case that it is not carried out by a method such as carrying it on the back, but if there is contracture on the body, it may not even be possible, and it may be injured by the care recipient. May impose risks.

Patient or the like as a principal caregiver, is hoping to safely move the stairs, such as day-to-day hospital and day care other than emergency. However, there are no stretchers that can be safely operated by a caregiver with a narrow staircase like a Japanese house, and there is no stretcher that can be safely transported to the care recipient, so it is actually going out even for hospitalization. is there.

  As a result of the increase in home care for the elderly, the need for care recipients and emergency patients who cannot move up the stairs on their own have increased in the narrow corridors and upstairs on the stairs. In Japan's residential environment, simple elevators cannot be installed on the stairs, and the risk of moving on the stairs will continue to increase.

  The stair stretcher of the present invention has been devised as a stretcher that can reduce the safety of stairs movement of a care recipient such as a patient and the labor burden of a caregiver responsible for transfer. This stair stretcher can be used not only on stairs but also as a sitting chair or reclining wheelchair, and it is equipped with a lift, slope, etc., and rides directly to a care vehicle equipped with a fixing device such as a wheelchair to go directly to the hospital. can do. This is a safe and comfortable transfer tool from the stairs to the vehicle for both the care recipient and the caregiver.
