Abstract

A bed sheet on the back of the body of a patient is easily changed. One side of the patient's body is slightly raised, the sheet is held between band-like plates constructed from rotatable rollers, the upper and lower pair of the plates is superposed on each other, and the upper and lower rollers rotate in the directions opposite to each other when the sheet is pulled. This moves the plates and the sheet between the patient and a mattress, enabling the used sheet to be removed. Then, a new sheet is held between the pulled-out plates, and the new sheet is pulled out from the opposite side. Thus, the bed sheet is easily changed. The roller plates (5, 6) are formed in a flexible band shape by connecting columnar pipes and the rotatable rollers together by connection links and connection pins. Each roller is formed of a hub having bearings at both ends. On a mattress (3) on which a sheet (2) where a patient lies on the back or on the front is laid down, and one or more sets of roller plates are used for a pair of upper and lower parts of the sheet. To change the sheet, the plates are inserted between the mattress and the sheet and between the sheet and the patient.

Problems to be solved by the invention

[0006] Until now, as described in the prior art, a special bed or a special processing was required for a bed replacement device, and it was not widely used. There is also a crane-type patient lifting device, but it is shunned that the device is heavily used for changing sheets. In many hospitals and nursing homes, the sheets are moved by half on the bed. Since this method moves the patient to one end in the long direction of the bed, there is a possibility that the patient may fall, and it is necessary to attach a fall prevention fence to the bed. In addition, the patient is reciprocated left and right, and the movement is large and time consuming. Moving the patient left and right also on the side of caring for the patient is hard work and contributes to low back pain and tendonitis. If staff at hospitals or nursing homes are vacant due to back pain or tendonitis, other staff will change more sheets, increasing the possibility of back pain or tendonitis, creating a vicious circle. When changing sheets is hard work, the patient also takes care of the caregiver, and the interval for requesting sheets changes becomes longer and the patient becomes unsanitary. The problem to be solved by the present invention is to provide a sheet replacement assisting device that is easy to operate and can be used at a low cost, eliminating the heavy labor and long time in sheet replacement and selecting a bed.

Means for solving the problem

[0007] In order to solve the above problems, it is difficult for the caregiver to lift the patient's body. It is difficult to lift the entire patient's body. However, it is not difficult for the patient's head and feet to float slightly, and the sheets on the patient's head and feet can be easily replaced. Therefore, how to replace the sheets on the patient's torso is an important part of the means to solve the problem. In the present invention, one plate is formed between a sheet and a mat, and one sheet is placed between a sheet and a patient. Insert the sheet a little and lift the patient's torso, lower the sheet, and bow the sheet from the opposite side of the plate. The roller pressed by the patient's torso's weight rotates and moves up and down between the patient and the mat. The plate moves in the direction the sheet is drawn. The plate moves and the end of the sheet As the plate passes between the body and the mat, the plate is stationary and the old sheets can be removed. When the new sheet is sandwiched between the plates while the plate is stationary and the sheet is pulled from the opposite side, the roller rotates and the plate moves in the opposite direction, and the new sheet passes between the patient and the mat and reaches any position. At that time, the sheet on the patient's torso can be replaced by removing the plate, and the sheets of the head and feet that have been folded and moved are stretched to spread the sheet over the entire mat and lay Is a solution.

The invention's effect

[0008] The present invention can also be used in mats and mattresses laid on a force floor whose main purpose is to be used in a bed, and many purchasing layers are expected, which can be provided at low cost due to mass production effects.

[0009] Since the present invention has a simple structure, it is possible to manufacture products with different specifications depending on the height and weight of the patient. Roller One width is shortened and two sets are used at a time. A device can be provided.

[0010] The size of a general patient according to the present invention is approximately 40cm in length and 70cm in width and 4cm in height, and is flexibly connected. Therefore, when folded, it can be held by an adult woman with one hand. Since it can be carried along with the sheets to be exchanged, it is easy to carry it for visiting care etc.

[0011] Large devices, such as lifting a patient, often fear the patient and the patient may reject the device. Since the present invention is small and used in the torso, it does not touch the patient's eyes and is difficult to be rejected.

[0012] The present invention is simple in structure and simple in operation, so that even when an elderly person is caring for an elderly person, work errors are unlikely to occur. But you can use it.

[0013] Sheet replacement according to the present invention enables sheet replacement even when the patient moves less and the bed width is narrow.

[0014] The sheet exchange in the present invention is such that the exchange plate reciprocates left and right under the patient's torso, and the old sheet can be removed and a new sheet can be laid in a single stroke, reducing the work time compared to the previous method. Can reduce the burden on patients and caregivers.

BEST MODE FOR CARRYING OUT THE INVENTION [0015] The best form is composed of mats, sheets and patients. Sheets are changed by only one caregiver. Next, one embodiment of the present invention will be described with reference to the drawings.

Example 1

[0016] FIG. 1 is a perspective view showing an outline of a sheet exchange auxiliary device, and shows the positional relationship of each component. The sheet exchanging device 1 of the present invention is used in a state where the patient 4 is laid on the back of the sheet 2 laid on the mat 3 along the longitudinal direction of the mat. Fig. 2 is a perspective view of the main configuration of the sheet changer. Sheet changer 1 Fig. 1 consists of a pair of upper roller plate 5 and lower roller plate 6 and is used with sheet 2 in between.

FIG. 3 is a perspective view of the upper roller plate 5 or the lower roller plate 6. The roller 8, the inner connecting link 7, and the outer connecting link 9 are connected by a connecting pin 10 to be bent. FIG. 4 is a cross-sectional view of the connecting portion. The roller 8 is constituted by a hub 18 having bearings 19 at both ends of a pipe 17 and is rotatable. Pass the shaft 16 through the bearing 19 of the roller 8, connect the inner connecting link 7 and the outer connecting link 9, and fix with the fixing clip 20 in a bendable state. The shaft 16 and the fixing clip 20 constitute the connecting pin 10 shown in FIG. FIG. 18 is a cross-sectional view of the roller portion, and a resin coating 18 is processed on the surface of the pipe 17 in order to reduce the burden on the patient. The hub 18 and the pin 16 can be freely rotated by a sliding bearing.

FIG. 5 is a perspective view of a sheet exchange setup, and FIG. 6 is a diagram showing a sheet exchange setup relationship.

The caregiver inserts one hand into the patient's torso 11, lifts one side slightly, inserts the lower mouth plate 6 from the bottom of the sheet 2, inserts the upper roller plate 5 from above the sheet 2, and pulls out one hand from the patient's torso 11. Lower the patient's monthly part 11 which was slightly buoyant. In FIG. 6, the mat 3 is a plane for convenience, but the upper roller one plate 5 and the lower roller plate 6 are actually submerged in the mat 3 in the portion where the load of the patient trunk 11 is applied. Since the amount of sinking of the mat 3 varies depending on the weight of the patient's monthly part 11 and the hardness of the mat 3, in this description, the mat 3 is assumed to be a plane in other drawings for convenience. In the state of Fig. 6, the caregiver moves to the opposite side where the upper roller plate 5 and the lower roller plate 6 are inserted, and lifts the patient's head 13 with one hand slightly, and the sheet with the other hand as shown in Fig. 5. Move in the direction of the arrow A. Similarly, lift the patient's foot 14 with a single hand and lift the sheet 2 in the direction of the arrow B in Figure 5 with the other hand. The state of Fig. 5 pulling around. With sheet 2 remaining on patient torso 11, sheet 2 on patient torso 11 is pulled to the left in FIG. 6 with both hands or one hand, and sheet 2 is pulled to the left in FIG. The roller 8 of the upper roller plate 5 and the lower roller plate 6 is pressed against the sheet 2 and the roller 8 of the upper roller plate 5 rotates to the right and the roller 8 of the lower roller plate 6 rotates to the left and the upper roller. Plate 5, lower roller plate 6 and sheet 2 move to the left and become the state shown in FIG.

[0019] FIG. 8 shows that the right end of the sheet 2 passes under the patient torso 11, and the weight of the torso 11 is not applied, and the rollers 8 of the upper roller plate 5 and the lower roller plate 6 are pressed against the sheet 2. The upper roller plate 5 and the lower roller plate 6 are stationary and the old sheet 2 can be removed. The new sheet 15 is inserted between the upper roller plate 5 and the lower roller plate 6 from the extracted direction, and the caregiver moves to the opposite side as shown in the setup perspective view when the new sheet is changed as shown in FIG.

[0020] In Fig. 9, the patient's head 13 Fig. 12 is slightly lifted with one hand, and the sheet 15 is moved with the other hand in the direction of the arrow C in Fig. 12. Similarly, the patient's foot 14 Fig. 12 is also with one hand. Lift the sheet a little and move the sheet 2 in the direction of the arrow D in Fig. 12 with the other hand and pull out the new sheet in Fig. 13 to get the perspective view.

[0021] In the rotational relationship diagram in the opposite direction of movement of the sheet exchange assisting device in Fig. 10, the patient head 13 that has been pulled forward and the patient foot 14 The sheet 15 in Fig. 13 is held with both hands and the sheet is pulled in the arrow direction E'F. 10 is pulled to the right in Fig. 10, the rollers 8 of the upper roller plate 5 and the lower roller plate 6 are pressed against the sheet 2 by the weight of the patient's torso 11, and the mouth of the upper roller plate 5

The first roller 8 rotates to the left and the roller 8 of the lower roller plate 6 rotates to the right, and the upper roller plate 5, the lower roller plate 6 and the sheet 2 move to the right.

[0022] In FIG. 11, the sheet 2 remains between the mat 3 and the patient 11 with the upper roller plate 5 and the lower roller plate 6 passing under the patient torso 11, and the upper roller plate 5 and the lower mouth plate. Remove plate 6, spread the sheet, fold the end into the mat, place a pillow on the patient's head, and complete the sheet exchange. If the end of the sheet 2 does not line up with the end of the mat 3, in Fig. 8, fold the end of the sheet 2 when inserting or insert the upper roller plate 5 and the lower roller plate. Insert sheet with seat 6 slightly back. In this explanation, the device reciprocates in the opposite direction, but the sheets can be exchanged in one direction by continuing the old and new sheets.

[0023] In the case of a large patient, use two sets of sheet replacement aids for the torso or a long roller. Use a roller plate whose outer diameter has been changed according to the hardness of the mat. Since the sheet changing auxiliary device rotates the roller, a long string or the like may be caught, and a cap is required for use on the head.

[0024] Fig. 15 is a sheet exchange auxiliary device composed of a roller plate 21 divided for carrying. Usually, the upper and lower roller plates can be bent and can be folded and carried, but further, the pin of the connecting portion is removed. It can be divided into smaller sizes for convenient carrying, and when the roller plate is not long enough, the length can be adjusted by adding unused blocks.

FIG. 16 shows a bed in which sheets can be exchanged at all times as a bed 23 with a sheet exchange auxiliary device as a bed having a storage space 22 by fixing the sheet exchange auxiliary device to the bed.

[0026] Fig. 17 shows a sheet change assisting device sheet 27 intended for use in a sheet change assisting device with a handle 24 for easy caregiver pulling, and the sheets and sheets are fastened to the fastener 25 or hook. Some sheets can be divided into a plurality of sheets with a tape having an uneven surface and can be joined to other sheets, and others have a special number that has a puller part that reinforces the part that the device contacts.

[0027] Fig. 19 shows a state in which the lower roller plate 6 of the sheet exchange auxiliary device is bent downward at the end (mat end) 29 of the bed when the bed width is narrow, and the resistance and the bent portion of the bent portion are bent. The lower roller plate 6 may move along the patient's torso due to the weight of the sheet, and the sheet exchange assist device may not function. In this case, it is desirable that a plate-like object is laid under the lower roller plate 6 or the connecting link portion is fixed or semi-fixed so as not to be bent downward. Fig. 20 shows the lower roller plate 6 with the fixed link link fixed, and the roller 8 connected by the fixing link 30.The fixing link 30 is straight or arcuate, but inside the patient's month Because it does not bend, the burden on the patient increases. Figure 21 shows the shape of a semi-fixed connecting link, with semi-fixed outer link protrusion 31 and semi-fixed inner link recess 32, with semi-fixed outer link stopper 33. With a semi-fixed inner link claw 34 Any combination of 34 allows the patient's torso to bend inward without bending the lower roller plate downward. The shape of the lower roller link by the semi-fixed connecting link is the same as that shown in Fig. 3.

[0028] Fig. 22 shows a roller 35 having a hub on one side connected by an inner connecting link 36. When the width between rollers is narrow or the pipe is long, the roller interferes. There is a possibility that the purpose cannot be achieved. The outer wheel 37 in FIG. 23 is an outer wheel 37 that has a roller 35 (FIG. 22) with a hub on one side shortened and is attached to the outside of a normal connecting link 38, and is effective in preventing the link portion and the sheet from being caught. Become. In Figure 23

The outer wheel 37 is attached to the tip link, but it is possible to attach it to all the links because of cost, link shape, etc. In addition, when longer rollers are required, it is possible to provide inner connecting links 36 shaped as shown in Fig. 22 between the links on both ends, but use two sets of normal upper and lower roller plates. Is easier to handle.

[0029] FIG. 24 shows a pet sheet exchange assisting device 40. When the pet 39 is obsessed with obesity or aging and the driving ability is reduced and the pet sheet 41 is laid on the floor 42, the pet sheet is replaced. When it is necessary to replace the pet sheet 41 and the like, the replacement operation is performed in the same procedure as a human by using the pet sheet replacement auxiliary device 40.
