FIG. 1 shows an outline of the air bag of the present invention and the main device 20 for manic exhausting the air. Four air bags are attached to the substrate sheet 10, and each air bag is connected to the air valve chamber 30 of the main device 20 via the air supply / exhaust pipes 21, 22, 23, 24. Air is sent and exhausted to each air bag via a main device 20 that controls air supply and exhaust. The postural change device shown in FIG. 1 can inject air into an air bag and utilize the force of the air bag to inflate to "raise the back", "raise the knee", and "turn over" of a bedridden care recipient. The air bag is preferably made of resin or cloth coated with resin.

The air bag for "raising the back", "raising the knee", and "turning over" is connected to the air valve chamber 30 of the main device 20 by air supply / exhaust pipes 21, 22, 23, 24, respectively. The air compressed by the air supply pump 26 in the main device is sent from the air supply port 37 of the air valve chamber to the air valve chamber 30, and from there, the air supply / exhaust pipes 21 and 22 are sent through the air valves 31, 32, 33 and 34. , 23, 24. The air sent to the air bag is discharged by the exhaust pump 27 after a predetermined operation. These sending and discharging operations can be operated by the main device 20 or the remote controller 40, and can be operated by either the caregiver or the bedridden care recipient.

FIG. 2 shows the appearance of the main device 20 and the remote controller 40. Operation buttons are arranged in both cases, and by operating the buttons, the operation described later is made to be an air bag to change the position of the care recipient.

The mechanism of the air sent to the air bag and the exhaust air will be described with reference to FIG. The posture changing device includes a control device 28, an air supply pump, 26, an exhaust pump 27, and an air control unit 30. Air is sent from the air supply port 37 of the air control unit 30 to the back-raising bag 11, the right air bag 12, the left air bag 13, and the knee-raising air bag 14 to which the base sheet described later is mounted. , 24.

Air supply, exhaust, and stop of operation are operated by the main device of FIG. 2 or the switch of the remote controller. The air pressure sensor 36 is provided in the air control unit 30, and automatically stops the air supply based on the signal from the air pressure sensor 36 in order to prevent the bag from bursting due to excessive air supply.

The air supply / exhaust ports of the air control unit 30 connected to each air pack are provided with air valves 31, 32, 33, 34 capable of stopping the flow of air. Further, a fifth air valve 35, which is an exhaust opening / closing valve, is installed at the exhaust port 39 of the air valve chamber 30, and has a structure capable of controlling the inflow and outflow of air by the exhaust pump 27.

An air bag that changes the position will be described with reference to FIG. The thickness of the substrate sheet to which the air bag is attached as shown in FIG. 4 is extremely thin and integrated, and since it can be folded, it can be easily moved and installed.

The air bags attached to the substrate sheet 10 include a main back-raising air bag 11, a right sub-back-raising air bag 112, a left sub-back-raising air bag 113, and a right air bag for changing the left and right positions. It is composed of 12, a left air bag 13, and a knee-raising air bag 14.

The main back-raising air bag 11 is attached to the back of the base sheet, and is opened to the two right sub-back raising air bags 112 and the left sub-back raising air bag 113 and the base sheet attached to the front surface of the base sheet. Air enters and exits through the ventilation holes. Therefore, as the air enters and exits the main back-raising air bag, the air flows in and out of the sub-back-raising air bag in the same manner. When air is sent to the main back-raising air bag and the care-requiring person's back-raising starts, air is also sent to the two sub-back-raising air bags 112 and 113 and the left and right of the care-requiring person raised by inflating. Can be supported from both sides.

If you want to inflate the back-raising air bag, follow the procedure below. When the "back-raising" switch on the remote controller or the main body of the control device is pressed, the air supply pump 26 is activated to send out air.
At this time, since VALVE-2, 3, 4, and 5 in FIG. 3 are in the closed state and only VALVE-1 is in the open state, the compressed air flows through the air supply / exhaust pipe 21 and flows into the back-raised air bag. The air bag is inflated, and the air bag that raises the main back lifts the back of the care recipient by the force of the inflated air pressure, and the left and right secondary back raising air bags 112 and 113 stabilize the left and right of the care recipient. When the care recipient presses the stop switch at an appropriate position, the VALVE-1 is closed, the air sent out is trapped, and the air bag is stabilized. If the stop switch is not pressed, the back-raising air bag 11 inflates to the maximum size, but the air supply pump 26 automatically stops from 28 to the control device of the main device in response to the signal from the air pressure detection sensor 36.

To remove the compressed air from the back-raising air bag 11 to shrink it and return it from the back-raising state to the original sleeping state, the following operation is performed. When the lower switch of the remote controller or the control device main body is pressed, the VALVE-1 (first air valve 31) and VALVE-5 (fifth air valve 35) of the air valve chamber 30 are opened and the air is released from the exhaust port 39. Alternatively, the air bag 11 is returned to the original flat sheet state by pulling out to the exhaust pump 27 and raising the back.

When using "turning over air bag left and right" and "knee raising air bag", the air valve that is not used is closed and the air valve that is used is opened. Here, due to the structure of the seat with the air bag on the front and back and the physical structure of the care recipient, "back raising" and "knee raising" can be performed at the same time, but "back raising" and "back raising" and " The structure is such that the "turning over" operation cannot be performed at the same time.

FIG. 5A shows a state in which the care-requiring person stands up with the air bag inflated. The main back-raising air bag 11 is attached to the back surface of the base sheet 10, and the weight of the body on the base sheet 10 suppresses the movement during expansion. On the other hand, the sub-back-raising air bags 112 and 113 are attached to the surface of the seat, and the main back-raising air bags 11 and the sub-back-raising air bags 112 and 113 allow air to enter and exit through the seat. When air is inserted into the main back-raising air bag 11, the sub-back-raising air bags 112 and 113 also inflate at the same time. The sub-back-raising air bags 112 and 113 prevent the body of the care recipient from shifting sideways when the main back-raising air bag 11 is inflated.

FIG. 5B shows a state in which the knee portion of the care recipient is lifted when the knee is raised. You can select from two types of air bag operation, manual and automatic. When the knee-raising button of the main device 20 or the remote controller 40 is operated, the air supply pump 26 operates to supply air. The VALVE-4 (fourth air valve 34) is opened, the air valves other than the air valve VALVE-4 are closed, and air is sent to the knee-raising air bag. The maximum pressure is detected and limited by the air pressure detection sensor 36. When the bulge of the knee-raising air bag 14 is exhausted, the knee-lowering button of the main device 20 or the remote controller 40 is operated, and the air is exhausted from the exhaust port 39 of the air valve chamber 30 to the outside air or to the exhaust pump 27.

FIG. 5C shows a state of turning over air bag. There are three types of care-requiring states: supine (supine position), leftward (left lateral decubitus position), and rightward (right lateral decubitus position). It can be repeated by selecting either 90 minutes or 120 minutes. This time interval is "basically recommended to be repositioned within 2 hours" in the repositioning guidelines for pressure ulcer prevention. The 2009 NPUAP / EPUAP Joint Guidelines also state that "the frequency of postural changes is determined by the assessment of the patient's tissue endurance and activity level, general condition, healing objectives, and skin condition." It is possible to set according to the situation according to the guideline.

To inflate the roll-over air bag, follow the procedure below. When you press the "automatic turnover" switch on the remote controller or the control device, the auto time function in the control circuit is activated, and the air pump on the left side is activated to inflate the air bag on the left side when viewed from the care recipient. Inflate the air bag by sending air to the turning air bag (left air bag 13). When the left air bag is inflated to the maximum, the care recipient's body leans to the right and is in a stable right lateral decubitus position. After a certain period of time, the air in the left air bag that had been inflated is discharged and the sheet returns to its original flat state.

After a certain period of time, the right air bag (right air bag 12) swells to the maximum, and the care recipient's body leans to the left and becomes stable (left lateral decubitus position). After a certain period of time, the inflated air in the air bag on the right side is discharged and the sheet returns to its original flat state. After that, this operation can be automatically repeated by setting the microcomputer to prevent bedsores of the care recipient. This repetition time can be selected from 60 minutes, 90 minutes, and 120 minutes according to the physical condition of the care recipient. In addition, it is possible to turn over manually so that it can be used for changing diapers. The development point here is the fulcrum of the body when the care recipient turns over. As shown in FIG. 5C, the swelling air bag can be reliably lifted and rotated because its bottom surface is attached to the substrate sheet 10 up to the turning rotation fulcrum.

The process of automatically switching the left and right air bags to change the position will be described with reference to FIG. It should be noted that the timer operation, each air valve, the air pump, and the exhaust pump can be controlled by well-known hardware or software such as a microcomputer.
