Description

  The present invention relates to an air cell control device for controlling an air cell placed on a base of a bed apparatus.

  Various proposals have been made on mattresses to improve the comfort and safety of users. For example, in the mattress described in Patent Document 1, it is possible to lift up a part of the body with a small volume without deteriorating sleeping comfort by inserting airbags that support the back and waist between the upper and lower air cells of the mattress.

  Moreover, in the mattress described in Patent Document 2, the mattress is divided into a plurality of air cell groups in the longitudinal direction, and the pressure on the back and thighs is increased, thereby stably supporting the human buttocks and increasing the thickness of the mattress. It is assumed that body pressure can be dispersed efficiently while suppressing.

Japanese Patent Laid-Open No. 2007-082861 JP 2011-160892 A

  The thicker the mattress is, the more the user can be depressed, and the contact area between the mattress and the body can be increased to reduce the pressure applied to the body.

  However, when the thickness of the mattress is increased, the relative height of the bed fence with respect to the mattress is lost, and there is a problem that the risk of falling over the fence (side rail) on the side of the bed increases.

  Moreover, in the mattress described in Patent Document 1, there is a problem that the size of the airbag does not fit due to the physique of the bed user when the airbag is put under the back or waist.

  In the mattress described in Patent Document 2, by increasing the pressure of the back and thighs, it is possible to keep the buttocks at a low pressure while suppressing the thickness of the mattress and increase the contact area, but the contact area mainly in the longitudinal direction of the mattress However, there was a problem that the contact area in the short direction and the sense of stability could not be increased.

  In order to prevent the patient from falling and to stabilize the posture, a method of arranging a support member on the mattress can be considered. However, the bed apparatus performs various operations such as a back raising operation, a knee raising operation, and a leg lowering operation, and support is not always necessary.

  Specifically, the patient may be misaligned during use, may be used for positioning (inserting a pillow between the patient's body and mat), may not be able to perform the same positioning every time, The problem of not becoming occurred. Further, when a patient is supported using a pillow, there are problems that the number of pillows is insufficient for the patient, and that the pillow is bulky, so that it is difficult to secure a storage place when not in use.

  Next, an embodiment to which the air cell control device of the present invention is applied will be described. In this embodiment, the bed device 1 including the air cell control device will be described as an example.

[1. overall structure]
The overall configuration of the bed apparatus 1 in the present embodiment will be described with reference to FIGS. 1 and 2. FIG. 1 is a view of the bed apparatus 1 as viewed from above. FIG. 2 is a diagram illustrating the bed apparatus 1 from the front side on the foot side (air cell control apparatus 20 side in FIG. 1).

  In the bed apparatus 1, the mat body 7 is placed on the base 5. Here, the mat body 7 includes a plurality of main cells 12 using air cells arranged continuously in the longitudinal direction. The mat body 7 is configured by being covered with a cover.

  A support cell 10 that is an air cell for supporting the patient P is provided between the mat body 7 and the base 5. The body of the patient P is supported by the support cell 10.

  Here, the bed apparatus 1 is used such that the foot side of the patient P is in the F direction in FIG. 1 and the head side is in the H direction in FIG. Therefore, the right side of the patient is the R direction in FIG. 1, and the left side is the L direction in FIG.

  The support cell 10 is composed of a support cell 10R on the right side and a support cell 10L on the left side.

  A blower tube is connected to each air cell (support cell 10, main cell 12) from the air cell control device 20. For example, the air cell control device 20 and the support cell 10 are connected by the blower tube 16, and air is supplied and exhausted from a pump provided in the air cell control device 20. Moreover, the main cell 12 is divided into several cell groups, and each is connected by the air cell control apparatus 20 and the ventilation tube (not shown).

  The base 5 of the bed apparatus 1 is divided into a plurality of bases, and can perform operations such as a back raising operation, a knee raising operation, and a leg lowering operation, for example. FIG. 3 is a schematic diagram for explaining the operation. The base is divided into a base 5a (back bottom), a base 5b (waist bottom), a base 5c (knee bottom), and a base 5d (foot bottom), and the base 5a, the base 5c, and the base 5d are configured to be rotatable. ing.

  Here, in the present embodiment, the angle α at which the base 5a (back bottom) moves is referred to as a back raising angle, and the angle β at which the base 5c (knee bottom) moves is referred to as a knee raising angle. Since FIG. 3 is a schematic diagram, for example, the base may be further divided.

  Further, the mat body 7, the support cell 10, and the air cell control device 20 may be integrally formed as a mattress device. In this case, the mattress device is placed on the base 5. Note that the air cell control device 20 may be configured to be connected to the outside via, for example, a supply / exhaust pipe, instead of being integrally formed.

[2. Functional configuration]
Next, the functional configuration of the bed apparatus 1 including the air cell control device 20 will be described. As shown in FIG. 4, the bed apparatus 1 includes a control unit 100, a support cell control unit 110, a main cell control unit 120, a storage unit 130, a pump unit 140, a bed driving unit 145, and bed information acquisition. Unit 150, patient information acquisition unit 160, environment information acquisition unit 170, operation unit 180, and notification unit 190.

  The control unit 100 is a functional unit for controlling the entire bed apparatus 1. The control unit 100 implements various functions by reading and executing various programs stored in the storage unit 130, and is configured by, for example, a CPU (Central Process Unit).

  The support cell control unit 110 is a functional unit for controlling and adjusting the internal pressure of the support cell 10. In order to supply / exhaust the support cell 10, the pump unit 140 is controlled. The main cell control unit 120 is a functional unit for controlling and adjusting the internal pressure of the main cell 12. In order to supply and exhaust air to each main cell 12, the pump unit 140 is controlled. The pump unit 140 is connected to the support cell 10 and the main cell 12 by a blower tube. When the pump unit 140 is operated, air is supplied to and exhausted from the support cell 10 and the main cell 12. Thereby, the internal pressure of the air cell (support cell 10, main cell 12) is adjusted.

  The storage unit 130 is a functional unit that stores various programs necessary for the operation of the bed apparatus 1 and various data. The storage unit 130 includes, for example, a semiconductor memory, an HDD (Hard Disk Drive), or the like.

  The storage unit 130 stores support cell pressure information 132, bed information 134, patient information 136, and environmental information 138. Each information stores values acquired by other functional units and preset values set in advance.

  For example, the support cell pressure information 132 stores an internal pressure value when the support cell 10 increases the internal pressure to support the patient. When the patient is supported, the support cell control unit 110 adjusts the internal pressure to the set pressure set in the support cell pressure information. For example, as the set pressure, “4 kPa” is set as the left and right support cells. Note that one set pressure may be stored for the left and right support cells as the same value, or different values may be used for the left and right. Further, in the case of a configuration having a plurality of support cells, the set pressure for each support cell may be stored.

  The bed driving unit 145 is a driving device and a control device for performing the back raising operation, the knee raising operation, the leg lowering operation, and the height (high / low operation) of the bed device for the bed device 1. For example, a back-up operation is realized by using an actuator and driving the actuator.

  The bed information acquisition unit 150 is a functional unit for acquiring the current bed state and outputting the acquired value as bed information 134 to the storage unit 130. Here, as the bed information 134, in the present embodiment, the back raising angle, the knee raising angle, the bed height, and the like of the bed are acquired.

  The patient information acquisition unit 160 is a functional unit for acquiring information about a patient and outputting the acquired state to the storage unit 130 as patient information 136. Here, in this embodiment, patient contracture information, patient posture, patient center of gravity, patient sleep state, and the like are acquired as patient information 136.

  The environment information acquisition unit 170 is a functional unit for acquiring an environment in which the bed apparatus 1 is present and outputting the acquired environment to the storage unit 130 as environment information 138. Here, as the environment information 138, in this embodiment, the illuminance of the room, the temperature of the room, and the like are acquired.

  The operation unit 180 is a functional unit for a user such as a patient or an assistant, a nurse, and a doctor to give an input instruction to perform a predetermined operation. For example, it is configured by a remote control device using a hardware key or a software key, an operation panel provided in the bed device 1, or another terminal such as a smartphone. By operating the operation unit 180, the back raising operation and the knee raising operation of the bed apparatus 1 can be performed, the internal pressure of the cell can be adjusted, and the set pressure can be set.

  The notification unit 190 is a functional unit for performing various notifications by the user. For example, various notification devices such as a liquid crystal display indicating a state, a buzzer for indicating the position of a patient, and a lamp are assumed.

[3. Processing example]
Then, the process example of the bed apparatus 1 in this embodiment is demonstrated.

[3.1 First Processing Example]
First, the first processing example will be described. The first processing example realizes processing for increasing the internal pressure by supplying air to the support cell 10 or decreasing the internal pressure by exhausting from the support cell 10 according to the back raising operation of the bed apparatus 1. .

[3.1.1 Processing when raising the back]
First, the process when raising the back will be described with reference to FIG. When a back raising operation is detected from the operation unit 180 (step S102), it is confirmed whether or not the back raising angle has fluctuated more than a threshold value (step S104). Accordingly, for example, if it is possible to instruct the patient without using the support cell 10, it is possible to realize that no air is supplied to the support cell.

  When the back raising angle fluctuates by more than the threshold value (that is, when the back raising bottom of the predetermined threshold value or more rises here) (step S104; Yes), the air supply control of the support cells 10 on both sides is performed (step S106). Then, when the internal pressure of the support cell 10 becomes a predetermined set pressure (step S108; Yes), the supply of the support cells 10 on both sides is stopped (step S110).

  And the back raising angle after back raising operation | movement is acquired (step S112), and the main cell control part 120 performs control of the main cell according to a back raising angle (step S114). For example, when the back raising angle is large (when the back raising is frequently performed), the bottom of the patient is prevented by increasing the internal pressure of the main cell in the buttocks.

  In this process, the back-up operation and the air supply control of the support cell are operated in parallel, but the back-up operation is performed after the support cell is supplied first or the back-up operation is completed. It is good also as starting supply of a support cell later. In other words, the back raising operation may be stopped in step S106, and the back raising operation may be resumed after step S110 is completed.

  In addition, a process of changing the speed of the back raising operation may be performed when supplying the support cell. For example, when the air supply control of the support cell is performed in step S <b> 106, it is possible to perform a process of slowing down the back raising operation.

  Further, the main cell control in step S114 is also executed after the back raising operation in step S112 in FIG. 5, but may be performed together with the back raising operation, for example.

  In the processing example described above, for example, when the support cell 10 is used immediately during the back raising operation, the threshold value in step S104 may be set to “0”.

[3.1.2 Processing when lowering back]
Next, processing during the back-lowering operation will be described. When a back-lowering operation is detected from the operation unit 180 (step S152), it is confirmed whether or not the back raising angle has fluctuated more than a threshold value (step S154).

  When the back raising angle fluctuates by more than a threshold value (that is, here when the back raising bottom is lowered by a predetermined threshold value or more) (step S154; Yes), the exhaust control of the support cells 10 on both sides is performed (step S156). Then, when the internal pressure of the support cell 10 becomes the set pressure (step S158; Yes), exhaust of the support cells 10 on both sides is stopped (step S160). Here, the back raising angle after the end of the back-lowering operation is acquired (step S162). Then, main cell control corresponding to the back raising angle is performed (step S164).

  As a specific example, for example, when the base 5 is flattened (back raising angle is “0” degree), the process of setting the internal pressure of the support cell 10 to “0” is executed.

  As described in [3.1.1], the back-lowering operation and the support cell operation may be executed in parallel or sequentially. Further, processing such as changing the operation speed of the back-lowering operation may be performed. These operations may be selectable by the user.

[3.2 Second Processing Example]
Next, the second processing example will be described. In the second processing example, according to the knee lifting operation of the bed apparatus 1, the internal pressure is lowered by exhausting from the support cell 10 to eliminate the feeling of pressure, or the internal pressure is increased by supplying air to the support cell 10. To achieve the process.

[3.2.1 Knee-up process]
First, processing during the knee-lifting operation will be described with reference to FIG. When the knee-lifting motion is detected from the operation unit 180 (step S202), it is confirmed whether or not the knee-lifting angle has fluctuated more than a threshold value (step S204).

  When the knee-up angle fluctuates by more than a threshold value (that is, here when the knee bottom of a predetermined threshold value or more has risen) (step S204; Yes), supply / exhaust control of the support cells 10 on both sides is performed (step S206). Here, when the internal pressure of the support cell becomes the set pressure (step S208; Yes), supply / exhaust of the support cells on both sides is stopped (step S210), and the current knee-up angle is acquired (step S212). Then, control of the main cell is executed according to the state of the patient P at this time (step S214).

  In this process, the knee-lifting operation and the support cell supply / exhaust control are operating in parallel. However, the knee-lifting operation or the back-lifting operation is completed after the support cell supply / exhaust is completed first. It is good also as starting supply of a support cell later. In other words, the knee raising operation may be stopped in step S206, and the knee raising operation may be resumed after step S210 is completed.

  Further, a process of changing the speed of the knee-lifting operation may be performed during supply / exhaust of the support cell. For example, when the support cell supply / exhaust control is performed in step S206, it is also possible to perform a process of slowing down the knee-lifting operation.

  Further, the main cell control in step S214 is also executed after the knee-lifting operation in step S212 in FIG. 7, but it may be performed at the time of the knee-lifting operation, for example.

  In the processing example described above, for example, when the support cell 10 is used immediately during the knee-lifting operation, the threshold value in step S204 may be set to “0”.

[3.2.2 Treatment at knee lowering]
Next, processing during the knee lowering operation will be described with reference to FIG. When the knee-lowering motion is detected from the operation unit 180 (step S252), it is confirmed whether or not the knee-up angle has fluctuated more than a threshold value (step S254).

  When the knee-up angle fluctuates by more than a threshold value (that is, when the knee bottom descends by more than a predetermined threshold value here) (step S254; Yes), the support cell supply / exhaust control is performed (step S256). Then, when the internal pressure of the support cell 10 becomes the set pressure (step S258; Yes), the supply / exhaust of the support cell 10 is stopped (step S260). Then, main cell control corresponding to the knee lift angle is performed (step S264).

  As described in [3.1.1], the back-lowering operation and the support cell operation may be executed in parallel or sequentially. Further, processing such as changing the operation speed of the back-lowering operation may be performed. These operations may be selectable by the user.

[3.3 Third Processing Example]
Next, a third processing example will be described with reference to FIG. The third processing example realizes processing for adjusting the internal pressure of the support cell 10 in accordance with the height (high / low) of the bed apparatus 1.

  First, the bed height is input from the operation unit 180 (step S302). Then, when the height of the bed apparatus 1 changes (step S304; Yes), exhaust control of the support cells 10 on both sides is performed (step S306). Here, when the internal pressure of the support cell 10 becomes the set pressure (step S308; Yes), exhaust of the support cells 10 on both sides is stopped (step S310).

  Thereafter, the bed state is acquired (step S312), and the internal pressure of the main cell 12 is controlled according to the bed state (step S314). Specifically, when the patient moves at a stage where the bed height changes or the center of gravity changes, control is performed to adjust the internal pressure of the main cell 12 so as to be in a state suitable for the patient.

  An example of the third processing example will be described. For example, when the bed height is increased so that nurses, doctors, assistants, etc. can easily change the patient's position, change diapers, treat, etc., the exhaust of the support cell 10 has priority over the other main cells 12. To do. Thereby, since the bed becomes flat more quickly, a bed device that is easy to use for nurses, doctors, assistants, and the like can be provided.

  Moreover, when a patient lowers the height of a bed to transfer to a wheelchair or the like, the support cell 10 can be preferentially exhausted to provide an environment in which the patient can easily transfer. Further, in this case, control may be performed such that only the support cell 10 on the side of transfer (for example, the side where the wheelchair is placed) is exhausted. Specifically, when transferring from the right side of the bed apparatus 1 (patient), the support cell 10L may be left as it is, and control may be performed to exhaust only the support cell 10R.

  In addition, although the 3rd processing example mentioned above demonstrated the state in which the bed apparatus 1 was already supplying air to the support cell 10 in the normal state (before the processing of the 3rd processing example), for example, the height of the bed apparatus 1 is increased. When it is lowered, it may be operated so as to be supplied in reverse (FIG. 10). Air is supplied to the support cell 10 in step S352 of FIG. 10, and air supply to the support cell 10 is stopped in step S354. When the patient sits on the end of the bed apparatus 1 (mat body 7) at the time of transfer, a part of the main cell 12 bottoms out. By slightly increasing the internal pressure of the support cell 10, it is possible to prevent bottoming even if the patient sits on the end of the bed apparatus 1.

[3.4 Fourth Processing Example]
Subsequently, a fourth processing example will be described. The fourth processing example measures body pressure in the bed apparatus 1 (mat body 7), which is one of patient information, and performs processing based on body pressure.

[3.4.1 Support cell control according to patient posture]
Processing for controlling the support cell 10 according to the posture of the patient P will be described with reference to FIG. First, the body pressure of the patient P is measured by the body pressure sensor (step S402). By measuring the body pressure, the posture of the patient P can be determined (step S404). When the posture of the patient P is biased (step S406; Yes), the support cell 10 is controlled (that is, the supply and exhaust of the left and right support cells 10L / 10R are performed).

  Specifically, for example, the internal pressure of the support cell 10L / 10R is adjusted while determining the body pressure value so that the body pressure value is equal to or less than a predetermined threshold value, and control is performed so that the posture of the patient P becomes appropriate. Further, when the patient P is biased due to hemiplegia or lower limb contracture, the support cell 10 on the side where the body pressure is concentrated is supplied and inflated to increase the contact area. Reduce body pressure value.

[3.4.2 Patient presence or absence of contracture]
Next, a processing example for controlling the support cell 10 based on the contracture information of the patient stored in the patient information 136 will be described with reference to FIG. First, the body pressure of the patient P is measured by the body pressure sensor (step S452). The posture of the patient P is determined based on the measured body pressure (step S454).

  Here, when the contracture information of the patient P is included (stored) in the patient information 136 (step S456; Yes), the set pressure of the left and right support cells is determined according to the posture of the patient. (Step S458). And the support cell 10 is controlled so that it may become the set pressure determined (step S460).

  Specifically, based on the contracture information, the support cell 10 on the side where the posture of the patient is biased and concentrated is inflated. Thereby, the contact area of a patient and a cell can be increased and a body pressure value can be reduced.

[3.5 Fifth Processing Example]
Subsequently, a fifth processing example will be described with reference to FIG. The fifth processing example is executed in combination with the above-described processing examples, or is executed alone.

  First, the state of the patient P is acquired (step S502). Then, the posture (position) of the patient P is determined (step S504), and it is determined whether or not the position of the patient P is on the support cell (step S506).

  When the position of the patient P is on the support cell 10 (step S506; Yes), a process of suppressing the supply of the support cell on the side where the patient is present is executed (step S508). That is, when the patient is sleeping in front of the support cell, it is possible to realize a process in which the support cell on the side on which the patient is riding is not inflated to prevent falling.

  In step S508, in addition to suppressing the supply of air, the notification unit 190 may perform a notification operation. By performing the notification operation, a nurse, a doctor, an assistant, or the like can change the posture of the patient P or shift the position.

[3.6 Sixth Processing Example]
Subsequently, a sixth processing example will be described with reference to FIG. The sixth processing example is processing for controlling the support cell 10 based on the sleep state of the patient P.

  First, body pressure is measured by a body pressure sensor (step S602). Here, it is determined whether or not the patient P is in a sleep state based on the movement of the body pressure (step S604). When it is determined that the patient is sleeping (step S606; Yes), the support cell 10 is controlled. For example, the air is supplied during sleep, and falls during sleep are prevented. Then, the main cell 12 is controlled according to the patient's condition (step S610).

  In the above processing example, it is determined by the body pressure sensor whether or not the patient P is in a sleep state, but other means may be used. For example, it is good also as determining whether it is in a sleep state by the environment information 138 (for example, illumination intensity etc.) acquired by the environment information acquisition part 170. FIG.

  Moreover, in the above-described processing example, the case of the sleep state is determined. However, for example, a process of performing exhaust control from the support cell 10 when transitioning to the awake state is also possible.

[4. Application example]
Of course, the processing examples described above can be operated in combination. For example, the first processing example is used during the back raising operation, and the second processing example is executed during the knee raising operation. Then, when raising the back, it is possible to execute the fourth embodiment based on the posture of the patient.

  Further, the support cell control unit 110 and the main cell control unit 120 can be operated in cooperation. That is, by adjusting the internal pressure of the main cell 12 based on the internal pressure of the support cell 10, it is possible to provide a bed apparatus that is comfortable for the patient.

Moreover, you may perform alerting | reporting operation | movement by the alerting | reporting part 190 according to the internal pressure of the support cell 10. FIG. For example, when the patient P is biased, there is a risk of falling (the internal pressure of one support cell 10L (10R) is higher than that of the other support cell 10R (10L)). Can also be done.

[5. Modified example]
The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and the design and the like within the scope of the present invention are also within the scope of the claims. include.

  Moreover, although the above-mentioned embodiment is collectively described for convenience of explanation, it is needless to say that the configuration requirements can be selected as necessary. For example, in the first processing example, when providing a bed apparatus that controls the support cell 10 in cooperation with the back raising operation, the patient information acquisition unit 160 and the environment information acquisition unit 170 are not necessary, and the patient information 136, the environment Information 138 need not be stored.

  Moreover, the air cell control apparatus of this invention should just be able to control the support cell 10 and the main cell 12. FIG. In other words, each functional unit does not need to be directly provided, but may be connected to an external device and controlled. That is, the processing example described may be realized by a program. The program may be executed by another device, or may be realized by, for example, a mobile terminal connected wirelessly or a smartphone.

  In the above-described embodiment, the mat body is also described as constituting the air mattress, but the mat body may be composed of other materials. That is, the mat body may be constituted by a spring mattress, a urethane mattress, a polyester fiber mattress, a palm mattress, or the like.
