Description

  The present invention relates to a bed system, for example, a bed system for a person who has been in bed for a long time, such as a sick person.

  Conventionally, as a bed, there is a nursing bed described in JP-A-2003-52762 (Patent Document 1). The nursing bed (hereinafter simply referred to as a bed) includes a backrest plate that supports the upper body of the person, and the backrest plate is rotatable with respect to the bed frame. In this bed, a person can raise only the upper body by rotating the backrest plate with respect to the bed frame.

  Since the conventional bed can raise only the upper body, the person can get off the bed more smoothly. However, in the case of a person who has been lying on the bed for a long time due to care or hospitalization, etc., because the muscle strength etc. is weak, the above conventional bed, that is, the upper body can be raised, and the person can descend smoothly from the bed. Even if you are using a bed that makes it possible, people may fall, slip off or fall from the bed. And even now that beds that can raise the upper body of people are widespread, one of the main causes of broken bones is actually falling or falling from the bed.

JP 2003-52762 A (FIG. 1)

  On the other hand, the inventor of the present application invented a bed that can stand up to a position close to a posture in which a person stands up, in which the entire human body mounting surface in the bed can be tilted with respect to a horizontal plane (this The invention is not known at the time of filing this application). Here, since this bed can stand up to the position close to the posture where a person stands up, the person can be greatly prevented from falling or falling.

  However, with this bed configuration, the posture of a person greatly fluctuates from a sleeping posture to a posture that is close to a standing posture. Etc. may occur.

  On the other hand, it is known that a person lying on a bed for a long period of time, such as an inpatient, has a small change in body position and a pressure ulcer (bed slip). Therefore, in hospitals, etc., in order to prevent pressure ulcers, there is a need for nurses to change their patient's sleeping posture on a regular basis, which is a big burden on nurses, etc. is there.

  Therefore, an object of the present invention is to provide a bed system that can adjust the compression force of the mat based on blood pressure, and can achieve at least one of preventing a large increase in blood pressure and suppressing the occurrence of pressure ulcers. It is in.

In order to solve the above problems, the bed system of the present invention is:
A bag-like mat filled with fluid;
A detection device for detecting at least one of a blood pressure value and an elapsed time;
A pressure adjusting device that adjusts the pressure of the fluid in the mat based on at least one of the blood pressure value and the elapsed time.

  In the present invention, when the detection device capable of detecting the blood pressure value and the pressure adjusting device for adjusting the pressure of the fluid in the mat based on the blood pressure value, the pressure of the mat fluid is changed when the blood pressure changes. Yes, you can change the degree of body tightening by the mat. Therefore, when the blood pressure rises, the tightness of the body by the mat can be weakened, a large fluctuation of the blood pressure can be prevented, and the patient can be prevented from feeling unwell.

  Further, in the present invention, when the detection device capable of detecting the elapsed time and the pressure adjusting device for adjusting the pressure of the fluid in the mat based on the elapsed time are provided, the fluid in the mat is obtained when the predetermined time has elapsed. The pressure can be varied. Accordingly, the shape of the mat can be changed at regular intervals, and the posture of the patient can be changed by the change in the shape, so that the patient's pressure ulcer can be automatically suppressed.

In one embodiment,
The mat includes a laying mat on which the body is placed and a hanging mat that covers the body.

  Note that the fluid pressure of the mat and the mat mat may be the same or different from each other.

  According to the above embodiment, the mat has the mat for placing the body and the hanging mat for covering the body, and the mat has a swallow-like structure for wrapping the baby. Therefore, since the mat wraps around a person, even if the person can stand from a sleeping position to a standing position, the mat can stably hold the person and the person falls from the bed. Can be prevented.

  In particular, in the above-described embodiment, when a detection device capable of detecting a blood pressure value and a pressure adjustment device that adjusts the pressure of the fluid in the mat based on the blood pressure value are provided, If the fluid pressure of the hanging mat is reduced according to the rise, it is possible to suppress a large rise in blood pressure when the bed is standing up, and to reduce the possibility that a person will be offended.

In one embodiment,
A plurality of particulates arranged in the mat are provided.

  According to the above embodiment, since there are a plurality of particulate bodies in the mat, when the fluid pressure in the mat is lowered, the shape of the mat is changed to the shape of a human body on the mat with the plurality of particulate bodies. It can be a shape that follows. Therefore, when the fluid pressure is low, it is possible to realize a hard state that wraps and holds the body.

In one embodiment,
A bed frame that supports the mat;
And an inclination mechanism that supports the bed frame so as to be inclined with respect to a horizontal plane.

  According to the embodiment, the person who is sleeping is not forced to stand up, and the person who is sleeping can be supported.

  According to the bed system of the present invention, an increase in blood pressure based on the compression of the mat can be alleviated, the patient can be less likely to feel unwell, and the occurrence of pressure sores can be suppressed.

The two hinges 18, the two telescopic cylinders 16, and the two support arms 19 constitute a tilt mechanism that supports the bed frame 2 so as to be tiltable with respect to the carriage.

  The support carriage 11 (tilting mechanism) can tilt the capsule 10 (bed frame 2) as a whole. Specifically, the bed frame 2 can be tilted (maintained horizontal) by extending the telescopic cylinder 16. Further, the bed frame 2 can be erected by shortening the telescopic cylinder 16.

  FIG. 2 is a main configuration diagram of the bed system 1.

  As shown in FIG. 2, the bed system 1 includes two air pumps 4 </ b> A and 4 </ b> B, a control device 5, an operation device 6, a time measuring device 7, and a sphygmomanometer 8 in addition to the bed frame 2 and the mat 3. The time measuring device 7 measures the elapsed time, and the sphygmomanometer 8 detects the blood pressure value of the person. The time measuring device 7 and the sphygmomanometer 8 constitute a detection device. The control device 5 can receive a signal representing the elapsed time from the time measuring device 7, a signal representing the blood pressure from the sphygmomanometer 8, and a signal representing the air pressure from the operation device 6. Further, the control device 5 can output a control signal representing the amount of air to the air pumps 4A and 4B. The control device 5 and the air pumps 4A and 4B constitute a pressure adjusting device. The control device 5 can output a signal indicating the degree of expansion / contraction to the two expansion / contraction cylinders 16 (see FIG. 1). The operator can drive or stop the air pumps 4A, 4B by using the operating device 6. Further, the operator can use the operating device 6 to stop the capsule 10 (see FIG. 1) at a free inclination angle with respect to the horizontal plane when the wheel 17 is placed on the horizontal plane. It can be made to stand still in a parallel state. As shown in FIG. 2, the mat 3 includes a laying mat 30 </ b> A on which the body H is placed and a hanging mat 30 </ b> B that covers the body H.

  FIG. 3 is a schematic front sectional view of the mat 3.

  Referring to FIG. 3, the mat 30 </ b> A has one end side magic tape portion 80 at one end portion in the width direction, and has the other end side magic tape portion 81 at the other end portion in the width direction. The hook mat 30B has one end side magic tape portion 90 at one end in the width direction, and has the other end side magic tape portion 91 at the other end in the width direction. As shown in FIG. 3, one end side magic tape portion 80 of the mat mat 30A is locked to one end side magic tape portion 90 of the hanging mat 30B, while the other end side magic tape portion 81 of the mat mat 30A is engaged with the hanging mat 30A. The other end side magic tape part 91 of 30B is latched. In this way, the hanging mat 30B can be locked to the laying mat 30A. The laying mat 30A includes a bag body 31A and a plurality of beads 33 arranged in the bag body 31A. Each of the beads 33 constitutes a particulate body. Each of the beads 33 may be made of a hard resin material such as plastic, and may be made of a resin such as plastic. Moreover, each said bead 33 may consist of soft materials, for example, may consist of elastic members, such as rubber | gum. The bag body 31 is made of a soft material and can be deformed by a load applied to the bag body 31. The bag body 31 has an opening, and a filter is provided in the opening. The filter allows passage of air 32 but does not allow passage of beads 33. Similarly, the hanging mat 30B has a bag body 31B and a plurality of beads 33 arranged in the bag body 31B. A filter is provided in the opening of the bag body 31B.

  The two air pumps 4A and 4B are connected to the opening of the bag body 31A and the opening of the bag body 31B via the air pipe 41, respectively. Each of the air pumps 4A and 4B can perform suction or discharge of air as an example of a fluid at the time of driving, and hinder movement of air when stopped. The air pump 4A can change the amount of air 32 in the bag 31A. The air pump 4A can maintain a state in which the amount of air 32 in the bag 31A does not fluctuate. Similarly, the air pump 4B can change the amount of air 32 in the bag 31B. The air pump 4B can maintain a state in which the amount of air 32 in the bag 31A does not vary.

  Hereinafter, the state of the mat 30 </ b> A will be described with reference to FIGS. 4, 5, 6, and 7. The mat 30A can be in a standard state (FIGS. 4 and 5), a deaerated state (FIG. 6), and an air-filled state (FIG. 7).

  FIG. 4 is a schematic cross-sectional view of the mat 30A when no load is applied in the standard state.

  The standard state represents the state of the mat 30A when a person goes to sleep. In this state, the amount of air in the bag 31A is kept constant. In FIG. 4, the upper surface 35A of the mat 30A is substantially in the same plane.

  FIG. 5 is a schematic cross-sectional view of the mat 30A when the body H is placed in the standard state.

  When the body H is placed on the standard mat 30 </ b> A of FIG. 4, the mat 30 </ b> A is deformed due to the load of the body H. Here, the driving of the air pump 4A is stopped, and the volume of the bag 31A does not change between FIG. 4 and FIG. For this reason, in FIG. 5, the mat 30 </ b> A is deformed into a recessed shape. In the standard state, the mat 30A is in a soft state that deforms along the body shape. In the standard state, the mat 30 </ b> A can be adapted to the shape of the object using the fluidity of the beads (particles) 33.

  FIG. 6 is a front sectional view of the mat 30A when the body H is held in the deaerated state.

  The deaeration state is defined as a state in which the amount of air in the bag body 31 is small and the volume in the bag body 31 is small compared to the standard state of FIGS. When air 32 is sucked from the mat mat 30A in the standard state shown in FIG. 5 by driving the air pump 4A, the volume of the bag 31A is reduced. Thereafter, when the driving of the air pump 4A is stopped, the volume of the bag 31A becomes constant, and the state of the mat 30A becomes a deaerated state. In the deaerated state, the mat 30A can be deformed so as to wrap the body H. The deaerated state is a hard state that wraps and holds the body. In the deaerated state, the mat 30A can wrap and hold the object by deaeration.

  FIG. 7 is a schematic front cross-sectional view of the mat 30A when the body H is held in the air-filled state.

  The air-filled state is defined as a state in which the amount of air in the bag body 31 is large and the volume in the bag body 31 is large compared to the standard state of FIGS. The air-filled state is realized by supplying air 32 from the standard state to the mat 30A. In the air-filled state, the amount of air in the mat 30A is constant. The air-filled state is a hard state that supports the body by applying pressure. In the air-filled state, the mat 30A can support the object in a state where pressure is uniformly applied to the object by filling the air. In addition, in FIG. 4 to FIG. 7, the standard state, the deaerated state, and the air filling state have been described using the mat 30A, but the hanging mat 30B is similarly in the standard state, the deaerated state, or the air filled state. Can be taken. Also in the hanging mat 30B, the standard state is a state that can be suitably used when going to bed. In the hanging mat 30B, the air amount in the hanging mat 30B is larger in the standard state than in the deaerated state, and the air in the hanging mat 30B is more in the air-filled state than in the standard state. The amount is increasing.

  In the above configuration, in the bed system 1, a person sleeping on the mat 30A can stand, for example, as follows.

  Specifically, first, before standing a person sleeping on the mat 30A, a nurse or the like uses the operation device 6 to degas the mat 30A while the mat 30B is aired. Fill state. In this state, the operating device 6 is used to gradually reduce the telescopic cylinder 16 so that the capsule 10 is gradually inclined from a state substantially parallel to the horizontal plane to a state where a person can stand upright in the vertical direction. It has become.

  Further, during the tilting operation of the capsule 10, the control device 5 always receives a signal from the sphygmomanometer 8. When the blood pressure rises by a predetermined value or more, the operation of the telescopic cylinder 16 is temporarily stopped, the inclination of the capsule 10 is temporarily stopped, and the air is removed from the hanging mat 30B. The pressing force received by the person from the mat 30B is reduced. In this way, an increase in blood pressure when the person gets up is suppressed so that the person is less likely to feel sick. Whether or not the body H is receiving pressure from the mat 3 is determined by, for example, measuring the contact pressure on the surface of the mat 30A on the side of the mat 30A or the surface of the mat 30B on the side of the mat 30A. If a pressure sensor is installed, it can be judged more objectively.

  Moreover, this bed system suppresses pressure sores (bed slip) by performing the following control.

  That is, when the user inputs a signal indicating pressure ulcer suppression from the operation device 6 to the control device 5, the timing device 7 receives a signal indicating the start of time from the control device 5 and starts measuring time. Yes. At the same time, the control device 5 outputs a signal indicating that the mat 3 is brought into the standard state to the pumps 4A and 4B so that the mat 3 which has been sucked in air from the pumps 4A and 4B is brought into the standard state. It has become.

  Next, when receiving the first signal indicating that the first predetermined time has elapsed from the time measuring device 7, the control device 5 outputs a signal for setting the mat 3 to the air filling state to the pumps 4A and 4B. ing. Then, the pumps 4A and 4B receive the signal and send air into the mat 3 so that the mat 3 is filled with air.

  Next, when receiving the second signal indicating that the second predetermined time has elapsed since the time measuring device 7 outputs the first signal, the control device 5 sends the mat 3 to the pumps 4A and 4B. A signal indicating that the is in a standard state is output. Then, the mat 3 is in a standard state by sucking air from the pumps 4A and 4B.

  Thereafter, the time measuring device 7 outputs the first signal to the control device 5 when the first predetermined time elapses after outputting the second signal to the control device 5. Thereafter, the above-described control is repeated. The repetition of this control is continued until the user inputs a signal indicating release of pressure ulcer suppression to the operation device 5.

  In this embodiment, the first predetermined time and the second predetermined time can be input directly from the operating device 6 to the time measuring device 7 or indirectly from the operating device 6 via the control device 5. It is possible to input to the timing device 7. The first predetermined time can be suitably set to, for example, 15 minutes, 30 minutes, 1 hour, 1 hour and a half, and the second predetermined time is 1 minute, Times such as 1 minute 30 seconds and 2 minutes can be suitably set. However, it goes without saying that the first predetermined time and the second predetermined time can be set to other times.

  Briefly, the control device 5 controls the air pumps 4A and 4B so that the volumes of the bag bodies 31A and 31B periodically change based on the elapsed time. Here, when the volume of the bag bodies 31A and 31B changes with time, the body H is rocked in the mat 3, and the contact position between the body H and the mat 3 changes. For this reason, generation | occurrence | production of a bed slip is prevented. Note that when the mat 3 is kept horizontal, the hanging mat 30B may be removed, or only the mat 30A may be used.

  According to the above-described embodiment, the blood pressure monitor 8 capable of detecting the blood pressure value and the pressure adjusting device that adjusts the pressure of the fluid in the mat 3 based on the blood pressure value are provided. The pressure of the fluid can be changed, and the degree of body tightening by the mat 3 can be changed. Therefore, when the blood pressure rises, the degree of body tightening by the mat 3 can be weakened, and the patient can be prevented from feeling unwell.

  Moreover, according to the said embodiment, since the time measuring device 7 which can detect elapsed time and the pressure adjustment apparatus which adjusts the pressure of the fluid in the mat 3 based on elapsed time are provided, when elapsed time passes for a fixed time, The fluid pressure in the mat 3 can be varied. Therefore, the repulsive force of the mat 3 can be changed at regular intervals, and the patient's body position can be changed by the fluctuation of the repulsive force, so that the pressure ulcer of the patient can be automatically suppressed. Therefore, the burden on caregivers such as nurses can be significantly reduced.

  Moreover, according to the said embodiment, the mat 3 has the mat 30A on which the body is placed, and the hanging mat 30B which is put on the body, and the mat 3 has a swallow-like structure that wraps the baby. Yes. Therefore, since the mat 3 has a structure that wraps the person, even if the bed has a structure in which the person can stand up from a sleeping position to a standing position, the person can be stably held by the mat 3.

  Moreover, according to the said embodiment, it is the structure where the bed can stand, and the blood pressure meter 8 which can detect a blood pressure value, and the pressure adjustment apparatus which adjusts the pressure of the fluid in the mat 3 based on a blood pressure value Therefore, the fluid pressure of the hanging mat 30B can be reduced when the blood pressure rises by a predetermined level or more during the bed standing operation. Therefore, when the bed is raised, it is possible to suppress a person from receiving an unfavorable pressing force from the hanging mat 30B, and it is possible to reduce the possibility that the person will be offended.

  Further, according to the embodiment, since the plurality of beads 33 exist in the mat 3, when the fluid pressure in the mat 3 is lowered, the shape of the mat 3 on the mat 3 is changed with the plurality of beads 33. It can be shaped along the shape of the human body. Therefore, when the fluid pressure is low, it is possible to realize a hard state that wraps and holds the body.

  Moreover, according to the said embodiment, since it is equipped with the inclination mechanism which supports the bed frame 2 so that it can incline with respect to a horizontal surface in a use condition, it does not force the person who sleeps to stand up, and the person who is sleeping Can support the rise.

  In the above embodiment, the mat mat 30A and the mat mat 30B are provided, and the fluid pressures of the mat mat 30A and the mat mat 30B can be set independently of each other. However, in the present invention, the fluid pressure of the matting mat and the fluid pressure of the hanging mat may always be the same, and the fluid pressure of the matting mat and the fluid pressure of the hanging mat may be temporary or all the time. However, they may be different from each other.

  Moreover, in the said embodiment, although the mat had the covering mat 30A and the hanging mat 30B, in this invention, only a covering mat may be sufficient as a mat.

  Moreover, in the said embodiment, the bed system was equipped with the inclination mechanism, and the bed frame 2 was able to be made to be able to incline to a free angle with respect to a horizontal surface, and to be able to change in use condition. However, in the present invention, the bed frame may not have an inclination mechanism, and may not be able to fluctuate with respect to a horizontal plane in a use state. Moreover, in the said embodiment, although the bed system 1 had the wheel 17, in this invention, even if the bed system is a structure which has a well-known four leg part without having a wheel. good. In the present invention, the bed system may have a known configuration including a frame portion for placing the mat floor and four leg portions.

  In the above embodiment, the fluid sealed in the mat 3 is air. However, in the present invention, the fluid sealed in the mat may be a gas other than air or water. It may be a liquid other than water or a gel-like substance.

  In the above embodiment, the plurality of beads 33 are enclosed in the mat 3, but in the present invention, any particulate matter other than the beads may be enclosed in the mat. Alternatively, pipe particles, wooden particles, latex, particles made of rubber, etc. may be enclosed. Moreover, in this invention, it is not necessary to enclose the particulate matter in at least one mat.

  Moreover, in the said embodiment, the detection apparatus had the time measuring device 7 and the sphygmomanometer 8, and it has implement | achieved both blood pressure control and pressure ulcer suppression. However, in the present invention, the detection device has a time measuring device, but may not have a blood pressure monitor, and the bed system may not be able to control blood pressure and only suppress pressure ulcer. Moreover, in this invention, while having a sphygmomanometer, it is not necessary to have a timing device, and the bed system may not be able to suppress pressure ulcer but only to control blood pressure.

  Moreover, in the said embodiment, pressure ulcer suppression was performed by changing the posture of a human body by making the mat | matte mat | matte 30A of a standard state into an air filling state, and then making it into a standard state. However, according to the present invention, the bed mat in the standard state may be deaerated and then returned to the standard state to change the posture of the human body so as to suppress pressure ulcers. Alternatively, the standard mat may be deaerated after being filled with air, and then returned to the standard state to suppress pressure ulcers, or the standard mat may be deaerated. After that, it may be in an air-filled state, and then returned to the standard state to suppress pressure ulcer. Further, in the present invention, pressure ulcer suppression may be performed by changing the body position of the person by changing the amount of fluid in the laying mat in a complicated manner over a certain period of time. In the present invention, pressure ulcer suppression may be performed by periodically changing the amount of fluid in the mat and performing any control to deform the mat.

  In the above embodiment, the pressure sensor is present on the surface of the mat 30A on the side of the mat 30B, and the pressure sensor is also present on the surface of the mat 30B on the side of the mat 30A. However, in the present invention, the pressure-sensitive sensor may be present only on the surface of the laying mat on the side of the laying mat, or the pressure-sensitive sensor may be present only on the surface of the laying mat on the side of the laying mat. In the present invention, when only the mat is present, a pressure sensor may be disposed on the mat, and in the present invention, no pressure sensor may be present at all.

  Moreover, in the said embodiment, the mat | matte mat 30A and the hooking mat | matte 30B were latched with the magic tape in two places. However, in the present invention, as shown in FIG. 8, that is, a schematic diagram of the mat 103 of the modified example, the mat mat portion 130A and the hook mat portion 130B are connected via the connecting portion 140, and the mat mat portion 130A A configuration in which the magic tape portion 141 exists on the side opposite to the connection portion 140 side in the width direction and the magic tape portion 142 exists on the side opposite to the connection portion 140 side in the width direction of the hook mat portion 130B may be adopted. Then, by engaging the magic tape part 141 and the magic tape part 142, the mat 103 may surround the body. In the present invention, the mat may have a sleeping bag-like structure. Moreover, it is needless to say that a new embodiment can be constructed by combining two or more of the configurations described in the above embodiments and modifications.
