Description

  The present invention generally relates to a nursing bed, and more particularly to a nursing bed improved so as to prevent bedsores.

  FIG. 7 is a perspective view of the main body of the care bed. The care bed includes a main frame 1 and a side frame 2. On the main frame 1, there is provided a bottom plate 3 having a structure that can be bent substantially at the center. A head board 4 and a foot board 5 are provided on the head side and the foot side of the bottom plate 3. A handrail 6 is provided on the side of the bottom plate 3. At the time of use, as shown in FIG. 8, a mattress 7 made of urethane foam is placed on the bottom plate 3, and the patient is laid on the mattress. Since the bottom plate 3 can be bent at the center portion, the head side of the bottom plate 3 is lifted by the mechanical force to lift the head side of the mattress 7, and the patient's upper body is raised as shown in the figure. Can be made.

  The conventional nursing bed is configured as described above.

  By the way, in the case of a bedridden patient, if the patient's body is tilted or turned sideways for about 2 hours and the body position is not changed for 10 to 15 minutes, the blood flow is inhibited, and the cells in the compressed part for a long time are necrotic. And so-called pressure ulcer develops. A pressure ulcer arises from the bed slip part shown by the oblique line part in FIG. The bedsore part can be easily formed on the occipital region 10, the shoulder 11, the scapula 12, the spinal cord 13, the elbow 14, the sacrum 15, the greater trochanter 16, the inner side 17 of the knee, and the heel 18. It is important to prevent pressure ulcers from occurring rather than treating them. Therefore, body posture exchange is performed in order to distribute and support body pressure without concentrating it on a specific part. However, since the work of changing the position of a bedridden patient every two hours is a heavy labor, caregivers often hurt their backs. On the other hand, the patient whose position is to be exchanged also takes a cramped body shape every two hours, and sleep is interrupted during bedtime, so he cannot sleep well.

  In addition, even if such posture changes are frequently performed, the risk of developing pressure sores may increase due to changes in the nutritional status and immunity of the patient. In such a case, an air mat is often used. However, the air mat is inevitably applied with a strong pressure on a part of the patient's body.

  However, the basic principle is that pressure should not be applied to the body of a patient at risk of pressure ulcers, but if there is no other way, it is allowed for a short time, but temporarily It is the substance that puts pressure on the patient. Therefore, I want to avoid giving such a burden to the patient in a short time if possible.

  The present invention has been made to solve the above-described problems, and provides an improved care bed so as to prevent pressure ulcers of patients with a high risk of pressure ulcers by supporting rolling over. The purpose is to do.

  Another object of the present invention is to provide an improved nursing bed so that the posture can be automatically changed.

  Another object of the present invention is to provide a care bed improved so that the body position can be changed without interrupting sleep even while the patient is sleeping.

  Another object of the present invention is to provide an improved care bed so that a caregiver can change the position of a patient without hurting his / her waist.

  It is still another object of the present invention to provide an improved care bed that can also be used to massage a patient's body.

  A nursing bed according to the present invention is provided on a bottom plate, a headboard and a footboard provided on a head side and a foot side of the bottom plate, a handrail provided on a side portion of the bottom plate, and the bottom plate. And a mattress formed of natural rubber foam.

  According to the present invention, since the mattress is formed of a natural rubber foam, it has excellent body pressure dispersion capability, and pressure ulcer can be prevented without changing the posture for a long time.

  According to a preferred embodiment of the present invention, the base plate and the mattress are provided in parallel to each other so as to extend from the headboard side to the footboard side, and are alternately inflated by inflating with the air. It further includes a pair of air bags that alternately incline the mattress. If comprised in this way, a mattress can be made to incline alternately with the force of air, and the patient on a mattress can be inclined to right and left by extension.

  It is further preferable that at least one of the pair of air bags is divided into two parts, a head side and a foot side, so that air can be inflated independently of each other.

  With this configuration, the patient on the mattress can be tilted left and right, and only the right or left foot can be raised.

  It is preferable that the inclination angle of the mattress can be adjusted by the amount of air to be put into the air bag. By comprising in this way, position exchange according to a patient's symptom can be performed now.

  In the care bed according to another aspect of the present invention, a plurality of air bags extending from the headboard side to the footboard side are parallel to each other in the width direction of the patient's body between the bottom plate and the mattress. Thus, the mattress can be undulated in the width direction of the patient's body in order by independently sending and exhausting air at time intervals to each air bag.

  In the care bed according to still another aspect of the present invention, a plurality of air bags extending in the width direction of the patient's body are parallel between the bottom plate and the mattress from the headboard side toward the footboard side. It is arranged so that the mattress can be waved in the height direction of the patient in sequence by sending and exhausting air independently with a time interval between each air bag.

  The mattress is made of 100% natural latex foam rubber.

  It is preferable to slightly change the depth of the hole of the natural rubber foam according to each part (head, back, buttocks, and feet).

  Furthermore, the surface of the mattress is preferably covered with a film that cuts off ultraviolet rays.

  According to the care bed according to the present invention, pressure ulcers can be prevented without changing the posture for a long time. Moreover, pressure ulcer prevention can be performed for patients with a high risk of pressure ulcer only by changing the position every few hours.

  The purpose of obtaining an improved care bed to prevent pressure ulcers for patients with high risk of pressure ulcers was realized by forming the mattress on the bottom plate with natural rubber foam. . Embodiments of the present invention will be described below with reference to the accompanying drawings.

  FIG. 1 is a conceptual diagram of a portion above the bottom plate 3 of the nursing bed according to the first embodiment. The bottom plate 3 and the portion below it are the same as in the conventional example shown in FIG. The nursing bed according to this embodiment is different from the conventional example shown in FIG. 5 in that the mattress 20 is formed of a natural rubber foam. Natural rubber foam is made of 100% natural latex foam rubber. 100% natural latex foam rubber is made from rubber sap. By forming the mattress 20 from a natural rubber foam, the body 21 sinks into the mattress 20 and the body pressure is dispersed in the direction of the arrow. Bed slippage results from pressure on the same part of the body for a long time, but according to this embodiment, it is possible to reduce and disperse this pressure, improve blood circulation of capillaries, and continuous pressure on body tissues. Can be eliminated, and bedsores can be prevented.

  FIG. 2 is a diagram showing the pressure of the weight applied when a person goes to sleep in comparison with an example and a comparative example. FIG. 2A is a diagram showing the result of measuring the pressure of the body weight using the nursing bed according to this example, and FIG. 2B is the diagram using the conventional nursing bed according to the comparative example. It is the figure which showed the result of having measured the pressure of the body weight. A portion 31 indicated by point hatching represents a portion where the pressure is applied to 2 to 8 mmHg, and a hatched portion 32 is a portion applied to the pressure of 50 mmHg, and a portion indicating this pressure is a pressure ulcer occurrence risk zone. 2A and 2B, according to the present embodiment, the pressure ulcer occurrence risk zone 32 to which 50 mmHg pressure is applied is almost eliminated, and it is obvious that it is dispersed.

  In addition, since a lot of body pressure is applied to the protruding part of the body, considering this, the hole depth of the natural rubber foam is adjusted to each part (head, back, buttocks, feet) It is preferable to change to Thereby, body pressure can be dispersed optimally, and bedsores can be prevented more optimally.

  The degree of foaming is quantified by hardness, and is roughly divided into soft (10.2 kgf or less), medium (10.2 to 17.2 kgf), and hard (12.2 kgf or more). A soft one is preferably used for patients with a large degree of pressure ulcer.

  In addition, natural rubber foam tends to deteriorate when exposed to ultraviolet rays, and therefore it is preferable to cover the mattress with a film that cuts ultraviolet rays. It is preferable to cover the mattress with a margin so that there is a gap between the mattress and the UV cut film, so that it does not prevent the body from sinking into the mattress. .

  In addition, if the hole in the natural rubber foam has a continuous foam structure in which bubbles are adhered to each other from the front surface to the back surface, a passage through which air flows is formed as shown in FIG. It is possible to remove moisture (humidity) 41 that causes water vapor.

  FIG. 4A is a conceptual diagram of a portion above the bottom plate 3 of the nursing bed according to the second embodiment. The bottom plate 3 and the portion below it are the same as in the conventional example shown in FIG.

  In the nursing bed according to the second embodiment, a pair of air bags 40a and 40b are arranged in parallel to each other so as to extend from the headboard side to the footboard side between the bottom plate 3 and the mattress 20 formed of natural rubber foam. Has been. By alternately inflating the pair of air bags 40a and 40b with air, the mattress 20 can be inclined alternately. A hose 41 is attached to the pair of air bags 40a and 40b, and the hose 41 is connected to a pump (not shown).

  Referring to FIG. 4 (B), when the air bag 40a on the right shoulder side is inflated by the air blown from the pump, the left shoulder can be turned over. Referring to FIG. 4 (C), the left shoulder side air bag 40a can be turned over. When the air bag 40b is inflated, it can be turned over to the right. The inclination angle can be adjusted according to the amount of air that enters the air bags 40a, 40b, and the maximum right / left inclination angle is set within 20 degrees. This operation is performed automatically, and the patient can be slowly tilted to the left and right without placing a burden on the patient. Therefore, the conventional posture change every 1 to 2 hours is not required, and the patient can sleep well. .

  In addition, even patients who have difficulty moving their bodies can turn over without difficulty and relieve back and back pain. You can also wake up by grabbing the handrail with both hands using the left and right tilt. Being able to get up makes it possible to get out of bed, and the patient is more motivated to become independent, and can move toward further functional recovery. On the other hand, the caregiver can also change the position of the patient without hurting the lower back.

  In the above embodiment, the case where two air bags extending from the headboard side to the footboard side are illustrated, but the present invention is not limited to this, as shown in FIG. A plurality of air bags 40 extending from the headboard side to the footboard side are arranged between the bottom plate and the mattress at intervals in the width direction of the patient's body so as to be parallel to each other. A time interval is provided in the air bag 40, and a pump (not shown) is used to send and exhaust air independently via the feeding hose 41a and the exhausting hose 41b, and the air bags 40 are sequentially inflated and shrunk. By doing so, the mattress may be waved in the width direction of the patient's body.

  Further, as shown in FIG. 5B, a plurality of air bags 40 extending in the width direction of the patient's body between the bottom plate and the mattress are parallel to each other with a gap from the headboard side to the footboard side. By using computer control, air is sent independently through the feeding hose 41a and the exhausting hose 41b by using a pump (not shown) with a time interval between them. The mattress may be waved in the height direction of the patient by exhausting and sequentially inflating and contracting each air bag 40. By comprising in this way, the massage effect is acquired.

  The fourth embodiment is a further modification of the care bed according to the second embodiment. As shown in FIG. 6, each of the pair of air bags 40a and 40b includes a head side 40a-1 and a head side 40a-2. The hose 41a and the feeding hose 41a are divided into two parts, the foot side 40b-1 and 40b-2, by using a pump (not shown) at intervals in each air bag 40 under computer control. Air is independently sent and exhausted through the exhaust hose 41b so that each air bag can be inflated and contracted sequentially. With this configuration, the patient on the mattress 20 can be tilted left and right, and only the right foot or the left foot can be raised.

  In addition, in this modification, although the case where each of a pair of air bags 40a and 40b was divided | segmented into two parts was illustrated, this invention is not limited to this, Only one side is divided | segmented and three parts May be inflated with air alternately and alternately depending on the patient's symptoms.
