DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a padded diaper cover capable of preventing a local sustained compression and preventing the occurrence of a pressure sore.

[0002]

2. Description of the Related Art In recent years, pressure sores of elderly people have become an important problem not only in hospitals and facilities, but also in home care and nursing care sites. In addition, it is said that such a pressure sore accounts for 40% of the causes of sepsis in the elderly, which is another etiology.

[0003] The cause of pressure sores is ischemic necrosis of tissue due to compression. Therefore, the site where the pressure sore is likely to be formed is a bone projection to which a high pressure is applied, as shown in FIG. Such necrosis occurs under a large pressure even for a short time, and occurs under a small pressure after a long time.

[0004] Here, for example, a circular seat 200 shown in FIG. 15 is frequently used as a device for preventing such continuous compression and preventing a pressure sore. The circular seat 200 is a substantially ring-shaped body having a hole 210 in the center, and is formed by filling a bag-like body with a filler capable of dispersing body pressure.
Then, the circular seat 200 is arranged, for example, below the buttocks, and a bone projection such as a sacrum is arranged in the central hole 210 so that compression at the bone projection can be avoided.

[0005]

However, since an elderly person has no muscle or fat and has protruded bones, as shown in FIG. In the hole 210, the sacral portion S may be pressed against the bedding, causing the sacral portion S to be pressed. Further, when the contact portion moves due to the change of the body position, the filling material is moved, the filling material decreases at the contact portion, and the contact portion may be pressed at the ring portion. Such inconvenience has also occurred in other air pressure mattresses, bead mats, and buckwheat mats, which are other devices for preventing pressure sores. In other words, there is no pressure sore prevention device that can change the shape while having an appropriate body pressure dispersing function and can easily cope with a change in the body position of a patient or a difference in body shape, and there is a demand for a device that can further reduce the burden on a caregiver. Was. In addition, since the sacral region is a frequent site of a pressure sore and also a severe site, a tool that can easily prevent such a pressure sore at the sacral site has been demanded.

Accordingly, an object of the present invention is to provide a pad which can maintain a body pressure dispersing function and reliably prevent pressure contact of a bone protrusion. Another object of the present invention is to provide a diaper cover with a function to prevent pressure sores.

This is a diaper cover for preventing pressure sores.

Hereinafter, the present invention will be described in detail. According to the present invention, a part that abuts on a bone protrusion and a part that abuts around the bone protrusion have a separate chamber configuration, and the surrounding abutment part of the bone protrusion has a plurality of chambers, so that the user can change the body position and shape Regardless, the body pressure dispersing function can be maintained. That is, the present invention has solved the drawbacks of the conventional tool in which the pressing of the bone protruding portion could not be sufficiently avoided depending on the shape of the bone protruding portion of the user and the body pressure dispersing function of the circular seat.

[0013] Here, the bone protruding portion refers to a portion of the body where the bone is protruded and the body weight is likely to be applied when the patient lies on his / her back, sideways, etc. Specifically, the shoulder and scapula shown in FIG. , Spine, iliac, sacral, greater trochanter, ankle.

According to the present invention, the contact portion filled with the flowable filler is positively provided to avoid pressure contact between the bone protrusion and the bedding, and the pad is separated from the contact portion and the plurality of chambers. With this configuration, the body pressure applied to the bone protrusion can be evenly distributed over the entire pad.

Here, the abutting portion refers to a portion provided corresponding to the bone protruding portion and abutting on the bone protruding portion. For example, in the pad for preventing pressure wounds on the sacrum, the pad is in contact with the sacrum. Further, the outer peripheral portion is a portion provided on the outer periphery of the contact portion so as to be able to disperse the pressure to the bone protruding portion contacting the contact portion. It may surround the entire outer periphery of the contact part, or may be provided partially on the outer periphery of the contact part.

Since the outer peripheral portion has at least two chambers, the filler does not escape even in the outer peripheral portion where the load increases due to a change in body position or a change in body pressure, and an appropriate body pressure dispersing function is maintained. It is supposed to be.

In order to maintain the appropriate body pressure dispersing function as required, it is necessary that each chamber of the contact portion and the outer peripheral portion is filled with an appropriate amount of the fluid filler. Therefore, it is desirable that an inlet is formed in each of the bag-shaped body of the contact portion and each hollow portion of the outer peripheral portion so that the amount of the fluid filler in each chamber can be adjusted.

Here, the term "fluid filling material" refers to a filling material that flows according to body pressure. For example, a fluid such as a gas or liquid such as water or air, or a semi-solid such as a gel or a colloid. Examples thereof include fluids, aggregates of solid granular materials such as beads and cylindrical materials made of various materials. Air is preferred because it can be easily and inexpensively procured, and it is easy to put in and out, and it is lightweight.

In addition, the pressure-resistant wound preventing pad of the present invention is such that an electrode (switch) which is brought into contact when the bag-like body constituting the contact portion is pressed in the direction in which the body pressure is applied, to be in a conductive state.
Is provided. In the display through this electrode,
By being able to display the conduction state, the contact portion is pressed by excessive body pressure, and the inner surface of the bag-like body constituting the contact portion comes into contact with or comes close to the body portion, and the body pressure dispersing function is reduced. In this case, this state (so-called bottomed state) can be detected.

Therefore, the caregiver can detect the bottom of the contact portion by confirming the display on the display, thereby recognizing the necessity of changing the position of the patient, and merely at predetermined time intervals. Does not need to be repositioned. As a result, care is streamlined. Note that the display device detects the conduction state due to the contact of the electrodes, and the conduction state can be detected by turning on or blinking a lamp, transmitting a sound wave such as a buzzer or a sound or a radio wave, or monitoring a screen. Anything should do.

Furthermore, pressure sore prevention pad of the present invention, those
Filling means for filling the hollow chamber of the contact portion with air;
Has a tonometer that can detect the pressure applied to
You. This detects the pressure applied to the contact area and
The air amount can be filled in the contact portion. Furthermore, on the outer periphery
The pressure gauge is also provided on the outer periphery by providing air
From the pressure value at the contact part by
Filling is possible. At this time, backflow prevention
A stop valve can be provided. The check valve provided in each of the outer peripheral chambers is provided so that when the load moves, air moves from the load-applied chamber and the body pressure dispersing function in the chamber does not decrease.

Therefore, the adjustment according to the body pressure applied to the contact portion is possible, and the prevention of the pressure sore is reliably achieved.
In addition, the body pressure, the time, and the air filling amount detected by the tonometer can be controlled by a computer to automatically perform air filling and the like.

Further, the pad for preventing pressure sores of the present invention is provided with an auxiliary pad portion capable of changing the position on the outer peripheral portion. By this auxiliary pad part, at the time of posture change, one pad for pressure sore prevention is provided for the bone protrusion that needs to be newly protected,
It can be easily handled. Further, when used in a state of being superposed on the outer peripheral portion, the body pressure dispersing function of the outer peripheral portion can be adjusted without adjusting the amount of the fluid filler. Therefore, the prevention of pressure sores can be easily and reliably prevented in accordance with the change in body position.

In addition, by using such a pad for preventing pressure wounds on the diaper cover and using it integrally with the diaper cover, it is possible to effectively prevent the pressure wound on the sacrum where the pressure wound is likely to occur. it can. In addition, the pad for preventing pressure wounds is moved with the movement of the body, and the pad for preventing pressure wounds is always placed at a predetermined position on the body.Therefore, the pad should be positioned every time sheets are changed or the body position is moved. This saves time and effort.

[0030]

Next, an embodiment of the present invention will be described. (Embodiment 1) Hereinafter, Embodiment 1 will be described with reference to FIGS.
Will be described. FIG. 1 shows a pressure sore prevention pad (hereinafter simply referred to as a pad) 1 according to the present embodiment.
The pad 1 is for preventing pressure wounds of the sacrum, is filled with air in the hollow chamber of the bag-like body, and has a thickness and a moderate cushioning property.

The pad 1 is composed of a central contact portion 2 and an outer peripheral portion 8 provided integrally on the outer periphery thereof. The contact portion 2 is a portion that contacts the sacral portion S, and is formed in a bag-like body capable of forming a substantially cylindrical hollow chamber 2a filled with air. On the opposite side of the abutment portion 2 that is not the abutment side of the sacral portion S, an air inlet 6 is opened in a sealable manner.

The outer peripheral portion 8 is formed integrally with the abutting portion 2 in a ring shape so as to surround the abutting portion 2 so as to abut around the sacral portion S. The outer peripheral portion 8 is
Bag-like body 1 divided into two hollow chambers 8a and 8b on the left and right sides
0a and 10b. Each hollow chamber 8 of the outer peripheral portion 8
a, 8b are filled with air so as to be slightly thicker than the contact part 2, and each of the bag-like bodies 10a,
10b is provided with air inlets 12a and 12b that can be sealed at portions that do not abut around the sacrum.

In each of the hollow chambers 2a, 8a, 8b of the pad 1 thus formed, an appropriate amount of air is sealed from the inlets 6, 12a, 12b, respectively, as shown in FIG. 1 (b). It has a three-dimensional shape.

Next, the operation and effect of the use of the pad 1 thus formed will be described. FIG. 2 shows a state in which the pad 1 is laid under the sacral portion S of the body and the sacral portion S
FIG. 3 is a view in which the cross section of FIG. In the pad 1 of the present embodiment, the periphery of the sacral portion S is the outer peripheral portion 8.
The load applied to this portion is dispersed, and the sacral portion S, which is the heaviest load, protrudes downward. However, since the contact portion 2 abuts here, the sacral portion S is Is prevented from being pressed against. As a result, the pressure wound of the sacral region S is effectively prevented. At this time, the abutment portion 2 is filled with air so that the pressure of the sacrum portion S does not reach the bottom due to the load.

Since the sacral portion is supported by the abutment portion 2, a part of the load applied to the sacral portion S is shared by the abutment portion 2, so that the load sharing by the outer peripheral portion 8 is reduced. A more uniform load distribution is achieved in the sacral portion S and its outer periphery.

Further, the outer peripheral portion 8 of the pad 1 has two left and right chambers with the contact portion 2 interposed therebetween.
a and 8b are supplied to the other hollow chamber 8 respectively.
b, 8a. That is,
As shown in FIG. 3A, in the conventional circular seat 200, when a load is unevenly applied in the ring portion, the air in the portion where the load is applied is moved, the amount of air is reduced, and the shape is greatly changed. As a result, the body pressure dispersing function at the site was reduced, and a bottom-out condition occurred.

However, in this pad 1, FIG.
As shown in (b), one hollow chamber 8a, 8
b, the air remains in the other hollow chambers 8b, 8a
The pad 1 is moved only in the hollow chambers 8a and 8b without being moved, and as a result, the movement of the air is small, so that the shape of the pad 1 is not largely changed as a whole and the body pressure dispersing function is exhibited. State is maintained. In FIG. 3B, the mat for the lateral position is used. However, the same applies to a case where the user lies only laterally without using the mat for the lateral position.

In particular, in the pad 1, the outer peripheral portion 8 has two chambers on the left and right sides of the contact portion 2 in order to effectively exert the body pressure dispersing function even when lying on the back from the back. It is. That is, when lying sideways from the back, the load is moved to the left or right.
Therefore, when the movement of the load that is frequently performed is the entire circumference of the bone protrusion, the outer peripheral portion 8 is constituted by three or more hollow chambers, and the load is applied to any part of the outer peripheral portion 8. In addition, the air movement can be restricted to maintain the shape, and the body pressure dispersing function can be maintained and exhibited.

As described above, in the present embodiment, the pad 1 is used by independently laying under the sacral portion S. In particular, in the case of the sacral portion pad 1, as shown in FIG. It is convenient to use the diaper cover C by fixing it integrally.

By using the pad 1 in this manner, the pad 1 is always arranged along the body, and the pad 1 is arranged at an appropriate position regardless of whether the patient lies sideways or along the body again. Become. Furthermore, if the pad 1 is fixed at a position corresponding to the sacral part S in the diaper cover C,
When the diaper cover C is mounted, the pad 1 is always arranged at a substantially appropriate position, and it is not necessary to adjust the position of the pad 1 every time the diaper is changed.

When the pad 1 is used by being integrally attached to the diaper cover C, the configuration shown in FIG. 5 can be adopted. That is, the pad 1 can be attached to the inside of the inner cloth 21 and the outer cloth 22 constituting the diaper cover C via an appropriate detachable member. In FIG. 5, a locking member 24 composed of a male member and a female member
Are attached to the back surface of the pad 1 and the inner surface of the cloth 22, so that the pad 1 is detachably provided. in this case,
The pad 1 can be removed from the inside of the diaper cover C as needed.

Although the pad 1 of the present embodiment is formed in a substantially quadrangular shape as a whole, the entire pad 1 is formed into a triangular shape in consideration of a feeling of fitting to the body and a fitting feeling when attached to the diaper cover C. The pad 28 may be formed in a shape. That is, as shown in FIG. 6, the outer peripheral portion 32 surrounding the contact portion 30 is formed in a triangular outer shape. In this case, the outer peripheral portion 32 may have a left-right two-chamber configuration or a three-room configuration along three sides.

Further, like the pad 1, the pad 32 can be detachably attached to the diaper cover C, and can be attached at a movable position. With this arrangement, the mounting position of the pad 1 can be changed according to the user's limb position. Therefore, even for diaper users who are expected to be deformed and contracted,
The diaper cover C is comfortable and can prevent the sacral pressure sore.

(Embodiment 2) Next, Embodiment 2 will be described with reference to FIG. In the present embodiment, a description will be given of a pad 41 that detects the bottom of a bone protrusion and allows a caregiver to recognize the bottom. FIG. 7 shows a cross section of the pad 41. The pad 41 is, like the pad 1 of the first embodiment,
It has a contact portion 42 and an outer peripheral portion 48. The contact portion 42 is a bag-like body having a hollow chamber 42a.
Are two left and right hollow chambers 48a, 48 with the contact portion 42 interposed therebetween.
b. The bag-like bodies 42, 50a, 50b are also each provided with a sealable air inlet.

Air is injected into each of the hollow chamber 42a of the contact portion 42 and the hollow chambers 48a and 48b of the outer peripheral portion 48, and has an appropriate thickness and a function of dispersing body pressure. A bottomed indicator 52 having a power supply is connected to the contact portion 42 via lead wires 54 and 56.

Lead wire 54 wired from display 52
Is directed to the bottom surface of the contact portion 42 via the display 52 provided with a light bulb 52a as a display means. Also, the other lead wire 56 similarly wired from the display 52
Is directed to the upper surface portion via the bottom surface portion of the contact portion 42. These lead wires 54 and 56 are connected to the hollow chamber 4.
It is connected to two electrodes 60 and 62 arranged inside 2a, respectively.

The upper electrode 62 is provided on the inner surface of the contact portion 42 on the side directly receiving the body load, and the lower electrode 60 is provided on the inner side of the bottom surface of the bag 44 facing the upper electrode 62. I have. That is, in the hollow chamber 42a, the electrodes 60 and 62 are vertically arranged opposite to each other, and the contact portion 42 is bent by the pressure applied by the sacral portion S, so that the upper surface portion and the bottom portion of the contact portion 42 are bent. When they are close enough to touch, they are touched.

Next, the operation and effect when the pad 41 thus formed is used will be described. FIG. 7 (b)
3 shows a cross section when the pad 41 is laid under the sacral portion S of the patient. In this figure, the sacral part S of the patient is projected downward, the abutting part 42 is deformed, and the patient comes close enough to contact the upper surface part and the bottom surface part, and the body pressure dispersing function is not maintained. . In this case, if the power supply of the display 52 is turned on, when the upper electrode 62 and the lower electrode 60 come into contact in the hollow chamber 42a,
Since the power can be supplied from the power supply, the electrodes 60, 6
2, the conduction state is established, the bottomed indicator 52 is energized, and the light bulb 52a is turned on.

By this lighting, the care giver can recognize the bottomed state of the sacral portion S, and the air filling amount in the hollow chamber 42a is insufficient, or the hollow chamber 42a and the hollow chambers 48a, 48
The pad 41 can be formed so as not to be in a bottomed state by adjusting the imbalance between the air filling amount and the air amount 8b. As a result, the pad 41 of the present embodiment can more reliably prevent the occurrence of pressure sores.

Further, even when the load distribution on the pad 41 is changed due to the change of the body position and bottoming occurs,
Since the bottoming state can be detected simultaneously with the occurrence of bottoming, the filling amount can be adjusted and the body position can be changed earlier, and the occurrence of pressure sores can be prevented by a quick response. Furthermore, if the elapsed time from the bottom detection can be displayed, a reasonable care work can be performed in consideration of the elapsed time, and the burden on the caregiver can be reduced.

The pad 41 can be used integrally with the diaper cover S or detachably provided, similarly to the pad 1 of the first embodiment.

Third Embodiment Next, a third embodiment will be described with reference to FIGS. In the present embodiment, the pad 71 which detects the pressure applied to the contact portion 72 and can adjust the air filling amount according to the pressure will be described. The structure of the pad 71 is shown in FIG. This pad 7
Reference numeral 1 is intended to prevent a sacral depressed wound as in the first embodiment, and includes a contact portion 72 and an outer peripheral portion 78. Similarly, three hollow chambers 72a, 78a, 78b are provided. have.

The pad 71 of the present embodiment is different from the pad 1 of the first embodiment in that a contact portion 72 and each of the bag-like bodies 80a and 80 are provided.
The point is that an air injection adapter 100 provided with a pressure gauge 113 and an air injection tube 110 divided into three for injecting air into each air injection port of b.

The adapter 100 has a sealable inlet 1 for introducing air into each air inlet tube 110.
12. The air inlets 90a and 90b communicating with the hollow chambers 78a and 78b are provided with air check valves 92.
a, 92b are provided so that the air injected into the hollow chambers 78a, 78b does not normally flow out. The air in the hollow chamber 72a can always move inside the adapter 100.

The pressure gauge 113 has an air pressure inside the adapter 100, that is, since the adapter 100 and the hollow chamber 72a of the contact portion 72 are actually connected to each other,
This is for detecting the air pressure of 2a (the body pressure applied to the contact portion 72). As shown in FIGS. 9A and 9B, the pressure gauge 113 is formed by using the elasticity of a spring 114 in this embodiment, and a numerical value corresponding to the air pressure is indicated by a pressure gauge 115.
Can be detected with. In this embodiment,
Although the elasticity of the spring 114 is used, the present invention is not limited to this, and air pressure detection by another mechanism can be used.

Next, the operation and effect when the pad 71 thus formed is used will be described. Air is in each hollow chamber 7
When the pad 71 is laid below the sacrum S after the air filling port 112 is sealed and the air inlet 112 is filled, the body pressure applied to the contact part 72 is indicated by the pressure gauge 115. That is, when the pressure indicated by the pressure gauge 115 is large at the time of laying, it means that the pressure contact state has occurred in the contact portion 72. For this reason, by applying the pressure to the pressure-time curve at the time of pressure sore generation, the caregiver can surely grasp the necessary information regarding postural change, and can perform appropriate and rational care.

Further, by additionally providing a device capable of monitoring and recording the air pressure of the contact portion 72, it is possible to more easily and appropriately grasp necessary information, and to easily determine the necessity of changing the body position. Thus, more appropriate and reasonable care can be provided. Further, an air injecting device is provided in the configuration of the pad 71, and an abutment portion 72 is provided from an air pressure monitor.
May be provided to automatically adjust the appropriate amount of air. Thereby, the trouble of changing the body position and the trouble of checking the air pressure can be omitted.

The pad 71 can be used integrally with the diaper cover C or detachably provided, similarly to the pad 1 of the first embodiment.

Fourth Embodiment Next, a fourth embodiment will be described with reference to FIGS. Pad 12 of the present embodiment
Reference numeral 1 denotes a sacral portion S similar to the pad 1 of the first embodiment.
This is for preventing pressure ulcer wounds of the patient, and, like the pad 1, is composed of a contact portion 122 and an outer peripheral portion 128.
And two hollow chambers. Pad 1 of the present embodiment
The difference between the pad 21 and the pad 1 is that the pad 121 is provided with flap-shaped auxiliary pad portions 130 and 132 symmetrically on a part of the upper surface of the outer peripheral portion 128.

Each of the auxiliary pad portions 130 and 132 is formed in a bag-like body filled with air, and is filled with air. The mounting bases 130a, 132a of the auxiliary pad portions 130, 132 are provided inside and outside the outer peripheral portion 128 at the mounting base portion.
132 is formed in a substantially hinge shape so that the position can be changed by folding. In this embodiment, the mounting base 1
Reference numerals 30a and 132a are formed in an elongated band shape using the same material as each bag-shaped body of the outer peripheral portion 128, and auxiliary pad portions 130 and 132 are integrated on the upper surface of the outer peripheral portion 128 via the band-shaped material. . Note that these auxiliary pad portions 130, 1
The hollow chamber 32 and the hollow chamber of the outer peripheral portion 128 are not communicated with each other.

Next, the operation and effect when such a pad 121 is used will be described. FIG. 11 shows a state in which the pad 121 is attached to the diaper cover C and used. As shown in FIG. 11, by attaching the pad 121 to the diaper cover C, even when the body position is changed from the supine position to the lateral position, the pad 121 is
You will be moved along your body. And, if the auxiliary pad portions 130 and 132 are positioned in advance toward the outside of the outer peripheral portion 128 in advance, when the prone position lies on the greater trochanter portion of the lateral sacral protruding portion of the sacral portion which is the lower side of the body when lying down. The contact can prevent the occurrence of pressure sores at this site.

In order to maintain the sitting position, the auxiliary pad portions 130 and 132 are each folded inside the outer peripheral portion 128 so as to overlap the outer peripheral portion 128 and the contact portion 122. Thus, a large load applied to the ischial tuberosity Z protruding during the sitting position can be dispersed by the double pad structure. In the present embodiment, by attaching the pad 121 to the diaper cover C, it is possible to more easily cope with such a posture change than when the pad 121 is used alone.

As described above, according to the pad 121 of this embodiment, it is possible to easily and appropriately cope with not only the supine position but also the lateral position and the sitting position. The auxiliary pad 1
30 and 132 can be provided detachably as needed. Further, in the present embodiment, the diaper cover C is provided integrally with the diaper cover C. However, even if the pad 121 is used alone, it can be easily applied to other bone protrusions around the target bone protrusion when the body position is changed. The effect that it can respond to.

Further, in the present embodiment, in addition to the sacrum portion S, the trochanter portion and the ischial tuberosity portion Z are used.
As shown in Fig. 1, in addition to the sacrum, the greater trochanter and the iliac (Fig. 1)
