Description

  The present invention relates to an air mattress that can effectively prevent pressure ulcers (bed slippage) that occur when a sick person or bedridden elderly person lies on the floor for a long period of time, and can support independence.

  In recent years, the number of people who are forced to go to bed in nursing homes and hospitals has been increasing with the aging of the population. In such nursing or care settings, patients lying in bed often continue to receive sustained pressure for a long time and are at risk of developing pressure ulcers. Therefore, various air mattresses (hereinafter sometimes simply referred to as air mats or mattresses) have been developed for the purpose of preventing the occurrence of such pressure sores or healing the generated pressure sores.

For example, an air mattress 40 as shown in FIG. 4 is known. In the air mattress 40, about 20 bag-shaped air cells 42 as shown in FIG. 4A are arranged side by side on a base sheet 44 as shown in FIG. 4B, and an air pump (not shown) is connected to these air cells 42. ) Is expanded by sending air of an appropriate pressure. When the air cell 42 is inflated, the central portion is substantially cylindrical, and the vicinity of the longitudinal end portion is narrowed, and a triangular fixing member 42b having a hook 42a is provided at the most distal end portion. And is configured to be fixedly mounted on the base sheet 44.
By using such an air mattress, the pressure applied to the body of a sleeping patient or the like is reduced, so that pressure ulcer is prevented or cured.

  By the way, currently available air mattresses for pressure ulcer prevention range from a thin one having a thickness of about 3 cm to a thick one having a thickness of about 20 cm. A relatively thin air mattress as shown in FIG. 4 may cause the patient to bottom. Moreover, since the body pressure dispersion effect is mainly caused by the thickness, it is necessary to increase the thickness when the body pressure dispersion effect is obtained. Therefore, as shown in Patent Document 1, assuming that the air cell is a superposition of the fixed cell and the variable cell, the lower fixed cell is always kept in an inflated state, and the upper variable cell is inflated and contracted every predetermined time ( There are things that let you do (wave). However, it has been found that when the variable cell is not inflated and contracted, it is always in an inflated state, and a disadvantage arises that it is difficult for the patient to move on the mattress when gadging up at the time of eating or drinking or turning over.

  In recent years, thin pressure distribution devices have been used for highly independent patients who do not develop pressure ulcers, rather than treating pressure ulcers after they have developed, and to prevent pressure ulcers in advance. Sometimes.

  Patients with pressure ulcers are often treated by using thick air pressure mattresses with high body pressure dispersion ability. After the pressure ulcer is completely cured, rehabilitation is performed, but it is difficult to get out of the thick mattress, so it may be changed to a thin mattress. Many.

  However, if the physical condition deteriorates while using a thin mattress and the risk of developing pressure ulcers increases, the mattress is returned to a thick mattress. This mattress replacement is a heavy burden on nurses and caregivers. There was a problem of having to own a mattress of the kind.

  The subject of the present invention was made to solve such a problem, and the air cell upper layer and the lower layer of the air cell were completely partitioned, and the air cell lower layer was evacuated as necessary. The object is to provide an air mattress whose thickness can be changed to about half when only the upper layer is filled with air.

In order to achieve the above object, the present invention takes the following technical means.
That is, the air mattress according to claim 1 is an air mattress formed by arranging a plurality of bag-shaped air cells on a base sheet in parallel. It is characterized in that it is separated into an upper layer and a lower layer by a partition plate provided horizontally to the direction end, and the thickness of the air cell is configured to be variable by the control of the air pump.

  An air mattress according to a second aspect is the air mattress according to the first aspect, wherein an air suction for adjusting an air amount in the air cell by an air pump is provided at longitudinal ends of the air cell upper layer and the lower layer. An exhaust port is provided, respectively.

  An air mattress according to a third aspect is characterized in that the air cell according to the first or second aspect has a height dimension approximately twice a width dimension in an expanded state.

According to the air mattress of the present invention, since the upper layer and the lower layer of the air cell can be completely partitioned by the partition plate, if necessary, only the upper layer can be removed by removing air from the lower layer of the air cell. Air can be left in the air. Accordingly, it is possible to change the thickness of the air mattress to about half or to return to the original thickness again depending on the purpose of use and usage conditions.
For this reason, it is convenient to switch the thickness according to the state of the patient etc. used and to raise the upper body at the time of eating and drinking, and it serves as both care and independence support with one air mattress .

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 shows a plan view of an air mattress 1 according to an embodiment of the present invention, FIG. 2 shows a structural diagram of a single air cell constituting the air mattress, (a) is a side view, and (b) is (a). FIG. 3C is a perspective view, and FIG. 3A is a sectional view of the air mattress in which both the upper layer and the lower layer of the air cell are in an expanded state, and FIG. 3B is only the upper layer. It is sectional drawing of the air mattress in an expanded state.

  As shown in FIG. 1, the air mattress 1 includes a substantially rectangular base sheet 10 and a plurality of air cells 20 arranged side by side on the base sheet 10. The air cell 20 is formed by forming a polyurethane film into a bag shape. When air is injected, the air cell 20 has a substantially rounded rectangular cross section as shown in FIG. The left and right end surfaces 24 in the longitudinal direction are formed as substantially vertical surfaces with respect to the side surfaces 23, 23. Further, triangular fixing members 25 are respectively attached to the lower portions of the left and right end surfaces 24 in the longitudinal direction, and hooks 26 are provided on the fixing members 25, respectively.

  Further, the air cell 20 is provided with a partition plate 27 that extends between the center portions on both side surfaces inside thereof and extends horizontally to the end portion in the longitudinal direction. . If the partition plate 27 is not provided, the air cell 20 is made of a polyurethane film. Therefore, when air is injected, the air cell 20 becomes substantially cylindrical, and the ratio of thickness (height) to width cannot be increased. If the air cell is thickened to prevent bottoming of the body, the width becomes wider.Therefore, the total number of air cells used for the air mattress is inevitably reduced, the area of the part that contacts the patient's body is reduced, and the contact pressure is reduced. It will be higher.

  On the other hand, if the partition plate 27 is provided, even if pressure is applied from above, the partition plate 27 does not spread in the lateral direction (width direction), so the height of the air cell 20 is increased. Even if the internal pressure of the air cell 20 is lowered and the contact pressure on the body is lowered, there is no need to worry about bottoming.

  Further, since the partition plate 27 is provided horizontally up to the longitudinal end of the air cell 20, the air cell 20 is completely partitioned into the upper layer 20a and the lower layer 20b, so that the lower layer 20b is necessary. The thickness of the air cell 20 can be changed to about half by removing the air and setting the air in only the upper layer 20a. The partition plate 27 is made of the same material as that forming the outside of the air cell 20 and is made of a polyurethane film, and is joined to the outside by high-frequency welding.

  Each of the upper layer 20a and the lower layer 20b of the air cell 20 is provided with an air intake / exhaust port 30 for injecting and discharging air therein. The air of the lower layer 20b can be easily removed. The air cell 20 implemented this time has a height of about 12 cm when both the upper layer 20a and the lower layer 20b are in an expanded state, and a height of 6 cm when the lower layer 20b contracts.

  Next, the base sheet 10 will be described. The base sheet 10 is made of nylon ox, has a non-slip process on the back surface, and is formed into a substantially rectangular shape. Equal to length. The base sheet 10 is sewn with 24 bands 12 in a row and 48 rows 2 in an Ω shape. When air is injected through the air cell 20 in this, the movement of the air cell 20 in the vertical and horizontal directions is regulated by the band 12.

  Further, a plurality of hooks are juxtaposed in the vicinity of the end of the base sheet 10 on the extension line of the left and right bands 12 arranged in the two rows. The hook 26 of the fixing member 25 provided at the left and right end portions of the air cell 20 and the hook are stopped to restrict the movement of the air cell in the longitudinal direction.

  As shown in FIG. 3 (a), the air cell is used for both the upper layer 20a and the lower layer 20b of the air cell 20 when the patient cannot turn over by himself / herself depending on the patient's condition. If the patient is in a thick mode by inflating and reducing the contact pressure on the patient to prevent pressure ulcers from occurring, and the patient can stand to some extent, the air in the lower layer 20b of the air cell 20 is removed. In order to help the patient move easily, she is trying to support herself.

As another method of use, in the thick type mode, the upper layer 20a is set to three systems, and three consecutive sequential expansions (two out of three air cells are in an expanded state, and one is repeatedly in a contracted state in sequence. The lower layer 20b may also be expanded and contracted sequentially in the same manner, and the upper layer 20a is expanded and expanded in the same manner in the same manner, so that the lower layer 20b has the same internal pressure on the head and foot sides and the waist is raised. The internal pressure may be set to prevent bottoming and maintain a good sleep posture when raising the back of the bed.
Further, the upper layer 20a can be similarly expanded and contracted in a triple manner, and the lower layer 20b can adjust the internal pressure as a whole to prevent bottoming or to distribute contact pressure.
Even in the thin mode, the upper layer 20a may be expanded and contracted sequentially.

  The air mattress according to the present invention can easily evacuate the air in the lower layer as necessary, so there is no need to prepare thick and thin mattresses. It can be said that it is suitable for eliminating the burden.
