2. Description of the Related Art Conventionally, an incubator in which a hood for enclosing a baby such as a premature baby is provided with a care window is generally used. In such an incubator,
Since the maintenance window provided on the front door of the hood is a relatively large opening for infants such as premature babies,
If a nurse forgets to close the small door that opens and closes this care window, the child laid on the mattress of this incubator may move around and fall out of the incubator through the care window. There is.

One of the inventors of the present invention is Japanese Patent Laid-Open No. 2000-2000.
As disclosed in JP-70315-A, a fall prevention device for an incubator that can prevent a child on a mattress of the incubator from falling out of the mattress through a care window that was left unclosed. I have been devising it before.
The fall prevention device for an incubator disclosed in Japanese Patent Laid-Open No. 2000-70315 basically has a base plate portion extending in a substantially horizontal direction and a base plate portion extending upward from the base plate portion in a substantially vertical direction. And a closing member that is reciprocally attached to the standing plate and is biased in the backward direction by an elastic biasing force. Then, when the fall prevention device is incorporated into the incubator, the substrate portion is sandwiched between the bed rest and the mattress, and the sealing member is at least partially opposed to the maintenance window from the inside by the sealing member. The care window is at least partially blocked from the inside. Therefore, according to the incubator incorporating such a fall-prevention device, it is possible to effectively prevent a child on the mattress from falling from the mattress to the outside of the incubator through the care window that was forgotten to be closed. When the nurse or the like inserts his / her hand through the care window, the sealing member is pushed forward by the hand against the elastic biasing force, and when the hand is pulled out from the care window, it is returned by the elastic biasing force. To do.

A pair of short side wall portions 46, 47 and a pair of engaging belt portions 62,
63 are respectively inserted into the engaging gaps formed. Therefore, the work of attaching the mattress 2 to the bed rest 1 is extremely easy. Further, in this case, since the mattress main body 41 is housed in the recess 68 surrounded by the protrusions 34 of the main body 31 of the bed rest 1, the mattress main body 41
Is securely held in position with respect to the bed rest 1.

As shown in FIG. 2, the mattress 2 includes a plurality of relatively thick core members 71 made of foamed synthetic resin such as polyurethane foam and other materials having elasticity, flexibility and flexibility, and cotton cloth or the like. It is mainly composed of a relatively thin sheet material 72 having flexibility such as woven cloth, non-woven cloth, synthetic resin sheet and artificial leather. The sheet material 72 covers the whole of the plurality of core materials 71 in a bag shape. Specifically, the mattress body 41, the pair of long side wall portions 44 and 45, and the two pairs of divided wall portions 51 to 54.
Since each of them comprises a core material 71 and a sheet material 72 covering the whole of the core material 71 in a bag shape, each of them has elasticity, flexibility and bendability. And the thin hinge portions 43, 48, 49, 55-5
8, the pair of engaging strips 62 and 63 and the pair of connecting strips 64 and 65 are made of only the sheet material 72, and thus have flexibility. The core material 71 (in other words, the mattress main body 41 and the wall portions 44, 45,
51-54) has a thickness of about 20 in the illustrated embodiment.
mm, but generally speaking from a practical point of view,
It is preferably 10 to 38 mm, more preferably 15 to 30 mm.

A bed rest with a mattress as described above is shown in FIG.
In order to be incorporated in the incubator shown in (1), the bed rest 1 of the bed rest with mattress may be mounted and arranged on the support base 5 in the incubator as conventionally known. However, in general, after the bed rest 1 is mounted on the support base 5 on the support base 5 in the incubator as is conventionally known, the mattress 2 is mounted on the bed rest 1 as described above. It is more convenient to place them.

When the bed rest with mattress is incorporated into the incubator as described above, as shown in FIG. 2, a pair of long side walls of the projecting wall portion 42 of the mattress 2 are provided inside the four maintenance windows 7-10. Since the portions 44 and 45 partially face each other, the maintenance windows 7 to 10 are provided with a pair of long side wall portions 44,
About 45% of the area is covered and blocked from inside by 45. The area in which the maintenance windows 7 to 10 are opposed and closed by the pair of long side wall portions 44 and 45 is about 50% as described above in the illustrated embodiment, but from the viewpoint of practicality. Generally speaking, it is preferably from 20 to 80%, more preferably from 30 to 70%.

Further, the widths of the long side wall portions (in other words, the wall portions facing and closing the maintenance windows 7 to 10) 44, 45 protruding upward from the upper surface of the mattress body 41 (that is, Height) is about 1 in the illustrated embodiment.

Further, as in the conventional case, the front door 6 can be rotated forward and backward with a pair of hinge mechanisms 15 and 16 provided near the lower end thereof as fulcrums, and can be rotated backward in the opposite direction. Furthermore, when a nurse or the like inserts the left and right hands through the care windows 7, 8 or 9, 10 respectively, the left and right hands push the pair of long side wall portions 44, 45 from the outside to the inside. The pair of long side wall portions 44 and 45 are elastically deformed and bent from the solid line position shown in FIG. 2 to the chain line position, and are held at the retracted position. Therefore, a nurse or the like can use the hood 4 as in the conventional case.
Various procedures can be performed on the newborn contained within. When a nurse or the like pulls out the left and right hands from the care windows 7, 8 or 9, 10 respectively, the long side wall portions 44, 45 are held in the backward rotation position by their elastic restoring force. In this case, since the front surface of the hood 4 faces the long side wall portions 44 and 45 and functions as a stopper,
Even if pushed by the child, the long side wall portions 44, 45 are prevented from moving excessively forward.

Therefore, since the long side wall portions 44, 45 (and thus the projecting wall portion 42) normally partially face and close the maintenance windows 7-10 from the inside thereof, even if the maintenance windows 7-10 are provided. Even if you forget to close the small doors 11-14,
As the newborn moves in the hood 4, these care windows 7-10
It is possible to prevent an accident in which the head is pulled out of the vehicle or the vehicle falls to the outside through the maintenance windows 7 to 10.

The mattress 2 shown in FIGS. 3 to 8 is extremely easy to handle before and after being incorporated into an incubator. That is, when the mattress 2 is removed from the bed rest 1, the reverse operation to the attachment may be performed. Moreover, the mattress 2 can be folded small as shown in FIG. In this case, the mattress main body 41 is opened after the space between the first half 61a and the second half 61b of the fastener 61 is opened.
As shown in FIG. 5, the thin hinge portion 4 is attached to the protruding wall portion 42.
It is rotated relatively outward with 3 as a fulcrum. Next, the pair of short side wall portions 46 and 47 are connected to the pair of thin hinge portions 48,
Bend inward at 49 to form a pair of dividing wall portions 51,
52 and the pair of dividing wall portions 53 and 54 are superposed on each other together with the pair of engaging belt portions 62 and 63 and the pair of connecting belt portions 64 and 65. Then, when the long side wall portions 44 are superposed on the mattress main body 41 as shown in FIG.
The mattress 2 folded in the state shown in FIG. When storing the mattress 2 in a storage box (not shown) or the like before sale, if another mattress 2 ′ that can be used as a spare is symmetrically arranged as shown in FIG. The mattresses 2, 2'can be made compact as a whole, which is convenient. Furthermore, the mattress 2 shown in FIGS. 3 to 8 has a core material 71 such as foamed polyurethane, a sheet material 72 such as cotton cloth, and fasteners 61.
Also, since it is made of thread for sewing, it can be easily washed by washing in the state shown in FIG. 5, for example. Further, the frame-shaped projecting wall portion 42 having a function of preventing falling of the housed child is integrally connected to the mattress body 41 so as not to be separated. Therefore, there is no fear that a nurse or the like forgets to incorporate the frame-shaped protruding wall portion 42 into the incubator or does not intentionally incorporate the frame-shaped protruding wall portion 42 into the incubator so that the child is laid on the mattress main body 41.

FIG. 9 shows the mattress 2 shown in FIGS.
