DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an incubator provided with a care window in a hood for surrounding a housed child such as a premature infant.

[0002]

2. Description of the Related Art As disclosed in Japanese Utility Model Publication No. Sho 61-28592, when a hood or a front door of an incubator is opened, a child on a bed of the incubator moves out of the bed. We have previously devised a fall prevention device for an incubator that can prevent it from falling outside the incubator. According to the incubator incorporating such a fall prevention device, even if the hood or the front door is opened in order to examine the housed child on the bed or to change the diaper of the housed child, the housed child can be accommodated. Can be effectively prevented from falling from the bed to the outside of the incubator.

[0003]

On the other hand, the inventor of the present invention has proposed that nursing care windows provided on the front door of the hood of an incubator are relatively large openings for accommodated children such as premature infants. If a woman forgets to close the small door that opens and closes the groom window, she recently learned that the children on the bed of the incubator could move around and fall outside through the groom window.

[0004] The fall prevention device for an incubator disclosed in the above-mentioned Japanese Utility Model Publication No. 61-28592 has a pair of left and right recesses respectively opposed to a pair of left and right care windows. Therefore, even if this fall prevention device is incorporated in the incubator, there is a possibility that the child on the incubator bed will move around and fall out through the care window if you forget to close the small door that opens and closes the care window. Not necessarily gone.

The present invention is intended to effectively correct the above-mentioned disadvantages of the conventional incubator and fall prevention device for the incubator with a relatively simple structure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, first to fourth embodiments of the present invention will be described with reference to the drawings.

First Embodiment FIGS. 1 to 4 show a first embodiment of the present invention. In the first embodiment, the present invention is not limited to a hood having a double wall. It is applied to a single wall type incubator with a single wall.

The incubator comprises a pair of front and rear fall prevention devices 31 and 3.
The structure may be a conventionally well-known structure except that 2 is incorporated. Accordingly, the incubator includes an incubator base 1 and a transparent hood 2 covering the upper part of the incubator base 1 as shown in FIGS. A support base 3 is disposed on the incubator base 1, and a bed base 4 having a box shape and functioning as a bed base is mounted on the support base 3. Stores a mattress 5 functioning as a bed. Then, sheets (not shown) are laid on the mattress 5 as necessary, and a newborn baby (not shown) such as an immature baby can be laid on the mattress 5. Therefore, the hood 2 surrounds the newborn baby, that is, the accommodation baby.

At the front of the hood 2, there is provided a front door 6 which is opened and closed for taking in and out of a newborn baby.
A pair of substantially circular left and right cares used by a nurse or the like to insert left and right hands from the outside into the hood 2 for performing various treatments on the newborn baby housed in the hood 2 and the like. Windows 7 and 8 are provided. The hood 2 can be pivoted upward around the lower end of the rear surface as a fulcrum for taking in and out of the bed frame 4, the mattress 5, etc., and cleaning. , 8, a pair of left and right care windows 9, 10 are provided. Small doors 11 to 14 that normally close the maintenance windows 7 to 10 and open as needed are attached to the maintenance windows 7 to 10 so that they can be locked at the closed positions.

In FIG. 1, reference numerals 15 and 16 denote a pair of left and right hinge mechanisms 15 and 16 which support the front door 6 so that the front door 6 can be pivoted forward with the vicinity of the lower end as a fulcrum. Reference numerals 17 and 18 denote a pair of left and right lock mechanisms for locking the front door 6 at the return rotation position. Also,
Reference numerals 19 and 20 denote a pair of left and right operation handles which are operated to raise the right end or the left end of the support 3 so that the support 3 is inclined leftward or rightward. Is shown. Further, reference numeral 21 indicates a humidifying tank, and reference numeral 22 indicates an instrument panel of various instruments incorporated in the incubator.

The incubator shown in FIGS. 1 and 2 described above may have a conventionally known structure. As described below, a pair of front and rear fall prevention tools 31 and 32 according to the present invention are incorporated in the conventionally known incubator.

The fall prevention devices 31 and 32 may be substantially entirely made of a transparent synthetic resin such as an acrylic resin. And these fall prevention tools 31 and 32 are shown in FIGS.
As shown in FIG.
A base member 33 having a U-shape and a pair of left and right closing members 34 attached to the base member 33 are provided. Further, the base member 33 includes a substrate portion 35 extending substantially horizontally,
An upright portion 36 integrally connected to one end of the substrate portion 35 is provided. Furthermore, the upright plate portion 36 extends obliquely upward by an angle θ from one side end of the substrate portion 35 so that the vertical portion 36 forms an acute angle with the substrate portion 35.

The reason that the upright portion 36 extends in such an inclined manner is that when the hood 2 is opened and closed with the fulcrum near the lower end of the rear surface, the lower end of the front surface of the hood 2 is attached to the fall prevention device 31 on the front side. This is to prevent contact. Also, the rear-side fall-prevention device 32 does not necessarily need to extend in such an inclined manner. It is preferable to have the same structure as the fall prevention device 31 on the front side, since a pair of front and rear can be arranged by changing the direction. The angle θ formed between the substrate portion 35 and the standing plate portion 36 is about 82 ° in the illustrated embodiment. However, when the angle θ is made to be an acute angle, it is generally referred to from the viewpoint of practicality. hand,
It is preferably from 70 to 86 °, more preferably from 75 to 84 °.

As shown in FIGS. 2 to 4, the standing plate portion 36 has substantially the same shape as the lower half of the care windows 7 to 10, and is arranged substantially opposite to the lower half. A pair of left and right circular concave portions 37 are formed as missing portions or window portions. In addition, the upright portion 36 has these concave portions 3.
A pair of right and left closing members 34 of a substantially semicircular shape, which is slightly larger than these recesses 37, are mounted to be able to reciprocate and rotate so as to be substantially opposed to. In addition, as shown in FIG. 4, a pair of left and right bearing members 38 and 39, and these bearing members 38 and 39 are attached to the upright portion 36 of the closing member 34.
Screws 40 and 41 for fixing 39 to the inner surface of the standing plate portion 36
And a pair of left and right support shafts 42, 43, and coil springs 44, 45 as urging means for elastically urging the closing member 34 in the backward rotation direction.

That is, on the inner end surfaces of the bearing members 38 and 39, a substantially cylindrical concave portion 46 for inserting a half of the coil springs 44 and 45 and a support shaft formed so as to be continuous with the concave portion 46 are formed. A shaft hole (not shown) for inserting a half portion of each of the first and second coil springs 44 and 45 into which a half portion of each of the first and second coil springs 44 and 45 is inserted. 48 are provided. At the lower end of the sealing member 34, a pair of left and right pivoted support portions 49 and 50 are integrally provided to protrude. The bearing members 38, 3
9, a substantially cylindrical concave portion 51 for inserting the other half of the coil springs 44 and 45, and a concave portion 5
1 and a shaft hole (not shown) for inserting the other half of the support shafts 42 and 43, and coil springs 44 and 4 formed so as to be continuous with the concave portion 51.
5 is provided with a locking groove 53 into which the other end is inserted. Therefore, the closing member 34 is pivotally supported by the upright plate portion 36 by the pair of left and right support shafts 42 and 43 so as to be capable of reciprocating rotation. The closing member 34 is elastically urged toward the upright portion 36 by a pair of left and right coil springs 44 and 45 and normally comes into contact with the outer peripheral portion of the concave portion 37 formed in the upright portion 36. The position is held at the returned rotation position.
Therefore, the sealing member 34 normally seals the recess 37 almost completely.

The fall prevention device 31 configured as described above,
When incorporating the fall prevention devices 31 and 32 into both sides of the mattress 5 (that is, the hood 2)
(The inner side of the front wall and the inner side of the rear wall), and the substrate portion 35 of the fall prevention devices 31, 32 may be sandwiched between the bed frame 4 as a bed base and the mattress 5. Therefore, specifically, for example, the mattress 5 is lifted or temporarily taken out while the hood 2 is turned upward or the front door 6 is turned forward, and then a pair of front and rear Fall prevention tools 31, 32
Is placed on the bed 4 and then the mattress 5 is stored in the bed 4 again, and the hood 2 or the front door 6 is rotated back to the original state. When removing the fall prevention devices 31 and 32 from the incubator, the reverse operation to the above-described installation may be performed. Therefore, the fall prevention tools 31, 3
2 is simple in its structure and easy to assemble and remove from the incubator. 2 to 4
Shows the fall prevention device 31 on the front side, but the fall prevention device 32 on the rear side may have substantially the same configuration.

When the fall prevention tools 31 and 32 are incorporated in the incubator in this manner, as shown in FIG.
In FIG. 10, four sealing members 34 partially oppose each other to at least partially seal these care windows 7 to 10 from the inside. In the illustrated embodiment, the care windows 7 to 10 are opposing / sealed about 50% of their area from the inside by the fall prevention tools 31 and 32 including the enclosing member 34 and the standing plate portion 36. In the first embodiment, the area is substantially the same as the area where the care windows 7 to 10 face the recess 37. And maintenance window 7-1
In general, the area where 0 faces and is closed by the fall prevention tools 31 and 32 and the area that faces the concave portion 37 are preferably 20 to 80% from the viewpoint of practicality.
More preferably, it is 30 to 70%.

In the incubator incorporating the fall prevention tools 31 and 32 as described above, the hood 2 can be reciprocated in the vertical direction as in the conventional case. The front door 6 can be rotated forward and backward in the opposite direction by using a pair of hinge mechanisms 15 and 16 provided near the lower end thereof as a fulcrum. Further, when a nurse or the like inserts the left and right hands from the care windows 7, 8 or 9, 10, respectively, the left and right hands push the pair of left and right sealing members 34 from outside to inside. A suitable angle (for example, from the solid line position shown in FIG. 2 to the chain line position shown in FIG. 2) with the support shafts 42 and 43 as fulcrums against the elastic biasing force of the coil springs 44 and 45
(Approximately 90 °), and is held in the retracted position. In addition,
In this case, it is possible to provide a stopper (not shown) for restricting the forward rotation position of the sealing member 34 to prevent the sealing member 34 from turning too far. Therefore, a nurse or the like can perform various treatments on the newborn housed in the hood 2 in substantially the same manner as in the conventional case. Further, when a nurse or the like pulls out the left and right hands from the care windows 7, 8 or 9, 10, respectively, the sealing member 34 is rotated back around the shafts 42, 43 by the elastic biasing forces of the coil springs 44, 45. Therefore, since it is held at the return rotation position by contacting the outer peripheral portion of the concave portion 37 formed on the standing plate portion 36, it cannot be moved further in the return rotation direction.

Therefore, since the closing member 34 normally opposes and partially closes the care windows 7 to 10 from the inside thereof, even if the small doors 11 to 14 of the care windows 7 to 10 are forgotten to be closed. In addition, it is possible to prevent an accident in which the newborn baby moves in the hood 2 to get the head out of the care windows 7 to 10 or fall to the outside through the care windows 7 to 10. In addition, the standing plate portion 36 and the sealing member 3
In some cases, when the hood 2 is pivoted upward or the front door 6 is pivoted forward, the above-described Japanese Utility Model Publication No.
In the same manner as or more than the fall prevention device for an incubator disclosed in Japanese Patent No. 28592, it is possible to effectively prevent a newborn on a mattress 5 of an incubator from falling from the mattress 5 to the outside of the incubator. .

In the first embodiment, a pair of right and left coil springs 44 and 45 are provided as urging means for urging the closing member 34 in the backward rotation direction. Good.

In the above-described first to fourth embodiments, one care window is opposed by one sealing member 34.
Although the sealing is performed, it is also possible to oppose and seal with a plurality of sealing members. In this case, a plurality of sealing members may be interlocked with each other or may reciprocate individually.

In the above-described first to third embodiments, the shape of the concave portion 37 as a missing portion or a window formed in the upright portion 36 of the base member 33 is substantially semicircular or substantially rectangular. However, these missing portions or windows 37
May be an open curve such as a substantially semi-elliptical shape or a substantially trapezoidal shape, or may be a closed curve (that is, an opening) such as a substantially circular shape, a substantially elliptical shape, a substantially rectangular shape, or a substantially hexagonal shape. Then, the sealing member 34 in the first to fourth embodiments described above.
Also, like these missing portions or windows 37, they may be of various shapes.

In the first, third and fourth embodiments described above, elastic biasing means such as coil springs 44, 45 and 86 are used to move the closing member 34 back to the closing position. However, as in the case of the above-described second embodiment, a biasing unit using the weight of the sealing member 34 by its own weight may be used.

In the above-described first to third embodiments, a lock member for locking the sealing member 34 to the sealing position is provided in order to confirm that the sealing member 34 has reliably returned to the sealing position. Is also good. In this case, specifically, a lock member having a substantially U-shaped cross section is previously fitted to the upper end of the upright plate portion 36, and the closing member 34 is returned to the closing position by a biasing means by elasticity or its own weight. Then, the lock member is slid along the upper end of the upright portion 36 to a position over the upright portion 36 and the closing member 34,
What is necessary is just to lock the sealing member 34 to the standing plate part 36. Also,
When unlocking, the reverse operation may be performed.

Furthermore, in the above-described first to third embodiments, the upright portion 36 of the base member 33 is inclined by an angle θ from the lower end to the upper end with respect to the substrate portion 35, but from the lower end to the middle ( For example, the length (corresponding to the thickness of the mattress 5) may be substantially vertical, and the middle to the upper end may be inclined by the angle θ.

According to the present invention, even when a nurse or the like can insert his / her hand into the hood through the groom window, the housed child on the head of the incubator moves around by itself and moves outside through the groom window. There is no possibility of falling down, and the configuration is relatively simple.

According to the second, fourth and fifth aspects of the present invention, it is not necessary to directly attach the closing member to the hood when the closing member is incorporated into the incubator, so that the closing member is incorporated into the incubator. Operation can be simplified,
Further, the configuration can be further simplified.

According to the third aspect of the present invention,
Since the sealing member is directly attached to the hood, the structure can be made less bulky, and the number of parts can be reduced.

Further, according to the fifth aspect of the present invention, despite the fact that the fall prevention device can be incorporated in the incubator in a stable state, a plurality of types of incubators having different longitudinal distances of the hood can be provided. Can be commonly installed, and the installation operation is simple.
