Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an incubator, and particularly to an incubator in which a newborn baby is housed in a hood and kept isolated from the outside air, when an entrance/exit door provided in the hood is opened, the newborn baby is This article relates to improvements to incubators that eliminate the effects of

This type of incubator is a medical unit that provides a controlled environment for prematurely born or weak or sickly newborns, preventing them from becoming a potential source of infectious disease or from overcoming difficulties themselves. It is used to aid in isolation from unsuitable outside air.

And many incubators are equipped with devices that allow access to the newborn so that the newborn can be helped and attended to within the incubator.

A typical device for this purpose includes an arm opening or entry/exit port in one or more of the incubator's hoods through which the newborn's caregiver can insert their hands and arms into the incubator to access the newborn. There is something attached to the side wall.

In situations such as caring for a critically ill newborn, it is preferable to provide a complete newborn entrance rather than using a type of entry/exit port with an arm opening.

This is accomplished by providing an entry/exit door in the hood.

However, inside the hood, the temperature, humidity, oxygen concentration, etc. are regulated by an air conditioning system to create the optimal environmental atmosphere for each newborn baby housed.

Therefore, if the entrance/exit door is open for a relatively short time, it will not have a negative effect on the newborn. However, if the opening time for the newborn is longer and the door is open for a longer time, outside air will flow into the hood and adjust the temperature. This disturbs the environment inside the food hood, which has been used for a long time, and has a serious negative physiological effect on the newborn baby.

SUMMARY OF THE INVENTION In view of the above, an object of the present invention is to provide a novel incubator that completely eliminates the adverse effects on a newborn baby even if the entrance door provided in the hood of the incubator is opened.

Hereinafter, the present invention will be described in detail based on illustrated embodiments.

1A and B and FIGS. 2A and B, the incubator constructed according to the present invention has air between the neonatal support 12 and the space below and above the support 12. The base body 10 is provided with three air circulation passages through which the air can circulate.

This base body 10 is equipped with various units for creating a desired environment within the incubator.

The neonatal support 12 described above consists of a pinerest support and a pinerest on which the newborn baby is placed.

The air flow passageway includes a first opening 14 and a first opening located at the head and leg ends of the base 10 and neonatal support 12.
The openings 14, 16 and 18 are elongated and have an opening 16 and a third opening 18 (clearly shown in FIG. 2B) located on the front side of the base 10 and the neonatal support 12. a narrow opening extending along three sides of the neonatal support 12;
Spaces are defined above and below 2 and freely communicate with each other, so that air can flow between these spaces.

The incubator of the present invention further includes a hood 20 that covers the base 10 and surrounds the newborn baby placed on the newborn support 12.

As shown in the figure, this hood 20 has a rectangular horizontal cross section.

The front wall of the hood 20 is provided with an entrance/exit door 22 which is movable between a closed position as shown in FIGS. 1A and B and an open position as shown in FIGS. 2A and B.

In particular, the entrance/exit door 22 is mounted so as to be pivotable about a horizontal axis, and the entrance/exit door 22 is pivoted downward when opening and upward when closing.

The hood 20 is attached to the base body 10 such that it can be raised as a whole by a pivoting action about a hinge extending along the top of the rear wall of the base body 10.

The incubator of the present invention further includes a base body 10 and a neonatal support body 1.
2 is provided with an air conditioning device for supplying conditioned air.

Briefly, the device includes an inlet, a filter, a heater, an oxygen source, a humidifier, and other components that produce conditioned air having the appropriate temperature, oxygen content, and humidity. There is.

The incubator of FIG.
6 and again below the neonatal support 12.

The apparatus is equipped with suitable blowers and ductwork so that the conditioned air can be
is forced to flow through opening 14 into hood 20 and through opening 16 into substrate 10, as shown by arrow 21 at .

Furthermore, the conditioned air is as shown in Figure 2B.
It is also sent in the direction of the opening 18.

The incubator of the present invention further has an entrance/exit door 22 as shown in FIG.
and an access door 22 for closing the opening 18 when in the closed position shown in FIGS. It is equipped with means for automatic control in response to movement.

Figures 3, 4 and 5 show in detail the manner in which conditioned air is delivered to the opening 18 and the means for closing and opening this opening 18.

The conditioned air flows through a plurality of slots 2 provided in the deck 24.
3 into the lower chamber 26 of the neonatal support 12.

Airflow through the aperture 18 is controlled by an elongated strip 28 that is movable to selectively open and close the aperture 18, and a linkage is mounted between the strip 28 and the access door 22. There is.

In particular, an elongate strip 28 of approximately the same shape and size as the aperture 18 extends along the front surface of the neonatal support 12 and is pivotable along the longitudinal end surface thereof. Attached to the end.

When the strip 28 is in the position shown in FIG. 4 and in the position shown in solid lines in FIG. Flow is blocked or only a small flow rate is allowed to flow.

When the strip 28 is moved to the position shown in dashed lines in FIG.
6, it is flowed through opening 18, as shown by arrow 30 in FIGS. 2A, B and 5.

At the same time, the conditioned air is
Circulation between substrate 10 and hood 20 continues through openings 14 and 16.

Strip 28 connects neonatal support 12 and entrance door 22.
and is controlled by a mechanism operated by the entrance/exit door 22.

In particular, when the entrance/exit door 22 is in the closed position, this door 22
Bracket 32 on door hinge 34 to which 2 is fixed
is engaged with the spring member 36, and the spring member 3
6 is moved downwardly to maintain this spring member 36 in the position shown in solid lines in FIGS. 4 and 5.

The spring member 36 is fixed at its other end to the underside 38 of the neonatal support 12.

The spring member 36 is attached to the locking piece 4 of the st-IJ knob 28.
2. The hook 40 is provided to engage with 2.

When spring member 36 is held in the position shown in FIG. 4, strip 28 is in a position to close opening 18.

When the entrance door 22 is opened and the door hinge 34 is moved to the position shown by the dashed line in FIG.
no longer engages spring member 36, so that spring member 36 can be moved to the position shown in dashed lines in FIG.

As a result of this movement, the hook 40 of the spring member 36 comes into contact with the lower surface of the locking piece 42 of the strip 28, and the strip 28 is pivoted about the hinge 44 to the position shown by the dashed line in FIG.

This causes conditioned air to flow upwardly from chamber 26 through opening 18, forming a curtain of conditioned air across the door opening.

Some of the conditioned air flowing upwardly through opening 18 flows out of the incubator as shown in FIG. It enters the main stream which circulates upwards and downwards through openings 16 .

When the access door 22 is moved to the closed position, the bracket 32 of the door hinge 34 engages the spring member 36, returning the spring member 36 to the position shown in FIG.

As spring member 36 moves downward, hook 40 is pulled downward.

The hook 40 then pulls the locking piece 42 of the strip 28 downward, moving the sleeve 1-IJ knob 28 to a position where the opening 18 is closed.

At the appropriate point of movement of the strip 28, the hook 40 and locking piece 42 are disengaged and the strip 28 is moved to the closed position under the action of gravity.

Having thus far described preferred embodiments of this invention,
It will be obvious that various changes and modifications are possible within the scope of the invention.

Since this invention has the above configuration, the entrance/exit door 2
When opening door 22 to perform treatment, etc. on a newborn in an incubator, even if the opening time of this entrance/exit door 22 becomes longer,
Due to the regulated air flow emitted like a curtain from the opening 18, the inside of the incubator does not come into direct contact with the outside air, thus reducing the impact on the newborn by opening the entrance/exit door 22, and preventing vital physiological changes for the newborn. There are various effects such as having no negative impact.
