Abstract

PURPOSE:To facilitate monitoring by mounting a solid transparent body with a desired shape securely on the external surface or the internal surface of a transparent hood of an incubator in such a manner as to be tight or almost tight. CONSTITUTION:An anti-dew formation device 6 is made up of a solid transparent body formed in a disc from glass, an acrylic resin or the like with a higher transparency and fixed on the surface of an outer hood 3 in such a manner as to be tight or almost tight. This prevents outside air from entering between the surface 6b where the anti-dew formation device 6 is mounted and the surface of the outer hood 3 to cut a cold air in a room. Thus, there is no dew formation on the internal surface of the outer hood 3 to eliminate clouding thereby enabling clear observation of a newborn in the hoods 3 and 4 through this transparent anti-dew formation device 6.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is attached to the hood of an incubator to prevent condensation generated on the inner surface of the hood from making it difficult to see through the inside of the incubator. This relates to a dew condensation preventer.

[Conventional technology]

A neonatal incubator is a type of medical unit that provides a controlled environment for premature or weak or sickly newborn infants, and is constructed as shown in FIGS. 1 and 2.

That is, in the figure, 1 is an incubator, and a newborn supporter 2a
On the base 2 having a transparent plastic outer hood 3. An inner hood 4 is installed, and a pinerest 5 is placed on the newborn baby support 2a.

Since premature infants lack a self-temperature control function, the inside of the foot 3.4 of the incubator 1 is controlled by various units installed inside the base 2 to maintain an appropriate air temperature and humidity. For example, the temperature is 36-38℃ and the humidity is 8℃.
It is designed to be maintained between 0 and 85%.

Doctors and nurses constantly monitor the health condition of the newborn baby in the incubator 1 from the outside through a transparent plastic hood 3.4.

[Problems with conventional technology]

However, if the inside of the hood 3.4 of the incubator 1 is kept at high humidity, the difference between the temperature of the room where the incubator 1 is installed and the air temperature inside the inner and outer hoods 3 and 4 may cause the outer hood to Condensation begins to form on the inner surface of 3.

The phenomenon in which such condensation occurs is related to various conditions such as the room temperature where the incubator 1 is placed, the wall temperature of the outer hood 3, the thermal conductivity of the outer hood 3, and the overall heat flow. - Although it is difficult to generalize, for example, conventional hoods 3 and 4,
Since it is usually made of acrylic material with a thickness of 5 to 6M, incubator 1 equipped with such a hood 3.4 is calculated to have an internal temperature of 35°C and a humidity of 80%. The dew point is 31℃, and the temperature of the inner wall of the outer hood 3 is 31℃.
Condensation will occur below.

Further, when the temperature inside the container is 33°C and the humidity is 90%, the dew point is 31.2°C, and dew condensation occurs when the temperature of the inner wall surface of the outer hood 3 is 31.2°C or lower.

Therefore, in a certain case, assuming the general environment in which the incubator 1 is placed, if the temperature outside the incubator, that is, the temperature inside the room, is normally 25°C, condensation will occur on the inner surface of the outer hood 3. This condensation causes the outer hood 3 to fog up, making it difficult to see through the hood 3 and monitor the newborn baby in the incubator 1 from the outside.

Conventionally, the work has been to open the hoods 3 and 4 and wipe the inside surfaces each time, but this work is not only troublesome, but also by opening the hoods 3 and 4.
This poses a major problem in that the optimal controlled environment within the incubator 1 is disturbed, which adversely affects the newborn baby.

[Means for solving problems]

The present invention was made to solve the above-mentioned conventional problems, and by covering the hood in the area that requires visibility, especially the outer hood, with a transparent heat insulating material, it is possible to prevent dew condensation in that area. The purpose of this device is to provide a dew condensation preventer for incubators that prevents condensation from forming and clouding. The first invention comprises a fixing means that is attached in close contact or almost in close contact with the outer or inner surface of the incubator; A second invention comprising a fixing means attached to the outer or inner surface to form a closed space or a closed space between the hood and the hood, at least a pair of transparent plates, and between the transparent plates. Consisting of a transparent laminate consisting of a spacer provided to form a sealed space or a nearly sealed space, and a fixing means for attaching the transparent laminate to the outer surface or inner surface of the hood of the incubator or in close contact with the outer surface or inner surface of the hood of the incubator. This is in the third invention.

(Example) Hereinafter, the present invention will be explained in detail with reference to the example shown in FIGS. 1 to 5.

1 to 3, reference numeral 6 denotes a cylindrical condensation preventer, which is attached to the surface of the forward inclined wall 3a constituting the outer hood 3, and allows the interior of the incubator 1 to be seen through the outer hood 3. Set it to the size you can.

In the embodiment of the first invention, as shown in FIG. 3, the dew condensation preventer 6 is composed of a solid transparent body formed in the shape of a disk from highly transparent glass or acrylic resin. The upper surface 6a and the lower surface 6b are each formed of parallel planes. However, in the present invention, the upper and lower surfaces 6a and 6b may be formed of non-parallel planes, parallel curved surfaces with curvature, or surfaces that have a lens effect.

(A) to (E) in FIG. 3 show different embodiments for attaching this dew condensation preventer 6 to the outer hood 3 of the incubator 1, and (A) in the same figure shows condensation prevention device 6. The entire lower surface 6b of the preventer 60 is adhesively fixed with a transparent adhesive 7a, (B) in the same figure is one in which the peripheral edge of the lower surface 6b is adhesively fixed with double-sided adhesive tape 7b, and (C) in the same figure is a screw 7c. (D) in the same figure is one that is fixed by suction with an elastic adsorption member 7d attached to the peripheral edge of the lower surface 6b, and (E) in the same figure is one that is attached to the outer periphery of the dew condensation preventer 6. It is fixed by suction using the attached elastic suction member 7e.

Each of the dew condensation preventers 6 is fixed in close contact with the surface of the outer hood 3, or in a substantially close contact state. This is to prevent outside air from entering between the mounting surface 6b of the dew condensation preventer 6 and the surface of the outer hood 3. Therefore, the dew condensation preventer 6 is used as a heat insulator to prevent condensation. This is to isolate the hood in the area where the container 6 is attached from the outside air.

Therefore, the portion of the front inclined wall 3a of the outer hood 3 where the condensation preventer 6 is attached is shielded from the cold air in the room, so the temperature inside the incubator 1 is the same as that of the hood. maintained at temperature.

Therefore, since no dew condensation occurs on the inner surface of the outer hood 3 and it does not become cloudy, the newborn baby in the hoods 3 and 4 can be clearly observed through the transparent dew condensation preventer 6. In addition, in the above embodiment, the case where the dew condensation preventer 6 is attached to the outer surface of the outer hood 3 is described in detail, but for the above-mentioned reasons, the same effect can be obtained even if the dew condensation preventer 6 is attached to the inner surface of the outer hood 3. It is.

What is shown in FIG. 4 is an embodiment of the second invention, and this dew condensation preventer 8 is composed of a transparent cylindrical body with an inverted concave cross section, and a hollow portion 8a is formed inside. and,
It is attached to the outer hood 3 at the circumferential edge 8b of the opening, and the fixing means is the same as described above.

Therefore, between the outer surface of the transparent outer hood 3 of the incubator and the dew condensation preventer 8, a sealed space or a closed space 8a is formed inside, and inside the space 8a, Air, which is a poor conductor of heat, becomes trapped.

As a result, the portion of the hood on the forward-inclined wall portion 3a where the dew condensation preventer 8 is attached is shielded from the cold indoor air, and for the same reason as mentioned above, no condensation forms on the inner surface of the outer hood 3. Since there is no fogging, the newborn baby in the hoods 3 and 4 can be clearly observed through the condensation preventer 8.

Moreover, what is shown in FIG. 5 shows an embodiment of the third invention, and this dew condensation preventer 9 has a structure in which a plurality of thin see-through plates 10 are stacked in multiple stages with ring-shaped spacers 11 interposed therebetween. The space 12 formed by each transparent plate 10 and spacer 11 is a closed space or a closed space, and the inside 12 is filled with dry air.

Therefore, this dew condensation preventer 9 is installed on the forward inclined wall 3a of the outer hood 3.
The newborn baby in the hoods 3 and 4 is observed through the dew condensation preventer 9, which is attached to the outer surface of the hood 3 and 4 using the same fixing means as described above.

Here, the space 1 between the transparent plates 10 and 10 of the dew condensation preventer 9
In space 1, dry air, which is a poor conductor of heat, is arranged in multiple stages, which further improves the insulation effect.
If 2 is a closed space, it can be placed in a vacuum state and the heat insulation effect can be further improved.

In addition, in both the above embodiments, the dew condensation preventers 6 and 8
．． Although the planar shape of 9 is circular, it is needless to say that it is not limited to this shape.

〔Effect of the invention〕

Since the dew condensation preventer according to the present invention has the above-described configuration, by attaching the dew condensation preventer to the hood of the incubator, dew condensation is prevented from forming on the inner surface of the hood where the hood is attached. -There is less chance of cloudy weather. therefore,
Since the health condition of a newborn baby can be easily monitored from the outside by looking through the hood, the work of opening the hood and wiping the inside can be omitted, and the environment inside the incubator can be easily monitored by opening the hood. This has various effects such as being able to prevent disturbances.
