Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a device that can be attached to a part of a transparent hood of an incubator to make it difficult to see through the inside of the incubator due to dew condensation that forms on the inner surface of the hood. This invention relates to a dew condensation preventer for incubators to prevent condensation.

[Prior Art] A neonatal incubator is a type of medical unit that provides a controlled environment for premature or weak or sickly newborn infants, as shown in Figures 1 and 2.
It has a structure as shown in the figure.

That is, in the figure, reference numeral 1 denotes an incubator, and an outer hood 3 and an inner hood 4 made of transparent plastic and having a double wall structure inside and outside are mounted on a base 2 having a newborn support 2a. A pinerest 5 is placed on top of the pine tree.

Since premature infants lack a self-temperature control function, the inside of the hoods 3 and 4 of the incubator 1 is controlled by various units installed inside the base 2 to maintain appropriate air temperature and humidity. For example, the temperature is maintained at 36 to 38 degrees Celsius and the humidity is maintained at 80 to 85%.

Doctors and nurses constantly monitor the health condition of the newborn baby in the incubator 1 from the outside through transparent plastic hoods 3 and 4.

[Problems with conventional technology]

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

This phenomenon of condensation is caused by the room temperature where the incubator 1 is placed, the wall temperature of the outer hood 3, and the temperature of the outer hood 3.
Although various conditions such as thermal conductivity and overall heat flow are involved, it cannot be generalized, but for example, conventional hoods 3 and 4 are usually made of acrylic material with a thickness of 5 to 6 mm. Therefore, in an incubator 1 equipped with such hoods 3 and 4, the dew point is calculated assuming that the temperature inside the incubator is 35℃ and the humidity is 80%.
When the temperature on the inner wall surface of the outer hood 3 is 31°C or lower, condensation will occur.

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 where the general environment in which the incubator 1 is placed is assumed, and the temperature outside the incubator, that is, the temperature inside the incubator, is normally 25°C, condensation will form 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.

Therefore, conventionally, the hoods 3 and 4 were opened each time.
The process of wiping the inside of the hood is not only troublesome, but also
Opening the incubator 1 disturbs the optimal controlled environment within the incubator 1, which poses a major problem in that it may have an adverse effect on the newborn baby.

[Means for solving problems]

The present invention was made to solve the conventional problems as described above, and by attaching it to a part of the hood that requires transparency, it prevents condensation from forming in that part and prevents fogging. The objective is to provide an anti-condensation device for incubators that can prevent condensation from occurring, and its gist is as follows:
A first invention comprising a solid transparent body attached to a portion of a transparent hood of an incubator, and a fixing means for attaching the transparent body in close contact or almost close contact with the outer surface or inner surface of the transparent hood; A hollow transparent structure having an inverted concave cross section to be attached to a portion of a transparent hood of an incubator, and a fixing means for attaching the transparent structure to the outer surface or inner surface of the transparent hood at the open end side thereof in close contact or almost close contact. and at least a pair of transparent plates attached to a part of the transparent hood of an incubator, and a spacer is interposed between the transparent plates to form a sealed space or a substantially sealed space. A third aspect of the present invention includes a transparent laminate and a fixing means for attaching the transparent laminate in close contact or substantially close contact with the outer surface or inner surface of the transparent hood.

〔Example〕

Hereinafter, the present invention will be explained in detail with reference to embodiments shown in FIGS. 1 to 5.

In FIGS. 1 to 3, reference numeral 6 denotes a cylindrical dew condensation preventer, which is attached to the outer surface of the front inclined wall portion 3a constituting the outer hood 3, so that the inside of the incubator 1 can be seen through the outer hood 3. It is set as large as possible.

In the embodiment of the first invention, this dew condensation preventer 6 has the following features:
As shown in Fig. 3, it is composed of a solid transparent body formed into a disk shape from highly transparent glass or acrylic resin, and its upper surface 6a and 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.

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

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

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

Therefore, since no dew condensation occurs on the inner surface of the outer hood 3 and it does not become cloudy, the newborn baby inside 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. 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.

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

As a result, the hood of the portion of the front inclined wall 3a where the dew condensation preventer 8 is attached is shielded from the cold indoor air, and for the same reason as above,
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 dew 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 transparent plates 10 are laminated in multiple stages with a ring-shaped spacer 11 interposed therebetween. The space 12 formed by each transparent plate 10 and the spacer 11 is a closed space or a substantially closed space, and the inside 12 is filled with dry air.

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

Here, dry air, which is a poor heat conductor, is arranged in multiple stages in the space 12 between the transparent plates 10 and 10 of the dew condensation preventer 9, so the heat insulation effect is further improved. When the space 12 is made into a closed space, it can be made into a vacuum state, and the heat insulation effect can be further improved.

In the above embodiments, the dew condensation preventers 6, 8, and 9 each have a circular planar shape, but it is needless to say that they are 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 a part of the transparent hood of the incubator, no condensation will occur on the inner surface of the hood in the attached part. , never cloudy. Therefore, doctors and nurses can easily see through the inside from the part where the anti-condensation device is installed without fogging. In addition, this condensation preventer is removable, so by attaching it to the position where you can most easily see the newborn in the incubator, you can monitor the newborn's health condition in a comfortable position. Since there is no need to make any changes to the hood, it is versatile and can be provided at a low price. Furthermore, it is possible to omit the work of opening the hood and wiping the inner surface of the hood, and it also has various effects such as being able to prevent the environment inside the incubator from being disturbed by opening the hood.
