Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an incubator hood, and more particularly to an incubator hood that prevents fogging due to dew condensation on the inner wall surface of the transparent hood.

[Conventional technology]

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. Note that the features of the hood according to the present invention are also added to FIGS. 1 and 2, but since the other structures are the same as the conventional one, the following description will be made based on the same figures. A conventional incubator will be explained.

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

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, when the inside of the hoods 3 and 4 of the incubator 1 are 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 causes Condensation begins to form on the inner wall 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 the thermal conductivity of the Since it is made of acrylic material, the incubator 1 equipped with such hoods 3 and 4 has a dew point of 31°C when the temperature inside the incubator is 35°C and the humidity is 80%. Condensation will occur when the temperature of the inner wall surface of the outer hood 3 is below 31°C.

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 outside temperature, that is, the indoor temperature is normally 25°C, condensation will occur on the inner wall surface of the outer hood 3. begins to occur. 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]

This invention was developed to solve the above-mentioned conventional problems, and prevents fogging of parts of the hood that require transparent viewing due to dew condensation on the inner wall of the hood. The purpose of this is to make the thickness of a part of the front wall or top wall of the transparent hood of the incubator, including the front sloped wall part, thicker than the thickness of other parts. The incubator hood is characterized by:

〔Example〕

Hereinafter, the present invention will be explained in detail with reference to embodiments shown in FIGS. 1 to 3. Note that FIG. 1 is a perspective view of an incubator equipped with a hood according to the present invention, FIG. 2 is a longitudinal cross-sectional view of the same, and FIG. 3 is a cross-sectional view of a hood according to another embodiment. In the drawings, members that are the same as those in the conventional system are indicated by the same reference numerals.

In FIGS. 1 and 2, reference numeral 3 denotes an outer hood made of transparent acrylic, which has a housing shape and is integrally formed as a whole.

Reference numeral 5 denotes a thick wall portion having a wing-like cross section formed in a portion of the front inclined wall portion 3a of the outer hood 3. The thickness of the thick wall portion 5 is larger than that of other portions. The size is set such that the inside of the incubator 1 can be seen through the portion 5.

In the illustrated embodiment, the cross-sectional shape of the thick portion 5 is a plane in which the outer surface 5a and the inner surface 5b are not parallel, but the cross-sectional shape may be a plane in which the inner and outer surfaces 5a and 5b are parallel, or a parallel plane with a curvature. They may each be formed of a curved surface or a surface having a lens effect. In the embodiments shown in FIGS. 1 and 2, the thick portion 5 is configured to bulge outward from the outer hood 3, but in the present invention, as shown in FIG. , the thick portion 5 may be configured to bulge inward of the outer hood 3. Note that the thickness H of the thick portion 5 in this case is larger than the thickness h of the other portions, as in the embodiment described above.

Further, the location where this thick portion 5 is formed is not limited to the front inclined wall portion 3a of the outer hood 3 as shown in the above embodiment,
If the incubator 1 is installed at a relatively low position, it may be formed on the top wall 3b, or alternatively, the incubator 1
It may be formed on the front vertical wall part where a specific part of the body of the newborn baby resting inside, such as a surgical site, can be clearly seen.

Therefore, the inner surface 5b of the hood, which is the thick wall portion 5 of the front inclined wall 3a of the outer hood 3, has a large heat insulating effect and is shielded from the cold air in the room. The temperature will be maintained at approximately the same temperature as the internal temperature.

Therefore, even if dew condensation occurs on the inner wall surface of the parts other than the thick part 5, no condensation will occur in the part of the thick part 5 and the hood will not become cloudy. Newborns within 3 and 4 can be clearly observed.

In addition, in the present invention, the inner wall surface 5b of the thick portion 5
If a hydrophilic or hygroscopic substance is applied to the surface to form a coating, or a film made of such a substance is attached, the anti-fogging effect will be even greater.

[Effect of idea]

As described above, the incubator hood according to the present invention has the following features:
Since the transparent hood of the incubator has a structure in which a part of the front wall or top wall including the front inclined wall is made thicker than other parts, the inner wall surface of the hood in this thicker part No condensation and no clouding. Therefore, doctors and nurses can easily see through the inside of the transparent hood from this part where no fogging occurs, and the thicker part allows them to see the newborn in the incubator. Since it is located in the most visible position, the health condition of the newborn can be easily monitored in a comfortable position.

In addition, it is possible to omit the work of opening the hood and wiping the inner wall surface, and it also has various effects such as being able to prevent the environment inside the incubator from being disturbed by opening the hood. be.
