Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cover for an incubator hood used when treating and / or preventing a disease using a phototherapy device for a newborn or the like housed in the hood of the incubator.
[0002]
[Prior art]
FIG. 3 shows a state where the phototherapy device 31 is placed on the top surface 25 of the transparent hood 23 of the incubator 21. The phototherapy device 31 particularly emits light in the vicinity of a specific wavelength so that, for example, treatment and / or prevention of jaundice can be effectively performed on a newborn housed in the transparent hood 23 of the incubator 21. In many cases, light containing a large amount is irradiated.
[0003]
This phototherapy device 31 uses, for example, five BG (blue-green) fluorescent tubes that emit green light with a particularly large amount of light having a wavelength near 520 nm and a little light having a wavelength near 440 nm. . When these BG fluorescent tubes are turned on, light having special spectral characteristics as shown in FIG. 4 is obtained.
[0004]
In addition, the applicant of the present application has four BG-type fluorescent tubes that emit a green light with a particularly large amount of light having a wavelength near 520 nm and a little light having a wavelength near 440 nm at the time of lighting, and a wavelength near 610 nm at the time of lighting. A single P-type (pink) fluorescent tube that emits a lot of light and pinkish light (light of a color that is almost complementary to the light emitted from the BG-type fluorescent tube) is simultaneously turned on to mix light Filed as Japanese Patent Application No. 8-69305 for a phototherapy device capable of obtaining almost white light.
[0005]
[Problems to be solved by the invention]
When treating and / or preventing jaundice for a newborn or the like, it is important to observe the skin color of the newborn or the like in order to confirm the effect. However, if the phototherapy device is used, the skin color of a newborn or the like looks green due to the green light emitted from the phototherapy device, and the true skin color cannot be observed accurately. For this reason, after turning off the fluorescent tube of the phototherapy device, the color of the skin of a newborn or the like was observed.
[0006]
However, since light having special spectral characteristics has a strong stimulus to vision, an afterimage of a complementary color corresponding to the color of the light is generated in the retina of the observer. Therefore, even if the fluorescent tube of the phototherapy device is turned off, the observer cannot accurately observe the true skin color of a newborn until the afterimage disappears from the observer's retina.
[0007]
Furthermore, light having a strong visual stimulus emitted from the phototherapy device spreads to a considerable area in the room where the phototherapy device is used, and fatigues the eyes of nurses and doctors working in the room.
[0008]
On the other hand, in the phototherapy device of Japanese Patent Application No. 8-69305, it is possible to accurately observe the color of the skin of a newborn baby even when the fluorescent tube of the phototherapy device is turned on. However, in this phototherapy device, when the P-type fluorescent tube deteriorates, it becomes impossible to accurately observe the true skin color of a newborn baby. Therefore, not only the BG-type fluorescent tube but also the P-type fluorescent tube is regularly used. Maintenance inspection and replacement are required. In addition, since the fluorescent tubes with special spectral characteristics are extremely small and expensive compared with general fluorescent tubes, there are a plurality of types of fluorescent tubes with special spectral characteristics, such as BG type fluorescent tubes and P type fluorescent tubes. The required phototherapy device of Japanese Patent Application No. 8-69305 was expensive.
[0009]
[Means for Solving the Problems]
In order to solve the above-described problems, the incubator cover for an incubator according to the present invention has a relatively low first light transmittance for phototherapy, and a second light having a complementary color relationship with the first light. Is made of a translucent material having a relatively high transmittance, and is provided with openings for allowing the first and second light to pass therethrough.
[0010]
Moreover, it is desirable that the translucent material has flexibility, and a notch is provided on the surface facing the opening / closing portion provided in the hood of the incubator.
[0011]
Further, the first light may include light having a wavelength near 520 nm, the light having a wavelength near 440 nm, and the second light may be light having a wavelength near 610 nm. [0012]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing one use state of a hood cover 1 of an incubator according to the present invention. The hood 23 of the incubator 21 is provided with a door 27 for taking in and out newborns and the like, and a nurse or the like puts his hand in the hood 23 without opening the door 27 and is accommodated. A maintenance window (not shown) that can be opened and closed is provided on the wall surface of the door 27 and the hood 23 so that various treatments can be performed on a newborn baby.
[0013]
The cover 1 is formed in a substantially similar shape to the hood 23 of the incubator 21 as a whole by a sheet 3 made of a flexible synthetic resin such as vinyl resin. However, the cover 1 is formed in a substantially cross shape when deployed in a plane around the upper surface 5 corresponding to the top surface 25 of the hood 23 of the incubator 21. The front, rear, left and right surfaces 9, 11, 13, 15 facing the wall surfaces can be turned separately. Then, when the cover 1 is attached to the hood 23 of the incubator 21, the adjacent surfaces 9, 11, 13, and 15 are the locking members 17 so that the front, rear, left and right surfaces 9, 11, 13, and 15 are not turned. (For example, Velcro (trademark)). A locking member 17 is also provided on the upper surface 5 of the cover 1.
[0014]
On the upper surface 5 of the cover 1, an opening 7 for passing light from the phototherapy device 31 is formed. The phototherapy device 31 includes, for example, a plurality of BG type fluorescent tubes as a light source, and most includes light having a wavelength near 520 nm and secondly contains light having a wavelength near 440 nm. Since the light emitted from the phototherapy device 31 is irradiated from the opening 7 of the cover 1 into the transparent hood 23 with almost no attenuation, it is accommodated in the hood 23 even if the hood 23 is covered with the cover 1. The phototherapy device 31 can effectively perform treatment and / or prevention of, for example, jaundice in a newborn baby. On the other hand, the cover 1 has translucency, but transmits more light having a wavelength near 610 nm corresponding to a pinkish color that is substantially complementary to the color of light emitted from the phototherapy device 31. . Accordingly, when light emitted from the phototherapy device 31 and reflected by a newborn or the like in the hood 23 passes through the cover 1 from the hood 23 and travels to the outside, light having a wavelength near 610 nm is included in this light. Is transmitted through the cover 1 without much attenuation, but light of other wavelengths is attenuated when passing through the cover 1.
[0015]
That is, the intensity of light having wavelengths near 520 nm and 440 nm that are frequently emitted from the phototherapy device 31 decreases when the light passes through the cover 1. Then, due to the balance between the light having a wavelength of about 610 nm, the intensity of which does not decrease much when passing through the cover 1, and the light having a wavelength of about 520 nm and a wavelength of about 440 nm, the intensity of which decreases, It looks achromatic (white).
[0016]
Further, the color of the cover 1 itself looks transparent because the light traveling from the cover 1 to the outside is achromatic (white). Therefore, it is possible to accurately observe the color of the skin of a newborn or the like housed in the hood 23 in order to treat and / or prevent jaundice while using the phototherapy device 31.
[0017]
FIG. 2 is a perspective view showing another use state of the cover 1 shown in FIG. As shown in FIG. 2, by engaging the locking member 17 on the front surface 9 of the cover 1 with the locking member 17 on the upper surface 5, the front surface 9 can be held up. Thereby, when opening the door 27 and taking in and out a newborn baby, the front surface 9 does not get in the way.
[0018]
As mentioned above, although the Example of this invention was described, the cover for food | hoods of the incubator by this invention can take various aspects other than an Example.
[0019]
For example, in the embodiment shown in FIG. 2, when the door 27 provided on the hood 23 of the incubator 21 is opened and closed, the surface 9 facing the door 27 can be turned up. If the opening / closing part provided on the hood of the incubator is small, such as a care window, you can pass your hand through the surface facing the care window. One notch may be provided.
[0020]
Also, if the phototherapy device does not use the BG type fluorescent tube described in the embodiment, and uses a BW type (blue white) fluorescent tube that emits light blue with a particularly large amount of light having a wavelength near 470 nm when it is turned on. As the cover, a cover having a reddish color by transmitting a particularly large amount of light having a wavelength of about 660 nm and transmitting a large amount of light having a wavelength of about 440 nm or 550 nm may be used.
[0021]
Further, although the phototherapy device has been described as being used for the treatment and / or prevention of jaundice, it is possible to treat and / or prevent various diseases other than jaundice using the phototherapy device. Therefore, the wavelength characteristics of the light emitted from the phototherapy device may differ depending on each disease, but the color of the cover at that time is complementary to the color of the light emitted from the phototherapy device. Select a color.
[0022]
【The invention's effect】
The cover for the hood of the incubator according to the present invention is made of a translucent material having a relatively high transmittance of the second light having a complementary color relationship with the first light emitted from the phototherapy device. Thereby, when the light emitted from the phototherapy device passes through the cover from the inside of the hood and goes to the outside, the intensity of the first light is reduced, and the second color that is in a complementary color relationship with the first light. The intensity of the light does not decrease so much, and the intensity of the first light and the second light is balanced and looks almost achromatic (white). Therefore, the true skin color of a newborn or the like housed in a hood can be accurately observed while using a phototherapy device having only a light source having special spectral characteristics for phototherapy.
[0023]
The cover is provided with an opening for allowing light to pass therethrough, and light emitted from the phototherapy device is irradiated from the opening into the hood with little attenuation. For this reason, treatment and / or prevention of a disease can be effectively performed by a phototherapy device.
[0024]
In addition, since the light going outward from the cover appears almost achromatic, the color of the entire room is not affected by the color of the light emitted from the phototherapy device, preventing the eyes of nurses and doctors working in this room. it can.
[0025]
In addition, the light therapy device is capable of observing the true skin color of newborns and the like accurately while using the phototherapy device with the light going outward from the cover appearing almost achromatic. It is only necessary to provide a light source that emits light for use, and it is not necessary to provide light sources having a plurality of types of special spectral characteristics, so that the cost of using the phototherapy device can be reduced.
[0026]
Moreover, since the cover made of a light-transmitting material having flexibility can be easily attached to and detached from the hood of the incubator, it can respond quickly according to the use / non-use of the phototherapy device.
[0027]
In addition, since the cover can be folded and stored when not in use, it is not disturbed even if stored near a phototherapy device or an incubator.
[0028]
Furthermore, this cover is provided with notches on both sides of the surface facing the opening / closing part provided in the hood of the incubator. Therefore, even if the cover is not removed from the hood, the inside of the hood can be accessed through the opening / closing portion only by turning the surface facing the opening / closing portion, so that a treatment for a newborn or the like housed in the hood can be performed quickly. be able to.
[0029]
Further, when the first light has the largest amount of light having a wavelength of about 520 nm, the second largest amount of light has a wavelength of about 440 nm, and the second light has a wavelength of about 610 nm, the hood In addition to effectively treating and / or preventing jaundice for a newborn housed therein, it is possible to accurately observe the true skin color of the newborn, etc. Alternatively, the prevention effect can be accurately grasped.
