JPH0479966A - Filter, auxiliary light source and light ray medical treatment device - Google Patents

Abstract

PURPOSE:To diagnose the condition of a patient without causing great difference in color tone between light from a light ray medical treatment device and environmental light by providing the light ray medical treatment device with a filter and an auxiliary light source. CONSTITUTION:When a filter is used light for treatments is absorbed by the filter so that the light transmitted through the filter becomes white or such one that provides almost the same light stimulus as that caused by illumination using environmental light. When an auxiliary light source is used, light with colors complementary to the light for treatments or environmental light with complementary colors is generated and so illumination toward a child approximates one with white light or light from an environmental light source and an observer of the child receives almost the same color stimulus as that caused by white light or environmental light, as is the case when using the filter. The use of the light ray medical treatment device thus makes it possible for the observer to properly diagnose the condition of the child, with the colors of the face and skin of the child almost the same as while under environmental light.

Description

Detailed Description of the Invention (1) Industrial Application Field The present invention relates to a filter for use in combination with a phototherapy device used in the treatment of jaundice due to neonatal hyperbilirubinemia; This invention relates to an auxiliary light source and a phototherapy device equipped with the same.

(2) Prior Art A phototherapy device is used as physical therapy to treat jaundice caused by neonatal hyperbilirubinemia. In this phototherapy device, a blue-white or green fluorescent tube is generally used as a light source because blue-white or green light has a large therapeutic effect.

(3) 1M Problem to be Solved by the Invention Jaundice treatment is usually carried out by continuously irradiating light from the light source for one to several days, and during this period, the child undergoing treatment is exposed to light from a phototherapy device. Because the child is illuminated with blue-white or green light (hereinafter referred to as treatment light), the complexion and skin color of the child is exposed to normal environmental light (not receiving phototherapy).
Light from indoor lighting that is received in the general environment,
The complexion and skin color of a newborn baby, which looks significantly different from what it looks like when viewed under ambient light (hereinafter referred to as ambient light), is very important in diagnosing the baby's condition, so it is important that this cannot be observed properly. , which was a serious inconvenience when performing phototherapy.

(4) Means for solving the problem As a new means for solving the problem, the present invention provides a filter, an auxiliary light source, and a phototherapy device equipped with these, and the color tone is different when viewed in ambient light. This makes it possible to diagnose the child's condition without making any major differences.

In other words, when used as a filter for therapeutic light, the light that passes through the filter becomes light that provides color stimulation that is almost the same as the color stimulation caused by white light or ambient light, or for therapeutic light. Light with almost complementary colors (hereinafter referred to as complementary color light) or light with additive color mixture whose color stimulus is almost the same as the color stimulus of environmental light (hereinafter referred to as environmental complementary color light).

), and a phototherapy device equipped with these.

(5) Effect When the filter according to the present invention is used, the therapeutic light is absorbed by the filter that provides the above-mentioned effect, so the light that passes through the filter is similar to the color stimulation caused by white light or ambient light illumination. The light provides the same color stimulation. Therefore, the infant observer receives a color stimulus that is almost the same as the color stimulus provided by white light or ambient light. In addition, when the auxiliary light source of the present invention is used, since it generates complementary color light or environmental complementary color light to the treatment light, the illumination for the infant is close to white illumination or ambient light illumination, and the filter Similarly, the infant observer receives a color stimulus that is almost identical to that provided by white light or ambient light.

(6) Example A sheet-like filter with a color close to reddish-purple was prepared for a phototherapy device that generates green treatment light. When this filter was attached to a frame and placed to cover the light source of a phototherapy device to generate therapeutic light, the illumination was close to that of ambient light.

Therefore, if this is used when observing a baby, the baby's complexion and skin color will not be much different from when viewed under ambient light, and the baby's condition can be accurately diagnosed.

Further, a phototherapy device was placed on top of the incubator, and the sheet-shaped filter was used as a curtain to shield the phototherapy device and the incubator from light. The color of the portion of the incubator illuminated by the treatment light visible through this curtain was approximately the same color as when illuminated by ambient light. In this way, when using it as a curtain, the amount of filter to be used (
Although the light source of the phototherapy device is large, it does not cover the light source of the phototherapy device, so it can be used at all times without affecting the therapeutic effect of phototherapy, and it also prevents the color tone of the surrounding environment from changing due to the treatment light and the care of other children. It can also prevent the effects on the eyes.

Next, for the phototherapy device that generates green treatment light, a light source that generates light close to reddish-purple was created using a halogen lamp and filter. When this was attached to a phototherapy device to be used as the aforementioned auxiliary light source and mixed illumination was performed with the treatment light, the resulting illumination provided almost the same sense of color tone as illumination with ambient light. If this is used when diagnosing or treating a baby, it can be seen in the same color tone as the ambient light, so the child's condition can be diagnosed accurately, and the bright light can also be used to perform detailed treatments. It becomes like this. In order to save electricity and prevent unnecessary temperature rise,
An auxiliary light source power switch was installed so that the auxiliary light source could be used only when observing and treating infants.

(7) Effects of the Invention When the filter of the present invention is used, the light passing through the filter becomes light that provides color stimulation that is almost the same as the color stimulation caused by white light or ambient light, and the auxiliary light source of the present invention is also used. In such cases, the infant is illuminated with white lighting or lighting close to ambient lighting, so the infant can be observed without any significant difference in color or tone compared to when viewed under white light or ambient light, making it suitable for phototherapy. The child's iI without being confused by the color stimulation caused by the light.
Be able to accurately diagnose color and skin color.

In addition, when the filter is used as a curtain, it can be used at all times without affecting the therapeutic effect of phototherapy, and it also prevents the color tone of the surrounding environment from changing due to the treatment light and the eyes of caregivers of other children. It is also possible to prevent adverse effects.

Furthermore, when an auxiliary light source is used, the area can be illuminated brightly, making it possible to perform detailed treatments.

When using the filter as a curtain, it is recommended to install a window in a part of the curtain near the height of the incubator window or the bed of the neonatal treatment table to make it easier to treat the newborn. Convenient when doing so.

Several examples of the use of the present invention have been described above, but the present invention can be widely applied by providing the filter or auxiliary light source of the present invention in an incubator or neonatal treatment table, or by providing these on a stand or screen. Needless to say, it is.
