Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem that an assistant for lighting is necessary in a case of injection requiring lighting such as injection in a dark part in each opening part of a human being and that it is hard to light up a desirable part when using the light from outside of the syringe because shadows are formed by hands of a doctor and medical tools. <P>SOLUTION: Light is emitted form a tip of a syringe piston to pass through transparent medicinal liquid, and a peripheral part of the tip of a needle is irradiated with the light using the principle of the optical fiber. Light is emitted from the syringe itself, and the shadows of hands and the tools are eliminated, and an assistant is unnecessary. <P>COPYRIGHT: (C)2003,JPO

Description

Description: BACKGROUND OF THE INVENTION The present invention relates to a transparent material placed in a syringe cylinder using a transparent material, in which a light source is arranged at the tip of a transparent material piston, a battery is used as a power source, and a transparent material is used. By applying the principle of the optical fiber, light passes through a transparent chemical solution and irradiates a focused and strong light without a shadow on the tip of the needle. 2. Description of the Related Art Conventionally, there is no such a syringe, and when injecting into a narrow and dark affected part such as the mouth or anus, an assistant illuminates the affected part in consultation with a doctor, and the doctor performs injection. Or the doctor himself holds the lighting fixture in one hand and injects it with the other hand.These are all methods of lighting from the outside of the syringe, which is troublesome and inconvenient, such as shadows caused by the fixture. Was. SUMMARY OF THE INVENTION [0003] The present invention is intended to allow a syringe to be used to accurately visualize an affected part and to inject a target part in a narrow and dark hole of a body or at nighttime outdoors. It is to make. The purpose is to allow the doctor to perform the injection alone without the need for a lighting assistant. A lighting device is built in a transparent material piston so that light passes through a transparent chemical solution and converges light around the needle tip. The light source and the battery are integrated. BEST MODE FOR CARRYING OUT THE INVENTION Light is applied to the tip of the needle according to the principle of fiber. As described above, when an injection is performed in a narrow and dark part of a hole in a body, an injection can be performed by one person without needing an assistant for lighting. In a dark place in the field, an injection can be accurately given to an affected part without requiring any other lighting equipment. Because it is not illumination from the outside of the syringe, there is no shadow around the needle tip,
Further, since the light is converged, only that portion shines strongly and is very easy to see and convenient. The syringe of the present invention is a necessity for any hospital, military or emergency medical personnel.

Claims (1)

[Claims 1] 1. By arranging a light source at the tip of the piston of the syringe, the light passes through a transparent drug solution and is irradiated,
The needle tip and its surroundings are illuminated. 2. By expanding or converging the light of the illumination portion of the needle tip, the light can be adjusted to the periphery of the needle tip according to the length of the needle. 3. It integrates a piston, a battery, and a light source. The optical fiber syringe is as described above.
