Description of the invention (1) The present invention relates to the identification of the position of blood vessels-on the skin when injections or blood are drawn, etc. Detecting device for blood vessels used. K, there are JP 49-42182, JP 60-1080 4 3, JP 7- 2 5 58 4 7 and JP 2 0 0 0-3 1 6 866 Gazettes and the like disclose devices for exploring the position of a patient's blood vessels using M. Those disclosed in JP-A-49-42182 and JP-A-60-108043 both send sound waves into the body through Pi Guang, detect the position of blood vessels from their reflected sounds, and use markers. Mark this part. However, as disclosed in Japanese Patent Application Laid-Open No. 7-255847, the light is irradiated to the skin to receive the reflected light, and the test section determines whether the amount of light is below a preset threshold value. When the threshold is M, the display section The indicator light will light * to inform the presence of blood vessels at this location. Furthermore, Japanese Patent Application Laid-Open No. 2000- 3 1 686 6 discloses that the human body irradiates infrared rays to the human body, visually reflects the reflected light, and discriminates the black part of the body as the location where blood vessels exist. However, the device for detecting the position of a blood vessel using M described in JP 49-4218 2, JP 60-108043, and JP 7- 2 5 584 7 does not only need to generate a certain sound or light At the same time, it is necessary to convert the reflected sound or light reflected from the human body into an electrical signal at the same time, and determine the position of the blood vessel by a certain method, and then output the determination result through an output device such as a display device. Because of this, the entire device becomes large and cannot be easily moved, so there are problems such as lack of widespread applicability and immediate response. In this regard, the person described in JP-A-2000-316866 does not require an output device because it emits infrared light to the human body and visually reflects the reflected light.-This paper size applies the Chinese National Standard (CNS) A4 standard (210 X 297 mm) (Please read the notes on the back before filling out this page)

When applying for the invention according to item 1 of the scope of patent application, it is because: a light-shielding tube with an M-contact abutment is formed on the front end side thereof, and a light-shielding tube with an eye-contact part is formed on the base end side; The light-emitting member surrounding the light-shielding tube to irradiate light to the skin; K constitutes a blood vessel detection device, and therefore, the light-emitting member is made in a state where the front edge portion of the light-shielding tube abuts the target portion of human or animal skin Luminescence, this luminescence penetrates into the muscle through the skin to cause random reflection and diffusion, and part of it becomes reflected light and returns to the shading tube. Therefore, by placing your eyes in the eye-shielding tube, you can clearly discern the reflected light in the state of external light. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, the reflected light from the location of blood vessels with thick blood vessels is weaker than the reflected light from the muscle parts without thick blood vessels, because the position of blood vessels under the skin will be lower than others Partially black, which can confirm the existence of blood vessels. Therefore, when the skin-contacting part of the light-shielding tube is moved on the skin temple of the target position of the human body or animal, and the inside of the light-shielding tube is viewed from the eye-connecting part for visual observation, the blood vessels suitable for treatment can be easily explored. _ 2 8-This paper size is in accordance with Chinese National Standard (CNS) A4 (210 X 297 mm) 1238727 A7 B7 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 5. Description of the invention (2 6) A small device equipped with a light-shielding tube and light-emitting components arranged around it is convenient to carry, so it can be eliminated. Large-scale equipment must allow patients to go to the detection device. It lacks the tradition of wide application and immediate response. The shortcomings of the device can easily identify the position of the blood vessel regardless of the place where it is needed, especially in emergency or places where commercial power cannot be easily obtained, etc., which can be effectively used. According to the invention of claim 2 in the scope of patent application, since the lens is provided in the eye contact portion, the vision can be adjusted because the lens is provided, so that the position of the blood vessel can be detected more reliably. According to the invention in the third scope of the patent application, since the inside of the light-shielding tube is viewed through a calender, it is easy to adjust the contrast of the field of view, it can be K-contrast, it is easy to distinguish the state of blood vessels, and it is easy to explore the position of blood vessels. The invention of the fourth scope of the patent application is the blood vessel detection device according to any one of the first to the third scope of the patent scope, wherein an outer cylinder surrounding the light-shielding cylinder is provided, and the outer cylinder and the light-shielding cylinder are provided.
