Embodiment Construction

[0023] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] In the following description, many specific details are set forth in order to fully understand the present invention, but the present invention can also be implemented in other ways than those described here, so the present invention is not limited by the specific embodiments disclosed below.

[0025] As mentioned in the background technology section, using X-rays, ultrasound or laser scanning to obtain the distribution of veins and blood vessels has different degrees of damage to the human body, and the detection equipment is bulky and inconvenient to use.

[0026] In view of the above defects, the present invention provides a blood vessel image positioning device, which emits excitation light with a wavelength of 700nm to 1100n...

Abstract

A positioning device for a blood vessel image comprises an exciting light unit, a signal detector, an image processing unit and a projecting unit. The wavelength of emitted exciting light is 700 nanometers-1100 nanometers, and the exciting light unit is used for emitting detecting light to a detected part of on the surface of the human body. The signal detector is used for collecting a spatial distribution image of diffuse reflection light intensity of the detected part on the surface of the human body. The image processing unit is used for performing signal processing on the image collected by the signal detector, so that the blood vessel image is obtained and transmitted to the projecting unit in an electric signal mode. The projecting unit is used for receiving electric signals of the image processing unit and projecting the blood vessel image on the detected part on the surface of the human body. A safe light source ( such as a light-emitting diode) is used as a lighting light source for the positioning device for the blood vessel image, the human body is not hurt or little hurt, and the positioning device is compact in size, convenient to carry and capable of working continuously for a long time.

Description

[0001] This case is a divisional application based on the above-mentioned parent application, the application date of the parent application is December 2, 2011, the application number is 201110396626.5, the publication number is CN102429644A, and the name is "vascular image positioning device". technical field [0002] The invention relates to the field of medical equipment, in particular to an angiography device. Background technique [0003] Tens of millions of venipunctures are performed every day all over the world, and venipuncture requires accurate superficial vein positioning, which is currently mainly judged by the naked eyes of medical staff. But billions of people around the world have difficulty locating veins, such as children, people who are obese, and people who have lost a lot of blood or fluid. In field rescue, such as night rescue, field rescue, earthquake relief, etc., it is also difficult to accurately locate veins due to the influence of the natural envi...
