Problems solved by technology

[0002] Venipuncture is one of the very common ways for medical staff to rescue and relieve patients' diseases. Tens of millions of venipunctures are needed every day in the world. At present, the positioning of venipuncture basically relies on the naked eyes of medical staff combined with personal However, for some special situations, such as obese people, children, people with darker skin, people with long-term venipuncture, etc., there are certain difficulties in performing venipuncture
[0003] In order to solve the above-mentioned problems, those skilled in the art are also constantly trying and improving, such as through X-ray or ultrasonic technology, but the above-mentioned solutions have relatively large radiation to the human body to a certain extent, and are generally not recommended. , there are also related patent introductions in the prior art, for example, the patent number is 201220325995.5, and the name is a blood vessel detector. The technical solution disclosed in the patent is to include an information collection box connected to a mobile phone or a laptop computer. The information The acquisition box is an M-mode processing board and a dual-channel quadrature demodulator that is connected to it in communication. The power output end of the mobile phone or laptop is electrically connected to the M-mode processing board through a transformer, and the dual-channel quadrature demodulator is connected to the M-mode processing board. 4MHz probe communication connection
Although the purpose of this technical solution is also to achieve accurate positioning of blood vessels, it is mainly applicable to blood vessel positioning in hemodialysis operations. For ordinary venipuncture, the above technical solution is not applicable
The applicant's prior patent application, patent number 201120496584.8, discloses a blood vessel image positioning device. The problem with this technical solution is that the positioning device cannot realize blood vessel information in deeper parts. , the hair will produce a shadow on the skin, which is a very strong source of image interference; in addition, after the too strong illumination light is reflected on the skin, it will cause the sensor to saturate and cause image distortion after entering the sensor, so the brightness of the reflected light source It cannot be too strong, which leads to limited penetrating ability of reflected light and cannot display deeper vascular tissue; therefore, a new positioning device is urgently needed to solve the above technical problems

Embodiment 1

[0023] see figure 1 , a blood vessel image positioning system, the blood vessel image positioning system includes a blood vessel image enhancement device 1 and an image projection device 2 used in conjunction with the enhancement device 1, the infrared transmission light emitted by the enhancement device 1 passes through the measured part of the human body surface After being received by the image projection device 2 and image processed, the in-situ imaging is performed on the surface of the skin of the measured part of the human body. The blood vessel image positioning system clearly presents the blood vessel part and the non-vascular part on the skin surface according to the skin color of the measured person. s color.

Embodiment 2

[0025] see figure 1 , as an improvement of the present invention, the enhancement device 1 includes a light emitting unit 101 and a driving unit 102 that drives the light emitting unit to emit light, the wavelength of light emitted by the light emitting unit 101 is 730 nm to 990 nm, preferably 730 nm -780 nanometers, 820-880 nanometers, 920-980 nanometers, and further preferably 760 nanometers, 850 nanometers, 960 nanometers, etc., because the transmitted light in this range is less absorbed by human tissues, and the transmitted light passing through the measured part is less Therefore, more information on the measured parts can be collected, and the definition of images can be further enhanced by multiple wavelengths. The driving unit 102 includes a power supply and a driving circuit connecting the power supply and the light emitting unit. After the transmitted light of the above-mentioned wavelength passes through the measured part of the human body surface, it is received b...

Embodiment 3

[0027] see figure 2 , as an improvement of the present invention, the enhancement device 1 further includes an inductive switching circuit 106 for detecting whether the area near the light emitting window is covered. It is mainly used to detect the area covered by the light emitting window attachment. Only when it detects that the area near the infrared light emitting window is covered, the LED switch is turned on to make it glow, thereby achieving the purpose of saving battery power. The rest of the structures and advantages are exactly the same as in Embodiment 1.

Abstract

The invention relates to a blood vessel image locating system which comprises a blood vessel image enhancing device and an image projection device matched with the enhancing device in use. Transmission light emitted by the enhancing device penetrates through the portion to be tested on the surface of the human body and is received by the image projection device, and after an image is processed, in-site imaging is conducted on the surface of the skin of the portion to be tested of the human body. The enhancing device comprises a light emitting unit and a driving unit driving the light emitting unit to emit light. Firstly, the blood vessel image locating system has the function that blood vessel in-site imaging of the portion to be tested is achieved through a transmission-type light source, the technical problems which reflected light imaging can not solve in the prior art are solved; secondly, the blood vessel image locating system further offers the mode that the transmission-type light source is combined with a reflection-type light source, the function of blood vessel in-site imaging of the portion to be tested is achieved, a transmission type and a reflection type are combined, the function of skin in-site imaging is greatly enhanced, and the blood vessel image locating system is wider in the range of application.
