Description

Technical Field [0001] The present invention relates to a blood vessel identification system,

[0001] The present invention relates to a blood vessel identification system using IR (Irradiation Ray) and a vein irradiation method using the system, and more particularly, to an infra- It is a venous illumination system that re-examines the intensity of filtered infrared rays through image signal processing into visible light range.

(0002) In some medical procedures or treatments, it may be necessary to find veins, which are skin blood vessels, in all skin tissues throughout the patient's body. Finding these skin vessels can be very difficult, especially when there is a significant amount of subcutaneous fat.

(0003) Intravenous therapy for treatment can cause psychological anxiety not only for adults but also for children. In addition, it is often difficult for babies to find veins because it is difficult to use intravenous injection. When a nurse who is injecting finds a vein incorrectly, it may increase the fear of the patient because it repeats the injection several times.

(0004) For this reason, an intravenous infusion device using infrared rays is used to enhance the effect of intravenous injection and skin blood vessel discrimination.

(Irradiation) is a term that refers to irradiating a specific wavelength of radiation or light to a target organism, organ, tissue, cell or object.

[0005] Such a vein illuminating device using infrared rays has attracted attention in many fields because of its excellent identification performance and the advantage of no risk of exposure to infrared rays.

(0007) In the spectrum of light, the outside of red is called infrared ray, and the infrared ray is longer than visible light ray. Of these, 0.75 to 3 μm, which is the shortest wavelength, is called near-infrared ray.

(0008) In general, the illumination with the near-infrared wavelength is widely used for medical purposes in order to identify and acquire the vein of the subcutaneous layer.

(0009) However, the vein of the subcutaneous layer is covered with skin, and light is scattered due to nonuniform skin texture, so that the vein pattern can not be observed clearly in the acquired image.

Such a scattering phenomenon makes it difficult to extract a vein pattern from a captured vein image by a digital image processing method. In addition, since the vein image is input from the near side of the camera lens, blurring due to optical factors may occur, which makes the above image processing process difficult.

On the other hand, since the laser beam itself is fundamentally difficult to collectively diffuse, an angiography apparatus using a laser or a laser array as a light source has not been widely used. The laser light source can concentrate in a very narrow area and can perform uniform irradiation. When a laser is scanned, an image of the subcutaneous blood vessel is recorded and then projected in pixel form. This laser irradiation can be said to be sufficiently uniform. By irradiating the laser beam with the beam, a useful size image can be produced.

The blood vessels under the subcutaneous fat in the skin tissue can be clearly seen by the projected video image after being inputted from the camera module unit 120 and subjected to the image processing process.

The camera module unit 120 according to the present invention uses a high-sensitivity CMOS camera of 800M pixels or more and attaches a lens for adjusting the focal distance to the camera module unit 120 to improve the resolution. In addition, Respectively.

The camera module unit 120 filters and filters only the wavelength of 860 nm band outputted from the infrared irradiation laser unit 110 through the infrared ray transmitting filter, And a polarizing filter for removing reflected light.

(S104) of contrasting the input infrared rays so as to recognize the subcutaneous blood vessel (S104), amplifying the image signal (S105), and processing the image so as to recognize the subcutaneous blood vessel (S106) And an image processing step of receiving the infrared input image data from the camera module unit 120 through the image processing unit 140 and processing the images so that the subcutaneous blood vessel can be recognized.

2 is a block diagram illustrating a configuration of an IV system using infrared rays according to an exemplary embodiment of the present invention.

First, an infrared laser with a wavelength of 860 nm is output from the infrared irradiation laser unit 110 as an illumination device. In the infrared rays of the above-mentioned wavelength range, blood vessels are represented by dark lines compared to the background, thereby enabling identification of blood vessels. The infrared ray output from the infrared ray irradiation laser unit 110 passes through the condenser lens to condense an infrared laser so as to increase the illuminance of the infrared ray so that even small blood vessels projected on the skin and not possible with existing equipment can be seen.

Strobe-type power is supplied to the infrared irradiation laser unit 110.

The strobe-type power supply solves the problem of causing frequency noise due to heat generation and heat generation of the lighting apparatus due to the conventional continuous output control method. The pulse range modulation (PWM) , It means power supply of the lighting system which can improve the stability and performance of the product by increasing the lifetime without heat generation of the lighting apparatus.

(0053) This has the effect of eliminating the disadvantage that a small blood vessel can not be found due to the lowering of sharpness as a result of influences of penetration depth and reflection amount of infrared rays when irradiating infrared rays of the conventional continuous type to the skin.

The infrared light output from the infrared ray irradiation laser unit 110 is reflected by the skin of the user and enters the half mirror 6 through which the infrared ray is transmitted and the visible ray is reflected.

(Half Mirror) is a mirror that is made to reflect a part of light and transmit a part. Since the half mirror is usually half of the reflectance and transmittance, it is called a half mirror, and the camera input image is transmitted, Reflecting device.

The infrared light reflected by the skin entered through the half mirror 6 passes through the infrared ray filter 5 which transmits only infrared rays and enters the focus lens of the camera module unit 120 so that the camera module unit 120 Recognizes the image.

The image recognized by the camera module unit 120 may image the infrared image in the image processing unit 140 and may record the infrared image in the memory device of the main control unit 160. [

The image processed in the image processing unit 140 is irradiated through the image output unit 150.

The image irradiated through the image output unit 150 is visible light and includes a blue LED 15 having a wavelength of 540 to 550 nm and a green LED 14 having a wavelength of 430 to 440 nm. And a red LED 13 having a wavelength of 630 to 640 nm are irradiated onto the blue LED 15. The light emitted from the blue LED 15 passes through a half mirror 12 which transmits blue light and reflects green light, And the green LED 14 passes through the red reflecting half mirror 11 after being reflected by the half mirror 12 which reflects the green light and the green LED 14 passes through the red LED 13, Is reflected by the red reflecting half mirror 11.

The three light sources of red, green, and blue are reflected by the half mirror 8, which is reflected by the RGB reflector 10 and transmits the image of the liquid crystal through the RGB.

The image irradiated by the image output unit 150 passes through the image module 9 and is projected onto the half mirror 8 through which the image of the liquid crystal is transmitted through the RGB to form three colors of red, Combined with the light source.

The images combined by the three light sources are focused through a focusing lens 7 for focusing a visible light beam and then reflected on the half mirror 6 to display images in which blood vessels finally subjected to image processing are displayed on the skin .
