In particular, in the case of facial cosmetic treatment is very high risk of side effects due to the wrong procedure, it is very important to detect the exact position of the blood vessel in order to prevent the wrong procedure.

Background Art A method of illuminating the skin using a light source corresponding to ultraviolet rays from infrared rays, filtering reflected or transmitted light using a filter having a narrow transmission area, and imaging using a goggles or a projector using various detectors is known. In addition, light in the near-infrared region that best penetrates the skin and has the highest absorption of blood is known as the most efficient light source. Intensifier tubes, CCDs, CMOS, and the like are used as detectors.

In addition, the device according to the prior art as described above is difficult to grasp the capillary blood vessels because it displays only a full-size image, and has the disadvantage of providing only a monochrome image.

In contrast, Patent Document 1 discloses that an infrared light source 111 is fixed to an inner surface of a dome-shaped support 112, and an optical zoom lens 115, an infrared transmission filter 116, and a camera 117 are disposed on an upper portion of the dome-shaped support 112. Subcutaneous vascular detection imaging device 110 is described.

However, since the subcutaneous blood vessel detection imaging apparatus uses only an infrared light source fixed in the dome-shaped support, it is difficult to irradiate light strongly to the skin at a short distance, and there is a problem that light is difficult to penetrate deeply into the skin. In addition, since the infrared light source is fixed in the dome-shaped support, it is difficult to adjust the angle at which light is irradiated, so that it is difficult to suppress diffuse reflection occurring on the surface of the skin, thereby increasing the noise of the acquired image. There is a problem.

In addition, the conventional subcutaneous blood vessel detection device has a problem that it is difficult to perform the subcutaneous blood vessel detection for various body parts (especially nose, ear, etc.) due to the structure of the light source located inside the support.

2 is a system diagram of a subcutaneous blood vessel detection imaging apparatus of the present invention. The subcutaneous blood vessel detection imaging apparatus of the present invention includes a first light source unit 10, a second light source unit 20, an image processor 30, and an image display unit 40.

The first light source unit 10 of the subcutaneous blood vessel detection imaging apparatus of the present invention includes a support and an infrared light source arranged on one inner surface of the support. The support may be a domed support having a shape in which a part of a sphere is cut out as shown in FIG. 1, and an infrared light source such as an infrared LED arranged in a circumferential direction may be arranged on an inner surface of the domed support. However, the shape of the support may be any shape as long as the shape of the infrared light source can be arranged on the inner surface to irradiate infrared rays with the skin.

The second light source unit 20 of the subcutaneous blood vessel detection imaging apparatus of the present invention includes a portable second light source unit body 21 and a second infrared light source 22 arranged on one inner surface of the second light source unit body. The second infrared light source 22 of the second light source unit is arranged on one inner surface of the portable second light source body 21, and the operator can carry the second light source body to irradiate infrared light at a desired distance at a desired position. . That is, the subcutaneous blood vessel detection imaging apparatus of the present invention can more accurately set the position and distance to which light is irradiated, compared to the conventional subcutaneous blood vessel detection imaging apparatus in which infrared light is fixed to a support, and accordingly, a higher quality subcutaneous Blood vessel detection images can be obtained.

3 shows an embodiment of the second light source unit of the present invention. The cross section of the second light source body 21 may have a shape in which at least one surface is open. For example, the second light source body 21 includes a first body 23, a second body 24, and a third body 25, wherein the first body 23 is the third body 25. ) Is disposed at one end, and the second body 24 may have a shape disposed at the other end of the third body 25. A shape in which the first to third bodies are connected may be a 'c' shape as shown in FIG. 3, a 'u' shape in which the third body is formed into a curved surface, and a length of the third body is defined. It may be a 'V' shape formed short, the 'b' shape formed a short length of the third body and the angle formed by the cross section of the first body and the second body approximately 90 degrees. The shape in which the first to third bodies are connected is not limited to the shape as described above, and may have various shapes in which at least one surface is open.

In the subcutaneous blood vessel detection imaging apparatus of the present invention, the cross section of the body of the second light source unit may have an open shape such that at least one surface thereof is open, thereby allowing the operator to easily irradiate the skin with light and to perform a desired procedure. For example, the operator carries the second light source body in one hand to irradiate the skin with light and simultaneously forms an open surface in the second light source body when performing the procedure using the treatment tool with the other hand. Through the irradiation of light at a more near distance, it will be possible to move the instrument freely through the open surface.

The second infrared light source of the second light source unit is arranged on one surface of at least one body of the first to third bodies of the second light source unit body, and is not limited to the position of the arranged surface and the number of the arranged surfaces. For example, the infrared light source may be arranged on one surface of the first body and the second body, may be arranged on one surface of the third body, may be arranged on one surface of the first body to the third body.

4A and 4B show another embodiment of the second light source unit of the present invention. The second light source body 21 may have a rod shape, which may be in the shape of a cylinder, square pillar, triangular pillar or similar polygonal pillar. The second infrared light source included in the second light source unit 22 may be disposed on the front surface or at least one side of the second light source body. 4A shows an embodiment in which a second light source unit is formed on the entire surface of the second light source unit body, and an arrow indicates a direction of irradiation of light. 4B illustrates an embodiment in which a second light source unit is formed on one side of the second light source unit body, and an arrow indicates an irradiation direction of light. The rod-shaped second light source body may be inserted into the study of the subject. The study of the subject refers to a part of the body which is formed in the form of a hole, such as a nostril and a pore. It is preferable that the 2nd light source part body which has a rod shape is 5 mm or less in diameter, More preferably, it is 3 mm or less in diameter. For example, the subcutaneous blood vessel detection imaging apparatus of the present embodiment can irradiate infrared rays from the inside of the nose or ear of the subject, and thus, the blood vessels inside the body can be identified, and thus the conventional subcutaneous blood vessel detection imaging apparatus can be used. The result is more accurate detection of body parts that are difficult to detect.

The image processing unit 30 of the subcutaneous blood vessel detection imaging apparatus of the present invention includes an optical lens 31 for receiving the light reflected from the subject and irradiated from the first and second light source units, and infrared transmission through which the light passing through the optical lens passes. It may include a filter 32, a camera detector 33 for detecting the light transmitted through the infrared transmission filter, and a signal processor 34.

The subcutaneous blood vessel detection imaging apparatus of the present invention can receive light reflected from a subject by being irradiated from the first light source unit and the second light source unit using the optical lens 31. In addition, the optical lens of the present invention may be an optical zoom lens, it is possible to obtain an optically enlarged image through the optical zoom lens. Unlike screen magnification through digital image processing, the original image itself is magnified by using a lens, so that a clear magnified image can be obtained without blurring of the image. Based on this, it is possible to detect the capillaries and the like which are indistinguishable due to their thin thickness. In addition, the shutter may be mounted inside the optical lens to adjust the intensity of the incoming image.

The present invention can obtain an effective noise removing effect by filtering out the light reflected by the infrared transmission filter 32 immediately after the irradiated infrared rays are reflected from the skin and immediately before being detected by the camera detector 33. The infrared transmission filter is not used to selectively filter out the wavelength of the light source, but is used to prevent noise from the external light source from entering the detector. For example, since the infrared LED has a narrow wavelength range of 10 nm, it also has a filter effect necessary to select a specific wavelength when using a broad wavelength light source such as a lamp, and thus has a double filtering effect as a whole. The absorption of blood by a specific wavelength is enhanced by the infrared LED, and noise by an external light source is blocked by the optical filter, thereby clarity of the image may be maximized.

According to the present invention, the image information of blood vessels is obtained in the form of digital data through the camera detector 33, so that the image information can be easily processed and visualized in a desired form. For example, since digitized blood vessel image information can be used to visualize the exact position of blood vessels in a variety of forms, such as expressing a separate line, it can be helpful for accurate position detection of blood vessels. Also, by adding various colors to the image, the color and shape of the actual object to be observed can be realized to obtain the same effect as seeing the blood vessel viewing the blood vessel on the actual skin. In addition, the camera detector may include one or more CCD digital cameras, and may include a black and white blood vessel image and a color skin image through the plurality of CCD digital cameras, and combine the obtained images.

The signal processor 34 in the image processor 30 of the present invention may process and generate image information so that the light obtained from the camera detector may be displayed on the image display unit 40. Also, the signal processor 34 may display a warning or guidance message on the image display unit 40 when the generated image information does not satisfy a predetermined condition. For example, when the noise of the generated image information is included in a predetermined ratio or more, the signal processor 34 displays a warning or guidance message on the image display unit to adjust a distance or angle at which light is emitted from the second light source unit. You can also In this way, the operator may obtain the optimal subcutaneous blood vessel detection image by adjusting the light irradiation angle or distance of the portable second light source unit.

The image display unit 40 of the subcutaneous blood vessel detection imaging apparatus of the present invention displays the subcutaneous blood vessel detection image processed by the image processor 30. In addition, the image display unit 40 may display a guide message indicating that irradiation of the subcutaneous blood vessel detection image and / or light is correctly performed when the image acquired from the camera detector 33 satisfies a predetermined condition. If the image acquired from (33) does not satisfy a predetermined condition, a warning or guide word may be displayed. In addition, the image display unit 40 may display various types of information necessary for using the subcutaneous blood vessel detection imaging apparatus of the present invention.

Next, the operation principle of the subcutaneous blood vessel detection imaging apparatus and the method of detecting the subcutaneous blood vessel will be described.

Only infrared image information including the image of the blood vessel passing through the infrared transmission filter reaches the camera detector 33.

The subcutaneous blood vessel detection method of the present invention includes processing and generating image information that can be displayed on the image display unit 40 using the light detected by the camera detection unit 33. The signal processor 34 converts light obtained by the camera detector into image information, and the converted image information is visualized through the image display unit.

The subcutaneous blood vessel detection method of the present invention includes outputting the processed image information. The outputting of the image information may include processing and outputting the image information such as expressing the position of the vessel by a separate line or applying color so that the vessel information can be visualized in a desired form.

In addition, the outputting of the image information may include displaying a warning or guidance message on the image display unit 40 when the acquired image does not satisfy a predetermined condition. For example, the signal processor 34 may warn or guide a message to adjust the distance or angle at which light is emitted from the second light source unit when the noise of the image acquired from the camera detector 33 is included in a predetermined ratio or more. May be displayed on the image display unit. In this case, the operator may return to irradiating the subject with the infrared light through the second light source, and adjust the distance and / or the angle at which the infrared light from the second light is irradiated to the subject, thereby obtaining an optimal subcutaneous blood vessel detection image. have.
