Description

[0002] Hypodermic vein detection imaging apparatus combined with specialized supplement light [0003]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a subcutaneous blood vessel detection system capable of visualizing a blood vessel located under the skin using an infrared light source, and more particularly to a subcutaneous blood vessel detection system capable of obtaining a high quality image through a combination of a main light source and a special auxiliary light source Gt; a < / RTI > subcutaneous vein detection system.

Recently, the demand for cosmetic treatment is increasing day by day, and the problems caused by the side effects of the treatment are increasing. Especially, in case of cosmetic treatment for facial face, the risk of side effects due to erroneous procedures is very high, and it is very important to detect the position of an accurate blood vessel in order to prevent erroneous operation.

There is known a method in which a light source corresponding to infrared rays in ultraviolet rays is used to illuminate the skin, a reflected or transmitted light is filtered using a filter having a narrow transmission area, and images are imaged using a goggle or a projector using various detectors. In addition, light in the near infrared region, which transmits the skin most and has the highest absorption of blood, is known as the most efficient light source, and intensifier tubes, CCD, and CMOS are used as detectors.

However, this is not only complicated and cumbersome to manufacture, but also constitutes a structural obstacle to product manufacturing due to its structure. In addition, since the apparatus according to the related art as described above only displays a real-size image, it is difficult to grasp a minute capillary blood vessel and has a disadvantage of providing only a monochromatic image.

On the other hand, in Patent Document 1, an infrared light source 111 is fixed to the inner surface of a dome-shaped support base 112, and an optical zoom lens 115, an infrared ray transmission filter 116, and a camera 117 are disposed on the dome- A subcutaneous vein detection imaging device 110 is described.

However, since the subcutaneous blood vessel detection imaging apparatus uses only the infrared light source fixed in the dome-type support, it is difficult to irradiate the skin with strong light at close range, and light is difficult to penetrate deeply into the skin. In addition, since the infrared ray light source is fixed in the dome-type support, it is difficult to adjust the angle of light irradiation, so that it is difficult to suppress irregular reflection occurring on the surface of the skin. Thus, .

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

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 processing unit 30, and an image display unit 40.

The first light source part (10) of the subcutaneous blood vessel detection imaging device 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 dome-shaped support having a shape of a cut-out portion as shown in Fig. 1, and an infrared light source such as an infrared LED arranged in the circumferential direction on the inner surface of the dome-shaped support may be arranged. However, the shape of the support may be any shape as long as it can arrange an infrared light source on the inner surface so that infrared rays can be irradiated to the skin.

The second light source part 20 of the subcutaneous blood vessel detection imaging device of the present invention includes a portable second light source part body 21 and a second infrared light source 22 arranged on an inner surface of the second light source part 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 practitioner can carry the second light source body and irradiate the infrared light to a desired position at a desired position . That is, the subcutaneous blood vessel detection imaging apparatus of the present invention can more precisely set the position and distance where the light is irradiated, as compared with the conventional subcutaneous vein detection imaging apparatus in which the infrared light is fixed to the support, Vessel detection images can be obtained.

Fig. 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 opened. For example, the second light source body 21 includes a first body 23, a second body 24, and a third body 25, and the first body 23 includes the third body 25 And the second body 24 may be disposed at the other end of the third body 25. The shape of the first body to the third body may be a 'U' shape as shown in FIG. 3, a 'U' shape having a third body formed of a curved surface, a length of a third body A short 'V' shape, a third body having a short length, and a first body and a second body having an angle of about 90 degrees. The shape in which the first body to the third body are connected is not limited to the above-described shape, and at least one surface may have various shapes that are open.

In the subcutaneous vein detection imaging apparatus of the present invention, at least one surface of the second light source body section is formed to have an open shape, so that a surgeon can more easily irradiate light to the skin and perform a desired procedure. For example, when a practitioner conveys light to the skin by carrying the second light source part body in one hand and performs the procedure using the treatment tool with the other hand, it is possible to form a face open to the second light source body It is possible to freely move the treatment tool through the open face while irradiating the light at a closer distance.

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 body and is not limited to the positions of the arranged surfaces and the number of arranged surfaces. For example, the infrared light source may be arranged on one side of the first body and the second body, on one side of the third body, or on one side 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, and the rod shape may be a shape of a cylinder, a square pillar, a triangular pillar, or the like. The second infrared light source included in the second light source unit may be disposed on at least one side of the second light source body (22). 4A shows an embodiment in which the second light source unit is formed on the entire surface of the second light source body, and arrows indicate the light irradiation direction. 4B shows an embodiment in which the second light source part is formed on one side of the second light source part body, and arrows indicate the direction of light irradiation. The rod-shaped second light source body can be inserted into the hole of the object. The study of a subject (hole) refers to a part made of a hole in the body, such as a nostril or an ear hole. The second light source part body having a rod shape preferably has a diameter of 5 mm or less, more preferably 3 mm or less. For example, the subcutaneous blood vessel detection imaging apparatus of the present embodiment is capable of irradiating infrared rays from the inside of a nose or an ear of a subject to be examined, Can provide more accurate detection results for parts of the body that are difficult to detect.

An image processing unit (30) of a subcutaneous vein detection imaging apparatus of the present invention includes an optical lens (31) irradiated from a first light source unit and a second light source unit and receiving light reflected from an object, an infrared transmission A filter 32, a camera detection unit 33 for detecting light transmitted through the infrared transmission filter, and a signal processing unit 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. [ Further, the optical lens of the present invention may be an optical zoom lens, and an optically magnified image can be obtained through the optical zoom lens. Unlike the screen enlargement through the digital image processing, the original image itself is enlarged by using the lens, so that there is no blur of the image and a clear enlarged image can be obtained. Based on this, it is possible to clearly detect capillaries that are thin and can not be identified. It is also possible to include a function of adjusting the intensity of the incoming image by attaching a shutter to the inside of the optical lens.

The present invention can obtain an effective noise removing effect by filtering the light reflected by the infrared ray transmitting filter 32 immediately before being detected by the camera detecting unit 33 after the irradiated infrared ray is reflected from the skin. The infrared transmission filter is used not to selectively filter the wavelength of the light source but 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 has a filter effect that is necessary for selecting a specific wavelength when a light source of a broadband wavelength such as a lamp is used. The absorption of blood by a specific wavelength is enhanced by the infrared LED, and the noise due to the external light source is blocked by the optical filter, so that the sharpness of the image can be maximized.

The present invention can easily visualize the image information in a desired form by easily obtaining the image information of the blood vessel through the camera detector 33 in the form of digital data. For example, since the digitized blood vessel image information is used, the accurate position of the blood vessel can be visualized in various forms, for example, by displaying it in a separate line. In addition, the color and shape of the actual observation object can be realized so as to obtain the same effect as viewing blood vessels in blood vessels in real skin by adding various colors to the images. Also, the camera detection unit may include one or more CCD digital cameras, and may acquire a blood vessel image of black and white and a skin image of a natural color through a plurality of CCD digital cameras, and may combine the acquired images.

The signal processing unit 34 in the image processing unit 30 of the present invention can process and generate image information so that the light obtained from the camera detection unit can be displayed on the image display unit 40. [ In addition, the signal processing unit 34 may cause the image display unit 40 to display a warning or guidance message 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 processing unit 34 displays a warning or guidance message for adjusting the distance or angle for irradiating the light from the second light source unit to the image display unit . Through this, the operator can adjust the light irradiation angle or distance of the portable second light source unit, thereby obtaining an optimal subcutaneous blood vessel detection image.

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 in the image processing unit (30). The image display unit 40 can display a guidance message indicating that the subcutaneous vein detection image and / or light irradiation is correctly performed when the image obtained from the camera detection unit 33 satisfies a predetermined condition, A warning or a guidance message may be displayed when the image obtained from the image sensor 33 does not satisfy a predetermined condition. In addition, the image display unit 40 may display various 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 subcutaneous blood vessel detection method of the present invention will be described.

The subcutaneous blood vessel detection method of the present invention includes a step of irradiating infrared rays to a subject through a first light source part (10) including an infrared light source and a second light source part (20). Irradiation of infrared light through the first light source unit and the second light source unit may occur at the same time or sequentially, and the order of the infrared light irradiation may not be limited.

The first light source unit 10 is irradiated with infrared rays from an infrared light source arranged on the inner surface of the support, and the infrared rays irradiated by the infrared light source are reflected from the object and directed to the optical lens 31 of the image processing unit 30. The second light source unit 20 is provided to be portable, and the practitioner can carry the second light source unit and irradiate the subject with infrared light at a desired angle at a desired position. The infrared rays irradiated from the second light source part are reflected from the subject and are directed to the optical lens 31 of the image processing part 30. [

The subcutaneous blood vessel detection method of the present invention includes a step of passing light reflected from a subject to an infrared ray transmission filter 32 included in the image processing unit 30. [ Since the light passing through the optical lens 31 passes through the infrared ray transmission filter 32 but other lights can not pass through it, only the infrared ray image information including the image of the blood vessel reaches the camera detection unit 33, An effective noise removing effect can be obtained.

The subcutaneous blood vessel detection method of the present invention includes the step of acquiring light passed through the infrared ray transmission filter (32) by a camera detection unit (33) included in an image processing unit. Only the infrared image information including the image of the blood vessel that has passed through the infrared transmission filter reaches the camera detection unit 33. [

The subcutaneous blood vessel detection method of the present invention includes a step of 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 processing unit 34 converts the light obtained by the camera detecting unit 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 processed image information. The step of outputting the image information may include a step of processing the image information such as the position of the blood vessel by a separate line or coloring the blood vessel so that the blood vessel information can be visualized by the practitioner.

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

In the case of using the subcutaneous blood vessel detection imaging apparatus of one embodiment of the present invention, compared with the case of using the conventional subcutaneous blood vessel detection apparatus using only one light source, the place where the subcutaneous blood vessel is located and the place where the blood vessel is not located are clearly An image to be identified can be obtained. For example, FIG. 5B shows that the subcutaneous blood vessels appearing in the form of black stripes appear more clearly than in FIG. 5A. This means that the noise of the image obtained through the use of the auxiliary light source is reduced.
