Description

[규칙 제26조에 의한 보정 19.04.2019]　안구촬영장치[Correction 19.04.2019 according to Rule 26] 　Eye photographing device
본 발명은 안구촬영장치에 관한 것으로서, 더욱 상세하게는 복합적인 생체 정보 데이터를 기반으로 원격 의료 진단 및 관리를 가능하게 하는 안구촬영장치에 관한 것이다.The present invention relates to an ocular imaging apparatus, and more particularly, to an ocular imaging apparatus that enables remote medical diagnosis and management based on complex biometric information data.
최근 안구 검사를 통해 눈과 관련된 다른 신체의 건강상태나 질병을 진단하고자 하는 연구가 많이 진행되고 있다. Recently, a lot of research has been conducted to diagnose other health conditions or diseases related to the eye through eye examination.
안구 검사는 의사가 직접 피검사자의 눈을 육안으로 관찰하는 방법으로 진행될 수 있으나, 안구촬영장치를 사용하여 안구 이미지를 촬영하는 경우, 피검사자의 안구 각막, 수정체, 안구 전방을 포함하는 전 구역 및 안구의 바닥을 포함하는 후 구역 등을 좀 더 정밀하게 진단할 수 있다. 특히, 안구는 신체의 모든 부위들 중 유일하게 혈관을 직접 관찰할 수 있는 부위이며, 안구 이미지를 통해 안구 혈관을 관찰함으로써, 고혈압 환자의 병의 경중을 판단할 수 있고, 당뇨의 눈 합병증 검사를 할 수 있다. 또한, 안구는 녹내장, 뇌압상승, 시신경염, 허혈성신경증 등 다양한 시신경 질환의 진단에 이용되고 다양한 혈관 질환을 진단하는데 이용될 수 있다.Eye examination can be performed by a doctor directly observing the eye of the subject with the naked eye. However, when taking an eye image using an ocular imaging device, the entire area including the eye cornea, the lens, and the anterior eye of the eye It is possible to more accurately diagnose the posterior area including the floor. In particular, the eyeball is the only area in which blood vessels can be directly observed among all parts of the body, and by observing the blood vessels of the eyeball through the eyeball image, the severity of the disease in hypertensive patients can be judged, and eye complications of diabetes can be examined. can do. In addition, the eyeball can be used for diagnosis of various optic nerve diseases such as glaucoma, elevated brain pressure, optic neuritis, ischemic neurosis, and various vascular diseases.
그러나, 종래의 안구촬영장치는 테이블 및 장치 프레임 등에 고정된 상태에서 피검사자의 안구를 검사하기 때문에 일반적으로 피검사자들이 휴대할 수 없으며, 피검사자는 안구 검사를 받기 위해서 안구촬영장치가 구비된 병원과 같은 의료기관에 방문해야만 하는 번거로움이 있다. 특히, 의료기관이 부족한 지역에서는 안구 검사를 받는 것이 어렵다.However, since conventional eye photographing devices inspect the eyes of the test subject while they are fixed on a table and device frame, the test subjects cannot generally carry them, and the test subject is a medical institution such as a hospital equipped with an eye photographing device to receive an eye examination. There is a hassle of having to visit to. In particular, it is difficult to undergo an eye examination in areas where medical institutions are scarce.
또한, 우수한 품질의 안구 이미지를 촬영하기 위해서는 안구를 촬영할 수 있는 숙련된 전문가에 의해 안구촬영장치가 조작되어야 한다. 이처럼 안구촬영장치는 숙련된 전문가가 아니면, 정확한 안구 이미지를 획득하기 어렵고, 안구 질병을 정확하게 진단하기 어려운 단점이 있다. In addition, in order to capture a high-quality eye image, the eye photographing apparatus must be operated by an expert who can photograph the eye. As described above, the eye photographing apparatus has disadvantages in that it is difficult to obtain an accurate eye image, and it is difficult to accurately diagnose eye diseases unless you are an experienced expert.
또한, 종래의 안구촬영장치는 피검사자의 안구만 촬영하기 때문에, 안과 질환 이외에 혈관과 관련된 질병과 시신경과 관련된 질병의 진단이 어렵다는 단점이 있다.In addition, since the conventional ocular imaging apparatus photographs only the eye of the subject, it is difficult to diagnose diseases related to blood vessels and diseases related to the optic nerve in addition to ophthalmic diseases.
따라서, 종래의 안구촬영장치들이 가지고 있는 문제점을 보완하여 피검사자가 안구촬영장치를 휴대할 수 있으며, 비전문가들이 안구를 촬영해도 정확한 안구 이미지를 생성할 수 있고, 안구 이미지를 통해 안구 질병을 진단할 뿐만 아니라 여러가지의 복합적인 생체 정보 데이터를 기반으로 안구 혈관 및 시신경계와 관련된 다양한 질병을 진단할 수 있는 기술이 필요하게 되었다. Therefore, by supplementing the problems of conventional eye photographing devices, the subject can carry the eye photographing device, and even if non-professionals photograph the eye, an accurate eye image can be generated, and eye diseases can be diagnosed through the eye image. In addition, there is a need for a technology capable of diagnosing various diseases related to the blood vessels of the eye and the optic nervous system based on a variety of complex biometric data.

광학부는 안구에서 반사된 광을 수집할 수 있다. 광학부는 하나 이상의 렌즈, 편광 필터 및 광 스플리터 등을 구비할 수 있다. 광학부는 안구에서 반사된 광들의 이동 경로를 제어함으로써, 안구에서 반사된 광들이 이미지 생성부로 수집될 수 있다.The optical unit may collect light reflected from the eyeball. The optical unit may include one or more lenses, polarizing filters, and optical splitters. The optical unit controls the movement path of the light reflected from the eyeball, so that the light reflected from the eyeball may be collected by the image generator.
이미지 생성부는 광학부를 통과한 광을 센싱하여 안구 이미지를 생성할 수 있다. 예를 들어, 이미지 생성부는 광원을 통해 조사되어 안구에서 반사된 광을 센싱함으로써 안구 이미지를 생성할 수 있다. The image generator may generate an eyeball image by sensing light passing through the optical unit. For example, the image generator may generate an eyeball image by sensing light reflected from the eyeball by being irradiated through a light source.
위치 조절부는 이미지 생성부에 의해 선명한 안구 이미지가 생성되도록 광원, 광학부 및 이미지 생성부의 위치를 조절하며, 광학부의 초점을 조절할 수 있다. The position adjusting unit may adjust the positions of the light source, the optical unit, and the image generating unit so that a clear eye image is generated by the image generating unit, and may adjust the focus of the optical unit.
촬영부(120)의 위치 조절부는 피검사자의 좌안 및 우안 중 어느 하나를 촬영한 후, 나머지 하나의 촬영을 위해 촬영부(120)의 위치를 이동시킬 수 있다. The position adjusting unit of the photographing unit 120 may move the position of the photographing unit 120 for the other photographing after photographing any one of the left eye and the right eye of the test subject.
한편, 촬영부(120)의 위치 조절부는 피검사자의 안구와 촬영부(120) 사이의 거리를 자동으로 조절함으로써, 피검사자가 숙련된 전문가의 도움 없이도, 용이하게 본인의 안구를 촬영하도록 할 수 있다. 예를 들어, 위치 조절부는 각막에서 반사된 광의 정보들로부터 각막과 촬영부(120) 사이의 거리를 예측하고, 그 거리가 레퍼런스 거리에 대응되도록 촬영부(120)의 위치를 제어할 수 있다. On the other hand, the position adjusting unit of the photographing unit 120 automatically adjusts the distance between the eyeball of the subject and the photographing unit 120, so that the subject can easily photograph his/her own eyes without the help of an experienced expert. For example, the position controller may predict a distance between the cornea and the photographing unit 120 from information of light reflected from the cornea, and control the position of the photographing unit 120 so that the distance corresponds to the reference distance.

도 2를 참조하면, 신체정보 수집부(130)는 뇌파 측정부(131), 심전도 측정부(132) 및 산소포화도 측정부(133) 중 적어도 하나를 포함할 수 있다. 비록, 도 2에는 신체정보 수집부(130)가 뇌파 측정부(131), 심전도 측정부(132) 및 산소포화도 측정부(133)를 모두 포함하는 것으로 도시되어 있으나, 신체정보 수집부(130)는 뇌파 측정부(131), 심전도 측정부(132) 및 산소포화도 측정부(133) 중 적어도 하나의 측정부만 포함할 수도 있다. Referring to FIG. 2, the body information collection unit 130 may include at least one of an EEG measurement unit 131, an electrocardiogram measurement unit 132, and an oxygen saturation measurement unit 133. Although, in FIG. 2, the body information collection unit 130 is shown to include all of the EEG measurement unit 131, the electrocardiogram measurement unit 132, and the oxygen saturation measurement unit 133, the body information collection unit 130 May include only at least one of the EEG measurement unit 131, the electrocardiogram measurement unit 132, and the oxygen saturation measurement unit 133.
뇌파 측정부(131)는 피검사자의 뇌파를 측정할 수 있다. 여기서, 뇌파(EEG, electro-encephalography)는 뇌의 전기적인 활동을 머리 표면에 접촉된 전극(Electrode)에 의해 비침습적으로 측정한 전기신호이다. 뇌파(EEG, electro-encephalography)는 신경계와 뇌신경 사이에 신호가 발생할 때 생기는 미세한 생체 전기로써, 뇌 표면에서 발생하는 전기 포텐셜 차이를 전극을 사용하여 측정한다. 뇌파 신호는 델타(δ)파, 쎄타(θ)파, 알파(α)파, 베타(β)파 및 감마(γ)파로 분류된 주파수 분석을 통해 스펙트럼으로 볼 수 있다. 뇌파에 반영되는 뇌의 전기적 활동은 신경세포(neurons), 교세포(glia cells), 혈뇌장벽(blood-brain barrier)에 의해 결정되는데 주로 신경세포에 의해 발생된다.The EEG measurement unit 131 may measure EEG of a subject. Here, electro-encephalography (EEG) is an electrical signal obtained by non-invasively measuring the electrical activity of the brain by an electrode in contact with the head surface. EEG (electro-encephalography) is a microscopic bioelectricity generated when a signal is generated between the nervous system and the cranial nerve, and the electric potential difference generated on the brain surface is measured using an electrode. The EEG signal can be viewed as a spectrum through frequency analysis classified into delta (δ) waves, theta (θ) waves, alpha (α) waves, beta (β) waves, and gamma (γ) waves. The electrical activity of the brain reflected in EEG is determined by neurons, glia cells, and blood-brain barriers, and is mainly generated by neurons.
뇌파 측정부(131)는 좌뇌 및 우뇌에서 발생된 뇌파 전위를 전극을 이용하여 머리 표면의 전위차를 측정한다. 이때, 전극을 통해 수신된 뇌파 신호는 준위가 낮기 때문에 직접적인 이용이 용이하지 않다. 이에 따라, 뇌파 측정부(131)는 전극에서 출력되는 신호를 증폭시키고 증폭된 신호를 디지털 신호로 변환함으로써, 뇌의 상태를 측정할 수 있다. The EEG measurement unit 131 measures the electric potential difference on the surface of the head by using the EEG electric potential generated in the left and right brains. In this case, since the EEG signal received through the electrode has a low level, it is not easy to use it directly. Accordingly, the brain wave measurement unit 131 may amplify the signal output from the electrode and convert the amplified signal into a digital signal, thereby measuring the state of the brain.
본 발명에 사용되는 뇌파 측정은 비침습적인 전기신호를 이용할 수 있다. 그러나, 이에 한정되는 것은 아니다. 일반적으로 비침습적인 방법을 이용하여 뇌파를 측정하는 경우, 헬멧 또는 헤드셋 형태의 장비로 뇌파를 측정할 수 있으며, 통상 머리 표면에 해당되는 부위에 전극을 장착한다. EEG measurement used in the present invention may use a non-invasive electrical signal. However, it is not limited thereto. In general, when measuring EEG using a non-invasive method, EEG can be measured with a helmet or headset-type device, and electrodes are usually mounted on a portion corresponding to the head surface.
본 발명에 따른 뇌파 측정부(131)는 피검사자의 눈썹 위의 피부에 접촉되도록 구성되어 피검사자가 안구를 촬영하는 동안 자연스럽게 뇌파를 측정할 수 있도록 구성된다. The EEG measurement unit 131 according to the present invention is configured to be in contact with the skin above the eyebrow of the test subject so that the test subject can naturally measure the EEG while photographing the eyeball.
예를 들어, 본 발명에 따른 뇌파 측정부(131)는 안구촬영장치(10)의 접촉부(140)에 배치된다. 구체적으로, 머리의 두피에 뇌파 전극을 접촉시켜 뇌파를 측정하는 것은 숙련자가 전극과 두피를 전기적으로 연결해주어야 가능하기 때문에 피검사자가 혼자 측정하기 어렵고 준비 시간이 오래 소요될 수 있다. 본 발명에 따른 뇌파 측정부(131)는 접촉부(140)의 수납홈(141)을 통해 뇌파 전극을 삽입하여 피검사자의 눈썹 위의 피부에 뇌파 전극을 접촉시킴으로써, 피검사자의 고통없이 간편하게 뇌파를 직접 측정할 수 있다.For example, the EEG measurement unit 131 according to the present invention is disposed on the contact portion 140 of the eye photographing apparatus 10. Specifically, measuring the EEG by contacting the EEG electrode to the scalp of the head can be difficult for the test subject to measure alone and a long preparation time, since it is possible for a skilled person to electrically connect the electrode and the scalp. The EEG measurement unit 131 according to the present invention inserts the EEG electrode through the receiving groove 141 of the contact unit 140 to contact the EEG electrode on the skin above the eyebrow of the test subject, thereby directly measuring EEG without pain of the subject. can do.
접촉부(140)는 피검사자가 안구촬영장치(10)를 착용하는 경우, 피검사자의 안면에 접촉되는 부분일 수 있다. 접촉부(140)는 피검사자의 안면의 굴곡에 대응하는 구조를 가질 수 있다. 또한, 접촉부(140)는 피검사자의 안면과 안정적으로 밀착되며, 피검사자의 양안에 외부광을 효과적으로 차광하기 위하여 검은색 계열의 탄성 재질(고무, 실리콘 등)로 형성될 수 있다. 접촉부(140)에는 일부 영역에 피검사자의 코가 삽입될 수 있는 형상을 갖는 홈이 형성될 수 있다. 접촉부(140)는 안구 촬영 중에 피검사자의 양안에 암실을 제공할 수 있어 동공 반사를 최소화할 수 있다. 이를 통해, 본 발명에 따른 안구촬영장치(10)는 피검사자의 안구 이미지를 정확히 촬영할 수 있다.The contact part 140 may be a part that contacts the face of the test subject when the test subject wears the eye photographing apparatus 10. The contact part 140 may have a structure corresponding to the curvature of the face of the test subject. In addition, the contact part 140 may be formed of an elastic material (rubber, silicone, etc.) of a black color in order to stably contact the face of the test subject and effectively shield external light from both eyes of the test subject. A groove having a shape into which the nose of the test subject can be inserted may be formed in the contact part 140. The contact unit 140 may provide dark rooms to both eyes of the subject during eye photographing, thereby minimizing pupil reflection. Through this, the eye photographing apparatus 10 according to the present invention can accurately capture an eye image of a subject.
뇌파 측정부(131)는 피검사자의 눈 주변의 안면에 접촉되는 접촉부(140)에 위치되고, 피검사자가 안구촬영장치(10)를 통해 안구를 촬영하는 동안 자연스럽게 눈썹 위의 피부가 뇌파 측정부(131)에 접촉되도록 구성될 수 있다. The EEG measurement unit 131 is located at the contact unit 140 that contacts the face around the eyes of the test subject, and while the test subject photographs the eye through the eye photographing apparatus 10, the skin above the eyebrows is naturally applied to the EEG measurement unit 131 ) Can be configured to contact.
뇌파 측정부(131)는 본체(110)의 내부에 배치되는 뇌파 측정 모듈(131a) 및 피검사자의 눈썹 위의 피부에 접촉하는 적어도 하나의 뇌파 측정 전극(131b)을 포함할 수 있다. 여기서, 피검사자의 눈썹 위의 피부에 접촉하는 뇌파 측정 전극(131b)은 피검사자의 피부에 흐르는 전기신호를 감지할 수 있다. 이후, 뇌파 측정 모듈(131a)은 뇌파 측정 전극(131b)에서 감지된 전기신호를 증폭 및 처리하여 뇌파 신호를 생성하고 생성된 뇌파 신호를 수집할 수 있다. The EEG measurement unit 131 may include an EEG measurement module 131a disposed inside the main body 110 and at least one EEG measurement electrode 131b contacting the skin above the eyebrow of the test subject. Here, the electroencephalogram measuring electrode 131b in contact with the skin above the eyebrow of the test subject may detect an electric signal flowing through the skin of the test subject. Thereafter, the EEG measurement module 131a may amplify and process the electrical signal detected by the EEG measurement electrode 131b to generate an EEG signal and collect the generated EEG signal.
접촉부(140)는 뇌파 측정부(131)의 뇌파 측정 전극(131b)이 삽입되는 수납홈(141)을 포함할 수 있다. 뇌파 측정부(131)의 일면은 접촉부(140)의 일면보다 본체(110)의 내부 방향으로 함몰되어 배치되며, 피검사자의 안면에 의해 접촉부(140)의 일면이 압축되는 경우, 뇌파 측정부(131)의 일면은 접촉부(140)의 일면 상으로 노출될 수 있다.The contact unit 140 may include a receiving groove 141 into which the EEG measurement electrode 131b of the EEG measurement unit 131 is inserted. One surface of the EEG measurement unit 131 is disposed to be recessed in the inner direction of the body 110 than the one surface of the contact unit 140, and when one surface of the contact unit 140 is compressed by the face of the test subject, the EEG measurement unit 131 One surface of) may be exposed on one surface of the contact part 140.
수납홈(141)은 접촉부(140)의 내측면 둘레에 형성되어 뇌파 측정부(131)의 뇌파 측정 전극(131b)이 삽입되는 입구로 기능할 수 있다. 예를 들어, 수납홈(141)은 뇌파 측정 전극(131b)의 밑면 형상에 대응되도록 원 형상으로 형성될 수 있으나 이에 제한되지 않는다. The receiving groove 141 may be formed around the inner surface of the contact part 140 to function as an entrance into which the EEG measurement electrode 131b of the EEG measurement unit 131 is inserted. For example, the receiving groove 141 may be formed in a circular shape to correspond to the shape of the bottom surface of the EEG measurement electrode 131b, but is not limited thereto.
수납홈(141)은 뇌파 측정 전극(131b)의 일단부 측이 삽입되어 걸리도록 형성될 수 있다. 이때, 수납홈(141)에 삽입된 뇌파 측정 전극(131b)은 피검사자의 안면과 대향되는 방향으로 수납홈(141) 입구에 돌출되지 않도록 할 수 있다. 이 경우, 뇌파 측정 전극(131b)은 뇌파 측정 전극(131b)의 일면에 이물질 등이 묻어 뇌파 측정부(131)가 오작동 되는 것을 억제시킬 수 있다. 피검사자가 안구를 촬영하는 동안은 피검사자의 안면에 의해 접촉부(140)가 압축되어 피검사자의 안면과 접촉부(140)의 뇌파 측정 전극(131b)의 일면이 서로 가까워진다. 접촉부(140) 가 충분히 압축되는 경우, 수납홈(141) 입구로 뇌파 측정 전극(131b)이 자연스럽게 노출되어 피검사자의 눈썹 위 피부에 접촉된다. 이 경우, 뇌파 측정 전극(131b)은 뇌파 측정 전극(131b) 외에 다른 물체가 접촉되는 것을 방지할 수 있고, 피검사자의 뇌파를 정확하게 측정할 수 있다. The receiving groove 141 may be formed such that one end side of the EEG measurement electrode 131b is inserted and caught. In this case, the EEG measurement electrode 131b inserted into the receiving groove 141 may not protrude from the entrance of the receiving groove 141 in a direction facing the face of the test subject. In this case, the EEG measurement electrode 131b may suppress a malfunction of the EEG measurement unit 131 due to foreign substances or the like on one surface of the EEG measurement electrode 131b. While the test subject photographs the eyeball, the contact part 140 is compressed by the test subject's face, so that the test subject's face and one surface of the EEG measuring electrode 131b of the contact part 140 become close to each other. When the contact portion 140 is sufficiently compressed, the EEG measurement electrode 131b is naturally exposed through the entrance of the receiving groove 141 to contact the skin above the eyebrow of the test subject. In this case, the EEG measurement electrode 131b may prevent an object other than the EEG measurement electrode 131b from contacting, and accurately measure the EEG of the subject.
또한, 뇌파 측정 전극(131b)은 고무 재질의 접촉부(140)에 비해 단단한 금속 재질로 구성되므로, 피검사자가 안구를 촬영하는 동안 피검사자의 피부에 접촉되어 마찰력을 증대시킨다. 이에, 연질의 접촉부(140)가 슬립(slip)되는 것이 최소화될 수 있으며, 이를 통해 안구촬영장치(10)의 위치가 안정적으로 고정될 수 있다. In addition, since the electroencephalogram measurement electrode 131b is made of a harder metal material than the contact part 140 made of rubber, it is in contact with the skin of the test subject while photographing the eyeball to increase friction. Accordingly, slipping of the soft contact part 140 may be minimized, and through this, the position of the eye photographing apparatus 10 may be stably fixed.
한편, 신체정보 수집부(130)는 피검사자의 엄지에 접촉되어 피검사자의 심전도를 측정하도록 구성된 심전도 측정부(132)를 더 포함할 수 있다. Meanwhile, the body information collection unit 130 may further include an electrocardiogram measuring unit 132 configured to measure an electrocardiogram of the subject by contacting the thumb of the subject.
심전도 측정부(132)는 피검사자의 심전도를 측정할 수 있다. 여기서, 심전도(ECG, electrodardiogram)는 심장근육의 수축 확장에 따른 활동 전류를 외부에서 전극을 부착하여 측정 및 기록한 것이다. 심장근육이 수축 이완할 때 발생되는 활동전위는 심장으로부터 온 몸으로 퍼지는 전류를 일으키고 이 전류는 몸의 위치에 따라 전위차를 발생시키는데, 이 전위차는 인체의 피부에 부착된 표면전극(surface electrode)을 통해 검출하여 기록할 수 있다. 이와 같은 심전도는 심장의 이상유무 확인에 이용되며, 협심증, 심근경색, 부정맥 등 심장질환계의 질환을 측정하는 데에는 기본적인 방법으로 이용된다. 심전도 측정에는 수직모드(vertical mode)와 수평 모드(horizontal mode)가 있다. The electrocardiogram measuring unit 132 may measure an electrocardiogram of a test subject. Here, the ECG (electrodardiogram) is a measurement and recording of an active current according to contraction and expansion of the heart muscle by attaching an electrode from the outside. The action potential generated when the heart muscle contracts and relaxes causes a current that spreads from the heart to the whole body, and this current generates a potential difference depending on the position of the body. This potential difference causes the surface electrode attached to the skin of the human body. It can be detected and recorded through. Such an electrocardiogram is used to check the presence of abnormalities in the heart, and is used as a basic method to measure diseases of the heart disease system, such as angina, myocardial infarction, and arrhythmia. There are two types of ECG measurement: a vertical mode and a horizontal mode.
본 발명에 사용되는 심전도 측정은 수직모드(vertical mode)일 수 있다. 그러나, 이에 한정되는 것은 아니다. 일반적으로 수직 모드의 측정인 경우, 어느 신체에 전극을 부착하여도 상관없으며, 통상 양쪽 손목과 왼쪽 발목에 전극을 장착할 수 있고, 손목 또는 발목이 아니라 몸체 가까이에 전극을 둘 수도 있고, 좀 더 심장으로부터 먼 쪽, 예를 들면 손가락이나 발가락 끝 등에 전극을 두더라도 동일한 결과를 얻을 수 있다. 본 발명에 따른 심전도 측정부(132)는 피검사자의 손가락 중 엄지를 사용하여 심전도를 측정할 수 있다. The electrocardiogram measurement used in the present invention may be in a vertical mode. However, it is not limited thereto. In general, in the case of measurement in the vertical mode, it does not matter which body the electrode is attached to. Usually, electrodes can be attached to both wrists and left ankles, and electrodes can be placed close to the body rather than wrists or ankles, and more The same results can be obtained by placing electrodes away from the heart, such as the tip of a finger or toe. The electrocardiogram measuring unit 132 according to the present invention may measure an electrocardiogram using a thumb among fingers of a test subject.
본 발명에 따른 심전도 측정부(132)는 본체(110) 중 피검사자의 안면에 대향되는 일면의 양측에 위치될 수 있다. 예를 들어, 심전도 측정부(132)는 피검사자가 안구를 촬영하기 위해 안구촬영장치(10)를 양손으로 들 때 양손의 엄지가 접촉되는 부분에 위치될 수 있다. 심전도 측정부(132)는 피검사자의 오른쪽 엄지와 접촉하는 부분과 피검사자의 왼쪽 엄지와 접촉하는 부분에 각각 이격되어 위치될 수 있다. The electrocardiogram measuring unit 132 according to the present invention may be located on both sides of one side of the body 110 that faces the face of the test subject. For example, the electrocardiogram measuring unit 132 may be positioned at a portion where the thumb of both hands comes into contact when the test subject holds the eye photographing apparatus 10 with both hands in order to photograph the eyeball. The electrocardiogram measuring unit 132 may be positioned to be spaced apart from a portion in contact with the right thumb of the test subject and a portion in contact with the left thumb of the test subject.
심전도 측정부(132)는 전극을 구비할 수 있다. 심전도 측정부(132)에 구비된 전극은 피검사자의 엄지에 접촉된다. 이 상태에서, 피검사자가 안구촬영장치(10)를 작동시키면, 심전도 측정부(132)도 함께 작동될 수 있다. 이때, 심전도 측정부(132)에 구비된 측정센서가 피검사자의 엄지를 통해 전달되는 전류를 전극을 통해 감지함으로써, 피검사자의 심전도를 측정하고 정보를 수집할 수 있다. The electrocardiogram measurement unit 132 may include an electrode. The electrodes provided in the electrocardiogram measuring unit 132 are in contact with the thumb of the test subject. In this state, when the subject operates the eye photographing apparatus 10, the electrocardiogram measurement unit 132 may also be operated. In this case, the measurement sensor provided in the electrocardiogram measuring unit 132 senses the current transmitted through the thumb of the test subject through the electrode, so that the electrocardiogram of the test subject may be measured and information may be collected.
또한, 피검사자의 엄지와 접촉되는 심전도 측정부(132) 접촉 부분은 단단한 금속 재질로 구성되므로, 피검사자가 심전도를 측정하는 동안 피검사자의 엄지에 접촉되어 마찰력을 증대시킨다.In addition, since the contact portion of the electrocardiogram measuring unit 132 in contact with the subject's thumb is made of a hard metal material, the subject's thumb is in contact with the subject's thumb while measuring the electrocardiogram to increase friction.
상술한 바와 같이, 심전도 측정부(132)는 피검사자가 안구촬영장치(10)를 잡을 때 피검사자의 엄지가 위치하는 부분에 위치된다. 이 경우, 피검사자는 특별한 노력없이 안구 이미지를 촬영하는 동안 자연스럽게 심전도를 측정할 수 있다. 특히, 피검사자는 안구 촬영동안 안구촬영장치(10)를 안정적으로 지지하기 위해 손가락을 안구촬영장치(10)에 밀착시킬 것이므로, 심전도 측정부(132)의 전극과 피검사자의 엄지는 안정적으로 접촉될 수 있다. 이에, 피검사자의 심전도는 더욱 안정적으로 측정될 수 있다. As described above, the electrocardiogram measuring unit 132 is located at a portion where the thumb of the test subject is located when the test subject holds the eye photographing apparatus 10. In this case, the test subject can naturally measure the electrocardiogram while taking the eyeball image without any special effort. In particular, since the test subject will put a finger in close contact with the eye photographing device 10 to stably support the eye photographing device 10 during eye photographing, the electrode of the electrocardiogram measuring unit 132 and the thumb of the test subject can stably contact. have. Accordingly, the ECG of the test subject can be measured more stably.
한편, 신체정보 수집부(130)는 피검사자의 손가락에 접촉되어 피검사자의 산소포화도를 측정하도록 구성된 산소포화도 측정부(133)를 더 포함할 수 있다. Meanwhile, the body information collection unit 130 may further include an oxygen saturation measurement unit 133 configured to measure the oxygen saturation level of the subject by contacting the finger of the test subject.
산소포화도 측정부(133)는 피검사자의 산소포화도를 측정할 수 있다. 여기서, 산소포화도는 혈액내 산소와 결합한 헤모글로빈의 양이 전체 헤모글로빈의 양에서 차지하는 비율을 백분율로 수치화한 지표이다. 즉, 산소포화도를 측정함으로써, 적혈구에 의해 운반되는 산소의 양으로 얼마나 효과적으로 호흡하고 있는지, 산소가 전신에 잘 전달되고 있는지 등을 알아볼 수 있다. The oxygen saturation measurement unit 133 may measure the oxygen saturation of the test subject. Here, the degree of oxygen saturation is a numerical index of the ratio of the amount of hemoglobin bound to oxygen in the blood to the total amount of hemoglobin as a percentage. That is, by measuring the oxygen saturation, it is possible to find out how effectively you are breathing with the amount of oxygen carried by red blood cells, whether oxygen is well delivered to the body, and the like.
본 발명에 사용되는 산소포화도 측정은 혈중산소포화도(SPO2, saturation of partial pressure oxygen)를 측정하는 센서를 이용하여 피검사자의 산소포화도를 측정할 수 있다. 혈중 산소포화도 센서를 이용한 산소포화도 측정은 심장의 수축과 이완으로 변화하는 혈액 용적과 혈액 내의 헤모글로빈에 흡수되는 빛의 양의 선형적 관계를 이용하여 신호를 획득하는 방법이다. 예를 들어, 생체에 투과성 빔을 사용하여 적외선 광도변화를 측정하는 방법으로 측정될 수 있다. 일반적으로 산소포화도 측정은 손목, 손가락, 발가락, 귓볼 등에서 측정할 수 있다. 그러나, 이에 한정되는 것은 아니다.The oxygen saturation measurement used in the present invention can measure the oxygen saturation of the test subject using a sensor that measures the saturation of partial pressure oxygen (SPO2). Oxygen saturation measurement using a blood oxygen saturation sensor is a method of obtaining a signal using a linear relationship between the volume of blood that changes due to contraction and relaxation of the heart and the amount of light absorbed by hemoglobin in the blood. For example, it may be measured by a method of measuring a change in infrared light intensity using a transmissive beam on a living body. In general, oxygen saturation can be measured on the wrist, fingers, toes, and earlobe. However, it is not limited thereto.
본 발명에 따른 산소포화도 측정부(133)는 피검사자의 손가락으로부터 산소포화도를 측정할 수 있다. 예를 들어, 산소포화도 측정부(133)는 피검사자가 안구를 촬영하기 위해 안구촬영장치(10)를 양손으로 들 때, 양손의 손가락 중 하나의 손가락이 접촉되는 부분에 배치될 수 있다. 산소포화도 측정부(133)는 피검사자의 오른쪽 손가락 중 하나의 손가락과 접촉하는 부분과 피검사자의 왼쪽 손가락 중 하나의 손가락과 접촉하는 부분에 각각 이격되어 배치될 수 있다. The oxygen saturation level measuring unit 133 according to the present invention may measure the oxygen saturation level from a finger of the test subject. For example, the oxygen saturation measurement unit 133 may be disposed at a portion where one of the fingers of both hands comes into contact when the test subject lifts the eye photographing apparatus 10 with both hands to photograph the eyeball. The oxygen saturation measurement unit 133 may be disposed to be spaced apart from a portion in contact with one finger of the subject's right finger and a portion in contact with one finger of the subject's left finger.

도 3 및 도 4를 참조하여, 본 발명의 일 실시예에 따른 안구촬영장치(10)를 이용하여 신제정보를 수집하는 방법을 구체적으로 설명한다.3 and 4, a method of collecting new drug information using the eye photographing apparatus 10 according to an embodiment of the present invention will be described in detail.
도 3은 도 1의 안구촬영장치(10)를 이용하여 뇌파를 측정하는 방법을 나타낸 도면이고, 도 4는 도 1의 안구촬영장치(10)를 이용하여 심전도 및 산소포화도를 측정하는 방법을 나타낸 도면이다.3 is a view showing a method of measuring an EEG using the eye photographing device 10 of FIG. 1, and FIG. 4 is a diagram showing a method of measuring an electrocardiogram and oxygen saturation using the eye photographing device 10 of FIG. 1 It is a drawing.
도 3 및 도 4를 참조하면, 피검사자는 두손으로 안구촬영장치(10)를 잡고 안구를 촬영할 수 있도록 피검사자의 눈 주변의 안면을 안구촬영장치(10)의 접촉부(140)에 접촉시킨다. 피검사자가 안구촬영장치(10)의 접촉부(140)에 피검사자의 눈 주변의 안면을 접촉시키면, 안구촬영장치(10)는 피검사자의 안구 촬영을 시작한다. 동시에, 안구촬영장치(10)는 접촉부(140)의 수납홈(141)에 삽입되어 있는 뇌파 측정부(131)를 통해 피검사자의 뇌파를 측정할 수 있다.Referring to FIGS. 3 and 4, the examinee holds the eye photographing apparatus 10 with both hands and makes the face around the eyes of the examinee in contact with the contact part 140 of the eye photographing apparatus 10 so that the eye can be photographed. When the test subject contacts the face of the subject's eyes with the contact portion 140 of the eye photographing apparatus 10, the eye photographing apparatus 10 starts photographing the eyes of the subject.
