Description

[규칙 제26조에 의한 보정 19.11.2014]　동맥 채혈 지원 장치[Correction 19.11.2014 by rule 26] arterial blood collection support device
본 발명은 환자의 동맥혈을 채취하고자 하는 경우, 환자 신체에 착용되는 동맥 채혈 지원 장치를 통해 환자 신체에 대응되는 초음파 영상을 통해 동맥 위치를 보다 용이하게 파악할 수 있도록 하는 동맥 채혈 지원 장치에 관한 것이다. When the arterial blood of the patient is to be collected, the arterial blood collection support device can be more easily identified through the ultrasound image corresponding to the patient's body through the arterial blood collection device worn on the patient's body.
동맥혈 가스분석검사는 호흡기나 순환기의 질환, 인공호흡기 장착 중인 환자 또한 중증환자의 혈중산소, 이산화탄소의 운반상황 등을 파악하기 위해 동맥혈 내의 가스인 혈액 가스를 분석하는 검사이다. Arterial blood gas analysis is a test to analyze blood gas, which is a gas in arterial blood, in order to determine the respiratory or circulatory disease, a patient with a ventilator, and the blood oxygen and carbon dioxide of a serious patient.
동맥혈 가스 분석 검사는, 손목에 존재하는 동맥혈이 폐포에서의 가스 교환 상태를 나타냄을 고려하여 주로 환자의 손목에 존재하는 동맥혈을 채취하여 수행된다. The arterial blood gas analysis test is performed by collecting arterial blood present mainly in the wrist of a patient in consideration of the arterial blood present in the wrist indicating the state of gas exchange in the alveoli.
이에 의료진은 손목에 존재하는 동맥혈을 채취하도록 하는 데, 동맥혈 채혈에 앞서 의료진은 요골동맥의 박동을 손가락 감각으로만 느끼고 위치를 찾아 요골 동맥과 척골 동맥의 소통을 확인하는 알렌 검사(Allen's test)를 수행한 후 동맥혈 채혈 가능유무를 판단한다. 그후 의료진의 손가락 감각으로 요동맥이라 유추한 위치에 채혈용 바늘을 넣어 채혈을 시도한다.The medical staff to collect arterial blood on the wrist, and prior to the arterial blood collection, the medical team feels the pulse of the radial artery only with a finger sensation and locates the Allen test (Allen's test), which confirms the communication between the radial artery and the ulnar artery. After performing it, it is determined whether arterial blood collection is possible. After that, the medical staff's fingers sense the lumbar artery and infer the position of blood collection needle to try to collect blood.
그러나 이와 같은 채혈 방법은 의료진의 손가락 감각에 의지하여 수행되는 지극히 주관적인 검사 방법으로, 의료진의 숙련도에 따라 그 정확도가 달라지는 특징을 가진다. 즉, 의료진의 숙련도가 낮을수록 요동맥의 정확한 위치를 찾아내기가 어렵고 정맥혈 채혈의 가능성도 있으며 환자의 통증과 합병증은 커진다.However, such a blood collection method is a very subjective test method performed on the finger sensation of the medical staff, the accuracy of which varies depending on the skill of the medical staff. In other words, the lower the skill of the medical staff, the more difficult it is to find the exact location of the lumbar artery, the possibility of venous blood collection, and the more pain and complications of the patient.

도 1은 본 발명의 제1 실시예에 따른 동맥 채혈 지원 장치의 외관을 도시한 도면이다. 1 is a view showing the appearance of the arterial blood collection support apparatus according to the first embodiment of the present invention.
도 1에 도시된 바와 같이, 본 발명의 동맥 채혈 지원 장치(10)는 환자 손목에 착용 가능한 형태로 구현되어, 동맥혈 위치를 알려주는 초음파 영상을 획득 및 디스플레이한다. 이에 의료진은 본 발명의 동맥 채혈 지원 장치가 디스플레이하는 초음파 영상을 통해 환자 손목에 존재하는 동맥의 위치를 눈으로 확인하면서 동맥혈을 채취할 수 있게 된다. As shown in Figure 1, the arterial blood collection support device 10 of the present invention is implemented in a form that can be worn on the wrist of the patient, to obtain and display an ultrasound image indicating the location of arterial blood. The medical staff can collect the arterial blood while visually confirming the position of the artery present in the wrist of the patient through the ultrasound image displayed by the arterial blood collection support device of the present invention.
이하, 도 2를 참고하여 본 발명의 제1 실시예에 따른 동맥 채혈 지원 장치의 구성을 살펴보면 다음과 같다. Hereinafter, the configuration of the arterial blood collection support device according to the first embodiment of the present invention will be described with reference to FIG. 2.
도 2에 도시된 바와 같이, 본 발명의 동맥 채혈 지원 장치(10)는 환자 손목에 부착 가능한 형태로 구현된 몸체(11)와, 몸체(12)에 실장되는 초음파 프로브(12), 프로세서(13) 및 터치스크린(14)를 포함하여 구성될 수 있다. As illustrated in FIG. 2, the arterial blood collection support device 10 of the present invention includes a body 11 implemented as a form attachable to a wrist of a patient, an ultrasound probe 12 mounted on the body 12, and a processor 13. ) And the touch screen 14.
몸체(11)는 벨크로, 자동버클, 손목 밴드, 패치 및 손목 시계 형태 등과 같이 환자 신체(특히, 손목)에 부착 가능한 형태로 구현된다. 물론, 벨크로, 자동버클, 손목 밴드, 패치 및 손목 시계 형태 이외에도 환자 손목에 부착될 수 있는 범위 내에서 그 구현 형태는 다양하게 변화될 수 있을 것이다. Body 11 is implemented in a form that can be attached to the patient's body (particularly, wrist), such as Velcro, automatic buckle, wrist band, patch and wrist watch form. Of course, in addition to the Velcro, automatic buckle, wrist band, patch and wrist watch form, the implementation may be variously changed within the range that can be attached to the patient wrist.
초음파 프로브(12)는 환자 손목에 접촉되도록 몸체(11)에 실장되어, 환자 손목에 초음파를 발사하고, 환자 손목내 혈관 속에 흐르는 적혈구에 부딪혀서 되돌아오는 초음파를 수신한다. The ultrasound probe 12 is mounted on the body 11 to be in contact with the patient's wrist, emits ultrasound to the patient's wrist, and receives an ultrasound that is returned by hitting red blood cells flowing through blood vessels in the patient's wrist.
프로세서(13)는 몸체(11) 내부에 실장되어, 사용자가 초음파 검사를 요청할 때에 초음파 프로브(12)를 구동하여 초음파를 발사 및 수신하고, 수신된 초음파를 분석하여 환자 손목의 초음파 영상을 획득한 후, 터치스크린(14)을 통해 디스플레이한다. The processor 13 is mounted inside the body 11 to drive and receive an ultrasound probe 12 when the user requests an ultrasound examination, to emit and receive ultrasound, and to analyze the received ultrasound to acquire an ultrasound image of a patient's wrist. Then, the display through the touch screen 14.
특히, 본 발명의 프로세서(13)는 도플러 효과를 통해 환자 손목의 초음파 영상 내에서의 동맥혈 영역과 정맥혈 영역을 도출하고, 도3에서와 같이 동맥혈 영역에는 빨간색 화소를 정맥혈 영역에는 파란색 화소를 오버레이시킴으로써, 사용자가 이들 위치를 직관적으로 파악할 수 있도록 해준다. In particular, the processor 13 of the present invention derives the arterial blood region and the venous blood region in the ultrasound image of the patient's wrist through the Doppler effect, and overlays the red pixel on the arterial blood region and the blue pixel on the venous blood region as shown in FIG. This allows the user to intuitively identify these locations.
터치스크린(14)은 프로세서(13)에 의해 생성된 제어 메뉴를 화면 표시하고, 상기 제어 메뉴를 통해 입력되는 사용자 요청 사항을 프로세서(13)로 전달하거나, 프로세서(13)의 제어하에 환자 손목의 초음파 영상을 디스플레이한다. The touch screen 14 displays a control menu generated by the processor 13 and transmits a user request input through the control menu to the processor 13 or under the control of the processor 13. The ultrasound image is displayed.
즉, 본 발명에서는 동맥 채혈 지원 장치가 환자 손목에 장착될 수 있도록 하고, 이를 통해 환자 손목에 대응되는 초음파 영상을 획득 및 디스플레이함으로써, 전문적 지식이 없는 사람도 동맥혈의 위치를 손쉽게 파악하고 채혈할 수 있도록 하는 동맥 채혈 지원 장치를 제공하고자 한다. That is, in the present invention, the arterial blood support device can be mounted on the patient's wrist, and through this, by acquiring and displaying an ultrasound image corresponding to the patient's wrist, even a person without expert knowledge can easily grasp the location of the arterial blood and collect the blood. An arterial blood collection support device is provided.
다만, 본 발명의 동맥 채혈 지원 장치가 환자 손목에 장착되는 경우, 동맥 채혈 지원 장치는 장치 하부 영역에 위치한 피부의 초음파 영상을 획득 및 제공하는 반면, 사용자는 동맥 채혈 지원 장치가 착용되지 않는 부위의 동맥에 주사를 삽입하여 혈액을 채취하여야 하는 단점이 있다. 즉, 동맥 채혈 지원 장치의 모니터링 위치가 채혈 위치가 상이한 단점이 있다. 이에 의료진은 동맥 채혈 지원 장치를 통해 디스플레이되는 초음파 영상을 보고, 동맥 위치를 다시 유추해야 하는 번거로움이 있다. However, when the arterial blood support device of the present invention is mounted on the wrist of the patient, the arterial blood support device acquires and provides an ultrasound image of the skin located in the lower region of the device, while the user of the arterial blood support device does not wear the arterial blood support device. There is a disadvantage in that blood is collected by inserting an injection into the artery. That is, there is a disadvantage that the monitoring position of the arterial blood collection support apparatus is different from the blood collection position. Therefore, the medical staff sees the ultrasound image displayed through the arterial blood collection support device, and it is troublesome to infer the artery position again.
따라서 본 발명에서는 동맥 채혈 지원 장치를 도 4와 같이 구성하여, 동맥 채혈 지원 장치가 동맥 위치를 직접 지시해줄 수도 있도록 한다. Therefore, in the present invention, the arterial blood collection support device is configured as shown in FIG. 4 so that the arterial blood collection support device may directly indicate the artery position.
도4는 본 발명의 제2 실시예에 따른 동맥 채혈 지원 장치의 구성을 도시한 도면이다. 4 is a diagram illustrating a configuration of an arterial blood collection support device according to a second embodiment of the present invention.
도4를 참고하면, 본 발명의 동맥 채혈 지원 장치(10)는 도 2의 구성 요소들 이외에 동맥 위치를 센싱 및 통보하는 동맥 위치 센싱부(15), 및 동맥 위치 센싱부(15)에 의해 센싱된 동맥 위치에 광을 조사함으로써, 사용자에게 동맥 위치를 알려주는 동맥 위치 표시부(16)를 더 포함할 수 있음을 알 수 있다. Referring to FIG. 4, the arterial blood collection support device 10 of the present invention is sensed by the arterial position sensing unit 15 and the arterial position sensing unit 15 that sense and notify the arterial position in addition to the components of FIG. 2. By irradiating light to the artery location, it can be seen that the artery position display unit 16 for notifying the artery position to the user may be further included.
손목에 위치하는 동맥혈은 도 5에 도시된 바와 같이 직진성을 가지므로, 채혈 부위의 동맥혈과 인접 부위에 위치된 동맥혈은 서로 연결되며 서로 동일한 방향성을 가지게 된다. 따라서 채혈 인접 부위 즉, 동맥 채혈 지원 장치가 탐지한 부위의 동맥혈 위치를 안다면, 채혈 부위의 위치도 손쉽게 유추 및 안내할 수 있을 것이다. Since arterial blood located in the wrist has straightness as shown in FIG. 5, arterial blood at a blood collection site and arterial blood located at an adjacent site are connected to each other and have the same direction. Therefore, if the location of arterial blood in the adjacent area of blood collection, that is, the area detected by the arterial blood collection support device, can be easily inferred and guided.
동맥 위치 센싱부(15)는 몸체 밑면의 전면부에 진동 센서 어레이, 적외선 센서 어레이, 도플러 센서 어레이 중 적어도 하나를 배치하고, 이를 통해 동맥 위치를 센싱 및 통보하도록 한다. The artery position sensing unit 15 arranges at least one of a vibration sensor array, an infrared sensor array, and a Doppler sensor array on the front surface of the bottom of the body, thereby sensing and notifying the artery position.
만약, 본 발명의 동맥 위치 센싱부(15)가 도6의 (a)와 같이 몸체 밑면의 전면부에 일렬 배치되는 다수의 진동 센서(S1~S7)를 포함하는 진동 센서 어레이로 구현된다면, 다음과 같은 원리에 따라 동맥 위치를 센싱 및 통보할 수 있을 것이다. If the arterial position sensing unit 15 of the present invention is implemented as a vibration sensor array including a plurality of vibration sensors (S1 ~ S7) arranged in line on the front surface of the bottom of the body as shown in Figure 6 (a), The artery position may be sensed and notified according to the same principle.
심장은 박동할 때마다 동맥을 따라 혈액을 밀어낸다. 이러한 혈액의 흐름으로 인하여 동맥이 팽창과 이완을 되풀이하게 되는데 이를 맥박이라고 하며, 동맥 위 피부를 통해서는 맥박 세기에 상응하는 진동을 느낄 수 있게 된다. 이에 몸체 밑면의 전면부에 다수의 진동 센서를 일렬 배치한 후, 이들을 피부에 접촉시킨다면, 동맥이 지나가는 지점의 피부에 접촉된 진동 센서는 가장 큰 진동을 센싱하게 될 것이다. 이에 본 발명에서는 다수의 진동 센서를 통해 피부 진동을 센싱하고, 가장 큰 진동이 측정된 지점에 동맥이 위치한다고 판단하도록 한다. Each time the heart beats, it pushes blood along the arteries. This flow of blood causes the artery to expand and relax repeatedly. This is called a pulse, and the skin above the artery can feel the vibration corresponding to the pulse intensity. Therefore, if a plurality of vibration sensors are arranged in a line at the front of the bottom of the body and then contacted with the skin, the vibration sensors in contact with the skin at the point where the artery passes will sense the greatest vibration. Accordingly, in the present invention, the vibration of the skin is sensed through a plurality of vibration sensors, and the artery is determined to be located at the point where the largest vibration is measured.
한편, 동맥 위치 센싱부(15)가 도6의 (b)와 같이 몸체 밑면의 전면부에 서로 인접되도록 일렬 배치된 다수의 적외선 센서(IR1~IR7)와 다수의 도플러 센서(D1~D7)를 구비한다면, 동맥 위치 센싱부(15)는 다수의 적외선 센서(IR1~IR7)를 통해 피부로 적외선을 조사하고, 다수의 도플러 센서(D1~D7)를 통해 헤모글로빈이 흡수한 적외선을 측정하도록 한다. 그리고 적외선 측정 결과를 기반으로 산소포화도와 맥박을 산출하고, 가장 높은 산소포화도가 검출되거나, 가장 센 펄스가 검출된 지점을 동맥 위치로 획득하도록 한다. On the other hand, the artery position sensing unit 15 is a plurality of infrared sensors (IR1 ~ IR7) and a plurality of Doppler sensors (D1 ~ D7) arranged in line so as to be adjacent to each other in the front portion of the bottom of the body as shown in Figure 6 (b) If provided, the arterial position sensing unit 15 irradiates infrared rays to the skin through a plurality of infrared sensors IR1 to IR7, and measures the infrared rays absorbed by hemoglobin through the plurality of Doppler sensors D1 to D7. The oxygen saturation degree and pulse rate are calculated based on the infrared measurement result, and the point where the highest oxygen saturation degree is detected or the strongest pulse is detected is acquired as the artery position.
동맥 위치 표시부(16)는 몸체 밑면의 전면부과 접하는 몸체 측면(즉, 동맥 위치 센싱부(15)에 인접되는 몸체 측면)에 일렬 배치되는 다수의 광원(L1~L2)을 구비한다. 그리고 동맥 위치 센싱부(15)의 센싱 결과를 기반으로 다수의 광원(L1~L2) 중 하나를 턴온시킴으로써, 동맥 위치 센싱부(15)에 의해 센싱된 동맥 위치에 광이 조사되도록 한다. The artery position indicator 16 includes a plurality of light sources L1 to L2 arranged in line on the body side (ie, the body side adjacent to the artery position sensing unit 15) in contact with the front portion of the bottom of the body. Then, by turning on one of the plurality of light sources L1 to L2 based on the sensing result of the artery position sensing unit 15, the light is irradiated to the artery position sensed by the artery position sensing unit 15.
예를 들어, 동맥 위치 센싱부(15)가 7개의 진동 센서를 구비하고, 7개의 진동 센서 중 2 번째 진동 센서가 가장 큰 진동을 측정하면, 동맥 위치 표시부(16)는 두 번째 진동 센서에 대응되는 두 번째 광원을 통해 광을 조사하는 방식으로, 동맥 위치 센싱부(15)에 의해 센싱된 동맥 위치에 광이 조사되도록 해줄 수 있을 것이다. For example, if the artery position sensing unit 15 includes seven vibration sensors and the second vibration sensor among the seven vibration sensors measures the largest vibration, the artery position display unit 16 corresponds to the second vibration sensor. By irradiating light through the second light source, the light may be irradiated to the artery position sensed by the artery position sensing unit 15.
다만, 요골 동맥의 직경은 약 0.5cm 이므로, 동맥 위치 센싱부(15)의 센서간 간격과 동맥 위치 표시부(16)의 광원간 간격은 0.5cm 정도인 것이 바람직할 것이다. However, since the diameter of the radial artery is about 0.5 cm, the distance between the sensors of the artery position sensing unit 15 and the light source of the artery position display unit 16 may be about 0.5 cm.
더하여, 동맥 위치 표시부(16)의 광은 동맥 채혈 지원 장치가 미착용된 영역(예를 들어, 동맥 채혈 지원 장치의 전하방 1.5~2cm 지점)에 조사되는 것이 바람직하다. In addition, it is preferable that the light of the artery position indicator 16 is irradiated to a region where the arterial blood collecting support device is not worn (for example, 1.5 to 2 cm of the charge room of the arterial blood collecting support device).
이에 본 발명에서는 도7에 도시된 바와 같이 본 발명에서는 몸체 윗면이 몸체 밑면 보다 넓은 면적을 가지도록 다수의 광원이 배치된 몸체 측면을 경사지게 구현하도록 한다. Therefore, in the present invention, as shown in FIG. 7, in the present invention, the body side on which the plurality of light sources are disposed is inclined so as to have a larger area than the bottom of the body.
또한 필요한 경우, 몸체 측면을 경사지게 구현하는 대신, 판 형상으로 구현되며 다수의 광원(L1~L7)이 일렬 배치되는 광원 패널(미도시), 몸체 밑면의 전면부과 접하는 몸체 측면에 설치되어 상기 광원 패널(미도시)의 기울기를 자유롭게 조절하는 각도 조절 수단(미도시)을 구비하고, 사용자가 각도 조절 수단을 통해 다수의 광원의 광 조사각을 수동 제어할 수도 있도록 한다. In addition, if necessary, instead of implementing the body side inclined, it is implemented in a plate shape and a light source panel (not shown) in which a plurality of light sources (L1 ~ L7) are arranged in line, installed on the side of the body in contact with the front portion of the bottom of the light source panel It is provided with an angle adjusting means (not shown) for freely adjusting the inclination of the (not shown), and allows the user to manually control the light irradiation angle of the plurality of light sources through the angle adjusting means.
또한, 외부 환경에 의해 광 조사를 이용한 동맥 위치 안내가 어려운 경우에는, 터치 스크린의 일부 영역을 동맥 위치 안내 창으로 할당하고, 이를 통해 동맥 위치를 안내하기 위한 이미지, 텍스트 적어도 하나를 표시해주도록 한다. 즉, 본 발명에서는 동맥 위치 안내 방법을 다양화하여, 여러 가지 구동 환경에 적절히 대응할 수 있도록 한다.In addition, when it is difficult to guide the arterial position using light irradiation due to the external environment, a portion of the touch screen may be allocated to the arterial position guide window, thereby displaying at least one image or text for guiding the arterial position. That is, in the present invention, the arterial position guidance method is diversified to appropriately cope with various driving environments.
이와 같이, 본 발명의 동맥 채혈 지원 장치는 채혈이 진행되어야 할 동맥 위치를 시각적 알려줌으로써, 사용자가 동맥 채혈 지원 장치를 통해 제공되는 초음파 영상을 보고 다시 채혈 위치를 유추해야 하는 번거로움 없이 채혈 위치를 직관적으로 파악할 수 있도록 해준다. In this way, the arterial blood collection support device of the present invention visually informs the location of the artery to proceed with the blood collection, the user can see the ultrasound image provided through the arterial blood collection support device without the need to infer the blood collection location again the hassle Intuitive to understand.
즉, 본 발명에서는 환자 손목에 대응되는 초음파 영상을 제공하는 것에서 더 나아가 채혈 위치까지도 시각적으로 알려줄 수 있도록 함으로써, 전문적 지식이 없는 사람도 용이하게 채혈 동작을 수행할 수 있도록 해준다. In other words, in the present invention, by providing an ultrasound image corresponding to the wrist of the patient and further visually notifying the location of blood collection, a person without expert knowledge can easily perform the blood collection operation.
