Description

오심·구토 제어용 저주파 전기 자극 신호 발생장치Low frequency electrical stimulation signal generator for nausea and vomiting control
본 발명은 오심·구토 제어용 저주파 전기 자극 신호 발생장치에 관한 것으로서, 비화학적인 방법에 의하여 즉각적이고 조절가능하며 사용이 편리하면서도, 오용 또는 과용의 위험을 미리 방지할 수 있는 오심·구토 제어용 저주파 전기 자극 신호 발생장치에 관한 것이다.The present invention relates to a low frequency electrical stimulation signal generator for nausea and vomiting control, which is immediate, adjustable and convenient to use by a nonchemical method, and which can prevent the risk of misuse or overuse in advance. It relates to a stimulus signal generator.
임신이나 수술 후유증 또는 항암치료에 의한 부작용 등으로 반복적인 메스꺼움이나 구토 증상으로 고통을 호소하는 경우가 적지 않으며, 음주 후 숙취로 인해 두통과 메스꺼움 및 구토를 호소하기도 한다. Many patients complain of repetitive nausea or vomiting due to pregnancy, postoperative sequelae or side effects from chemotherapy, and headaches, nausea and vomiting due to hangover after drinking.
예를 들어, 입덧은 임신 초기 임부가 경험하는 메스꺼움이나 구토, 헛구역질을 의미하는데, 대개 임신 5 ~ 14주에 호소하는 증상이다. 입덧의 원인은 과학적으로 증명된 바는 없지만 융모생성호르몬(Human Chronic Gonadotropin)의 증가가 일차적 요인으로 알려져 있고, 심리적 원인과 사회적인 요인이 영향을 주는 것으로 알려져 있다. 입덧과 연관된 증상으로는 두통, 식욕상실, 수면장애, 피로, 불안, 어지러움 등이 동반될 수 있으며, 이에 따른 영양 섭취 불균형으로 탈수, 쇠약 등의 건강문제가 유발됨은 물론 장기적으로는 신생아의 체중과 건강상태에도 영향을 줄 수 있다. For example, morning sickness refers to nausea, vomiting, and nausea experienced by pregnant women early in pregnancy, usually complaining at 5-14 weeks of pregnancy. Although the cause of morning sickness has not been scientifically proven, an increase in the human chromosome hormone (Human Chronic Gonadotropin) is known as a primary factor, and psychological and social factors are known to influence. Symptoms associated with morning sickness may include headache, loss of appetite, sleep disorders, fatigue, anxiety, and dizziness.As a result of nutritional imbalances, health problems such as dehydration and weakness may occur, and in the long term, It can also affect your health.
현재 이러한 메스꺼움 및 구토를 억제하는 방법으로는 화학 조성물 즉, 약제를 이용하거나, 침술, 지압 기타 방사선 장치 등을 이용하는 등의 방법이 임시방편으로 사용되고 있는 실정이다. Currently, as a method of suppressing nausea and vomiting, a method of using a chemical composition, that is, a drug, or using acupuncture, acupressure, other radiation devices, and the like is used as a temporary measure.
전술한 방법들 중에서 화학적 약제를 이용할 경우, 특정 사람들에 대하여는 알러지 반응을 유발할 수 있는 위험성이 있기 때문에 일반적인 오심,구토 치료방법으로는 문제점이 있다. Among the aforementioned methods, when the chemical agent is used, there is a problem as a general nausea and vomiting treatment method because there is a risk of causing an allergic reaction for certain people.
침술 및 지압법은 피부를 미세한 바늘로 찌름으로써 특정 신경 및 신경 접합부를 자극시켜 생학적 효과를 발생시키는 전통적인 요법이다. 그러나, 이 경우에는, 피부에 인위적이고 반복적인 상처를 입힐 수 있으며 무엇보다 전문가인 시술자에 의하여 시술도구가 갖추어진 장소에서 시술되어야 하므로 메스꺼움이나 구토가 발생할 때마다 즉각적이고 간편한 치료가 매우 어렵다는 문제점이 있다. Acupuncture and acupressure are traditional therapies that produce biological effects by stimulating specific nerves and nerve junctions by poking the skin with fine needles.

이하, 전술한 구조를 갖는 본 발명의 일실시예에 따른 오심·구토 제어용전기 자극 신호 발생장치(1)의 작동과정을 구체적으로 설명한다. Hereinafter, an operation process of the electrical stimulation signal generator 1 for nausea and vomiting control according to an embodiment of the present invention having the above-described structure will be described in detail.
먼저, 본체(100)에 마련된 입력부(40)의 온/오프스위치(41)를 선택하여 본체(100)를 작동시킨다. 표시부(50)에는 전원공급부(60)의 충전 잔량 그리고 정상작동 여부가 표시된다. 필요한 경우, 예를 들어, 야간에 본체(100)를 작동시키고자 하는 경우라면 백라이트키(54)를 이용하여 표시부(50)의 백라이트를 작동시켜 표시부(50)를 볼 수도 있다. First, the main body 100 is operated by selecting the on / off switch 41 of the input unit 40 provided in the main body 100. The display unit 50 displays the remaining charge of the power supply unit 60 and whether or not normal operation. If necessary, for example, when the main body 100 is to be operated at night, the display unit 50 may be viewed by operating the backlight of the display unit 50 using the backlight key 54.
다음, 유닛 밴드(200)를 전달부(300) 예를 들어, 케이블을 이용하여 본체(100)에 연결한다. 유닛 밴드(200)가 본체(100)에 연결되면, 제어부(30)는 유닛 밴드(200)에 마련된 작동감지센서(270)를 통해서 연결된 유닛 밴드(200)가 정상적으로 작동하는지 여부를 확인한다. 상기 확인여부는 예를 들어, 제어부(30)에서 신호발생부(20)를 작동시켜 유닛 밴드(200)의 전극(220)으로 테스트 신호를 송신한 다음 작동감지센서(270)에서 상기 테스트 신호가 정상적으로 수신되는 경우 이를 감지하여 제어부(30)에서 정상작동으로 판단할 수 있다. Next, the unit band 200 is connected to the main body 100 using a transmission unit 300, for example, a cable. When the unit band 200 is connected to the main body 100, the controller 30 checks whether the unit band 200 connected through the operation detection sensor 270 provided in the unit band 200 is normally operated. For example, whether or not the check signal is transmitted to the electrode 220 of the unit band 200 by operating the signal generator 20 in the controller 30 and then the test signal in the operation sensor 270 is detected. If it is received normally it can be detected by the control unit 30 to determine the normal operation.
한편, 제어부(30)는 상기 정상작동 여부 확인과 동시에 유닛 밴드(200)의 타이머(230)에서 카운트된 작동시간을 추출하여 설정된 사용한계시간과 비교한다. 이를 통해, 작동시간이 사용한계시간을 초과한 경우라면 입력부(40)를 통해 작동 조작이 입력되더라도 신호발생부(20)로의 전원인가를 차단하여 작동이 이루어지지 않도록 한다. 여기서, 제어부(30)는 상기 타이머(230)의 작동시간이 사용한계시간을 초과한 경우 이를 표시부(50)를 통하여 외부에서 인지하도록 할 수 있다. Meanwhile, the controller 30 extracts the operation time counted by the timer 230 of the unit band 200 at the same time as checking the normal operation and compares it with the set usage time. Through this, if the operation time exceeds the usage time, even if the operation operation is input through the input unit 40 to cut off the power supply to the signal generator 20 so that the operation is not made. Here, the controller 30 may be externally recognized through the display unit 50 when the operation time of the timer 230 exceeds the used time.
한편, 작동시간이 사용한계시간 미만인 경우, 제어부(30)는 입력부(40)를 통한 작동 입력을 대기한다. 제어부(30)는 타이머(230)의 작동시간을 추출하여 도 3에 도시된 바와 같이, 표시부(50)에 작동시간을 표시할 수도 있다. On the other hand, if the operation time is less than the usage time, the controller 30 waits for the operation input through the input unit 40. The controller 30 may extract the operation time of the timer 230 and display the operation time on the display unit 50 as shown in FIG. 3.
이후, 사용자 또는 조작자는 유닛 밴드(200)를 사용자의 손목에 착용하게 되며, 본체(100)의 입력부(40)를 통해 유닛 밴드(200)의 강도를 변경해가면서 적절한 강도를 선택한다. 선택된 강도는 제어부(30)에 의해 표시부(50)에 표시될 수 있다. 또는, 유닛 밴드(200)에도 본체(100)의 온/오프 스위치(41) 및 강도조절키(42)에 해당하는 보조입력부(260)를 마련하여, 유닛 밴드(200)에서 사용자가 직접 조작할 수도 있음은 물론이다. Thereafter, the user or the operator wears the unit band 200 on the user's wrist, and selects an appropriate strength while changing the strength of the unit band 200 through the input unit 40 of the main body 100. The selected intensity may be displayed on the display unit 50 by the controller 30. Alternatively, an auxiliary input unit 260 corresponding to the on / off switch 41 and the intensity control key 42 of the main body 100 may be provided in the unit band 200 so that the user can directly operate the unit band 200. Of course you can.
한편, 사용자가 유닛 밴드(200) 사용시간을 미리 설정하고자 하는 경우에는 본체(100)의 내부에 자극시간을 카운트하는 타이머를 마련할 수도 있다. 이 경우, 제어부(30)는 타이머에서 카운트된 시간이 설정된 자극시간을 초과하는 경우, 자동으로 신호발생부(20)로의 전원인가를 차단할 수 있다. On the other hand, when the user wants to set the use time of the unit band 200 in advance may be provided with a timer for counting the stimulation time inside the main body 100. In this case, when the time counted by the timer exceeds the set stimulus time, the controller 30 may automatically cut off the power supply to the signal generator 20.
한편, 유닛 밴드(200)는 체온센서(240) 또는 맥박센서(250)를 더 구비할 수 있는 바, 사용 중에 필요에 따라 사용자의 체온 또는 맥박을 측정하여 이를 표시부(50)에 표시할 수 있다.Meanwhile, the unit band 200 may further include a body temperature sensor 240 or a pulse sensor 250. The unit band 200 may measure a user's body temperature or pulse as needed during use and display the same on the display unit 50. .
