Description

초저전력 무선전송장치를 탑재한 인슐린 펌프{Insulin pump including ultra low power wireless transmitter}[0001] The present invention relates to an insulin pump including an ultra low power wireless transmission device,

본 발명은 초저전력 무선전송장치를 탑재한 인슐린 펌프에 관한 것으로서, 보다 상세하게는 전력 소모량을 최소화할 수 있는 인슐림 펌프를 제공하는 데 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an insulin pump equipped with an ultra low power wireless transmission device, and more particularly, to an insulin pump capable of minimizing power consumption.

일반적으로 혈당(blood sugar)은 혈액 속에 함유되어 있는 포도당을 의미한다. 당뇨병은 인슐린의 분비량이 부족하거나 정상적인 기능이 이루어지지 않는 등의 대사질환의 일종으로 혈중 포도당의 농도가 높아지는 고혈당을 특징으로 하며, 고혈당으로 인하여 여러 증상 및 징후를 일으키게 된다. 당뇨병 환자의 경우 혈당 측정기를 상시 휴대하고, 주기적으로 혈당량을 체크하여 건강상태를 체크하거나 주치의에게 제공해야 한다. In general, blood sugar refers to glucose contained in the blood. Diabetes mellitus is a type of metabolic disease that lacks insulin secretion or does not function normally. It is characterized by hyperglycemia in which the concentration of glucose in the blood increases. Hyperglycemia causes various symptoms and signs. If you have diabetes, you should carry your blood glucose meter at all times, check your blood sugar regularly, check your health, or give it to your doctor.

그러나, 종래에는 환자인 사용자가 혈당량을 휴대용 혈당 측정기를 이용하여 매번 체크하여 사용하는 것이 번거로울 뿐만 아니라 체크한 혈당량을 메모해두어야 하기 때문에 사용이 불편한 문제점이 있다. However, conventionally, it is troublesome for the user, who checks and uses the blood sugar amount every time using the portable blood glucose meter, because the user who is the patient has to record the amount of the blood glucose checked, which is inconvenient to use.

최근에는 신체에 상시 착용가능한 혈당 측정기와 인슐린 펌프가 사용되고 있으나, 이러한 혈당 측정기와 인슐림 펌프의 경우 상호간에 RF(Radio Frequency)통신을 하기 때문에 전력 소모량이 큰 문제점이 있다. In recent years, blood glucose meters and insulin pumps, which can be worn on the body at all times, have been used. However, these blood glucose meters and insulin pumps have a problem of power consumption because they perform radio frequency (RF) communication with each other.

본 발명의 목적은, 전력 소모량을 최소화할 수 있는 초저전력 무선전송장치를 탑재한 인슐린 펌프를 제공하는 데 있다. An object of the present invention is to provide an insulin pump equipped with an ultra low power wireless transmission device capable of minimizing power consumption.

본 발명에 따른 초저전력 무선전송장치를 탑재한 인슐린 펌프는, 신체에 삽입되어 체액 중의 혈당을 감지하는 혈당 센서로부터 감지된 신호를 무선 통신을 통해 수신하고, 수신된 신호에 따라 상기 신체에 인슐린 주입용 니들을 통해 인슐린을 주입하도록 작동되고, 상기 무선 통신은 블루투스 4.0을 포함한다.The insulin pump equipped with the ultra low power wireless transmission device according to the present invention receives signals detected from a blood glucose sensor inserted into a body and detects blood glucose in body fluids through wireless communication and transmits insulin infusion And injects insulin through the needles, and the wireless communication includes Bluetooth 4.0.

본 발명의 다른 측면에 따른 초저전력 무선전송장치를 탑재한 인슐린 펌프는, 신체에 삽입되어 체액 중의 혈당을 감지하는 혈당 센서로부터 감지된 신호를 체내 통신을 통해 수신하고, 수신된 신호에 따라 상기 신체에 인슐린 주입용 니들을 통해 인슐린을 주입하도록 작동된다.According to another aspect of the present invention, there is provided an insulin pump equipped with an ultra low power wireless transmission device, which receives a signal sensed by a blood sugar sensor inserted in a body and detects blood glucose in body fluid through in-vivo communication, Lt; RTI ID = 0.0 > insulin < / RTI >

본 발명은 혈당 센서와 인슐린 펌프가 블루투스 4.0으로 통신함으로써, 전력소모량을 최소화시킬 수 있는 이점이 있다.The present invention is advantageous in that the blood glucose sensor and the insulin pump communicate with the Bluetooth 4.0, thereby minimizing power consumption.

또한, 본 발명은 혈당 센서와 인슐린 펌프가 신체를 매체로 한 체내 통신을 함으로써, 전력 소모량을 절감할 수 있을 뿐만 아니라 외부로의 무선 통신 간섭을 최소화할 수 있는 이점이 있다. In addition, the present invention has an advantage in that the blood glucose sensor and the insulin pump perform in-vivo communication using the body as a medium, so that power consumption can be reduced and wireless communication interference to the outside can be minimized.

도 1은 본 발명의 일 실시예에 따른 초저전력 무선전송장치를 탑재한 인슐린 펌프와 혈당 센서가 도시된 도면이다.1 is a view illustrating an insulin pump and a blood glucose sensor equipped with an ultra low power wireless transmission device according to an embodiment of the present invention.

이하, 첨부된 도면을 참조하여 본 발명의 실시예에 대해 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명의 일 실시예에 따른 초저전력 무선전송장치를 탑재한 인슐린 펌프와 혈당 센서가 도시된 도면이다.1 is a view illustrating an insulin pump and a blood glucose sensor equipped with an ultra low power wireless transmission device according to an embodiment of the present invention.

도 1을 참조하면, 본 발명에 일 실시예에 따른 인슐린 펌프(20)는 혈당 센서(10)와 블루투스(Bluetooth) 4.0으로 통신하도록 설계된다. Referring to FIG. 1, an insulin pump 20 according to an embodiment of the present invention is designed to communicate with a blood glucose sensor 10 via Bluetooth 4.0.

상기 혈당 센서(10)는 신체의 복부(2)에 삽입되어 체액의 혈당을 감지하기 위한 혈당 센서용 니들(12)이 구비된다. 상기 혈당 센서(10)에는 상기 혈당 센서용 니들(12)에서 감지된 혈당에 따라 상기 인슐린 펌프(20)로 신호를 송신하기 위한 송신 모듈(미도시)이 구비된다. 상기 송신 모듈(미도시)은 상기 블루투스 4.0으로 무선 통신할 수 있도록 구비된다. The blood glucose sensor 10 is inserted into the abdominal region 2 of the body to provide a blood glucose sensor needle 12 for sensing the blood glucose of the body fluid. The blood glucose sensor 10 is provided with a transmission module (not shown) for transmitting a signal to the insulin pump 20 according to blood glucose detected by the needle 12 for blood glucose sensor. The transmission module (not shown) is provided to wirelessly communicate with the Bluetooth 4.0.

상기 인슐린 펌프(20)에는 상기 송신 모듈(미도시)과 상기 블루투스 4.0으로 신호를 수신할 수 있는 수신 모듈(미도시)이 구비된다. The insulin pump 20 is provided with a transmitting module (not shown) and a receiving module (not shown) capable of receiving a signal from the Bluetooth 4.0.

상기 인슐린 펌프(20)는 신체의 복부(2)에 삽입되는 인슐린 주입용 니들(22)과 연결된다.The insulin pump 20 is connected to an insulin injecting needle 22 inserted into the abdomen 2 of the body.

상기와 같이 구성된 인슐린 펌프의 작동을 설명하면, 다음과 같다.The operation of the insulin pump constructed as described above will be described as follows.

상기 혈당 센서(10)에서 측정된 혈당이 미리 설정된 혈당 범위를 벗어나면, 상기 송신 모듈(미도시)을 통해 상기 인슐린 펌프(20)의 수신 모듈(미도시)로 신호를 송신한다.(Not shown) of the insulin pump 20 through the transmission module (not shown) if the blood glucose measured by the blood glucose sensor 10 is out of a preset blood sugar range.

이 때, 상기 혈당 센서(10)의 송신 모듈(미도시)과 상기 인슐린 펌프(20)의 수신 모듈(미도시)은 블루투스 4.0을 통신함으로써, 소모되는 전력량이 매우 적다. 따라서, 배터리 수명이 연장되어 유지비가 절감되고, 배터리 교체로 인한 번거로움이 최소화될 수 있다.
At this time, the transmitting module (not shown) of the blood glucose sensor 10 and the receiving module (not shown) of the insulin pump 20 communicate with the Bluetooth 4.0, thereby consuming a very small amount of power. Therefore, the battery life is prolonged, the maintenance cost is reduced, and the hassle of replacing the battery can be minimized.

한편, 본 발명의 다른 실시예에 대해 설명하면, 다음과 같다.Other embodiments of the present invention will now be described.

본 발명의 다른 실시예에 따른 인슐린 펌프는, 혈당 센서와 체내 통신을 통해 통신하는 것이 상기 일 실시예와 상이하고, 상이한 점을 중심으로 상세히 설명한다.The insulin pump according to another embodiment of the present invention is different from the above embodiment in that it communicates with the blood sugar sensor through in-vivo communication, and will be described in detail with respect to different points.

상기 혈당 센서(10)의 혈당 센서용 니들(12)과, 상기 인슐린 펌프(20)의 인슐린 주입용 니들(22)은 모두 금속으로 이루어진다. 따라서, 상기 혈당 센서용 니들(12)과 상기 인슐린 주입용 니들(22)을 전극으로 이용하여, 상기 혈당 센서(10)와 상기 인슐린 펌프(20)를 연결하고, 상기 신체 내에는 약한 고주파 반송 주파수 채널을 통하여 채널을 유지하고, 반송파에 혈당 정보 및 각종 제어 정보 등의 디지털 정보를 모듈레이션하여 송수신할 수 있다. The blood glucose sensor needle 12 of the blood glucose sensor 10 and the insulin injecting needle 22 of the insulin pump 20 are both made of metal. Therefore, the blood glucose sensor 10 and the insulin pump 20 are connected to each other using the blood glucose sensor needle 12 and the insulin injecting needle 22 as electrodes, and a weak high frequency carrier frequency The channel can be maintained through the channel, and digital information such as blood glucose information and various control information can be modulated and transmitted to the carrier wave.

따라서, 이러한 체내 통신은 일반 무선 통신에 비하여 최소의 전력이 요구되는 이점이 있을 뿐만 아니라 외부로의 무선 간섭을 최소화할 수 있는 이점이 있다.
Therefore, the intra-body communication has an advantage in that minimum power is required compared to general wireless communication, and it is advantageous in that radio interference to the outside can be minimized.

본 발명은 도면에 도시된 실시예를 참고로 설명되었으나 이는 예시적인 것에 불과하며, 본 기술 분야의 통상의 지식을 가진 자라면 이로부터 다양한 변형 및 균등한 다른 실시예가 가능하다는 점을 이해할 것이다. 따라서, 본 발명의 진정한 기술적 보호 범위는 첨부된 특허청구범위의 기술적 사상에 의하여 정해져야 할 것이다.While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
