Description

피에조 소자를 이용한 입출력 방법 및 알람 장치Input/output method and alarm device using piezo element
본 발명의 실시예들은 피에조 소자를 이용한 입출력 방법 및 알람 장치에 관한 것이다.Embodiments of the present invention relate to an input/output method and an alarm device using a piezo element.
피에조 소자(piezo element)는 압력이 인가되면 전압을 발생시키는 압전 효과 및 전압이 인가되면 진동 또는 음향이 출력되는 역압전 효과를 구현할 수 있는 장치이다. 보다 구체적으로, 피에조 부저(piezo buzzer)는 압전 소자로 이루어진 장치로서, 전압이 인가되면 진동을 통해 음향을 출력할 수 있는 음향 출력 장치로서 널리 사용되고 있다.A piezo element is a device capable of implementing a piezoelectric effect that generates voltage when pressure is applied and an inverse piezoelectric effect that generates vibration or sound when voltage is applied. More specifically, a piezo buzzer is a device made of a piezoelectric element, and is widely used as a sound output device capable of outputting sound through vibration when a voltage is applied.
한편, 신체 내의 기능이 정상적으로 동작하지 않는 경우 외부에서 약물의 주입이 필요하고, 예를 들면 당뇨병 등과 같이 혈당 수치가 조절이 안되는 경우 외부에서의 약물 주입이 필요할 수 있다. 이에 약액 주입 장치가 사용되고 있다.On the other hand, external drug injection is required when functions within the body do not operate normally, and external drug injection may be required when blood glucose levels are not controlled, such as diabetes. Accordingly, a drug solution injection device is used.
약액 주입 장치와 같이 사용자의 인체에 부착되는 의료기기는 방수를 위해 플라스틱 커버로 덮여 있을 수 있다. 따라서 약액 주입 장치에의 피에조 부저와 같은 음향 출력 기기 역시 커버 내부에 존재할 수 있다.A medical device attached to a user's body, such as a drug injection device, may be covered with a plastic cover for waterproofing. Accordingly, an audio output device such as a piezo buzzer of the liquid injection device may also be present inside the cover.
일반적으로 인슐린 주입 장치와 같은 약액 주입 장치는 환자의 몸 안에 약액을 주입하기 위해 사용된다. 이러한 약액 주입 장치는 의사나 간호사와 같은 전문 의료진에 의해 사용되기도 하지만, 대부분의 경우 환자 자신 또는 보호자와 같은 일반인에 의해 사용되고 있다. In general, a drug solution injection device such as an insulin injection device is used to inject a drug solution into a patient's body. Such a liquid injection device is also used by professional medical personnel such as doctors and nurses, but in most cases, it is used by ordinary people such as patients themselves or their guardians.
당뇨 환자 특히, 소아 당뇨 환자의 경우에는 인슐린과 같은 약액을 정해진 간격을 두고 인체에 주입할 필요가 있다. 일정한 기간 동안 인체에 부착하여 사용하는 패치 형태의 약액 주입 장치가 개발되고 있으며, 이러한 약액 주입 장치는 환자의 복부 또는 허리 등의 인체에 일정한 기간 동안 패치 형태로 부착한 상태로 사용될 수 있다.In the case of a diabetic patient, especially a pediatric diabetic patient, it is necessary to inject a drug solution such as insulin into the human body at regular intervals. A drug injection device in the form of a patch attached to the human body for a certain period of time is being developed, and this drug injection device can be used while being attached to the body such as the abdomen or waist of a patient for a certain period of time.
약액 주입을 통한 효과의 증대를 위하여 약액 주입 장치는 약액을 환자의 몸에 정밀하게 주입하는 것이 제어될 필요가 있는데, 소형의 약액 주입 장치를 통하여 소량의 약액을 정밀하게 주입하는 것이 중요하다. In order to increase the effect through drug injection, the drug injection device needs to control the precise injection of the drug into the patient's body, and it is important to precisely inject a small amount of the drug through the small drug injection device.
약액 주입 장치는 인체에 부착될 경우 착용감이 우수하고 사용이 편리하며 내구성이 뛰어나고 저전력으로 구동될 필요성이 있다. 특히, 약액 주입 장치는 환자가 직접 피부에 부착되어 사용되므로, 사용자가 편리하고 안전하게 약액 주입 장치를 구동하는 것이 중요하다.When attached to the human body, the drug injection device needs to be comfortable to wear, convenient to use, durable, and driven with low power. In particular, since the drug injection device is used by being directly attached to the patient's skin, it is important for the user to drive the drug injection device conveniently and safely.
약액 주입 장치에는 사용자에게 경고나 주의를 전달하기 위한 알람 장치가 내장되는데, 음향 부품을 포함하는 알람 장치의 경우 진동판이 적용되어 있으며, 알람 소리를 효율적으로 전달하기 위한 공명 공간을 가질 수 있다. An alarm device for delivering a warning or caution to a user is built into the drug injection device. In the case of an alarm device including an acoustic component, a diaphragm is applied and may have a resonance space for efficiently delivering an alarm sound.
한편, 약액 주입 장치는 의료 장치이므로 멸균 공정이 필수적으로 요구되고, 멸균 공정에서 약액 주입 장치에 진공 및 가압이 반복적으로 가해질 수 있다.Meanwhile, since the drug injection device is a medical device, a sterilization process is essentially required, and vacuum and pressure may be repeatedly applied to the drug injection device during the sterilization process.
종래 알람 장치에 구비되는 공명 공간이 폐쇄적으로 닫힌 공간으로 형성됨으로 인하여 진공 및 가압이 이루어지는 멸균 공정에서 진동판이 변형되며 알람 시 음량이 저하되는 문제점이 있었다.Due to the resonant space provided in the conventional alarm device being formed as a closed space, the diaphragm is deformed in a sterilization process in which vacuum and pressurization are performed, and there is a problem in that the volume of the alarm is lowered.
본 발명이 해결하고자 하는 과제는 피에조 소자를 이용한 입출력 방법 및 알람 장치를 제공하는 데 있다.An object to be solved by the present invention is to provide an input/output method and an alarm device using a piezo element.
또한, 공명 공간의 내측과 외측 사이를 유동할 수 있는 유로부가 형성됨으로 인하여 진공 및 가압 상태를 반복하는 멸균 공정에서 알람 장치에 구비되는 진동부의 형상이 변형되는 것을 방지하고 알람 성능을 향상시킬 수 있는 약액 주입 장치를 제공한다.In addition, due to the formation of a flow path capable of flowing between the inside and outside of the resonance space, the shape of the vibration unit provided in the alarm device is prevented from being deformed in the sterilization process of repeating vacuum and pressurized conditions, and the alarm performance can be improved. A drug solution injection device is provided.

더불어, 본 발명의 일 실시예에 의하면 피에조 소자(1110)는 압력이 가해지면 전압을 발생시킬 수 있다. 즉, 피에조 소자(1110)는 압력을 가함으로서 전압이 발생되는 압전 효과를 발생시킬 수 있는 장치이다. 본 발명의 일 실시예에 의하면, 피에조 소자(1110)는 압전 효과 및 역압전 효과를 동시에 가질 수 있으므로 음향 출력 장치로 사용되는 동시에 사용자 입력을 수신할 수도 있다.In addition, according to an embodiment of the present invention, the piezo element 1110 can generate a voltage when pressure is applied.

In addition, the piezo element 1110 may include a first lead wire contact portion 1113 and a second lead wire contact portion 1114 .

The first and second lead wire contact parts 1113 are not necessarily provided at the positions shown in FIG. 4 , and their positions may be modified without limitation as long as they are positions where voltage measurement and sound output of the piezo element 1110 are possible.
본 발명의 일 실시예에 따르면, 피에조 소자(1110)의 공진 주파수는 4.0 ± 0.5(KHz), 공진 임피던스는 400(Ω)이하, 1KHz에서의 커패시턴스는 20000 ± 30 %(pF), 금속판(1111) 지름은 φ27.0 ± 0.2(mm), 세라믹판(1112) 지름은 φ20.0 ± 0.5(mm) 일 수 있으나, 반드시 이와 같은 세부 사항에 한정되지 않는다. 더불어, 금속판(1111)의 재질은 황동일 수 있으나 역시 이에 한정되지 않는다.

In addition, the thickness of the piezo element can be variously set from 0.4 mm to 0.1 mm.
도 5 은 본 발명의 일 실시예에 따른 피에조 소자를 포함하는 알람 장치의 단면을 예시한 도면이다.5 is a diagram illustrating a cross section of an alarm device including a piezo element according to an embodiment of the present invention.
상술한 바와 같이, 약액 주입 장치(1000)의 커버면(11s)의 내측에 알람 장치(1100)의 피에조 소자(1110)가 존재할 수 있다. 커버면(11s)는 상술한 약액 주입 장치(1000)의 커버하우징(11)의 영역 중 본 발명의 알람 장치(1100)에 대응하는 영역을 도시한 것이다. 커버면(11s)는 외부에서 압력이 가해졌을 때 변형이 가능한 연성 재질일 수 있다. 즉, 커버면(11s)는 기설정된 탄성 한도를 가지고 있고, 탄성 한도 내의 외부 압력이 가해지는 경우 파괴되지 않고 늘어날 수 있다. 또한, 커버면(11s)는 기설정된 탄성 한도 내의 외부 압력이 가해지는 경우 해당 외부 압력이 제거되었을 때 다시 원래의 형태로 돌아올 수 있다. 커버면(11s)의 재질로서 플라스틱, 고무, 섬유 등 연성이 우수한 재질의 물질이 제한 없이 사용될 수 있다.As described above, the piezo element 1110 of the alarm device 1100 may be present inside the cover surface 11s of the drug injection device 1000 . The cover surface 11s shows an area corresponding to the alarm device 1100 of the present invention among the areas of the cover housing 11 of the liquid injection device 1000 described above. The cover surface 11s may be made of a flexible material capable of being deformed when pressure is applied from the outside. That is, the cover surface 11s has a predetermined elastic limit, and can be stretched without breaking when an external pressure within the elastic limit is applied. In addition, when an external pressure within a predetermined elastic limit is applied to the cover surface 11s, it may return to its original shape when the external pressure is removed. As the material of the cover surface 11s, materials having excellent ductility such as plastic, rubber, and fiber may be used without limitation.
추가적인 실시예에 따르면, 상술한 도 2a의 커버면(11s)가 연성을 가진 재질이라는 특성은 약액 주입 장치(1000)의 전체 커버하우징(11) 중 알람 장치(1100)에 대응하는 영역에만 적용될 수 있다. 즉, 약액 주입 장치(1000)의 커버하우징(11)의 전체 영역이 연성을 가지지 않고, 일부 영역의 커버면(11s)만 연성을 가질 수 있다. 이는, 외부 압력에 의해 피에조 소자(1110)의 변형이 발생하기 위해서는 알람 장치(1100)에 대응하는 영역에만 커버면(11s)의 변형이 발생하면 되기 때문이다.According to an additional embodiment, the characteristic that the cover surface 11s of FIG. 2A is made of a ductile material can be applied only to an area corresponding to the alarm device 1100 among the entire cover housing 11 of the liquid injection device 1000. there is. That is, the entire area of the cover housing 11 of the drug solution injection device 1000 may not have ductility, but only a portion of the cover surface 11s may have ductility. This is because the deformation of the cover surface 11s only needs to occur in the region corresponding to the alarm device 1100 in order for the piezo element 1110 to be deformed by external pressure.
계속하여, 도 5를 참조하면 커버면(11s)와 피에조 소자(1110)의 사이에는 빈 공간(1110a)이 존재한다. 빈 공간(1110a)은 압력이 커버면(11s)에 인가되었을 때 압력이 피에조 소자(1110)에 직접적으로 인가되지 않도록 하는 완충 역할을 할 수 있다. 본 발명의 일 실시예에 의하면 빈 공간(1110a)은 일반 공기가 들어있는 공간일 수 있지만 다른 실시예에 의하면 별도의 기체 또는 액체가 충진된 공간일 수 있다. 혹은, 다른 실시예에 의하면 커버면(11s)와 피에조 소자(1110)는 밀착될 수 있다.Continuing to refer to FIG. 5 , an empty space 1110a exists between the cover surface 11s and the piezo element 1110 . The empty space 1110a may serve as a buffer to prevent pressure from being directly applied to the piezo element 1110 when pressure is applied to the cover surface 11s. According to one embodiment of the present invention, the empty space 1110a may be a space containing general air, but according to another embodiment, it may be a space filled with a separate gas or liquid. Alternatively, according to another embodiment, the cover surface 11s and the piezo element 1110 may be in close contact.
또한, 빈 공간(1110a)은 피에조 소자(1110)와 커버면(11s)를 연결하는 지지대(1117)에 의해 생성될 수 있다. 지지대(1117)는 커버면(11s)에 피에조 소자(1110)가 고정될 수 있도록 하는 부재로서, 플라스틱 또는 금속 등 다양한 재질이 지지대(1117)로서 사용될 수 있다. 더불어, 지지대(1117)가 피에조 소자(1110)를 고정하는 다양한 방법에 따라 접착제, 테이프, 나사 등의 부수 자재가 고정을 위해 추가적으로 사용될 수 있다. 도 5에서는 비록 지지대(1117)의 형태가 직선 또는 평평한 면인 것을 예시하였지만, 적절히 피에조 소자(1110)를 고정할 수 있다면 다양한 형태로 변형될 수 있다.In addition, the empty space 1110a may be created by the support 1117 connecting the piezo element 1110 and the cover surface 11s. The support 1117 is a member for fixing the piezo element 1110 to the cover surface 11s, and various materials such as plastic or metal may be used as the support 1117. In addition, according to various methods in which the support 1117 fixes the piezo element 1110, auxiliary materials such as adhesive, tape, and screws may be additionally used for fixing. Although FIG. 5 illustrates that the shape of the support 1117 is a straight line or a flat surface, it can be transformed into various shapes if the piezo element 1110 can be properly fixed.
더불어, 도 5 를 참조하면 피에조 소자(1110)는 제1 리드선(1115) 및 제2 리드선(1116)과 연결된 것을 알 수 있다. 제1 및 제2 리드선(1115, 1116)는 상술한 프로세서(1120)에 연결되어 있으며, 프로세서(1120)에 출력 신호를 전달하거나 프로세서(1120)로부터 입력 신호를 수신할 수 있다. 보다 상세히, 제1 및 제2 리드선(1115, 1116)의 재질은 도체이고, 따라서 프로세서(1120)의 전압 측정부(1123)는 리드선에 인가된 전압을 측정할 수 있다. 제1 및 제2 리드선(1115, 1116)의 형태는 도 5에 도시된 바와 같은 직선 형태 외에, 스프링 형태 등 다양하게 변형될 수 있다. 이하의 명세서에서는, 설명의 편의를 위하여 제1 및 제2 리드선(1115, 1116)을 통칭하여 리드선이라 할 수 있다.In addition, referring to FIG. 5 , it can be seen that the piezo element 1110 is connected to the first lead wire 1115 and the second lead wire 1116 . The first and second lead wires 1115 and 1116 are connected to the above-described processor 1120 and may transmit an output signal to the processor 1120 or receive an input signal from the processor 1120 . In more detail, the material of the first and second lead wires 1115 and 1116 is a conductor, and thus the voltage measuring unit 1123 of the processor 1120 may measure the voltage applied to the lead wires. The shape of the first and second lead wires 1115 and 1116 may be modified in various ways, such as a spring shape, in addition to a straight shape as shown in FIG. 5 . In the following specification, for convenience of description, the first and second lead wires 1115 and 1116 may be collectively referred to as lead wires.
도 6 은 본 발명의 일 실시예에 따라 변형된 피에조 소자를 예시한 도면이다.6 is a diagram illustrating a modified piezo element according to an embodiment of the present invention.
도 6 은 도 5의 변형예로서, 도 5 와 중복되는 구성에 대해서는 설명을 생략하기로 한다. 도 6 을 참조하면, 외부 압력(P)에 의해 커버면(11s) 및 피에조 소자(1110)의 변형이 발생할 수 있다. 피에조 소자(1110)의 변형에 의해 제1 리드선(1115) 또는 제2 리드선(1116)에는 양전압 또는 음전압이 인가될 수 있다. 또한, 외부 압력(P)이 사라지면 커버면(11s) 및 피에조 소자(1110)는 도 5 와 같은 원래의 모양으로 회복될 수 있다.FIG. 6 is a modified example of FIG. 5 , and descriptions of components overlapping those of FIG. 5 will be omitted. Referring to FIG. 6 , deformation of the cover surface 11s and the piezo element 1110 may occur due to external pressure P. A positive voltage or a negative voltage may be applied to the first lead wire 1115 or the second lead wire 1116 due to the deformation of the piezo element 1110 . In addition, when the external pressure P disappears, the cover surface 11s and the piezo element 1110 can be restored to their original shapes as shown in FIG. 5 .
본 발명의 일 실시예에 따르면, 도 5 와 같이 피에조 소자(1110)는 변형 상태로서 일반 상태 또는 눌림 상태를 가질 수 있다. 보다 상세히, 피에조 소자(1110)의 변형이 일어나지 않은 상태를 일반 상태(회복 상태), 도 6 과 같이 외부 압력(P)에 의해 피에조 소자(1110)의 변형이 일어난 상태를 눌림 상태이라 칭할 수 있다. 일 실시예에서, 사용자 알람 장치(1100)는 피에조 소자(1110)에 접촉한 리드선에 발생되는 전압을 참조하여 피에조 소자(1110)의 변형 상태로서 눌림 상태와 일반 상태를 구분할 수 있다.According to an embodiment of the present invention, as shown in FIG. 5 , the piezo element 1110 may have a normal state or a pressed state as a deformed state. In more detail, a state in which the piezo element 1110 is not deformed may be referred to as a normal state (recovery state), and a state in which the piezo element 1110 is deformed by an external pressure P as shown in FIG. 6 may be referred to as a pressed state. . In one embodiment, the user alarm device 1100 may distinguish a pressed state and a normal state as a deformation state of the piezo element 1110 by referring to a voltage generated in a lead wire contacting the piezo element 1110 .
보다 상세히, 도 5 과 같은 피에조 소자(1110)의 변형 상태가 일반 상태인 경우 리드선에는, 도 6 와 같은 눌림 상태와 비교할 때 다른 극(極)의 전압이 발생하거나 같은 극의 전압이되 절대값이 낮은 전압이 발생할 수 있다. 예를 들어, 도 6의눌림 상태에서 리드선에 음전압이 발생되는 경우, 도 5의 일반 상태에서는 양전압 또는 눌림 상태 음전압보다 높은 전압이 발생될 수 있다. 또 다른 예로서, 도 6의눌림 상태에서 리드선에 양전압이 발생되는 경우, 도 5의 일반 상태에서는 음전압 또는 눌림 상태 양전압보다 낮은 전압이 발생할 수 있다.More specifically, when the deformation state of the piezo element 1110 as shown in FIG. 5 is a normal state, a voltage of a different pole is generated in the lead wire compared to the pressed state as shown in FIG. 6, or the voltage of the same pole is an absolute value This low voltage can occur. For example, when a negative voltage is generated in the lead wire in the pressed state of FIG. 6 , a positive voltage or a voltage higher than the negative voltage in the pressed state may be generated in the normal state of FIG. 5 . As another example, when a positive voltage is generated in the lead wire in the pressed state of FIG. 6 , a voltage lower than a negative voltage or a positive voltage in the pressed state may be generated in the normal state of FIG. 5 .
본 발명의 일 실시예에 따르면, 피에조 소자(1110)의 리드선은 상술한 도 3 의 프로세서(1120)와 연결될 수 있다. 본 발명의 일 실시예에 따르면 프로세서(1120)는 피에조 소자(1110)를 제어하는 역할을 하며, 피에조 소자(1110)가 음향을 출력하거나 사용자 입력을 획득하는 동작을 제어할 수 있다. 프로세서(1120)는 마이크로 제어기(Micro Control Unit, MCU)의 일종일 수 있다. 이하의 설명에서는 프로세서(1120)의 동작에 대해 보다 상세히 살펴보기로 한다.According to an embodiment of the present invention, the lead wire of the piezo element 1110 may be connected to the above-described processor 1120 of FIG. 3 . According to an embodiment of the present invention, the processor 1120 serves to control the piezo element 1110, and may control an operation of the piezo element 1110 outputting a sound or acquiring a user input. The processor 1120 may be a type of micro control unit (MCU). In the following description, the operation of the processor 1120 will be described in more detail.
도 7 은 일 실시예에 따른 프로세서의 내부 구성을 블록도로 나타낸 것이다.7 is a block diagram illustrating an internal configuration of a processor according to an exemplary embodiment.
도 7을 참조하면, 일 실시예에 따른 알람 장치(1100)의 프로세서(1120)는 제어부(1121), 음향 출력부(1122), 전압 측정부(1123), 입력 판단부(1124) 및 정상 동작 판단부(1125)를 포함할 수 있다.Referring to FIG. 7 , the processor 1120 of the alarm device 1100 according to an embodiment includes a control unit 1121, an audio output unit 1122, a voltage measurement unit 1123, an input determination unit 1124, and a normal operation. A determination unit 1125 may be included.
먼저, 제어부(1121)는 알람 장치(1100)의 전반적인 동작을 결정하고 제어한다. 보다 상세히, 제어부(1121)는 피에조 소자(1110)의 입출력 상태를 음향 출력 상태와 입력 확인 상태 중 하나로 결정한다. 제어부(1121)는 피에조 소자(1110)의 상태를 음향 출력 상태로 결정한 경우 음향 출력부(1122)에 제어 명령을 전달하고, 입력 확인 상태로 결정한 경우 전압 측정부(1123)로부터 리드선에 발생된 전압값을 수신한다.First, the controller 1121 determines and controls the overall operation of the alarm device 1100 . In more detail, the control unit 1121 determines the input/output state of the piezo element 1110 as one of a sound output state and an input confirmation state. The control unit 1121 transmits a control command to the audio output unit 1122 when the state of the piezo element 1110 is determined to be in the audio output state, and when it is determined to be in the input check state, the voltage generated in the lead wire from the voltage measuring unit 1123 receive the value
보다 구체적으로, 음향 출력부(1122)는 피에조 소자(1110)로 하여금 음향 출력을 할 수 있도록 음향 출력 신호를 피에조 소자(1110)로 송출한다. 이때, 음향 출력 신호는 피에조 소자(1110)에 전압으로 인가되어 피에조 소자(1110)의 역압전효과를 생성함으로서, 피에조 소자(1110)가 음향을 출력할 수 있도록 한다. 본 발명의 일 실시예에 의하면 음향 출력부(1122)는 PWM(Pulse Width Modulation) 방법을 이용하여 음향을 출력할 수 있다. 즉, 음향 출력부(1122)는 프로세서(1120)에 내장된 클락을 이용하여 일정한 주기 내에서 듀티(duty)의 비를 변화시켜 전압을 제어함으로써, 피에조 소자(1110)에 인가되는 전압을 제어할 수 있다.More specifically, the audio output unit 1122 transmits an audio output signal to the piezo device 1110 so that the piezo device 1110 can output audio. At this time, the sound output signal is applied as a voltage to the piezo element 1110 to generate an inverse piezoelectric effect of the piezo element 1110, so that the piezo element 1110 can output sound. According to an embodiment of the present invention, the sound output unit 1122 may output sound using a PWM (Pulse Width Modulation) method.

한편, 본 발명의 다른 실시예에 따르면, 제어부(1121)는 음향 출력부(1122)로 출력 제어 신호를 송출하되, 해당 출력 제어 신호는 피에조 소자(1110)로 하여금 음향 출력이 아니라 진동 출력을 발생시키는 것일 수 있다. 상술한 바와 같이 피에조 소자(1110)는 역압전 효과를 일으킬 수 있는 소자로서, 전압이 인가되면 진동을 발생시켜 음향을 출력할 수 있다. 따라서 피에조 소자(1110)는 인가된 전압에 따라 음향 출력이 아닌 진동 출력을 발생시키는 것이 가능하다. 이에 본 발명의 일 실시예에 따르면, 음향 출력부(1122)는 제어부(1121)로부터의 제어 명령에 의해 피에조 소자(1110)를 진동시킬 수 있다.Meanwhile, according to another embodiment of the present invention, the control unit 1121 transmits an output control signal to the sound output unit 1122, but the output control signal causes the piezo element 1110 to generate vibration output instead of sound output. it may be to As described above, the piezo element 1110 is an element that can cause an inverse piezoelectric effect, and can generate sound by generating vibration when a voltage is applied. Therefore, the piezo element 1110 can generate vibration output rather than sound output according to the applied voltage.

먼저, 도 8을 참조하면 프로세서(1120)는 현재 피에조 소자(1110)의 입출력 상태가 현재 음향 출력 상태인지 여부를 판단한다(S10). 피에조 소자(1110)가 현재 음향 출력 중인 경우(Y), 프로세서(1120)는 피에조 소자(1110)의 상태를 음향 출력 상태로 결정하면서 기설정된 주기로 음향 출력 여부를 계속하여 확인한다. First, referring to FIG. 8 , the processor 1120 determines whether the input/output state of the piezo element 1110 is the current sound output state (S10). When the piezo element 1110 is currently outputting sound (Y), the processor 1120 determines whether the piezo element 1110 is in a sound output state and continuously checks whether sound is output at a preset cycle.
프로세서(1120)가 현재 피에조 소자(1110)가 음향 출력 중이 아니라고 판단하는 경우(N), 프로세서(1120)는 피에조 소자(1110)의 상태를 입력 확인 상태로 판단하고, 입력 확인 상태로 진입(S20)한다.When the processor 1120 determines that the piezo element 1110 is not currently outputting sound (N), the processor 1120 determines the state of the piezo element 1110 as an input check state and enters the input check state (S20). )do.
본 발명의 일 실시예에 따르면, 입력 확인 상태로 진입(S20)한 후에도, 기설정된 조건을 만족하는 경우 프로세서(1120)는 현재 피에조 소자(1110)의 입출력 상태를 다시 음향 출력 상태(S10)로 결정할 수 있다. 일 실시예에 따르면, 음향 출력 상태를 결정하는 기설정된 조건은 음향 출력 여부로서, 프로세서(1120)는 입력 확인 상태 중에도 음향 출력이 감지되면 피에조 소자(1110)의 입출력 상태를 음향 출력 상태로 결정할 수 있다. 다른 실시예에 따르면, 음향 출력 상태를 결정하는 기설정된 조건은 시간 초과 여부로서, 프로세서(1120)는 입력 확인 상태인 채로 기설정된 시간을 경과하는 경우 피에조 소자(1110)의 상태를 음향 출력 상태로 결정할 수 있다. 또 다른 실시예에 따르면, 음향 출력 상태를 결정하는 기설정된 조건은 음향 출력 판단 횟수로서, 프로세서(1120)는 기설정된 음향 출력 판단 횟수를 초과하는 경우 피에조 소자(1110)의 상태를 음향 출력 상태를 결정할 수 있다.According to an embodiment of the present invention, even after entering the input check state (S20), when a predetermined condition is satisfied, the processor 1120 returns the current input/output state of the piezo element 1110 to the sound output state (S10). can decide According to an embodiment, a preset condition for determining the sound output state is whether or not sound is output, and the processor 1120 may determine the input/output state of the piezo element 1110 as the sound output state when the sound output is detected even during the input checking state. there is. According to another embodiment, a predetermined condition for determining the audio output state is whether a time has elapsed, and the processor 1120 changes the state of the piezo element 1110 to the audio output state when a predetermined time elapses while remaining in the input checking state. can decide According to another embodiment, the preset condition for determining the sound output state is the number of times of sound output determination, and the processor 1120 changes the state of the piezo element 1110 to the sound output state when the preset number of times of sound output determination is exceeded. can decide
도 9는 본 발명의 일 실시예에 따라 피에조 소자가 입출력 상태가 입력 확인 상태인 경우 프로세서의 동작을 시계열적으로 나타낸 도면이다.9 is a time-sequential diagram showing operations of a processor when an input/output state of a piezo element is an input check state according to an embodiment of the present invention.
도 9 를 참조하면, 먼저 프로세서(1120)는 전압을 측정한다(S21). 상술한 바와 같이, 피에조 소자(1110)의 변형 상태가 일반 상태에서 눌림 상태로 변경되는 경우 전압이 변경되므로, 사용자의 입력을 확인하기 위해 피에조 소자(1110)의 리드선에 발생된 전압을 측정할 수 있다. 또한, 다른 일 실시예에 따르면, 프로세서(2100)는 정전기 터치 소자에 의해 발생된 전압을 측정할 수 있다. Referring to FIG. 9 , the processor 1120 first measures the voltage (S21). As described above, since the voltage is changed when the deformation state of the piezo element 1110 is changed from the normal state to the pressed state, the voltage generated in the lead wire of the piezo element 1110 can be measured to confirm the user's input. there is. Also, according to another embodiment, the processor 2100 may measure a voltage generated by an electrostatic touch element.
다음으로, 프로세서(1120)는 측정된 전압과 기준전압을 비교한다(S22). 본 발명의 일 실시예에서, 기준 전압이 음전압인 경우, 즉 피에조 소자(1110)가 일반(회복) 상태일 때 리드선에 음전압이 발생되는 경우, 프로세서(1120)는 측정 전압이 기준전압보다 큰지 여부를 판단한다(측정전압>기준전압). 즉, 프로세서(1120)는 측정 전압이 양전압이거나 혹은 기준 전압보다 절대값이 큰지 여부를 판단한다.Next, the processor 1120 compares the measured voltage with the reference voltage (S22). In one embodiment of the present invention, when the reference voltage is a negative voltage, that is, when a negative voltage is generated in the lead wire when the piezo element 1110 is in a normal (recovery) state, the processor 1120 determines that the measured voltage is higher than the reference voltage. Determine whether it is large (measurement voltage > reference voltage). That is, the processor 1120 determines whether the measured voltage is a positive voltage or has an absolute value greater than that of the reference voltage.
이때, [측정전압>기준전압]인 경우(N), 프로세서(1120)는 현재 피에조 소자(1110)의 변형 상태가 눌림 상태라고 판단하고, 사용자 입력이 존재하는 입력 상태라고 인식한다(S23). 만약 [측정전압>기준전압]이 아닌 경우(Y), 프로세서(1120)는 현재 피에조 소자(1110)의 변형 상태가 일반(회복) 상태라고 판단하고, 프로세서(1120)는 기설정된 주기로 계속하여 리드선에 발생된 전압을 측정한다(S21).At this time, in the case of [measured voltage>reference voltage] (N), the processor 1120 determines that the current deformation state of the piezo element 1110 is a pressed state and recognizes it as an input state in which a user input exists (S23). If it is not [measured voltage > reference voltage] (Y), the processor 1120 determines that the current deformation state of the piezo element 1110 is a normal (recovery) state, and the processor 1120 continues with the lead wire at a preset cycle. The voltage generated in is measured (S21).
본 발명의 다른 실시예에서, 기준 전압이 양전압인 경우, 즉 피에조 소자(1110)의 변형 상태가 일반 상태일 때 리드선에 양전압이 발생되는 경우, 프로세서(1120)는 측정 전압이 기준전압보다 작은지 여부를 판단한다(측정전압<기준전압). 즉, 프로세서(1120)는 측정 전압이 음전압이거나 혹은 기준 전압보다 절대값이 작은지 여부를 판단한다.In another embodiment of the present invention, when the reference voltage is a positive voltage, that is, when a positive voltage is generated in the lead wire when the deformation state of the piezo element 1110 is in a normal state, the processor 1120 determines that the measured voltage is higher than the reference voltage. Determine whether it is small (measurement voltage < reference voltage). That is, the processor 1120 determines whether the measured voltage is a negative voltage or an absolute value smaller than the reference voltage.
이때, [측정 전압<기준전압]인 경우(N), 프로세서(1120)는 현재 피에조 소자(1110)의 변형 상태가 눌림 상태라고 판단하고, 사용자 입력이 존재하는 입력 상태라고 인식한다(S23). 만약 [측정 전압<기준전압]이 아닌 경우(Y), 프로세서(1120)는 기설정된 주기로 계속하여 리드선에 발생된 전압을 측정한다(S21).At this time, in the case of [measured voltage<reference voltage] (N), the processor 1120 determines that the current deformation state of the piezo element 1110 is a pressed state and recognizes it as an input state in which a user input exists (S23). If it is not [measured voltage<reference voltage] (Y), the processor 1120 continuously measures the voltage generated in the lead line at a predetermined cycle (S21).
다음으로, 프로세서(1120)는 피에조 소자의 변형 상태가 눌림 상태인 경우, 인식된 입력 상태가 어떤 사용자 입력 조건을 만족하는지 확인하여 사용자 입력값을 판단한다(S24). 보다 상세히, 프로세서(1120)는 서로 다른 사용자 입력 조건을 만족하는지에 인식된 입력 상태를 분류하여 사용자 입력값을 판단할 수 있다.Next, when the deformation state of the piezo element is a pressed state, the processor 1120 checks which user input condition the recognized input state satisfies to determine a user input value (S24). In more detail, the processor 1120 may determine the user input value by classifying input states recognized as satisfying different user input conditions.
본 발명의 일 실시예에 따르면, 제1 사용자 입력 조건은 피에조 소자(1110)의 변형 상태가 일반 상태에서 눌림 상태로 변경되는 것, 즉 사용자가 피에조 소자(1110)를 한번 꾹 누른 것일 수 있다. 다른 실시예에 따르면 제2 사용자 입력 조건은 피에조 소자(1110)의 변형 상태가 일반 상태에서 눌림 상태로, 그리고 다시 일반 상태로 변경되는 것으로, 즉 사용자가 피에조 소자(1110)를 한번 눌렀다 손을 뗀 것일 수 있다. 다른 실시예에 따르면, 제3 사용자 입력 조건은 제1 사용자 입력 조건 또는 제2 사용자 입력 조건을 기설정된 횟수만큼 반복하는 것일 수 있다. 이와 같이, 프로세서(1120)는 각 사용자 입력 조건에 따른 사용자 입력값을 달리 결정함으로써 사용자 입력값에 대응하는 신호도 달리 생성할 수 있다. 이로써, 본 발명은 사용자 입력 조건에 따라 사용자 입력의 종류를 달리 판단함으로써 복수개 종류의 사용자 입력값을 획득할 수 있다.According to an embodiment of the present invention, the first user input condition may be that the deformation state of the piezo element 1110 is changed from a normal state to a pressed state, that is, the user presses the piezo element 1110 firmly once. According to another embodiment, the second user input condition is that the deformation state of the piezo element 1110 is changed from a normal state to a pressed state and then back to a normal state, that is, the user presses the piezo element 1110 once and then releases the hand. it could be According to another embodiment, the third user input condition may be to repeat the first user input condition or the second user input condition a predetermined number of times. As such, the processor 1120 may differently generate a signal corresponding to a user input value by differently determining a user input value according to each user input condition. Accordingly, the present invention can acquire a plurality of types of user input values by determining the type of user input differently according to the user input condition.
추가적인 일 실시예에 따르면, 프로세서(1120)는 측정 전압이 기설정된 기준치를 초과할 경우 음향 경고를 출력하는 것으로 결정할 수 있다. 상술한 외부 압력(P)의 크기에 따라 피에조 소자(1110)의 눌림 상태에서 발생하는 양전압 또는 음전압의 크기가 커지므로, 측정 전압의 절대값이 클수록 외부 압력(P)이 크다고 판단할 수 있다. 피에조 소자(1110)에 가해지는 외부 압력(P)이 기준치를 넘어가는 경우 약액 주입 장치(1000)의 고장을 발생시킬 가능성이 높으므로, 프로세서(1120)는 측정 전압의 절대값이 기설정된 수치 이상인 경우 음향 경고를 출력할 수 있다.According to an additional embodiment, the processor 1120 may determine to output an audible warning when the measured voltage exceeds a predetermined reference value. Depending on the magnitude of the above-described external pressure P, the magnitude of the positive voltage or negative voltage generated in the pressed state of the piezo element 1110 increases, so it can be determined that the greater the absolute value of the measured voltage, the greater the external pressure P. there is. If the external pressure P applied to the piezo element 1110 exceeds the reference value, the chemical solution injection device 1000 is likely to fail, so the processor 1120 determines whether the absolute value of the measured voltage is greater than or equal to a preset value. In this case, an acoustic warning can be output.

도 10, 도 11을 참조하면, 사용자는 외부의 약액 주입기(미도시)를 이용하여 약액 주입 장치(10)의 레저버 유닛(200)에 약액을 주입한다.Referring to FIGS. 10 and 11 , a user injects a chemical solution into the reservoir unit 200 of the chemical solution injection device 10 using an external chemical solution injector (not shown).
사용자는 약액 주입기(미도시)에 주입될 약액을 넣고, 상기 약액 주입기를 레저버 유닛(200)의 입구단으로 삽입한다. 이때, 레저버 유닛(200)의 내부에 잔류된 공기는 프라이밍 될 수 있다.A user puts a liquid to be injected into a liquid medicine injector (not shown) and inserts the liquid medicine into the inlet end of the reservoir unit 200 . At this time, the air remaining inside the reservoir unit 200 may be primed.
상세히, 레저버 유닛(200)의 조립과정에서, 레저버 유닛(200)의 내부에는 공기가 잔류된다. 공기가 레저버 유닛(200)에 잔류된 상태에서 약액을 주입하면, 공기도 함께 사용자에게 주입될 위험이 있으므로, 공기를 제거하는 동작(프라이밍 동작)이 필요하다.In detail, during the assembly process of the reservoir unit 200, air remains inside the reservoir unit 200. If the chemical solution is injected while air remains in the reservoir unit 200, there is a risk that the air will also be injected into the user, so an operation to remove the air (priming operation) is required.
약액이 약액 주입기에서 레저버 유닛(200)으로 유입되기 시작하면, 레저버 유닛(200)의 내부에 유입되어 잔류된 기체를 니들부(N)로 밀어 내며 배출시킬 수 있다.When the liquid medicine starts to flow into the reservoir unit 200 from the liquid medicine injector, gas remaining inside the reservoir unit 200 may be pushed out through the needle part N and discharged.
니들부(N)을 통과한 기체는 니들 커버 조립체(700)로 이동하고, 니들 커버 조립체(700)의 필터 부재(도면 미도시)를 통과하여 외부로 배출될 수 있다. 이로 인하여 레저버 유닛(200)의 내부에 잔류된 기체는 신속하게 외부로 배출되어, 레저버 유닛(200)의 기체를 제거할 수 있다.The gas passing through the needle part N may move to the needle cover assembly 700 and pass through a filter member (not shown) of the needle cover assembly 700 to be discharged to the outside.

엔코더 유닛은 전기적으로 연결 신호 및/또는 전기적으로 해제 신호를 측정하여, 구동 유닛(400)의 구동과 관련된 데이터를 측정할 수 있다. 제어 모듈은 엔코더 유닛에서 측정된 데이터를 기초로 구동 유닛(400)의 회전각, 회전 속도를 산출하고, 이를 기초로 레저버 유닛(200)에 구비되는 플런저의 이동거리 및 약액의 토출량을 계산할 수 있다. The encoder unit may measure data related to driving of the driving unit 400 by electrically measuring a connection signal and/or an electrical release signal. The control module may calculate the rotation angle and rotation speed of the driving unit 400 based on the data measured by the encoder unit, and calculate the movement distance of the plunger provided in the reservoir unit 200 and the discharge amount of the chemical solution based on the calculation. there is.
