Description

휴대용 천식 의료기기{potable asthma medical instrument}Portable asthma medical instrument

본 발명은 약물의 분사시간과 정지시간을 정확히 알고 편리하게 약물을 복용하도록 한 휴대용 천식 의료기기에 관한 것이다. The present invention relates to a portable asthma medical device to accurately know the injection time and stop time of the drug to take the drug conveniently.

종래 천식 의료기기인 네블라이저는 사람이 직접 가압해서 분사하거나 아니면 펌프를 이용해서 일정시간 분사하고 정지해서 약물을 복용하는 형태이다. Nebulizer, a conventional asthma medical device, is a form in which a person directly pressurizes or sprays or injects a drug by spraying and stopping for a predetermined time using a pump.

그러나, 천식 환자는 천식 정도에 따라 또는 연령에 따라 그 약물의 복용 시간과 정지 시간이 다 다르기 때문에, 일정량 분사 및 정지하는 것만으로는 약물의 오용 남용과 빠른 천식 발작 완화 등을 기대하기 어렵다. However, since asthma patients have different doses and stoppage times of the drug depending on the degree of asthma or age, it is difficult to expect the drug to be abused and stopped as soon as possible by stopping and dispensing a certain amount.

또한, 특허문헌과 같은 네블라이저 등은 펌프가 외부에 있어 휴대가 곤란해서 갑작스런 천식 발작이 왔을 때 사용할 수 없다. In addition, a nebulizer such as the patent document cannot be used when the pump is external and is difficult to carry and a sudden asthma attack occurs.

이하, 전술한 구성을 갖는 본 실시예의 작용을 설명한다.The operation of this embodiment having the above-described configuration will be described below.

먼저, 약물을 공간부(11c)에 넣고, 연결체(15)를 약물 수용체(11)의 상부에 놓은 후에 연결체(15)를 회전시켜서 체결돌기(11d)가 연결체(15)의 체결홈(미도시)에 끼워지도록 한다. First, the drug is placed in the space portion 11c, the connecting body 15 is placed on the upper part of the drug receptor 11, and then the connecting body 15 is rotated so that the fastening protrusion 11d is a fastening groove of the connecting body 15. (Not shown).

사용자가 입력 버튼부(25) 중 원하는 버튼을 누르면, 펌프(20)가 작동하여 유입구(21)로 동시에 유입된다. 유입된 외기는 펌프(20)의 토출구(23)를 통해 토출된 후 통기관(11b)으로 이송된 후, 유도체(15d)에 부딪혀서 공간부(11c)에 있는 약물에 공급되어 공간부(11c)에 있는 약물은 미립자 형태로 되어, 배출구(15b)로 배출되어 노즐부(13)의 수평관부(13b)로 이송된다. 이어서, 미립자 형태로 된 약물은 커넥터(50)를 통해 실리콘 마스크(30)로 분사 공급된다.When the user presses a desired button of the input button portion 25, the pump 20 is operated to flow into the inlet 21 at the same time. The introduced outside air is discharged through the discharge port 23 of the pump 20 and then transferred to the vent pipe 11b, and then supplied to the drug in the space portion 11c by hitting the derivative 15d to the space portion 11c. The drug in the form of particulates is discharged to the discharge port 15b and transferred to the horizontal tube portion 13b of the nozzle portion 13. Subsequently, the drug in particulate form is sprayed and supplied to the silicon mask 30 through the connector 50.

이러한 약물의 분사 시간과 정지 시간은 천식 환자의 연령이나 천식 정도에 따른 버튼을 선택해서 누르면, PCB(19)가 펌프(20)의 구동을 제어한다. The injection time and stop time of the drug is selected by pressing a button according to the age or degree of asthma of the asthma patient, the PCB 19 controls the driving of the pump 20.
