Description

폐기능 평가가 가능한 수동식 공기호흡기{Manual-Ambu with assessment of pulmonary function}(Manual-Ambu with assessment of pulmonary function)

본 발명은 폐기능 평가가 가능한 수동식 공기호흡기에 관한 것으로, 더욱 상세하게는 응급환자 또는 중환자의 환기를 유지하도록 일회호흡량(Tidal colume)에 알맞은 공기 투여를 위하여 사용하는 수동식 인공호흡기(AMBU)에 있어서, 일회호흡량(압력포함), 인공호흡수(Respiratory rate), 호기말 가스 분압(End-ridal PCO₂& PO₂)을 측정하는 센서에 의해 계측한 데이터를 평가하여 환자의 병적상태에 따라 일회호흡량을 안정적으로 투여 및 유지함은 물론, 환자의 자발호흡 유무를 확인하여 디스플레이 함으로써, 환자의 상태에 대한 지속적인 모니터링이 용이한 폐기능 평가가 가능한 수동식 공기호흡기에 관한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hand-held respirator capable of evaluating pulmonary function, and more particularly, to a hand-held respirator (AMBU) used for air administration suitable for a tidal colum to maintain ventilation of an emergency patient or an intensive care unit , Respiratory rate (respiratory rate), and end-ridal PCO₂ & PO₂ (respiratory rate) were evaluated to determine the stable respiratory rate according to the patient's pathological condition The present invention relates to a hand-held air-operated respirator capable of evaluating the lung function to facilitate monitoring of the patient's condition by displaying whether or not the spontaneous respiration of the patient is confirmed and displayed.

일반적으로 수동식 공기호흡기(AMBU)는 응급환자 또는 중환자의 안정적인 환기를 호흡(환기)을 유지하도록 돕기 위하여 고농도의 산소 투여를 위하여 사용되는 것으로, 환자 스스로 호흡을 하기 어려울 때, 환자에게 직접적으로 산소를 공급해줌으로써, 심폐소생술과 같은 효과를 내기 위한 기구이다.In general, a hand-held air respirator (AMBU) is used to administer oxygen at a high concentration to help maintain a stable ventilation of an emergency or intensive care unit (ventilation). When the patient is unable to breathe on his own, It is a device for giving effect like cardiopulmonary resuscitation by supplying.

공기호흡기는 통상적으로 공기주머니를 압박하여 분당 12회 정도로 공기를 투여하되, 일회호흡량을 6 내지 7㎖/㎏ 또는 500 내지 600㎖를 투여하도록 미국 심장협회에서 권장하며, 환자의 상태에 따라 투여량을 조절하도록 이루어진다.The air respirator is normally recommended to be administered by the American Heart Association to administer air at a rate of about 12 times per minute by compressing the bladder, with a single dose of 6 to 7 ml / kg or 500 to 600 ml, .

이에 대한민국 등록실용신안 제0329009호에는 소방관 휴대용 산소 인공호흡기에 대하여 기술하고 있다.Accordingly, the Korean Utility Model No. 0329009 describes a portable oxygen oxygenator for firefighters.

그러나, 상기와 같은 인공호흡기는 전문적인 응급처치 기술을 가진 소방관이나 또는 의료종사자에 한해서만 사용될 수 있는 것으로, 일반 조작자가 사용하기에는 어려운 문제점이 있었다.However, the above-described ventilator can be used only for a firefighter or a medical practitioner who has a professional first aid technique, and it is difficult for a general operator to use.

특히, 심근경색이나 뇌출혈과 같은 질병은 신속한 응급처치가 이루어져야 하는데, 종래의 인공호흡기는 환기량을 측정할 수 있는 방법이 보급되어 있지 않기 때문에, 일반인이 이러한 응급상황에서 인공호흡기를 이용하여 심폐소생술시 과도한 흡기 압력으로 인한 과호흡이 발생하여 흉부압력 증가나 폐손상을 야기하거나, 흡기량 부족으로 인한 저호흡이 발생하여 저산소혈증을 유발하여 오히려 상태를 악화시키는 경우가 발생하였다.Particularly, diseases such as myocardial infarction and cerebral hemorrhage should be promptly treated first. Since conventional ventilators do not have a method of measuring the amount of ventilation, a general public can use the ventilator to perform CPR Excessive inspiratory pressure caused hyperventilation resulting in increased pressure in the chest or lung injury, or hypoventilation due to lack of intake, resulting in hypoxemia and worsening the condition.

즉, 일회호흡량과 인공호흡수를 환자의 상태에 따라 조절하여야 하는데, 종래의 인공호흡기는 소방관이나 전문의 등 조작자의 경험에만 의존할 수 밖에 없기 때문에, 환자의 상태가 급변하는 경우 대처능력이 현저히 떨어지게 되어 응급처치가 제대로 시행되지 않는 문제점이 발생되었다.
That is, the one-time respiratory volume and the artificial respiratory rate should be adjusted according to the patient's condition. Since the conventional artificial respirator is only dependent on the experience of the firefighter or the professional operator, And the first aid was not performed properly.

본 발명은 상술한 문제점을 해결하기 위한 것으로, 그 기술적 요지는 응급환자 또는 중환자의 환기를 유지하도록 일회호흡량(Tidal colume)에 알맞은 공기 투여를 위하여 사용하는 수동식 인공호흡기(AMBU)에 있어서, 일회호흡량(압력포함), 인공호흡수(Respiratory rate), 호기말 가스 분압(End-ridal PCO₂& PO₂)을 측정하는 센서에 의해 계측한 데이터를 평가하여 환자의 병적상태에 따라 일회호흡량을 안정적으로 투여 및 유지함은 물론, 환자의 자발호흡 유무를 확인하여 디스플레이 함으로써, 환자의 상태에 대한 지속적인 모니터링이 용이한 폐기능 평가가 가능한 수동식 공기호흡기를 제공하는 것에 그 목적이 있다.Disclosure of Invention Technical Problem [8] The present invention has been made to solve the above problems, and it is a technical object of the present invention to provide a manual ventilator (AMBU) which is used for air administration suitable for a tidal colum to maintain ventilation of an emergency patient or an intensive care unit, The data measured by the sensor measuring pressure (including pressure), respiratory rate (respiratory rate), and end-tidal gas partial pressure (end-ridal PCO₂ & PO₂) were evaluated and the one-time respiratory rate was stably administered and maintained according to the patient's pathological condition And an object of the present invention is to provide a hand-held air-operated respirator capable of evaluating the lung function easily by continuously monitoring the patient's condition by displaying and confirming the spontaneous breathing state of the patient.
