Air Measuring Sensor, Design, Manufacture and Test to Measure the Amount of Air in the Invazive Mechanical Ventilator

Abstract

The corana virus that started in the city of Wuan in China has turned into a pandemic that affects the whole world. Since this disease affects the functioning of the lungs, the need for mechanical ventilators has increased rapidly in the world. The fact that all countries in the world are needed at the same time has caused an explosion in demand. The high demand and the low supply caused the need for spare parts and devices to increase, which revealed the need to solve the problem with domestic resources. During the pandemic period, the biggest problem was to be able to supply the venturi tube rather than producing it cheaper. In order to measure the amount of air in the invasive mechanical ventilator, a venturi tube with a suitable diameter was designed and a venturi meter was produced.

İnvazive Mekanik Ventilatörde Hava Miktarını Ölçmek için HavaÖlçme Sensörünün Tasarımı, İmalatı ve Testi

Abstract

Çinin Wuan kentinde başlayan korana virüsün yol açtığı Covid-19 Hastalığı bütün dünyayı etkileyen bir pandemiye dönüştü. Bu hastalık akciğerlerin çalışmasını etkilediği için mekanik ventilatör ihtiyacı dünyada hızlı bir şekilde artmıştır. Bütün dünya ülkelerinin aynı anda cihaza ihtiyaç duyulmaları talebin patlamasına neden olmuştur. Talebin yüksek olup arzın az olması yedek parça ve cihaz ihtiyacının artmasına neden olmuş bu da yerli imkânlarla konunun çözümünün gerekliğini ortaya koymuştur. Pandemi süresinde ventüri tüpünü daha ucuza üretmekten ziyade tedarik edebilmek en büyük problem olarak ortaya çıkmıştır. İnvazive mekanik ventilatörde hava miktarının ölçmek için uygun çapta venturi tüp tasarlanarak üretimi gerçekleştirilmiştir.
