Portable Air Purification System Used in Medical Environments

Abstract

The protection of air quality in public areas in the community is important for health and is a current problem. This problem often manifests itself with epidemic diseases or deaths in large or small healthcare institutions, along with many common areas where ventilation is insufficient. The steps taken so far are insufficient to prevent this problem, In the study, a small and portable air purification system was designed using particulate filters and UV lamps, providing medical-grade air quality. This system has been designed in accordance with EN ISO 14644-1 cleanroom standards using UV-C technology. This device can be used in health institutions such as public transportation vehicles, intensive care waiting rooms, microbiology, and biochemistry laboratories.

Tıbbi Ortamlarda Kullanılan Portatif Hava Temizleme Sistemi

Abstract

Toplum içerisinde ortak kullanıma açık alanlarda hava kalitesinin korunması sağlık açısından önemlidir ve güncel bir problemdir. Bu problem, havalandırmanın yetersiz olduğu birçok ortak kullanım alanı ile birlikte büyük veya küçük sağlık hizmeti veren kuruluşlarda kendini sıklıkla salgın hastalıklarla ya da yaşanan ölümler ile göstermektedir. Bu problemin önüne geçilebilmesi için bu zamana kadar atılan adımlar yetersiz kalabilmektedir. Çalışma kapsamında, partikül tutucu filtreler, UV lambalar kullanılarak, küçük ve taşınabilir, medikal seviyede hava kalitesi sağlayan bir hava temizleme sistemin tasarlanmıştır. Bu sistem EN ISO 14644-1 temiz oda standartlarına uygun olacak şekilde UV-C teknolojisinden yararlanılarak tasarlanmıştır. Bu cihaz, sağlık kuruluşlarındaki toplu taşıma araçları, bekleme ve yoğun bakım odaları, mikrobiyoloji ve biyokimya laboratuvarları gibi yerlerde kullanılabilir niteliktedir.
