Medical mini-environment device

Abstract

A ventilation apparatus for forming a sterile medical area mainly includes an operation module for ventilating the air. The apparatus for ensuring the air cleanliness includes a filtering unit for filtering dusts and particles in the air and a sterilizing unit for eliminating micro organisms. The clean and sterilized air is sent into the medical area via an air outlet to form a quasi-laminar air flow pattern. By application of the ventilation apparatus, the cleanliness of the medical area can be ensured.

AI Technical Summary

Benefits of technology

[0014]Accordingly, it is an object of the present invention to provide a ventilation apparatus for forming a sterile medical environment, in which a quasi-laminar downward air-flow pattern is introduced to ensure the cleanliness in a application region, in particular a sterile medical district. The ventilation apparatus of the present invention mainly includes a driving unit for circulating the air flow, a filtering unit for filtering dusts and pollutants in the air, a sterilizing unit for eliminating germs in the air so as to assure the air quality and cleanliness. By circulating clean air flow to a certain medical district, a clean and sterile medical environment can then be formed.

Problems solved by technology

Definitely, medical staffs and people in those medical facilities are jeopardous.

However, by replacing with a fan-filter unit (FFU) to overcome the foregoing problems, a huge expense and possible a space reconsideration are definitely inevitable.

These disadvantages include:1. generating a turbulent flow with a low-cleanliness which cannot effectively removes the pollutants;2. lacking control in direction of the pollutants flow; and3. unable to stabilize the air quality and cleanliness in a certain district.

Such a design is applicable for industry, e.g. general industrial, food industrial and dangerous industrial, but is not suitable for medical application.

This is because such apparatus fails to provide the patient with a uniform distribution of clean air, and the patient exposed to such atmosphere may feel uncomfortable.
