Modification of the Ventilation fan mask with a Mechanical Ventilator in an accident patient, Hamilton G5 model

Abstract

Mechanical Ventilators are very important in accident patients because they can save lives and support breathing in patients who have been injured in an emergency accident and cannot breathe on their own or have acute respiratory failure. The Hamilton G5 ventilator is a high-end device used in hospitals. However, the unit found a problem with the fan cover on the back of the machine breaking after continuous use. As a result, the air filter could not be installed firmly because of the breakage. Dust may enter the ventilator system, damage the main circuit board, especially affecting the patient's respiratory system, and risk of pneumonia caused by infection after wearing the ventilator for a long time. Although there was an initial repair with epoxy glue, because the mask had to be removed frequently for cleaning, and the glue repair could not withstand the pressure from prying it open from the machine, it was damaged again. To reduce costs and waiting for spare parts from abroad, the unit modified it by using spare parts from old computers with accessories such as iron grills, nuts, and nut washers, etc. to create a replacement mask. From the trial, it was found that it works well, is strong, easy to remove and remove, and does not break again even after continuous use for more than 5 years. This modification is therefore one way to increase the efficiency of medical equipment maintenance in a time of limited resources. It also effectively reduces the budget burden of the unit.
