Asthma is one of the most common diseases in this world. According to <Global Asthma Report 2014> from AsthmaUK, there are over 300 million asthma patient in this world.
So far the most efficient methods to cure or improve asthma are Aerobic Exercise and Medical Treatment. But these two methods are all inevitably have their own drawbacks.
Drawbacks of Medical Treatment:
—SIDE EFFECTS : average height of the children who take Budesonide for 400 uq a day is 1.2 cm shorter than average level of normal children.
— EXPENSES: Using Salbutamol Sulfate and Budesonide everyday as well as taking Nebulization therapy for a certain period can causes high expenses.
— INCONVENIENCE: Nearly all the medical treatments for asthma should be conducted everyday, otherwise, the treatments outcome would not be as effective as expected.
Drawbacks of Aerobic Exercise:
— Highly risky in triggering asthma: air can be moistened and warmed and the allergen among it can be cleaned out by nasal cavity when breath by nose. But when doing aerobic exercise, dry, cold, uncleaned air can be breathed in when patient use their mouths to breath in order to take in more oxygen, which can easily stimulate the respiratory tract and causes respiratory spasm, which is asthma.
So we can see there is a huge contradiction. The Aerobic Exercise as the most healthy method to cure the asthma, can also be the most dangerous event for asthma patient. This project will focus on how to help asthma patient enjoy aerobic exercise at the same time protect them from asthmatic attack.
The idea is the to make a mask that can not only create a warm, moisture air for patient to breath but also filter the allergen when doing aerobic exercise. After some research works, Ultrasonic atomization and PTC heater were applied on this project.
In the test part, we connect PTC Heater, Ultrasonic Atomization to two batteries (750 mAh, 3.7v for each) with mother board and transformer to make them fully functional. The result is, with 1500 mAh batteries, the whole system worked for 130 mins, which is definitely enough for a adult to use when doing aerobic exercise. As for kids, based on our research, most of the kid won't do exercise more tham 40mins, which means only one battery (750 mAh, 65 mins) can meet the demands of children.
The volums of water tank is presicely calculated based on the water consumption rate, 25ml for adult and 16ml for child which can approximately cover the battery life. In addition, the water tank of childrens mask is replaceable, which means their parents can always have a back up water tank just in case.
Filling in the water is as simple as showed above. A small open can be found on the back of adult version mask after the silicon mask was removed. The water tank of child version mask can be easily opened after being removed from main body.
By using one-way pipe to create an clean dry air circulation system. Separating the air that being breathed in and out prevents the fogging in the inside of mask, which can create an nice, comfortable, dry and clean breathing environment.
