Health Care Issue

Air Pollution is killing over 500,000 people in China every year due to the extreme amount of pollutants found in the air. This is because China produces and consumes as much coal as almost the whole world combined. Coal inhalation can lead to things such as: bronchitis, emphysema, and asthma. In severe cases it can lead to things like black lung, lung cancer, and even death[3]. According to the EIA (The US Energy Information Administration) China’s coal consumption has risen by over 2.3 billion tons in the past 10 years.[4] The solution we have to this problem is an inhalant that will target specific toxins in the lungs and begin to break those toxins down, allowing macrophages to go in and begin the phagocytosis stage where they would finish breaking down these toxins. The device would most likely be administered at a hospital or outpatient clinic by a professional.

Customer Validation

The patients of our product would be the employees of Shenhua Group, China Coal Group, Shaanxi Group and Chemical Industry, and Shanxi Coking Coal Group. These are the people who are affected by the air pollution the most and would have the most to gain from our product.[21] This is because they are the ones who are breathing in all the air pollution in day after day without any protection or treatment.

The physicians that would administer our product would be the pulmonologists at hospitals that treat the people who have been affected by air pollution. These doctors gain more knowledge and a better product for treating people whose lungs have been damaged because of air pollution.

The providers of our product would be the nurses and doctors at the following hospitals, Guangdong General Hospital, General Hospital of Tianjin Medical University, Beijing Jishuitan Hospital and the Chinese General Hospital and Medical Center. These hospitals are the main ones for treating people with lung diseases caused by air pollution. [22]

The payers would be the insurance agents that deal with air pollution claims such as, China Life Insurance Co., Ping An of China, China Pacific Insurance, and the People’s Insurance Company of China Group. [21]

The purchasers of our product would be companies such as, Medtronic, Quest Diagnostics, Blue Cross Blue Shield, Bio-reference Laboratories, and LabCorp. They would benefit from purchasing our product because it could help end some diseases of the lungs caused by air pollution along with treating previous cases of lung diseases.


Comparison of existing medical solutions:


Our solution is designed to clean the lungs, repair and reverse the damage caused to the lungs by coal pollutants without affect the immune system of the patient. Our solution is unique because instead of addressing the symptoms of the problem, our solution addresses the root of the problem to make the patient healthier. This makes our product a long term solution. We aim to make our solution as affordable, accessible, and as easy to use as possible for those who suffer asthma and pneumoconiosis in China due to their working conditions.

US8037880B2, “Dry powder inhaler”, 2006-04-07, “A new dry powder inhaler is developed as a pulmonary medicine delivery device for dispersing precise tiny dosages (10 μg-50 mg) of pure carrier-free ultra-fine powdered medicament (<5 μm aerodynamics particle size) into a patient's lung. The powder is drawn from the blister cell and dispersed through an outlet tube assisted by two air streams. The first air stream goes through a the blister cell from its upstream side, to significantly fluidize the medicament in the dose to flow upward. The second one extracts the fluidized powder from downstream of the blister cell for further deagglomeration and dispersion of the medicament powder by shear force. The rotating multi-dose blister can hold up to 60 doses, which are pre-metered with pure ultra-fine powdered medicament. So that it has higher drug loading capability in small volumes, compared to most current dry powder inhalers, which usually use some excipient. The inhaler efficiently disperse the aerosolized medicament in the air stream to the deep interior of patient's lung. The fine particle fraction (<4.7 μm) is reported to reach as high as 80% using this inhaler.”[12]

Fundability Worksheet Scores

We chose a value of 2 because there are many inhalers out in the market right now and we are still in the design process of ours. Therefore, we are not sure how different this inhaler will be from the 3 main types of inhalers.

Customer Validation
We chose a value of 1 because our product is something that has not been made before and we will not have enough customer feedback by our presentation date.

IP Position

We chose a 1 because we could patent parts our technology; however, there are already many patents surrounding inhalers.
