Introduction:
Asthma is increasing in all cities of all industrial nations. Asthma affects kids to all ages. The sickness & deaths are increasing all over. Inhalers are the preferred devices for lung drug delivery. Unfortunately, patients are unhappy with inhalers. There are 2 types of inhalers -- MDI (metered dose inhaler) with a propellant & DPI (dry powder inhaler) with no propellants. Propellants are polluting, may be ozone depleting. DPI sprays the powder as spray. Both are not deep inhaling.

Idea: Why not a deep, easy inhaling nonpolluting low cost devices for all ages?

We need to change the design for easy inhalation.

The Device:
It has a body with a small narrow mouthpiece holding a capsule. It has inside a needle fitted on a spring assisted plunger. The body is streamlined -- wide back, narrow front for maximal air velocity to spray the powder.

Mode of Use:
Load the drug capsule with the needed drug in mouthpiece. Push the plunger. This needle creates a hole in the capsule, 4mm in back 3mm in the front of the capsule. Keep mouthpiece in mouth & inhale. The air from the back creates a high velocity flow in the back of the capsule & sprays from the front of capsule.

The inhalation is deep & long. The mouthpiece is 8-10 mm wide. The MDI inhalers have more than 15mm opening & produce slow shallow breathing -- hence failure is reduced in ours.

The other DPIs have no axial high velocity air flow creation -- better powder spray in ours.

Advantages:
1. Deep slow inhalation for all ages.
2. Anyone can use it- no dose counting, coordination problems
3. Eco safe, low cost.
4. It glows in the dark for easy visualization at night.

Conclusion:
Affordable easy inhaler for asthmatics. We have also done few lung scans. For naming we call it Maxhaler- maximum inhalation.
