Better Safe Than Sorry

A simple phrase that has been used millions of times for over a hundred years. Often told to children by their parents, the “better safe than sorry” statement allowed you to have someone use a safer material or wear some protective cloths or even buy travel insurance just to be on the safe side. Of course for those who throw “caution to the wind” this phrase is merely another reason to have to follow some stupid rule.

The new APPAIS unit, from Pure Air Systems, is a new design of the portable HEPA unit designed to be used in conjunction with injections given by Pharmacists, Nurses, Doctors and Clinicians in any environment that is not antiseptically clean. ( which are most environments). This unit has the ability to maintain a clean pocket of air that surrounds the area of the arm or body that will be injected.

Injections are relatively simple, but they process is not really done under any particular guidelines. With more injections being done in Pharmacies, Walmarts, Retail Medi-Centers, etc, etc, you have individuals who are having their skin punctured in environments that are far from being clean and that are contaminated by people, products and an assortment of airborne pathogens that would make you shutter if you actually knew what was in the air. And this is where you will get punctured or injected.

The APPAIS unit uses commercial grade HEPA filters that are 99.99% effective on particles 0.3 microns and larger and approach 98% efficiency on particles smaller than 0.3 microns. The system has been recognized by the FDA to provide an Iso 6 environment ( less than .05 % ) particulate at 0.3 microns or larger 40″ from the face of the unit. This means the injection site is in an environment that is very close to that of a surgery room. Now,  wouldn’t you want to have your injection with the APPAIS unit rather than next to a rack of candy, books or other materials?

Final Approval

In August the FDA gave final approval to allow us to market the new APPAIS™ HEPA filtration system to the medical market. The APPAIS  unit is a modified version of the HPS Portable HEPA unit that is designed to eliminate the need for any tools to change any of the three filters that are included with each unit.

The APPAIS unit is designed to provide a Class 100 environment 20″ from the discharge of the HEPA unit. This washed area will be used to administer injections. The syringe will be opened and  pulled  to clear in this sterile area and the patients arm will also be set approximately 10″ to 12″ from the HEPA discharge face. This will ensure that any puncture area will be in a very clean environment thus minimizing the possibility for any airborne particulates or pathogens to enter the patients blood stream thus reducing the possibility for infection.

The APPAIS unit has two slots on the top ends that allow for the placement of either the Polyester Ring Panel prefilter, located on the  air inlet end of the unit, keeps the blower/motor and electrical harness clean and protects the HEPA filter from getting loaded too quickly with large dust and dirt particles. The other slot holds the Splash filter that keeps any human fluids from penetrating the HEPA filter which is located just  behind the Splash filter.

The slots have snap in covers that keep the two filters in place. To eliminate any confusion we have different size slots so the prefilter and Splash filter can only go into their respective openings. The snap in covers are also mated to the openings so again no confusion on location.

In order to maintain a tight seal for the HEPA  gasket we included a knife edge seat section against which the HEPA filter sits in the unit. Compressing the HEPA  against the seal used to require a complicated device that required four screws and a tool to remove and replace the HEPA. The new APPAIS  unit has a simple  compression bar that is placed between the HEPA aluminum face and the first internal mounting frame. By simply twisting the flat compression bar the HEPA body moves back and compresses the gasket onto the knife edge seal creating a very tight seal. Again, no tools are required.

The APPAIS unit is mounted to a five star wheel rolling base stand that is much like a business chair unit with a pneumatic actuator that allows for height adjustment to accommodate for patient sizes and proper arm location. The base also supports the syringe holder so the Doctor or Pharmacists will always have the proper materials right at the APPAIS unit.

Our  initial market will be Pharmacies as they are now doing more injections than Doctors offices especially with Flu and Shingle shots. We hope to have some of our first units in the market by the first quarter of 2015 if not sooner. Look for the all white APPAIS  unit at your favorite Pharmacy the next time you go for your annual flu shot.
