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?

Two Hospital Labs Use PAS Portable HEPA Systems

Recently two major hospitals purchased one the model HPS 500 portable HEPA systems by Pure Air Systems. They are Bellevue Hospital in New York City and Rhode Island Hospital in Providence Rhode Island. The HEPA units were purchased for the medical laboratory for each Hospital.

Bellevue is the oldest public Hospital in the country, founded in 1736, and one of the most well known in the U. S. Rhode Island Hospital is one of a group of medical facilities in Rhode Island which service almost the entire state. Each of these Hospitals enjoys a reputation for providing state-of-the-art medical care using the latest advancements in medical technology.

A clinical laboratory or medical laboratory is a laboratory where tests are done on clinical specimens in order to get information about the health of a patient as pertaining to diagnosis, treatment and prevention of disease. These facilities maintain a semi-clean room environment so there is no cross contamination of specimen samples.

The Pure Air System portable HEPA units use a certified, commercial grade HEPA filter that removes 99.99% of airborne particles 0.3 microns or larger and removes a high percentage of particles down to 0.12 microns. These units are fabricated from powder coated steel and use a four speed blower/motor assembly to allow for variations on air flow to meet the specific needs of the customer. These units also have a combination prefilter/carbon medial filter to remove large particles, reduce odors and help maintain a longer life for the HEPA filter. With air flows up to 500 CFM the portable units can provide significant air exchange rates even in large areas.

The HPS series of portable HEPA units are approximately 13″ square  and 21″ long and weight less than 30 lbs. They are rugged and designed for continuous use operations. These units represent some of the most powerful,portable, true HEPA filtration systems on the market today.

Pure Air Systems has been manufacturing high end, commercial grade, HEPA filtration systems since 1985 and has their systems in commercial, institutional, industrial and residential applications around the world. So for Bellevue and Rhode Island Hospitals, the choice was easy. Buy the best portable HEPA systems on the market for their laboratories.

Clean Room Environment For Medical Device Manufacturers

With over 6 billion people on the planet and at least 3 billion of them using some form of health care system, the need for all types of medical devices continues to grow. From medical devices products as simple as syringes to complicated and life saving Stents, the need for these products continues to explode and the manufacturing techniques are becoming much more sophisticated.

One of the main challenges facing most hospitals, clinics and out patient facilities that use these numerous medical devices is the constant threat of infection especially post-operative infections. The advent of the newer, more drug resistant strains of bacteria, or MRSA, have made the medical community more aware of the need for reducing any possibility for infection from outside sources.

To ensure these medical devices and products are bacteria free they are manufactured in clean room environments and then sterilized prior to being encased in an air tight enclosure or special wrap.

The technicians that assemble these devices are often gowned and wear latex gloves and masks. This ensure no contamination from the technicians to the devices during the assembly process.

To ensure the entire environment where the materials, parts and final assembly take place is totally free of microscopic airborne contaminants, high efficiency particulate air filters ( HEPA) are used. The entire assembly areas are constantly washed with the HEPA filtered air to ensure a clean room type of environment and to reduce the possibility of shipping a medical device that could be contaminated and thus create a problem for the patient on which the product is used.

HEPA filters by design have a minimum efficiency of removing 99.97% of all particles 0.3 microns or larger. Many of  the HEPA systems today use even more efficient HEPA media that can remove up to 99.9995% of all particles 0.12 microns and larger.

Pure Air Systems has been producing HEPA based air filtration systems since 1985 and has hundreds of units in operation in the medical market including;  hospitals, clincs, surgery rooms, pharmaceutical manufacturing, post-operative recovery rooms, medical device manufacturers and doctor’s offices.

Pure Air Systems offers a line of fan powered, HEPA based (99.99% at 0.3 microns) systems that range from 300 CFM to 2000 CFM using variable speed drive motors for finite control of air flow. These units can be used as a portable system or attached to existing HVAC units and ductwork. The flexibility and high performance capabilities of the PAS HEPA product  line make it one of the most effective line of HEPA filtration systems on the market today.
