The Problem To Be Solved:

With outbreaks of e. coli, salmonella and other bacterial and parasitic pathogens over the years, there has been much public concern about contamination and the spread of infectious diseases.

While telephones including cellphones, are a seemingly harmless and commonly used tool, according to studies done by the University of Arizona, telephones are one of the biggest collectors and spreaders of germs.

Yet there are a wide variety of sensitive environments where the telephone/cellphone is a vital tool on the job, while simultaneously posing serious hazards to users and/or patients.

Handsfree Sani-PhoneTM

Uses include sterile rooms
such as labs and clean rooms

1) Sani-PhoneTM Booth Unit:
Public and Commercial version

Existing phone booths are filthy and contaminated with germs. When using public phones, people worry about the spread of infectious diseases through germs, bacteria, or viruses on the dial pad, handset, particularly on the mouth and ear pieces. These days, the unsanitary nature of public phones are a major hindrance to their use by a majority of the public. Yet due to poor cellphone reception in many areas, public phones are still needed in many instances, especially in emergencies.

The Handsfree Sani-Phone BoothTM is a premium high end phone booth for people who worry about contamination and who are willing to pay a premium price to use a completely handsfree, sanitary phone booth. It features a distinctive design with a futuristic tubular shaped, acrylic, see-through, soundproof booth which is well lighted.

These specialty phone booths will be located within secure public areas like airports, shopping malls, hotels, hospitals, restaurants, office buildings, etc. in addition to well lighted, protected areas such as 24/7 Seven Eleven stores in middle, working class neighborhoods as well as wealthier neighborhoods where they can be easily maintained, and where they're less likely to be vandalized.

Utilizing special software that is voice activated, and that works with the special hardware, upon approaching the phone booth, if somebody is already inside using the phone, the sensors activate a voice command, for example, "The Sani-Phone booth is in use. Please wait a minute, thank you." Once the previous person leaves, the sliding door automatically opens, and when the person enters the booth, closes behind him/her. The system then asks whether the call is local or long distance, what number they would like to call, verifies the number, payment method, etc.

These phone booths are also programmed for use in emergencies, responding to words like help, 911, police, fire, emergency and automatically dialing 911. They have a global tracking system which pinpoints their location for instant deployment of emergency help.

2) Sani-PhoneTM Wall Unit:
Industrial version for medical/industrial

Uses include hazardous
work areas such as

In the hospital operating room (OR), it is fairly common for physicians and staff members to make calls to outside doctors or other staff using a fixed phone in the room, or to use their personal cellphones. However, studies have shown that both types of phones have been found to carry bacteria and contaminate the physicians hands, which can contribute to cross contamination causing infections and complications for the patients. Additionally, cellphone use in the OR can cause electromagnetic interference to critical medical devices. The Sani-PhoneTM would eliminate this aspect of contamination in the OR, as well as equipment interference.

Other uses include clean rooms and other sterile areas such as laboratories, etc. and hazardous work areas such as nuclear power plants, germ contamination centers, etc. that require wearing bulky contamination suits, which makes it difficult to make phone calls.

For these uses, a special wall unit with a partial partition would be available. It would be designed with the idea of preventing feedback and providing clear sound. With this version, the Private Calling, Semi-Private Calling, or Conference options would be used depending on the situation. Although if privacy is not an issue, the regular mode can be used.

3) Sani-PhoneTM Desktop Unit:
Residential version for seniors and handicapped people

With an aging population and the likelihood of disability increasing with age, the growth in the number of people with disabilities can be expected to accelerate in the coming decades.

A residential version would include a desktop version that can be utilized in hospital patient rooms, nursing home patient rooms, long term care facilities, as well as home use for individuals with limited mobility. This handsfree model is compact, efficient, and provides easy communication.

Target market:

Due to the initial higher introductory manufacturing costs, the Handsfree Sani-PhoneTM is a specialty niche market product that will be targeted to the specific markets identified above. However as the technology gets more advanced, the Handsfree Sani-PhoneTM will be become available at a competitive price range that the consumer market can afford.

Note: Product has two issued patents with an additional patent pending. A prototype can be developed for a relatively small cost.
