Aaron Ismach
Aaron Ismach (1920 in Brooklyn, New York - 2007) was an American scientist and inventor, who made a significative contribution to smallpox eradication by inventing the subcutaneous jet injector. Biography Born in Brooklyn, he earned a bachelor's degree in chemical engineering from the College of the City of New York in 1943, then a master's degree from the Polytechnic Institute of Brooklyn in 1953 and a MEE from the New York University in 1956. In the early 1960, Ismach developed a jet injector with an hydraulic pump operated by a foot pedal, known as the Ped-O-Jet. In 1964, Aaron Ismach invented an intradermal nozzle for the injector, which allowed delivery of the smallpox vaccines. He was awarded the Exceptional Civilian Service Award for his invention. During the 1967 World Health Organization's campaign of eradication of Smallpox, his device capable to vaccinate up to 1000 people an hour, was used for the mass vaccination Mass vaccination is a public policy effort to vac ...

Smallpox Eradication
Smallpox was an infectious disease caused by variola virus (often called smallpox virus) which belongs to the genus Orthopoxvirus. The last naturally occurring case was diagnosed in October 1977, and the World Health Organization (WHO) certified the global eradication of the disease in 1980, making it the only human disease to be eradicated. The initial symptoms of the disease included fever and vomiting. This was followed by formation of ulcers in the mouth and a skin rash. Over a number of days, the skin rash turned into the characteristic fluid-filled blisters with a dent in the center. The bumps then scabbed over and fell off, leaving scars. The disease was spread between people or via contaminated objects. Prevention was achieved mainly through the smallpox vaccine. Once the disease had developed, certain antiviral medication may have helped. The risk of death was about 30%, with higher rates among babies. Often, those who survived had extensive scarring of their sk ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subcutaneous Injection
Subcutaneous administration is the insertion of medications beneath the skin either by injection or infusion. A subcutaneous injection is administered as a bolus into the subcutis, the layer of skin directly below the dermis and epidermis, collectively referred to as the cutis. The instruments are usually a hypodermic needle and a syringe. Subcutaneous injections are highly effective in administering medications such as insulin, morphine, diacetylmorphine and goserelin. Subcutaneous administration may be abbreviated as SC, SQ, subcu, sub-Q, SubQ, or subcut. Subcut is the preferred abbreviation to reduce the risk of misunderstanding and potential errors. Subcutaneous tissue has few blood vessels and so drugs injected here are for slow, sustained rates of absorption, often with some amount of depot effect. Compared with other routes of administration, it is slower than intramuscular injections but still faster than intradermal injections. Subcutaneous infusion (as oppos ...

Jet Injector
A jet injector is a type of medical injecting syringe device used for a method of drug delivery known as jet injection, in which a narrow, high-pressure stream of liquid penetrates the outermost layer of the skin (stratum corneum) to deliver medication to targeted underlying tissues of the epidermis or dermis ("cutaneous" injection, also known as classical "intradermal" injection), fat ("subcutaneous" injection), or muscle ("intramuscular" injection). The jet stream is usually generated by the pressure of a piston in an enclosed liquid-filled chamber. The piston is usually pushed by the release of a compressed metal spring, although investigational devices may use piezoelectric effects and other novel technologies to pressurize the liquid in the chamber. The springs of currently-marketed and historical devices may be compressed by operator muscle power, hydraulic fluid, built-in battery-operated motors, compressed air or gas, and other means. Gas-powered and hydraulically powere ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mass Vaccination
Mass vaccination is a public policy effort to vaccinate a large number of people, possibly the entire population of the world or of a country or region, within a short period of time. This policy may be directed during a pandemic, when there is a localized outbreak or scare of a disease for which a vaccine exists, or when a new vaccine is invented. Under normal circumstances, vaccines are provided as part of an individual's medical care starting from birth and given as part of routine checkups. But there are times when there is a need to vaccinate the population at large and provide easy access to the service. When this occurs, temporary clinics may be established around communities that can efficiently handle the many people within at once. Challenges of a mass vaccination effort include vaccine supply, logistics, storage, finding vaccinators and other necessary staff, vaccine safety and public outreach.
