About this deal

Examples of normally employed “excipients,” include pharmaceutical grades of dextrose, sucrose, lactose, trehalose, mannitol, sorbitol, inositol, dextran, starch, cellulose, sodium or calcium phosphates, calcium sulfate, citric acid, tartaric acid, glycine, high molecular weight polyethylene glycols (PEG), and combinations thereof. a sonic nozzle 4 Fitted generally midway along the central aperture of the main body 1 is a sonic nozzle 4 . comprises an elongate tubular converging-diverging nozzle having a rupturable membrane initially closing the passage through the nozzle and arranged substantially adjacent to the upstream end of the nozzle. The International Standards Organization recommended abandoning the use of the name "jet injector", which is associated with a risk of cross-contamination and rather refer to newer devices as "needle-free injectors". Oscar Banker, an engineer, patented his invention of a portable multi-use nozzle jet injector that utilizes CO 2 as its energy source.

a gas/particle exit nozzle bounding said gas flow path for the acceleration therealong of the drawn in particles entrained in the gas. the second convergence 9 has a much reduced flow cross-section relative to the flow cross-section of the chamber 8 . While seeing a dermatologist for a filler may cost more than a needle-free filler, it’s well worth the investment.the middle image shows the distribution of particles across a diametral slice of the target and the left hand image shows an enlarged view of particle penetration at the center of the slice, from which a maximum penetration of 250 ⁇ m can be measured.

However, the gas issuing from the device is actually a mixture of helium and air, due to the air that is drawn in along with the particles via the particle inlet passage 10. describes a needleless syringe that delivers pharmaceutical particles entrained in a supersonic gas flow.Population risk (Veterans and children) for another deadly virus, previously known as "non A- non B" or Chronic Hepatitis C "CHC or HCV" ". This embodiment can therefore be utilized to provide a more even spread of particles and less “coring” of the gas stream. This is the earliest documented jet injector to administer water or medicine under enough pressure to penetrate the skin without the use of a needle. the passage through the nozzle has an upstream convergent portion, leading through a throat to a downstream, divergent portion. As used herein, the terms “therapeutic agent” and/or “particles of a therapeutic agent” intend any compound or composition of matter which, when administered to an organism (human or animal) induces a desired pharmacologic, immunogenic, and/or physiologic effect by local and/or systemic action.
