  1. 1. Needle Free Injection Technology Advantages of Needle Free Injection Systems
  2. 2. 2 Needle Free Injection Technology Audience Medical & Health Boards Humanitarian Foundations and Organizations I represent manufacturers and developers of needle free injection technology.
  3. 3. 3 Needle Free Injection Technology Companies
  4. 4. 4 Needle Free Injections Introduction I’m here to speak to you about needles, boosters, vaccinations, flu shots  We’ve all had to get them  Most of us don’t like them  Some people cry, get scared or even faint Introduction Current Ideal Proposed Conclusion
  5. 5. 5 Needle Free Injections Introduction Goal of this presentation: Present alternative methods of medication delivery. Discuss the features and advantages of needle free injection systems over traditional hypodermic needles in the administration of serums, vaccinations and other medicines. Introduction Current Ideal Proposed Conclusion
  6. 6. 6 Needle Free Injections Introduction The Problem  Vaccinations & inoculations The Current Method  Hypodermic needles The Ideal Solution  Efficient, cost effective The Proposed Method  Needle free injectors Introduction Current Ideal Proposed Conclusion
  7. 7. 7 Needle Free Injections Contents 1. Current Method  Hypodermic Needles  Development  Description  Advantages  Problems 2. Ideal Solution 3. Proposed Solution  Alternative Delivery Systems  Needle Free Injectors  Development  Description  Advantages  Problems 4. Conclusion Introduction Current Ideal Proposed Conclusion
  8. 8. 8 Needle Free Injections 1. Current The Current Method Liquid serums Needle and syringe Sterile equipment Well trained staff Cultural challenges to needles Introduction Current Ideal Proposed Conclusion
  9. 9. 9 Needle Free Injections Development Hypodermic Needle - a brief history 1844 Irish physician Francis Rynd invented the hollow needle. 1853 French physician Charles Pravaz & Edinburgh physician Alexander Wood independently developed the first practical metal syringe adding a hollow needle to the end of a glass syringe. Introduction Current Ideal Proposed Conclusion
  10. 10. 10 Needle Free Injections Development An Early Hypodermic Needle Glass tube & plunger Hollow steel needle Introduction Current Ideal Proposed Conclusion
  11. 11. 11 Needle Free Injections Description The Modern Hypodermic Needle Plastic Syringe & Plunger Stainless Steel Needle in Plastic Tip Introduction Current Ideal Proposed Conclusion
  12. 12. 12 Needle Free Injections Advantages Hypodermic Needles are Inexpensive – needle & syringe Versatile – wide variety of medicines Familiar – well known technology Scaleable – various syringe sizes accommodate different doses Introduction Current Ideal Proposed Conclusion ($22.95 for 100 1cc size) ($41.75 for 100 5cc size) ($42.75 for 100 10cc size)
  13. 13. 13 Needle Free Injections Problems Hypodermic Needle problems Needlephobia Substantial training required Difficult to insert needle to correct depth Necessary to aspirate the needle to ensure not hitting a blood vessel Keeping the needle steady Introduction Current Ideal Proposed Conclusion
  14. 14. 14 Needle Free Injections Problems Hypodermic Needle problems Danger of being stuck by used needle Disposal of needle tips called “sharps” Medication waste & ineffective treatment if delivered to improper depth Possible re-use of needles Introduction Current Ideal Proposed Conclusion
  15. 15. 15 Needle Free Injections 2. Ideal Solution Ideal Solution Inexpensive Low-level of Training Powdered medication (refrigeration, transport) Non invasive (nothing penetrates the skin except the medicine) Dispel Needlephobia Disposable (no reuse or accidental stick injuries) Introduction Current Ideal Proposed Conclusion
  16. 16. 16 Needle Free Injections 3. Proposed Solution The Proposed Method Needle Free Injection Technology Safe, clean, efficient Easy to use, reliable Various types of medicines Introduction Current Ideal Proposed Conclusion
  17. 17. 17 Needle Free Injections Alternates Alternative medication delivery systems include:  nasal sprays and drops  skin patches such as nitroglycerin patches for heart patients  inhalers for asthma which deliver pre-measured doses into the lungs for rapid absorption into the bloodstream  edible vaccine-packed vegetables (in 1998 potatoes developed with genes from the cholera virus to protect against cholera) Introduction Current Ideal Proposed Conclusion
  18. 18. 18 Needle Free Injections Development Needle Free Injector Systems 1940s & 1950s air powered injector systems Gun shaped used propellant gases to force drugs into the skin Multiple inoculations in the military and developing nations Reusable – risk of infection Introduction Current Ideal Proposed Conclusion
  19. 19. 19 Needle Free Injections Development Needle free injectors improved By the 1990s  single dose from serum reservoir  disposable nozzle  use existing medications  inject liquid or powder  self contained propulsion The Cool Click from Bioject Introduction Current Ideal Proposed Conclusion
  20. 20. 20 Needle Free Injections Description How Needle Free Injectors Work force medication at high speed through a tiny hole that is held against the skin ultra-fine stream of high-pressure fluid or powder penetrates the skin to various depths intradermal, subcutaneous, & intramuscular Introduction Current Ideal Proposed Conclusion
  21. 21. 21 Needle Free Injections Description Injection modes Intradermal – very shallow between layers of skin Subcutaneous – adipose or into the fat layer of the skin Intramuscular – deepest type, into muscle tissue Intradermal Subcutaneous Intramuscular Introduction Current Ideal Proposed Conclusion
  22. 22. 22 Needle Free Injections Description Injector design: 3 components Injection device – hand held durable plastic   Disposable needle free syringe – only part that touches the skin, sterilized and disposable after injection   Air cartridge – pressurized metal air cartridge in portable units - larger air container hook ups for in-office systems Introduction Current Ideal Proposed Conclusion
  23. 23. 23 Needle Free Injections Description Injector design: Crossject uses the impact of a spring triggered by the nozzle touching the skin to activate energetic materials which produce gas to inject the serum. Other systems use a re-usable spring to generate the pushing force instead of air. Introduction Current Ideal Proposed Conclusion
  24. 24. 24 Needle Free Injections Description The Crossject Bioject 2000 System System Disposable syringe CO2 Cartridge Bioject 2000 Injector Bioject Gas Tank Attachment Introduction Current Ideal Proposed Conclusion
  25. 25. 25 Needle Free Injections Advantages Needle Free Injectors Advantages:  less drug required to inject the same volume approximately 8% savings in vaccine  improved diffusion and more reliable depth of penetration  reliable penetration means more efficient use of drugs Introduction Current Ideal Proposed Conclusion
  26. 26. 26 Needle Free Injections Advantages Needle Free Injectors Advantages:  improved safety and protecting against infection  higher self-treatment rates  operate with existing formulations which reduces development and clinical trials, and that equals savings Introduction Current Ideal Proposed Conclusion
  27. 27. 27 Needle Free Injections Problems Needle Free Injectors however… are more expensive, for example:    Biojector® 2000 Injector $1200.00 Single use, sterile, disposable needle-free syringes $200.00 (100 syringes per box) Box of CO2 power cartridges $8.00 (10 CO2 cartridges per box) Introduction Current Ideal Proposed Conclusion
  28. 28. 28 Needle Free Injections Conclusion Recap: Hypodermic Needles difficult to master (training) not always effective safety issues (stick injuries, reuse) disposal issues just not well liked (needlephobia) inexpensive Introduction Current Ideal Proposed Conclusion
  29. 29. 29 Needle Free Injections Conclusion Recap: Needle Free Injectors safe & sterile use existing meds & new developments less medicine required reliable depth of penetration efficient use of medication patients like them and use them (self treatment) not inexpensive Introduction Current Ideal Proposed Conclusion
  30. 30. 30 Needle Free Injections Conclusion Conclusion: Needle Free Injectors are more reliable, easier to use, more efficient, much safer and have no disposal problems. Acceptance by patients, continuing developments and lowering costs all make needle free systems the best method for vaccinations, insulin self-treatments, and large or small scale inoculations.
