Frequently Asked Questions: Application of Medication

  1. Application of Medication
    1. How does the vaccine or medication get into the patient/animal if there is no needle to pierce the skin?
    2. The vaccine or medication is forced under pressure through a tiny, sapphire crystal orifice just .008" or .010" in diameter (both orifices are provided with the unit). The pressurized medication exits in a thin jet with sufficient force to enter the skin. By adjusting the pressure, injections are placed at a pre- selected depth including intradermal, subcutaneous and intramuscular.

    3. How do you know if the medication is being injected to the right depth?
    4. Your AGRO-JET#174; will include a chart with recommended pressures for your specific application. Correct placement is easily verified by touch; subcutaneous injections are smooth and rounded whereas intramuscular injections are pointed and of reduced diameter.

    5. How is the injector supplied with vaccine?
    6. The AGRO-JET#174; unit includes a pair of 60cc syringes that draw medication in the conventional manner from standard containers. The syringe is then attached to a flexible, transparent tube that draws fluid to the jet orifice with the loaded syringe clipped onto a convenient cradle atop the injector. Bubbles are cleared by applying pressure to the syringe until a steady stream is achieved, just as one would with a conventional syringe. The AGRO-JET#174; includes the clip-on cradle for the 60cc syringe and another for 100 ml bottles. Optional containers are designed to clip onto a vest and are available in 500cc and 1000cc sizes.

    7. What is the highest dose that can be injected and is it variable?
    8. The AGRO-JET#174; can deliver up to a 5cc injection with larger doses delivered by repeat injection to surrounding areas. The highest dosage model is fully adjustable from 0.1cc to 5.0cc.

    9. Does the injector have to be in contact with the patient/animal?
    10. Yes, the injector must be in contact with the animal for the length of the injection (about 1 second). The injector should also be held at a right angle to the skin.

    11. How do you know if an injection was successful?
    12. The point of entry can be inspected by touch (see also the answer to question 2 above). It will, however, be very evident if an injection was not successful as you will see the bulk of the intended injection running down the surface of the skin. Once you perform several injections, you will develop a sense for the sound and feel of a successful injection.

    13. Is the injector limited to specific medications and supplements?
    14. The injector is designed for mass-vaccination with all liquid medications currently used in conventional hypodermics.

    15. Can the AGRO-JET® be used on humans?
    16. The AGRO-JET®'s human counterpart is called the "MED-JET®" and is approved by Health Canada for use on humans. Indeed, the MED-JET® is used in Quebec each year to give the "Flu shot". AGRO-JET® should not be used on humans.

    17. Do the patients/animals feel anything?
    18. The injections are virtually painless because there is no needle piercing the skin. The patient/animal, however, will feel the fluid entering during the injection. Any visible reaction by the patient/animal is more commonly a startle response to the sound of the jet. Rarely does the patient/animal display the characteristic flinch experienced with conventional needle injections.

    19. Conventional needle immunology can cause abscesses and cysts. How does the AGRO-JET® compare?
    20. Cysts and abscesses are caused by tissue damage inflicted by the needle at point of entry. The AGRO-JET® eliminates the occurrence of abscesses and cysts with little or no trauma to tissue. Its patented process delivers any vaccine or medication in a fine jet at low-pressure thus providing safe and painless entry with little or no trauma to the tissue at point of entry.
