WHAT IS IT ?
3
Needle-free injection systems are novel ways to introduce various medicines into patients without piercing the skin with a conventional needle.
Needle-free injection techniques can be used to administer vaccinesand medications in the pork industry.
They are promoted as a possible option for patients with needle phobia
COMPONENTS

Giving a Needle- free Injection[1]
Fill syringe with injectate
Insert syringe into Biojector
Hold at 90º with firm pressure at injection site
Pull actuator, count to three, maintain pressure
Remove device and hold pressure at site
( patient or parent can hold )
Entire process is fast and easy

Dispersion Patterns: IM Injection
Spherical bolus
lowest possible
SA/V ratio limited tissue
disruption
Amplified dispersion
medication
forced at high speed through a tiny orifice
very high SA/V ratio
enhanced tissue disruption
Injection event lasts less than 0.5 sec.

BENEFITS OF NEEDLE-FREE INJECTIONS[2]
Eliminates needle phobia
Increased patient compliance
Higher dispersion pattern
Lower pain & stress
Targeted immune response (eg. Vaccine)
Faster injection time (0.5 sec.)

APPLICATIONS
11
1. Intramuscular, subcutaneous and intradermal administration of Vaccinese.g. smallpox, polio, measles
2. Intradermal administration of hormonese.g. growth hormone
3. Intradermal administration of anestheticse.g. Lidocaine
4. Subcutaneous administration of insulin.
5. Used in the treatment of migraine e.g. sumatriptan
It uses pressure from a
spring loaded piston to
create a fine stream of
insulin through a small
bore nozzle, delivering
insulin to the subcutaneous
layer.
12
Recojet is India’s first needle-free insulin delivery device.

THE FUTURE
16
Many of these needle-free alternative technologies are in the development stage.
Inhalers are being improved as are nasal sprays, forced air injectors and patches.
In the future, other foods may be genetically enhanced to deliver vaccines and other drugs.
These include foods like bananas and tomatoes.
