Claims5
A method of delivering at least one therapeutic compound to a human or animal in the form of a needleless injection comprising:
- providing an injection device comprising a casing having an aperture and a spring for storing energy, an ejector pin for pushing an injectate through the aperture wherein the injectate comprises at least one therapeutic compound;
- placing the aperture of the device close to or in contact with the skin of a human or animal;
- actuating the device by causing the spring to release its stored energy generating a force that causes the injector pin to engage the injectate and push it out of the aperture as a single unit;
- penetrating the skin of the human or animal with the injectate at a velocity of less than 100 m/s wherein the injectate has a maximum diameter of less than 3 mm and is left in the human or animal and wherein the ejector pin continues to push the injectate beyond the device and into the human or animal.
