Claims
1. Apparatus for injecting a fluid into body tissue, the apparatus comprising: a hollow needle; and fluid delivery means, wherein the apparatus is adapted to actuate the fluid delivery means in use so as to concurrently inject fluid into body tissue during insertion of the needle into the said body tissue.
2. Apparatus as claimed in claim 1 adapted to automatically inject fluid into body tissue during insertion.
14. A method of injecting a fluid into body tissue, the method comprising: injecting the fluid into the body tissue through a hollow needle while the said needle is being inserted into the said body tissue.
[0007]From a first aspect, the present invention provides an apparatus for injecting a fluid into body tissue, the apparatus comprising: a hollow needle; and fluid delivery means, wherein the apparatus is adapted to actuate the fluid delivery means in use so as to concurrently (preferably automatically) inject fluid into body tissue during insertion of the needle into the said body tissue. This has the advantage that the ability to inject the fluid gradually while the needle is being inserted leads to a more even distribution of the fluid through the body tissue. It is also believed that the pain experienced during injection is reduced due to the distribution of the volume of fluid being injected over a larger area.
