Claims15
A hand-held fluid delivery apparatus, comprising (a) a syringe barrel having a fluid receptacle;
- (b) a plunger disposable within the fluid receptacle of the syringe barrel and moveable along a length of the barrel along a longitudinal axis;
- and (c) a retractor connected to the plunger at its proximal end, for injecting a liquid into a target surface through the end of the syringe barrel, whereby the plunger can be further advanced relative to the barrel by retracting the barrel away from the surface.
A hand-held fluid delivery apparatus, comprising (a) a syringe barrel having a fluid receptacle;
- (b) a plunger disposable within the fluid receptacle of the syringe barrel and moveable along a length of the barrel along a longitudinal axis;
- and (c) a retractor connected to the plunger at its proximal end, for injecting a liquid into a target surface through the end of the syringe barrel, whereby the leading distal edge of the retractor encounters the teat surface, the syringe barrel is required to retract proximally, thereby retracting the syringe barrel tip out of the teat canal and filling the now evacuated teat canal.
A method for reducing the incidence of mastitis in an animal by introducing a composition into the teat canal of the animal comprising the steps of:
- (a) inserting the tip of a syringe into the teat canal;
- (b) injecting a sealant liquid into the teat;
- (c) retracting the syringe barrel tip out of the teat canal;
- and
- (d) expelling the final portion of sealant liquid to fill the now evacuated teat canal.
