A tool for application of a haemostat to a site of bleeding comprises a cylindrical barrel, a plunger slidable in the barrel, the barrel having an outlet end. The outlet end may be configured as a cone or rounded end with a central aperture and longitudinal slots in a cruciform arrangement, or may be left open. The barrel may have a slot alignable with a slot in an inner member for insertion of a haemostat body in the barrel. The barrel and plunger may be separable for insertion of the body into an open end of the barrel.
