摘要

Device (11) for removing a tick from a puncture site on the skin comprises devices for surrounding the tick with a freezable or hardenable liquid. Preferred Features: The device consists of a container (1) filled with refrigerant and attached to a tubular hollow pin (2) which is inserted in a sleeve (5) closed at one end and is provided at the end facing away from the container with an external thread (3). The external thread is screwed into an internal thread in the sleeve to form a spiral channel for the refrigerant. The base of the sleeve and its outer parts form the freezing zone (4) in the region of the channel. The sleeve consists of a good heat-conducting material, especially metal, in the region of the freezing zone and of a poorly heat-conducting material outside the freezing zone. The hollow pin consists of a good heat-conducting material, especially metal, or a poorly heat-conducting material.
