Abstract

A means is provided for cooling a cold-congealable fluid in simultaneous contact with a probe and a foreign body imbedded in the skin thereby forming a substantial bridge between probe and object so that a pulling force can be exerted on the object to effect its removal.

Claims

1. A device for removing splinters and thorns comprising a heatconductive probe, a cold-congealable fluid adhered to said probe, and a cooling means,capable of applying freezing temperature to said fluid, said cooling means being applicable to said fluid via said heat-conductive probe.

2. A device for removing splinters and thorns comprising a heat-conductive probe, a cold-congealable fluid adhered to said probe, a refrigerant reservoir, a refrigerant, said refrigerant being contained in said reservoir, a valving means, said valving means applying to said refrigerant reservoir, and an essentially tubular refrigerant conduction means, said refrigerant conduction means operable between said valving means and said heat-conductive probe to apply freezing temperature to said fluid via said probe.
