Hand-operated cooling device for cryotherapy

摘要

A hand-operated cooling device for cryotherapy for treating pain, includes a main body and a receptacle, which can be inserted at least partially into the main body, for the exchangeable accommodation and insertion of a gas pressure vessel. The main body includes a manual gas outlet actuation arrangement, which can effects the outflow of a gas from the gas pressure vessel when the receptacle is inserted. The receptacle includes a cooling surface, which can be cooled by the outflowing gas and by the gas pressure vessel jacket, wherein the gas can be conducted inside the main body and inside the receptacle by a gas conducting arrangement and can exit at the receptacle adjacent to the cooling surface. Commercially available gas pressure vessels, can be inserted into the cooling device, so that a simple and cost-effective use of therapeutic OT medical cryotherapy having a pleasant cooling effect is made possible.

1. Hand-operated cooling device for cryotherapy, comprising a main body and a receptacle that can be at least partially inserted in the main body for the exchangeable receiving and insertion of a gas pressure vessel, where the main body is of a material of low specific thermal conductivity and comprises a gas outlet actuating means which can be actuated manually and bring about outflow of a gas from the gas pressure vessel when the receptacle is in place, wherein the receptacle is of a material of high specific thermal conductivity and comprises a cooling surface that can be cooled by the expansion effect of the outflowing gas inside the cooling device and by the cooling of a gas pressure vessel jacket, where the gas is conducted inside the main body and inside the receptacle by gas conducting means and can exit at the receptacle to the side adjacent to the cooling surface and is conducted away from the cooling surface in such a way that the surface to be cooled is not directly aerated or sprayed with the gas.
