摘要

the utility model belongs to the field of medicine, namely, cardiovascular surgery, neurosurgery, trauma and orthopaedics.the device is in the form of a silicone catheter with a central channel with u0437u0430u0433u043bu0443u0448u0435u043du043du044bu043c u0434u0438u0441u0442u0430u043bu044cu043du044bu043c end.in the last set, with the possibility of making it flexible to facilitate the introduction of u043du0430u043fu0440u0430u0432u0438u0442u0435u043bu044c probe into the epidural space.in the side walls of the catheter with the distal end with u043fu0440u044fu043cu043eu043fu0440u043eu0442u0438u0432u043eu043fu043eu043bu043eu0436u043du044bu0445 parties from the central channel alternately arranged and u0444u043eu0442u043eu043fu0440u0438u0435u043cu043d reflector ir.they separated along the catheter relative to each other and are connected with the relevant conclusions on them u043eu043au0441u0438u043cu0435u0442u0440u0438u0438 and microcirculation by laser analyzer u0432u043fu0430u044fu043du043du044bu0445 in its side walls of opticallyx fibre with a protective coating of teflon.the working surface to the outer surface of the catheter u0444u043eu0442u043eu043fu0440u0438u0435u043cu043du0438u043au0430 is nearby, and the reflector is located with the opportunity to ensure u0441u0432u0435u0442u043eu0432u043e the beam in the optical windowlocated on the opposite side wall of the catheter and a u043au043eu043du0443u0441u043eu043eu0431u0440u0430u0437u043du0443u044e form expanding out from the central channel.on the opposite side of the optical window in the side wall of the catheter is placed u0440u0435u043du0442u0433u0435u043du043eu043au043eu043du0442u0440u0430u0441u0442u043du0430u044f mark for between the reflector and u0444u043eu0442u043eu043fu0440u0438u0435u043cu043du0438u043au043eu043c.the utility model provides u043fu0443u043du043au0446u0438u043eu043du043du043e affirmed it implanted in the epidural space, reducing to a minimum the possibility of traumatisation thi u0435u0441u0442u0432u0430 spinal cord. 1, etc., 2).
