FIELD: medical equipment.
SUBSTANCE: invention relates primarily to a medical apparatus, and mainly to an insertion tool for an intrauterine system used for contraception or meeting other needs for administration of therapeutic active substances. The insertion tool for an intrauterine system comprises an insertion tube, a handle and an indicator mechanism. The insertion tube has a first end and an opposite second end, wherein the first end is designed to operate with detachable placement of the intrauterine system. The handle has a first end part and an opposite second end part, wherein the first end part of the handle is connected to the second end of the insertion tube and the handle is comprised of a manipulator for controlling the movement of the insertion tube relative to the intrauterine system. The indicator mechanism is connected during operation with the insertion tube and the handle. The indicator mechanism is connected with possibility of transmitting signals to the manipulator and is configured to operate providing indicative signals corresponding to the operating steps of the insertion tool and containing at least one light signal, and the indicator mechanism is comprised of an energy source. The indicator mechanism is comprised of at least one light source, control module placed in the handle and an energy source placed in the handle to provide electricity to at least one light source and to the control module. At least one light source is located at the junction of the first end part of the handle and the second end of the insertion tube. The control module is configured to operate controlling at least one light source to provide at least one light signal corresponding to the operating steps of the insertion tool. The insertion tool is configured to perform operating steps including: retraction of at least most of the intrauterine system into the insertion tube; insertion of the insertion tube into the uterine cavity of the uterus at the first insertion depth; the first movement of the insertion tube relative to the intrauterine system; movement of the insertion tube to the second insertion depth; and the second movement of the insertion tube relative to the intrauterine system to release the intrauterine system. The indicator mechanism comprises at least one light source and is configured to operate with: emitting visible light of a first color to indicate that at least most of the intrauterine system is retracted into the insertion tube; continuously emitting visible light of the first color to indicate that the insertion tube is inserted into the uterine cavity of the uterus at the first insertion depth; periodically emitting visible light of the first color during the first movement of the insertion tube; emitting visible light of a second color to indicate the insertion of the insertion tube at the second insertion depth; and terminating emission of visible light of the second color to indicate release of the intrauterine system into the uterine cavity.
EFFECT: invention allows the practicing physician to effectively guide or operate the instrument in conditions of low visibility.
