FIELD: medicine. ^ SUBSTANCE: invention relates to medical equipment, namely to instrument for introduction of transcutaneous sensor, which contains sensitive part, for instance, for registration of glucose in blood. Instrument for introduction of transcutaneous sensor contains case, sensor case, needle bush, spring element and bearing site. Case is provided with guiding means on its internal surface for guided travel of bearing site. Sensor case contains sensitive part, introduced under the skin. Needle bush contains needle for introduction for puncturing skin. Sensor case and needle bush are connected to each other in a separable way and in their connected state needle for introduction contacts with sensitive part. Bearing site on its internal surface is provided with guiding means which ensures guided travel relative to case between retracted and extended positions. Spring element is connected with trigger means. When trigger means is set into operation sensor case, needle bush and bearing site under the impact of spring element are put into extended position, in which needle and sensitive part can be introduced under the skin. Needle bush and bearing site are provided with inseparable means of fixation. Needle for introduction, at least partially, surrounds sensitive part, introduced under the skin. Introduced sensor of the said instrument for introduction can register glucose in patient's blood. In the second version of implementation of instrument for transcutaneous sensor, needle bush and bearing site are provided with inseparable means of fixation. Lower base of case is made with protruding part. Protruding part forms an angle with needle for introduction in longitudinal direction, setting for the person who introduces the needle the required angle in introduction. ^ EFFECT: instrument for introduction is simple and safe for user in the process of its application and removal after application. ^ 18 cl, 27 dwg |
