An injector for transcutaneously introducing a sensor into a patient, including a cannula, a sensor arranged in the cannula, a base element, a sliding element arranged displaceably on the base element in an injection direction, for transcutaneously introducing the cannula having the sensor into the patient in an injection operation. The cannula has a slot in a longitudinal direction of the cannula. The injector has a holding element arranged displaceably on the base element that, in an ejection operation, prevents the sensor from being pulled out as the cannula is withdrawn, by engaging in a distal end region of the sensor through the slot into the cannula. The holding element and/or base element have at least one fixing arrangement to automatically lock the holding element on the base element when the cannula is introduced transcutaneously into the patient. A method for transcutaneously introducing a sensor into a patient is also provided.

Injector for transcutaneously introducing a sensor into a patient

An injector for transcutaneously introducing a sensor into a patient, including a cannula, a base element, a sliding element arranged displaceably on the base element, for transcutaneously introducing the cannula into the patient in an injection direction, and including an ejection element for automatically pulling the cannula out of the patient counter to the injection direction by the ejection element in an ejection operation. The injector has a locking element for the ejection element such that, in a delivery state, the ejection element is lockable in an energy-charged state, and the sliding element and the locking element are configured to interact indirectly or directly in order, in an injection state, when the cannula is introduced transcutaneously into the patient, to release the locking of the ejection element in order automatically to start the ejection operation.

A system for analyzing a patient using a transcutaneous sensor, having a base unit for attaching to the patient, an injector, releasably connectable to the base unit, for the transcutaneous insertion of the sensor into the patient, and a detection unit, releasably connectable to the base unit, for generating measurement data by the sensor. The base unit has a holding device which is configured to cooperate with the injector and detection unit such that, in a detection configuration with the detection unit arranged on the base unit, a contact pressure is applied to the sensor by the holding device for frictional fixing, and in an injection configuration with the injector arranged on the base unit, a lower contact pressure than in the detection configuration is applied to the sensor by the holding device.
