An insertion device and insertion set. The insertion device for inserting at least a portion of at least one piercing member of an insertion set through the skin of a patient includes a device housing, a carrier body and a driver. The carrier body is slidably received within the device housing for movement between an advanced position and a retracted position. The carrier body also includes a receiving structure to support the insertion set in a position with the at least one piercing member oriented for insertion through the skin of the patient at a predetermined or variable angle relative to the skin of the patient upon movement of the carrier body from the retracted position to the advanced position. The driver is operatively coupled between the device housing and the carrier body to urge the carrier body from the retracted position toward the advanced position to place at least a portion of the at least one piercing member of the insertion set thorough the skin of the patient to install the insertion set to the patient. The receiving structure of the carrier body is removable from the insertion set while maintaining the installation of the insertion set to the patient.

The driver is operatively coupled between the device housing and the carrier body to urge the carrier body with a controlled force and speed from the retracted position toward the advanced position to place at least a portion of the at least one piercing member of the insertion set thorough the skin of the patient to install the insertion set to the patient. The receiving structure of the carrier body is removable from the insertion set while maintaining the installation of the insertion set to the patient.

The receiving structure is removable from the insertion set while maintaining installation of the insertion set to the patient.

An insertion set for insertion through the skin of a patient includes at least one piercing member adapted to be secured to an insertion device and a set housing to be removable from the insertion device while maintaining installation of the insertion set. At least a portion of the at least one piercing member is insertable through the skin. The set housing is coupled to the at least one piercing member and is adapted so that it is shaped to fit an insertion device to orient the at least one piercing member for placement through the skin of at least a portion of the at least one piercing member at a predetermined angle relative to the skin to install the insertion set. The at least one piercing member is adapted to be retainable by the insertion device during removal from the insertion set.

An injector is provided for automatic placement of a subcutaneous insertion set such as an infusion set or the like used for delivering a selected medication to a patient. The injector comprises a spring-loaded plunger having a head for receiving and supporting the insertion set in a position for placement of a medical insertion needle through the skin of a patient at a selected insertion site. The plunger head includes a safety lock mechanism for engaging and retaining the insertion set during spring-loaded advancement with a controlled force and speed toward the patient's skin to transcutaneously place the insertion needle. When the plunger head reaches a fully advanced position, with the insertion set placed on the patient, the insertion set is releasible from the safety lock mechanism with minimal force to permit quick and easy separation of the injector. Alternately, in some embodiments, the injector can be displaced away from the patient's skin to separate the insertion needle from the insertion set, while leaving the insertion set in place on the patient.

An injector is provided for automatic placement of a subcutaneous infusion set or the like used for delivering a selected medication to a patient. The injector comprises a spring-loaded plunger having a head for receiving and supporting an infusion set in a position for placement of an insertion needle and related cannula through the skin of a patient at a selected insertion site. The plunger head includes a safety lock mechanism for engaging and retaining the infusion set during spring-loaded advancement with a controlled force and speed toward the patient's skin to transcutaneously place the insertion needle and cannula. When the plunger head reaches a fully advanced position, with the infusion set placed on the patient, the infusion set is releasible from the safety lock mechanism with minimal force to permit quick and easy separation of the injector.
