Abstract
An infusion set has an insertion device that inserts a cannula and introducer needle fully into a patient, and then fully removes the introducer needle with one user motion. In some examples the insertion device does not permit partial insertion or incomplete introducer element removal.
Claims18
An infusion set having a full insertion and full removal pathway, comprising:
- a base portion having an adhesive backing that adheres to a patient's skin;
- a disposable insertion device which may be connected to the base portion during the insertion of the cannula and introducer elements;
- an insertion mechanism in the insertion device constructed to insert a cannula/introducer needle pair under the skin of a patient;
- a removal mechanism in the insertion device constructed to remove the introducer needle;
- an actuating device in the insertion device that is engageable by the patient or caregiver, the actuating device coupled to the insertion mechanism and to the removal mechanism;
- and
- wherein the actuation device is constructed to first engage the insertion mechanism to insert the cannula/needle pair, and later to engage the removal mechanism to remove the introducer needle.

- a base portion having an adhesive backing that adheres to a patient's skin;
- a disposable insertion device which may be connected to the base portion during the insertion of the cannula and introducer elements;
- an actuating device in the insertion device that is engageable by the patient or caregiver;
- a cannula and introducer needle pair in the insertion device when the actuating device is in its initial position;
- wherein when partially engaged, the actuating device has operably engaged the cannula/needle pair to insert the cannula/needle pair fully under the skin of the patient;
- and
- wherein when fully engaged and in its final position, the actuating device has operably engaged the introducer needle pair to remove the introducer needle from the patient and back into the disposable insertion device.

- a disposable insertion device which may be connected to the base portion during the insertion of the cannula and introducer elements;
- an actuating device in the insertion device that is engageable by the patient or caregiver;
- a cannula and introducer needle pair in the insertion device when the actuating device is in its initial position;
- an energy capture mechanism that stores kinetic energy as the actuating device is moved from its initial position to its final position;
- wherein when fully engaged and in its final position, the actuating device has operably engaged the cannula/needle pair to insert the cannula/needle pair fully under the skin of the patient;
- and
- wherein after the cannula/needle pair is fully inserted, the energy capture mechanism releases energy to remove the introducer needle from the patient and back into the disposable insertion device.
