First Claim
1. An injection device comprising:
- a housing;
a securing mechanism configured to secure the injection device against an injection site of a patient;
a needle insertion mechanism configured to cause insertion of a needle into a patient when the injection device is secured against the injection site of the patient;
a medicament delivery mechanism configured to cause injection of a medicament into tissue of the patient at the injection site; and
a medicament retention sensor configured to detect retention of medicament in the tissue of the patient at the injection site,wherein the injection device is configured to respond to detection by the medicament retention sensor of medicament in the tissue of the patient at the injection site by at least one of causing provision of an alert and suspending or halting the injection of the medicament.
