摘要：
The present disclosure provides an apparatus for delivering an anesthetic agent to a target tissue in a nasal cavity of a patient. The apparatus includes an elongated shaft with a proximal end and a distal end. The apparatus also includes an absorbent plug coupled to the distal end of the elongated shaft. The absorbent plug is configured to occupy a first volume in a compressed state and a second volume in an uncompressed state. The absorbent plug is configured to store an anesthetic agent and deliver the anesthetic agent to the target tissue in the nasal cavity by contacting the target tissue. The apparatus also includes a sheath at least partially covering the absorbent plug. The sheath retains the absorbent plug in the compressed state when positioned at least partially over the absorbent plug, and removal of the sheath allows for the absorbent plug to expand to the uncompressed state.
