摘要：
The present disclosure provides an apparatus (200) for delivering an anesthetic agent (222) to a target tissue in a nasal cavity (100) of a patient. The apparatus (200) includes an elongated shaft (212) with a proximal end (214) and a distal end (216). The apparatus (200) also includes an absorbent plug (220) coupled to the distal end (216) of the elongated shaft (212). The absorbent plug (220) is configured to occupy a first volume in a compressed state and a second volume in an uncompressed state. The absorbent plug (220) is configured to store an anesthetic agent (222) and deliver the anesthetic agent (222) to the target tissue in the nasal cavity (100) by contacting the target tissue. The apparatus (200) also includes a sheath (224) at least partially covering the absorbent plug (220). The sheath (224) retains the absorbent plug (220) in the compressed state when positioned at least partially over the absorbent plug (220), and removal of the sheath (224) allows for the absorbent plug (220) to expand to the uncompressed state.
