Abstract

The invention relates to a nasopharyngeal surface anesthesia apparatus comprising a nasopharyngeal surface anesthesia catheter (5) and a syringe (4). The nasopharyngeal surface anesthesia apparatus is used for sufficient deep nasopharyngeal surface anesthesia before sobering nasotracheal intubation and nasopharyngeal deep treatment for a patient, thus preventing the patient from feeling uncomfortable and rejecting when a catheter is inserted into a nasopharyngeal channel or during treatment. The existing nasopharyngeal catheter is provided with a certain amount of outlets of anesthetic, the syringe is provided, and the complete nasopharyngeal anesthesia apparatus is formed; therefore, chances of the patient feeling uncomfortable and rejecting are slimmer, and surgery is smooth. The nasopharyngeal surface anesthesia apparatus is applicable to sobering nasotracheal intubation and deep nasopharyngeal treatment.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a surface anesthesia device for nasopharyngeal cavity. Background technique [0002] During clinical anesthesia induction, in some special cases, the patient should be kept breathing spontaneously and intubated through the nasal cavity and trachea in an awake state. In order to reduce the patient's pain, this requires adequate topical anesthesia for the patient's nasopharyngeal cavity and glottis before tracheal intubation. In addition, good topical anesthesia is also required when performing diagnostic and therapeutic operations on the deep part of the nasopharyngeal cavity. In the prior art, the device mainly used clinically is the spraying method of a topical anesthesia watering can. [0003] The metal nozzle of the surface anesthesia watering can is relatively short, which can exert a good effect on the surface anesthesia of the superficial part of the mouth and...
