Abstract

The invention belongs to the technical field of medical instruments and particularly relates to an otolaryngology dosage adjustable doser. The otolaryngology dosage adjustable doser solves the problemthat a single user cannot complete dosing operation and observation of dosage during dosing operation. According to the scheme, the otolaryngology dosage adjustable doser comprises a transparent syringe and a sleeve arranged at the outlet end of the syringe in a sleeve mode, and one end of the sleeve, which is away from the syringe, is connected with a universal pipe which is connected with a dosing head; the outer wall of one side of the dosing head, which is away from the universal pipe, is provided with an outlet hole, and the top of the dosing head is fixedly provided with a probe; the circumferential outer wall of the syringe is slidingly connected with a fixing ring in a sleeve mode, the inner wall of the fixing ring is provided with a mounting groove in a ring structure, and a sensing ring is mounted inside the mounting groove. The otolaryngology dosage adjustable doser can conveniently enter deep into ear, nose or throat and monitor lesion and achieve observability of dosing processes as well as automatic dosing in a quantitative and adjustable mode, thereby facilitating operation by a single user and saving time and labor.
