Nasal cavity part medicine applying device for nursing in otorhinolaryngology department

Abstract

The invention relates to the technical field of medical care nursing, and discloses a nasal cavity part medicine applying device for nursing in otorhinolaryngology department. The nasal cavity part medicine applying device for nursing in otorhinolaryngology department comprises a casing, wherein a liquid suction pipe is fixedly connected to the bottom of the casing; a current-limiting ball and a valve block are movably connected inside the casing; the top of the casing is glidingly connected with a plunger piston rod; the bottom of the plunger piston rod is fixedly connected with a reset spring; a two-way lead screw is movably connected inside the casing; the outside of the two-way lead screw is movably connected with a lead screw slide block; a positioning ring is fixedly connected to theoutside of the lead screw slide block; and a liquid conveying pipe is fixedly connected with the right side of the inside of the casing. Through the cooperative use of the plunger piston rod, the reset spring, the two-way lead screw, the lead screw slide block and the positioning ring, the effect of regulating the dose of sprayed medicine by changing a reciprocating stroke of the plunger piston rod is achieved; the medicine applying effect is effectively ensured; and insufficient dose or dose waste can be avoided, so that the rehabilitation effect of a patient is ensured.

Description

technical field [0001] The invention relates to the technical field of medical care, in particular to a device for applying medicine to the nasal cavity for otolaryngology care. Background technique [0002] Otorhinolaryngology is the surgical discipline that diagnoses and treats the ear, nose, pharynx, larynx, and related head and neck regions. With the advancement and development of science and technology, various medical disciplines have penetrated and promoted each other, expanding the scope of otolaryngology, ear microsurgery, ear neurosurgery, lateral skull base surgery, audiology and balance science, nasal endoscopic surgery, nasal surgery, etc. The emergence of neurosurgery (nose and skull base surgery), head and neck surgery, throat microsurgery, department of voice and speech disorders, and pediatric otolaryngology has greatly enriched the content of otolaryngology.

Problems solved by technology

[0003] When it is necessary to apply medicine to the upper part of the nasal cavity of the ENT department, the existing method of applying medicine is usually sprayed directly through a medicine spraying device, resulting in a limited spraying range, poor medicine application effect, and the length of the nozzle cannot be adjusted during use, thus As a result, it is difficult to apply medicine deep in the nasal cavity, and it is inconvenient to use, and the existing medicine application device cannot adjust the amount of medicine when applying medicine, which is prone to insufficient or overdose of medicine, resulting in poor use effect and affecting the patient's health.
