Abstract
This utility model provides a kind of nasopharynx brush, and described nasopharynx brush is a kind of brush that conveniently can obtain nasopharynx part exfoliative cyte.By can the connecting portion of continuous bend couple together between nasopharynx brush first handle bar described in the utility model and the second handle bar, can according to the angle of the natural anatomic form adjustment brush body of each experimenter's nasopharynx part, conveniently arrive position of drawing materials, alleviate the misery of patient, also reduce the complexity of medical worker's operation, shorten sample time; Second handle bar end is provided with anti-skidding spot-like projections, prevents nasopharynx brush from dropping from hands; Nylon flocking brush is soft, adhesion is strong, can obtain more nasopharynx part exfoliative cyte, conveniently carry out further Biological Detection.Nasopharynx brush described in the utility model is drawn materials to operate and is only needed very simply to train, and the medical worker such as doctor, nursing staff can operate clinically.
Description
Technical field
This utility model relates to a kind of brush, is specifically related to a kind of nasopharynx brush.
Background technology
Nasopharyngeal carcinoma is a kind of high aggressive, high metastatic malignant tumor, is widely current at southern china and south east asia.Although patient's overall survival in nasopharyngeal carcinoma early clinic stage reaches about 90%, be nasopharyngeal carcinoma late period during most patient assessment, its survival rate is lower than 50%; Recurrence after treatment of nasopharyngeal carcinoma and metastasis further cause worse prognosis.Therefore, the early diagnosis of nasopharyngeal carcinoma and treatment are in time the key breakthrough points improving survival, improve prognosis clinically.
The goldstandard of nasopharyngeal carcinoma diagnosis carries out biopsy under nasopharyngeal endoscope to draw materials, and carries out pathological diagnosis afterwards by pathologist.Due to wound of having drawn materials, drawing materials and organize little and rely on perusal under mirror, therefore about having the patient of 10% to diagnose when drawing materials first unsuccessfully, doctor and patient need face again or repeatedly draw materials or the choice of follow-up observation, easy delay treatment.The sample at nasopharynx pathological changes position can adopt the method for nasopharynx brush directly to obtain, this method of drawing material not only have painless, without invasive advantage, exfoliative cyte due to the acquisition of nasopharynx brush directly can reflect the characteristic of nasopharyngeal carcinima, therefore the biomarker that the examination carrying out Molecular biology for nasopharynx brush sample finds nasopharyngeal carcinoma special, clinician can be helped to carry out quick diagnosis to nasopharyngeal carcinoma, and in the curative effect monitoring of nasopharyngeal carcinoma with play larger assosting effect in following up a case by regular visits to.
The design of common Uterine neck bush continued to use by nasopharynx brush conventional on the market at present, brush body is type linearly, special physiological structure not for nasal cavity and nasopharynx part does suitable optimization, operate inconvenience clinically, be unfavorable for the histiocyte of Obtaining Accurate nasopharynx part, not only add the time of censored sample, also bring more misery to patient.
Utility model content
The purpose of this utility model is to overcome weak point that prior art exists and provides a kind of nasopharynx brush this utility model nasopharynx brush and solve and use nasopharynx brush can not accurate, convenient problem of drawing materials at present.
For achieving the above object, the technical scheme taked: a kind of nasopharynx brush, described nasopharynx brush comprises brush and handle bar, described handle bar is made up of the first handle bar, connecting portion and the second handle bar, described brush is connected with described first handle bar, described first handle bar is connected with described second handle bar by described connecting portion, and described connecting portion is can the connecting portion of continuous bend.
Preferably, described brush is made up of brush handle bar and the swab be arranged on described brush handle bar.
Preferably, described brush handle bar is plastic handgrip bar, and described swab is nylon flocking swab.
