Abstract
The utility model discloses an oral cavity cytology brush constituted by a brush head, a brush rod, brush hairs, and a handle. The brush head adopts an elastic material, is in the shape of a ball, and can be used to prevent a damage on an oral mucosa of an examinee during the operation. The brush hairs are vertically disposed on the brush rod in a spiral arrangement, and the brush hairs are integrally in the shape of a truncated cone, because the front part of the whole brush hairs is short and the rear part is long. The brush rod is made of a bendable metal material, therefore the curvature and the shape of the metal rod can be adjusted at will according to a sampling position. The handle is provided with a stress concentrated annular groove, which is easy to break, therefore the brush head, the brush hairs and the brush rod after the sampling can be disposed in a container after being taken down, and the preservation and the delivery of the cell specimen can be facilitated. Compared to other samplers, the cytology brush more accords with the ergonomic design, has a better cell acquisition effect, and is especially suitable for being used as the sampling tool of the oral cavity cell pathology.
Description
Technical field
This utility model relates to a kind of apparatus that is applicable to that the clinical middle oral mucosa exfoliative cyte of medical treatment are collected, and is a kind of disposable novel Stomatocyte brush, belongs to technical field of medical instruments.
Background technology
In the Clinical Laboratory; Surgeon dentist generally carries out the oral disease inspection through perusal and iconography to the person under inspection; Can't directly carry out analytical test to BIAO and BEN; Must use the cell of sampling instrument boil on the nape opposite the mouth chamber mucosa to sample, and cell is stored in slide, special container or the solution, transfer to the laboratory analysis of testing again.Present known Stomatocyte sampler, sampling head comes in every shape, and what have is made up of spongy body and plug, and the sampling head that has is entwined by fiber, and cell collection and releasing effect are very poor; The bristle that has is single row's structure or towards single, be difficult for implementing rider-type brush and get; The brush holder support material that has is hard, is unfavorable for adapting to the changeable surface texture of shape in the oral cavity; The handle that has is long, and frangible not, the passing on and deposit of the convenience of influence operation and BIAO and BEN; The brush that has is hard, can bring misery to the person under inspection in the use.
The utility model content
The purpose of this utility model is to provide a kind of disposable Stomatocyte brush, to improve the design defect of existing Stomatocyte sampler, doctor and person under inspection's comfort level, convenience and cell collection efficient in the raising use.
In order to reach above-mentioned purpose, this utility model provides following solution:
A kind of Stomatocyte brush is to be made up of brush, brush holder support, bristle and handle, and brush is an elastic material, and is spherical shape.
Said bristle is arranged perpendicular on the brush holder support in the shape of a spiral, and preceding short back is long, makes bristle integral body be round table-like.
Said brush holder support is to be processed by flexible metal material.
Said handle is provided with the annular groove of a stress concentration, and the contiguous brush holder support of annular groove is easy to fracture.
The total length of said Stomatocyte brush 14cm (centimetre)-16.5cm between.Wherein, the length of brush holder support is between 2cm-2.5cm; The length of handle is between 12cm-14cm; Annular groove leaves the distance of brush holder support near-end between 1.5m-2.5cm.
When this utility model used, the doctor enjoined the person under inspection to open one's mouth earlier, behind the position of confirming to be fit to of drawing materials; The Stomatocyte brush is stretched to the position of drawing materials, bristle is close to mucous membrane surface, rotation 5-8 circle; If the surface irregularity of target mucosa then bends to the curvature that adapts with brush holder support, get cell at this surface rider-type brush then; Draw materials finish after, preservation is fixed on the surface that can be directly the bristle cell be evenly coated in microscope slide, also can be from the annular groove handle that fractures; The brush holder support end is inserted in the fixative in the container analysis that the BIAO and BEN after fixing can supply cytodiagnosis or DNA.
The advantage of this utility model mainly contains:
One, brush is an elastic material, is spherical shape, in the time of can avoiding operating person under inspection's oral mucosa be caused unnecessary damage;
Two, bristle is arranged perpendicular on the brush holder support in the shape of a spiral, and preceding short back is long; It is round table-like that overall appearance is; Ergonomic design has more greatly increased effective contact area, and the bristle of diverse location is stressed balanced more; Help being rotated or rider-type brush is got cell, improve the efficient of cell collection;
Three, brush holder support is to be processed by flexible metal material, can adjust the angle and the curvature of brush holder support arbitrarily according to different surface structure in the oral cavity, guarantees not exist when drawing materials the dead angle;
Four, handle is provided with the annular groove of a stress concentration, is easy to fracture, and helps fixing immediately, preserving and transport behind the specimen sampling, has greatly improved the suitability;
Five, the total length of novel Stomatocyte brush meets clinician's operating habit, the burden sense of having avoided long handle to bring between 14cm-16.5cm; The length of brush holder support has guaranteed to collect enough diagnosis cells between 2cm-2.5cm; Annular groove leaves the distance of brush holder support near-end between 1.5m-2.5cm, has avoided long distance to influence BIAO and BEN depositing in generic container, has improved its versatility.
Description of drawings
Fig. 1 is the overall structure sketch map of this utility model.
The specific embodiment
Following structure accompanying drawing and specific embodiment are done further detailed description to this utility model.
As shown in Figure 1, this utility model is combined by brush 1, brush holder support 2, bristle 3 and handle 4; Brush 1 is an elastic material, and is spherical shape; Bristle 3 is arranged perpendicular on the brush holder support 2 in the shape of a spiral, and preceding short back is long, makes bristle integral body be round table-like; Brush holder support 2 is to be processed by flexible metal material, can adjust the curvature and the shape of Metallic rod according to the position of sampling arbitrarily; Handle 4 is provided with the annular groove 5 of a stress concentration, and annular groove 5 contiguous brush holder supports 2 are easy to fracture; The total length of this novel Stomatocyte brush is 16cm, and the length of brush holder support 2 is 2.5cm, and the length of handle 4 is 14cm, and annular groove 5 is 2cm from the distance of brush holder support 2 near-ends.
When using this utility model, the doctor holds handle 4 earlier, enjoins the person under inspection to open one's mouth, and observes intraoral clinical sign; Behind the position of confirming to be fit to of drawing materials, the Stomatocyte brush is stretched to the position of drawing materials, bristle 3 is close to mucous membrane surface; Rotary handle 4 about 5-8 circles are if the surface irregularity of target mucosa then bends to the curvature that adapts with brush holder support 2; Get cell at this surface rider-type brush then, draw materials finish after, preservation is fixed on the surface that can be directly the cell on the bristle 3 be evenly coated in microscope slide; Also can brush holder support 2 ends be inserted in the fixative in the container analysis that the BIAO and BEN after fixing can supply cytodiagnosis or DNA from annular groove 5 handle that fractures.
