Description

Oral mucosa exfoliative cell brush

Technical Field

The utility model relates to a cytobrush field, concretely relates to oral mucosa exfoliative cytobrush.

Background

Potentially malignant diseases of the oral cavity have the potential to develop into oral cancer. Clinically common oral potential malignant diseases include oral leukoplakia, oral erythema, oral lichen planus, oral submucosa fibrosis and the like. At present, the cell shedding brush used clinically is slender, and the front end has no brush hair. Due to the complex internal structure of the oral cavity, cells at a plurality of parts are difficult to brush, such as palate, posterior molar region, mouth floor, vestibular sulcus and the like, the operation difficulty of a clinician is high when brushing the cells, the detection effect is influenced by the limited number of the sampled cells, and the patient feels uncomfortable. After the cell brush is taken, the brush handle needs to be cut off by virtue of a pliers, and the operation is complex. Therefore, the cell brush for the oral mucosa, which has the advantages of simple structure, simple and convenient operation and flexible working angle, has important significance for noninvasive diagnosis of potential malignant diseases and oral cancer of the oral mucosa.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an oral mucosa cell brush that drops can all-round brush get the cell that drops of each position mucosa in oral cavity to get the completion back at the brush and impel the plastic pipe box forward, will brush head and brush holder separation.

The utility model adopts the following technical scheme: an oral mucosa exfoliating cytobrush comprises a plastic core, brush hair arranged on the surface of the plastic core, a brush handle detachably connected with the plastic core, and a plastic sleeve movably sleeved on the periphery of the brush handle.

Preferably, the included angle between the bristles and the axial direction of the plastic core smoothly transitions from 180 ° to 90 ° from the end portion to the tail portion.

Preferably, the tail part of the plastic core is provided with a cross-shaped groove, and the end part of the brush handle is correspondingly provided with a cross-shaped bulge which is connected with the brush handle in a matching way.

Preferably, the surface of the handle is provided with a plurality of screw structures.

Preferably, the number of the thread structures is two, and the two thread structures are respectively arranged at the position close to the tail part of the plastic sleeve and the middle rear section of the brush handle

Preferably, the inner diameter of the sleeve is larger than the outer diameter of the handle and smaller than the outer diameter of the plastic core.

The utility model discloses beneficial effect does:

the utility model discloses an in the oral cavity mucous membrane cell brush that drops, the brush holder periphery is located to the plastic sleeve movable sleeve, can follow brush holder axial direction and remove and rotate, after the sampling, can dismantle the plastics core of being connected from the brush holder desorption, conveniently dismantle the plastics core with the brush holder through removing the plastic sleeve.

Drawings

Fig. 1 is a schematic structural view of the present invention;

figure 2 is a cross section of the brush head, the bottom of the plastic core and the front end of the handle.

The labels in the figures are: 1-bristle, 2-plastic core, 3-brush handle, 4-plastic sleeve, 5-brush head cross section, 6-cross groove, 7-cross protrusion, and 8-thread structure.

Detailed Description

The present invention will be further described with reference to the drawings and examples, which should not be construed as a limitation to the present invention.

As shown in figure 1, a brush for exfoliating cells of oral mucosa. Including the brush hair 1 that the multi-angle set up, can fix the plastics core 2 of brush hair 1, connect the brush holder 3 of plastics core 2, the plastics pipe box 4 outside the brush holder 3 is located to the movable sleeve, 3 axial direction slides along the brush holder in plastics pipe box 4, and can rotate in 3 peripheries of brush holder, brush hair 1 is fixed in on the plastics core 2, constitute the brush head, contained angle between brush hair 1 and the 2 axial of plastics core is by the tip to the afterbody by 180 to 90 smooth transition (wherein the free end of plastics core 2 is the tip, the one end of being connected with brush holder 3 is the afterbody), the afterbody of plastics core 2 is provided with cross recess 6, and the tip correspondence of brush holder 3 is provided with the protruding 7 accordant connection of cross, through the connection of dismantling of cross recess 6 and the protruding 7 of cross, makes and can dismantle between plastics core 2 and the brush holder 3 and be connected. The brush holder 3 is externally provided with a plastic sleeve 4, the inner diameter of the sleeve 4 is larger than the outer diameter of the brush holder 3 and smaller than the outer diameter of the plastic core 2, the brush head can be rotated in an auxiliary manner during sampling operation, and the plastic sleeve 4 can be pushed forward after sampling is finished to separate the plastic core 2 from the brush holder 3. The middle part of the brush handle 3 is tightly attached to the plastic sleeve 4 and the rear part of the brush handle is respectively provided with 3 circles of thread structures 8, so that the cell brush is convenient to fix during operation.

When in use, after the part to be inspected is well fixed, an operator takes out the cell brush, lightly pinches the plastic sleeve 4 close to the brush head end with one hand for retention, lightly presses the brush hair 1 to the part to be inspected, and rotates the cell brush handle 3 with the other hand for about 20 circles to take materials. After sampling, the brush head is immersed in the fixing liquid, the plastic sleeve 4 is pushed forward to separate the brush head from the brush handle 3, the bottle cap is tightly covered, the brush is shaken for 10 times, and the brush is placed in a 4-degree refrigerator for storage.

While the foregoing is directed to the preferred embodiment of the present invention, it will be understood that the invention is not limited thereto, and that various modifications and changes can be made by those skilled in the art without departing from the principles of the invention.
