Embodiment 1

[0017] Example 1. See figure 1 , figure 2 In this example, the oral mucosal scraper is formed by integral injection molding of a 107mm-long handle 1 and a 13×6mm scraper 2 at one end (the size of the scraper is suitable for the oral cavity, generally not exceeding 25×15mm), and the cross section of the tail end of the handle is positive six Shaped to facilitate rotation during washing. The protrusions 3 on both sides of the scraper are 8 rows of square convex columns with a square cross section, each row has 5, and the square convex columns in the even-numbered and odd-numbered rows are arranged in a staggered manner. The height of the entire row of square bosses gradually decreases from 4mm at the far end of the scraper to 2mm toward the handle. There are two through-holes 2-1 on the scraper gap between two adjacent convex post rows, see image 3 . The plane of the scraper is higher than the root of the square convex column (it is advisable not to exceed the height of t...

Embodiment 2

[0018] Example 2. See Figure 4 In this example, the oral mucosa scraper has a scraper 2 at one end of the handle 1, and 28 convex columns 3 with arc-shaped cross-sections on both sides of the scraper, and the convex columns are arranged in a 4×7 rectangular lattice matrix. There are 2 through holes 2-1 between every two rows.

Abstract

The invention relates the oral mucosa agent. The invention improves the effects of collection and elution. The one end of hand handle 1 of oral mucosa agent has striking board 2, and the two sides of striking board have ridges 3. Between ridges 3 there are via holes(2-1).

Description

technical field [0001] The invention relates to an oral appliance, in particular to an oral mucosa scraper. Background technique [0002] Oral mucosa sampling in the prior art does not have a special device, and is generally completed by wiping the sampling site with a cotton swab and then washing it in a reagent. Wipe with a cotton swab, the amount of collected material varies greatly, which affects the analysis of the next step, and the cotton swab itself has an adsorption effect, and its collection and elution effects are not ideal. Chinese patent document CN1491621A discloses a kind of "oral mucosa sanitary ware", which is a rod-shaped object, and one end adopts a cleaning head with regular or irregular concave-convex pattern texture made of high-molecular polymer foaming porous material. Scrape the oral mucosa into the bumps of the pattern. However, the cleaning head of this sanitary ware is a foaming porous material, which also has an adsorption effect, and the effec...
