Simulated oral cavity device for collecting buccal cigarette dissolved matter and using method thereof

Abstract

The invention relates to the technical field of simulated oral cavity devices and relates to a simulated oral cavity device for collecting buccal cigarette dissolved matter and a using method thereof. The simulated oral cavity device dissolves out and collects matter in buccal cigarettes in a simulated buccal state and comprises two layers of thin films, a constant-temperature water bath and a guide-out end capillary tube, edges around the thin films are in press-fit airtight to form a film wrapping jacket, an interlayer for placement of a buccal cigarette sample is arranged between the thin films, and infiltration liquid is guided into the interlayer by adopting a method of membrane permeation or capillary tube diversion to infiltrate the buccal sample; the film wrapping jacket is put below liquid level of liquid in the constant-temperature water bath, and one end of the guide-out end capillary tube extends into the interlayer while the other end of the same is connected with a dissolved liquid collection component. The simulated oral cavity device enables contact area of the buccal sample and the thin films to be consistent with that in a real oral cavity; during an experiment, the buccal sample is in a temperature environment in a simulated oral cavity, and pressure of the liquid can simulate pressure between gingiva and cheek.

Description

technical field

[0001] The invention relates to the technical field of simulated oral cavity devices, in particular to a simulated oral cavity device for collecting snus extracts and a method for using the same. Background technique

[0002] Chinese invention patent "Device and Simulation Method for Simulating Mouth Dissolution of Smokeless Tobacco Products", publication number: 104198662A, the device includes a constant temperature water bath box, a dual-channel peristaltic pump, and a collection bottle, all of which are placed in the constant temperature water bath box The artificial saliva and the artificial oral cavity device in the artificial oral cavity device are provided with a dissolution vessel for placing the oral-type smokeless tobacco product and containing the liquid. The liquid dissolution core unit used as a mouth-type smokeless tobacco product is an open container. Although the container is placed in a constant temperature water bath, the smokeless tobacco p...
