Description

A kit for self-collection of oral mucosal cells, nucleic acid pre-extraction and stable storage technical field The invention belongs to the technical field of kits for collecting and preserving exfoliated cells of oral mucosa for personal family health care and / or medicine. Background technique In my country, the incidence of oral cancer accounts for about 3% of all malignant tumors, while in developing countries such as India, the Philippines, Brazil and Sri Lanka, the incidence is higher, accounting for 25% of all malignant tumors. In recent years, the incidence and mortality of oral cancer have been on the rise in my country, the United States, Japan, France, Germany and other countries. Therefore, research on chemoprevention of oral cancer is of great significance. Oral leukoplakia is a precancerous lesion of the oral cavity identified by WHO, and its cancerous rate is 7% to 15%, and heterogeneous leukoplakia can reach 15% to 40%. Therefore, blocking the development ...

Problems solved by technology

However, because different samplers, usually ordinary people, have different sample delivery times, the samples cannot be relatively concentrated. In order not to delay the sample processing time, that is, to ensure that the samples are not spoiled, laboratory inspectors have to conduct a test on a small number of samples.

This wastes the efficiency of laboratory testing and increases the cost of batch testing

In addition, the existing method is that the patients go to the hospital to queue up, and the medical staff distribute the scraping sticks one by one to take samples. If there are many patients and the samples are concentrated, the entrance of the hospital laboratory is very noisy and messy, and the hospital has to manage it. It may be necessary to expand the site or arrange additional on-site management personnel, which increases the cost of the hospital; on the other hand, for medical patients, it is very inconvenient to queue for a long time, and the messy scene also makes the medical patients uncomfortable
