Description

Saliva collector

Technical Field

The application relates to the technical field of medical equipment, especially, relate to a saliva collector.

Background

With the gradual popularization and development of gene detection in modern medical clinical tests, the types of samples for detection are gradually diversified, wherein the saliva samples in the oral cavity of a human body are generally applied to screening and detecting human diseases because the protein composition of the saliva samples is basically the same as that of blood of the human body and the sampling operation is simple. When the saliva sample is used for gene detection, the saliva sample is firstly collected, and the saliva collector is a main tool for directly collecting the saliva sample.

At present, saliva samples for gene detection are mainly collected in 2 modes, one mode is that a nose or pharynx swab is used for wiping the inner wall of the nose or pharynx, so that DNA molecules or RNA molecules are adhered to the swab; the second is to spit the saliva sample directly into a collection container (e.g., a funnel) and collect and store it in a related container (e.g., a collection tube). The first method, although inexpensive, is subject to discomfort for the patient due to the small amount of sample available for collection and the tendency to degrade. The second method is easy to collect sufficient effective sample amount and to preserve the transfer sample, so that various saliva collecting tools are derived. The traditional saliva collector adopts a design in the shape of a syringe and the like, and comprises a collecting rod and a sleeve, and the collector is easily polluted in the collecting process.
