Abstract

The invention discloses a saliva DNA collection bottle, which comprises a storage bottle body and a collection cover used in conjunction with the bottle body, the collection cover includes a connection part connected with the storage bottle body, a hollow hole located at the front end of the connection part The collection part and the sampling part located at the front end of the collection part, the end surface of the connection part is provided with a flow hole communicating the collection part and the storage bottle, the connection surface of the sampling part and the collection part A liquid inlet is provided on the top, and a flow guide structure is provided on the edge of the liquid inlet. Advantages of the present invention: (1) It is installed in the sampling part where the mouth shape can be well matched, which is convenient for sampling, and it is not easy to splash around, which is more hygienic and convenient; (2) It adopts multi-section collecting cover design and transition structure setting , the protection of the sample is good, it will not leak out, and the probability of sample contamination is greatly reduced; (3) The overall structure is simple and convenient to operate, suitable for widespread use.

Description

technical field [0001] The invention relates to a sample collection bottle, in particular to a saliva DNA collection and preservation bottle, which belongs to the field of medical examination. Background technique [0002] Human saliva contains exfoliated cells of the oral mucosa. Collecting saliva as a DNA sample is widely used because it is non-invasive and simple. What existing saliva collector has is to collect saliva with cotton swab, more loaded down with trivial details. The existing invention patent "Double-head Saliva Collector" (China Patent No. 200620123835.7) consists of three parts: a threaded sampling rod, a cylindrical main pipe and a sample outlet cover. The sampling rod is composed of three structures, the upper cover, the plunger and the absorbent cotton. When sampling, put the absorbent cotton end of the sampling rod into the mouth to make it stained with saliva sample, then put the sampling rod back into the tubular main tube, tighten the bottle cap, un...
