Embodiment 1

[0021] as attached figure 1 , 2 , The saliva DNA collection and preservation bottle shown in 3 includes a preservation bottle body 11, a collection cover 12 used in conjunction with the preservation bottle body 11, and the collection cover 12 includes a connection part 121 connected with the preservation bottle body 11, and a front end of the connection part 121. The hollow collecting part 122 and the sampling part 123 located at the front end of the collecting part 122 . The diameter of the sampling part 123 gradually increases from close to the collecting part 122 to away from the collecting part 122, which is more convenient for sampling; A liquid inlet 124 is provided on the connecting surface of the part 122 , and the sample enters the preservation bottle 11 from the sampling part 123 through the liquid inlet 124 and the liquid flow hole 1211 . The edge of the liquid inlet 124 is provided with a flow guiding structure 125 , which is a flow guiding column extending from ...

Abstract

The invention discloses a saliva DNA (deoxyribonucleic acid) collection and storage bottle. The saliva DNA collection and storage bottle comprises a storage bottle body and a collection cap matched with the bottle body. The collection cap comprises a connection portion, a hollow collection portion and a sampling portion, the hollow collection portion is positioned at the front end of the connection portion which is connected with the storage bottle body, and the sampling portion is positioned at the front end of the collection portion. The end face of the connection portion is provided with a liquid flow hole, and the collection portion and the storage bottle body are communicated through the liquid flow hole. A surface, connected with the collection portion, of the sampling portion is provided with a liquid inlet, and the edge of the liquid inlet is provided with a flow guide structure. The saliva DNA collection and storage bottle has the advantages that firstly, by the aid of the sampling portion fitting a mouth shape, sampling is facilitated, saliva is less prone to splashing all around, and sanitation and convenience are realized; secondly, by arrangement of the multi-section collection cap and a transition structure, a sample can be well protected hermetically, leakage is avoided, and accordingly sample contamination probability is greatly lowered; thirdly, simplicity and convenience in integral structure and operation and suitableness for extensive popularization and utilization are realized.

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...
