The specific meaning of the above terms in the creation of the present invention can be understood by those of ordinary skill in the art through specific situations.

The following detailed description of the embodiments of the invention is provided.

A saliva collecting device for gene detection is shown in figures 1 to 3 and comprises a liquid storage pipe 1 and a bearing disc 2, wherein the lower part of the bearing disc is communicated with the upper end of the liquid storage pipe through a hose 3, the lower end of the liquid storage pipe is inserted into a protective cylinder 4, the bottom of the protective cylinder is of a flat-bottom structure and can be used as a bottom support, and the liquid storage pipe can be vertically placed on a table board by means of the protective cylinder;

a seal cover 5 is detachably mounted at an opening at the upper end of the liquid storage pipe, air outlet holes 6 are formed in the part, close to the opening, of the liquid storage pipe, and the air outlet holes are usually uniformly distributed by taking the center of the liquid storage pipe as the center; it should be noted that the outlet at one end of the hose extending into the liquid storage tube is arranged close to the inner wall of the liquid storage tube, so that saliva entering the liquid storage tube can flow downwards along the inner wall of the liquid storage tube. Because the receiving disc and the liquid storage pipe are connected by the hose, the position of the receiving disc is convenient to adjust, and the required position is easier to adjust for sampling.

Generally, above-mentioned clamping ring can be screwed in the liquid storage pipe upper end, promptly, the clamping ring is equipped with the internal thread, and the liquid storage pipe upper end is equipped with the external screw thread, and closing cap threaded connection is on the liquid storage pipe.

In an optional embodiment, the bottom of the receiving tray is of a cone-shaped structure, and the hose is connected to the lowest position of the bottom of the receiving tray, so that the saliva sample can flow from the receiving tray to the liquid storage pipe conveniently and can be collected conveniently.

The sealing cover comprises a cover body and a shielding ring 7, wherein the lower end of the cover body surrounds the outer circumferential surface of the liquid storage pipe, the shielding ring protects the air outlet hole and prevents dust and the like from directly entering the liquid storage pipe through the air outlet hole to cause pollution, the cover body comprises a top plate 8 and a connecting ring 9 at the lower end of the top plate, the outer diameter of the shielding ring is larger than that of the connecting ring, and the shielding ring and the connecting ring are connected through a transition ring 10; an upper interception ring 11 and a lower interception ring 12 are arranged in the liquid storage pipe, a plurality of layers of barrier strips 13 are arranged on the part of the liquid storage pipe between the upper interception ring and the lower interception ring, a plurality of guide strips 14 are fixed on the lower interception ring, the upper ends of the guide strips are higher than the upper surface of the lower interception ring, and the lower ends of the guide strips are suspended.

Generally, the guide strip is S-shaped or wavy, so that a flow path of the saliva sample is prolonged, and the saliva sample is blocked by the upper and lower stop rings and the barrier strip flows.

In an alternative embodiment, a plurality of buffer strips 15 are arranged between the protective cylinder and the liquid storage pipe, and generally, the buffer strips are rubber strips. For example, one side of the buffer strip is adhered to the outer surface of the liquid storage tube, and the other side of the buffer strip is adhered to the inner surface of the protective tube. The protective cylinder can effectively protect the liquid storage pipe, avoids collision and damage, and the buffer strip can play a good role in buffering and avoid impact load from directly acting on the liquid storage pipe.

The saliva sample collecting device is reasonable in structural design, simple and easy to operate in saliva sample collection, the liquid storage tube is good in protection performance and not prone to being collided and damaged, meanwhile, gas in the liquid storage tube is prone to being released, and dust is not prone to invading into the liquid storage tube. It should be pointed out that the saliva sample of accepting the dish collection can get into the liquid storage pipe through the hose to through the downward trickling of liquid storage pipe inner wall, receive the baffle of upper stop ring, multilayer barrier strip, lower stop ring, under the prerequisite that does not influence the saliva sample and flow downwards, can be furthest with impurity interception in the saliva stay, simultaneously, it can make the saliva sample extend to intercept layer upon layer, release the gas in the sample as much as possible, in-process through the guide strip downflow, also can furthest make the gaseous release of inclusion in the saliva.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
