Description

Saliva collector

Technical Field

The utility model relates to a saliva collector belongs to biological sample collection equipment field.

Background

When the gene detection is carried out, one type of sample is saliva, a direct saliva collection method is adopted in part of experiments when the saliva is collected, and a saliva collector is needed at the moment.

The saliva collector in the prior art has some technical defects. For example, most of the collecting funnels of the saliva collectors are in a long and narrow oval structure or a round structure, the collecting funnels are large in size and occupy large space, and some structures even prevent the oral cavity from being opened sufficiently, so that the saliva can be spitted inconveniently. And the preserving fluid of a plurality of saliva collectors is stored in the funnel cover and sealed by a sealing film, so that the saliva collector can be punctured by accident. In addition, some saliva is mixed with impurities, which brings inconvenience to saliva collection.

the funnel comprises a funnel body and is characterized in that three creases which are intersected at the bottom of the funnel body are respectively formed on two sides of the funnel body, pull rings are arranged on the tops of the creases in the middle of the two sides, the funnel body is enabled to be folded or unfolded along the creases through the pull rings, and a filter layer is further arranged on the funnel body close to a pipe orifice;

the utility model discloses a saliva sampler, including the sample cell, including the mouth of pipe, saliva collector, side cap, thorn post, seal membrane, saliva collector, saliva.

Further, the filtering layer is a filtering membrane, and the filtering membrane is a microporous filtering membrane or an ultrafiltration membrane.

Further, the filter layer is a filter plate, and the filter plate is a non-asbestos multi-fiber sterilization and clarification filter plate.

Furthermore, the funnel body is made of TPE-U or soft rubber materials.

Further, the reservoir is fixedly connected to a side wall inside the sample tube.

The beneficial effects of the utility model reside in that: the funnel body adopts a foldable design, so that the packaging space is greatly reduced; through be provided with the accumulator in gathering the intraductal, and the side of gathering the pipe is provided with the side cap that has the thorn post, can make the saliva of sending into to the user and the interior liquid medicine rapid combination of container, reach the effect that improves effective sample content.

The above description is only an overview of the technical solution of the present invention, and in order to make the technical means of the present invention clearer and can be implemented according to the content of the description, the following detailed description is made with reference to the preferred embodiments of the present invention and accompanying drawings.

Fig. 2 is a partial structural schematic diagram of fig. 1.

Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

Referring to fig. 1 to 2, a saliva collecting device according to a preferred embodiment of the present invention includes a sample tube 2 and a collecting funnel 1, wherein the sample tube 2 includes a tube opening 21, and the collecting funnel 1 includes a funnel body 11 and a connecting member 12 connected to the funnel body 11 and detachably connected to the tube opening 21. In this embodiment, the funnel body 11 is made of TPE-U or soft rubber. Indeed, in other embodiments, the material of the funnel body 11 may be other, depending on the actual situation, and is not limited herein. Funnel body 11 with mouth of pipe 21 communicates with each other, mouth of pipe 21 is provided with first screw thread, connecting piece 12 inboard be provided with first screw thread carries out threaded connection's second screw thread, funnel body 11 passes through connecting piece 12 detachable sets up on sample tube 2.

Three intersection have been seted up respectively to funnel body 11 both sides in the crease 111 of funnel body 11 bottom, the top of crease 111 in the middle of the both sides is provided with pull ring 112, through pull ring 112 makes funnel body 11 folds or opens the action along crease 111, funnel body 11 is close to mouth of pipe 21 department still is provided with filter layer 13. In this embodiment, the filtering layer 13 is a filtering membrane, and the filtering membrane is a microporous filtering membrane or an ultrafiltration membrane.
