Description

Saliva collector comprising collection funnel convenient to install

Technical Field

The utility model relates to a saliva collector who contains the convenient collection funnel of installation.

Background

In molecular biology research, DNA extraction in blood samples plays an important role in genetic engineering and molecular biology research. The DNA generally used for PGR reaction and other molecular tests is mainly extracted from anticoagulated blood, but blood samples with long storage time can form blood clots even if sodium citrate or EDTA anticoagulant is added, which brings inconvenience to extraction. Meanwhile, the collection of blood causes certain trauma to human body and can be completed only by certain professional skills, so that the wide application of blood as a DNA source is limited.

Human saliva contains oral mucosa cast-off cells, and the collection of saliva as a DNA sample source has the following advantages: firstly, sampling without puncture and injury, and avoiding the pain of blood sampling and the embarrassment of urine sampling; ② some people are not suitable for blood sampling, such as children and old people. Other people resist blood collection, such as patients with certain mental diseases and relatives of the patients; simple and easy, saliva is collected and only needs the centrifuging tube: fourthly, the method is cheap and efficient, does not need to be provided with an injector and a disinfection tool, does not need to train professional bloodletting personnel, and saves a large amount of manpower and material resources; even after storage at room temperature for 2 weeks, the complete genomic DNA was extracted. When collecting samples over a large area, saliva samples are suitable for transfer between laboratories and collection points in various regions. Present saliva collector, the plug is inconvenient, can remain saliva on the collection funnel in addition probably, will reserve certain surplus when leading to saliva collection, otherwise the saliva liquid measure of gathering can not reach the requirement.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the defect that exists among the prior art, provide a saliva collector who contains the convenient collection funnel of installation, portable inserting soon, resistance when reducing the plug and more accord with human engineering, the facial type of mouth of more laminating can reduce saliva collection volume, avoids remaining the saliva on the collection funnel wall.

In order to achieve the purpose, the technical scheme of the utility model is to design a saliva collector comprising a collecting funnel convenient to install, which comprises a collecting funnel and a collecting pipe which are arranged from top to bottom in sequence, wherein the lower end of the collecting funnel is provided with a convenient structure for installation; the collection funnel is connected with a saliva storage device for storing stable liquid for ensuring the saliva and the saliva storage stable liquid to be uniformly mixed. The setting of the convenient structure of installation for portably insert soon, resistance when can reducing the plug, abandon the collection funnel after the saliva of being convenient for is gathered fast, also makes things convenient for the quick installation of collection funnel before gathering.

A further technical scheme is that the convenient structure of installation is used for reducing the perpendicular muscle of plug resistance including a plurality of interval setting on the outer wall of collection funnel lower extreme. The vertical ribs arranged at intervals can reduce the resistance during plugging.

The further technical proposal is that the collecting funnel comprises an upper end in the shape of a conical shell or an elliptic conical shell and a lower end in the shape of a circular tube.

The collecting pipe is in threaded connection with the collecting funnel through an external thread matched with the internal thread; gather the funnel including upper end and the lower extreme that is the circular cone shell form, the lower extreme includes the pipe form outer wall, and pipe form outer wall bottom fixed connection ring blind hole shape cover is equipped with the clearance that is used for keeping in the saliva between ring blind hole shape cover and the pipe form outer wall. The gap is arranged for temporary storage of saliva, and the allowable storage capacity of the saliva of the collecting funnel is properly enlarged.

The utility model has the advantages and the beneficial effects that: the portable quick plug can reduce resistance during plugging and better accord with ergonomics, is more fit with the facial type mouth, can reduce saliva collection amount, and avoids the saliva remained on the wall of the collection funnel. The collection funnel is discarded fast after being convenient for saliva is gathered, also makes things convenient for the quick installation of collection funnel before gathering.

Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

The first embodiment is as follows:

as shown in fig. 1, the utility model relates to a saliva collector comprising a collecting funnel convenient to install, which comprises a collecting funnel 1 and a collecting pipe 2 which are arranged from top to bottom in sequence, wherein the lower end 5 of the collecting funnel 1 is provided with a convenient structure for installation; the collection funnel 1 is connected with a saliva storage device for ensuring the saliva and the saliva storage stable liquid to be uniformly mixed. The convenient structure of installation is used for reducing the perpendicular muscle 3 of plug resistance including a plurality of interval setting on 5 outer walls of collection funnel 1 lower extreme. The collecting funnel 1 comprises an upper end 4 in the form of a conical shell and a lower end 5 in the form of a circular tube.

Example two:

the difference from the first embodiment is that, as shown in fig. 2, the collecting funnel 1 comprises an upper end 4 in the form of an elliptical conical shell and a lower end 5 in the form of a circular tube.

Example three:

the difference from the first embodiment is that, as shown in fig. 3 to 6, the installation convenient structure comprises an internal thread 6 arranged on the inner wall of the lower end 5 of the collection funnel 1, and the collection pipe 2 is in threaded connection with the collection funnel 1 through an external thread matched with the internal thread 6; gather funnel 1 including being conical shell form upper end 4 and lower extreme 5, lower extreme 5 includes pipe form outer wall 8, 8 bottom fixed connection ring blind hole shape cover 9 of pipe form outer wall, is equipped with the clearance 10 that is used for keeping in the saliva between ring blind hole shape cover 9 and the pipe form outer wall 8.
