Description

A kind of saliva collection and preservation container

[technical field]

The utility model relates to the technical field of medical specimen sampling equipment, in particular to a saliva collection and preservation container.

[Background technique]

Saliva is a complex mixture that contains not only various proteins, but also DNA, RNA, fatty acids, and various microorganisms. Studies have found that various protein components in blood also exist in saliva, and saliva can reflect changes in the levels of various proteins in blood. Therefore, it is possible to diagnose diseases through saliva detection. Compared with collecting blood samples, saliva collection and saliva detection are simple, convenient, safe, reliable, low-cost and non-invasive, and can be performed even at home. It can be seen that the saliva analysis technology avoids the pain of blood collection and the embarrassment of urine collection, and reduces the psychological and physical pressure of patients. In addition to this, saliva testing can greatly reduce the incidence of blood-borne diseases.

The current saliva collection method is to use cotton swabs, filter paper or disposable paper cups. These collection tools are not only difficult to seal, but also inconvenient to transport and store specimens, easily cause external contamination, and affect the results of clinical testing or scientific research. Another On the one hand, the disinfection of cotton swabs may be one of the safety hazards of sampling.

[Content of the invention]

The purpose of this utility model is to design a saliva collection and preservation container with novel structure, convenient collection and convenient sealing according to the problems of inconvenient operation and easy infection caused by using disposable plastic cups and cotton swabs as collection utensils in the existing routine inspection of saliva .

In order to achieve the above object, a saliva collection and storage container is designed, including a saliva collection tube, a saliva collection tube middle filter cover, a saliva filter core and a saliva collection tube cover. The upper end of the tube is connected to the middle filter cover of the saliva collection tube. The middle part of the middle filter cover of the saliva collection tube is provided with a groove. The saliva filter core is connected with the saliva collection tube cover on the upper part of the filter cover in the middle of the saliva collection tube.

The saliva filter is made of polytetrafluoroethylene or hydrophilic fiber material.

Compared with the prior art, the utility model has the advantages that: the multi-layer structure of the device ensures the sealing effect and is convenient for detection. The through hole enables the saliva to be filtered into the collection tube, and the saliva in the collection tube can be used for DNA detection, while the formed component of the collected saliva can be absorbed on the middle filter cover for the smear detection of oral mucosa.

[detailed description]

Below in conjunction with accompanying drawing, the utility model is further described, and the structure and principle of this device are very clear to those skilled in the art. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

As shown in Figure 1, the device includes a saliva collection tube, a middle filter cover of the saliva collection tube, a saliva filter core and a saliva collection tube cover. Cover, the middle part of the middle filter cover of the saliva collection tube is provided with a groove, the bottom of the middle filter cover of the saliva collection tube is provided with several through holes, the groove of the middle filter cover of the saliva collection tube is provided with a saliva filter core, and the upper part of the middle filter cover of the saliva collection tube Attach the cap of the saliva collection tube. The saliva filter is made of polytetrafluoroethylene or hydrophilic fiber material.

When in use, put a filter cover on the saliva collection tube, put the filter element in the filter cover, open the saliva collection tube cover, store the collected saliva in the saliva filter core, cover the collection tube cover and place the device vertically Placed, after gravity or centrifugal force, the fluid part of saliva flows into the collection tube through the through hole, the saliva in the collection tube can be used for DNA detection, and the formed component of the collected saliva can be absorbed on the middle filter cover, which is used for the coating of oral mucosa slice detection.
