Double tube saliva sampler

Abstract

The invention discloses a two-pipe saliva sampling device. When the sampling device is used for sampling, inner threads (6) on an outer ring (1) are matched with outer threads (8) on an opening end of a centrifugal pipe (5), an inner plug (3) is positioned in the outer ring (1), the lower part of a silicone pipe (4) is connected with the inner plug (3) into a whole, the upper part of the silicone pipe (4) penetrates out of the outer ring (1), and filling fibers (9) are arranged in the silicone pipe (4); when the sampling device is used for storage, the inner threads (6) on the outer ring (1) are matched with outer threads (8) on the opening end of the centrifugal pipe (5), a washer (2) is positioned on the topmost end in the outer ring, the inner plug (3) is arranged below the washer, the silicone pipe (4) is connected with the inner plug into a whole, the lower part of the silicone pipe (4) penetrates out of the outer ring to be arranged in the centrifugal pipe (5), and the filling fibers (9) are arranged in the silicone pipe. By adopting the two-pipe saliva sampling device, the saliva sampling process is simplified, the discomfort in the sampling process is eliminated, the saliva sampling amount is increased, the sampling process is safe and sanitary, and the two-pipe saliva sampling device is particularly applicable to babies or tested crowds having diseases and being difficult to sample.

Description

technical field [0001] The invention relates to a double-pipe saliva sampler, which belongs to the technical field of biochemical analysis and detection equipment. Background technique [0002] In recent years, saliva, as a non-invasive testing sample, has received attention in many fields such as disease diagnosis, psychological monitoring, and sports medicine. The components in saliva often have a good correspondence with blood. Saliva samples have the advantages of non-invasiveness and easy sampling, and are easily accepted by the subjects. However, the concentration of target components in saliva is often significantly lower than that in blood, so saliva collection must be sufficient to meet the needs of instrument detection (usually on the order of milliliters). Most of the current saliva collection methods still allow the subjects to spit out a sufficient amount of saliva directly in an appropriate container or use a sampling stick or a sampling strip made of filter p...

Problems solved by technology

Among them, CN201852719U and CN102032998A are mainly designed for the analysis of genes in saliva, and the sampling volume is relatively small; CN1703615A better solves the problems of sampling volume, hygiene and safety, etc., but the disadvantage is that the device is too large, which is not convenient for sampling large sample populations; CN200948144Y is mainly used for the diagnosis of oral diseases, so the sampling volume is not enough to detect some components in saliva

Existing patents can solve certain saliva collection problems, but there is no special design for the saliva collection process of infant subjects, which fails to alleviate the discomfort of children during the sampling process, and sampling will occur in actual sampling and analysis Insufficient volume and low sample quality, and the patented design does not take into account the pretreatment of saliva samples, so it is not convenient to use
