Description

Oral cavity biological sample dry-type collecting tool

Technical Field

The utility model relates to an oral cavity biological sample dry-type collecting tool.

Background

The clinical method of taking biological samples from the oral cavity up to now is to use a cotton swab to wipe the inside of the oral cavity and then to keep the sample on the cotton swab for laboratory tests, which may take too much saliva because the cotton swab stays in the oral cavity too long, and dilute the concentration of the sample extraction reagent, thereby increasing the reagent consumption. At the same time, it also generally requires the involvement of medical personnel, consuming their time and effort, increasing the chance of cross-infection. In addition, the collected sample is limited to the oral cavity, and the deep lung sample cannot be collected, so that more pathogens can be missed to generate false negative.

Respiratory diseases generally have oral odors before symptoms are present at the beginning of the disease, and the odors are smelled by surrounding people to cause the people to generate the same odors, which is infection. Based on this phenomenon, the inventors have recognized that the collection of the blown-out breath can be used as a method for collecting disease samples.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

See fig. 1-9.

The first embodiment is as follows:

an oral biological sample dry collecting tool comprises a base with an inner cavity 1; the base is provided with an air inlet 2; an oral cavity biological sample collecting block 3 is fixed in the inner cavity 1 of the base.

Specifically, the oral biological sample collection block 3 is a wet filter paper wetted with a buffer solution (the filter paper may be a glass fiber filter paper, but may be a common filter paper).

Specifically, the base is a tube group; the pipe group comprises an upper pipe body 4 and a lower pipe body 5; the lower end of the upper pipe body 4 is detachably connected with the lower pipe body 5 (more specifically, the lower end of the upper pipe body 4 is connected with the lower pipe body 5 through a bolt); the oral biological sample collecting block 3 is fixed in the lower tube body 5; the air inlet 2 is positioned at the upper end of the upper pipe body 4.

Specifically, the lower end of the lower tube body 5 is provided with a first air outlet 6.

Specifically, a tray 9 is connected in the lower pipe body 5; the oral biological sample collecting block 3 is fixed above the tray 9; the tray 9 is provided with a vent hole 10.

Specifically, the lower end of the lower pipe body 5 is detachably connected with a lower cover 7; the upper end of the upper pipe body 4 is detachably connected with an upper cover 8; more specifically, the lower end of the lower pipe 5 is screwed to the lower cap 7, and the upper end of the upper pipe 4 is screwed to the upper cap 8.

In the first embodiment, when the tube set is used, the upper cover 8 and the lower cover 7 are opened, air is blown into the inner cavity 1 of the tube set, after the air is blown for a plurality of times, the upper cover 8 and the lower cover 7 are covered, the tube set is labeled, and the sample collection is finished, so that the tube set is very convenient. When the detection is needed, the upper tube body 4 and the lower tube body 5 are only required to be unscrewed, and the sample on the oral biological sample collection block 3 can be conveniently detected.
