Problems solved by technology

In addition, there is no suggestion of a method of collecting while promoting the secretion of saliva while killing bacteria in the oral cavity, or a small and simple device that can be recovered after collection.
In particular, there has not been seen any simple device that realizes micro-collection in a very short time for POCT use, and can be recovered immediately while specifically decomposing substances that inhibit the measurement of saliva intrinsic properties.

Embodiment 1

[0042] Example 1 Saliva collection device and saliva slurry component recovery device

[0043] An example of the saliva collection device and saliva slurry component recovery device of this embodiment is shown in FIG. 1.

[0044] The swab-type saliva collecting device 1 is formed with a saliva absorber 2 made of cotton with antibacterial component chitin / chitosan on the surface, a gasket 4 made of paper and a pressing pad 5 similar to the piston rod 3 as a paper shaft. . Moreover, the saliva absorber is 65mm 3 The volume is made into a cone shape.

[0045] The syringe-type saliva slurry recovery device 6 is molded from polyethylene, and the internal volume of the squeezing section 8 is set to 20 mm 3 Cone shape, 1mm is placed on the way from the press section 8 to the recovery hole 7 3 The above-mentioned cotton as a filter layer. In addition, the recovery hole diameter is set to 1 mm or less to prevent the cotton from falling off during the recovery of the saliva slurry component...

Embodiment 2

[0046] Example 2 Saliva collection and recovery kit

[0047] An example of the saliva collection and recovery kit and method of use of this embodiment is shown in figure 2 in.

[0048] 0.05wt% cetylpyridinium chloride (manufactured by Takeda Pharmaceutical Co., Ltd.) as a bactericidal ingredient, sweeteners, sours, and flavors (manufactured by POLAFOODS Co., Ltd.) as saliva secretion promoting ingredients are blended to form a The sweet and sour solution is set as the sterilizing mouthwash 10 containing salivary secretion components.

[0049] To the above-mentioned blended solution, carboxymethyl cellulose (manufactured by Daiichi Kogyo Pharmaceutical Co., Ltd.) was added, and a non-woven fabric containing chitin / chitosan as an antibacterial component (80g / m 2 ) (Manufactured by OMIKENSHI Co., Ltd.), dried, and used as the sublingual moisture absorber 11.

[0050] The saliva collecting device 1 is used as the saliva collecting device 1 after spraying the above-mentioned blended li...

Abstract

A method of the collection of saliva for examining saliva such as quantifying glucose in the saliva, characterized in that sterilization in the oral cavity, promotion of saliva secretion and collection of a minor amount of the saliva are performed at the same time thereby. A syringe-type instrument for collecting and recovering saliva with the use of a less expensive member for recovering salivary serum components while eliminating viscous components in the saliva; and a method of collecting saliva and recovering the salivary serum components using the instrument.

Description

Technical field [0001] The present invention relates to a disposable simple instrument and a use for the purpose of using saliva from various salivary glands such as the parotid gland, submandibular gland, and sublingual gland as a test sample in saliva detection, which can be implemented in saliva collection and recovery. Their saliva collection and recovery methods. Background technique [0002] Previously, the inventors of the present invention designed an oral secretion fluid collection method and a film-type collection and recovery device for quantification of glucose in saliva (for example, WO02 / 086453 (2002)), and explained that the oral cavity suppresses the decomposition of glucose by bacteria. The bactericidal effect of internal bacteria (WO02 / 31105 (2002)), and clarified the simple collection and recovery method of saliva, and the usefulness of saliva as a diagnostic material. [0003] At present, in the saliva test (Annals of the New York Academy of Sciences, Vol.694,...
