Cartridge 101 is generally lid-shaped having an annular end wall and a peripheral wall circumferentially connected to the outer periphery of the end wall. The sampling body 200 is partially received and secured within the internal cavity of cartridge 101.
The connection of the sample body 200 to the cartridge 101 is, for example, by adhesive-on-demand. Preferably, the sampling body 200 is made of a fiber having a strong water absorption property and is compressed into a cylindrical shape. The axial length of sampling body 200 is greater than the axial length of cartridge 101 such that sampling body 200 is extended from cartridge 101 in its native state (i.e., when the sampling assembly is not assembled into test receptacle 300), and a subject is able to place the extended end of sampling body 200 in the mouth for saliva collection. The sample volume taken after the saliva sample has been sufficiently absorbed by the sample volume 200 is sufficient to provide two tests.
The indicator barrel 102 has a hollow interior cavity and the interior cavity of the indicator barrel 102 and the interior cavity of the cartridge 101 are in communication. Indicator piece 600 is received within the lumen of indicator barrel 102 and contacts sample volume 200.
The indicator 600 is made of a material including a water-absorbent material, for example, the indicator 600 is a color-changing indicator paper having a color different before and after absorbing water. When a sufficient amount of the saliva sample has been absorbed by the sample body 200, the saliva is further transmitted to and absorbed by the indicator 600, and the indicator 600 changes color.
Preferably, the indicator barrel 102 is transparent or has at least a partially transparent region so that an operator can identify the color of the indicator 600 through the indicator barrel 102.
The outer peripheral wall of the locking barrel 103 has a locking structure for coupling with a locking structure of an inner peripheral wall of the detection container 300 to be described later, thereby achieving detachable connection of the sampling handle 100 and the detection container 300. Preferably, the locking structure of the outer peripheral wall of the locking cylinder 103 and the locking structure of the inner peripheral wall of the detection container 300 are both screw structures.
The outer diameter of the peripheral wall of the hand-held cylinder 104 is larger than the outer diameter of the peripheral wall of the lock cylinder 103. When the sampling handle 100 is mounted to the test receptacle 300, the locking barrel 103 will be received within the interior cavity of the test receptacle 300 while the hand-held barrel 104 exposes the test receptacle 300 to facilitate removal of the sampling handle 100.
A sealing ring S is mounted on the outer periphery of the locking cylinder 103 and abuts against the end of the hand-held cylinder 104, and when the sampling handle 100 is mounted on the inspection container 300, the sealing ring S can simultaneously perform a sealing function in the axial direction a and the circumferential direction.

The internal diameter of the reservoir 301 is smaller than the external diameter of the sample body 200. Preferably, the outer diameter of the reservoir 301 is also smaller than the outer diameter of the sample body 200. So that the sampling body 200 will be compressed in the axial direction a by the cartridge 301 during the sampling process described below.
A sealing membrane 500 is fixed to the bottom wall 302 to close the opening of one end of the reservoir 301 at the axial end of the detection vessel 300. The sealing membrane 500 is, for example, an aluminum sealing membrane, which may be attached to the detection vessel 300, for example, using a heat sealing process.
The test paper stopper 400 is in the shape of a cylinder with openings at both ends. Preferably, the test paper plug 400 can be placed in the test receptacle 300 in close contact with the inner wall of the test receptacle 300. The inner diameter of the test card plug 400 is equal to or slightly larger than the outer diameter of the sampling cartridge 101, and the inner diameter of the test card plug 400 is larger than the outer diameter of the reservoir 301, so that after the sampling body 200 is squeezed and deformed to release part of the saliva sample, the saliva sample can flow into the detection cavity 301N.
The outer peripheral wall of the test paper plug 400 defines a plurality of test paper slots 401 for storing test paper. The main body of the test paper jam 400 is provided with a plurality of support portions 402 axially protruding from one axial end thereof, in other words, one end of the test paper jam 400 is not flush in the axial direction. Placing the test card plug 400 inside the detection container 300 with the support 402 facing inwards, the support 402 will abut against the bottom end face of the detection chamber 301N, while the detection chamber 301N has areas in the circumferential direction that are not filled by the test card plug 400, which areas provide a flow space for the saliva sample.
Next, a method of sampling and retesting a fluid using a saliva collection device according to the present invention will be described.
The subject first takes a saliva sample using the sampling assembly and inserts sampling handle 100 into test receptacle 300 with test paper plug 400 after indicator 600 changes color to indicate that the sample size is sufficient. After the sampling handle 100 is completely mounted on the detection container 300, that is, after the external thread of the locking cylinder 103 is completely screwed with the internal thread of the detection container 300, the sampling body 200 is pressed by the liquid storage cylinder 301, a part of the saliva sample flows into the liquid storage cavity 301M to be temporarily stored, and a part of the saliva sample flows into the detection cavity 301N and further contacts the detection test paper in the test paper card plug 400, so that the first detection is obtained.
When the saliva sample stored in the liquid storage cavity 301M needs to be rechecked, the sealing film 500 can be punctured, so that the saliva sample in the liquid storage cavity 301M flows out.
