(stock solution component)

Referring first to fig. 1, 2 and 6, the basic structure of the reservoir assembly will be described.

The reservoir handle 100 acts as a stand in the reservoir assembly for holding the reservoir 500. The liquid storage handle 100 includes a chuck 101, a connecting cylinder 102, and a fixed cylinder 103, which are connected in this order in the axial direction a.

The chuck 101 is annular with a central through hole leading to the inner cavity of the connecting cylinder 102 for the passage of a snap 900 to be described later in the disassembly and assembly. The outer periphery of the cartridge 101 has two radially symmetrical notches 1011 for providing axial retention for the cartridge 101 when the reservoir handle 100 is mounted to the sampling handle 200, as described further below.

The indicator 700 is made of a material including a water-absorbent material, and for example, the indicator 700 is a color-changing indicator paper having a color different before and after absorbing water. When a sufficient amount of the saliva sample is absorbed by the reservoir 500, the saliva is further transferred to and absorbed by the indicator 700, and the indicator 700 changes color. Preferably, the indicator 700 is circumferentially coated at one axial end of the reservoir 500.

Preferably, one end of the reservoir 500 to which the indicator 700 is attached is fixed to the reservoir fixing ring 103 by means of spot gluing.

(sampling component)

Referring next to fig. 1-4, the basic structure of the sampling assembly will be described.

The sampling handle 200 acts as a stand in the sampling assembly for holding the sampling body 600, the second sealing ring S2, and the reservoir assembly.

The sampling handle 200 is a hollow cylinder, and includes a first cylinder 201, a second cylinder 202, a third cylinder 203, a locking cylinder 204 and a handheld cylinder 205, which have communicated inner cavities, in sequence in the axial direction a.

The first cartridge 201 is generally cap-shaped with an internal cavity for receiving a sample volume 600. The sampling body 600 is extended from the first cartridge 201 in a natural state, i.e. when the sampling assembly is not assembled into the test receptacle 300, the axial length of the sampling body 600 is greater than the axial length of the first cartridge 201, and a subject can place the extended end of the sampling body 600 in the mouth to collect saliva.

The interior cavity of the second cartridge 202 is for receiving the liquid storage body 500. The inner diameter of the second cartridge 202 is smaller than the inner diameter of the first cartridge 201, which enables the sample body 600 to be retained and retained in the axial direction a by the end of the first cartridge 201, as will be more readily understood when the sample body 600 is deformed by axial compression as described below.

The third cylinder 203 is configured to receive the stationary cylinder 103 and to mate with it to form an end seal, for example, the third cylinder 203 has an inner diameter slightly smaller than the outer diameter of the first seal ring S1, such that the first seal ring S1 sealingly fills the radial gap between the stationary cylinder 103 and the third cylinder 203. The third cylinder 203 has an inner diameter larger than that of the second cylinder 202.

The outer peripheral wall of the locking barrel 204 has a locking structure for coupling with a locking structure of an inner peripheral wall of the detection vessel 300 to be described later, thereby enabling a detachable connection of the sampling handle 200 and the detection vessel 300. Preferably, the locking structure of the outer peripheral wall of the locking cylinder 204 and the locking structure of the inner peripheral wall of the detection container 300 are both screw structures.

Preferably, a positioning portion 2041 which is symmetrical in the radial direction and protrudes downward is provided at the root portion of the lock cylinder 204, that is, an end surface of the lock cylinder 204 close to the third cylinder 203. The positioning portion 2041 is used for abutting against an axial end of a test paper jam 400 to be described below, so that the sampling handle 200 and the test paper jam 400 are tightly fitted in the detection container 300.

The inner diameter of the peripheral wall of the hand-held cylinder 205 is larger than the inner diameter of the peripheral wall of the lock cylinder 204. Forming a ring-like stop wall 2052 connecting the hand-held cartridge 205 and the locking cartridge 204. In one aspect, the second sealing ring S2 may be sleeved around the periphery of the locking cylinder 204 and abut against the stop wall 2052 to achieve a limit in the axial direction a. On the other hand, the stop wall 2052 acts to limit the position of the chuck 101 of the cartridge handle 100 in the axial direction A when the cartridge handle 100 is attached to the sampling handle 200, as will be further described below when describing the assembled relationship of the cartridge handle 100 and the sampling handle 200. In addition, when the sampling handle 200 is attached to the test receptacle 300, the locking barrel 204 will be received within the interior of the test receptacle 300 and the hand-held barrel 205 will be exposed from the test receptacle 300 to facilitate removal of the sampling handle 200.

When the sampling assembly is assembled, the reservoir assembly extends into the sampling handle 200 from the top of the sampling handle 200, the notch 1011 is circumferentially aligned with the stop strip 2051, and the cartridge 101 enters the interior cavity of the hand-held barrel 205 and the cartridge 101 abuts against the stop wall 2052. Preferably, the distance from the end face of the stopper strip 2051 located below D to the end face of the stopper wall 2052 located above is equal to the thickness of the chuck 101 in the axial direction a. The chuck is then rotated circumferentially to circumferentially offset the notches 1011 and the bars 2051 so that the notches 1011 and the bars 2051 position the chuck 101 on opposite sides of the axial direction a.

During the installation process (or removal process as will be described below) of the sampling handle 200 and the reservoir handle 100, the reservoir handle 100 can be manipulated by the clasp 900. Referring to fig. 4, the clip 900 includes a cylindrical base 901 and two radially symmetrical legs 902 connected to the base 901 and extending in the axial direction. The end of the leg 902 remote from the base 901 has a hook 9021 projecting radially outward. Preferably, the end faces of the two leg portions 902 located at the outer periphery (excluding the hook portions 9021) are coplanar with the outer peripheral face of the base portion 901, while the outer diameter of the base portion 901 (excluding the ridge portions 9011) is equal to the inner diameter of the connecting cylinder 102, and the radial distance between the outer peripheral faces of the two hook portions 9021 is greater than the inner diameter of the connecting cylinder 102. Preferably, the outer peripheral wall of the base 901 has a plurality of circumferentially distributed ridges extending in the axial direction, so as to form a ridge 9011, and the surface of the ridge 9011 is uneven and has a high friction coefficient, so that the gripping of the ridge 9011 to operate the buckle 900 to rotate circumferentially is easier.

The clip 900 is inserted into the cavity of the connector barrel 102 with the leg 902 facing inward, and at this time, the two hooks 9021 are pressed by the inner wall of the connector barrel 102 to be close to each other, so that the two legs 902 are elastically deformed radially inward. When the hook 9021 is inserted into the bayonet 1021 in circumferential alignment, the leg 902 returns to its original shape or at least reduces its deformation outward in the radial direction, and the hook 9021 is at least partially received in the bayonet 1021 to position the clip 900 in the connector barrel 102. When the clip 900 is removed, the hook 9021 is urged radially inward from the bayonet 1021, so that the hook 9021 enters the radially inward side of the inner wall of the connecting cylinder 102, and the ridge 9011 is gripped to axially remove the clip 900 from the connecting cylinder 102.

After the liquid storage assembly and the sampling handle 200 are assembled, the liquid storage body 500 contacts the sampling body 600, so that saliva absorbed by the sampling body 600 can be transmitted to the liquid storage body 500 to be stored.

After the reservoir assembly is assembled to the sampling handle 200, the sealing membrane 800 is sealingly attached to the axial end of the hand-held barrel 205. The sealing film 800 is, for example, a foil paper which is easily torn. When it is desired to use a saliva sample stored in the reservoir 500, the operator may tear the sealing membrane 800 and remove the reservoir assembly from the sampling handle 200 via the clasp 900.

It should be understood that clasp 900 may not be configured in a kit for a saliva collection device, e.g., clasp 900 is only provided to the assembler before shipment of the device and the operator at the time of review, and clasp 900 may be reusable. It is then difficult for others to remove the reservoir assembly from the sampling handle 200 without the aid of other tools, which helps control the quality of the testing process.
