FIRST EMBODIMENT

1 and 2 show a saliva collection and test card which comprises an upper cover 1 , a lower cover 2 , a sampling rod 3 and a test strip 8 arranged between the upper cover 1 and the lower cover 2 . The upper cover 1 and the lower cover 2 snap together. The top cover 1 is provided with a viewing window 12 and a sample feed port 11 . The test strip 8 comprises a display area 82 and a sample input area 81 , the viewing window 12 being assigned to the display area 82 of the test strip 8 and the sample feed opening 11 being assigned to the sample input area 81 . Furthermore, one end of the sampling stick 3 is designed as a sampling end 31 and the other end as a gripping end 32 , with a stick body 33 of the sampling stick 3 being located between the sampling end 31 and the gripping end 32 . The sampling end 31 is provided with a display portion 311 and has a saliva absorber comprising an indicator paper 4, a saliva transfer portion 5 and a sampling cotton 7 on its underside. In the present exemplary embodiment, the saliva transfer section is preferably a saliva transfer column. In this case, the indicator paper 4 is correspondingly located on the inside of the display section 311, so that a color change of the indicator paper 4 can be observed via the display section 311. One end of the saliva transfer section 5 is in close contact with the indicator paper 4 . The sampling cotton 7 is arranged below the other end of the saliva transfer portion 5 and is in contact with the saliva transfer portion 5 . A pressure plate 16 provided with a saliva inlet hole 161 is provided at the sample feed port 11 , and the sampling cotton 7 is placed in the sample feed port 11 and is in contact with the pressure plate 16 . The sampling cotton 7 is a water-absorbent cotton strip, a piece of sponge, a water-absorbent vegetable fiber or a porous polymer material. The grip end 32 of the sampling stick 3 is in the shape of a circular plate and has a diameter larger than the width of the stick body 33 .

The display section 311 is a transparent structure and is made of a transparent material, which may be plastic or glass. With the help of the sampling cotton 7, saliva is taken from a person to be tested, which is then transferred to the indicator paper 4 via the saliva transmission column in order to be able to observe a color change of the indicator paper 4 through the display section 311 and to be able to recognize from this color change whether the respective saliva collection has been completed is. The indicator paper 4 can thus be used to determine whether the sampling stick 3 was used to successfully collect saliva, in order to prevent a sampling stick 3 without saliva or with an insufficient amount of saliva being inserted into the sample feed opening 11 as a result of human error. In the present embodiment, a blue indicator paper 4 is preferably used as the indicator paper 4, and a sufficient amount of saliva has been collected when the saliva transferred to the indicator paper 4 via the saliva transfer portion 5 causes the indicator paper to change color to blue.

As can be seen from FIG. 6, a single test strip 8 is present in the present exemplary embodiment. A latching groove 21 is formed on the lower cover 2, into which the test strip 8 can latch in order to prevent the test strip 8 from being displaced during the respective test process. On both sides of that point on the lower cover 2 where the sample input area 81 of the test strip 8 is to be arranged, there is an additional excess saliva collection channel 22, in which the excess saliva squeezed out of the sampling cotton 7 and therefore flowing over the test strip 8 can be collected in order to avoid the test accuracy of the test strip 8 being affected by pressing too quickly or by an excessive amount of saliva.

As shown in FIG 7, the sampling end 31 of the sampling rod 3 comprises a top wall 313 and a plurality of side walls 312, the side walls 312 being arranged perpendicularly or at an angle to the top wall 313 in such a way that the inner side surfaces of the side walls 312 are each connected to the inner Side surface of the top wall 313 include an angle of 0 ° to 180 °. The indicator paper 4 and the saliva transfer section 5 are located in a sampling basin enclosed by the top wall 313 and the side walls 312 , while the sampling wadding 7 adheres to the inside of the top wall 313 . The sampling end 31 includes a single top wall 313 and four side walls 312. On the outside of at least one of the side walls 312, a retaining rim 316 is provided. When the sampling end 31 is arranged in the sample feed opening 11, the retaining edge 316 located on the respective side wall 312 of the sampling end 31 adjoins the inside of a side frame 14 of the upper cover 1 provided on the sample feed opening 11 in order to close the sample feed opening 11 together with the top wall 313 and thus preventing saliva from spraying out of the sample feed opening 11 . In the present embodiment, the retaining edge 316 is arranged on the side wall 312 facing the handle end 32 and is located at the connection point between this side wall 312 and the top wall 313, while the other side walls 312 each have their outside against the inside of the sample feed opening 11 provided Side frame 14 of the top cover 1 adjoin. If the retaining edge 316 is located at the connection point between the top wall 313 and a side wall 312, the retaining edge 316 is formed by an extension of the respective edge of the top wall 313 in the horizontal direction outwards, over the connection point between the top wall 313 and the side wall 312 beyond protruding edge structure.

The retaining rim 316 has a horizontally extending width of 0.2 to 0.5 mm. In the present embodiment, the width of the retaining edge 316 in the horizontal direction is preferably 0.3 mm.

It can be seen from FIGS. 7 and 8 that the top wall 313 is provided with a transmission hole 314 for passing through the indicator paper 4 and the saliva transmission section 5, the U transmission hole 314 communicating with the display section 311. The display section 311 results from the fact that the upper wall 313 protrudes upwards in sections. The display section 311 is provided with an inner space for accommodating the indicator paper 4 communicating with the U transmission hole 314 . Between the sampling wadding 7 and the sampling end 31 there is a saliva separating layer 6, via which the sampling wadding 7 is glued below the sampling end 31 to the latter.

The saliva separating layer 6 is in contact with the inner layer of the upper wall 313 of the sampling end 31 on one side and with the sampling wadding 7 on the other side. In the saliva separation layer 6, a through hole 61 for passing the saliva transfer portion 5 is formed. The through-hole 61 is positioned corresponding to the transmission hole 314 so that the saliva transmission column can pass through the through-hole 61 and the U-transmission hole 314 in order and thereafter contact the indicator paper 4 . Since the saliva can only be transferred from the sampling cotton 7 via the saliva transfer section 5 to the indicator paper 4 when there is a sufficient amount of saliva on the sampling cotton 7, in order to then determine using the indicator paper 4 whether a sufficient quantity of saliva has been collected, the saliva separating layer 6 provided in order to ensure, on the one hand, that a sufficient amount of saliva is removed by means of the sampling wadding 7 and that saliva adheres uniformly to the sampling wadding 7 . On the other hand, direct contact between the sampling cotton 7 and the indicator paper 4 should be prevented, which would cause a color change in the indicator paper 4 even if an insufficient amount of saliva was collected with the sampling cotton 7, which in turn would lead to an incorrect assessment by the respective sample collector would lead. The saliva separating layer 6 therefore not only creates a connection between the sampling wadding 7 and the sampling end 31 of the sampling stick 3, but also a more precise sampling via the indicator paper

4 can be implemented in order to be able to determine in a simple manner whether a satisfactory saliva collection is taking place.

The saliva separating layer 6 has an area equal to or greater than the area of the upper surface of the sampling cotton 7 to ensure that the sampling cotton 7 and the indicator paper 4 are completely separated by the saliva separating layer 6 from each other. The saliva separating layer 6 is a double-sided adhesive material that creates an adhesive connection between the sampling wadding 7 and the inside of the top wall 313 of the sampling end 31 .

As FIG 3 and 4 show, a latching block 315 is provided on the outside of one end of the sampling end 31 . A side frame 14 is arranged on both sides of the sample feed opening 11 of the upper lid 1, respectively. Furthermore, a stopper plate 15 is provided at one end of the sample injection port 11 and a locking piece 13 at the other end of the sample injection port 11, both ends of the stopper plate 15 being connected to the side frames 14 on both sides. Thus, the sample injection port 11 is located in an area enclosed by the side frames 14 and the stopper plate 15 . Also formed in the side frame 14 or the stopper plate 15 is a locking hole 151 into which the locking block 315 can lock. The locking piece 13 is used for locking with the rod body 33 located between the sampling end 31 and the handle end 32. The side frames 14 and the stop plate 15 allow the sampling end 31 of the sampling rod 3 described above to be tightly received in the sample feed opening 11, which allows the saliva sample to flow out in the respective printing process in the environment can be excluded.

In the present exemplary embodiment, it is preferably provided that the latching block 315 is arranged on the outside of the side wall 312 facing away from the handle end 32 and the latching hole 151 is arranged in the stop plate 15, with the latching block 315 being in a number of one and the latching hole 151 correspondingly also provided in a quantity of one. By engaging the locking block 315 in the locking hole 151 , the sampling end 31 of the sampling rod 3 is locked in the sample feed opening 11 . The locking block 315 has its upper end surface flush with the top wall 313 of the sampling end 31 and has a lower height than the respective side wall 312 in order to thereby facilitate the locking of the locking block 315 into the locking hole 151 .

The locking block 315 has a lower height than the locking hole 151, which means that when the sampling rod 3 is pressed down in the sample feed opening 11, it can be ensured that when the sampling cotton 7 is pressed down by means of an external force exerted by the handle end 32, there is enough space for the movement of the Locking blocks 315 and the sampling cotton 7 is available down. At the same time, the locking block 315 is prevented from jamming in the locking hole 151, which would result in the sampling end 31 not being able to be pressed down.

As can be seen from FIG. 5, a plurality of saliva inlet holes 161 and a plurality of ribs 162 are formed on the pressure plate 16 of the upper cover 1 , the saliva inlet holes 161 being located above the sample input area 81 of the test strip 8 . The ribs 162 are distributed symmetrically on either side of the saliva inlet holes 161 . One saliva inlet hole or two or more than two saliva inlet holes 161 is/are provided. By providing two or more than two saliva inlet holes 161, a rapid flow of saliva from the sampling cotton 7 onto the test strips 8 can be ensured. The saliva inlet holes 161 may be spaced from each other along the length direction of the test strip 8, i.e., one or more saliva inlet holes 161 are provided above the sample input portion 81 of each test strip 8.

The ribs 162 may be arranged along the length direction of the test strip 8. The ribs 162 are an anti-splash rib structure. When the sampling wadding 7 comes into full contact with the ribs 162 on the pressure plate 16, the saliva contained in the sampling wadding 7 can pass through the underside of the sample more easily and more evenly.

To do this, the patient holds the sampling end 31 in his mouth to collect saliva with the sampling cotton 7 made of a water-absorbent cotton strip. After a sufficient saliva content has been reached, the locking block 315 on the sampling end 31 is inserted into the locking hole 151 for locking with it, at the same time the locking piece 13 is firmly connected to the rod body 33 of the sampling end 31 and the handle end 32 is pressed firmly down until the rod body 33 firmly snaps into the locking piece 13 in order to achieve complete contact of the sampling cotton 7 with the pressure plate 16 at the sample feed opening 11. Through the cooperation between the grip end 32 and the ribs 162 on the pressure plate 16, the saliva is pushed out evenly from the sampling cotton 7 and flows through the saliva inlet hole(s) 161 onto the sample input portion 81 of the test strip to realize a full contact reaction. Thereafter, a corresponding result displayed by the display area 82 of the test strip 8 is read through the viewing window 12 within a predetermined time. In this way, a saliva collection and a saliva test are carried out at the same time.
