The collecting part 122 is used for collecting the sample 2, and specifically, the collecting part 122 is configured to be a spoon-shaped structure so as to facilitate collection of the sample 2. When the collecting element 12 slides along the tube 111 in the first direction under the action of external force, the collecting portion 122 can pierce the sealing portion 112 and extend from the second cavity 114 into the first cavity 113.

In actual operation, the collecting element 12 is first separated from the detecting element 11, and the user holds the operation portion 121 of the collecting element 12 and operates the collecting portion 122 to collect the sample 2. Then, the collecting element 12 is inserted into the tube 111 from the opening of the tube 111, and the operation portion 121 is tightly attached to the opening of the tube 111. Further, the user operates the collecting member 12 to slide in a first direction (as indicated by arrow a in fig. 2), during which the collecting portion 122 pierces the sealing portion 112 and the second chamber 114 extends into the first chamber 113 to contact the diluent.

In addition, the controller controls the detecting element 11 to obtain the reaction result between the test strip 20 and the sample 2 solution, and displays the reaction result on the display screen.

The test strip 20 is held in the second chamber 114 in a first orientation. Optionally, the test strip 20 may be one kind, or may be plural kinds. Different types of strips 20 differ in their chemical composition and different sample 2 parameters can be detected using different strips 20.

The tube 111 includes a first sub-tube 1111 with an open end and a closed end, and a second sub-tube 1112 with open ends, wherein one end of the second sub-tube 1112 extends into the first sub-tube 1111 and is closely attached to the first sub-tube 1111, and the sealing portion 112 is located in the first sub-tube 1111 and seals the open end of the second sub-tube 1112. The first sub-tube 1111 and the sealing portion 112 define a first chamber 113, and the second sub-tube 1112 and the sealing portion 112 define a second chamber 114.

Specifically, the size of the opening of the first sub-tube 1111 is consistent with the size of the outer diameter of the second sub-tube 1112. One end of the second sub-pipe 1112 extends into the first sub-pipe 1111 through the opening of the first sub-pipe 1111, and is closely connected with the first sub-pipe 1111. The other end opening of the second sub-pipe 1112 is located outside the first sub-pipe 1111 and is configured to form an opening of the pipe body 111. The sealing portion 112 may be a sealing film, a sealing sheet, etc., and the sealing portion 112 is used for sealing the diluent in the first sub-cavity. By providing the first sub-pipe 1111 and the second sub-pipe 1112, when the first sub-pipe 1111 and the second sub-pipe 1112 are detached, the diluent can be conveniently injected into the first sub-pipe 1111 from the opening of the first sub-pipe 1111. When the second sub-pipe 1112 is fitted to the first sub-pipe 1111, the diluent may be sealed to prevent leakage of the diluent.

Referring to fig. 3 again, further, an annular partition plate 1113 is protruded and configured on the inner wall of the second sub-tube 1112, the partition plate 1113 partitions the second sub-cavity into a detection cavity 1142 and a mixing cavity 1144 located between the detection cavity 1142 and the first sub-cavity, the detection cavity 1142 is communicated with an opening at the other end of the second sub-tube 1112 and is used for accommodating the test strip 20, and the mixing cavity 1144 is communicated with the detection cavity 1142 through a central hole of the partition plate 1113.

In actual operation, after the sample 2 is collected by the collecting element 12, the collecting element 12 is inserted into the second sub-pipe 1112 from the opening at the other end of the second sub-pipe 1112. During the sliding of the collecting member 12 in the first direction, the collecting portion 122 passes through the detecting chamber 1142 and the mixing chamber 1144 in sequence until the sealing portion 112 is pierced and the first chamber 113 is inserted. The setting of division board 1113 can be with second chamber 114 separation and carry out functional regional division, and at the in-process that sample collection detection device 10 rocked, division board 1113 can also obstruct certain sample 2 liquid to prevent to mix uneven sample 2 liquid and test paper strip 20 contact.

Further, the acquisition member 12 further comprises a blocking portion 124, the blocking portion 124 being coupled to the handle 123 and positioned within the detection chamber 1142. When collecting part 122 pierces sealing part 112, blocking part 124 blocks the center hole of partition plate 1113. Because the centre bore of division plate 1113 is blocked, then in the in-process of rocking sample collection detection device 10, sample 2 and diluent can seal and mix in first chamber 113 and mixing chamber 1144 to and prevent to mix uneven sample 2 liquid and the contact of test paper strip 20 and lead to the condition emergence that detects inaccurately.

Referring to fig. 4 and 5, further, collecting element 12 further includes a filter portion 125, and filter portion 125 is coupled to handle 123 and located in mixing chamber 1144. The collection member 12 can slide in a second direction (the direction indicated by the arrow b in fig. 2) opposite to the first direction with respect to the tube 111 under the external force until the filter portion 125 covers the central hole of the partition plate 1113.

When the sample collection and detection device 10 is tilted or caused to tilt, the mixed sample 2 liquid flows into the detection cavity 1142 from the mixing cavity 1144 through the filter 125, and contacts and reacts with the test strip 20. The filter part 125 can filter the large-particle sample 2 and prevent the large-particle sample 2 from contacting the test strip 20, so that the sample collection and detection device 10 has excellent detection accuracy.

In the process of mixing and filtering, the operation part 121 is always tightly closed to the opening at the other end of the second sub-tube 1112, so that the sample 2 liquid can be prevented from splashing to the outside of the sample collection and detection device 10 to pollute the external environment.

Alternatively, the outer diameters of the filter portion 125 and the stopper portion 124 may coincide with the pore diameter of the central hole. Preferably, the outer diameters of the filter part 125 and the blocking part 124 are larger than the hole diameter of the central hole of the partition plate 1113. When collecting member 12 slides in the first direction until blocking portion 124 abuts on the side of partition plate 1113 opposite to mixing chamber 1144, blocking portion 124 blocks the central hole of partition plate 1113; when the acquisition member 12 is slid in the second direction until the blocking portion 124 abuts against the side of the separation plate 1113 facing the mixing chamber 1144, the filter portion 125 covers the central hole of the separation plate 1113. Therefore, a user can judge whether the movement of the collecting element 12 along the first direction is in place or not by judging whether the blocking part 124 abuts against the partition plate 1113 or not, and can judge whether the movement of the collecting element 12 along the second direction is in place or not by judging whether the filter part 125 abuts against the partition plate 1113 or not, so that the convenience of the operation of the collecting element 12 is improved.

It should be noted that, during the sliding of the collecting member 12 along the first direction, in order to ensure that the filter 125 can pass through the central hole of the partition plate 1113 and enter the mixing chamber 1144, the filter 125 may be an elastic filter screen. The filter portion 125 can pass through the central hole of the separation plate 1113 and move into the mixing chamber 1144 by deformation.

Furthermore, the filter portion 125 and the blocking portion 124 are both annular structures, and the handle portion 123 is disposed through the central holes of the filter portion 125 and the blocking portion 124 along the first direction and is clamped with the filter portion 125 and the blocking portion 124. Thus, the reliability of assembly of the acquisition part 12 can be effectively improved.

In one embodiment, at least the second sub-tube 1112 of the first sub-tube 1111 and the second sub-tube 1112 is a transparent tube. After a certain period of reaction, the color of the test strip 20 can be observed through the sidewall of the second sub-tube 1112, and the health condition of the user can be determined by the color. In such an embodiment, the test strip 20 does not need to be taken out during the determination of the result, and thus the operation is simple.

Further, the first sub-tube 1111 may be also a transparent tube, so that it is possible to observe whether the collecting part 122 pierces the sealing part 112 through the first sub-tube 1111 and the second sub-tube 1112 during the sliding of the collecting member 12 in the first direction.

Of course, in other embodiments, both the first sub-tube 1111 and the second sub-tube 1112 may be opaque tubes. After the reaction is completed, the collecting member 12 can be detached, and the test strip 20 can be taken out. By observing the color of the test strip 20, the health status of the user can be determined.

In the sample collection and detection system 1 and the sample collection and detection device 10 thereof, during operation, the operation portion 121 of the collection member 12 is tightly sealed to the opening of the tube 111, and during the process that the collection member 12 slides along the first direction relative to the tube 111 under the action of external force, the collection portion 122 can pierce the sealing portion 112 and extend into the first cavity 113 from the second cavity 114, so that the sample 2 on the collection portion 122 can be mixed with the diluent in the first cavity 113. Then, rock sample collection detecting system 1, sample 2 forms sample 2 liquid with the mixing of diluent, and then, inclines or inverts sample collection detecting device 10 to make things convenient for sample 2 liquid can contact and react with test paper strip 20, a period of time later, can obtain sample 2 liquid and test paper strip 20's reaction result. And whether the user is healthy or not can be conveniently judged according to the reaction result.

All possible combinations of the technical features of the above embodiments may not be described for the sake of brevity, but should be considered as within the scope of the present disclosure as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several implementation modes of the present application, and the description thereof is specific and detailed, but not construed as limiting the scope of the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application.
