DETAILED DESCRIPTION OF THE INVENTION

[0023] The present invention is described hereinafter in detail with reference to the attached drawings and specific embodiments.

Embodiment 1

[0024] This embodiment provides a fluid rapid testing device. As illustrated in FIG. 1, the testing device comprises: a box body 11, a box cover 12 cooperating with an opening of the box body 11, and a protection cover 13 hinged to the box cover 12. The box cover is mainly to isolate the interior of the box body 11 from the outside, and the protection cover 13 is to achieve protection and further enhance the isolation, thereby ensuring that a fluid sample is free of contamination and that a testing structure is accurate. As illustrated in FIG. 2, the testing device further comprises: a fluid sampling swab, a fluid collection chamber 15 operable to accommodate the fluid sampling swab 14 and collect a fluid on the fluid sampling swab 14, and a fluid collection tank 16 in communication with a bottom of the fluid collection chamber 15; wherein an installation sheet 4 is arranged on each of two opposing inner walls of the box body 11, a testing strip 2 extending into the fluid collection tank 16 being arranged inside the installation sheet 4. The fluid collection tank 16 is arranged at a bottom of the box body 11. As illustrated in FIG. 4, a cylindrical collection portion is arranged at the bottom of the box body 11, wherein the collection portion has a pore diameter slightly greater than a pore diameter of a lower opening of the fluid collection chamber 15, the collection portion is in communication with the fluid collection tank 16, and an interior of the collection portion forms an arc shape towards a chamber portion of the collection portion, which facilitates downward flowing of the fluid. A fluid to be tested is sampled by using the fluid sampling swab 14, and the sampled fluid is input into the fluid collection chamber 15 and is isolated from the outside and sealed, and meanwhile the fluid enters the fluid collection tank 16 and is in contact with the testing strip 2, thereby completing the test.

[0025] For ease of operations, the fluid collection chamber 15 may be rapidly opened or closed, and the structure of the fluid sampling swab 14 is improved. As illustrated in FIG. 3, the fluid sampling swab 14 comprises: an operation portion 141 arranged outside the fluid collection chamber 15, a connection portion 142 with an installation portion 144 arranged on a tail end thereof, and a transitional neck portion 143 connecting the connection portion 142 to the operation portion 141. A sampling body 3 is fixed on the installation portion 144, wherein the sampling body 3 may be a structure which is capable of absorbing a liquid and extruding the liquid when a force is applied, for example, cotton, sponge or the like. The operation portion 141 has a diameter greater than an inner diameter of the fluid collection chamber 15. The transitional neck portion 143 is adaptively connected to a mouth portion of the fluid collection chamber 15. When the fluid sampling swab 14 is inserted into the fluid collection chamber 15, the fluid sampling swab 14 is directly adapted to the mouth portion of the fluid collection chamber 15 via the transitional neck portion 143. After the fluid sampling swab 14 is inserted into the fluid collection chamber 15, a specific external force is needed to be applied to pull out the fluid sampling swab 14 from the fluid collection chamber 15. In addition to facilitating the operations, the operation portion has a diameter greater than the inner diameter of the fluid collection chamber 15, which further isolates the outside from the interior of the fluid collection chamber 15, and ensures that the fluid is free of contamination. To further ensure the sealing performance, a sealing ring 1441 in close contact with an inner wall of the fluid collection chamber 15 is arranged on an outer ring of the installation portion 144. When the fluid sampling swab 14 is downward extruded, due to presence of a specific amount of air in the fluid collection chamber 15, a greater extrusion force is needed. As a result, the fluid may not be simply extruded to flow into the fluid collection tank 16. In this case, the fluid sampling swab 14 is provided with a gas exhaust passage axially passing through a body of the fluid sampling swab 14, which solves this problem.

Embodiment 2

[0026] This embodiment provides a fluid rapid testing device. The testing device comprises: a box body 11, a box cover 12 cooperating with an opening of the box body 11, and a protection cover 13 hinged to the box cover 12. The box cover 13 is mainly to isolate the interior of the box body 11 from the outside, and the protection cover 13 is to achieve protection and further enhance the isolation, thereby ensuring that a fluid sample is free of contamination and that a testing structure is accurate. The testing device further comprises: a fluid sampling swab, a fluid collection chamber 15 operable to accommodate the fluid sampling swab 14 and collect a fluid on the fluid sampling swab 14, and a fluid collection tank 16 in communication with a bottom of the fluid collection chamber 15; wherein an installation sheet 4 is arranged on each of two opposing inner walls of the box body 11, a testing strip 2 extending into the fluid collection tank 16 being arranged inside the installation sheet 4. The fluid collection tank 16 is arranged on a lateral side of the box body 11. A fluid to be tested is sampled by using the fluid sampling swab 14, and the sampled fluid is input into the fluid collection chamber 15 and is isolated from the outside and sealed, and meanwhile the fluid enters the fluid collection tank 16 and is in contact with the testing strip 2, thereby completing the test.

[0027] For ease of operations, the fluid collection chamber 15 may be rapidly opened or closed, and the structure of the fluid sampling swab 14 is improved. The fluid sampling swab 14 comprises: an operation portion 141 arranged outside the fluid collection chamber 15, a connection portion 142 with an installation portion 144 arranged on a tail end thereof, and a transitional neck portion 143 connecting the connection portion 142 to the operation portion 141. A sampling body 3 is fixed on the installation portion 144, wherein the sampling body 3 may be a structure which is capable of absorbing a liquid and extruding the liquid when a force is applied, for example, cotton, sponge or the like. The operation portion 141 has a diameter greater than an inner diameter of the fluid collection chamber 15. The transitional neck portion 143 is adaptively connected to a mouth portion of the fluid collection chamber 15. The fluid collection chamber 15 and the box cover 12 form an integral structure, and the fluid collection chamber 15 has a chamber mouth 1 to 5 mm higher than an upper surface of the box cover 12, which is preferably 2 mm in this embodiment. When the fluid sampling swab 14 is inserted into the fluid collection chamber 15, the fluid sampling swab 14 is directly adapted to the mouth portion of the fluid collection chamber 15 via the transitional neck portion 143. After the fluid sampling swab 14 is inserted into the fluid collection chamber 15, a specific external force is needed to be applied to pull out the fluid sampling swab 14 from the fluid collection chamber 15. In addition to facilitating the operations, the operation portion has a diameter greater than the inner diameter of the fluid collection chamber 15, which further isolates the outside from the interior of the fluid collection chamber 15, and ensures that the fluid is free of contamination. To further ensure the sealing performance, a sealing ring 1441 in close contact with an inner wall of the fluid collection chamber 15 is arranged on an outer ring of the installation portion 144. When the fluid sampling swab 14 is downward extruded, due to presence of a specific amount of air in the fluid collection chamber 15, a greater extrusion force is needed. As a result, the fluid may not be simply extruded to flow into the fluid collection tank 16. In this case, the connection portion 142 is in a hollow structure, and the fluid sampling swab 14 is provided with a gas exhaust passage axially passing through a body of the fluid sampling swab 14, which solves this problem. The operation portion 141 comprises an outer operation ring, an intermediate post arranged inside the outer operation ring and communicated with both outside and the fluid collection chamber 15, and a reinforcement rib arranged between the intermediate post and an inner wall of the outer operation ring.
