[0033] Example:

[0034] Please see Figure 1-6 This embodiment provides a swab sampler, including a sampler body 1 and a sampler sleeve 2 that matches the sampler body 1. The sampler body 1 and the sampler sleeve 2 are detachably connected.

[0035] The sampler body 1 includes a liquid storage chamber 101, a first connecting structure, a break member 104, a second connecting structure, a swab body 107, and a sampling body 108. The liquid storage chamber 101 is connected to the first connecting structure. The liquid storage chamber 101 contains a test reagent 1011 and a break member 104. The upper end of the second connecting structure is connected to the break member 104, and the lower end is connected to the swab body 107. The sampling body 108 is sleeved on the lower end of the swab body 107, and the first connecting structure is sleeved on the outside of the second connecting structure.

[0036] Both the second connecting structure and the swab body 107 are hollow inside and have a through structure. When the connection between the broken piece 104 and the second connecting structure is broken by external force, the test reagent 1011 flows sequentially through the inside of the second connecting structure and the inside of the swab body 107 to the sampling body 108.

[0037] In an optional embodiment, the liquid storage chamber 101 and the first connecting structure can be integrally formed or fixedly connected; the broken piece 104 and the second connecting structure can be integrally formed or fixedly connected.

[0038] In one specific embodiment, the liquid storage chamber 101 is made of a soft material, such as PVC (polyvinyl chloride), PE (polyethylene), PP (polypropylene), TPE (thermoplastic elastomer), etc.; the test reagent 1011 pre-filled inside the liquid storage chamber 101 is a liquid reagent that meets the test requirements.

[0039] The first connection structure includes a first connector 102 and a second connector 103, and the liquid storage chamber 101 is connected to the second connector 103 through the first connector 102;

[0040] The second connection structure includes a third connector 105 and a fourth connector 106, and the broken piece 104 is connected to the fourth connector 106 through the third connector 105;

[0041] The first connector 102 is matched with the third connector 105, and the second connector 103 is matched with the fourth connector 106;

[0042] The first connector 102 is connected to the third connector 105 via a seal 1051.

[0043] In an optional embodiment, the first connector 102 is a diameter gradient structure with an upper diameter smaller than the lower diameter, and the third connector 105 is a structure with equal upper and lower diameters or a diameter gradient structure with an upper diameter smaller than the lower diameter.

[0044] The second connector 103 has a diameter gradient structure with the upper diameter being smaller than the lower diameter, and the fourth connector 106 has a structure with the upper and lower diameters being equal or a diameter gradient structure with the upper diameter being smaller than the lower diameter.

[0045] The upper end of the sampler sleeve 2 is located between the second connector 103 and the fourth connector 106. The diameter of the sampler sleeve 2 is smaller than the upper end diameter of the second connector 103 and larger than the upper end diameter of the fourth connector 106.

[0046] When the fourth connector 106 has a structure with equal diameters at the top and bottom, the upper end of the sampler sleeve 2 is connected to the fourth connector 106 via a movable connection or a threaded connection to achieve a detachable connection between the sampler body 1 and the sampler sleeve 2; when the fourth connector 106 has a diameter gradient structure with the upper diameter smaller than the lower diameter, the upper end of the sampler sleeve 2 is connected to the fourth connector 106 via a movable connection to achieve a detachable connection between the sampler body 1 and the sampler sleeve 2.

[0047] In an optional embodiment, the fourth connector 106 has an inverted U-shaped structure, and the upper end of the swab body 107 is connected to the top of the inner wall of the fourth connector 106.

[0051] In a preferred embodiment, since the sampling body 108 is usually made of medical absorbent cotton, which has a high density, in order to avoid the test reagent 1011 from being obstructed due to the internal pressure of the cavity, at least one vent hole 1071 is provided at the lower part of the swab body 107, and the vent hole 1071 is located at the upper end of the sampling body 108; optionally, the number of vent holes 1071 can be one, two, three or other.

[0052] In this embodiment, medical personnel first remove the sampler sleeve 2 from the sampler body 1, and use the sampling body 108 to collect biological samples. After sampling, the sampler sleeve 2 is reattached to the sampler body 1. Then, external force is used to break the connection between the broken piece 104 and the third connecting piece 105, allowing the detection reagent 1011 in the reservoir 101 to flow sequentially through the broken piece, through the interior of the third connecting piece 105, the interior of the fourth connecting piece 106, and the interior of the swab body 107, to the sampling body 108, completing the detection. This embodiment integrates the sampling swab and the detection reagent into the same sampler, allowing for immediate detection after sampling. It eliminates the need to consider sample storage conditions or perform transfer operations, resulting in a simple structure, easy operation, and high accuracy of the detection results. It avoids inaccurate results caused by sample storage or transfer issues.
