Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of detection equipment, and in particular to a liquid sample collection device. Background Art
[0002] During the health testing process, since many samples cannot be tested directly (such as dandruff, mucus, etc.), the samples must be diluted as needed into testable sample liquids before testing. However, the existing sample liquid collection equipment has a relatively simple structure, so the sample liquid is prone to spillage during the sample liquid acquisition and sample liquid delivery stages. Summary of the invention
[0003] Based on the technical problems existing in the above background technology, the present invention proposes a sample liquid collection device.
[0004] The present invention provides a liquid sample collection device, comprising: a reagent bottle, a plug and a sampling rod, wherein:
[0005] The reagent bottle is filled with reagents, and a sealing film is provided at the mouth of the reagent bottle to seal it;
[0006] The plug is adapted to the mouth of the reagent bottle so that it can be screwed into the mouth of the bottle and form a seal on the mouth of the bottle. The inside of the plug is provided with a dripping pipe running through both ends of the plug. One end of the plug is covered with a cap, and the cap is provided with a puncture needle.
[0007] The sampling rod is located at one end of the plug away from the cap, one end of the sampling rod is connected to the plug, and the other end of the sampling rod is provided with a sampling head.
[0008] Preferably, one end of the cap has a first assembly groove for the plug to be screwed into, and the end of the cap away from the first assembly groove has a second assembly groove for the reagent bottle to be screwed into, and the bottom of the second assembly groove is provided with a conical protrusion away from the first assembly groove to form a puncture needle.
[0009] Preferably, a protrusion is provided at the bottom of the first assembly groove.
[0010] Preferably, one end of the plug away from the cap is provided with a tube body fixedly connected thereto, and one end of the sampling rod away from the sampling head is inserted into the tube body to form a connection with the plug.
[0011] Preferably, the inner wall of the tube body is provided with an axially arranged limiting strip, and the side wall of the sampling rod is provided with an axially arranged limiting groove for the limiting strip to be inserted into.
[0012] Preferably, the sampling head is made of cotton material.
[0013] Preferably, a plurality of circumferentially arranged ridges are provided on the inner wall of the reagent bottle near one end of the bottom.
[0014] In the present invention, the reagent is sealed in the reagent bottle in advance, and the sampling rod is connected to the plug and placed separately from the reagent bottle. When in use, the sample is collected by the collection head on the sampling rod, the sealing film on the reagent bottle is pierced by the puncture needle on the cap, and the plug is screwed into the reagent bottle, so that the sampling rod can be inserted into the reagent bottle, so that the sample contacts the reagent in the reagent bottle to obtain a sample liquid that can be tested; when the sample liquid needs to be obtained, it is only necessary to remove the cap so that the sample liquid can flow out from the dripping pipe, which is convenient and can well control the dripping amount of the sample liquid, and can also avoid the sample liquid from spilling during the acquisition and inspection stages. BRIEF DESCRIPTION OF THE DRAWINGS
[0015] Figure 1 An exploded view of a liquid sample collection device proposed by the present invention;
[0016] Figure 2 This is a schematic diagram of the internal structure of a liquid sample collection device proposed by the present invention. DETAILED DESCRIPTION
[0017] The technical solution of the present invention is described in detail below through specific embodiments.
[0018] like Figure 1-2 As shown, Figure 1 An exploded view of a liquid sample collection device proposed by the present invention; Figure 2 This is a schematic diagram of the internal structure of a liquid sample collection device proposed by the present invention.
[0019] Reference Figure 1-2 The present invention provides a liquid sample collection device, comprising: a reagent bottle 1, a plug 2 and a sampling rod 3, wherein:
[0020] The reagent bottle 1 is filled with reagents, and a sealing film 4 is provided at the mouth of the reagent bottle 1 to seal it. The plug 2 is adapted to the mouth of the reagent bottle 1 so that it can be screwed into the mouth of the bottle and form a seal on the mouth of the bottle. The plug 2 is provided with a dripping pipe 22 running through both ends thereof. A cap 5 is mounted on one end of the plug 2, and a puncture needle 51 is provided on the cap 5. The sampling rod 3 is located at the end of the plug 2 away from the cap 5, and one end of the sampling rod 3 is connected to the plug 2, and the other end thereof is provided with a sampling head 31.
[0021] When in use, use the collection head on the sampling rod 3 to collect the sample, use the puncture needle 51 on the cap 5 to puncture the sealing film 4 on the reagent bottle 1, and screw the plug 2 into the reagent bottle 1 so that the sampling rod 3 can be inserted into the reagent bottle 1, so that the sample contacts the reagent in the reagent bottle 1 to obtain a sample liquid that can be tested; when the sample liquid needs to be obtained, just remove the cap so that the sample liquid can flow out of the drip pipe 22, which is convenient and can well control the dripping amount of the sample liquid.
[0022] As can be seen from the above, the sample liquid collection device proposed by the present invention is easy to use and carry, and can effectively prevent the sample liquid from spilling during the acquisition and inspection stages.
[0023] In addition, in this embodiment, one end of the cap 5 has a first assembly groove for the plug 2 to be screwed in, and the end of the cap 5 away from the first assembly groove has a second assembly groove for the reagent bottle 1 to be screwed in, and the bottom of the second assembly groove is provided with a conical protrusion in a direction away from the first assembly groove to form a puncture needle 51. When the sample is diluted by the reagent, the cap 5 can be removed from the plug 2 and directly installed on the reagent bottle 1 using the second assembly groove on the cap 5.
[0024] In this embodiment, a protrusion 52 is provided at the bottom of the first assembly groove. When the plug 2 is screwed into the first assembly groove, the protrusion 52 extends into the port of the dripping pipe 22 to form a blockage, thereby improving the sealing effect of the dripping pipe 22.
[0025] In this embodiment, the end of the plug 2 away from the cap 5 is provided with a tube body 21 fixedly connected thereto, and the end of the sampling rod 3 away from the sampling head 31 is inserted into the tube body 21 to form a connection with the plug 2. The arrangement of this structure is convenient for replacing the sampling rod 3, and the length of the sampling rod 3 outside the tube body 21 can be adjusted by controlling the insertion depth of the sampling rod 3 in the tube body 21 to meet sampling needs.
[0026] In this embodiment, the inner wall of the tube body 21 is provided with an axially arranged limit bar, and the side wall of the sampling rod 3 is provided with an axially arranged limit groove for the limit bar to be inserted into. The limit bar cooperates with the limit groove to effectively prevent the sampling rod 3 from rotating in the tube body 21.
[0027] In this embodiment, the sampling head 31 is made of cotton material, so that the surface of the sampling head 31 is soft and has good friction, so that the sample can adhere to the sampling head 31 well.
[0028] In this embodiment, the inner wall of the reagent bottle 1 near the bottom end thereof is provided with a plurality of circumferentially arranged ridges 11. When the sampling rod 3 is inserted into the reagent bottle 1, the sampling rod 3 can be rotated to make the sampling head 31 rub against the ridges 11, so that the sample on the sampling head 31 is quickly dissolved in the reagent.
[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
