Description

Technical Field

[0001] The present invention relates to a sampling and testing device for collecting specimens. Background Art

[0002] Currently, many rapid screening products for infectious diseases use oral or nasal specimens for screening, but the current specimen collection methods do not provide an accurate and effective way to quantify the specimen content. If quantitative analysis is required, an additional quantitative experiment must be carried out after specimen collection, but such a procedure is cumbersome and likely to reduce the importance of quantitative analysis due to lack of convenience. Moreover, there is a certain proportional relationship between the rapid screening result, the concentration of the analyte in the specimen, and the buffer in the rapid screening reagent. Therefore, inaccurate quantification will inevitably cause errors in the data results.

[0003] Existing rapid screening products include specimen dropping type, crater-shaped extrusion type, one-piece forming type, and instrument extrusion type. However, in the specimen dropping type, the specimen is dropped into the cartridge with a dropper, and due to different squeezing forces of the dropper, quantification is not possible. The crater-shaped extrusion type cannot control the extrusion force and has poor quantification effect. The saliva collection sponge of the one-piece forming type and the detection cartridge are integrally formed and cannot be quantified. In the instrument extrusion type, the collected saliva together with the cartridge is placed into the detection instrument, and then the detection instrument performs extrusion. However, the instrument extrusion type has the disadvantages of high instrument cost, large volume, and not being suitable for carrying around.

[0004] Therefore, it is necessary to provide a novel and progressive sampling and testing device to solve the above problems. Summary of the Invention

Detailed Embodiments

[0025] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0026] The following only uses embodiments to illustrate possible implementation aspects of the present invention, but is not intended to limit the scope of protection of the present invention. The "a" or "at least one" prefixed to the nouns mentioned in the text does not limit the quantity. According to requirements, it can also be "plural" ones. Such changes in quantity are also within the scope of protection to be described first.

[0027] Please refer to Figures 1 to 7 , which shows a first preferred embodiment of the present invention. The sampling and testing device 1 of the present invention includes a container 10, a filtering unit 20, and a sampling and testing unit 30.

[0028] The container 10 is provided with a chamber 11 and respectively provided with an opening 12 and a drain port 13 at opposite ends. The opening 12, the drain port 13 and the chamber 11 communicate with each other. A plurality of protrusions 101 are provided on an inner wall of the container 10, and the plurality of protrusions 101 radially protrude into the chamber 11; the filtering unit 20 is arranged in the container 10 between the chamber 11 and the drain port 13, and the filtering unit 20 is a filter paper; the sampling and testing unit 30 includes a sampling and testing body 31 and a sampling member 32 made of a deformable absorbent material. The sampling member 32 is arranged on the sampling and testing body 31. The sampling member 32 can penetrate into the chamber 11 and be radially squeezed by the plurality of protrusions 101 to collect a specimen. The sampling member 32 is made of materials such as sponge, swab, or other materials that can adsorb liquid. The sampling member 32 can absorb or adhere to a specimen (such as saliva, or other liquid specimens).

[0029] Thereby, the specimen on the sampling member 32 can be squeezed out by the plurality of protrusions 101, and the volume of the sampling member 32 is fixed by squeezing the sampling member 32 by the plurality of protrusions 101, so as to achieve the effects of collecting the specimen and quantifying; in addition, impurities (such as food residues, or other impurities) in the specimen are filtered by the filtering unit 20.

[0030] The drain port 13 allows the specimen to flow out.

[0031] The number of the plurality of protrusions 101 is at least three. The chamber 11 defines a central axis A, and the plurality of protrusions 101 are circumferentially arranged around the central axis A on the inner wall of the container 10; in this embodiment, the number of the plurality of protrusions 101 is at least four; in addition, the plurality of protrusions 101 are circumferentially spaced apart; so as to uniformly squeeze the sampling member 32.

[0032] Each of the protrusions 101 is a radially convex arc-shaped structure; specifically, each of the protrusions 101 is provided with an arc-shaped guiding surface at the top; accordingly, the sampling member 32 can smoothly pass between the plurality of protrusions 101 to be squeezed, and when the sampling member 32 axially moves and rotates relative to the plurality of protrusions 101, it will not be damaged.

[0033] A through hole 102 is formed between the plurality of protrusions 101. The through hole 102 communicates with the drain port 13 and the chamber 11. The through hole 102 allows the sampling member 32 to pass through. An outer diameter dimension D1 of the sampling member 32 is smaller than a diameter dimension D2 of the opening 12 and larger than a minimum aperture dimension D3 of the through hole 102. The sampling member 32 can smoothly pass through the opening 12 and will not be squeezed at the opening 12 until it penetrates into the through hole 102 and is squeezed, so that the specimen flows out from the drain port 13 and splashing of the specimen out of the opening 12 is avoided.

[0034] The container 10 includes a cylinder 14 and a tube 15. The cylinder 14 sleeves the tube 15. The tube 15 is integrally provided with the plurality of protrusions 101. The cylinder 14 and the tube 15 can be combined with each other (such as welding, bonding or fastening joint); which is beneficial to processing and manufacturing.

[0035] The tube 15 presses against the filtering unit 20 (downward), so that the filtering unit 20 can be stably positioned.

[0036] The container 10 includes a bottom wall 18 and a peripheral wall 19. One end of the peripheral wall 19 is circumferentially connected to the bottom wall 18, and the other end axially extends in a direction away from the bottom wall 18. The peripheral wall 19 encloses the chamber 11 and forms the opening 12 at one end. The container 10 defines a first height H1. The first height H1 is the distance between the opening 12 and the bottom wall 18. Each of the protrusions 101 axially extends to define a second height H2. The second height H2 is smaller than the first height H1; the second height H2 is less than 0.6 times the first height H1. Preferably, the container 10 defines a center line extending radially through the center. Each of the protrusions 101 is lower than the center line. Therefore, the sampling unit 30 needs to penetrate into the chamber 11 to a certain depth before being squeezed by the plurality of protrusions 101, which can prevent the specimen from flowing out of the opening 12 and splashing out and adhering to the user's hand after the sampling member 32 is squeezed.

[0037] The sampling unit 30 further includes a seal 40. The seal 40 is provided on the sampling body 31. The seal 40 can seal against the inner wall of the chamber 11 to block the passage of fluid. The seal 40 is an O-ring. Thereby, an airtight effect is achieved inside the chamber 11. When the seal 40 is pushed downward inside the chamber 11, the air inside the chamber 11 can be squeezed to prevent the specimen from flowing backward and adhering to the user's hand.

[0038] The sampling and testing body 31 is respectively provided with a holding part 33 and a connecting part 34 at two opposite ends. A cover part 35 is radially protruded between the holding part 33 and the connecting part 34 on the sampling and testing body 31. The sealing member 40 is arranged on the sampling and testing body 31 and is located below the cover part 35. The cover part 35 covers the opening 12 to achieve multi-layer protection. Through the cover part 35 and the sealing member 40, when the sample 32 is extruded by the plurality of protrusions 101 to discharge the sample, the sample can be blocked by the cover part 35 and will not be ejected from the opening 12. The holding part 33 can be held by hand to facilitate stably inserting the sampling member 32 into the cavity 11 through the opening 12. In addition, the outer diameter dimension of the cover part 35 is less than or equal to the caliber dimension D2 of the opening 12. The cover part 35 passes through the opening 12 into the cavity 11, and the sampling and testing unit 30 can be guided by the cover part 35 to stably axially move in the cavity 11 without easy yaw, so that the volume of the sampling member 32 extruded by the plurality of protrusions 101 is fixed.

[0039] A through hole 17 is radially penetrated through a peripheral wall 19 of the container 10 adjacent to the opening 12. The through hole 17 communicates with the cavity 11. The sealing member 40 axially passes through the through hole 17, so that the sealing member 40 can achieve an airtight effect only when it passes through the through hole 17 to the lower part of the through hole 17 in the cavity 11, enabling the sealing member 40 to be tightly sealed with the container 10 and smoothly pass through the opening 12 into the cavity 11 adjacent to the opening 12.

[0040] The sealing member 40 can be axially abutted against a top end of the tube body 15, such as Figure 7 to limit the distance that the sealing member 40 advances downward in the cavity 11, so that the sealing member 40 can extrude a fixed volume of sample out of the liquid discharge port 13 during the advancing process to achieve the effect of accurate quantification.

[0041] The connecting part 34 is in an I shape. The connecting part 34 includes a first flange 341 and a second flange 342 which are arranged at intervals. The sampling member 32 is arranged between the first flange 341 and the second flange 342, so that the sampling member 32 is limited between the first flange 341 and the second flange 342.

[0042] Please refer to Figures 8 to 9 which shows a second preferred embodiment of the present invention. The plurality of protrusions 101 are integrally deformed and protruded from the outside to the inside of the tube body 15' of the sampling and testing device 1'. A plurality of concave parts 16 are formed on the outside of the tube body 15' corresponding to the plurality of protrusions 101. Thereby, a plurality of spaces are formed between the tube body 15' and the cylindrical body 14 corresponding to the plurality of concave parts 16 to reduce the contact area between the tube body 15' and the cylindrical body 14, which is beneficial to the combination of the tube body 15' and the cylindrical body 14 and has the advantages of material saving and light weight.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
