Disposable test kits for testing diseases or other physical conditions using body fluids such as urine, blood, saliva, sweat, or other body fluids or tissue lysates of human body (e.g., tissue fluids or tissue lysates extracted from the nasal cavity or throat of human body) have been widely used worldwide because of their advantages of simple operation, fast test results, and reliable test results. The application place of the disposable detection kit can be a laboratory operated by professional personnel, and can also be operated by non-professional personnel at home, school, market, road gate, customs and other places. Such a test kit generally comprises a test strip for detection and a plastic case for housing the test strip, wherein the test strip comprises a sample addition pad, a label pad, a detection pad and a water absorption pad (all four pads are made of water-absorbent materials, but the water absorption of the water absorption pad is the strongest) in this order along the longitudinal direction of the test strip. The plastic box comprises a sample adding hole and a detection result observing hole which respectively correspond to the sample adding pad and the detection pad of the test strip.

Detailed Description

The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.

Referring to fig. 1-18, and particularly to fig. 1 and 2, the present invention provides a portable multi-cell gang detection apparatus 100, wherein the portable multi-cell gang detection apparatus 100 includes a bottom card 10 and at least two detection elements 40 (fig. 1 and 2 show ten detection elements 40 arranged side by side) fixed to the bottom card. The base card 10 is preferably a flat (including sheet-like) structure having a thickness that is substantially less than its length and width (e.g., having a thickness that is at least less than or equal to one-tenth of its length and width), but the base card 10 should have a moderate stiffness and toughness such that it is relatively less susceptible to breakage or irreversible deformation (i.e., the base card 10 should not easily break, bend, stretch, curl, etc. under normal use). For this purpose, the thickness of the bottom card 10 is preferably between 0.05 mm and 2.50 mm; more preferably, the thickness of the bottom card 10 is between 0.10 mm and 2.00 mm; more preferably, the thickness of the bottom card 10 is between 0.20 mm and 1.50 mm; more preferably, the thickness of the bottom card 10 is between 0.30 mm and 1.20 mm; more preferably, the thickness of the bottom card 10 is between 0.50 mm and 1.00 mm (the terms "between a value and B value", "between a value and B value" or similar terms refer to "greater than or equal to a value and less than or equal to B value" of the present invention, but the expressions of the applicant do not intend to limit the scope of the present invention disclosed and/or claimed, and the explanation of the expressions should be applied to the "equivalence principle", that is, technical features or technical solutions which are slightly different from the present invention in numerical or structural sense but not substantially different from the present invention, such as technical features or technical solutions which are easily conceived by those skilled in the art according to the disclosure of the present invention and can substantially realize the same or similar functions as the present invention, should also belong to the scope of the present invention. Preferably, the material of the bottom card 10 is selected from PE or PP materials, or the material of the bottom card 10 includes an aluminum foil bag material (including a composite material containing the aluminum foil bag material). The molecular structure, composition, structure and properties of these materials (including composite materials) are well within the skill of the art, and the contribution of the present invention is not to the materials themselves, but to the selection of these suitable materials to make the bottom card 10 of the present invention. The detecting elements 40 comprise an application pad 42, a label pad 44, a detecting pad 46 and a water absorbing pad 48 in sequence along their longitudinal direction, and a plurality of detecting elements 40 are fixed to the upper surface of the base card 10 by an adhesive substance 80 (fig. 15, fig. 16), such as a pressure sensitive adhesive, a double-sided tape, a solid adhesive, etc., and the application pads 42 of these detecting elements are aligned approximately. "detecting element arranges side by side" mean that detecting element roughly arranges neatly in same direction, make whole detecting element's application of sample pad 42 be located same end and roughly align, make whole detecting element's the 48 other ends that are relative with the application of sample pad of pad that absorb water 48 positions.

Referring to fig. 3, the bottom card 10 forms a through hole 12 penetrating through the upper and lower surfaces of the bottom card in the region between the sample adding pads 42 of two adjacent detecting elements 40, the through hole 12 extends to the edge (or referred to as the end) of the bottom card 10 near the sample adding pad 42 of the detecting element, and the through hole 12 completely breaks the bottom card 10 at the edge or the end to form a plurality of branches 16 completely separated from each other by the through hole 12. Therefore, in the embodiment shown in fig. 3, the through holes 12 completely separate the bottom cards 10 from each other in the region between the sample addition pads 42 of two adjacent detecting elements. The technical scheme has the advantages that: when the liquid sample is added to the sample addition member 42, the excess liquid sample is blocked by the hole 12 and does not flow into the sample addition member 42 of one or two detection elements adjacent thereto (i.e., on the left and right sides thereof), thereby avoiding interference with the two detection elements adjacent thereto. Referring to fig. 7-10, the above technical solution has a drawback: the strength of the bottom card 10 at this end is reduced. After the through hole 12 shown in fig. 3 is formed, in a subsequent automated production process (for example, coding the base card, forming the easy-to-tear line 14, etc.), the end of the base card 10 where the through hole 12 is formed is prone to generate deformation which is not easy to recover on a conveying belt, for example, the end is tilted upwards or hangs downwards as shown in fig. 7-10, if the deformation amount is large, the subsequent automated production is affected, even the machine is stopped, not only is the production efficiency greatly reduced, but also the reject ratio of the product is greatly improved. With the solution shown in fig. 4, although the strength of the bottom card 10 at the end of the sample addition member 42 is ensured, when a liquid sample is added to the sample addition member 42, the detection elements 40 at both sides are easily contaminated by the excessive liquid sample, and the detection fails. Therefore, the utility model also provides the technical proposal as shown in figure 5 and figure 6.

Referring to fig. 5, the technical solution is different from the technical solution shown in fig. 3 in that: the adhesive tape 18 is adhered to the upper surface or the lower surface of the tail end of the branch part 16, and the adhesive tape 18 connects (equivalently, binds together) the branch parts 16 of the bottom card 10, so that the strength of the branch parts 16 is greatly improved, the branch parts 16 are not easy to deform irreversibly in the subsequent processing process, and the technical problem existing in the technical scheme shown in fig. 3 and 4 is solved. After the necessary subsequent manufacturing steps have been completed, the tape 18 may either be left on the final product or the tape 18 may be torn off in a suitable step so that the tape 18 does not remain on the final product.

Referring to fig. 6, the technical solution is different from the technical solution shown in fig. 3 in that: the through hole 12 does not extend to the edge or end of the bottom card 10 near the sample addition pad 42 of the detection element, so that the bottom card 10 remains attached at the edge. Fig. 11-14 show the solution shown in fig. 6 in further detail. The technical problem of the technical solutions shown in fig. 3 and 4 is solved well by the technical solution.

In the present invention, the bottom card 10 is connected to the edge near the sample adding pad 42 of the detecting element, which includes the technical solutions shown in fig. 5 and 6.

In one embodiment, the present invention further comprises an aluminum foil pouch (not shown) for sealing the bottom card 10 and at least two detecting elements 40 fixed to the bottom card 10 in a side-by-side arrangement. That is, after a plurality of detecting elements 40 are fixed to the bottom card 10 side by side and the through holes 12 are formed as described above, the detecting elements are put into an aluminum foil bag (or other components such as a desiccant may be put in the bag), and then the aluminum foil bag is sealed by a heat sealing process to form a sealed package.

Referring to fig. 15 to 18, in other embodiments, the present invention further includes a film 60 adhered to the bottom card 10. The film 60 may be adhered to the upper surface of the base card 10 by an adhesive 90 (fig. 15), or the film 60 may be adhered to the upper surface of the base card 10 by a process such as partial heat sealing or ultrasonic welding (fig. 16). The film 60 is a light and moisture barrier film. The film 60 has a thickness smaller than that of the bottom card 10, and the rigidity of the film 10 is less than that of the bottom card 10. The material of the film 60 is selected from PE, PP or PET material, or the material of the film 60 comprises aluminum foil bag material or the material of the film 60 is composite material. The film 60 and the bottom card 10 form a plurality of closed cavities 62 arranged side by side and isolated from each other, and a plurality of detection elements are respectively sealed in the corresponding closed cavities 62 (as shown in fig. 18).

In some embodiments, the through hole 12 extends only through the upper and lower surfaces of the bottom card 10, but not through the film 60, i.e., the through hole 12 is blocked by the film 60. In other embodiments, the through hole 12 extends from the lower surface of the base card 10 to the upper surface of the film 60, i.e., the through hole 12 extends through both the base card 10 and the film 60, and the through hole 12 can be viewed from the side of the film 60.

The film 60 may be completely or partially torn from the base card 10 during testing using the present invention. For example, when the utility model is used for laboratory or professional inspection institution to examine time measuring, professional detection personnel just can once only take off membrane 60 is whole from end card 10, exposes whole detecting element 40, then will wait to detect a plurality of liquid sample according to the order add in proper order to side by side arranged on sample pad 42 respectively, wait for after the time that sets up in advance, for example 5 minutes, read the testing result in proper order to the order of contrast application of sample is with the testing result record down in proper order. Thus, the detection efficiency can be greatly improved. For personal or home testing, it is generally only necessary to perform one test at a time, and for this reason, in some embodiments, the bottom card 10 and the film 60 form an overlapping tear line 14 and a tear line 64 (the tear lines 14, 64 are shown by dashed lines in the drawings of the specification) in the region between two adjacent closed cavities 62. The tear lines 14, 64 are in the form of dashed lines and include spaced apart break portions and connecting portions. In other embodiments, the easy-tear line 14 may be formed only on the bottom card 10 and not on the film 60, if the film 60 can be easily removed completely at one time. The purpose of design easy tear line 14, 64 is for making things convenient for the utility model discloses portable many units allies oneself with row detection device 100 and falls into a plurality of solitary detecting element along tearing line 14, 64 to make things convenient for individual or family's detection to use, even a plurality of detecting element is independent sealed package, after it used one of them or some detecting element, other detecting element's sealed package can not receive the influence completely.

The above description is only a particular embodiment of the present invention and does not limit the scope of the invention as claimed. All the equivalent structures or equivalent flow changes made by using the contents of the specification and the drawings of the present invention, or the direct or indirect application in other related technical fields, should be included in the protection scope of the present invention.
