Description

Technical Field

[0001] The present application relates to the technical field of sample detection, and in particular to a test card packaging assembly. Background Art

[0002] With the improvement of sample detection technology, a variety of test consumables have been gradually developed. For consumables such as test cards that directly contact samples and are equipped with detection sensors, it is very important to keep the test cards clean and stable before use. Therefore, at present, the test cards are often wrapped with packaging, and then the packaging is heat-sealed to effectively prevent the external environment from polluting the consumables and affecting the detection effect. However, due to the characteristics of the packaging material itself and the heat-sealing technology, new polluting gases are inevitably generated during the heat-sealing process. Some of the polluting gases remain in the sealed packaging, which inevitably pollutes the test card and has an adverse effect on the stability and sensitivity of the sensor. Summary of the invention

[0003] To solve the above problems, the main purpose of this application is to provide a test card packaging assembly that can improve the accuracy of sample testing.

[0004] The present application provides a test card packaging assembly, including a test card, an activated carbon adsorbent, and a heat-sealed packaging bag. The test card includes a sample cavity and an injection channel, wherein a photochemical sensor is provided in the sample cavity, the injection channel connects the sample cavity and the outside, and the sample cavity has a light-transmitting portion so that light can be transmitted through the light-transmitting portion to the sample inside the sample cavity; the heat-sealed packaging piece has a heat-sealed accommodating space, and the test card and the activated carbon adsorbent are accommodated in the accommodating space.

[0005] Since it is currently impossible to effectively treat the polluted gases released by the packaging during the heat sealing process, different from the prior art, the present application adds an activated carbon adsorbent to the packaging component, places the activated carbon adsorbent in the storage space for storing the test card, and utilizes the adsorption effect of activated carbon on the polluted gases to effectively reduce the probability of the test card being contaminated by the gas, protect the sensitivity and stability of the sensor in the test card, and thus improve the accuracy of subsequent sample testing using the test card; at the same time, in addition to adsorbing the gases generated by heat sealing, the activated carbon adsorbent can also serve as a desiccant, and has an adsorption effect on many other gases and dust, further reducing the probability of the test card being contaminated and improving the stability of the test card.

[0017] With the development of sample testing technology, in order to improve the accuracy and comprehensiveness of sample testing, practitioners have gradually developed a variety of testing instruments and test consumables. For test cards, which are in direct contact with samples and have detection sensors, it is very important to keep the test cards clean and stable before use.

[0018] In order to maintain the stability and sensitivity of the sensor in the test card, the test card needs to be in a dry and clean environment. Therefore, at present, the test card is mostly wrapped with packaging, and then the packaging is heat-sealed to form a sealed, relatively dry and clean environment to prevent moisture and dust in the environment from contaminating the test card. Some manufacturers will also add desiccant to the packaging to further reduce the humidity of the sealed environment in the packaging.

[0019] However, due to the characteristics of the packaging material and heat-sealing technology, new pollutant gases are inevitably generated during the heat-sealing process, and some of the newly generated pollutant gases are retained in the sealed packaging. However, the commonly used desiccant ingredients (such as calcium chloride) do not have a strong adsorption capacity for these pollutant gases. Therefore, these pollutant gases will inevitably invade the test card, which may cause the reagents in the test card to deteriorate or have an adverse effect on the stability and sensitivity of the photochemical sensor.

[0020] Based on the problems and inconveniences that occur during the heat sealing process of the current test card packaging, the inventors of the present application have conducted long-term research and experiments. In order to improve or solve the above technical problems, the present application proposes at least the following embodiments.

[0021] Figure 1 Schematic diagram of the structure of an embodiment of the test card packaging assembly of the present application. Figure 1 The present application provides a test card 1 packaging assembly, including a test card 1, an activated carbon adsorbent 2 and a heat-sealed packaging component 3. The test card 1 includes a sample cavity 12 and an injection channel 11. A photochemical sensor 14 is provided in the sample cavity 12. The injection channel 11 connects the sample cavity 12 and the outside. The sample cavity 12 has a light-transmitting portion 13, so that light can be transmitted through the light-transmitting portion 13 to the sample inside the sample cavity 12. In the process of using a detection instrument in conjunction with the test card 1 for detection, the sample is input from the outside into the sample cavity 12 through the injection channel 11, and contacts the photochemical sensor 14 in the sample cavity 12. The light is transmitted through the light-transmitting portion 13 to the sample in the sample cavity 12 of the test card 1. At the same time, the sample undergoes a chemical reaction in the sample, so that the photochemical sensor 14 can detect the sample under the action of light, thereby achieving a detection effect on the sample.

[0022] The test card 1 packaging assembly also includes an activated carbon adsorbent 2, which contains activated carbon components. Activated carbon is a specially treated carbon with a well-developed micropore 41 structure eroded on the surface and inside, that is, it is "activated". This allows the activated carbon component to adsorb polluting gases and dust released by heat sealing, and can also be used as a desiccant for absorbing water.

[0023] The heat-sealed package 3 has a heat-sealed accommodating space 31, in which the test card 1 and the activated carbon adsorbent 2 are both accommodated, thereby being isolated from the external environment to protect the stability of the test card 1. In order to achieve the heat-sealing effect, the heat-sealed package 3 is provided with a polymer material at the position where the heat-sealing seal is required. Such polymer materials can form a strong seal with themselves or other materials under heat and pressure conditions. During the heat-sealing process, such polymer materials will be heated to a molten state, thereby bonding with themselves or other materials, and a strong sealing effect can be achieved after the bonding point is cooled.

[0024] Optionally, the polymer material may include polyethylene (PE) type heat-sealable materials, polypropylene (PP) type heat-sealable materials and other heat-sealable materials, wherein other heat-sealable materials may be ionic polymer materials, ethylene-acrylic acid copolymer materials (EAA), ethylene-ethyl acrylate copolymer materials (EEA), ethylene-methacrylic acid copolymer materials (EMAA), etc.

[0025] In the material design of the heat-sealed package 3, since the test card 1 may be stored in a light-proof, UV-proof, collision-proof, anti-static, anti-corrosion and other composite requirements, the material of the heat-sealed package 3 may also be a laminated design, such as an aluminum-plastic bag. Aluminum-plastic bags can include pure aluminum composite bags and aluminum-plated composite bags. Pure aluminum composite bags generally use a laminated structure of polymer materials and aluminum, while aluminum-plated composite bags generally use a laminated structure of aluminum-plated polymer films and polymer materials. It should be noted that in the composite heat-sealed package 3 material, the polymer material needs to be provided on at least one side of the heat-sealed bonding surface.

[0026] Optionally, the material of the heat-sealed package 3 of this embodiment can be a polyethylene terephthalate layer (PET), an aluminum foil layer, a nylon layer (polyamide fiber) and a polyethylene layer, wherein one side of the polyethylene layer is heat-sealed to form an accommodating space 31, and one side of the polyethylene terephthalate layer is in contact with the external environment. The nylon layer can be arranged between the aluminum foil layer and the polyethylene layer, which can improve the strength, thickness and toughness of the heat-sealed package 3.

[0027] However, when polymer materials are heated, they will inevitably release polluting gases, some of which will remain in the accommodating space 31 and be difficult to discharge, and then contact sensitive devices such as the photochemical sensor 14 through the injection channel 11 of the test card 1, affecting the detection performance of the test card 1. Through the method provided in this embodiment, the activated carbon adsorbent 2 can be used to adsorb these polluting gases in the accommodating space 31, thereby minimizing the probability of the polluting gases contacting the test card 1, which is beneficial to protecting the stability and sensitivity of the test card 1; at the same time, the activated carbon also has the ability to absorb water and dust, so that it can form a more comprehensive protection for the test card 1 and reduce the probability of the test card 1 being contaminated and deteriorated.

[0028] See also Figure 1The heat-sealed package 3 may include a bottom plate 32 and a cover plate 33. The first heat-sealed portion 34 and the second heat-sealed portion 35 are respectively provided at the edges of the opposite sides of the bottom plate 32 and the cover plate 33. The first heat-sealed portion 34 and the second heat-sealed portion 35 are connected by heat-sealing and pressing to bond and seal the bottom plate 32 and the cover plate 33, thereby forming an accommodating space 31 between the bottom plate 32 and the cover plate 33. By dividing the heat-sealed package 3 into at least two parts, the process of packaging the test card 1 and the activated carbon adsorbent 2 can be simplified, the requirement for the flexibility of the material of the heat-sealed package 3 is relatively small, and it is more conducive to industrial production.

[0029] Optionally, when the heat-sealed packaging member 3 is made of flexible material, the flat flexible material contacts and covers the test card 1 and the activated carbon adsorbent 2 during the heat-sealing and pressing process, thereby being affected by the overall contour shape of the test card 1 and the activated carbon adsorbent 2, and forming a accommodating space 31 between the bottom plate 32 and the cover plate 33 that is similar to the overall contour shape.

[0030] Optionally, one of the bottom plate 32 and the cover plate 33 is recessed in a direction away from the other to form a groove 36, the first heat-sealing portion 34 and / or the second heat-sealing portion 35 are arranged around the groove 36, the test card 1 and the activated carbon adsorbent 2 are accommodated in the groove 36, and after the first heat-sealing portion 34 and the second heat-sealing portion 35 are heat-sealed and bonded, a receiving space 31 can be formed in the heat-sealed package 3 at a position corresponding to the groove 36. By using the pre-set groove 36 to accommodate the test card 1 and the activated carbon adsorbent 2, the receiving space 31 and the heat-sealing area can be effectively distinguished, thereby reducing the pressure deformation or damage of the test card 1 or the activated carbon adsorbent 2 when the bottom plate 32 and the cover plate 33 are heat-sealed and bonded, and can also effectively avoid the problem of poor sealing caused by the displacement of the test card 1 or the activated carbon adsorbent 2 during the production process. At the same time, the preset groove body 36 can also provide a buffer space for the test card 1 and the activated carbon adsorbent 2 during transportation. When the entire packaging assembly of the test card 1 collides with the external environment, the test card 1 and the activated carbon adsorbent 2 will not be directly affected by the collision under the protection of the groove body 36.

[0031] Alternatively, if Figure 1 As shown, considering the different structures of different types of test cards 1 and activated carbon adsorbents 2, the difficulty of forming the groove body 36 is different, the bottom plate 32 and the cover plate 33 can form the groove body 36 in a direction away from each other, so as to obtain a better sealing effect.

[0032] Optionally, a buffer material may be provided in the groove 36 to achieve a buffering and shock-absorbing effect on the test card 1 and the activated carbon adsorbent 2 accommodated therein, which is beneficial to improving the stability of the test card 1. For example, a layer of flexible foam material is laid on the inner wall of the groove 36, and the test card 1 and the activated carbon adsorbent 2 are wrapped with the flexible foam material for shock absorption. For another example, a resin anti-slip material is provided on the inner wall of the groove 36 to suppress the shaking of the test card 1 and the activated carbon adsorbent 2 in the accommodating space 31.

[0033] Optionally, a side surface of the groove body 36 close to the test card 1 can be at least partially complementary to the outer contour shape of the test card 1 and / or the activated carbon adsorbent 2 to limit the test card 1 and / or the activated carbon adsorbent 2, thereby reducing the shaking of the test card 1 and / or the activated carbon adsorbent 2 in the heat-sealed package 3 and further improving the stability of the test card 1.

[0034] Figure 2 FIG. 1 is a schematic diagram of another embodiment of the test card packaging assembly of the present invention. Figure 2 As shown, the test card 1 packaging assembly provided by the present application may further include an isolating member 4. The isolating member 4 is disposed in the accommodating space 31, and can isolate the accommodating space 31 into a first space 311 and a second space 312, wherein the first space 311 is used to accommodate the activated carbon adsorbent 2, and the second space 312 is used to accommodate the test card 1.

[0035] In order to enable the activated carbon adsorbent 2 contained in the first space 311 to adsorb the polluted gas that escapes into the second space 312 , the isolation member 4 is further provided with micropores 41 that connect the first space 311 and the second space 312 .

[0036] Optionally, the activated carbon adsorbent 2 may include activated carbon particles 21. When the volume or mass is the same, the granular activated carbon adsorbent 2 has a larger surface area than the block activated carbon, which is beneficial to improve the adsorption efficiency. Therefore, the inner diameter of the micropore 41 can be slightly smaller than the radial size of the activated carbon particles 21, so as to ensure the adsorption efficiency while preventing the activated carbon adsorbent 2 from leaking into the second space 312 through the micropore 41 to contaminate the test card 1.

[0037] Optionally, when the first space 311 and the second space 312 are divided by the separator 4, the first space 311 provided with the activated carbon adsorbent 2 can be arranged at a position closer to the first heat sealing part 34 or the second heat sealing part 35, so as to improve the efficiency of adsorbing pollutant gases.

[0038] Optionally, the outer contour shape of the activated carbon adsorbent 2 can be at least one of powder, crushed, columnar, spherical, fibrous, etc. Its specific outer contour shape can be determined according to the remaining space of the accommodating space 31 after accommodating the test card 1 .

[0039] Optionally, the pore size of the activated carbon adsorbent 2 may be at least one of micropores 41 less than 2 nm, mesopores of 2 nm to 50 nm, and macropores of 50 nm to 200 nm. The pore size of the activated carbon adsorbent 2 is the radial size of the loose pore structure inside the activated carbon, and the pore size affects the specific surface area of ​​the activated carbon and the type of molecules that can be adsorbed.

[0040] Therefore, in actual application, three different pore sizes can exist at the same time, and the specific dosage, outer contour shape, pore shape, pore size distribution, surface chemical properties and ash composition of the activated carbon adsorbent 2 need to be selected according to the specific composition of the pollutant gas, so as to achieve a good adsorption effect on the pollutant gas.

[0041] This embodiment provides an activated carbon adsorbent 2, including spherical activated carbon particles 21 with a total mass of 2 grams.

[0042] Figure 3 2 is a schematic diagram of the structure of another embodiment of the test card packaging assembly of the present application. Figure 3 The heat-sealed package 3 provided in the present application may be a packaging bag. The packaging bag has an opening 37, and a first heat-sealing portion 34 and a second heat-sealing portion 35 are provided at the opening 37. The first heat-sealing portion 34 and the second heat-sealing portion 35 are connected by heat-sealing and pressing, so as to form a containing space 31 in the packaging bag. When packaging, the activated carbon adsorbent 2 and the test card 1 can be placed in the packaging bag through the opening 37; when the test card 1 is used, the test card 1 can also be taken out through the opening 37.

[0043] Optionally, the injection channel 11 can be arranged at an end of the test card 1 away from the first heat-sealing portion 34, the second heat-sealing portion 35, and / or the opening 37. Since the injection channel 11 connects the outside world and the sample cavity 12 in the test card 1, substances that affect the stability of the test card 1 are easily exposed to the photochemical sensor 14 through the injection channel 11, and the heat-sealing area will produce polluted gases, and the opening 37 can be connected to the outside world, both of which are sources of adverse effects. Therefore, during the production or packaging process, the injection channel 11 can be arranged in a position away from the source of adverse effects in the accommodating space 31, thereby relatively increasing the distance between the injection channel 11 and the source of adverse effects, reducing the probability and speed of dust, water vapor, polluting gases and other substances entering the injection channel 11, which is conducive to maintaining the stability of the test card 1.

[0044] Furthermore, an activated carbon adsorbent 2 may be disposed between the adverse influence source and the injection channel 11 , thereby slowing down or “blocking” the process of dust, water vapor, pollutant gas and other substances entering the injection channel 11 to a certain extent.

[0045] Optionally, the activated carbon adsorbent 2 is arranged closer to at least one of the first heat sealing portion 34 and the second heat sealing portion 35 relative to the test card 1, so as to adsorb the pollutant gas released by at least one of the first heat sealing portion 34 and the second heat sealing portion 35 during heat sealing, thereby reducing the efficiency of these gases escaping to the vicinity of the test card 1.

[0046] Optionally, the activated carbon adsorbent 2 can be arranged closer to the injection channel 11 relative to the sample chamber 12, so as to adsorb substances such as dust, water vapor, and polluted gases near the injection channel 11, thereby reducing the probability of these substances entering the sample chamber 12 through the injection channel 11.

[0047] Optionally, there may be more than one activated carbon adsorbent 2. Activated carbon adsorbents 2 may be arranged at different positions in the accommodating space 31, so that the performance of the test card 1 can be further maintained by utilizing the cooperation of these activated carbon adsorbents 2.

[0048] The above descriptions are merely embodiments of the present application and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
