Detailed Description
In order to make the objects, technical solutions and advantages of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present application. It will be apparent that the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without the benefit of the present disclosure, are intended to be within the scope of the present application based on the described embodiments. It is to be understood that some of the technical means of the various embodiments described herein may be interchanged or combined without conflict.
In the description of the present application, the terms "first," "second," and the like, if any, are used merely to distinguish between the described objects and do not have any sequential or technical meaning. Thus, an object defining "first," "second," etc. may explicitly or implicitly include one or more such objects. Also, the terms "a" or "an" and the like do not denote a limitation of quantity, but rather denote the presence of at least one, and "a plurality" of "are used to indicate no less than two.
In the description of the present application, if there is an azimuth or positional relationship indicated by terms such as "upper", "lower", "horizontal", etc., based on the azimuth or positional relationship shown in the drawings, this is merely for convenience of clarity and simplicity in describing the present application, rather than to indicate or imply that the elements referred to must have a specific direction, be configured and operated in a specific azimuth, these directional terms are relative concepts for relative description and clarity, and may be changed accordingly in accordance with changes in the azimuth in which the components are placed in the drawings. For example, if the device is turned over in the figures, elements described as "below" other elements would then be oriented "above" the other elements. The specific meaning of the aforementioned terms in the present application can be understood by those skilled in the art according to the specific circumstances.
In the description of the present application, the term "lamination" includes not only the case of lamination in contact with each other but also the case of lamination with another layer interposed therebetween, unless otherwise particularly emphasized.
Fig. 1 to 6 show a specific embodiment of the test strip with moisture-proof packaging of the present application, which comprises a test strip 3 of a prolate shape, the test strip 3 being adapted to receive a fluid-like test substance (e.g. a body fluid of an organism) so as to present a color or pattern representing the result of the test on the test strip 3 based on a biochemical reaction with the test substance.
The test paper further comprises a first dry film layer 1 (one example of a first film layer), a second dry film layer 2 (one example of a second film layer) and a transparent film layer 4 (one example of a third film layer) which are sequentially laminated from top to bottom.
The first dry film layer 1 may be formed of a high molecular material (such as polyethylene PE) blended with a drying agent (such as molecular sieve, calcium chloride), and has a drying and moisture absorbing function, and is capable of absorbing moisture in contact therewith. The lower surface of the first dry film layer 1 has an upwardly concave receiving groove 1A, and the aforesaid test strip 3 is disposed in the receiving groove 1A. The size of the accommodation groove 1A is slightly larger than the test strip 3, whereby, on the one hand, during the production of the test strip, the test strip 3 can be easily installed into the accommodation groove 1A, and, on the other hand, the positional stability of the test strip 3 in the accommodation groove 1A is facilitated to be ensured, and the test strip 3 is prevented from moving inside the accommodation groove 1A.
The transparent film layer 4 (an example of the third film layer) is directly laminated on the lower surface of the first dry film layer 1, and may be formed of a transparent plastic material. And, the transparent film layer 4 covers substantially the entire lower surface of the first dry film layer 1, thereby allowing the test strip 3 to be held in the aforementioned accommodation groove 1A between the transparent film layer 4 and the first dry film layer 1. In addition, the transparent film layer 4 has a through-hole object dropping opening 4A, and the object dropping opening 4A is located at the notch position of the accommodating groove 1A, so that most of the area of the notch of the accommodating groove 1A is covered by the transparent film layer 4, only the object dropping opening 4A with a through hole structure is left for the object to enter, after the second dry film layer 2 is peeled and removed, the user can drop the object to the test strip 3 in the accommodating groove 1A through the object dropping opening 4A, and further, the visual test result can be obtained through the transparent film layer 4.
The second dry film layer 2 may also be formed of a polymer material (such as polyethylene PE) blended with a desiccant (such as molecular sieve, calcium chloride) having a drying and moisture absorbing function capable of absorbing moisture in contact therewith, such as moisture in the air flowing from the accommodating tank 1A to the second dry film layer 2 via the subject drip port 4A. The material of the second dry film layer 2 is generally the same as that of the first dry film layer 1. The second dry film layer 2 is directly and peelably laminated on the lower surface of the transparent film layer 4, and completely seals the test object drop inlet 4A of the transparent film layer 4 from the lower side. Thus, when the second dry film layer 2 is not peeled off from the transparent film layer 4, the test strip 3 is sealed in the accommodation groove 1A by the second dry film layer 2 and the transparent film layer 4 in a double-blocking manner; after the second dry film layer 2 is peeled off from the lower surface of the transparent film layer 4, only the transparent film layer 4 is left to hold the test strip 3 in the accommodation groove 1A in a sealing manner, but at this time, a part of the test strip 3 is exposed through the test-object dripping port 4A, whereby the user can drip the test object onto the test strip 3 in the accommodation groove 1A via the test-object dripping port 4A.
The lamination force of the transparent film layer 4 and the second dry film layer 2 is larger than that of the transparent film layer 4 and the first dry film layer 1. In this way, the transparent film layer 4 can be prevented from being peeled off together with the second dry film layer 2 in the process of peeling off the second dry film layer 2.
Lamination of the first dry film layer 1, the transparent film layer 4 and the second dry film layer 2 may be achieved with an adhesive disposed therebetween. In this case, the transparent film layer 4 has a different lamination force from the first and second dry film layers 1, 2, respectively, can be achieved by: the amounts or/and the compositions of the adhesive between the transparent film layer 4 and the first dry film layer 1 and the adhesive between the transparent film layer 4 and the second dry film layer 2 are set to be different from each other; or/and, the transparent film layer 4 and the first dry film layer 1 are joined using a larger lamination pressure.
In some embodiments, the lamination force of the transparent film layer 4 and the first dry film layer 1 can be increased to such an effect that: the transparent film layer 4 is laminated non-peelably to the first dry film layer 1, which means that if an attempt is made to separate the transparent film layer 4 from the first dry film layer 1 by hand, the structure of the transparent film layer 4 or the first dry film layer 1 may be damaged (e.g., torn).
In addition, the test paper of the present embodiment further includes a first aluminum foil 5 and a second aluminum foil 6 having a moisture blocking function. Wherein the first aluminum foil 5 is directly laminated on the upper surface of the first dry film layer 1, thereby preventing external moisture (e.g., water vapor in ambient air) from contacting the first dry film layer 1, resulting in shortening the hygroscopic life of the first dry film layer 1. The second aluminum foil 6 layer is directly laminated on the lower surface of the second dry film layer 2, whereby external moisture (e.g., water vapor in ambient air) can be prevented from contacting the second dry film layer, resulting in a shortened hygroscopic life of the second dry film layer 2. In this way, the first drying film layer 1 and the second drying film layer 2 basically only dry and absorb moisture to the environment where the test strip 3 is located, namely the accommodating groove 1A, so as to prevent the test strip 3 from being wetted and losing detection performance, and have longer service life.
In order to avoid the first aluminum foil 5 and the second aluminum foil 6 as the moisture barrier layer from being accidentally detached from the test paper, the present embodiment configures the first aluminum foil 5 and the first dry film layer 1 to be non-peelably laminated, and configures the second aluminum foil 6 and the second dry film layer 2 to be non-peelably laminated. Further, such a configuration can also prevent the first aluminum foil 5 or the second aluminum foil 6 from being accidentally peeled off also when the second dry film layer 2 is peeled off from the transparent film layer 4.
As can be seen from the above description, the test paper adopts the simple skin packaging, and uses less packaging material (for example, the hard plastic housing required by the conventional test paper can be omitted) compared with the conventional test paper, so that the amount of medical waste can be reduced, and the medical waste is mostly treated by adopting the incineration method, so that the test paper provided by the embodiment is beneficial to reducing carbon emission to the environment. In addition, the packaging structure of the test paper is simpler, and the product is smaller in size and convenient to use.
In other embodiments, one of the first and second dry film layers 1 and 2 is replaced by a common PE plastic film without a dry and hygroscopic function, so as to save the packaging cost of the test paper. Illustratively, the second dry film layer 2 is replaced by a common PE film layer, and the second aluminum foil 6 is laminated on the lower surface of the PE film layer to prevent moisture in the environment from entering the accommodating groove 1A through the PE film layer and the test object drop inlet 4A, in which case, since the entire groove wall surface of the accommodating groove 1A is directly defined by the first dry film layer 1, the first dry film layer 1 is in sufficient contact with the air in the accommodating groove 1A, thereby having the capability of guaranteeing the dry environment of the test strip 3.
