Claims (8)

1. Adhering to the impermeable layer on the outer surface of the diaper, Adhesive diagnostic strips.
2. The aforementioned adhesive diagnostic strip is Includes contact film, diagnostic strip, and protective film, The contact film is placed between the impermeable layer of the diaper and the diagnostic strip to provide a passage to the impermeable layer. The diagnostic strip is placed between a contact film and a protective film and is characterized by reacting with urine or blood absorbed by the diaper to perform a urine test or blood test through a color change. The adhesive diagnostic strip according to claim 1, wherein the protective film is for shielding the diagnostic strip from air.
3. The diagnostic strip may include one or more membranes containing one or more reagents. The adhesive diagnostic strip according to claim 2, wherein the diagnostic strip comprises one or more diagnostic sections containing a reagent that can be tested through a selected one of urine, physiological blood, or blood on a single membrane.
4. The aforementioned adhesive diagnostic strip is Includes contact film, diagnostic strip, and protective film, The contact film includes an adhesive portion that is adhered to the impermeable layer of the diaper. The diagnostic strip includes an adhesive portion that is adhered to the protective film, The protective film includes an adhesive portion that adheres to the impermeable layer of the diaper, as described in any one of claims 1 to 3.
5. The aforementioned adhesive diagnostic strip is Includes contact film, diagnostic strip, and protective film, The contact film includes an adhesive portion that adheres to the impermeable layer of the diaper and an extension portion that can overlap in two layers. The diagnostic strip includes an adhesive portion that is adhered to the protective film, The protective film includes an adhesive portion that adheres to the impermeable layer of the diaper, as described in any one of claims 1 to 3.
6. When no tests or blood tests are performed, the adhesive portion of the contact film is adhered to the impermeable layer of the diaper, so the impermeable layer blocks the reaction between the urine or blood in the pulp layer and the diagnostic strip. An adhesive diagnostic strip according to any one of claims 1 to 3, wherein when a urine test or blood test is required, the adhesive portion or extension of the contact film adhered to the impermeable layer of the diaper is peeled off to cause a reaction between the urine or blood in the pulp layer and the diagnostic strip through the passage in the impermeable layer of the diaper.
7. The diaper with an adhesive diagnostic strip according to claim 1, comprising an adhesive diagnostic strip on the impermeable layer that forms the outer surface of the diaper.
8. The aforementioned diaper is, This includes disposable diapers, disposable diaper panties, disposable pads, disposable liners, disposable sanitary products, and disposable hygiene products. A diaper with an adhesive diagnostic strip according to claim 7, including a belt type or a panty type.

Description

This invention relates to an adhesive diagnostic strip that can be attached to the outside of a diaper to obtain health information through urine or blood tests, and to a diaper to which the strip is attached. While changes in modern society have led to longer human lifespans, this has also resulted in an increase in the number of patients suffering from a variety of diseases. On the other hand, disposable diapers or pads are manufactured and used in a wide variety of types and for diverse purposes, either to prevent leakage of urine or menstrual blood during social activities, or for the convenience of patients in hospitals, nursing homes, or other similar facilities (hereinafter referred to as "hospitals, etc."). In particular, in hospitals and other medical settings, diapers are often used to facilitate movement for patients with dementia or mobility issues, or for the convenience of patient management. On the other hand, periodic urine or blood tests may be necessary for the diagnosis or treatment of a patient. In this case, patients who have difficulty moving on their own or who have physical injuries that make movement difficult will wear diapers. However, in the case of dementia patients or patients with limited mobility, it is difficult to collect urine separately for urinalysis. Therefore, urine absorbed into the diaper is collected via syringe for urinalysis, or, in the case of elderly patients with poor vein access, blood absorbed into the diaper or pad may be collected via syringe for partial blood testing. On the other hand, in recent years, with the advancement of biotechnology, a wide variety of urine test strips, reagents, and biosensors have been developed for urine test items, and a wide variety of blood test strips, reagents, and biosensors have also been developed for essential blood test items. However, these simple diagnostic reagents (or diagnostic strips), which rely on color changes due to biochemical reactions, can sometimes lead to inaccurate results over time. Patients with poor mobility find it difficult to go to a separate location to collect a urine sample for a urinalysis. While diapers are worn to prevent leakage, the process of collecting urine from these diapers with a syringe for testing (using urine strips or diagnostic reagents) can be cumbersome and inconvenient. Therefore, technologies have been developed to improve the inconvenience of separately collecting urine or blood by combining or including diagnostic reagents or diagnostic strips in diapers (or pads). However, prior art from the Korean Intellectual Property Office, "Disposable Absorbent Product Indicating the User's Health Status (Patent Document 1)," discloses a disposable absorbent product that includes a health diagnostic device for urine testing within the urine absorbent layer of the product to facilitate urine testing. It also discloses a disposable absorbent product that uses a transparent backing sheet 2 to allow for easy visual detection of reagent changes. However, while Patent Document 1 reduces the inconvenience of separately collecting urine by including the reagent (or diagnostic strip) in the absorbent layer of the diaper so that it reacts with urine, elderly patients such as those with reduced mobility or dementia, unless constantly supervised by a caregiver, have no choice but to check and change the diaper at a set time several hours after urination. In such cases, while the reagent (or diagnostic strip) contained in the absorbent layer reacts with urine and the results of the urine test can be confirmed, the problem arises that inaccurate results can be obtained if the reaction time has elapsed. Furthermore, prior art from the Korean Intellectual Property Office discloses "Diaper with Disease Diagnosis Function (Patent Document 2)," which includes a disease diagnosis means 100 formed inside the absorbent paper 12 of the diaper 10 to facilitate disease diagnosis (see Figure 1). While Patent Document 2 also reduces the inconvenience of separately collecting urine by including a reagent (or diagnostic strip) in the absorbent layer of the diaper to react with urine, due to the characteristics of diapers designed to prevent urine leakage, the reagent (or diagnostic strip) deteriorates if examined several hours after the reaction with urine, leading to the problem of obtaining inaccurate results. Furthermore, as prior art from the Korean Intellectual Property Office, "Smart Urine Test Pad and Urine Test System Using the Same (Patent Document 3)" discloses a urine test pad that can be attached to a diaper when performing a urine test, containing a waterproof paper 20 with an adhesive layer 10, a urine test paper 30, and an antibacterial nonwoven fabric 50 to facilitate urine testing. Patent Document 3 describes a method where the urine test pad containing the urine test paper is attached to the diaper and reacted directly with the urine, eliminating the hassle of collecting urine and preventing de
