Abstract
Description
Technical Field
[0001] This utility model relates to the field of urine detection technology, specifically a disposable urine detection device. Background Technology
[0002] Urine testing is a common examination that assesses health status by analyzing urine components. It can screen for diseases such as urinary tract infections, diabetes, and kidney disease. Testing methods include rapid test strips and sophisticated laboratory analysis. Single-use urine tests typically use rapid test strips; the color changes produced by the reaction of the test strip with urine components reflect metabolic function, electrolyte balance, and organ status. It can quickly detect indicators such as urine glucose, urine protein, and occult blood, aiding in the diagnosis of diseases like diabetes and urinary tract infections. Therefore, it is frequently used in physical examinations, disease monitoring, and medication guidance, contributing to the management of chronic diseases.
[0003] In hospitals, many types of conditions require urine testing. Patients receiving high-dose cisplatin infusions require extensive hydration, resulting in large amounts of urine. Patients receiving methotrexate infusions need their urine pH measured to ensure the chemotherapy drugs do not cause kidney damage. However, current disposable urine testing methods require separate instruments for pH measurement and urine volume measurement. Traditional measuring cups and test strips are used separately, making the process cumbersome and inconvenient, especially for elderly patients. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides a disposable urine testing device, which solves the problem that existing pH measurement and urine volume measurement require the use of two different instruments.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a disposable urine testing device, comprising a folding paper box, wherein lifting tabs are provided on both sides of the top surface of the unfolded folding paper box, and a waterproof film is provided on the surface of the lifting tabs and the outside of the folding paper box; pH test strips are provided on the bottom surface of the inner wall of the unfolded folding paper box, and a contrast color development strip is provided on one side of the inner wall of the folding paper box.
[0006] Furthermore, a tearable, disposable anti-pollution patch is provided on the top surface of the pull tab outside the waterproof membrane.
[0007] Furthermore, a pH observation strip is provided along one side of the inner wall of the folded paper box, with the top surface of the pH observation strip attached to the top surface of the folded paper box.
[0008] Furthermore, a capacity scale is provided on one side of the inner wall of the folding cardboard box.
[0009] Furthermore, a water volume color indicator patch is attached to the inside of the capacity scale.
[0010] Furthermore, the bottom surface of the pull tab is symmetrically provided with a fixing adhesive, which can be adhered to the toilet seat.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] The foldable cardboard box facilitates convenient storage of the device; the inclusion of pH test strips and a contrast strip inside combines urine volume measurement and pH detection into one function, eliminating the need for separate operation of two instruments and reducing operational difficulty; the pull-out tab allows patients to easily retrieve the foldable cardboard box, preventing urine spillage due to difficulty in handling; the waterproof film prevents the foldable cardboard box from being damaged by urine, extending its storage time; and the tear-off disposable anti-pollution patch can be removed before retrieving the pull-out tab. To prevent contact with urine that may be present on the pull-up strip; by setting an extended upward pH observation strip, the color comparison area is kept away from urine contamination sources, avoiding color distortion caused by urine soaking the test strip; by setting a volume scale, the patient's urine volume can be displayed; by setting a volume color-changing patch, the target urine volume can be intuitively displayed by color gradient, which is more suitable for visually impaired or elderly patients than traditional measuring cup scales; by setting a fixing adhesive, the entire device can be firmly attached to the toilet seat, solving the problem of traditional measuring cups being easy to tip over, causing sample contamination or measurement interruption.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] like Figures 1 to 5 As shown, a disposable urine testing device includes a folding paper box 1. After the folding paper box 1 is unfolded, two lifting tabs 2 are extended from the top surface. A waterproof film 3 is provided on the surface of the lifting tabs 2 and the outside of the folding paper box 1. A pH test strip 4 is provided on the bottom surface of the inner wall of the unfolded folding paper box 1. A contrast color development strip 5 is provided on one side of the inner wall of the folding paper box 1.
[0021] like Figure 1 As shown, the main improvement of this utility model lies in solving the problem that existing pH measurement and urine volume measurement require the use of two different instruments, such as... Figures 1 to 5 As shown, in this utility model, a disposable urine testing device is used by first removing the folded device from the packaging bag, then unfolding the folded cardboard box 1 and the pull tab 2, and peeling off the outer skin of the fixing adhesive 10 so that the bottom surface of the fixing adhesive 10 is adhered to the toilet seat, thus fixing the folded cardboard box 1. Next, the patient urinates into the folded cardboard box 1. After urination, the patient or medical staff can peel off the disposable anti-contamination patch 6 on the upper surface of the pull tab 2 to prevent the patient or medical staff from touching the urine that may be present on the pull tab 2 with their hands. Then, by taking the pull tabs 2 on both sides of the folded cardboard box 1, the entire device is removed from the toilet seat and placed stably on a flat surface. At this point, because the folding cardboard box 1 is made of sodium alginate composite material, it can withstand the weight of urine for a short period of time. Combined with the waterproof film 3 on the outside, it can maintain its shape for a period of time. The volume scale 8 and the color-changing patch 9 visually display the target urine volume through color gradients. Simultaneously, the pH observation strip 7 absorbs urine and changes color. Medical staff can compare the color of the urine with the color of the contrast strip 5 on the inner wall of the folding cardboard box 1 to determine the pH value, thus combining urine volume measurement and pH detection functions. After the test is completed and the data is recorded, medical staff can use the pull tab 2 to pour the urine from the folding cardboard box 1 into the toilet and flush it. The folding cardboard box 1 will then be disposed of in the medical waste bin. This perfectly meets the closed-loop needs of chemotherapy patients: "extensive hydration - frequent urination - immediate testing," avoiding the compliance barriers caused by the repeated rinsing of containers required by traditional methods.
[0022] like Figures 1 to 5 As shown, a tearable disposable anti-pollution patch 6 is provided on the top surface of the lifting piece 2 outside the waterproof film 3.
[0023] Specifically, by setting a tearable disposable anti-contamination patch 6 on the top surface of the pull-up pad 2, it can be torn off before picking up the pull-up pad 2, preventing patients or medical staff from coming into contact with urine that may be present on the pull-up pad 2, effectively reducing the risk of iatrogenic infection.
[0024] like Figure 1 and Figure 5 As shown, pH test strip 4 extends upward along one side of the inner wall of folded paper box 1 and pH observation strip 7 is provided, with the top surface of pH observation strip 7 attached to the top surface of folded paper box 1.
[0025] Specifically, by extending the pH test strip 4 upward along one side of the inner wall of the folded paper box 1 to form a pH observation strip 7, and with the top surface of the pH observation strip 7 attached to the top surface of the folded paper box 1, the color comparison area can be kept away from the source of urine contamination, thus preventing the test strip from being soaked in urine and causing color distortion.
[0026] like Figure 1 and Figure 5 As shown, a capacity scale 8 is provided on one side of the inner wall of the folding cardboard box 1.
[0027] like Figure 1 , Figure 4 and Figure 5 As shown, a water volume color indicator patch 9 is attached to the inside of the capacity scale 8.
[0028] Specifically, by setting a volume scale 8 on one side of the inner wall of the folded cardboard box 1, the amount of urine produced by the patient can be displayed. A color-changing patch 9 is attached to the inside of the volume scale 8, which can intuitively display the target amount of urine by relying on color gradient. This is more suitable for visually impaired or elderly patients than traditional measuring cup scales.
[0029] like Figure 3 As shown, the bottom surface of the pull tab 2 is symmetrically provided with a fixing adhesive 10, which can be adhered to the toilet seat.
[0030] Specifically, by setting symmetrical fixing adhesive stickers 10 on the bottom surface of the lifting plate 2, the folded paper box 1 can be firmly adhered to the toilet seat, solving the problem that traditional measuring cups are easy to tip over, causing sample contamination or measurement interruption. It is especially suitable for patients who may experience dizziness and muscle weakness after chemotherapy.
[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
