Description

Technical Field

[0001] This utility model belongs to the technical field of urine collection devices, and in particular relates to a 24-hour urine collection detector. Background Technology

[0002] A 24-hour urine sample is an important indicator for clinical diagnosis. Collection requires the patient to collect urine from each of the past 24 hours, thoroughly mix it, and collect approximately 5 ml of urine into a urine test tube. The urine in the test tube is then tested. The general procedure is as follows: The patient prepares a cylindrical container and begins urinating completely into the container at 8:00 AM on the first day, including the first morning urine. Afterward, urine is collected from each urination until 8:00 AM the following morning. The start and end times are recorded to ensure a complete 24-hour urine collection.

[0003] If the patient is not hospitalized, they need to bring their own urine container to the hospital for testing. This is very inconvenient for the patient to carry the urine container. After settling overnight, the doctor or nurse needs to stir the urine before testing. Stirring the urine with the container open not only produces a pungent odor but also easily pollutes the environment and seriously affects the work enthusiasm of medical staff.

[0004] The prior art CN207036507U discloses a multifunctional urine collection and sampling device for 24-hour urine protein testing, including a collection bucket, a fixing cover, a motor, a stirring rod, a sealing cap, a guide nozzle, a discharge tube, a regulating valve, a connecting tube, a first one-way valve, a fixing cylinder, an insertion tube, a second one-way valve, a first spring, a protective sleeve, a piston, a pull rod, and a second spring. This device facilitates the collection and storage of urine excreted by patients. Through its built-in stirring mechanism, it can also uniformly stir the settled urine, effectively avoiding inaccuracies in subsequent test results. Its simple operation greatly improves the convenience for medical personnel.

[0005] The complete 24-hour urine test is complex and time-consuming, which can easily cause anxiety for patients. A crucial step in the 24-hour urine test is proteinuria detection. Proteinuria can indicate various potential health risks and is a broad risk indicator. Proteinuria test strips are a mature testing method that provides rapid results. Therefore, it is necessary to provide a 24-hour urine collection and testing device that can quickly provide preliminary results, reassure patients, or prompt them to undergo initial screening for other diseases without waiting for a complete test report, thus saving them time. Utility Model Content

[0006] The technical problem to be solved by this invention is to provide a 24-hour urine collection detector, which facilitates the collection of 24-hour urine samples and enables rapid detection of urine protein in the collected urine samples.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A 24-hour urine collection detector is provided, including a storage tank. The storage tank has an openable and closable cover on top, an external pipeline interface on the upper surface, and support legs and a flow guide connector at the bottom. A stirring impeller is provided inside the storage tank, with a rotating shaft at its center. One end of the rotating shaft is connected to a motor or a hand crank. The flow guide connector has a flow valve at its upper part and rapid detection interfaces and a liquid outlet interface on its lower sides for communication with a urine test reagent tube, respectively. Silicone caps are provided at the rapid detection interfaces and the liquid outlet interface. A liquid collection needle is provided at the end of the urine test reagent tube facing the rapid detection interface, and a rapid detection area is provided at the end away from the rapid detection interface. The rapid detection area includes a test strip wetting section, a reagent tube sealing cap, and a detection activation cap connected in sequence. A sealing plug is connected to the test strip wetting section inside the test strip through the reagent tube sealing cap. The side wall of the test strip wetting section has a wetting window, and a receiving cavity for accommodating the test strip is provided outside the wetting window. The reagent tube sealing cap has a groove in the middle, and the side wall of the groove has a sealing limiting groove and a detection limiting groove. The shape of the detection activation cap matches the reagent tube sealing cap. The side wall of the detection activation cap has a rib that matches the sealing limiting groove and the detection limiting groove. When in the initial position, the rib is engaged in the sealing limiting groove, and the sealing plug is inserted into the urine test reagent tube to achieve end sealing. When the detection activation cap is pulled outward to engage the rib in the detection limiting groove, the sealing plug is dislodged from the urine test reagent tube, and urine flows into the test strip wetting section and wets the detection area of ​​the test strip through the wetting window.

[0008] Preferably, the outer wall of the reagent tube sealing cap is provided with a safety buckle. When the male buckle of the safety buckle is engaged with the female buckle on the outer wall of the detection start cap, the rib is engaged in the sealing limit groove.

[0009] Preferably, the external pipeline interface is connected to a removable preservative package containing built-in preservative.

[0010] Preferably, the cavity is transparent, allowing the judgment area of ​​the internal test paper to be visible.

[0011] Preferably, the liquid storage tank is provided with a handle on the top.

[0012] Preferably, the liquid storage tank is provided with a handle on its side.

[0013] Preferably, the urine test tube has a urine capacity of 5 ± 0.5 ml.

[0014] Preferably, the capacity of the storage tank is 2750±250ml.

[0015] Preferably, the length of the immersion window is 10±1mm.

[0016] Preferably, the test strip is a urine protein test strip.

[0017] The beneficial effects are as follows: This utility model allows patients to collect 24-hour urine samples at home, has a handle for easy carrying and delivery to the hospital, and has a cover with a built-in stirring impeller, so that medical staff can stir the 24-hour urine in a closed environment, avoiding pollution of the ward environment.

[0018] After the urine sediment is evenly stirred by the impeller, the urine is then poured into a quantitative urine test reagent tube. Once full, pulling the test start cap allows for a quick preliminary test using pre-stored test strips to qualitatively confirm whether the urine contains protein or other potential risks, thus improving urine testing efficiency and ensuring the accuracy of subsequent tests.

[0019] Patients typically have to wait a long time to receive a complete test report when undergoing 24-hour urine testing. This invention combines urine protein test strips with a 24-hour urine collection device to achieve rapid initial testing, providing preliminary results in a short time. This allows patients to understand their condition more quickly, reducing unnecessary anxiety and waiting. Attached Figure Description
