[0001] The utility model relates to medical equipment technical field especially, relate to a urine volume monitoring device. BACKGROUND

[0002] In clinical work, monitoring the in-out fluid volume is the key means to evaluate the water and electrolyte balance and body fluid state of patients. For patients after shock, large area burn, major operation, and patients with chronic diseases such as heart disease, kidney disease and cirrhosis ascites, the monitoring of in-out fluid volume can help medical staff to discover the body fluid imbalance in time, prevent and treat related complications. The in-out fluid volume includes the intake and the output, wherein the intake refers to all the liquid volume taken into the patient's body, which not only includes the water directly drunk and the water in food, but also includes medical interventions such as intravenous infusion and blood products; and the output includes urine, feces, vomit, gastrointestinal decompression fluid, bleeding volume and drainage volume such as pleural effusion and ascites. These are all the liquid discharged from the patient's body, which is of great significance to the evaluation of the patient's dehydration state, kidney function and treatment effect.

[0003] For urine, medical staff usually use special measuring cups or urine volume meters with scales to accurately measure the urine volume. For feces, due to the variability of its form and water content, medical staff will estimate the liquid volume of feces according to the estimated weight of feces and the standard water content (such as 150ml / 100-300g). For loose stools or watery stools, they can be collected in a basin and then transferred to a measuring cup for measurement.

[0004] However, patients may not be willing or able to defecate on the bedpan due to privacy, comfort or physical ability restrictions. In addition, the use of bedpans by elderly patients may increase the risk of falling. Therefore, it is more appropriate to defecate directly on the toilet. However, if patients directly defecate on the toilet, it is difficult for medical staff to observe and measure. Therefore, it is necessary to design a urine volume counting device suitable for existing toilets, which can accurately collect and measure the liquid volume of urine and feces without affecting the normal use of the toilet by patients.

[0005] CN213217232U proposes an intelligent stool and urine separation filter for hospitalized patients, which comprises a main body, a cover and a backrest. A stool bag is arranged in the main body, and a urine collection bag is connected to the lower end surface of the stool bag. The cover is arranged on the upper end surface of the main body, and a handrail is connected to the upper end surface of the cover. The backrest is arranged on the right side of the cover, and a weighing scale is arranged in the backrest. A passage is arranged on the front end surface of the backrest, and a connecting rod is arranged in the passage. The front end surface of the connecting rod is connected with a hook, and a placing rod is arranged on the outer surface of the hook. The lower end surface of the main body is connected with a connecting table, and the lower end surface of the connecting table is provided with a load-bearing leg.

[0006] The device is designed to replace the traditional toilet, which can effectively separate the patient's stool and urine through the special hollow material collection basket, and facilitate the medical staff to measure the excrement separately. However, this device is mainly suitable for patients who need to monitor the excretion amount, and is not suitable for patients who do not need to monitor the excretion amount and have normal excretion needs, and has certain limitations. In addition, the cost of the device is relatively high, and since it needs to be used repeatedly, the cleaning work of the collection basket after each use is more tedious, which also increases the complexity of operation.

[0007] In addition, on the one hand, there are differences in the understanding of those skilled in the art; on the other hand, a large number of literatures and patents have been studied by the applicant when making the utility model, but due to the limitation of space, all the details and contents are not listed in detail, but this does not mean that the utility model does not have the characteristics of these prior arts, on the contrary, the utility model has all the characteristics of the prior art, and the applicant reserves the right to add related prior art in the background art.

[0008] In view of the shortcomings of the prior art, the urine volume monitoring device is proposed, especially the urine volume monitoring device which can be conveniently installed on the existing toilet, aiming at solving one or more technical problems in the prior art.

[0009] The limitation of the urine volume measurement device in the prior art is that it is not suitable for ordinary patients who do not need to monitor the excretion amount, and the high cost and the complexity of cleaning work limit its wide application. Therefore, the utility model is proposed to solve the above technical problems, which comprises an annular support part laid on the top edge of the toilet seat and fixed by the toilet gasket cover, and a measurement part arranged in the inner ring structure of the support part and detachably connected with the support part. The measurement part is divided into a stool area and a urine area by a partition plate arranged therein. The stool area comprises a storage cavity for carrying stool and a first measurement cavity below the storage cavity. The liquid filtered by the stool in the storage cavity enters the first measurement cavity through a water permeable layer arranged between the storage cavity and the first measurement cavity. The top of the urine area is open and the bottom is closed to form a second measurement cavity for containing urine.

[0010] The urine volume detection device realizes separation monitoring of stool and urine, and improves the accuracy and convenience of clinical monitoring. The fixing mode of the annular support part ensures the adaptability and stability of the device and the closestool, and the detachable connection of the measuring part improves the flexibility, so that whether the measuring part is installed or not can meet the excretion needs of patients with urine volume detection needs and ordinary patients without urine volume detection needs. Further, the measuring part is designed as a disposable product, which can be directly discarded in a designated area after completing urine volume detection, thereby improving the sanitary standard.
