Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a non-invasive automatic urination recording device for patients with nocturia. Background Technology

[0002] Nocturia refers to the involuntary waking up at night to urinate, excluding the last urination before falling asleep and the first urination after waking up in the morning. The most typical symptom of nocturia is urinating while sleeping at night. Generally, patients are in a deep sleep and are not easily awakened, and often discover the urination after urinating or upon waking up in the morning. In addition to bedwetting, patients may also experience urinary frequency, urgency, difficulty urinating, urinary incontinence, urinary rheology, and may also experience severe mental and psychological symptoms.

[0003] Existing technologies are mostly designed for patients with urinary catheters or for bladder pressure monitoring. There is a lack of non-invasive automatic voiding recorders for patients with nocturia. Most of them rely on manual recording, which often results in omissions or errors due to patient subjectivity and poor clinical compliance. This leads to inaccurate data and unreliable time recording, which can mislead doctors' judgment and affect diagnosis and treatment. Summary of the Invention

[0006] A further feature of this invention is that an annular positioning plate is fixedly provided on the inner wall of the top of the collecting hopper, and a folded edge is provided on the top of the flow guide shroud. The folded edge is engaged with the positioning plate and connected to the positioning plate by fixing screws.

[0007] A further feature of this invention is that the inner wall of the bottom of the collecting hopper is provided with an internal thread, the collecting cylinder is provided with a cylinder opening, and the outer side of the cylinder opening is provided with an external thread, which is threadedly engaged with the internal thread.

[0008] A further feature of this invention is that the outer side of the collecting cylinder is provided with a protrusion, and the surface of the collecting cylinder is provided with a liquid level observation window with scale lines.

[0009] A further feature of this invention is that one end of the handle is fixedly provided with an installation rod, and one end of the installation rod is connected to the side of the collection hopper by a fixing screw.

[0010] A further feature of this invention is that the inside of the handle is divided into three different cavities by a partition, and the control module, power supply and output module are respectively disposed in the three cavities, and the surface of the handle is provided with through holes communicating with the cavities.

[0011] A further feature of this invention is that both ends of the handle are provided with fixing seats, and the fixing seats are connected to the ends of the handle by fixing screws.

[0012] In summary, this utility model has the following beneficial effects: the flow sensor can accurately detect the amount of urine discharged, and the control module records the time and urine volume and stores it to an SD card. The output module generates an hourly urination report, resulting in higher data accuracy. The collection hopper is designed with a shape that is larger at the top and smaller at the bottom, which is beneficial for collecting urine from patients of different genders and is less likely to cause urine spillage. At the same time, the flow guide can ensure that the urine is completely discharged into the inside of the collection hopper.

[0020] Please see Figures 1-5 In this embodiment of the invention, a non-invasive automatic urination recording device for patients with nocturia includes a collection hopper 1. The top of the collection hopper 1 is larger than its bottom to facilitate urine collection and prevent splashing. A flow guide hood 2 is fitted onto the top of the collection hopper 1. The flow guide hood 2 is funnel-shaped and serves to prevent splashing and guide the flow. A drain port 202 is provided in the middle of the flow guide hood 2. A drain pipe 203 is fixed at the bottom of the drain port 202. A flow sensor 204 and a one-way valve 205 are provided on the surface of the drain pipe 203. The flow sensor 204 is used to detect the amount of urine discharged. The flow direction of the one-way valve 205 is from top to bottom to prevent backflow of urine at the bottom and ensure a seal. To prevent urine leakage, a collection cylinder 3 is threaded at the bottom of the collection hopper 1 to collect urine. A handle 4 is located on the outside of the collection hopper 1. The handle 4 is divided into two parts. On the inside of the handle 4, there is a control module 403, a power supply 404, and an output module 405. The control module 403 contains a clock chip and a microprocessor such as STM32, which records the time and urine volume and stores it to an SD card. The output module 405 is a miniature thermal printer or a Bluetooth transmission module, which generates a 24-hour urine report such as 03:15-200mL, 05:30-150mL. According to the report, the daily urine volume, the number of daily urinations, and the volume of a single urination can be accurately understood. The power supply 404 is a rechargeable lithium battery.
