Description
Technical Field
The invention relates to the field of medicine, in particular to a wireless urine volume monitoring device.
Background
In operating rooms and wards, the urine volume information of the catheterized patient needs to be counted, manual measurement is generally carried out, the medical workload is increased, and real-time monitoring cannot be carried out. Particularly, in the operation process, frequent statistics of urine volume is required to judge the fluid inlet and outlet volume and kidney function and guide transfusion or blood transfusion treatment. However, multiple sterile sheets cover the patient and cover a larger space in the lower part of the operating table, with the surgeon located around the patient; when the urine volume is counted, medical staff often need to avoid the standing area of an operating doctor, squat down the body, properly raise a sterile sheet and read, so that the operation is inconvenient, and the sterile area is possibly polluted. Currently, there are automatic measurement schemes for urine and body fluids, but there are few clinical applications.
The more schemes adopted at present include: weighing method and flow method. The weighing method is to use a weight or pressure sensor to realize an automatic measurement function, use a contact type hydrometer or a photoelectric probe externally clamped on a catheter to measure the urine specific gravity, and obtain the urine volume through weight and specific gravity conversion. The flow method is based on infrared photoelectric sensing technology, measures dynamic liquid drops and calculates the urine volume in an accumulated way. The measurement results are generally presented by adopting a matched display screen, and the signal transmission adopts a wired or wireless mode. Drawbacks of the weighing method: (1) no matter the hook or the tray is adopted, the urine tube is connected with the human body and the urine bag, and the process of urine flowing into the urine bag from the human body is dynamic, so that the weighing accuracy can be influenced. (2) Contact specific gravity causes the risk of cross-infection due to contact with urine. (3) The photoelectric probe externally clamped on the catheter measures the instantaneous specific gravity through the catheter, not the total specific gravity of the discharged urine, but the total specific gravity is needed for calculating the urine volume. (4) Some weighing schemes do not measure urine specific gravity, directly use the density of water to calculate volume, and have large errors especially for surgical, critical and renal dysfunction patients. 2 disadvantages of the flow method: (1) the human urine flows out irregularly and quantitatively, the conditions of no flow and quick outflow exist, the liquid drop size is not fixed, even the liquid drops flow down in a bundle, and the measurement error is large. (2) Although some schemes improve the structure of the droplet forming place, limiting the inner diameter of the urinary catheter and the flow rate of urine at the place, and keeping the droplet size constant and flowing down intermittently as much as possible; however, this increases the risk of obstruction of the urinary tract due to the presence of constituents and crystalline deposits in the urine. Common disadvantages: (1) the operating room environment is suitable for centralizing the urine volume monitoring module in the existing monitor and accessing the anesthesia automatic recording system, no extra monitoring equipment and workload are added, the doctor is facilitated to concentrate on the existing monitor, and the medical quality and efficiency are improved. (2) The ICU and ward environment are suitable for centralized management of urine volume monitors dispersed to a hospital bed, and are generally realized in a workstation mode, so that the improvement of the medical work efficiency and the reduction of the work load of medical staff are facilitated. The existing scheme generally adopts independent monitoring and display units, and cannot meet the two requirements. Therefore, a wireless urine volume monitoring device with excellent performance is a problem to be solved.
