Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an intelligently managed indwelling urinary catheter system. Background Art

[0002] Indwelling urinary catheter is a common medical operation in clinical practice, which is used to drain urine and solve problems such as urinary difficulty. However, the traditional management method of indwelling urinary catheter has many shortcomings. At present, medical staff usually rely on experience and regular inspections to judge the patient's urinary catheter status, including urine output, the risk of urine retention, etc. This method is not only inefficient, but also prone to misjudgment. According to statistics, about 30% of urinary catheter care is untimely or inaccurate, resulting in complications such as urinary tract infection and urinary catheter obstruction in patients, increasing the patient's pain and treatment costs. In addition, for the monitoring of urine output, most of the existing methods are through simple scale marking or manual recording, and the accuracy of the data is difficult to guarantee. At the same time, due to the lack of real-time data analysis and early warning mechanisms, it is difficult for medical staff to detect abnormal conditions in time. For example, a sudden decrease in urine output may indicate abnormal renal function, and excessive urine output may be related to improper infusion volume.

[0003] For example, a Chinese patent application with publication number CN107970494A discloses a multifunctional urinary catheter system, which includes an indwelling segment, a collection component, a flushing component, a valve component, a control component and a temperature control component. The collection component includes a collection pipe and a urine collection bag that are connected; the flushing component includes a flushing pipe and a flushing bag that are connected; the indwelling segment, the collection pipe and the flushing pipe are connected through a valve component; the control component includes a pressure sensor, a controller and a collection valve, the pressure sensor is used to detect the urine pressure in the indwelling segment, the collection valve is installed on the collection pipe, and the controller controls the opening and closing of the collection valve according to the pressure data detected by the pressure sensor. The temperature control component can accurately obtain the temperature in the bladder and control the temperature control blanket through the temperature control component. The multifunctional urinary catheter system provided by this scheme controls the opening of the collection valve according to the urine pressure, so that the pressure in the bladder can be accurately maintained, which is conducive to the recovery and promotion of bladder function.

[0004] The above patent provides a multifunctional urinary catheter system, which can assist the patient in the rapid recovery of bladder function. However, the existing urinary catheter system cannot record the flow rate and flow velocity of urine, and is not convenient for measuring urine parameters, which is not conducive to medical staff to understand the patient's physical condition in real time.
