Noninvasive bladder pressure measuring device and measuring method thereof

Abstract

The invention relates to a noninvasive bladder pressure measuring device and a measuring method thereof. The measuring method comprises the following steps of: (1) connecting the measuring device, and inserting and fixing a pressure sensor probe into a water injection soft valve of a urethral catheter; (2) correcting the pressure value in a water bag to be 0 as a measurement initial pressure value; (3) acquiring the pressure in the bladder in real time, and calculating and predicting urination time in real time through a prediction model; and (4) outputting the predicted urination time, giving an alarm sound or outputting a pressure curve. The invention provides a bladder pressure monitoring device capable of noninvasively predicting the time of catheterization in real time and judging a urination disorder type, and a measuring method of the bladder pressure monitoring device. The bladder pressure monitoring device comprises a bladder pressure visualization system which continuously displays the bladder pressure and displays a time-pressure value in a curve form; and a built-in regression prediction model is used for calculating relative time when safe pressure is achieved, and a timely early warning is given to guide a patient or a caregiver thereof to open the urinary catheter in time, so that urine backflow is avoided.

Description

technical field [0001] The invention belongs to the field of medical equipment and relates to bladder pressure measurement technology, in particular to a non-invasive bladder pressure measurement device and a measurement method thereof. Background technique [0002] Indwelling urinary catheter is one of the commonly used nursing operations in clinic. About 40% to 50% of hospitalized patients in China had indwelling urinary catheters. It mainly includes two types of patients, one with voiding disorder as the main clinical manifestation (such as spinal cord injury), and the other with voiding disorder as a complication of other diseases (such as stroke) or preoperative routine (such as cesarean section). Among them, more than 90% of urological patients need to indwell the urinary catheter, and the indwelling catheter takes a long time, and even requires a long-term indwelling catheter (long-term indwelling catheter for more than 28 days). Bacteriuria occurs in almost 100% of...

Problems solved by technology

At present, there are two common problems that can be retrieved to monitor and alarm the intravesical pressure: 1. Set a fixed safe volume and safe pressure value: this requires the patient's fluid input (including drinking water and intravenous infusion, etc.) The speed is relatively uniform, and the compliance of the bladder does not change, so that the urine pr
