Background
The measuring method of the intra-abdominal pressure comprises a direct pressure measurement method and an indirect pressure measurement method, and the measurement of the intravesical pressure is currently recognized as a 'gold standard' for indirectly measuring the intra-abdominal pressure and is also currently the most common method in clinic. The method has the characteristics of no wound, simplicity, convenience, feasibility, good correlation and the like.
The general measurement mode is as follows: the patient lies down, the operation is carried out under aseptic condition, a Foley catheter is inserted into the urinary bladder through the urethra, a three-way joint is connected between the catheter and a drainage bag, the urinary bladder is emptied, then 20-100 ml of sterile isotonic saline is injected into the urinary bladder through the three-way joint, and a measuring pipe is connected to the three-way joint for measurement. Such as the one described above in both the 2012205614947 patent and the 2018201162651 patent.
