Abstract

The invention discloses a urodynamic monitor correction method and monitoring system. The method comprises the following steps: S01, obtaining urine flow rate index information by using a urine flow rate measurement module, processing abnormal fluctuations by a wavelet transformation algorithm, and performing synchronizing to a main control module; S02, monitoring an electrocardiosignal accordingto an electrocardiosignal detection module by the main control module and obtaining an electrocardiosignal index in a combination with a wavelet function and an R-wave detection algorithm; S03, constructing a nonlinear wavelet threshold model for the urine flow rate index and the electrocardio index information to remove high-frequency noise, and obtaining preprocessed information; and S04, detecting a position of a R wave peak of the preprocessed information by adopting a wavelet modulus maximum value method to obtain effective information in the electrocardiosignal. The urodynamic monitor correction method effectively reduces error rates of misunderstanding and missing detection, improves a monitoring precision of a monitor, performs a quantitative analysis and a correct diagnosis on lower urinary tract disorders of a patient, and is conductive for doctors to make an accurate treatment scheme according to a diagnosis result.

Description

technical field

[0001] The invention relates to the technical field of clinical medicine, in particular to a method for correcting a urodynamic monitor and a monitoring system. Background technique

[0002] As my country's aging population continues to increase, the number of people suffering from lower urinary tract dysfunction will increase accordingly. The demand for high-performance urodynamic analyzers is also gradually increasing. At present, the urodynamic analyzers owned by the urology departments of domestic hospitals mainly rely on foreign imports. Not only are the operation steps difficult to master when using them, but also the maintenance costs of the instruments are relatively high. Consumables such as pressure measuring catheters and connecting catheters are expensive.

[0003] Therefore, it is very meaningful to develop a urodynamic analyzer with high cost performance, complete functions and convenient operation.

[0004] However, although the existing urod...
