Analysis of postoperative rehabilitation function based on rectal pressure signal processing

Aiming at the functional judgment of clinical rectal patients, this article mainly studies the pressure sensing part of the overall postoperative rectal function tester, discusses the characteristics of the rectal pressure signal obtained by the sensor, and uses wavelet transform algorithm to analyze the rectal rehabilitation status of the patient. This article introduces the current basic conditions of patients with rectal dysfunction, and introduces the research significance of this topic from its background and current research status. The structure of the rectal pressure detection device is briefly introduced, with emphasis on analyzing the rectal pressure signal of the patient obtained by the detection device, preprocessing and analyzing it, and obtaining experimental data that can be referred to by clinicians.
