Near infrared spectrum continuous rectum tissue oxygen saturation monitor

Abstract

The invention provides a rectum tissue oxygen saturation monitor which comprises an electrode, a balloon and an in-vitro monitoring component, the electrode comprises a near infrared spectrum electrode, the electrode is attached to the inner wall of the balloon, and the near infrared spectrum electrode is connected with the in-vitro monitoring component through a cable. The monitor disclosed by the invention can be used for effectively early warning ischemia and hypoxia phenomena of local tissues and intervening oxygen supply and demand imbalance of the local tissues, so that complications such as endotoxemia related to postoperative intestinal obstruction and intestinal barrier damage caused by ischemia and hypoxia of intestinal tracts in a perioperative period are prevented; and the method has important clinical value for accelerating postoperative intestinal function recovery and rapid ingestion and drinking.

Description

technical field [0001] The invention relates to a medical instrument, in particular to a near-infrared spectrum continuous rectal tissue oxygen saturation monitor. Background technique [0002] Intestinal tissue is prone to microcirculation disturbance and tissue oxygen supply and demand imbalance under perioperative stress, delaying postoperative recovery of intestinal function, and damage to intestinal barrier function due to intestinal ischemia and hypoxia, leading to endotoxin into the blood and Systemic inflammatory response delays postoperative recovery. [0003] Perioperative intestinal tissue microcirculation disturbance and intestinal tissue oxygen supply and demand imbalance are key factors affecting postoperative complications in surgical patients. Moreover, the imbalance of oxygen supply and demand in intestinal tissue is also a key factor affecting the occurrence of anastomotic leakage after gastrointestinal surgery. Therefore, strengthening dynamic real-time ...

AI Technical Summary

Problems solved by technology

Although existing equipment can be used to monitor the diffuse partial pressure of carbon dioxide in the gastric cavity and pHi (acidity in the gastrointestinal mucosa), this equipment is an intermittent and indirect measurement method, which has monitoring delays and is affected by various external factors Defects make it difficult to meet the actual clinical needs

[0004] Therefore, there is still a lack of clinically available continuous, real-time, and effective monitoring equipment and related consumables for perioperative oxygen supply and demand balance in intestinal tissue, which are used to monitor perioperative intestinal stress status, intestinal tissue blood perfusion and oxygen supply and demand balance ;Enhance dynamic real-time monitoring and management to reduce surgical complications and endotoxemia associated with intestinal barrier dysfunction
