AI Technical Summary

Technical Problem

In existing technologies, the gastric tube and probe are designed as a single unit, which means that if the tip of the gastric tube or the probe is damaged, the probe must be pulled out together and the tube re-inserted, causing risks of mucosal damage, nausea, and aspiration to the patient, and the continuity and accuracy of monitoring cannot be guaranteed.

Method used

A multifunctional tubular gastric blood flow monitor was designed, which adopts a detachable connection mechanism, including a connecting sleeve, a fixing sleeve, a limiting structure and an insertion rod. This allows for independent replacement and maintenance of the gastric tube and the connecting tube. When the probe is damaged, only the connecting tube needs to be replaced, avoiding repeated insertion. The length of the gastric tube can be increased by extending the tube and the delivery tube to meet the needs of different patients.

Benefits of technology

This reduces the risk of mucosal damage and infection during gastric tube replacement, ensures the continuity and accuracy of monitoring, lowers equipment usage costs, and improves the convenience of clinical operation and maintenance as well as the stability of blood oxygen monitoring.

Abstract

The present application belongs to the technical field of medical monitoring, and discloses a multifunctional tubular stomach blood flow monitor, which comprises a monitor, a connecting line arranged on one side of the monitor, a receiver arranged at one end of the connecting line and used for receiving signals, a stomach tube arranged on one side of the connecting line, a connecting tube connected with the stomach tube, a probe arranged in the connecting tube, the probe being connected with the monitor through a wire and used for monitoring blood oxygen saturation, and a connecting mechanism arranged on the stomach tube and the connecting tube. The connecting mechanism can replace the stomach tube or the connecting tube. When the stomach tube is replaced, repeated intubation during replacement can be prevented, mucosal injury, nausea, aspiration risk and interruption of monitoring of the patient can be avoided, treatment continuity can be ensured, the connecting tube can be replaced when the probe is damaged, targeted maintenance can be facilitated, the accuracy of monitoring data can be ensured, and the risk of infection can be reduced.
