AI Technical Summary

Technical Problem

The water bath lid design of traditional endotracheal intubation testing devices results in a compact operating space, making it difficult to place the device properly and affecting the reliability and accuracy of test data. Furthermore, the lid cannot stably maintain the position of the tubing and airbag during heat conduction simulation tests.

Method used

The design incorporates a guide tube positioning frame and a lifting mechanism. The pot lid is suspended in mid-air by the guide tube positioning frame and kept tilted by a torque component to reduce spatial interference. The test piece is fixed in position by the guide tube positioning clamp to ensure stability.

Benefits of technology

The operation of the pot lid is simplified, providing more operating space, reducing testing errors, ensuring stable positioning of the test piece in hot water, and improving the accuracy and reliability of the test.

Abstract

The utility model discloses a tracheal cannula comprehensive performance testing arrangement, including test organism, the inside embedded fixed water bath kettle body of test organism, the top of water bath kettle body is provided with the pot cover, and the inside of water bath kettle body is provided with the support mechanism, and the support mechanism includes fixed bolster and catheter positioning frame, and the one end of fixed bolster upper surface is rotatably connected in catheter positioning frame, and the one side surface of catheter positioning frame is arranged and fixed with catheter positioning clamp, and the below of pot cover is provided with elevating system, and elevating system includes elevating slide sleeve, and the inside sliding connection of elevating slide sleeve has elevating slide bar, the utility model discloses the design of catheter positioning frame support pot cover makes pot cover not to need to take down completely to realize the state of suspension of " to use " through the standing of catheter positioning frame. This design completely solved the problem that traditional separation type pot cover is difficult to place properly because of the compactness of test organism mesa space, and the operation process of pot cover taking is simplified.
