Design and Robot Autonomous Wearing of Tactile Perception Nose Clip for Human Respiration Rate Detection

In order to autonomously sense the injured person’s physiological indices like respiration rate and thus take immediate robotic triage in complex disaster scenarios, a nose clip system with tactile perception was designed, and its autonomous wearing method with the help of tactile information and visual information was proposed. A test device for autonomous wearing of nose clip detection was set up. The results show that the nose clip system with tactile perception combined with the proposed wearing method can realize the autonomous detection of the nose clip with a success rate of 86.67% in the disaster scenario where visual information is missing. Compared with the traditional vision method of wearing detection, the success rate is relatively increased by 40%.

I. Introduction

Earthquake disasters pose a serious threat to human life and property. As one of the main causes of death, hemorrhagic shock accounts for 30% to 40% of the total deaths in earthquakes [1, 2]. Among them, about 52% of deaths occurred within 12 hours after injury [3], which shows that the treatment of hemorrhagic shock is extremely time-sensitive. Researches have shown that more than 90% of deaths caused by hemorrhagic shock can be avoided by timely and accurate triage of injured persons [4, 5]. Therefore, improving the detection accuracy and detection efficiency for triage at disaster sites is a key issue.
