Low-cost Simulator for Radial Artery Sample Extraction (1090-003931)
CE Hours: 0.25 Cost: $0.00
Description:
Due to the need for training in arterial blood gas procedures and the high costs of existing simulators, the team of this project decided to carry out a low-cost simulator with the necessary physiological characteristics for acquiring skills in the aforementioned procedures. To make the simulator, its construction was divided by systems that interact with each other to form another system called a gasometry simulator, so, after an analysis, the existence of the following systems was proposed: 1. The first system is the hand and part of the arm, it is important because it must be realistic, it must be translucent enough to allow to see the color change in the lighting, it must be of the real dimensions, and also the other systems will go inside of this, so it will serve as a container, which was made of silicone designed through modeling, which allows the aforementioned characteristics. 2. The next system is energy, because because we will use electronic components which will be powered by 2 rechargeable 18650 batteries. 3. Lighting system, this system will simulate the blood supply, so it will change from white to red, and this depends on whether or not the Allen test is being performed. 4. We have the pulse simulation system, it must be able to accurately simulate how the pulse in the arteries that involves the Allen maneuver feels. In addition to being able to modify the frequency from 60 to 80 pulses per minute. 5. The system that involves the Allen maneuver must be able to capture whether or not there is pressure in the arteries at the same time, then it must vary between three states. The first is no pressed artery, the second is one of the two pressed arteries, the third is the two pressed arteries. 6. Liquid flow system, through which the simulated blood will pass to be extracted by puncture, developed through latex hoses in anatomical position. 7. Control system The last system we think of is the one in charge of controlling the input and output of signals, this being the one who decides how the palm should light up, what the pulse frequency should be, and whether or not the correct state is entering of the pressure in the arteries, this was designed through an Arduino Nano microcontroller, which allows the control of all systems.
