1. Project Background
At present, the outbreak of new coronary pneumonia is still spreading in many countries. However, medical resources in many countries cannot meet the hospitalization needs of patients, especially in Africa. Fixed-point isolation has become a good way to stop the spread of viruses. We can find that at the epidemic prevention isolation point, both mild and suspected patients wear masks.This is a good way to reduce cross-infection in isolation points. However, we still need to perform physical tests on them. At the isolation point, medical equipment and testing conditions are scarce and crude. Therefore, I designed a mask with a detection function that can be used to monitor the physical condition of patients at isolation points.
2. Project Design
This product consists of three parts: mask, pressure sensor and monitor. The monitor consists of a chip that stores the program and an LED signal light. We embed the pressure sensor on the surface of the mask, and connect the pressure sensor and the monitor in series to form a circuit.
The principle of this product is to use the pressure sensor to feel the difference between the atmospheric pressure and the lung tracheal pressure during breathing, and the monitor calculates the patient's breathing frequency through a set program. When the breathing frequency is within the normal range, the signal light remains green. When the number of breaths per minute reaches more than 20 times, the signal light turns yellow. When the number of breaths per minute reaches more than 25 times, the signal light turns red.
The medical principle behind this product is designed using the most significant and dangerous symptoms of pneumonia patients, that is, by measuring the respiratory rate to determine whether the patient has difficulty in breathing, thereby helping medical staff to maximize the grasp of the patient's condition at the isolation point, and then make reasonable decisions.
3. Project advantages and original intention
The advantage of this project is that in the face of the shortage of medical resources in underdeveloped areas, the patient's condition at the isolation point is grasped as accurately and timely as possible with the least cost, and reasonable decisions are made according to the condition in order to achieve the optimal use of limited medical resources。Dyspnea is the most important and dangerous symptom of pneumonia patients. Breathing frequency as an indicator to measure dyspnea, can more sensitively and accurately grasp the severity of the patient's condition. The cost of monitoring respiratory rate is also far less than the cost of nucleic acid detection and imaging tests. This greatly saves medical resources and indirectly eases the shortage of medical resources in underdeveloped areas. And this product connects the monitoring of respiratory frequency and the use of masks, which avoids the cost of redesigning other testing equipment, and maximizes the value of masks.
My original intention of creating this product was to alleviate the problem of shortage of medical resources in underdeveloped areas. By designing reproducible and lower-cost tools to help disease detection, and then to improve the monitoring of patients' conditions at isolation points, and to adapt medical resources reasonably, Control the spread of the epidemic in underdeveloped areas.
