Pre-hospital medical emergency system for the general public
What is it about?
In China, many heart patients die because they miss the critical four-minute rescue window. Urbanization has delayed emergency vehicle response times, making bystanders the most important rescuers. This project helps the public perform first aid for heart patients and tackles challenges in early emergency care.
As the team leader, I handle all design work and manage the project.
Background
First aid has three stages: pre-hospital care, hospital treatment, and intensive care. In China, the first stage is underdeveloped. Each year, about 540,000 people die from sudden cardiac arrests, mostly due to delays in rescue and complications, not the primary disease.
The critical rescue window is 4 minutes, but ambulances often take over 10 minutes to arrive. Unfortunately, bystanders rarely step in to help during emergencies.
Research
Social Perspective:
-
China faces a serious aging population, leading to growing attention to medical care.
-
Demand for first aid has risen, but the pre-hospital system is lagging behind.
-
First aid knowledge is not widely known or practiced in China.
Economic Perspective:
-
The aging population puts significant pressure on the country’s medical economy.
-
Investment in pre-hospital first aid is much lower than in in-hospital care.
SDI first aid kit
A new type of application multifunctional first aid kit used in public places, mainly used to store CPR auxiliary equipment, AED, medicine box three
Kind of first aid products.
When an emergency occurs, the patient or passerby presses the emergency button, the SDI first aid kit will enter an alarm state, the breathing light will flash, and the emergency
The rescue signal was launched to volunteers qualified for first aid within 2 kilometers. At the same time, the emergency center received a distress signal and
The conditions are processed in a hierarchical manner. After the volunteers arrive at the scene, they will use the APP QR code to verify their identity and open the slide-type first aid kit.
Exit the device and give first aid to the patient according to the above voice prompts and APP steps.
SDI CPR (cardiopulmonary resuscitation) auxiliary device
New and simplified CPR aids, including wearable CPR aids and artificial respiration aids, which combine chest compressions
With the two functions of artificial respiration, the rescuer can perform CPR on the patient at the same time with the help of the equipment to perform the human operation on the patient at a fixed scientific frequency.
Work breathing (delivering air to the mouth) to maximize the efficiency of first aid. The device can autonomously monitor the patient's body number through EAV body monitoring technology
According to data and real-time feedback to the device display screen, and the device is wearable, its own weight and thickness are almost the same as clothes, and its flexible DuPont
The fixing method of Lycra fabric and silicone strap enables the device to fit the human body to the greatest extent and meet the needs of patients of different sizes.

SDI AED (cardiac defibrillator)
SDI AED is different from general AED in that this product is small in size, easy to carry and store, and more suitable for pre-hospital first aid. On the premise of retaining the perfect function, the volume becomes smaller, and the unique "North Point" positioning method of the electrode pad and the fixed angle processing method between the electrode pads can make the user more convenient to locate the defibrillation position. In order to achieve the best electric shock effect.
*The national utility model patent has been declared
SDI medicine box
The medical box after reasonable space allocation mainly stores medical supplies that are fixed and hemostatic, such as bandages, triangles, and disinfectant. All supplies are packed in separate boxes.
