Hou Qianheng, let me help you add your creative explanation!
"During the outdoor activity, the student accidentally fell, and started bleeding what to do? Through consulting the information, we can know that platelet bleeding must be controlled before skin surface bleeding can be controlled, so I invented a medical disinfectant cloth to make the blood stop in the injured part as soon as possible, so as to achieve the purpose of hemostasis. Disinfectant cloth is a special material production process, which is a combination of gauze and cotton cloth. It can not only play the role of hemostasis, but also play the role of disinfection. After using the medical disinfectant cloth to stop the inflammation, after starting the healing machine, the healing machine is a solar charged machine that is ready to heal the wound for children at any time."
