Portable power-free automatic infusion set

This is a portable automatic infusion device that can work without power supply and gravity. It is suitable for emergency rescue work in disaster areas. It can automatically operate under the environment of no power supply and no lifting infusion device to input 300ml of liquid medicine for the wounded. The device is composed of a medicine bottle, a piston, a compression spring, a shell, a valve and other core components. Its principle is that the piston is pushed by the compression spring to input the liquid into the wounded body. First aid personnel can accurately control the flow rate of the liquid by rotating the valve to adapt to different wounded (accurate to drops/minute).
