A fluid choke device is added in infusion apparatus which is connected with the hospital's Bluetooth call system, part of the choke is floating in liquid, up and down with the flow of liquid. If the dropping bottle is not changed in a timely manner, the choke will block the flow with a small amount of liquid when the liquid is finished, avoid the blood reflux, and the contact of two parts of the fluid choke will send a signal to the hospital call system to remind nurses to change the dropping bottle timely and reduce the burden of care.
