Valve in the tube / Valve in the tube

Valve in the tube
Valve in the tube

It is very terrible to fall asleep when being infused alone. When liquid inside the infusion bottle is completely injected, the patient won’t feel it. At this moment, the blood will flow back to the infusion tube. When the patient wakes up and sees the blood in the infusion tube, he may feel a certain degree of panic.
The valve is a membrane structure that can be opened and closed in a person or animal’s organs and acts as a one-way valve, to make blood flow from one direction to another, without backflow. The transplant of this kind of structure into the infusion tube can prevent excessive blood return.
