The portable blood-type detection pen is for use in emergency transfusion situations. For example, when an earthquake or some other disaster happens, many people can lose their lives because of the absence of timely transfusions. Medical workers need to know the person’s blood type before being able to provide a transfusion.

Portable blood-type detection pens would allow the rapid determination of blood type and the timely provision of suitable blood, preventing the loss of life from excessive bleeding. Portable Blood Type Analyse Pen has four parts: a disposable needle, a button for the needle spring-back equipment, a display screen for detection results, and suction component.
