1: With three-way method,negative pressure can be used for blood sampling and positive pressure for infusion, The blue line boday with scales on it can show its depth and the transparent line can be used to show the return of blood for doctors' observation. This line has a good biocompatibility which can help the venous path for 12 months.
2. Principle of the three-way method:The end of the line is closed, around the round plug is the valve, If there is no infusion,with some given pressure,the valve will open outwards for infusion. Under the condition of negative pressure,the valve will be sunken and open inwards to draw blood for sampling.
