Time add the size, highly of length adjustment U-tube of tube for transfusion one, two, to adapt to different use environment and patient.Due to
The pressure balance principle of U-tube both sides, after the total saline of transfusion bag or medicinal liquid input, remaining liquid can be at U-shaped
The two ends of pipe form the water column of certain altitude, transfusion device automatic stopping infusion.Be connected with Murphy's burette one end water column of U-tube is high
Spend identical with the level height of scalp acupuncture insertion vein.
This utility model, by leaving some saline or medicinal liquid in U-tube, make use of U-tube two ends liquid pressure balance
Feature, it is achieved automatic stopping infusion after infusion-completed, it is to avoid blood back situation.Its simple in construction, install, easy to use, prevent back
Blood is effective, it is not necessary to urgent call doctor or nurse pull out pin, slow down the operating pressure of doctor, nurse.
This utility model can be additionally used in without drip stand, the occasion of the long tube for transfusion of need, such as after calamity or medium field, patient's walking way
Closing, during use, scalable stays the position of liquid adjusting means and the size of U-tube, increases or reduces the extensile length of tube for transfusion two
Degree, in order to walking, use transfusion device to infuse without the occasion such as drip stand.It addition, this utility model can be additionally used in lucifuge medicinal liquid
Transfusion.
In brief, this utility model provides one and stays liquid transfusion device, it is possible to be automatically stopped defeated after infusion-completed
Liquid, it is to avoid cause the situation of long-time blood back, has simple in construction, installs with easy to use, cheap, low cost, economical
Benefit advantages of higher.
