Description

A new type of speed-regulating anti-reflux blood-letting bag

Technical field:

The utility model relates to the technical field of medical supplies, in particular to a novel speed-regulating anti-reflux blood-letting bag.

Background technique:

Hemochromatosis (HC), also known as hereditary hemochromatosis (HHC, HH), is a common chronic iron overload disease and is an autosomal recessive disease; due to inappropriate increase in intestinal iron absorption, resulting in excessive iron Stored in parenchymal cells such as liver, heart and pancreas, leading to degeneration of tissues and organs and diffuse fibrosis, metabolic and functional disorders. If the disease is treated with drugs, the onset is slow and the effect is poor. Venous bloodletting is the main method for the treatment of the disease at present. Through venous bloodletting, the iron load in the body can be quickly reduced, thereby slowing the disease and reducing complications. Generally, bloodletting can be 400~ 500ml, 1 to 2 times a week. In the prior art, venous bloodletting relies on the blood transfusion department to use a special blood donation collection bag to extract venous blood, mainly relying on a vacuum blood bag to extract venous blood, the volume is generally about 350ml, and there is no regulator to control the bloodletting speed, usually It takes 3-5 minutes to fill the blood bag. Too fast bloodletting can sometimes cause adverse reactions to the patient, and even syncope. Patent name: A venous bloodletter (Patent No. ZL 201020177018.6) provides a bloodletter that controls the bloodletting speed by setting an infusion regulator on the infusion vessel. One end of the infusion vessel is inserted into the patient's vein, and the other end is inserted into an empty infusion bottle Bloodletting is performed, but the connection between the blood transfusion tube and the bloodletting bottle is not sealed, nor can it prevent backflow. After bloodletting, blood will overflow and leak due to insufficient capacity, pressure problems or poor sealing, resulting in blood pollution.
