An anti-blocking and anti-caking structure and method for blood transfusion blood vessels

Abstract

The invention relates to the field of medical treatment, in particular to a hematology-department blood-transfusion-tube blocking-free and anti-caking structure and a method. The hematology-department blood-transfusion-tube blocking-free and anti-caking structure comprises an upper connecting tube, a connecting cover is arranged at the lower end of the upper connecting tube, the upper connecting tube is surrounded by the connecting cover, the connecting cover comprises a wide upper end and a narrow lower end and is a gradually-narrowed arc-shaped shell, and a first-stage filtering structure in the middle is connected onto the arc-shaped shell through a side filtering ring and comprises a lower channel opening; a middle filtering net is arranged in the middle of the lower channel opening and faces a first-stage medicine discharging opening in the lower portion of the upper connecting tube, an arc-shaped structure is arranged above the first-stage filtering structure and surrounds the first-stage medicine discharging opening, and an overflowing route changing opening is formed between the first-stage medicine discharging opening and the arc-shaped structure. In the prior art, direct blocking is generated and dredging cannot be conducted, or dredging cannot be conducted after blocking, or impurities enter the human body and cause injuries. According to hematology-department blood-transfusion-tube blocking-free and anti-caking structure and the method, implementation is safer.

Description

technical field [0001] The invention relates to the medical field, in particular to an anti-clogging and anti-caking structure and method for blood transfusion blood vessels. Background technique [0002] The defective of prior art is: [0003] It is easy to cause obstruction when transfusion or fluid delivery; [0004] Drugs cannot be stored for sustained release during infusion; [0005] At present, there is no suitable storage structure that can realize both filtering and storage functions. Contents of the invention [0006] Purpose of the invention: In order to provide a better hematology blood transfusion vessel anti-blocking and anti-caking structure and method, the specific purpose is shown in the multiple substantive technical effects in the specific implementation part. [0007] In order to achieve the above object, the present invention takes the following technical solutions: [0008] Option One: [0009] An anti-clogging and anti-caking structure for hemat...
