Description

Detachable venous pot

Technical Field

The utility model relates to the technical field of medical equipment, specifically a can dismantle vein kettle.

Background

Continuous Blood Purification (CBP) technology has been widely used in patients with various acute and chronic renal failure, severe pancreatitis, severe infection, multiple organ failure, etc. While CBP is intended to last for 24 hours of treatment, it is often the case that treatment is forced to be discontinued. The extracorporeal circulation line and filter coagulation are the main reasons for the forced interruption of the treatment, and the incidence rate is as high as 67.6% -74.6%, and the venous pot determines the reasons for easy coagulation due to the special structure. The venous pot is also called a bubble detector and is positioned in the extracorporeal circulation pipeline before blood is returned to the patient, and the built-in filter screen structure of the venous pot ensures that tiny thrombus in extracorporeal circulation is easy to gather at the position, and the blood is easy to stagnate, flow turbulently and form a 'gas-blood' contact surface and the like in the venous pot to promote the occurrence of blood coagulation. Research shows that the incidence rate of venous kettle coagulation is 23%, and venous kettle coagulation often causes unsmooth blood return of patients, further causes whole pipeline coagulation, increases blood loss of patients, causes the patients to be forced to stop treatment, causes unplanned starting, influences the treatment effect of CBP, and increases economic burden and nursing workload of the patients, so that the prevention of CBP extracorporeal circulation venous kettle coagulation is particularly important.

The existing clinical CBP treatment machines have a plurality of brands and models, wherein AQURIUS machines have a certain share in the market, and blood filtering pipelines and accessories thereof have the characteristic of integration, so that after the venous kettle is coagulated blood, the whole blood filtering pipelines and accessories need to be replaced, the medical expense of patients is increased, the replacement time is longer, the effective treatment time of the patients is shortened, the treatment effect is influenced, and serious patients lose whole extracorporeal circulation blood due to untimely replacement of the venous kettle coagulation blood, and the patients are affected to a certain degree after the patients are cured. For this reason, a new technical solution needs to be designed for solution.
