Blood purification device with anticoagulation effect

Abstract

The invention discloses a blood purification device with an anticoagulation effect, which comprises a main shell, a purification mechanism is fixedly mounted in the main shell, one end of the purification mechanism is communicated with a pipeline temperature controller, and the purification mechanism comprises a blood pump, a vein tube, a semi-permeable membrane filter, an artery tube and an adapter tube. And an output port is fixedly formed in one side of the bottom of the blood pump, and the bottom end of the output port communicates with one end of the vein tube. According to the invention, blood flowing into the arterial duct is purified by the semi-permeable membrane filter, is guided into the venous duct, is subjected to temperature regulation by the pipeline temperature controller, is kept at 35-36 DEG C stably in the venous duct, and flows back to a blood circulation system of a patient, so that the problem that the blood in the venous duct is heated and coagulated by an external high-temperature environment is prevented; and the problem that the body temperature of the patient is reduced and the patient feels uncomfortable due to the fact that the blood in the venous duct is cooled by an external low-temperature environment can be avoided.

Description

technical field [0001] The present invention relates to the technical field of medical appliances, in particular to a blood purification device with anticoagulation effect. Background technique [0002] With the improvement of people's living standards and the increase of health awareness, hemoperfusion has been widely accepted as a disease treatment method. Its range of use is getting wider and wider, and the treatment scope has involved drug poisoning, uremia, kidney disease, immune system disease and other fields. The function of renal function recovery and removal of various cytokines and inflammatory mediators. [0003] In the prior art, such as the "blood purification device" of CN 109789259 B, which includes: an accepting mechanism (6), the accepting mechanism (6) can accept a prescribed amount of dialysis necessary for blood purification treatment The dialysate circulation line (dialysate introduction line (L1) and dialysate discharge line (L2)), which can introduc...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a blood purification device with anticoagulant effect to solve the safety and comfort of the patient during blood purification proposed in the above background technology, which is often affected by the indoor temperature, the patient's own temperature and the blood return temperature. Generally, the temperature of the returning blood will not exceed 37 degrees, because there is a risk of hemolysis if the temperature exceeds 37 degrees, but the temperature is too low will also cause the patient's body temperature to drop and cause discomfort such as chills and cramps. The existing blood purification device maintains the blood in time during purification Temperature, after the blood is exported from the purification device, it will be input into the patient's body through an external catheter, and the temperature of the blood exposed to the external catheter cannot be kept from being affected by the ambient temperature in an overheated / too low environment
