Background

Hemodialysis (HD) is one of the alternative treatments for the kidney of patients with acute and chronic renal failure. The blood in vivo is drained to the outside of the body and then enters the hemodialysis machine, and the hemodialysis machine carries out substance exchange on the principles of dispersion, ultrafiltration, adsorption and convection of the blood, thereby removing metabolic waste in the blood and maintaining the balance of electrolyte and acid-base; at the same time, the excess water in the body is removed, and the whole process of purified blood reinfusion is called hemodialysis.

When hemodialysis is carried out, special anticoagulant medicines are often used in the whole treatment process, blood of a patient needs to be frequently extracted in the dialysis process for detection, and the condition of a blood system of the patient is determined according to the detection result. When dialysis treatment is carried out, the blood pump of the hemodialysis machine is often stopped rotating due to various factors, so that medicine reflux is caused, and blood sampling detection results are influenced. For example, in hemodialysis, it is often necessary to introduce some special drugs into the patient, such as sodium citrate infusion for anticoagulation, to prevent the patient from blood coagulation in extracorporeal circulation. The connector which can prevent blood backflow in the hemodialysis process and is convenient for blood sampling and medication does not exist at present, and the connector needs to puncture a patient for many times during blood sampling, so that great pain is caused; or medical personnel self-make a plurality of three-way pipes and install in the blood transfusion pipe of connecting patient and dialysis machine, trouble just so also easily cause the pollution.
