Abstract

The invention relates to a mechanical heart-failure dehydration plant which is realized through peripheral veins, and a control apparatus thereof. The mechanical heart-failure dehydration plant comprises a blood filter unit, a safe detection unit, a blood and ultrafiltration driving unit, an ultrafiltrated weighing feedback regulation unit, and a control unit, wherein, a pressure transducer in the safe detection unit comprises an absolute pressure component and at least a pressure transducer protector. After the control apparatus of the mechanical heart-failure dehydration plant starts, a CPU executes the following steps that are the step of controlling the forced pre-rinse and the step of controlling the ultrafiltration. The mechanical heart-failure dehydration plant and the control apparatus thereof have the advantages of relatively low use-cost, safe ultrafiltration process, and simple and convenient operation.

Description

technical field

[0001] The invention relates to a medical device, especially a device for dehydration of mechanical heart failure through peripheral vein to vein extracorporeal circulation and a control device thereof, mainly used for treating sodium and water retention diseases such as congestive heart failure and intractable edema. Background technique

[0002] Patients with heart failure often have excessive fluid load (preload). Therefore, safe and effective correction of sodium and water retention is one of the effective measures for the treatment of heart failure. At present, hemodialysis / filtration equipment for the treatment of renal failure is commonly used clinically in China to achieve dehydration and achieve the purpose of ultrafiltration and dehydration to correct sodium and water retention in the treatment of heart failure. However, this type of equipment is designed for the treatment of renal failure. The main purpose is to The removal of solutes such as metab...
