Dialysis machine with blood flow capable of being adjusted

Abstract

The invention relates to a dialysis machine with a blood flow capable of being adjusted, and belongs to the technical field of medical instruments. A blood flow adjusting device comprises an introduction pipeline, a pump-out pipeline and a temporary blood storage cavity which is formed between the introduction pipeline and the pump-out pipeline; and a flow sensor is arranged on the introduction pipeline, and a blood pump which can be intermittently started is arranged on the pump-out pipeline. According to the dialysis machine with the blood flow capable of being adjusted, a temporary liquid storage space is additionally formed, and first slow storage and then fast release are conducted, so that the blood flow in a dialysis process reaches a high level. In the premise of guaranteeing against clotting of blood and guaranteeing the safety of a patient, flow velocity change that the flow velocity is low when blood flows through a sick body, and is relatively high in the dialysis process is achieved, thus body health of the patient and an excellent dialysis effect are both taken into account, no internal fistulas need to be formed in the patient, a high blood flow needed for efficientdialysis can be met, pain of the patient is eased, and the life of the patient is made to be easy. The problems of blood vessel collapse, hypotension, congestive heart-failures and the like caused bydialysis are effectively solved at the same time.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a blood flow regulating device and a dialysis machine equipped with the device. Background technique [0002] Clinically, hemodialysis refers to the removal of some waste in the blood through a semi-permeable membrane, and the treated blood flows back into the human body. The hemodialysis machine is used for hemodialysis. It is divided into a blood monitoring alarm system and a dialysate supply system. The blood monitoring alarm system includes a blood pump, a heparin pump, an arteriovenous pressure monitoring module, and an air monitoring module. Module, liquid distribution module, degassing module, conductivity monitoring module, ultrafiltration monitoring module and blood leakage monitoring module and other parts. The working principle of the hemodialysis machine is as follows: [0003] Concentrate for dialysis and dialysis water are prepared into qualified dialy...

Problems solved by technology

[0007] However, the ostomy process brings pain to the patient. After the ostomy, the limbs cannot withstand pressure, lift heavy objects, and measure blood pressure, etc., which brings many troubles to the patient's life.

In addition, if the pursuit of good dialysis effect blindly increases the speed of blood outflow from the patient, it is easy to cause hypotension and blood vessel collapse in patients, and it can also lead to increased cardiac output and even congestive heart failure.
