A dialysis machine that regulates blood flow

Abstract

The invention relates to a dialysis machine capable of adjusting blood flow, and belongs to the technical field of medical instruments. The blood flow regulating device includes an introduction pipeline, a pumping pipeline, and a temporary blood storage cavity arranged between the introduction pipeline and the pumping pipeline; a flow sensor is arranged on the introduction pipeline, and the pump A blood pump that can be turned on intermittently is arranged on the outlet pipeline. The present invention adds a liquid temporary storage space to perform "slow storage first, then high-speed release", so that the blood flow in the dialysis process can reach a higher level. Under the premise of ensuring that the blood does not coagulate and the safety of the patient, the blood flow rate is slow when the blood flows through the patient, and the relatively rapid "flow rate change" during the dialysis process is achieved, so as to take into account the patient's health and high-quality dialysis effect, and the patient does not need to create an internal fistula. It can also meet the high blood flow required by high-efficiency dialysis, reduce the pain of the patient, and facilitate the life of the patient. At the same time, problems such as blood vessel collapse, hypotension, and congestive heart failure caused by dialysis are effectively avoided.

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.
