Longers Hemodialysis Pump MTH81-12 makes dialysis safer and more reliable05-06-2020

In medicine, dialysis is a process for removing waste and excess water from the blood and is used primarily as an artificial replacement for lost kidney functions in people with kidney failure. The two main types of dialysis are hemodialysis and peritoneal dialysis; both remove waste and excess water from the blood but in different ways.

Hemodialysis removes waste and water by circulating blood outside the body through an external filter, called a dialyzer, which contains a semi-permeable membrane. Hemodialysis is the most common way to treat kidney failure. 

How does Hemodialysis Work

In hemodialysis, blood is removed from the body and filtered through a filter called a dialyzer, or artificial kidney, and the filtered blood is returned to the body. To perform hemodialysis, there needs to be an access point in the patient’s body to get the blood from the body to the dialyzer and back into the body.

The blood pump is vital to hemodialysis

The dialysis machine has a blood pump that keeps the blood flowing by creating a pumping action on the blood tubes that carry the blood from the body to the dialyzer and back to the body. Since the aseptic treatment and safe operation of the machines are very important, the blood pump, is the key to hemodialysis.

Longer's Hemodialysis Pump MTH81-12 is specially designed for the hemodialysis machine.  Our pump provide features that are important to efficient dialysis including:

1.Longer peristaltic pump chould meet the hygiene requirement to avoid blood and dialysate contamination during transfer.

-When Longer peristaltic pump transferring the blood and dialysate, the blood and dialysate only contact the bore of the tubing. With the disposable tubing, pump will not contaminate the fluid, and the fluid will not contaminate the pump. And the pump does not require disinfection.

2.Safe for the blood cells: minimal hemolysis

-The low shear, gentle pumping action of Longer peristaltic pump ensures the safe for the blood cells.

3.Improve the operational safety of dialysis machine

-Longer hemodialysis pump MTH18-12 has spring loaded rotor. When the blood pressure is too high, the pump will relief the pressure automatically to prevent the high pressure harm to the patients.

-Longer hemodialysis pump MTH18-12 has manually operated lever, helping to load the tubing easily and run the pump head manually. In case of the power outage, the blood could return to the patient by manually operating the pump.

-Longer hemodialysis pump MTH18-12 is installed with sensor to detect the opening or closing state of the pump head cover. When the pump head cover was mistakenly opened, the sensor will provide a signal to stop the pump to protect the safety of operating personnel.

4.With Longer peristaltic pump, the volume, flowrate and flow direction of the blood and dialysate can be controlled automatically and precisely, which will improve the life quality and reduce the inconvenience for the patient during the treatment.

-Longer peristaltic pump has a variety of control model. The pump can be integrated into the dialysis control system through RS485 interface or analog signal interface to achieve automatic intelligent dialysis solution without human intervention.

-Longer peristaltic pump has a wide range of flow rate, which can be controlled through precise speed control. This ensures that the different flow rate of blood and dialysate for different patients could be satisfied easily.

-Flow rate precision of Longer peristaltic pump is <2%.

5.Longer could provide the customized blood pump by OEM design

-Longer engineers and technical specialist will work closely with you to understand your specification to optimize the pump performance and function, and to ensure the pump will perfectly match the industrial design of the dialysis machine.
