The structure and characteristics of micro small flow pump

2022-07-22

The blood dialyzer is used to replace the human body's kidney function with one kind of separation device. When the human kidney can not be normal elimination of protein metabolites (such as urea, muscle, liver, uric acid), other wastes such as sulfate, phenol, as well as excess ions (Na +, k +, Cl -) and water, to maintain the body balance; In vitro separation with the aid of a hemodialysis machine is required to maintain life.

 

Hemodialysis machine and fluid delivery machinery, fluid measurement, and control part integrated into a whole, known as a hemodialysis system. It integrates precision machinery, electronics, and the chemical industry as a whole, and is a high-tech product.

 

The blood and dialysate delivery system is composed of two pipeline systems and pumps: blood flow and dialysate flow. Therefore, the flow system of hemodialysis is divided into two parts-extracorporeal circulation system of blood and the dialysate system.

 

The pumps that power the delivery of blood and dialysate are the Blood Pump, heparin pump, concentrate pump, negative pressure pump, and proportional pump. The medical industry uses most hemodialysis machines and dialysis pumps.

 

The concentrated solution pump and negative pressure pump are external gear pumps. The pump body size is very small, gear diameter of about 15 mm, and a pump body diameter of about 40 mm. As the pump dialysate is an electrolyte solution, with corrosion, the pump material should be used stainless steel 316L. The gear uses food-grade PEEK material, has corrosion resistance and abrasion resistance, and avoids because abrasion influences fluid transportation.

 

The maximum flow rate of dialysate should not exceed 500ML/min, that is, 30L/h, which requires a stable flow rate. The maximum design flow rate of the gear pump is 1.5 L/min and the maximum pressure is 6 bar.

 

Micro small flow pump


JONSN micro small flow pump is a high-precision metering pump for sensitive applications such as analysis, diagnosis, and medical technology. With our experience, knowledge, and expertise in hemodialysis, diagnostics, cooling, and pure water applications, our team is committed to developing medical device pump solutions for our partners, and bringing hope and opportunity to patients to achieve a better quality of life.

 

Our renal dialysis and cooling pumps use the latest technology and materials to provide quality assurance. The combination of a sealed magnetic drive and FDA-compliant gears ensures the safety and tightness of liquids. Non-pulsatile gear pump technology provides stable and controllable fluid flow to meet the needs of surgery or patient-specific needs. Advanced Design, strict verification process, and advanced manufacturing process ensure high reliability, high efficiency, and low noise, for our partners and customers to provide long life and fault-free guarantee.

 

The disinfectant chemicals used in renal dialysis equipment are powerful and effective, but they are also corrosive. Micro small flow pump is imported from UK and FDA certified. This material can withstand repeated cycles of chemical heat cleaning and provides stable performance.

 

Our micro small flow pump has a variety of control methods, through the RS485 communication control or analog signal control and dialysis machine control system integration, to achieve an automatic, intelligent dialysis treatment program. The whole dialysis process does not require manual intervention.
