Biocompatible polycarbonate hemodialysis blood pump

A project jointly developed by Renal Solutions and the material manufacturer Saab Foundation Innovative Plastics has designed a new blood dialysis blood pump, PulsarTM, made of polycarbonate. The choice of biocompatible material Lexan® HPM has the mechanical and physical properties required for blood pumping while also improving blood compatibility. This grade of material can reduce platelets, leukocytes and fibrinogen bundles, and C3a protein activation, thereby reducing blood clotting. Such a blood pump helps to prevent the thrombus formation on the pump and affect the therapeutic effect.

Combined Flow Closed Cooling Tower

Closed Cooling Tower is operated by circulating water or fluid, which is divided into two closed loops.

1. Circulation in the tower: the circulating water or fluid passes through the hot zone environment. After the water temperature rises, it enters the surface cooler in the tower, and the heat is sent to the environment outside the tower through the surface cooler and ventilation fan. The cooled circulating water or fluid is sent to the heat source by the water pump.

2. Circulation outside the tower: the spray water is sent to the spray system by the water tank through the water pipe. After spraying, the spray water first exchanges heat with the filler, so that the spray water can be cooled rapidly. At this time, the water contacts the surface of the surface cooler for heat exchange. Part of the hot steam is discharged through the ventilation fan, and the cooled spray water drops to the water tank for secondary circulation to form an external circulation for cooling.
