Overview
The working principle of the extracorporeal circulation blood pump tube performance tester is very ingenious. In terms of mechanical simulation, it utilizes a biomimetic blood pump device, such as a common peristaltic pump head, to periodically compress the pump tube.

Extracorporeal circulation blood pump tube performance tester
The extracorporeal circulation blood pump tube performance tester has comprehensive performance evaluation capabilities, covering multiple key dimensions such as mechanical performance and safety performance. In terms of mechanical performance testing, it can accurately detect the anti extrusion strength of pump tubes. By simulating the squeezing action of a blood pump and applying varying degrees of squeezing force to the pump tube, it can be determined whether the pump tube can withstand repeated squeezing without rupture or deformation in actual use. In terms of elasticity recovery ability testing, the detector observes the ability of the pump tube to recover to its original state after squeezing it, ensuring that the pump tube can maintain good elasticity and stable blood delivery ability during long-term use. Fatigue resistance testing is also not a problem. By subjecting the pump tube to thousands of cycles of compression, simulating its working state during long-term use, it can detect whether the pump tube will experience performance degradation due to fatigue, effectively avoiding sudden damage to the pump tube due to fatigue during actual dialysis, which could endanger the patient's life safety.
In terms of safety performance testing, the tester also performs well. It can rigorously test the biocompatibility of pump tube materials, evaluate whether the pump tube will cause adverse phenomena such as immune reactions and cytotoxicity when in contact with human blood, and ensure the safety of patient blood during extracorporeal circulation. The anti-aging test is also an important part. By simulating different environmental conditions, such as temperature, humidity, light, etc., the aging process of the pump pipe is accelerated, and its performance changes under different aging degrees are detected to ensure that the pump pipe always maintains good performance within the validity period.
