Description

Technical Field

[0001] This utility model belongs to the field of pressure sensor technology, specifically relating to a pressure sensor for a hemodialysis device detector. Background Technology

[0002] The hemodialysis device calibrator is a specialized testing device used to calibrate hemodialysis machines in hospitals. It calibrates the flow rate, pressure, conductivity, and temperature of the hemodialysis machine. The calibrator consists of a tablet computer, controller, flow sensor, pressure sensor, conductivity sensor, and connecting cables. Each sensor detects its parameters and transmits the data to the controller via the connecting cables. The controller connects to the tablet computer via a wireless or wired network, allowing for parameter calibration and data management. Traditional pressure sensors have complex structures and lack a fixed mounting structure, requiring external clamps for fixation. This makes installation inconvenient, and the installation and disassembly process is cumbersome, making them difficult to install and fix in small spaces. Utility Model Content
