Doru Dumitru PALADE PhD student: eng. Bogdan Marius CIUREA Abstract This PhD thesis deals, with the theoretical and experimental, testing of lung ventilators. In this thesis, after analyzing pneumatic diagrams from multiple devices, it’s been developed a general pneumatic block diagram of the ventilator, valid for any manufacturing company or medical area it serves. Each unit is presented with its functional role and constructive representative variants. Current test methods are shown focusing on what needs to be improved. Is conceived and developed a unitary testing system that can test lung ventilators in terms of ventilation parameters, patient blocks, nebulizer, and for anesthesia also the anesthetic vaporizer. The unitary testing system consists of testing system for ventilation parameters and testing system of the patient blocks. In the execution of the system were designed and built electronic control module, a sensor for determining flow direction of the gas, and systems for sensor and valves calibration. In developing the system, which is based on a data acquisition and control system, it was aimed to eliminate human error in the testing process, verify the ventilators function with the patient connected to a artificial breathing machine, automatic generation of system test report, determining all ventilation parameters. For the system command it’s been developed a program in LabView environment. With the unitary testing system experimental determinations were performed on multiple devices, both functional and defect, in order to follow the system reaction in multiple situations. After analyzing the experimental results it is observed that the testing system is functional and provides solutions for testing equipment used for long periods. Utilization of this equipment increases productivity and significantly decrease the amount of equipment required to be transferred to the testing site.
