The Design Of Remote Control Of Special Ventilator In COPD

Chronic obstructive pulmonary disease is called COPD.lt is a devastating disease of the lungs.A not completely reversible disease characterized by airflow limitation,he airflow limitation was usually progressive development and related to abnormal inflammatory response of the lungs of harmful particles or gases.Clinical manifested as recurrent cough, sputum, shortness of breath and gradually worsening difficult or labored breathing.Today, the medical diagnosis and treatment techniques with the continuous progress of science and technology has been tremendous development.For respiratory disease, the majority of patients with ventilator treatment of respiratory diseases to bring good news.Paper designed a remote control system dedicated ventilator for COPD.System consists of ventilator system,3G communication systems, man-machine interface, and information transmission modules.Through3G communication system interactive interface and ventilator.Ventilator-associated mode’s parameters are setting in the human-computer interaction interface, the work carried out by the3G communication parameters ventilator settings, indirect control of the state of the ventilator. When using a breathing machine for treatment of patients with COPD, Physicians need to re-adjust the settings parameters and breathing mode after COPD condition changes.Develop COPD special breathing machine remote control system is based on historical data and the patient’s treatment status, adjust the remote ventilator mode and its parameters, to facilitate subsequent treatment of disease.The main research content and methods papers include:1)Through to be modified the existing Xin Song band bi-level ventilator.lt can be Modify ventilator setting parameters mode and its associated operating parameters through external.2)Design of man-machine interface, based on the ventilator protocol, using VB language design COPD special breathing machine remote control system of interactive interface.3)Debugging3G module, to determine their means of communication for SMS communication.4)Design information transmission module,by STC12C5A60S2as the master chip, RS232interface for communication interface information transmission module.The3G communication module to connect with respiratory machines, as well as3G module and the host computer,interact with each other, reaches remote communications, control purposes ventilator.5)Finally, the above modules connected, test its remote control. Experiments show that through the3G module can be remote controlled ventilator.In the paper the remote control system of COPD specific ventilator design has advantages that:1)Installation is simple, interactive interface is simple and can be installed directly on the computer,And as long as there is cell phone signal, you can connect a breathing machine, insert the SIM card to communicate.2)High reliability, COPD special breathing machine remotely control implementation is one to one communication, without worrying about the introduction of other data interference, high reliability of data.3)Use interactive interface, you can clearly see the current operating state of the ventilator, physician queries, and modify parameters.
