Abstract

Updated September 19, 2017. The automatic surgical vacuum and fluid control system consists of an air flow sensor and meter in the form of an air tube connected to a flow control valve operated by a reversible DC motor. Data from the air flow sensor is transmitted to an electronic circuit board for processing along with user input via a rotary switch. Commands are then sent to the reversible DC motor to control the vacuum and fluid flow in the system as needed, and various operating parameters are displayed on an LCD screen. When the automatic surgical vacuum and fluid control system is connected to a traditional vacuum control system via a safety valve, the user can select either automatic or traditional operation as required. ---------------------------------------------------------------------------------------------------- Updated October 7, 2016. The automatic surgical vacuum and fluid control system consists of an air flow sensor and meter in the form of an air tube connected to a flow control valve operated by a reversible DC motor. Data from the air flow sensor... The airflow rate is measured and transmitted to an electronic circuit board for processing with values entered by the user via a rotary switch. A command is then sent to a reversible DC motor to control the suction force of air and fluid in the system as needed. Various operating parameters are also displayed on the LCD screen. When connecting the automatic surgical air and fluid control system to a conventional vacuum control system via a safety valve, the user can select either automatic or conventional operation as required. --------------------------- The automatic surgical air and fluid control system consists of an air flow sensor, which is connected to an air flow control valve. The air passage of the valve is controlled by a reversible DC motor via a toyron tubing. Data from the air flow sensor is transmitted to a microcontroller for comparison and processing with values entered by the user via the rotary switch. It is made using a potentiometer, which sets the user's desired airflow rate into the system. Values from the airflow sensor and the adjustable rotary switch are sent to a microcontroller and displayed on an LCD screen. The microcontroller processes the data from these two sources and sends commands to a reversible DC motor. When the motor rotates in the specified direction, it controls the width of the airflow valve, widening or narrowing it to control the suction and fluid flow in the system as needed. When an automatic surgical vacuum and fluid control device is connected to a complete vacuum control system, the Toyoron hose from the vacuum source is connected to one end of a safety valve, which is a three-way splitter with directional valves. The other two ends are connected to the automatic surgical vacuum and fluid control device and a traditional manual airflow control valve. Under normal operation, the valve is rotated to connect and control the vacuum and fluid flow with the automatic surgical vacuum and fluid control device. However, if the automatic surgical vacuum and fluid control device malfunctions, the system will automatically adjust the flow rate. Users can adjust the safety valve to operate via the traditional manual airflow control valve, allowing the automatic suction and fluid control system in surgical procedures to continue functioning even in the event of malfunction.
