Abstract:
Objective To fulfill the precise control of the liquid flow by a multifunctional medical flowmeter. Methods The flowmeter had a separated structure, and was composed of a liquid pipeline unit and a flow control unit. The flow control unit apprehended a velocity of liquid level changes in the sterile pipeline by ultrasonic sensing technique, and regulated fluid speed by a SCM-controlled electromagnetic valve. Results The requirements for sterile environment were fulfilled by the sterile liquid pipeline, and the flow control unit realized precision control of flow rate and achieved the expected effect. Conclusion The flowmeter has simple structure, low cost, convenient operation and use, can greatly reduce the workload of the nursing staff and the possible health risks, and thus is worthy promoting practically.
