Abstract:
Objective To develop a miniature negative pressure aspirator with easy operation,stable negative pressure,low weight,small volume and high portability.Methods A double-faced printed circuit board with a size of 6 cm×4 cm×1 cm was manufactured with the functions of regulating the current and DC/AC conversion.DC vacuum pump and Panasonic li-ion battery pack were used to generate the desired pressure between-0.017 and-0.060 MPa,and mechanically-driven deformation vacuum gauge was involved in manufacturing the aspirator.Two sizes (150 and 200 ml) of drainage bottles were made of medical silica gel.Results The aspirator facilitated negative-pressure therapy when the patient was walking or discharged,which decreased the hospital cost and stay.Conclusion The aspirator gains advantages in stable negative pressure,low power consumption,easy operation and high safety,and thus is worthy promoting clinically.
