Abstract:
There are some problems such as difficulty of pressure control, inconvenience of use and carry, congested easily and dredged hardly in clinical application of vacuum extractor in common use. For solving the above problems, researchers have designed a new portable and pressure stabilized abdominal drainage system which was composed of integral double spherical aspirator and separated double cannula. The new apparatus has achieved good effects in drainage which is suitable for not only rescuing of abdominal trauma and war wound, but also abdominal surgery that manifested as sucking safe and effective, using easily and convenient, that was verified by testing.
