Apparatus and method for cleaning lumens of medical devices and lines

摘要

An apparatus includes a counter top sized outer case; first and second electric motors disposed inside of the case. A positive displacement liquid pump with a pulsating output is operatively connected to said first electric motor and has an input and output port. A positive displacement gas pump with a pulsating output is operatively connected to the second electric motor and has an input and output port. A liquid source is fluidly connected to the input port of the liquid pump. The method further includes connecting a medical line or instrument to be cleaned to the output port of the liquid pump and operating the pump until the line or instrument has been cleaned. The line or instrument is then disconnected and connected to the output line of the gas pump. The gas pump is operated until the line or instrument has been cleared of liquid and then disconnected.

主权项

1. An apparatus for cleaning medical lines and instruments comprising:
a. a counter top sized outer case having a front panel; b. a first electric motor disposed inside of said case; c. a second electric motor disposed inside of said case; d. operatively connected to said first electric motor an oil-less, seal-less, ring-less positive displacement liquid pump which has a pulsating output and having a vertically disposed head extending outside of said case; e. input and output port operatively connected to said liquid pump; f. operatively connected to said second electric motor an oil-less, seal-less, ring-less positive displacement gas pump which has a pulsating output; g. input and output port operatively connected to said gas pump; and, h. a first electric switch disposed on said front face of said case and a second electric switch disposed on said front panel of said case, wherein said first switch is selectively operable between a first, second and third position, wherein in said first position electric power is not permitted to pass through said first electric switch, in said second position electric power is permitted to pass to said second electric switch, in said third position electric power is allowed to pass to a foot operated switch which is operably connected to said second electric switch and said second electric switch is selectively operable between a first and a second position wherein in said first position electric power is permitted to flow through said second switch to said first electric motor and in said second position electric power is permitted to flow through said second switch to said second electric motor.
