Abstract
A pneumatic circuit and other components are provided for the operation of a medical device. The pneumatic circuit provides controlled pressurized air to a medical device for use during a medical procedure.
Claims20
A pneumatic circuit comprising:
- a compressor;
- a pressurized gas conduit coupled to the compressor and having an exit port;
- a gas-permeable absorber coupled to the exit port, wherein the absorber is used to collect moisture in the pneumatic circuit and dissipate the moisture into the atmosphere through the absorber.
A medical device comprising:
- a biopsy device having a pneumatic motor;
- a compressor coupled to the pneumatic motor for energizing the pneumatic motor;
- a pressurized gas conduit coupled to the compressor, the conduit having an exit port;
- a gas-permeable absorber mounted on the exit port, the absorber absorbing and dissipating moisture contained in the pressurized gas as the
- pressurized gas passes through the absorber;
- and
- a cabinet housing the compressor, gas conduit, exit port, and absorber.
4 more elements
A method of removing moisture from a compressed gas system housed in a cabinet, the method comprising the steps of:
- compressing the gas with a compressor;
- directing the compressed gas through a conduit to an exit port;
- directing the compressed gas through the exit port and through
- a gas-permeable absorber connected to the exit port;
- and
- using the absorber to collect moisture from the compressed gas and dissipate the moisture into the atmosphere inside the cabinet.
