Abstract
A device (10) and method for cutaneously marking the venous anatomy with an ink. The method comprises selectively locating a portion of the venous anatomy to be marked and coating the skin (20) corresponding to the venous anatomy to be marked with a transmission gel (22). The transmission gel (22) permits a technician utilizing an ultrasound transducer to pinpoint the portion of the venous anatomy to be marked. Device (10) simultaneously clears the transmission gel from the skin (20) corresponding to the portion of the venous anatomy to be marked and marks the open space (24) on the skin (20) with the ink.
Claims14
A device for cutaneously marking the venous anatomy which comprises:
- a plastic encasing having an orifice;
- a housing inside the plastic encasing having an inlet port and an outlet port;
- a channel inside the housing, the channel connecting the inlet port to the outlet port;
- a propellent source having a pressurized gas contained therein, the propellent source being connected to the inlet port;
- a reservoir having a marking fluid contained therein, the marking fluid coming in contact with the pressurized gas at the orifice;
- a switch connected to the channel, the switch being selectively engageable to allow the pressurized gas to pass through the channel to the outlet port, the pressurized gas coming in contact with the marking fluid at the office;
- a piercing needle;
- and
- a lever, the piercing needle entering the propellent source upon engagement of the lever and thereby releasing the pressurized gas into the channel.
A system for cutaneously marking the anatomy with a marking fluid by means of a propellent source comprising:
- an ultrasound transmission gel to coat the skin corresponding to the anatomy to be marked;
- an ultrasound transducer for manipulation over the transmission gel to pinpoint the portion of the anatomy to be marked;
- and
- a device which simultaneously clears the transmission gel from the skin corresponding to the portion of the anatomy to be marked as pinpointed by the ultrasound transducer and marks the skin with the marking fluid.
A system for cutaneously marking the venous anatomy of a human being with a marking fluid in preparation for surgery comprising:
- an ultrasound transmission gel to coat the skin corresponding to the venous anatomy to be marked;
- an ultrasound transducer for manipulation over the transmission gel to pinpoint the portion of the venous anatomy to be marked;
- and
- a device which simultaneously clears the transmission gel by means of a propellent source from the skin corresponding to the portion of the venous anatomy to be marked as pinpointed by the ultrasound transducer and marks the skin with the marking fluid.
