Medical tricorder, 2369

Medical tricorder TR-580 in 2369

The medical tricorder was a specialized version of the standard Starfleet tricorder. It was equipped with sensors and analysis software tailored for medical diagnostic purposes. They were usually the first tool a Starfleet doctor utilized when assessing a patient's condition. Medical tricorders could function aboard ship in sickbay as well as on away missions. (TOS: "The Man Trap")

Medical tricorders were in use aboard Starfleet vessels as early as the mid-22nd century. In 2153, Doctor Phlox noted that Sim had disassembled Phlox's medical tricorder, when commenting on his aptitude for engineering. (ENT: "Similitude")

Medical tricorders used throughout the years have been essentially similar in design to that of the standard tricorder, with the same available features and interface. The major difference is the addition of a deployable hand scanner. While some standard tricorders also have removable scanners, the medical tricorder's is much more advanced and can provide detailed scans of an entire individual, or give focus to a single area. (TOS: "The Man Trap"; TNG: "When The Bough Breaks")

They could also be used to perform quick multivariate analysis, such as the comparison of several different blood samples. (TOS: "Plato's Stepchildren")

It is not necessary to use the scanner for the tricorder to function. The scanner can be separated from the tricorder, either to feed data to another source (TNG: "Up The Long Ladder") or not be attached to the tricorder at all. (DS9: "Babel")

While the suite of sensors installed on medical tricorders is advanced, it is generally no substitute for the advanced and specialized equipment in a sickbay facility. Although very accurate on the living, it is taught in the first year of Starfleet Medical School that medical tricorders are not as accurate on the dead. (TNG: "Genesis", "All Good Things..."; DS9: "The Passenger")

Although tricorders in general are widely available to starship personnel, medical tricorders are not normally made available to non-medical personnel outside sickbay. Despite this, hypochondriac William Telfer managed to obtain one for his own personal use on the USS Voyager. (VOY: "Good Shepherd")

A medical tricorder could, in certain instances, provide a recommended course of treatment for an individual in hostile terrain. Captain Lisa Cusak followed the advice of her medical tricorder when stranded on a Class L planet to give herself fifteen CCs of tri-ox every four hours to compensated for the excess carbon dioxide in the atmosphere. (DS9: "The Sound of Her Voice")

2258 (AR) tricorder

In 2258 of the alternate reality, the medical tricorder consisted of a scanning rod and handheld feedback monitor. (Star Trek) The following year, the scanner had been redesigned into a white oval-shape reminiscent of the previous monitor, and could be stored inside a normal tricorder. (Star Trek Into Darkness)

Shortly after being activated in 2371 following the disastrous catapulting of the USS Voyager to the Delta Quadrant, The Doctor requested of Harry Kim a tricorder and expressed irritation when Kim handed him a normal tricorder rather than a medical one. (VOY: "Caretaker")

Tricorder imagined by Seven

The model imagined by Seven of Nine

In 2374, Seven of Nine described a medical tricorder she imagined in the following manner: "Duritanium casing. Seven point six centimeters by nine point eight centimeters by three point two centimeters. Alphanumeric display" (VOY: "Retrospect")
