ABSTRACT:
An apparatus for vertically aligning a given point on a pressure transducer unit with a desired point an a patient, the apparatus comprising: (a) a light source; (b) a housing adapted to contain the light source; (c) at least one leveling tube having a leveling axis that is substantially parallel to the light beam, the leveling tube comprising (i) a closed transparent envelope containing a liquid and a bubble of gas, and (ii) lines formed on the envelope, where the leveling axis is substantially horizontally aligned when the bubble of gas is located between the two lines; (d) an indicating mark formed on the housing means, where the beam of light is vertically aligned with the given point on the transducer unit when the indicating means is vertically aligned with the given point on the transducer unit; and (e) a locking system for selectively locking the housing means to prevent movement thereof relative to the transducer unit when the beam of light is both horizontally aligned and vertically aligned with the given point on the transducer unit. To vertically align the given point with the desired point, one of the transducer unit and the patient are vertically displaced relative to the other until the light source causes light to reflect off of the patient at the desired point.
