Finger pad

The actuator contains the final orifice and a finger pad or mechanical linkage for on—off control. The spray pattern is largely affected by the constmction of the actuator, particularly by the chamber preceding the orifice. Actuators are often termed mechanical breakup and nonmechanical breakup depending upon the complexity of this chamber. Mechanical breakup actuators are of more expensive two-piece constmction. Actuators are usually molded from polyethylene or polypropylene the breakup insert may be almost any material, including metal. 

A light touch of the skin by the finger pad, for example, to assess skin smoothness, brings into play a multitude of physical, chemical, neuro-physiological, and cognitive processes. 

The Reflotron system consists of the reagent carrier, reflection photometer and an air displacement pipette or applicator. It is easy to operate. The required blood sample is obtained by puncturing the finger pad or ear lobe with... 

An air displacement pipette (Fig. 33) and an applicator (Fig. 34) are used with a nominal volume of 32 pi. It is not necessary to rinse the tip of the pipette, since it is entirely impractical (and in fact impossible) to rinse the tip when drawing blood from the finger pad or ear lobe. However, the test strip must... 

Use tongs or finger pads to prevent the uptake of moisture by dried objects.

Both the primary point and the endpoint are pressed simultaneously using a few ounces of pressure by a finger pad on each hand. The physician can identify the primary point as the "first point" for the patient. The pressure is enough to elicit the... 

The naUs should be inspected for clubbing, color (abnormal paUor or cyanosis), or infection around the edges (paronychia). Calluses of the finger pads should be noted. Any atrophy of the thenar or hypothenar areas should be noted. 

Most significant in the upper extremity is an infection of the hand because this can spread rapidly through the open network of fascia and tunnels in the compartments of the hand. A localized infection of the tuft of the finger pad is known as afelon. Infections around the nails are...
