Abstract
A grip layer formed circumferentially around a substantial portion of a length of an ultrasound probe housing and having a high coefficient of friction. The grip layer enables an administering sonographer to maintain control over the ultrasound probe during transthoracic and other ultrasound imaging procedures while applying minimal gripping force. Furthermore, the grip layer accommodates all ultrasound viewing windows regardless of the position of the patient, the location of the sonographer relative to the patient and whether the sonographer uses a right- or left-handed technique. The grip layer is joined to an inner housing so as to form a gas- and liquid-impermeable seal between the grip layer and inner housing, enabling the ultrasound probe to withstand repeated applications of autoclaving, liquid and chemical disinfecting and other sterilization procedures without compromising the electrical integrity of the probe casing. The grip layer and inner housing form a continuously smooth casing surface that is substantially impenetrable by cleaning solvents, coupling gel or contaminants. The grip layer is preferably a substantially thin, non-compressible, elastomeric coating having …
