Without more info, it's hard to determine what you exactly want. All you need to do is pass the variable to the appropriate method.

$dbi = new ...
$mod = new MyModule();
$mod->a_method( $dbi );
....

package MyModule # different file I assume

sub a_method {
    my( $self, $dbi ) = @_;
    $dbi->quote( ... );
}

Granted there are a lot better styles. Depending on how many methods need a database handle, passing it to each method may not be the best practice.
