What I do, for a similar use case, is to define values using properties
and then extract these values with a little function I wrote (see
below).  For example,

#+begin_src org
,#+property: myvariable 10
,#+begin_src ... :var v=(esf/get-parameter "myvariable")
... (use v in here)

The esf/get-parameter function is:

#+begin_src emacs-lisp
  (defun esf/get-parameter (p)
    (let ((value (org-entry-get (point) p 'inherit)))
      (message "parameter %s value obtained %s" p value)
      (if value
          (if (string-match-p "^[-+ ]*[[:digit:].]+$" value)
              (string-to-number value)
        (error "Property parameter \"%s\" not known." p))))

I'm sure there are better ways but this is what I have developed
organically over the years...
