Exhibit 31.1

         Chief Executive Officer Certification

         I, Emile A. Battat, certify that:

         1. I have  reviewed  this  Quarterly  Report  on Form  10-Q  of  Atrion
         Corporation;

         2. Based on my  knowledge,  this  report  does not  contain  any untrue
         statement of a material fact or omit to state a material fact necessary
         to make the statements made, in light of the circumstances  under which
         such  statements  were made, not misleading  with respect to the period
         covered by this report;

         3. Based on my knowledge, the financial statements, and other financial
         information  included in this  report,  fairly  present in all material
         respects the financial condition,  results of operations and cash flows
         of the  registrant  as of,  and  for,  the  periods  presented  in this
         quarterly report;

         4. The registrant's  other certifying  officer(s) and I are responsible
         for establishing and maintaining disclosure controls and procedures (as
         defined  in  Exchange  Act  Rules  13a-15(e)  and  15d-15(e))  for  the
         registrant and we have:

         a) Designed such  disclosure  controls and  procedures,  or caused such
         disclosure   controls  and   procedures   to  be  designed   under  our
         supervision,  to  ensure  that  material  information  relating  to the
         registrant,  including its consolidated subsidiaries,  is made known to
         us by others within those entities,  particularly  during the period in
         which this report is being prepared;

         b) Evaluated the effectiveness of the registrant's  disclosure controls
         and procedures and presented in this report our  conclusions  about the
         effectiveness of the disclosure controls and procedures,  as of the end
         of the period covered by this report based on such evaluation; and

         c)  Disclosed  in this report any change in the  registrant's  internal
         control  over  the  financial   reporting  that  occurred   during  the
         registrant's  most  recent  fiscal  quarter  (the  registrant's  fourth
         quarter in the case of an annual report) that has materially  affected,
         or is reasonably likely to materially affect, the registrant's internal
         control over financial reporting; and

         5. The  registrant's  other  certifying  officer and I have  disclosed,
         based on our most recent  evaluation of internal control over financial
         reporting,  to the registrant's auditors and the audit committee of the
         registrant's  board of directors (or persons  performing the equivalent
         functions):

         a) All significant  deficiencies and material  weaknesses in the design
         or operation of internal  control over  financial  reporting  which are
         reasonably  likely to  adversely  affect  the  registrant's  ability to
         record, process, summarize and report financial information; and

                                       15

<PAGE>

         b) Any fraud,  whether or not  material,  that  involves  management or
         other  employees  who  have a  significant  role  in  the  registrant's
         internal control over financial reporting.
