        Certification**
 
 I,
        Jeffery Strickland, 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 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)) and internal control over financial reporting (as defined in Exchange
        Act Rules 13a – 15(f) and 15d – 15(f)) 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)
        Designed such internal control over
        financial reporting, or caused such internal control over financial reporting
        to
        be designed under our supervision, to provide reasonable assurance regarding
        the
        reliability of financial reporting and the preparation of financial statements
        for external purposes in accordance with generally accepted accounting
        principles; and
 
 c)
        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
 
 d)
        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
 
 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.
