                Atrion Reports Third Quarter Results;
                     Diluted EPS Increased by 30%

    ALLEN, Texas--(BUSINESS WIRE)--Oct. 28, 2004--Atrion Corporation
(Nasdaq:ATRI) today announced that for the third quarter of 2004
diluted earnings per share were up 30% compared to the results for the
third quarter of 2003. Revenues in the third quarter increased by 4%
from the same prior-year period.
    Commenting on the Company's results, Emile A. Battat, Chairman and
CEO, said, "Compared to the same quarter last year, sales in three of
our major product areas, cardiovascular, fluid delivery, and other
products, were significantly higher. As in the two prior quarters of
this year, our growth in these areas was masked by declines in
ophthalmology sales. The overall sales increase coupled with a higher
gross profit margin percentage resulted in a 20% increase in operating
income for the quarter over the comparable prior-year period. Our
strong operating results, coupled with a lower effective tax rate in
the current-year quarter, pushed our diluted earnings per share to a
new quarterly record for the Company."
    Atrion's revenues for the quarter ended Sept. 30, 2004 were
$16,704,000 compared with $16,117,000 for the same period in 2003. On
a diluted per share basis, net income for the period increased to $.95
as compared to $.73 in the same quarter of last year.
    Revenues for the first nine months of 2004 increased 4% to
$49,910,000 from $48,013,000 for the same period in 2003. Net income
for the first nine months of 2004 was $2.52 per diluted share versus
$2.07 in 2003, with gains from discontinued operations of $.09 per
share in both periods.
    Additionally, the Company reported that Filtertek Inc., a
subsidiary of ESCO Technologies Inc., has claimed that swabable valves
manufactured by a Company subsidiary, Halkey-Roberts Corporation,
infringe on Filteterk's patent. The parties are now engaged in
litigation before the United States District Court in Tampa, Fla.
Filtertek is seeking, among other things, damages and injunctive
relief. The Company believes that swabable valves represent a major
growth opportunity, and intends to vigorously defend its intellectual
property. Halkey-Roberts has asked the court to declare that
Filtertek's claims are without merit. Halkey-Roberts has also asked
the court to invalidate Filtertek's patent.
    Atrion Corporation designs, develops, manufactures, sells and
distributes products and components primarily to medical markets
worldwide.
