Abstract
A luer lock connection device for medical use, for example, in continuous ambulatory peritoneal dialysis in which a solution container is coupled via flexible tubing to a patient'"'"'s tube that communicates with the patient'"'"'s peritoneal cavity.
The luer lock connection device includes a cooperating male luer lock connector and a female luer lock connector, with visual indicating means provided to indicate that the male and female connectors are assembled properly for use when they are in a predetermined relationship. The male and female luer lock connectors are structured to provide a double sealing arrangement for aiding in maintaining an uncontaminated connection.
