Computerized Medication Carts: Medication errors are still possible.

Computerized medication cart

1982 case. Penicillin cartridge and reusable injector syringe for deep muscular injection: Vascular injection can clog the vessel with the thick medication; ischemic tissue damage; transverse myelitis; paralysis.

Tubex syringe

Test fixture for controlled pull of plunger to test the visibility of blood in the thick white drug.

No human blood seen in cartridge after plunger pulled (aspirated): No indication that needle is accidentally in a blood vessel; needle/cartridge design flaw (from 36years ago).
