Alternatives to the complicated system of lemur locks and bacteria static water. I remember an exchange that had a filter you put on the tip or a needleless syringe for pills. Then squirted it into a regular syringe. It has been awhile so I don't remember exactly. They were flat at the bottom and you sucked the pill water up through the filter into the syringe and you were good to go. I got some dilaudid and want to be safe. It would be easier for me to prepare each injection at the time of use and use single use disposable filters that just attach to the 27g needles I have. Is this possible?
