Portuguese to English Science Medical: Health Care equipment

iT Is a list of equipment, and surgical materials, there is no context... I suspect the author is not a native speaker of English, so this may be a mistake....
"spike without wing, without air inlet, chamber 5,5cm without fluid filter"
"spike withwing, with air inlet, chamber 5,5cm without fluid filter, regulator flow, Y injection site and connector lock and cap"
any ideas??
