摘要：An improved injection apparatus is disclod comprid of a first motor and a cond motor, each motor having a shaft. First and cond needles are located substantially perpendicular to the first and cond shafts, respectively. When the first and cond shafts rotate, the first and cond needles, respectively, move up and down. The first and cond shaft rotate in opposite directions. The first needle and cond needles can be surrounded by first and cond needle tubes, respectively. The first and cond needle tubes can be mounted to a device housing. The first and cond needles each preferably has a portion that lies inside its needle tube and a portion that lies outside its needle tube. First and cond sources of liquid and first and cond conveying tubes are provided. The first and cond conveying tubes are connected to the first and cond needles, preferably at a side arm inside the respective needle tubes. The first and cond needles are preferably hollow. Preferably liquid flows from the first source of liquid to the first conveying tube then into the hollow first needle. Similar liquid flow occurs for the cond needle. The first and cond conveying tubes are connected to first and cond meters which measure how much liquid is being fed into the first and cond needles from the first and cond liquid sources.
