The invention discloses a blood collection apparatus, which comprises a blood collection needle, a hose and an air suction and blood discharge joint. The air suction and blood discharge joint comprises a blood discharge channel, an air suction channel, a blind shaft hole and a vent hole, wherein the blind shaft hole penetrates through the blood discharge channel and the air suction channel in thetransverse direction, and the vent hole communicates with the blind shaft hole; a blood inlet of the blood discharge channel is connected with the hose, a blood discharge needle is arranged at a bloodoutlet of the blood discharge channel, an air suction needle is arranged at one end of the air suction channel, an air suction opening is formed in the other end of the air suction channel, and an axially defined rotary shaft valve is arranged at the position of the blind shaft hole; at the initial position, a rotating shaft part is matched with the blind shaft hole in a sealing mode and blocks the blood discharge channel and the air suction channel; in the blood discharging position, a first passage enables the blood inlet and the blood outlet to communicate, and a second passage enables theair suction needle and the air suction opening to communicate; and in the drip proof position, the blood discharge needle communicates with the vent hole, and the air suction needle communicates withthe air suction opening. The problem of blood dripping in a blood collection process is solved thoroughly, and no blood dripping occurs after each detector takes down the blood collection needle after blood collection. In addition, a full-automatic blood collection instrument comprising the blood collection apparatus is also provided.
Description
