Abstract

The invention discloses an air tightness detection device and an air tightness detection method for a Westergren erythrocyte sedimentation rate analyzer channel. The air tightness detection device comprises an air tightness detector, a sealing component and an air guide channel formed on a rotating disc of a Westergren erythrocyte sedimentation rate analyzer; the air tightness detector is connected with the air guide channel, and the sealing component is used for blocking the outlet end of a blood distribution connector of the Westergren erythrocyte sedimentation rate analyzer; the sealing component is connected with a first driving device so as to block the outlet end by moving in the axial direction of the blood distribution connector; the air guide channel and the blood distribution connector are communicated and can form a closed detection cavity. The detection method is based on the device, the airtightness detector, the sealing component and the air guide channel are arranged, the sealable detection cavity is formed, ventilation, air pressure measurement and other operations are conducted on the detection cavity, and whether the air tightness of the installation position of the blood distribution connector reaches the standard or not is judged; the rotating disc can rotate, different blood distribution connectors can be switched to be connected with the air guide channel through rotation of the rotating disc, and then the air tightness of different detection cavities is measured.

Description

technical field [0001] The invention relates to the field of detection of erythrocyte sedimentation rate by the Widman method, in particular to an air tightness detection device and an air tightness detection method for a channel of a Widman method erythrocyte sedimentation instrument. Background technique [0002] The Widman's method erythrocyte sedimentation rate detector is equipped with a fixed plate, one side of the fixed plate is provided with a plurality of blood distribution joints in the circumferential direction, and the other side is in contact with the rotating plate, and the rotating plate is provided with a blood supply channel, and the rotating plate can rotate relative to the fixed plate to Switch different blood distribution joints to connect with the blood supply channel, and then perform the next step of inspection and other operations. However, the connection between the blood distribution joint and the fixed plate is prone to leakage after long-term use,...
