Automatic sampling mechanism for blood analyzer in clinical laboratory of hospital

Abstract

The invention discloses an automatic sampling mechanism for a blood analyzer in a clinical laboratory of a hospital. The mechanism comprises two support plates, wherein a placement plate is welded atthe tops of the two support plates; a first rotary hole is formed in the top of the placement plate; a first rotary shaft is rotationally mounted in the first rotary hole; the top of the first rotaryshaft extends above the placement plate; a rotary plate is welded at the top of the first rotary shaft; a plurality of test tube grooves are formed in the top of the rotary plate; test tubes are placed in the test tube grooves; a first mounting groove and a push hole are formed in the sides, close to each other, of the two support plates; a first push rod motor is mounted in the first mounting groove; and a first push plate is welded on an output shaft of the first push rod motor. The mechanism is high in practicability; air-borne pathogenic bacteria contaminated on pipettes are convenient toclear due to movement plates and first ultraviolet disinfection lamps; due to the pipettes and the test tubes, blood in the two test tubes can be sucked at one time; and the sampling speed is effectively increased.

Description

technical field [0001] The invention relates to the technical field of automatic analysis instruments, in particular to an automatic sampling mechanism for a blood analysis instrument in a hospital laboratory. Background technique [0002] At present, most of the sampling mechanisms used in various medical analyzers such as trace element analyzers and biochemical analyzers rely on imports. These imported sampling mechanisms have high operating precision and fast sampling speed, but their structures are relatively complicated, and their prices and maintenance costs are relatively high. High, after searching, the application publication number is CN101982779A, which discloses an automatic sampling mechanism for an analytical instrument, including a frame, on which a first stepping motor, a pipette driving device and a liquid collection box are installed, and the first stepping A turntable is installed on the output shaft of the motor, and several test tube fixing holes are eve...

[0002] At present, most of the sampling mechanisms used in various medical analyzers such as trace element analyzers and biochemical analyzers rely on imports. These imported sampling mechanisms have high operating precision and fast sampling speed, but their structures are relatively complicated, and their prices and maintenance costs are relatively high. High, after searching, the application publication number is CN101982779A, which discloses an automatic sampling mechanism for an analytical instrument, including a frame, on which a first stepping motor, a pipette driving device and a liquid collection box are installed, and the first stepping A turntable is installed on the output shaft of the motor, and several test tube fixing holes are evenly arranged on the edge of the turntable, a suction pipe is arranged on the suction pipe driving device, and the suction pipe is connected to the suction pump through a catheter, and a detection cup transmission device is installed in the liquid collection box. Several detection cups are installed on the detection cup transmission device, and the reagent filling pipe and measuring electrode are arranged above the liquid collection box. Connected to the waste liquid collection tank, it has high operating precision, fast sampling speed, simple structure and low cost, but its complex structure is not convenient for automatic sampling of blood analysis instruments, and it can only be sampled once at a time, which is inefficient Bacteria in the air will contaminate the pipette, which will cause deviations in the analysis results, so we propose an automatic sampling mechanism for blood analysis instruments in the hospital laboratory to solve the above problems
