Description

TECHNICAL FIELD

[0001] The utility model belongs to the medical instrument related technical field, concretely relates to a modular cleaning and separating device. BACKGROUND

[0002] At present, the full-automatic chemiluminescence immunoassay analyzer is developed for specific reaction mode and cleaning requirements. For sample adding sequence, sample adding mechanism and action sequence need to be configured according to the sequence. For incubation time, sufficient incubation hole positions are mainly configured. For cleaning mode, the queue type sequence operation is mostly adopted. The queue type sequence operation of cleaning and separating refers to that reaction cups carrying reactants are arranged in turn through a series of predetermined positions, and corresponding operations are carried out at each position. The predetermined positions can be divided into shaking function, magnetization and cleaning and liquid changing according to functions. Taking the cleaning mode of a certain type of full-automatic chemiluminescence immunoassay analyzer as an example, the time for completing each function under the current engineering condition is as follows: magnetization and cleaning and liquid changing: 24 seconds; shaking: 6 seconds - a complete cleaning cycle is 30 seconds. In order to improve the test speed, magnetization and cleaning and liquid changing need to be split at two positions, i.e. pre-magnetization and (magnetization) cleaning and liquid changing positions. Only magnetization is carried out at the pre-magnetization position (for 12 seconds), and a part of the (magnetization) cleaning position (for 6 seconds) supplements the insufficient magnetization, and the latter part of the time (for 6 seconds after the cycle) completes the cleaning and liquid changing functions. The total cleaning and separating process covers 17 cycles. The cleaning and liquid changing described in the place refers to pumping out waste liquid and injecting cleaning liquid for rinsing. The pre-magnetization -> (magnetization) cleaning and liquid changing -> shaking -> pre-magnetization -> (magnetization) cleaning and liquid changing -> shaking -> (magnetization) pre-magnetization -> (magnetization) cleaning and liquid changing -> shaking -> pre-magnetization -> (magnetization) cleaning and liquid changing -> shaking -> pre-magnetization -> (magnetization) cleaning and liquid changing -> shaking -> pre-magnetization -> pumping out waste liquid (only pumping out liquid, not changing liquid), the advantage of the mode is compact structure and relatively simple control logic - queue stepping type.

[0003] However, the time for a single test result is prolonged, because shaking itself can be completed in one cycle, the shaking position has idle time in each cycle, and the process itself needs to be queued and waited after completion, and meanwhile, the mode has poor scalability.
