Embodiment Construction

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] like figure 1 As shown, according to a first aspect of the present invention, the present invention provides a cleaning mechanism for a pipette, which includes a main body 1, and the main body 1 is provided with a pipetting needle (steel needle) 6 for accommodating the pipette The cleaning channel 2 has an upper opening 21 for inserting and removing the pipetting needle 6 and a drain port 22 opposite to the upper opening 21 for discharging waste liquid. The cleaning channel 2 is provided with a negative The pressure pipeline joint 3, the negative pressure pipeline joint 3 is connected with the negative pressure mechanism (not shown), when the pipetting needle 6 is cleaned in the cleaning channel 2, the negative pressure mechanism is extracted and removed Liquid hanging on the outer wall of the liquid needle 6 . The liquid hanging on the outer wall of the pipetti...

Abstract

The invention relates to a cleaning mechanism and method for a pipettor, relates to the technical field of medical analysis instruments, and aims to solve the problem of liquid hanging on the outer wall of a pipetting needle. The cleaning mechanism for the pipettor comprises a main body, a cleaning channel used for containing a pipetting needle of the pipettor is arranged in the main body, a washing liquid inlet connector is arranged on the side wall of the cleaning channel, the washing liquid inlet connector is connected with a pump body, and the pump body pumps washing liquid into the cleaning channel through the washing liquid inlet connector. A negative pressure pipeline connector is further arranged on the side wall of the cleaning channel, the negative pressure pipeline connector is connected with a negative pressure mechanism, the negative pressure mechanism pumps away hanging liquid on the outer wall of the pipetting needle through the negative pressure pipeline connector, rapid drying of the outer wall of the pipetting needle can be achieved, and normal movement of the pipetting needle cannot be interfered. And the structure of the cleaning mechanism is simpler and more convenient.

Description

technical field [0001] The invention relates to the technical field of medical analysis instruments, in particular to a cleaning mechanism and method for a pipette. Background technique [0002] Pipettes are important equipment on medical analytical instruments, which are used to transfer samples, reagents, and the like. At present, most analytical instruments use hollow steel needles to transfer liquids, which means that the steel needles must be thoroughly cleaned before each liquid transfer to prevent cross-contamination of reagents or samples. [0003] When using various cleaning liquids to clean the steel needle, the inevitable problem is that the outer wall of the steel needle is seriously hung with liquid. And this hanging liquid will undoubtedly interfere with subsequent pipetting. The solution usually adopted now is to add a cleaning swab (such as the swab for cleaning the sampling needle disclosed in Chinese patent CN101099969A) to the main body of the pipette, s...
