Description

An ultrasonic vibration cleaning tank

technical field

The invention relates to the technical field of immunochemical analysis, in particular to an ultrasonic vibration cleaning tank for a fully automatic tubular chemical analyzer.

Background technique

Immunodiagnosis is the application of the principles, techniques and methods of immunology to diagnose various diseases and determine the immune status. In medicine, it is an important method to determine the etiology and lesion site of a disease, or to determine whether the basal immune status is normal. The traditionally used radioimmunoassay technique has been gradually replaced by the emerging chemiluminescence immunoassay technique due to its complex manual operation, long reaction time, and strong environmental pollution, which has significantly improved the work efficiency of immunodiagnosis. The utility model application with the application number 200920160359.X and the application name "semi-automatic tubular chemiluminescence immunoassay analyzer" discloses a chemical instrument for immunoassay. The analyzer includes a turntable system, a sample adding system, a chemical There are five parts: luminescence detection system, control system and software system. The turntable system is driven by a servo motor through a two-stage deceleration device to rotate the turntable; the sample adding system adds samples to the test tubes on the turntable through the sample loading arm; the chemiluminescence detection system uses an optical fiber probe Test samples; the control system uses the chip maga as a microprocessor; the software system sends instructions to the lower computer to make the lower computer perform corresponding actions. From the above analysis, it can be seen that the analyzer does not have a cleaning system for cleaning the needle group, and the cleaning of the needle group must be done manually. The application number is 201110060474.1, and the invention patent application named "Automatic Chemiluminescence Immunoassay Analyzer" discloses a chemical immunoassay analyzer with a high degree of automation. The instrument includes a control system, a reaction cup feeding system, and a three-dimensional mobile sample adding Modules, pump sets, sample areas and reagent areas, where the cuvette feeding system includes palletizing modules, transfer modules, incubation modules, washing modules and measurement chambers, palletizing modules, transfer modules, incubation modules, and washing modules travel according to the cuvettes The routes are arranged in sequence, and its washing module includes a needle group, a lifting mechanism and a constant magnetic field area. When washing, the rack first sends the cuvette to the washing position, and the lifting table moves down to the washing liquid filling position, and the needle group starts to pour into the cuvette. The system liquid is filled inside, and then the needle group sucks away the waste liquid. After repeating the above washing process several times, the lifting platform starts to rise, and the rack moves the cuvette to the entrance of the measurement chamber. It can be seen that the function of the washing module in this application is to clean the unbound immune reagents adsorbed on the surface of the magnetic beads in the cuvette, and there is no cleaning device specially provided for the needle set.

Accompanying drawing 1 is a three-dimensional schematic diagram of the utility model, and accompanying drawing 2 is a structural schematic diagram of the utility model, wherein, 1 is a cleaning tank, 2 is an air blowing pipe fixing plate, 3 is an ultrasonic vibrator, 4 is an air blowing pipe, and 5 is an installation of the air blowing pipe Tube, 6 is an ultrasonic vibration chamber, and 7 is a needle group to be cleaned.

Detailed ways

The utility model will be described in detail below in conjunction with the accompanying drawings. The utility model discloses an ultrasonic vibration cleaning tank, which is specially used for a fully automatic tubular chemical analyzer, and is used to realize thorough cleaning of the needle group to be cleaned. . The cleaning tank includes an ultrasonic cleaning system and a liquid spray system, wherein the ultrasonic cleaning system includes a cleaning tank 1 where the needle group 7 to be cleaned is placed during cleaning and an ultrasonic vibrator 3 that generates ultrasonic vibrations. In order to achieve a good ultrasonic cleaning effect, this The ultrasonic vibrator 3 is fixed in the ultrasonic vibration chamber 6 , and the side wall of the ultrasonic vibration chamber 6 is installed in the bottom tank of the cleaning tank 1 . In this way, when the ultrasonic vibrator 3 vibrates, its vibration will be transmitted to the cleaning tank 1 through the ultrasonic vibration chamber 6 . The liquid spray system includes an air blowing pipe 4, a liquid pump, an air blowing pipe fixing plate 2 for installing the air blowing pipe 4, and an air blowing pipe installation cylinder 5. The air blowing pipe mounting cylinder 5 and the air blowing pipe fixing plate 2 are fixedly installed on the cleaning tank 1 . When the liquid pump is turned on, the cleaning liquid extracted in the liquid pump is sprayed onto the outer wall of the needle group 7 to be cleaned through the air blowing pipe 4 to clean the outer wall.

The method steps for cleaning the needle group to be cleaned by using the cleaning tank include:

1) The cleaning tank 1 is horizontally displaced to the bottom of the needle group 7 to be cleaned, and then the needle group 7 to be cleaned is lowered to a predetermined position;

2) The liquid pump is turned on, and the cleaning liquid is sprayed out from the air blowing pipe 4 to clean the outer wall of the needle group 7 to be cleaned;

3) When the liquid level sensor in the cleaning tank 1 detects that the liquid level has reached the predetermined position, the ultrasonic vibrator 3 is turned on to perform ultrasonic cleaning on the inner and outer walls of the needle group 7 to be cleaned, and the blowing pipe 4 stops spraying when the ultrasonic vibrator 3 is turned on. liquid;

4) After the ultrasonic cleaning time is up, while the liquid suction pump is pumping the waste liquid in the cleaning tank 1, the air blowing pipe 4 sprays liquid to clean the outer wall of the needle group 7 to be cleaned;

5) After the cleaning is completed, the cleaning needle group 7 rises, and the cleaning tank 1 moves back.

Wherein the movement of the cleaning tank 1 is carried out under the drive of the stepping motor.

It can be seen that in this method, the needle group 7 to be cleaned is cleaned three times, followed by cleaning the outer wall by liquid spraying, ultrasonic cleaning by ultrasonic vibration, and cleaning the outer wall by spraying liquid. In conjunction with the three cleaning processes, a stepping motor is specially designed. The movement of the cleaning tank under the drive has the advantages of thorough cleaning and high cleaning efficiency.
