Description

Technical Field

[0001] The present invention relates to the technical field of pathological analysis, and specifically provides an automatic tissue decalcifier. Background Art

[0002] In pathology, examination methods such as bone marrow biopsy (BMB) are important bases for disease diagnosis and treatment. As a hard tissue, bone marrow tissue contains a large amount of mineralized substances, which causes great difficulties in sectioning. Therefore, during the embedding and section preparation of tissue specimens, decalcification treatment is required to perform routine section preparation;

[0003] During the decalcification process of tissue samples, usually, staff members put the tissue samples into the interior of the decalcification equipment, and then add an appropriate decalcifying solution according to the actual situation. The amount of the decalcifying solution should be sufficient, generally 20 - 30 times the volume of the specimen, and the solution should be frequently replaced with a new one. During the decalcification process, a stirring device is used to stir the tissue samples and the decalcifying solution to increase the decalcification efficiency. After decalcification is completed, finally, the staff members take out the decalcified tissue samples;

[0004] When decalcifying tissue samples, in order to ensure the decalcification effect, the decalcifying solution needs to be replaced regularly. Existing ultrasonic decalcification equipment can improve the decalcification efficiency by using ultrasound, but during the processing, manual replacement of the decalcifying reagent and subsequent post - decalcification processing are required, and the staff cannot be completely liberated. Currently, there is another type of decalcification equipment that stirs and heats to stir the tissue samples and the decalcifying solution, which can increase the decalcification efficiency. However, when decalcifying tissues with difficult - to - penetrate structures or when the concentration of the decalcifying solution is low, this method has relatively little effect, and the improvement of the decalcification efficiency is limited; increasing the decalcification efficiency by the method of heating + stirring, but heat itself has a risk of damaging the tissue. For this reason, we propose an automatic tissue decalcifier. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the existing technical defects, and provide an automatic tissue decalcifier that can complete the decalcification process fully automatically, with the whole process unattended, effectively protecting the safety of the samples, improving the decalcification efficiency of the samples, enhancing the work efficiency of the staff while reducing the work intensity of the staff. At the same time, the technical solution in the present invention protects the tissue samples, the ultrasonic cylinder and its internal components from damage by ultrasonic high temperature, and effectively solves the problem that the instrument life is reduced due to long - term uninterrupted operation of the ultrasonic cylinder. It can effectively solve the problems in the background art.

The ultrasonic cylinders are connected to the steering solenoid valves, the steering solenoid valves are connected to the drainage pumps, and the waste liquid bottles are connected to the drainage pumps. The input ends of the steering solenoid valves and the drainage pumps are electrically connected to the output ends of the PLC controller, so that the waste liquid generated during the sample decalcification process can be collected.

[0012] Through the combined operation of the liquid extraction and drainage system with microcomputer controllers such as PLC and HMI, the staff can set the tissue decalcification treatment program steps through the HMI human-computer interaction, and realize the programmed automatic addition or evacuation of reagents for sample treatment by the instrument.

[0013] Furthermore, it also includes a filter tube, a filter fan and a protective cover. The filter tube is arranged at the upper end of the partition plate, the filter tube is located on the right side of the filter, the filter fan is arranged at the front side inside the filter tube, the protective cover is arranged at the front end of the filter fan, and the input end of the filter fan is electrically connected to the output end of the PLC controller, ensuring that the reagent aerosol caused by the volatile reagents during the tissue treatment is filtered in time to protect the environment and the health and safety of the staff.

[0014] Furthermore, it also includes a filter net, and the filter net is respectively inserted into the slots arranged in the middle of the upper end of the filter tube, which can filter the harmful aerosol particles caused by the volatile reagents during the tissue treatment.

[0018] 1. The staff sets the corresponding decalcification program through the HMI, and the HMI transmits the set decalcification program parameters (or related control parameters) to the PLC controller for execution. Then, through the regulation of the PLC controller, the liquid extraction pump aspirates the decalcifying solution and adds it into the ultrasonic cylinder. Then, the ultrasonic waves generated by the ultrasonic vibrator intensify the molecular movement, making the decalcification process more uniform, further improving the decalcification efficiency. The whole process is unattended, and the automatic tissue decalcifier can complete the decalcification work fully automatically.

[0019] 2. When the temperature inside the ultrasonic cylinder is higher than the set value, through the regulation of the PLC controller, the first air-cooling fan and the second air-cooling fan start to operate. The heat dissipation aluminum fins absorb the temperature inside the ultrasonic cylinder and conduct it to the surface of the heat dissipation aluminum fins. Then, the air flow generated by the rotation of the first air-cooling fan and the second air-cooling fan cools down the heat dissipation aluminum fins, thereby reducing the temperature inside the ultrasonic cylinder. By maintaining the temperature stability inside the ultrasonic cylinder, air-cooling heat dissipation effectively protects the sample tissue while accelerating decalcification. This not only shortens the decalcification time, but also improves the decalcification effect, and at the same time effectively protects the ultrasonic generator and its internal components from high-temperature damage.

[0020] 3. During the process of decalcification work, through the regulation of the PLC controller, the solenoid valve and the steering solenoid valve start to open, and the drainage pump starts to operate. The waste liquid generated by decalcification in the ultrasonic cylinder enters the inside of the drainage pump through the steering solenoid valve, and finally enters the inside of the waste liquid bottle through the drainage pump, thereby collecting the waste liquid generated by decalcification. The liquid extraction pump starts to operate, and the decalcifying solution inside the reagent bottle enters the inside of the filter through the solenoid valve for filtration. After filtration, the decalcifying solution enters the inside of the ultrasonic cylinder through the liquid extraction pump, thereby realizing the automatic replacement of the decalcification treatment reagent in the decalcification step by the instrument, reducing human intervention, reducing the labor intensity of the staff while improving work efficiency, and protecting the safety of the sample.

[0037] Among them: it also includes an HMI 7, which is arranged on the upper side of the front end of the housing 1. The HMI 7 is electrically connected to the PLC controller 5 in a two-way manner. The staff sets the corresponding decalcification program through the HMI 7, and the HMI 7 transmits the set decalcification program (or related control parameters) to the PLC controller 5 for execution.

[0038] Among them: it also includes heat dissipation aluminum fins 10 and a first air-cooled fan 11.

The input ends of the first air-cooled fan 11 and the second air-cooled fan 23 are electrically connected to the output end of the PLC controller 5. When the temperature inside the ultrasonic cylinder 9 is higher than the set value, through the regulation of the PLC controller 5, the first air-cooled fan 11 and the second air-cooled fan 23 start to operate. The heat dissipation aluminum fins 10 absorb the temperature inside the ultrasonic cylinder 9 and conduct it to the surface of the heat dissipation aluminum fins 10. Then, the air flow generated by the rotation of the first air-cooled fan 11 and the second air-cooled fan 23 cools the heat dissipation aluminum fins 10, thereby reducing the temperature inside the ultrasonic cylinder 9.

[0039] The working principle of an automatic tissue decalcifier provided by the present invention is as follows: During the operation of the automatic tissue decalcifier, tissue samples are successively placed into the interior of the ultrasonic cylinder 9. Then, through the regulation of the control switch 2, the PLC controller 5 starts to operate. Subsequently, the staff sets the corresponding decalcification program through the HMI 7, and the HMI 7 transmits the set decalcification program (or related control parameters) to the PLC controller 5 for execution. The relays provided inside the automatic tissue decalcifier play roles such as automatic regulation and safety protection in the circuit. Then, through the regulation of the PLC controller 5, the solenoid valve 13 is opened, and the liquid extraction pump 16 starts to operate. The decalcifying solution inside the reagent bottle 12 enters the interior of the filter 14 through the solenoid valve 13 for filtration. After filtration, the decalcifying solution enters the interior of the ultrasonic cylinder 9 through the liquid extraction pump 16. Then, through the regulation of the PLC controller 5, the ultrasonic controller 6 starts to operate. The ultrasonic controller 6 adjusts the vibration amplitude of the ultrasonic vibrator 8. The ultrasonic vibrator 8 converts electrical energy into mechanical energy (acoustic wave vibration) through the piezoelectric effect. This vibration propagates in the form of ultrasonic waves. Then, the ultrasonic waves generated by the ultrasonic vibrator 8 intensify the molecular movement, increase the chance of molecular collisions, thereby increasing the average molecular energy, reducing the activation energy required for the reaction, and increasing the chemical reaction rate, making the decalcification process more uniform and efficient. During the decalcification process, the temperature sensor inside the ultrasonic cylinder 9 continuously detects the temperature inside the ultrasonic cylinder 9, and the temperature sensor transmits the detected data to the PLC controller 5 in real time. When the temperature inside the ultrasonic cylinder 9 is higher than the set value, through the regulation of the PLC controller 5, the air-cooling fan one 11 and the air-cooling fan two 23 start to operate. The heat dissipation aluminum sheet 10 absorbs the temperature inside the ultrasonic cylinder 9 and conducts it to the surface of the heat dissipation aluminum sheet 10. Then, the air flow generated by the rotation of the air-cooling fan one 11 and the air-cooling fan two 23 cools the heat dissipation aluminum sheet 10, thereby reducing the temperature inside the ultrasonic cylinder 9. During the decalcification operation, through the regulation of the PLC controller 5, the solenoid valve 13 and the steering solenoid valve 15 are opened, and the liquid drainage pump 17 starts to operate. The waste liquid generated by decalcification in the ultrasonic cylinder 9 enters the interior of the liquid drainage pump 17 through the steering solenoid valve 15 and finally enters the interior of the waste liquid bottle 18 through the liquid drainage pump 17, thereby collecting the waste liquid generated by decalcification. The liquid extraction pump 16 starts to operate. The decalcifying solution inside the reagent bottle 12 enters the interior of the filter 14 through the solenoid valve 13 for filtration. After filtration, the decalcifying solution enters the interior of the ultrasonic cylinder 9 through the liquid extraction pump 16, thereby automatically replacing the decalcifying solution. After decalcification is completed, finally, the staff can take out the decalcified tissue samples.
