Embodiment 1

[0171] figure 1 It is a schematic diagram showing the structure of the ultrasonic rapid dehydration system for pathological tissues of the present invention, and a part is shown in cross section. In this embodiment, the ultrasonic rapid dehydration system for the pathological tissue includes: a dehydration cylinder 1, in which a special dehydration reagent 3 is stored and the tissue block 4 is submerged in the embedding cassette; an ultrasonic system 9, which provides ultrasonic mechanical vibration to the dehydration cylinder 1; The system 8, based on the feedback signal of the liquid temperature sensor 10, is controlled by the logical relations in the control system 8 and each executive component is controlled: the cooling system is composed of a liquid cooling system 15 and a heat dissipation cooling fan 37, and is controlled by controlling the liquid cooling system 15 , the opening and disconnection of the heat dissipation cooling fan 37 realizes the temperature control; t...

Embodiment 2

[0223] Figure 10 is to use figure 1 Flow chart of an example of the dehydration process of the ultrasonic rapid dehydration system for pathological tissue.

[0224] In the above-mentioned embodiment 2, it is explained that S1: putting into the embedding cassette containing tissue block process, S2: special dehydration reagent addition process, S3: special dehydration reagent preheating process, S4: dehydration process (T1-0.5<T <T2+0.5), S5: end the dehydration process, but the dehydration process of the present invention is not limited thereto. In particular, as long as there are S3: dedicated dehydration reagent preheating process, S4: dehydration process (T1-0.5<T<T2+0.5), the presence or absence of other processes, and the additional reduction of other processes, the contents of these processes can be changed appropriately. That is, as long as it is included in the S3: special dehydration reagent preheating process, if the temperature is too low, use the retort heater ...

Abstract

The invention provides an ultrasonic rapid dewatering system for pathological tissues. The ultrasonic rapid dewatering system comprises an ultrasonic system, a dewatering cylinder, a reagent adding mechanism, a waste-liquid recovery mechanism, a dewatering cylinder heater, a liquid cooling system, a condensing and returning device and a control system, wherein the ultrasonic system acts on the bottom part of the dewatering cylinder; the reagent adding mechanism is connected with the upper part of the dewatering cylinder; the waste-liquid recovery mechanism is communicated with the bottom part of the dewatering cylinder; the dewatering cylinder heater is arranged at the periphery of the dewatering cylinder; the liquid cooling system is arranged at the periphery of the dewatering cylinder; the condensing and returning device is positioned above the dewatering cylinder; the control system is used for controlling the ultrasonic system, the dewatering cylinder heater, the liquid cooling system and the condensing and returning device. The use method comprises the following steps: firstly precooling the dewatering cylinder, putting an embedding box inside, adding a special dewatering reagent, heating, starting the ultrasonic system for fixation, dewatering, performing transparence treatment and taking out. The ultrasonic rapid dewatering system and the use method provided by the invention have the advantages that rapid fixation, dewatering and transparence treatment on tissue blocks are realized, simultaneously the quality of sliced tissues is guaranteed, and the healthy and environmental-friendly effects are achieved.

Description

technical field [0001] The invention relates to the field of pathological tissue detection, in particular to an ultrasonic rapid dehydration system for pathological tissue and a usage method. Background technique [0002] Biological tissue will quickly decay after leaving the living body, losing its original normal structure, and cannot be used for tissue observation and research. Paraffin-fixed tissues are preserved and used for section observation, which is the most widely used method in biological histology. Through paraffin sectioning, the morphological structure of cells and biological tissues can be observed under a microscope. It is the main method for studying, observing and judging the morphological changes of cells and tissues and the distribution of biological macromolecules in biology, pathology and forensic science. To observe the tissue in vitro, it needs to be fixed, dehydrated, transparent, dehydrated, embedded, sectioned and stained to achieve long-term pre...
