Rapid pathological tissue dehydrating machine

Abstract

The invention relates to equipment for making biological tissue specimen paraffin sections, in particular to a rapid pathological tissue dehydrating machine. The rapid pathological tissue dehydrating machine comprises a machine box body and an intelligent operating table. A specimen treating box, a paraffin box, a vacuum pump, a plurality of reagent barrels and an ultrasonic generator are arranged in the machine box body, a microwave cavity is formed in the specimen treating box, a microwave source is connected to the microwave cavity, and the specimen treating box is connected with the paraffin box, the reagent barrels and the vacuum pump through pipeline assemblies. The rapid pathological tissue dehydrating machine integrates microwave treatment, ultrasonic treatment and vacuum treatment and cooperates with special reagents, traditional tissue treating time can be shortened to 20 min-3 h from 16 h-22 h, the procedures of immobilizing, dehydrating, transparentizing, wax impregnating, section making and diagnosing can be completed within 2 h after a small specimen is delivered, pathological diagnosis can be made within 32 h after a radical cure specimen is delivered, time of waiting for disease diagnosis is shortened for patients, anxiety is relieved, and especially time is saved for patients needing to receive special treatment such as surgery or targeted therapy; the length of stay is reduced for patients, and hospitalization expenses are reduced; meanwhile, the economic benefits of hospitals are increased.

Description

technical field [0001] The invention relates to a device for making paraffin slices of biological tissue samples, in particular to a fast pathological tissue dehydrator. Background technique [0002] At present, frozen section technology and other rapid diagnostic techniques are widely used at home and abroad to solve the problem of pathological diagnosis in surgery. Although the frozen section technique is still the first choice, it often has disadvantages such as too thick slices, blurred tissue cell morphology, ice crystal artifacts, and sliced ​​specimens cannot be preserved for a long time. In addition, the traditional rapid paraffin section method related to non-frozen section technology mainly uses alcohol lamps, electric furnaces or water baths to directly heat the tissues to shorten the time for tissue fixation, dehydration, transparency and wax immersion, but the disadvantages of this method are The volume of tissue specimens is required to be too small, the time ...

AI Technical Summary

Problems solved by technology

Adopt this device to have the following defects: 1. in the sample processing box, the inside of the sample processing box is heated by a heater, although adopting this kind of structure can realize the basic requirements of heating, but adopting this kind of heating method has weak penetrating ability and cannot It takes a long time to achieve a good drying effect; 2. There are four reagent pots, which not only prolongs the dehydration time of pathological tissues, but also increases the consumption of reagents due to the large number of reagent pots; 3. Due to the There is no heating device in the reserve wax box, reagent pot and cleaning pot, so the paraffin and reagents flowing into the specimen processing box are all in the normal temperature state, which needs to be heated from the normal temperature state, which will lead to longer heating time, thus prolonging the processing time. Dehydration time of pathological tissue; 4. Neither the dehydration solution nor the cleaning solution can be reused
