A kind of multichannel slide glass specimen incubating device with heating function
Technical field
The invention belongs to biological sample process field, particularly relate to a kind of multichannel slide glass specimen incubating device with heating function.
Background technology
The whole process of immunohistochemistry needs nearly 30 steps, hatch including: a) dewaxing, aquation, endogenous enzyme blocking-up, cleaning, high-temperature hot reparation, cooling, cleaning, primary antibodie, clean, two resist hatch, clean, synergist is hatched, clean, develop the color, clean, serve as a contrast the steps such as dye, cleaning, dehydration, mounting. Impact by the technical merit between hospital and hospital and operating habit difference, it is difficult to standardization. The efficiency and the reliability that improve sample disposal become the task of top priority.
At present in checkout procedure, reagent pipetting volume sprays application of sample above thin slice, and load position error is big, and reagent covering in section is with randomness, it is difficult to guaranteeing to cover whole section, some specimen do not obtain the covering of reagent and false negative occur. Needing high-temperature heating in sample disposal process, this is to make antigen or pathogen characteristic protein reply step necessary to original shape. Heating requirements reaches the temperature of 80-100 DEG C or higher and maintains 5-40 minute. Most common method is that pressure cooker boils, generally boils and boil or the method such as hot water temperature bath.
But, the container of at present conventional slide glass sample disposal or carrier do not possess and can heat or the resistance to performance being heated. Need in the midway of slide glass sample disposal to transfer in heatable container slide glass specimen to carry out, then need again to transfer on the operating board of room temperature, add complexity and the operating error of operating process.
Realize slide glass specimen to be heated in position processing and just can simplify slide glass specimen processing operation step and be easier to carry out full-automatic operation flow process, meet the requirement of simpler reliable, the higher efficiency of slide glass sample disposal.
Summary of the invention

Adding heat pipe and be embedded in hot plate, hot plate is arranged in heater canister; Add heat pipe to be connected with external power supply, and controlled power and the time of heating by manual or controller; Add heat produced by heat pipe and pass to hot plate; Bay trench bottom or main body are made of metal; During energising, the heating heat pipe of bottom is operationally placed on hot plate, accepts the heat of hot plate to heat the liquid in bay groove.
Further, bay groove is provided with discharge outlet, and heater canister is provided with lower discharge outlet; Upper discharge outlet, lower discharge outlet are carried out discharge opeing by manual operation.
Further, bay groove is provided with discharge outlet, and heater canister is provided with lower discharge outlet; Upper discharge outlet, lower discharge outlet are controlled discharge opeing by electric device (such as electromagnetic valve).
Further, bay groove can arranging string or multiple row cover board support, thus inserting the slide glass assembly that string or multiple row are adjacent to by slide glass cover plate and slide glass, forming array type close arrangement.
Further, a biological sample is at least contained above described slide glass.
Further, the material used is capable of withstanding by higher temperature, is generally possible to tolerance 80oMore than C and indeformable or softening.
Further, described device is provided with the heater of Contiuum type or separate type.
Further, the mode of heating of described hot plate, adopt disjunctor or separate type heating rod, heating plate, Electromagnetic Heating induction system to be heated, or heat container irrigates hot liquid carry out temperature bath heating to adding.
Further, when slide glass sample disposal process needs heat treatment, in bay groove, directly irrigate liquid and be heated, it is not necessary to slide glass specimen being shifted in midway, the process of slide glass specimen from start to finish carries out in a container.
Further, heater canister is provided with a spike; Heater canister is made up of insulation material, plays the effect of insulation.
Relative to prior art, the present invention has the following advantages and technique effect:
Assembly of the invention enables slide glass specimen in the way of setting or oblique angle setting rather than the mode of tiling is placed, it is possible to the array type close structure of multiple rows of multiple row is arranged; Slide glass assembly is when erectting, and the liquid in fine gap will not drain off, it is ensured that the slide glass specimen moment obtains the covering of reagent; Section preparation can directly soak or insert in hot solution and uniformly heat, even if the liquid in gap produces volatilization in heating process also due to capillarity is automatically replenished from the fine slit aperture suction of slide glass component bottom, heating is fully, do not produce the phenomenon dried up, ensure the reproducibility and reliability of hot repair process; In assembly of the invention, all of accessory all uses heat proof material to make, and disjunctor is set or separable heater, as long as perfusion appearance liquid just can be made directly heating in bay groove, slide glass specimen is made from start to finish to carry out in a container in processing procedure.
