Paraffin discharging method for paraffin discharging dropper of tumor tissue automatic opening and closing paraffin block embedding machine

Abstract

The invention relates to a paraffin discharging method for a paraffin discharging dropper of an automatic opening and closing paraffin block embedding machine, which is used for dropping molten liquidparaffin in a paraffin melting box into a paraffin collecting box. The paraffin discharging dropper comprises a paraffin dropping tube cavity, a hinged bottom cover, a linkage pull rod, a temporary paraffin storage box and a high-pressure compressed spring. The paraffin discharging method comprises the following steps: 1, inserting the paraffin dropping tube cavity, and starting paraffin discharging; 2, pulling out the paraffin dropping tube cavity, and pausing paraffin discharging; and 3, replacing the paraffin collecting box, and repeating the step 1 and the step 2 to fill a next paraffin collecting box with the paraffin. The paraffin discharging dropper can automatically discharge paraffin and stop discharging paraffin: the paraffin can be discharged actively after insertion of the paraffin discharging dropper into the paraffin dropping tube cavity, paraffin discharging can be stopped automatically after the paraffin dropping tube cavity is pulled out, and continuous operation of aparaffin melting tube is not affected in a period of stopping the paraffin discharging, so that the liquid paraffin continuously output by the paraffin melting tube can be temporarily stored in the temporary paraffin storage box when the paraffin dropping tube cavity stops discharging the paraffin. Furthermore, the paraffin discharging dropper can adjust the closing speed of the hinged bottom cover.

Description

technical field [0001] The invention relates to the technical field of wax block embedding machines, in particular to a method for releasing wax from a wax dropper of a tumor tissue automatic opening and closing type wax block embedding machine. Background technique [0002] For tumor patients, it is often necessary to conduct slice tests on suspected tumor tissues. Before slicing, the tissue needs to be embedded in drop wax to facilitate slicing. Paraffin embedding machine is a device for embedding human or animal or plant specimens in tissue wax blocks after dehydration and wax soaking for histological diagnosis or research after sectioning. It is suitable for medical colleges, hospital pathology departments, medical research units, It is used by animal and plant scientific research units and food testing departments. [0003] When the existing paraffin embedding machine performs embedding work again, the liquid wax drips on the workbench from the liquid wax outlet, part...

AI Technical Summary

Problems solved by technology

However, when the wax dripping in a certain embedding pool 9 ends and the next embedding pool 9 is moved to the lower part of the wax outlet 8 by moving the workbench 10, the wax outlet 8 will continue to drip wax on the moveable workbench 8 , causing unnecessary waste and pollution

Even if the wax outlet 8 is designed to be openable and coordinated with the movement of the mobile workbench 10 (the wax outlet 8 automatically closes the wax outlet when the mobile workbench 10 moves), it will require a higher cost, and due to the liquid wax It is not easy to realize its precise opening and closing due to its own weight
