Wax outlet dropper of automatic opening and closing type wax block embedding machine for tumor tissue

Abstract

The invention relates to a wax outlet dropper of an automatic opening and closing type wax block embedding machine for tumor tissue. The wax outlet dropper is used for dropping molten liquid wax in awax melting box into a wax collecting box and comprises a wax dropping pipe cavity, a hinged bottom cover, a linkage pull rod, a temporary wax storage box and a high-pressure pressure spring. The waxoutlet dropper in the invention can automatically discharge wax and stop wax discharging, wax can be automatically discharged after the wax outlet dropper is inserted into the wax dropping pipe cavity, then the wax discharging can be automatically stopped after the wax dropping pipe cavity is pulled out, the continuous work of a wax melting pipe is not affected in a wax discharging stopping period, and liquid wax continuously output by the wax melting pipe can be temporarily stored in the temporary wax storage box under the condition that wax discharging of the wax dropping pipe cavity is stopped. Furthermore, the closing speed of the hinged bottom cover can be adjusted through the wax outlet dropper.

Description

technical field [0001] The invention relates to the technical field of wax block embedding machines, in particular to 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 of the liquid wax will enter th...

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
