Problems solved by technology

Wax sealing can not only avoid wax block insects, but also reduce oxidation and slow down the loss of DNA and antigens; but at the same time, it takes a lot of time to seal wax, which increases a lot of workload. This problem has been plagued by many pathology departments. In the past few years, some pathology departments have no choice but to adopt the practice of not sealing wax under the background of increasing specimen volume.
Because the temperature is not easy to control in the hot coating method, the wax block is deformed. After the paraffin around the tissue melts at the same time, the tissue protrudes from the surface of the wax block, resulting in dry tissue and possible mildew. Moreover, the tissue is easily burned if the temperature is too high. Flattening, affecting the appearance of the archive
Tweezers scalding and simple smearing due to the temperature difference between the wax block and the sealed melted wax, the wax film is not firmly bonded to the tissue and is easy to peel off

Embodiment 1

[0029] A method for tissue wax block preservation, characterized in that the preservation steps are as follows:

[0030] Step 1. Start the equipment, check whether each function key 1 is in good condition, and check whether each display device is working normally;

[0031] Step 2. Perform temperature calibration on the device;

[0032] Step 3. Set the working temperature after the temperature calibration in step 2 is completed;

[0033] Step 4. After the temperature setting in step 3 is completed, add an appropriate amount of melted tissue section paraffin on the heating plate 12, and stop adding wax when the wax liquid absorbed by the collodion at the bottom of the tank reaches saturation;

[0034] Step 5. After slicing the wax block, hold the wax block in your left hand, with the cut side facing down, and place it in the wax tank. From left to right, quickly contact the collodion to complete the wax sealing by friction; remember not to press the collodion too hard, which ma...

Abstract

The invention belongs to the technical field of medical pathology, and relates to preservation of tissue wax blocks, in particular to a method for preserving tissue wax blocks. The method comprises the following steps: 1, starting equipment, checking whether each function key is intact or not, and checking whether each display device works normally or not; 2, carrying out temperature calibration on the equipment; 3, setting the working temperature after the temperature calibration in the step 2 is finished; 4, after the temperature is set in the step 3, adding a proper amount of molten tissue section paraffin to the heating plate, and stopping adding the paraffin when the paraffin liquid absorbed by the collodion cotton at the bottom of the tank is saturated; 5, after slicing of the wax block is finished, holding the wax block with the left hand with the section facing downwards, placing the wax block in a wax groove, and rapidly contacting and rubbing the wax block with collodion from left to right to finish wax sealing; 6, after slicing is completely completed, adding a proper amount of wax liquid into an instrument, and preparing for the next wax sealing work; 7, powering off the instrument and cleaning off wax stains around the instrument.

Description

technical field [0001] The invention belongs to the technical field of medical pathology and relates to the preservation of tissue wax blocks, in particular to a method and device for tissue wax block preservation. Background technique [0002] Tissue wax blocks are valuable medical information and an important part of pathological files. They play an important role in the continued diagnosis and treatment of patients, as well as in pathological teaching and scientific research. They are also physical evidence with important legal significance. Article 18 of the "Guidelines for the Construction and Management of Pathology Departments (Trial)" clearly states that the storage period of tissue wax blocks is 15 years or even longer. During this period, if the tissue wax block is not preserved properly and cannot be used, it will cause severe consequences. Therefore, how to preserve tissue wax blocks effectively for a long time is an important task for pathologists, especially p...
