Description

Technical Field

[0001] The utility model relates to the technical field of medicine, in particular to an automatic decalcification device for pathological bone specimens. Background Art

[0002] When making slices in pathological experiments, we often encounter some calcium-containing tissues, and calcium is very hard. Due to the difference in density between calcium and paraffin in the tissue, calcium-containing tissues generally cannot be directly sliced, but need to be decalcified:

[0003] Existing decalcification methods often use tissue decalcification fluid, which often uses some strong organic acids, or inorganic acids such as hydrochloric acid and nitric acid, and then manually prepares the solution in real time. Based on the technician's experience, a pin is used to puncture the bone specimen to test its hardness to determine whether decalcification is complete.

[0004] There are some problems with this decalcification method of manually preparing solutions and judging by personnel in real time. For example, it is highly dependent on manual labor and requires staff to detect bone specimens in real time. For this reason, we propose an automatic decalcification device for pathological bone specimens. Utility Model Content
