Abstract
Description
Technical Field
[0001] The utility model mainly relates to the technical field of pathological specimens, in particular to a specimen quantitative liquid adder. Background Art
[0002] Surgical pathology specimens are the standard for surgeons to diagnose diseases. To improve the accuracy of surgical pathology testing, surgically removed specimens must be quickly immersed in a 10% formalin fixative to prevent cellular hydrolysis, decay, and necrosis. However, formalin is toxic and volatile, and can easily irritate the conjunctiva and respiratory organs. Therefore, formalin must be stored in a sealed container to minimize leakage and evaporation.
[0003] At the same time, when fixing specimens, surgical staff need to manually press the formalin from the container or pour it into a conventional plastic specimen bag by opening the bottle cap. During this process, liquid can easily splash out, polluting the environment or damaging the eyes, and it can also easily lead to waste. In addition, different pathological specimens require different amounts of specimen fixative. Traditional clinical practice relies on medical staff to add the fixative by visual inspection, often resulting in excessive or insufficient addition of fixative, failing to meet the national standard requirement of 3-5 times the specimen volume. Furthermore, when medical staff add formalin to the specimen bag by hand, not only is it easy to spill the liquid, but close contact with formalin also poses certain risks.
[0004] Therefore, there is an urgent need for a specimen quantitative liquid adder that does not require medical staff to hold the specimen bag and can quantitatively add specimen fixative. Utility Model Content
