[0002] In the surgical operation process, the standard fixation of the resected specimen is a key link before pathological diagnosis. The current commonly used specimen fixation method in clinic mainly relies on the traditional specimen bag. However, the existing technology has exposed significant defects in actual application: when the medical staff pours the fixing liquid into the specimen bag through the open port, the volatile and irritating fixing liquid such as formaldehyde is prone to overflow, not only causing the pollution of the environment around the operating table, but also the harmful gas directly stimulates the respiratory mucosa of the medical staff, and long-term contact may cause occupational health risks. Related medical research shows that the exposure of fixing liquid in the operating room has become one of the potential causes of chronic respiratory diseases of medical staff.

[0003] At the same time, the existing specimen bag lacks airtight perfusion mechanism in the structural design, and the volatilization process of the fixing liquid exposed in the air is difficult to control, which not only leads to the loss of effective components of the fixing liquid and affects the specimen fixation quality, but also increases the concentration of harmful gas in the operating room. According to statistics, about 30% of the fixing liquid will overflow or volatilize due to operation negligence or extrusion in the traditional specimen fixation operation.
