Description

Technical Field

[0001] The utility model relates to the technical field of pathological specimen preservation, in particular to a multi-chamber bag. Background Technique

[0002] In the fields of medical treatment and medical research, the preservation and processing of pathological specimens are key links to ensure the accuracy of diagnosis and the effectiveness of treatment plans. In clinical work, when performing pathological examinations on complex tissue specimens such as hollow organs, steps such as paraffin sectioning, immunohistochemistry, molecular pathology, and oncogene examination are usually required to clarify the diagnosis and formulate corresponding treatment plans. In this process, the fixation and preservation of specimens are particularly important.

[0003] However, there are obvious deficiencies in the commonly used methods for fixing and preserving hollow organ specimens in the current medical field. Traditionally, specimen bags or bottles are mostly used to directly contain specimens. This method has the following main problems:

[0004] 1. Inadequate contact between the specimen and the fixing fluid: Due to the buoyancy effect, the specimen may float in the fixing fluid, resulting in some parts of the specimen not being able to come into full contact with the fixing fluid, affecting the fixing effect.

[0005] 2. Specimen stacking: The direct containment method easily causes specimens to stack together, which not only increases the risk of cross-contamination between specimens but also may lead to uneven distribution of the fixing fluid, affecting the fixing effect.

[0006] 3. Inconvenient operation: Most of the existing specimen containers are simply designed and cannot provide enough operating space, making the process of fixing and preserving specimens complex and time-consuming.

[0007] 4. Poor sealing performance: Some containers have poor sealing performance, which is likely to cause the volatilization of the fixing fluid or the entry of external pollutants, affecting the quality of the specimens.

[0008] 5. Poor reusability: The materials of some containers are not suitable for repeated use, and they need to be replaced after each use, increasing the cost and being unfavorable to environmental protection.

[0009] In response to the above problems, existing technical solutions such as the hollow organ pathological specimen fixator with the patent application number CN2014204013190, the specimen bag with formalin solution with the patent application number CN2022204391536, and the pathological specimen bag with the patent application number CN2022200072531, although they have improved the fixing effect of specimens to a certain extent, they still have not completely solved the above problems, especially the problems of inadequate contact between the specimen and the fixing fluid, inconvenient operation, and poor sealing performance. Therefore, we provide a multi-chamber bag. Content of the Utility Model

[0010] To solve the above problems, the present utility model proposes a multi-chamber bag, which more precisely solves the problems raised in the above background art.

A limit insertion plate is fixedly connected to the lower surface of the lapping plate. A reset structure is connected between the strip-shaped groove and the sliding sleeve block. A top self-sealing component is installed at the upper end of the specimen chamber bag.

[0015] Further, the reset structure includes a vertical fixing rod fixedly connected between the two end walls of the strip-shaped groove. A spring is sleeved on the periphery of the vertical fixing rod. The sliding sleeve block is slidably sleeved on the periphery of the vertical fixing rod.

[0016] Further, the top self-sealing component includes a first bag mouth and a second bag mouth fixedly installed at the upper opening end of the specimen chamber bag. A sealing rubber strip is fixedly connected to the surface of the first bag mouth. A sealing groove is opened on the surface of the second bag mouth. The sealing rubber strip is in interference fit with the sealing groove.

[0017] Further, one end of the fixing liquid chamber bag is connected through with a liquid adding pipe. A piston sleeve is sleeved on the periphery of the end of the liquid adding pipe.

[0018] Further, one end of the docking block is inserted into the inner wall of the rectangular opening. The lower end of the limit insertion plate penetrates through the end wall of the rectangular through slot and is inserted into the inner wall of the limit slot.
