Description

Device for storing renal biopsy specimens

Technical Field

The utility model relates to a device for storing a renal biopsy specimen, and belongs to the technical field of medical equipment.

Background

The histopathological examination of renal biopsy is the gold standard for diagnosing renal diseases, and has great significance for clinical treatment and prognosis judgment of various types and stages of renal diseases for clinicians. Renal biopsy generally requires three examinations, namely, optical microscopy, immunopathology and electron microscopy, to make the final pathological diagnosis. In order to improve the accuracy of pathological diagnosis of renal biopsy, correct treatment of biopsy specimens is important in addition to smooth renal puncture operation. Successful pathology requires that the specimen not be autolyzed and destroyed by tissue and cells, and that the specimen must be rapidly cryopreserved and fixed. However, most of the renal puncture specimens in hospitals need to be sent to the nephrology department of the superior hospital for pathological examination, and the storage tube for holding the specimens is easy to be damaged, disordered, collided, leaked, polluted and other adverse conditions in the process of multiple transportation, so that the specimens lose stability. Therefore, a transport container is needed, which can not only effectively preserve the kidney biopsy specimen, but also ensure that the kidney tissue specimen is in a low temperature state of about 4 ℃.
