Tumor cell preparation device for constructing human pancreatic cancer rabbit pancreatic head xenograft tumor model

Abstract

The invention provides a tumor cell production device for human pancreatic carcinoma white rabbit pancreatic head transplantation tumor model construction and belongs to the technical field of medical imaging. The device comprises a port (1), an inclined nozzle (2), a neck (3), a device body (4), a stirring sucking device (5), a liquid control valve (6), a cavity (7), a culture plate (8) and a steam generator (21). The device is characterized in that the length of the culture plate (8) ranges from 6 to 18cm, the width ranges from 6 to 18cm, and the height ranges from 0.5 to 2cm; a Petri dish (10) is made of glass, the upper portion of the Petri dish is cylindrical, the lower portion is provided with a Petri dish bottom (33) with the surface in a dish shape, and the center of the bottom is provided with a dish bottom hole (15); the upper portion of the culture plate (8) is provided with a culture plate cavity (31) formed through a culture plate wall (32) in a surrounded manner, and the culture plate cavity (31) is provided with water inside; the lower portion of the culture plate (8) is provided with a dish bottom steam heating layer (12). The device is simple to manufacture, high in maneuverability, low in cost and has significant effect.

Description

Technical field [0001] The invention relates to a tumor cell preparation device for constructing a pancreatic head transplanted tumor model of human pancreatic cancer in a white rabbit, and belongs to the technical field of medical imaging. Background technique [0002] Pancreatic cancer is an extremely dangerous and highly malignant tumor of the digestive tract. In recent years, its age of onset has shown a significant younger trend. According to the National Institutes of Health, the morbidity and mortality rates are close to 1:1. Affected by factors such as the anatomy and biological characteristics of the pancreas, most of the patients are already at an advanced stage at the time of diagnosis, and the chance of surgical resection is only 15%-20% or even lower, and they are prone to recurrence and metastasis after surgery. Early diagnosis is a key factor in improving the prognosis of pancreatic cancer. At present, there is still a lack of an effective method for non-invasive ...
