In-vitro drug sensitivity detection device for drug resistance of pancreatic cancer hepatic metastasis chemotherapy

Abstract

The invention discloses an in-vitro drug sensitivity detection device for drug resistance of the pancreatic cancer hepatic metastasis chemotherapy, and belongs to the technical field of in-vitro drug sensitivity detection devices. A culture dish is kept at the same and appropriate temperature through a constant-temperature assembly, a positioning lifting frame assembly is started, and a liquid guide pipe assembly is accurately aligned to the upper portion of the culture dish; then a corresponding electric adjusting assembly is started to drive a T-shaped piston rod assembly to operate, the T-shaped piston rod assembly is matched with a one-way valve assembly to guide liquid into a piston cavity firstly, then the T-shaped piston rod assembly is matched with a liquid guide pipe assembly to enable the liquid to flow into the culture dish for quantitative and accurate liquid adding, and meanwhile timing is conducted through a timer; and reminding is carried out when the measurement time is up.

Description

Technical field [0001] The present invention relates to a foreign drug sensitive detecting device, and more particularly to a drug-sensitive detection device for phenoprota-free liver transfer chemotherapeutic resistance, belonging to the technical field of external drug sensitivity detection devices. Background technique [0002] Pancreatic cancer is a malignant tumor of a digestive tract, the condition is developing rapidly, the degree of deterioration is very high, and the late stage is extremely easy to move. [0003] Among them, there is a common manner that pancreatic cancer is most common. Pancreatic cancer is an important manifestation of serious condition. It is relatively difficult to treat. At this time, the patient is ready to be prepared in mind, and can improve to a certain extent by active effective treatment. Patient life quality. [0004] It is also a more common in the treatment of pnery-free blood transfer chemotherapy resistance to the treatment of pancreatic ...

AI Technical Summary

Problems solved by technology

[0009] In the prior art, there is no sensitive detection device for each group of cells exposed to different concentrations of gemcitabine. First, simultaneous measurement cannot be performed. Second, gemcitabine cannot be packaged uniformly during the addition process. Secondly, for temperature and humidity The maintenance of the drug is also relatively difficult, and the process of adding gemcitabine is also prone to the problem of dripping. Therefore, an in vitro drug sensitivity detection device for pancreatic cancer liver metastases chemotherapy resistance is designed to optimize the above problems.
