An in vitro drug sensitivity detection device for chemotherapy resistance of pancreatic cancer liver metastases

Abstract

The invention discloses an in vitro drug sensitivity detection device for pancreatic cancer liver metastases chemotherapy drug resistance, which belongs to the technical field of external drug sensitivity detection devices. Align the catheter assembly to the top of the petri dish, and then start the corresponding electric adjustment assembly to drive the T-shaped piston rod assembly to run. The liquid is first introduced into the piston cavity through the T-shaped piston rod assembly and the one-way valve assembly, and then passes through the T-shaped piston rod assembly. The type piston rod assembly cooperates with the catheter assembly to flow into the petri dish for quantitative and accurate addition of liquid, and at the same time, the timer is used for timing, and a reminder is given when the measurement time is reached.

Description

technical field [0001] The invention relates to an external drug sensitivity detection device, in particular to an external drug sensitivity detection device for pancreatic cancer liver metastases chemotherapy drug resistance, and belongs to the technical field of external drug sensitivity detection devices. Background technique [0002] Pancreatic cancer is a malignant tumor of the digestive tract. [0003] Among them, pancreatic cancer liver metastasis is the most common. Pancreatic cancer liver metastasis is an important manifestation of serious disease, and it is relatively difficult to treat. The most important thing at this time is that the patient should be mentally prepared. Active and effective treatment can improve to a certain extent. patient quality of life. [0004] Currently, gemcitabine is more commonly used for the treatment of pancreatic cancer liver metastases with chemoresistance; [0005] Gemcitabine is a new cytosine derivative, like cytarabine, which ...

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.
