Embodiment 1

[0031] Embodiment 1: The jacking device includes a lever 15 arranged in the casing 1, one end of the lever 15 corresponds to the lower end of the jacking rod 3, and the other end of the lever 15 protrudes outside the casing 1, and the top of the casing 1 A limit card 16 is arranged corresponding to the lever 15 .

Embodiment 2

[0032] Embodiment 2: The jacking device includes an electric push rod 17 arranged in the housing 1 , and the electric push rod 17 corresponds to the lower end of the jacking rod 3 .

[0033] Further, the electric push rod 17 is provided with a timing device. After the set irradiation time is completed, the irradiation to the cells is automatically cut off, which has the characteristics of automation and does not require special personnel to take care of it.

[0034] The housing 1 is provided with an operation panel 12 of an electric push rod 17 .

[0035] The present invention can adopt small-sized electric push rod 17, and it has the advantage of low energy consumption, only needs to charge lithium battery and can finish driving.

[0036] Both the tray 5 and the upper cover 7 are made of lead glass material, which can completely shield the radioactive particles 9 from damage to the experimenter, and is also convenient for the operator to observe.

[0037] In addition, the p...

Abstract

The invention relates to a close range radioactive ray-induced cancer cell apoptosis model device and belongs to the technical field of biomedical experiment devices. The close range radioactive ray-induced cancer cell apoptosis model device has the advantages of simple structure, stability, reliability, good repeatability, use convenience and low cost. The device comprises a housing and a tray is arranged above the housing. The device is characterized in that particle clamps are radially arranged above the tray from the center to the periphery, a sleeve is arranged in the center in the housing corresponding to the lower part of the tray, an ejector rod is arranged in the sleeve, the upper end of the ejector rod corresponding to particles is radially provided with shield plates and an ejector rotation device is arranged at the lower end in the housing corresponding to the ejector rod.

Description

technical field [0001] The invention belongs to the technical field of biomedical experiment devices, and in particular relates to a close-range radiation-induced apoptosis model device of cancer cells. Background technique [0002] Primary liver cancer (hepatocellular carcinoma, HCC) (hereinafter referred to as liver cancer) is the third most common cancer worldwide. my country is an area with a high incidence of liver cancer, accounting for about 45% of global liver cancer cases. About 110,000 people die from liver cancer every year, and its mortality rate ranks second in China (26.26 / 100,000), which seriously threatens the health of the people. At present, early surgical resection is still the main method for the treatment of liver cancer. However, most patients are already in the advanced stage of liver cancer when they are clearly diagnosed, and only about 10-20% of them have the chance of surgery. The curative effect is not good due to the sensitivity of the drug, and...
