5. The detection method of a tumor chemotherapy drug sensitivity detection kit according to any one of claims 1 to 4, characterized in that, The detection method includes the following steps: Step 1: Open the box cover (2). The two equal-volume drug delivery mechanisms (6) are filled with chemotherapy drugs and lysis buffer respectively. Twist the protective cap (501) to separate it from the test tube (5). Put the tumor cells to be tested into the six test tubes (5) in equal amounts. Twist the protective cap (501) to seal the test tubes (5). Then insert the six test tubes (5) into the well plate (101). The six test tubes (5) containing the test samples are arranged in a ring array below the equal-volume drug delivery mechanism (6) containing chemotherapy drugs. The six test tubes (5) correspond one-to-one with the six sets of sample injectors (4) at the bottom of the equal-volume drug delivery mechanism (6). Step 2: Cover the box (2), hold the extended end of the active bevel gear (3034) and turn it to make the active bevel gear (3034) rotate and drive the meshing gear transmission assembly (305) to rotate. The rotating gear transmission assembly (305) drives the rack lifting frame (304) to move down. The moving rack lifting frame (304) drives the storage tank (601) to move down through the lifting base frame (3033), so that the spline transmission assembly (306) extends downward under the influence of gravity. The downward-moving storage tank (601) causes the six sets of samplers (4) in the bottom annular array to move down through the rubber cap (502) and extend into the test tube (5). At this time, the samplers (4) expand the rubber cap (502) and the spring clamp (503). After the spline transmission assembly (306) extends to the set length, it reaches the spline engagement position to realize the transmission of rotational force. The rotational force is transmitted to the meshing bevel gear linkage assembly through the spline transmission assembly (306). The bevel gear linkage assembly drives the pressure dosing assembly and the power transmission mechanism (7) to work together. The running power transmission mechanism (7) opens the injection channels of the six sets of injectors (4). At the same time, the running pressure dosing assembly delivers the chemotherapy drugs inside the storage tank (601) to the test tube (5) through the injector (4). Step 3: After completing the delivery of equal amounts of chemotherapy drugs, the active bevel gear (3034) is rotated in the opposite direction. The reverse-rotating active bevel gear (3034) drives the meshing gear transmission assembly (305) to rotate in the opposite direction. The reverse-rotating gear transmission assembly (305) drives the meshing rack lifting frame (304) to move upward and drives the meshing spline transmission assembly (306) to rotate in the opposite direction. The reverse-rotating spline transmission assembly (306) drives the transmission bevel gear disk (604) to rotate in the opposite direction through the meshing transmission bevel gear set (603). The reverse-rotating transmission bevel gear disk (604) drives the threaded sleeve (606) to move upward through the lead screw (605). The upward-moving threaded sleeve (606) draws the liquid in the injection channel inside the flexible orifice seat (402). At the same time, the reverse-rotating lead screw (605) drives the linkage bevel gear disk (701) to rotate in the opposite direction, driving the liquid-stopping telescopic assembly (702) to extend and squeeze and deform the flexible orifice seat (402) to close the injection channel. At the same time, the upward-moving rack lifting frame (304) drives the lifting base frame (3033) to move upward, and the upward-moving lifting base frame (3033) drives the spline transmission assembly (306) to retract, unlocking the spline engagement, releasing the rotational force transmission, so that the flexible hole seat (402) remains in a closed state; The upward-moving lifting base (3033) drives the six sets of samplers (4) in the bottom ring array to move upward away from the rubber cap (502). The spring clamp (503) resets the contraction force to shrink and close the channel of the rubber cap (502), so that the test tube (5) forms a sealed detector dish. Step 4: After the chemotherapy drugs have fully reacted with the tumor cells, open the box lid (2) and move the six test tubes (5) after the reaction to the bottom of another set of equal volume dosing mechanism (6). The storage tank (601) in the equal volume dosing mechanism (6) contains lysis solution. Repeat steps 2 and 3 to deliver the lysis solution inside the storage tank (601) to the corresponding six test tubes (5) in equal volume. The cell membrane of the lysis solution is lysed, releasing intracellular ATP. Step 5: Open the box (2) and take out six test tubes (5). Mix the lysed cells in the six test tubes (5) with the luciferase-luciferin mixture. Under the catalysis of luciferase, ATP reacts with luciferin to generate a light signal. Use an enzyme-linked immunosorbent assay (ELISA) reader to detect the light intensity. Convert the RLU value into ATP content through a standard curve. Calculate the number of live cells or drug sensitivity based on the ATP content to evaluate the effect of chemotherapy drugs.
