As shown in fig. 1, fig. 3 and fig. 4, a reagent kit for virus inspection according to an embodiment of the present invention is provided with an air bag 3 on a dropper 2 and a rubber valve 5 inside the dropper 2, so that when taking reagent in a reagent kit, the air bag 3 on the dropper 2 is repeatedly squeezed to reduce the possibility of reagent solution contamination, and the device does not need to repeatedly extend the dropper 2 into the reagent kit for operation, and specifically, the device provided herein comprises a seal head 1 screwed on an opening of the reagent kit, the seal head 1 is provided with a half-open internal threaded tube communicating with the solution inside the reagent kit, in order to ensure the normal supply of reagent solution, the dropper 2 is fixedly and communicatively provided at the bottom of the half-open part of the seal head 1, and when in use, the reagent kit is inverted and a drip nozzle of the dropper 2 extends into the target test tube, in order to ensure that the solution in the reagent kit can be extracted according to the actually required dosage, an action opening is arranged on the dropper 2, an air bag 3 is fixedly arranged at the position of the action opening, the air bag 3 has good tightness and is communicated with the inner space of the dropper 2, the pressure inside the dropper 2 is changed when the air bag 3 acts, and the reagent solution is taken and used through the change of the pressure, in order to realize the structure, fixing rings 4 are fixedly arranged on the inner wall of the dropper 2 and on two sides of the position of the air bag 3 (the mounting positions and the structures of the fixing rings 4 can be set as shown in figure 3, it should be noted that the fixing rings 4 are arranged in a circular ring plate structure, and rubber valves 5 are fixedly arranged on one surfaces of the two fixing rings 4 facing to the dripping opening of the dropper 2, the control of the liquid passage is realized through the action of the rubber valve 5, specifically, two rubber valves 5 are arranged to be in an inverted cone structure, the tips of the two rubber valves are directed to one side of a drip opening of the dropper 2, when the air bag 3 is pressurized, the upper rubber valve 5 can be closed by the compression of the air bag 3, the passage of the liquid can be opened by the overlarge pressure of the lower rubber valve 5, when the air bag 3 recovers the initial position under the self elastic action, the lower rubber valve 5 is closed, the upper rubber valve 5 is opened by negative pressure and the reagent solution is drained, the air bag 3 can effectively extract the solution reagent in the reagent box through the reciprocating work, and when the extracted amount is required to be controlled, the solution volume obtained by extruding the air bag 3 once is calculated and the corresponding times of extrusion are carried out.

As shown in fig. 3 and 4, since the rubber valve 5 needs to control the normal sealing function of the air bag 3 when not acting, the port of the rubber valve 5 is squeezed and blocked in the normal state, and it is considered that the air bag 3 generates a certain negative pressure inside the two rubber valves 5 when recovering, in order to prevent the negative pressure from being too large and balanced with the position of the air bag 3, and the air bag 3 cannot be recovered normally, a spring 6 for normally bouncing and returning the air bag 3 is arranged inside the air bag 3, and the attraction force of the negative pressure to the air bag 3 is overcome by the elastic force action of the spring 6.

As shown in fig. 3, in order to avoid reagent leakage caused by insufficient sealing performance when the reagent kit is inverted, a rubber gasket 7 (a hollow gasket is adopted as the structure of the rubber gasket 7 shown in fig. 3) for being tightly matched with the opening of the reagent kit is arranged on the inner wall of the seal head 1 and at the position of the half opening, when the seal head 1 is tightly screwed on the opening of the reagent kit, the opening of the reagent kit is tightly contacted with the rubber gasket 7, the elastic extrusion effect greatly reduces the gap of the equipment, and the good sealing performance of the reagent in the extraction process is effectively ensured.

As shown in fig. 1 and 3, in some slightly larger reagent kits, the reagent kit is inverted to be inconvenient for taking a reagent, at this time, in order to ensure that the reagent kit can be used for extracting a reagent solution in a normal placing state, a guide block 8 is in threaded connection with the inside of the end socket 1 (the structure and the installation position of the guide block 8 are shown in fig. 3), a communication port for communicating with the dropper 2 is formed in the middle of the guide block 8, a suction pipe 9 for inserting into the corresponding reagent kit is inserted into the communication port in a matching manner, and when negative pressure is generated inside the two rubber valves 5, the negative pressure is conducted to the inside of the suction pipe 9, and then the suction of the solution is started.

As shown in FIG. 1, in order to increase the effect of the rubber pad 7, the bottom of the guide block 8 needs to be arranged to be in close contact with the rubber pad 7, the whole of the guide block 8 is hollow cylindrical, and a plurality of anti-slip stripes parallel to the axis direction of the guide block 8 are arranged on the outer wall of the guide block 8, so that the screwing length of the guide block 8 which can be inserted deeply is increased by increasing the friction effect of the hand on the guide block 8, and the good sealing performance of the rubber pad 7 is ensured.

As shown in fig. 1, in order to facilitate adjustment during the suction operation, the suction tube 9 is a neutral hose, and to ensure that the suction tube 9 can be inserted well into the bottom of the reagent kit, the setting device further includes a sealing cover 10 connected to the opening of the reagent kit by a screw thread, a through hole is formed in the middle of the sealing cover 10, an annular rubber ring is padded on the through hole at the position, and the suction tube 9 is inserted into the annular rubber ring and inserted into the bottom of the reagent kit (note here that the sealing cover 10 should not completely seal the reagent kit, and the external gas needs to enter the reagent kit and ensure that a certain air pressure exists in the reagent kit to supply liquid to flow upwards).
