[0002] During the drug detection process, in order to reduce the detection cost, enterprises need to prepare their own working reference substances. Working reference substances are widely used in quality control laboratories, mainly for internal content determination, identification, inspection, etc. In order to ensure the stability of the working reference substances, after being dispensed into vials, the vials need to be filled with nitrogen. After filling with nitrogen, the rubber stoppers are covered and crimped, which is beneficial for long-term storage and use. In actual work, we first cover each reference substance bottle after dispensing with a rubber stopper. When filling with nitrogen, the rubber stopper needs to be removed, and then the nitrogen pipe is used to fill nitrogen into the bottle for a while, and finally crimped. Each reference substance bottle is operated repeatedly in this way, and the nitrogen filling situation in the bottle cannot be stably controlled, and the nitrogen filling efficiency of the working reference substances is relatively low.

DETAILED DESCRIPTION

[0016] The utility model is further described below in conjunction with the accompanying drawings in order to better understand the technical solution.

[0017] The utility model discloses a portable nitrogen filling device for working reference products, which is used to replace the existing nitrogen filling operation of working reference product subpackaging, improves work efficiency, and realizes the purpose of convenient nitrogen filling operation and more stable subpackaging working reference products.

[0018] Specific structure such as Figures 1 - 3As shown, the device includes a nitrogen-filled box 1 made of polytetrafluoroethylene and a rubber stopper installer 2. Inside the nitrogen-filled box 1, there is a placement tray 4 for placing vials 3. The front side of the nitrogen-filled box 1 is an open end for the installation of the placement tray 4. Specifically, on the inner walls of both sides of the box body of the nitrogen-filled box 1, there are corresponding card slots 8 for the two sides of the placement tray 4 to be inserted. The placement tray 4 is evenly provided with a plurality of vial placement grooves 9. The open end is provided with two transparent double doors 7, which facilitates observing the nitrogen filling situation of the working reference substance. On the nitrogen-filled box 1, there are also symmetrically arranged handles 11, and the handles 11 facilitate the transfer of the nitrogen-filled box 1. On one side wall of the nitrogen-filled box 1, there is also installed an inflation interface 6, and on the inflation interface 6, there is also a flow valve 12 for controlling the size of the nitrogen flow. The inflation interface 6 is connected to the nitrogen pipeline. On the outer wall of the nitrogen-filled box 1, there is a concentration display instrument 13 for detecting the nitrogen concentration inside the box body of the nitrogen-filled box 1, which facilitates the capping operation according to the displayed concentration value situation.

[0019] Continue to refer to Figures 1 - 3 , on the top of the nitrogen-filled box 1, there is a rubber stopper installation hole 5 that cooperates with the placement tray 4. The rubber stopper installation holes 5 are arranged in one-to-one correspondence with the vial placement grooves 9, and inside the rubber stopper installation holes 5, there are three fan-shaped silica gel sheets 10 for plugging the rubber stopper installation holes 5 to prevent a large amount of air from entering the box body and thus affecting the purity. The rubber stopper installer 2 includes a cylinder 201, a pressing rod 202 arranged inside the cylinder 201, a clip button 203 arranged at the top of the pressing rod 202 and extending out of the upper end of the cylinder 201, a baffle 204 fixedly arranged at the lower part of the pressing rod 202, and a connecting block 205 connected to the baffle 204. The pressing rod 202 and the baffle 204 are connected by an annular spring 208. Below the connecting block 205, there is a conical boss block 206 that can enter and exit the cylinder 201, and at the lower end of the cylinder 201, there are four clips 207.

[0020] When the utility model works, the vials 3 containing working reference substances are sequentially placed in the vial placement grooves 9, and then the placement tray 4 is pushed into the nitrogen filling box 1 through the card slots 8. The two double doors 7 are closed, and the inflation interface 6 is opened to fill nitrogen into the vials 3 located inside the box. The nitrogen concentration inside the box is observed through the concentration display instrument 13. After reaching the predetermined concentration, the inflation interface 6 is closed, and then capping is performed through the rubber stopper installer 2. The specific steps are as follows: press the clip button 203, the annular spring 208 is compressed, the pressing rod 202 moves downward as a whole, the conical boss block 206 is pushed out of the pressing rod 202, and then the clip 207 provided at the bottom of the pressing rod 202 is pushed open. The four clips 207 are opened, the vial rubber stopper is placed inside the four clips 207, the clip button 203 is released, the annular spring 208 resets, the conical boss block 206 moves upward, and the four clips 207 contract to clamp the vial rubber stopper. Then it enters the box body of the nitrogen filling box 1 through the rubber stopper installation hole 5 and corresponds to the vial mouth on the placement tray 4. Press the clip button 203 again and apply a downward force, so that while the clip 207 is opened, the vial stopper is stuck into the vial mouth to complete capping.
