Technical Field

[0001] The utility model relates to the technical field of sampling, in particular to a device for sampling sterile liquid in a non-clean area. Background Art

[0002] At present, the sampling of sterile liquids in non-clean areas is mainly carried out using sterile samplers, which can ensure that the sterile liquid is not exposed during the sampling process. However, each sampling requires the consumption of a disposable sterile sampling bag, and the sampling device must be installed in advance. The number of samplings is limited, and it will also cause cost consumption and environmental pollution. In addition, for some sampling non-sterile inspection items (such as physical and chemical index items), there is no sterility requirement for the sample itself, but it is necessary to ensure that the sterile liquid itself is not contaminated.

[0003] Based on this, a device for sampling sterile liquid in a non-clean area is proposed to facilitate the sampling of sterile liquid and avoid contamination of the sterile liquid. Utility Model Content

[0031] The liquid feed pipeline 2 is connected to the liquid feed tank 1. A tank bottom valve 3 is provided at the connection between the liquid feed pipeline 2 and the liquid feed tank 1 for releasing the sterile liquid in the liquid feed tank 1. A liquid feed valve 4 is also provided on the liquid feed pipeline 2 for controlling the filling of the sterile liquid.

[0032] The sampling pipeline 5 is connected to the feed liquid pipeline 2. A sampling isolation valve 6 is provided at the connection between the sampling pipeline 5 and the feed liquid pipeline 2 for isolating the feed liquid pipeline 2 and the sampling pipeline 5. A sampling valve 13 is provided on the sampling pipeline 5 for sampling. A temperature sensor 14 is also provided on the sampling pipeline 5 for detecting and recording the temperature in the sampling pipeline 5.

[0033] The cleaning pipeline includes a flushing water pipe 7 and a gas pipeline 9. The flushing water pipe 7 is connected to the sampling pipeline 5 and injection water is introduced into the sampling pipeline 5 to flush the pipeline. The flushing water pipe 7 is provided with an injection water valve 8 for controlling the injection water to flush the sampling pipeline 5. The gas pipeline 9 is connected to the sampling pipeline 5 and steam and compressed air are introduced into the sampling pipeline 5. The gas pipeline 9 is provided with a steam valve 10 for pressure-maintaining sterilization of the sampling pipeline. The inlet end of the gas pipeline 9 is connected to a steam pipeline 11 for introducing steam and an air pipeline 12 for introducing compressed air. The sampling pipeline is pressure-maintained and sterilized by introducing steam, which sterilizes the sampling pipeline 5. The sterilized sampling pipeline 5 is cooled and blown dry by introducing clean compressed air to complete the cleaning of the sampling pipeline 5.

[0034] Among them, the end of the sampling pipe 5 is connected to a condensate pipe 15, and the condensate pipe 15 is provided with a pre-drain valve 16 and a drain valve 17. The drain valve 17 is used to control the discharge of condensate during the pressure-maintaining sterilization process, and the drain valve 17 is used to discharge condensate.

[0035] The end of the sampling pipeline 5 is connected to a discharge pipe 18 , and a discharge valve 19 is provided on the discharge pipe 18 for discharging the liquid in the sampling pipeline.

[0036] The workflow of the utility model is:

[0037] When it is necessary to sample the liquid in the liquid tank 1, first open the tank bottom valve 3, then open the sampling isolation valve 6. At the same time, ensure that the sampling valve 13, the drain front valve 16 and the discharge valve 19 are in the closed state, and the sterile liquid enters the sampling pipeline 5 through the liquid pipeline 2. When enough liquid is stored in the sampling pipeline 5, close the tank bottom valve 3 and the sampling isolation valve 6, open the sampling valve 13 for sampling, and after the sampling is completed, close the sampling valve 13, open the discharge valve 19 to discharge the remaining liquid, and then open the water for injection valve 8 to pass the injection water to clean the sampling pipeline 5. After cleaning, close the water for injection valve 8 and the discharge valve 19, and then open the steam valve 10 and the drain front valve 16 to sterilize the sampling pipeline under pressure (the sterilization process selects 121°C, 12 minutes of over-killing method), and finally pass clean compressed air into the sampling pipeline for cooling and drying, and the sampling is completed.

[0038] Example 2

[0039] This embodiment further illustrates the technical solution of the utility model based on the embodiment 1.

[0040] The sampling pipeline 5 includes a stainless steel pipeline 501 and a plexiglass pipeline 502 which are interconnected. By setting a part of the sampling pipeline 5 as the plexiglass pipeline 502, after the sterile liquid enters the plexiglass pipeline 502 through the liquid pipeline 2, the inspector can close the tank bottom valve 3 and the sampling isolation valve 6 after observing that enough liquid is stored in the sampling pipeline 5, which makes it convenient for the inspector to clearly observe the liquid situation in the pipeline and facilitate the sampling operation.
