Description

Technical Field

[0001] The utility model relates to the technical field of biopharmaceuticals, in particular to a sensor structure of a drug liquid pipeline. Background Art

[0002] During the production phase of biopharmaceutical companies, real-time monitoring of drug fluid data is usually achieved by attaching sensors to pipelines that carry the drug fluid.

[0003] After the drug liquid conduction is completed, the drug liquid conduction pipeline needs to be cleaned. The interior of the fixed sensor has a large dead volume, which is easy to produce residues, thus causing the drug liquid to be contaminated. Therefore, more and more customers in the biopharmaceutical industry are using disposable consumables. Disposable consumables are mainly sterilized by irradiation and do not need to be cleaned again after one-time use.

[0004] Existing fixed sensors cannot be integrated into disposable consumables, cannot be used in conjunction with each other, have a large dead volume inside, and are difficult to assemble. In addition, the styles of fixed sensors are all one connector adapted to one main body, and can only adapt to pipelines according to the pipe diameter. There are more than 10 types of connector specifications applicable to biopharmaceutical processes. Taking two-way connectors as an example, there may be dozens of specifications for both ends of the connector. Currently, common sensor manufacturers only manufacture the most common specifications for cost considerations. This requires biopharmaceutical users to sometimes use reducers to transfer to other specifications, which is cost-effective and may actually cause more dead volume or other types of operational inconveniences.
