Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a filtering and collecting device. Background Art

[0002] Disposable / disposable biopharmaceutical equipment and consumables have been irradiated and sterilized before delivery to customers and are always in a sealed state. Customers can use them directly after receiving them without the need for further irradiation and sterilization. During the process of cell culture or microbial reaction using disposable / disposable biopharmaceutical equipment and consumables, the target product will continue to accumulate in the reaction vessel. In order to continue production, a filter can be used to filter out the target product to reduce the concentration of the drug solution and achieve the purpose of continuous production.

[0003] Currently, filters are usually independent devices. When in use, they need to be connected to the reaction device, and then connected to the collection device through a pipeline. The drug solution is drawn from the reaction device into the filter, filtered by the filter, and then the target product is transported to the collection device.

[0004] However, the independently installed filter needs to be sterilized separately before being connected to the sterilized reaction device and collection device. The whole process is relatively cumbersome and loses the advantages of speed and efficiency of disposable / disposable biopharmaceutical equipment and consumables. Utility Model Content
