MOLDED-BODY FILTER USING PTFE FILM, AND DISPOSABLE BAG OR CONTAINER FOR MEDICAL ASPIRATOR USING SAID MOLDED-BODY FILTER

摘要

Provided is a molded-body filter having an air permeability that is at least equivalent to that of PE sintered compact-CMC filters, short-term and long-term waterproofness, and improved bacteria barrier properties. Further provided is a disposable bag or container including the molded-body filter. A porous polytetrafluoroethylene (PTFE) film having a designated structure and pore diameter is used as the filter base material. The filter base material is thermally fused or adhered, via an adhesive, to a three-dimensional component that is internally hollow and has a support part for fixing the film-like filter base material, said support part being provided with a mesh-like rib preventing swelling toward the inner side of the filter base material, such that a molded-body filter is constituted by bonding to the support part so as to preserve the airtightness of the three-dimensional component. The molded-body filter is attached to the discharge port of a disposable bag or container such that internal exhalation and air inside the disposable bag or container definitely passes through when being discharged outside the disposable bag or container.
