Virus-collecting filter for medical aspirator system

A molded body filter that prevents passage of bacteria and viruses, the molded body filter being used for a medical aspirator system which includes

• a suction port to connect to a suction catheter to take in exhaled breath and secretions from a patient or a user,
• a rigid container main body and a lid portion thereof,
• a space which is provided in a void formed by the rigid container main body and the lid portion and retains only the secretions out of the exhaled breath and the secretions, and
• a discharge port provided to the rigid container main body to discharge an air and the exhaled breath other than the secretions retained in the space, the discharge being performed by an aspirator main body outside the rigid container main body,
• the molded body filter being configured so that the air and the exhaled breath other than the secretions always pass though the molded body filter before being sucked into the aspirator main body, and being placed in an airtight manner at a position downstream of a retention space for the secretions in a flow direction of the air and the exhaled breath, preventing passage of bacteria and viruses which may be contained in the exhaled breath and the secretions, wherein
• a base material of the molded body filter is formed of at least two materials which are a material including sodium carboxymethyl cellulose (CMC) in powder form and an electrically-charged nonwoven fabric, and
• the electrically-charged nonwoven fabric is placed downstream of the material including CMC in powder form in the flow direction.
