Vial device for storing and smearing exfoliative cells

A device for storing and smearing exfoliative cells, comprising:

• a filter configured to receive a dispensed part the exfoliative cells and a liquid medium to determine the state of the exfoliative cells;
• a container member having a vial body and an entrance on the upper end of the vial body for containing the exfoliative cells and liquid medium inside thereof;
• a permeable membrane member (120) disposed inside and corresponding to the entrance of the container member, wherein the permeable membrane member blocks the exfoliative cells and liquid medium housed in the container member from being discharged down when the container member is disposed upside down with an application of external force and the entrance to the container member is positioned at the bottom, and wherein the permeable membrane member permits a part of the liquid medium and the exfoliative cells housed in the container member be discharged down when the container member moves downward until the permeable membrane member contacts the filter upon activation of an external force to smear the discharged exfoliative cells on the filter, wherein the external force on the filter causes the permeable membrane to be pushed upward, which compresses the space inside the vial body and increases the internal pressure therein which causes the exfoliative cells and liquid to penetrate the permeable membrane member and onto the filter;
• a membrane fixing member (130) mounted on the edge of the entrance of the container member and integrally fastened along the rim of the permeable membrane member;
• an elastic inner bridge connected to the inner wall along the rim of the inner wall of the membrane fixing member and is elastically connected from the body of the membrane fixing member, wherein the elastic force of the inner bridge reduces the magnitude of the external force which is applied to the connection portion between the membrane fixing member and the permeable membrane member when the container member is disposed in upside-down position with specimen being contained inside and the permeable membrane member is applied on an external force from the bottom;
• and
• an opening cap (140) configured to be detachably fastened with the membrane fixing member to block the permeable membrane member from moving through the membrane fixing member.
