Collection and filtration via suction of biological material during surgical procedure

An apparatus for filtering bone from blood, comprising:

• (a) a liquid container having a single, open end comprising a mouth of the container;
• and
• (b) a cover removably attached to the container in sealing engagement with the mouth of the container;
• (c) wherein the cover comprises,
• (i) a suction port,
• (ii) a plunger including a press head, and
• (iii) a vent configured to permit air to enter through the cover into the container as a result of the application of suction via the suction port of the cover, the air entering into the container through an opening in the cover located proximate the mouth of the container and in spaced relation to the press head.

An apparatus for filtering bone from blood, comprising:

• (a) a liquid container having a single, open end comprising a mouth of the container;
• and
• (b) a screw-on lid removably attached to the container in sealing engagement with the mouth of the container;
• (c) wherein the lid comprises,
• (i) a suction port,
• (ii) a plunger including a press head, and
• (iii) a vent configured to permit air to enter through the lid into the container as a result of the application of suction via the suction port of the lid, the air entering into the container through an opening in the lid located proximate the mouth of the container and in spaced relation to the press head.

An apparatus for filtering bone from blood, comprising:

• (a) a liquid container having a single, open end comprising a mouth of the container that opens into a containment area of the container;
• and
• (b) a cover removably attached to the container in sealing engagement with the mouth of the container;
• (c) wherein the cover comprises,
• (i) a suction port,
• (ii) a plunger including a press head dividing the containment area of the container into a bottom area of the container and a top area of the container relative to the press head, the press head including a screen by which blood is permitted to pass between the bottom and top containment areas when the press head moves through the containment area, but by which bone is blocked from passing between the bottom and top containment areas when the press head moves through the containment area,
• (iii) a spring that biases the plunger into a position in which the press head of the plunger is located proximate the mouth of the container;
• and
• (iv) a vent configured to permit air to enter through the cover into the containment area as a result of the application of suction via the suction port of the cover, the air entering into the container through an opening in the cover located proximate the mouth of the container and in spaced relation to the press head.
