Medical suction devices and uses thereof

A medical suction device, comprising:

• a compressible object;
• and
• a tubular member located inside the compressible object and comprising a first end, a middle section and a second end,
• wherein the first end comprises a first hole located at the opening and the second end comprises a second hole,
• wherein the compressible object comprises:
• (i) a surface;
• (ii) an opening in the surface;
• (iii) an internal lumen completely defined by the surface and the opening;
• (iv) a reservoir comprising a first space;
• and
• (v) a non-reservoir space located between a part of the compressible object opposite the opening and a plane containing the second hole and oriented perpendicular to the tubular member,
• wherein an interior surface of the middle section adjacent to the second hole comprises:
• (i) one or more ribs dimensioned to receive and hold a ribbed tip of a catheter, or (ii) threading dimensioned to receive and hold a threaded tip of a catheter,
• wherein the first space is located between the surface of the compressible object and the middle section,
• wherein the first space is located between the surface of the compressible object and the plane containing the second hole and oriented perpendicular to the tubular member,
• wherein the first space is located between the middle section and the plane containing the second hole and oriented perpendicular to the tubular member,
• wherein the lumen of the compressible object is in fluid communication with a second space outside the compressible object through the tubular member, and
• wherein the opening is a blind hole.
