Aspirator without partition wall for collection of bodily fluids including improved safety and efficiency elements

An aspirator for removing bodily fluid through human suction and subsequent collection of the removed bodily fluids, comprising:

• a. a container having a bottom wall and a side wall, defining an internal chamber;
• b. a top having a first aperture therein and a second aperture therein spaced apart from the first aperture;
• c. said first aperture opening into said internal chamber and said second aperture opening into said internal chamber;
• d. a first hollow tube having two ends, with the first end inserted through said first aperture such that said first hollow tube opens into said internal chamber and said second end extends for a distance beyond the top and further comprises at least one opening adjacent the tip of the second end;
• e. a flexible bellows member comprising an integrally formed flexible bellows and terminating in a sealed bottom at one end and affixed to a bellows cap at its other end;
• f. said bellows cap having an opening extending into the bellows and attached to the top of said container such that the opening in the bellows cap is aligned with said second aperture in the top of the container;
• g. the top of said container further comprising means for receiving a hollow tube in alignment with said second opening, the means comprising a central opening for fluid communication with the second aperture and bellows;
• h. a second hollow tube having two ends, with the first end attached to said means for receiving a hollow tube aligned with said second opening and the second end attached to a mouthpiece, to thereby provide a closed system permitting gaseous communication between the mouthpiece, the second hollow tube, the bellows cap and the bellows;
• and
• i. said flexible bellows extending into said internal chamber such that the flexible bellows is in its fully expanded position when in its equilibrium state, the flexible bellows providing a fluid barrier within the container between the first end of said first hollow tube and the first end of said second hollow tube;
• j. the portion of said first hollow tube within said chamber residing external to said bellows;
• n. whereby in use, the second end of said first hollow tube is inserted into the patient from which bodily fluid is to be removed and the mouthpiece of the second hollow tube is sucked on by the person treating the patient, and suction through the mouthpiece will cause said flexible bellows to contract to thereby create a vacuum in said internal chamber which through gaseous communication with first hollow tube causes air and bodily fluids from the patient to be sucked into and remain in the internal chamber while the airtight system from the mouthpiece through the flexible bellows prevents any direct communication of air or bodily fluids between the patient and the person treating the patient;
• k. the top of said container further comprises a joining member attached to the underside of said top and extending into the internal chamber, and further including a slot therein;
• l. the means for receiving a hollow tube is a nipple extending out of the upper surface of the top of the container;
• and
• m. the opening in said bellows cap is attached to the joining member at the location of the slot.
