Abstract
An aspirator for manually collecting liquid samples, particularly for medical purposes, comprising a handle connected to a vacuum source and having a sample collection vial fitting into a cavity in the handle with a finger control vent in the cavity and having a tubing to function as the probe for the sample to be collected, the tubing leading into the sample collection vial.
Claims7
An aspirator for manually collecting samples of fluids from remote human body cavities comprising an elongated axially extending handle having a top surface, a bottom surface, a forward end, a rearward end, a centrally located cavity opening through said bottom surface of said handle, said handle between said cavity and said rearward end providing means for manually gripping thereof, a rigid passageway extending through said handle communicating said cavity with said forward end and said rearward end, said handle having an aspiration control finger vent located directly above the cavity and communicating with said cavity and said passageway through said top surface;
- a removably attached specimen collecting vial having an open top in air-tight attachment to said cavity;
- a separate removable flexible tube means extending from within said cavity and vial through said passageway and outwardly beyond said forward end for a predetermined distance, said tube means including means for providing an air-tight seal with said passageway;
- a removable length of a metal hollow tube extending outwardly from said forward end and encircling said flexible tube in an air-tight manner;
- and said rearward end including means for connecting said passageway to a source of vacuum.
In a fluid aspirator-collector, the combination of an elongated barrel means forming a handle for gripping thereof and having a first end, a second end, a top surface, a bottom surface, a cavity opening outwardly through said bottom surface intermediate said ends, a longitudinal passageway extending from each of said ends and intersecting said cavity, and an aspiration control thumb vent from said top surface extending into said cavity;
- a removable metal hollow pipe extending from said first end and having its central passage in communication with said passageway and having a free end disposed outwardly beyond said first end and an opposite end located within said passageway;
- a specimen collection vial removably attached to said handle in air-tight communication with said cavity;
- and a flexible tube inserted through said central passage of said pipe and being air-tight with respect thereto, said tube extending from said cavity and vial to a free end a predetermined distance beyond said free end of said pipe said second end including means for connecting said passageway to a source of vacuum.
