Definitions
- a cervical canal specimen collector including a hollow tube having an upturned end.
- a piston near the outer upturned end of the tube is movable manually from a first position where it closes the end of the tube to provide for ease of insertion of the device, to a position drawn within the tube to draw fluids within the tube for subse quent microscopic inspection.
- a probe may be carried by the outer end of the piston, which probe may penetrate further into the organs involved and at the same time, when withdrawn, scrape cell-carrying fluids from adjacent tissue for subsequent examination.
- This invention relates to a specimen collector and more particularly to a specimen collector particularly adapted to withdraw fluids from the cervical canal.
- Another method for obtaining specimens of cervical fluid is to use a bulb attached to a tube, which is inserted into the cervical canal, and with suction draw fluid into the end of the tube.
- a bulb attached to a tube, which is inserted into the cervical canal, and with suction draw fluid into the end of the tube.
- a cervical canal specimen collector which can be safely and easily inserted into the cervical canal and moved the desired distance upwardly therein and when so positioned can positively effect a withdrawal of the fluid present in such upper regions. Furthermore, after the device has been withdrawn, the fluid collected therein can be positively discharged from the collector for subsequent examination.

- FIG. 10 is a vertical section taken along the line 10--10 of FIG. 6;
- FIG. 11 is a vertical section taken along the line 11-11 of FIG. 8.
- the specimen collector 10 comprises a tube 11, preferably made of plastic or the like and being straight throughout the greater portion of its length but having an upturned end at its outer extremity.
- the inner portion of the tube 11 is enlarged as at 13 forming therein a cylindrical chamber 14.
- integrally formed on the outer surface of the enlarged portion 13 are finger grips 15 to assist in the manipulation of the device.
- a plunger 16 Reciprocably mounted within the chamber 14 is a plunger 16 generally X-shaped in cross section as shown in FIG. 5.
- a piston 17 is positioned adjacent the outer end 12 of the rod with the piston being provided with a rounded outer portion 18 and with seals 19 sealingly engaging the inner surfaces of the tube portion 12.
- a piston rod 20 is secured at one end to the piston 17 and at its other end to the plunger 16.
- a manually engageable member 21 positioned exteriorly of the enlarged portion 13 is secured to the plunger 16 so that movement of the member 21 serves to move the plunger, the piston rod, and hence the piston.
- the device In use, the device is in the position shown in the drawings, i.e., with the piston 17 located at its outermost position so that its rounded end 18 protrudes or projects beyond the end of the curved portion of the tube.
- a closed-end blunt instrument easily insertable into the cervical canal without causing either injury or discomfort.
- the member 21 When so inserted, the member 21 is moved outwardly to draw the piston back into the tube and such movement, because of the seals 19, draws by suction cervical canal fluid into the thus open end of the tube.
- the depth of penetration of the end 12 into the cervical canal is limited by a disc 22 secured to the end 12 as shown.
- the fluids collected may be forcibly and positively ejected from the tube by moving the member 21 to its original position and moving the piston outwardly to the open end of the tube. It will be realized, of course, that all fluids are thus fully removed from the tube for further examination.
- the specimen collector comprises a cylindrical outer tube provided with alternately spaced openings 31 on opposite sides thereof.
- the openings are provided merely to adapt the outer tube to a configuration which is easily molded by injection molding techniques as presently known.
- the outer tube 30 is provided with an upturned end portion 32 integrally connected to a straight portion 33. Secured within the upturned portion 32 of the outer tube 30 is a hollow inner tube 34. At the opposite end of the outer tube 30 is a pair of finger grips 35 to facilitate handling of the device.
- a piston 36 Located within the hollow tube 34 is a piston 36 provided with a plurality of rings 37 providing a close fit with the interior surface of the tube 34.
- the piston 36 terminates in a rounded end portion 38 from which extends an axial probe 39 terminating in a rounded end 40 but formed, as shown in the drawings, in a general umbrella shape so as to provide the annular shoulder 41 for the purposes hereinafter described.
- the piston 36 is secured to a piston rod 42 which extends through the outer tube 30 and outwardly therefrom, and a finger ring 43 is secured to the outer end thereof as shown for the purpose of moving the piston rod and hence the piston within the tubes.
- a disc of clear plastic 44 is secured to the hollow tube as is a generally wedge-shaped stop or catch member 45.
- the hollow tube 34 is inserted within the upturned end of the outer tube 30 until the disc 44 is seated against the end of said outer tube, at which time the wedge-shaped lock or catch 45 will have passed just into an opeing 31a in the outer tube, thus locking the hollow tube securely in position within the outer tube.
- the piston rod 42, piston 36, and probe 39 are integrally formed of a single piece of flexible plas tic which then may be inserted through the straight end of the outer tube to complete the assembly.
- the deviec shown in FIGS. 6-11 is used generally similarly to the specimen collector previously described.
- the piston rod is withdrawn to position the parts in the manner shown in FIG. 8 thereby providing a rounded end for insertion into the cervical canal.
- the clear disc serves to determine the amount of penetration and yet permits the physician to observe the insertion as it is taking place.
- the finger portion 43 is moved toward the outer tube to cause the piston and probe to move to the position shown in FIG. 9.
- the probe at this time will have penetrated substantially through the cervical canal and into the uterus and when withdrawn (by outward movement of the finger portion 43) the probe 39 will not only collect additional fluids, the edge portions 41 serve to scrape fluids from the surrounding tissue thus increasing the volume of the specimen obtained as well as securing fluid from the uterine area. Withdrawal of the piston rod also withdraws the piston and the suction thereby created pulls in additional fluid from the surrounding area.
- the outer end of the probe serves something as a shield to prevent loss of fluid withdrawn into the inner hollow tube and then the specimen collector may be withdrawn from the vagina and the specimen obtained submitted for examination.
