9 Claims, 3 Drawing Figures 1 SPECIMEN-TAKING DEVICE BACKGROUND OF INVENTION This invention relates to specimen gathering devices for obtaining samples from inaccessible parts of body cavities.

It is the usual practice to employ trained medical personnel to obtain specimens and cultures for analysis from body cavities, such as the vagina, rectum, nose, ears, mouth or throat. The care that must be taken to obtain a specimen from the desired area of interest, precluding of contamination of the specimen taken, and minimizing of the chance of injury to delicate cavity areas, has required the use of trained personnel.

Consequently, it has been necessary for individuals to make appointments and to appear at doctors offices or hospitals to have tests made. This requirement entailed loss of time and considerable expense to the individual, contributing toward a negligent and procrastinating attitude regarding many tests that should be taken at regular time intervals.

The present invention seeks to correct this situation while making it possible for the individual to conveniently, safely, and correctly obtain their own specimen or culture which can then be forwarded directly to the laboratory for analysis.

SUMMARY OF INVENTION Accordingly, this invention contemplates providing a specimen gathering device which can be safely usedby untrained individuals to obtain their own specimens which can then be sealed and forwarded to a laboratory for testing and evaluation.

The specimen taking device is designed so that it is self-contained, and can be self-administered. The samples are sealed automatically to prevent contamination, and the device inserted within a container having identification data thereon. The entire assembly can then be mailed to the laboratory.

The specimen taking device permits an individual to safely obtain specimens from remote internal areas of DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of the two main parts of the invention.

FIG. 2 is a sectional view of the assembled unit.

FIG. 3 is a partial section of the insertion tube with the probe in extended specimen gathering position.

DESCRIPTION OF THE INVENTION FIGS. 1 through 3 show the preferred embodiment of the instant invention. FIG. 1 shows the specimen-taking device generally indicated 10, in perspective, with the tubular container or cover 12 removed. The container 12 has an identification label 14, which provides space for the name and the date to be placed thereon, as well as an identification or serial number. It is possible that such a label could be used to provide complete data, including the return address of the individual submitting the specimen. This would permit the laboratory to remove the label after the tests were completed and to affix it to a return envelope in which the results of the tests on the specimens by the laboratory were to be mailed back to the individual submitting the specimen.

The container 12 is of hollow construction and has an enclosed end 16 and an open end 18 which fitsover and around the cylindrical insertion tube assembly 20.

FIG. 2 which is a sectional view of the assembled specimen-taking device shows in more detail the structural configurations of the device. The cylindrical in-, v

sertion tube 20 has a rounded annular scraping edge 22, and an annular sealing surface 24 on the interior of the insertion tube 20 immediately adjacent to the annular scraping edge 22.- The other end of the cylindrical insertion tube 20 has a flanged annular seal construction 26 having an annular negative sloped sealing lip 28.

FIG. 2 shows the assembled specimen-taking device as it would be sold and as it would be shipped after use to the laborabory for testing. The specimen gathering piece generally indicated at 30 isshown in FIG. 2 in the retracted sealed position. It has an outer hemispherical probe section 32 and on the inner probe section is a reduced and tapered sample gathering section containing longitudinally extending ferrules 34'which contact and gather specimens. The smooth inwardly tapering section 36 of the insertion tube immediately behind the annular seal surface 24 is integral with a continuous tapered and conical shaped elastic diaphragm 38 which cooperates to form one of the walls of the annular chamber 40 between them and the ferrule section 34 of the specimen gathering member 30.

j The narrow neck section 42 of the specimen gathering member 30 connects the ferrule section 34 of the probe to the central portion of the generally conically shaped diaphragm 38. The intermediate section 46 is an integral part of the central and outer side of the flex-' ible diaphragm 38, as well as constituting the inner end of the operating stem 48 which has a knurled surface 50 to give good gripping action and prevent slipping when the user forces the stem 48 either inwardly or outwardly during the course of obtaining specimen material. 1

FIG. 3 shows the specimen gathering member in an, extended position, with the ferrules-34 exposed for obtaining sample material. It will be noted that the stem 48 has been pressed into the insertion tube 20 so that the forward end section 46 presses against the flexible plastic diaphragm 38 inverting it and permitting movement of the sample gathering member 30 outwardly from the rounded scraping edge 22 of the insertion tube 20 to expose the ferrules 34. The outer portion of the diaphragm 52, as shown in FIG. 3 extends to a point approximately even with the annular sealing surface 24 at the end of insertion tube 20. After the area to bev sampled is engaged and the cultures taken, the knurled section 50 is grasped and the stem 48 pulled outwardly at the end adjacent the seal container interlock 26, retracting the specimen gathering member 30 back into the tube and into the position shown in FIG. 2. The

specimen is contained within the sample holding chamber 40 in an airtight sealed configuration by the engagement of the outer periphery of the hemispherical member 32with the sealing surface 24 of the cylindrical insertion tube 20.

The container 12 is then placed over the insertion tube assembly 20 and its end seal groove 54 passed over the negative sloping sealing lip 28 of the seal con- OPERATION The invention is designed for use in gathering cells from the vaginal and cervical areas for cytologic evaluation, and is used for diagnosing in a manner similar to the commonly used Papanicolaou Smear test.

However, the invention can be used to gather samples from other remote portions of body cavities, such as the nose, ear and rectum. In each of these cases special adaptive configuration and sizes are assumed, but the basic principles are the same.

The preferred embodiment forconstruction of the spherical probe 30 is that of a low durometer reading rubber to permit insertion with the least discomfort. However, it is also contemplated that for mass production techniques, it would be desirable to use a suitably moldable type of soft resilient plastic for the construction of these devices.

It should be noted that the outer end annular surface 22 of the insertion tube 20 has rounded'edges to facilitate penetration and preclude any injury to internal organs. The ferrules 34 will give a scraping action with a slight rotary motion, so as to induce cells and specimen to accumulate thereon and possibly move back along the tapered surface to the narrow neck portion 42, prior to retraction of the specimen gathering member 30 to its initial position within the tube. I

The configuration of the diaphragm 38 is preferred, but it is understood that there may be some variation in this configuration to permit the hinging and moving action desired when the stem 48 is reciprocated.

The device, being designed for self-use in gathering specimen samples permits the cover container 12 to be readily removed by pulling it free from the insertion tube 20. The insertion tube 20 has a smooth exterior surface, and for use, surgical jelly is preferably applied thereto to provide lubrication when the insertion tube 20 is forced into the cavity and subsequently rotated.

pressed down into sealing engagement with the sealing flange section 26 of the insertion tube as shown in FIG. 2 and described above. The label 14 is then filled out and the entire assembly mailed to the laboratory for test and evaluation.

With regard to the identification system, it is also.

possible to provide a coded identification number for purposes of identification, so that the name of the person submitting the sample would remain anonymous. In this instance the identification number would be permanently imprinted or stencilled on the container tube.

It can readily be seen that the subject invention makes possible the use of a selt administered device which is of simple and cheap manufacture, permits the taking of samples in the privacy of ones home, and eliminates the need for trained medical personnel to take an accurate sample which can be sealed.

The parts themselves could be produced for substantially less than a dollar, and the pans could be sterilized and sealed to preclude infection.

While this invention has been described, it will be understood that it is capable of further modification, and this application is intended to cover any variations, uses and/or adaptations of the invention following in general, the principle of the invention and including such departures from the present disclosure as come within known or customary practice in the art to which the invention pertains, and as may be applied to the essential features hereinbefore set forth, as fall within the scope of the invention or the limits of the appended claims.
