SHEET 2 OF 2 INVENTOR.

BYW 4 ATTORNEY METHOD AND DEVICE FOR BIOPSY SPECIMEN COLLECTING AND HANDLING The present invention relates to the processing of samples of cellular material collected from body cavities for microscopic examination and to apparatus for the collection of such samples.

In my copending application, Ser. No. 199,373 filed June 1, 1962, now abandoned, there is described a method and apparatus for obtaining and processing samples of cellular material from body cavities for microscopic examination which permits the use of untrained personnel to procure such samples. While the method and apparatus described in my copending application are eminently satisfactory for the purpose, microscopic slides prepared from such samples do not invariably contain as high a positive cell count as is usually desired by pathologists.

It is a purpose of the present invention to provide a method which enables individual cell specimens to be processed safely without the danger of cross-contamination.

It is a further purpose of the invention to provide a method which enables the use of the same apparatus for the entire processing whereby the danger of cross-contamination is avoided.

It is a further purpose of the invention to provide a method which enables all the-necessary steps to be accomplished by means of one single apparatus, thereby obviating the necessity of multiple pipettes, aspiring syringes, collection bottles, etc.

It is a further purpose of the invention to provide a method which eliminates the need for using and washing multiple items of laboratory equipment.

It is a further purpose of the invention to provide a method which expedites the processing and cuts down the time required in the laboratory.

Still a further purpose of the invention is to provide the method which enables improvement of the quality of the microscopic preparations and thereby renders the microscopic examination more rapid and accurate.

It is a further purpose of the present method to provide means of effecting a specific cellular sampling from the squamocolumnar juncture of the cervix, irrespective of normal anatomic variations.

It is a further purpose of the present method to eliminate the need for spreading and fixation of the cellular material on a microscopic slide at the time of collection, thus simplifying the procurement of the sample.

It is a further purpose of the present method to secure a richer sample of atypical or positive cells for analysis than heretofore possible to recover and concentrate on a single microscopic slide in the laboratory.

It is a further purpose of the present method to assure a random mixture of atypical and positive cells with the normal cells on the microscopic slide, so that the probability of any individual microscopic field containing diagnostic cells is greatly increased.

It is a further purpose of the present method to assure fixation and distribution of the cellular material under laboratory control, so as to assure greater uniformity and quality of the microscopic preparations.

It is a further purpose of the invention to provide an apparatus for carrying out the method.

Among other purposes of the invention one purpose is to provide an apparatus which enables the utilization of a single container structure as a collecting as well as shipping and processing container.

Still a further purpose of the invention is to provide apparatus for the purpose specified, a part of which can be used as a centrifugal container for processing the sample material and another part of which can be used as a pipette for aspiring material from said centrifugal container and distributing the material directly on a microscopic slide.

Further purposes of the invention will appear from the following specification in connection with the accompanying drawing, in which FIG. 1 is a perspective view of one embodiment of the pipette of the invention,

The invention provides a method for procuring and processing samples of cellular material by utilizing a single container structure which comprises the steps of effectively obtaining cellular material from a body cavity, washing said cellular material into said container structure, shipping said container structure to a laboratory for processing said cellular material exclusively within said container structure to condition said cellular material for microscopic examination, and eventually distributing said cellular material on a microscope slide directly from said container structure.

More specifically the invention provides a method for procuring and conditioning samples of cellular material for microscopic inspection by means of a single container structure which includes pipette means comprising the steps of collecting cellular material such as from a body cavity of a human being, washing said cellular material from the collecting means into said container by means of a solution within said container, shipping said container and pipette structure with the solution contained therein to a laboratory, processing said solution by centrifuging or sedimenting within said container structure to effectively condition the cellular material contained in said solution for microscopic examination, and eventually distributing said cellular material directly from said container by means of said pipette means on a microscope slide.

The invention provides apparatus for procuring and processing samples of cellular material by means of a swab or scraper which comprises first means effectively providing a container for a fluid, second means effectively providing a swab or scraper for the collection of cellular material and a third means effectively providing a pipette structure having a bulb and tubular portion. Said container, said swab or scraper and said pipette structure are assembled in a manner to provide easy separation so as to render the container operable as a centrifuge tube for processing the cellular material and conditioning said cellular material for microscopic examination. The structure also includes means operable to render said tube effective as a pipette for the withdrawal of cellular material from said centrifuge tube.

Referring now to the accompanying drawing, and specifically to FIGS. 1 through 4, the container structure is outwardly formed in three parts, a liquid container 16 which also effectively provides a centrifuge tube, a tubular structure 7 which effectively provides a pipette tube and a cap I which effectively provides a pipette bulb.

One end of tubular structure 7 is provided with a flange 9 having extending from it a tubular portion 10. Tubular portion 10 is detachably inserted into the open end of container 16 to form a liquidtight fit. The liquidtight fit may be provided by any conventional means, such as a force fit, heat sealing or gluing. The other end of tubular structure 7 is desirably provided with two circumferential ridges 12 and 13 which are spaced from the other end of the tubular structure and from each other. The cap 1 detachably covers the end of tubular structure 7 and desirably may be internally provided with circumferential recesses 4 and which are spaced from one another to provide a liquidtight fit when circumferential ridges 12 and 13 snap into them.

A swab structure of the type illustrated in FIG. 3 is provided for the collection of cellular samples. The swab structure is an elongated member 20 having attached at one end a soft flexible material and at the other end appropriate means for detachably assembling the swab structure to the tubular structure 7. The soft flexible material may be any appropriate material such as rayon, cotton or a foamed plastic such as polyurethane foam. As illustrated, the soft flexible material is a tube 24 of polyurethane foam, closed at one end. The soft flexible material may be attached to the elongated member by any appropriate means, so long as it is prevented from becoming detached. Again as illustrated, in FIG. 3, the attachment is accomplished with a toothed member 21 which permits the sleeve 24 to freely slide thereover, but which prevents it from being removed. At the other end of the elongated member 20 there is provided means for detachably attaching the swab assembly 19 to the tubular structure 7. This may be accomplished by any appropriate means. One manner of attaching the swab assembly 19 to the tubular structure 7 is to provide one end of said swab assembly with footed prongs 22 which are circumferentially arranged around the elongated member 20, said footed prongs being of sufficient length to fit snugly into the cavity of the hub of the tubular structure 7. To prevent the dislodgement of the swab assembly 19 during use, it is desirable to provide an extension 23 at the pronged end of the swab assembly, which extension 23 fits into the cannula of tube 8.

The method of procuring and processing cellular material is as follows:

The seal between the tubular structure 7 and the container 16 is broken in the manner shown in FIG. 7. Cellular samples are taken from the site to be examined by swabbing the site as shown in FIG. 8, in which case the site examined is the cervix The cellular material is then washed from the swab into the container 16 as shown in FIG. 9. The cellular material is concentrated in the container 16, preferably by centrifugation. The supernatant solution is removed, as by decanting and a fixing solution is placed in the container 16 and is mixed with the cellular material. The cellular material can be further processed by:

a. separation from the supernatant fixing solution, by sedimentation or centrifugation, and distribution on a microscope slide for examination of further processing or b. by the addition of staining agents to the container 16; further processing may be carried out directly prior to the examination of the material.

The structure of the present invention provides a single unit, the components of which serve all of the apparatus necessary to collect, contain and process cellular material without the danger of cross-contamination.

The structure is delivered to the physician prefilled with a preservative solution. Cellular material can be collected by the physical and is either processed and examined immediately by the physician or shipped in the structure to a laboratory for processing and examination.

FIGS. 5 and 6 illustrate a modification of the cap 1 wherein the cap is provided with an internal nib 6 which depends from the inner end of said cap. The nib is such diameter that when the cap I is fitted over the end of the tubular member 8, the nib enters the opening and forms a liquidtight seal, thus preventing leakage ofthe liquid.

A modification of the invention is shown in FIGS. 11 and 12. In this embodiment of the invention, the swab assembly 19 is replaced by the scraper assembly 119. Scraper assembly 119 is an elongated member 120 having at one end a flattened rigid scraper 124 which is adapted to collect cellular material from the anterior and posterior lips of the cervix and from the external os. The scraper 124 is attached to prongs 122 by a shank 120. The shank extends beyond prongs 122 to form an axial rod 123. The prongs 122 are of such dimension to form a snug fit in the hub 110, with the axial rod 123 extending into cannula 111 of tube 108 to help provide stability. The method of taking a scraping with the scraper assembly 119 is illustrated in FIG. 12.

The device of the invention is used not only to collect cellular samples, but is also to process the samples and to prepare the microscope slides.

After obtaining the sample, the swab 24 or the scraper 124 is washed in the fluid 18 which is contained in container 16, to remove the cellular material from the swab or scraper. The container is then placed in a standard centrifuge and the cells are concentrated at the bottom of the container 16. The supernatant fluid is decanted and a fixing solution is admixed with the cellular material in container 16. The mixture is recentrifuged to again concentrate the cellular material in the bottom of container 16.

Cap 1 is then inserted into hub 10 end of pipette assembly 7 so as to form a pipette.

As shown in FIG. 10, the thus formed pipette is used to suck the cellular material out of container 16. The cellular material is placed onto a microscope slide 26 by squeezing cap 1.

The distribution of the cellular material on microscope slide 26 is accomplished as illustrated in FIG. 13. The cellular sample is distributed in the form of an even layer because of the circumferential ridges l2 and 13 on tube 8 which permit the surface of the portion 14 to be spaced from the surface of the microscope slide a distance which is substantially that of the desired thickness of the sample layer.

Obtaining cellular samples by routine spatula scraping has the advantage of permitting the preparation of a microscope slide from a specific site under direct vision. For example, the usual site of early cervical cancer is the squamocolumnar juncture, accessible to routine spatula collections. But the juncture may be withdrawn into the cervical canal, routine wooden spatula scraping may be ineffective to obtain samples from this site. The collapsible nature of the swab or sponge modification and the present invention permits introduction of the collecting surface of the present device into the cervical canal, to obtain good samples even in the face of such anatomic variations.

A further embodiment of the invention is useful for obtaining cellular samples to include cells exfolicting from still higher levels. This modification is illustrated in FIGS. 14 and 15 wherein the shank 20 of swab assembly 19 has disposed at one end thereof channels 225 extending through mount 22. By substituting this swab assembly for the swab assembly shown in FIG. 2, the device may be used first to irrigate the body cavity from which the cellular material is to be obtained in order to wash out the cells from the cavity, and then the device is used as hereinbefore described to obtain samples by swabbing or scraping.

Irrigation is accomplished by removing the cap I from the pipette 7, inserting the tubular member 8 into the vagina until only the container 16 is exposed, squeezing the container 16 to eject the irrigating solution, releasing the pressure on the container to reaspirate the irrigating solution together with cellular material suspended in the solution. If desired, the irrigation can be repeated several times. After completion of the irrigation, additional cellular material may be obtained by swabbing or scraping.

It will be appreciated that for the irrigation procedure, the container 16 must be formed of a resilient, flexible material. The cap I should be formed ofa similar material.

The solution with which container 16 is prefilled, where to be used as an irrigating solution must be capable of such use without injury to body tissue. It must also be capable of inhibiting decomposition of the cellular material; however obtained. I

l have found that a suitable solution for use with my invention comprises a mixture of alcohol and physiological salts to which has been added a small amount of a fungicide or antibiotic. The saline concentration should be sufficient to prevent the cells from swelling or shrinking. The alcohol concentration should be high enough to inhibit bacterial growth and/or decomposition of the cellular material, but low enough not to injure the patient or alter the cells in such a manner as to make further processing difficult. The concentration of the fungicide or antibiotic should be sufficient to ensure against decomposition of the solution on prolonged storage.
