Abstract

s p e c i f i c a t i o n To All Whom It May Concern:
Be it known that Hans Gram, citizen of Denmark, residing at 737, Strandvejen, Klampenborg, Denmark, has invented certain new and useful improvements in Vacuum Curettage Device, of which the following is a full, clear, and exact de-scription:
Abstract of the Disclosure:

A vacuum curettage device is described, comprising a cylindrical reservoir being fitted excentrically at one end with a curette, and having means for creating a vacuum therein. The reservoir has at least two compartments which can be brought to communicate one at a time with the cu-rette being fitted to a rotatable lid at one end of the reservoir, and each compartment has a filter partition to intercept solid particles removed by the curettage.

Description

1036~85 The present invention relates to a vacuum curettage device o~ the kind which is used for removing samples from the interior walls of body cavitles, particularly the cer-vix and the endometrium, by means of a curette, which is inserted in the body cavity in question, the said curette being excentrically fitted into a rotatable lid at one end of an elongated reservoir. This reservoir is adapted to have a vacuum hose connected and is ~itted with sieve means to separate solid particles removed by the curettage from lo liquid and mucus. The curette itself is of the known type comprising an elongated tubular shank having a rounded, closed tip and near this a lateral opening with a sharp edge for scraping. The shank may also have a small open-ing adjacent the reservoir. This opening is closed with a Pinger to create vacuum in the shank, and by partly lift-ing the finger, the vacuum in the shank can be reduced or totally released, when necessary during the curettage.

A disposable vacuum curettage device of this kind is ss~c~ ~nd)/ 9, /~7~
known from my US Patent No. 3,661,144A This known device is designed particularly Por scraping samples Prom the en-dometrium, However, in addition to taking samples from the endo-metrium, it has also been a general practice for several years to take samples from the cervix in order to disclose early stages of cancer. With the devices hitherto used for this sampling, however, collection of the removed material has proved difficult and often very incomplete. In order to carry out a mass investigation of women in the age groups, where the risk of cancer o~ the uterus is greatest, 3 according to experience, there is thus a need ~or cheap disposable devices being easy to use and ensuring an ef-

- 2 -036~5fective collection of the material removed from the cervix and the endometrium for successive testing.
q~he main object of the invention is to provide a dis-posable vacuum curettage device, which is cheap in manu-facture, and by means of which samples can be scraped fromthe cervix and from the endometrium consecutively in such a way that the samples are separately collected without risk of being infected either during the sampling or in ~ e,~
A the period until the samples can be ~rt~i~e~
lo Accordingly, the vacuum curettage device oP the inven-tion is comprising a curette including an elongated tubular shank having an inlet opening adjacent the outer end and being connected excentrically to a rotatable lid at one end of an elongated reservoir in the interior of which a vacuum can be created by fitting a vacuum hose to the re-servoir, the reservoir having at least two compartments communicating one at the time with the curette in appro-priate positions of the rotatable lid, each compartment being ~itted with a filter partition to intercept solid particles removed by the curettage.
In the use of the device, aPter fitting the vacuum hose, the curette is inserted in the cervix and scraping movements are made, the vacuum being relieved during inser-tion. Due to the vacuum, removed material passes through the curette and into the compartment of the reservoir in connect-ion with the curette at the moment.
The solid particles of the material are intercepted by the filter partition, the rest passing throu~h and be_ ing discarded.
When curettage of the cervix has been finished, the vacuum is relieved, and the lid of the reservoir is turned

- 3 -lQ36885 to connect the curette with another compartment of the re-servoir having a filter partition. I`he curette is then in-serted in the uterus to take samples ~`rom the endometrium, vacuurn being a~plied again. When this is finished, the va-cuum is again relieved, and the curette is withdrawn. Ifdesired, both of the sa~ple containing compartments can then be filled up with a liquid desin~ectant, e.g. form-alin, curette and vacuum hose can be removed, sterile caps or plugs being fitted over or into the openings, and the lo reservoir can be sent away for examination of the samples.
In a prePerred embodiment o~ the present device, the reservoir is cylindrical and divided into three compart-ments by means o~ axially extending partitions, each of said compartments having connection with a vacuum source, the three compartments being connectable one at a time with the curette by suitably turning the rotatable lid of the reservoir, and two of the compartments being fitted with a $ilter partition for interception of solid particles removed by the curettage. This allows for ~lushing the cu-rette to rinse and desinfect it between the two samplingsby connecting it with the compartment not having a filter partition and applying a vacuum to suck a liquid desinfec-tant through the vacuum line thus established.
The reservoir is preferably made from a suitable ther-moplastic material by injection moulding, and for easy andsimple moulding, the partitions dividing the reservoir are then made integral with the cylindrical outer wall and with a substantially Y-shaped cross-section.
In another embodiment of the present device, the cy-lindrical reservoir is closed at one endt the rotatablelid closing the other end, the vacuum hose being rernovably ' " ~'''`` 1036~S
connected to an outlet at the closed end, the latter hav-ing tubular projections inside the reservoir for receiv-ing and supporting tubular filter partitions inside two of the compartments of the reservoir. This is an inex-pensive manner of making the filter partitions, which are also easily removed when the samples are to be examined.
In a f`urther development of this embodiment of the present device, the closed end of the reservoir has an externally threaded cylindrical projection, onto which a lo funnel-like closure is screwed which loosely screwed on leaves open the connection between the vacuum hose and the compartments of the cylindrical reservoir, but when screwed tight disconnects such connection. This is advantageous in that the outlet to the vacuum hose can be stoppered before removing the hose, so that no risk of contamination exists here.
In another embodiment of the curettage device of the invention, one filter partition is of tubular shape con-axially mounted within the cylindrical reservoir, the lat-ter being closed at one end except for the connection tothe vacuum hose and having an insert or plug in the open end with a central bore to receive said tubular filter partition, and outside said central bore a smaller open passage to the inner of the cylindrical reservoir, and a larger passage partly surrounding the central bore and communicating with the interior of the cylindrical reser-voir through a filter partition, the curette being fitted excentrically into the rotatable lid so as to communicate with one or the other of the said passages.
In the following, the vacuum cure~tage device of the invention will be more fully described with reference to _ 5 _ 1036~85 the accompanying drawings, in which Fig. 1 is a side view of one embodiment of the device in substantially natural size, l~ig. 2 is a longitudinal section of the reservoir in a larger scale, Fig. 3 is a cross-section along the line III-III in ~ig. 2, Fig. 4 is a longitudinal section of another embodi-ment of the reservoir, and lo Fig. 5 is a cross-section o~ an insert in the reser-voir of Fig. 4.
The device shown in F'igs. 1-3 comprises a cylindrical reservoir 5 with a bottom 6 and a rotatable lid 7 with an excentrically placed connector 8 ~or receiving a curette 9 of known design.
At the closed end the reservoir 5 has a connector 10 which through a fitting 11 may be connected to a vacuum ; hose 12.
By means of partitions 13 and 14, the reservoir is divided into three compartments 15, 16, and 17, each of which can be made to communicate with the curette 9 by suitably turning the lid 7.
At the bottom of the compartments 15 and 16, the bot-tom 6 is ~itted with internal connectors 18 and 19 on which are mounted cylindrical filter walls 20 and 21 which are closed at the end adjacent to the lid 7.
Through passages 22, 23, and 24, the connectors 18 and 19 and the compartment 17 communicate with the inte-rior of the connector 10.
3 As suggested in Fig. 2, a loose cover 25 serves to close the connector 10, when the ~itting 11 is removed -~ ~036~s a~ter use of the device. Similarly, the rotatable lid 7 with the curette 9 is removed a~ter the use, being re-placed by a cover or stopper (not shown) to seal the com-partments. If desired, only the curette 9 is removed and its connector 8 stoppered.
With a view to the combined use of the device, the tip of the curette g can be fitted with a plastic cover having an opening and a scraping edge for the sampling of the cervix, the said cover to be removed before the curette lo is introduced into the uterus Por sampling.
In the embodiment shown in Figs. 4 and 5, the reser-voir 5 oP circular cylindrical shape has a closed bottom 6 with a centrally placed connector 30 for a vacuum hose (not shown). Coaxially with the cylindrical wall of the reservoir 5, a removable, tubular filter 31 is fitted within the reservoir, being held in place at the bottom 6 by the latter having an annular projection 32 around the connector 30 fitting into the tubular filter 31.
In the other end of the reservoir 5, a removable plug 33 is inserted, fitting tightly within the cylindrical wall oP the reservoir, and having a central passage 34 tightly enclosing the other end of the tubular filter 31.
The plug 33 has two separate passages 35 and 36 to the interior of the reservoir 5, the passage 35 being free, whereas the passage 36 is fitted with a filter partition 37 towards the interior or reservoir 5 to form a small compartment 38 in the plug 33.
At the end where the plug 33 is inserted, the cylin-drical outer wall of the reservoir 5 has an external 3 shoulder 39 serving as a locking means for the turned-in rim of a lid 40 made from a suitably elastic plastic ma-.

~0:~6885 terial to allow said rim to be pressed down over the shoulder 39. 'rhe lid 40 is thus rotatable with respect to the reservoir 5.
The lid 40 has an excentrically placed connector 8 for a curette 9, the passage through which is in continua-tion of one oP the passages 35 and 36, when the rotatable lid 40 is fitted to thereservoir 5 in a suitable position.
On the inner side, the lid 40 has a centrally dis-posed tubular projection 41, ~itting closely within the lo tubular Pilter 31, and aiding in keeping this filter in its proper place.
'l'he lid 40 may further be ~itted with an interior stop pin 42 extending into the passage 36 to limit the rotation of the lid. The pin 42 is placed in a position on the lid 40 to allow the operator of the device ,to shift from sucking through one of the passages 35 and 36 to the other without looking at the reservoir, the lid being turned until the pin 42 reaches one end of the passage 36, the latter extending over halP oP a circle around the central passage 34 og the plug 33.
