INTRAVAGINAL CATAMENIAL DEVICE FOR BLOOD LEAKAGE PREVENTION

Abstract: An intravaginal catamenial device (1) for prevention of leaking of menstrual blood composed of an absorbent member (3) and of an inflatable menstrual cup (2). The tampon absorbs menstrual blood while the inflatable menstrual cup (2) has the dual function, once inflated, of collecting menstrual blood within its cavity or reservoir (14) and of providing sealable closure of the vaginal canal for the prevention of exit through the vaginal orifice of menstrual blood escaped to the absorption of the tampon. By being inflatable, menstrual cup (2) allows an easy insertion and an easy removal of the device when deflated and it is also capable, upon extraction and disposal, of sealing off the blood collected, closing its opening (16) around tampon (3). The inflation of the menstrual cup (2) can be conveniently initiated during or just prior to insertion into the vagina by the user due to activation of a simple and safe chemical reaction which generates a gas such as CO2. The apparatus of inflation (10) is conveniently housed within inflatable menstrual cup (2). No external pneumatic sources are needed. Completion of inflation of the menstrual cup (2) occurs without operator intervention with the device already inserted into the vagina. Deflation of the menstrual cup (2) and extraction of the device from the vagina is carried out by the operator by pulling on a string (70) connected to the device. Pulling on the string (70), deflates the menstrual cup (2) and allows easy removal of the device. The device is user friendly, easy to insert and remove and comfortable to wear.

Description: INTRAVAGINAL CATAMENIAL DEVICE FOR BLOOD LEAKAGE PREVENTION TECHNICAL FIELD This invention relates to catamenial devices, more specifically to intravaginal catamenial devices. BACKGROUND ART Tampons are widely used intravaginal catamenial devices. Tampons are made of absorbing material and are inserted into the vagina by the female user at the time of the onset of the menstruation. Their purpose is to absorb menstrual blood delaying its exit from the vaginal orifice. Due to their absorbing properties, tampons, once inserted into the vagina, begin to absorb the blood they become in contact with, blood which outflows from the cervical os into the vagina. Tampons function as reservoirs aiming at delaying exit of the blood from the vaginal orifice conceivably until they become saturated with blood. However, regardless of their absorbency capabilities, tampons, for various reasons, are known to allow leakage of menstrual blood at rather unpredictable time generally after saturation but, not unusually prior to that, and at times shortly after insertion, falling short of providing the protection to the female user, protection which is the very reason for their indication and use. Blood may leak from the vaginal orifice because the tampon is too quickly saturated with blood or because the blood flow is disproportionately heavy for the absorbency capabilities of the inserted tampon or because the tampon does not provide an adequate sealing with the vaginal walls or with the vaginal orifice or for all the above reasons variously combined. No known tampon is capable of preventing leakage of blood from the vaginal orifice, regardless of shape, size, absorbency capabilities of the material or materials which they are made of. Despite the use of tampons, therefore, leakage of blood from the vaginal orifice is almost the rule during the days of the menstrual vaginal bleeding and its occurrence may result in a great deal of annoyance and inconvenience to the woman: leakage indeed actually defeats the main purpose for which tampons are used. Prior art deals with the problem of leakage of menstrual blood through the tampons in various way: some inventions by providing additional blood reservoirs to the tampons, some others by increasing the tampons absorbing capabilities by means of improved absorbing material, and others by using absorbing pads to apply in correspondence of the vaginal orifice to capture the blood escaped from the tampon. In all such cases, main object of the prior art is rather to minimize and possibly delay the outflow of blood, rather than reliably preventing the leakage of blood until it is the appropriate time for the woman, as determined by the woman rather than by her endometrium, to permit exit of the menstrual blood from the vaginal orifice. Zadini et al. disclose in their US patent 5,674,239 a catamenial device composed of an intravaginal absorbent member associated with an inflatable member or balloon. This catamenial device appears to effectively prevent blood exit from the vaginal orifice. Indeed the balloon when inflated sealingly engages the vaginal walls obstructing the lumen of the vaginal canal . The balloon is inflated by the user via an external pneumatic source such as a syringe, a minibladder or in general an external pneumatic device connected to the balloon via an adapter, with or without an interposed hollow conduit. While undoubtedly this catamenial device represents an improvement with respect to the various types of intravaginal tampons currently in use due the fact that the balloon, once inflated appears effectively to prevent leaking of the menstrual blood escaped to the absorption of the tampon, yet this catamenial device has a significant drawback. This drawback lies on the fact that the female user in order to inflate the balloon has to carry out few operational steps which renders the device user unfriendly, being said operational steps time consuming, somehow elaborated and requiring some practice. Ultimately the mere fact that the user has to carry out unavoidable operational steps for the actuation and use of the device, may discourage the use of the device itself by the menstruating woman. These operational steps for the inflation of the balloon include connection of an external pneumatic source with the deflated balloon via an adapter with or without the interposition of a hollow conduit, manual operation of inflation by the user acting upon the pneumatic source and disconnection of the pneumatic source or conduit from the balloon once the balloon is fully inflated. The following miniaturized structures are required to carry out the inflation of the balloon: an external pneumatic source with or without a conduit connected to it, an adapter connected to the pneumatic source or to the conduit, a unidirectional valve in the balloon in order to avoid escape of air from the balloon once the balloon is fully inflated. All these miniaturized components add complexity to the device and with complexity cost to the design. BRIEF SUMMARY AND ADVANTAGES OF THE INVENTION The present invention seeks to provide the female user with an intravaginal catamenial device that effectively prevents menstrual blood leakage and that at the same time is very easy to operate and comfortable to the user. In accordance with this invention, this object is accomplished in a catamenial device for intravaginal use which comprises a substantially impermeable member or balloon capable of self-inflating, combined with an absorbent member. The inflatable impermeable member is inflated by pneumatic means of inflation which are fully housed and operational within the inflatable member itself. No external pneumatic sources are needed, nor conduits nor adapters nor unidirectional valves. This catamenial device composed of a self-inflatable impermeable balloon and of an absorbent member is easily operated, comfortable to wear and easy to remove. The inflatable member can be shaped in various forms and can be arranged with tampons in a number of ways. The inflation of the balloon is simply actuated by the female user via gently pressing between the fingers a segment of the balloon prior to insertion or at nearly accomplished insertion of the device inside the vagina. The act of squeezing a segment of the balloon actuates the self-inflation mechanism of the balloon, mechanism entirely contained and self sufficient within the device. Deployment of the balloon inside the vagina effectively prevents blood leakage. Indeed the balloon once inflated within the vaginal canal seals the vaginal canal. Absorption of menstrual blood is carried out by the absorbent member while the self- inflatable member provides sealable closure of the vaginal canal not allowing exit from the vaginal orifice of the menstrual blood escaped to absorption. Vaginal closure is achieved by the inflatable member impermeable to fluids, easily self-adaptable to the variability of size and shape of the vaginal lumen and to the variability of smoothness of the vaginal walls, said inflatable member expanding to exert a gentle pressure on the vaginal mucosa, such a pressure being sufficient to prevent passage of blood between the inflatable member itself and the vaginal mucosa. This catamenial device provides the user with an effective degree of protection from blood leakage during the menstrual cycle. Removal of the device from the vagina is simple and void of any discomfort for the user. Removal is in all similar to the removal of an ordinary tampon without a balloon. The female user pulls on the string connected to the device causing the gas to escape from the balloon with a resulting deflation of the balloon. The deflated balloon and tampon are removed without difficulty. In a preferred embodiment a balloon is provided with a self sealable closure around the absorbent member to prevent spillage of blood on removal.

The device, generally indicated at 1, is composed of an inflatable or expandable cup or member or means or balloon 2 shown in a deflated status in Fig. 2 and an absorbent member or tampon 3, better shown, alone, without inflatable cup 2 in Fig.l. Balloon 2 is cup-shaped or inverted dome shaped and is made of a material substantially impervious to gasses and fluids. Absorbent member 3 is coaxial with inflatable cup 2, being encircled completely or partially by inflatable cup 2. String 70 is sealingly connected to inferior pole 61 of balloon 2 and it is also connected to inferior pole 4 of tampon 3. Details of the connection of string 70 with balloon 2 and tampon 3 will be described below. As best seen in Fig. 3, 4, 6 which are cross sections of device 1 at different stages of operation, respectively Fig. 3 and 4 with inflatable cup 2 in a deflated status and Fig. 6 with inflatable cup 2 fully inflated, inflatable cup 2 is made of two generally cup shaped thin sheets, internal cup-shaped sheet or membrane 74, and external cup-shaped sheet or membrane 74', which are invaginated one within the other and superiorly are sealed to each other along circular rim 16 to form cup shaped inflatable member or balloon 2. Cup shaped member or balloon 2 with its internal membrane 74 delimits reservoir or concavity or collecting means 14 as best seen in Fig. 5 providing a collection site for the menstrual blood. Internal membrane 74 is preferably made of substantially noncompliant, inextensible material while external membrane 74' is preferably made of compliant or resilient material, both membrane 74 and 74' being substantially impermeable to gasses and fluids. As best shown in Fig. 3, 5, 6, membrane 74 and 74' are sealingly adherent together along circular ribs or circular sealed segment 24 creating therefore chambers 10, which become donut shaped once balloon 2 is inflated. Chambers 10 are in flow communication with each other via conduits 28 which are formed from linear interruptions of sheet adhesion along circular ribs 24 as seen in fig 6. Sealing adhesion of membrane 74 and 74' along circular ribs 24 can be obtained for example by thermally fusing internal membrane 74 with external membrane 74' at regular intervals. Chambers 10 are also in flow communication inferiorly with lower or bottom chamber 72. Inflatable cup shaped member or balloon 2 is formed superiorly with circular opening or mouth 8 delimited by circular rim 16 and inferiorly has pole 61 to which string 70 is connected and sealingly exits from balloon 2 as above described. As shown in Fig. 3, 4, 6 which, as above described, are cross sectional views of device 1 at different stage of operation, lower or bottom chamber 72 is delimited laterally and inferiorly by external sheet 74', superiorly by internal sheet 74 in correspondence of the cul de sac of reservoir 14. Chamber 72 is in flow communication with chambers 10 as best shown in Fig. 3 via conduits 28. As better shown in Fig.4, within chamber 72, string 70 firmly adheres via segment 9 to external sheet 74' of lower chamber 72 and transverses slackly, with few loops free of adherence, lower chamber 72 of balloon 2 to firmly connect to inferior pole 4 of tampon 3. Details of different arrangement of the connection of string 70 with balloon 2 and tampon 3 are described below and illustrated in Fig. 8, 9, 10. As better shown in Fig.4, apparatus of inflation or pneumatic means 10' is fully housed within chamber 72. Lower chamber 72 houses bladder 12 having wall 111' made of material substantially impermeable to fluids, bladder 12 containing an acidic fluid solution 90, such as a solution of citric acid or malic acid or acetic acid or any other suitable acidic solution or suitable chemicals or reagents. Lower chamber 72 houses also in a disperse fashion effervescent substrate 89 such as sodium bicarbonate or any other suitable substrate or chemicals or reagents mixable with the acidic solution 90 contained within bladder 12 to generate gas such as CO2 when mixed together. Other types of solution and other type of substrates capable of generating a suitable gas means for the purpose of inflating balloon 2 can be used. In operation the female user, while inserting device 1 into the vagina or just prior to use, presses between her fingers lower chamber 72 squeezing bladder 12 to the point of rupturing its wall 111' which will result in exiting of acidic solution 90 from bladder 12 and into its mixing with substrate 89. The mixing of acidic solution 90 with effervescent substrate 89 dispersed within chamber 72 generates CO2 which inflates inflatable cup 2. In Fig. 5 inflatable cup 2 is shown fully inflated. With inflatable cup 2 fully inflated, device 1 is fully operational. Tampon 3 will absorbs menstrual blood while inflatable cup 2, once fully inflated seals the vaginal canal not allowing passage of blood between external sheet 74' of balloon 2 and the vaginal walls. No blood will exit from the vaginal orifice. Inflatable cup 2 when fully inflated will collect blood within reservoir 14. Once the user determines to remove the device, she will pull on string 70. The pulling of string 70 will cut through exterior wall 74' as segment 9 of string 70 is firmly adherent to external sheet 74' in lower chamber 72, creating a slit in chamber 72 of inflatable cup 2 through which CO2 or other suitable gas can escape resulting in deflation of balloon 2. Device 1 with inflatable cup 2 now deflated can be easily removed by the user by further pulling on string 70. On extraction of device 1 from the vagina, rim 16 of inflatable member 2, due the intrinsic resilient properties of membrane 74' will centripetally retract closing circular opening 8 around tampon 3 not allowing any spillage of blood collected within reservoir 14 upon extraction. Fig. 8 shows an alternative type of apparatus of internal pneumatic source of inflation to apparatus 10' illustrated in Fig. 4. This apparatus is also housed in lower or bottom chamber 72 of inflatable cup member 2. In this apparatus, bladder 67 preferably adheres to inferior segment 77 of wall or membrane 74 and has internal breakable membrane or diaphragm 82 made of material less resistant to pressure than the material of wall 111, separating upper compartment 81 from lower compartment 87 of bladder 67. Upper compartment 81 contains acidic fluid solution 90 and lower compartment 87 contains effervescent substrate 89. String 70 is anchored via segment 70' to inferior segment 77 of wall or membrane 74 of inflatable cup 2, slackly traverses lower chamber 72 to adhere via segment 70" to internal surface of exterior wall 74' of bottom chamber 72 and sealingly exits through exterior wall 74' in proximity of pole 61 of inflatable cup 2. In use, the female user, while inserting device 1 into the vagina or just prior to use, compresses bladder 67 between her fingers. Since closed upper compartment 81 of bladder 67 is filled with fluids, the pressure applied upon it will result into rupture of membrane 82 which is made of less resistant material than wall 111 of bladder 67. Rupture of membrane 82 allows mixing of acidic solution 90 with effervescent substrate 89. Upon mixing of acidic solution 90 with substrate 89, CO2 or any other suitable gas will be generated. Being wall 111 of bladder 67, or at least the portion of wall 111 which delimits lower compartment of bladder 67, made of material permeable to gasses, CO2 or the generated gas will enter lower chamber 72 and diffuse into the space delimited by internal membrane 74 and 74'. Inflatable cup 2 will inflate up to sealingly engage the wall of the vagina. Device 1 fully inflated will appear as shown in Figures 5 and 6. As already mentioned above blood flowing from the cervical os will be collected within reservoir 14 of inflatable cup 2 and no leakage of blood will occur from the vaginal orifice due to the fact that external membrane 74' will adhere to the vaginal wall exerting sufficient pressure to sealingly engage the vaginal wall. Once the female user wants to extract cup shaped member 2 from the vagina she will pull on string 70. The pulling of string 70 will cut through external wall 74' creating a slit through which CO2 or other suitable gas can escape resulting into deflation of balloon 2. Due to the impermeability to fluids of wall of bladder 67, the eventual residual acidic solution and substrate will remain within bladder 67 and will not be spilled into the vagina. Fig. 9 shows yet an alternative form of an inflating apparatus for the mixing of acidic solution 90 with substrate 89. This apparatus is in all similar to inflating apparatus of Fig.8, except for an additional element, string 105. String 105 is firmly attached to membrane 82 along a diameter of said membrane 82, traverses lower chamber 72 to sealingly exits through invaginated portion 107 of exterior wall 74'. In use, the female user ruptures membrane 82 by pulling on string 105, which upon traction will cut through membrane 82 creating a slit which leads to mixing of acidic solution 90 with substrate 89. Subsequent steps are identical as for the device with inflating apparatus shown in Fig.8. Fig.10 shows yet an alternative type of apparatus of internal pneumatic source of inflation in all similar to the apparatus illustrated in Fig. 8 with the following differences. Acidic solution 90 and substrate 89 are no longer present. Bladder 67 of Fig. 8 and 9 is replaced by capsule 67' which is void of membrane 82. Bladder 67' has wall 113 and a weaker portion 112 of said wall, positioned in correspondence of pointed puncher 86. Wall 113 of capsule 67' is made of material impermeable to gasses and contains compressed pneumatic means or gas 110, such as CO2 or air. Perforating puncher 86 is attached via flexible arm 86' to the wall of capsule 67', as clearly shown in Fig. 10. In use, the female user while inserting the device into the vagina or just prior to use, will press on inferior pole 61 of wall 74' to puncture membrane 112 of capsule 67' and permit passage of gas 110 or other suitable gas from capsule 67' into lower or bottom chamber 72 and from there inside the reminder of inflatable member or cup 2 to inflate inflatable cup 2 up to sealingly engage the wall of the vagina. Any of the above described apparatuses of inflation can be located in an extroflexion or appendix of balloon 2, located within a recess of the tampon. Activation of the inflation mechanism such as the squeezing of the bladder containing the acidic solution may occur via the interposed absorbent material of the tampon. Figures 11 and 12 show an alternative form of device 1 of Fig. 1 through 10. In this device, generally indicated at 100, cup-shaped internal sheet or membrane 84 is invaginated within cup-shaped external sheet or membrane 84' of cup-shaped member or balloon 62 and the two sheet are sealed together along rim 16' precisely as internal sheet 74 is invaginated within external sheet 74' and the two sheet are sealed together in device 1. However, in device 100 of Figures 11 and 12 sheet 84 and 84' are sealingly adherent to each other not in a circular horizontal fashion as in device 1 described in Fig. 1 to 10 but in a radial vertical fashion through radial vertical sealed segments or ribs 66 grossly parallel and evenly spaced, creating therefore radial vertically oriented chambers 65 stemming from bottom chamber 72' with which they are in flow communication. Chambers 65 are superiorly in flow communication with chamber 64 which becomes donut-shaped once balloon 62 is inflated. As for device 1, balloon 62, when inflated, delimits concavity or collecting means or reservoir 14 for collection of menstrual blood escaped to absorption of absorbent member 3. As shown in Fig.12, at the time of extraction from the vagina donut-shaped member 64 will circularly retract around tampon 3 not allowing exit of blood collected within reservoir 14, avoiding spillage of blood upon extraction of the device from the vagina. Other cup-shaped versions of device 100 of Figures 11 and 12 can be obtained by sealed adhesion of sheet 84 and 84' along variously oriented lines or in correspondence of islands or points. Fig. 13 shows an alternative form of the device 1 of Fig.l to 10. A cross sectional view of this device and of the female pelvis are shown in Fig. 13. This device generally indicated at 5 is much similar to device 1 of Fig. 1 to 10 except that inflatable member or balloon 2' is no longer cup shaped but it is of generally spherical/ovoid shape lacking therefore of a reservoir or collecting cavity or means for collection of menstrual blood. Balloon 2' is positioned posteriorly to tampon or absorbent member 3. Not shown in Fig.13, within balloon 2' is housed any one of the pneumatic internal apparatuses described for device 1 in Fig. 4 and Figures 8, 9 and 10. Tampon 3 is connected to balloon 2' for instance with a string not shown in Fig.13. The device is used exactly as device 1. When inflated, balloon 2' will adhere to wall 33 of vagina 30 sealing the vaginal canal . Absorbent member 3 will absorb blood while balloon 2' will not allow exit of blood escaped from absorbent member 3 from orifice 32 of vagina 30. Deflation of balloon 2' and subsequent removal of the device is carried out in the same fashion as in device 1 of Fig. 1 through 10 by the user pulling on string 70. Fig.14 shows an alternative form of the device 1 of Fig.l to 10. This device generally indicated at 30' is much similar to device 1 of Fig.l to 10 except that cup shaped member or balloon 2" when inflated tightly encircles tampon 3, the device lacking therefore of a reservoir for collection of blood. As in cup-shaped balloon 2 of device 1 of Fig. 1 through 10, cup-shaped balloon 2" of device 30' has an internal sheet not shown in Fig.14 correspondent to cup-shaped internal sheet 74 of balloon 2 of device 1 of Fig. 1 through 10 and an external sheet indicated at 94' in Fig. 14. In this version internal sheet of balloon 2" and external sheet 94' are sealingly adherent along one single horizontal rib, indicated at 60, to form upper chamber 32 which takes the shape of a donut when inflated, although the two sheet could be sealingly adherent along multiple ribs to form a number of communicating donuts as in device 1 of Fig. 1 through 10 or may be sealingly adherent in points or along variously oriented lines. Below horizontal circular line of adhesion or rib 60, lower or bottom chamber 13, as lower or bottom chamber 72 of device 1 of Fig. 1 through 10, is delimited by an internal sheet, not shown in Fig. 14, equivalent to internal sheet 74 of device 1 of Fig. 4, and by external sheet 94', equivalent to sheet 74' of device 1 of Fig. 4. The internal sheet and external sheet 94' are preferably made of non compliant, inextensible material, while donut-shaped upper chamber 32 is preferably made of compliant, resilient material. As for device 1, lower chamber 13 houses any of the inflating apparatuses described for Fig. 1 to 10. Insertion of this device, inflation, deflation of balloon 2" and extraction of the device are exactly the same as for device 1 of Fig.l to 10. In all above disclosed intravaginal catamenial devices, the inflatable member is inflated via pneumatic means housed within the inflatable member. No external pneumatic sources of inflation are present nor needed to inflate the balloon as the apparatuses of inflation are housed and operationally self-sufficient within the various types of balloons.
