11 Claims, 18 Drawing Figures NASAL TAMPON This application is a continuation-in-part of my application Serial No. 224,172, filed February 7, 1972, now abandoned.

This invention relates to a self-retaining nasal or nasopharyngal tampon, and is particularly concemed with a tampon of the above type which can be readily inserted into the nasal passage to control nasal hemorrhaging without the need of packing the nose with gauze, and which includes one or a plurality of inflat able members which can be readily inflated selectively when the device is inserted into the nasal passage, the inflatable members when inflated in the form of a bag or balloon functioning to fill the nasal cavity and supplying the necessary pressure for hemostasis, and particularly including self-sustaining means provided at one end of the tube and adapted to anchor the tube in the nasal passage so that the tube remains in fixed position in the nasal passage when the inflatable member or members are either in the deflated or the inflated condition.

Inflatable bag catheters employed in various body drainage procedures are well known in the art, employing various techniques for inflation of such catheters for retention in their proper position in the body region in which they are placed.

However, a particular need has arisen for a relatively simple nasal tampon for use in controlling nasal hemorrhaging and post-adenoidectomy bleeding, which can be employed without the need of packing the nose with gauze, and which tampon can be readily inserted into the nasal passage and can be quickly and easily inflated to form one or more balloons which fill the nasal cavity and/or the nasopharynx to supply the necessary pressure for hemostasis, and including means to retain the tampon in the nasal passage and/or the nasopharynx for any desired period, and which balloonor balloons can be readily deflated as desired for easy and painless removal from the nasal cavity.

An improved nasal tampon achieving the above requirements is disclosed in my US. Pat. No. 3,570,494. According-to the'patent, there is provided a nasal tampon comprising an elongated flexible, e.g. rubber'tube, a plurality of inflatable sleeves sealingly surrounding the tube, at least one such inflatable sleeve located adjacent the outer closed end of the tube and one such inflatable sleeve adjacent the open inner end of the tube, with passage means between the interior of the tube and each of the inflatable sleeves for selective inflation thereof.

Although the above-noted nasal tampon of my patent has proved highly effective in practice, it has been found that the danger exists that in the event the inflatable member or sleeve positioned at the inner end of the tube and which in the inflated position serves to anchor the device by contact with the exterior of the nostrils, becomes deflated; for example by accident, or when the device is to be removed from the nasal passage, the patient may aspirate the device.

As a particular feature of the present invention, in order to overcome and avoid such possible danger of aspirating the device, there is provided adjacent the open end of the tube in place of the inflatable anchoring member of the device of my above patent, a hollow self-sustaining bulb formed on the tube and which at all times, by contact with the outside of the nose adjacent the nostrils-maintains the nasal tampon in fixed position after being inserted into the nasal passage, whether or not the inflatable member or members sealingly attached around the outer closed end of the tube, and also around the intermediate portion of the tube, are in the inflated operative position within the nasal passage,

or are in the deflated position, for example, following deflation thereof and preparatory to removal of the device from the nasal passage. Such bulb according to the preferred embodiment is mounted integral with the tube, as by molding thereof on the tube.

The provision of such anchoring means in the form of the above-noted bulb, which is semi-rigid and has a substantially larger diameter than the diameter of the tube, avoids all danger of the patient inadvertently aspirating the device when it is inserted into the nasal passage, either beforeor after the inflatable member or members also carried on the tube have been inflated into their operative position.

According to the present invention, there is thus pro vided according to one embodiment, a nasal tampon comprising an elongated flexible tube open at one end and closed at its opposite end, the above-noted hollow bulb carried on the tube adjacent the open end thereof, an inflatable member or sleeve surrounding and sealingly attached around the closed outer end of the tube, passage means communicating the interior of the tube with the inflatable member to permit inflation thereof by fluid introduced into the tube and the inflatable member via the passage means, when the device is disposed within the nasal passage, and sealing means, eg in the form of a soft rubber plug, positioned within the tube, preferably adjacent the open end thereof, such plug being capable of being punctured as by the needle of a syringe, for inflating the inflatable member, and being resealable upon removal of the needle. Puncture of such rubber plug by the syringe needle permits introduction of inflating fluid via the passage means located in the wall of the flexible tube, into the inflatable sleeve to permit inflation of the rubber plug by the syringe needle and withdrawal of fluid from such sleeve.

' According to another embodiment, a second inflatable member is sealingly attached to the tube and disposed around the flexible tube intermediate the ends thereof and between the above-noted first mentioned inflatable member disposed around the closed outer end of the tube, and the bulb, passage means communicating the interior of the tube and the second inflatable member to permit inflation thereof by fluid introduced into the second inflatable member, and a second sealing means, e.g. in the form of a soft rubber plug also po- 1 sitioned within the tube and spaced from the abovenoted first mentioned sealing means or plug, such second plug also being capable of being punctured by asyringe needle, the respective sealing means permitting selective inflation and deflation of the two inflatable members.

According to a preferred modification, particularly employed when the device carries a plurality, e.g. two, inflatable members, there is also provided an insert for introduction into the inner end of the tube, such insert containing channels, with the sealing means, e.g. soft rubber plugs, inserted into such channels, the sleeve also containing passageways registering with the passage means in the tube, such passageways communicating with the respective inflatable members via the passage means thereto in the wall of the elongated tube.

Such insert is beneficial,particularly where there are a plurality of sealing means in the form of softrubber plugs which are to be punctured by the syringe needle,-

to prevent inadvertent puncture of the wall of the inflatable tube by the needle of the syringe when it is passed into and withdrawn from each of the respective plugs for inflation or deflation of the respective inflatable members. Such insert can be of the type shown and described in my above patent.

The invention will be more clearly understood by reference to the description below of the various embodiments of the invention, taken in connection with the accompanying drawing wherein:

end of tube 10 a hollowsymmetrical bulb 14 is provided, thebulb 14 having a substantially larger diameter than the diameter of thetube 10, and being semirigid. The size or outer diameter of the bulb is such that it will function to securely anchor the device when inserted in the nose cavity, the bulb serving as an anchor against the under surface of the nose adjacent the nostrils as described in detail below. Thus, for example, the outer diameter oftube 10 can be inch and the outer diameter ofbulb 14 can be about inch, but it will be understood that these dimensions are only exemplary and in no way limiting. Such bulb, as shown in FIG. 2, preferably is integral with the tube itself, as by molding such bulb on the tube during fabrication thereof, so that the bulb is preferably semi-rigid.

Thus, one of theinflatable members 12 is positioned around theouter end portion 22 offlexible tube 10 and extends around the closedend 18 of the tube, suchinflatable member 12 being circumferentially sealed or adhered at itsinner edge 24 to the outer wall of theflexible tube 10 by suitable means such as adhesives,

Referring to FIGS. 1 and 2 of the drawing, showing one preferred embodiment of the invention device, and its mode of application,numeral 10 is an elongated flexible tube, preferably formed of rubber, but which can be formed of any suitable flexible plastic material, having two inflatable elastic members orsleeves 12 and 16 surrounding and sealingly attached to thetube 10, such tube being closed at one end as indicated at 18, termed herein the outer end of the tube, and being open at its other end, as indicated at 20, and termed herein the inner end of such tube. Adjacent the inner heat sealing or vulcanization, the remainder of the inflatable member orsleeve 12 remaining unattached so that themember 12 upon inflation forms a bag or balloon surrounding the outer end portion oftube 10, as indicated by thedotted line 26.

The large middle elastic inflatable member orsleeve 16 disposed between theinflatable member 12 and thebulb 14 is circumferentially sealed at its oppositecircumferential edges 28 and 28 as by an adhesive, heat sealing or vulcanization to the outer wall of thetube 10, the remainder ofmember 16 being unattached so that such member upon inflation forms a large central bag or balloon surrounding the middle portion of thetube 10, as indicated by the dotted lines '30. In the embodimerit shown in FIG. 2, it will be noted that the oppositeouter edges 28 and 28 of the middle large inflatable member orsleeve 16 are disposed close to the adjacentperipheralsealed edge 24 ofinflatable member 12, and

theinner side 14 of the'hollowbulb 14.

Theflexible tube 10 has a series ofperipheral apertures 36, e.g. four in number, in the tube wall adjacent theouter end 18 oftube 10, theapertures 36 being equally spaced from each other and being disposed in a plane substantially normal to the axis oftube 10. Theapertures 36 are positioned to provide communication between the interior oftube 10 and the interior of outerinflatable member 12.Tube 10 carries on its outer surface ashort tube 35 which is positioned adjacent the inner side 14' ofbulb 14.Tube 35 is preferably molded on thetube 10, and is provided with apassage 34. Theaperture 34 inshort tube 35 provides communication between the interior of bulb l4 andtube 10, and the interior of the middle largeinflatable member 16.

Disposed within theopen end 20 oftube 10 is ametal sleeve 38, the outer wall of which fits snugly against the inner surface of the wall oftube 10, thesleeve 38 being open at its opposite ends and containing ashoulder 40 which sealingly abuts theedge 42 of thetube 10, adjacent the base of thebulb 14, to position thesleeve 38 properly within thetube 10. Thesleeve 38 is preferably firmly attached to the inner surface of the wall oftube 10, e.g. by a suitable adhesive, although not necessarily if the fit is sufficiently tight to prevent leakage between the outer wall of the sleeve and inner wall oftube 10. Thesleeve 38 passes through the. interior of bulb l4 and has a series ofapertures 44, shown as four in number, and when the sleeve is properly positioned within thetube 10, theapertures 44 in thesleeve 38 communicate via the interior ofbulb 14 with thepassage 34 of thetube 35, to permit fluid communication between the interior ofsleeve 38 and ofinflatable member 16.

Within thesleeve 38 there are provided twoseparate plugs 46 and 48, such plugs being formed of soft rubber having characteristics such that they can be punctured, as by a hypodermic needle of a syringe, but upon removal of such needle, the plugs are resealable.Plug 46 is disposed adjacent the outeropen end 50 of thesleeve 38, and to the left of theapertures 44 therein, and plug 48 is disposed adjacent the inneropen end 52 ofsleeve 38 and spaced fromplug 46, plug 48 being disposed to the right ofapertures 44 insleeve 38.

It is thus seen that plug 46 forms anenclosed space 54 betweenplug 46 and theclosed end 18 oftube 10, and communicating viaapertures 36 with the interior ofinflatable member 12, and spacedplugs 46 and 48 form anenclosed space 56 communicating viaapertures 44 and 34 with the interior of the large inflatableintermediate member 16.

In operation, to control nasal hemmorhage, the nasal tampon of the invention illustrated in FIG. 2 is inserted with theclosed end 18 of tube first, through thenostril 66 and into the nasal cavity or passage 68 of a person, with the outerclosed end 18 of the tube positioned adjacent the inner end of the nasal passage, i.e., adjacent thenasopharynx 70 leading to the throat, the middle portion oftube 10 surrounded by the largeinflatable member 16 disposed entirely within nasal cavity 68, and theouter side 14 of thebulb 14 adjacent theinner end 20 of the tube, being disposed just outsidenostril 66 and anchoring the device in position in the nasal passage. Thehypodermic needle 72 of asyringe 74 is pushed throughplugs 48 and 46 in succession until the end of the hypodermic needle is disposed just to the left ofplug 46 and communicating with theenclosed space 54 in the outer portion oftube 10. The position of the end of the needle throughplug 46 and extending intospace 54 can be ascertained by means of amark 76 at the base ofneedle 72, when such mark is disposed adjacent theinner end 20 oftube 10. The fluid, e.g. air, from the syringe is then injected into the enclosed or sealedportion 54 oftube 10 and viaapertures 36 into theinflatable member 12 to inflate same to the proper extent as illustrated at 26 in FIGS. 1 and 2. In this inflated position as seen in FIG. 1, thebag 26 is disposed under pressure against the adjacent walls of the nasopharynx at the inner end of the nasal cavity, retaining the device in this position and restraining movement thereof outwardly, as indicated byarrow 77 in FIG. 1.

After inflation ofbag 12, which is indicatedto the operator or physician by an increased back pressure in thesyringe 74, theneedle 72 is withdrawn through theforward plug 46, closing the plug and rescaling the enclosedspace 54, thus preventing fluid from escaping frommember 12, and maintainingmember 12 in itsinflated condition 26. When anotherintermediate marking 78 on theneedle 72 is adjacent theinner end 20 oftube 10, this indicates that the end of theneedle 72 is now disposed in the enclosedspace 56 betweenplugs 46 and 48. Fluid from thesyringe 74 is then injected into the enclosedspace 56 and via theapertures 44 insleeve 38 andpassage 34 inshort tube 35, into the large inflatableintermediate member 16, and themember 16 is then inflated until the surfaces thereof are in tight engaging contact with a substantial portion of theinner surfaces 80 and 82 of the nasal passage 68, the resulting inflated bag or balloon now being in the position indicated at 30 in FIGS. 1 and 2. This inflated position ofmember 16 is again signaled by a rise in back pressure in thesyringe 74.

Inposition 30 of the large middleinflatable member 16, as illustrated in FIG. 1, theinflated bag 30 is under sufiicient pressure against thewalls 80 and 82 of the nasal passage to effectively function to prevent or control hemorrhage or bleeding from the major portion of the inner walls of the nasal cavity 68, and to effectively plug the nasal cavity until hemorrhaging is arrested. Upon withdrawing the inner end ofneedle 72 fromplug 48, the plug closes the needle-formed opening therein so thatspace 56 becomes enclosed and sealed and no fluid escapes therefrom or from the balloon l6, and such bag or balloon remains inflated.

The inflated balloons as indicated at 26 and 30, and the bulb l4 effectively maintain and anchor the device in operative position within the nasal cavity 68, as indicated in FIG. 1, until hemorrhaging is effectively controlled or ceases. Theballoons 26 and 30 can then be deflated by first passing the needle throughplugs 48 and 46 intospace 54, and withdrawing the fluid frominflated balloon 26 to deflate same, the needle is then withdrawn fromplug 46 intospace 56, and withdrawing fluid from the large inflatedmiddle balloon 30, followed by complete withdrawal of theneedle 72 throughplug 48. After deflation of theinflated balloons 26 and 30, the device can be pulled from the nasal cavity 68 through thenostril 66.

It will be seen that when theinflated balloons 26 and 30 are deflated, either as result of withdrawal of fluid from such balloons or as a result of possible rupture of such balloons when in their operative position, since the device is anchored by means of thebulb 14 against the nostrils, the device cannot be displaced to the left, as viewed in FIG. 1, and hence cannot be inadvertently aspirated by the patient prior to its being removed in the normal manner through the nostrils, to the right viewing FIG. 1. j

In conjunction with such positive anchoring of the device in the nasal passage by means of thebulb 14, it

- is seen that theinflatable members 12 and 16 can be selectively inflated individually and independently of each other, rapidly and in any desired sequence. This provides a means for readily and quickly controlling nasal hemorrhage and bleeding, particularly in emergencies, and can be operated easily by any technician or physician, without being a specialist in nose and throat medicine.

In the event it is desired to employ the device of FIG. 2 for control of postadenoidectomy bleeding which takes place in thenasopharynx 70, then only theinflatable bag 12 around the closed end of the tube is inflated, without inflatingbag 16. Under these conditions theinflated bag 26 under pressure against the walls of the nasopharynx controls postadenoidectomy bleeding.

The embodiment illustrated in FIG. 3 is similar to that illustrated in FIG. 2, except that in FIG. 3 thesleeve 38 is not employed. In FIG. 3 theplugs 46 and 48 are positioned within theflexible tube 10, theplug 46 being disposed withintube 10 adjacent the outer side 14' ofbulb 14, and theplug 48 being disposed within the inner end portion oftube 10 adjacent the oppositeinner side 14" of bulb l4, andportion 10 oftube 10 having a larger diameter than themain body portion 10" oftube 10, to facilitate use of larger diameter plugs for easy manipulation of a syringe needle for inflation with the syringe. It will also be noted in the embodiment of FIG. 3 that a series of peripheral apertures 34', shown as four in number, are disposed in the wall of tube 10 a short distance beyond theouter sides 14 of theplug 14, and positioned in a plane substantially normal to the axis oftube 10, providing communication of the enclosedspace 56 betweenplugs 46 and 48, and the intermediate inflatable member orbag 16.

FIG. 4 shows the specific arrangement of FIG. 3, butincluding ametal sleeve 38, containing theplugs 46 and 48 positioned in opposite ends thereof, the apertures 44' of the metal insert orsleeve 38 being disposed farther forward than in the case of theapertures 44 ofsleeve 38 in FIG. 2, the apertures 44' ofsleeve 38 communicating with theapertures 34 oftube 10.

- In this modification, sleeve 38' carries aflange 83 which rests against theinner edge 85 oftube 10 to position the sleeve properly intube 10.

Although the embodiments of FIGS. 2 and 4 involve the use of an additional member, namely, the insert orsleeve 38 or 38, such sleeve is readily manufactured and theplugs 46 and 48 can be easily positioned therein and the resulting assembly then readily inserted into the inner end oftube 10. In the modification of FIG. 4, the sleeve and plug assembly is rotated to the proper registering position of theapertures 44 with the correspondingapertures 34 in the tube wall, as described above, by employing registering markings such as illustrated at A and .B at the inner ends of the tube and sleeve, respectively, as indicated in FIG. 4. The use of a metal sleeve such as 38 or 38' as shown in FIGS. 2 and 4 has the important advantage that it prevents accidental puncture of thetube 10 by the hypodermic needle of the syringe, if the needle is not introduced axially through theplugs 48 and 46, and is accidentally directed askew of the center oftube 10.

It will be understood that the concept of the present invention can be employed using only a single inflatable member such as 12 sealingly disposed around the closed outer end of the tube, without employing any intermediate inflatable member such as shown at 16 in FIG. 2. Thus, in the embodiment illustrated generally in FIG. 6, only the outerinflatable member 12 at the outer end oftube 10 is employed. This can be accomplished in the first place by omitting apertures 34', provided in the wall oftube 10 as illustrated in FIG. 3, and asingle rubber plug 48 which is self sealing, as in the case ofplug 48 of FIG. 3 is inserted into theopen end portion 10 oftube 10. Note also in the embodiment of FIG. 6 that the additional plug, as indicated at 46 in FIG. 3 is omitted. The single inflatable balloon device of this modification can be inserted into the nasal cavity for control of postadenoidectomy bleeding, or can be used in certain instances to control nasal bleeding and wherein it may also be desirable to pack at least a portion of the nasal cavity with gauze for most effective control of bleeding.

The modification illustrated in FIG. 7 is similar to that of FIG. 6, except thatplug 48 can be inserted into thetube 10 to the left ofbulb 14 as viewed in FIG. 7,

the inner end portion 10' to the right ofbulb 14 in FIG.

. 7 being shorter thanend portion 10 oftube 10 in FIG.

The embodiment of FIG. 6 is preferred over that of FIG. 7, since one can more readily and quickly insert the needle of the syringe into the plug 48' at the extreme inner end oftube 10 in FIG. 6, whereas in FIG. 7, the needle of the syringe must be passed throughtube 10 beyond thebulb 14 for insertion inplug 48.

Now referring to FIG. 8, it will be seen that the above-described devices of the invention, such as illustrated in FIGS. 2 and 6, can be modified so that thebulb 14 is not integrally molded or formed on the tube .10, but rather thetube 10 can be provided at its inner open end with aflange 90 of reduced wall thickness, and a separate assembly provided, comprising thebulb 14 andinner end portion 10, and having an outer I flange 92, theflanges 90 and 92 being secured together, as by means of a suitable adhesive, to assemble the tube and bulb portions.

In still another embodiment (not shown), in place of employing only a single inflatableintermediate bag 16, as seen in FIGS. 2 and 3, there can be employed a pair of such intermediate inflatable members. This can be accomplished, e.g. by modification of the embodiment of FIG. 2 to lengthensleeve 38 and to provide an additional soft rubber plug insleeve 38, spaced from and to the left ofplug 46, in FIG. 2, with an additional set of registering apertures in thewall 10 of the tube and thesleeve 38, between said additional plug and plug 46, so as to permit independent inflation of the above-noted pair of intermediate inflatable members.

Water may be used to inflate the inflatable members, e.g. 12 and 16, since an exact amount of water can be easily measured and the volume displacement of the respective inflatable bags predetermined. Also, water does not permeate rubber walls as do many gases and the inflation of the bags remains relatively permanent until the water is drained from the inflatable balloons. However, air may be preferable since in the event of a balloon rupture, there would be no danger of aspirating water. I Y

The seals or plugs, e.g. 46 and 48, can be formed of any suitable soft rubber or plastic, which can be readily punctured by a syringe needle and are resealable upon removal of the needle. Thus, such plugs can be formed of materials of the above type which can be punctured by either a sharp or a blunt syringe needle.

Referringnow to FIGS. 9 to 15, the device is provided with aflexible tubular member 94 having aninflatable balloon 96 secured thereabout and sealed at itsends 98 to thetubular member 94. One ormore openings 100 provide communication between the interior of thetubular member 94 and the interior of theballoon 96. The parts of this device are shaped and proportioned so that theinflatable balloon 96 stops nose bleeds by compressing the main artery to the interior of the nose (the sphenopalatine artery) as it enters the nasal cavity before it forms any branches. This feature is superior to that of other balloons which are designed to compress a branch of the artery at the point where the bleeding occurs. The reason that such other balloons are not as effective as the device of the present invention is because very often the bleeding branch lies in an area covered by an overhanding structure and therefore is not contacted by the balloon.

As best shown in FIGS. 11 and 12, thetubular member 94 near its open end is' enlarged in diameter to form a self-sustainingbulbous formation 102. Thebulbous formation 102 has walls of substantially the same thickness as theflexible tube 94, which is sufficient for the bulbous formation orbulb 102 to be self-sustaining even in the absence of any internal pressure. As shown, thebulb 102 defines an annular inwardly facing chamber in communication with the interior of thetube 94. Thebulb 102 not only serves as a safety feature to prevent the device from slipping into the patients throat and obstructing the airway, but it also holds the balloon in the proper position within the nose so that when theballoon 96 is inflated the wall thereof presses directly on the sphenopalatine artery and compresses it against the bone behind it.

Avalve structure 104 is provided with atubular body portion 106 extending into theopen end portion 108 oftube 94 and aflange 110 thereon limits inward movement of the valve structure. An outertubular portion 112 extends outwardly from thebody portion 106. Thetubular portion 112 is provided with acentral bore 114 and thebody portion 106 has anenlarged bore 116 therein. The region between the boxes 1 14 and 1 16 defines avalve seat 118. Thebore 116 is provided with internal flutes orgrooves 120, as best shown in FIG. 14. A solid body of rubber-like material 122 has an enlarged cylindrical portion occupying thebore 116 and a smallercylindrical projection 124 extending outwardly intobore 114. Ashoulder 126 on thebody 122 normally seats againstvalve seat 118, it is maintained seated thereagainst by inwardly turnedportions 128 at the inner end oftubular body portion 106 and is preferably maintained under very slight compression to provide a seal against theseat 118. Thecylindrical portion 122 is provided withlongitudinal ribs 130 and those ribs coupled with thechannels 120 providelongitudinal passageways 132 for air around thebody 122. As shown, the reducedcylindrical portion 124 is provided with a transverse groove or slot 134 at its outer end.

A suitable source of air under pressure, such as the syringe generally designated 136, is provided with atubular nipple 138 of a size to be received within thebore 114 and of a length sufficient to engage the outer end ofcylindrical extension 124 and to push the same inwardly to compress thevalve body 122 and thus move theshoulder 126 away fromvalve seat 118. Thetransverse groove 134 ensures a passageway for air from the interior ofnipple 138, around thecylindrical extension 124,past valve seat 118 and alongpassageways 132 to the interior oftube 94 for inflation ofballoon 96. FIG. 12 shows the parts in their relative positions when theballoon 96 is being inflated. After theballoon 96 is sufficiently inflated, thenipple 138 is merely withdrawn fromtubular extension 112 whereupon thebody 122 resiliently expands to reseat itsshoulder 126 againstvalve seat 118 and thereby retain theballoon 96 in inflated condition. Obviously, theballoon 96 may be deflated at will by merely reinserting thenipple 138 to the position of FIG. 12 and permitting the air to escape or actually withdrawing it by operation of thesyringe 136.

It will be apparent from the foregoing description and the drawings herewith that thebulb 14 or 102, which has been referred to as semi-rigid has sufficient rigidity to be self-sustaining even in the absence of internal pressure. This fact is clear from the description and is also clearly exhibited by the form shown in FlG. 7 wherein the interior of thebulb 14 is never pressurized.

The term nasal tampon as employed in the specification and claims is intended to include use of the device also as a nasopharyngal tampon, as described above.

While I have described particular embodiments of my invention for the purpose of illustration, it should be understood that various other modifications and adaptations thereof may be made within the spirit of the invention, and hence the invention is not to be taken as limited except by the scope of the appended claims.
