for the purposes of promoting an understanding of the principles of the invention , reference will now be made to the embodiment illustrated in the drawings and specific language will be used to describe the same . it will nevertheless be understood that no limitation of the scope of the invention is thereby intended , such alterations and further modifications in the illustrated device , and such further applications of the principles of the invention as illustrated therein being contemplated as would normally occur to one skilled in the art to which the invention relates . referring to fig1 there is illustrated an enema tip retention apparatus 20 including clamp member 21 , adjustable belt arrangement 22 , enema tube 23 and enema tip 24 . clamp member 21 includes a mounting plate portion 27 adjustable , releasable clamp 28 and collar buttons 29 and 30 which provide retaining means for securing clamp member 21 to adjustable belt arrangement 22 . belt arrangement 22 includes a first strap portion 31 which is variable in circumferential encompassing size by means of belt buckle 32 and adjustment holes 33 . looped around first strap portion 31 are retaining straps 36 and 37 whose length extension from first strap portions 31 in a downwardly direction is controlled by adjustment means 38 and 39 . adjustment means 38 and 39 ( see fig7 ) include a collar stickpin - type arrangement wherein the outermost enlarged end portions of pin 40 are inserted through strap holes and thereby disposed on opposite outwardly facing surfaces of their corresponding retaining straps . this arrangement securely forms an enclosing loop for each strap which surrounds first strap portion 31 . the free ends of retaining straps 36 and 37 each include a keyhole - shaped slot 41 and 42 , respectively , which are suitably sized and arranged for engagement with and receipt of collar buttons 29 and 30 . collar buttons 29 and 30 ( see fig1 a and 2 ) each include a base portion 45 , an enlarged head portion 46 and a reduced diameter portion 47 therebetween . the size and shape of collar buttons 29 and 30 is such that enlarged head portion 46 is able to pass through larger opening 48 of keyhole - shaped slots 41 and 42 but not the smaller oblong opening portion 49 . thus , the means of attachment of clamp member 21 to adjustable belt arrangement 22 is to insert collar buttons 29 and 30 into keyhole - shaped slots 41 and 42 and then pull outwardly on retaining straps 36 and 37 such that reduced diameter portions 47 are snugly anchored within smaller oblong openings 49 , and retained there due to the larger sizes of head portion 46 and base portion 45 . referring to fig2 clamp member 21 is illustrated in greater detail and includes a deformable tab portion 52 , a cooperating locking portion 53 , which has a series of ratchet teeth 54 , and a clearance aperture 55 located adjacent the common end of portions 52 and 53 . clearance aperture 55 extends through clamp member 21 , including mounting plate portion 27 . enema tube 23 is partially shown in both fig1 a and fig2 illustrations and is disposed within clearance aperture 55 . as deformable tab portion 52 and cooperating locking portion 53 are drawn together , by squeezing , the dimensional size of clearance aperture 55 is reduced , and a clamping action occurs around enema tube 23 thereby holding this tube in position . inasmuch as the longitudinal axis of clearance aperture 55 is substantially perpendicular to mounting plate portion 27 , it should be apparent that when clamp member 21 is oriented near the rectal opening of a patient and first strap portion is secured around the patient &# 39 ; s waist , that retaining straps 36 and 37 may be adjusted in length until clamp member 21 is drawn snugly up against the patient &# 39 ; s rectal opening so that the enema tube 23 and its joined enema tip 24 are retained in position within the patient . by securing the enema tube and tip in such a manner , the enema tip is unable to slip out of the patient as the patient turns from one side to the other and orients his body in various positions which the radiologist or physician may request as part of the fluoroscopy x - ray examination procedure . referring to fig3 and 5 , alternative arrangements of clamp member 21 are illustrated . while it should be understood that the preferred arrangement of clamp member 21 with respect to the remainder of apparatus 20 is to have the smooth surface of mounting plate portion 27 closest to the patient , it is possible to use an orientation wherein the collar button side of mounting plate portion 27 is closest to the patient . it is also possible to arrange adjustable , releasable clamp 28 such that the longitudinal axis of its clearance aperture is parallel with the surface of mounting plate portion 27 rather than being perpendicular to it . fig3 illustrates such an arrangement where clamp 28 is disposed on mounting plate portion 27 so that the longitudinal axis of clearance aperture 55 is substantially parallel with the surface of mounting plate portion 27 . also included is a tube 56 which is shown in section only and secured by clamp 28 . this tube may be a drainage tube or similar device and thus , the arrangement of fig3 is suitable for retaining such tubes in a fixed position so that drainage of the patient cavities can be achieved , such as the sinuses . while this particular arrangement may not be best suited for enema administering , the clamping concept is virtually the same as clamp member 21 and collar buttons 29 and 30 are provided for retention of this alternative clamp member when such drainage of cavities is desired to be achieved . referring to fig4 there is illustrated a clamp , enema tube and enema tip combination 59 which is a one - piece , integral , molded assembly . combination 59 includes an enema tube 60 , an enema tip 61 , a mounting plate 62 , a clearance hole grommet 63 , collar button 64 and collar button 65 . although fabricated as a molded , one - piece combination , it is possible that these various component parts could be individually molded and then fitted together in a press - fit manner such that grommet 63 would be anchored within mounting plate 62 and would provide a snug fit around the outside diameter of enema tube 60 such that the tube and tip 61 would be held securely in position within the patient . in this manner , collar buttons 64 and 65 would be utilized as has been previously explained for collar buttons 29 and 30 of fig1 . referring to fig5 the alternative clamp member of fig3 is illustrated and includes a tubular insert 69 which has a lateral cross section of a &# 34 ; c &# 34 ; shape . this insert is generally concentric with clearance aperture 55 and is suitable to adapt the inside diameter size of clearance aperture 55 to the outside diameter of tube 70 such that various - sized tubes can be held by the clamp member . all that is required for adaptation is to select the appropriately sized c - shaped insert with the desired thickness . the use of such inserts is also envisioned with clamp member 21 inasmuch as the orientation of the clamp 28 with respect to the mounting plate portion 27 , whether parallel or perpendicular , is equally well suited for the addition of such inserts . referring to fig6 an alternative arrangement of the fig1 apparatus is illustrated and although belt arrangement 71 is similar to belt arrangement 22 , the noted difference involves the design of retaining straps 72 and 73 which are joined together at the general location of the enema tube 74 and enema tip 75 by means of retaining portion 76 . retaining portion 76 serves virtually the same purpose as did the free ends of retaining straps 36 and 37 which were provided with keyhole - shaped slots 41 and 42 , respectively . in the fig6 illustration , keyhole - shaped slots 77 and 78 ( see fig8 ) are provided and the only difference between the retaining portion arrangement of fig1 and that of fig6 is that the two retaining straps 72 and 73 are joined together wherein their y - shaped configuration and union at two locations creates a clearance opening 79 . enema tube 74 and enema tip 75 are joined together and extend through a retaining flange 82 which includes two oppositely disposed collar buttons 83 and 84 which are suitably positioned and sized to fit within keyhole - shaped slots 77 and 78 . in order to insert retaining flange 82 into retaining portion 76 , the outer ends of flange 82 must be drawn together by bending flange 82 and then insert collar buttons 83 and 84 into the enlarged opening portions of slots 77 and 78 . by fabricating retaining flange 82 out of a resilient , flexible material , release from this bent position will cause the collar buttons to flip outwardly thereby locking them in position in the smaller oblong opening portions of slots 77 and 78 . this locking engagement securely retains the enema tube and enema tip as part of belt arrangement 71 . the free end of enema tube 74 is provided with a series of angularly arranged layers or serrations 85 and these provide a snug fit arrangement with flexible tube 86 which may be forced over the free end of enema tube 74 . tube 86 may then be connected to a source of barium for introduction into the patient . referring to fig9 an alternative arrangement to the retaining portion designs of fig1 and 6 is illustrated . retaining flange 89 is a separate component and includes keyhole - shaped slots 90 and 91 and a clearance opening 92 . retaining straps 93 and 94 are provided with collar buttons 95 and 96 , respectively , disposed at their free ends . as has been previously described , collar buttons 95 and 96 are arranged to be received by slots 90 and 91 for fixed retention of retaining flange 89 . the clearance opening 92 of retaining flange 89 is suitably sized to receive in a snugly - fit arrangement an enema tip and tube combination or similar tubular member . referring to fig1 and 11 , still further alternative arrangements are illustrated . in fig1 , mounting plate 99 is provided with a serrated tubular member 100 secured therethrough as well as collar buttons 101 and 102 . serrated tubular member 100 extends beyond each surface of mounting plate 99 a distance sufficient for the connection of enema tip 103 and enema tube 104 . by fabricating the enema tip and enema tube members out of a flexible resilient material , they may be easily axially forced over the extending portions of serrated tubular member 100 and firmly lock onto the serrated surfaces , thereby providing a fixed and integrally appearing arrangement . in fig1 , the enema tip 107 is secured to mounting plate 108 and has a free end 109 of a serrated tube design . in this arrangement , enema tube 110 will fit over the extending serrations of free end 109 and although the enema tip and mounting plate are an integral design , various enema tubes may be used in this particular combination . although a conventional enema tip and enema tube combination have been illustrated throughout this specification , it is to be understood that the retaining and clamping arrangements disclosed herein are equally suitable for use with various types and styles of enema tips and tubes , including , but not limited to , those disclosed in my copending patent application , ser . no . 39 , 502 , filed on may 16 , 1979 now abandoned . thus the arrangements disclosed herein are suitable for double - contrast studies in which air is introduced after the barium is evacuated . in fact , the arrangements disclosed in the specification are particularly well suited to such double - contrast studies in that the enema tube and tip can be retained within the patient throughout the study in a well - secured and comfortable manner and is not subject to slipping out or otherwise separating from its inserted position within the patient . thus , in combination with any of one the various barium and air combination tubes of my copending patent application , barium is first introduced and then evacuated and then air is subsequently introduced into the patient and all of these operations may be performed without the necessity to remove the enema tip from the patient . while the invention has been illustrated and described in detail in the drawings and foregoing description , the same is to be considered as illustrative and not restrictive in character , it being understood that only the preferred embodiment has been shown and described and that all changes and modifications that come within the spirit of the invention are desired to be protected .
an enema tip retention apparatus for retaining an inserted enema tip in a patient during the administering of an enema to the patient includes an adjustable belt for encompassing the waist of the patient and including depending straps which couple to a substantially flat mounting plate . the mounting plate has a clamp disposed thereon and a clearance aperture therethrough and includes two collar buttons which are arranged for connection to the two depending straps . the clamp has a ratcheted arrangement such that its clearance aperture diameter may be varied , depending upon the enema tube outside diameter which is inserted therethrough . with the depending straps coupled to the collar buttons , the mounting plate may be drawn adjacent the rectal opening of the patient and with the enema tip and tube anchored by the clamp , this tip and tube may be held in position throughout a fluoroscopy examination and will be retained in its desired position , regardless of the movements and the maneuvers the patient is subjected to .
