s index and middle fingers are cupped beneath the finger grip portion 18 and the user &# 39 ; s thumb is placed on the exterior surface 19 of the finger grip portion 18 and obturator 54 while locked by one or more teeth members 29 and 31 . if optional stabilizing lifts 42 and 44 are not present as illustrated in fig1 , the external retention skin disc 56 is placed between the arm lifts 38 and 40 and finger grip portion 18 such that the arm lifts 38 and 40 underlyingly support the skin disk 56 . the tube 50 is fed into the peritoneal cavity and into an organ 59 such as the stomach through a stoma 52 . the external retention skin disc 56 is placed on the stoma 52 so as to be at skin level and is maintained at this level by applying appropriate force on the gastrointestinal insertion or removal device 10 of the present invention . an obturator device 54 is then used to enlarge the slenderized internal retention bolster 58 to thus hold tube 50 in position . such enlargement of the slenderized retention bolster is achieved by releasing the obturator device 54 from beneath teeth members 29 and 31 with one &# 39 ; s thumb thus releasing the pressure thereon . by releasing the pressure , obturator device 54 extends upwardly from enlarged bolster 58 through groove 30 . groove 30 of device 10 allows the necessary space for manipulating and utilizing the obturator device 54 . once the internal retention bolster 58 has been enlarged , the external retention skin disc 56 is removed from between the stabilizing lifts 42 and 44 if present and arm lifts 38 and 40 by sliding and / or tilting the device away therefrom . a gastrointestinal - type tube is removed using the present device by reversing the above procedure . namely , as illustrated in fig1 , device 10 is slid and / or tilted so as to locate the external retention skin disc 56 between stabilizing lifts 42 and 44 and arm lifts 38 and 40 . stabilizing lifts 42 and 44 are optional for this procedure . the obturator device 54 is then used to slenderize the internal retention bolster 58 . slenderization is achieved by applying downward pressure toward said stoma on the obturator device 54 with one &# 39 ; s thumb to slide the obturator device 54 through groove 30 . the obturator device is then locked in this position by means of teeth members 29 and 31 wherein the obturator 54 forces the bolster 58 into an elongated form having a diameter similar to that of the tube . two teeth members 29 and 31 are preferred although one or more could be utilized . device 10 is then pulled in a direction away from stoma 52 by having the index and middle fingers cupped beneath the grip portion 18 thus extracting the external retention skin disc 56 , attached tube 50 and bolster 58 from the stoma and peritoneal cavity . the gastrointestinal tube insertion or removal device of the present invention may be made of one or more suitable materials selected from but not limited to the group consisting of metal , synthetic monomers , synthetic polymers , synthetic copolymers and synthetic polymer blends . preferably the device is integrally formed from metal . if the device is not integrally formed as preferred , the various features of the device may be attached or secured through any suitable means such as but not limited to one or more welds , friction fit , one or more adhesives , male and female threaded means , male and female interlocking means or any combination thereof . the gastrointestinal tube insertion or removal device of the present invention may be manufactured according to any suitable dimensions but preferably the arm lifts are spaced apart by approximately one half inch to approximately one inch . the optional stabilizing lifts should preferably be spaced apart from the aim lifts by approximately one sixteenth of an inch to one inch . if the optional stabilizing lifts are not present , the finger grip portion may be spaced apart from the arm lifts by approximately one sixteenth of an inch to one inch as illustrated in fig1 . it is seen therefore that the present invention provides an effective gastrointestinal tube insertion or removal device which has specific advantages over the heretofore known means of insertion and removal of gastrointestinal tubes . the device eliminates risks associated with the internal retention bolster being expanded intra - peritoneal before fully inserted in the desired location , allows for reliable positioning of the gastrointestinal - type tube , allows for re - slenderization of the internal retention bolster before removal , provides more comfort for the patient by eliminating the need to apply abdominal pressure for placement and prevents enlargement of the stoma and problems related thereto . hence , for these reasons as well as others some of which hereinabove set forth , it is seen that the invention represents a significant advancement which has substantial medical and commercial significance . while there is shown and described herein certain specific embodiments of the invention , it will be manifest to those skilled in the art that various modifications may be made without departing from the spirit and scope of the underlying inventive concept and that the same is not limited to the particular forms herein shown and described except insofar as indicated by the scope of the appended claims .
