referring particularly to the drawings , there is shown the huber needle safety enclosure 10 of this invention . the safety enclosure 10 includes , generally , a needle housing 12 and a panel unit 14 . the needle housing 12 includes an elongated cylindrical hinge tube 16 which is constructed of plastic as well as almost all of the components of this enclosure 10 . the only part that is not constructed of plastic will be the huber needle 18 itself , which will be constructed of metal . the huber needle 18 is in the shape of a right angle and has a fore end 20 and an aft end 22 . the fore end 20 is connected to the aft end 22 at a bend 24 . the free end of the fore end 20 is formed into a sharpened tip 26 . the hinge tube 16 has a through passage 28 . the aft end 22 of the huber needle 18 is located in a close fitting but yet slidable manner within the through passage 28 . integrally connected to the hinge tube 16 at its front end is a sleeve 30 . longitudinally formed within the sleeve 30 is a slot 32 . the wall surface of the slot 32 includes a pair of ridges 34 and 36 . the ridges 34 and 36 are located in lateral alignment with each other . however , this is not mandatory as they could be slightly spaced apart . the fore end 20 of the huber needle 18 is press fitted within the slot 32 with the ridges 34 and 36 forming a tight or an interference fit that tends to hold the huber needle 18 in conjunction with the slot 32 . this holding of the huber needle 18 in position with the slot 32 is generally during assembly of the safety enclosure 10 and will tend to prevent accidental dislodgement of the huber needle 18 from the slot 32 . the reason for this is that the safety enclosure 10 is manufactured at a plurality of different stations at an assembly line . one of the first steps in the assembly line is to insert the huber needle 18 in conjunction with the needle housing 12 and then that resultingly assembled unit is then moved to the next station . the reason for the ridges 34 and 36 is to prevent the needle 18 from accidentally disengaging from the needle housing 12 during movement from one station to another . the outer end of the sleeve 30 is formed into an outwardly flared collar 38 . the function of this collar 38 will be explained further on in the specification . the needle housing 12 includes an enlarged finger pad 40 which has a flat top 42 . the flat top 42 is to facilitate the application of finger pressure by the installer of the enclosure 10 of this invention . applying finger pressure onto flat top 42 will cause the sharpened tip 26 and the fore end 20 to penetrate a septum of an implanted port , which is not shown . however , the implanted port would be included within the human body 44 , which is depicted generally in fig2 . the enlarged finger pad 40 is formed integral to the sleeve 30 and also to the hinge tube 16 . formed diametrically opposite the exterior surface of the sleeve 30 are a pair of elongated ridges 46 . the function of these ridges will also be explained further on in the specification . the huber needle 18 has a through conduit 48 . this conduit 48 connects to a through passage 50 formed within an extension tube 52 . generally , the extension tube 52 will be made of plastic . the extension tube 52 is placed coaxially with bore 54 of the hinge tube 16 . bore 54 is of a slightly greater diameter than the through passage 28 . it is to be understood that fluids , which includes drugs , solutions , hydrating liquids , etc ., are to be supplied through the through passage 50 to within the through conduit 48 to be dispensed exteriorly of the sharpened tip 26 . it is also considered to be within the scope of this invention that fluid could be withdrawn from the through conduit 48 and the through passage 50 for the purpose of performing medical tests or for other medical reasons . in order to insure that the extension tube 52 remains in position , there will be an adhesive 56 that will be applied which will adhesively secure the extension tube 52 to the aft end 22 of the huber needle 18 . any desirable medically approved adhesive will be satisfactory . the panel unit 14 is constructed of an end panel 58 , an intermediate panel 60 , another intermediate panel 62 and another end panel 64 . all of the panels 58 , 60 , 62 and 64 are generally constructed planar sheet material with plastic being preferred . panel 58 is connected to panel 60 by living hinge sections 66 and 68 . formed within the end panel 58 is a cutout area 70 . integrally mounted on the edge of the panel 60 is an elongated protuberance 72 . the elongated protuberance 72 passes within the cutout area 70 as end panel 58 pivots relative to intermediate panel 60 about living hinges 66 and 68 . the free outer edge of the end panel 58 is formed into flat extension 74 . integrally connected to the lower surface of flat extension 74 is a tube 76 . tube 76 has a through passage 78 . formed through the surface of the intermediate panel 60 are a series of ventilation holes 80 . also , fixedly mounted on the inside surface of the intermediate panel 60 is a post 82 . the upper end of the post 82 is formed into a lateral extension , which is defined as a hook 84 . alongside of the post 82 and formed within the panel 60 is an elongated hole 86 . there are shown four in number of the ventilation holes 80 formed within the intermediate panel 60 . however , it is considered to be within the scope of this invention that the number of ventilation holes 80 could be increased or decreased without departing from the scope of this invention . the intermediate panel 60 is connected by a living hinge 88 to intermediate panel 62 . it is to be understood that a living hinge is a term that is commonly used to define a thin or narrowed piece of plastic that connects between two thicker pieces of plastic with that thin piece of plastic allowing pivoting movement between the pieces of plastic . the intermediate panel 62 also includes a plurality of ventilation holes 90 with four in number being shown with it again being understood that this number could be increased or decreased without departing from the scope of this invention . also mounted on the inside surface of the intermediate panel 62 is a post 92 . the upper end of the post 92 terminates in a laterally extending member defined as a hook 94 . mounted directly adjacent the post 90 is elongated hole 96 . the elongated hole 96 extends entirely through the intermediate panel 62 . the intermediate panel 62 is connected by living hinges 98 and 100 to end panel 64 . in between the living hinges 98 and 100 there is located an elongated protuberance 102 which is fixedly mounted on the intermediate panel 62 . the elongated protuberance 102 is positioned within cutout area 104 which is formed within the end panel 64 . the free side edge of the end panel 64 is formed into a flat extension 106 . fixedly mounted to the underside of the flat extension 106 is a tube 108 . formed through the tube 108 is a through passage 110 . the diameter of the through passage 110 equals the diameter of the through passage 78 . fixedly attached to the flat extension 106 and also to tube 108 is a gripping handle 112 . the bore 54 is formed through the gripping handle 112 . gripping handle 112 has a lower extension 116 . the sidewalls of the gripping handle 112 include a series of elongated grooves 118 . the manufacturing procedure for the safety enclosure 10 of this invention is as follows : the aft end of the huber needle 18 is inserted within the through passage 28 of the hinge tube 16 . the fore end 20 is moved until it fully engages with slot 32 with the ridges 34 and 36 creating a binding action against the fore end 20 . the panel unit 14 is positioned so tube 76 abuts tube 108 and through passages 78 and 110 align . at this time , the enlarged collar is then forced through the passages 78 and 110 . it is to be noted that the enlarged collar 120 has a beveled forward surface and a vertical rear wall 122 . the hinge tube 16 is moved sufficiently through the passages 78 and 110 until the rear wall 122 and collar 120 are located within the bore 54 . at this time , withdrawal of the hinge tube 16 is prevented by the rear wall 122 which is not capable of being conducted over annular wall 124 of the tube 108 . formed between the intermediate panels 60 and 62 is a notch 126 . the panels 60 and 62 are moved to the position shown in fig2 until outwardly flared collar 38 engages with the notch 126 . this , in essence , provides a slight lock to hold the panel unit 14 in the position shown in fig2 so end panel 58 forms a relatively sharp acute angle relative to intermediate panel 60 . at this particular time , the hook 84 abuts against the inside surface of the end panel 58 . at the same time , the end panel 64 forms an acute angle with intermediate panel 62 with hook 94 to abut against the inside surface of end panel 64 . in order to protect the assembler by being stuck by the sharpened end 26 of the huber needle 18 , there is placed over the fore end 20 a protective tube 128 . the now assembled safety enclosure 10 is to be placed within a shipping container , irradiated or gassed in order to sterilize the enclosure 10 , and then transport such to the consumer . the consumer removes the safety enclosure 10 from its package , which will generally occur in close proximity to the human body 44 . a medical practitioner will then remove the protective tube 128 from the huber needle 18 . the medical practitioner would grab the gripping handle 112 between thumb and middle finger and orient the safety enclosure 10 in the proper position for insertion . that position would be with the sharpened end 26 directly against the septum of the implant port , which is not shown , which is mounted within the human body 44 . the medical practitioner then places his or her index or first finger on flat top 42 or against flat extension 74 and 106 . the medical practitioner then applies a downward pressure sufficient to cause the sharpened end 26 to penetrate the implant port . the implant port will be covered with a flexible rubber layer which is to be penetrated by the fore end 20 of the huber needle 18 . once the fore end 20 is inserted to the proper depth within the implant port , the exterior surface of the intermediate panels 60 and 62 is to be located against the human body 44 . in order to aid comfort to the patient , not only is there provided the ventilation holes 80 and 90 but there is also provided a flattened area 130 on the exterior surface of intermediate panel 62 . there is a similar flattened area , which is not shown , on the exterior surface of the intermediate panel 60 . these flattened areas , when against the body of the patient , provide a more comfortable surface than if the surfaces were not flat . one advantage of the structure of the safety enclosure of the present invention is that when it is installed in conjunction with the human body 44 that the lower extension 116 of the gripping handle 112 actually rests on the body of the human 44 . this resting of the lower extension 116 essentially prevents any rocking movement of the safety enclosure 10 relative to the implant port . rocking motion can occur during normal daily activity , which includes sleeping of the patient . this rocking motion over a period of time can actually cause the huber needle 18 to be withdrawn from the implant port . the locking action produced by outwardly flared collar being engaged with the notch 126 can be overcome by the application of a small amount of force in the form of a squeezing action that is applied to the elongated protuberances 72 and 102 . these protuberances 72 and 102 , because of their shape relative to the side edges of the end panels 58 and 64 and intermediate panels 60 and 62 , provides a smoothly contoured structure that readily indicates to the user that the hand is in the proper position for applying the squeezing force . it is to be remembered that the overall structure of the present invention is quite small with the distance between the protuberances 72 and 102 , in the position shown in fig2 , being approximately one and one - quarter inches . because the medical practitioner installer is working with such a small unit , the using of the smoothly contoured protuberances 72 and 102 grant to the medical practitioner a certain feel that tells that medical practitioner that the hand is in the proper position for applying the squeezing force . let it be assumed that it is now desired for the medical practitioner to remove the safety enclosure 10 of this invention from the implant port . the safety enclosure 10 , shown in fig2 , will actually be taped with adhesive tape , which is not shown , to the human body 44 . a dressing would then be applied . this tape is removed . the medical practitioner places a thumb on elongated protuberance 102 and an index finger on elongated protuberance 72 and applies a squeezing force . only a small amount of force is required that will cause the end panels 58 and 64 to move upwardly disengaging the collar 38 from the notch 126 . further squeezing force results in the end panel 58 to be moved alongside of end panel 64 . at the same time , intermediate panel 60 is moved directly alongside of intermediate panel 62 . in this position , the hook 84 is conducted through the elongated hole 96 with the undersurface of the hook 84 abutting against the exterior surface of the intermediate panel 62 . at the same time , the hook 94 is conducted through the elongated hole 86 with the undersurface of the hook 94 being located against the exterior surface of the intermediate panel 60 . the result is that the safety enclosure 10 is in the position shown in fig6 and is locked in that position by the hooks 84 and 94 . the sharpened end 26 of the huber needle 18 is clamped between the intermediate panels 60 and 62 making it impossible for the medical practitioner to experience any needlestick injury . at this particular time , the safety enclosure 10 is then discarded at an appropriate discarding location . the including of the grooves 118 on the gripping handle 112 is to provide a roughened surface to facilitate gripping of the gripping handle 112 . also , it is to be noted that the exterior sidewalls of the gripping handle 112 are formed slightly concave , which again are for the purpose of ergonomics to make it more comfortable when using of the gripping handle 112 . the flattened areas , such as flattened area 130 , permit the application of a cushioning pad , if such is desired . this cushioning pad would be positioned between the safety enclosure and the skin of the patient . the structure of this invention can be incorporated within different sizes of huber needles 18 . the hinge tube 16 could be manufactured in different colors with a particular color to be coordinated with a particular size of huber needle 18 . also , the panel unit 14 could be manufactured of a transparent plastic material to allow visibility of the access site of the huber needle 18 within the implant port by the medical practitioner . typically , the length and gauge of the fore end 20 of the huber needle 18 might possibly be printed on the exterior surface of the end panels 58 and 64 as there will probably be utilized different lengths for the fore end 20 of the huber needle 18 .
