DESCRIPTION

Construction

[0064] Referring to FIGS. 1 and 2, the invention is a packaged catheter 10 equipped with a dispensing device 30.

[0065] Packaged Catheter

[0066] The packaged catheter 10 includes a catheter 60, such as an intermittent urinary catheter, retained within the product retention chamber 29 of a package 20. The catheter 60 defines an insertion end 61 and a fixture end 62, and a longitudinal central axis 69.sub.CA.

[0067] Catheter

[0068] The catheter 60 may have any desired longitudinal length and shape effective for achieving the function of eliminating urine from the bladder of a male or female patient. Preferably, the longitudinal length for an adult female catheter 60 is between 2-6 inches, the longitudinal length of the adult male catheter 60 is between 10-16 inches, and the longitudinal length of a pediatric catheter 60 is between 5-11 inches.

[0069] Packaging

[0070] The packaging 20 may be selected from any of the customary packaging used for cathaters so long as the packaging is sufficiently supple and flexible that the packaging 20 does not prevent or inhibit translation of the movement control devices (31 and 32) towards and away from one another when gripped through the packaging 20.

[0071] Dispensing Device

[0072] The dispensing device 30 includes a pair of movement control devices (31 and 32) for facilitating longitudinal x movement of the catheter 60 from a second longitudinal end 22 of the packaging 20 towards a first longitudinal end 21 of the packaging 20 for controlled dispensing of the catheter 60 from the packaging 20.

[0073] The movement control devices (31 and 32) each operably engage the catheter 60 and are separately translatable along the longitudinal central axis 69.sub.CA of the catheter 60 for permitting unidirectional movement of the catheter 60 in a first axial direction 69.sub.x1 relative to the movement control devices (31 and 32).

[0074] The unidirectional nature of the movement control devices (31 and 32) (i.e., ability of each movement control device (31 and 32) to slide along the longitudinal length of the catheter 60 in a second axial direction 69.sub.x2 coupled with an inability to slide along the longitudinal length of the catheter 60 in the opposite first axial direction 69.sub.x1 along the longitudinal length of the catheter 60), allows a paired set of the movement control device (31 and 32) to quickly, easily and controllably dispense a catheter 60 from a package 20 by repetitively pushing together and pulling apart the paired set of movement control device (31 and 32). Pulling the movement control devices (31 and 32) away from one another along the longitudinal length of the catheter 60 effects longitudinal translation of the first movement control device 31 along the longitudinal length of the catheter 60 in the second axial direction 69.sub.x2 with inconsequential longitudinal translation of the second movement control device 32 along the longitudinal length of the catheter 60, while pushing the longitudinally separated movement control devices (31 and 32) towards one another along the longitudinal length of the catheter 60 effects longitudinal translation of the second movement control device 32 in the second axial direction 69.sub.x2 with inconsequential longitudinal translation of the first movement control device 31 along the longitudinal length of the catheter 60.

[0075] The dispensing device 30 may further include a handle grip 70 for facilitating single handled dispensing of the catheter 60 from the packaging 20 using the dispensing device 30, a feature long sought by users.

[0076] FIG. 8 schematically depicts an exemplary handle grip 70. Referring to FIG. 8, the handle grip 70 includes a hand graspable casing 71, and a finger actuable element 72 reciprocally (i.e., telescoping) engaged to the casing 71 for travel along a path 72p relative to the casing 71. The casing 71 and finger actuable element 72 are preferably sized, configured and arranged for thumb actuation of the finger actuable element 72 while cradling of the casing 71 within the palm of that hand. The casing 71 is fixedly attached to a second of the movement control devices 32, while the finger actuable element 72 is fixedly attached to a first of the movement control devices 31, whereby reciprocation of the finger actuable element 72 relative to the casing 71 along a path 72p effects a pulling apart and pushing together of the movement control devices 31 and 32 along the longitudinal axis 69.sub.CA of the catheter 60 so as to effect dispensing of the catheter 60 from the packaging 20.

[0077] The finger actuable element 72 may optionally be biased, such as by use of a spring, towards the pushed apart configuration to effect auto reloading of the dispensing device 30.

[0078] When the dispensing device 30 includes a handle grip 70, the packaging 20 can be conveniently heat sealed to the casing 71 with the finger actuable element 72 retained wholly within and actuated through the packaging 20.

[0079] Referring to FIG. 9, a release actuator element 80 may optionally be provided for effecting selective manual sustained pivoting of the locking member 50 on the first movement control device 31 into the aligned positioned regardless of longitudinal movement of the catheter 60 relative to the first movement control device 31 for allowing movement of a dispensed catheter 60 in the second axial longitudinal direction 69.sub.x2 and back into the packaging 20 by actuating the release actuator element 80 when the first movement control device 31 is pushed against and pivoting the locking member 50 on the second movement control device 32 into the aligned positioned.

[0080] The release actuator element 80 may be telescopingly mounted onto the finger actuable element 72 for travel as between a first disengaged positon with the release actuator element 80 spaced from the locking member 50 on the first movement control device 31 and a second engaged positon with the release actuator element 80 contacting and pivoting the locking member 50 on the first movement control device 31 into an aligned positioned.

[0081] Movement Control Device

[0082] FIGS. 1-9, and in particular FIGS. 3-7, depict a preferred embodiment of a movement control device 30 suitable for use as the movement control devices (31 and 32).

[0083] This embodiment of the movement control device 30 has a main body 40 and a locking member 50 hingedly attached to the main body 40. The main body 40 and locking member 50 are preferably formed as a monolithic device with the locking member 50 pivoting about a live hinge 55 formed in the single piece device. The locking member 40 may be made from any suitable material, including various plastics such as polyethylene, polypropylene, polyvinyl chloride (PVC), and nylon.

[0084] The main body 40 of the movement control device 30 has a first longitudinal end 41 and a second longitudinal end 42, and defines a longitudinal axis 40.sub.LA. A passageway 49 extends through the main body 40 from an opening 49i in the first longitudinal end 41 of the main body 40 to an opening 49e in the second longitudinal end 42 of the main body 40. The passageway 49 is preferably linear and defines a central axis 49.sub.CA. The passageway 49 is sized and configured to allow passage of the lumen portion of a catheter 60.

[0085] A first lateral end 51 of the locking member 50 is hingedly attached to the main body 40 at hinge 55, permitting pivoting of the locking member 50 relative to the main body 40 about a hinge pivot axis 55p as between a first aligned position depicted in FIG. 7, and a second misaligned position depicted in FIGS. 3-6. In the first aligned position the second lateral end 52 of the locking member 50 contacts the main body 40 and the central axis 59.sub.CA of an orifice 59 through the locking member 50 is aligned with the central axis 49.sub.CA of the passageway 49. When in the first aligned position a catheter 60 may be axially translated through the aligned orifice 59 and passageway 49. Pivoting of the locking member 50 from the first aligned position towards the second misaligned position pivots the second lateral end 52 of the locking member 50 away from the main body 40, resulting in an increasing misalignment of the central axis 59.sub.CA of the orifice 59 and the central axis 49.sub.CA of the passageway 49 until movement of a catheter 60 is inhibited through the misaligned orifice 59 and passageway 49.

[0086] In a preferred embodiment, laterally y spaced engagement members 43 extend longitudinally x from a longitudinal end of the main body 40, with a first lateral end 51 of the locking member 50 hingedly attached to a first 43.sub.1 of these engagement members 43 at hinge 55, and the second 43.sub.2 of these engagement members 43 located to contact the second lateral end 52 of the locking member 50 when the locking member 50 is in the first aligned position. The engagement members 43 provide a modest offset between the passageway 49 and the orifice 59 for avoiding severe bending and kinking of the catheter 60 when the central axis 59.sub.CA of the orifice 59 and the central axis 49.sub.CA of the passageway 49 are misaligned.

[0087] Pivoting of the locking member 50 about the hinge pivot axis 55p is effected by axial translation of the movement control device 30 along the longitudinal length of a catheter 60 passing through the passageway 49 and frictionally passing through the orifice 59 in the movement control device 30. Referring generally to FIGS. 1 and 2, axial translation of a movement control device 30 in the first longitudinal direction 69.sub.x1 along the length of a catheter 60 causes pivoting of the locking member 50 towards the second misaligned position so as to lock the movement control device 30 onto the catheter 60. When locked, any further movement of the movement control device 30 in the first longitudinal direction 69.sub.x1 will effect concomitant movement of the catheter 60 along with the movement control device 30 in the first longitudinal direction 69.sub.x1.

[0088] In contrast, axial translation of a movement control device 30 in the second longitudinal direction 69.sub.x2 along the length of a catheter 60 causes pivoting of the locking member 50 towards the first aligned position so as to unlock the movement control device 30 from the catheter 60. When unlocked, the movement control device 30 is free to travel along the longitudinal length of the catheter 60. Such freedom of travel can continue along the entire length of the catheter 60 in the second longitudinal direction 69.sub.x2, but will of course be promptly lost when the movement control device 30 is moved in the first longitudinal direction 69.sub.x1 as the locking member 50 will pivot into the second misaligned position and lock the movement control device 30 onto the catheter 60.

[0089] The size and dimensions of the movement control device 30 are generally dictated by the size of the catheter 60 with which it is used, but the main body 40 should be large enough to be retentively pinched between the thumb and index finger in order to allow dispensing of the catheter 60 from the packaging 20 through the movement control device 30. Dimensions of an exemplary movement control device 30 are provided in Table One below.

TABLE-US-00001 TABLE ONE (Exemplary Dimensions) DIMENSION SIZE Longitudinal Length of Main Body 40 25 mm Lateral Width of Main Body 40 20 mm Transverse Depth of Main Body 40 10 mm Cross Sectional Area of Passageway 49 200 mm.sup.2 Thickness of Locking Member 50 1-2 mm Cross Sectional Area of Orifice 59 100 mm.sup.2

[0090] Referring to FIGS. 1 and 2, when incorporated into a packaged catheter 10 at least one of the movement control devices 31 and 32 is preferably fixedly attached to the packaging 20, with a first portion 40.sub.1 of the main body 40 positioned within the product retention chamber 29 defined by the packing 20, and a second portion 40.sub.2 of the main body 40 positioned exterior to the product retention chamber 29. The passageway 49 through the main body 40 of this affixed movement control device 32 provides a port through the packaging 20 from an interior end 49i of the passageway 49 to an exterior end 49e of the passageway 49. The affixed movement control device 32 can conveniently be heat sealed at a longitudinal end 21 of the packaging 20. A cap or seal 45 can be placed over the exterior end 49e of the passageway 49. The other movement control device 31 is preferably wholly located within the product retention chamber 29 of the packaging 20 and may also be fixedly attached to the packaging 20 so long as the packaging 20 is supple enough to allow the movement control devices 31 and 32 to be pushed together and pulled apart.

Use

[0091] The packaged intermittent urinary catheter 10 can be used by patients for self catheterization. Prior to use the patient should take all sanitary procedures advised by their doctors to decrease the risks of infection.

[0092] Referring to the embodiment depicted in FIGS. 1 and 2, first the seal or cap 45 is removed to open the port through the packaging 20 defined by the passageway 49 through the main body 40 of the second movement control device 32.

[0093] The user then grasps or pinches the main body 40 of the first movement control device 31 through the packaging 20 with one hand, grasps or pinches the main body 40 of the second movement control device 32 with the other hand through the packaging 20, and then repetitively pulls the movement control devices 31 and 32 apart as depicted in FIG. 1 to load the dispensing device 30 without effecting longitudinal movement of the catheter 60 relative to the second movement control device 31, and pushes the movement control devices 31 and 32 together as depicted in FIG. 2 to dispense a length of the catheter 60 from the package 20.

[0094] Referring to the embodiment depicted in FIGS. 8 and 9, the user cradles the casing 71 in the palm of a hand with the fingers wrapped around and gripping the casing 71 and the thumb of that same hand placed upon a pad on the activation element 72. The user then uses the thumb to reciprocate the activation element 72 relative to the casing 71 along the path of travel 72p, thereby pulling the movement control devices 31 and 32 apart without effecting longitudinal movement of the catheter 60 relative to the second movement control device 32 attached to the casing 71 when the activation element 72 is moved in one direction along the path 72p, and pushing the movement control devices 31 and 32 together to dispense a length of the catheter 60 from the package 20 when the activation element 72 is moved in the opposite direction along the path 72p.

[0095] Referring to FIGS. 1 and 2, two handed pushing and pulling of the movement control devices 31 and 32 to effect dispensing of a catheter 60 may be simplified by attaching both movement control devices 31 and 32 to the packaging 20 in longitudinally spaced relationship and providing a handle opening 90 proximate each movement control device 31 and 32.

[0096] Referring to FIGS. 8 and 9, one handed pushing and pulling of the movement control devices 31 and 32 to effect dispensing of a catheter 60 may be simplified by including the handle grip 70 feature.

[0097] The dispensing device 30 also functions to preventing the fixture end 62 of the catheter 60 from advancing out of the package 20.
