Intermittent catheters are typically used by patients suffering from urinary incontinence or by individuals unable to have voluntary urination. In our highly mobile culture, the ability to have the freedom to leave home for the day or longer is an important part of life. To accommodate this need single use catheters have been developed to allow patients to perform self catheterization. To aid in the insertion of the catheter in a body cavity they are often lubricated making the handling of the catheter difficult and messy. Many catheter packages are now designed to aid in the use of the catheter and at least the funnel end of the catheter is retained in the package. This allows the user to use the package to manipulate the catheter and avoid the messy and possible insanitary handling of the actual catheter. Manipulating a slippery catheter through a plastic bag can be quite difficult even for someone with excellent dexterity. To aid in the manipulation of the catheter various devices have been conceived to assist in movement of the catheter into and out of its package.
One such device is disclosed in U.S. Pat. No. 7,458,964 to Mosler et al. Mosler et al. discloses a catheter movement control device in which the catheter passes through a locking ring retained within the passage of a housing wherein the locking ring can be tilted within the passageway as between an aligned position for allowing passage of the catheter through the passage when the catheter is translated through the passage in a first direction, and a misaligned position for resisting passage of the catheter through the passage when the catheter is translated through the passage in a second opposite direction.
The movement control device of Mosler et al. aids in dispensing of a packaged catheter, but is difficult and cumbersome to use. Dispensing of a packaged catheter equipped with the movement control device of Mosler et al. requires the user to hold the movement control device with one hand while using the other hand to grip the lubricated catheter through the packaging, typically by pinching the catheter with the thumb against the pointer and/or index finger, and push the catheter towards and through the movement control device. Gripping and pushing of a lubricated catheter through packaging is challenging, and particularly challenging for the elderly and the infirm who are the very people who tend to use urinary catheters.
Accordingly, a substantial need continues to exist for a device capable of facilitating and simplifying dispensing of a packaged catheter.
A first aspect of the invention is a packaged catheter equipped with a dispensing device. A first embodiment of the first aspect of the invention includes (i) packaging defining a product retention chamber, (ii) a catheter defining a longitudinal axis retained within the product retention chamber, and (iii) a pair of separately translatable movement control devices, each operably engaging the catheter for permitting unidirectional movement of the catheter in a first axial direction relative to the movement control devices.
A second embodiment of the first aspect of the invention includes (i) packaging defining a product retention chamber, (ii) a catheter retained within the product retention chamber and defining an insertion end, a fixture end and a longitudinal axis, and (iii) first and second separately translatable movement control devices, each operably engaging the catheter for permitting unidirectional movement of the catheter in a first axial direction relative to the movement control devices, wherein (a) pulling the movement control devices away from one another along the longitudinal axis of the catheter effects longitudinal translation of the first movement control device in a second axial direction opposite the first axial direction along the longitudinal length of the catheter with inconsequential longitudinal translation of the second movement control device along the longitudinal length of the catheter, and (b) pushing the longitudinally separated movement control devices towards one another along the longitudinal axis of the catheter effects longitudinal translation of the second movement control device in the second axial direction along the longitudinal length of the catheter with inconsequential longitudinal translation of the first movement control device along the longitudinal length of the catheter.
The first aspect of the invention can optionally be equipped with a handle grip that includes at least (i) a hand graspable casing fixedly attached to one of the movement control devices, and (ii) a finger actuable element reciprocally engaged to the casing and fixedly attached to the other movement control device, wherein reciprocation of the finger actuable element relative to the casing effects pulling apart and pushing together of the movement control devices along the longitudinal axis of the catheter so as to effect dispensing of the catheter from the packaging.
A second aspect of the invention is a method of dispensing a catheter from a packaged catheter in accordance with the first aspect of the invention wherein the movement control devices permit unidirectional movement of the catheter in a first axial direction relative to the movement control devices. A first embodiment of the second aspect of the invention includes the steps of (i) pulling the pair of movement control devices away from one another along the longitudinal axis of the catheter so as to effect longitudinal translation of a first movement control device in a second axial direction opposite the first axial direction along the longitudinal length of the catheter with inconsequential longitudinal translation of the second movement control device along the longitudinal length of the catheter, and (ii) pushing the longitudinally separated movement control devices towards one another along the longitudinal axis of the catheter so as to effect longitudinal translation of the second movement control device in the second axial direction along the longitudinal length of the catheter with inconsequential longitudinal translation of the first movement control device along the longitudinal length of the catheter, whereby (iii) pushing of the longitudinally separated movement control devices towards one another along the longitudinal axis of the catheter effects dispensing of the catheter out of the packaging.
A second embodiment of the second aspect of the invention pertains to dispensing a catheter from a packaged catheter in accordance with the first aspect of the invention which is equipped with a handle grip, and includes the steps of (i) grasping the casing of the handle grip with a first hand, and (ii) reciprocating the button along a path with a finger on the first hand, wherein (a) movement of the button in one direction along the path effects a pulling movement of the pair of movement control devices away from one another along the longitudinal axis of the catheter so as to effect longitudinal translation of a first movement control device in a second axial direction opposite the first axial direction along the longitudinal length of the catheter with inconsequential longitudinal translation of the second movement control device along the longitudinal length of the catheter, and (b) movement of the button in the other opposite direction along the path effects a pushing movement of the pair of movement control devices towards one another along the longitudinal axis of the catheter so as to effect longitudinal translation of the second movement control device in the second axial direction along the longitudinal length of the catheter with inconsequential longitudinal translation of the first movement control device along the longitudinal length of the catheter, effecting a dispensing of the catheter out of the packaging.
As utilized herein, including the claims, the term “inconsequential”, when used to describe longitudinal translation of a movement control device along the longitudinal length of a catheter, means a distance of less than 1 cm.
Construction
Referring to
Packaged Catheter
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 69CA.
Catheter
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.
Packaging
The packaging 20 may be selected from any of the customary packaging used for catheters 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.
Dispensing Device
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.
The movement control devices (31 and 32) each operably engage the catheter 60 and are separately translatable along the longitudinal central axis 69CA of the catheter 60 for permitting unidirectional movement of the catheter 60 in a first axial direction 69x1 relative to the movement control devices (31 and 32).
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 69x2 coupled with an inability to slide along the longitudinal length of the catheter 60 in the opposite first axial direction 69x1 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 69x2 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 69x2 with inconsequential longitudinal translation of the first movement control device 31 along the longitudinal length of the catheter 60.
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.
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.
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.
Referring to
The release actuator element 80 may be telescopingly mounted onto the finger actuable element 72 for travel as between a first disengaged position with the release actuator element 80 spaced from the locking member 50 on the first movement control device 31 and a second engaged position with the release actuator element 80 contacting and pivoting the locking member 50 on the first movement control device 31 into an aligned positioned.
Movement Control Device
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.
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 40LA. 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 49CA. The passageway 49 is sized and configured to allow passage of the lumen portion of a catheter 60.
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
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 431 of these engagement members 43 at hinge 55, and the second 432 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 59CA of the orifice 59 and the central axis 49CA of the passageway 49 are misaligned.
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
In contrast, axial translation of a movement control device 30 in the second longitudinal direction 69x2 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 69x2, but will of course be promptly lost when the movement control device 30 is moved in the first longitudinal direction 69x1 as the locking member 50 will pivot into the second misaligned position and lock the movement control device 30 onto the catheter 60.
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.
