Description
- This application is a division of U.S. Nonprovisional application Ser. No. 13/984,025, filed Nov. 20, 2013, which is a national stage application, filed under 35 U.S.C. § 371, of International Application No. PCT/US2012/000071, filed Feb. 8, 2012, which claims the benefit under 35 U.S.C. § 119(e) of U.S. Provisional Application No. 61/441,261, filed on Feb. 9, 2011 in the U.S. Patent and Trademark Office, the disclosures of all of said prior applications being incorporated herein by reference in their entirety.
- The present invention relates generally to infusion sets that can be inserted and attached to the skin using commercially available inserter devices.
- For patients with diabetes, there are two principal modes of daily insulin therapy. The first mode includes syringes and insulin pens. These devices are simple to use and are relatively low in cost, but they require a needle stick at each injection, typically three to four times per day. The second mode includes insulin infusion therapy, which utilizes an insulin pump. Infusion pumps, although more complex and expensive than syringes and pens, offer the advantages of continuous infusion of insulin via an infusion cannula, precision dosing, and programmable delivery schedules.
- The use of an infusion pump requires the use of a disposable component, typically referred to as an infusion set, line set, extension set or pump set, which conveys the insulin from a reservoir within the pump into the skin of the user. An infusion set typically consists, of a pump connector, a length of tubing, and a hub or base from which an infusion cannula (i.e., an infusion needle or a flexible catheter) extends. The hub or base has an adhesive which retains the base on the skin surface during use, and which may be applied to the skin manually or with the aid of a manual or automatic insertion device. In most cases, a detachable fluid connector is provided to allow the pump tubing to be disconnected from the hub or base of the infusion set when the user wishes to shower, bathe or swim.
- Some infusion sets are complex in design and do not allow for adequate user mobility or for quick and simple methods to connect and disconnect the fluid connector from the base after the base has been attached to a user, while preventing external exposure of the inserted infusion cannula.
- Accordingly, a need exists for improving infusion sets that will permit greater mobility for the user while preventing external exposure of the inserted infusion cannula.
- An object of the present invention is to provide an infusion set that provides increased mobility for the user.
- Another object of the present invention is to provide an infusion set that includes components that are able to self-close to prevent exposure of the infusion cannula.
- Another object of the present invention is to provide a fluid path that is formed in an infusion set during use, with the fluid path being closed when the infusion set is not used.
- These and other objects are substantially achieved by providing an, infusion set that provides simplicity in manufacture and use for the convenience of the user, while preventing exposure of the lumen of the inserted infusion cannula to the external environment.

FIG. 10B is a top view of the base of the infusion set ofFIG. 8A ; and -
FIG. 11 is a cross-sectional view of the exemplary infusion set ofFIG. 8A , illustrated with the housing detached from the base. - An exemplary embodiment of a flexible catheter-type infusion set 30 in accordance with the present invention is illustrated in
FIG. 1 . The infusion set is intended to be connected to an infusion pump, for the delivery of insulin or other medicament. The infusion set may be used with existing commercial inserters, such as the Medtronic Quick-serter® device, with little or no modification. -
FIG. 1 illustrates aneedle hub 40 that is positioned above anextension set 50, and abase 90 that is positioned below theextension set 50. Also illustrated is anadhesive pad 96 that is attached to an outer surface of thebase 90. Theadhesive pad 96 is configured to be attachable to a user. Also illustrated is a tube set orextension tube 60 that connects to theextension set 50. Theconnector 62 of theextension tube 60 connects to an infusion pump (not shown) such that medication such as insulin from the pump is delivered to the extension set 50. - The extension set 50 includes a
housing 70. Abutton 80 is housed in thehousing 70, as illustrated inFIG. 2 . Thebutton 80, when pressed, actuates a keyholeslot latching device 82. -
FIG. 2 illustrates an exemplary embodiment of the present invention which shows a button latching configuration of the extension set 50, in which thehousing 70, including thebutton 80, is latched onto thebase 90. In this configuration, thebutton 80 is connected to a keyholeslot latching device 82 that engages thebase retention boss 92 of thebase 90, during the infusion state, to latch thehousing 70 to thebase 90. - More specifically, the
boss 92 is mushroom-shaped and includes acap portion 93 and astem portion 95. When the keyholeslot latching device 82 is slotted between thecap 93 and the base 90 adjacent thestem portion 95, thehousing 70 is latched onto thebase 90, as illustrated inFIG. 2 , The keyholeslot latching device 82 may frictionally engage one or more of thecap portion 93,stem portion 95 and a portion of the base 90 adjacent to thestem portion 95, in the latched state, as illustrated inFIG. 2 . - The
needle hub 40 is removed from thehousing 70 after attaching aflexible catheter 42 to the user. Thereafter, when a user wishes to remove the extension set 50 from the base 90 that holds thecatheter 42, the user presses the button 80 (shown inFIGS. 2-5 ) to unlatch thehousing 70 from theretention boss 92, by actuating the keyholeslot latching device 82 to move from a latched position (seeFIGS. 2 and 4 ) to an unlatched position (seeFIGS. 3 and 5 ). In the unlatched state, the keyholeslot latching device 82 disengages from the slot position below thecap portion 93 and adjacent to thestem portion 95 of theretention boss 92, as illustrated inFIGS. 3 and 5 . - In order to unlatch the
housing 70 from the base 90 (after theneedle hub 40 has been removed), the user presses thebutton 80, in the latched state (seeFIG. 2 ), so that the button moves to a position shown inFIG. 3 , wherein the keyholeslot latching mechanism 82 becomes disengaged from its slot position below thecap portion 93 and adjacent to thestem portion 95, whereupon the extension set 50 may be separated from thebase 90. - The
button 80 is shown with greater clarity inFIGS. 4 and 5 , which depicts one configuration of a latching device, namely the keyholeslot latching device 82, with the base 90 illustrated as being transparent solely for visual clarity. The base 90 need not, in reality, be transparent as illustrated in theFIGS. 4 and 5 . In the illustrated embodiment, an integrally molded set ofplastic leaf springs 84 is actuated by the pressedbutton 80, to change from the latched state (FIGS. 2 and 4 ) to the unlatched state (FIGS. 3 and 5 ). The open ends of theleaf springs 84 are held in position byindents 86 that are positioned in thehousing 70, as illustrated inFIG. 4 . When therelease button 80 is pressed, theleaf springs 84 disengage from theindents 86, as illustrated inFIG. 5 . -
FIGS. 3 and 5 show thebutton 80 in the unlatched position. InFIGS. 3 and 5 , the keyholeslot latching device 82 has disengaged from theretention boss 92. The latching and unlatching mechanism illustrated in this embodiment uses a keyholeslot latching device 82 in which a keyhole having a smaller diameter portion and a larger diameter portion is included, wherein when the smaller diameter portion of the keyholeslot latching device 82 engages theretention boss 92, thehousing 70 is latched onto thebase 90, as illustrated inFIG. 2 , wherein the outer wall of the smaller diameter portion of the keyholeslot latching device 82 engages theretention boss 92. When thebutton 80 is pushed, this actuates the disengagement of thehousing 70 from thebase 90, and as illustrated inFIGS. 3 and 5 , theretention boss 92 is positioned at a central portion of the larger diameter of the keyholeslot latching device 82, thus disengaging thekeyhole latching device 82 from theretention boss 92. This releases thehousing 70 from thebase 90. -
FIG. 6A illustrates afluid path 64 that is formed along the tube setreceiver 74 of thehousing 70, as well as a pocket between theupper septum 110 and thelower septum 120, completed via anopening 94 in thebase 90, a slot in theintroducer needle 44, and the extension settubing 60, enabling fluid to flow from a pump (not shown) attached to theconnector 62 of the extension settubing 60 through thetip 45 of theintroducer needle 44, as illustrated inFIG. 6A . This allows theset 50 to be primed with theintroducer needle 44 in place. -
FIGS. 2, 3 and 6A illustrate the position in which the infusion set 30 can be attached to a user, either manually or with the aid of a commercially available or custom-designed inserter device. After the infusion set 30 has been attached to the user, theintroducer needle 44 is removed by manually withdrawing theneedle hub 40 from thehousing 70. With reference toFIG. 6A , when theneedle hub 40, to which theintroducer needle 44 is attached, is removed, theintroducer needle 44, which is secured to theneedle hub 40, is pulled through both theupper septum 110 and thelower septum 120. When theintroducer needle 44 moves out of theupper septum 110, theupper septum 110 self-closes its opening through which theintroducer needle 44 has been removed, but thelower septum 120 remains open due to the presence of a blunt cannula 76 (illustrated inFIG. 6B ) that extends from acentral wall 72 of thehousing 70, into thelower septum 120 in order to keep thelower septum 120 open. - After the
needle hub 40 andintroducer needle 44 have been removed from thehousing 70, the user receives medication from the pump through thefluid path 64, as shown inFIG. 6B , and out of thetip 43 of thecatheter 42. If the user seeks to remove thehousing 70 from thebase 90, for instance prior to vigorous exercise, taking a shower or bath, or swimming, the user presses thebutton 80 to release thekeyhole slot device 82 from, the latched position (seeFIGS. 2 and 4 ) to the unlatched position (seeFIGS. 3 and 5 ), thereby unlatching thehousing 70 from thebase 90. Thehousing 70 can then be detached from the base 90 when thehousing 70 is lifted from thebase 90, in the same direction as the removal of theneedle hub 40 from thehousing 70. When thehousing 70 is lifted from thebase 90, the blunt cannula that extends from thecentral wall 72 of thehousing 70 into thelower septum 120 is also removed, and thus thelower septum 120 is able to self-close its opening. Thus, when thehousing 70 is removed from thebase 90, thelower septum 120 becomes self-closed, preventing an external pathway from being formed into the inserted lumen of thecatheter 42, thereby preventing introduction of external pathogens, liquids or gases into the catheter insertion site, as illustrated inFIG. 6C . Theseptum 120 is preferably provided with a pre-formed slit to facilitate penetration by theblunt cannula 76. - After the
housing 70 has been removed from thebase 90, the blunt cannula at thecentral wall 72 of thehousing 70 can be capped or covered with a housing protective cap to prevent external exposure to the disconnectedfluid path 64, after thehousing 70 has been removed. Similarly, thebase 90 can also be capped or covered with a suitably shaped cap, such as a base protective cap (not shown). - After the
housing 70 has been removed, thecatheter 42 remains attached to thebase 90, with thelower septum 120 being self-closed (closing its hole) to prevent external contamination into thecatheter 42, after thefluid path 64 has been disconnected by the removal of thehousing 70, to which is attached the upper septum 110 (seeFIG. 6C ). - After the
housing 70 has been detached from thebase 90, the user has greater mobility to engage in vigorous exercise, swim, shower or bathe. After such activity has ended and the user wishes to reattach thehousing 70 to thebase 90, the user generally follows the following procedure. - If the
base 90 was capped, the cap is removed, and the externally exposed outer surface of the lower septum 120 (facing toward theupper septum 110 inFIG. 6A ) is sterilized by the user with any one of known methods for sterilization such as an alcohol wipe. If the blunt cannula of thecentral wall 72 was capped after the detachment of thehousing 70 from thebase 90, the cap (not shown) is then removed, and if the blunt cannula was not capped, the surface area thereof is also sterilized. Thereafter, thebutton 80 is pressed to position thehousing 70 in the unlatched position, as inFIGS. 3 and 5 . Thehousing 70 is then placed directly on the base 90 such that the blunt cannula of thecentral wall 72 of thehousing 70 extends into and opens the closed hole of thelower septum 120, as illustrated inFIG. 6B . Thebutton 80 is then released to latch thehousing 70 onto the base 90 at thebase retention boss 92, as illustrated inFIGS. 2, 4 and 6B . Thereafter, thefluid pathway 64 is reformed from the pump through thetubing 60, and into thehousing 70, through the pocket between theupper septum 110 and thelower septum 120, and out through thetip 43 of thecatheter 42, as illustrated inFIG. 6B . - Although
FIGS. 2-6 illustrate a latching device that includes thebutton 80 connected to the keyholeslot latching device 82 that is secured onto thehousing 70, any similar latching and unlatching device can be used to perform the same operation. For example, the embodiment that is illustrated inFIGS. 8-11 discloses another latching and unlatching device. -
FIGS. 7A and 7B illustrate a modifiedneedle hub 40′ to which is secured anintroducer needle 44′. Theneedle hub 40′ can have an outer diameter, height, inner diameter, and other dimensions such that it can be used with commercially available inserter devices, such as the Medtronic Quick-Set 0 inserter. - The infusion set 30′ of
FIGS. 8-11 functions substantially in the same manner as extension set 50 ofFIGS. 1-6 , but this embodiment uses a latching mechanism that is different from the keyholeslot latching device 82 andretention boss 92 ofFIGS. 1-6 . This embodiment also has an infusion set 30′ that is designed to be used with a commercially available insertion device such as the Medtronic Quick-serter® insertion device. - As illustrated in
FIGS. 8 and 9 , the infusion set 30′ includes a housing orhub 70′ that latches on to a base 90′. A release mechanism for disconnecting thehub 70′ from the base 90′ is integrated into thehub 70′ andbase 90′, rather than being an extra component therein. The release mechanism includes a pair oflevers 78, each having anarm 79. Thelevers 78 are hinged to thehub 70′ and thelevers 78 can be biased to manipulate the position of thearms 79. As illustrated inFIGS. 9-11 , the base 90′ includes radially positionedcatches 97 that form pockets 98. Thearms 79 of thelevers 78 fit into thepockets 98 and interlock with thecatches 97 in order to secure thehub 70′ to the base 90′, at one of six radial positions corresponding to each of thepockets 98. - In order to disconnect the
hub 70′ from the base 90′, the user squeezes or biases thelevers 78 of thehub 70′, to position thearms 79 out of thepockets 98 of the base 90′. Thereafter, the user can lift thehub 70′ from the base 90′, to separate the two elements, as illustrated inFIG. 11 . - In order to connect the
hub 70′ to the base 90′ the user aligns thehub 70′ adjacent the two opposingpockets 98 the user wishes to secure thearms 79 of thelevers 78, biases thelevers 78 offset from thepockets 98, rotates thehub 70′, and releases thelevers 78 to lock thearms 79 of thelevers 78 into thepockets 98 and catches 97, as illustrated inFIGS. 8 and 9 . -
FIG. 10A illustrates a top view of thehub 70′ that can attach and detach to and from the base 90′ ofFIG. 10B . As illustrated inFIG. 10B , there are six distinct rotational positions that thehub 70′ can attach to the base 90′, corresponding to each of thepockets 98 that the user can select. Such selection will determine at what angle thehub 70′ will be oriented when attached to the base 90′, and hence the direction in which the connected tubing (not shown) extends. In this embodiment, the increment of rotation that is available is 60 degrees. The number ofpockets 98 with correspondingcatches 97 will determine the rotational positions of thehub 70′ vis-à-vis the base 90′. - As illustrated in
FIGS. 8-10 , when thehub 70′ is attached to the base 90′, thepre-slit septum 120′ of the base 90′ is opened by theblunt cannula 76′. A needle path for theintroducer needle 44′ is formed when theintroducer needle 44′ penetrates thecylindrical septum 110′, theblunt cannula 76,septum 120′ and thecatheter 42′ during priming. - As illustrated in
FIG. 9 , thecylindrical septum 110′ is preferably cylindrical in shape and parallel with the tube setreceiver 74′. Theseptum 110′ provides a seal where theintroducer needle 44′ is placed, while permitting flow from thetubeset receiver 74 to theblunt cannula 76 and thecatheter 42′. The base 90′ includes anadhesive pad 96′ for attaching the base 90′ to the user, as illustrated inFIGS. 8-11 . - An advantage of this embodiment is that the release mechanism is integral to the
hub 70′ andbase 90′ and facilitates a lower profile due to fewer components. The squeeze action or biasing of thelevers 78 is user-friendly and intuitive. In addition, the integrated release mechanism is reliable since there are fewer assembly tolerances to consider, as compared with other latching mechanisms. - Although only a few exemplary embodiments of the present invention have been described in detail above, those skilled in the art will readily appreciate that many modifications are possible in the exemplary embodiments without materially departing from the novel teachings and advantages of this invention. Accordingly, all such modifications are intended to be included within the scope of this invention, as defined in the appended claims and their equivalents.
