Description

Rotary peritoneal dialysis interconnection device

Technical Field

This document generally, but not exclusively, relates to the connection and disconnection of piping systems within a housing resistant to touch contamination.

Background Technology

Peritonitis remains a significant challenge in the management of end-stage renal disease patients on peritoneal dialysis, with a substantial impact on morbidity and mortality. Bacterial colonization on the skin or mucous membranes is a potential complication of infection. One approach involves patient training; however, many patients discontinue these training sessions after a short period, rendering this strategy unreliable.

Summary of the Invention

The inventors have recognized that, among other things, the problem to be addressed may include touch contamination. The high risk of touch contamination is associated with connecting and disconnecting the peritoneal catheter and the machine. It requires handwashing, wearing a mask, cleaning the delivery kit, removing the cap from both the disposable kit and the patient delivery kit, and then connecting the disposable kit to the patient delivery kit without contaminating either end. Maintaining sterility is crucial, and in the event of an interruption of sterility, some medical facilities automatically require a three-day course of intraperitoneal antibiotics.

This topic includes solutions to the problem of touch contamination. One example includes a housing with an internal environment configured to prevent touch contamination. The housing includes a first portion, such as a cover portion, configured to rotate independently of a second portion, such as a cavity portion. The first and second portions have alignment positions, which in one example include a first position for removing a first cover from the fitting, a second position for connecting with a corresponding connector to enable fluid delivery, and a third position for attaching a replacement or second cover to the fitting. Configurations such as keys and keyways, and engagement features such as clamps and lugs, allow for controlled movement of system components in a manner that reduces contamination and allows for dialysis.

Each of these non-restricted examples can exist independently, or can be combined with one or more examples from other examples in various permutations or combinations.

This overview is intended to provide an overview of the subject matter of this patent application. It is not intended to provide an exclusive or exhaustive explanation of the invention. Detailed descriptions are included to provide further information about this patent application.

Detailed Implementation

Figure 1 illustrates the connections associated with the PD device. A permanent catheter 10 is attached to the patient via a permanent connector. The end of the permanent catheter 10 is connected to the end of a delivery kit 20. The delivery kit 20 terminates at an end with a disposable cap 30. The delivery kit 20 is sometimes referred to herein as tube 20. In use, the disposable cap 30 is manually removed, and the delivery kit 20 is connected to a solution reservoir via a disposable tube 40. In the figure, a separator is provided at the end of tube 40, and a branch connection of the separator is connected to a discharge bag via a discharge conduit 50.

Examples of this topic include a housing attached to tube 40. A fitting that attaches to delivery kit 20 instead of cover 30 allows for attachment to the housing in a manner that reduces the incidence of touch contamination.

Figure 2 illustrates an example of a method 200 with a configuration suitable for using this subject matter. Method 200 can be implemented using a device connected to a pipe, such as pipe 40. The housing includes a cover portion and a cavity portion. The interior of the housing includes a cap remover, a fluid connector, and a second cap. The cap remover is configured to remove a first cap from the delivery kit. The fluid connector is configured to allow fluid delivery. The second cap is configured to be positioned on the end of an assembly connected to the delivery kit.

At 205, method 200 includes aligning the delivery kit connector with a cap remover. The delivery kit connector, sometimes referred to as the fitting, is coupled to the housing via a receiver port located in a portion of the housing. The portions of the housing are aligned such that the fitting is positioned by the cap remover within the housing. The cap remover may include a clamp that engages with a feature of a first cap already attached to the fitting. The fitting can be manipulated by rotation, forward pushing, or some other movement to engage the cap remover with the cap on the fitting. Further manipulation of the fitting, such as the manipulation indicated at 210, removes the first cap from the fitting and exposes the lumen of the fitting.

At 215, the housing is manipulated to align the fitting with the fluid connector within the housing. This fluidly connects the lumen of the fitting, exposed by removing the first cover, to the fluid connector. The fitting can be engaged with the fluid connector by rotation, by pushing forward, or by other manipulation methods, as shown at 220.

When the fitting and fluid connector are connected, the dialysis procedure is performed. When dialysis is complete, this subject can then be manipulated again to disconnect from the fluid connector, as shown at 225.

After dialysis, the device is manipulated to mount a replacement cap onto the delivery unit's fitting. At 230, the housing is manipulated to align the fitting with the second cap. The second cap is carried within the housing. At 235, the fitting is manipulated to engage with the second cap. At 240, the fitting and the second cap are removed from the housing together.

Figure 3 illustrates a view of an interconnect device according to an example. Figure 3 illustrates a housing 300 having a first portion 310, also referred to as a cover portion 310, and a second portion 320, also referred to as a cavity portion. The housing 300 includes an internal chamber that can be considered as free from touch contamination. As shown, the cover portion 310 includes a receiver port 325. The receiver port 325 is configured to receive a mount 315. The receiver port 325 includes a through keyway 340 and a blind keyway 345. The mount 315 includes a key 335 configured to extend through the keyway 340 for a certain length, and when the key 335 engages with the keyway 340, the key 335 prevents the mount 315 from rotating relative to the receiver port 325. In the example shown, the range of the key 335 is limited such that rotation is prevented when the key 335 engages with the keyway 340, and the mount 315 is free to rotate when the key 335 disengages from the keyway 340.

In the illustration, a first cover is disposed at the lower end of the fitting 315. The first cover includes a radially projecting lug 330, which is shown here positioned to align with the key 335 and the through keyway 340.

The fitting 315 includes an insertion stop 25. The insertion stop 25 includes a flange that provides a stop for limiting the insertion depth of the fitting 315 in the receiver port 325. Additionally, the insertion stop 25 includes a contoured peripheral feature to facilitate rotation and manipulation of the fitting 315 relative to the receiver port 325. As shown, a tube 20 is coupled to the fitting 315. In one example, the tube 20 is coupled to the fitting 315 via a hose barb. A tube 45 is coupled to a connector attached to the cavity portion 320 of the housing 300.

Figure 4 illustrates a view of an interconnecting device according to an example. In the example shown, housing 300 includes a cover portion 310 and a cavity portion 320 aligned on a rotation axis 10. The cover portion 310 and cavity portion 320 are connected together by fasteners 12, which may be threaded or unthreaded, to allow the cover portion 310 to rotate independently of the cavity portion 320. As shown, the cover portion 310 includes a receiver port 325. The receiver port 325 includes a through keyway 340 and a blind keyway 345.

Figure 5 illustrates a view of a portion of an interconnect device according to an example. In the figure, a blind keyway 345 of the receiver port 325 is shown as having an open channel at the bottom edge and a closed channel at the top edge. The extent of the blind keyway 345 restricts the travel of the fitting 315 relative to the receiver port 325 in a linear direction indicated by the reverse arrow 6, by which the fitting 315 is removed from the receiver port 325. The keyway 345 also prevents rotation of the fitting 315, ensuring that the fitting 315 is correctly oriented in a third alignment position to receive a replacement cover. The keyway 340 allows the fitting 315 to travel relative to the receiver port 325 in a forward linear direction as indicated by arrow 4 and in a backward or reverse linear direction as indicated by arrow 6. The keyway 340 also ensures proper alignment with the retaining clamp 920. In the example shown, the fastener 12 can be considered as a pin, a self-tapping screw, a snap-fit connection, or other structure.

Figure 6 illustrates a view of a mounting 315 according to an example. As shown, the mounting 315 is positioned adjacent to the cover 540. The mounting 315 is coupled to the tube 20 and includes an insertion stop 25. Additionally, a key 335 is shown located on the outer diameter of the mounting 315, and an internal keyway 355 is shown located on the end of the mounting 315. The internal keyway 355 is configured to receive a bayonet lug 520 of the cover 540.

The cover 540 includes radially projecting lugs 330. Additionally, the cover 540 includes a washer 530. In one example, the washer 530 includes a resilient O-ring. Furthermore, the cover 540 includes a resilient O-ring 510.

The cover 540 is configured to engage with the mount 315 by means of a lug 520 that engages with the keyway 355. When fully engaged with the keyway 355, the lug 520 is bottomed out in the contoured keyway, and the lug 330 is positioned to align with the key 335 of the mount 315. The cover 540 prevents the ends of the mount 315 from being contaminated by touch.

Figure 7 illustrates a view of a fitting 315 that fully engages and seats the cover 540 according to an example. As shown, the lug 330 is aligned with the key 335. In the configuration shown, the fitting 315 can engage with the receiver port 325, and both the lug 330 and the key 335 pass unobstructed through the keyway 340.

Figures 8A, 8B, and 8C illustrate views of a cover 540 according to an example. In the illustrated example, the cover 540 includes a washer 530 adjacent to a flanged end. The washer 530 may include a resilient seal, such as an O-ring. The cover 540 includes radially projecting bayonet lugs 520.

Figure 9 illustrates a view of the cavity portion 320 of a housing 320 according to an example. In the figure, the cavity portion 320 includes a cap remover stud 910 and a cap remover clamp 920. The cap remover stud 910 provides a centering aid for keeping the cap 540 aligned during insertion. The cap remover clamp 920 is configured to engage a lug 330 during a portion of a rotation. The allowed portion of a rotation is smaller than the portion of the mount rotating. The cap 540 rotates together with the mount 315 until it reaches a limiting portion of the clamp where the cap 540 stops rotating. Thereafter, the mount 315 continues to rotate relative to the cap 540. This aligns the bayonet lug 520 with the opening of the mating keyway 355 to reach the outside of the mount 315, thereby allowing the cap 540 to be removed. The reverse is true for resealing.

A cap remover stud 910 is disposed within the cavity portion 320 at a first alignment position. The cavity portion 320 includes a fluid connector 930 disposed at a second alignment position. The fluid connector 930 is configured to engage with the fitting 315 and provides a fluid-tight connection between the lumen of the fluid connector 930 and the lumen of the fitting 315. The lumen of the fitting 315 is fluidly connected to the lumen of the tube 20, and thus provides a fluid-tight connection between the tube 20 and the tube 40.

Cavity portion 320 includes a second cover 940 disposed at a third alignment position. The second cover 940 is configured to engage with the fitting 315 and provide a contactless connection. The second cover 940 is disposed adjacent to a second cover clamp 950. The clamp 950 provides a form-fit engagement between the fitting 315 and the second cover 940. Like cover 540, the second cover 940 includes a resilient O-ring for providing a contactless connection. In the figures, the cover portion 310 is omitted for clarity.

The cavity portion 320 and the cover portion (not shown) are connected in a manner that allows one to rotate independently relative to the other. Additionally, a spring plunger 960 is provided inside the cavity portion 320. This spring plunger 960 is configured as a spring-loaded plunger, and when the plunger engages with the corresponding structure of the cover portion, the spring plunger 960 provides a stop defining a first alignment position, a second alignment position, and a third alignment position. When the cover portion is in the first alignment position, the fitting 315 aligns with the cap remover 910; when the cover portion is in the second alignment position, the fitting 315 aligns with the fluid connector 930; and when the cover portion is in the third alignment position, the fitting 315 aligns with the second cap 940.

Figure 10 illustrates a view of a portion of a housing according to an example. The figure shows a portion of the receiver port 325 protruding from the underside of the cover portion 310. The figure also shows a blind keyway 345 and a through keyway 340.

Axis 10 passes through the center of the cover portion 310, and the figure shows a support boss for engaging with a corresponding feature of the cavity portion (not shown) for connection and independent rotation of the various parts of the housing.

The figure also illustrates a contoured track 1030 located on the lower side of the cover portion 310. A spring plunger 960 (FIG. 9) engages with the contoured surface of the track 1030. Additionally, each of the stop portions 1020 includes a recess for engaging and marking a portion of the spring plunger 960. Furthermore, the ratchet mechanism 1010 includes a feature that allows rotational movement in a selected direction and prevents rotational movement in the opposite direction.

Figure 11 illustrates a view of cavity portion 320 according to an example. For clarity, cover portion 310 is omitted. The figure illustrates the fitting 315 in a first alignment position, in which cap 540 engages with the lumen of fitting 315, and thus tube 20 is also sealed. Second cap 940 is visible inside cavity portion 320. Fluid connector 930 is connected to tube 45 and is visible inside cavity portion 320.

Figure 12 illustrates a view of cavity portion 320 according to an example. For clarity, cover portion 310 is omitted. The figure illustrates the fitting 315 positioned in a second alignment position, in which cap 540 is disengaged from fitting 315 by cap remover clamp 920 and held within cavity portion 320. Additionally, fitting 315 is positioned to align and engage with a fluid connector for fluid communication with tube 45. Second cap 940 is visible within the interior of cavity portion 320.

Figure 13 illustrates a view of the cover portion 310, in which the fitting 315 engages with the receiver port 325. In the figure, the key 335 is substantially away from the keyway of the receiver port 325. Also as shown, the fitting 315 engages with the cover 540. As shown, the receiver port 325 is configured to be off-center relative to the central axis 10.

Additional notes

The components described in this article can be made from a variety of materials. For example, the housing can be manufactured from a polymer using a molding process, or from metal using a machining or casting operation. In one example, the selected component is manufactured using additive manufacturing technology.

Manufacturing may include forming a housing having a cavity portion and a cover portion. The functional elements described in this document may be configured as illustrated, or may be configured differently. For example, the figures illustrate a profiled track disposed on the inner end wall of the housing, with a spring plunger configured to apply a stopping force in a direction parallel to the central axis of the housing. In other configurations, the profiled track is disposed on different surfaces. For example, the profiled track may be disposed on the inner sidewall of the housing, and the spring plunger may apply a stopping force in an outward radial direction. As another example, the profiled track may be disposed on the outer surface of a central post aligned with the central axis, and the spring plunger may be configured to apply a stopping force in an inward radial direction.

The first and second portions of the housing can be constructed in a manner different from that illustrated herein. For example, the cover portion may include a cavity, or the housing may be manufactured from two covers and a central segment. In one example, the housing portions are configured for rotational movement in which one portion is configured to move independently of the other portion.

In some examples, fasteners that rotate a portion—including clamps and studs, or clamps and lugs—are replaced by a combination of helical threads on the outer and inner cylindrical surfaces.

An example of this subject includes a system having a housing configured for rotational movement. The housing includes a cavity portion and a cover portion. The cover portion may be configured for rotational movement relative to the cavity portion. The cover portion may include a receiver port configured to engage with a fitting configured for coupling to an end of a first tube.

The key and keyway are configured to allow the fitting to undergo a first limited rotation relative to the receiver port for a first insertion depth and to allow the fitting to undergo a second limited rotation relative to the receiver port for a second insertion depth. At a first alignment position of the cavity portion relative to the cover portion, the receiver port is aligned with a first retaining clamp. Additionally, a keyway 340 in the receiver port 325 is aligned with the fitting 315 such that a cover lug is aligned for engagement with a retaining clamp 920. The retaining clamp may include a fastener that rotates a small portion and is configured to engage with a corresponding lug or stud. A first cover may be coupled to the fitting. The lug and first retaining clamp are configured to disengage the first cover from the fitting via rotation and longitudinal movement of the fitting relative to the receiver port. At a second alignment position of the cavity portion relative to the cover portion, the receiver port is aligned with a fluid connector. The fluid connector is configured to engage the fitting and provide a fluid-tight connection between the lumen of the fitting and the lumen of the fluid connector. At a third alignment position of the cavity portion relative to the cover portion, the fitting is aligned with a second cover. The second cover is configured to engage the lumen of the fitting and provide a leak-proof seal for the lumen of the fitting.

In one example, the fluid connector includes a resilient O-ring.

In one example, the second cap includes a resilient O-ring.

In one example, the second cover includes a bayonet lug configured to engage with a fitting.

In one example, the housing includes a guide portion having a stop portion corresponding to a first alignment position, a second alignment position, or a third alignment position.

In one example, the guide includes a track configured to allow the cover portion to rotate unidirectionally relative to the cavity portion.

One example includes a method. The method may include forming a housing having a first portion and a second portion, wherein the first portion has a receiver port configured to receive an accessory and a first cover coupled to the accessory. The accessory has an accessory lumen. The first and second portions are configured for independent rotation and have a first alignment position, a second alignment position, and a third alignment position, wherein the first alignment position, the second alignment position, and the third alignment position are different. The method includes forming a first clamp on the housing to engage with a first lug of the first cover corresponding to the first alignment position. The first clamp and the first lug are configured to engage selectively and are also configured to disengage the first cover and the accessory by a first movement of the accessory relative to the receiver port.
