Description

Technical Field

[0001] This application claims priority and benefit to Indian Patent Application No. 202341061291, filed on September 12, 2023, the disclosure of which is incorporated herein by reference in its entirety.

[0002] The present invention relates generally to medical catheter accessories, and more specifically to devices for assisting in the fixation of catheters. Background Technology

[0003] A catheter is a medical device that can be inserted into the body to treat diseases or perform surgical procedures. Catheters are manufactured for specific applications, such as cardiovascular, urinary, gastrointestinal, neurovascular, and ophthalmic surgical procedures. In most uses, catheters are thin, flexible tubes (soft catheters), although catheters of varying rigidity are available depending on the application. Catheters can be inserted into body cavities, tubes or blood vessels, the brain, skin, or adipose tissue. Functionally, they allow drainage, administration of fluids or gases, access with surgical instruments, and perform a variety of other tasks depending on the type of catheter.

[0004] When a catheter remains in place in a patient's body for an extended period, fixation techniques are often used to secure it in position. This is particularly true for central venous catheters (CVCs) and peripherally inserted central catheters (PICCs), which are often inserted into the superior vena cava via the patient's neck / chest and upper arm, respectively. Solutions include sutures ( Figure 1 ) and catheter fixation devices (an exemplary catheter fixation device is the STATLOCK™ device, purchased from Beckton Dickinson, Inc. (Franklin Lake, New Jersey) - see Figure 3 Using any of these techniques typically requires changing the dressing associated with the catheter insertion site. For example, in... Figures 2A to 2C As can be seen, cleaning around the catheter held in place by sutures results in incomplete (and therefore insufficient) cleaning, which in turn increases the risk of centerline-associated bloodstream infection (CLABSI).

[0005] When using a fixation device to secure a catheter, the fixation device is typically replaced at the same time as dressing changes. During dressing changes, replacement of the fixation device, and cleaning of the insertion site, caregivers should avoid excessive movement of the catheter (e.g., the catheter tip may migrate or leave its original position at the insertion site, which could result in the catheter being fully displaced and no longer correctly positioned within the vein or intended anatomical location). This is particularly important for certain catheters and sites, such as CVCs and PICCs.

[0006] Different techniques are currently used to temporarily secure catheters during dressing changes using adhesive-based attachment devices such as STATLOCK™. In one technique, caregivers can attempt to hold the catheter in place using their fingers. Figure 4A However, this may require a second caregiver to clean the area, while the first caregiver holds the catheter in place with one hand after removing the attachment device, while lifting the extension cord with the other. Furthermore, this technique does not conform to the Aseptic Non-Touch Technique (ANTT) protocol. Alternatively, a roll-up dressing method can be used to temporarily hold the catheter while replacing the attachment device. Figure 4B However, inconsistencies may exist in the use of roll-up dressings (e.g., how much dressing is rolled up). As a third technique, secondary fastening components (such as adhesive strips) can be used to temporarily hold the catheter in place during fastening removal and replacement. Figure 4C This requires caregivers to be aware of this and to adhere to the protocol for using adhesive strips during dressing changes. Experience shows that this protocol is often overlooked due to several limitations, such as the difficulty in removing the adhesive strip and / or the potential for movement toward the catheter, and in some cases, the adhesive strip leaves behind residue on the catheter lumen that can attract contaminants / microorganisms after removal.

[0007] It may be necessary to provide techniques to improve adherence to protocols, which in turn can improve patient outcomes. Summary of the Invention

As used herein, phrases such as “approximately X to Y” mean “approximately X to approximately Y”.

[0042] Referring now to the accompanying drawings, the components used for catheter fixation and replacement are generally indicated by 10 and... Figure 5 As shown in the figure. Components of assembly 10 include a primary catheter fixation device 12 and a secondary catheter fixation device 20. The secondary catheter fixation device 20 is used to fix the catheter C (e.g., CVC) at the insertion site (proximal) or distally on the extension line behind the catheter hub when changing dressings, and the primary catheter fixation device 12 replaces the existing primary catheter fixation device.

[0043] The primary catheter fixation device 12 can be any catheter fixation device known to be suitable for fixing catheters. Figure 5 An example is shown. More specifically, the primary catheter fixation device 12 has a body 13, a pin 14 or other fastening feature for securing the catheter thereto, and a lower adhesive surface designed to adhere to the patient's skin. Exemplary embodiments of the primary fixation device 12 are described in U.S. Patents 7,223,256, 9,561,348, 8,743,400, and 11,020,565, the disclosures of which are incorporated herein by reference in their entirety.

[0044] Secondary catheter fixation device 20 in Figure 6 and Figure 7 As shown in the diagram, the secondary conduit attachment device 20 includes a main strip 22. A lumen anchor 24 with clips 25 is attached to the central region of the underside of the main strip 22. The clips 25 are sized and configured to receive and hold the lumen therein. An adhesive surface 26 is located on the underside of the main strip 22 on either side of the lumen anchor 24. In some embodiments, the adhesive surface 26 may be covered with a backing layer to prevent undesirable adhesion of the device 20 prior to use. Figure 8 The illustration shows catheter C being restrained between clips 25 when the secondary catheter fixation device 20 adheres to the patient's skin.

[0045] The use of component 10 in Figures 9A to 9G The diagram is shown in the image. Figure 9A A catheter C is shown in place on a patient's skin. The catheter C is secured in place, with its wings W held in place by pins 14 in the orifice H of the catheter C. The insertion site of the lumen L for the catheter C is covered by a small dressing D suitable for the insertion site (an exemplary dressing is the GuardIVa™ dressing, available from Beckton Dickinson). A transparent dressing 50 covers the insertion site, the catheter C, the dressing D, and the primary securing device 12.

[0046] When dressing D needs to be changed, remove transparent dressing 50 and also remove dressing D. Figure 9B Then catheter C is secured in place, and secondary catheter securing device 20 ( Figure 9C and Figure 9D An adhesive dressing 26 is applied between the primary fixation device 12 and the insertion site. The lumen L of the catheter C is received in the clamp 25, and the adhesive surface 26 is adhered to the skin. The primary fixation device 12 is then separated from the catheter C, and the area previously covered by the transparent dressing 50 is cleaned. Figure 9E ).

[0047] Once cleaning is complete, the new primary fixation device 12' is applied to the skin, and catheter C is reattached to the new primary fixation device 12'. The secondary catheter fixation device 20 is then removed. Figure 9F Apply the new dressing D' to the insertion site, and while the catheter C is held in place by the new primary fixation device 12, apply the new transparent dressing 50' over the new dressing D' and the catheter C. Figure 9G ).

[0048] As described above, one reality of the process of changing dressings and primary fixation devices is that caregivers, often under time pressure, may not follow the complete protocol (e.g., they may not bother to use adhesive strips to anchor the fixation device due to some of the disadvantages mentioned above). In view of this, it would be beneficial to provide components of component 10 in a package that can encourage adherence to the protocol (and / or prevent failure to adhere to the appropriate protocol). Such a package in Figure 10 As shown, and generally indicated by 100. (See also...) Figure 10 As can be seen, the packaging 100 includes an upper compartment 101 and a lower compartment 102. The upper compartment 101 is generally box-shaped and is covered by a peelable cover 110. The peelable cover 110 may be transparent or partially transparent to show the items stored in the upper compartment 101. In some embodiments, the peelable cover 110 may include features for indicating whether the peelable cover 110 has been damaged or tampered with. Examples of such features include: color-changing sealant, holographic or other image-based indicators, electronic circuitry (e.g., RFID antennas), physical seals, or similar devices. Figure 10As shown in the example, the secondary fastener 20 is stored in the upper compartment 101. The lower compartment 102 is attached to the upper compartment 101 such that they share at least a portion of a common wall 104 (e.g., the bottom plate of the upper compartment 101 serves as part of the top plate of the lower compartment 102). The lower compartment 102 is also box-shaped. A barrier 120 is disposed in the common wall 104, which can be removed (e.g., by tearing along one or more notches) to provide access to the lower compartment 102. The primary fastener 12 is stored in the lower compartment 102. The barrier 120 may be transparent or partially transparent to show the items stored in the lower compartment 102. In some embodiments, the barrier 120 may include features indicating whether the barrier 120 has been damaged or tampered with. Examples of such features include: color-changing sealant, holographic or other image-based indicators, electronic circuitry (e.g., RFID antennas), physical seals, or similar devices. In some embodiments, the barrier 120 may be formed of the same material as the peelable cover 110. In some embodiments, barrier 120 may be formed of a different material than the peelable cover 110. For example, barrier 120 may be formed of a material capable of supporting at least the weight of the articles stored in the upper compartment. Furthermore, if the articles in the upper compartment include edges or friction elements, barrier 120 should be formed of a material with sufficient strength to withstand tearing during normal transport of package 100. Barrier materials may be (but are not limited to) paper, including recycled paper, single or multiple polymer films and (one or more) adhesive layers or metal films / foils composed of polypropylene, polyethylene, nylon, polyethylene terephthalate, etc. Since the packaging material comes into direct contact with the medical device, it is preferably composed of biocompatible, non-toxic, inert materials that will not leach any harmful trace amounts of material during storage, transport, or use.

[0049] It will be apparent to those skilled in the art that a user accesses the components within the packaging 100 by first removing the peelable cover 110 to open the upper compartment 101, an action that provides access to the secondary fastener 20 located in the upper compartment 101. At this point, the lower compartment remains inaccessible. The user can then remove the barrier 120 from the lower compartment 102 to access the primary fastener 12 within the lower compartment 102. Because the lower compartment 102 is inaccessible until the barrier 120 is removed (or at least partially removed), the user cannot access the primary fastener 12 without first accessing the secondary fastener 20 in the upper compartment 101.

[0050] As can be seen from the above discussion, the configuration of Package 100 encourages users to follow... Figures 9A to 9GThe steps are illustrated in the figure. Due to the design of the package 10, the user can only access the primary fastener 12 by first removing the secondary fastener 20. This reminds the user (a) to use the secondary fastener 20 to anchor the conduit before removing the old primary fastener 12, and (b) to do so in the proper order (i.e., the user should attach the secondary fastener 20 to the conduit before replacing the primary fastener 12).

[0051] Because the primary fastener 12 and the secondary fastener 20 are typically located in a healthcare environment, the package 100 should be configured to prevent contamination of the upper compartment 101 and the lower compartment 102 (e.g., to ensure they are aseptically packaged). The package 100 also allows the use of the first article to perform the first phase of a protocol while retaining a second article for subsequent phases within a sealed container. This ensures that if problems arise during the first phase, the second article remains sterile and may be available for later use.

[0052] Furthermore, those skilled in the art will understand that other “forced sequence” packaging configurations are also possible. For example, in some embodiments, barrier 120 may be essentially the base of upper compartment 101, with an openable window in the top panel of lower compartment 102, rather than barrier 120 being a peelable panel. In this case, the entire upper compartment 101 (including its base) may need to be detached from lower compartment 102 (by tearing, sliding, peeling, etc.) to allow the user access to lower compartment 102.

[0053] As another example, the primary and secondary fastening devices can be positioned in a compartment arranged side-by-side (see [reference]). Figure 12 In this arrangement, compartment 140, which houses the primary fastener, is sealed off from compartment 130, which houses the secondary fastener, by a barrier 135 between the compartments (e.g., on a common sidewall of the compartments), preventing access to the primary fastener compartment. Alternatively, the primary fastener compartment may be covered by a peelable web, and both the primary and secondary fastener compartments may be covered by a second peelable web superimposed on the first peelable web. In this arrangement, removal of the second peelable web allows access to the secondary fastener, but the first web remains in place and must be peeled off separately to allow access to the first fastener.

[0054] Those skilled in the art will appreciate that, although the first and second compartments are shown in the accompanying drawings and described herein, packages according to some embodiments of the invention may include more than two compartments configured to be opened in a specific order and / or following a particular scheme. Furthermore, such packages may include both compartments with components in a specific order and compartments without a specific order. Moreover, the compartments are not limited to the rectangular box-like configuration shown herein, but may alternatively be spherical, hemispherical, oval, triangular, hexagonal, or similar shapes.

[0055] It is also conceivable that the upper compartment 101 may include markings or other signs on its exterior or interior to guide or instruct users on how to approach the lower compartment 102. Such markings may be visible before approaching the upper compartment (e.g., printed on the cover 110) or may only be visible after approaching the upper compartment 101. In some embodiments, each compartment of package 100 (or a large portion of package 100) may include indicators for identifying protocols associated with materials stored in package 100. Indicators may be machine-readable indicators, such as quick-read codes, barcodes, or other scannable elements for protocol identification. Indicators may be human-perceptible, such as shape or color. The use of human-perceptible indicators may be beneficial in care settings where emergency action may be required. In such cases, unique colors may be associated with specific emergency protocols to allow machines or people to more quickly identify appropriate emergency supplies.

[0056] Those skilled in the art will appreciate that the package 100 can be used with other types of components. As an example, in some cases, the secondary fastening device 20 shown above can be replaced with adhesive strips. As another example, in some cases, the scheme may require the primary fastening to be applied first, and the secondary component applied after the primary fastening. In this case, the package will be configured such that the secondary component is only accessible after the primary component has been approached and removed. Various different secondary fastening devices are described in Indian Provisional Patent Applications 202441028018 (filed April 4, 2024) and 202441028019 (filed April 4, 2024), the disclosures of which are incorporated herein by reference in their entirety.

[0057] In any of the described embodiments, the compartments of package 100 may be formed from recyclable materials such as plastic-based or paper-based materials.

[0058] Those skilled in the art will appreciate that packaging 100 and other packaging described herein can be used to contain other components, whether they are other medical components or non-medical articles, in which a user may be encouraged to follow a protocol or series of steps to properly use these components. Examples include, but are not limited to, skin or device disinfection products, such as wipes or disinfectant applicators, adhesive removal devices for easy removal of IV catheter dressings and / or attachment devices, skin moisturizers, and tissue adhesives for sealing IV catheter inlet sites into the skin.

[0059] The packaging according to embodiments of the invention is typically formed by the following steps: forming a first compartment; positioning a first component in the first compartment; forming a second compartment attached to the first compartment; positioning a second component in the second compartment; and closing the first and second compartments. The first and second compartments are configured such that the second compartment can be accessed via the first compartment after the first compartment has been accessed. In some cases, the first and second compartments (or portions thereof) may be formed and / or closed simultaneously, or may be formed at different times. In some cases, the formation of the first compartment may be completed as part of the second compartment is formed (i.e., it may be closed) (e.g., if a barrier layer is applied to close the first compartment). Other variations are also possible.

[0060] The foregoing description is illustrative of the invention and should not be construed as limiting it. Although exemplary embodiments of the invention have been described, those skilled in the art will readily appreciate that many modifications are possible in the exemplary embodiments without substantially departing from the novel teachings and advantages of the invention. Therefore, all such modifications are intended to be included within the scope of the invention.
