Description

[Technical Field]

[0001] FIELD OF THE DISCLOSURE The present disclosure relates to fixation devices for catheter assemblies, kits including fixation devices, and methods of using fixation devices. [Background technology]

[0002] Catheter assemblies may be used for a variety of purposes, such as for pumping, insufflation, and / or fluid removal. In some cases, catheter assemblies may be used to administer medications and fluids to a patient. Such catheter assemblies typically include a cannula that is inserted into the patient's skin at an insertion site. The catheter assembly may need to be secured to the patient's skin to prevent movement of the catheter assembly. For example, the catheter assembly may be secured to the patient's skin to prevent the catheter assembly from being withdrawn or otherwise moved in a manner that may adversely affect the function of the catheter assembly.

[0003] Catheter assemblies are typically secured to a patient's skin using conventional securement units, such as tapes, patches, and sutures. However, conventional securement units may not adequately secure the catheter assembly to the skin. Specifically, such securement units may not adequately stabilize the catheter assembly, which can result in undesirable movement of the catheter assembly during use. In some cases, conventional securement units can result in various complications, such as dislodgement and accidental removal of the catheter assembly from the patient's skin, phlebitis, extravasation / infiltration, leakage, blockage, and bloodstream infection.

[0004] A fixation unit, such as a tape or patch, may allow partial or minute movement of the catheter assembly, which can lead to patient discomfort. Furthermore, the use of sutures to secure the catheter assembly to the skin can lead to suture-related infections and complications. In some cases, a clinician may need to access the insertion site of a cannula, for example, to perform a maintenance procedure around the insertion site. However, conventional fixation units may not allow access to the area around the insertion site. Furthermore, a clinician may need to remove the fixation unit to access the insertion site, which can cause a piston movement of the cannula and may require additional effort to stabilize the cannula and other components of the catheter assembly. Therefore, an improved fixation device may be needed to overcome the above-mentioned problems of conventional fixation units and methods. Summary of the Invention

[0005] Generally, the present disclosure relates to fixation devices for catheter assemblies, kits including fixation devices, and methods of using fixation devices.

[0006] In a first aspect, the present disclosure provides a fixation device for a catheter assembly having a catheter hub and a cannula configured to be inserted into a patient's skin at an insertion site.

[0011] In the following description, reference is made to the accompanying drawings, which form a part hereof, and in which various embodiments are shown by way of illustration. It is to be understood that other embodiments are contemplated and may be made without departing from the scope and spirit of the present disclosure. Accordingly, the following detailed description is not to be taken in a limiting sense.

[0012] In the disclosure that follows, the following definitions are adopted:

[0013] As used herein, all numbers should be considered to be modified by the term "about." As used herein, "a," "an," "the," "at least one," and "one or more" are used interchangeably.

[0014] The term "generally," when used herein as a modifier to a characteristic or attribute, unless specifically defined otherwise, means that the characteristic or attribute is readily recognizable by one of ordinary skill in the art, but does not require absolute precision or perfect agreement (e.g., within + / - 20% for quantifiable characteristics).

[0015] The term "substantially," unless otherwise specifically defined, means a high degree of approximation (e.g., within + / - 10% for quantifiable properties), but again does not require absolute precision or perfect agreement.

[0016] The term "about," unless otherwise specifically defined, means a high degree of approximation (e.g., within + / - 5% for quantifiable properties), but again does not require absolute precision or exact agreement.

[0017] Terms such as same, equal, uniform, constant, exactly, etc. are understood to not require absolute precision or exact agreement, but rather within normal tolerances or measurement errors applicable to a particular situation.

[0018] As used herein, the terms "first" and "second" are used as identifiers. Therefore, such terms should not be construed as limiting the present disclosure. The terms "first" and "second" when used in conjunction with a feature or element are interchangeable throughout multiple embodiments of the present disclosure.

[0019] As used herein, "at least one of A and B" should be understood to mean "A only, B only, or both A and B."

[0020] Unless otherwise specified or limited, the terms "mounted," "connected," and "coupled," and variations thereof, are used broadly and encompass both direct and indirect mounting, connecting, and coupling.

[0021] As used herein, the terms "layer," "sheet," and "dressing," or variations thereof, are used to describe an article that has a small thickness relative to its length and width.

[0022] As used herein, the term "polymer" refers to both a material prepared from one monomer (e.g., a homopolymer) or a material prepared from two or more monomers (e.g., a copolymer, a terpolymer, etc.). Similarly, the term "polymerizing" refers to the process of making a polymeric material, which may be a homopolymer, copolymer, terpolymer, etc. The term "copolymer" refers to a polymeric material prepared from at least two different monomers.

[0023] As used herein, the term "insertion site" refers to the location where the cannula of the catheter is inserted into the patient's skin.

[0024] As used herein, the term "maintenance procedure" generally refers to a procedure that involves cleaning and / or disinfecting the patient's skin proximal to the insertion site. Maintenance procedures may be performed by medical personnel at regular intervals during intravenous therapy, for example.

[0025] As used herein, the terms "pistoning" or "pistoning movement" refer to the movement of the cannula of a catheter relative to the insertion site.

[0026] As used herein, the term "inserted through the skin," when used in conjunction with the term "cannula" or "catheter," refers to the insertion of a catheter or cannula through a patient's skin. For example, the distal end of the catheter or cannula may be located in any desired anatomical location, including, by way of non-limiting example, within the lumen of a vein and / or artery, within the atrium and ventricle of the heart, within a ventral body cavity, within the spinal canal, within the subarachnoid space, within the intracranial space, and within fat and / or muscle tissue.

[0027] Catheter assemblies may be used for administering medications and fluids to a patient, for providing air, and / or for removing fluids. Such catheter assemblies may need to be secured to the patient's skin to prevent movement of the catheter assembly. For example, the catheter assembly may be secured to the patient's skin to prevent the catheter assembly from being withdrawn or otherwise moved in a manner that may adversely affect the function of the catheter assembly. Such catheter assemblies typically include a cannula that is inserted into the patient's skin at an insertion site.

[0028] Conventional fixation units, such as tapes, patches, and sutures, may not adequately secure the catheter assembly to the patient's skin. Specifically, conventional fixation units may not adequately stabilize the catheter assembly, thereby allowing undesirable movement of the catheter assembly during use. In some cases, the use of conventional fixation units can lead to various complications, such as dislodgment and accidental removal of the catheter assembly from the patient's skin, phlebitis, extravasation, blockage / infiltration, leakage, and bloodstream infection. Fixation units, such as tapes or patches, may allow partial or minute movement of the catheter assembly, which can lead to patient discomfort. Furthermore, the use of sutures to secure the catheter assembly to the skin can lead to suture-related infections and complications.

[0029] In some cases, a clinician may need to access an insertion site, for example, to perform maintenance procedures around the insertion site. However, conventional fixation units may not allow access to the area around the insertion site. More specifically, a clinician may need to remove the fixation unit to access the insertion site, which may cause the cannula to piston and may require additional effort to stabilize the cannula or other portions of the catheter assembly. Therefore, an improved fixation device may be needed to overcome the above-mentioned problems of conventional fixation units and methods.

[0030] The present disclosure provides a fixation device for a catheter assembly having a catheter hub and a cannula configured to be inserted into a patient's skin at an insertion site. The fixation device includes a base assembly configured to be removably secured to the patient's skin. The base assembly includes a base mount. The base assembly is fixedly coupled to the base mount and further includes a slider track including a first coupling feature. The first coupling feature includes a first arcuate shape along a length of the first coupling feature. The fixation device further includes a hub assembly slidably coupled to the base assembly. The hub assembly includes a hub slider including a second coupling feature complementary to the first coupling feature. The second coupling feature includes a second arcuate shape along a length of the second coupling feature similar to the first arcuate shape of the slider track. The length of the second coupling feature is shorter than the length of the first coupling feature. The second coupling feature at least partially slidably engages the first coupling feature such that the hub slider is slidable relative to the base assembly along the slider track. The hub assembly further includes a hub base fixedly coupled to the hub slider and disposed on the hub slider on an opposite side of the slider track. The hub base is configured to be removably secured to the catheter hub and cannula. Furthermore, the hub assembly is slidably movable relative to the base assembly along the slider track to a desired position. The present disclosure also relates to kits including the fixation device and methods of using the fixation device.

[0031] The slider track and hub slider together may allow movement of the hub assembly relative to the base assembly. Therefore, a clinician may easily access the insertion site for maintenance procedures, such as cleaning procedures. Furthermore, the design of the slider track and slider channel may prevent pistoning of the cannula when the hub assembly is moved to different positions along the slider track. The fixation device allows easy and quick positioning of the hub assembly at any desired position through a sliding force applied to the hub assembly. Furthermore, the minimum distance defined between the insertion site and the hub base is constant at any position of the hub assembly along the slider track. Therefore, the fixation device eliminates any possibility of pistoning / movement of the cannula when moving the hub assembly.

[0032] The fixation device securely secures the catheter assembly on the patient's skin. Specifically, the fixation device may securely secure various components of the catheter assembly (such as the catheter hub, lumen, and cannula) to the patient's skin. The fixation device may prevent migration of the catheter assembly, eliminating the need for any additional tape, patches, or sutures. Note that once the fixation device is in place on the patient's skin, additional dressings may not be necessary.

[0033] Furthermore, the base of the base assembly may be removably secured to the patient's skin. The base includes one or more pull tabs that can be grasped by a user, such as a clinician / healthcare professional. The pull tabs may be pulled to detach the base from the skin. An adhesive layer securely secures the base to the patient's skin. The adhesive layer may include a stretch-release adhesive such that pulling the pull tab causes the adhesive layer to lose its adhesive properties. The base may then be easily peeled away, allowing the securement device to be removed from the patient's skin without causing discomfort to the patient. Furthermore, the securement device may prevent the catheter assembly from falling off or accidentally removing from the patient's skin.

[0034] Thus, the fixation device of the present disclosure can securely secure the catheter assembly to the patient's skin, inhibit unwanted movement of the catheter assembly, prevent infection at the insertion site, facilitate easy removal of the fixation device after use, and allow the clinician easy access to the area around the insertion site without removing the fixation device or pistoning the cannula.

[0035] Referring now to the figures, Figure 1A shows a schematic perspective view of a fixation device 100 for a catheter assembly 10, in accordance with one embodiment of the present disclosure. In the illustrated embodiment of Figure 1A, the catheter assembly 10 is positioned on the skin 12 of a patient 14. As shown in Figure 1A, the catheter assembly 10 includes a catheter hub 16 and a cannula 18 configured to be inserted into the skin 12 of the patient 14 at an insertion site 20. Further, the cannula 18 is at least partially received within the catheter hub 16.

[0036] The catheter assembly 10 further includes at least one lumen 22 at least partially received within the catheter hub 16. In the illustrated embodiment of FIG. 1A, the at least one lumen 22 includes three lumens 22. In other words, the catheter assembly 10 is a three-lumen catheter assembly 10. However, the number of lumens 22 may vary based on the desired application and / or infusion characteristics. The lumen 22 is fluidly connected to the cannula 18.

[0037] In the illustrated embodiment of Figure 1A, the catheter hub 16 includes a pair of opposing wings 24 and one or more holes 26. Specifically, in the illustrated embodiment of Figure 1A, the catheter hub 16 includes a hole 26 corresponding to each of the pair of opposing wings 24.

[0038] In some embodiments, the catheter assembly 10 may include a central venous catheter (CVC). A CVC may be referred to as a central line, central venous line, or central venous access catheter. A CVC may be used to access a large, centrally located vein (not shown), which is often required for critically ill patients, for patients requiring long-term intravenous therapy for reliable vascular access, and for administering fluids that may harm small peripheral veins. Thus, in some embodiments, at least a portion of the cannula 18 may be inserted into a vein located in the neck (e.g., the internal jugular vein), a vein located in the chest (e.g., the subclavian vein or the axillary vein), or a vein located in the groin (e.g., the femoral vein) of the patient 14. In some embodiments, the catheter assembly 10 may include a peripherally inserted central venous catheter (PICC). A PICC may be suitable for insertion into a vein located in the arm of the patient 14. However, the catheter assembly 10 may include any suitable type of catheter, which may be selected based on desired application characteristics.

[0039] Thus, the catheter assembly 10 may be used to administer intravenous therapy (e.g., medications or fluids for parenteral nutrition), to obtain blood for analysis, and / or to provide an access point for blood-based therapies such as dialysis or apheresis. The catheter assembly 10 may also be used to measure one or more characteristics of the blood (e.g., "central venous oxygen saturation"), to administer fluids or blood products for large-scale emergency fluid therapy, and / or to measure central venous pressure.

[0040] As shown in FIG. 1A , the fixation device 100 includes a base assembly 102 configured to be removably secured to the skin 12 of a patient 14. The base assembly 102 includes a base mount 104. The base mount 104 has a substantially tapered shape. Specifically, the base mount 104 tapers toward the insertion site 20. The base assembly 102 further includes a slider track 106 fixedly coupled to the base mount 104. The slider track 106 includes a first coupling feature 108. The first coupling feature 108 includes a first arcuate shape 110 along a length L1 (shown in FIG. 2 ) of the first coupling feature 108. The length L1 is embodied herein as a curved length.

[0041] The fixation device 100 further includes a hub assembly 112 (shown in FIGS. 1A and 4) slidably coupled to the base assembly 102. The hub assembly 112 is slidably movable relative to the base assembly 102 along a slider track 106 to a desired position. The hub assembly 112 includes a hub slider 114 (shown in FIGS. 2, 3A, 3B, and 4). The slider track 106 and the hub slider 114 together may enable movement of the hub assembly 112 relative to the base assembly 102. The sliding movement of the hub assembly 112 may allow a clinician to easily access the insertion site 20 for maintenance procedures, such as cleaning procedures. Specifically, the clinician may have access to a 360-degree area around the insertion site 20. Furthermore, the design of the slider track 106 and the hub slider 114 may prevent pistoning of the cannula 18 when the hub assembly 112 is moved to any position along the slider track 106. The hub assembly 112 further includes a hub base 116 fixedly coupled to the hub slider 114 and disposed on the opposite side of the slider track from the hub slider 114. The hub base 116 is configured to be removably secured to the catheter hub 16 and the cannula 18.

[0042] Further, the base assembly 102 includes a base 118. The base 118 is substantially oval-shaped. The base 118 may be a passive dressing. In other words, in some embodiments, the base 118 may be non-occlusive. However, in some embodiments, the base 118 may be an interactive dressing. In other words, in some embodiments, the base 118 may be semi-occlusive or occlusive. In some embodiments, the base 118 may function as a barrier against bacterial intrusion. In some embodiments, the base 118 may maintain hydration of the area of ​​the skin 12 to which the base 118 is removably secured and may reduce infection in the area of ​​the skin 12 to which the base 118 is removably secured.

[0043] The base 118 may include a stretchable polymeric material. The base 118 may be made of a stretchable material that can conform to a contoured surface (e.g., the skin 12 of the patient 14). Thus, in some embodiments, the base 118 may be configured to exhibit high elasticity. In some embodiments, the base 118 can have a high tensile strength, a low elastic recovery, and a high elongation at break.

[0044] In some embodiments, the base 118 may comprise at least one of a polymeric film, a polymeric foam, a polymeric hydrocolloid, and a polymeric alginate. In some embodiments, the base 118 may comprise polyolefins such as polyethylene, including high-density polyethylene, low-density polyethylene, linear low-density polyethylene, and linear very-low-density polyethylene, polypropylene, and polybutylene; vinyl copolymers such as polyvinyl chloride and polyvinyl acetate, both plasticized and unplasticized, and polyvinyl acetate; olefin copolymers such as ethylene / methacrylate copolymers, ethylene / vinyl acetate copolymers, acrylonitrile-butadiene-styrene copolymers, and ethylene-propylene copolymers; acrylic polymers and copolymers; and combinations thereof. In some embodiments, the base 118 may be in the form of a monolayer or multilayer film, non-woven films, porous films, foam films, and combinations thereof. In some embodiments, the base 118 may be fabricated using any suitable film-forming method, such as extrusion, co-extrusion, solvent casting, foam molding, or nonwoven techniques.

[0045] The base 118 includes one or more pull tabs 120 that can be grasped by a user, such as a clinician or medical professional. The pull tabs 120 can be pulled to separate the base 118 from the skin 12. The pull tabs 120 allow the base 118 to be grasped for application and removal of the fixation device 100 and also allow the clinician or any other medical professional to peel back a release liner 122 (shown in FIG. 1B ) to apply the fixation device 100 onto the skin 12 of the patient 14. To remove the base 118 from the skin 12 of the patient 14, the base 118 can be stretched by grasping and pulling the pull tabs 120. Thus, the base 118 can be easily removed from the skin 12 of the patient 14 by stretching the base 118 by grasping the pull tabs 120. The pull tabs 120 are located along a portion of the periphery of the base 118. 1A, the base 118 includes two pull tabs 120 located at opposite ends 119, 121 of the base 118. The pull tabs 120 are adhesive-free areas such that the pull tabs 120 do not attach to the skin 12 of the patient 14. In some examples, the pull tabs 120 may include indicia such as an arrow that indicates the direction in which the pull tab 120 needs to be pulled to remove the fixation device 100. The indicia may also include text such as "PULL" in addition to the arrows.

[0046] FIG. 1B shows a schematic cross-sectional view of the base assembly 102. For clarity and understanding, the thicknesses of various components of the base assembly 102 are exaggerated. With reference to FIGS. 1A and 1B, the base 118 includes a first major surface 126 fixedly coupled to the base mount 104 opposite the slider track 106 and a second major surface 128 opposite the first major surface 126. The base assembly 102 further includes a release liner 122. In some embodiments, the release liner 122 does not cover the pull tab 120. The base assembly 102 further includes an adhesive layer 130 at least partially disposed on the second major surface 128 and configured to releasably secure the base assembly 102 to the skin 12 of the patient 14. Note that the pull tab 120 is absent the adhesive layer 130.

[0047] In some embodiments, the adhesive layer 130 comprises a stretch-release adhesive. In some embodiments, the adhesive strength of the stretch-release adhesive may be less than the cohesive strength of the stretch-release adhesive, such that stretching the base 118 may essentially eliminate the adhesive ability of the stretch-release adhesive. Specifically, the tackiness of the stretch-release adhesive may be lost upon stretching of the base 118. Thus, by pulling on the base 118, the adhesive layer 130 loses its adhesive properties. The base 118 can then be easily peeled away, allowing the fixation device 100 to be removed from the skin 12 of the patient 14. The base assembly 102 can be easily removed from the skin 12 of the patient 14 without causing discomfort to the patient 14. Furthermore, the base assembly 102 may prevent the catheter assembly 10 from falling off or accidentally removing from the skin 12 of the patient 14.

[0048] 2, the slider track 106 includes a pair of end walls 132 circumferentially spaced from one another and disposed at respective opposite ends 134, 136 of the slider track 106. Each of the pair of end walls 132 is configured to engage the hub slider 114 to limit sliding movement of the hub slider 114 at the respective opposite ends 134, 136 of the slider track 106.

[0049] 1A and 2, the slider track 106 has a first center of curvature C1. Additionally, the hub assembly 112 includes a hub slider 114. The hub slider 114 includes a second coupling feature 138 that is complementary to the first coupling feature 108. The second coupling feature 138 includes a second arcuate shape 140 along a length L2 of the second coupling feature 138 that is similar to the first arcuate shape 110 of the slider track 106. The length L2 of the second coupling feature 138 is shorter than the length L1 of the first coupling feature 108. The length L2 is embodied herein as a curved length. The second coupling feature 138 at least partially slidably engages the first coupling feature 108 such that the hub slider 114 is slidable relative to the base assembly 102 along the slider track 106. Furthermore, the second coupling feature 138 at least partially frictionally engages the first coupling feature 108 such that removal of the sliding forces F1, F2 against the hub assembly 112 causes the hub slider 114 to rest relative to the slider track 106. Note that the sliding force F1 is applied in a direction opposite to the direction in which the sliding force F2 is applied. The fixation device 100 may enable easy and quick positioning of the hub assembly 112 at any desired position based on the sliding forces F1, F2 applied to the hub assembly 112 by the slider track 106 and the hub slider 114. Furthermore, the hub slider 114 has a second center of curvature C2 that coincides with the first center of curvature C1 of the slider track 106.

[0050] 2 and 3A , the base mount 104 includes an arcuate guide rail 142 spaced from the slider track 106. Furthermore, the hub base 116 includes an engagement feature 144 configured to slidably engage with the guide rail 142 of the base mount 104. As the hub slider 114 slides relative to the slider track 106, the engagement feature 144 correspondingly slides along the guide rail 142. The engagement feature 144 is embodied herein as a protrusion extending from the hub base 116. The engagement feature 144 is arcuate in shape and corresponds to the shape of the guide rail 142. In other examples, the engagement feature 144 may include a groove or slot defined by the hub base 116 instead of a protrusion. Furthermore, the base mount 104 may also include one or more indicia indicating a direction in which the hub slider 114 can be moved to position the hub assembly 112 in a desired position.

[0051] 3A and 3B show cross-sectional views of the hub slider 114 coupled to the slider track 106. As shown in FIGS. 3A and 3B, the first coupling feature 108 is fixedly coupled to the base mount 104 and includes a first portion 146 extending from the base mount 104.

The base portion 154, the pair of side portions 156, and the pair of retaining portions 162 define a slot 163 therebetween. The slot 163 at least partially receives the second portion 152 of the first coupling feature 108 such that the second portion 152 is at least partially slidably engaged with the base portion 154, the pair of side portions 156, and the pair of retaining portions 162. It should be noted that the second coupling feature 138 may include, but is not limited to, components of any other design or arrangement.

[0053] 1A and 4 , the hub base 116 defines a first end 164 and a second end 166 opposite the first end 164. The hub base 116 further includes a hub receiving portion 168 configured to removably secure the catheter hub 16 therein. The hub receiving portion 168 defines a base surface 170. The hub base 116 further includes one or more stabilizing lugs 172 extending from the base surface 170. The hub base 116 includes two stabilizing lugs 172. The stabilizing lugs 172 are arranged in a manner such that the stabilizing lugs 172 together can accommodate the catheter hub 16 therein. The stabilizing lugs 172 can engage with the catheter hub 16 to secure the catheter hub 16 within the hub receiving portion 168. In some examples, the stabilizing lugs 172 can engage with the catheter hub 16 to limit any movement of the catheter hub 16 relative to the base surface 170. In some embodiments, the stabilizing lug 172 may align with the hole 26 of the catheter hub 16 to receive the stabilizing lug 172 within the hole 26 .

[0054] The hub receiving portion 168 further includes a peripheral wall 174 separating the hub receiving portion 168 from the cannula receiving portion 176. The peripheral wall 174 extends orthogonally from the base surface 170. The peripheral wall 174 and the base surface 170 together define a receiving space 178 within the hub receiving portion 168 such that the catheter hub 16 is received within the receiving space 178 and rests on the base surface 170. Additionally, the peripheral wall 174 includes a locking member 180 at the first end 164 of the hub base 116. The peripheral wall 174 further includes a cannula opening 182 extending therethrough. The cannula opening 182 is configured to at least partially receive the cannula 18 therethrough.

[0055] The peripheral wall 174 further includes at least one lumen opening 184 extending therethrough and disposed opposite the cannula opening 182. The at least one lumen opening 184 is configured to at least partially receive at least one lumen 22 of the catheter assembly 10 therethrough. The peripheral wall 174 includes three lumen openings 184 herein. However, the total number of lumen openings 184 may vary based on the number of lumens 22.

[0056] Hub base 116 further includes a cannula receiving portion 176 that is disposed adjacent hub receiving portion 168 and is configured to at least partially removably secure cannula 18 therein. Cannula receiving portion 176 extends from hub receiving portion 168. Cannula receiving portion 176 includes a first slot 186 configured to at least partially receive cannula 18.

[0057] The hub assembly 112 further includes a hub cap 188 configured to be removably coupled to the hub receiving portion 168 of the hub base 116. The hub cap 188 is shown in an open position in FIG. 1A and in a closed position in FIG. 5. When the hub cap 188 is coupled to the hub receiving portion 168, the hub cap 188 and the hub receiving portion 168 removably secure the catheter hub 16 therebetween. The hub cap 188 is pivotally coupled to the hub receiving portion 168 at the first end 164 of the hub base 116 and is pivotally movable relative to the hub receiving portion 168 independently of the cannula cap 190. Specifically, the hub base 116 includes a living hinge 192 that pivotally couples the hub cap 188 to the hub receiving portion 168. The hub cap 188 is removably coupled to the hub receiving portion 168 at the second end 166 of the hub base 116. Specifically, the hubcap 188 defines a cavity (not shown) that receives the locking member 180 of the hub receiving portion 168 to lock the hubcap 188 with the hub receiving portion 168. It should be noted that any other technique may be used to removably couple the hubcap 188 with the hub receiving portion 168.

[0058] Additionally, the hub base 116 includes a cannula cap 190 that is separate from the hub cap 188 and configured to be removably coupled to the cannula receiving portion 176 of the hub base 116. The cannula cap 190 is shown in an open position in FIG. 1A and in a closed position in FIG. 5. Because the cannula cap 190 is separate from the hub cap 188, a user may be able to access the catheter hub 16 without opening the hub cap 188. When the cannula cap 190 is coupled to the cannula receiving portion 176, the cannula cap 190 and the cannula receiving portion 176 removably secure the cannula 18 therebetween. The cannula 18 remains removably secured to the cannula receiving portion 176 even when the hub cap 188 is pulled away from the hub receiving portion 168 and the catheter hub 16 is removed from the hub receiving portion 168. Cannula cap 190 is pivotally coupled to cannula receiving portion 176 at first end 164 of hub base 116 and is pivotally movable relative to cannula receiving portion 176 independently of hub cap 188. Cannula cap 190 is removably coupled to cannula receiving portion 176 at second end 166 of hub base 116.

[0059] Cannula cap 190 includes a second slot 194. When cannula cap 190 is removably coupled to cannula receiving portion 176, second slot 194 is at least partially aligned with first slot 186. Furthermore, when cannula 18 is inserted into first slot 186 and cannula cap 190 is removably coupled to cannula receiving portion 176, first slot 186 and second slot 194 collectively at least partially receive cannula 18 between first slot 186 and second slot 194 such that cannula 18 is removably secured to cannula receiving portion 176.

[0060] 4, fixation device 100 includes a first sleeve 196 at least partially received in first slot 186 and a second sleeve 198 at least partially received in second slot 194. When cannula 18 is inserted into first slot 186 and cannula cap 190 is removably coupled to cannula receiving portion 176, first sleeve 196 and second sleeve 198 each frictionally engage cannula 18 such that cannula 18 is removably secured between cannula receiving portion 176 and cannula cap 190 (see FIG. 1A). Such frictional engagement of cannula 18 may prevent any unintentional removal of cannula 18 from cannula receiving portion 176.

[0061] 5 and 6 show schematic perspective views of hub cap 188 and cannula cap 190, each in a closed position. FIG. 5 shows hub assembly 112 in a centered position, i.e., when hub assembly 112 is centered relative to slider track 106. Further, with reference to FIG. 6, when a sliding force F1 is applied to hub assembly 112, hub assembly 112 may be positioned proximal to end 119 of base 118 and farther from end 121 of base 118. Further, when a sliding force F2 is applied to hub assembly 112, hub assembly 112 may be positioned proximal to end 121 and farther from end 119. Note that as hub slider 114 slides along slider track 106, hub assembly 112 can rotate about pivot axis P1, which passes through first center of curvature C1 (see FIGS. 2, 3A, 3B, and 4). In some embodiments, each of the first center of curvature C1 and the second center of curvature C2 is positioned at the insertion site 20 such that the pivot axis P1 passes through the insertion site 20. Furthermore, a minimum distance D1 defined between the pivot axis P1 and the hub base 116 is constant at any position of the hub assembly 112 along the slider track 106. Furthermore, an exposed length L3 of the cannula 18 between the hub base 116 and the insertion site 20 is substantially constant at any position of the hub assembly 112 along the slider track 106. Furthermore, because both the minimum distance D1 and the exposed length L3 remain constant at any position of the hub assembly 112 along the slider track 106, the fixation device 100 eliminates any possibility of pistoning / movement of the cannula 18 when the hub assembly 112 is moved to different positions.

[0062] The fixation device 100 securely secures the catheter assembly 10 on the skin 12 of the patient 14. Specifically, the fixation device 100 may securely secure various components of the catheter assembly 10 (such as the catheter hub 16, the lumen 22, and the cannula 18 as shown in FIG. 1A ) on the skin 12 of the patient 14. Furthermore, the fixation device 100 may prevent undesired movement of the catheter assembly 10. As a result, the fixation device 100 may prevent various complications that may arise due to minute movements of the catheter assembly 10. Furthermore, the fixation device 100 may eliminate the need for any additional tape, patch, or suture to secure the catheter assembly 10. Furthermore, the fixation device 100 may facilitate easy removal of the fixation device 100 after use.

[0063] Additionally, the sliding of the hub assembly 112 relative to the base assembly 102 may allow a clinician to easily access the area around the insertion site 20 without removing the fixation device 100. For example, a clinician may access a 360-degree area around the insertion site 20 without removing the fixation device 100. The fixation device 100 may also prevent infection of the insertion site 20. Additionally, the fixation device 100 may provide improved comfort to the patient 14 during use.

[0064] Figure 7 illustrates another embodiment of the present disclosure. Specifically, Figure 7 illustrates a slider track 706 that is substantially similar to slider track 106 described in connection with Figures 1A-4 and a hub slider 714 that is substantially similar to hub slider 114 described in connection with Figures 1A-4. Slider track 706 includes a first coupling feature 708 that is substantially similar to first coupling feature 108 (see Figures 1A and 2). Additionally, hub slider 714 includes a second coupling feature 738 that is substantially similar to second coupling feature 138 (see Figure 2).

[0065] However, the slider track 706 includes a plurality of locking portions 701 disposed on the first coupling feature 708 at a corresponding plurality of locking positions along the length L4 of the first coupling feature 708. Each of the plurality of locking portions 701 is configured to releasably engage with the second coupling feature 738 to lock the hub slider 714 with the slider track 706 at the corresponding locking position. Furthermore, the hub assembly 112 (see FIGS. 1A, 4, 5, and 6) is configured to be secured in a selected one of the plurality of locking positions. Thus, the locking portion 701 may enable locking of the hub assembly 112 in any one of the plurality of locking positions. In some examples, the plurality of locking positions may include, but are not limited to, three discrete locking positions. Furthermore, the hub slider 714 includes at least one opening 703 for receiving a corresponding locking portion 701. Specifically, the hub slider 714 includes a single opening 703. The opening 703 is substantially rectangular. It should be noted that the slider track 706 or the hub slider 714 may include any other design or arrangement of components that may enable the hub slider 714 to lock with the slider track 706. In an alternative example, the locking portion 701 may be located on the second coupling feature 738 of the hub slider 714.

The clinician may remove the release liner 122 (see FIG. 1B) and removably attach the fixation device 100 onto the skin 12 (see FIG. 1A). Thus, the catheter assembly 10 may be secured and stabilized. Optionally, the clinician may also apply a window dressing over the insertion site 20 to provide additional protection against infection of the insertion site 20.

[0069] 9 shows a flowchart of a method 900 of using a fixation device 100 with a catheter assembly 10 having a catheter hub 16 and a cannula 18 inserted into the skin 12 of a patient 14 at an insertion site 20. The fixation device 100 includes a base assembly 102 configured to be removably secured to the skin 12 of the patient 14, and a hub assembly 112 slidably coupled to the base assembly 102 and configured to be removably secured to the catheter hub 16 and the cannula 18. The base assembly 102 includes a slider track 106. Further, the hub assembly 112 includes a hub slider 114 slidable along the slider track 106 of the base assembly 102. The method 900 will now be described with reference to FIGS. 1A and 9.

[0070] 1A and 9, in step 902, the base assembly 102 is removably secured to the skin 12 of the patient 14. Further, removably securing the base assembly 102 to the skin 12 of the patient 14 includes removably adhering the base 118 of the base assembly 102 to the skin 12 of the patient 14 via an adhesive.

[0071] In step 904, the catheter hub 16 and cannula 18 of the catheter assembly 10 are removably secured to the hub assembly 112. Removably securing the cannula 18 of the catheter assembly 10 to the hub assembly 112 further includes inserting the catheter hub 16 into the hub base 116 of the hub assembly 112. Removably securing the cannula 18 of the catheter assembly 10 to the hub assembly 112 further includes removably coupling a hub cap 188 to the hub base 116 such that the catheter hub 16 is secured between the hub base 116 and the hub cap 188. Removably securing the cannula 18 of the catheter assembly 10 to the hub assembly 112 further includes inserting the cannula 18 into a first slot 186 of a cannula receiving portion 176 of the hub assembly 112. The cannula receiving portion 176 is disposed adjacent to the hub base 116. Furthermore, removably securing the cannula 18 of the catheter assembly 10 to the hub assembly 112 further includes removably coupling the cannula cap 190 to the cannula receiving portion 176 such that the first slot 186 of the cannula receiving portion 176 and the second slot 194 of the cannula cap 190 collectively, at least partially, receive the cannula 18 between the first slot 186 of the cannula receiving portion 176 and the second slot 194 of the cannula cap 190.

[0072] In step 906, the hub assembly 112 is slid relative to the base assembly 102 to a desired position along the slider track 106. The exposed length L3 of the cannula 18 between the hub assembly 112 and the insertion site 20 remains substantially constant at any position of the hub assembly 112 along the slider track 106.

[0073] In step 908, once the hub assembly 112 is positioned in the desired location, a maintenance procedure is performed proximal to the insertion site 20. Additionally, the catheter hub 16 is removed from the hub base 116 while the cannula 18 is still secured to the cannula receiving portion 176. Further, removing the catheter hub 16 from the hub base 116 includes pulling the hub cap 188 away from the hub base 116 while the cannula cap 190 is still coupled to the cannula receiving portion 176.
