The embodiments described herein relate generally to medical devices and, more particularly, to devices and methods for stabilizing vascular access devices such as intravenous catheters and/or extension sets.
Many medical procedures and/or surgical interventions include inserting an access device or fluid transfer device into a portion of the body. For example, catheters and/or other lumen-defining devices can be inserted into and/or through vascular structures to access portions of the body or to transfer fluids from or to a patient. In some instances, vascular access devices (VADs) such as, for example, peripheral intravenous catheters (PIVs), are inserted into patients (e.g., when a patient is hospitalized or during other medical procedures) and are designed and/or intended to remain within the patient for an extended period.
VADs typically include a catheter formed from a soft bio-reactive polymer that is partially disposed in the body and that is attached, at a proximal end (e.g., the end outside of the body) to a hub, which in turn, can provide an interface for attaching any suitable device. After placing the VAD (e.g., a PIV catheter or the like) within a vein (or artery) of the patient, it is often desirable to stabilize and/or secure the VAD relative to the patient. For example, in some instances, movement of the VAD relative to the patient can result in undesirable bending, flexing, and/or kinking of the catheter. In other instances, movement of the VAD (e.g., along a longitudinal axis of the VAD) can withdraw a portion of the catheter from the patient's body, which in turn, can expose that portion of the catheter to an unsterile environment. Moreover, moving the VAD back to its original position can disposed the potentially contaminated portion of the VAD catheter in the patient, thereby increasing the chances of infection.
Stabilizing and/or securing devices are often used in an effort to minimize movement of a placed or indwelling VAD (e.g., PIV catheter). Some known stabilizing and/or securing devices, however, are complicated and/or time consuming to use, while others may provide inadequate stabilization. In addition, the shape and/or configuration of some known stabilizing and/or securing devices can negatively impact a flow rate through a portion the VAD and/or the vein (or artery) in which the catheter is disposed.
Thus, a need exists for improved devices and methods for stabilizing placed vascular access devices.
Devices and methods for stabilizing placed or indwelling vascular access devices such as, for example, intravenous or arterial catheters are described herein. In some embodiments, an apparatus includes a stabilization device configured to stabilize an access device when a distal end portion of the access device is inserted through a target location of a patient and at least partially disposed within a portion of the patient. The stabilization device can include a coupling surface, a proximal surface, and a base surface. The coupling surface is configured to be placed in contact with an adapter coupled to a proximal end portion of the access device. The proximal surface forms at least one angle and is configured to facilitate securement of the stabilization device to the target location of the patient. The base surface forms a contoured portion configured to be placed in contact with the target location and a recessed portion configured to be spaced apart from the target location when the contoured portion is in contact with the target location. The stabilization device is configured to be secured to the target location of the patient such that (1) the adapter is retained in a fixed position relative to the coupling surface and (2) the access device is stabilized relative to the target location.
In some embodiments, an apparatus includes a stabilization device configured to stabilize an access device when a distal end portion of the access device is inserted through a target location of a patient and at least partially disposed within a portion of the patient. The stabilization device can include a coupling surface, a proximal surface, and a base surface. The coupling surface is configured to be placed in contact with an adapter coupled to a proximal end portion of the access device. The proximal surface forms at least one angle and is configured to facilitate securement of the stabilization device to the target location of the patient. The base surface forms a contoured portion configured to be placed in contact with the target location and a recessed portion configured to be spaced apart from the target location when the contoured portion is in contact with the target location. The stabilization device is configured to be secured to the target location of the patient such that (1) the adapter is retained in a fixed position relative to the coupling surface and (2) the access device is stabilized relative to the target location.
In some embodiments, an apparatus includes a stabilization device configured to stabilize a vascular access device at least partially disposed within a vein of a patient. The stabilization device includes a base surface and a coupling surface. The base surface forms a contoured portion configured to be placed in contact with a target location of the patient and a recessed portion configured to be at least partially aligned with and spaced apart from the vein of the patient when the contoured portion is in contact with the target location. The coupling surface is configured to be placed in contact with an adapter coupled to a proximal end portion of the vascular access device. The coupling surface includes a first portion and a second portion. The first portion includes at least one protrusion configured to selectively engage the adapter such that (1) a portion of the adapter is aligned with and configured to be placed in contact with the second portion of the coupling surface when the first portion of the coupling surface is in contact with a distal end portion of the adapter, and (2) the portion of the adapter is misaligned with and spaced apart from the second portion of the coupling surface when the first portion of the coupling surface is in contact with a proximal end portion of the adapter.
In some embodiments, a method of stabilizing a vascular access device at least partially disposed within a vein of a patient includes coupling a stabilization device to the vascular access device at least partially disposed in the vein of the patient. The stabilization device is positioned on a target location of the patient such that a recessed portion formed by a base surface of the stabilization device is aligned with the vein. A first strip of medical tape is applied to a proximal surface of the stabilization device such that each of a first end portion and a second end portion of the first strip of medical tape are in contact with the target location of the patient and are distal to a medial portion of the medical tape. The medial portion of the first strip of medical tape is at least partially in contact with the proximal surface of the stabilization device and at least partially in contact with the target location of the patient. A second strip of medical tape is applied to a portion of the stabilization device distal to the proximal surface such that the second strip of medical tape partially overlaps at least the first end portion and the second end portion of the first strip of medical tape.
In some embodiments, a stabilization device has a proximal end portion and a distal end portion and is configured to be secured to the skin of a patient. The proximal end portion includes a proximal surface forming at least one angle configured to facilitate securement of the stabilization device to the skin of the patient. A base surface of the stabilization device forms a contour that is configured to be placed in contact with the skin of a patient, and defines a recess along the contour configured to be spaced apart from the skin of the patient. The stabilization device is configured to couple to at least one of a hub of a placed vascular access device or an adapter coupled to the placed vascular access device to stabilize the placed vascular access device when the stabilization device is secured to the skin of the patient.
As used in this specification, the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, the term “a member” is intended to mean a single member or a combination of members, “a material” is intended to mean one or more materials or a combination thereof, “a device” is intended to mean a single device or a combination of devices.
As used herein, the terms “about” and “approximately” can be used interchangeably and generally mean plus or minus 10% of the value stated. For example, about 0.5 would include 0.45 and 0.55, about 10 would include 9 to 11, about 1000 would include 900 to 1100.
Similarly, the term “substantially” when used in connection with a geometric construction and/or geometric relationship is intended to convey that the structure and/or relationship so defined is nominally the recited structure and/or relationship. As one example, a first portion of a stabilization device that is described as being “substantially perpendicular” to a second portion of the stabilization device is intended to convey that, although a perpendicular relationship (e.g., being arranged, disposed at, and/or otherwise forming a 90° angle or orientation) is desirable, some variance or non-perpendicularity can occur in a “substantially perpendicular” relationship. As another example, two geometric constructs that are described as being substantially aligned is intended to convey that, although alignment of the geometric constructs is desirable, some variance or misalignment can occur. In some instances, variances such as those described above can result from, for example, manufacturing tolerances, or other practical considerations. Thus, a geometric construction modified by the term “substantially” includes such geometric properties within a tolerance of plus or minus 5% of the stated geometric construction. For example, a “substantially perpendicular” relationship is a relationship between two geometric constructs that is within plus or minus 5% of being perpendicular.
As used herein, the term “set” can refer to multiple features or a singular feature with multiple parts. For example, when referring to a set of protrusions, the set of protrusions can be considered as one protrusion with multiple portions, or the set of protrusions can be considered as multiple, distinct protrusions. Thus, a monolithically constructed item can include a set of protrusions. Such a “set” may include multiple portions and/or components that are either continuous or discontinuous from each other. Moreover, a “set” can also be formed from multiple components that are produced separately and are later joined together (e.g., via a weld, an adhesive, or any suitable method).
The devices and methods described herein are configured to stabilize devices and/or components of devices that are directly or indirectly inserted in a patient. Such devices are generally referred to herein as vascular access devices (VADs). Non-limiting examples of a VAD can include intravenous (IV) access devices such as peripheral intravenous catheters (PIV), peripheral intravenous central catheters (PICCs or PIC lines), midline catheters, extended dwell catheters (EDCs), etc. In other embodiments, a VAD can be an intra-arterial access device such as an arterial line, and/or the like. While reference to use with specific access devices is made herein, it should be understood that such reference is presented by way of example and not limitation.
As used herein, the term “catheter” describes an element configured to define a passageway such as a cannula, a tube, or other lumen-defining structure. In some instances, a catheter can be used for moving a bodily fluid from a first location to a second location (e.g., a fluid passageway to move a bodily fluid out of the body). While cannulas can be configured to receive a trocar, a guide wire, or an introducer to deliver the cannula to a volume inside the body of a patient, the catheters and/or cannulas referred to herein need not include or receive a trocar, guide wire, or introducer and can be positioned and/or inserted into, for example, the vasculature of a patient using any suitable method.
As used in this specification, the term “extension set” generally refers to a device or adapter that is coupled to a hub of a VAD such as a peripheral IV catheter or the like. The “extension sets” can be any suitable configuration. For example, in some embodiments, an extension set can be a single port or a multi-port adapter. As a specific example, an extension set can be and/or can refer to a “Y-shaped” dual port extension. In other embodiments, an extension set can be and/or can refer to a “T-shaped” dual port extension set.
In general, some known extension sets are configured to couple between a hub of a VAD and/or any suitable medical device and can allow one or more objects, devices, medicaments, fluids, etc. to access a portion of the body of a patient (e.g., via the VAD). More particularly, in some instances, an extension set can be coupled to an indwelling access device (e.g., a PIV or the like) and can facilitate the transfer and/or collection of one of more fluids. In some instances, the fluid can be a bodily fluid including, but not limited to, blood, cerebrospinal fluid, urine, bile, lymph, saliva, synovial fluid, serous fluid, pleural fluid, amniotic fluid, mucus, vitreous, air, and the like, or any combination thereof.
In some embodiments, any of the extension sets described herein can be a commercially available extension set. That is to say, in some embodiments, and of the stabilization devices described herein can be configured for use with a commercially available extension set. In other embodiments, any of the stabilization devices described herein can be configured for use with a custom extension set and/or an extension set configured for specific use with the stabilizer devices described herein. Accordingly, it should be understood, that the term “extension set” is provided by way of example only and not limitation.
As used in this specification, the words “proximal” and “distal” refer to the direction closer to and away from, respectively, a user who would place the device into contact with a patient. Thus, for example, the end of a device first touching the body of the patient would be the distal end, while the opposite end of the device (e.g., the end of the device being manipulated by the user) would be the proximal end of the device. Moreover, the terms “proximal” and “distal” when referring to a position of a construct or the like can be used to describe, for example, a relative position the construct so described. For example, a first portion of a device can be said to be in a distal position relative to second portion of the device when the position of the first portion of the device is further from the user of the device than the position of the second portion of the device.
The stabilization device 100 can be any suitable shape, size, and/or configuration. As shown in
The base surface 108 can be any suitable shape and/or configuration. For example, the base surface 108 can have a contour and/or shape that is generally concave. In some embodiments, the concave contour and/or shape can be based at least in part on a curvature and/or shape of a portion of the patient's anatomy. For example, in some embodiments, the base surface 108 can have a contour and/or shape that is based at least in part on a general contour and/or curvature of a patient's hand or forearm (or other suitable IV insertion site). In some embodiments, forming the contour and/or shape of the base surface 108 to be similar to and/or at least partially based on the curvature of an IV insertion site of the patient can, for example, increase a surface area of the base surface 108 that is in contact with the skin of the patient, which in turn, can increase the stability of the stabilization device 100 when secured to the skin of the patient, as described in further detail herein.
As shown in
The stabilization device 100 is configured to be placed in a position along the skin of the patient such that the recess 110 is aligned with and/or otherwise disposed over a vein of the patient. In some instances, the stabilization device 100 can be placed on the skin of the patient at or near an insertion site (also referred to as a “target location”) of, for example, an IV catheter. More specifically, the stabilization device 100 is configured to be positioned on the skin of the patient such that the recess 110 is disposed over the vein in which the VAD (e.g., the indwelling IV catheter, arterial catheter, or the like) is disposed. In some instances, such an arrangement can reduce an amount of force exerted by the base surface 108 on the vein, which might otherwise result in a reduced flow rate through at least a portion of the vein. For example, in embodiments in which the recess 110 is spaced apart from the skin of the patient, the stabilization device 100 does not (or substantially does not) exert a force on the vein in which the VAD is disposed. In other embodiments (e.g., when the recess 110 is in contact with the skin of the patient), a force exerted on by the recess 110 on the vein in which the VAD is disposed can be less than a force exerted by other portions of the base surface 108 (e.g., non-recess portions) on or near an area of the patient surrounding the vein.
The coupling surface 112 of the stabilization device 100 can be any suitable shape, size, and/or configuration. In some embodiments, the coupling surface 112 can form a contour or shape that is at least partially based on a shape of a vascular access device (VAD) 150 (or a hub thereof) and/or a device coupled to a VAD (e.g., an extension set or the like). In some embodiments, the coupling surface 112 can be configured to contact and/or engage an outer surface of the VAD 150 to form and/or define a friction fit therebetween. That is to say, the coupling surface 112 can have a size and/or shape that is slightly undersized relative to the VAD 150 to form a friction fit, press fit, interference fit, etc. when the VAD 150 is in contact with the coupling surface 112.
In some embodiments, the shape and/or contour of the coupling surface 112 can be configured to dispose the VAD 150 at a predetermined, predefined, and/or otherwise desired angle relative to the skin of the patient at or near the insertion site of the VAD 150. For example, in some embodiments, the coupling surface 112 can be angled such that a height of the coupling surface 112 at or near the proximal end portion 102 is greater than a height of the coupling surface 112 at or near the distal end portion 106. In some embodiments, the coupling surface 112 of the stabilization device 100 can be arranged to secure the VAD 150 at any suitable angle based at least in part on an angle of insertion of, for example, the VAD 150 or a catheter thereof. For example, in some embodiments, the coupling surface 112 can be configured to dispose the V AD 150 at an angle that can minimize a risk or likelihood of the VAD 150 (e.g., a catheter of the VAD 150) becoming kinked.
As described above, the stabilization device 100 can be used to secure, for example, a device coupled to a vascular access device. By way of example, in some embodiments, the stabilization device 100 can be configured to couple to and/or secure an IV extension set, which in turn is coupled to an indwelling or placed intravenous catheter. Although not shown in
As described above, the stabilization device 100 is configured to secure and/or stabilize the VAD 150 to, for example, the skin of a patient. For example, in some instances, an IV catheter (e.g., the VAD 150) can be inserted into the hand of a patient such that (1) a portion of the IV catheter is disposed within a vein and (2) a hub of the IV catheter is disposed outside of the patient. In some instances, an extension set (e.g., a T-adapter, Y-adapter, and/or the like) can be coupled to the hub of the IV catheter. With the extension set coupled to the IV hub, a user (e.g., a doctor, nurse, technician, physician, surgeon, and/or other medical professional) can manipulate the stabilization device 100 by placing a portion of the extension set (e.g., represented in
Once the stabilization device 100 is coupled to the extension set, the stabilization device 100 can be positioned on the skin of the patient (e.g., at or near the insertion site). In this example, the IV catheter is inserted into the hand of the patient and thus, the stabilization device 100 is position relative to the hand of the patient. Thus, the base surface 108 of the stabilization device 100 can be placed in contact with the skin of the patient at or near the insertion site (e.g., the site at which the VAD 150 or IV catheter enters the patient). In some instances, the stabilization device 100 can be adjusted and/or positioned such that the recess 110 is aligned with and/or otherwise disposed about or over the vein in which the IV catheter is disposed, as described above.
Having coupled the stabilization device 100 to the extension set and having placed the stabilization device 100 in the desired position at or near the insertion site, the user can secure the stabilization device 100 to the patient. In some embodiments, the user can secure the stabilization device 100 via medical tape or the like. For example, a user can remove a strip of medical tape from a roll of medical tape (e.g., a first strip of medical tape) and can apply the strip of medical tape to the proximal surface 104 of the stabilization device 100 (not shown in
In some instances, the user can remove a second strip of medical tape (not shown in
Although the first strip of medical tape and the second strip of tape are described as being applied in a specific order, it should be understood that the strips of medical tape can be applied to the stabilization device 100 and the VAD 150 in any suitable order. For example, in some instances, the user can apply the second strip of medical tape transversely across the portion of the stabilization device 100 and the VAD 150 (as described above) and then can apply the first strip of medical tape to the proximal surface 104 of the stabilization device 100 (as described above). Thus, in such instances, a portion of the first strip of medical tape overlaps a portion of the second strip of medical tape.
Securing the stabilization device 100 to the skin of the patient (e.g., via the medical tape) results in the stabilization device 100 and/or the medical tape securing, stabilizing, and/or substantially immobilizing the VAD 150 relative to the patient. That is to say, the arrangement of the stabilization device 100 is such that securing the stabilization device 100 and the VAD 150 to the skin of the patient can reduce and/or substantially prevent movement of the VAD 150 or at least an IV catheter thereof relative to the vein in which the IV catheter is at least partially disposed, as described in further detail herein with respect to a specific embodiment. Moreover, the arrangement of the recess 110 along the base surface 108 can reduce and/or can substantially eliminate a force otherwise exerted on the vein in which the VAD 150 (e.g., IV catheter or the like) is disposed.
The stabilization device 200 can be any suitable shape, size, and/or configuration. For example, in some embodiments, the stabilization device 200 can have a size and/or shape that is based at least in part on a size and/or shape of the VAD to be stabilized. In some embodiments, the size and/or shape of the stabilization device 200 can facilitate ease of use, for example, by simplifying a process of securing the stabilization device 200 to the skin of a patient. In some embodiments, the size and/or shape of the stabilization device 200 can increase ergonomics, grip, and/or the like. For example, in some embodiments, the stabilization device 200 and/or a portion thereof can allow a user maintain a secure grip on the stabilization device 200 as the user couples (or decouples) one or more devices to a VAD, an extension set, and/or any other suitable device being stabilized. In some instances, maintaining a secure grip during such a coupling or decoupling process can limit a force exerted on the stabilization device 200 that may otherwise be sufficient to move the stabilization device 200 relative to a target location on the patient (e.g., an IV catheter insertion site). In other words, the size and/or shape of the stabilization device 200 can allow it to stabilize, secure, and/or substantially immobilize a VAD coupled thereto as the user couples or decouples a device (e.g., a fluid transfer device or the like) to the VAD.
As shown in
The proximal end portion 202 has a proximal surface 204 that has a predetermined and/or desired shape. For example, the proximal surface 204 can be angled, tapered, flared, curved, rounded, and/or the like. In the embodiment shown in
The base surface 208 can be any suitable shape and/or configuration. For example, as shown in
As shown in
The stabilization device 200 is configured to be placed in a position along the skin of the patient such that the recess 210 is aligned with and/or otherwise disposed over the vein in which the IV catheter 250 is disposed. In some embodiments, when the base surface 208 of the stabilization device 200 is placed in contact with the skin of the patient, the recess 210 can be spaced apart from the skin of the patient (e.g., not in contact with the skin of the patient). In other embodiments, the base surface 208 including the recess 210 can be in contact with a portion of the skin of the patient. In some embodiments, the recess 210 can have a height (or depth) and a width that are each larger than a diameter of the vein in which the IV catheter 250 is to be disposed. In other words, a size and/or shape of the recess 210 can be based at least in part on a size and/or shape of a vein over which the stabilization device 200 is disposed. For example, in some embodiments, the recess 210 can have a height or depth that is approximately 0.5 millimeters (mm) to approximately 3.0 mm and a width that is approximately 5.0 mm to approximately 40.0 mm. As one example, a recess 210 can have a height or depth that is approximately 2.0 mm and a width that is approximately 20 mm.
While the recess 210 is particularly shown in, for example,
In some embodiments, forming and/or defining the recess 210 to be larger (e.g., in height and/or width) than the vein in which the IV catheter 250 is disposed can, for example, reduce an amount of force that would otherwise be exerted by the base surface 208 on the vein. In some instances, such a force exerted by the base surface 208 on the vein may be sufficient to reduce a flow of blood within the vein. In some specific instances, such a reduction in flow may negatively impact the ability to withdraw blood from the vein and/or may impede the delivery of fluids into the vein. Accordingly, forming the recess 210 in the base surface 208 is such that the stabilization device 200 does not (or substantially does not) exert a force on the vein in which the IV catheter 250 is disposed, thereby allowing the stabilization device 200 to secure and stabilize the IV catheter 250 without substantially impeding a flow of fluid through the vein.
While the recess 210 is described above as being configured to reduce and/or substantially remove a force exerted on the vein in which the IV catheter 250 is disposed, in some embodiments, the recess 210 can allow for movement and/or reconfiguration of a portion of the patient while continuing to provide stabilization to or for the IV catheter 250. For example, in some embodiments, an IV catheter (e.g., the IV catheter 250) can be inserted into a patient's cephalic or basilic vein and a stabilization device 200 (e.g., the stabilization device 200) can be secured to the patient's antecubital fossa region. In some instances, bending of the patient's arm (e.g., at the elbow) can result in a change in tension, stress, and/or strain of the skin both in a circumferential direction and an axial direction along the patient's arm. In some instances, such a change in tension or the like can result in a bunching or bulging of skin at or near the antecubital fossa region. In some instances, such a bunching or bulging of skin can result in undesired lifting or movement of a stabilization device relative to an IV insertion site, which in turn, can result in undesired movement, bending, kinking, etc. of the IV catheter disposed in the vein.
In some embodiments, however, the arrangement of the recess 210 of the stabilization device 200 can allow at least a portion of the skin to bunch or bulge in a space defined by the recess 210, thereby at least partially filling the void of the recess 210 and reducing and/or substantially preventing undesired lifting or movement of the stabilization device 200. In other words, in some instances, the arrangement of the stabilization device 200 can be such that the stabilization device 200 stabilizes, secures, and/or substantially immobilizes the IV catheter 250 despite at least some movement of the patient. Moreover, in some embodiments, the recess 210 can extend along the width of the stabilization device 200 such that only the edges of the base surface 208 and/or only protrusions extending from the base surface 208 are in contact with the skin. In such embodiments, this arrangement can allow the skin to shift and stretch axially underneath and to either side of the stabilization device 200 as shear forces are applied by movement of the skin, thereby reducing the amount of force that can otherwise result in lateral movement of the stabilization device 200 relative to the insertion site and/or target location.
The coupling surface 212 of the stabilization device 200 can be any suitable shape, size, and/or configuration. In the embodiment shown in
In the embodiment shown in
The one or more side channels 216 of the stabilization device 200 can be any suitable shape, size, and/or configuration. In the embodiment shown in
In some embodiments, the arrangement of the coupling surface 212 and the extension set 260 can be such that the extension set 260 is placed in contact with the coupling surface 212 and rotated into a position in which the side port 263 is disposed in one of the side channels 216. In some embodiments, a portion of the coupling surface 212 that forms and/or defines the side channels 212 can form a snap or press fit with at least a portion of the side port 263 of the extension set 260. Moreover, in use, the side port 263 of the extension set 260 is typically coupled to a flexible tubing 265 (see e.g.,
In some embodiments, the shape and/or contour of the coupling surface 212 can be configured to place and/or maintain a VAD (e.g., the IV catheter 250) at a predetermined, predefined, and/or otherwise desired angle relative to the skin of the patient at or near the insertion site of the IV catheter 250 (or target location). For example, in some embodiments, the coupling surface 212 can be angled such that a height of the coupling surface 212 at or near the proximal end portion 202 is greater than a height of the coupling surface 212 at or near the distal end portion 206. In some embodiments, the coupling surface 212 can be configured to receive, couple to, and/or secure the IV catheter 250 at an angle between, for example, about 3° and about 15° relative to the skin of the patient at the insertion site. Specifically, in some embodiments, the coupling surface 212 can be configured to receive, couple to, and/or secure the IV catheter 250 at an angle of about 10°, about 8°, about 6°, or less. In some embodiments, the coupling surface 212 of the stabilization device 200 can be arranged to secure the IV catheter 250 at any suitable angle based at least in part on an angle of insertion of, for example, the IV catheter. For example, in some embodiments, the coupling surface 212 can be configured to place and/or maintain the IV catheter 250 at an angle that can minimize a risk or likelihood of the IV catheter 250 becoming kinked (e.g., at the IV catheter insertion site or skin entry).
In some embodiments, the stabilization device 200 can be configured to secure the IV catheter 250 at an angle that is based at least in part on an IV insertion site. For example, in some embodiments, a stabilization device can be configured to secure an IV catheter at a first angle when the IV catheter is inserted into, for example, the antecubital fossa and a second angle, different from the first angle, when the IV catheter is inserted into, for example, the hand. In such embodiments, the stabilization device 200 can include an indicator and/or can have a color or the like configured provide an indication to a user associated with the intended use or intended insertion site.
As shown in
With the extension set 260 coupled to the IV hub, a user (e.g., a doctor, nurse, technician, physician, surgeon, and/or other medical professional) can manipulate the stabilization device 200 by placing a portion of the extension set 260 in contact with the coupling surface 212 of the stabilization device 200. As described above, the coupling surface 212 can be configured to form a friction fit and/or the like with the portion of the extension set 260 to couple the extension set 260 to the stabilization device 200. As shown, for example, in
Once the stabilization device 200 is coupled to the extension set 260, the stabilization device 200 can be positioned on the skin of the patient (e.g., at or near the insertion site or target location). In this example, the IV catheter 250 is inserted into the hand of the patient and thus, the stabilization device 200 is positioned relative to the hand of the patient. Thus, the base surface 208 of the stabilization device 200 can be placed in contact with the skin of the patient at or near the insertion site of the IV catheter 250 and/or otherwise at or near a target location of the patient. As described above, the stabilization device 200 can be adjusted and/or positioned such that the recess 210 is aligned with and/or otherwise disposed about or over the vein in which the IV catheter 250 is disposed. In this manner, securing the stabilization device 200 to the skin of the patient does not result in the base surface 208 exerting a force on the vein that may otherwise be sufficient to occlude and/or restrict flow through the vein.
Having coupled the stabilization device 200 to the extension set 260 and having placed the stabilization device 200 in the desired position at or near the insertion site (e.g., such that the recess 210 is aligned with or disposed over the vein in which the IV catheter 250 is disposed), the user can secure the stabilization device 200 to the patient. In some embodiments, the user can secure the stabilization device 200 via medical tape or the like, as shown, for example, in
As described above, the proximal surface 204 can have a shape, size, and/or configuration that facilitates the securement of the stabilization device 200. For example, in some embodiments, the proximal surface 204 can be angled and/or can have a relatively curved contour or the like such that when the user applies the first strip of medical tape 232 to the proximal surface 204, the tape curves bends, conforms, and/or otherwise forms a shape and/or follows a path that is at least partially based on the shape of the proximal surface 204. As shown in
After securing the first strip of medical tape 232, the user can remove a second strip of medical tape 234 from the roll of medical tape and can apply the second strip of medical tape 234 transversely across a portion of the stabilization device 200 and the IV catheter 250, as indicated by the arrows BB in
As described above, securing the stabilization device 200 to the skin of the patient (e.g., via the strips of medical tape 232 and 234) results in the stabilization device 200 and/or the medical tape securing, stabilizing, and/or substantially immobilizing the IV catheter 250 relative to the patient. That is to say, the arrangement of the stabilization device 200 is such that securing the stabilization device 200 and the IV catheter 250 to the skin of the patient can reduce and/or substantially prevent movement of the IV catheter 250 or at least an IV catheter thereof relative to the vein in which the IV catheter is at least partially disposed, as described in further detail herein with respect to a specific embodiment. Moreover, the arrangement of the recess 210 along the base surface 208 is such that securing and/or adhering the stabilization device 200 to the skin of the patient does not exert a force on the vein in which the IV catheter 250 is disposed, thereby reducing and/or substantially eliminating any obstruction and/or restriction otherwise resulting from such a force.
While the stabilization device 200 is described above with reference to
The stabilization device 300 can be any suitable shape, size, and/or configuration. For example, in some embodiments, the stabilization device 300 can have a size and/or shape that is based at least in part on a size and/or shape of the VAD to be stabilized. In some embodiments, the size and/or shape of the stabilization device 300 can facilitate ease of use, for example, by simplifying a process of securing the stabilization device 300 to the VAD, the device or adapter coupled to the VAD, and/or the skin of a patient. In some embodiments, the size and/or shape of the stabilization device 300 can increase ergonomics, grip, and/or the like. For example, in some embodiments, the stabilization device 300 and/or a portion thereof can allow a user maintain a secure grip on the stabilization device 300 as the user couples (or decouples) one or more devices to a VAD, an extension set, and/or any other suitable device being stabilized, as described above with reference to the stabilization device 200. In some embodiments, aspects and/or portions of the stabilization device 300 can be substantially similar to corresponding aspects and/or portions of the stabilization device 200. Accordingly, such aspects and/or portions of the stabilization device 300 are not described in further detail herein.
As shown in
The proximal end portion 302 has a proximal surface 304 that has a predetermined and/or desired shape. For example, the proximal surface 304 can be angled, tapered, flared, curved, rounded, and/or the like (see e.g.,
The base surface 308 can be any suitable shape and/or configuration. For example, as shown in
As shown in
As described above with reference to the stabilization device 200, the stabilization device 300 is configured to be placed in a position at or on a target location (e.g., along the skin of the patient at or near an IV insertion site) such that the recess 310 is aligned with and/or otherwise disposed over the vein in which the IV catheter 350 is disposed. In some embodiments, when the base surface 308 of the stabilization device 300 is placed in contact with the skin of the patient, the recess 310 can be spaced apart from the skin of the patient (e.g., not in contact with the skin of the patient). In some embodiments, the recess 310 can have a height (or depth) and a width that are each larger than a diameter of the vein in which the IV catheter 350 is to be disposed. In other words, a size and/or shape of the recess 310 can be based at least in part on a size and/or shape of a vein over which the stabilization device 300 is disposed. As such, the recess 310 can have a height and/or width that is sufficiently large to allow the recess 310 to be disposed over and/or above or about a vein that can vary in size, shape, and/or arrangement. Moreover, forming and/or defining the recess 310 to be larger (e.g., in height and/or width) than the vein in which the IV catheter 350 is disposed can, for example, reduce an amount of force that would otherwise be exerted by the base surface 308 on the vein and/or can allow for movement and/or reconfiguration of a portion of the patient while continuing to provide stabilization to or for the IV catheter 350, as described in detail above with reference to the stabilization device 200.
The coupling surface 312 of the stabilization device 300 can be any suitable shape, size, and/or configuration. In the embodiment shown in
In some embodiments, the coupling surface 312 can be configured to receive and/or couple to a T-shaped adapter or connector (e.g., the extension set 360), which in turn is coupled to a VAD (e.g., the IV catheter 350). As such, the stabilization device 300 can be configured to stabilize, support, and/or secure the VAD or IV catheter 350 when the coupling surface 312 is placed in contact with the T-shaped adapter, connector, and/or extension set 360. In some embodiments, the shape and/or contour of the coupling surface 312 can be configured to place and/or maintain a VAD (e.g., the IV catheter 350) at a predetermined, predefined, and/or otherwise desired angle relative to the skin of the patient at or near the insertion site of the IV catheter 350 (or target location). For example, in some embodiments, the coupling surface 312 can be angled such that a height of the coupling surface 312 at or near the proximal end portion 302 is greater than a height of the coupling surface 312 at or near the distal end portion 306. In some embodiments, the coupling surface 312 can be configured to receive, couple to, and/or secure the IV catheter 350 at an angle between, for example, about 3° and about 15° relative to the skin of the patient at or near the insertion site. In some embodiments, the coupling surface 312 of the stabilization device 300 can be arranged to secure the IV catheter 350 at any suitable angle based at least in part on an angle of insertion of, for example, the IV catheter 350 and/or the insertion site of the patient, as described in detail above with reference to the stabilization device 200.
As shown, for example, in
The one or more side channels 316 of the stabilization device 300 can be any suitable shape, size, and/or configuration. In the embodiment shown in
In some embodiments, the arrangement of the coupling surface 312 and the extension set 360 can be such that the extension set 360 is placed in contact with the coupling surface 312 and rotated into a position in which the side port 363 is disposed in one of the side channels 316. In some embodiments, a portion of the coupling surface 312 that forms and/or defines the side channels 312 can form a snap or press fit with at least a portion of the side port 363 of the extension set 360. Moreover, in use, the side port 363 of the extension set 360 is typically coupled to a flexible tubing 365 (see e.g.,
In some embodiments, the one or more protrusions 318 of the coupling surface 312 can be arranged and/or configured to ensure the stabilization device 300 is in a desired orientation and/or is facing a desired direction when the coupling surface 312 is placed in contact with the extension set 360. For example, as shown in
In some embodiments, the protrusions 318 can be configured to selectively engage a portion of the extension set 360 such that the coupling surface 312 is placed in a desired position and/or orientation relative to the extension set 360. For example, in some embodiments, the arrangement of the protrusions 318 can be such that when the distal end portion 306 of the stabilization device 300 is aligned with or placed in contact with the distal locking mechanism 362, the side port 363 of the extension set 360 is aligned with the side channels 316. More specifically, when the coupling surface 312 is placed in contact with the extension set 360 such that a portion of the distal locking mechanism 362 is disposed in and/or aligned with the distal notch 314 defined by the coupling surface 312, the side port 363 of the extension set 360 is aligned with and capable of being disposed in one of the side channels 316, as shown in
As described above, the arrangement of the protrusions 318 can allow and/or can be configured to allow the coupling surface 312 to be placed in contact with and/or coupled to the extension set 360 when the stabilization device 300 is in a desired orientation relative to the extension set. Conversely, the arrangement of the protrusions 318 can be such that if the stabilization device 300 is placed in an undesired orientation relative to the extension set 360, the contact between the coupling surface 312 and the extension set 360 can be limited and/or a coupling therebetween can be limited and/or prevented. For example, in instances in which the distal end portion 306 of the stabilization device 300 and the distal locking mechanism 362 are not aligned the protrusions 318 can selectively engage a portion of the extension set 360, which in turn, results in the side port 363 of the extension set 360 being misaligned relative to the side channels 316.
In some embodiments, the misalignment between the side port 363 and the side channels 316 can limit and/or substantially prevent the coupling surface 312 from being placed in contact with and/or being coupled to the extension set 360, which can provide an indication to a user that the stabilization device 300 is in an undesirable orientation relative to the extension set 360 (and/or vice versa). For example, in some instances, the protrusions 318 can selectively engage a portion of the extension set 360 to misalign the side port 363 relative to the side channels 316 when the stabilization device 300 and the extension set 360 are placed in opposite directions and/or orientations. More particularly, the protrusions 318 can selectively engage a portion of the extension set 360 to misalign the side port 363 relative to the side channels 316 when the coupling surface 312 of the stabilization device 300 is at least partially placed in contact with the extension set 360 such that the proximal locking mechanism 361 of the extension set 360 is aligned with and/or at least partially disposed in the distal notch 314 defined by the coupling surface 312. Said another way, when the proximal locking mechanism 361 of the extension set 360 is disposed in and/or aligned with the distal notch 314 defined by the coupling surface 312, a position of the side port 363 along the longitudinal axis A of the extension set 360 is misaligned relative to a position of the side channels 316 along the longitudinal centerline C of the stabilization device 300, which in turn, can limit and/or substantially prevent the side port 363 from being disposed in one of the side channels 316. Put simply, in some embodiments, the protrusions 318 can limit and/or substantially prevent the stabilization device 300 from being placed in a desired contact with or coupled to the extension set 360 while the stabilization device 300 is in a backwards orientation relative to the extension set 360.
As described above with reference to the stabilization device 200, the stabilization device 300 is configured to secure and/or stabilize the IV catheter 350 relative to, for example, a target location of a patient. For example, in some instances, the IV catheter 350 can be inserted into the hand of a patient (e.g., at or along a target location) such that (1) a portion of the IV catheter 350 is disposed within a vein and (2) a hub of the IV catheter 350 is disposed outside of the patient. In some instances, the extension set 360 (e.g., the T-adapter) can be physically and fluidically coupled to the hub of the IV catheter 350.
With the extension set 360 coupled to the IV hub, a user (e.g., a doctor, nurse, technician, physician, surgeon, and/or other medical professional) can manipulate the stabilization device 300 by placing a portion of the extension set 360 in contact with the coupling surface 312 of the stabilization device 300. As described above, the coupling surface 312 can be configured to form a friction fit and/or the like with the portion of the extension set 360 to couple the extension set 360 to the stabilization device 300. Moreover, the arrangement of the protrusions 318 can be configured to selectively engage the extension set 360 such that a user can visually inspect whether the stabilization device 300 and the extension set 360 are placed in a desired orientation relative each other, as described in detail above. Accordingly, the stabilization device 300 can be placed in contact with and/or coupled to the extension set 360 as described in detail above and shown in, for example,
Once the stabilization device 300 is coupled to the extension set 360, the stabilization device 300 can be positioned on the skin of the patient (e.g., at or near the insertion site or target location). In this example, the IV catheter 350 is inserted into the hand of the patient and thus, the stabilization device 300 is positioned relative to the hand of the patient. Thus, the base surface 308 of the stabilization device 300 can be placed in contact with the skin of the patient at or near the insertion site of the IV catheter 350 and/or otherwise at or near a target location of the patient. As described above, the stabilization device 300 can be adjusted and/or positioned such that the recess 310 is aligned with and/or otherwise disposed about or over the vein in which the IV catheter 350 is disposed. In this manner, securing the stabilization device 300 to the skin of the patient does not result in the base surface 308 exerting a force on the vein that may otherwise be sufficient to occlude and/or restrict flow through the vein.
Having coupled the stabilization device 300 to the extension set 360 and having placed the stabilization device 300 in the desired position at or near the insertion site (e.g., such that the recess 310 is aligned with or disposed over the vein in which the IV catheter 350 is disposed), the user can secure the stabilization device 300 to the patient. For example, although not shown in
As described above, securing the stabilization device 300 to the skin of the patient (e.g., via the strips of medical tape 332 and 334) results in the stabilization device 300 and/or the medical tape securing, stabilizing, and/or substantially immobilizing the IV catheter 350 relative to the patient. That is to say, the arrangement of the stabilization device 300 is such that securing the stabilization device 300 and the IV catheter 350 to the skin of the patient can reduce and/or substantially prevent movement of the IV catheter 350 or at least an IV catheter thereof relative to the vein in which the IV catheter is at least partially disposed, as described in further detail herein with respect to a specific embodiment. Moreover, the arrangement of the recess 310 along the base surface 308 is such that securing and/or adhering the stabilization device 300 to the skin of the patient does not exert a force on the vein in which the IV catheter 350 is disposed, thereby reducing and/or substantially eliminating any obstruction and/or restriction otherwise resulting from such a force.
As shown in
In some embodiments, the coupling surface can include one or more features, protrusions, members, etc. configured to selectively engage a portion of the VAD or adapter if, for example, the stabilization device, VAD, and/or adapter are in an undesirable orientation or the like, as described above with reference to the coupling surface 312. For example, in some embodiments, the coupling of the stabilization device to the VAD includes coupling the stabilization device to an extension set, aligning a longitudinal axis of the extension set with a longitudinal centerline of the stabilization device (e.g., such that the longitudinal axis and the longitudinal centerline are co-axial, parallel, and/or otherwise extending in a substantially similar direction), and placing the extension set in contact with the coupling surface of the stabilization device. As described above, when the stabilization device and/or the extension set are in a desired orientation and/or are otherwise facing in the same direction, the side port of the extension set can be aligned with and placed in contact with a side channel of the coupling surface. If, however, the stabilization and/or the extension set are not in a desired orientation and/or are otherwise facing in opposite directions, the features, protrusions, members, etc. of the coupling surface can engage a portion of the extension set, which in turn, can result in the side port of the extension set being misaligned relative to the side channel and thereby, substantially prevented from being placed in contact therewith (as described in detail above with reference to the stabilization device 300). In other embodiments, the coupling surface of the stabilization device need not include such a feature or the like.
After coupling the stabilization device to the VAD, the stabilization device is positioned on the skin of the patient (e.g., at a target location) such that a recessed portion formed by a base surface of the stabilization device is aligned with the vein, at 12. As described above with reference to the stabilization devices 100, 200, and/or 300, the recessed portion can be configured to reduce and/or substantially prevent the base surface from exerting an undesired force on the vein of the patient when the stabilization device is secured to the skin of the patient. Accordingly, the position of the stabilization device relative to the target location and/or an IV insertion site can be adjusted until the recessed portion is aligned with and/or disposed above or about the vein.
With the stabilization device in the desired position, a first strip of medical tape is applied to a proximal surface of the stabilization device such that each of a first end portion and a second end portion of the first strip of medical tape are in contact with the target location of the patient and are distal to a medial portion of the first strip of medical tape, at 13. As described above with reference to the stabilization device 200, the first strip of medical tape can be applied to the stabilization device such that a portion of the first strip overlays and/or is adhered to at least a portion of the proximal surface of the stabilization device. In some embodiments, the proximal surface of the stabilization device can have a size and/or shape that is configured to result in a bending or bowing of the first strip of medical tape when it is applied to the proximal surface (e.g., as described above with reference to
The method 10 includes applying a second strip of medical tape to a portion of the stabilization device such that the second strip of medical tape partially overlaps at least the first end portion and the second end portion of the first strip of medical tape, at 14. For example, as described above with reference to
In some embodiments, the arrangement of the first strip of medical tape and the second strip of medical tape can be such that a proximal locking mechanism of the extension set extends between and/or through a space, gap, and/or separation defined between, for example, the medial portion of the first strip of medical tape and the medial portion of the second strip of medical tape (see e.g.,
As described above, securing the stabilization device to the skin of the patient at, on, or near the target location (e.g., via the strips of medical tape) results in the stabilization device securing, stabilizing, and/or substantially immobilizing the IV catheter relative to the target location of the patient. That is to say, the arrangement of the stabilization device is such that securing the stabilization device and the IV catheter to the skin of the patient can reduce and/or substantially prevent movement of the IV catheter or at least an IV catheter thereof relative to the vein in which the IV catheter is at least partially disposed, as described in further detail herein with respect to a specific embodiment. Moreover, the arrangement of the recessed portion along the base surface is such that securing and/or adhering the stabilization device to the skin of the patient does not exert a force on the vein in which the IV catheter is disposed, thereby reducing and/or substantially eliminating any obstruction and/or restriction otherwise resulting from such a force.
