The present invention relates in general to a device for securing medical tubing, such as a Foley catheter, to a patient.
The use of medical tubing in various surgical and therapeutic treatments or during recovery is well known in the art. For example, urinary catheters, CVCs, hemodialysis catheters, suprapubic catheters, surgical drainage tubes, feeding tubes, chest tubes, nasogastric tubes, scopes, as well as electrical wires or cables connected to external or implanted electronic devices or sensors, are some of the various types of medical tubing that are employed by medical practitioners. With respect to urinary catheters, some of the more common types include Foley catheters, Coudé catheters, and Pezzer or mushroom catheters. With respect to urological procedures, catheterization often involves inserting a tube (urinary catheter) through the urethra into the bladder to remove urine. The bladder is sterile, so surgical asepsis must be used when performing this procedure. A urinary catheter is generally indicated when a person is unable to void naturally due to injury or a disease process, has had abdominal surgery, or is voiding overflow.
There are many different types of urinary catheters and each has a particular purpose. A Coudé catheter has a tapered tip that is designed for easy insertion when enlargement of the prostate is suspected. A Foley catheter has a balloon in its tip that is inflated after insertion so that it remains in the bladder. A Pezzer or Mushroom catheter has a triangular or knot-like tip and is used to drain urine from the renal pelvis; it can also be used for a suprapubic catheterization.
Simple urethral catheters are designed for in-and-out procedures. A three-way indwelling catheter has a balloon in its tip that is inflated after it is inserted and also has another tube or lumen that can be used for continuous bladder irrigation. A suprapubic catheter is surgically inserted through the abdominal wall above the symphysis and into the bladder to divert urine from the urethra.
Foley catheters typically include a soft, thin rubber tube with a balloon on one end. The catheter is threaded through the urinary duct (urethra) and into the bladder to drain urine from the bladder. A Foley catheter is typically used when normal urination is disrupted by an infection, a swollen prostate gland, bladder stones, or, sometimes, an injury. In very sick people, a catheter may be used to keep track of urine production.
A typical Foley catheter has a drainage lumen and an inflation lumen for inflating and deflating the balloon. The balloon is normally deflated until properly positioned in a patient's bladder by inserting the catheter through the urinary tract of the patient and advancing the catheter until the tip of the catheter reaches the patient's bladder. Although the catheter usually includes a siliconized outer coating, as provided by the manufacturer, healthcare providers often apply further lubricant, such as a water-based jelly. Once the catheter is properly positioned, the inflation lumen delivers fluid (e.g., saline solution) to inflate the balloon. Once-inflated, a valve, which is located at the inflation port, inhibits the flow of fluid from the inflation lumen and the balloon to keep the balloon inflated. The inflated balloon prevents the catheter from unintentionally dislodging from the bladder. The healthcare provider then connects the distal end of the drainage lumen (i.e., its effluent port) to a drainage tube leading to a collection container.
Once a Foley catheter, or other tubing, is inserted into the patient, the part of the tubing that is on the outside of the patient (extracorporeal tubing) is typically secured to the patient's body using medical tape. This is done to reduce the risk of accidentally pulling or dislodging the tubing by inadvertently wrapping it around a limb or bedrail or knocking it out of position. With respect to Foley catheters, the healthcare provider commonly places long pieces of tape across the distal end of the catheter in a crisscross pattern to secure the catheter distal end to the inner thigh of the patient.
Medical tape has proven to be an unsatisfactory and crude means of securing medical tubing to a patient. One problem is that medical tape can crush the tubing and impede fluid flow. Another problem is that medical tape does not provide any freedom of movement to the tubing with respect to the patient's body. Consequently, any movement in the tubing caused by the patient's movements may cause the tape to twist and peel away from the skin and to generally fail. Yet another problem is that medical tape often collects contaminants and dirt. Standard protocol therefore typically requires periodic tape changes in order to inhibit bacteria and germ growth at the securement site.
Frequent tape changes may, however, lead to another problem: excoriation of the patient's skin. In addition, valuable healthcare provider time is spent applying and reapplying the tape to secure the catheter. And healthcare providers often remove their gloves when taping because most find the taping procedure difficult and cumbersome when wearing gloves. Not only does this further lengthen the procedure, but it also subjects the healthcare provider to possible infection.
Thus, it is highly desirable to have a new and improved device and method for securing medical tubing to a patient that overcomes the problems associated with medical tape.
A medical tubing securement assembly includes a base having a disc, and a retaining adapter removably and rotatably attached to the disc. The retaining adapter includes a longitudinal passage for receiving a locking adapter. The locking adapter includes a longitudinal passage for receiving a medical tube. Once the tube is inserted into the locking adapter, the locking adapter may be rotated within the retaining adapter, around the tube, to secure the tube within the securement assembly.
Other features and advantages of the invention will appear hereinafter. The features of the invention described above can be used separately or together, or in various combinations of one or more of them. The invention resides as well in sub-combinations of the features described. Furthermore, many of the method steps described herein may be performed in a different order than that which is explicitly described.
In the drawings, wherein the same reference number indicates the same element throughout the several views:
Various embodiments of the invention will now be described. The following description provides specific details for a thorough understanding and enabling description of these embodiments. One skilled in the art will understand, however, that the invention may be practiced without many of these details. Additionally, some well-known structures or functions may not be shown or described in detail so as to avoid unnecessarily obscuring the relevant description of the various embodiments.
The terminology used in the description presented below is intended to be interpreted in its broadest reasonable manner, even though it is being used in conjunction with a detailed description of certain specific embodiments of the invention. Certain terms may even be emphasized below; however, any terminology intended to be interpreted in any restricted manner will be overtly and specifically defined as such in this detailed description section.
Where the context permits, singular or plural terms may also include the plural or singular term, respectively. Moreover, unless the word “or” is expressly limited to mean only a single item exclusive from the other items in a list of two or more items, then the use of “or” in such a list is to be interpreted as including (a) any single item in the list, (b) all of the items in the list, or (c) any combination of items in the list.
For ease of description, the present embodiments of the medical tubing securement assembly will be described in the context of securing an exemplary Foley catheter. The principles of the present invention, however, are not limited to Foley catheters. Indeed, it will be understood by one of skill in the art, in view of the present disclosure, that the medical tubing securement assembly disclosed herein can also be used to secure other types of medical tubing, including tubes for fluid communication and electrical wires.
The medical tubing securement assemblies disclosed herein may be adapted to retain other types of urinary catheters, including, but not limited to, CVCs, hemodialysis catheters, suprapubic catheters, surgical drainage tubes, feeding tubes, chest tubes, nasogastric tubes, scopes, as well as electrical wires or cables connected to external or implanted electronic devices or sensors. One skilled in the art may also find additional applications for the devices disclosed herein. Thus, the illustrations and descriptions of securement assemblies disclosed herein in connection with a Foley catheter are merely exemplary of one possible application of the device.
Referring now to the drawings,
As illustrated in
In one embodiment, the top surface of the base pad 100 may be secured to the bottom surface of the base plate 200 with a non-skin irritating adhesive. The bottom surface of the base plate 200 or the top surface of the base pad 100 may be coated with the non-skin irritating adhesive. The securement assembly 10 may then be secured to the patient's skin by removing the wax paper strips and adhering the bottom surface of the base pad 100 to the skin, or in any other suitable manner.
In another embodiment, as shown in
Alternatively, the base plate 200 can be sandwiched between the base pad 100 and a layer of double-sided medical tape secured to the bottom surface of the base plate 200. The double-sided medical tape may be coated with a non-skin irritating adhesive to secure the top surface of the tape to the bottom surface of the base plate 200, and the bottom surface of the tape to the patient's skin.
Turning to
The platform 210 optionally includes a central opening 215 over which a bridge 230 extends. The disc 220 rests atop the bridge 230. One or more raised pedestals (not shown) may optionally be included atop the platform to provide additional support to the retaining adapter 300 as it rotates atop the disc 220. The disc 220 may have any suitable diameter, preferably between 0.5 cm to 5.0 cm. In one embodiment, the disc has a diameter of approximately 1.8 cm. The disc 220 preferably has a substantially flat top surface and includes a protuberance 224 at its center, which forms a spindle. The protuberance 224 may be cone-shaped, round or hemispherical, bell-shaped, or have any other suitable configuration. A raised ring 226 optionally forms a lip or snap-ring at an outer rim of the disc 220. The retaining adapter 300 preferably snaps or otherwise fits onto the lip formed by the raised ring 226, as described below.
The platform 210, bridge 230, disc 220, protuberance 224, and ring 226 of the base plate 200 may optionally be a unibody construction made from a single mold. Alternatively, one or more of these components may be formed from one or more separate molds and connected to the other components via adhesive, welding, or via any other suitable manner. Each of the components of the medical securement assembly 10 may be made of any suitable material, such as a flexible plastic or elastomeric material.
Turning to
The distal edge of the distal sleeve 310 optionally forms a substantially backwards “C” shape. The distal edge preferably includes a recessed section 318 defined between a first raised section 312 and a second raised section 313. A protuberance or projection 314 preferably resides within the recessed section 318 for securing the locking adapter 370 into the locked position, as described below. The proximal sleeve 320 optionally includes a recessed section 350 or indentation on an inner surface thereof for accommodating a raised wedge 550 or elevated segment on the locking adapter 370, as described below.
The distal sleeve 310 may include one or more directional markers, such as an arrow 315 and a lock indicator 317. The arrow 315 preferably points in the distal direction toward the intended site of incision or insertion of the catheter. The lock indicator 317 indicates the position to which a lever 540 on the locking adapter 370 should be rotated to secure the Foley catheter 400 within the securement assembly 10, as described below. The distal sleeve 310 also preferably includes a retainer tab 316 that extends from the top side of the distal sleeve 310 toward the proximal sleeve 320. The distal sleeve 310 and the proximal sleeve 320 are preferably connected at their bottom portions via the bridge 360, leaving the remainder of the sleeves 310 and 320 disjoined.
Accordingly, a gap exists between the proximal sleeve 320 and the distal sleeve 310 that extends substantially perpendicularly to the longitudinal axis of the retaining adapter 300. The gap can accommodate, and provides a passageway for, a side branch of a medical tube, such as the inflation lumen 410 of the Foley catheter 400. The gap, in conjunction with the lateral opening 319, also provides an opening into which the Foley catheter may be inserted, as described below.
In one embodiment, the retaining adapter 300 is secured or attached to the base plate 200 in a manner allowing it to rotate or spin atop the disc 220. The retaining adapter 300 includes a front or distal support 330 with a first connection groove 331, and a rear or proximal support 335 with a second connection groove 332. The raised ring 226 on the disc 220 may be inserted into the first and second connection grooves 331 and 332 to provide a track on which the distal and proximal supports 330 and 335 slide or run. This connection between the retaining adapter 300 and the disc 220 allows the adapter 300 to rotate atop the disc 220. Alternatively, the retaining adapter 300 may be fixedly secured to the disc 220, and the disc 220 may be rotatable about the bridge 230 or the platform 210 of the base plate 200.
The retaining adapter 300 preferably includes a cavity or opening (not shown) on its bottom surface, approximately midway between the distal support 330 and the proximal support 335. The cavity mates with the protuberance 224 on the disc 220. The bottom surface of the retaining adapter 300 is preferably spaced apart from the top surface of the disc 220. The gap provided by this spacing reduces friction between the retaining adapter 300 and the disc 220 when the retaining adapter 300 is rotated, allowing for freer rotation of the retaining adapter 300 atop the disc 220.
The retaining adapter 300 is secured to the disc 220 via insertion of the raised ring 226 into the first and second connection grooves 331 and 332. Although the retaining adapter 300 is preferably removable, it cannot be removed from the disc 220 simply by pulling the retaining adapter 300 in an upward manner; the groove/ring connection prohibits such detachment. The retaining adapter 300, however, is preferably made of a flexible material that allows the bridge 360 of the retaining adapter 300 to flex or bend.
When the proximal and distal sleeves 320 and 310 of the retaining adapter 300 are squeezed toward each other, the bridge 360 flexes such that the proximal and distal sleeves 320 and 310 tilt inwardly toward each other, and the proximal and distal supports 335 and 330 are forced upward and away from each other. This upward and outward movement of the proximal and distal supports 335 and 330 frees the ring 226 from the proximal and distal connection grooves 332 and 331, consequently freeing the retaining adapter 300 from the disc 220. Thus, the retaining adapter 300 can be detached from the disc 220 by squeezing the proximal and distal sleeves 320 and 310 toward each other. The adapter 300 can be reattached to the disc 220 by positioning one of the connection grooves 331 and 332 over the ring 226 and snapping or otherwise forcing the other connection groove over the ring 226. The bend able bridge 360 returns to its original substantially level state unless a force causes it to bend out of its level state.
In one embodiment, as shown in
Turning to
The proximal sleeve 520 optionally includes a wedge 550 or other elevated segment on an outer surface thereof for providing an interference fit with an inner surface of the proximal sleeve 320 of the retaining adapter 300 (as is best shown in
The proximal sleeve 520 further preferably includes a raised outer rim 570 or edge that abuts a proximally outer surface of the proximal sleeve 320, as shown in
The opening 519 in the distal sleeve 510 is preferably wide enough to accommodate a medical tube, such as the Foley catheter 40, when the tube is squeezed through the opening 519 and into the space or tunnel formed by the inner surface of the distal sleeve 510. Alternatively, the opening 519 may be narrower than the medical tube, as long as the locking adapter 370 (and the retaining adapter 300) is made of a material flexible enough to allow the opening 519 to be enlarged by pushing the free opposing surfaces of the distal sleeve 510 away from each other to allow the medical tube to be squeezed through the opening 519. Once the medical tube is squeezed through the opening 519 the distal sleeve 510 returns to its original shape.
Similarly, the opening 521 in the proximal sleeve 520 is preferably wide enough that a medical tube, such as the Foley catheter 400, can be squeezed through the opening 521 and into the space or tunnel formed by the inner surface of the proximal sleeve 520. Alternatively, the opening 521 may be narrower than the medical tube, as long as the locking adapter 370 (and the retaining adapter 300) is made of a material that is flexible enough to allow the opening 521 to be enlarged by pushing the free opposing surfaces of the proximal sleeve 520 away from each other to allow the medical tube to be squeezed through the opening 521. Once the medical tube is squeezed through the opening 521 the proximal sleeve 520 returns to its original shape.
As illustrated in
The locking adapter 370 may then be moved in the distal direction until the raised outer rim 570 abuts against the proximally outer surface of the proximal sleeve 320, which prevents the locking adapter 370 from further distal movement. The lever 540 may then be manually pulled or forced distally beyond the first raised section 312 and rotated (clockwise in
In this open or unlocked position, a side edge of the lever 540 abuts an inner edge of the first raised section 312, such that the lever 540 is oriented in a substantially upward manner. In this position, the first opening 521 in the locking adapter 370 is substantially or perfectly aligned with the upper opening 321 in the retaining adapter 300, and the second opening 519 in the locking adapter 370 is substantially or perfectly aligned with the lateral opening 319 in the retaining adapter 300. The first opening 521 and the upper opening 321 preferably have substantially the same dimensions, as do the second opening 519 and the lateral opening 319. Accordingly, when the openings are aligned in the unlocked position, a medical tube, such as the Foley catheter 400, may be inserted through both layers of openings for securement within the securement assembly 10.
To insert the Foley catheter 400 into the securement assembly 10 in the unlocked position, a mid-region or other region of the primary tube 405 is inserted through the lateral opening 319 of the retaining adapter 300 and the corresponding second opening 519 of the locking adapter 370 (and through the neighboring lateral gap). The proximal end of the primary tube 405 is inserted through the upper opening 321 in the retaining adapter 300 and the corresponding first opening 521 in the locking adapter 370. In this position, the primary tube 405 passes through, and is reasonably secured within, the distal sleeve 510 and the proximal sleeve 520 of the locking adapter 370.
If the inflation lumen or tube 410 is not already aligned with the lock indicator 317, the inflation tube 410 is rotated (clockwise in
Once the Foley catheter 400 is in the working position, the locking adapter 370 is rotated (clockwise in
In the locked position, portions of the distal sleeve 510 and the bridge 560 of the locking adapter 370 block the lateral opening 319 and the neighboring lateral gap in the retaining adapter 300 so the Foley catheter 400 cannot slide laterally out of the securement assembly 10. Similarly, the portion of the proximal sleeve 520 of the locking adapter 370 including the wedge 550 blocks the upper opening 321 in the proximal sleeve 320 of the retaining adapter 370 so the Foley catheter 400 cannot slide out of the upper opening 321. As a result, the Foley catheter 400 (or other medical tube) is securely held within the securement assembly 10 when the securement assembly 10 is in the locked position.
To remove the Foley catheter 400 from the securement assembly 10, the lever 540 is rotated (counterclockwise in
The medical tubing securement assembly 10 may be packaged as a kit including the base pad 100, the base plate 200 (including the disc 220), the retaining adapter 300, the locking adapter 370, and instructions for use. In one embodiment, a separate disc may also be included in a kit that includes a variable angle medical tubing securement assembly, as described in U.S. Provisional Application Ser. No. 60/718,619. The kit may be contained in a hermetically sealed package that includes written instructions on the package, inside the package, or separate from the package.
The instructions provide a method for using the medical tubing securement assembly 10. First, the medical tubing, such as a Foley catheter, is introduced into the patient's body. A skin preparation solution can then be applied for enhanced adherence and skin protection, after which the base pad 100 is adhered to the patient's skin. The method described above for inserting the medical tubing into the securement assembly 10 is then performed. The retaining adapter 300 may be attached to the disc 220 on the base plate 200 before or after the medical tubing is secured in the securement assembly 10.
Specific details and examples of variable angle assemblies, base plates, discs, and so forth are described in U.S. Provisional Application Ser. No. 60/718,619. While specific embodiments of a securement assembly 10 have been described herein, any securement assembly in which one or more openings in a retaining adapter and a locking adapter are alignable with one another in an unlocked position, and in which one or both of the adapters are rotatable into a locked position wherein one or more of the openings are blocked, is contemplated by the present invention.
Thus, while several embodiments have been shown and described, various changes and substitutions may of course be made, without departing from the spirit and scope of the invention. The invention, therefore, should not be limited, except by any claims and their equivalents.
This application is a continuation of U.S. application patent Ser. No. 11/532,194, filed Sep. 15, 2006, entitled MEDICAL TUBING SECUREMENT ASSEMBLY AND METHODS OF USE, now U.S. Pat. No. 8,052,649, which claims priority under 35 U.S.C. §119(e) to U.S. Provisional Patent Application No. 60/718,619, filed Sep. 19, 2005, and U.S. Provisional Patent Application No. 60/758,359, filed Jan. 12, 2006, each of which is hereby incorporated by reference in its entirety.
