This invention relates to easily removable, non-irritating stretchable sleeve or chest wrap for protecting and securing a PICC line or chest catheter tubing and cap extending externally from the insertion point.
Intravenous or IV therapy involves administration of liquids directly into a patient's veins through an inserted catheter. Long-term, continuous IV therapy (for administrating chemotherapy regimens, frequent drawing of blood samples, antibiotic regimens, or tube feeding [parenteral nutrition]) is usually accomplished with a peripherally inserted central catheter line (or PICC line), or through a more central location with a central venous catheter or a Broviac catheter.
A PICC line is a soft, flexible tube, with one or more internal lumens. The PICC line is surgically inserted into a peripheral vein, often the arm, in a sterile procedure that must be undertaken by a trained medical professional. During insertion, the PICC line is drawn upward with an inserted guide wire until the tube is in, or proximate to, the superior vena cava of the heart. PICC lines are usually inserted 25 to 60 cm within a patient's peripheral vein.
A central venous catheter is a soft, flexible tube, with one or more internal lumens that has a larger diameter than a PICC line. A Broviac catheter is a central venous catheter with a smaller lumen for use with small children. The central venous catheter is placed directly into a large vein in the neck, chest, or groin.
PICC lines can remain in situ for extended periods of time, from days to a year. PICC lines and central venous catheters are more patient-friendly, because they necessitate only one tube insertion, rather than repeated ones.
Once the PICC line or the central venous catheter is inserted, the guide wire is removed and a small length of the PICC line or the central venous catheter remains external to the patient, extending outwards from the point of insertion. The external end of the PICC line or the central venous catheter is capped to prevent bacteria, viruses or contaminants from entering.
This small length of the PICC line or the central venous catheter often dangles, unsupported, near the point of insertion. There is a constant danger of pulling or otherwise interfering with the PICC line or the central venous catheter during normal daily activities or during sleep. Tape is generally used to secure the tubes while not in use. These tapes can lead to pain, inflammation, infections, and reduced drug efficacy. The problem in movement is especially pronounced in young children undergoing long-term therapy with a PICC line or a central venous catheter.
Thus, this small length of the PICC line or the central venous catheter, and the end cap, must be attached to the patient to prevent movement or dislodgment of the internal tubing. This movement or dislodgment may prevent the administered liquids from reaching the desired veins, or cause significant inflammation to the insertion point, air embolisms, arterial punctures, internal bruising, and blood clots. The PICC line or the central venous catheter external attachment must also protect the tubing from being pierced or otherwise punctured due to movement. A pierced or punctured PICC line or central venous catheter, would not only prevent administered liquids from reaching the desired veins, it may also allow bacteria or contaminants to enter, causing internal infections in the patient.
Previous solutions to prevent movement of the PICC line or the central venous catheter have included taping the external small length of the lines with various medical tapes. These tapes often leave adhesive residues that are irritating to the skin. These irritations can often lead patients to inadvertently scratch the insertion points, thereby moving the small length of the external PICC line or the central venous catheter. Some newer medical tapes reduce or virtually eliminate adhesive residue, but these tapes are not as strong and still irritate the skin surrounding the insertion point. Furthermore, this medical tape must often be partially removed to access the PICC line or the central venous catheter and then re-taped once the IV therapy is complete. This removal of the tape and re-taping to the skin can result in significant irritation. Moreover, when the end of the PICC line or the central venous catheter is taped visibly from the outside of the patient's clothing, it presents an unsightly and disturbing appearance that can produce mental distress.
Accordingly, there is a need for a protective sleeve to protect the PICC line or the central venous catheter insertion points. This sleeve needs to be easily attached to a patient's arm or body, secure the small length of the external PICC line or the central venous catheter, protect the tubing and cap from external contaminants, and allow easy access to the PICC line or the central venous catheter for administration of drugs or nutrients, and access for blood draws. This sleeve must also allow the patient freedom of movement and be comfortable enough to prevent skin irritation over long-term usage.

Advantages of the present invention will be apparent from the following detailed description of embodiments thereof, which description should be considered in conjunction with the accompanying drawings, in which:
While several variations of the present invention have been illustrated by way of example in particular embodiments, it is apparent that further embodiments could be developed within the spirit and scope of the present invention, or the inventive concept thereof. However, it is to be expressly understood that such modifications and adaptations are within the spirit and scope of the present invention, and are inclusive, but not limited to the following appended claims as set forth.
The sleeve 1 contains a lumen 8, or internal cavity that is substantially parallel with the longitudinal axis. The lumen 8 passes through the proximal end 2 to define a proximal opening 9 that is substantially perpendicular to the longitudinal axis, and further passes through the distal end 3 to define a distal opening 10 that is substantially perpendicular to the longitudinal axis. The proximal opening 9, the distal opening 10, and the lumen 8 are all configured for receiving and holding a patient's arm 11. In use, a patient places his or her arm 11 through the proximal opening 9, through the lumen 8 and out through the distal opening 10 to place the sleeve 1 over the PICC line insertion point 12 on the arm 11.
In one embodiment of the subject invention, the sleeve 1 may have a substantially equal diameter from the proximal end 2 to the distal end 3. In another embodiment of the subject invention, the sleeve 1 may have slightly taped diameter from the proximal end 2 to the distal end 3. This slightly tapered diameter embodiment may be used to accommodate an elbow or forearm that has a larger diameter than a wrist on the same arm.
In embodiments of the subject invention, the cross-sectional shape of the sleeve 1 may be substantially circular or substantially elliptical.
The sleeve 1 comprises is stretchable so as to allow the sleeve 1 to be easily slipped on and off a patient's arm 11. This stretchability should apply sufficient inward compression force such that the sleeve 1 should substantially conform to the anatomy of a patient's arm 11, such that compression force of the sleeve 1 does not substantially affect circulation in the limb, remains in place during treatment, remains in place while the patient sleeps, and remains in place if the patient moves or engages in normal activities. This compression force should be inward compression that is substantially equal over the internal surface 5 of the sleeve 1. The sleeve 1 comprises a stretchability that allows it to remain in place on the patient's arm and secure the PICC line 6 in place without any additional fasteners, such as hook and loop fasteners, buttons, clamps, brackets, buckles, magnets, snaps, tie straps, tape layers, or adhesives.
This sleeve 1 must also allow the patient freedom of movement in the covered arm 11. The sleeve 1 is designed for use with all ages and sizes and can be worn on either arm 11.
Once the PICC line is inserted, a small length of the PICC line 6 remains external to the patient, extending outwards from the point of insertion 12. The external end of the PICC line 6 is capped 7 to prevent bacteria, viruses or contaminants from entering the PICC line. As shown in
The end of the small length of the PICC line 6 contains a cap 7. This cap 7 must be periodically replaced, typically weekly, to reduce the risk of contamination. Replacing the cap 7 must also be a sterile procedure that is conducted with washed hands, sterile gloves, sterile clothing, and alcohol swaps in a sterile environment.
The insertion point 12 of the PICC line 6 may be covered with a traditional removable bandage 15. In this embodiment, this removable bandage 15 should only cover a very small portion of the external small length of the PICC line 6 that is proximate to the insertion point 12.
In one embodiment of the subject invention, the sleeve 1 may comprise a flexible substantially transparent or semi-transparent window (not shown) that traverses the external 4 and internal surfaces 5 of the sleeve 1. The sleeve 1 should be aligned over the patient's arm 11 such that the flexible substantially transparent or semi-transparent window is over the PICC line insertion point 12. In another embodiment of the subject invention, this substantially transparent window may be composed of a mesh or mesh-like material.
The sleeve 1 is designed to cover and protect both the arm 11 and external short length of the PICC line 6. The sleeve covers the PICC line insertion area 12 and protects it from clothing, rubbing, and other external influences.
The sleeve 1 comprises a slit opening 16 proximate to the PICC line insertion point 12. This slit opening 16 passes through the internal surface 5 to define an internal opening 17 that may be substantially perpendicular to the longitudinal axis and further passes through the external surface 4 to define an external opening 18 that may be substantially perpendicular to the longitudinal axis. The slit opening 16, the internal opening 17, and the external opening 18 are all configured for receiving and removably holding the external small length of the PICC line 6. In use, a patient moves the external small length of the PICC line 6 and the distal end cap 7 through the slit opening 16 onto the exterior surface 4 of the sleeve 1.
The sleeve 1 further comprises a substantially flat strap 19 on the external surface 4, distal from the slit opening 16. This strap 19 comprises a first end 20 and a second end 21 that are both attached to the external surface 4 of the sleeve 1. The strap 19 may be substantially rectangular or square in shape. The central portion of the strap 19 is unattached to the sleeve 1 to form a strap opening 22 that is configured for receiving and removably holding the external small length of the PICC line 6. This strap opening 22 may be substantially perpendicular to the longitudinal axis. In use, a patient moves the external small length of the PICC line 6 and the distal end cap 7, already passed through the slit opening 16, through the strap opening 22 underneath strap 19.
The sleeve 1 further comprises a substantially flat pocket 23, disposed on external surface 4 of the sleeve 1, distal from the strap 19. This pocket 23 comprises a pocket opening 24 that is substantially perpendicular to the longitudinal axis and is configured for receiving and removably holding the external small length of the PICC line 6 and the distal end cap 7. The cap 7 and the external small length of the PICC line 6 are contained in a readily accessible position within the pocket 23 for use during IV treatments. The pocket 23 secures the PICC line cap 7 and protects it from dirt, fingers and other infection risks.
The pocket 23 permits easy accessibility to the PICC line 6 for medical professionals when administering infusion therapies without the need to remove the external small length of the PICC line 6 from the securing strap 19 or slit opening 16.
The slit opening 16, the strap 19 and the external pocket 23 are all substantially parallel with each other. The slit opening 16, the strap 19 and the external pocket 23 are all stretchable such that they apply sufficient compression force for holding the external small length of the PICC line 6 and the distal end cap 7 on the patient's arm 11 such that this force does not substantially affect circulation in the limb, and keeps the external small length of the PICC line 6 in place during treatment, sleep, and normal activities.
The slit opening 16, the strap 19 and the external pocket 23 prevent the external small length of the PICC line 6 and the distal end cap 7 from contacting the patient's skin, eliminating the need for additional medical tape to secure the PICC line 6 or the cap 7. This reduction of medical tape in the dressing reduces skin irritation for the patient.
In embodiments of the subject invention, the sleeve 1, the strap 19 and the external pocket 23 may all be composed of a slightly flexible and lightweight fabric that stretches over a patient's arm 11 and is non-irritating to the skin. In embodiments of the subject invention, this fabric may be natural fibers, such as cottons, wools, silks, twills, cloths and bamboo; man-made fibers such as polyesters, nylons, tencels, viscose; or any combination of natural or man-made fibers and weaves.
The chest wrap 25 is a substantially flat wrap with a first end 27, a second end 28, an internal surface 29, shown in
As illustrated in
The looped 35 chest wrap 25 forms a second lumen 36, or internal cavity that is substantially parallel with the longitudinal axis. The lumen 36 defines a top opening 37 that is substantially perpendicular to the longitudinal axis, and further defines a bottom opening 38 that is substantially perpendicular to the longitudinal axis. The top opening 37, the bottom opening 38, and the lumen 36 are all configured for receiving and holding a patient's chest 39. In use, as illustrated in
In one embodiment of the subject invention, the looped 35 chest wrap 25 may have a substantially equal diameter from the top opening 37 to the bottom opening 38. In another embodiment of the subject invention, the chest wrap 25 may have slightly taped diameter from the top opening 37 to the bottom opening 38. This slightly tapered diameter embodiment may be used to accommodate a larger chest 39.
In embodiments of the subject invention, the cross-sectional shape of the looped 35 chest wrap 25 may be substantially circular or substantially elliptical.
The chest wrap 25 is stretchable so as to allow the chest wrap 25 to be easily slipped on and off a patient's chest 39. This fabric should apply sufficient inward compression force such that the chest wrap 25 should substantially conform to the anatomy of a patient's chest 39, such that compression force of the chest wrap 25 does not substantially affect circulation in the limb, remains in place during treatment, remains in place while the patient sleeps, and remains in place if the patient moves or engages in normal activities. This compression force should be inward compression that is substantially equal over the internal surface 29 of the chest wrap 25. The chest wrap 25 fabric allows it to remain in place on the patient's chest and secure the central venous catheter 31 in place.
The end of the small length of the Central venous catheter 31 contains a cap 32. This cap 32 must be periodically replaced, typically weekly, to reduce the risk of contamination. Replacing the cap 32 must also be a sterile procedure that is conducted with washed hands, sterile gloves, sterile clothing, and alcohol swaps in a sterile environment.
The insertion point 40 of the Central venous catheter 31 may be covered with a traditional removable bandage 43. In this embodiment, this removable bandage 43 should only cover a very small portion of the external small length of the Central venous catheter 31 that is proximate to the insertion point 40.
In one embodiment of the subject invention, the chest wrap 25 may comprise a flexible substantially transparent or semi-transparent window (not shown) that traverses the external 30 and internal surfaces 29 of the looped 35 chest wrap 25. The chest wrap 25 should be aligned over the patient's chest 39 such that the flexible substantially transparent or semi-transparent window is over the Central venous catheter insertion point 40. In another embodiment of the subject invention, this substantially transparent window may be composed of a mesh or mesh-like material.
The chest wrap 25 is designed to cover and protect both the chest 39 and external short length of the Central venous catheter 31. The sleeve covers the Central venous catheter insertion area 40 and protects it from clothing, rubbing, and other external influences.
The chest wrap 25 comprises a first slit opening 44 proximate to the Central venous catheter insertion point 40. This slit opening 44 passes through the internal surface 29 to define an internal opening 45 that may be substantially parallel to the longitudinal axis of the looped 35 chest wrap 25. The slit opening 44 further passes into the internal lumen 47, beneath the external surface 30 to define an external opening 46 that may be substantially parallel to the longitudinal axis. The slit opening 44, the internal opening 45, the external opening 46, and the internal lumen 47 are all configured for receiving and removably holding the external small length of the Central venous catheter 31. In use, a patient moves the external small length of the Central venous catheter 31 and the distal end cap 32 through the slit opening 44 into the internal lumen 47 of the chest wrap 25.
Once the external small length of the Central venous catheter 31 is passed through slit opening 44, the Central venous catheter 31 is wrapped around the chest 39 of the patient through internal lumen 47.
The chest wrap 25 comprises a second slit opening 48. This slit opening 48 passes through the internal lumen 47 to define an internal opening 49 that may be substantially parallel to the longitudinal axis of the looped 35 chest wrap 25. The slit opening 48 further passes onto the external surface 30 to define an external opening 50 that may be substantially parallel to the longitudinal axis. The slit opening 48, the internal opening 49, and the external opening 50, are all configured for receiving and removably holding the external small length of the Central venous catheter 31. In use, a patient moves the external small length of the Central venous catheter 31 and the distal end cap 32 through the slit opening 48 onto the external surface 30 of the chest wrap 25.
The chest wrap 25 comprises a third slit opening 56. This slit opening 44 passes through the external surface 30 to define an internal opening 57 that may be substantially parallel to the longitudinal axis of the looped 35 chest wrap 25. The slit opening 56 further passes into a second lumen 59, beneath the external surface 30 to define an external opening 58 that may be substantially parallel to the longitudinal axis. The second lumen 59 is between the internal surface 29 and the external surface 30. The slit opening 56, the internal opening 57, the external opening 58, and the second internal lumen 59 are all configured for receiving and removably holding the external small length of the Central venous catheter 31. In use, a patient moves the external small length of the Central venous catheter 31 and the distal end cap 32 through the slit opening 56 into the internal lumen 47 of the chest wrap 25.
The chest wrap 25 further comprises a substantially flat strap 51 on the external surface 30. This strap 51 comprises a first end 52 and a second end 53 that are both attached to the external surface 30 of the chest wrap 25. The strap 51 may be substantially rectangular or square in shape. The central portion of the strap 54 is unattached to the chest wrap 25 to form a strap opening 55 that is configured for receiving and removably holding the external small length of the Central venous catheter 31 underneath the second lumen 59. This strap opening 55 may be substantially parallel to the longitudinal axis. In use, a patient moves the external small length of the Central venous catheter 31 and the distal end cap 32, already passed through the slit opening 48 into the second lumen 59, through the strap opening 55 underneath strap 51.
The strap 51 permits easy accessibility to the Central venous catheter 31 for medical professionals when administering infusion therapies without the need to remove the external small length of the Central venous catheter 31 from the slit opening 48 and the second lumen 59.
The slit opening 44, the slit opening 48, the slit opening 56, and the strap 51 are all substantially parallel with each other. The slit opening 44, the slit opening 48, the slit opening 56, and the strap 51 all comprise a fabric that applies sufficient compression force for holding the external small length of the Central venous catheter 31 and the distal end cap 32 on the patient's chest 39 such that this force does not substantially affect circulation, and keeps the external small length of the Central venous catheter 31 in place during treatment, sleep, and normal activities.
The slit opening 44, the slit opening 48, the slit opening 56, and the strap 51 prevent the external small length of the Central venous catheter 31 and the distal end cap 32 from contacting the patient's skin, eliminating the need for additional medical tape to secure the Central venous catheter 31 or the cap 32. This reduction of medical tape in the dressing reduces skin irritation for the patient.
In embodiments of the subject invention, the chest wrap 25, and the strap 51 may all be composed of a slightly flexible and lightweight fabric that stretches over a patient's chest 39 and is non-irritating to the skin. In embodiments of the subject invention, this fabric may be natural fibers, such as cottons, wools, silks, twills, cloths and bamboo; man-made fibers such as polyesters, nylons, tencels, viscose; or any combination of natural or man-made fibers and weaves.
