Definitions
- This invention relates generally to catheters with injection ports, such as peripherally inserted central catheters, and more particularly to devices for securing access to them for outpatient safety.
- Abusers of intravenous drugs such as heroin are susceptible to severe infections which must be treated by intravenous injection of antibiotics over a course of many weeks.
- the drug abuser may be provided with an intravenous peripherally inserted central catheter or PICC line.
- This catheter while usually inserted in the hospital, can remain in place for weeks or months, and makes it a simple matter to rapidly inject the necessary antibiotics without difficulty in finding a vein.
- This ease of intravenous access can be a serious hazard for outpatients who are habitual drug abusers, who can take advantage of this catheter to self-administer unprescribed quantities of narcotics or other controlled substances.
- the device of the present invention serves as a lock for an outpatient's peripherally inserted central catheter (PICC) line which limits access to the catheter by patients seeking to abuse injectable narcotics.
- the lock has two plastic housing halves which slide together and which define an interior enclosure which receives a catheter line injection port.
- the housing halves have overlying flanges, through which a fastener extends to secure the device in a closed configuration.
- the fastener interacts with the flanges in such a way that it cannot be removed without distorting the device and giving evidence of tampering.
- the locking mechanism may be a dumbbell shaped metal pin, which is inserted through aligned openings in the aligned flanges by a small handheld press.
- FIG. 1 is a schematic view of a PICC line in connection with a patient and the function of the PICC line lock of this invention.
- FIG. 2 is an exploded isometric view of the PICC line lock of this invention.
- FIG. 3 is an enlarged fragmentary cross-sectional view of the PICC line lock of FIG. 2 as a locking member is being inserted within a hand press.
- FIG. 4 is a side elevational view of a the device of FIG. 3 in a locked configuration.
- FIG. 5 is a fragmentary cross-sectional view of an alternative embodiment locking mechanism for the PICC line lock of this invention, using a one-way screw.
- FIG. 6 is a perspective view of a sleeve assembly for protecting the PICC line between the inlet port and the base.
- FIG. 7 is a fragmentary cross-sectional view of the device of FIG. 6 received within a locked housing.
- FIG. 2 a PICC line lock 20 for use with conventional PICC line assemblies 24 is shown in FIG. 2 .
- a PICC line assembly 24 as shown in FIG. 1 , has a catheter 26 which is inserted into an upper extremity 28 of the patient 30 , for example an arm.
- the assembly 24 will typically have a base 32 which is taped to the patient.
- One or more injection lines 34 extends from the base, each of which is terminated by an inlet port 36 .
- the inlet ports 36 provide an entryway to the injection lines 34 for delivery of fluids from an injection source such as a syringe 40 or a total parenteral nutrition bag or whatever injectable the patient requires.
- the inlet ports may be provided with a positive displacement connector 37 , such as the MaxPlus® clear needleless connector made by Carefusion Corporation of San Diego, Calif., and such as disclosed in U.S. Pat. No. 5,730,418, the disclosure of which is incorporated by reference herein.
- the lock 20 provides a mechanism for blocking access to the inlet ports 36 by the patient.
- the injection lines 34 may be provided with one or more mechanical clamps 42 which serve to prevent the escape or entry of liquids into the lines unless the clamps 42 are removed.
- the lock 20 comprises a box or housing 44 formed by the assembly of a first housing half 46 and a second housing half 48 .
- the housing halves 46 , 48 may be injection molded plastic parts formed, for example, of high density polyethylene.
- the housing halves have cooperating structures which allow the halves to be slid together to define a housing compartment 50 of adequate dimensions to receive an inlet port 36 and any associated connector 37 and to protect the port from access by the patient.
- the housing 44 may thus be long enough to include a 2-inch long combined inlet port and connector.
- the second housing half 48 may have two parallel projecting T-rails 52 , which are received in two parallel T-slots 54 allowing the two halves to slide together.
- the second housing half 48 has a bottom wall 56 with a projecting side wall 58 in which is formed a tapered V-shaped slot 60 which serves as a clamp for the injection line leading out of the inlet port which is received within the housing compartment 50 .
- This slot acting as a clamp provides another opportunity to stop the flow of liquids through the line, even if an intermediate clamp should fail.
- the second housing half 48 may be provided with an intermediate wall 62 located within the housing compartment 50 which defines a channel 64 between the end wall and the intermediate wall which will receive the conventional clamp 42 that locks the PICC line and which is typically a part of the PICC line assembly.
- the housing 44 is dimensioned to create a snug fit for the PICC line assembly comprised of the inlet port 36 , the positive displacement connector 37 , if any, and the attached inlet line 34 , so that these components do not have the space to rotate and become dislodged. Even if rotational forces act on the end assembly, the lack of space to expand will not allow the clamps to become dislodged.
- the second housing half 48 may have two thin molded lower tabs 102 , shown in FIG. 2 .
- the tabs extend from opposite sides of the second housing half and are flexible to conform to a patient's limb to allow adhesive tape to extend over the tabs to permit the housing 44 to be taped to a patient's body.
- the first housing half 46 has a first flange 66 which protrudes away from the housing, and the second housing half 48 has a second flange 68 which protrudes beneath the first flange 66 .
- the first flange has a cylindrical opening 70 which aligns with a blind cylindrical opening 72 in the second flange 68 when the two housing halves are slid together into a locked configuration.
- a metal locking fastener 74 is inserted into the aligned openings 70 , 72 , with a hand press 76 , shown in FIG. 3 .
- the hand press 76 has a mechanism similar to a conventional two-hole press, with a lever 77 which may be depressed to drive the locking fastener 74 into place.
- the fastener 74 may have a narrower-diameter segment 78 which gives it a dumbbell-like shape which allows the plastic of the flanges 66 , 68 to deform into the narrower-diameter segment and thus lock the fastener 74 in place and connect the first housing half 46 to the second housing half 48 in such a fashion that the fastener cannot be removed without distorting the device 20 and giving evidence of tampering with the device.
- the housing is returned to the hand press 76 , and the lever 77 is fully depressed to engage the fastener 74 and to drive it out through the lower flange 68 of the housing.
- a through hole 79 in the lower member 81 of the press 76 allows passage for the fastener therethrough.
- FIG. 5 A housing with an alternate locking mechanism 103 is shown in FIG. 5 , which uses a fastener 104 similar to a conventional one-way screw, such as is used in bathroom stalls.
- the housing has a first flange 106 with a through hole 107 which overlies a second flange 108 with a blind hole 110 .
- the one-way screw fastener can be turned in one direction to be tightened, but cannot be removed without a special tool.
- portions of the plastic of the upper first flange 106 expand over the outside diameter of the screw head.
- the base of the screw head's outside diameter acts like a small washer that is integral to the screw head.
- the lip will expand over the integral washer and lock the screw in place.
- An authorized person can use a specialized screwdriver to remove the screw. Even if the patient were to gain access to the specialized screwdriver, the deformation of the plastic around the screw head would provide evidence that the housing had been tampered with.
- a zip tie is a nylon cable tie comprised of a tape section with triangular teeth that slope in one direction.
- the head of the cable tie has a slot with a flexible pawl that irreversibly rides up the slope of these teeth when the tape is inserted. The pawl engages the backside of these teeth to stop removal of the tape.
- these ties must be cut to be removed.
- the two housing halves are slid together about the inlet port, and then connected with the fastener to lock out access to the inlet port.
- the lock 20 will stay in place until the authorized person returns on the next visit to administer another injection.
- the hand press 76 is used to punch out the fastener 74 and thereby allow the housing halves to be slid apart and the inlet ports to be accessed.
- the lock 20 is opened, it is destroyed, and cannot be reused.
- the sleeve assembly 80 has a wrap-around sleeve 82 made out of a puncture resistant material, such as plastic or fabric formed of KEVLAR® para-aramid synthetic fibers.
- the sleeve assembly 80 has an axially extending zipper closure 84 fixed to the sleeve 82 . By actuating the zipper closure, the sleeve is rolled up into a tube which surrounds and receives the line 34 to thus cover the line as it extends to an inlet port 36 .
- the zipper closure 84 has a protruding pull tab 92 , which serves to advance the zipper to engage the two strips of zipper teeth 93 and close the sleeve.
- the pull tab 92 and portions of the sleeve are received within a box or housing 98 .
- the protruding pull tab 92 is larger than the opening 100 in the housing, thus preventing the sleeve assembly from being extracted from the housing 98 once it is locked closed in a manner similar to the device 20 described above.
- the sleeve assembly 80 may not be removed without destroying the housing.
- an internal clamp may be provided in an internal wall 105 .

Abstract
Description
- This application claims the benefit of priority of U.S. provisional patent app. No. 61/809,440, filed Apr. 8, 2013, the disclosure of which is incorporated by reference herein.
- Not applicable.
- This invention relates generally to catheters with injection ports, such as peripherally inserted central catheters, and more particularly to devices for securing access to them for outpatient safety.
- Abusers of intravenous drugs such as heroin are susceptible to severe infections which must be treated by intravenous injection of antibiotics over a course of many weeks. To facilitate this treatment, the drug abuser may be provided with an intravenous peripherally inserted central catheter or PICC line. This catheter, while usually inserted in the hospital, can remain in place for weeks or months, and makes it a simple matter to rapidly inject the necessary antibiotics without difficulty in finding a vein. This ease of intravenous access, however, can be a serious hazard for outpatients who are habitual drug abusers, who can take advantage of this catheter to self-administer unprescribed quantities of narcotics or other controlled substances. Providing a drug abuser with an unsupervised PICC line for outpatient care can lead to illegal drug overdose and death. To protect these high risk patients, who might otherwise not need full-time nursing care, they must be hospitalized and retained under supervision for the multiple weeks that the antibiotics are needed. Hospitalization is vastly more costly than outpatient care, and represents a less than optimal utilization of health care resources.
- What is needed is an arrangement which allows drug abusing patients to be safely outfitted with PICC lines for outpatient care.
- The device of the present invention serves as a lock for an outpatient's peripherally inserted central catheter (PICC) line which limits access to the catheter by patients seeking to abuse injectable narcotics. The lock has two plastic housing halves which slide together and which define an interior enclosure which receives a catheter line injection port. The housing halves have overlying flanges, through which a fastener extends to secure the device in a closed configuration. The fastener interacts with the flanges in such a way that it cannot be removed without distorting the device and giving evidence of tampering. The locking mechanism may be a dumbbell shaped metal pin, which is inserted through aligned openings in the aligned flanges by a small handheld press. Each time an intravenous treatment is administered, the pin is extracted by the press and the locking device is destroyed and replaced with a new one. Should the patient remove the box to defeat its restrictions, the damage to the box provides ready evidence to the nurse that the patient has tampered with the device, providing grounds for returning the patient to the hospital.
- It is an object of the present invention to provide a device which limits undetected access to the inlet ports of a PICC line.
- It is another object of the present invention to provide a tamper-evident lock for a PICC line.
- Further objects, features and advantages of the invention will be apparent from the following detailed description when taken in conjunction with the accompanying drawings.

FIG. 5 is a fragmentary cross-sectional view of an alternative embodiment locking mechanism for the PICC line lock of this invention, using a one-way screw. -
FIG. 6 is a perspective view of a sleeve assembly for protecting the PICC line between the inlet port and the base. -
FIG. 7 is a fragmentary cross-sectional view of the device ofFIG. 6 received within a locked housing. - Referring more particularly to
FIGS. 1-7 , where like numbers refer to similar parts, aPICC line lock 20 for use with conventionalPICC line assemblies 24 is shown inFIG. 2 . APICC line assembly 24, as shown inFIG. 1 , has acatheter 26 which is inserted into anupper extremity 28 of thepatient 30, for example an arm. Theassembly 24 will typically have abase 32 which is taped to the patient. One ormore injection lines 34 extends from the base, each of which is terminated by aninlet port 36. Theinlet ports 36 provide an entryway to theinjection lines 34 for delivery of fluids from an injection source such as asyringe 40 or a total parenteral nutrition bag or whatever injectable the patient requires. The inlet ports may be provided with apositive displacement connector 37, such as the MaxPlus® clear needleless connector made by Carefusion Corporation of San Diego, Calif., and such as disclosed in U.S. Pat. No. 5,730,418, the disclosure of which is incorporated by reference herein. Thelock 20 provides a mechanism for blocking access to theinlet ports 36 by the patient. Theinjection lines 34 may be provided with one or moremechanical clamps 42 which serve to prevent the escape or entry of liquids into the lines unless theclamps 42 are removed. - As shown in
FIG. 2 , thelock 20 comprises a box orhousing 44 formed by the assembly of afirst housing half 46 and asecond housing half 48. Thehousing halves housing compartment 50 of adequate dimensions to receive aninlet port 36 and any associatedconnector 37 and to protect the port from access by the patient. Thehousing 44 may thus be long enough to include a 2-inch long combined inlet port and connector. Thesecond housing half 48 may have two parallel projecting T-rails 52, which are received in two parallel T-slots 54 allowing the two halves to slide together. Thesecond housing half 48 has abottom wall 56 with a projectingside wall 58 in which is formed a tapered V-shaped slot 60 which serves as a clamp for the injection line leading out of the inlet port which is received within thehousing compartment 50. This slot acting as a clamp provides another opportunity to stop the flow of liquids through the line, even if an intermediate clamp should fail. - The
second housing half 48 may be provided with anintermediate wall 62 located within thehousing compartment 50 which defines achannel 64 between the end wall and the intermediate wall which will receive theconventional clamp 42 that locks the PICC line and which is typically a part of the PICC line assembly. Thehousing 44 is dimensioned to create a snug fit for the PICC line assembly comprised of theinlet port 36, thepositive displacement connector 37, if any, and the attachedinlet line 34, so that these components do not have the space to rotate and become dislodged. Even if rotational forces act on the end assembly, the lack of space to expand will not allow the clamps to become dislodged. - The
second housing half 48 may have two thin moldedlower tabs 102, shown inFIG. 2 . The tabs extend from opposite sides of the second housing half and are flexible to conform to a patient's limb to allow adhesive tape to extend over the tabs to permit thehousing 44 to be taped to a patient's body. - The
first housing half 46 has afirst flange 66 which protrudes away from the housing, and thesecond housing half 48 has asecond flange 68 which protrudes beneath thefirst flange 66. As shown inFIG. 3 , the first flange has acylindrical opening 70 which aligns with a blindcylindrical opening 72 in thesecond flange 68 when the two housing halves are slid together into a locked configuration. Ametal locking fastener 74 is inserted into the alignedopenings hand press 76, shown inFIG. 3 . Thehand press 76 has a mechanism similar to a conventional two-hole press, with alever 77 which may be depressed to drive thelocking fastener 74 into place. Thefastener 74 may have a narrower-diameter segment 78 which gives it a dumbbell-like shape which allows the plastic of theflanges fastener 74 in place and connect thefirst housing half 46 to thesecond housing half 48 in such a fashion that the fastener cannot be removed without distorting thedevice 20 and giving evidence of tampering with the device. To open thehousing 44 and remove thefastener 74, the housing is returned to thehand press 76, and thelever 77 is fully depressed to engage thefastener 74 and to drive it out through thelower flange 68 of the housing. A throughhole 79 in thelower member 81 of thepress 76 allows passage for the fastener therethrough. - A housing with an
alternate locking mechanism 103 is shown inFIG. 5 , which uses afastener 104 similar to a conventional one-way screw, such as is used in bathroom stalls. The housing has afirst flange 106 with a throughhole 107 which overlies asecond flange 108 with ablind hole 110. The one-way screw fastener can be turned in one direction to be tightened, but cannot be removed without a special tool. When thefastener 104 is fully inserted, portions of the plastic of the upperfirst flange 106 expand over the outside diameter of the screw head. The base of the screw head's outside diameter acts like a small washer that is integral to the screw head. The lip will expand over the integral washer and lock the screw in place. An authorized person can use a specialized screwdriver to remove the screw. Even if the patient were to gain access to the specialized screwdriver, the deformation of the plastic around the screw head would provide evidence that the housing had been tampered with. - It should be noted that other fasteners may be used the removal of which gives evidence of tampering, for example a zip tie or tie-wrap extending through openings in the halves of the housing. A zip tie is a nylon cable tie comprised of a tape section with triangular teeth that slope in one direction. The head of the cable tie has a slot with a flexible pawl that irreversibly rides up the slope of these teeth when the tape is inserted. The pawl engages the backside of these teeth to stop removal of the tape. Typically these ties must be cut to be removed.
- Once an injection has been made through the PICC line by an authorized person, the two housing halves are slid together about the inlet port, and then connected with the fastener to lock out access to the inlet port. The
lock 20 will stay in place until the authorized person returns on the next visit to administer another injection. To remove thelock 20, thehand press 76 is used to punch out thefastener 74 and thereby allow the housing halves to be slid apart and the inlet ports to be accessed. When thelock 20 is opened, it is destroyed, and cannot be reused. Should a patient attempt to pry apart the housing or otherwise tamper with the lock to separate the housing halves, it would be apparent to the authorized person on the next visit, indicating that the patient was not a suitable candidate for in-home care, and should be returned to hospital care. - To prevent access to the
lines 34 between the inlet ports and the base 32 asleeve assembly 80, shown inFIGS. 6-7 , may be provided. Thesleeve assembly 80 has a wrap-aroundsleeve 82 made out of a puncture resistant material, such as plastic or fabric formed of KEVLAR® para-aramid synthetic fibers. Thesleeve assembly 80 has an axially extendingzipper closure 84 fixed to thesleeve 82. By actuating the zipper closure, the sleeve is rolled up into a tube which surrounds and receives theline 34 to thus cover the line as it extends to aninlet port 36. Thezipper closure 84 has a protrudingpull tab 92, which serves to advance the zipper to engage the two strips of zipper teeth 93 and close the sleeve. Thepull tab 92 and portions of the sleeve are received within a box orhousing 98. The protrudingpull tab 92 is larger than theopening 100 in the housing, thus preventing the sleeve assembly from being extracted from thehousing 98 once it is locked closed in a manner similar to thedevice 20 described above. Once locked inside thehousing 98 thesleeve assembly 80 may not be removed without destroying the housing. Because theopening 100 must be large enough to admit the sleeve without obstruction, it does not serve as a line clamp. Hence an internal clamp may be provided in an internal wall 105. In addition, the line may have itsown clamp 42. As shown inFIG. 7 , thebase 32 may be mounted to the limb of the patient by a bandage or dressing 112. - It should be noted that additional clamps similar to the
ones 42 shown inFIG. 2 , can be provided within the housing. Two clamps can be positioned within each compartment 116, 118, defined by the dividingwalls 120. In each pair of clamps, oneclamp 42 can have the clamp opening facing in one direction, and theother clamp 114 can have the clamp opening facing in the other direction. - It is understood that the invention is not limited to the particular construction and arrangement of parts herein illustrated and described, but embraces all such modified forms thereof as come within the scope of the following claims.
