l~ack~rrol~ld of tile Invention This invention relates to medical apparatus including fluid condui~s having a tamp~r~evidcnt ;ndicator and more particularly to such apparatus wherein the tamper-evident indicator is provided at the juncture of interconnected sections of the medical fluid conduits to provide an indication that the sections have or have not been disconnected and then reconnected.
Human body fluid drainage systems, such as urine ~ollection systems, often include a catheter, such as a Foley catheter, having its distal end disposed in 10 the bladder of a patient and the proximal end connected to a tube conneetor or ada~
tor of a drainage tube which connec$s the catheter with a urine collection container or bagr~
Such Foley catheters are often maintained in position in a hospitalized patient and connected to the drainage bag for substantial periods of time. To avoid 15 patient infections, such components are usually sold in a sterile condition. However, if the components are packaged and sold separately, there is a danger of bacteria entering the urine drainage system upon assembly and connection of the catheter to the drainage tube in the field, such as in a hospital and thereby causing urinary tract infection of a patient. To avoid the possibility of bacteria entering the system at 20 the time of connection at the juncture of the catheter and drainage tube, some man-ufacturers preconnect the catheter and drainage tube at the factory, sterilize the preconnected system, and package and sell the system in the assembled condition.Certain hospital requirements necessitate the disconnection and recon-nection of the catheter and drainage tube of urine collection systems such as where 25 a replacement bag is required or bladder irrigation is desired without the removal of the original catheter from the patient. Additionally, patients sometimes are moti-vated to disconnect the drainage bag and tube from the catheter without authoriza-tion for reasons of patient mobility, convenience, comfort and the like. It is, of course, important to hospital personnel to know if the system connectors have been 30 tampered with or if disconnection and reconnection of the connectors has occurred, whether or not such was for an authorized purpose. F or example, when monitoringor measuring urine drainage, it is necessary to know if there has been a disconnection of the urine collection container from lhe catheter in order to have confidence in the determination of total amount of urine passed.
In order to provide an assured indication that the eatheter has or has not been disconnected and reconnected, a tamper-evident seal has been suggested. For 1 7rJ /~ 7~
exainple, U.S. Patent No. 4,194,5()~ to Pickering et al proposes a tarnper-evident shrink band or wrap which seals the j~ncture oî the catheter and dr~in~ge tub~ ada~
tor prior to sterili~.ation. 1 his heat sllri~kable wrap of Pickering et al consists of a length of heat shrinkable adhesive tape and a circumferentially extending tear strip Inade o~ a shrinkable resin, for example, a polyolefin such as a polyethlene. In order to apply this wrap inaterial, a heat source must be used to shrink the wrap and this tends to complicate the overall manlfa~t~re and assembly of the system. When thetamper-evident indicator or seal of Pickering et al is in position, it conceals the junc~ure of the adaptor and the funnel connector of the Pickering et al device there-10 by making it subsequently difficult ~o ascertain that a proper, fluid-tight cngagement exists between these elements. In order to disconnect these elements for any purpose, the tear strip of Pickering et al must be located, gripped and tangantially pulled away from the adaptor to thus remove half of the wrap from the remainder thereofand thus rnak;ng removal unnecessarily complicated. Additionally, after that portion 15 of the wrap on the adaptor of the Pickering et al device is r emoved with the tear strip from the rcmainder of the wrap of the indicator remaining on the funnel con-nector, it is not always apparent from the smooth band OI wrap remaining that the connection between the adaptor and the funnel connectvr has been previously broken.
_umm ary of the Invention An object of the present invention is to provide a medical apparatus including a pair of conduit sections coupled together and provided with an improved tamper-evident indicator for the conduit coupling wherein one or more of the above mentioned problems or disadvantages are overcome.
Another object of the present invention is to provide an improved tamper-25 evident indicator for interconnected tube connectors which is easy to apply during assembly, is constructed of economic~l material, provides an obvious and continuing indication that the tube connectors have or have not been disconnected, and which does not interfere or complicate in any way with the disconnection of the connectors Cor legitimate purposes.

These as vvell as other objects and advantages of the present invention 10 will become apparent frolll the following detailed description and accompanying drawing.

Fig. 2 is a fragmentary side view on an enlarged scale, of the drainage tube connector and the catheter connector of the system shown in Fig. 1 but shown before the tube connectors are interconnected;
Fig. 3 is a fragmentary view OI the connectors shown in Fig. 2 after they 20 have been interconnected and after the tamper-evident indicator shown in Fig. 1 has been applied thereto; and Fig. 4 is a plan view of a tamper-evident indicator shown in Fig. 3 but shown in a flattened condition, as before being applied to the remainder of the system showninFig. 1.
25 Description of the Preferred Embodiment Referring now in more detail to the drawings, and more particularly to Fig. 1, a preconnected or closed system urinary drainage system 10 is shown including a conventional urinary drainage collection assembly 12 connected to a conventional Foley catheter assembly 14, and a tamper-evident indicator 16 at the junction of the 30 assemblies 12 and 14 in accordance to the present invention.
TheFoley catheter assembly 14 conventionally includes a flexible tube 18 having an inflatable balloon or cuff 20 near its distal end. The tube 18 is provided with a longitudinally extending inflation lumen (not shown) in its sidewall which is connected at its distal end to an opening 21 in the sidewall of the tube and to the 35 interior of and between the ends of the cuff, and to an inflation tube 22 projecting 7 r! 7 ~ t~`~
in a "~-s~lape" arrangcrncr1t ~t a side of its proxiMal end. ~nflation tube 22 h,lS a norrnally closed valve ~ at the proximal el~d of tube 18. The valve 24 may be any suitable check valve desi~rn ~hich can b~ opera~ed b~ a syringe or the like for inflat-ing and deflatin~ the cuff in the conventional manner. One or more inlet openin~s 5 19 in the sidewall Or tube 18 at the distal end connect with the main lumen, indicated at 23, of the tube 18. Tube 18 has a runnel-shaped female tube c~nnector 26 having a longitudinal end 27 at the proximal end of the catheter assembly 14 to connect the catheter ~ssernbly to the drainage collection assembly 12. Connector 26 is shown as an integral funnel connector having tapered or conical inner and outer walls, as also 10 seen in Figs. 2 and 3. The inner walls of connector 26 may be provided with axially spaced friction rings 25. The catheter tube 18 and inflation tube 22 rnay be made of any suitable soft and flexible conventional material, for example, a material that includes silicone or latex. Such materials provide a catheter which is soft and pliable to minimize patient discornfort.
The urinary drainage collection assembly 12 is shown including a urine collection container in the form of a flexible bag 28 having an outlet 29 and a $ube clamp 30 for closing and opening the outlet. A urine drainage tube 31, having a longitudinally extending drainage lumen, and which may be made of any suitable plastic such AS a polyvinyl chloride, is connected at its proximal end to the interior 20 of bag 28, and is connected at its distal end to a male or adaptor tube connector 32.
The male tube connector 32, as best seen in Fig. 2, has a distal end coupling portion 33 having a tapering or generally conical outer coupling surface with a plurality of cylindrical steps decreasing in diameter in the distal direction and indicated at 34, and a longitudinal end 35 at the distal end. The coupling portion 33 is sealingly and 25 frictionally received in the female funnel connector 26 of catheter assembly 14 to connect the distal end openings 19 of the catheter in fluid communication with the interior of collection bag 28. The steps or lands 34 cooperate with the inner surface of the inner walls and friction rings 25 in effecting a good seal between the connectors.
The connector 32 also has an annular flange 39 and a cylindrical portion 37, the30 flange 3g being disposed axially between the cylindrical portion 37 and coupling portion 33. The diameter of flange 39 is greater than that of cylindrical portion 37 and provides a finger stop to facilitate connecting the connector 32 with funnelconnector 26. Cylindrical portion 37 is of greater diameter than that of coupling portion 33. The tube connector 32 is shown having a vent with a filter at 41, and it 35 may also include a conventional anti-reflux valve (not shown) to prevent back flow from bag 28 to the catheter 14. Figure 2 shows the connector 32 disconnected from the funnel connector 26 and before the tamper-evident indicator 16 has been applied r~,;
accord;ng~ to thc prcse~t inYcn~ion. C~nnector 32 JlSIS a bore or lumen in~icated in phantom at 43 in ~:ig. 2.
~ ter ~he rnale tllbe ss)nnectolo 32 and fernale funnel connector 26 have been rnutllally engaged and intercor1necte(1 in fluid tight coupling engagement, the 5 tamper-evident indicator 16 is positioned and connected at the juncture of the con-nectors as shown in ~ig. 3. The indicator 16 according to the present invention in-cludes an adaptor connecting strip 36 having a length greater than the circumference of, and adapted to be wrapped about, the cylindrical portion 37 (~ig. 2) of the male adaptor connector 32. Additionally, indicator 16 has a similar second or fi~nnel con-necting strip 38 that is adapted to be wrapped about the cat11eter fernale connector 10 26 and has a length greater than the circumference of that portion of the female connector 26 about which it is adapted to be wrapped. A pair of transversely cir-cumferentially spaced severable, tearable or breakable indicator strips 40 and 42 are connected between the connecting strips 36 and 38. While two indicator strips 40and 42 are shown in the drawing one such strip is generally suficient.
The indicator 16 is shown in Fig. 4 as a unitary or single piece member and in its manufactured and flattened state. It is formed of an easily tearable paper, preferably with an adhesive (not shown) applied at least to end portions of the con-necting strips and may be applied to the entire one side of the connecting strips of the indicator. The connecting strip 36 is shown in Fig. 4 extending vertically and 20 having upper and lower ends, which ends overlap when applied to the cylindrical portion 37 of the connector 32, as shown in Fig. 3. The overlapping ends are connected together by the adhesive. The funnel connecting strip 38 is shorter than the adaptor connecting strip 36 because the circumference of the funnel at the strip mounting point is less than the circumference of the adaptor connector at portion 37. The25 connecting strip 38 is shown having an upper portion 44 extending at a slight angle, such as 8 from a vertical line, and inclined toward the connecting strip 36. Similar-ly, a lower portion 46 of connecting strip 38 connects with portion 44 and also extends at an angle, for example, 8 from a vertical line and toward the connecting strip 36.
Portions 44 and 46 connect at a point on a horizontal line intersecting the center of 30 connecting strip 36. The axially or transversely extending indicator strips 40 and 42 extend from connecting strip 36 at locations spaced from the opposite ends of strip 36 and rightwardly at an angle, for example, 8 from a horizontal line with eachinclined toward each other in the direction of strip 38. By forming the indicator strips 40 and 42 spaced from each other and parts of the indicator 16 at angles, as 35 described herein, the connecting strip 38 will be readily wrapped around the relative-1~,7 smaller circumference of the catheter connector 26 with the opposed ends thereof '3' -7 ~ ~1 f;

l\Then the indicator 16 is applied to the $ube connectors 26 and 32, the indicator strips 40 and 42 will extend longitudinally or a~ially across the juncture of the connectors 26 and 32 and be diame~rically spaced from each other. Such strips will not be wrapped about or entirely conceal the juncture. After the indicator 16 10 has been applied at the juncture of the connectors 26 and 32, the entire assembly 10 may then be sterilized and packaged.
The tamper-evident ind;cator 16 may be stamped out of a suitable paper in the form shown in Fig. 4, wh;ch paper may be any suitable severable or te~able paper such as conventional wood pulp paper or the like, and may either be coated15 with a wetable-and-subsequently-hardening glue for attaching it to the tube conne~
tors 26 and 32 or it may be of a pressure sensitive adhesive of the type in which a protective sheet of material (not shown) is peeled away to present one side of the material with an adhesive that does not harden and that can be applied directly to the connectors without wetting. One side of indicator 16 may be entirely coated 20 with adhesive or only one of the overlapping ends of each of the connecting strips 36 and 38 may be adhesively coated. If desired, only the encircling connecting portions 36 and 38 may be coated with an adhesive. With the opposite ends of each of the connecting strips 36 and 38 overlapping and adhesively connected together it is not necessary that these strips be adhesively connected to both tube csnnectors 26 and 25 32. For example, where the catheter 18 is of silicone, some adhesives will not tight-ly adhere to the catheter, however, the ends of connecting strip 38 overlap and are tightly adhesively connected together so that strip 38 is tightly connected to con-nector 26. Some adhesives provide only a tackiness with silicone.
Should it be desired to disconnect the connectors 26 and 32 from each 30 other, the indicator strips 40 and 42 will readily tear or become broken. Upon tear-ing, the torn ends of the indicator strips may curl outwardly, as shown in phantom lines at 40' and 42' in Fig. 3, thereby making it obvious, even to the casual observer, that the connection has been broken. While two indicator strips or more are desir-able, one can be used. Where the connectors are completely disconnected from each 35 other, both of the indicator strips 40 and 42 will be broken while the connecting strips 36 and 38 will remain secured on the connectors 26 and 32. Even if the con-~ 7 ~
n~c~ors wer e r~connectec] af~er a disconnection, the presence of curled~ or urevenremnant tol n indicltor strips would be a clear indication that ti~e conrles~tors had been disconnec~ed.
Since the indicator strips 4D anc! 42 are relatively narrow, substanti~lly 5 less than the circumference of the connectors 26 and ~32, the jun^ture of the connectors 26 and 32~ including the dis~al side of flange 33, surfaee 34 and îu.~nel connector end ~7, can be seen between the indicatrjr strips when desired so that the indicator strips need not be transparent but can be of any desired color and still not conceal the connector junction. The proximal end 27 of the conical connector 26 provides a 10 iunction line at the juncture of connectors 26 and 32. Also, since the indicator slrips 40 and 42 are easily torn or broken, the indicator does not interfere with, hinder, or complicate the disconnection of the connectors 26 and 32.
As various changes could be made in the above construction without 15 departing from scope of the invention, it is intended that all matter contained in the above description and shown in the accompanying drawing be interpreted as illustra-tive and not in a limiting sense.

The tube 18 is provided with a longitudinally extending inflation lumen (not shown) in its sidewall which is connected at its distal end to an opening 21 in the sidewall of the tube and to the 35 interior of and between the ends of the cuff, and to an inflation tube 22 projecting 7 r! 7 ~ t~`~
in a "~-s~lape" arrangcrncr1t ~t a side of its proxiMal end. ~nflation tube 22 h,lS a norrnally closed valve ~ at the proximal el~d of tube 18. The valve 24 may be any suitable check valve desi~rn ~hich can b~ opera~ed b~ a syringe or the like for inflat-ing and deflatin~ the cuff in the conventional manner. One or more inlet openin~s 5 19 in the sidewall Or tube 18 at the distal end connect with the main lumen, indicated at 23, of the tube 18. Tube 18 has a runnel-shaped female tube c~nnector 26 having a longitudinal end 27 at the proximal end of the catheter assembly 14 to connect the catheter ~ssernbly to the drainage collection assembly 12. Connector 26 is shown as an integral funnel connector having tapered or conical inner and outer walls, as also 10 seen in Figs. 2 and 3. The inner walls of connector 26 may be provided with axially spaced friction rings 25. The catheter tube 18 and inflation tube 22 rnay be made of any suitable soft and flexible conventional material, for example, a material that includes silicone or latex. Such materials provide a catheter which is soft and pliable to minimize patient discornfort.
The urinary drainage collection assembly 12 is shown including a urine collection container in the form of a flexible bag 28 having an outlet 29 and a $ube clamp 30 for closing and opening the outlet. A urine drainage tube 31, having a longitudinally extending drainage lumen, and which may be made of any suitable plastic such AS a polyvinyl chloride, is connected at its proximal end to the interior 20 of bag 28, and is connected at its distal end to a male or adaptor tube connector 32.
The male tube connector 32, as best seen in Fig. 2, has a distal end coupling portion 33 having a tapering or generally conical outer coupling surface with a plurality of cylindrical steps decreasing in diameter in the distal direction and indicated at 34, and a longitudinal end 35 at the distal end. The coupling portion 33 is sealingly and 25 frictionally received in the female funnel connector 26 of catheter assembly 14 to connect the distal end openings 19 of the catheter in fluid communication with the interior of collection bag 28. The steps or lands 34 cooperate with the inner surface of the inner walls and friction rings 25 in effecting a good seal between the connectors.
The connector 32 also has an annular flange 39 and a cylindrical portion 37, the30 flange 3g being disposed axially between the cylindrical portion 37 and coupling portion 33. The diameter of flange 39 is greater than that of cylindrical portion 37 and provides a finger stop to facilitate connecting the connector 32 with funnelconnector 26. Cylindrical portion 37 is of greater diameter than that of coupling portion 33. The tube connector 32 is shown having a vent with a filter at 41, and it 35 may also include a conventional anti-reflux valve (not shown) to prevent back flow from bag 28 to the catheter 14. Figure 2 shows the connector 32 disconnected from the funnel connector 26 and before the tamper-evident indicator 16 has been applied r~,;
accord;ng~ to thc prcse~t inYcn~ion. C~nnector 32 JlSIS a bore or lumen in~icated in phantom at 43 in ~:ig. 2.
~ ter ~he rnale tllbe ss)nnectolo 32 and fernale funnel connector 26 have been rnutllally engaged and intercor1necte(1 in fluid tight coupling engagement, the 5 tamper-evident indicator 16 is positioned and connected at the juncture of the con-nectors as shown in ~ig. 3. The indicator 16 according to the present invention in-cludes an adaptor connecting strip 36 having a length greater than the circumference of, and adapted to be wrapped about, the cylindrical portion 37 (~ig. 2) of the male adaptor connector 32. Additionally, indicator 16 has a similar second or fi~nnel con-necting strip 38 that is adapted to be wrapped about the cat11eter fernale connector 10 26 and has a length greater than the circumference of that portion of the female connector 26 about which it is adapted to be wrapped. A pair of transversely cir-cumferentially spaced severable, tearable or breakable indicator strips 40 and 42 are connected between the connecting strips 36 and 38. While two indicator strips 40and 42 are shown in the drawing one such strip is generally suficient.
The indicator 16 is shown in Fig. 4 as a unitary or single piece member and in its manufactured and flattened state. It is formed of an easily tearable paper, preferably with an adhesive (not shown) applied at least to end portions of the con-necting strips and may be applied to the entire one side of the connecting strips of the indicator. The connecting strip 36 is shown in Fig. 4 extending vertically and 20 having upper and lower ends, which ends overlap when applied to the cylindrical portion 37 of the connector 32, as shown in Fig. 3. The overlapping ends are connected together by the adhesive. The funnel connecting strip 38 is shorter than the adaptor connecting strip 36 because the circumference of the funnel at the strip mounting point is less than the circumference of the adaptor connector at portion 37. The25 connecting strip 38 is shown having an upper portion 44 extending at a slight angle, such as 8 from a vertical line, and inclined toward the connecting strip 36. Similar-ly, a lower portion 46 of connecting strip 38 connects with portion 44 and also extends at an angle, for example, 8 from a vertical line and toward the connecting strip 36.
Portions 44 and 46 connect at a point on a horizontal line intersecting the center of 30 connecting strip 36. The axially or transversely extending indicator strips 40 and 42 extend from connecting strip 36 at locations spaced from the opposite ends of strip 36 and rightwardly at an angle, for example, 8 from a horizontal line with eachinclined toward each other in the direction of strip 38. By forming the indicator strips 40 and 42 spaced from each other and parts of the indicator 16 at angles, as 35 described herein, the connecting strip 38 will be readily wrapped around the relative-1~,7 smaller circumference of the catheter connector 26 with the opposed ends thereof '3' -7 ~ ~1 f;
7~
overlapp;ng eacll ~^,tller arl(~ connectec] together by the adhesive while remaining parallel to the longitudinal a2~is ol tlle corlntctors and without crinkling While ~he connecting strip 38 has portionC; at angles Lo a vertic~LI line, depending on the relative circumferences of lhe connectorst both strips may be made straight and vertical like connecting strip 3~ and tlle tearable or breakable indicator strips 40 and 42 may be 5 made horizontal or normal lo the longer axis of the connecting strip 36.
l\Then the indicator 16 is applied to the $ube connectors 26 and 32, the indicator strips 40 and 42 will extend longitudinally or a~ially across the juncture of the connectors 26 and 32 and be diame~rically spaced from each other. Such strips will not be wrapped about or entirely conceal the juncture. After the indicator 16 10 has been applied at the juncture of the connectors 26 and 32, the entire assembly 10 may then be sterilized and packaged.
The tamper-evident ind;cator 16 may be stamped out of a suitable paper in the form shown in Fig. 4, wh;ch paper may be any suitable severable or te~able paper such as conventional wood pulp paper or the like, and may either be coated15 with a wetable-and-subsequently-hardening glue for attaching it to the tube conne~
tors 26 and 32 or it may be of a pressure sensitive adhesive of the type in which a protective sheet of material (not shown) is peeled away to present one side of the material with an adhesive that does not harden and that can be applied directly to the connectors without wetting. One side of indicator 16 may be entirely coated 20 with adhesive or only one of the overlapping ends of each of the connecting strips 36 and 38 may be adhesively coated. If desired, only the encircling connecting portions 36 and 38 may be coated with an adhesive. With the opposite ends of each of the connecting strips 36 and 38 overlapping and adhesively connected together it is not necessary that these strips be adhesively connected to both tube csnnectors 26 and 25 32. For example, where the catheter 18 is of silicone, some adhesives will not tight-ly adhere to the catheter, however, the ends of connecting strip 38 overlap and are tightly adhesively connected together so that strip 38 is tightly connected to con-nector 26. Some adhesives provide only a tackiness with silicone.
Should it be desired to disconnect the connectors 26 and 32 from each 30 other, the indicator strips 40 and 42 will readily tear or become broken. Upon tear-ing, the torn ends of the indicator strips may curl outwardly, as shown in phantom lines at 40' and 42' in Fig. 3, thereby making it obvious, even to the casual observer, that the connection has been broken. While two indicator strips or more are desir-able, one can be used. Where the connectors are completely disconnected from each 35 other, both of the indicator strips 40 and 42 will be broken while the connecting strips 36 and 38 will remain secured on the connectors 26 and 32. Even if the con-~ 7 ~
n~c~ors wer e r~connectec] af~er a disconnection, the presence of curled~ or urevenremnant tol n indicltor strips would be a clear indication that ti~e conrles~tors had been disconnec~ed.
Since the indicator strips 4D anc! 42 are relatively narrow, substanti~lly 5 less than the circumference of the connectors 26 and ~32, the jun^ture of the connectors 26 and 32~ including the dis~al side of flange 33, surfaee 34 and îu.~nel connector end ~7, can be seen between the indicatrjr strips when desired so that the indicator strips need not be transparent but can be of any desired color and still not conceal the connector junction. The proximal end 27 of the conical connector 26 provides a 10 iunction line at the juncture of connectors 26 and 32. Also, since the indicator slrips 40 and 42 are easily torn or broken, the indicator does not interfere with, hinder, or complicate the disconnection of the connectors 26 and 32.
As various changes could be made in the above construction without 15 departing from scope of the invention, it is intended that all matter contained in the above description and shown in the accompanying drawing be interpreted as illustra-tive and not in a limiting sense.
