    Field of the Invention
    [001] This disclosure concerns a coupling that allows separation for use with medical fluids. In particular, this disclosure concerns a coupling that allows separation that uses valves to seal both ends of a coupling when the coupling is disconnected. Background
    [002] Supply set couplings are currently used in supply tubes in order to connect a supply source with a supply tube. Power pack couplings typically include a male adapter that matches a female receptacle. Many of such couplings do not include integrated automatic shut-off valves. When a coupling is accidentally disconnected, such as when incidental voltage is applied to the supply system, the tube supply can continue to flow uninterruptedly from the supply source. In addition, contents of the patient's gastrointestinal tract can flow in reverse uninterruptedly from the patient. This results in several problems, such as loss of tube feeding, loss of medication, loss of time to obtain the necessary daily amount of calories for a patient, compromised patient health, cleanliness, poor sleep due to humidity and hunger, and potentially aspiration by the patient of the spilled tube feed.
    [003] Some supply systems include alarms that signal when a power supply is "flowing freely". However, these alarm systems work only if the power supply becomes disconnected from the pump, and not if the coupling becomes disconnected. Some manufacturers have tried to prevent the power pack coupling from becoming disconnected. These devices can cause the feeding tube to be dislodged entirely from the patient, resulting in additional problems. Summary of the Invention

    [025] An example 10 coupling device is a coupling that allows automatic locking separation for a medical fluid delivery system 12. The example 10 coupling device can be used with any type of fluid delivery, such as delivery of food, delivery of medication, or something like that. For example, coupling 10 can be used for intravenous and arterial lines, dialysis connections, Foley catheter connections, chest tubes, or any other type of liquid, gas or vacuum connection used for patient care. The coupling device 10 includes a female component 14 and a male component 16, with a connection that allows separation 18 provided between the two components 14, 16. Housings, couplings or other parts, as described with further details below, can be color-coded for different uses and the dimensions of the connections that allow separation can be varied in order to prevent wrong connections. Although the following description is directed primarily to the context of the supply system 12, it should be readily recognized that the description is applicable to other systems, the invention is not limited to a particular application.
    [026] The example coupling 10 has the ability to automatically eliminate flow from both free ends of the coupling 10 when it becomes disconnected. Flow from the tube power supply source 20 is eliminated when coupling 10 becomes disconnected. In addition, reverse flow from the patient's gastrointestinal tract 24 is eliminated. This automatic blocking will act as an occlusion for the feed pump 22. Since almost all feed pumps 22 have an occlusion sensor, it will alert a healthcare professional that there is a problem with the feeding system 12. Because of if the flow is stopped completely through system 12, the health professional will know exactly how much food was and was not delivered. Furthermore, because reverse flow from the patient's system 24 is prevented, this helps to maintain a patient's feeding schedule and prevents dirt from the clothes, bed and room.
    [027] The example coupling device 10 is inexpensive, disposable, small, easy to clean and quick to install. It is easy to use and matched couplings disconnect at forces below those that would dislodge a patient's feeding tube. The construction of the couplings 10 allows for easy sterilization. Flow path 26 through coupling 10 is a straight path, which allows coupling device 10 to be used with thicker fluids and prevents hemolysis of blood cells if blood is used as the transfer medium. Furthermore, at least one example of coupling 10 does not include any materials that could decompose or corrode with repeated uses and washes, such as springs.
    [028] The amount of tension required to separate coupling 10 can be varied based on the application. For example, if coupling device 10 is used to deliver medication via an IV, the force required to remove the IV may be less than the force required to remove a feeding tube from a patient's gastrointestinal tract.
    [029] The example coupling device 10 includes a male component 16, a female component 14 and the two valves 28, 30. A first valve 28 is positioned at one end of the male component 16 and a second valve 30 is positioned at the end of the female component 14. Valves 28, 30 are non-mechanical resilient self-closing valves. Examples of valves that are discussed in this document are slit valves and duckbill valves. Any other type of non-mechanical valve can also be used.
    [030] Figure 1 represents the example coupling device 10 installed in a supply system 12. Coupling 10 is positioned between the supply pump 22 and patient 24. An example coupling device 10 that is used for this purpose can be about two inches (5.08 centimeters) long. Other lengths and sizes can also be used. The size of the coupling device 10 may depend in part on the application, among other factors.
    [031] Figures 2 and 3 show the female component 14 of the example coupling 10. As shown in figure 2, the female component 14 includes a valve 30 which is housed in a valve housing 32. A female receptacle addition 34 it can be attached to valve housing 32 via any known devices, such as by means of adhesive or welding, among other known fixation techniques. One type of welding that can be used to join these and other parts of the coupling 10 is ultrasonic welding. The addition of female receptacle 34 can be molded of rigid plastic. The valve housing 32 can be formed of a polycarbonate or a copolyester and can be transparent or opaque. The sample valve housing 32 shown in figures 2 and 3 is transparent and the female receptacle insert 34 is opaque. The female receptacle insert 34 and the valve housing / valve housing 30, 32 are coupled together to provide a female component 14. Other types of materials can also be used for the various parts.
    [032] In figures 2 and 3, a silicone slit valve 38 is shown positioned inside the valve housing 32. The slit valve 38 is positioned axially inside the housing 32. The addition of the female receptacle 34 rests on the opening of the slit valve 38. Slit valve 38 is shown to be flush with the opening for valve housing 32. Slit valve 38 is normally in a closed position, but can be opened by pressing an object against slit 40 in the slit valve 38. When the object is inserted into the valve, slit valve 38 automatically seals itself around the object. Furthermore, when the object is removed, the slit valve 38 automatically seals itself. The slit valve 38 can be made of silicone or other materials. When an object is inserted into slit valve 38, the valve is compressed and this allows slit 40 to be opened. The compressed silicone acts like a spring. When the object is removed, the compressed silicone returns by spring action to its loosened state and the slot 40 closes automatically.
    [033] The female receptacle addition 34 has an opening in communication with the opening of the slit valve 38 or valve 30 and serves as a guide for an object to be inserted into the slit valve 38. The addition of the female receptacle 34 also it has an adapter 42 at one end for coupling with another part in a mode that allows for separation. In particular, adapter 42 includes a rib or lip 44 that forms a male connector that can be joined to a female receptacle 66. The rib or lip 44 extends around the opening. The rib or lip 44 may have a beveled or rounded edge to aid insertion into a corresponding female connector.
    [034] Figures 4 and 5 represent parts of the male component 16 of the example coupling 10. The male component 16 includes a male component housing 46 which is shown formed in two parts. The two parts can be joined together by means of welding, adhesive, force fitting, pressure fitting or other device. A slit valve 28 and valve housing 48, such as those shown in figure 2, are coupled to one end of the male component 16 and a tube 50 of a supply system 12 can be coupled to the end of the valve housing 48. Valve housing 48 is coupled by means of any known devices, such as welding, adhesive or threads. Valve housing 48 can be made transparent or opaque and can be made of a polycarbonate, a copolyester or another material.
    [035] A floating double male adapter 52 is elongated and has a central hole 54 that extends between the ends of it in a single channel. The double male adapter 52 is positioned and captured within the male component housing 46 and has opposite end sections 56, 58 and a central section 60. Each section is separated by protrusions extending externally in the form of radially extending shoulders 62 outward around the outer surface of the double male adapter 52. The lugs 62 prevent the tips at each end 56, 58 of the double male adapter 52 from extending too deeply into the valves 28, 30. If the ends 56, 58 meet penetrate very deeply into valves 28, 30, valves 28, 30 are unable to properly act as a spring to expel adapter 52 during disconnection. The lugs 62 on the double male adapter 52 also match the stop 64 within the male component housing 46 to ensure that each end of the double male adapter 52 activates each valve 28, 30 equally.
    [036] The double male adapter 52 is positioned inside the male component housing 46 in such a way that a first end 56 of the adapter 52 is in communication with the first valve 28 of the male component 16. The male component housing 46 has the grooves 64 to accept one of the shoulders 62 of the double male adapter 52 in order to secure the adapter 52 inside the housing 46. The double male adapter 52 is movable longitudinally within the male component 16. When the double male adapter 52 is pressed into the valve 28, the first end of the adapter enters the slot in the valve and provides a straight fluid flow path 26 (shown more clearly in Figure 9) between the interior of the male adapter 52 and an inner chamber of valve housing 48. Other passages not straight lines could be used, if desired. The male component 16 of the coupling 10 is shown in figure 5.
    [037] Figure 11 shows the double male adapter 52 positioned inside a slit valve 38. The double male adapter 52 has a hole 54 creating a straight flow path 26 through the center of it and the slit valve 38 forms a watertight seal around the end of the double male adapter 52.
    [038] The male component housing 46 consists of two parts that are joined together with the double male adapter 52 fitted within them. This prevents the double male adapter 52 from becoming detached from the assembly during normal use. Female luer lock threads are positioned at the valve end of the male component housing 46 (shown in figure 4). These threads allow the healthcare professional to easily fix this assembly or remove the functional end assembly from a 28 valve. Other types of fixation mechanisms can be used for the connection, either alone or in combination. The advantage of this assembly is that it is removable for cleaning purposes. At the other end of the male component housing 46 is the female receptacle 66 of the snap-in feature that allows separation. The design of these fittings can be changed to suit different separation forces. The design of the current plug-in feature enables the two ends of the coupling 10 to rotate freely without interrupting flow. This helps to prevent winding of the supply line 50.
    [039] As shown in figures 2 and 3, the female receptacle addition 34 is attached to the functional end of the female component valve housing 32. The female component 14 contains the male fitting 44 of the fitting feature which allows for separation that matches with the male component housing 46 via the rib / lip 44. This snap feature retains the two ends of the coupling 10 together. Once sufficient tensile force is placed on the coupling 10 to overcome the snapping force that allows separation, the silicone valves 28, 30 will act as springs to expel the double male adapter 52. This will interrupt flow from both free ends coupling 10.
    [040] Figure 6 shows a complete coupling device 10, where the male and female components 16, 14 are joined together. The valve housings 32, 48 are positioned at the ends of the coupling device 10 and the outer ends of the valve housings 32, 48 are used for coupling to the pipeline 50 in a supply system 12, or in another system. The valve housings 32, 48 can be transparent and the male component housing 46 and the addition of female receptacle 34 can be opaque, although any of the components can be opaque or transparent, if desired.
    [041] Figures 7-10 represent how the coupling device 10 of figures 2-6 is assembled. They also show the straight flow path 26 that is created through the center of the coupling device 10. Figure 7 shows the first valve 28 being coupled to the end of the male component 16 and the second valve 30 coupled to the addition of the female receptacle 34. The double male adapter 52 is positioned within the male component housing 46 and a shoulder 62 on the male adapter 52 is captured within the male component housing 46 behind an internally extending rib 64. The internally extending rib 64 holds the male adapter 52 in place within the male component housing 46. The opposite end 58 of the male adapter 52 is shown aligned with the female receptacle 34 on the female component 14.
    [042] Figure 8 shows the second end 58 of the male adapter 52 being pressed against and inserted into the slit valve 30 of the female component 14. The end 58 of the male adapter 52 enters the slit 40 and is pushed fully through the slit 40 until that the opening of the adapter 52 is positioned inside a cavity within the valve housing 32. This allows fluid to flow through the second valve 30 and through the double male adapter 52 in a straight flow path.
    [043] Figure 9 represents the first end 56 of the male adapter 52 inserted in the first valve 28 and through it. As with the second end 58 of the male adapter 52, the first end 56 is inserted into slot 40 in the first valve 28 until the first end 56 of the male adapter 52 enters the cavity within the valve housing 48. In this position, the device coupling 10 is not yet completely closed, however flow path 26 has been established.
    [044] Figure 10 represents the male and female components 16, 14 coupled together with the fittings 42, 66 at the end of the male component 16 and the female component 14 together. The male component 16 includes an internally defined rib 68 at the end thereof and the female component 14 includes an externally defined rib 44 at the end thereof. The flexibility of the parts allows a user to press them together until they click into place. This connection can be loosened with the application of sufficient force. Other types of connections can also be used, as known to those skilled in the art.
    [045] Figures 12-20 represent an example 10 alternative coupling device that is similar to the device disclosed earlier, but includes a duckbill valve 70 instead of a slit valve 38. A duckbill valve 70 is similar to a slit valve in which it accepts an object through the opening in the valve and seals itself around the object. When the object is removed from the valve, the valve is closed automatically by itself.
    [046] Referring to figure 12, a female component 14 of the coupling device 10 is shown. The female component 14 includes a housing 72 that is formed of two parts that match together in any known manner, such as by means of adhesive or welding. Housing 72 may be made of rigid molded plastic or other material. The female component housing 72 includes the internally arranged ribs 74 to accept a duckbill valve 70 and a channel 76 to accept part of the male adapter 52. Furthermore, the female component 14 is provided with a channel 78 at a free end for fixing to piping 50. The duckbill valve 70 can be made of molded silicone or other materials.
    [047] Figure 13 shows the female component 14 in an assembled configuration. The duckbill valve 70 is positioned inside the housing 72 and an opening 80 is provided in the female component 14 adjacent to the valve opening. The female component 14 has a socket 42 for coupling to a male component 16 in a mode that allows separation, similar to that discussed previously in connection with figures 2-11.
    [048] Figures 14 and 15 represent a male component 16 of the alternative coupling of example 10. Male component 16 includes a male component housing 46 which is formed of two halves which are joined together in any conventional manner. Housing 46 is made of rigid molded plastic or other materials. The male component housing 46 includes a radially defined internal rib 74 to accept a duckbill valve 70 inside the housing 46. The male component housing 46 also includes a chamber 82 that houses a spring 84 which is used to predispose an adapter double male 52 to an uninstalled position. The double male adapter 52 shown is similar to that previously discussed and includes two radially extending shoulders 62 and an elongated body with a passage extending the entire length thereof.
    [049] Figure 15 shows the double male adapter 52 and the duckbill valve 70 installed inside the male component housing 46. The first end 56 of the double male adapter 52 is associated with the duckbill valve 70 and the second end 58 of adapter 52 is shown as free, but will be used for joining with the female component 14 of figures 12/13. The first shoulder 62 on the double male adapter 52 is positioned behind an internal rib 64 of the housing 46 in order to hold the adapter 52 in place within the housing 46.
    [050] Figures 16-19 depict the marriage of male and female components 16, 14 of the alternate coupling device of example 10. Figures 16-17 show male and female components 16, 14 before insertion of the double male adapter 52 on the female component 14. The duckbill valves 70 are positioned inside the male and female components 16, 14 and the spring 84 is positioned around the first end 56 of the double male adapter 52. The male component 16 has a female receptacle 66 on the opening it for coupling to a male adapter 42 defined at the end of the female component 14 in a mode that allows separation. The female component 14 has an externally extending rib 44 to mate with the male component 16. Although a plug connection is shown, other connections, such as screw threads, snap fitting or the like, can also be used.
    [051] Figures 18-19 depict male and female components 16, 14 in an entirely matched configuration. As shown, the ends 56, 58 of the double male adapter 52 extend through both duckbill valves 70 in order to provide a straight flow path 26 through the coupling 10. The tubing 50 can be coupled to either coupling end 10. The male and female fittings 42, 66 are coupled together in a manner that allows separation in such a way that they can be separated by applying sufficient force to the coupling 10. The separating force can be varied by varying the shape and size of the inserts 42, 66, for example. When the coupling 10 is broken, the female component 14 is separated from the male component 16 and the second end 58 of the double male adapter 52 is removed from the duckbill valve 70 of the female component 14. Because of its design, the nozzle valve of duck 70 closes automatically when the male adapter 52 is removed from the female component valve 30. Then, because the second end 58 of the double male adapter 52 is released, the spring 84 pushes against the shoulder 62 on the double male adapter 52 and o forces out the male component valve 28. This removes the first end 56 of the double male adapter 52 from inside the duckbill valve 70 in the male component 16 and the duckbill valve 70 closes automatically. Thus, as is evident, when coupling 10 is separated, both valves 28, 30 will close automatically and fluid cannot flow from the food source 20 or the patient's system 24.
    [052] Figure 20 shows the double male adapter 52 positioned inside a duckbill valve 70. The double male adapter 52 has a straight flow path 26 through the center of it and the duckbill valve 70 forms a watertight seal around the end of the double male adapter 52.
    [053] The coupling apparatus comprises a first component including a first non-mechanical valve, a second component including a second non-mechanical valve, and a third component having a first end for coupling with the first valve and a second end for coupling with the second valve. The third component has an elongated bore in such a way that, when the first end is coupled to the first valve and the second end is coupled to the second valve, a passage is defined through it. The passage may have a straight flow path.
    [054] The third component can include a housing having a first half and a second half and a double male adapter positioned within the housing. The first component includes a first housing and the first valve, and the second component includes a second housing and the second valve. At least one of the first and second housings has a socket for securely coupling axially with the third component housing.
    [055] At least one of the first and second components includes a female receptacle to match the double male adapter. The first and second valves are resilient self-sealing elements. Each of the resilient sealing elements has a slit at one end thereof that extends through the resilient element and allows the ends of the third component to penetrate the respective sealing element. The first and second valves are duckbill valves or slit valves.
    [056] The double male adapter is elongated and the first end is to be inserted into and through the first valve. The second end of the double male adapter is to be inserted into and through the second valve. The double male adapter includes a first protrusion and a second protrusion on an external surface of the same. The protrusions are for matching surfaces defined at least in the third component housing to hold at least part of the double male adapter within the third component housing. The double male adapter is movable in the third component housing.
    [057] The third component housing includes a locking surface and the housing of the adjoining component has a locking surface. The interlocking surfaces, when joined together, can be detached from each other to release the third component from the adjoining component. The first component can be attached to the third component with welding, adhesive or a fitting. The second component can be fastened to the third component.
    [058] The third component includes a third housing having a first half and a second half and a double male adapter positioned within the third housing. The first component is integral with the third component, and the second component includes a second housing having a first half and a second half and the second valve. The second housing has a socket for fixedly axially coupling with the third component housing. The fitting is a fitting that can be separated, and the first and second valves are duckbill valves. A spiral spring is positioned inside the third component housing and predisposes the double male adapter to an uninstalled position.
    [059] In another example, a coupling device comprises a first component having a first non-mechanical valve, a second component having a second non-mechanical valve, and a third component having a first end to couple with the first valve and a second end to couple with the second valve to establish fluid flow through it. The third component is separable from one or more of the first and second components by applying sufficient force. When one or both of the first and second components are separated from the third component, the first and second valves close automatically.
    [060] Fluid flow through it can be along a centrally arranged axial flow path. The first and second valves are duckbill valves or slit valves.
    [061] In another example, a component that allows self-locking separation for a medical fluid device comprises a male component that attaches to the tubing to receive a fluid and a double male adapter coupled to the male component. The double male adapter has a first end and a second end. The component that allows self-locking separation also includes a valve coupled to the male component 16 and to one end of the double male adapter. The valve is positioned between the tubing and the double male adapter.
    [062] The valve can be integral with the male component and the male component has a fitting for coupling to another part. A female component can be coupled to the male component. The female component has an opening for receiving the other end of the double male adapter and includes a second valve to match the end of the double male adapter.
    [063] The term “substantially”, if used in this document, is an estimation term.
