Definitions
- This invention relates to a flexible container for materials which are normally incompatible when stored over extended periods of time. More particularly, the invention relates to a compartmented container wherein two incompatible materials can be sterilized in the flexible container and can subsequently be readily intermixed and administered in a safe and convenient manner.
- Compartmented containers to accommodate different types of materials are well known in the art. It is also well known to provide clamping devices for compartmented containers. For example, in U.S. Patent 3,985,135 a hemostat or other type of clamping device is utilized to provide clamping action to seal off a passage between two compartments in a blood bag reservoir. An enteral feeding container with apertures to accommodate a clamp to sequester a portion of the fluid contents of a container is marketed by Corpak Company of Wheeling, Illinois. In U.S. Patent 3,809,224 a slotted retention member in the form of a clamp is utilized to separate a container lengthwise into two separate portions. Clamping members are employed in U.S.
- Clamping-type devices for use in separating portions of containers which are temporarily folded are likewise disclosed in U.S. Patents 2,663,298; 2,756,874; 3,077,262; 3,082,867; 3,462,070 : 3,639,952; 3,741,381; 4,023,675 and 4,282,863.
- the procedure of combining the components at the hospital pharmacy requires special facilities, highly trained and conscientious personnel, valuable time, and hence an added burden of cost to the hospital especially in the situation where the hospital procures at least one of the components in bulk form and batch processes a multiple number of containers at once.
- the prior art does not provide a mixing type multi-compartment container for intravenous solution which can be readily sterilized yet activated in a desired manner. This is due to the fact that there are inherent deficiencies in the prior art containers that either prevent them from being produced economically, fail to consistently function as desired or neglect to meet all end-user requirements.
- Other advantages are a flexible intravenous solution container containing parenteral intravenous products to be intermixed and subsequently administered; a multi-compartment container wherein by means of opening a passageway between two compartments the contents of the two compartments can be intermixed in a controlled manner; a multi-compartment container that is simple in design and able to be mass produced using existing technology, commonly used fabrication equipment and applicable to a wide range of materials; a container which provides a method of intermixing at least two I.V. solutions, so that when they are combined, maintenance of sterility is assured; and a method of combining two separated components for an admixture solution that is not time consuming, does not require special facilities, or highly trained personnel to activate.

- a clamp member including a clamping portion has at least an arm portion with the arm portion adapted to be positioned over the walls defining the passageway to temporarily seal the contents of the compartments from each other.
- At least two apertures are spaced from the passageway with the apertures constructed and arranged to accept portions of the clamping member therethrough.
- the clamping member is defined by two opposing arm portions joined by a hinging portion and frictional engaging but release portions located opposite the hinging portion.

- the container body member is fabricated from two separate sheets of thermoplastic material. The apertures are spaced in opposing directions from the passageway and in the intermediate seal portion.
- the intermediate passageway is positioned adjacent the periphery of the container body member and in another it is centrally positioned.
- the flexible compartmented container generally 10 includes a tubular body section 11 having a front wall 15 which at one end terminates in an end wall 17 and another end wall 16 at the opposing end.
- Extending from end wall 16 is hanger section 20 having an aperture 23 for engagement with the usual supporting hook (not shown).
- Extending through opposing end walls 16 and 17 are tubular ports 25, 26 and 27.
- Tubular port 26 includes an outer tubular member 34 with flange 37 and an outer portion 29 for receiving inner tubular member 33 with flange 36.
- Reseal cap 40 is placed over the end of tubular member 33.
- ports 25 and 27 which also include outer tubular members 28 and 31 to which are secured inner tubular members 32 with flanges 35 therebetween.
- a protective cap 41 closes port 25 while a reseal cap 40 is placed on port 27.
- container 10 includes an intermediate section 45 formed by opposing seal portions 46 and 47 having apertures 50 and 51 therein.
- front wall 15 and back wall 21 are left unsealed in the central area designated by the numeral 53 so as to provide a passageway between upper compartment 38 and lower compartment 39.
- a clamp member 60 is described for use in closing passageway 53 by compressing opposing front 15 and back wall 21 together. This is effected when portions of the clamp 60 are fitted through apertures 50 and 51 which is best seen in FIGURE 5.
- Clamp 60 includes arm portions 61 and 62 with a hinge portion 63 between the leg portions and another hinged portion 64 attaching latch head 66.
- Flange 69 extends from an arm portion 62 as does an undercut 68 to provide engagement of undercut 65 and flange 67 of latch head 66.

- the same or similar parts are indicated by similar numbers except that they are in the "100" or "200” series. Only the different components or features are discussed as the common elements and features will be obvious.
- Concerning container 110 it differs from container 10 in that the intermediate section 145 with the opposing and spaced apart sealed portions 146 and 147 does not include apertures or holes such as indicated at 50 and 51 for container 10. Instead, slits 142 and 143 are provided in sealed portions 146 and 147 with passageway 153 therebetween. Another distinction is in sealed portions 145 and 147 having curved wall sections such as indicated at 112 and 113.
- passageway 153 will be closed by means of clamp 160 portions of which will be inserted through slits 142 and 143.

- apertures 250 and 251 are employed similar to container 10 but sealed portion 246 is different in that it is in the form of an elongated projection with a slanted wall 214 extending over more than one-half the width of the container so as to result in passageway 253 being offset from the center in conjunction with opposing sealed portion 247.
- apertures 250 and 251 are spaced an appropriate distance apart to accommodate the clamp member 260 so that flange 267 will be accommodated through aperture 250 and hinge portion 263 will be accommodated through aperture 251.

- the usual bag trimmers will be employed to sever the formed containers from the sealed sheet material.
- compartmented container 10 The filling and using of the compartmented containers 10, 110 and 210 are substantially the same. Accordingly, only compartmented container 10 will be described and those particular features of containers 110 and 210 where they are different.
- Clamp 60 will be placed in intermediate section 45 by inserting arm portion 62 through either aperture 50 or 51 and then aligning latch head 66 and undercut 68 on opposing sides of the other aperture.
- Flange 69 will be engaged by latch head 66 as to assume a clamping action as seen in FIGURE 5. This will then press front wall 15 against back wall 21 to close off passageway 53.

Abstract
5 A compartmented and collapsible container for sterile components which has at least two separate compartments for different components, yet will permit the intermixing of the components upon the release of a clamping member engaging an intermediate passageway which interconnects the compartments. The compartmented container is specifically constructed for use with two solutions which are normally incompatible over an extended period of time when mixed. The container herein described permits the two incompatible solutions to be sterilized in a disposable, flexible container. At the time of usage, the two materials can be readily intermixed in the same container and administered therefrom, such as with the usual intravenous administation equipment. An important feature of the container is a clamp member which can seal the interconnecting passageway in the container in a unique manner as well as a container with apertures to accommodate the clamp both during its operative and inoperative modes.
Description
- This invention relates to a flexible container for materials which are normally incompatible when stored over extended periods of time. More particularly, the invention relates to a compartmented container wherein two incompatible materials can be sterilized in the flexible container and can subsequently be readily intermixed and administered in a safe and convenient manner.
- Compartmented containers to accommodate different types of materials are well known in the art. It is also well known to provide clamping devices for compartmented containers. For example, in U.S. Patent 3,985,135 a hemostat or other type of clamping device is utilized to provide clamping action to seal off a passage between two compartments in a blood bag reservoir. An enteral feeding container with apertures to accommodate a clamp to sequester a portion of the fluid contents of a container is marketed by Corpak Company of Wheeling, Illinois. In U.S. Patent 3,809,224 a slotted retention member in the form of a clamp is utilized to separate a container lengthwise into two separate portions. Clamping members are employed in U.S. Patent 3,257,072 at the ends of heat seals in a flexible container for blood storage to provide temporary blockage between several compartments. Clamping-type devices for use in separating portions of containers which are temporarily folded are likewise disclosed in U.S. Patents 2,663,298; 2,756,874; 3,077,262; 3,082,867; 3,462,070: 3,639,952; 3,741,381; 4,023,675 and 4,282,863.
- In the field of intravenous therapy, such as nutritionals, it is common practice to combine at least two aqueous based solutions such as dextrose and amino acids, and deliver them to the patient in one common infusion. Due to chemical reactivity in the autoclave sterilization process or to degradation of the components over extended durations of time when mixed together, it has been necessary for the manufacturer to package the components separately. Historically, combination of the components occurs near time of use at a central hospital pharmacy. This can be a potentially hazardous procedure based on the technique used if the components of the container are exposed even briefly to the outside atmosphere. The procedure of combining the components at the hospital pharmacy requires special facilities, highly trained and conscientious personnel, valuable time, and hence an added burden of cost to the hospital especially in the situation where the hospital procures at least one of the components in bulk form and batch processes a multiple number of containers at once.
- The prior art does not provide a mixing type multi-compartment container for intravenous solution which can be readily sterilized yet activated in a desired manner. This is due to the fact that there are inherent deficiencies in the prior art containers that either prevent them from being produced economically, fail to consistently function as desired or neglect to meet all end-user requirements.
- It is an advantage of the present invention to provide a package or container separated into two compartments containing two components that would be intermixed at the time of use by means of opening a clamp member to allow the separated components to completely intermix with each other. Other advantages are a flexible intravenous solution container containing parenteral intravenous products to be intermixed and subsequently administered; a multi-compartment container wherein by means of opening a passageway between two compartments the contents of the two compartments can be intermixed in a controlled manner; a multi-compartment container that is simple in design and able to be mass produced using existing technology, commonly used fabrication equipment and applicable to a wide range of materials; a container which provides a method of intermixing at least two I.V. solutions, so that when they are combined, maintenance of sterility is assured; and a method of combining two separated components for an admixture solution that is not time consuming, does not require special facilities, or highly trained personnel to activate.
- The foregoing advantages are accomplished and the shortcomings of the prior art are overcome by the compartmented flexible container of this invention for at least two different fluids wherein the fluids can be intermixed inside the container through the release of a clamping member opening a passageway between the compartments in the container. Two spaced-apart opposing walls formed from a plastic resinous material provide a body section with an intermediate section constructed with respect to the body member and the opposing walls to separate the inside of the body member into two separate compartments as well as to define a passageway between the compartments. A clamp member including a clamping portion has at least an arm portion with the arm portion adapted to be positioned over the walls defining the passageway to temporarily seal the contents of the compartments from each other. At least two apertures are spaced from the passageway with the apertures constructed and arranged to accept portions of the clamping member therethrough. When it is desired to intermix the contents of the container in the two separated compartments all that is required is to release the clamping portion of the clamp member from the walls defining the passageway whereby the contents of the compartments will flow through the passageway and be intermixed.
- In a preferred manner, the clamping member is defined by two opposing arm portions joined by a hinging portion and frictional engaging but release portions located opposite the hinging portion. Also preferably, the intermediate section is formed from seals having an aperture in each seal with one of the apertures adapted to receive the hinging portion of the clamp and the other frictional engaging portion. Also in the preferred manner, the container body member is fabricated from two separate sheets of thermoplastic material. The apertures are spaced in opposing directions from the passageway and in the intermediate seal portion.
- In one embodiment of the invention the intermediate passageway is positioned adjacent the periphery of the container body member and in another it is centrally positioned.
- A better understanding of the compartmented flexible container of this invention will be had by reference to the following description taken together with accompanying drawings, wherein:
- FIGURE 1 is a view in side elevation showing the container of this invention prior to its being filled and without the intermediate clamping member.
- FIGURE 2 is a view similar to FIGURE 1 except showing fluid materials in the two separated compartments of the container and with the intermediate clamping member secured thereto.

- FIGURE 9 is a top plan view of another clamp member operable with the containers of this invention.
- FIGURE 10 is a partial view of the container illustrated in FIGURE 6 showing the compartment partially filled with different solutions. a
- Referring to FIGURE 1 of the drawing, the flexible compartmented container generally 10 includes a tubular body section 11 having a
front wall 15 which at one end terminates in anend wall 17 and anotherend wall 16 at the opposing end. Extending fromend wall 16 ishanger section 20 having anaperture 23 for engagement with the usual supporting hook (not shown). Extending throughopposing end walls tubular ports Tubular port 26 includes an outertubular member 34 withflange 37 and anouter portion 29 for receiving innertubular member 33 with flange 36. Resealcap 40 is placed over the end oftubular member 33. Extending throughend wall 17 areports tubular members tubular members 32 withflanges 35 therebetween. A protective cap 41 closesport 25 while areseal cap 40 is placed onport 27. It will be noted that container 10 includes anintermediate section 45 formed by opposingseal portions apertures front wall 15 andback wall 21 are left unsealed in the central area designated by thenumeral 53 so as to provide a passageway betweenupper compartment 38 andlower compartment 39. - As shown in FIGURES 4 and 5 a
clamp member 60 is described for use inclosing passageway 53 by compressing opposingfront 15 andback wall 21 together. This is effected when portions of theclamp 60 are fitted throughapertures Clamp 60 includesarm portions hinge portion 63 between the leg portions and another hingedportion 64 attachinglatch head 66.Flange 69 extends from anarm portion 62 as does anundercut 68 to provide engagement of undercut 65 andflange 67 oflatch head 66. Two optionalopposing pads 70 and 71 are positioned onarm portions Guide surfaces latch head 66 andflange 69. As indicated in FIGURES 2 and 3, asolution 80 such as an amino acid is placed incompartment 38 and a different solution such as dextrose is placed incompartment 39. They will be sealed from intermixing with each other by means ofclamp 60 engagingunsealed walls passageway area 53. - FIGURES 6 and 7 illustrate other embodiments of the invention which are referred generally by
reference numerals container 110, it differs from container 10 in that theintermediate section 145 with the opposing and spaced apart sealedportions portions passageway 153 therebetween. Another distinction is in sealedportions compartment 138 in the direction ofpassageway 153. As indicated in conjunction with FIGURE 10,passageway 153 will be closed by means ofclamp 160 portions of which will be inserted throughslits Clamp 160 will be closed whenend portion 169 is engaged byflange 167 and undercut 165 so thatpads - Concerning FIGURES 7 and 8, it will be seen that the major difference between
containers intermediate section 245. In this instance,apertures portion 246 is different in that it is in the form of an elongated projection with aslanted wall 214 extending over more than one-half the width of the container so as to result inpassageway 253 being offset from the center in conjunction with opposing sealedportion 247. As is true of the previous embodiments,apertures clamp member 260 so thatflange 267 will be accommodated throughaperture 250 and hinge portion 263 will be accommodated throughaperture 251. In this position,flange 267 will be accommodated in undercut 268 witharm portions back walls passageway 253. -
Containers side walls 18 and 19 as well asend walls slits tubular members ports - The filling and using of the
compartmented containers containers Clamp 60 will be placed inintermediate section 45 by insertingarm portion 62 through eitheraperture latch head 66 and undercut 68 on opposing sides of the other aperture.Flange 69 will be engaged bylatch head 66 as to assume a clamping action as seen in FIGURE 5. This will then pressfront wall 15 againstback wall 21 to close offpassageway 53.Compartments tubular members inner tubular member 33 withcap 40 prepositioned thereon will be solvent bonded to outertubular portion 29 and similarly innertubular member 32 withcaps 40 and 41 positioned thereon will be solvent bonded to outertubular members - In a preferred manner, dextrose solution can be placed in
compartment 39 and nutritional materials such as amino acid incompartment 38. The partially filled container will then be provided with an overwrap to environmentally protect from any external foreign contaminants, moisture loss, gas permeation, etc. and sterilized such as by autoclave sterilization. Further, depending upon sterilization cycle of each material, if the cycles are different, one compartment can be filled and sterilized and then the other compartment filled and sterilized. The container of this invention readily lends itself to this procedure. - When it is desired to utilize the container 10 with solutions such as 80 and 81 in their
respective compartments disengagement clamp 60 such as by unlatchinglatch head 66 from undercut 68. This will openpassageway 53 and allow the contents of the solution to intermix with all of the solution material then being placed incompartment 39. In the instance where a fluid material such as a powdered antibiotic material were to be placed incompartment 38, resealcap 40 andport 26 will afford insertion of a needle of a hypodermic syringe so as to inject sterile water or other diluent intocompartment 38 whereupon subsequent mixing such as by shaking the container will afford thorough intermixing. Of course, in this instance theclamp 60 will be in the closed position and subsequently opened as previously described to allow the antibiotic solution to then mix with the contents ofcompartment 39. After thorough intermixing, the container can be supported from the usual hook such as by placing throughaperture 23 and the protective cap then removed foradministration port 25. The usual administration pin of an I.V. set will then be applied toport 25 and the mixed materials administered in the usual manner. - The use of
containers upper compartments passageways curved walls slanted wall 214. The offsetopening 253 allows easier access and manipulation of clamp, both in assembly and removal. - The preferred plastic resin for plastic sheet material forming the various
compartmented containers clamps clamp 60 andpads clamp 160 are utilized. This can- be eliminated as can be seen inclamp 260 and still afford the requisite temporary sealing of passageway such as 253. While two ports such as 25 and 27 are indicated in communication withlower compartment 39 one single port with reseal capabilities could serve as additive and administration port or where an additive material is not desired to be placed in thecompartment 39, a single administration port would be sufficient. - While the various containers have been described for use with an intravenous nutritional product, other applications for the container are numerous in the related medical field such as enteral feeding, continuous ambulatory peritoneal dialysis, chemotherapy, etc. Further, the compartmented container of this invention fulfills the need for a container in industries apart from the medical field such as food and beverage, cosmetics, adhesives, etc. While the containers of this invention have been described for use with a clamp and passageway to form a dual compartment container, it is obvious that several of the clamps and passageways could be provided in a container to form a multiplicity of compartments, the contents of which can be intermixed by opening the various clamp members in any preferred sequence.
- It will thus be seen that through the present invention there is now provided a flexible container for any incompatible materials which is easily fabricated and readily utilized to mix the compartmented materials. The container with the clamp member can be activated with a minimum amount of effort yet provide a container system which will not be activated unintentionally. The container of this invention can be molded in various configurations to be adapted to numerous types of incompatible materials. The materials when placed in the various compartments of the container are readily sterilized and will remain sterile after the desired intermixing. All of the foregoing is accomplished in the container which can be fabricated in the manner which does not result in substantial increased cost and accordingly, in a container system which is disposable.
- The foregoing invention can now be practiced by those skilled in the art.
