Geiger Assistant Examiner-Edward J. Earls Attorney-Joseph Martin Weigman ABSTRACT: The disclosure is directed to a universal dispensing package for medicaments to be dissolved in a parenteral container prior to use. A container is provided with a cap which first, has a hollow piercing device for dispensing a contained medicament into a closed system parenteral solution container, and, second, has a frustoconical shank adapted to engage the interior surface of the neck of an open system" parenteral solution container. A membrane filter may be disposed between the container and the cap. An outer sheath 1 is provided over the cap and is scaled in place.
UNIVERSAL DISPENSING DEVICE FOR INTRAVENOUS MEDICATIONS This invention is directed to a universal dispensing package for dispensing sterile medicaments and to a method for preparing injectable solutions of such medicaments by transferring the medicament from the dispensing package to a parenteral solution container under substantially aseptic conditions. The dispensing package is adapted to aseptically transfer its contents to both open system" and closed system" parenteral solution containers. .An "open system" parenteral solution container, typically glass, is one having a threaded closure which is removed in order to discharge the contents. A "closed system parenteral solution container, typically glass, is one having a fixed plug, typically rubber, which is perforated by a sharp conduit, typically a hollow plastic needle, in order to remove the contents. Another type of closed system which has recently become available is made of flexible plastic and has a plastic membrane closure which is perforated by a sharp conduit. 1 l
The method may be practiced by transferring a sterile medicament, such as a powder, a lyophilized cake or a solution, to a parenteral solution container of diluent adapted for parenteral injection, irrigation or the like, the transfer being accomplished with maximum protection to sterility.
It is common practice to add medicaments to parenteral solutions in their containers at the time the parenteral solutions are administered. The additives may be antibiotics such as sodium ampicillin, muscle relaxants, such as succinylcholine chloride, and others. The parenteral solution may be a saline solution, glucose-saline solution or other isotonic solution, such as is commonly employed for parenteral administration. Such solutions are usually administered intravenously but may be otherwise parenterally administered or may be used for irrigation.
The added medicaments are usually solutions, powders, or lyophilized cakes. Previously available means for bringing the powders or cakes into solution and for transferring the resulting solution to the bulk parenteral solution have been cumbersome and complicated and not devoid of risk to the sterility of the product contained.
There are two principal forms of containers for the parenteral solutions. More than half of the total market for intravenous fluids is supplied in closed-system containers as they are defined above, while the remainder of the market is supplied in open-type containers as defined above. There are various dispensing packages for medicaments to be used in conjunction with parenteral solution containers. Typicalpackages are described in US. Pat. Nos. 2,957,501; 2,957,609; 3,059,643, and 3,143,251. There is, however, no dispensing package available which may be used conveniently with both the closed-system and open-system parenteral solution containers with complete assurance of maintenance of sterility.
Numerous parenteral powders for reconstitution containing antibiotics and other medicaments are commercially available. A problem has been that in the manufacture of such powders, it is extremely difficult to control the particulate matter content at a satisfactory level and consequently the solutions ultimately prepared from such powders often contain substantial particulate matter counts. Commonly available antibiotics and other powdered injectable products suffer from this disadvantage. Increasingly higher standards for parenterals indicate that the amount of particulate matter should be greatly reduced.
Even in the instances of drugs marketed in the form. of solutions which may be originally packaged substantially free of particulate matter, it is well known to those skilled in.the art that the amount of particulate matter may increase substantially during the shelf life of the product as a result of contact with package components, trace drug decomposition and the like. Such solutions after the development of the particulate matter are still suitable for their intended use if the particulate matter is removed. The particulate matter may not be visible to the naked eye, and consequently the user may be unaware of its presence, and yet it might be potentially harmful. A dispensing package which overcomes this problem is described in copending application Ser. No. 742,872, filed by Howard J. Levin on July 5, I968 and entitled .Package. In that application a package utilizing a membrane filter for the removal of particulate matter is disclosed.
It is an object of the present invention to provide apparatus for the addition of medicaments to both open and closedsystem containers of intravenous parenteral mixtures which provides for the filtration of the medication added to the intravenous parenteral mixtures.
It is another object of the present invention to provide a universal dispensing package for medicaments which are to be added to parenteral solutions which may be used with powders that are not free flowing or are hygroscopic, and can be used with liquids and nonhygroscopic powders as well.
It is another object of the present invention to provide a method ofdissolving medicaments in a parenteral solution in a convenient aseptic manner and which provides control of the particulate matter contributed by the added medication.
Other and further objects of the present invention will be apparent to those skilled in the art from reading the following description taken in conjunction with the drawings, in which:
FIG. I is a sectional view of a dispensing package embodying the features of the present invention;
FIG. 2 is a partial sectional view showing the embodiment of FIG. 1 in use in conjunction with a closed-system intravenous container;
FIG. 3 is a partial sectional view showing the embodiment of FIG. I used in conjunction with an open-system intravenous container; and
FIG. 4 is a detail view of an alternate embodiment of the dispensing package of FIG. 1.
The objects of the present invention may be achieved with a medicament dispensing package which is made up of a reservoir adapted to contain the medicament, a substantially frustoconical cap containing a conduit adapted to convey the medicament from the reservoir to a parenteral solution container, and means to retain the medicament in the reservoir during storage. The frustoconical cap is shaped to have, first, a tapered shank portion adapted to engage the interior surfaces of the mouthof an open-system parenteral solution container and, second, a piercing device adapted to pierce the closure of a closed-system parenteral solution container. While the preferred embodiment utilizes a variable-volume, plastic reservoir, a fixed-volume reservoir-such as a glass or plastic bottle may also be utilized.
A preferred embodiment of the present invention is shown in FIG. I. A universal dispensing package 10 is made up ofa container, or reservoir, 12, a cap 14, a filter 16, a protective sheath 18 and a seal band 20, and contains a medicament 22. The container 12 has a neck 24 provided with threads 26. At the lower portion of the neck 24 is an external flange 28 having a series of knurls, or lugs, 30.
The cap 14 has a shank 32 which has internal threads 34 adapted to cooperate with the threads 26 of the neck 24 to provide a screw-type engagement. The outer surface 36 0f the shank 32 tapers from a proximal periphery 31 to a distal periphery 33 and generally defines a truncated cone, as shown. The outer surface 36 may have a patterned configuration such as fluting 37, defined on it to adapt it better to cooperate with the interior of the neck of an open-system parenteral solution container as described below. A transition piece 38 extends from the shank 32 and with it defines a shoulder 40. A piercing device 42 is provided at the end of the transition piece 38. The piercing device 42, the transition piece 38 and the shank 32 are hollow, and together define a conduit 44. An inner surface 46 is defined in the shank and with the upper edge seat for the filter 16.
The protective sheath l8 surrounds the entire cap 14 and is held in place by the-sealing band 20 whichmay surround the portion 25 of the container 12 defines a lower portion of the protective sheath l8 and extend from a shoulder 48 on the sheath to a point below the flange 28 and be crimped around the flange. The knurls 30 prevent rotation of the sealing band 20.
The patterned configuration on the surface 36 may take one or more of a number of forms designed to make the surface sufficiently flexible sealably to engage the inner surface 60 of an open-system parenteral solution container. To provide an effective seal the form selected should be relatively short in extension from proximal periphery 31 to distal periphery 33. The patterned configuration may be formed by lightly roughening the surface 36. The surface configuration may be formed by making a series of short discontinuous cuts on the surface, for instance in the form of X's or Ys. Other configurations are also effective. The preferred form, however, is the fluting 37 which, as is shown in the drawings, is a plurality of annular yieldable protuberances, or depressions, defined in the outer surface 36.
Whilethe preferred embodiment utilizes the filter 16 to retain the medicament 22 and for other purposes, it is to be understood that the filter may be eliminated and other means used to retain the medicaments. in FIG. 4 is shown an alternative embodiment in which a sheath 19 has a stud 50 formed in it. The stud 50 is adapted to engage the channel 44 inside the piercing device 42. The stud thus fills the end of the conduit, provides a tight seal, and retains the medicament. The filter 16 may be omitted, if desired, in such an embodiment.
The entire dispensing package may be placed in an outerwrap of plastic, metal foil, or combinations thereof or a rigid, hermetically sealed container to control the ingress of water vapor or other gases and to further assure the maintenance of sterility.
In use the sealing band 20 and the protective sheath 18 are removed. When used with a closed system intravenous con tainer as shown in FIG. 2, the piercing device 42 is inserted through a sealing member 52 and a rubber stopper 53 of the closed-system intravenous container 54. The conduit 44 provides communication between the interior of the container 54 and the contents of the dispensing package 10. Where the medicament 22 is a liquid, it is readily discharged into the container 54 by compressing the sides of the flexible container 12. The medicament 22 passes through the filter 16 where any particles are removed. The steps may be repeated to flush the container, if desired.
Where the medicament 22 is dry, the walls of the container 12 may be compressed and the tip 42 submerged in the liquid 56 by inverting the assembled system. A suitable portion of the liquid 56 may be drawn into the container 12 in order to dissolve the dry medicament. To make this possible it may be necessary to relieve any vacuum present. The reconstituted medicament solution may be discharged from the package 10 by compressing the sides of the container 12. The medicament 22 passes through the filter 16 where any particles are removed.
in FIG. 3 is shown the dispensing package 10 in position to discharge its contents into an open-system parenteral solution container 58. The outer surface 36 of the shank 32 engages the inner surface 60 of the container 58 and with it forms a tight seal. The tightness of the seal may be increased by the formation of a patterned configuration on the outer surface 36 of the shank 32 in order to develop a suitable friction seal. The medicament 22, when liquid, may be discharged directly into the container 58. Where the medicament is a solid, the package 10 and the parenteral solution container 58 may be inverted and a portion of the fluid 59 drawn into the dispensing package 10 where, with gentle agitation as necessary, it dissolves the medicament 22. The reconstituted medicament solution may be discharged by again returning the containers to the position shown in FIG. 3 and compressing the flexible sides of the container 12.
The container 12 is preferably made of polyethylene, or similar elastically recoverable material but may also be made of rigid material such as glass if desired. The cap 14 is preferably made of rigid polyethylene but may be made of any other suitable plastic or metal. The piercing device 42 is typically made of the same material as the remainder of the cap 14, but if desired may be ofa different material such as a metal or alloy. The protective sheath 18 or 19 and'stud 50 are typically plastic but may be made of rubber or other suitable materials. The seal band 20 may be made of metal or plastic, and preferably is a plastic that shrinks on drying.
The filter may be any suitable material, including sintered glass. However, membrane filters are preferred. Membrane filters are a class of thin filters composed of a porous matrix wherein the size of the pores prevents any insoluble matter larger than the pores from passing through the filter. When used for sterilization, membranes are composed of pores small enough to prevent the passage of microorganisms and thus render the solution sterile. The membrane filter is usually composed of cellulose esters such as cellulose acetate, cellu lose triacetate, cellulose nitrate, combination of cellulose acetate and nitrate, regenerated cellulose, polyethylene, nylon, Teflon, polyvinyl chloride, fluorinated vinyl, polypropylene, epoxy glass, acrylic vinyl copolymer, or the like. The membrane filters useful in the practice of the present invention customarily range in thickness from 25 to 300 microns and have a pore size range from about 0.005 micron to 10 microns, preferably from about 0.2 micron to 10 microns. The filter may assume a variety of designs and embodiments to accomplish its function. A preferred embodiment of the filter is one that resembles a plate-and-frame filter and comprises at least one membrane supported at its periphery. Filters having a pore size range of 0.005 to 10 microns are commercially available. Filters having pore sizes smaller than about 0.2 microns sterilize by removing micro-organisms. Filters having a pore size range of about 3 to ID microns are particularly useful in the preferred embodiment.
The terms and expressions which have been employed are used as terms of description and not oflimitation, and there is no intention in the use of such terms and expressions of excluding any equivalents of the features shown and described or portions thereof, but it is recognized that various modifications are possible within the scope of the invention claimed.
