Description




TECHNICAL FIELD




The present invention relates to a coupling device for coupling a vial connector to a drug vial. The invention can be implemented for aseptic preparation and handling of drugs involving a special vial connector having a cannula which is utilised for puncturing the seal of a drug vial or another drug bottle.




BACKGROUND OF THE INVENTION




When preparing drugs, intended for e.g. injection or infusion, demands are made on aseptic conditions. In order to achieve such conditions when preparing drugs, for example in hospitals and pharmacies, special safety boxes or cabinets in a clean room environment normally are utilised.




Recently, a serious problem in connection with drug preparation and other similar handling has been observed. It has been found that medical and pharmacological staff can be exposed to drugs or solvents in the ambient air while performing drug preparation. This problem is particularly serious when the preparation of e.g. cytotoxic drugs is concerned. Cytotoxic drugs have been reported to constitute a working environment problem when they escape into the environment. Antiviral drugs, antibiotics and radiopharmaceuticals are other drugs which can create working environment problems.




Therefore, it has been proposed that aseptic preparation and handling of drugs should be accomplished by means of special assemblies which are sealed against the ambient air before and during administration to a patient.




Accordingly, U.S. Pat. No. 5,766,147 discloses a device which provides for direct incorporation of a substance from a separate container, such as a drug vial, into the contents of a liquid delivery device, which has a connecter to provide communication between the device and the container, and means for closing the connection prior to dispensing the contents of the device. Furthermore, U.S. Pat. No. 5,766,147 discloses a method for permitting a substance in a container to be transferred to a liquid delivery device, and the contents of the device to be administrated to a patient.




Furthermore, WO 98/32411 discloses a luer connector comprising a luer connectable to a syringe and which extends to a sharpened end capable of being driven through a puncturable vial closure to thereby puncture the closure, a luer support which is mountable on a vial and which initially supports the luer in a first position in which the sharpened end of the conduit is pointed towards the closure. The luer connector further comprises a luer driver such that movement of the driver relative to the support causes the luer to be driven so that the sharpened end punctures the closure and enters the vial. The luer connector facilitates connection of a hypodermic syringe to the vial.




The patent publication FR 2 714 824 discloses a vial device comprising an external cover exhibiting a first, open end and a second, closed end provided with a passage for a liquid. The cover comprises perforating means in which the perforating end projects through the passage into the cover. The perforating means exhibits an internal channel which extends the passage. Thereby, a vial exhibits a body having a a first end provided with puncturable membrane and a second end sealed by a piston slidingly mounted within the body of the vial. When in a storage position, the vial is coupled to the cover and is arranged to be pressed into the cover in such a way that the perforating means punctures the deformable membrane, with sealing means between the cover and the body of the vial.




Many drugs are provided in a dry form in order to achieve a longer shelf life, e.g. so-called lyophilized drugs. Such drugs have to be prepared by means of adding a suitable solvent before being administrated to a patient. This is usually accomplished by means of a special connector assembly or the like for enabling attachment of the vial to a source of solvent to reconstitute the dry drug.




Accordingly, EP 0 829 250 A2 discloses a connector assembly for efficient flow of liquid into and/or out of a vial, such as a vial containing a lyophilized drug. The connector assembly features a collar which is mountable to the rim of the vial in a locked position and thereafter removable by an end-user when disposal of the device is desired.




Thus, aseptic preparation and handling of drugs often involve that a special connector having a cannula is utilized for puncturing the seal or closure of a drug vial or drug bottle. The previously known methods for coupling such connectors to a vial and puncturing the seal of the vial are associated with certain problems.




For instance, it has been found that the cannula of the vial connector often may puncture the vial seal in an undesirable way, e.g. so that the cannula creates a larger perforation in the vial seal than necessary, and thereby increases the risk that cytotoxic drugs or the like escape into the working environment.




In cases where the previously known vial connectors are pressed down manually around the neck of a drug vial, it can be difficult to obtain a sufficient force in order to obtain a secure locking of the connector around the neck of the vial.




Furthermore, the previously known assemblies for coupling a connector to the neck of a vial or bottle can only accommodate drug vials or bottles of one single predetermined size. In view of the above described deficiencies associated with previously known assemblies and methods for coupling a connector to the neck of a vial or bottle, the present invention has been developed. These enhancements and benefits are described in greater detail hereinbelow with respect to several alternative embodiments of the present invention.




SUMMARY OF THE INVENTION




The present invention in its several disclosed embodiments alleviates the drawbacks described above with respect to conventional assemblies and methods for coupling a connector to the neck of a vial or bottle and incorporates several additionally beneficial features.




Accordingly, a first object of the present invention is to provide a coupling device for coupling a vial connector to a drug vial which eliminates the above-mentioned problems associated with known devices and methods. Furthermore, arrangements configured according to the present invention ensure that vial connectors of different sizes can be coupled to drug vials or bottles of different sizes in a way preventing the cannula of the vial connector from creating a larger hole than necessary in the seal of the drug vial, while ensuring that the vial connector is pressed down over the neck of the vial with a force sufficient for achieving a permanent coupling of the vial connector to the drug vial.




This first object of the present invention is achieved by means of the coupling device comprising first positioning means for holding the drug vial in a first position, and further comprising second positioning means for holding the vial connector in a second position. The coupling device further comprises actuating means for bringing the drug vial and/or the vial connector into a third position in which the cannula penetrates the seal in a direction along an axis substantially perpendicular to a main plane of the seal. According to the invention, the coupling device comprises guiding means controlling the direction, wherein the actuating means are designed for applying a force in the above-mentioned direction on the drug vial and/or the vial connector enabling the locking means to become permanently locked around the neck when reaching the third position. Thereby, the first positioning means are adjustable for holding drug vials of several different dimensions and/or the second positioning means are adjustable for holding vial connectors of several different dimensions. Furthermore, the coupling device is designed for allowing the first and second positioning means to release the vial and the vial connector after having reached the third position.




Further objects of the present invention will become evident from the following description, while the features enabling the further objects to be reached are defined in the dependent claims.




The beneficial effects described above apply generally to each of the exemplary devices and methods disclosed herein as they relate to coupling a connector to the neck of a vial or bottle. The specific structures and steps through which these benefits are delivered will be described in detail hereinbelow.

MODE(S) FOR CARRYING OUT THE INVENTION




As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various and alternative forms. The figures are not necessarily to scale, some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention.




In the following, a preferred embodiment and a number of alternative embodiments of a coupling device according to the invention, intended for coupling a vial connector to a drug vial, will be described with reference to the attached

FIGS. 1-7

.




The coupling device according to the invention is in tended to be used with drug vials


101


(or bottles) of a type comprising a neck


102


havingy an opening I


103


′covered by a seal


104


. Such drug vials are well-known to the skilled person and will not be discussed in greater detail herein.

FIG. 1

shows drug vials


101


and


301


which are of two different sizes, whereas

FIG. 7

shows a drug vial


201


of a third size.




Furthermore, the coupling device according to the invention is intended to be used with vial connectors


105


of a type having locking means


106


,


107


for grasping the neck


102


and at least one cannula


108


for penetrating the seal


104


of the drug vial. In connection with this, it can be mentioned that the drug vials for use with devices constructed according to the invention can have seals


104


;


204


;


304


with different outer diameters, e.g. 14 or 21 mm. Vial connectors of the type in question are well-known to the skilled person and will not be described in greater detail herein. However, vial connectors


105


;


205


;


305


of the type shown in the drawings which include pressure compensating means in the form of an expandable bladder or the like are preferred for use in the coupling device according to the invention.




As illustrated by the vial connector


305


in

FIG. 1

, vial connectors of a type having short locking means


306


alternating with longer locking means


307


are particularly preferred for use with the coupling device according to the invention. Such vial connectors makes the coupling easier, since the longer locking means


307


, after having been brought down around the vial neck


302


, will act as guiding means until also the shorter locking means


306


have been brought down around the vial neck and all the locking means


306


,


307


have “snapped” down around the vial neck


302


into their final positions.




Furthermore, as illustrated by the vial connector


405


in

FIG. 1

, a special adapter with locking means adapted for fitting around the vial neck dimension in question can be pressed down around the cannula


408


, so that the adapter is encircled by the original locking means


406


,


407


of the vial connector


405


. Accordingly, the vial connector


405


can be obtained by means of applying a special adapter onto the vial connector


305


. In this way, by means of providing appropriate adapters, the same vial connector can be utilized for coupling to vial necks of different dimensions. Also, the locking means of the adapter can have short locking means alternating with longer locking means.




According to the invention, the coupling device


109


comprises first positioning means


110


for holding the drug vial


101


in a first position, and second positioning means


111


for holding the vial connector


105


in a second position.




Furthermore, according to the invention, the coupling device comprises actuating means


112


for bringing the drug vial and/or the vial connector


105


′ into a third position in which the cannula


108


′ penetrates the seal


104


′ in a direction along an axis A substantially perpendicular α≈90° to a main plane P of the seal


104


′.




In the preferred embodiment, the first positioning means


110


comprise at least two vial engagement means


114


,


115


(

FIG. 6

) designed for aligning a centerline C of the drug vial with the axis A. As will become evident to the skilled person, many different mechanical designs are conceivable for the first positioning means, e.g. a mechanical design known per se in which the two vial engagement means


114


,


115


are connected by a spring or another elastic member.




In the preferred embodiment, the second positioning means


111


comprise snap-in means


116


designed for aligning the cannula


108


with the axis A. As will become evident to the skilled person, a number of different mechanical designs are conceivable also for the second positioning means, both mechanical designs relying on a spring or an elastic member and/or designs relying on friction between a convenient portion of the vial connector and a portion of the second positioning means.




According to the invention, the coupling device comprises guiding means


113


which control the direction. Of advancement in the preferred embodiment, the guiding means


113


comprise at least one elongate member


119


,


120


which is/are rigidly attached to the support


118


in parallel with the axis A, and which elongate member(s)


119


,


120


is/are designed for sliding contact with the actuating means


112


. However, within the scope of the invention, also other technical designs of the guiding means are conceivable.




According to the invention (FIG.


4


), the actuating means


112


′ are designed for applying a force in the above-mentioned direction on the drug vial and/or the vial connector


105


′ enabling the locking means


106


′,


107


′ (of the vial connector) to become permanently locked around the neck


102


′ (of the drug vial) when reaching the third position. Accordingly, it is conceivable with embodiments of the coupling device which achieve the coupling by means of displacing a vial connector into contact with an immovable drug vial. by means of displacing a drug vial into contact with an immovable vial connector, or by means of displacing both vial connector and drug vial towards each other until they contact each other.




In the preferred embodiment of the invention, the actuating means


112


′ are designed for applying a force in the above-mentioned direction on the drug vial and/or the vial connector


105


′ which is larger than 100 N, and preferably between 147 and 196 N.




By means of using conventional laboratory equipment for force measurements when coupling different vial connectors to different drug vials, the above-mentioned force levels were established as particularly advantageous because they enable coupling of vial connectors and drug vials which are able to provide a very strong permanent coupling, but without requiring an extraordinary physical strength of the person operating the device. However, within the scope of the invention, it is also conceivable with less advantageous embodiments where the actuating means are designed for applying a smaller or larger force than 100 N.




In the preferred embodiment (FIG.


6


), the actuating means


112


comprise a handle


117


which is pivotally attached to a support


118


. However, it is also conceivable with advantageous embodiments of the coupling device according to the invention in which the actuating means


212


comprise a gear wheel


222


and/or a gear rack


223


, as shown in

FIG. 7

, or embodiments in which the actuating means comprise an electric motor, a hydraulic system, or a pneumatic system.




According to the invention, the first positioning means


110


are adjustable for holding drug vials


101


;


201


;


301


of several different dimensions and/or the second positioning means


111


are adjustable for holding vial connectors


105


;


205


;


305


of several different dimensions. This offers great advantages, since one single coupling device according to the invention can fulfil the entire need for a reliable and safe coupling assembly. As will become evident to the skilled person, many different mechanical designs are conceivable for the adjustable first and/or second positioning means.




Furthermore, according to the invention (FIG.


5


), the coupling device


109


″ is designed for allowing the first


110


″ and second


111


″ positioning means to release the vial


101


″ and the vial connector


105


″ after having reached the third position. In the preferred embodiment, the coupling device


109


″ is designed for allowing an operator to release the vial


101


″ and the vial connector


105


′ which is now permanently locked around the neck from the first


110


″ and second


111


″ positioning means by means of hand power, after having reached the third position. As has become evident from the foregoing, this can be accomplished e.g. in the way shown in

FIGS. 6 and 7

, in which the first positioning means


110


comprise recessed vial engagement means


114


,


115


, which preferably are spring-loaded, and the second positioning means


111


comprise flexible snap-in means


116


.




In an alternative embodiment, illustrated in

FIG. 7

, the coupling device


209


comprises a lever


221


for inducing engagement or release of the vial


201


and/or the vial connector


205


to/from the first


210


and/or the second positioning means.
