8475404
This disclosure relates to a mixing and transfer device for injectable medication.
Lypholized and similar liquid drugs are typically provided in medicament vials with standard elastomeric closure sizes, such as 20 mm and 13 mm diameter closures. Administration of these drugs, if administered to patients via routes such as intramuscular, intravenous, intracutaneous, and the like, require that delivery devices be attached to a syringe, and then administered to the patient, for example using needles. The needles used to administer the drug to the patient are often different from the needle or access device used to access the medicament vial(s). Certain needle types are special for drug vials—such as anti-coring needles—and would be inappropriate for use when injecting a patient. For instance, a pharmacy technician may use a high flow rate needle to withdraw diluent from one source, and inject it into a lyophilized drug vial. The vial would be mixed up, and drawn back into the syringe—or perhaps a new clean syringe. Then often times the drug preparation needle is removed and disposed of and an alternate sterile needle, appropriate for the specific type of patient injection (e.g. deltoid intramuscular), would be placed on to take the prepared drug-filled syringe with new capped needle to the patient. The prescribed mixing and preparation of drugs vary, which may require certain drugs to be mixed carefully, or flow through specific sized needles. The lyophilized drug may be expensive, requiring that a little as possible or substantially nothing is left in the drug vial.
Vial elastomeric closure design and materials vary and may require the user to match up the appropriate needle or access device with the medicament vial. The medicament injection process varies by both the location and type of injection. Since the drug preparation is often completed by a technician or nurse, not the prescriber, and/or different from the administrator of the medication, there may be multiple steps in the process that may result in error. Additionally, due to the number of steps, the time of preparation can be significant, adding cost and complexity to the process. Finally, switching needles often for drug preparation and administration may lead to an increased likelihood of needle-stick injuries.
Described herein is a vial access device that addresses several of the issues described above. The vial access device described herein reduces the number of steps and potential errors for the preparation and the administration of drugs that are delivered to patients via needles, spray nozzles, or luer connectors. The vial access device described herein provides larger flow paths to ease and speed up drug preparation, and may protect the drug and/or blood products from mechanical breakdown or hemolysis. The vial access device described herein protects the needle or component for injection during preparation, maintaining its cleanliness, sharpness, and assures its readiness for patient administration. The vial access device described herein may prevent or substantially eliminate unintentional and/or accidental needle-sticks of users and healthcare personnel by accommodating needle safety mechanisms.
In one aspect, a device for mixing and transferring is described. The device comprises a housing having first and second open ends, a vial accessing member having at least one fluid conduit therethrough, the vial accessing member extending generally outwardly from one end of the housing. The device comprises a syringe accessing member having at least one fluid conduit therethrough, the syringe accessing member extending generally outwardly from the other end of the housing having the vial accessing member, the syringe accessing member and the vial accessing member in fluid communication therewith. In one aspect, the device further comprises receiving means within the housing, the receiving means configured to receive a dispensing member of the syringe.
In another aspect a combination is described. The combination comprising a device for mixing and transferring, a fluid delivery device, and optionally a container having a transferable substance. The device comprises a housing having first and second open ends, a container accessing member having at least one fluid conduit therethrough, the container accessing member extending generally outwardly from one end of the housing. The device comprises a fluid delivery device accessing member having at least one fluid conduit therethrough, the fluid delivery device accessing member extending generally outwardly from the other end of the housing having the container accessing member, the fluid delivery device accessing member and the container accessing member in fluid communication therewith. The fluid delivery device is reversibly securable to the fluid delivery device attaching means. The fluid delivery device comprises a dispensing member at a proximal end, an access port at the proximal end configured to receive the fluid delivery device accessing member, and a plunger at a distal end, the plunger having a distal end slidably received towards the dispensing member of the syringe. The combination optionally comprises at least one container reversibly securable to the container attaching means, the container optionally comprising a transferable substance.
Disclosed herein is a device for mixing and transferring. The device comprises a housing having open ends, a container accessing member having at least one fluid conduit therethrough, the container accessing member extending generally outwardly from one open end of the housing. The housing also comprises a fluid delivery device accessing member having at least one fluid conduit therethrough, the fluid delivery device accessing member extending generally towards the other open end of the housing, the fluid delivery device accessing member and the container accessing member in fluid communication therewith. The device further comprises receiving means within the housing, the receiving means configured to receive a dispensing member of the fluid delivery device. The access device is configured to provide an interface between the contents of a container and a fluid delivery device. The access device is configured such that the fluid delivery device and the container may reversibly and sealably mate to the access device and be in fluid communication therewith.
Access Housing
The access device comprises a housing having open ends, a container accessing member having at least one fluid conduit. The container accessing member extends generally outwardly from one end of the housing. The device also comprises a fluid delivery device accessing member having at least one fluid conduit therethrough, the fluid delivery device accessing member extending generally outwardly from the opposite end of the housing having the container accessing member, the fluid delivery device accessing member and the piercing accessing member in fluid communication with each other.
The fluid delivery device accessing member is configured to bypass the dispensing member of the fluid delivery device to allow a higher flow rate during aspiration and to maintain the integrity of the dispensing member during preparation of the fluid. The fluid delivery device accessing member and the access housing may comprise any number of parts, which may be joined together in a sealable relationship. In one aspect, the access device is a vial access device configured for accepting a drug vial. The drug vial contains a pierceable septum or the like. The vial access device comprises a piercing member extending from the end of the vial access device housing. The vial access device is configured such that the vial accessing member pierces the septum of the vial to access the vial.
The vial access device preferably has one or more piercing members, at least one of the piercing members having a lumen open at its distal end. The proximal end of the piercing members are advantageously attached via the interconnecting conduits within the access housing to provide fluid communication between the container, such as a drug vial, and a fluid delivery device, such as a syringe. The piercing member is adapted to support and penetrate standard drug vials filled with powdered or lyophilized drugs or liquid diluent, while the syringe is adapted to transfer liquid diluent and drug solutions between the vials and the syringe. At least one lumen is open at the vial accessing member and provides a fluid communication with the interconnecting conduit. Venting of a piercing member to the ambient may be provided.
The vial access device may further comprise attachment means to reversibly secure the vial access device to the vial. The vial access device may also comprise a plurality of flexible primary tabs extending toward the second end of the device where they form a vial attachment latch at its distal end for use in reversibly securing the component to a vial. Each tab having the vial attachment latch may also have a secondary tab extending from the primary tab toward the first end; a secondary tab also having an end that may have a gripping means integrated therewith. The component may also include tabs used for guiding the vial access adapter onto drug vial without attachment latches. The vial access adapter may be removed from drug vial and remain attached to the fluid delivery device.
In one aspect, the sealable interface of the other open end of the vial access device is configured for a standard syringe interface. Thus, the sealable interface may be designed to sealably mate with standard or custom syringes. The sealable interface may be permanently affixed to the syringe or may be configured to be non-releasable upon engagement with the syringe. The sealable interface permanently affixed to the syringe may reduce tooling requirements and/or costs. The housing and any of its integrated or attached components may be constructed of any of a variety of materials. Preferably, the housing is constructed of a material that is biocompatible and able to withstand exposure to various sterilization methods and the intended fluid media. Materials that may be used for the housing include, but are not limited to, polycarbonate, polyethylene, polypropylene, PBT and the like. Glass or carbon fibers, fillers or other strengthening media may be added to these plastics for rigidity as required.
Fluid Delivery Device Accessing Member
The access housing comprises a fluid device accessing member configured to access a fluid delivery device via an accessing member. The accessing member has at least one fluid conduit. The accessing member extends generally toward the other open end of the access housing, the fluid delivery device accessing member and the container accessing member being in fluid communication with each other.
In one aspect, the fluid delivery device is a syringe having a dispensing member and the fluid delivery device accessing member is a syringe accessing member. The syringe accessing member has at least one fluid conduit. The syringe accessing member extends generally toward the other open end of the access housing, the syringe accessing member and the container accessing member being in fluid communication with each other.
The syringe accessing member comprises a fluid path to bypass the dispensing member of the syringe. For example, the vial access device provides for fluid bypass of the needle of a syringe. The vial access device may be configured such that a higher flow rate when drawing fluid into the fluid delivery device is possible than would be by using the dispensing member of the fluid dispensing device. The fluid bypass also maintains the integrity of the dispensing member (e.g. sharpness of a needle) until it is needed for final dispensing. The fluid bypass may comprise a fluid passage in the vial access device in fluid communication with a sealable access port (described herein) into the distal end of the syringe barrel adjacent the dispensing member such that during transfer and/or mixing, fluid is substantially diverted from traversing the dispensing member. The access port may be a self-closing, sealable passage into the syringe barrel such that during an injection stroke, fluid is delivered only through the needle. This may allow, for example, a smaller needle size on the fluid delivery device thereby reducing discomfort to the patient during injections.
Receiving Means
The access housing may define receiving means within the housing. The receiving means are configured to receive a dispensing member of the fluid delivery device within the access housing. In one aspect, the receiving means comprises an inner portion within the housing providing a sheath-like area for accommodating a dispensing member, for example a needle, including a needle cover. The receiving means may include the external surrounding areas of the fluid delivery device accessing member. In one aspect the receiving means cooperates with the fluid delivery device accessing member to provide an isolated flow path so that fluid media does not come into direct contact with external surfaces of the dispensing member or its cover. Thus, the receiving means isolates the dispensing means such that its external surfaces remain free and clean from drug product during the preparation of the drug, prior to injection into a patient.
Fluid Delivery Device
The fluid delivery device provides containment of fluid withdrawn from or introduced to the container and/or administrated to a subject. The fluid delivery device component comprises an open first end that may incorporate flange for ergonomic control; a second end with any number of openings for fluid communication, an inner portion providing a sealable, sliding interface and a distal lower housing having an outer portion, which may be adapted to latching/alignment elements for secure attachment and/or positional (configuration) control when mated with the access device housing.
In one aspect the fluid delivery device is a syringe. The syringe comprises at least one access port capable of receiving the fluid delivery device accessing member of the access housing. The access port facilitates drawing fluid in through the bypass fluid channel of the syringe accessing member and delivery of the fluid to the syringe, bypassing the dispensing member. The access port may be a 2-way port, allowing fluid to be transferred from the fluid delivery device to the container. The syringe comprises a plunger having a first end and a second end; a first end which may have gripping means for ergonomic control and a second end that may have any number of extensions. An attachment means is provided proximal to or integrated with the second end for attaching a syringe stopper. The syringe stopper may have any number of contiguous sealing elements about its outer portion perimeter for creating a slidable seal within the syringe barrel. The syringe stopper may be constructed of any of a variety of materials which are biocompatible, sterilizable, and able to withstand exposure to the intended fluid media for the system. These materials preferrably are resilient or reasonably deformable and may include, but are not limited to, elastomers such as rubber, silicone and thermoplastic or thermoset elastomers.
Access Port
The access port provides fluid communication between the fluid delivery device accessing member and the fluid delivery device. The access port is preferably re-sealable. In one aspect, the access port is a self-closing, sealable access port positioned at the distal end of the fluid delivery device adjacent the dispensing member such that during transfer and/or mixing, fluid is substantially diverted from traversing the dispensing member. The sealable access port may be comprised of sealing means, a pre-slit septum portion and a thin membrane section, or combinations thereof. In one aspect, the sealable access port is a pre-slit septum extruded with a general parabola shape, a duck-bill shape, or combination of similar geometries, which may be pre-slitted for re-sealable and re-useable access. In one aspect, the access port is a “duckbill” check valve. In another aspect, the access port is a pre-slit septum with a parabola-like extrusion that may further function as a check valve.
In one aspect, the sealable access port comprises or is integral with a deformable membrane. The deformable membrane, as further described herein, provides for substantially fluid-sealed operation and may provide activation of a needle-stick safety mechanism. The access port may be any of a variety of materials which are biocompatible, sterilizable, and able to withstand exposure to the intended fluid media for the system. These materials preferably are resilient or reversibly deformable and may include but are not limited to elastomers such as rubber, silicone and thermoplastic or thermoset elastomers.
Fluid Delivery Device Lower Housing
The lower housing comprises a suspended portion across the inner diameter thereof. The suspended portion comprises a deformable section that provides communication between the fluid delivery device and the needle stick safety mechanism for activation. The suspended portion may be an elastomeric membrane, which may function to maintain a clean, leak-free syringe. The lower housing also may provide for attachment of the fluid delivery device with the access device. In the case of a spring-loaded needle-stick safety protection mechanism, the lower housing may provide a fastening means for a spring and/or catch mechanism. The lower housing preferably does not hinder the fluid path into the fluid delivery device.
The lower housing comprises attachment means allowing for sealable joining to a fluid delivery device, an elastomeric portion to create a hermetic seal upon joining; attachment members for substantial joining of a dispensing member and an opening or set of openings for allowing fluid to pass through the dispensing member and access to the access port of the fluid delivery device.
Fluid Dispensing Member
The fluid dispensing member provides fluid communication between the fluid delivery device and a patient or may be used to access a vial. In one aspect, the fluid dispensing member is a hollow piercing member. The fluid dispensing member is preferably a needle, a blunt cannula, a spray nozzle, a male valved adapter, female valved adapter, a luer connector, or a combination of a luer connector with any of the above fluid dispensing options. In one aspect, the fluid dispensing member is a needle of any size or gauge conventionally used for drug administration. The fluid dispensing member is generally comprised of an open first end and an open second end. In one aspect, the second end is configured such that a sharp, or piercing end is provided. The fluid dispensing member may be constructed of metal or plastic. In one aspect, the fluid dispensing member is of stainless steel.
In one aspect, the dispensing member further consists of a dispensing member cover. The dispensing member cover is constructed to provide needle-stick protection and/or to maintain sterility of the dispensing member prior to use. In one aspect, the dispensing member cover is mechanically sealed with the dispensing member and/or the attachment member(s) of the dispensing member. This sealing relationship prevents air from being aspirated or expelled during fluid preparation. In one aspect, the needle cover is sheathed within the receiving means of the access housing. The needle cover may be constructed from any of a variety of materials which are biocompatible and/or sterilizable.
Needle-Stick Safety Mechanisms
The aforementioned needle cover may provide some level of protection for the user from needle-stick prior to injection into a patient. Another level of needle-stick safety may be implemented to the fluid delivery device. For example, once the device has been used, a needle-stick safety mechanism may passively deploy a covering device or mechanism that covers at least the needle-tip. In another aspect, the needle-stick safety mechanism may be activated by the user to deploy a covering device or mechanism that covers at least the needle-tip and protects the user and others from accidental needle sticks. Additionally, by housing the needle assembly within the vial access device and assembling the device with this needle-stick safety mechanism during manufacturing provides greater safeguards during assembly. Passive needle-stick safety mechanisms may include, but are not limited to, an internal end-of-stroke needle-stick protection release mechanism, defined herein, as well as known needle protection devices, both passive and active (e.g., button, slides, door, etc.).
In one aspect, the needle stick safety mechanism comprises means for the passive deployment of the mechanism at or near the end of the drug delivery stroke of the plunger. In one aspect, the needle stick safety mechanism comprises, at least one protrusion; the at least one protrusion cooperatively coupled to the deformable section of the lower housing to displace a releasable latch in proximity to the distal end of the syringe, releasing the stored energy means. The protrusion may be at the end of a syringe plunger and interact with the corresponding latch means by contacting the deformable section of the lower housing at the end of stroke or when bottomed out in the syringe barrel. Upon full injection of the fluid from within the syringe, and at substantially the end of stroke or when substantially bottomed out in the syringe barrel, the at least one protrusion causes the release of the latch means and deploys the components of the needle stick safety mechanism, sending the needle-tip cover toward the needle tip.
In one aspect, the needle-tip cover comprises latches, in part, that mate with mating latch means (or shelving) within the syringe lower housing or in proximity to the syringe distal end. When a releasing force is applied, the latch arms release stored energy and traverse the needle-tip cover. External force applied directly or indirectly to the latches releases the needle-tip cover of the safety mechanism, which is acted on by stored energy means, sending the needle-tip cover toward the needle tip.
In one aspect, the needle-tip cover component comprises an open inner portion, an outer portion, a first end and a second end; the outer portion having an attachment means for a spring; the first end having one or more latching means. The needle tip cover preferably includes a guide hole for sliding along a needle. When the needle-tip cover guide hole passes the needle-tip, the spring, having been assembled off-center with the needle centerline, moves the needle-tip cover off-center and onto the needle tip. The spring may be of a traditional metal wire form, or be made of any material including, but not limited to an elastomer or plastic, a bellows type, a helical coil with flat ends for mounting, a double helix type, and the like, or may comprise one or more materials.
In one aspect, the needle stick safety mechanism may comprise a torsional member loaded to provide stored energy that is released at the end of the plunger stroke. Torsional members may be, but are not limited to, torsion springs, leaf springs or tension springs coupled such that when the needle-stick safety mechanism is released, the torsional spring or springs will force its coupled members from a collapsed configuration to an extended configuration. Torsional members may be steel forms, plastic forms or elastomeric forms.
Alignment Means
The access device disclosed herein may include positional control and/or alignment control for the fluid delivery device accessing member of the access device to properly mate with the fluid delivery device. For example, rotational camming control may be used, requiring the user to twist the access device to fully seat the fluid delivery device into the activated configuration defined by being able to bypass the needle for aspiration via the fluid accessing member penetrating the access port. In another aspect, locking latches on the syringe barrel and mating latch ledge geometry on the vial access adapter to define the activated and un-activated configurations, requiring the user to actuate the latches in order to move between configurations. In this way, the access port would not be accessed until use. Thus, just prior to use, the user moves the fluid delivery device from an assembled position (pre-accessed position) to the “use” position (access position). The alignment features further may provide for proper alignment of the fluid delivery device accessing member with the access port.
Manufacturing
All of the proposed embodiments can be injection molded with the exception of the needle. Design intent may be such that designs are molded with simple open/close tooling to reduce tool cost and cycle times. The helical, metal spring would not be injection molded, however an elastomeric bellows-type spring may be. Many of the clip designs are molded with simple open/close tooling in mind to reduce tool cost and cycle times. Where feature definition may not be able to be achieved by single tool molding; ultrasonic welding, adhesives or mechanical retention may be employed to join components. Furthermore, where dissimilar materials may be advantageous (i.e. the syringe septum portion), a 2-shot molding technique may be utilized. For embodiments that may use a capping means as described herein, it may be coupled such that it seals accordingly, but may also be removed without significant force. Adhesives may be required to substantially join components, particularly in the case of designing for interface with an off-the-shelf syringe. Adhesives may be employed to substantially join components, particularly attachments that may be coupled with luer connections, where applicable. Adhesives may be but are not limited to: cyanoacrylate, 2-part epoxy, heat-activated resin, UV cured adhesive and hot melt. Joining may also be achieved through, but not limited to, the use of a solvent bonding, ultrasonic welding, and/or heat-staking means.
Use of the Vial Access Device
In the foregoing, the fluid delivery device is represented by a syringe, however, any fluid delivery device may be used. The exemplary combination consists of a needled syringe assembly and a vial access device that reversibly receives and seals to the syringe at one end. The vial access device reversibly receives a drug vial at another end. Optionally, retention means for securely attaching the vial and/or the syringe to the vial access device are used. Such means may provide audio, visual, or tactile indications upon correct assembly. Optionally, one or more removal tabs, as defined herein, may be included on the vial access device to facilitate removal and/or attachment of vials in sequence. Upon assembly, the combination establishes a fluid flow path that provides fluid communication between the syringe and the vial. Fluid communication between the syringe and the vial bypasses the needle or dispensing means of the syringe. For example, the vial access device accommodates needle or other dispensing means of the syringe such that, within the adapter, it is sheathed and/or isolated from fluid communication between the syringe and the vial. In one aspect, fluid communication between the syringe and the vial comprises a fluid path bypass.
In one aspect, the combination, with the syringe and vial sealably connected to the vial access device, allow for two configurations of activation: an un-activated configuration in which fluid transfer from the vial is prevented or substantially eliminated and/or an activated configuration where the needle of the syringe is bypassed. Bypass of the needle is via a secondary fluid passageway, allowing higher flow by virtue of a larger diameter conduit than that of the syringe needle. Bypass is achieved by an accessing member with an isolated flowpath internal to the vial access device. Upon activating the system, the accessing member pierces a pre-slit septum positioned in proximity to the needle of the syringe that leads directly to the interior of the syringe barrel.
After the syringe assembly is filled, it may be removed from the vial access device. The pre-slit septum of the syringe self-closes upon detachment. A needle cover may also be housed within the vial access adapter and assembled about the needle to prevents air from being aspirated or expelled during fluid preparation, as well as for safe and clean transport. Once the needle cover is removed it may then be used for injectable drug delivery via the needle.
In another aspect, the combination comprising a syringe, needle cover, vial and vial access device may allow for three positional configurations:
After the vial access device is employed and the syringe contains the liquid or reconstituted material of the vial, the combination comprising a syringe, needle cover, and needle stick safety mechanism may allow for two operational configurations:
The method of using the vial access device as described greatly reduces the number of steps typically associated with access, preparation, and administration of drugs. Additionally, the prescribed configurations as detailed here, assure optimal preparation and delivery of a drug as waste can be reduced by the design of the vial access spike; mechanical breakdown of the drug products can be avoided by high flow fluid paths; time and complexity is reduced by elimination of steps to the user and by housing a needle or other dispensing means within the assembly.
Referring now to the drawings, various illustrative embodiments will be described.
While the invention has been described in detail and with reference to specific embodiments thereof, it will be apparent to one skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention. As used herein, “comprising,” “including,” “containing,” “characterized by,” and grammatical equivalents thereof are inclusive or open-ended terms that do not exclude additional, unrecited elements or method steps. “Comprising” is to be interpreted as including the more restrictive terms “consisting of” and “consisting essentially of” As used herein, “consisting of” and grammatical equivalents thereof exclude any element, step, or ingredient not specified in the claim. As used herein, “consisting essentially of” and grammatical equivalents thereof limit the scope of a claim to the specified materials or steps and those that do not materially affect the basic and novel characteristic or characteristics of the claimed invention.
This application claims the benefit of U.S. Provisional Application No. 60/965,555, filed Aug. 21, 2007; 61/003,676, filed Nov. 19, 2007; and 61/066,974, filed Feb. 25, 2008, all of which are incorporated herein by reference in their entirety.
