Exemplary embodiments of the present invention relate generally to mechanical devices, and more particularly to assemblies and elements thereof for holding, securing, protecting and transporting vials and other such vessels.
Vessels of various types are known in the art for holding liquids, solutions, powders and numerous other materials. In the medical field, liquid, powder, capsule, and other forms of medication are often stored in vessels typically referred to as vials, which commonly take the form of a small, closed glass or plastic vessel. Vials may also be used in the field for storing biological materials such as blood samples and other bodily fluids and the like. Vials may be configured with screw-on caps, press-on caps, caps penetrable to pipette tips or needles, and other such varieties of lids generally depending upon intended use.
Vials must often be stored or transported during use. Many medications and biological materials must be stored in temperature controlled environments to avoid negative effects on efficacy or the general integrity of the materials. Similarly, vials are often transported from storage to the location at which the medication is to be administered, for example, or from the procurement site of the materials (e.g., blood) to storage or a testing laboratory. In medical settings, such as at a hospital, several vials may be needed for administration to a patient or several patients. Several kinds of medication may be required, or several vials each containing one dose of medication may be necessary during medical treatment.
It is known to utilize vial trays, boxes and other similar structures, sometimes contained within a carrying case, to transport multiple vials. Known structures typically include at least one surface with apertures sized to receive vials therein, and to maintain them in a substantially lid-up vertical position. These devices can be carried on a shoulder strap, placed on a wheeled cart, or carried by simple hand grips. Some carriers include additional vial retention means for retaining the vials within the apertures, or alignment features for use with common laboratory testing equipment, as disclosed in U.S. Pat. No. 7,132,082 to Aviles et al.
While known vial carrier configurations advantageously allow for the transport or storage of multiple vials simultaneously, they are not helpful in intra-facility transport by way of pneumatic tube systems. Many medical facilities use pneumatic tube systems, typically with cylindrical containers, in order to quickly transport materials between locations in a medical facility, including pharmaceuticals and biological materials. Traditional vial carriers are often much larger than and are incompatible with pneumatic tube sizes. In order to transport vials utilizing such systems, therefore, vials are typically placed directly into pneumatic tube containers, or into protective sleeves designed to fit securely within such containers.
In the former case in which the vials are placed directly into a pneumatic container, damage can occur to the vials as a result of the forces exerted on them as the pneumatic container traverses the tube systems. Manufacturers of vials have designed more robust vials in response, resulting in a significant expense to the users, who alternatively must deal with the increased risk and incidence of vial breakage during transport.
In the latter case, protective sleeves are used during pneumatic transport of vials to protect the vials from damage. An exemplary vial sleeve is disclosed in U.S. Pat. No. 3,072,362 to Allen, for example. While this development provided advantageous protection to vials in transport without the need for more robust vials, the sleeves have a disadvantage in that each embodiment must be manufactured to fit a particular vial shape and size configuration. Furthermore, the insertion and removal of the vials from the sleeve encourages contact with the lid portion of the vials, thereby introducing an increased risk of contamination due to unnecessary handling.
It is also known to provide elastic holding films within pneumatic containers for the purposes of suspending articles therein to avoid contact with the interior container surfaces during pneumatic transport. U.S. Pat. No. 6,015,246 to Yamane et al. discloses one such system in an effort to protect articles being transported within pneumatic systems. Such systems have advantages similar to protective sleeves, and potentially may be used with a wider variety of vial sizes. However, the elastic holding films do not make suitable storage or transport systems outside of the context of pneumatic tube transport. For example, the complexities of manufacturing such devices increases as multiple sub-compartments (and multiple elastic films) are required for transporting multiple vials. Furthermore, such devices do not provide for uniform orientation of vials—a disadvantage borne by the goal of such systems to be compatible with multiple types and sizes of articles.
It is therefore an unmet need in the prior art for a vial transport assembly that provides for the protection of a plurality of vials during both storage and transport, and that is useful both within existing pneumatic transport systems and outside of said systems. Further, it is needed for such a system to also be readily able to secure vials of varying types and sizes and to provide access to the vials by users in a manner that does not require excessive contact with vial lids.
Exemplary embodiments of the present disclosure pertain to an element of a vial transport assembly, the assembly comprising a plurality of the elements joined together to form a unitary row of elements. An object of the invention is to provide each element with an elongate member having inner and outer faces with a pair of side edges and a pair of end edges, the end edges shorter than the side edges, and the inner and outer faces spaced apart to define a thickness. The elements have a means for receiving and retaining a vial, removably seated on the inner face to align an elongate axis of the vial received there in parallel to the side edges, and further a pair of end members, each end member arranged at one of the end edges extending normal to the inner face and having lateral edges.
Another object is to provide elements with complementary means, arranged along the side edges, for pivotally joining the element to another of the plurality of elements with the lateral edges of the end members of adjacent elements in registration.
An additional object of the present invention is to provide a gripper as the means for receiving and retaining the vial, the gripper having a portion having a bottom face in registration with the inner face when seated thereon. The gripper is provided with a pair of angled sides, each angled side extending away from the bottom face and toward one another thereby forming a pair of congruent, interior, acute angles with respect to the bottom face. A channel is further provided having a cross section adapted to receive and retain the vial extending between the pair of angled sides in parallel to the pair of side edges of the elongate member.
A further object of the invention is to provide the gripper wherein the cross section of the channel comprises a circular arc subtending an angle greater than π radians.
Another object of the invention is provided wherein the elongate member includes one or more apertures extending through and normal to the inner and outer faces. For each aperture, the gripper is further provided with a base extending normal to the bottom face and having a width smaller than the aperture and a length equal to or greater than the thickness of the elongate member, and a retention tab extending from a distal end of the base and having a width greater than the aperture.
Another object of the invention is to provide each attachment leg of the gripper with a tang extending from the retention tab for use in attaching the gripper to the element. In some embodiments, the gripper is formed of a unitary cast of silicone material. In others, the gripper is formed of a unitary injection molded thermoplastic elastomer.
An object of the invention is to provide a means to close a vial transport assembly composed of the elements during transportation. Two or more elements may be provided with complementary means, arranged along the lateral edges of each of the end members, for reversibly maintaining the lateral edges of the end members of adjacent elements in registration. In some embodiments, each end member is further provided with a pair of complementary magnets arranged for reversibly maintaining the lateral edges of the end members of adjacent elements in registration, each complementary magnet being inset within one of the lateral edges of the end members. In some embodiments, each end member is further provided with a pair of complementary magnets arranged for reversibly maintaining the lateral edges of the end members of adjacent elements in registration, each complementary magnet being secured to one of the lateral edges of the end members.
A further object of the invention is to provide a vial transport assembly from the vial transport elements. In some embodiments, a vial transport assembly is made of a first end element, a plurality of interior elements, and a second end element. Each of the end elements has an elongate member having inner and outer faces with a pair of side edges made of a free edge and a pivot edge, and a pair of end edges, the end edges shorter than the side edges and the inner and outer faces spaced apart to define a thickness. The end elements further have a pair of end members, each end member arranged at one of the end edges extending normal to the inner face and having an outer lateral edge and an interior lateral edge. The interior elements are each provided with an elongate member having inner and outer faces with a pair of pivot edges and a pair of end edges, the end edges shorter than the pivot edges and the inner and outer faces spaced apart to define a thickness, and a pair of end members, each end member arranged at one of the end edges extending normal to the inner face and having a pair of interior lateral edges.
Another object of the invention is to form the vial transport assembly of a unitary row of adjacent elements formed by joining together the pivot edges of the first end elements, the plurality of interior elements and the second end element in succession, wherein the free edge of the first end element forms a first end of the unitary row and the free edge of the second end element forms a second end of the unitary row.
Another object is to provide the assembly with complementary means, arranged along the pivot edges, for pivotally coupling adjacent elements in the unitary row together, complementary means for reversibly maintaining the outer lateral edges of the first end element in registration with the outer lateral edges of the second end element, and means for receiving and retaining a vial, removably seated on the inner face of one or more elements in the assembly. In some embodiments, said means for receiving and retaining a vial is removably seated on the inner face of each of the elements in the assembly.
In some embodiments of the assembly, the complementary means for reversibly maintaining the outer lateral edges of the first and second end elements in registration is provided as a plurality of complementary magnets arranged for reversibly maintaining the outer lateral edges of the first and second end elements in registration, each complementary magnet being inset within one of the outer lateral edges therein.

A gripper is provided for each element having a bottom face in registration with the inner face when seated thereon, a pair of angled sides each extending away from the bottom face and toward one another thereby forming a pair of angles congruent, interior, and acute with respect to the bottom face, a channel having a cross section adapted to receive and retain the vial extending between the pair of angled sides in parallel to the pair of side edges of the elongate member, and an attachment leg for each aperture in the corresponding element. In some embodiments, each attachment leg is provided with a base depending normally from the bottom face and having a width smaller than the aperture and a length equal to or greater than the thickness of the elongate member, a retention tab extending from a distal end of the base and having a width greater than the aperture, and a tang extending from the retention tab.
Each gripper is removably seated on the inner face of each element in the unitary row of elements by inserting each tang and retention tab through a corresponding aperture in the elongate member wherein the retention tab is seated upon the outer face thereof. Each tang is trimmed wherein it is separated from the gripper, and a plurality of complementary magnets are arranged on the outer lateral edges of the first and second end elements thereby reversibly maintaining the outer lateral edges in registration.
It is an object of this invention to provide a vial transport assembly and elements thereof of the type generally described herein, being adapted for the purposes set forth herein, and overcoming disadvantages found in the prior art. These and other advantages are provided by the invention described and shown in more detail below.
Novel features and advantages of the present invention, in addition to those mentioned above, will become apparent to those skilled in the art from a reading of the following detailed description in conjunction with the accompanying drawings wherein identical reference characters refer to identical parts and in which:
Exemplary embodiments of the present invention are directed to vial transport assemblies and elements thereof. While it has been discovered that the invention disclosed herein is of particular usefulness in the field of healthcare, it should be noted that use of the assembly is not considered limited thereto. To that end, references made throughout this disclosure to “vials” are to be interpreted to encompass containers, bottles and other such vessels for holding substances of generally any form, and not as limiting. The reference and depiction of medical vials generally is considered exemplary and for purposes of brevity and clarity no attempt has been made to describe numerous equivalents thereof.
A perspective view of an exemplary embodiment of a vial transport assembly 2 is depicted in
Embodiments of the invention include a means for receiving and retaining a vial 8 seated thereon, for example one or more grippers 6 as shown in
The exemplary element 4 includes an elongate member that serves as one of a plurality of sides of the vial transport assembly when assembled. The elongate member includes inner 12 and outer 14 faces spaced apart in parallel such that a thickness is defined. In preferred embodiments, the inner and outer faces are rectangular in shape. When the vial transport assembly is closed, the inner faces 12 will face toward the center of the assembly generally, and the outer faces 14 will serve as an exterior surface of the assembly. The elongate member has generally a pair of parallel side edges 16 and 18, a pair of parallel end edges 20 and 22, and it is preferred that the side edges be substantially longer than the end edges.
At each end edge 20 and 22 is arranged an end member 24 and 26, respectively. The end members 24 and 26 each extend normal to the inner face 12 of the elongate member, and when the vial transport assembly is closed, form a portion of the ends of the vial transport assembly, together with the end members of other elements forming a unitary row. The shape of the end members in any particular embodiment may be selected to suit the requirements of a particular application, but they should generally at least be configured with a pair of lateral edges. For the exemplary embodiment of the element depicted in
Each element 4 is further provided with complementary means for pivotally joining the side edge of one element to the side edge of another adjacent element in such a manner that a unitary row is formed (e.g., the unitary row of elements 4 of the vial transport assembly 2 depicted in
In some embodiments, the element is provided with complementary means, arranged along the lateral edges of each of the end members, for reversibly maintaining the lateral edges of the end members of adjacent elements in registration. This complementary means is employed to maintain the assembly of elements in a closed position. Some embodiments instead may include complementary mechanical latching means on the arranged on the end elements of a unitary row, but for pneumatic tube transport it is preferred that the means for reversibly maintaining the lateral edges of the end members of adjacent elements in registration does not protrude from the exterior surfaces of the assembly. An exemplary element 4 is further depicted with a pair of complementary magnets 40 and 42 secured at the lateral edges of each of the end members 24 and 26, respectively. A first pair of complementary magnets 40 is arranged on the lateral edges 28 and 30 of one end member 24, and a second pair of complementary magnets 42 is arranged on the lateral edges 32 and 34 of the other end member 26. The magnets are complementary in that one magnet in each pair 40 and 42 is attracted to the opposing magnet arranged on a lateral face of an adjacent element of a unitary row in registration. The magnets reversibly secure the edges of adjacent elements in order to maintain the assembly in a folded or closed position. In one embodiment, the magnets are inset within the lateral edges of the end members. Alternatively, the magnets can be attached to the surface of the lateral edges, for example with an appropriate adhesive. The complementary magnets 40 and 42 are shown with a rectangular shape, but any desired shape of magnet may be used without departing from the scope of the invention. For example, a circular inset is preferable, and thus in some embodiments circular magnets are used.
