Description

Technical Field

[0001] The present invention relates to a cover for a medical infusion device, a medical infusion device, and a method for manufacturing the cover. The present invention is particularly suitable for the medical industry.

Background Art

[0002] In the present application, it is understood that the distal end portion of a component or device means the end portion farthest from the user's hand, and the proximal end portion means the end portion closest to the user's hand. Similarly, in the present application, "distal direction" is understood to mean the direction of injection with respect to the medical container of the present invention, and "proximal direction" means the direction opposite to the direction of injection, that is, the direction toward the user's hand holding the container for the injection operation.

[0003] Medical infusion devices, such as prefillable or prefilled syringes, typically comprise a hollow body or barrel that forms a container for a medical product. This body comprises a distal end portion, optionally provided with a needle, and a proximal end portion, typically provided with a flange.

[0004] There is an increasing need to ensure individual traceability from the manufacturing process of medical containers such as medical infusion devices through to final labelling, final use, and disposal.

Summary of the Invention

Problems to be Solved by the Invention

[0005] For example, from International Publication No. WO 2017 / 157784, receptacles are known that have a cylindrical lateral surface surrounded by a series of printed machine-readable unique identifier codes. These printed unique identifier codes enable the tracking and tracing of each receptacle along the supply chain. However, since these identifier codes are printed on the outside of the receptacle, they can be removed or damaged, for example, during the handling or use of the receptacle. Also, since the unique identifier codes cover part of the receptacle, they can potentially affect the visual inspection process by the user. Finally, an inkjet printer is used to print the identifier codes on the outside of the receptacle. However, this printing method uses ink and can lead to a risk of contamination of the receptacle. Furthermore, if the receptacle is packaged, for example, in a sealed state, there may be no access to these printed identifier codes.

[0006] Furthermore, from European Patent Application Publication No. EP 2019 / 305879, a plastic flange for a medical container is known, said flange comprising a remotely readable electronic component such as an RFID tag including an RFID chip and an RFID antenna for remote identification of the medical container. However, said medical container requires a complex manufacturing process, especially including the assembly of the plastic flange onto a glass barrel.

[0007] U.S. Patent Application Publication No. 2019 / 0217018 discloses an RFID-tag-compatible shield assembly that provides a sterile enclosure for a drug delivery port of a drug container. The container can be a needleless prefilled syringe, a vial, a cartridge, or a foldable bag or pouch. The RFID tag is fixedly attached to one or more components of the shield assembly by co-molding or another form of permanent or removable attachment. The RFID tag is actually an RFID chip that can optionally communicate electrically with an antenna. In one embodiment, the shield assembly comprises two relatively inflexible components such as a hub and a removable top. The removable top can accommodate and hold flexible components. There can be a headspace located above the end face of the flexible component and the inner surface of the end of the top. The flexible component can include an RFID tag. Nevertheless, the presence of the RFID tag can inhibit the sterilization process. Usually, the sterilizing gas passes through the shield assembly from the top of the shield assembly. The RFID tag of U.S. Patent Application Publication No. 2019 / 0217018 blocks the inlet through which the sterilizing gas flows.

[0008] In this context, an object of the present invention is to provide a device that mitigates the above-mentioned drawbacks by enabling long-distance identification of a medical infusion device, without affecting visual inspection, with little risk of removal or damage, without risk of inhibiting the sterilization process, and with limited impact on the manufacturing process.

Means for Solving the Problems

[0009] A first aspect of the present invention is a cover for a medical infusion device, the medical infusion device having a hub portion defined at its distal end, the cover comprising an outer casing formed of a first material, the outer casing having a distal end and a proximal end, the outer casing An inner casing formed of a second material different from the first material and defining a cavity capable of receiving at least a part of the hub portion in a sealed state, the inner casing having a distal end portion and a proximal end portion, and being at least partially inserted into the outer casing and at least partially in contact with the outer casing, and At least one substantially ring-shaped radio frequency identification (RFID) tag embedded in the cover, the ring-shaped RFID tag comprising an RFID chip connected to at least one ring-shaped RFID antenna, Comprising.

[0010] Although not wishing to be bound by any theory, it is believed that the cover of the present invention enables optimized individual traceability of each medical infusion device from the manufacturing process to the final use of the medical infusion device. Moreover, the ring-shaped RFID tag is well protected from removal or external damage that may occur during the packaging, storage distribution, or use of the medical infusion device. Further, since the ring-shaped RFID tag is embedded in the cover, there is no visual impact on the medical infusion device. Furthermore, the insertion of the ring-shaped RFID tag has only a limited impact on the manufacturing process of the cover due to the shape of the RFID tag. Also, the ring-shaped RFID tag is intended to enable remote, and thus easy and long-distance identification of the medical infusion device from the manufacturing process of the cover to the final use or disposal of the medical infusion device. Another advantage of the present invention is that since the RFID tag does not require a direct visual perspective from the reader, the medical infusion device can be read at any time without the need to unpack the medical infusion device, whether it is individually packaged or packaged together with other medical infusion devices such as tabs and / or seal bags. Also, since there is no need to provide additional thickness to the outer wall of the cover, there is no need to change the packaging and storage methods of the medical infusion device.

[0011] According to the present invention, a ring-shaped radio frequency identification (RFID) tag is such that at least one RFID antenna mainly has a substantially ring shape. Preferably, the RFID chip has a substantially rectangular or square shape. Thus, the specific ring shape of the RFID tag, combined with the radial dimension of the RFID tag with respect to the cover and the specific position of the RFID tag, does not prevent a sterilizing gas such as ethylene oxide or steam from passing through the outer casing of the cover during the sterilization step, and the outer casing is impermeable to the sterilizing gas. Further, at least one antenna can be made to a desired length within the ring-shaped structure. This makes it possible to include the RFID tag in the cover without increasing the overall volume of the cover. Ultimately, this makes it possible to increase the level of data transmission to the RFID reader. The longer the antenna, the better the data communication.

[0012] The inner casing of the cover of the present invention comprises an outer wall that is at least partially in contact with the inner wall of the outer casing. The contact is made without an adhesive. Preferably, the outer wall of the inner casing is in contact with the inner wall of the outer casing only partially. In this embodiment, the inner and outer casings can be easily assembled together.

[0013] Preferably, the first material forming the outer casing of the cover of the present invention is more rigid than the second material forming the inner casing of the cover of the present invention.

[0014] Preferably, the first material is thermoplastic and may be polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET), polystyrene (PS), or polycarbonate (PC).

[0015] Preferably, the second material is a deformable material made of a material having elastomeric properties such as a thermoplastic elastomer (“TPE”), rubber, or elastomer. A material having sterilizable elastomeric properties is preferred.

[0016] Advantageously, the cover of the present invention comprises one substantially ring-shaped RFID tag. The ring-shaped RFID tag is embedded in the cover. In other words, the ring-shaped RFID tag is inseparably connected to the cover, and the ring-shaped RFID tag does not need to be removed from the cover. In the present invention, "embedded" means that the ring-shaped RFID tag is overmolded within the cover, or that the ring-shaped RFID is mounted within the cover by adhesive bonding or assembly.

[0017] In one embodiment, the ring-shaped RFID tag is disposed at the distal ends of the outer and inner casings.

[0018] In another embodiment, the ring-shaped RFID tag is disposed in the middle portion of the outer casing.

[0019] In another embodiment, the ring-shaped RFID tag is located at the proximal ends of the outer and inner casings.

[0020] In one embodiment, the ring-shaped RFID tag is disposed on the top inner wall of the outer casing or the top outer wall of the inner casing. Preferably, the ring-shaped RFID tag is disposed on the top inner wall of the outer casing.

[0021] In one embodiment, the ring-shaped RFID tag is embedded within the outer casing, particularly between the lateral inner wall and the lateral outer wall of the outer casing.

[0022] In one embodiment, the ring-shaped RFID tag is embedded within the outer casing and is flush with the lateral inner wall of the outer casing. Preferably, the ring-shaped RFID tag is not embedded within the outer surface of the cover, and in particular, the ring-shaped RFID tag is not embedded within the outer casing.

[0023] In one embodiment, the ring-shaped RFID tag embedded in the cover of the present invention is in the form of a wet inlay, a dry inlay, or a pressure-sensitive label.

[0024] RFID tags, especially RFID wet inlays and RFID dry inlays, can include a substrate made of, for example, paper or polyethylene terephthalate (PET). The RFID tag can be disposed on one side of the substrate. The RFID wet inlay and the RFID dry inlay can further include at least one protective layer on the RFID tag. The protective layer can be silicon-treated paper.

[0025] The RFID wet inlay has an adhesive layer on the opposite side of the substrate and a backing paper such as a silicon liner, so it is described as "wet". The RFID dry inlay is expressed as "dry" because it has no adhesive on the back surface. The pressure-sensitive label is similar to a high-tech sticker.

[0026] In one embodiment, the ring-shaped RFID tag is a low-frequency radio identification (LF-RFID) tag. The low frequency is typically from about 30 KHz to 300 KHz. In this embodiment, the RFID reader can read the LF-RFID tag at a distance of, for example, up to about 10 cm.

[0027] In one embodiment, the ring-shaped RFID tag is a high-frequency radio identification (HF-RFID) tag. The high frequency is typically from about 3 to 30 MHz. In this embodiment, the RFID reader can read the HF-RFID tag at a distance of, for example, about 1 meter.

[0028] In one embodiment, the ring-shaped RFID tag is a high-frequency near-field communication (HF-NFC) tag. The frequency is typically about 13.56 MHz. In this embodiment, the NFC reader can read the HF-NFC tag at a distance of, for example, up to a few centimeters. HF-NFC is different from HF-RFID in that it can be read by an NFC smartphone.

[0029] In one embodiment, the ring-shaped RFID tag is a dual-frequency tag that simultaneously includes HF-NFC and UHF RFID. For example, it can be read by an NFC smartphone or a UHF reader.

[0030] Preferably, the ring-shaped RFID tag is an ultra-high frequency radio frequency identification (UHF-RFID) tag. Ultra-high frequency is typically about 400 - 1000 MHz. In this embodiment, the RFID reader can read the UHF-RFID tag at a distance of, for example, about 15 m. A ring-shaped RFID tag means that at least one antenna has a substantially ring shape.

[0031] In one embodiment, the ring-shaped RFID tag includes at least one antenna having two ends, and each end is connected to a part of the RFID chip. In this embodiment, the RFID tag includes an RFID chip and at least one antenna having a substantially ring shape.

[0032] In another embodiment, the ring-shaped RFID tag includes at least one antenna having two legs each including a first end and a second end, and each first end of the legs is connected to a portion of the RFID chip. Preferably, the second ends of the legs of the RFID antenna do not contact each other. In these embodiments, the shape of the legs is considered to further improve communication between the chip, the antenna of the RFID tag, and the RFID reader.

[0033] In another embodiment, the ring-shaped RFID tag includes at least one antenna having two legs each including a first end and a second end, each first end of the legs is connected to a portion of the RFID chip, and each second end includes a plurality of sub-legs. In this embodiment, the two legs are each in the form of a rake.

[0034] In one embodiment, at least one RFID antenna has a linear form.

[0035] In other embodiments, at least one RFID antenna is made in a plurality of steady steps. For example, the RFID antenna can have two legs having a plurality of steady steps. For example, the steady steps can form a square, triangle, rectangle, or waveform. Preferably, the plurality of steady steps have the same amplitude.

[0036] For example, the RFID antenna can have two legs in a sine wave shape, a straight line shape, or a coil shape. Preferably, when the RFID antenna has two legs in a sine wave shape, both legs of the RFID antenna are made of a plurality of sine waves. For example, when the RFID tag is a UHF-RFID tag, the two legs have a sine wave shape. Also, for example, when the RFID tag is an HF-RFID tag, the two legs have a coil shape. In fact, in these embodiments, the shape of the legs is thought to further improve communication between the chip, the antenna of the RFID tag, and the RFID reader.

[0037] Preferably, the RFID antenna forms a loop between the legs, and the RFID chip is disposed between the loop and the legs of the RFID antenna.

[0038] In one embodiment, the RFID tag is asymmetric, that is, the RFID chip is not disposed equidistant from both ends of the RFID antenna.

[0039] Preferably, the RFID chip is disposed equidistant from both ends of the RFID antenna.

[0040] In one embodiment, the ring-shaped RFID tag includes at least one dipole antenna. The dipole antenna generally consists of two identical conductive antennas such as metal wires or rods connected to the RFID chip.

[0041] A second aspect of the present invention is a medical infusion device comprising a hub portion according to the present invention and a cover.

[0042] A third aspect of the present invention is a method for manufacturing a cover comprising an inner casing and an outer casing according to the present invention, the method comprising:

[0043] A. providing an inner casing and an outer casing, the inner casing defining a cavity capable of receiving at least a part of a hub portion defined at a distal end of a medical infusion device in a sealed state; B. providing at least one ring-shaped RFID tag on the inner casing and / or the outer casing, the ring-shaped RFID tag including an RFID chip connected to at least one ring-shaped RFID antenna; C. assembling the cover by inserting the inner casing into the outer casing such that the RFID tag is embedded within the cover.

[0044] In step A), the inner casing and the outer casing may be manufactured separately. For example, the inner casing and the outer casing may be separately manufactured by molding.

[0045] Preferably, in step B), the ring-shaped RFID tag is provided on the inner casing and / or the outer casing by overmolding, by bonding with an adhesive or by assembly.

[0046] For example, the ring-shaped RFID tag may be embedded within the top inner wall of the outer casing or on the top outer wall of the inner casing by overmolding or by assembly. Preferably, the ring-shaped RFID tag may be embedded within the top inner wall of the outer casing or on the top outer wall of the inner casing by overmolding.

[0047] For example, when the ring-shaped RFID tag is embedded between the inner casing and the outer casing, the ring-shaped RFID tag is mounted between the top inner wall of the outer casing and the top outer wall of the inner casing. For example, the ring-shaped RFID tag can be adhered to the outer wall of the inner casing or the inner wall of the outer casing by bonding with an adhesive or by assembly.

[0048] In step C), the inner casing and the outer casing can be assembled to form the cover of the present invention such that the RFID tag is embedded in the cover.

[0049] The present invention and the advantages arising therefrom will become apparent from the following detailed description taken in conjunction with the accompanying drawings.

Best Mode for Carrying Out the Invention

[0051] Figures 1, 2 and 4 show a medical infusion device 1 such as a syringe having a body 2. The body 2 includes a side wall 3 that forms a reservoir adapted to contain a medical composition 4 to be infused. The medical infusion device 1 further includes a hub portion 5 provided at its distal end 6. The hub portion 5 is partially hollow so as to form a channel 7 in fluid communication with the body 2.

[0052] A needle 8 may be attached to the hub portion 5 of the medical infusion device 1. For example, the needle 8 may be adhered to the hub portion 5 using an adhesive 9. The cover of the present invention is intended to cover the hub portion 5 of the medical infusion device 1 and protect the needle 8.

[0053] The medical infusion device or syringe 1 shown in Figures 1, 2 and 4 may include a plunger rod (not shown in the figures) having a plunger provided at its end. The plunger is slidably moved along the inner surface of the side wall 3 within the body 2 to discharge the medical composition 4 from the body 3 through the channel 7 and thus through the needle 8. The medical composition 4 provided in the medical infusion device 1 may be, for example, a pharmaceutical composition such as a liquid medicine, drug, or vaccine.

[0054] Figs. 1 to 5 are diagrams showing a cover 10 according to an embodiment of the present invention. The cover 10 of the present invention is intended to protect a needle 8 placed on a hub portion 5 of a medical infusion device 1. The cover 10 is intended to be placed on the hub portion 5 of the medical infusion device 1. The cover 10 includes an outer casing 20 and an inner casing 30. The outer casing 20 is typically made of a rigid material, while the inner casing 30, with which the needle 8 is directly engaged when the cover 10 is attached to the hub portion 6 of the medical infusion device 1, is made of a soft material. Preferably, the outer casing 20 is made of polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET), polystyrene (PS), or polycarbonate (PC), more preferably polypropylene. Advantageously, the inner casing 30 is made of a deformable material such as TPE (thermoplastic elastomer). Advantageously, the outer casing 20 includes a partially closed distal end portion and an open proximal end portion. Typically, the distal end portion of the outer casing includes a top wall that may include at least a through hole 24. The through hole 24 may be useful, for example, to allow a sterilizing gas to enter the outer casing. Preferably, the inner casing 30 includes a closed distal end portion and an open proximal end portion. The outer casing 20 may be manufactured to include at least one lock window 21 at its proximal end portion. The lock window defines a through opening and is configured to receive at least a radial lug 31 of the inner casing 30. The radial lug 31 of the inner casing 30 engages with at least one window 21 of the outer casing 20. Typically, the outer casing includes two lock windows 21 that are diametrically opposed. Typically, the inner casing includes two diametrically opposed radial lugs 31, or one radial lug extending over the entire circumference of the outer surface of the inner casing. The outer casing 20 may include an abutting portion 22 located adjacent to the lock window 21 that enables the outer casing 20 to lock the inner casing 20 when the radial lug 31 engages within the lock window 21. The outer casing 20 may be manufactured by overmolding or injection molding.

[0055] The outer casing 20 can comprise a top inner wall 23, which may receive the top outer wall 32 of the inner casing 30.

[0056] The inner casing 30 may also include an internal transverse wall 33 which is intended to at least partially cooperate with the hub portion 5 of the medical infusion device 1 when the cover 10 is placed on the hub portion 5. The internal transverse wall 33 of the inner casing 30 is intended to engage in a sealing manner with the outer surface of the hub portion 5 of the medical infusion device 1.

[0057] In FIGS. 2 to 6, a ring-shaped RFID tag 40 which may be embedded between the inner casing 30 and the outer casing 20 is illustrated. For example, the ring-shaped RFID tag 40 may be embedded in the top inner wall 23 of the outer casing 20. Advantageously, the ring-shaped RFID tag 40 at least partially surrounds a through hole 24 provided in the top wall of the outer casing 20. The ring-shaped RFID tag 40 comprises at least one substantially ring-shaped antenna 40a having two ends E1, E2. Each end E1, E2 may be connected to portions P1, P2 of a rectangular-shaped RFID chip 40b. During sterilization, the sterilization gas can flow easily from the opening 24 through the cover 10. In fact, by combining the particular ring shape of the RFID tag, the radial dimension of the RFID tag with respect to the cover, and the particular position of the RFID tag, the sterilization gas is not impeded from passing through the outer casing of the cover, particularly the opening, during the sterilization step. Furthermore, at least one antenna can be of a desired length within the ring configuration. This makes it possible to include the RFID tag in the cover without increasing the overall volume of the cover. This thus makes it possible to increase the level of data transmission to the RFID reader.

[0058] As shown in FIG. 7, alternatively, the ring-shaped RFID tag 50 can include at least one substantially ring-shaped antenna 50a having two legs L1, L2 each including a first end E1 and a second end E2, and the first ends E1 of each of the legs L1, L2 are connected to portions P1, P2 of the RFID chip 50b. In this example, the second ends E2 of the legs L1, L2 of the RFID antenna 50a are not in contact with each other. The ring-shaped RFID tag 50 may include one RFID antenna 50a having two legs including a plurality of steady steps. For example, the steady steps form a rectangular shape. For example, the plurality of steady steps have the same amplitude. For example, the RFID chip of the RFID tag 50 is disposed equidistant from the ends of both RFID antennas. The ring-shaped RFID tag 50 can preferably include a substrate 51 made of, for example, paper or polyethylene terephthalate (PET).

[0059] The ring-shaped tags 40, 50 may be in the form of a dry inlay or a wet inlay. When the ring-shaped RFID tags 40, 50 are in the form of a wet inlay, the ring-shaped RFID tags are embedded independently of each other between the top inner wall 23 of the outer casing 20 and the top outer wall 32 of the inner casing 30.

[0060] The ring-shaped tags 40, 50 may be, independently of each other, LF-RFID tags, HF-RFID tags or HF-NFC tags. Preferably, the ring-shaped tags 40, 50 may be, independently of each other, HF-RFID tags.

[0061] Currently, RFID tags enable individual traceability of medical containers such as medical infusion devices, particularly from the manufacturing process to use in hospitals, preferably at the end-user's home. HF-NFC tags are typically used by the end user. In one embodiment, the cover includes one substantially ring-shaped HF-RFID tag and one HF-NFC tag.

[0062] Figures 8, 9, 11 and 13 show a medical infusion device 100 comprising a body 101. The body comprises side walls 102 that form a reservoir adapted to contain a medical composition 103 to be infused. The medical infusion device 100 further comprises a hub portion 104 provided at its distal end 105. The hub portion 104 is partially hollow so as to form a channel 106 in fluid communication with the body 101.

[0063] The adapter 110 is intended to be placed at the distal end 105 of the medical infusion device 100, more precisely on the outer surface of the hub portion 104 of the medical infusion device 100.

[0064] The adapter 110 may be configured to be fixed to the medical container 100 at its proximal end and may be in the form of a connection ring configured to receive a cover 120 according to the invention at its distal end. In practice, for using the medical infusion device 100, the cover 120 is removed from the adapter 110 and a connector (not shown), such as a needle hub or a venous line, is placed on the adapter 110 to establish fluid communication between the passage 106 of the medical container 100 and the connector.

[0065] Figures 8 to 13 show the cover 120 according to an embodiment of the present invention. The cover 120 of the present invention is intended to ensure the sterility and integrity of the medical infusion device 100. The cover 120 is intended to be mounted on the adapter 110. The cover 120 includes an outer casing 130 and an inner casing 140. The outer casing 130 is typically made of a rigid material, while the inner casing 140 is made of a soft material. Preferably, the outer casing 130 is made of polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET), polystyrene (PS) or polycarbonate (PC), most preferably polypropylene. Advantageously, the inner casing 140 is made of a deformable material such as TPE (thermoplastic elastomer). Preferably, the outer casing 130 has a closed end portion and an open proximal end portion. Typically, the inner casing 140 has a closed end portion and an open proximal end portion. The outer casing 130 is configured to receive the inner casing 140.

[0066] Figures 9 to 12 show an embodiment in which the ring-shaped RFID tag 150 is embedded in the cover 120. The ring-shaped RFID tag 150 is embedded between the lateral inner wall 131 of the outer casing 130 and the lateral outer wall 132 of the outer casing 130.

[0067] As shown in Figures 9 to 12, the ring-shaped RFID tag 150 may be embedded in the end portions of the outer 130 and the inner casing 140. The ring-shaped RFID tag 150 may include at least one antenna 150a having two end portions E1, E2. Each end portion E1, E2 may be connected to portions P1, P2 of the RFID chip 150b.

[0068] Alternatively, the ring-shaped RFID tag 150 may be embedded in the proximal end portions of the outer casing 130 and the inner casing 140.

[0069] FIG. 13 shows an embodiment in which the ring-shaped RFID tag 160 may be embedded in the middle portion of the outer casing 130, particularly, within the middle portion of the outer casing 130. In this example, the ring-shaped RFID tag 160 is located within the outer casing 130 and is flush with the lateral inner wall 131 of the outer casing 130.

[0070] For example, the ring-shaped RFID tag 160 includes at least one antenna having two legs each including a first end and a second end, and each first end of the legs is connected to a part of the RFID chip, and each second end may include a plurality of sub-legs (not shown). In this example, the two legs are each in the form of a rake (not shown). For example, the RFID chip is disposed at an equal distance from both RFID antenna ends.

[0071] The ring-shaped tags 150, 160 may be in the form of a dry inlay or a wet inlay. When the ring-shaped RFID tags 150, 160 are in the form of a wet inlay or a dry inlay, the ring-shaped RFID tags 150, 160 are respectively embedded between the lateral inner wall 131 of the outer casing 130 and the lateral outer wall 132 of the outer casing 130 by overmolding.

[0072] The ring-shaped tags 150, 160 may be, independently of each other, LF-RFID tags, HF-RFID tags, or UHF-RFID tags. Preferably, the ring-shaped tags 150, 160 may be, independently of each other, HF-RFID tags.

[0073] The cover according to the present invention does not affect visual inspection, has almost no risk of being removed or damaged, and has a limited impact on the manufacturing process, enabling long-distance and high-efficiency individual identification of medical infusion devices.
