Description

Technical Field

[0001] This disclosure relates in general to a drug delivery device, and more particularly to a drug container housing for containing a drug container. Background Technology

[0002] Many medical conditions require injections. Currently, numerous different injection devices exist, including various types of pen injectors, auto-injectors, and infusion devices for large-volume injections. While many of these devices have brought significant improvements to the management of many medical conditions, various limitations remain in current technology. Of particular note are the difficulties faced by patients requiring frequent injections. In considering these issues, the applicant has recognized various developments that can help improve the drug delivery devices currently on the market, such as those addressing multi-drug scenarios where the administration of medications in a predetermined order is important, as will be elaborated below. Medications may be associated with advanced treatments in a home setting (e.g., oncology). Medications and prescriptions are determined by a physician or pharmacist, who submits the prescription to the pharmacy. The pharmacist prepares and packages the medication for the patient. However, current technical procedures require patients to identify and correct the administration of medications. Summary of the Invention

[0003] The purpose of this disclosure is to provide a drug container shell for accommodating a pharmaceutical container that solves or at least mitigates the problems of the prior art.

[0004] According to a first aspect of this disclosure, a drug container housing for containing a pharmaceutical container is provided, the drug container housing comprising: a designated portion including a set of markings to indicate the location of an RFID tag; and an RFID tag attached to the designated portion according to the set of markings, the RFID tag including processing circuitry and circuit loops, each circuit loop having a circuit path aligned with a corresponding marking of the designated portion, wherein penetration of the markings results in a break in the corresponding circuit loop.

[0005] The embodiments of this disclosure advantageously provide a pharmaceutical information system that can be entered via manually penetrating tags. This eliminates the need for users (e.g., patients) to rely on written instructions. Instead, pharmacists or pharmaceutical providers can directly enter information into RFID tags on the outer shell of the medication container.

[0006] An alternative is to write the sequence number directly into the RFID chip electronically, which requires pharmacies to invest in hardware and software capabilities. The high investment costs for such systems and their validation would be very high, and it would be difficult to justify their suitability for specific device applications.

[0007] Furthermore, markings on the outer shell of the drug container aid in the location of RFID tags. Due to the design and structure of the tags, breaking the corresponding circuit loops can be achieved more easily.

[0008] In this disclosure, when the term "distal direction" is used, it refers to a direction pointing away from the dose delivery site during use of the drug delivery device. When the term "distal portion / distal end" is used, it refers to the portion / end of the delivery device or a portion / end of an assembly of the delivery device that is positioned furthest from the dose delivery site during use of the drug delivery device. Correspondingly, when the term "proximal direction" is used, it refers to a direction pointing toward the dose delivery site during use of the drug delivery device. When the term "proximal portion / proximal end" is used, it refers to the portion / end of the delivery device or a portion / end of an assembly of the delivery device that is positioned closest to the dose delivery site during use of the drug delivery device.

[0009] In addition, the terms “longitudinal,” “longitudinally,” “axially,” and “axial” refer to the direction of extension from the proximal end to the distal end, typically along the longest extension direction of the device or its components.

[0010] Similarly, the terms "lateral," "transverse," and "laterally" refer to a direction that is approximately perpendicular to the longitudinal direction.

[0011] Furthermore, the terms "circumferential," "circumferential," and "circumferentially" refer to the circumference or circumferential direction 301 relative to axis 102, which is typically a central axis extending in the longest extension direction of the device and / or assembly. Similarly, "radial" or "radiallyly" refers to the direction 302 extending radially relative to the axis, and "rotational," "rotational," and "rotationally" refer to rotation relative to the axis.

[0012] According to one implementation, pharmaceutical information can be read from the RFID tag, where the pharmaceutical information depends on which corresponding circuit loop breaks. Advantageously, the RFID tag can contain predetermined information, such as a unique identifier and other information writable into the RFID tag's memory. Manipulating the RFID tag provides the ability to input information into the RFID tag without requiring a verified RFID writing system. Such RFID writing systems are expensive and cumbersome to implement.

[0013] According to one implementation, the RFID tag may include a visual tag to guide pharmacists through the correct markings to enter the desired medication information. Advantageously, the visual tag helps users penetrate the correct markings to enter the expected medication information. The visual tag may be printed on a separate layer of the RFID tag, which is attached to a circuit layer including circuit loops.

[0014] In some implementations, tags or tag pieces can be added to the top of RFID tags and visual tags to lock in the possibility of penetrating and breaking the remaining circuit loop.

[0015] According to one embodiment, the medication information may include the order of the current medication container in the current drug sequence. This order could be, for example, the current medication container being the first, second, third, etc., medication container in the current sequence. This assists the user when injecting or administering medication in the current order. The medication delivery device can read RFID tags to check if the correct medication container shell has been delivered.

[0016] According to one implementation scheme, the drug information may advantageously include the total number of injections to be administered in the current drug sequence.

[0017] According to one embodiment, the marking may include a set of holes or voids in the outer shell of the drug container. By having holes or voids in the material of the drug container shell, the amount of force required to penetrate the marking is reduced. A tool used to penetrate the marking thus enters or punctures the holes or voids.

[0018] According to one embodiment, the set of markings may include a set of weak points in the outer shell of the drug container. The weak points may be made of a material different from the rest of the drug container shell, such as voids or holes filled with a weaker material that is more easily penetrated than the overall material of the drug container shell. Another embodiment would be a label tab containing tear-away circuitry.

[0019] According to one implementation, the RFID tag can be attached to the outer shell of the drug container using an adhesive. That is, the RFID tag can be a flexible, multi-layered tag that is glued to the outer shell of the drug container in designated sections.

[0020] According to one implementation, the drug container shell can be installed in a drug delivery device that includes an RFID reader.

[0021] According to a second aspect, a drug delivery device is provided, the drug delivery device being configured to receive a drug container housing according to any one of the embodiments described herein, the drug delivery device including an RFID reader, the RFID reader including processing circuitry configured to: read drug information and compare the read drug information with drug information stored on the device, and provide an instruction for the comparison to a user via a user interface.

[0022] The further effects and features of the second aspect of this disclosure are largely similar to those described above in conjunction with the first aspect of this disclosure.

[0023] According to a third aspect, an RFID tag configured to be attached to the outer shell of a drug container is provided, the RFID tag comprising: a processing circuit; and at least one circuit loop, wherein an end portion of each circuit loop is electrically connected to the processing circuit, the circuit loops being configured to be broken by penetrating the RFID tag with an external tool to input drug information, and the processing circuit being configured to detect whether the circuit loops are intact or broken.

[0024] According to one implementation, a break in the circuit loop can provide drug information to the processing circuit.

[0025] According to one implementation, the RFID tag may include a visual tag to guide the user (i.e., the pharmacist) through the correct location to enter the desired medication information.

[0026] According to one implementation, the drug information may include the order in which the current drug container is located in the current drug sequence.

[0027] According to one implementation, the drug information may include the total number of injections to be administered in the current drug sequence.

[0028] The further effects and features of the second aspect of this disclosure are largely similar to those described above in conjunction with the first and second aspects of this disclosure.

[0029] Generally, unless otherwise expressly defined herein, all terms used in the claims shall be interpreted according to their ordinary meaning in the art. Unless otherwise expressly stated, all references to “a / an / the component, device, assembly, part, etc.” shall be openly interpreted as referring to at least one instance of a component, device, assembly, part, etc. Attached Figure Description

[0040] The inventive concept will now be described more fully below with reference to the accompanying drawings, in which exemplary embodiments are illustrated. However, the inventive concept can be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided by way of example so that this disclosure will be thorough and complete, and will fully convey the scope of the inventive concept to those skilled in the art. Throughout the specification, similar reference numerals refer to similar elements.

[0041] Figure 1A An example of a drug delivery device 1, such as an autoinjector, according to an embodiment of the present disclosure is shown. The drug delivery device 1 is configured to dispense a drug from a drug container to a user at a dose delivery site via a drug delivery member such as a needle. The drug delivery device 1 extends from a proximal end 1a to a distal end 1b relative to an axis 102.

[0042] The drug delivery device 1 includes a housing 3 having a window 4. The housing 3 has a proximal end 3a and a distal end 3b. A needle guard 6 configured to cover the needle extends from the proximal end 3a of the housing 3.

[0043] The medicine container is placed inside the housing 3, and the medicine is discharged from the medicine container under the action of the spring-loaded plunger.

[0044] Figure 1B Another example of a drug delivery device 1 for an autoinjector, such as an injection device, according to an embodiment of the present disclosure is shown. The drug delivery device 100 is configured to dispense a drug from a drug container to a user at a dose delivery site via a drug delivery member, such as a needle 2. The drug delivery device 100 extends from a proximal end 1a to a distal end 1b relative to an axis 102.

[0045] The drug delivery device 1 includes a housing 3 and is capable of being connected to a drug container housing 4 having a proximal end 4a and a distal end 4b.

[0046] In this example, the drug container housing 4, which may be a disposable box, is connected to the infusion set 7. The infusion set includes a flexible tube 8 that connects to a through-hole in the disposable box 4 at its proximal end 4a. At the other end of the tube 8 is a needle 2 attached via a liner 9. The infusion set 7 is optional for embodiments of this disclosure.

[0047] The disposable box 4 is adapted to contain a pharmaceutical container, which may have different volumes, for example, in the range of about 1 ml to about 10 ml.

[0048] The drug delivery device 1 includes a receiving interface 11 configured to receive a disposable box and lock the disposable box to the proximal end 1a of the drug delivery device 1.

[0049] The outer shell of the drug container 4 is adapted to be a drug container for containing and holding the drug.

[0050] Auto-injectors and other products used to deliver medications to users provide an efficient means of administering drugs. In cases of multiple drug administration, new complexities are added. In particular, user involvement increases to ensure that drugs are injected or administered in the correct order. In the prior art, the most common solution is to communicate the drug delivery sequence to the user through verbal instructions and / or written instructions and labels. However, this solution relies on the user's ability to correctly understand and follow the instructions.

[0051] This paper proposes a drug container shell and RFID tag that at least partially mitigate the shortcomings of the prior art.

[0052] One advantage of the proposed solution is that it eliminates the need for patient-dependent instructions, the need for pharmacy-designed IT systems with APIs that remotely communicate drug type and sequence to drug delivery systems (from different manufacturers), and the need for direct human programming of the device system. Direct human programming of the device system would require patients to send or bring the system to the pharmacy before each round of administration. Designing an IT system with an API in the pharmacy would require reliable wired or wireless remote communication between the device system and the pharmacy backend.

[0053] Figure 2A A drug container housing 10 is schematically illustrated. The drug container housing 10 is adapted to contain and hold a drug container. The drug container housing 10 can be provided in various forms, such as a box, a plastic container, or as... Figure 1B The disposable box 4 shown is used to hold the medicine container.

[0054] The drug container housing 10 includes a designated portion 12 that includes a set of markings 14 (only one of which is numbered) to indicate the location of an RFID tag. In this example embodiment, the drug container housing 10 includes six markings 14.

[0055] Marking 14 may include a set of holes or voids in the drug container housing 10. That is, pre-formed holes or voids in the overall material of the drug container housing 10 may form markings. Markings may also include visual indications of the location of the holes in the voids.

[0056] In other embodiments, the set of markings 14 may include a set of weak points in the drug container shell 10. The weak points can be penetrated, for example, by the force exerted by a user (i.e., a pharmacist) inserting a pen into the markings.

[0057] Go to Figure 2B The drug container housing 10 also includes an RFID tag 16 attached to a designated portion 12 according to the set of markings 14. The RFID tag includes processing circuitry 18 and circuit loops 20, each circuit loop having a circuit path aligned with a corresponding marking 14 of the designated portion 12. Figure 2A In the middle, a housing 10 without the RFID tag 16 is added to show how the circuit loop 20 is aligned with the tag 14.

[0058] The alignment between the marker 14 and the corresponding circuit loop 20 is such that if the marker 14 is penetrated through the layer of the RFID tag 16, the corresponding circuit loop 20 breaks. Therefore, penetration of the marker 14 results in the breakage of the corresponding circuit loop 20.

[0059] Figure 2C An example is a medicine container shell 10 with an RFID tag 16, but it is also equipped with a visual tag 22 to guide users such as pharmacists through the correct mark 14 to enter the desired medicine information.

[0060] In this example, the label includes the order of the current medication container in the current medication sequence in the bottom row, and the total number of injections to be administered in the current medication sequence in the top row. In other words, in order to program the processing circuit 18 with medication information, the pharmacist uses the label 22 to penetrate the correct markings 14 to input the number of injections and the order in the injection sequence for each medication container.

[0061] The drug container housing 10 can be installed in a drug delivery device including an RFID reader. Drug information can be read from the RFID tag 16, where the drug information depends on which corresponding circuit loop 20 is broken.

[0062] The processing circuit assesses whether the circuit loop is intact or broken when powered on. Depending on whether the circuit loop is connected, i.e., whether it is intact, the processing circuit reads different resistances or voltages, which will also generate different signals, i.e., high or low, or 1 or 0.

[0063] Figure 3 The following example illustrates the signals read by processing circuit 18 based on the state of circuit loop 20. Each loop in the loop, denoted as AF, is associated with a single dose of medication information. For illustration, let's assume that circuit loops A, B, and C refer to the total number of injections, such as one, two, and three, respectively. Furthermore, circuit loops E, F, and G may refer to the sequence of administration of a specific medication, i.e., the first, second, or third, respectively. If a circuit loop is broken, a high signal, the digit 1, is recorded, and if a circuit loop is intact, a low signal, the digit 0, is recorded. In this particular example, if processing circuit 18 reads circuit loop 20, the medication information will be that the total number of injections in the current sequence is 3, and the current medication is the second medication in the sequence. This information is received when the medication delivery device reads RFID tag 16 and can be checked against previous injections to ensure that the correct medication in the current sequence is loaded into the medication delivery device.

[0064] Figure 4 This is an exploded view of the drug container housing 10. The drug container housing includes a designated portion 12 located on the body 25 of the drug container housing 10. In the designated portion 12, a set of markings 14 may be provided as a gap, hole, or weak point that can be penetrated by a point tool.

[0065] In a separate layer, the RFID tag 16 is attached to the drug container housing body 25, for example, by adhesive. The RFID tag 16 is attached to a designated portion 12, which serves as the bottom layer. The RFID tag 16 includes processing circuitry 18 and a circuit loop 20 electrically connected to the processing circuitry 18. The circuit loop 20 reaches the tag 14 such that a portion of the circuit loop aligns with the tag. The processing circuitry 18 is configured to detect whether the circuit loop is intact or broken.

[0066] In the top layer, a visual tag 22 is arranged, which is either part of an RFID tag (i.e., printed on the RFID tag) or as a separate layer attached to the RFID tag 16. Tag 22 guides the pharmacist through the correct location to enter the desired medication information. Tag 22 typically includes written information instructing the user.

[0067] exist Figure 4 In the diagram, circuit loop 20 is shown as a planar circuit located in a horizontal plane (i.e., in a single plane parallel to the main plane of RFID tag 16). In other possible embodiments, the circuit loop may be a dual-plane circuit loop with vertical connections.

[0068] Figure 5 Possible sequences of embodiments using this disclosure are illustrated. As described above, a drug container housing 10 is provided. A user (typically a pharmacist or similar person) uses a pointed tool (27) to penetrate the correct mark 14, guided by a visual tag 22, based on the desired drug information. The visual tag 22 is located in the top layer, and the mark 14 is located in the bottom layer, with an RFID tag sandwiched between the mark 14 and the visual tag 22.

[0069] In this scenario, the total number of containers is 2, and the current container 10 is the first in the sequence. Penetration of tag 14 causes circuit loop 20 corresponding to the total number of containers being 2 and the current container 10 being the first in the sequence. The processing circuit 18 of RFID tag 16 can access instructions corresponding to a given drug information for a given circuit loop.

[0070] Figure 6 An example is illustrated of a drug delivery device 30 configured to receive a drug container housing 10. The drug delivery device (which can be of various types and is not limited to auto-injectors) includes an RFID reader 32, which includes processing circuitry 34 configured to read drug information from an RFID tag 16.

[0071] Therefore, the processing circuit 34 reads the current container's order in the current drug treatment sequence and the total number of injections in the current sequence.

[0072] The processing circuit 34 can compare the read drug information with stored drug information (e.g., related to a previously administered injection), or compare the unique identifier of the current container with a pre-stored ID associated with the drug to be administered, and ensure that the same container is not inserted twice.

[0073] The processing circuitry 34 provides a comparison instruction to the user via a user interface 36. The user interface 36 may be, for example, an audio, visual, or tactile interface. Thus, the device 30 can read whether the inserted container 10 is in the correct order by comparing it with the information given by the tag and with data from previous injections that has been processed and stored locally in the device 30 system.

[0074] The embodiments of this disclosure can be applied to various drug delivery devices. In one possible specific embodiment, the drug delivery device may be an autoinjector.

[0075] Drug delivery devices (such as autoinjectors) typically include a variety of other components. For example, a sensor unit that identifies drug delivery events, such as insertion of the needle into an attachment portion, for example, a liner, the start of injection, and the end of the drug delivery operation; a memory unit configured to store recorded data during the drug delivery operation; a connectivity unit configured to transmit the stored data directly to a smart device or network; a processing unit configured to control the entire system and process the data before transmission; and / or a user interface unit configured to provide feedback to the patient, such as status LEDs, haptic feedback, and / or audio feedback.

[0076] When the medication delivery device is placed into the attachment portion, sensors inside the pad are configured to recognize events and provide feedback to the patient via tactile / visual or audio elements.

[0077] Once medication delivery is complete, the sensors are configured to recognize the event and provide feedback to the patient again. Furthermore, the collected data is stored in a memory unit and can be transmitted to a smart device / network via a connectivity unit after the medication delivery event has concluded.

[0078] The sensor can be one or a combination of the following: mechanical switch, Hall effect sensor, accelerometer.

[0079] Mechanical switches, Hall effect sensors, or accelerometers can be used to detect when a needle is inserted into an injection port.

[0080] Accelerometers can be used to detect drug delivery events.

[0081] Possible wireless communication methods include Bluetooth and cellular networks.

[0082] Bluetooth connectivity requires the smart device to send its stored data to the network, and in the case of a two-way connection, it requires pairing between the pad and the smart device before the support pad can be used. However, it is a cheaper alternative and requires less space on the PCB. One-way connectivity does not require pairing.

[0083] Cellular networks do not require any pairing process and can be used as plug-and-play devices without prior setup, but they are more expensive and require more space on the PCB.

[0084] Depending on the product requirements, either of these two technologies can be used.

[0085] Such processing units or circuits may include logic circuitry or control units, which may include microprocessors, microcontrollers, programmable digital signal processors, or other programmable devices. Processing circuitry may also, or alternatively, include application-specific integrated circuits (ASICs), programmable gate arrays (PGAs) or programmable array logic, programmable logic devices, or digital signal processors. Where the processing circuitry includes programmable devices such as microprocessors, microcontrollers, or programmable digital signal processors described above, the processor may also include computer-executable code that controls the operation of the programmable device.

[0086] The drug delivery device described herein can be used to treat and / or prevent one or more of many different types of diseases. Exemplary diseases include, but are not limited to: rheumatoid arthritis, inflammatory bowel disease (e.g., Crohn's disease and ulcerative colitis), hypercholesterolemia, diabetes (e.g., type 2 diabetes), psoriasis, migraine, multiple sclerosis, anemia, lupus, atopic dermatitis, asthma, nasal polyps, acute hypoglycemia, obesity, anaphylactic reactions, and allergic reactions. Exemplary drug types that may be included in the drug delivery device described herein include, but are not limited to: antibodies, proteins, fusion proteins, peptides, polypeptides, PEGylated proteins, protein fragments, protein analogs, protein variants, protein precursors, and / or protein derivatives. Exemplary drugs that may be included in the drug delivery device described herein include, but are not limited to (non-limiting examples of related diseases in parentheses): etanercept (rheumatoid arthritis, inflammatory bowel disease (e.g., Crohn's disease and ulcerative colitis)), evolocumab (hypercholesterolemia), exenatide (type 2 diabetes), secukinumab (psoriasis), eleneumab (migraine), alicurumab (rheumatoid arthritis), methotrexate (rheumatoid arthritis), tocilizumab (rheumatoid arthritis), interferon beta-1a ( Multiple sclerosis), sumatriptan (migraine), adalimumab (rheumatoid arthritis), dapoxetine alpha (anemia), belimumab (lupus), pegylated interferon beta-1a' (multiple sclerosis), thalidomide (rheumatoid arthritis), semaglutide (type 2 diabetes, obesity), dupilumab (atopic dermatitis, asthma, nasal polyps, allergic reactions), glucagon (acute hypoglycemia), adrenaline (allergic reactions), insulin (diabetes), atropine and vedolizumab (inflammatory bowel disease (e.g., Crohn's disease and ulcerative colitis)). Pharmaceutical formulations, including but not limited to any of the drugs described herein, are also considered for use in the pharmaceutical delivery devices described herein, such as pharmaceutical formulations containing the drugs listed herein (or pharmaceutically acceptable salts of drugs) and pharmaceutically acceptable carriers. Pharmaceutical formulations containing the drugs listed herein (or pharmaceutically acceptable salts of drugs) may include one or more other active ingredients, or may be the only active ingredient present.

[0087] The foregoing description primarily refers to several examples to illustrate the inventive concept. However, as will be readily understood by those skilled in the art, other embodiments besides those disclosed above may also be within the scope of the inventive concept as defined in the appended claims.
