The present disclosure relates generally to a drug storage and dispensing system. More particularly, the present disclosure relates to a drug storage and dispensing system for pre-filled containers.
Conventional syringes are well known in the medical field to be used in connection with a vial of a medication, where the user collects or draws the fluid into the syringe immediately prior to injection and delivery of the fluid to the patient. Commonly, hypodermic syringes may be packaged as “pre-filled” devices, wherein the syringe is pre-filled with medication prior to being packaged and delivered to the patient. In this manner, the need for the user to fill the device prior to injection is eliminated, thereby saving time and maintaining consistent volumes for delivery.
However, packaging of such pre-filled syringes tends to be bulky and difficult to ship and store. A pre-filled syringe is typically packaged with the opening at the front end of the barrel including a cap thereover and with the plunger rod retracted out of the back end of the syringe barrel, with the fluid pre-filled within the syringe barrel. Such packaging creates an elongated package that can be awkward for shipping and storage.
Pre-filled syringes and pre-filled metered dose syringes are often filled with fluids, such as a medication, at a production facility, packaged, and then shipped to a medical facility. Once at the facility, these syringes are often placed in controlled storage and/or locked cabinets to reduce theft of the syringes themselves and/or of the contents of these syringes. The space within these controlled storage locations is often limited, thus there is a need for a storage format for pre-filled drug containers that minimizes the space occupied by such containers in the cold chain. Cold chain space is one of the inhibitors against conversion to pre-filled containers especially in developing regions.
Further, drug containers need to include information to help medical professionals identify the contents of the drug containers. Errors such as giving an incorrect medication or an incorrect dose can easily be made if the contents of the drug containers cannot be positively identified from the point of time that a medication is transferred to a drug container up to the moment of its administration.
The results of missed and unintended medication include adverse effects to patients and significant costs to the healthcare industry. Potential causes for these errors include unclear drug container contents due to unlabeled or poorly labeled drug containers and poor record keeping of which drugs were administered and the concentration and quantity of the administered drug.
Identifying the content of a drug container based on the appearance of that content is unreliable. Visual identification of the medication is very difficult since several of the medications are identical or nearly identical in appearance.
Furthermore, the protection of used needle tips of a syringe is important to reduce the risk of incurring an accidental needle-stick wound. With concern about infection and transmission of diseases, methods and devices to enclose the used needle have become very important and in great demand.
The present disclosure provides a drug storage and dispensing system having a packaging unit and an injection device for pre-filled containers having a needle shield and containing a medication. The drug storage and dispensing system of the present disclosure provides for drug administration while minimizing the space occupied by such containers in the cold chain. The packaging unit of the drug storage and dispensing system includes a container holding portion adapted to automatically remove the needle shield of a pre-filled container upon removal of the pre-filled container from the packaging unit. In this manner, the drug storage and dispensing system minimizes the risk of a needle-stick injury, as a healthcare worker does not have to manually remove the needle shield. The injection device of the drug storage and dispensing system provides a novel way of auto-disabling a container, such as a syringe, as a plunger rod is not engaged with the container until the container is actually used. The drug storage and dispensing system provides for a reduction in the number of steps required to perform an injection, and thus a productivity and efficiency gain in mass immunization campaigns. The drug storage and dispensing system provides an automated and secure way to record, store, and transmit the information relative to each injection. The drug storage and dispensing system also provides real-time reconciliation of patient ID, vaccine container ID, vaccination location and time, and the ability to transmit the above information in real-time to a central repository. The drug storage and dispensing system of the present disclosure is especially useful in a pandemic situation where timely and frequent reports of immunization progress over a large population are required.

The plunger rod 64 may be attached to the injection device 16 and movably disposed within the injection device 16. The plunger rod 64 may be permanently attached to the injection device 16 or may be inserted in the injection device 16 by a healthcare worker before each syringe pick-up. In use, a healthcare worker may secure or snap the injection device 16 onto a selected syringe 100 and activate the injection device 16 by pushing an actuation button that deploys the plunger rod 64 and secures or screws it to a portion of the syringe 100. In some embodiments, the plunger rod 64 may be a reusable part. In other embodiments, the plunger rod 64 may be a disposable part.
The injection device 16 is a smart device and can capture, store, and transmit information about its usage. The injection device 16 is equipped with an on-board electronic module comprising a non-volatile memory that can record and store container unique identification information, as well as time stamping information relative to the usage of the pre-filled container 12. The injection device electronic module is also equipped with a global positioning system (GPS) receiver that can record and store latitude and longitude coordinates of usage location. When used indoor, the injection device electronic module is compatible with existing indoor positioning systems using triangulation from wireless signal receivers.
The injection device electronic module is also equipped with a wireless communication module able to establish distant communication by way of one or several of the following methods: near field communication (NFC), Bluetooth low energy (BLE), Wi-Fi, ZigBee, and/or GSM. The injection device electronic module comprises an embedded piece of software which can encrypt the collected information prior to its transmission. The information collected by the injection device can therefore be securely transmitted to a distant recipient by any of the above means. Examples of recipients are: a smartphone, a tablet, and/or a data management platform. In order to visualize transmitted data, application software is developed for all of the above hardware platforms. In case the information is sent to a distant data management platform, the visualization can happen either on a smartphone, a tablet, or a web portal that can also be accessed from an internet-connected computer.
In one embodiment, the injection device could incorporate a motorized-darting mechanism that inserts the selected syringe 100 into the skin surface of a patient at the right pre-set depth. The pre-set depth of insertion is derived from reading the syringe identifier that bears information on the type of injection associated with the syringe.

As discussed above, the plunger rod 64 is attached to the injection device 16. In use, a healthcare worker may secure or snap the injection device 16 onto a selected syringe 100 and activate the injection device 16 by pushing an actuation button that deploys the plunger rod 64 and secures or screws it to a portion of the syringe 100. The healthcare worker may then remove the selected syringe 100 from the tub member 20 of the packaging unit 14 and proceed with the injection. As previously discussed, the needle shield 102 is automatically removed and remains inside the nest member 22 when removing the selected syringe 100 from the packaging unit 14.
As discussed above, the syringe may include a unique identifier that the injection device 16 can read the information contained therein and either store it in its on-board non-volatile memory, or transmit it to a nearby smartphone or to a distant data management system. Similarly, prefilled containers may be equipped with sensors such as temperature/humidity or shock/abuse sensors. Signals from those sensors can be read by the injection device 16 upon pick-up. If an abnormal condition is detected, an indicator present on the injection device 16 will alert the user and an optional interlock can prevent from proceeding with the injection. Once the syringe is picked-up and no abnormal container condition is detected, the healthcare worker proceeds with the injection using the injection device 16.
As described above, the injection device 16 allows for automatic injection of the medication from a selected pre-filled container 12. With the injection device 16 engaged with a respective pre-filled container 12, the injection device 16 is adapted to automatically actuate a plunger rod 64 to expel the medication from the respective pre-filled container 12.
The injection completion can optionally be sensed by the injection device 16, and the corresponding event can either be stored in its on-board non-volatile memory or transmitted to a nearby smartphone or to a distant data management system.
Once injection is completed, a safety mechanism is triggered so that the sharp tip 129 of the cannula 128 cannot be accessed, thus preventing needle-associated injuries. For example, referring to
The drug storage and dispensing system 10 of the present disclosure can be used either in a traditional healthcare setting or outside of a traditional healthcare setting to deliver drugs on demand in a safe and quick manner. The drug storage and dispensing system 10 can also be used by patients suffering from chronic diseases who self-administer their injectable medication.
The drug storage and dispensing system 10 of the present disclosure is especially useful when used to perform vaccinations. Vaccination campaigns can be performed in a traditional healthcare setting, e.g., a doctor's office, hospitals, clinics, minute clinics, pharmacies, vaccination center, or similar settings, or in non-traditional settings, e.g., retail outlets such as supermarkets, schools, or offices, or in no particular setting and directly in contact with the targeted population as it is often the case in developing countries.
Pandemic situations require a medical practitioner to be able to vaccinate a large number of people in a very short amount of time. In all non-traditional vaccination settings, the drug storage and dispensing system 10 of the present disclosure is especially useful for the following reasons: (1) the drug storage and dispensing system 10 provides a faster and safe way of vaccinating more people per unit of time; (2) the drug storage and dispensing system 10 provides a means to optimize cold chain space by offering a denser packaging compared to other packaging systems for pre-filled containers; and (3) the drug storage and dispensing system 10 provides an automated capture and real-time transmission of vaccination data, thus enabling the precise tracking of vaccination coverage at a population level or accurate information in an individual vaccination log or electronic medical record at an individual level.
The drug storage and dispensing system 10 is envisioned to be a part of a novel service of an on-demand, mobile vaccination system. People wishing to be vaccinated can place their order online after responding to a short questionnaire on their current health status. Dispatching units that may be housed in nearby pharmacies would then prepare and group orders coming from their area of responsibility. Orders could then be loaded on a van or truck driven by a healthcare worker who goes on a vaccine delivery. A delivery itinerary and schedule could be optimized by a specific software and updated on-the-fly to account for any last minute change requests by a customer.
The injection device 200 of the drug storage and dispensing system 10 provides for a smart injection assist device that is used to perform drug administration together with a pre-filled drug container 12.

Examples of recipients are: a smartphone, a tablet, and/or a data management platform. In order to visualize transmitted data, application software is developed for all of the above hardware platforms. In case the information is sent to a distant data management platform, the visualization can happen either on a smartphone, a tablet, or a web portal that can also be accessed from an internet-connected computer.
As discussed above, the container 12 may include a unique identifier, e.g., a barcode 290, that the injection device 200 can read the information contained therein and either store it in its on-board non-volatile memory, or transmit it to a nearby smartphone or to a distant data management system, e.g., computer 500. Similarly, prefilled containers may be equipped with sensors such as temperature/humidity or shock/abuse sensors. Signals from those sensors can be read by the injection device 200 upon pick-up. If an abnormal condition is detected, an indicator present on the injection device 200 will alert the user and an optional interlock can prevent from proceeding with the injection. Once the container is picked-up and no abnormal container condition is detected, the healthcare worker proceeds with the injection using the injection device 200.

Next, the scan assembly 216 (
The scan assembly 216 of the injection device 200 allows the injection device 200 to be a smart device that can capture, store, and transmit information about its usage. In one embodiment, the injection device 200 is equipped with an on-board electronic module comprising a non-volatile memory that can record and store container unique identification information, as well as time stamping information relative to the usage of a pre-filled container 12. The injection device electronic module is also equipped with a global positioning system (GPS) receiver that can record and store latitude and longitude coordinates of usage location. When used indoor, the injection device electronic module is compatible with existing indoor positioning systems using triangulation from wireless signal receivers.

In one embodiment, the injection device 200 could incorporate a motorized-darting mechanism that inserts the selected syringe into the skin surface of a patient at the right pre-set depth. The pre-set depth of insertion is derived from reading the syringe identifier that bears information on the type of injection associated with the syringe.
In one embodiment, as discussed above, the syringe or container may include a unique identifier that the injection device 200 can read the information contained therein and either store it in its on-board non-volatile memory, or transmit it to a nearby smartphone or to a distant data management system. Similarly, prefilled containers may be equipped with sensors such as temperature/humidity or shock/abuse sensors. Signals from those sensors can be read by the injection device 200 upon pick-up. If an abnormal condition is detected, an indicator present on the injection device 200 will alert the user and an optional interlock can prevent from proceeding with the injection. Once the syringe is picked-up and no abnormal container condition is detected, the healthcare worker proceeds with the injection using the injection device 200.
The injection completion can optionally be sensed by the injection device 200, and the corresponding event can either be stored in its on-board non-volatile memory or transmitted to a nearby smartphone or to a distant data management system.
The drug storage and dispensing system 10 of the present disclosure can be used either in a traditional healthcare setting or outside of a traditional healthcare setting to deliver drugs on demand in a safe and quick manner. The drug storage and dispensing system 10 can also be used by patients suffering from chronic diseases who self-administer their injectable medication.
The drug storage and dispensing system 10 of the present disclosure is especially useful when used to perform vaccinations. Vaccination campaigns can be performed in a traditional healthcare setting, e.g., a doctor's office, hospitals, clinics, minute clinics, pharmacies, vaccination center, or similar settings, or in non-traditional settings, e.g., retail outlets such as supermarkets, schools, or offices, or in no particular setting and directly in contact with the targeted population as it is often the case in developing countries.
As described above, the injection device 200 allows for automatic injection of a medication from a selected pre-filled container 12. With the injection device 200 engaged with a respective pre-filled container 12, the injection device 200 is adapted to automatically actuate a plunger rod 264 to expel the medication from the respective pre-filled container 12.
In one embodiment, the injection completion can optionally be sensed by the injection device 200, and the corresponding event can either be stored in its on-board non-volatile memory or transmitted to a nearby smartphone or to a distant data management system.
Once injection is completed, a safety mechanism is triggered so that a sharp tip 129 of a cannula 128 cannot be accessed, thus preventing needle-associated injuries. For example, referring to

The drug storage and dispensing system 10 can also be used by patients suffering from chronic diseases who self-administer their injectable medication.
The drug storage and dispensing system 10 of the present disclosure is especially useful when used to perform vaccinations. Vaccination campaigns can be performed in a traditional healthcare setting, e.g., a doctor's office, hospitals, clinics, minute clinics, pharmacies, vaccination center, or similar settings, or in non-traditional settings, e.g., retail outlets such as supermarkets, schools, or offices, or in no particular setting and directly in contact with the targeted population as it is often the case in developing countries.
Pandemic situations require a medical practitioner to be able to vaccinate a large number of people in a very short amount of time. In all non-traditional vaccination settings, the drug storage and dispensing system 10 of the present disclosure is especially useful for the following reasons: (1) the drug storage and dispensing system 10 provides a faster and safe way of vaccinating more people per unit of time; (2) the drug storage and dispensing system 10 provides a means to optimize cold chain space by offering a denser packaging compared to other packaging systems for pre-filled containers; and (3) the drug storage and dispensing system 10 provides an automated capture and real-time transmission of vaccination data, thus enabling the precise tracking of vaccination coverage at a population level or accurate information in an individual vaccination log or electronic medical record at an individual level.
The drug storage and dispensing system 10 is envisioned to be a part of a novel service of an on-demand, mobile vaccination system. People wishing to be vaccinated can place their order online after responding to a short questionnaire on their current health status. Dispatching units that may be housed in nearby pharmacies would then prepare and group orders coming from their area of responsibility. Orders could then be loaded on a van or truck driven by a healthcare worker who goes on a vaccine delivery. A delivery itinerary and schedule could be optimized by a specific software and updated on-the-fly to account for any last minute change requests by a customer.
While this disclosure has been described as having exemplary designs, the present disclosure can be further modified within the spirit and scope of this disclosure. This application is therefore intended to cover any variations, uses, or adaptations of the disclosure using its general principles. Further, this application is intended to cover such departures from the present disclosure as come within known or customary practice in the art to which this disclosure pertains and which fall within the limits of the appended claims.
This application is a continuation of U.S. patent application Ser. No. 14/996,637, filed Jan. 15, 2016, which claims priority to U.S. Provisional Application Ser. No. 62/104,130, filed Jan. 16, 2015, which is hereby incorporated by reference in its entirety.
