Description

31081 woSYSTEMS AND METHODS FOR TESTING IDENTIFICATION DEVICES FOR MEDICATION DELIVERY DEVICESTECHNICAL FIELD

[0001] The present disclosure relates to systems and methods for testing electronic identification devices for medication delivery devices, such as pen injectors and the like, and in particular to systems and methods for testing, validating, and / or recalibrating such identification devices.BACKGROUND

[0002] Patients suffering from various diseases must frequently inject themselves with medication. To allow a person to conveniently and accurately self-administer medicine, a variety of devices broadly known as pen injectors or injection pens have been developed. Generally, these pens are equipped with a cartridge including a piston and containing one or more doses of liquid medication. A drive member is movable forward to advance the piston in the cartridge to dispense the contained medication from an outlet at the distal cartridge end, typically through a needle. In disposable or prefilled pens, after a pen has been utilized to exhaust the supply of medication within the cartridge, a user discards the entire pen and begins using a new replacement pen. In reusable pens, after a pen has been utilized to exhaust the supply of medication within the cartridge, the pen is disassembled to allow replacement of the spent cartridge with a fresh cartridge, and then the pen is reassembled for its subsequent use.

[0003] Administration of the correct medication is important. A patient may need to select either a different medication, or a different form of a given medication, depending on the circumstances. If a mistake is made as to which medication is in a medication delivery device, then the patient will not be properly dosed, and records of dose administration will be inaccurate.

[0004] Accordingly, reusable devices have been developed that removably couple to medication delivery devices and facilitate automatically identifying information31081 wo about the type of medication contained therein and delivered to a patient. Some of these identification devices use one or more optical or light sensors to facilitate identifying indicative information about medication delivery devices and the type of medication contained therein. However, testing and validating the capabilities of these devices for optically identifying various types of medication delivery devices is onerous, and improvements are needed.SUMMARY

[0005] In one embodiment, a method for testing a first device used for detecting data from a second device or object is described with the following one or more steps. Providing a testing apparatus comprising a reflective display configured to generate a plurality of images, each of the images indicative of a feature of the second device or object. Positioning the first device on the testing apparatus. Displaying one of the plurality of images via the reflective display. Emitting visible light from the light source toward the reflective display while displaying the image via the reflective display. Receiving by a light sensor of the first device visible light reflected by the reflective display and affected by the image. Determining at least a first test value based on the visible light reflected by the reflective display and affected by the image. Comparing the first test value to at least a first expected value.

[0006] In another embodiment, a system for testing a first device used for detecting data from a second device or object is disclosed. The first device comprising a light source and a light sensor. The system including a testing apparatus and a processor. The testing apparatus is configured to mount the first device thereon. The testing apparatus includes a reflective display configured to generate a first image from a plurality of images. Each of the images is indicative of a feature of the second device or object. The reflective display is configured to reflect visible light emitted by the visible light source back to the first device when the first image is displayed. The first device is configured to determine at least a first test value based on the visible light reflected by the reflective display and affected by the first31081 wo image. The processor is configured to compare the first test value to at least a first expected value.

[0007] In another embodiment, a method for testing an identification device for a medication delivery device is disclosed. The identification device includes a visible light source and a visible light sensor. The method includes one or more of the following steps. Providing a testing apparatus including a reflective display configured to generate a plurality of color images. Each of the color images is indicative of a surface feature of the medication delivery device. Positioning the identification device on the testing apparatus. Conducting a first subtest by the following: displaying a first color image from the plurality of color images via the reflective display; emitting visible light from the visible light source toward the reflective display while displaying the first color image via the reflective display; receiving at the visible light sensor visible light reflected by the reflective display and affected by the first color image; determining at least a first test value based on the visible light reflected by the reflective display and affected by the first color image; and comparing the first test value to at least a first expected value. Conducting a second subtest by the following: displaying a second color image from the plurality of color images via the reflective display, the second color image being different than the first color image; emitting visible light from the visible light source toward the reflective display while displaying the second color image via the reflective display; receiving at the visible light sensor visible light reflected by the reflective display and affected by the second color image; determining at least a second test value based on the visible light reflected by the reflective display and affected by the second color image; and comparing the second test value to at least a second expected value.

[0008] In another embodiment, a system for testing an identification device used for detecting data from a medication delivery device is disclosed. The identification device includes a light source and a light sensor. A testing apparatus is configured to mount the identification device thereon. The testing apparatus includes a reflective display configured to generate a first color image from a plurality of color31081 wo images. Each of the color images is indicative of a surface feature of the medication delivery device. The reflective display is configured to reflect visible light emitted by the visible light source back to the identification device when displaying the first color image. The identification device is configured to determine at least a first test value based on the visible light reflected by the reflective display and affected by the first color image. A processor is configured to compare the first test value to at least a first expected value, and to indicate that the identification device passed a first subtest if the first test value differs from the first expected value by no more than a first threshold; or to indicate that the identification device failed the first subtest if the first test value differs from the first expected value by more than the first threshold.BRIEF DESCRIPTION OF THE DRAWINGS

A medication may be formulated with one or more excipients.

[0018] Illustratively, the first device 102 includes a generally cylindrical body 104 with a blind recess 106 for receiving, after manufacturing and during a testing procedure, a portion of the testing apparatus 100. During subsequent use, more specifically when the first device 102 and one or more medication delivery devices are used by a patient, the first device 102 may receive a portion of a medication delivery device in the recess 106 to facilitate identifying the medication delivery device and its medication. Generally, the first device 102 carries within the recess 106 one or more visible light sources 108 and one or more visible light sensors 110 to facilitate identifying a medication delivery device and its medication. These aspects are described in further detail below.

[0019] With continued reference to FIG. 1 , the testing apparatus 100 illustratively includes a base 112, an upwardly extending pedestal 114, and a reflective or non- emissive display 1 16 carried on the pedestal 1 14. During a testing procedure, the first device 102 is positioned downwardly on the testing apparatus 100 such that the reflective display 116 and the pedestal 1 14 are received in the recess 106 of the first device 102. The display 116 then displays one image or a sequence of images emulating the appearance of identification features of a second device or object, such as medication delivery devices with which the first device 102 may be used and which the first device 102 is configured to identify. As used herein, the term “identification feature(s)” means any detectable image feature from a medication delivery device that can be detected with a sensor by which data is generated that can be used to identify medication delivery device and / or medication within said device. Such identification features may include color, graphics, text, scannable codes (like QR codes), shapes, surface textures. The sensor can be an optical sensor, camera, or other sensor capable of detecting an identification feature. For example, the first device 102 may be configured to identify medication delivery devices and medications carried therein based on the color of one or more components of such devices. As another example, the first31081 wo device 102 may be configured to identify medication delivery devices and medications carried therein based on additional or alternative indicia provided on the medication delivery devices, such as QR codes, one or more shapes, including sets of concentric circles, and the like.

[0020] In some embodiments, the testing apparatus 100 may have different arrangements and / or orientations. For example, the testing apparatus 100 may be oriented such that the pedestal 1 14 extends horizontally from the base 1 12, and the first device 102 may be positioned horizontally on the testing apparatus 100. In various embodiments, the first device 102 may be fully supported by the testing apparatus 100, or the first device 102 may be supported on the testing apparatus 100 by other means. For example, an operator may hold the first device 102 on the testing apparatus 100.

[0021] FIG. 2 schematically illustrates the first device 102 and a remote computing device 118. The first device 102 is illustratively in communication with the remote computing device 1 18 via a communication unit 120 (for example, via a wired and / or wireless connection). The communication unit 120 can be, for example, a Wi-Fi transceiver, a Bluetooth transceiver, an RFID transceiver, a USB transceiver, a near-field communication (NFC) transceiver, a combination chip, and / or the like. After manufacturing and during a testing procedure, the remote computing device 118 may also be in communication with the testing apparatus 100 (shown elsewhere) and facilitate testing the first device 102 in the manners described herein. In such situations, the remote computing device 1 18 may be, for example, a desktop or laptop computing device. During subsequent use of the first device 102 by a patient, the remote computing device 1 18 may be a mobile computing device, such as a smartphone.

[0022] With continued reference to FIG. 2, the first device 102 illustratively further includes a processor 122 (for example, a microcontrol unit (MCU)) in communication with the communication unit 120. The processor 122 is also in communication with one or more sensors, more specifically the one or more visible light sensors 1 10, and a control unit or light source, such as a light emitting diode31081 wo(LED) driver 124. In some embodiments, the visible light sensor 1 10 is an ambient light sensor (ALS), for example, operating in a reflective mode. In some embodiments, the visible light sensor 1 10 is a color sensor including separate R, G, B sensors, a single package of RGB sensors, or a combination thereof, capable of detecting R, G, B values from the reflection of the light. The LED driver 124 is in communication with the one or more visible light sources 108, more specifically a set of LEDs 108A, 108B and 108C (collectively LEDs 108). The LEDs 108 may be a red (“R”) LED 108A, a blue (“B”) LED 108B, and / or a green (“G”) LED 108C. The light sensor 1 10 and / or the LEDs 108 may be in optical communication with external objects (for example, the display 1 16 of the testing apparatus 100 during a testing procedure, or a medication delivery device during subsequent use by a patient) via a light guide 126. The light guide 126 can be a transparent light guide, such as a Makrolon 2458 LightGuide. Other components, features, and / or aspects of the first device 102 may be the same or similar to those described in International Application Publication No. W02021 / 034902A2, the disclosure of which is hereby incorporated by reference in its entirety.

[0023] FIG. 3 schematically illustrates a testing system 128 including the testing apparatus 100 and a remote computing device 130. The testing apparatus 100 is illustratively in communication with the remote computing device 130 via a communication unit 132 (for example, via a wired and / or wireless connection of any of the specific types described hereinabove). The remote computing device 130 may be the same remote computing device 118 in communication with the first device 102 (both shown elsewhere). The testing apparatus 100 illustratively further includes a processor 134 (for example, an MCU)) in communication with the communication unit 132. The processor 134 is also in communication with a control unit or display driver 136, which is in turn in communication with the reflective display 1 16. The reflective display 116 is generally configured to generate a plurality of images and display such images to the first device 102. The reflective display 1 16 may specifically be, for example, an electronic paper display, more specifically an electrofluidic display, an interferometric modulator display, an31081 wo electrophoretic display, a reflective liquid crystal display (LCD), or the like. In other embodiments, one or more components may be disposed remotely from the testing apparatus 100, such as the processor 134, or the processor 134 could be a part of the remote computing device 1 18.

[0024] FIGS. 4 and 5 illustrate a flow diagram of a method 200 for testing a first device for a second device or object, such as a medication delivery device, according to an embodiment of the present disclosure. The following description of the method 200 refer to the testing system 128, the first device 102, and components thereof in an exemplary manner, and it is understood that the method 200 may be used in connection with other systems and devices contemplated herein. The method 200 begins at block 202 by providing the testing apparatus 100 including the reflective display 1 16. At block 204, the first device 102 is positioned on the testing apparatus 100. In some embodiments, the first device 102 is positioned on the testing apparatus 100 such that the reflective display 1 16 and the pedestal 114 of the testing apparatus 100 are received in the recess 106 of the first device 102. At block 206, the testing system 128 then conducts A / subtests for the first device 102, where N is the number of medication delivery devices the first device 102 is intended to identify. For example, N may be 1 , 2, 3, 4, 5, 6, 7, 8, 9, 10, or more.

[0025] Referring specifically to FIG. 5, at block 208 the nth subtest (for example, n = 1 , 2, ... N; the first subtest, the second subtest, and so forth through the A / th subtest) begins with the reflective display 1 16 displaying an nth image (for example, a first image, a second image, and so forth through an A / th image). In some embodiments, the nth image may be an nth color image (for example, a first color image, the second color image, and so forth through an A / th color image), with each color image being different than the others. More specifically, the nth color image may be an nth solid color, or single color, or monochromatic, image (for example, a first solid color image, a second solid color image, and so forth through an A / th solid color image). In some embodiments, the nth image may additionally or alternatively include identification features, such as QR codes, one31081 wo or more shapes, including sets of concentric circles, and the like. For example, in one embodiment of the test system and methods, the nth image may comprise a first nth image (such as color) that is different from the second nth image (such as graphic).

[0026] At block 210, the visible light source(s) 108 of the first device 102 then emit(s) light toward the reflective display 116 while the reflective display 116 displays the nth image (for example, a first image, the second image, and so forth through the A / th image). At block 212, the light sensor(s) 1 10 of the first device 102 receive(s) light reflected by the reflective display 116 and affected by the nth image (for example, the first image, the second image, and so forth through the A / th image). Each image affects the light from the first device 102 by reflecting light of certain wavelengths. To this end, the light reflected is a modified version of the light emitted and is modified by the image from the display. As examples, a red image reflects red light, having a wavelength of about 660nm, a green image reflects green light, having a wavelength of about 535nm, and blue image reflects blue light, having a wavelength about 475nm.

[0027] At block 214, one or more nth test values, or illumination values, (for example, a first test value, a second test value, and so forth through an A / th test value) are determined based on the light received by the sensor 1 10, more specifically the light reflected by the reflective display 1 16 and affected by the nth image (for example, the first image, the second image, and so forth through the A / th image). The nth test values may include, for example, numeric values for one or more of the RGB components of the reflected and affected light, one or more transformed or adjusted values based on one or more RGB component values, one or more normalized values based on one or more RGB component values, or the like. The nth test values may be determined by the processor 122 of the first device 102 and / or the remote computing device 1 18.

[0028] At block 216, the one or more nth test values (for example, the first test value, the second test value, and so forth through the A / th test value) are compared to one or more nth expected values (for example, a first expected value, a second31081 wo expected value, and so forth through an A / th expected value). The / 7th expected values may include, for example, numeric values for one or more of the RGB components, transformations thereof, or normalizations thereof similar to those described hereinabove. In embodiments in which medication delivery devices are identified via indicia, the nth test values may be compared to the / 7th expected values using any of various image matching methods, including pixel matching methods. The nth test values may be compared to the nth expected values by the remote computing device 1 18, the processor 122 of the first device 102, and / or the processor 134 of the testing apparatus 100. In certain embodiments, the expected values may be stored by the remote computing device 118, the first device 102, and / or the testing apparatus 100. In some embodiments, the expected values may be known based on previous experiments with first devices and second devices or objects, such as medication delivery devices.

[0029] In some embodiments, comparing the one or more nth test values (for example, the first test value, the second test value, and so forth through the A / th test value) to the one or more nth expected values (for example, the first expected value, the second expected value, and so forth through the A / th expected value) includes determining whether or not the nth values differ by more than an nth threshold (for example, a first threshold, a second threshold, and so forth through an A / th threshold). If the nth test and expected values (for example, the first test and expected values, the second test and expected values, and so forth through the A / th test and expected values) differ by no more than the nth threshold (for example, the first threshold, the second threshold, and so forth through the A / th threshold), the system 128 may indicate that the first device 102 passed, or is validated for, the nth subtest (for example, the first subtest, the second subtest, and so forth through the A / th subtest). Such an indication may include providing a visual or audible notification and / or retaining a record of passing the / 7th subtest (for example, the first subtest, the second subtest, and so forth through the A / th subtest) on the first device 102 and / or the testing system 128. Conversely, if the nth test and expected values (for example, the first test and expected values, the31081 wo second test and expected values, and so forth through the A / th test and expected values) differ by more than the nth threshold (for example, the first threshold, the second threshold, and so forth through the A / th threshold), the system 128 may indicate that the first device 102 failed the nth subtest (for example, the first subtest, the second subtest, and so forth through the A / th subtest). Such an indication may include providing a visual or audible notification and / or retaining a record of failing the nth subtest (for example, the first subtest, the second subtest, and so forth through the A / th subtest) on the first device 102 and / or the testing system 128. In certain embodiments, following failure of a subtest, the first device 102, particularly the visible light sensor 1 10, may be recalibrated. For example, the first device 102 may be instructed to adjust signals received from the visible light sensor 1 10 by an adjustment factor. In some embodiments, following failure of a subtest and recalibration of the first device 102, the subtest may be repeated. In addition, or instead of recalibration, the device can be ruled as defective.

[0030] The subtests continue through the A / th subtest, and the position of the first device 102 may be maintained on the testing apparatus 100 between each subtest, thereby providing a relatively fast testing method compared to having separate fixtures with a static image by which the first device would have to be tested and removed for each test fixture, added in a future state. The costs to create and maintain multiple test fixtures can be reduced with the test system and method disclosed herein which includes a single reflective or non-emissive display in which images can be changed for testing. Returning to FIG. 4, after all of the N subtests have been conducted, the method 200 concludes at block 218 by removing the first device 102 from the testing apparatus 100.

[0031] While this invention has been shown and described as having preferred embodiments, the present invention may be modified within the spirit and scope of this disclosure. This application is therefore intended to cover any variations, uses or adaptations of the invention 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 invention pertains.
