Description

FIELD

The present disclosure relates to an article, a system, and a method for indication of treatment.

BACKGROUND

Various medical devices are used in numerous procedures in the medical field. These devices are as varied as the procedures themselves. After a medical device, such as an endoscope, is used, the medical device is treated (e.g., cleaned, disinfected, and/or sterilized) in order to prepare the medical device for its next use. Ensuring the medical device is properly treated prior to the ultimate use on a patient can prevent the risk of cross contamination and the spread of disease.

DETAILED DESCRIPTION

Certain examples of the present disclosure will now be described to provide an overall understanding of the principles of the structure, function, manufacture, and use of the devices and methods disclosed herein. Various examples are illustrated in the accompanying drawings. Those of ordinary skill in the art will understand that the devices and methods specifically described herein and illustrated in the accompanying drawings are non-limiting examples and that the scope of the various examples of the present disclosure is defined solely by the claims.

Reference throughout the specification to “various examples,” “some examples,” “one example,” “an example,” or the like, means that a particular feature, structure, or characteristic described in connection with the example is included in at least one example. Thus, appearances of the phrases “in various examples,” “in some examples,” “in one example”, “in an example,” or the like, in places throughout the specification are not necessarily all referring to the same example. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one example or two or more examples. Thus, the particular features, structures, or characteristics illustrated or described in connection with one example may be combined, in whole or in part, with the features, structures, or characteristics of one other example or two or more examples without limitation. Such modifications and variations are intended to be included within the scope of the present disclosure.

In the present disclosure, unless otherwise indicated, all numerical parameters are to be understood as being prefaced and modified in all instances by the term “about,” in which the numerical parameters possess the inherent variability characteristic of the underlying measurement techniques used to determine the numerical value of the parameter. At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the scope of the claims, each numerical parameter described herein should at least be construed in light of the number of reported significant digits and by applying ordinary rounding techniques.

Also, any numerical range recited herein includes all sub-ranges subsumed within the recited range. For example, a range of “1 to 10” includes all sub-ranges between (and including) the recited minimum value of 1 and the recited maximum value of 10, that is, having a minimum value equal to or greater than 1 and a maximum value equal to or less than 10. Any maximum numerical limitation recited in this specification is intended to include all lower numerical limitations subsumed therein, and any minimum numerical limitation recited in this specification is intended to include all higher numerical limitations subsumed therein. Accordingly, Applicant reserves the right to amend this specification, including the claims, to expressly recite any sub-range subsumed within the ranges expressly recited. All such ranges are inherently described in this specification such that amending to expressly recite any such sub-ranges would comply with the requirements of 35 U.S.C. § 112 and 35 U.S.C. § 132(a).

The grammatical articles “a,” “an,” and “the,” as used herein, are intended to include “at least one” or “one or more,” unless otherwise indicated, even if “at least one” or “one or more” is expressly used in certain instances. Thus, the articles are used herein to refer to one or more than one (i.e., to “at least one”) of the grammatical objects of the article. Further, the use of a singular noun includes the plural, and the use of a plural noun includes the singular, unless the context of the usage requires otherwise.

A device such as a medical device (e.g., and endoscope) can undergo a treatment process to prevent cross-contamination and the spread of disease. As used herein, a “treatment process” may be a cleaning process, a disinfecting process, a sterilization process, the like, and combinations thereof. A treatment process may be either manual, automated, or some combination thereof, and may utilize a treatment agent. As used herein, a “treatment agent” can comprise at least one of a cleaning agent, a disinfectant, and a sterilant. As used herein a “cleaning process” means a treatment process employing a cleaning agent that removes and/or eliminates debris such as, for example, a dirt, a dust, a particle, an oil, a protein, a carbohydrate, and the like. As used herein, a “cleaning agent” means a type of treatment agent that removes and/or eliminates debris during a cleaning process such as, for example, a surfactant and/or a detergent.

A disinfecting process and a sterilization process can remove and/or eliminate a bioburden from a device. A bioburden may be, for example, a bacterium (e.g., mycobacterium, bacterial spores), an archaeon, a eukaryote, a virus, a fungus, and/or other forms of biological agents. Bacterial spores (e.g., endospores) are a form of bacteria which are dormant and highly resistive to physical and chemical degradation. As used herein, a “disinfecting process” means a treatment process that substantially removes a bioburden except for bacterial spores. As used herein, “substantially remove” means that at least 99% of the bioburden has been removed from the device such as, for example, at least 99.9% of the bioburden, at least 99.99% of the bioburden, at least 99.999% of the bioburden, or at least 99.9999% of the bioburden has been removed from the device. As used herein, a “sterilization process” means a treatment process which substantially removes a bioburden including bacterial spores. The sterilization process may include, for example, the addition of heat, freezing, a sterilant, irradiation, pressure, and combinations thereof. The sterilant may comprise a chemical capable of sterilization. The disinfection process may include, for example, the addition of heat, a disinfectant, irradiation, pressure, and combinations thereof. The disinfectant may comprise a chemical capable of disinfection.

Ensuring that a treatment process is properly performed on a device can support prevention of cross-contamination and the spread of disease. Testing a device, such as a medical device (e.g., an endoscope), directly may not be practical due to cost and/or time constraints. Thus, the present disclosure provides an article, a method, and a system for indication of treatment that can be employed to determine the effectiveness of a treatment process to which the device was subjected.

FIGS. 1A-B and 2A-B illustrate one example of an article 100 for indication of treatment according to the present disclosure. The article 100 can comprise a first body 102 and a second body 104. The first body 102 may comprise a cavity 108 positioned therein and configured to receive at least a portion of the second body 104. The cavity 108 may be any size and shape that allows for cooperative engagement with the second body 104. The first body 102 may cooperatively engage the second body 104 in a partially or fully sealed orientation. As illustrated, the first body 102 may be a sleeve-like I-shaped member, and the second body 104 may comprise a generally rectangular chamber 116 that can be received into the cavity 108 of the first body 102. An axis 106 extends through the first body 102 from a first end 102a to a second end 102b and illustrates one longitudinal orientation by which the second body 104 may engage the first body 102. The second end 102b can be oppositely disposed from the first end 102a.

The first body 102 can comprise at least two ports 110 and 112. Each port 110, 112 can be a bore through the first body 102. The ports 110 and 112 can be suitable to receive fluid and transport fluid therethrough. Port 112 can be offset from port 110 relative to axis 106, as illustrated. For example, port 112 can be more proximal to the second end 102b of the first body 102 than port 110. Port 112 can be adjacent to the second end 102b. Port 112 can also be radially offset from port 110 relative to axis 106.

The second body 104 can be positioned within the cavity 108 of the first body 102. The second body 104 can comprise an axis 114. The second body 104 can further comprise a chamber 116 configured to receive a fluid. Axis 114 can extend from a first end 104a of the second body 104 to a second end 104b of the second body 104. Axis 114 can be the same as axis 106. The second end 104b of the second body 104 can be oppositely disposed from the first end 104a. When the first body 102 and the second body 104 are engaged, the first end 102a of the first body 102 can be adjacent to the first end 104a of the second body 104 and the second end 102b of the first body 102 can be adjacent to the second end 104b of the second body 104.

The second body 104 can comprise at least two ports 118 and 120 that, for example, pair with ports 110, 112. Each port 118, 120 can be a bore through the second body 104. Port 118 and port 120 can be suitably configured to receive fluid and transport fluid therethrough. Port 120 can be offset from port 118 relative to axis 114, as illustrated. For example, port 120 can be more proximal to the second end 104b than port 118. Port 120 can be adjacent to the second end 104b. Port 102 can also be radially offset from port 118 relative to axis 114.

The ports 110, 112, 118, 120 can comprise any shape suitably configured to receive and transport fluid. For example, the ports 110, 112, 118, 120 can comprise at least one of a generally circular, a generally rectangular, and a generally oval cross-sectional shape.

A treatment indicator 122 can be positioned within the chamber 116 and can comprise biological material. For example, the biological material can comprise at least one of an archaeon, an eukaryote, a bacterium (e.g., bacterial spore), and a virus. The biological material degrades responsive to contact with at least one of a disinfectant and a sterilant. The level of degradation of the biological material in the treatment process can be dependent on, for example, at least one of the type of disinfectant and/or sterilant used, the contact time between the disinfectant and/or sterilant and the biological material, the temperature of the disinfectant and/or sterilant, and the activity of the disinfectant and/or sterilant.

The biological material can multiply (e.g., reproduce) responsive to contact with a growth media. The rate and/or amount of growth of the biological material can provide an indication of the effectiveness of a treatment process. For example, a sterilant can degrade the biological material on the treatment indicator 122 such that the treatment indicator 122 is substantially free from biological material. Therefore, upon contacting the treatment indicator 122 with growth media, minimal, if any, biological material can multiply resulting in a reduced rate and/or amount of growth of the biological material compared to a treatment indicator that was not degraded by a sterilant. The reduced rate and/or amount of growth can indicate, for example, whether the treatment process was effective or the degree to which the treatment process was effective.

The growth media (e.g., culture media) can comprise various materials to support the growth of biological material. For example, the growth media can comprise at least one of agar, water, a hormone, a growth factor, blood serum, a vitamin, glucose, glycerol, an ammonium salt, nitrate, and an amino acid. The growth media can be liquid.

The second body 104 can be moveable (e.g., slidable, rotatable, telescoping, etc.) relative to the first body 102, and/or the first body 102 can be moveable relative to the second body 104. For example, the article 100 can change position between a first configuration, as illustrated in FIG. 2A, and a second configuration, as illustrated in FIG. 2B. The configuration of the article 100 can enable or limit traversal of fluid into and/or out of the chamber 116 via, for example, the full or partial blockage of ports 110, 112, 118, 120. The fluid can comprise at least one of growth media, a rinse agent (e.g., water, alcohol), and a treatment agent (e.g., a cleaning agent, a disinfectant, a sterilant).

An offset distance from port 120 to port 118 relative to axis 114 can be the same as an offset distance from port 112 to port 110 relative to axis 106 so that there is a pairing between ports 110 and 118, and ports 112 and 120 when the second body 104 is received by first body 102. Movement of the first body 102 and/or second body 104 can control communication between port 110 and port 118 and between port 112 and port 120 simultaneously. For example, in the first configuration, port 110 can be aligned with port 118 to form a first fluid pathway 150 to the chamber 116, and port 112 can be aligned with port 120 to form a second fluid pathway 160 to the chamber 116. When aligned, fluid can flow into the chamber 116 utilizing ports 110, 112, 116, 118. For example, fluid can be introduced into port 110 and traverse through the first fluid pathway 150 into the chamber 116. Fluid can be introduced into port 112 and traverse through the second fluid pathway 160 into the chamber 116. While in the chamber 116, the fluid can contact the treatment indicator 122. In examples where the fluid comprises a disinfectant and/or sterilant, the fluid contact with the treatment indicator 122 can degrade biological material on the treatment indicator 122.

Fluid can flow out of the chamber 116 utilizing the first pathway 150 and/or second fluid pathway 160. For example, fluid can be introduced into port 118 from the chamber 116 and traverse through the first fluid pathway 150 out of the chamber 116. Fluid can be introduced into port 120 from the chamber 116 and traverse through the second fluid pathway 160 out of the chamber 116. The first configuration of the article 100 can be suitable to gravity drain fluid from the chamber 116. For example, the article 100 can be oriented such that fluid in the chamber 116 flows into port 120 and traverses through the second fluid pathway 160 out of the chamber 116. The first fluid pathway 150 can be configured as an inlet, and the second fluid pathway 160 can be configured as an outlet. Also, for example, the second fluid pathway 160 can be configured as an inlet, and the first fluid pathway 150 can be configured as an outlet.

The second configuration of the article 100 can inhibit and/or prevent communication between port 110 and port 118 and between port 112 and port 120. For example, in the second configuration, port 110 can be misaligned with port 118 and port 112 can be misaligned with port 120. The misalignment can inhibit or prevent traversal of fluid through the first fluid pathway 150 and/or second fluid pathway 160 via, for example, the full or partial blockage of ports 110, 112, 118, 120. In the second configuration, fluid remaining within the chamber 116 may be inhibited or prevented from exiting the chamber 116. For example, in the second configuration, the chamber 116 may be a closed system. Growth media can be in the chamber 116 while the article 100 is in the second configuration, and the growth media can contact the treatment indicator 122.

The article 100 can change configuration by a variety of methods. For example, article 110 can be configured to rotate at least one of the first body 102 around axis 106 and the second body 104 around 114 to change between the first configuration and the second configuration. The article 100 can be configured to translate at least one of the first body 102 relative to axis 106, and the second body 104 relative to axis 114 to change between the first configuration and the second configuration.

The configuration change of the article 100 can be manual (e.g., activated by an operator) or automatic. For example, the apparatus for treatment can automatically change the configuration of the article 100 responsive to at least a portion of a treatment process.

The article 100 can comprise additional components configured for facilitating the configuration change of the article 100. For example, the article 100 can comprise at least one of a spring and a piston. For example where the article 100 comprises a spring, the spring can be positioned between the first body 102 and the second body 104 in order to apply a force to translate at least one of the first body 102 relative to axis 106 and the second body 104 relative to axis 114. Similarly, the spring can be positioned in communication with the first body 102 and/or the second body 104 in order to apply a force to the first body 102 and/or second body 104 to rotate at least one of the first body 102 around axis 106 and the second body 104 around axis 114.

The treatment indicator 122 and/or fluid with the chamber 116 can comprise an electromagnetic property. The electromagnetic property can be, for example, at least one of absorption, transmittance, scattering, reflectance, and photoluminescence. The electromagnetic property can be measured in order to determine the rate and/or amount of biological material on the treatment indicator 122. For example, electromagnetic radiation can be emitted into the chamber 116, and electromagnetic radiation can be detected from the chamber 116. Based on the emitted and/or detected electromagnetic radiation, the electromagnetic property can be determined. The electromagnetic property can correspond to a rate and/or amount of biological material on the treatment indicator 122, and thus the measured electromagnetic property can be used to determine, for example, the rate and/or amount of biological material on the treatment indicator 122, whether the treatment process is complete, and the effectiveness of a treatment process. If the electromagnetic property is below a threshold value, the treatment process can be determined to be effective. If the electromagnetic property is at least the threshold value, the treatment process can be determined to be ineffective. A degree of effectiveness of the treatment process can be determined based on the measured electromagnetic property. If the treatment process is determined to be ineffective based on the measurement of the electromagnetic property, the treatment process may be discontinued, or the treatment process may continue with another treatment indicator until it is later determined that the treatment process is effective, based on a subsequent reading that the electromagnetic property is below a threshold value.

In order to facilitate a measurement of the electromagnetic property, the first body 102 can comprise an opening 140 and the second body 104 can comprise a corresponding transparent section 104c. For example, the opening 140 can be the void space created between the horizontal top/bottom and vertical middle portion of the “I” when the first body 102 is an I-shaped member, as illustrated. The transparent section 104c can be configured to allow transmission of electromagnetic radiation into and/or through the chamber 116. For example, the transparent section 104c can comprise a material that minimally absorbs, or does not absorb, electromagnetic radiation that is emitted through the chamber 116. The opening 140 can be configured to align with the transparent section 104c of the second body 104 when the article 100 is in a second configuration as illustrated in FIG. 2B. The first body 102 may be configured with a second transparent section (not shown) in place of the opening 140 and the second transparent section can be configured to transmit electromagnetic radiation into the transparent section 104c through the chamber 116. The transmission of electromagnetic radiation into and/or through the chamber 116 can enable measurement of an electromagnetic property of the treatment indicator 122 and/or fluid within the chamber 116.

FIGS. 3A-C and 4A-B illustrate another example of an article 300 for indication of treatment according to the present disclosure is provided. The article 300 comprises a first body 302 and a second body 304. The first body 302 may comprise a cavity 308 positioned therein and configured to receive at least a portion of the second body 304. The cavity 308 may be any size and shape that allows for cooperative engagement with the second body 304. The first body 302 may cooperatively engage the second body 304 in a partially or fully sealed orientation. As illustrated, the first body 302 may be a sleeve-like generally cylindrical-shaped member, and the second body 304 may comprise a generally cylindrical-shaped chamber 316 that can be received into the cavity 308 of the first body 302. Axis 306 extends through the first body 302 from a first end 302a to a second end 302b and illustrates one longitudinal orientation by which the second body 304 may engage the first body 302. The second end 302b can be oppositely disposed from the first end 302a.

The first body 302 can comprise at least four ports 310, 312, 324, and 326. The ports 310, 312, 324, 326 can be suitably configured to receive fluid and transport fluid. Port 312 can be offset from port 310 relative to axis 306. Port 324 can be offset from port 326 relative to axis 306. Port 310 can be positioned relative to axis 306 at the same position as port 324 or offset from port 324 relative to axis 306. Port 312 can be positioned relative to axis 306 at the same position as port 326 or offset from port 324 relative to axis 306.

The second body 304 can comprise an axis 314. Axis 314 can extend from a first end 304a of the second body 304 to a second end 304b of the second body 304. The second end 304b can be oppositely disposed from the first end 304a. The second body can further comprise a chamber 316 configured to receive a fluid.

The second body 304 can comprise at least four ports 318, 320, 328, and port 330 that, for example, pair with ports 310, 312, 324, 326, respectively. The ports 318, 320, 328, 330 can be suitably configured to receive fluid and transport fluid. Port 320 can be offset from port 318 relative to axis 314. Port 328 can be offset from port 330 relative to axis 314. Port 318 can be positioned relative to axis 314 at the same position as port 328 or offset from port 328 relative to axis 314. Port 320 can be positioned relative to axis 314 at the same position as port 330 or offset from port 330 relative to axis 314. A distance port 320 is offset from port 318 relative to axis 314 can be the same as a distance port 312 is offset from port 310 relative to axis 306 so that there is a pairing between ports 310 and 318, and ports 312 and 320 when the second body 304 is received by first body 302. A distance port 330 is offset from port 328 relative to axis 314 can be the same as a distance port 326 is offset from port 324 relative to axis 306 so that there is a pairing between ports 324 and 328, and ports 326 and 330 when the second body 304 is received by first body 302.

The treatment indicator 122 can be positioned within the chamber 316. The second body 304 can comprise a shape configured to be received by the cavity 308 of the first body 302. For example, the second body 304 can be positioned within the cavity 308 of the first body 302. The second body 304 can be moveable with respect to the first body 302 and/or the first body 302 can be moveable with respect to the second body 304. For example, as illustrated in FIG. 4A, the article 300 can be configured in a first configuration. In the first configuration, port 310 can be aligned with port 318 to form a first fluid pathway 350 to the chamber 316; port 312 can be aligned with port 320 to form a second fluid pathway 360 to the chamber 316; port 324 can be aligned with port 328 to form a third fluid pathway 370 to the chamber 316; and port 326 can be aligned with port 330 to form a fourth fluid pathway 380 to the chamber 316.

The article 300 can be configured to move between the first configuration in FIG. 4A and a second configuration as illustrated in FIG. 4B. In the second configuration, port 310 can be misaligned with port 318; port 312 can be misaligned with port 320; port 324 can be misaligned with port 328; and port 326 can be misaligned with port 330. The misalignment can inhibit or prevent traversal of fluid through at least one of the first fluid pathway 350, the second fluid pathway 360, the third fluid pathway 370, and the fourth fluid pathway 380 via, for example, the full or partial blockage of ports 310, 312, 318, 320, 324, 326, 328, 330. For example, in the second configuration of the article 300, the chamber 316 can be a closed system and fluid within the chamber 316 can be inhibited or prevented from exiting the chamber 316.

The article 300 can comprise a reservoir 332 configured to retain growth media. The reservoir 332 can be positioned within the chamber 316, and the reservoir 332 can comprise a seal 334 configured to retain growth media separate from the treatment indicator 122. The seal 334 can comprise at least one of a film, a membrane, a wall, and a vial. The seal 334 can comprise various materials, such as, for example, metallic materials, polymeric materials (e.g., plastic), ceramic materials, and glass materials.

The reservoir 332 can be configured to introduce the growth media to the treatment indicator 122 upon degradation of the seal 334. For example, in the first configuration of the article 300 (FIG. 4A), the seal 334 of the reservoir 332 may be configured to retain the growth media. In the second configuration of the article 300 (FIG. 4B), the seal 334 of the reservoir 332 can be configured to break and to introduce the growth media to the treatment indicator 122. For example, the seal 334 can be pierced, punctured, snapped, and/or torn.

As illustrated in FIGS. 4A-B, the reservoir 332 can be integral to the second body 304 and the article 300 can comprise a seal disruption member 336 comprising a first end 336a and a second end 336b. The first end 336 can be any shape or configuration that assists in breaking the seal 334, such as, for example, one or more fork tangs, as illustrated, to pierce the seal 334 in one or more locations. In the first configuration of the article 300, the seal 334 can be positioned a distance, d₁, from the second end 336b of the seal disruption member 336. When changing the article 300 from the first configuration to the second configuration, the first end 336a of the seal disruption member 336 can engage the second end 304b of the second body 304 and prevent movement of the seal disruption member 336 relative to axis 314 towards the second end 304b of the second body 304. During the configuration change of the article 300 from the first configuration to the second configuration, the distance between the seal 334 and the second end 304b of the body 304 can decrease, thereby allowing the first end 336a of the seal disruption member 336 to break the seal 334 and release growth media from the reservoir 332. The growth media can traverse into the chamber 316 and be introduced to and contact the treatment indicator 122. In the second configuration of the article 300, the seal 334 can be positioned a distance, d₂, from the second end 336b of the seal disruption member 336.

The reservoir 332 may not be integral to the second body 304 and may be a separate entity within the chamber 316. For example, the reservoir 332 may be a third body positioned within the chamber 316. The seal 334 can be a wall of the reservoir 332, which can be broken by changing the article 300 from the first configuration to the second configuration and/or another physical force. For example, seal 334 can be deformed causing the seal 334 to break and release the growth media into the chamber 316. The reservoir 332 can comprise a seal 334 of a glass vial, and deformation of the glass vial breaks the glass vial and releases the growth media into the chamber 316.

The reservoir 332 may be positioned outside of the article 300 and in communication with at least one of the ports, 310, 312, 324, 326. The growth media can be released from the reservoir 332 into the chamber 316 while the article 300 is in the first configuration, and then the article 300 can be positioned in the second configuration. It is contemplated that growth media can be injected into the chamber 316 with an injection device, such as, for example, a syringe.

The article 300 can comprise a keyway 338 positioned on an end of the second body 304, such as, for example, the second end 304b. The keyway 338 can be configured to facilitate alignment of the article 300 with an apparatus for treatment and/or a detector.

In order to facilitate a measurement of the electromagnetic property, the first body 302 can comprise an opening 340 and the second body 304 can comprise a corresponding transparent section 304c. The transparent section 304c can be configured to allow transmission of electromagnetic radiation into and/or through the chamber 316. For example, the transparent section 304c can comprise a material that minimally absorbs, or does not absorb, electromagnetic radiation that is emitted through the chamber 316. The opening 340 can be configured to align with the transparent section 304c of the second body 304 when the article 300 is in a second configuration as illustrated in FIG. 4B. The first body 302 may be configured with a second transparent section (not shown) in place of the opening 340 and the second transparent section can be configured to transmit electromagnetic radiation into the transparent section 304c through the chamber 316. The transmission of electromagnetic radiation into and/or through the chamber 316 can enable measurement of an electromagnetic property of the treatment indicator 122 within the chamber 316 and/or fluid within the chamber 316.

As illustrated in FIG. 5, the article 300 for indication of treatment can be introduced to a detector 542. The detector 542 can be configured to measure an electromagnetic property of fluid within the chamber 316 via the transparent section 304c of the second body 304. The detector 542 can comprise an electromagnetic radiation source 542a suitable to emit electromagnetic radiation 544a into the chamber 316 and an electromagnetic radiation detector 542b suitable to receive and measure electromagnetic radiation 544b. The electromagnetic radiation 544a emitted by the electromagnetic radiation source 542a can comprise a wavelength in a wavelength range of 100 nm to 1000 nm, and the electromagnetic radiation 544b received and measured by the electromagnetic radiation detector 542b can comprise a wavelength in a wavelength range of 100 nm to 1000 nm.

In examples where the electromagnetic property of the fluid comprises fluorescence, the electromagnetic radiation 544a can enter the chamber 316 and interact with the fluid within the chamber 316. The interaction can produce fluorescence as electromagnetic radiation 544b, which can be measured by electromagnetic radiation detector 542b. In examples where the electromagnetic property of the fluid comprises absorbance, the electromagnetic radiation 544a can enter the chamber 316, and at least part of the electromagnetic radiation 544a can be absorbed by the fluid within the chamber 316. The remaining portion of electromagnetic radiation 544b can leave the chamber 316 as electromagnetic radiation 544b, which can be measured by electromagnetic radiation detector 542b.

FIG. 6 illustrates a system 600 comprising an apparatus 646 for treatment and the article 300 for indication of treatment. As illustrated, the apparatus 646 can comprise a chamber 648 including a treatment basin 650 in fluid communication with a reservoir 656.

The chamber 648 can be suitably configured to perform a treatment process on the device 652 in the treatment basin 650. The chamber 648 can comprise at least one of a heater (e.g., heating element), a pump, a wash arm, a spray nozzle, a tube, and other features known to one of ordinary skill in the art. The chamber 648 can be at least one of a cleaning chamber, a disinfection chamber, and a sterilization chamber. The device 652 can be, for example, a medical device such as, for example, an endoscope. The apparatus 646 can comprise an endoscope re-processor (e.g., an automated endoscope re-processor).

The chamber 648 can comprise a vessel 654 positioned separate from the treatment basin 650. The vessel 654 can be in fluid communication with at least one of the treatment basin 650 and the reservoir 656. The vessel 654 can comprise a cavity suitable to receive the article 300 for indication of treatment. The vessel 654 can be configured to provide a fluid to the article 300, such as, for example, growth media, a rinse agent, and a treatment agent. The vessel 654 can subject the article 300 to the same treatment process that the device 652 is subjected to in the basin 650 such that the article 300 can accurately represent the degree to which the device 652 is treated.

The present disclosure provides a method for indication of treatment.
