[0105] The UV light 121 can include any wavelength spectrum suitable for disinfecting a surface. For example, the UV light can include a UV-C wavelength spectrum range from 100 nm to 280 nm. In some embodiments, the UV light 121 can include a far UV-C spectrum range from 207 nm to 225 nm.

[0106] In the illustrated embodiment, the device 110 includes a button 116 disposed on the device body 111, and in some embodiments, the logic can be configured to activate the UV light source 120 in response to pressing the button 116.

[0107] In some embodiments, the device 110 can include a proximity sensor 117 configured to determine the distance between the projection surface 123 and a skin surface 50. The logic can manage the activation and / or deactivation of the UV light source 120 based on the distance between the projection surface 123 and the skin surface 50 determined by the proximity sensor 117. For example, the logic can prevent the activation of the UV light source 120 unless the projection surface 123 is positioned within a predefined distance from the skin surface 50. Similarly, when the projection surface 123 moves away from the skin surface 50 such that the distance between the projection surface 123 and the skin surface 50 is greater than the predefined distance, the logic can automatically deactivate the UV light source 120. In some embodiments, the logic can deactivate the UV light source 120 after a predefined duration of UV light activation to prevent overexposure to the UV light 121.

[0108] The device 110 can be a stand-alone unit, or the device 110 can be combined, for example, with another medical device or apparatus, such as an ultrasound probe, a remote controller of another medical device / system, or an armband configured to attach / adhere the device 110 to a clinician.

[0109] According to some embodiments, the device 110 may include a UV shield 130 coupled to or incorporated into the device body 111.

[0110] The UV shield 130 may be configured to contact the skin surface 50 at the open end 131. In the illustrated embodiment, the length 133 of the UV shield may define a minimum distance between the skin surface 50 and the projection surface 123, where the minimum distance may limit the intensity of the UV light 121 projected onto the skin surface 50. In some embodiments, the device 110 may further include a contact sensor 118 coupled to the console 115, where the contact sensor 118 is configured to detect physical contact between the open end 131 of the UV shield 130 and the skin surface 50. In such an embodiment, the logic may prevent activation of the UV light source 120 in the absence of physical contact. Similarly, in some embodiments, the logic may activate the UV light source 120 in response to physical contact (i.e., when the contact sensor 118 detects physical contact).

[0127] Figure 3AFIG. 300 shows a medical disinfection system (the "System") 300 according to some embodiments. The System 300 is generally configured to disinfect the exterior of a person (such as a medical technician) before the person enters a controlled medical environment (e.g., an operating room). The System 300 includes an enclosure 310 configured to receive a person 50 therein and a plurality (e.g., 1, 2, 5, 10 or more) ultraviolet (UV) light sources 320 coupled to the enclosure 310, where the UV light sources 320 are configured to project UV light 321 onto an exterior 51 of the person 50 to disinfect the exterior 51 of the person. The enclosure 310 includes a peripheral wall 311 that defines the perimeter of the enclosure 310. The enclosure 310 may include any suitable shape configured to enclose the person 50 therein. For example, the enclosure 310 may include a rectangular shape having six sides (i.e., four vertical sides, a top, and a bottom).

[0128] In some embodiments, the peripheral wall 311 may be configured to contain the UV light 321 within the enclosure 310, i.e., the peripheral wall 311 may prevent the UV light 321 from being exposed to objects disposed outside the enclosure 310. In some embodiments, the peripheral wall 311 may be formed of a material that is transparent to visible light. The enclosure 310 may include an opening (not shown), such as a doorway, to enable entry into and exit from the enclosure 310. In some embodiments, the enclosure 310 may include a temporary structure configured for temporary setup and use within a medical environment, where the medical environment may include, for example, any environment in which a medical procedure may occur, such as a hospital, a clinic, or an emergency medical environment (e.g., a military medical tent).

[0129] The UV light sources 320 may be dispersed across the interior of the enclosure 310 in any suitable manner such that the UV light 321 is projected radially inwardly onto the exterior 51 of the person. In some embodiments, the UV light sources 320 may be dispersed across substantially the entire peripheral wall 311 such that when the person 50 stands within the enclosure 310, the person 50 is bathed in the UV light 321 (i.e., substantially the entire exterior 51 of the person is exposed to the UV light 321). In other embodiments, the UV light sources 320 may be coupled to the peripheral wall 311 such that the UV light 321 is projected onto the exterior 51 of the person in one or more discrete directions. In such embodiments, the person 50 may rotate (i.e., turn) so that the UV light 321 can be projected onto substantially the entire exterior 51 of the person. As an example, the UV light sources 320 may be arranged in a vertical linear array along opposite vertical sides of the peripheral wall 311. In such embodiments, the person 50 may rotate 180 degrees so that the UV light 321 can be projected onto substantially the entire exterior 51 of the person.

The logic may be configured to record disinfection events, where parameters of the disinfection events may include one or more of the following: the date of the disinfection event, the time of the disinfection event, or the activation duration of UV light source 320.

[0131] In some embodiments, system 300 may further include a UV light detection system 340 configured to detect exposure of UV light 321 on an exterior of a person 50, e.g., determine when the exterior of the person 50 is exposed to UV light 321.

[0132] In some embodiments, UV light detection system 340 may include a first UV light detector 341 (or a plurality of first UV light detectors 341) physically coupled to enclosure 310. First UV light detector 341 may be configured to detect UV light emitted (e.g., reflected) from the exterior of the person 51, and in some embodiments, first UV light detector 341 may be configured to determine the intensity of the UV light emitted from the exterior of the person 51, where the UV light emitted from the exterior of the person 51 may be related to the UV light 321 projected onto the exterior of the person 51. In some embodiments, first UV light detector 341 may be configured to scan the exterior of the person 51 to determine if substantially the entire exterior of the person 51 is exposed to UV light 321. For example, first UV light detector 341 may detect if any portion of the exterior of the person 51 is not exposed to UV light 321. In some embodiments, first light detector 341 may be communicatively coupled to console 315.

[0133] In some embodiments, as an alternative to or in addition to the first UV light detector 341, the UV light detection system 340 may include a second UV light detector 342, wherein the second light detector 342 is configured to be attached to the exterior of a person 51. The second UV light detector 342 is configured to detect UV light 321 received by the exterior of the person 51. In some embodiments, the UV light detection system 340 may include a plurality of second UV light detectors 342. In some embodiments, the second light detector 342 may be communicatively coupled to the console 315. Logic may be configured to determine a profile of UV light exposure on the exterior of the person 51. The profile of UV light exposure may include a coverage assessment of the UV light exposure. In other words, the logic receives signals or data from the first UV light detector 341 and / or the second UV light detector 342 and thereby determines which portions of the exterior of the person 51 have been exposed to UV light 321 and / or which portions of the exterior of the person 51 have not been exposed to UV light 321.

[0134] Figure 3B A second embodiment of the system 300 is shown and further includes a frame 312 disposed within the enclosure 310. In the illustrated embodiment, the frame 312 defines an inverted U-shape sized to receive a person 50 therein. The UV light source 320 is attached to the frame 312 such that the UV light source 320 projects UV light 321 radially inwardly to expose the exterior of the person 51 to the UV light 321 when the person 50 is positioned within the frame 312. In some embodiments, the UV light source 320 may be attached to the frame 312 such that the UV light source 320 forms a linear array along the frame 312, thereby defining a plane of the UV light 321. The frame 312 is coupled to the enclosure 310 such that the frame 312 is capable of rotating about a vertical axis 312A. In some embodiments, the vertical axis 312A may be centrally located within the enclosure 310. Thus, during operation, the frame 312 rotates about the person 50 such that the UV light source 320 travels along a circular path around the person 50, thereby projecting the UV light 321 onto a 360-degree circumference of the exterior of the person 51. A rotation actuator 313 may be coupled between the frame 312 and the enclosure 310, and the rotation actuator 313 may be operatively coupled to the console 315 such that the logic may manage the operation of the rotation actuator 313.

The objects may include, for example, any surface within the patient transport vehicle 60, such as a seat, a handle, or medical equipment. Other exemplary objects may include tools, instruments, or other medical materials, such as drapes, gloves, gowns, or other materials where lack of disinfection may pose a risk to a patient. The patient transport vehicle 60 may include, for example, any suitable vehicle for transporting a patient, such as an ambulance or a helicopter. When the UV light source 420 projects and / or disperses the UV light 421 within the patient transport vehicle 60, the patient transport vehicle 60 may be configured to contain the UV light 421 within the patient transport vehicle 60. Thus, a window 66 of the patient transport vehicle 60 may be configured to inhibit UV light transmission therethrough. Or more specifically, the window 66 may be configured to prevent the UV light 421 from transmitting through the window 66 from the interior of the window 66 to the exterior of the window.

[0140] The UV light source 420 can be configured to be attached to the inner surface of the patient transport vehicle 60, and the UV light source 420 can be configured to project UV light 421 inwardly away from the inner surface to expose an object to the UV light 421. In some embodiments, the UV light system 419 can include one or more reflective surfaces 422 configured to reflect the UV light 421 and thereby enhance the exposure of the object to the UV light 421. When the patient and other medical personnel may occupy the patient transport vehicle 60, the UV light system 419 can be configured to activate the UV light source during non-operating periods of the patient transport vehicle 60. For example, the system 400 can be configured to disinfect the patient transport vehicle 60 between patient transport events.

[0141] The UV light system 419 can be configured for selective placement in different regions or compartments of the patient transport vehicle 60, i.e., the UV light system 419 can be movable. Similarly, the UV light system 419 can be configured for selective placement in different patient transport vehicles 60 as needed. In the illustrated embodiment, the UV light system 419 can be capable of moving between at least a first compartment and a second compartment of the patient transport vehicle 60. In some embodiments, the first compartment can include a medical personnel compartment 62 (i.e., the cab of the vehicle), and the UV light system 419 is configured to disinfect objects within the medical personnel compartment 66. In some embodiments, the UV light system 419 can be configured to deactivate the UV light source 420 when there is an occupant within the medical personnel compartment 66 to prevent the occupant from being exposed to the UV light 421. In some embodiments, the second compartment can include a patient compartment 63, and the UV light system 419 can be configured to disinfect objects within the patient compartment 63. In some embodiments, the UV light source 420 can be coupled to the overhead ceiling surface 63A of the patient compartment 63.

[0142] In some embodiments, the UV light system 419 can include a remote control 414 configured to enable a user of the system 400 to remotely activate and deactivate the UV light source 420. In some embodiments, the UV light system 419 can include a timer 415 operatively coupled to the UV light source 420, where the timer 415 can be configured to at least deactivate the UV light source 420 after a defined activation period.

The UV light system 419 can be electrically coupled to the electrical system 67 of the patient transport vehicle 60. In some embodiments, instead of or in addition to being coupled to the electrical system 67, the UV light system 419 can include a battery (not shown).

[0143] Figures 5A to 5EShows various embodiments of a medical disinfection system configured to disinfect various high-frequency touch surfaces of a patient care facility. The high-frequency touch surfaces can include any surface within the patient care facility. In some implementations, the high-frequency touch surfaces can be located, for example, within a patient care environment (such as an operating room). In other implementations, the high-frequency touch surfaces can be located, for example, within a sterile controlled environment (such as an intravenous preparation environment in a pharmacy). Various medical disinfection systems are configured to disinfect the high-frequency touch surfaces by exposing the high-frequency touch surfaces to ultraviolet light.

Figure 5B Is taken along section line 5B-5B Figure 5A Cross-sectional view of the handle 551 of. Refer to Figure 5A And Figure 5B , the medical disinfection system 501 includes a UV light system 519, the UV light system being configured to project UV light 521 from the inside of the handle 551 outward through the transparent material of the handle 551. More specifically, the high-frequency touch surface 551A is the outer surface of the handle 551, where the handle 551 includes a material (or is formed of) that is transparent to UV light 521. The UV light system 519 includes a plurality (e.g., 1, 2, 3, or more) of UV light sources 520, the plurality of UV light sources (e.g., within a cavity 551B) being arranged below the outer surface of the handle 561 such that the UV light 521 travels through the transparent material to the high-frequency touch surface 551A. Thus, the UV light source 520 is optically coupled to the high-frequency touch surface 551A. In some embodiments, the handle 551 can include a latch.

[0145] Figure 5CA perspective view of a medical disinfection system 502 configured to expose a handle portion 561 with a high-frequency touch surface 561A is shown. In the illustrated embodiment, the handle portion 561 defines an elongated shape, and the elongated shape defines the length of the handle portion 561. Similar to the medical disinfection system 501, the medical disinfection system 502 includes a UV light system 519 configured to project UV light 521 from the interior of the handle portion 561 outwardly through the transparent material of the handle portion 561. The UV light system 519 includes a plurality (e.g., 1, 2, 3, or more) of UV light sources 520 disposed within a cavity 561B of the handle portion 561. The UV light sources 520 may also include one optical fiber 563 or a plurality (e.g., 1, 2, 3, or more) of optical fibers 563. In some embodiments, the optical fiber 563 is configured to project the UV light 521 laterally (e.g., radially) away from the optical fiber 563 along the length of the optical fiber 563. The optical fiber 563 extends along the length of the handle portion 561 such that the optical fiber 563 projects the UV light 521 radially outward from the optical fiber 563 along the length of the handle portion 561, thereby disinfecting the high-frequency touch surface 561A along substantially the entire length of the handle portion 561.

[0146] Figure 5D A perspective view of a medical disinfection system 503 configured to expose a handle portion 571 (e.g., a doorknob as shown) with a high-frequency touch surface 571A is shown. The UV light system 519 includes one UV light source 520 or a plurality (e.g., 1, 2, 3, or more) of UV light sources 520 disposed away from the handle portion 571. The UV light source 521 is configured to project the UV light 521 onto the high-frequency touch surface 571A from a distance away from the high-frequency touch surface 571A. For example, the UV light source 520 may be attached to a ceiling surface. The UV light source 520 is configured to focus the UV light 521 onto the high-frequency touch surface 571A such that only the area 521A adjacent to the high-frequency touch surface 571A and the surface adjacent to the high-frequency touch surface 571A are exposed to the UV light 521. By focusing the UV light 521, objects or materials that may be damaged due to exposure to the UV light 521 are spared from exposure to the UV light 521.

[0147] Figure 5EA side view of a medical disinfection system 503 is shown that is configured to expose a high-frequency touch surface 581A of a handle 581 (e.g., a doorknob as shown). The UV light system 519 includes one UV light source 520 or multiple (e.g., 1, 2, 3, or more) UV light sources 520 that are configured to expose the high-frequency touch surface 581A to UV light 521. The medical disinfection system 504 includes a shield 583 that is configured to at least partially cover or encapsulate the high-frequency touch surface 581A. The UV light source 521 is attached to the lower (or inner) surface of the shield 583, and the UV light source 521 is configured to project the UV light 521 away from the inner surface of the shield 583 to the high-frequency touch surface 581A. In some embodiments, the inner surface includes a reflective surface that is configured to enhance the exposure of the high-frequency touch surface 581A to the UV light 521.

In the deployed position 583A, the shield 583 can substantially cover (or encapsulate) the high-frequency touch surface 581A such that the UV light source 521 can effectively expose substantially the entire high-frequency touch surface 581A to the UV light 521. In contrast, in the retracted position 583B, the shield 583 can substantially expose the high-frequency touch surface 581A, i.e., the shield 583 can be arranged far enough away from the high-frequency touch surface 581A to allow a user to access the handle 581.

[0149] Figures 6A to 6C Various embodiments of a medical disinfection system configured to disinfect a continuous positive airway pressure (CPAP) system 650 are shown. More specifically, the medical disinfection system is configured to disinfect the interior 655A (i.e., the inner surface) of the tubing 655 of the CPAP system 650. According to some embodiments, the medical disinfection system includes an ultraviolet (UV) light system 619 that is configured to disinfect the interior 655A of the tubing 655 by exposing the interior 655A to UV light 621. The material of the tubing 655 can be compatible with exposure to the UV light 621. In other words, the tubing 655 can generally be configured to withstand UV light exposure without damage or degradation.

[0150] Figure 6AA medical disinfection system 601 is shown, which includes a CPAP system 650. The CPAP system includes a CPAP module 654 operatively coupled to a pipe member 655. During use of the UV light system 619, the UV light system 619 is coupled to the CPAP system 650. The UV light system 619 includes an elongate member 630 having one UV light source 620 or multiple (1, 2, 3, or more) UV light sources 620 coupled thereto. During use, the elongate member 630 including the UV light source 620 is inserted into the pipe member 655 such that the UV light source 620 can project UV light 621 onto the interior 655A, that is, expose the interior 655A to the UV light 621. In some embodiments, the UV light source 620 may be located at the free end 631 of the elongate member 630. The elongate member 630 may include a stylet, a detector, an endoscope, or any other suitable elongate device configured to be placed within the pipe member 655. The UV light system 619 may receive power from a facility power supply, or the UV light system 619 may be battery-powered, that is, include a battery (not shown).

[0151] The UV light source 620 (including the elongate member 630) is configured to be selectively inserted into and removed from the pipe member 655. In some embodiments, the user may insert the UV light source 620 into the pipe member 655 between CPAP events to disinfect the pipe member 655. In some embodiments, the UV light source 620 includes a single light source 620 at the free end 631. In such embodiments, during advancement or retraction of the UV light source 620 along the length of the pipe member 655, the UV light source 620 may disinfect segments or portions of the interior 655A. In other embodiments, the UV light source 620 includes multiple UV light sources 620 arranged along the length of the elongate member 630. In such other embodiments, after the elongate member 630 is placed within the pipe member 655, that is, when the elongate member 630 resides within the pipe member 655, the UV light sources 620 may disinfect the interior 655A.

[0152] In some embodiments, the UV light system 619 may include a notification system 617 configured to indicate the status of the disinfection cycle of the UV light system 619. In some embodiments, the notification system 617 may include a light or other visual indicator configured to indicate the status of the disinfection cycle (e.g., the "on" or "off" condition of the UV light source 620). In other embodiments, the notification system 617 may include an auditory indicator to indicate the status of the disinfection cycle. In other embodiments, the notification system 617 may include both a visual indicator and an auditory indicator.

[0153] Figure 6B A medical disinfection system 602 according to other embodiments is shown, which may be similar toFigure 6A Some features and functionality of the medical disinfection system 601. The medical disinfection system 602 includes a CPAP system 650, and the CPAP system includes a CPAP module 654 operatively coupled to a pipe member 655. A UV light system 619 is incorporated into the CPAP system 650 such that the CPAP module 654 manages the operation of the UV light system 619. The UV light system 619 includes an elongate member 632 having one UV light source 620 or more (1, 2, 3, or more) UV light sources 620 coupled thereto. During use, the elongate member 630 including the UV light source 620 is advanced along the pipe member 655 such that the UV light source 620 can project UV light onto the interior 655A, that is, expose the interior 655A to the UV light 621. In some embodiments, the UV light source 620 may be located at the free end 633 of the elongate member 632. The elongate member 632 may include a stylet, a detector, an endoscope, or any other suitable elongate device configured to be advanced within the pipe member 655. The UV light system 619 receives power from the CPAP module 654.

[0154] The UV light source 620 (including the elongate member 632) is configured to automatically advance and retract within the pipe member 655. More specifically, an actuator (not shown) of the CPAP module 654 can insert the UV light source 620 into the pipe member 655 between CPAP events to disinfect the pipe member 655. In some embodiments, the UV light source 620 includes a single light source 620 at the free end 631 such that during the advancement and / or retraction of the UV light source 620 along the length of the pipe member 655, the UV light source 620 disinfects a portion or section of the interior 655A. In other embodiments, the UV light source 620 includes a plurality of UV light sources 620 arranged along the length of the elongate member 632. In such other embodiments, the UV light source 620 can disinfect the interior 655A after the elongate member 632 is advanced within the pipe member 655 and before the elongate member 632 is retracted from the pipe member 655. In some embodiments, when the elongate member 632 is not disposed within the pipe member 355, that is, between disinfection events, the CPAP module 654 can accommodate the elongate member 632.

[0155] In some embodiments, the light source 620 may include a light-emitting diode (LED) 620A at the free end 633. In other embodiments, the light source 620 may include a light-emitting diode 620B disposed within the CPAP module 654. In such other embodiments, the elongate member 632 may be configured to propagate UV light 621 along the elongate member 632 and project the UV light 621 away from the elongate member 632. In some embodiments, the light source 620 may include an optical fiber extending along the elongate member 632. In some embodiments, the notification system 617 may be incorporated into the CPAP system 650.

[0156] Since the UV light system 619 is incorporated into the CPAP system 650, the UV light system 619 may be configured to automatically initiate a disinfection cycle based on the operation of the CPAP system 650. For example, the UV light system 619 may automatically initiate a disinfection cycle between CPAP events or according to a defined schedule, such as during a non-sleep period of the user.

[0157] In some embodiments, the UV light system 619 may include a sensor 660 configured to detect contamination of the tubing 655. In such an embodiment, the UV light system 619 may be configured to initiate a disinfection cycle based on the detection of contamination. For example, the UV light system 619 may be configured to initiate a disinfection cycle only when contamination of the tubing 655 is detected. The sensor 660 may include, for example, any suitable sensor for detecting contamination, such as an optical sensor, a capacitance sensor, an inductance sensor, or an ultrasonic sensor.

As an alternative or supplement to the elongate member 632, the UV light system 619 may include a plurality of UV light sources 620C disposed along the interior 655A of the tubing 655. In such an embodiment, the UV light sources 620C may be fixedly attached to the interior 655A (i.e., the inner surface) of the tubing 655. The UV light sources 620C may be configured to expose the entire interior 655A to UV light 621 to disinfect the entire interior 655A. The UV light sources 620C may be electrically coupled to and receive power from the CPAP module 654.

The package 1000 is generally configured to effect sterilization of one or more medical devices within the package 1000 via exposure to UV light 1021 that may be projected from an external UV light source 1020. Accordingly, the package 1000 is configured for exposure to UV light 1021, where the UV light 1021 is configured to sterilize medical devices.

[0175] The package 1000 generally includes a container 1010 and a lid 1011. The container 1010 includes a plurality (e.g., 1, 2, 3, or more) of compartments, such as a first compartment 1010A and a second compartment 1010B. A first medical device 1030A is disposed within the first compartment 1010A, and a second medical device 1030B is disposed within the second compartment 101B. Each of the first medical device 1030A and the second medical device 1030B is configured to be sterilized (e.g., bactericidal) via exposure to a dose of UV light 1021. In some embodiments, the UV light dose is defined by a combination of UV light intensity and exposure duration. In some embodiments, a medical device may require at least a defined dose (or dose range) of UV light for adequate sterilization. Additionally, in some embodiments, a medical device may be damaged by a UV light dose that exceeds the defined dose (or dose range). Further, some medical devices may require a greater dose than other medical devices. In the illustrated embodiment, the first medical device 1030A is configured to receive a first dose of UV light 1021 to sterilize the first medical device 1030A, and the second medical device 1030B is configured to receive a second dose of UV light 1021 to sterilize the second medical device 1030B. For purposes of description, the second dose is greater than the first dose. The container 1010 is configured to facilitate exposure of the first medical device 1030A and the second medical device 1030B to UV light 1021. The inner wall surface 1010C may be configured to reflect the UV light 1021 such that substantially the entire first medical device 1030A and the second medical device 1030B are exposed to the UV light 1021.

[0176] The lid 1011 is generally configured to hold a first medical device 1030A and a second medical device 1030B in a first compartment 1010A and a second compartment 1010B, respectively. The lid 1011 is removably coupled to the container 1010 so as to extend across the open ends (e.g., open top ends) of the first compartment 1010A and the second compartment 1010B. In the illustrated embodiment, the lid 1011 includes a first lid portion 1011A that extends across the open end of the first compartment 1010A and a second lid portion 1011B that extends across the open end of the second compartment 1010B. In use, a user can peel the lid 1011 from the container 1010 to gain access to the first medical device 1030A and the second medical device 1030B. The first lid portion 1011A and the second lid portion 1011B can be removed separately from the first compartment 1010A and the second compartment 1010B, respectively.

[0177] In some embodiments, the lid 1011 can be configured to allow UV light 1021 to transmit through the lid 1011. In the illustrated embodiment, the first lid portion 1011A is configured to allow a first dose of UV light 1021 to enter the first compartment 1010A (i.e., pass through the first lid portion 1011A) to disinfect the first medical device 1030A. Similarly, the second lid portion 1011B is configured to allow a second dose of UV light 1021 to enter the second compartment 1010B (i.e., pass through the second lid portion 1011A) to disinfect the second medical device 1030B.

[0178] Figure 10B is a detailed cross-sectional view of a portion of the lid 1011 taken along section line 10B-10B Figure 10A In some embodiments, the lid 1011 includes, for example, a plurality (e.g., 1, 2, 3 or more) of layers 1012, such as a first layer 1012A, a second layer 1012B, and a third layer 1012C. The first layer 1012A, the second layer 1012B, and the third layer 1012C are configured to be removed separately from the container 1010. For example, in a first case, a user can remove the first layer 1012A, leaving the second layer 1012B and the third layer 1012C in place. In a second case, a user can remove the first layer 1012A and the second layer 1012B, leaving the third layer 1012C in place.

[0179] Layers 1012 can each be configured to limit or control the transmission of UV light 1021 through the lid 1011. For example, the first layer 1012A can be configured to prevent the transmission of UV light 1021, and the second layer 1012B and the third layer 1012C can be configured to allow limited transmission of UV light 1021. As an example, a user can remove the first layer 1012A from the first lid portion 1011A. In such a case, the remaining second layer 1012B and third layer 1012C can allow a first dose of UV light 1021 to enter the first compartment 1010A to disinfect the first medical device 1030A. As another example, a user can remove the first layer 1012A and the second layer 1012B from the second lid portion 1011B. In such a case, the remaining third layer 1012C can allow a second dose of UV light 1021 to enter the second compartment 1010B to disinfect the second medical device 1030B.

In some embodiments, different subsets of the UV light paths 1040 can be configured to transmit different doses of UV light 1021. For example, the first UV light path 1040A can be configured to transmit a first dose of UV light 1021 into (i.e., allow a first dose of UV light to enter) the first compartment 1010A. Similarly, the second UV light path 1040B can be configured to transmit a second dose of UV light 1021 into the second compartment 1010A.
