Description

[Background technology]

[0001] One of the challenges of modern medicine is the prevention of infection and the spread of microorganisms. One area where this challenge is constantly being presented is infusion therapy treatment. Infusion therapy is one of the most common forms of treatment. Hospitalized patients, home care patients, and other patients receive fluids, medications, and blood products through vascular access devices inserted into the vascular system. Infusion therapy can be used to treat infections, provide anesthesia or pain relief, provide nutritional support, treat cancerous growths, maintain blood pressure and heart rate, or for many other clinically important applications. Summary of the Invention [Problem to be solved by the invention]

[0002] In some cases, implantable ports can be placed under a patient's skin to allow for intravenous (IV) therapy and direct intravenous blood transfusion. As convenient as implantable ports are, the spread of microorganisms through the implantable port into a patient's veins is a major concern. Similar concerns exist for connectors on other medical devices, such as connectors at the proximal or distal ends of catheters. Therefore, there is a need for methods, systems, and devices for disinfecting medical devices and thereby preventing the spread of microorganisms into a patient's body. [Means for solving the problem]

In some embodiments, the one or more optical fibers may be embedded in a wall of the tube or end cap. In some embodiments, the ultraviolet light source may include one or more light emitting diodes (LEDs) or superluminescent diodes (SLEDs).

[0006] In some aspects, the housing may be configured to be held in a user's hand. In some aspects, the housing may be configured to be worn by a user (e.g., on an extremity such as an arm or leg). In some aspects, the disinfection device may include a pump disposed within the housing. In some aspects, the pump may be an infusion pump. In some aspects, the end cap may be configured to attach to a medical device.

DETAILED DESCRIPTION OF THE INVENTION

[0012] Before some specific embodiments are disclosed in more detail, it should be understood that the specific embodiments disclosed herein do not limit the scope of the concepts provided herein, and that the specific embodiments disclosed herein can have features that can be easily separated from the specific embodiment and optionally combined with or substituted for features of any of several other embodiments disclosed herein.

[0013] With regard to the terms used herein, it should also be understood that these terms are intended to describe certain specific embodiments and are not intended to limit the scope of the concepts provided herein. Ordinal numbers (e.g., first, second, third, etc.) are generally used to distinguish or identify different features or steps within a group of features or steps and do not provide sequential or numerical limitations. For example, "first," "second," and "third" features or steps do not necessarily have to appear in that order, and a particular embodiment including such features or steps is not necessarily limited to three features or steps. Designations such as "left," "right," "up," "down," "front," and "rear" are used for convenience and do not imply, for example, a specific fixed location, orientation, or direction. Instead, such designations are used to reflect, for example, a relative location, orientation, or direction. The singular forms "a," "an," and "the" include plural referents unless the context clearly dictates otherwise.

[0014] With respect to "proximal," for example, a "proximal portion" or "proximal end portion" of a device disclosed herein includes a portion of the device intended to be near the user (e.g., a holder for the device). Similarly, for example, a "proximal length" of a device includes the length of the device intended to be near the user. For example, a "proximal end" of a device includes the end of the device intended to be near the user. A proximal portion, proximal end portion, or proximal length of a device may include the proximal end of the device. However, a proximal portion, proximal end portion, or proximal length of a device need not include the proximal end of the device. That is, unless the context suggests otherwise, a proximal portion, proximal end portion, or proximal length of a device is not a terminal portion or terminal length of the device.

[0015] With respect to "distal," for example, a "distal portion" or "distal end portion" of a device disclosed herein includes the portion of the device intended to be opposite the user (e.g., "away from" the user) relative to the proximal portion. Similarly, for example, a "distal length" of a device includes the length of the device opposite the proximal portion and intended to be away from the user. For example, the "distal end" of a device includes the end of the device intended to be opposite the proximal end. A distal portion, end portion, or length of a device may include the distal end of the device. However, a distal portion, end portion, or length of a device need not include the distal end of the device. That is, unless the context suggests otherwise, a distal portion, end portion, or length of a device is not a terminal portion or length of a catheter.

[0016] The term "logic" may refer to hardware, firmware, or software configured to perform one or more functions. As hardware, the term logic may refer to or include circuitry having data processing and / or storage capabilities. Examples of such circuitry may include, but are not limited to or restricted to, a hardware processor (e.g., a microprocessor, one or more processor cores, a digital signal processor, a programmable gate array, a microcontroller, an application-specific integrated circuit "ASIC," etc.), semiconductor memory, or combinational elements.

[0017] Additionally or alternatively, the term logic may refer to or include software, such as one or more processes, one or more instances, application programming interfaces (APIs), subroutines, functions, applets, servlets, routines, source code, object code, shared libraries / dynamic link libraries (DLLs), or one or more instructions. This software may be stored on any type of suitable non-transitory or transitory storage medium (e.g., electrical, optical, acoustic, or other forms of transmission, such as carrier waves, infrared, or digital signals). Examples of non-transitory storage media may include, but are not limited to, programmable circuits, non-persistent storage devices such as volatile memory (e.g., any type of random access memory “RAM”), or persistent storage devices such as non-volatile memory (e.g., read-only memory “ROM,” power-backed RAM, flash memory, phase-change memory, etc.), solid-state drives, hard disk drives, optical disk drives, or portable memory devices. As firmware, logic may be stored on persistent storage devices.

[0018] The embodiments described herein are generally directed to a disinfection device capable of disinfecting the hubs of medical devices. For example, the disinfection device may be used to disinfect one or more hubs of a multi-lumen catheter, an infusion catheter, a port, or other medical device. In some aspects, the one or more hubs may include a male or female Luer connector.

[0019] The germicidal or biocidal effects of ultraviolet (UV) radiation have been known since the late 19th century. In recent years, the use of UV radiation has gained widespread acceptance in the fields of water and air purification, and has found some limited application in food processing and the sterilization of medical devices.

[0020] UV light consists of high-energy photons that occupy wavelengths between 200 and 400 nanometers in the electromagnetic spectrum. This means that UV light emits slightly less energy than soft X-ray radiation (which, for example, has photon energies of 100 to 1000 electron volts, or eV), but significantly more energy than visible light. Rather than killing pathogens directly, UV energy inhibits their ability to reproduce by triggering a photochemical reaction with their genetic structure, thus effectively killing them.

[0021] The amount of energy emitted by UV light is inversely proportional to its wavelength; therefore, the shorter the wavelength, the greater the energy produced. Generally, the UV light portion of the spectrum consists of three segments: UV-A (315-400 nm), used in tanning lamps; UV-B (280-315 nm); and UV-C (200-280 nm). The UV-B and UV-C regions contain wavelengths with the greatest germicidal activity. Research has shown that the most effective wavelengths for killing microorganisms are between 250 and 265 nm.

[0022] Reference is now first made to FIG. 1 , which illustrates a disinfection device 100 for disinfecting at least a portion of a medical device. The disinfection device 100 may include a housing 102. The housing 102 is configured to fit in a user's hand. The housing 102 may include a button or switch 110 that can turn on or activate the disinfection device 100. Disposed within the housing 102 are a rechargeable power source 114 and an ultraviolet light source 116. In some embodiments, the rechargeable power source 114 may include a battery, a capacitor, or an inductance coil. In some embodiments, the housing 102 may be configured to connect to a cable, such as a USB cable, via a port 117 to recharge the power source 114. In some embodiments, the rechargeable power source 114 may be configured to be recharged wirelessly, for example, by inductive charging.

[0023] In some embodiments, information may be uploaded from or downloaded to the sterilization device 100 via port 117. In some embodiments, port 117 allows for connection to an external device, such as a CPU. In some embodiments, the external device may be configured to hold information regarding the use of the sterilization device 100. For example, the external device may store information regarding each medical device being sterilized, settings related to sterilization during each sterilization routine, when each sterilization routine occurs, and any other desired parameters. In some embodiments, the external device may include one or more ultrasound machines, imaging devices, catheter placement devices, hospital emergency medical record (EMR)-connected medical devices, communication devices, revalidation systems, ventilators, and infusion systems.

[0024] The housing 102 may also include one or more indicators 112 that can be used to indicate the status of the sterilization device 100. The one or more indicators 112 can provide an indication of the operational status of the sterilization device 100. For example, the one or more indicators 112 may be configured to illuminate when the device 100 is powered on to indicate that the ultraviolet light source 116 is running, and to flash when disinfection of the attached medical device is complete. While three indicators are shown, it is understood that more or fewer indicators may be provided. The one or more indicators 112 may include visible light spectrum light emitting diodes having at least one color. In some embodiments, the one or more indicators 112 may be configured to have two or more colors. In some embodiments, the one or more indicators 112 may indicate the level of disinfection of the attached medical device. In some cases, the one or more indicators 112 may flash to indicate the stage or level of disinfection of the attached medical device. In some embodiments, the one or more indicators 112 may include two or more colors, where the color indicates the stage or level of disinfection of the hub of the medical device. For example, in some embodiments, a red light may indicate incomplete or insufficient disinfection, while a yellow light may indicate an intermediate or active process of disinfecting the attached hub, and a green light may indicate sufficient or complete disinfection.

[0025] One or more indicators 112 may be further programmed to flash or otherwise exhibit a lighting pattern to further communicate the status of the sterilization device 100. For example, one or more indicators 112 may be programmed to exhibit a lighting pattern indicating low battery. In some embodiments, one or more indicators 112 may be further programmed to indicate an error or mechanical malfunction. In some cases, one or more indicators 112 may be programmed to indicate that the sterilization device 100 is ready to connect with at least some of the medical devices. Information to the user may be provided by a display screen (not shown), such as an LCD screen, that displays run time, sterilization status, battery level, or other such status notification, instead of the one or more indicators 112.

[0026] In some embodiments, the housing 102 may be formed from an easily cleanable material so that the sterilization device 100 can be cleaned after each use. In some embodiments, the housing 102 may be formed from a sterile or microorganism-resistant material.

[0027] The sterilization device 100 may include an ultraviolet light source 116 located within the housing 102. The ultraviolet light source 116 may take the form of one or more LEDs, SLEDs, or other ultraviolet light-generating devices. The ultraviolet light source 116 is capable of generating ultraviolet light or radiation to neutralize any microorganisms in or around at least a portion of the medical device coupled with the end cap 106. In some aspects, the ultraviolet light source 116 comprises a germicidal lamp. In some aspects, the ultraviolet light source 116 may comprise a UV light-emitting diode having a peak wavelength within the UV-C range of 200-280 nm (in some embodiments, 225-265 nm). As used herein, the term "ultraviolet light source" is used to refer to a lamp, light-emitting diode (LED), superluminescent diode (SLED), laser, or another similar technology capable of emitting wavelengths in the range of approximately 100 nm to 400 nm and / or capable of killing pathogens.

[0028] In some examples, the UV light source 116 may be configured to emit UV light in a range of about 200 nm to about 280 nm, which generally corresponds to the so-called UV-C range, although the UV light source 116 need not be limited to the UV-C range. Indeed, the UV light source 116 may be configured to emit UV light anywhere within the UV portion of the electromagnetic spectrum. In one example, the UV light source 116 may alternatively be configured to emit UV light in a range of about 280 nm to about 315 nm, which corresponds to the so-called UV-B range. In another example, the UV light source 116 may alternatively be configured to emit UV light in a range of about 315 nm to about 400 nm, which corresponds to the so-called UV-A range. Considering that the UV light source 116 is configured to emit UV light in the UV-C range, the UV light source 116 may be, for example, a low-pressure mercury lamp having an emission peak at 254 nm, an excimer lamp having an emission peak at 222 nm, a pulsed xenon lamp, or one or more LEDs that can independently have emission peaks at, for example, 265, 273, or 280 nm.

[0029] The tube 104 includes a first end 103 that is connected or attached to the housing 102. The tube 104 may penetrate a wall of the housing 102 and enter the interior of the housing 107. The second end 105 of the tube 104 is free from and located away from the housing 102. An end cap 106 is disposed at the second end 105 of the tube 104. Ultraviolet light emitted from the ultraviolet light source 116 within the housing 102 is transmitted through the tube 104 to the end cap 106 to disinfect at least a portion of a medical device attached to, surrounded by, or coupled to the end cap 106. The end cap 106 may take the form of a hub or other connection device. In some embodiments, the end cap 106 may include one or more luer connectors, barbed ports, or clamps. In some embodiments, the end cap 106 may include a threaded connection. In some embodiments, end cap 106 may be one of multiple end caps and may include one or more bends or elbows.

[0030] In some aspects, the tube 104 may include a reflective material configured to reflect or direct ultraviolet light emitted from the ultraviolet light source 116 toward the end cap 106. In some embodiments, the inner surface of the tube 104 may include an ultraviolet (e.g., UV-C) reflective material or other material with high UV reflective properties. The ultraviolet reflective material may be provided to retain and reflect any ultraviolet radiation emitted by the ultraviolet light source 116 within the housing 102, thereby directing the ultraviolet radiation toward the end cap 106 for disinfecting portions of a medical device coupled or associated with the end cap 106.

[0031] In some embodiments, the tube 104 may include one or more optical fibers that transmit light from the ultraviolet light source 116 to the end cap 106. In some embodiments, the tube 104 may include multiple lumens. In such a configuration, a first lumen may be configured to transmit ultraviolet light, while another lumen is configured to transmit fluid from a first location to a second location. In some embodiments, one or more optical fibers may be optical fibers that include a Bragg grating, in which the refractive index within the core of the optical fiber varies along its length to reflect certain wavelengths and transmit other wavelengths. The one or more optical fibers may extend into the end cap 106 and be configured to optimize a target distribution pattern. The one or more optical fibers may be arranged in different configurations to maximize ultraviolet light transmission to the portion of the medical device requiring sterilization.

[0032] 1, an end cap 106 may be attached to a first hub 108 of a medical device. The sterilization device 100 can sterilize at least a portion of the first hub 108 attached to the end cap 106. After sterilizing the first hub 108, the sterilization device 100 can be attached to a second hub 109 of the medical device to sterilize at least a portion of the second hub 109.

[0033] In some embodiments, the sterilization device 100 may include a memory and may be pre-programmed with exposure times and power settings to ensure disinfection of various medical devices. The sterilization device 100 may include a processor 118 configured to control the ultraviolet light source 116 to run at a desired power for a desired duration depending on the type of medical device needing cleaning. In some embodiments, the sterilization device 100 can recognize the type of medical device needing cleaning upon connection to the end cap 106 and further initiate a pre-set sterilization routine that applies the appropriate ultraviolet exposure to ensure disinfection.

[0034] In one embodiment, the sterilization device 100 may include a sensor, camera, radio frequency identification (RFID) reader, barcode scanner, transmitter, or transceiver to assist in identifying medical devices requiring sterilization. In some embodiments, the sensor, camera, barcode scanner, transmitter, or transceiver may enable wireless communication between the end cap 106 and the processor 118. In some embodiments, the sensor, camera, barcode scanner, transmitter, or transceiver may utilize the BLUETOOTH® protocol. For example, various medical devices may be provided with a barcode, barcode (e.g., a matrix barcode such as a “QR Code®”), RFID tag, or other descriptive information that can be received by the sterilization device 100 upon connecting the hub to the end cap 106. Upon identification, the sterilization device 100 may execute an appropriate pre-set sterilization routine. In such a configuration, the functionality of the device 100 may be fully integrated with the end cap 106. That is, the device 100 may be operable simply by connecting the end cap 106 to a portion of a medical device without any additional user input. In some examples, the identification of the medical device to be sterilized may be associated with a particular patient so that information surrounding the sterilization process of the patient's medical device can be transmitted and stored in the patient's medical record. This may allow a medical specialist to verify that the sterilization process was performed on a regular basis. Additionally, alerts may be pre-configured within the medical record system so that a medical specialist is periodically alerted to sterilize a particular patient's medical device. For example, the alert may indicate a particular patient, a particular medical device, a particular date, a particular sterilization process, and / or a sterilization device capable of providing the required sterilization process. Of course, such alerts may include additional information (e.g., room number, attending medical specialist, etc.) and may be "snoozed" or delayed based on various circumstances, such as the patient's medical condition or the delivery of fluids, medications, or other treatments via the medical device to be sterilized.

[0035] The sterilization device 100 may be configured to be powered on manually or automatically. In one aspect, the sterilization device 100 may be powered on and begin irradiating the medical device with ultraviolet light by activating a button or switch 110. In another aspect, the sterilization device 100 may be configured to automatically power on and begin a sterilization regimen when a medical device is attached to the end cap 106. Conversely, the sterilization device 100 may stop operating when a medical device is detached or removed from the end cap 106.

[0036] 2 shows the sterilization device 100 being used to sterilize a connector 120 of a catheter 122. The end cap 106 may be configured to couple with the connector 120 to transmit ultraviolet radiation from an ultraviolet radiation source within the housing 102 to the connector 120 to kill any potential pathogens or bacteria located on or within the connector 120. The catheter 122 may include any type of catheter configured to be placed within a patient's body, remove a substance from a patient's body, or introduce a substance into a patient's body. For example, the catheter 122 may be an infusion catheter, a urinary catheter, a urinary catheter, a sensing catheter, or any other type of catheter for placement on or within a patient's body.

[0037] 3 shows the sterilization device 100 being used to sterilize a connector 130 of a port 134. The end cap 106 is configured to couple with the connector 130 to transmit ultraviolet radiation from an ultraviolet radiation source within the housing 102 to the connector 130 to kill any potential pathogens or bacteria located on or within the connector 130. The port 134 may include any permanent or temporary port for accessing a patient's body.

The housing 402 may include a slot or recess 422 configured to secure a belt or strap 420. The belt or strap 420 may be configured to encircle a limb to attach the housing 402 to the limb.

[0040] The wearable disinfection device 400 may include an ultraviolet light source 416 located within the housing 402. The ultraviolet light source 416 may take the form of any ultraviolet light source, such as those described above. A tube 404 includes a first end 403 connected or attached to the housing 402. In some embodiments, the tube 404 may extend into the housing 402 to directly connect with the ultraviolet light source 416. A second end 405 of the tube 404 is free and spaced apart from the housing 402. An end cap 406 is disposed on the second end 405 of the tube 404. Ultraviolet light emitted from the ultraviolet light source within the housing 402 is transmitted through the tube 404 to the end cap 406 to disinfect at least a portion of a medical device secured to, surrounded by, or otherwise coupled to the end cap 406.
