The field of the disclosure generally relates to principles of disinfection—which may include one or more of sanitization, sterilization, and cleaning—debridement, treatment of tissue wound surfaces with agents, optical and acoustic treatments with or without pharmaceutical/chemotherapeutic agents. The individual treatment or combination treatment may enhance existing single module treatment for management of cleansing disinfection, wound tissue care, etc.
Generally, improperly disinfected (e.g., sterilized) objects can be harmful to patients and/or users as the objects can potentially transfer or spread harmful agents (e.g. bacteria). In some instances, deaths have been caused by improperly sterilized objects. For example, an amoeba was introduced to patients' brains by the use of nasal rinsing apparatus having contaminated water. Additionally, improperly sterilized medical instruments have been known to transmit drug-resistant bugs and/or bacteria in hospitals possibly due to a complete removal of a bioburden. There is a need for systems and methods of sterilizing objects used on or by patients.
In one aspect, a disinfecting system includes a housing. An ultraviolet light (UV) source is secured to the housing and configured to emit UV light for disinfection of a target. A processor is secured to the housing in communication with the UV light source. The processor is configured to activate the UV light source for a selected amount of time suitable for disinfection of the target.
The features, functions, and advantages that have been discussed can be achieved independently in various embodiments or may be combined in yet other embodiments, further details of which can be seen with reference to the following description and drawings.
The systems and methods described herein enable disinfecting of a target (e.g., one or more of an object, a surface, material, and matter) using ultraviolet (UV) light and/or ultrasound. As used herein, disinfecting and disinfection of the target means the ability to kill and/or destroy some or all infectious agent(s) at/on the target. Thus, disinfecting may include sterilization or sanitization, though not necessarily. The ultraviolet is configured to be effective in retarding growth, destroying, and/or killing infectious agents. As used herein, “infectious agent” or “infectious agents” refers to any organism that causes disease in a host including, but not limited to, a virus, bacterium, bacteria, prion, fungus, parasite, and disease (e.g. toxoplasmosis).
Ultraviolet light, such as ultraviolet C (UVC; i.e., electromagnetic radiation or light having a wavelength from about 100 nm to about 280 nm, such as 254 nm), has been known to have a microbicide and bactericidal effects on air, liquids, and surfaces. In some embodiments, a wavelength set to 254 nm is effective at eliminating bacteria (e.g. Naegleria fowleri) in the following lifecycle stages: Cyst, trophozoite, and flagellate. In such embodiments, the ultraviolet (UV) dosage utilized for the inactivation of the N. fowleri in water is 63 mW.sec/cm2. Other electromagnetic radiation wavelengths may also be effective for disinfecting, sanitizing and/or sterilizing, including but not limited to wavelengths from about 270 nm to about 320 nm.
In one embodiment, ultraviolet light is transmitted in and around the embodiments described herein through an ultraviolet LED or LED array. In some embodiments, the LED is flexible and capable of flush securement on non-planar surfaces. Additionally, the LED array may be fabricated on a flexible strip. In some embodiments, a non-pulsed output is provided with the intensity controlled by a current limiting resistor in series with the LED. Alternatively, the UV light can be transmitted in any manner that facilitates sterilization as described herein, including but not limited to, a fluorescent UVC bulb and a laser. The ultraviolet LED(s) described herein can have a wavelength range of 100-400 nm. In some embodiments, a wavelength at 240-260 nm is preferred (i.e. for DNA absorption and/or bacteria/virus reduction), or at 365 nm (i.e. for water sterilization or treatment). Alternatively, the UVC described herein and used in various embodiments can scan in any suitable wavelength range that facilitates disinfection, sanitation, and/or sterilization as described herein. In the exemplary embodiment, a single or multiple sensors could be used to monitor temperature, power, pH, and/or other parameters needed to determine if the object that is subject to disinfection, sanitation, and/or sterilization is safe to use. The treatment time may be automated, and the movement of the UV light source and/or the object to be treated may be automated. For example, a robot or other device may automated movement of the UV light source and/or object to be treated.
In one embodiment, the battery used to power circuits 100 and 110 could be charged using AC\DC wall adapter or wireless charging technology.
In addition to the sterilization provided by UV, ultrasound can be combined with the UV to clean and/or sterilize objects.
In some embodiments, a frequency range of the ultrasound is adjusted to target specific infectious agents. In one embodiment, the ultrasound is adjusted in the frequency range from 20 kHz to 3 MHz. Alternatively, the frequency range can be any range that facilitates sterilization as described herein. In the exemplary embodiment, the drive signal is selected to have a predetermined output based on the target object. For example, the predetermined output of the drive signal can be constant, pulsed, and/or modulated to obtain the desired results. The ultrasonic device can be made of many different constructions including, but not limited to, bolt clamped Langevin or piezoelectric discs. In some embodiments, one or more sensors are used to monitor at least one of temperature, power, pH, and other parameters needed to determine if the ultrasound is or has been effective in sterilizing an object.

Utilizing light source 222 and/or transducer enables dispenser 200 to sanitize fluid within the dispenser and/or the inner walls of the dispenser. Treating and/or sanitizing water prior to using dispenser 200 will reduce the risk of being infected with infectious agents (e.g. the PAM disease). In one embodiment, the fluid (e.g. water) is treated for a specified amount of time with the light source 222 before use of dispenser 200. In some embodiments, the fluid (e.g. water) is treated for a specified amount of time with ultrasound emitted from transducer 224 before use of dispenser 200. The treatment times of UV and/or ultrasound and the frequencies of the ultrasound can be specified to target a specific infectious agent. In one example, the light source 222 and the ultrasound transducer 224 may be operated simultaneously to disinfect the dispenser 200. Bubbles in the fluid caused by the ultrasound transducer 224 may assist disinfection by the light source 222. In another example, the light source 222 and the ultrasound transducer 224 may be used at different times, independent of one another. Additionally, the light source 222 could also be used to sanitize the dispenser 200 after each use. In some embodiments, one or more sensors 240 are positioned in dispenser 200 to monitor at least one of temperature, power, pH, and other parameters needed to determine if the UV and/or ultrasound is or has been effective in sterilizing the dispenser 200 and/or the fluid within the dispenser 200.

In the exemplary embodiment, glove 420 is fabricated to have an opaqueness that blocks UV light from being transmitted to the skin of a wearer. System 400 enables a user to sanitize a glove that would normally require disposal. For example, a medical professional could utilize 1 set of gloves 420 for examining different patients with the use of glove sanitizer 401 to sanitize the gloves between patients. Likewise, a user in a food processing facility would be able use 1 set of gloves between different foods with the use of glove sanitizer 401 to sanitize the gloves between work areas. System 400 provides cost effective way to prevent infectious agent transmission with a decrease in waste. Such a system would also enable health care professionals to potentially avoid the requirements of constant use of sterilizing agents on the skin. The glove sanitizer 401 may include a shield to inhibit a user's eyes from being exposed to UV light.

Likewise, the application is configured to receive information from sanitizers 1304 and 1402 and sensors associated with device 1302 and 1402 to provide execution instructions. For example, a user may select to run a sanitizing protocol for kitchen counters. The application would determine the amount, power, and duration of UVC needed to kill infectious agents associated with kitchen counters. The sanitizers 1304 and 1402 can be associated with a robot or other device for automatically moving the sanitizers during treatment session. It should be noted that infectious agent data could be pulled from a data source retained locally on device 1302 and 1404 or on a remote storage location that is communicatively coupled to the device.
Once the application has determined the amount, power, and duration of UVC required for a particular protocol, a session is initiated or held until a user interacts with device (e.g. starts the session). During the session, sensors (e.g. accelerometer, magnetometer, gyroscope, proximity sensor, and camera) in device 1302 and 1402 are utilized to provide feedback as to the effectiveness of the session. The application can alert a user as to whether a surface and/or object has been in contact with a surface long enough to be sterilized and/or if a rate of speed of the sanitizer 1304 and 1402 is too fast or too slow to achieve a desired result. The feedback can be in any form provided by device 1302 and 1402 including but not limited to, visual and auditory signals.
In one embodiment, an inlet 1510 and an outlet 1512 for fluid extends through housing 1502 and into tub 1504. Inlet 1510 and outlet 1512 may provide fresh fluid and fluid circulation before, during, and/or after a sterilization session. A pump may be connected to the inlet 1510 and/or a vacuum source may be connected to the outlet 1512. One or more valves may be connected to one or both of the inlet 1510 and the outlet 1512. A controller may control the filling of the tub 1504, and/or the circulation of the fluid, and/or the removal of the fluid from the tub. Alternatively, fluid may be manually provided to tub 1504 without the use of inlet 1510 and outlet 1512. In one embodiment, a switch 1514 is coupled to housing 1502 to initiate the use of the transducers and/or light source 1508. Alternatively, a remote device (e.g. smartphone, tablet, laptop, and PC) could provide instructions to sterilizer 1500.
In the exemplary embodiment, all components of sterilizer 1500 are sterilizable and seals and/or gaskets 1520 are used enable sterilizer 1500 to be autoclaved and placed in the sterile field during surgery. As such, electronics such as circuits 100, 110, 120, 130, and 140 could be kept outside the sterile field. In addition to cleaning and/or sterilizing surgical instruments, sterilizer 1500 could also be utilized to clean parts of a body, (e.g. treating or cleaning diabetic wounds) and sterilizing and/or cleaning food in an industrial or residential setting.

Generally, UVC 260-340 nm can disrupt both DNA and RNA. This requires a specific direct line of site as well as a specific type. It has a depth of penetration. Treatment modalities would require this direct line of sight, specific time interval, depth of penetration, and specific exposure. This could be done through direct light, reflective light, specific movement or compression of the material so it becomes closer to the light source.
In addition, acoustic therapy/ultrasound can provide vibratory/debridement type treatment. This treatment in combination with UVC or in isolation may allow debridement material where similar modules can be removed or separated in existing ultrasonic cleaner or can be utilized in combination with chemical agents or pharmaceutical agents. Ultrasound may also have the potential to affect permeability of cell walls, membrane, i.e. bacterial cell walls, or blood brain barriers for example in dura which may enhance penetration of existing pharmaceutical or chemotherapy agents or chemical agents to enhance the ability to sterilize or clean tissue. Also the vibratory component may allow in combination with UVC less time or more direct light exposure.
UVC can be applied to traditional light, LED with battery operated, or laser to increase the depth of penetration. UVC can be battery powered or externally powered through electromagnetic waves to allow implantable device to be turned on or off. Ultraviolet light can have deleterious effects to other tissue as it can affect DNA and RNA. Pharmaceutical or other materials and/or chemicals, such as H2O2, may be added to the surface being treated.
The light optical or acoustic also has a depth of penetration, intensity of the light and duration. It could be integrated via computer and software programs to be able to turn on and off or be mobile. In addition, UVC and/or ultrasonic can be applied via robotic mechanism so they can be selectively moved whether in the body, in a room or specific space with a timer and location so one can provide timing/direct light of sight (reflective sight) or movement closer or farther as needed to enhance sterilization for topical effect. UVC could be applied via robotic control such as robotic floor cleaner or surface cleaner or via remote control drone type of device. It could also have motion sensors that could allow when movement is detected to be turned on or off so it is not damaging any living tissue in animals, people, etc.
This single or composite treatment may have use of pharmaceuticals (i.e. antibiotics or bacteriocidal) or can enhance the efficacy of the effect of pharmaceutical by applying UVC, ultrasound treatment, composite treatment, acoustic treatment, and/or optical treatment to enhance the efficacy of target agent for pharmaceutical. For example, ultrasound may open the cell wall membranes or bacterial wall membranes previously persistent antibiotics now can become toxic to the bacteria via the application of UVC or acoustic/ultrasound phenomenon. Vibratory or optical treatments may open the cell wall membranes to allow pharmaceutical/chemical agents to penetrate where previously the bacteria or cells were resistance to this and allow better depth of penetration. Resistant pharmaceutical agents may now become toxic to the bacteria, viruses, parasites, etc. Individuals could wear shields to eyes such as specific sunglasses to tune out UV or it could be motion censored or detect heat/movement to turn on or off either via remote control or via computer control. This could be linked to a control system that could also allow local pharmaceutical/chemotherapeutic agents whether inside the body or on a specific surface. We could also time so that chemical agents and/or UVC could be administered simultaneously i.e. spraying 60% alcohol and/or H2O2 as well as UVC at the same time so it would coat a body surface to sterilize it. This could be used for example for gloves which are placed on individual's hands. The gloves could have an optical shield in them so the UVC would not penetrate through the gloves. The individual would wear gloves and for example work on a patient rather than changing gloves and going to the next patient. They would go under a shield where UVC would be applied and then spray 60% alcohol or greater preparation that would further sterilize the gloves. These would also be dried and then one could go on to the next patient. This would prevent damage to the skin as the gloves would be on and the gloves would have an opaque surface for UVC so that UVC would not penetrate through the skin with addition of alcohol or chemical agent to further sterilize from above and below so circumferential treatment of gloves so one would not have to change gloves constantly. The gloves intrinsically would have an agent that would prevent penetration of UVC into the skin or tissue. As UVC is applied, it would either be shielded or be opaque so one would simply scan their hands for a known period of time underneath this for light and/or chemical agent to be sprayed on. Either the movement alone would allow drying or there could be a small burst of air with fan, etc. that would dry this. The combination of two agents would then allow the gloves to be sterilized so that one would not have to change the gloves and can keep the gloves on when going from patient-to-patient or treatment-to-treatment with preparation, etc.
If one has solid debris, one could place it in a vibratory ultrasonic bath. The ultrasonic bath could have chemical agents in it, pharmaceutical agents, etc. or could simply vibrate the material. One could then pass under UVC so composite treatments would not only debride and move material but then also sterilize UVC. It also affects not just bacteria but would affect viruses, parasites, or any material that is RNA/DNA. There would need to be a specific type typically in range of second and then with or without chemical or pharmaceutical spray and then we would be able to utilize.
This could also be applied for example in the eye. Currently, Toxoplasma gondii is a toxic infection in the eye and can permanently damage retinal cells. Antibiotics have trouble going to the blood brain barrier and there is no treatment as these agents can hide within the parasites/toxoplasmosis. With UVC/laser, one could go through the eye and treat the parasites for a period of a second or two. It would focus on specific lesions that may have active parasites and selectively kill these. Otherwise, it is extremely difficult to assess. Otherwise, these are permanent parasites. This could also be used for target laser and other type of parasites. It would not allow visualization but endoscopically for example light source could be applied to the liver, cranial tissue, brain tissue, liver tissue, etc. where parasites/viruses live permanently. This could be effective for herpes type viruses and neurologic tissue and specifically target the parasitic DNA. Specific timers and energy frequencies could be utilized to avoid damaging body tissue while specifically focusing on RNA or DNA of the parasitic tissue, viral tissue, or bacteria. Again, this could be used with known pharmaceutical treatment or could be used in isolation. The vibratory or acoustic components could also be applied to provide further access especially if there is fluid or gelatin media could be applied. This could be staged or simultaneous.
If one is adopting the pill or agent which could be implanted or swallowed to effect local tissue, the acoustic/optical energy UVC could be turned on or off as needed. There could also be remote control so the pill could be sped up or slowed down for example to adjust the system rather than allowing normal parasitosis to push the pill through the digestive system. This could be slowed by external wavelengths or radiofrequency so they can move either with parasitosis faster or slower so it could target a specific location. There could also be timer for turning the acoustic/optical energy UVC on and/or off.
This could be implanted in the peritoneum. For example, it could be guided in the peritoneum either robotically or magnetically to a specific location for a specific period of time. This would allow optical/acoustic energy. This could also time release a pharmaceutical agent as well so this could be timed and moved to another location. This could be done under endoscopic guidance during a surgical procedure or this could be implanted surgically and then applied at specific intervals. Later, this device could be tracked and then removed either by MRI, x-ray, ultrasound, or other diagnostic. This could be implanted laparoscopically, endoscopically, arthroscopically into the joint. It could be used, for example, arthroscopically into a joint if one has calcium (chondrocalcinosis crystals) that coat the joint one could use this to move through the joint and selectively remove the calcium crystals from the articular cartilage. This could be selectively removed with vibratory frequencies over a period of time so it would not damage the articular cartilage cells but acoustically, optically, chemically, or with pharmaceutical agents could selectively release the calcium crystals so they can move to the articular cartilage. One could have articular cartilage previously damaged via coating of chondrocalcinosis crystals. This would selectively vibrate and remove the crystals. There are different modules or elasticity of calcium which would selectively be removed and then potentially be flushed out again through a surgical procedure or could be left inside the joint. As one moves, it could selectively go through different parts of the joint and selectively move either from cartilage, synovial tissue, etc. This could target other known coating agents i.e. biofilm. Biofilm has different module so elasticity and biofilm can separate from tissue such as a joint replacement. Acoustic energy with or without UVC could be applied. Again, this could be implanted, removed, placed during endoscopic or arthroscopic procedure. It could then be selectively turned on and off to selectively remove the biofilm, chondrocalcinosis, or other material coating from metallic implant, polymeric implant, or biologic tissue since they are different modules and different material. They would selectively separate. This could be flushed out with chemotherapy or pharmaceutical agents. This could also be used to separate tumor which is a rapidly growing cell that is typically stiffer, harder, and firmer than local tissue. One could use the UVC, ultrasound, and/or chemotherapeutic agents to selectively kill the stiffer tissue i.e. rapidly growing neoplasm/cancerous tissue. Since it is rapidly growing, DNA is more affected by UVC and RNA affected by UVC ultrasound, chemotherapeutic agents where this could be targeted and turned on/off selectively as diagnostic portion of ultrasound will measure the density of the tissue. The acoustic portion of ultrasound will separate the two and then either ultrasound UVC and/or chemotherapeutic agent applied locally to kill neoplastic tissue. This could then selectively be turned on/off depending on the diagnostic portion of the ultrasound which in frequency determines there is a slime i.e. biofilm, chondrocalcinosis, crystallin type tissue, or denser tissue i.e. rapidly growing tumor tissue that has different acoustic density or diagnostic density via MRI or other diagnostic test. This could be selectively turned on and off with implantable or surgically operated device. This could be robotically controlled externally. Other treatments can also be applied, including laser (optical), electrical (RF), mechanical (pressure, torque), ESW, chemical (ETOH, H2O2), and pharmaceutical (pH/acid based).
Examples of this are implied in other patents i.e. Bonutti Robotics, Bonutti MIS patents which we reference by incorporation.
This also could be applied locally to tissue or locally to surfaces via wireless or mobile phone—Smartphone technology. UVC could be built on or application for your mobile phone where a selective wavelength could be used via cellphone, mobile device, Ipad, etc. to treat a specific surface. There would be a timer, location, depth. It would measure the distance from a specific surface. It would turn this on or off. It would be shielded so it would not develop direct eye contact. It could sterilize, cleanse, treat surface via UVC and mobile phone. Mobile application could also be used display as a treatment device to turn on/off implantable device within the human body for sterilization treatment, chemotherapy, treatment of biofilm, etc. It could potentially be used to power the device. Chemotherapy agents or pharmaceutical agents could be applied by spraying, direct pressure, or solution to specific tissue as well.
