Patent Application

Ectoparasites, including lice, fleas, etc., can infest and feed on human hosts and cause various problems for the host, including discomfort, irritation, and itching. For example, head lice (Pediculus humanus capitis) are insects that infest the heads of humans and grow to about the size of a sesame seed. Once in hair, the head lice lay eggs or “nits” in the hair of the host. The nits are small greyish-white oval-shaped eggs glued at an angle to the side of a hair shaft. A nymph may hatch from each egg or “nit” and grow and develop to an adult louse. Head lice infestations involve the colonization of the head or scalp of a host by the lice. Head lice feed on blood from the scalp and can cause irritation and itching for the host. Head lice are often spread to new hosts through direct head-to-head contact with an infested person or by sharing personal articles such as hairbrushes, combs, nit combs, or the like.
Treating ectoparasite infestations and/or head lice infestations may involve the application of topical treatments, including hair washing, or the application of lotions, oils, or the like. Manual removal of eggs/nits and ectoparasites/lice may also be used. An ectoparasite/lice/nit comb (e.g., a microgrooved metal nit comb) might be used to make manual removal of ectoparasites and eggs easier. To be most effective at removing eggs, a comb may beneficially have multiple, closely spaced tines, or teeth, which will remove the ectoparasites/lice and eggs/nits as it passes through hair.
It is important that any comb that may be used to remove ectoparasites/lice and/or eggs/nits should be cleaned. Preferably, cleaning should occur between successive passings/combings through the hair and certainly between uses (e.g., between multiple uses on one person or between uses by different people), so that lice and nits are not spread inadvertently. Proper use of a comb to thoroughly remove an infestation may be a slow, methodical process, with each stroke taking careful measures not to contaminate others. The combing process could take many hours to properly comb out an infestation while continually cleaning the comb. A plurality of combs could possibly be used in one treatment in order to lessen the time consumption of cleaning the comb, involved therein, but this would require a large number of combs per client, each of which would need to be cleaned between clients.
In terms of cleaning a comb, merely wiping the comb on a towel or using a single string to clean in between each pair of tines of the comb would be very inefficient and time consuming and would require many passes or wipes in order to fully clean the comb. There is a need for systems, devices, etc. that allow for more quickly and efficiently cleaning combs and/or other tools/instruments used in conjunction with treating ectoparasite infestations (hereinafter, “lice tool,” though this term should not be considered as being limited to tools used only for lice, as tools/devices used for treating other ectoparasite infestations (e.g., fleas) on humans and animals are intended to be included), e.g., an ectoparasite, lice, flea, nit, and/or egg comb, so that all the ectoparasites, lice, fleas, eggs, and/or nits may be removed and cleaned off the lice tool with a minimum of effort.
This summary is meant to provide some examples and is not intended to be limiting of the scope of the invention in any way. The description herein relates to systems, methods, devices, apparatuses, instruments, tools, services, etc. that may be utilized for cleaning. Various features and steps as described elsewhere in this disclosure may be included in the examples summarized here.
Examples of embodiments of, and enhancements for, systems, devices/apparatuses, methods, etc. used for cleaning equipment, devices, apparatuses, instruments, tools, systems etc. are described herein. In one embodiment, the cleaning systems including one or more cleaning devices may be used for cleaning tools/instruments, e.g., tools used for ectoparasite infestations, head lice infestations, flea infestations, or the like.
In one embodiment a cleaning system including one or more cleaning devices and/or a cleaning device for cleaning a tool (e.g., a lice tool, comb, brush, other tool, etc.) may comprise a first portion (e.g., a lower portion) and a second portion (e.g., an upper portion) configured to engage the first portion. The cleaning system/device may include any of the features or components described or encompassed elsewhere in this disclosure. In one embodiment, the cleaning system/device may also include a cleaning surface (e.g., a first cleaning surface) configured for cleaning the tool (multiple cleaning surfaces are also possible), wherein the cleaning surface comprises at least one of bristles and strands (or both), and wherein the cleaning surface is configured to engage the tool. The second portion may include a first opening, and the cleaning surface may be configured to engage the tool when the tool is passed through the first opening. The second portion may also include a second opening, and a second cleaning surface (different from the first or other cleaning surface) may be configured to engage the tool when the tool is passed through the second opening. In one embodiment, the first opening and/or the second opening may be between 3 and 25 centimeters long and between 0.25 and 20 cm wide, between 5 and 15 centimeters wide and between 0.25 and 10 centimeters wide, or other lengths and widths.
In one embodiment, one or more openings (e.g., the first opening and/or the second opening) may be configured/sized to closely fit the tines of a lice comb therethrough (e.g., long and skinny like the cross section of a lice comb) or may be larger. The first cleaning surface may include multiple strands that extend across the first opening, and the multiple strands may be arranged parallel to each other or at angles to each other. The tool may be a lice comb, comb, brush, or other tool that includes multiple tines, and the multiple strands may be spaced relative to each other such that when the lice comb is inserted through the first opening, at least one strand of the multiple strands passes between each pair of tines of the multiple tines. In one embodiment, the multiple strands may be connected to a frame or cartridge that is enclosable between the first portion and the second portion. The cleaning system/device may include a fluid that contacts the cleaning surface. The fluid may be similar to other fluids/liquids described herein, e.g., it may comprise chemicals for killing ectoparasites. In one embodiment, the cleaning surface may be movable or rotatable in one or more dimensions, and this may be automated or manually done.
In one embodiment, the first portion may be hingedly attached to the second portion. The cleaning surface may be at least one of a brush and a comb. The first portion may be movable relative to the second portion from a first closed position to a second open position. In the second open position, the first portion may be angled between 10 and 90 degrees, 30 and 70 degrees, or a different angle relative to the second portion. The tool may be a lice tool, and the cleaning surface may be configured to engage the lice tool. The lower portion may be configured as a collection container that is able to collect materials dislodged from the tool during cleaning.
A method for cleaning a tool may comprise obtaining a cleaning system or cleaning device including a first cleaning surface comprising bristles, multiple strands extending across an opening, and/or any other features/components described elsewhere in this disclosure. The method may include drawing the tool (one or multiple times) across the first cleaning surface. With multiple strands, the tool may be drawn across the first cleaning surface such that multiple surfaces of the tool contact different strands of the multiple strands. The tool may be a lice tool with multiple tines, and drawing the tool across the first cleaning surface such that multiple surfaces of the tool contact different strands of the multiple strands may include drawing the lice tool across the first cleaning surface such that the different strands of the multiple strands pass between different pairs of tines of the multiple tines. The cleaning system/device may include a second cleaning surface comprising multiple bristles, multiple strands, etc., the method may include drawing the tool across the first cleaning surface and then drawing the tool across the second cleaning surface. This may include rotating, twisting, and/or pulling side to side the tool to cover and clean more surface area. At least one of the first cleaning surface and the second cleaning surface may further include a liquid thereon that may be similar to other fluids described herein (e.g., it may include chemicals for killing ectoparasites), and drawing the tool across the first cleaning surface or drawing the tool across the second cleaning surface may include bringing the tool into contact with the liquid. Other steps described elsewhere in this disclosure may also be used with various devices, components, features, etc.
The disclosed devices/apparatuses, systems, methods, etc. may be better understood with reference to the following drawings. The components in the drawings are not necessarily to scale.
While the present disclosure is subject to various modifications and alternative forms, specific embodiments thereof have been shown by way of example in the drawings and will herein be described in detail. Like references indicate similar elements. The invention should be understood to not be limited to the particular forms disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the present disclosure. It will be appreciated that the current illustrations are not limiting in their scope and that various features illustrated in different embodiments may be combined within a claimed embodiment.
The following description and accompanying figures, which describe and show certain embodiments, are made to demonstrate, in a non-limiting manner, possible configurations and steps of systems, devices/apparatuses, and methods for the cleaning of lice tools, including but not limited to nit combs, ectoparasite combs, flea combs, other devices, and the like. While the description herein, by way of example, is focused primarily on a description of cleaning tools for use in treating head lice infestations in humans, the systems, devices/apparatuses, methods, etc. described herein are not so limited and may be applied to tools for treating other types of insect/ectoparasite/other infestations (even if not involving lice). Further, while infestations of the head are primarily discussed herein, the systems, devices/apparatuses, methods, etc. described herein are not so limited and may be applied to infestations in areas other than a host's head (i.e., infestations in other treatment areas of an animal's body). Infestations that may be treated with the systems, devices/apparatuses, methods, etc. described herein may be on animal hosts (e.g., humans, dogs, other animals), or may be infestations in a variety of other locations. Further, while the description herein, by way of example, is focused primarily on a description of cleaning tools for use in treating infestations, the systems, devices/apparatuses, methods, etc. described herein are not so limited and may be applied to a variety of types of tools, e.g., the cleaning devices herein may be used for cleaning combs/brushes used by hair stylists, salons, or other companies/persons or for cleaning other types of tools that may for example, have multiple tines or something similar. Accordingly, the inventive principles associated with the embodiments described herein, may be applied to tools used for other embodiments and purposes, e.g., to clean tools used for other types of infestations or systems, devices/apparatuses, tools, methods, etc. used for other purposes.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure. However, the invention disclosed herein may be practiced without these specific details. In other instances, specific numeric references may be made, for example, to a “first” component, brush, etc. However, the specific numeric reference should not be interpreted as a literal sequential order but rather interpreted that, for example, the “first brush” is different from a “second brush,” unless otherwise indicated. Further, where various options within or between embodiments are presented, it will be understood that contemplated embodiments may include all permutations of these options. By way of a non-limiting example the phrase “at least one of bristles and strands” will be understood to include embodiments that have either, “bristles”, or “strands”, or both “bristles and strands”. Thus, the specific details set forth are merely exemplary. The specific details may be varied from and still be contemplated to be within the spirit and scope of the present disclosure. The term “coupled” is defined as meaning connected either directly to the component or indirectly to the component through another component. Further, as used herein, the terms “about,” “approximately,” or “substantially” for any numerical values or ranges indicate a suitable dimensional tolerance that allows the part or collection of components to function for its intended purpose as described herein.
For clarity it is to be understood that the word “proximal” refers to a direction relatively closer to a user using the device to be described herein, while the word “distal” refers to a direction relatively further from the user. For example, the end of a device closer to the body of a client is considered a distal end of the device, while the device end closer to the user is a proximal end of the device. Also, the words “including,” “has,” and “having,” as used herein, including the claims, shall have the same meaning as the word “comprising.”
According to various embodiments, the objectives described above and elsewhere herein may be accomplished by providing an improved system for cleaning tools used for ectoparasite infestations, including but not limited to nit combs. The present disclosure provides a system including a device for cleaning tools used for ectoparasite infestations, or “lice tools,” and a method associated with the system.

By way of a non-limiting example, the codes may disclose a specific type of brush with bristles that are capable of fitting between the tines of a specific type of nit comb. It will be appreciated that such logos, symbols, or alphanumeric codes may also be located on any portion of the cleaning device without departing from the spirit of the invention.
In an exemplary embodiment, each of the first and second portions 104, 108 may include one or multiple cleaning surfaces. The one or multiple cleaning surfaces may include brushes, bristles, sponges, wipes, etc. For example, a cleaning surface or two cleaning surfaces may include a first and second brush 124, 126. Each of the first and second brushes 124, 126 may include, for example, a multiplicity of bristles 128 aligned substantially parallel with one another and perpendicular to a surface of the first and second portions 104, 108. The bristles 128 may comprise individual strands of nylon, or similar material, of a size and shape that allow the bristles to fit between the tines of a nit comb. It will be appreciated that the bristles 128 may be made from other materials, aside from nylon, that possess different physical properties. It is also contemplated that each individual bristle may vary in properties such as strength, flexibility, stiffness, length, diameter, or cross-sectional shape so as to provide a cleaning surface best suited for different types of lice tools. The first and second brushes or if more brushes are used, may be formed in a variety of shapes and sizes and, while they may include bristles, may also or alternatively include other types of materials and surfaces, e.g., sponges, wipes, cloth, textured surfaces, and more.
In an exemplary method of use, the cleaning device 100, at rest, may be biased towards the second position, as best shown in
It is contemplated that the cleaning device 100 may include other forms of cleaning surfaces, such as pads, toweling, comb-like structures, others described herein, or combinations thereof. In an exemplary embodiment, the cleaning surface may include a comb-like structure, (not shown). The comb-like structures may be positioned similarly to the first and second brushes 124, 126 and may consist substantially of a row of tines. By way of a non-limiting example, the tines may be sized and spaced so that they are capable of fitting between the tines of a nit comb. The tines of the comb-like structure may be made of nylon or similar material that may possess suitable physical properties in rigidity, strength, flexibility, or the like. It is contemplated that each cleaning surface on the first and second portions 104, 108 may include different forms, by way of a non-limiting example, a comb-like structure may be disposed on the first portion while a second brush 126 may be disposed on the second portion 108. Similarly a comb-like structure may be disposed on a first portion 104 while a pad or toweling may be disposed on a second portion 108. It will be appreciated that other combinations of cleaning surfaces are contemplated without departing from the spirit of the invention.
In an exemplary embodiment the cleaning surface of the cleaning device 100 may include a multiplicity of strands where one end of each of the strands is attached to the first portion 104 and the other end of each of the strands is attached to the second portion 108.

In an exemplary embodiment, the strands 312 may comprise of nylon, polypropylene, polyamide, polyester, silk, steel, polytetrafluoroethylene, although other materials that display suitable physical properties are also contemplated. The strands 312 may be configured in a similar way to those described in other exemplary embodiments herein. The frame 208 may be configured to fit with the upper portion 306 so that the strands 312 cover at least one or both of the first and second openings 324, 326. In an exemplary embodiment the frame 208 may be disposed between the upper portion 306 and the base portion 304. In an exemplary embodiment, at least one or both of the upper portion 306 or base portion 304 may include a rim 214 or edge that abuts against a portion of the frame. In an exemplary embodiment, the frame 208 includes at least one or multiple posts 216, which may be similar to posts described elsewhere herein. The post(s) 216 may be configured to dispose within a housing 218 disposed on at least one or both of the upper portion 306 or base portion 304. I will be appreciated that the configuration of rims 214, edges and posts 216 may vary between the frame 208, upper portion 306 or base portion 304 without departing from the spirit of the invention.
In an exemplary embodiment, the upper portion 306 may also include a first portion 330 and a second portion 332 that extend downwards, substantially perpendicular from the upper portion 306. Each of the first and second portions 330, 332 may include one or more cleaning surfaces.
