Abstract
Description
- This claims priority to U.S. Provisional Patent Application No. 61/595,635 filed on Feb. 6, 2012 entitled “Antiseptic Applicators and Protective Devices,” which is hereby incorporated by reference in its entirety.
- Healthcare acquired infection (HAI) has been recognized as a significant cause of preventable mortality and morbidity. In the United States, HAI annually costs nearly 99,000 lives and billions of dollars in additional treatment and hospitalization. Klevens, et al., Estimating Health Care-Associated Infection and Deaths in U.S. Hospitals, 2002, Public Health Reports, Vol. 122, p. 160, 2007. Contamination of intravascular catheters, surgical sites and invasive procedure sites, frequently leads to device removal and replacement, prolonged parenteral antimicrobial therapy, and extended hospitalizations and rehabilitation.
- The spread of multi-antimicrobial resistant organisms frequently are spread by healthcare providers' hands or medical equipment, from one colonized or infected patient to other susceptible patients. Surgical site infections may result from inadequate antiseptic preparations of the skin. Widespread use of chlorhexidine gluconate (CHG) for routine washing and wiping of pre-operative sites, has led to the increased incidence of resistant Staphyloccus aureus, both to methicillin (MRSA) and CHG, in some hospital environments.
- The detailed description is set forth with reference to the accompanying figures. In the figures, the left-most digit(s) of a reference number identifies the figure in which the reference number first appears. The use of the same reference numbers in different figures indicates similar or identical items or features.
-
FIG. 1 illustrates an example portable medical device protector having a permeable applicator located within an impermeable container. -
FIG. 2 illustrates another example portable medical device protector having a removable tray for storing one or more permeable applicators within an impermeable container. -
FIG. 3 illustrates another example portable medical device protector having a removable tray storing a permeable applicator for scrubbing a device (illustrated as a stethoscope) and an impermeable container for securing and preventing recontamination. -
FIG. 4 is a flow diagram showing an example process for operating an example portable medical device protector. - This disclosure describes medical applicators and protectors designed to reduce and/or prevent infections. In one embodiment, the disclosure describes a portable medical device protector comprising a sealable impermeable container or receptacle to hold a portable medical device (e.g., stethoscope) and a permeable, absorbent and/or adsorbent applicator carrying an antimicrobial or antiseptic composition. In some embodiments the antimicrobial composition may comprise water, a low molecular weight alcohol, a peroxide or peroxide-generating agent, and a chelating agent. In some embodiments, the permeable applicator may be used to wipe the portable medical device to prevent and/or reduce transmission of infection as the portable medical device is used or transported between multiple patients.
- The detailed discussion below begins with a section entitled “Example Antimicrobial Composition”, which describes in detail an example antimicrobial composition that may be included in the medical applicators and protectors described herein. The next section entitled “Example Device Protectors” describes example cleaning and protective devices for use of a portable medical device. Next, an “Example Process” for operating an example device protector is described. Finally, the disclosure concludes with a brief “Conclusion.”
- This overview, including section titles, is provided to introduce a selection of concepts in a simplified form that are further described below. The overview is provided for the reader's convenience and is not intended to limit the scope of the claims, nor the proceeding sections.
- In one example implementation, antimicrobial compositions that may be used in connection with the approaches described herein may include those described in, for example, International Patent Application No. PCT/US2011/022150, filed Jan. 21, 2011, to Tennican et al., and, U.S. Non-Provisional patent application Ser. No. 13/688,078, filed Nov. 28, 2012, to Tennican, which are incorporated herein by reference. For example, the antimicrobial compositions may include water (H2O), a strong and non-toxic chelating agent such as ethylenediaminetetraacetic acid (EDTA) (e.g., disodium EDTA, calcium disodium EDTA, magnesium EDTA, potassium EDTA, gallium EDTA) or sodium citrate (or acids, salts, derivatives, or other forms of EDTA or sodium citrate), a short-chain monohydric alcohol (e.g., ethanol with a molecular formula of C2H5OH and an empirical formula of C2H6O), and a strong, small molecule oxidizing agent such as hydrogen peroxide (H2O2). In one specific example, the compositions may consist essentially of water, EDTA, ethanol, and hydrogen peroxide. Additional ingredients can include thickeners, gellants, surfactants, foamers and/or foam stabilizers. However, in other examples, other antimicrobial compositions may be used in combination with the applicators and devices described in this disclosure.
- The antimicrobial compositions may be in a liquid form or a gel form, and may be combined with one or more carriers or diluents, depending on the needs of a specific application. For example, if the antimicrobial composition is used as a cleaning agent the antimicrobial composition may be in a liquid form. In that case, the concentration of the various constituents may depend on, for example, a desired level of sanitation and/or disinfection, whether the composition is being applied directly to living tissue or to a medical device, and/or to avoid irritation of tissue to which the composition will be applied directly or indirectly (e.g., via a medical device to which the composition is or was applied).
- In addition to providing disinfection at the time of the application, the antimicrobial compositions may also provide a lasting barrier against contamination. For example, even after volatile constituents of the composition (e.g., water, alcohol, hydrogen peroxide, etc.) have evaporated, the chelating agent may remain on the treated surfaces (e.g., multiple use vial or port cleaning/protecting device, stethoscope, fingers, surrounding tissue, etc.) as a barrier that will provide antibacterial, antifungal or sporicidal (e.g., preventing germination of the spores), anti-parasitic, spermicidal or spermiostatic (e.g., decrease the motility of spermatozoon) and antiviral qualities. By robbing the environment of components (e.g., iron, magnesium, and manganese) that are needed for the bacteria (e.g., staphylococcus aureus (MRSA), Pseudimonas aeruginosa and other resistant bacteria), spores, parasites, fungus, and viruses to reproduce, the chelating agent provides a lasting defense to contamination even after other constituents of the antimicrobial composition have evaporated. Furthermore, the hydrogen peroxide in the antimicrobial compositions may induce a charge on a surface of materials (e.g., silicone materials) to which the antimicrobial compositions are applied, which make the materials more resistant to bacteria or other microorganisms.
- The antimicrobial composition described above may also provide a visual indication of contamination when applied to a surface or material, such indication may allow users to identify and clean surfaces to prevent infection.
- The term “about” or “approximate” as used in context of describing the example antimicrobial composition is to be construed to include a reasonable margin of error that would be acceptable and/or known in the art.
- Various example protective devices are described herein. Described generally with reference to
FIGS. 1-3 are example device protectors configured to prevent and/or reduce transmission of pathogenic organisms from one colonized patient, surface or user to another patient, surface or user. -
FIG. 1 illustrates anexample device protector 100 for use on a portable medical device. An example portable medical device include, but are not limited to, a stethoscope, a thermometer, a blood pressure monitor, a pulse oximeter, a nebulizer and associated equipment, a scope, a blood glucose monitor, a doppler, a capnograph, a suction pump, various equipment mouthpieces, diagnostic or therapeutic ultrasonic transducers and/or other diagnostic equipment. In one embodiment, anexample device protector 100 may be configured to house any section of or an entire portable medical device and act as a protective cover. As illustrated inFIG. 1 , thedevice protector 100 may contain animpermeable container 102 to house any section of or an entire portable medical device. Theimpermeable container 102 may be configured in any number of sizes designed to enclose any section or an entire portable medical device. For example, theimpermeable container 102 may be configured to house the “bell” of a stethoscope or configured to house the entire stethoscope. Example materials for the composition of the impermeable container include, but are not limited to, polyethylene, aluminum oxide, aluminum foil, silicon oxide coated polymeric films, polypropylene, polysilicone, polytetrafluoroethylene, polyvinyl chloride, mylar, or combinations thereof. - In some embodiments,
impermeable container 102 may include aclosure mechanism 104 at theopening end 106 of thecontainer 102 configured to securely enclose an inserted portion of the portable medical device. Example enclosure mechanisms may include, but are not limited to, a draw string, zip lock, foam opening, twist tie, plastic clip and/or a spring material. - In some embodiments, the closure mechanism is a draw string and/or twist tie. In these embodiments, the opening of the impermeable container may comprise a string, wire or other like material which has two ends extending from the impermeable container. The contents of the impermeable container (e.g., bell of the stethoscope) are enclosed when the ends of the string are pulled and/or twisted. Thus, closing the opening of the impermeable container.
- In another embodiment, the closure mechanism on the impermeable container may be a foam opening. The foam opening may be configured to allow the portable medical device, or any part of thereof, to be inserted through the opening. Upon receipt of the portable medical device, the foam opening may revert back to its unopened position thereby protecting the portable medical device from contaminants located outside the impermeable container.
- In another embodiment, the closure mechanism comprises a spring material. The spring material may hold the opening of the impermeable container in the closed position. The user may squeeze the opposing ends of the closure mechanism to activate the spring causing the opening of the impermeable container to open and become accessible to insertion of any portion of the portable medical device.
- In some embodiments, a
permeable applicator 108 may be stored within theimpermeable container 102. Thepermeable applicator 108 may be impregnated or coated with an antimicrobial or antiseptic composition, such as the antimicrobial composition described in the preceding section. In some embodiments, thepermeable applicator 108 may be removable from theimpermeable container 102 and may be used to clean and/or disinfect any portion of the portable medical device (e.g., diaphragm, chestpiece, tubing, eartips, or any other part of a stethoscope). -
Permeable applicator 108 may be configured in various shapes and size. For example, as illustrated inFIG. 1 , applicator may be smaller than the impermeable container. In other embodiments, the applicator may be substantially the same size or larger than the impermeable container. In some embodiments, the applicator may be folded, doubled, tripled, etc. upon itself in any suitable manner to allow the applicator to fit within the impermeable container. - In another embodiment, the
permeable applicator 108 may be attached as the interior lining of theimpermeable container 102. For example, the permeable applicator may be removably or irremovably attached to the interior walls of the impermeable container. In this embodiment, a user may place the portable medical device, or any portion thereof, within the impermeable container. Once the device is inside the container, the user may manipulate the container by, for example, using a massaging action. Such action may allow the permeable applicator attached to the interior walls of the container to scrub/disinfect the medical device with the antimicrobial composition. - Example materials for the composition of the
permeable applicator 108 include, but are not limited to, starch polymer, cellulosic gel, polyethylene foam, silicone open-cell foam, or mixtures thereof. In some embodiments, thepermeable applicator 108 may include different surface treatments (e.g., siping, slitting, etc.), surface finishes (e.g., macro-, micro-, or nano-structures, etc.), and/or contours (e.g., rounded, ribbed, protrusions, fingers, etc.) to allow a user to grip the applicator and aid in scrubbing or cleaning the medical device. -
FIG. 2 illustrates an alternative embodiment of adevice protector 200, where one or more permeable applicator(s) 202 may be stored on aremovable tray 204 that is located within theimpermeable container 102. Thetray 204 may be sealed within theimpermeable container 102 prior to use by the user. In some embodiments, thetray 204 may be removed once theimpermeable container 102 is opened allowing the user to access/use the one ormore applicators 202.Tray 204 may be discarded prior to the placement of any part of the medical device within theimpermeable container 102. - The one or
more applicators 202 may have any of the features described above with regard to the permeable applicators ofFIG. 1 . In some embodiments, each of the one or more applicators on the tray may contain the same or different cleansing, antiseptic, or antimicrobial agent, or various concentrations thereof. -
FIG. 2 illustrates an example drawstring closure mechanism 206 as described above with reference toFIG. 1 . However, in other embodiments, any of the other closure mechanism described above with reference toFIG. 1 may be used with thedevice protector 200. - Example materials for the composition of the
tray 204 include, but are not limited to, polypropylene, high-density polyethylene, polytetrafluoroethylene, polyvinyl chloride, or any other suitable thermoplastic polymer. In some embodiments,tray 204 may be configured having one or more dividers to separate each portion storing the one or more permeable applicator(s) 202. -
FIG. 3 illiterates yet another embodiment of a device protector. In this embodiment, animpermeable container 300 and apermeable applicator 302 may be located within a sterile,discardable package 304. As shown inFIG. 3 , the impermeable container 300 (shown on bothtray 204 and on thebell 306 of stethoscope 308) and thepermeable applicator 302 may be located ontray 204 within thesterile packaging 304. Upon opening of thesterile package 304, the user may removetray 204 and use thepermeable applicator 302 that is impregnated with an antimicrobial or antiseptic composition to disinfect any part of the portable medical device, such as thestethoscope 308 illustrated inFIG. 3 . After disinfecting the portable medical device with the applicator, the user may then place the portable medical device, or any portion thereof, within theimpermeable container 300 to protect it from contamination. For example, as illustrated inFIG. 3 , theimpermeable container 300 would protect thebell 306 of thestethoscope 308 from coming into contact with one or contaminates when the user places the bell in a pocket, bag, or the like. - In some embodiments, the applicator located within the impermeable container or on a tray in the sterile package may be an applicator having an impermeable layer attached to a permeable, absorbent and/or adsorbent bottom layer thus, preventing an existing infectious agent on the user hand from transferring to the permeable bottom layer and the portable medical device.
