[0003] Chemical injury, eye, lavage, water bottle, on the go, IV tubingIntroduction

[0004] Eye injuries are common in warfare. Chemical burns to the eye are among the most urgent of ocular emergencies and the extent of ocular damage and visual impairment are minimized with rapid initiation of irrigation. Ocular irrigation is a well-known procedure for treatment of eyes that are traumatized or otherwise have medical ailments. However, effective ocular irrigation options are often not available in resource-constrained environments. An ocular lens, as disclosed in U.S. Patent No. 3,664,340 (“the ’340 patent”) is a commonly used irrigation device that provides continuous lavage to the cornea by directing fluid to contactlens like inserts which rest on the eyes. The ocular lens of the ’340 patent may be used for emergency ocular irrigations using fluid delivered from any disposable water bottle. The widespread availability of disposable water bottles, even in resource-constrained environments, and the small size of the disclosed adaptor and the ocular lens of the ’340 patent will allow effective ocular irrigation in austere environments at or near the point of injury.While the standard of care in hospital settings uses specialized irrigation fluids, bottled water is a suitable alternative in emergency situations.

[0005] Rapid prototyping and design iteration of the novel device was enabled through the use of Additive Manufacturing (3D printing). 3D printing has enabled point of need fabrication using a variety of materials and has allowed for the rapid deployment and implementation of solutions in austere operating environments. The disclosed adapter is an example of a novel solution to a clinical problem enabled by 3D printing coupled with the combined expertise of clinicians and design engineers. These additive manufacturing solutions can be used to develop devices to overcome the specific challenges faced by service members in battlefield environments.

[0006] The ocular lens of the ’340 patent, however, is limited to use with availability of IV bags and can be difficult to employ in resource-constrained, austere, or mass casualty environments where insufficient amounts of resources exist. This disclosure introduces a universal adaptor that facilitates emergency ocular irrigation in austere environments.SUMMARY OF THE DISCLOSURE

[0007] In a first aspect of the disclosure, an exemplary adaptor may include a resilient, frustoconical body configured to be at least partially inserted into an opening at one end of a bottle while forming a seal with an inner peripheral surface of the opening. The body may define first and second passageways extending through the body from an upper surface of the body to a lower surface of the body. The first passageway may have a generally square-shaped cross-section along at least a portion of the length of the first passageway. The second passageway may have a generally circular-shaped cross-section along at least a portion of the length of the second passageway.

[0008] In a second aspect of the disclosure, a method for irrigation of an eye may include inserting a body of an adaptor into an open end of a bottle. The adaptor may include a resilient, frustoconical body configured to be at least partially inserted into the open end of the bottle while forming a seal with an inner peripheral surface of the open end of the bottle.

[0019] Outside of the hospital, availability of IV bags to enable ideal long-duration, steady lavage of a wound or eye is basically non-existent for practical reasons. Water bottles, however, are ubiquitous. Although non-sterile, these sources are ideal when connected to IV tubing to provide slow steady lavage. An adaptor according to various embodiments described in this disclosure may enable the use of water bottles in place of IV bags for the containment of liquids used during lavage of a wound or an eye.

[0020] In an exemplary method according to various embodiments of this disclosure, the cap may be removed from a typical water bottle, and an adaptor according to various embodiments of this disclosure may be inserted into the open end of the bottle to seal the bottle. An exemplary embodiment of the adaptor may accommodate a venting conduit that extends through a first passageway penetrating through the adaptor and that protrudes into the bottle to allow for equalization of atmospheric air pressure as liquid flows from the bottle,thus enabling the steady flow of the liquid from the bottle. An exemplary embodiment of the adaptor may also accommodate IV tubing that extends at least part way into a second passageway penetrating through the adaptor. Liquid, including various pharmaceutical solutions contained within the bottle, may flow smoothly from the bottle and through the IV tubing to an application area on a patient. Water bottle tops may have many different threaded configurations such that a large variety of different threaded bottle caps would be needed to properly cap a bottle. The disclosed adaptor may be composed of a resilient material and may be tapered such that a single exemplary configuration of the adaptor may be used to seal closed different openings in a large variety of different water bottles, and provide a stable connection for venting conduit and / or tubing that allows for the dispensing of liquid from the bottles. Various disclosed embodiments of the adaptor according to this disclosure may be configured to accommodate a venting conduit that penetrates through the adaptor and extends into the bottle for the purpose of equalizing atmospheric air pressure to allow for smooth dispensation of liquid from the bottle. Embodiments of the adaptor may also accommodate IV tubing that may be inserted at least part way into a passageway extending through the adaptor for enabling the flow of liquid from the bottle. The passageways through the adaptor for accommodating a venting conduit and the IV tubing may be provided with different cross-sectional configurations and dimensions, depending on a variety of different factors that may include the viscosity or other characteristics of a liquid to be dispensed from the bottle, a desired rate of flow of the liquid from the bottle, temperatures and other environmental considerations where the adaptor is to be used, and manufacturability considerations, such as the ease in producing the adaptor using additive manufacturing techniques such as 3D printing.

[0021] In an exemplary embodiment of this disclosure, the adaptor may include a resilient, frustoconical body configured to be at least partially inserted into an open end of a bottlewhile forming a seal with an inner peripheral surface of the opening into the bottle. The body of the adaptor may define first and second passageways extending through the body. The first passageway may have a respective opening in each of an upper surface of the body and a lower surface of the body at opposite ends of the first passageway, and a generally square- shaped cross-section along at least a portion of the length of the first passageway. The second passageway may have a respective opening in each of the upper surface of the body and the lower surface of the body at opposite ends of the second passageway, and a generally circular-shaped cross-section along at least a portion of the length of the second passageway.

[0022] In some embodiments, the adaptor may be frustoconical in shape, and one or both of the first passageway and the second passageway may be tapered along the length of the adaptor such that the respective openings at opposite ends of one or both of the passageways may have different dimensions.

[0023] As shown in Figs. 1A and IB, an exemplary disclosed adaptor 100 may include a body 102 and two faces 104, 106 at opposite ends of the body 102, with each face including a circular orifice 108 and a square or rectangular orifice 110.

[0024] As shown in Fig. 2, an exemplary disclosed adaptor 200 may include a passageway 202 with a circular cross-section penetrating through the length of the adaptor body 204 from a first face 206 of the adaptor 200 to a second face 208 at an opposite end of the adaptor body 204. The passageway 202 may terminate in a circular orifice 210 at the first face 206 and a separate, circular orifice 212 at the second face 208. The exemplary adaptor 200 may additionally include a passageway 214 with a square or rectangular cross-section penetrating through the length of the adaptor body 204 and terminating in a square or rectangular orifice 216 on the first face 206 of the adaptor 200 and a separate, square or rectangular orifice 218 on its second face 208. The dimensions of the orifices at the opposite ends of each of thepassageways 202, 214 may be the same in embodiments wherein each of the passageways has the same cross-sectional area along its length. Alternatively, the dimensions of the orifices at the opposite ends of each of the passageways may be differ from one another when the passageways are tapered along their lengths, or when the openings into the passageways are chamfered, flared, or otherwise configured.

[0025] In other embodiments, the adaptor body may be shaped and configured differently. For example, the adaptor body may be tapered, cone-shaped, or truncated, or some combination thereof. In some embodiments, the adaptor body may define more than two passageways extending through the body, such as, for example, three, four, or five passageways. In some embodiments, the first passageway may be configured or shaped differently. For example, the first passageway may be circular-shaped or triangular-shaped. In some embodiments, the second passageway may be configured or shaped differently. For example, the second passageway may be square-shaped or triangular- shaped.

[0029] In some embodiments, the system may comprise a bottle. The bottle may contain a liquid used for ocular irrigation for treatment of an eye. In alternative embodiments, the bottle may be employed for any other purpose. In some embodiments, the venting conduit may extend through the above-disclosed first passageway and protrude into the bottle such that an end of the venting conduit is proximate to a closed end of the bottle opposite from the open end of the bottle. The venting conduit enables equalization of atmospheric air pressure as liquid is dispensed from the bottle, thus preventing a vacuum from forming at the bottom of the bottle when liquid is discharged from the bottle. The venting conduit may penetrate through the adaptor according to various embodiments of this disclosure and extend into the bottle to a point near the closed bottom of the bottle in order to allow external atmospheric air to be sent directly to the bottom of the bottle as the liquid begins to flow from the bottle.

[0042] In some embodiments, the above-disclosed method may comprise inserting an adaptor into an open end of a bottle, wherein the adaptor comprises a resilient, frustoconical body configured to be at least partially inserted into an open end of a bottle while forming a seal with a surface of the bottle but wherein the adaptor body either does not define first and second passageways or, alternatively, defines first and second passageways of different shapes and configurations than disclosed above.Methods

[0043] A universal adapter to facilitate emergency ocular irrigation in austere environments using the ocular lens of the ’340 patent as an emergency eye irrigation device was developed through collaboration between an optometrist and a physician at the USU School of Medicine and engineers at the USU 4D Bio3Center for Biotechnology. The adapter between the IV tubing of the ocular lens of the ’ 340 patent and a disposable water bottle was designed to be small, inexpensive, provide a leak-free connection to the IV tubing sheath, and provide a universal fit to all disposable water bottles.

[0044] An initial design iteration included a screwcap adapter for a standard water bottle using Computer Aided Design (CAD) software that was 3D printed on a FormLabs Form3B resin printer using biocompatible BioMed Clear resin. Because of inconsistent screwcap threads across different water bottle brands, the screwcap design was replaced with an internal stopper design, inspired by an Erlenmeyer flask stopper. The design includes an orifice for insertion ofthe IV spike that attaches the liquid reservoir to tubing. It was printed on an Ultimaker S5 printer that has been previously deployed in an austere Arctic environment. A third and final iteration was developed to include a 3D printed venting conduit to allow liquid to flow out of the bottle at a sufficient flow rate and was also printed on the Ultimaker S5.

[0045] Testing was completed to determine the fit of the adapter with bottles of various sizes, shape, and volume. Liquid flowrate from the water bottle was tested to ensure appropriate delivery of irrigating solution to the eye.Results

[0046] The initial screwcap design did not provide a universal adapter because of slight differences in cap thread design and dimensions between disposable water bottles. Additionally, the hard resin resulted in a brittle part that could be broken when carried in a battlefield medical first aid kit.

[0047] The internal stopper design provided a watertight fit across a range of bottle types. The material selected to print the stopper adapter was a thermoplastic polyurethane (Ultimaker TPU 95A) that provided both rigidity for insertion and flexibility for secure insertion and liquid seal. The initial stopper design did not allow air to enter into the bottle to replace water flowing into the IV tubing and ocular lens of the ’340 patent. This caused water to quickly cease flowing into the IV tube once a vacuum had built up inside the water bottle. Therefore, a venting conduit was added to the design to allow for air displacement of the liquid in the water bottle. With the addition of the venting conduit, water flowed continuously into the IV tubing and was only limited by the IV tubing’s flow regulator. The rigid venting conduit was printed using inexpensive polyethylene terephthalate glycol (PETG), although many other materials could have been used. The materials used in this design iteration are durable and the stopper design allows for accommodation of a wide variety of bottle types and sizes that may be present inresource constrained environments. This universal water bottle adapter device allows for leveraging supplies already carried by service members to reduce the weight and burden on deploying troops. The universal water bottle adapter device can be printed in less than 1 hour. The CAD files are available in an easily accessible format and can be printed prior to deployment or using an onsite printer.

[0048] In some embodiments, a step-wise use of the adaptor is discussed below:• Step 1 : A venting conduit may include frangible portions spaced apart from one another and can be adjusted to match the length of the water bottle.• Step 2: The venting conduit may be inserted into the adaptor, along with the IV tubing spike of the ocular lens of the ’ 340 patent. The adaptor may then be secured in the opening of the water bottle.• Step 3: The water bottle may then be inverted and a controllable valve opened to allow water to flow through the ocular lens.• Step 4: The ocular lens may be inserted and irrigation / lavage commenced.

[0049] In some embodiments, the venting conduit may be snappable to accommodate various bottle sizes. Frangible portions spaced apart from one another may allow for the venting conduit to be easily snapped at various locations, and the location of the frangible portions may be determined by the length of various common bottles. The venting conduit may be adjustable to accommodate various bottle sizes or, alternatively, may be pushed in a variable amount to accommodate any water bottle size.

[0050] In some embodiments, the disclosed adaptor may be employed for delivery of luminescent anesthesia. In particular, lidocaine (0.05-0.10%) may be dissolved in a water bottle and salts (i.e., sodium chloride) added to obtain an isotonic solution. An antibiotic (i.e., 0.9- 1.1% benzyl alcohol) may be included as an antibiotic preservative in bacteriostatic water toensure sterility of water. The water bottle may be connected to the disclosed adaptor along with IV tubing and infusion commenced.

[0051] In some embodiments, the disclosed adaptor may be employed for delivery of water- soluble drugs intravenously. In particular, drug may be dissolved in a water bottle and salts (i.e., sodium chloride) added to obtain an isotonic solution. Examples of potential drugs for dissolution include sargramostim, anticibrinoylic agents (e.g., aminocaproic acid, tranexamic acid), analgesics (e.g., ketamine, acetaminophen, fentanyl), and antibotics, such as cefalozin, clindamycin phosphate, and ceftobiprole medocaril. An antibiotic (i.e., 0.9-1.1% benzyl alcohol) may be included as an antibiotic preservative in bacteriostatic water to ensure sterility of water. The water bottle may be connected to the disclosed adaptor along with IV tubing and infusion commenced.

[0052] In some embodiments, the disclosed adaptor may be employed for hemorragic shock treatment. In particular, the disclosed adaptor may be employed for delivery of fluids intravenously to replace lost blood volume. In particular, salts (e.g., sodium chloride, Ringer’s lactate) may be added to create an isotonic solution. An antibiotic (i.e., 0.9 % benzyl alcohol) may be included as an antibiotic preservative in bacteriostatic water to ensure sterility of water. The water bottle may be connected to the disclosed adaptor along with IV tubing and infusion commenced.

[0053] Other potential applications of the disclosed adaptor include reconstitution of a lyophilized plasma, rehydration of food, connecting water bottles to water filters for emergencies, or other eye lavage techniques.Conclusion

[0054] A universal water bottle adapter was developed as a cost effective and user-friendly option for rapid initiation of irrigation to injured eyes in a battlefield setting. The design allows for a watertight seal, easy insertion of the IV spike included in an emergency eye wash kit, and intuitive use for a hands-free eye irrigation in the critical window following ocular injury. The CAD files developed can be transferred and used to rapidly 3D print this device at or near the point of need. Implementation of the water bottle adapter will be field tested during an Ocular Trauma course offered at USU.
