This application relates generally to bodily fluid removal during an aircraft flight. More specifically, this application describes a device, system, and method of use thereof to aid a female pilot in voiding bodily fluid in a confined condition, such as in-flight.
Nature can call at inopportune moments. For example, nature can call mid-flight for a pilot. A pilot, particularly, a female pilot, confronted with the need to void her bladder mid-flight faces a difficult decision. Does she void her bladder into a diaper that pilots often wear during long flights? In doing so, she will endure an uncomfortable rest of her flight as well as risk tissue maceration from prolonged exposure to moisture. Or does she try to hold it and risk a urinary tract infection? Neither choice is appealing. Moreover, the inconvenience and messiness of voiding mid-flight can cause some pilots to dehydrate with accompanying negative impacts on energy, cognition, and judgement. Thus, it would be desirable to provide a female pilot with a more desirable alternative option for voiding her bladder mid-flight. Specifically, it would be desirable to provide an alternative device, system, and/or method that avoids or minimizes known issues with existing mid-flight bladder voiding options.
In accordance with embodiments of the invention, aspects of a micturition device, system, and a corresponding method for use thereof are described. Aspects of a micturition device, system, and a corresponding method for use thereof help to avoid the problems associated with existing devices, systems, and methods.

The steps and elements described herein as part of various embodiments and aspects can be reconfigured and combined in different combinations to achieve the technical effects as may be desired. To this end, the embodiments and aspects can be combined in any combination or sub-combination.
Various additional features and advantages of the invention will become more apparent to those of ordinary skill in the art upon review of the following detailed description of one or more illustrative embodiments taken in conjunction with the accompanying drawings. The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate one or more embodiments of the invention and, together with the general description given above and the detailed description given below, serve to explain the one or more embodiments of the invention.
As set forth in greater detail below, the system 10 includes a micturition device 12 connected to one or more receptacles 16 for receiving fluid from the micturition cup 14. A series of tubes (e.g., disposable tube 18 and vacuum tube 20) connect the micturition cup 14 to the receptacle 16. The disposable tube 18 connects to the device 12 via a connector 19 (e.g., snap fit). The vacuum tube 20 may be a multi-lumen tube wherein the number of lumens corresponds to the number of receptacles 16. The receptacle may be one or more 2000 mL collection bags with high burst strength. Smaller collection bags (e.g., 500 mL or 1000 mL) could be substituted. The receptacles 16, in one embodiment, are disposable. The receptacles 16 may include a material (e.g., moisture absorbent granules) within the receptacle 16 that causes fluids to solidify, semi-solidify, or gel once they contact the material. The addition of such a material would help to reduce mess or minimize the chance for aircraft instrumentation shortage that could be caused by accidental breakage of the receptacles 16.
With continued reference to
Both the disposable tube 18 and the vacuum tube 20 connect to the pressure controller 24. The disposable tube 18 connects to the pressure controller 24 by a snap-lock sealed valve on a distal end (e.g., away from the device 12) of the disposable tube 18. The pressure controller 24 may be a dial controller and have a number of settings. For example, the pressure controller 24 can have two settings-on and off. Alternatively, the pressure controller 24 can have three settings-off, on (low), and on (high). “Low” and “high” are understood to mean relative amounts of negative pressure generated by the vacuum source 22 for drawing fluid through the tubes 18, 20. The pressure controller 24 may be set to “high” when a user is purposefully emptying her bladder, for example. The pressure controller 24 may be set to “low” to remove small amounts of excess moisture (e.g., between voidings). Removing excess moisture on the “low” setting helps to keep the vaginal area dry and helps to minimize possible tissue maceration from caustic urine over long flights. Such a setting would also be helpful for managing the unpredictability of menstrual flow. Still further, the low setting may also provide reinforcement for the rim gasket or seal 32 to be used on the cup rim to add further protection against leakage. The pressure controller 24 may be secured, by Velcro or similar, to a strap on user's thigh. Alternative locations for the pressure controller 24 are contemplated. The pressure controller 24 strapped to a user's thigh allows for one-handed control of micturition while in flight, for example.
With continued reference to
The features of the system 10 are set forth in further detail below to clarify each of the functional advantages and other benefits provided in this disclosure. Other advantages and technical effects of the embodiments of this invention will become evident to one skilled in the art from the following description.
The micturition cup 14 includes an outlet port 34. In the depicted embodiment, the outlet port 34 is located on the cup floor 28. The outlet port 34 provides a path for a fluid (e.g., urine, menstrual flow) in the micturition cup 14 to exit the cup 14. The cup floor 28 is contoured to direct the flow of a fluid in the cup 14 towards the outlet port 34 to encourage the fluid to leave the cup 14. In one embodiment of the invention, an interior of the cup 14 may be coated with a coating. The coating may be a hydrophobic coating material to prevent a fluid (e.g., urine) from sticking to the cup 14 and to further encourage fluid to flow to the outlet port 34. Alternatively, the coating could be an anti-coagulant coating material to prevent a fluid (e.g., menstrual flow) from sticking to or accumulating within the cup 14. For example, a heparin coating may be used. Alternative coating materials are also contemplated.
The micturition cup 14, as depicted in
Each end of the slide fitting 38 includes an orifice 40. The orifices 40 are connected by a passage 42. The passage 42 is configured to allow a fluid (e.g., urine, menstrual flow) to flow through the passage 42. The fitting 38 also includes channels 44 between an opposite end of the fitting 38 and a surface of the slide plate 36. The channels 44 are configured to interact with another aspect of the micturition system 10, as described in greater detail below. As illustrated by arrow A2, the cup 14 and the slide plate 36 are configured to engage with one another, as described in greater detail below with respect to
In one embodiment, the slide plate is a separate piece from the cup. It is then joined in use of the system. For example,
In an alternative embodiment, as shown best in
Further, as illustrated by arrow A3, the fitting 38 is adjustable (e.g., slides) with respect to the track 48. Sliding the fitting 38 along the track 48 allows a user (wearer) to move the micturition device 12-particularly, the micturition cup 14. The position of the cup 14 can be adjusted along the length of track 48 for user comfort as well as to ensure that the cup 14 is properly placed in the vaginal area to capture fluids (e.g., urine, menstrual flow). Further, adjusting the position of the cup 14 ensures that the device 12 is more compatible with a user's body, the particular position of the user's body within a seat, for example, and helps to minimize pulling or strain on the disposable tube 18, for example.
For coupling the cup and fitting 30 to garment 46, the track 48 may be spread apart, due to the flexibility of the fabric, to allow the fitting to pass through or over the track and then engage the track with the cup on opposite sides as shown in
While the present invention has been illustrated by the description of various embodiments thereof, and while the embodiments have been described in considerable detail, it is not intended to restrict or in any way limit the scope of the appended claims to such detail. The various features discussed herein may be used alone or in any combination. For example, though the system 10 is described above for use by a female pilot, the system 10 could be adapted to the male anatomy to provide a less-invasive replacement for a catheter. Additionally, the described system 10 could be used in an environment other than a cockpit-in a hospital or home use, for example. Additional advantages and modifications will readily appear to those skilled in the art. The invention in its broader aspects is therefore not limited to the specific details and illustrative examples shown and described. Accordingly, departures may be made from such details without departing from the scope of the general inventive concept.
