Description

PA TENT COOPERAT ION TREATY (PCT) PATENT APPLICATION INTELLIGENT FLUID MONITORING CUP SYSTEM FOR HEALTHCARE SETTINGSInventor: Alyssa SieberCROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of and priority to U. S. Provisional Patent Application No. 63 / 713,488, filed October 29, 2024, titled "Intelligent Fluid Monitoring Cup System for Healthcare Settings," the entire contents of which are incorporated herein by reference.FIELD OF T HE INVENT ION

[0002] The present invention relates generally to medical monitoring devices and healthcare information systems. More particularly, the invention relates to fluid intake monitoring systems for clinical healthcare settings that integrate with electronic medical records and provide realtime patient data management. The invention further relates to intelligent monitoring apparatus and methods for tracking and recording patient fluid consumption in hospital and clinical environments.BACKGROUND OF THE INVENTION

[0003] Fluid intake monitoring is a critical aspect of patient care, particularly for individuals with conditions such as congestive heart failure, kidney failure, or those preparing for surgery. Accurate tracking of fluid consumption is essential for several reasons. For congestive heart failure patients, excessive fluid intake can exacerbate their condition, potentially leading to fluid accumulation in the lungs and other parts of the body. Proper fluid management is crucial for these patients' recovery and well-being. Inaccurate fluid tracking can result in prolonged hospital stays, increasing both patient discomfort and healthcare costs. A typical mild exacerbation of congestive heart failure may require a 2-3 day hospitalization, costing tens of thousands of dollars per day in the United States.

[0004] Current fluid monitoring methods face several challenges that have persisted despite technological advances in healthcare. The search of existing solutions reveals that while consumer-grade "smart." hydration bottles have existed for years, they fail to address the unique requirements of the clinical environment, such as robust hygiene protocols, direct EMR integration, and patient-specific workflow features. Manual recording of fluid intake remains prone to errors and inconsistencies, with patients often needing to ask nurses about their remaining fluid allowance, which strains nursing resources.

[0005] Existing consumer smart cups, such as those disclosed in US 2017 / 0340147 Al to Leech and US 9,382,107 B2 to Pacey, each of which are incorporated herein by reference, are fundamentally designed for personal wellness tracking rather than clinical applications. These devices lack essential features for hospital use, including: (1) ergonomic design elements such asdouble handles for weakened patients; (2) sterilizable shells or disposable liner systems for hospital hygiene protocols; (3) dedicated NPO (Nil Per Os) mode with clear on-screen indicators; (4) barcode systems for linking devices to specific patient EMRs; (5) direct communicative links using healthcare standards like HL 7 or FHIR for integration with systems like Epic or Cerner; and (6) nurse verification workflows for data integrity.

[0006] Traditional cup designs present additional challenges for patient populations requiring fluid monitoring. Standard hospital cups are often too large and heavy for weakened patients to handle comfortably, and conventional lids that must be pulled up create accessibility barriers for patients with limited dexterity or strength. The updated twist-on lid design addresses these limitations by providing easier access through rotational motion rather than vertical lifting, which is particularly beneficial for patients with weakened grip strength or mobility issues.

[0007] Measurement accuracy represents another significant challenge in existing approaches. Early measurement systems relied on estimation-based methods or external measurement devices like measurement tape that provided limited precision and were subject to user error. The transition to sensor-based measurement systems addresses these limitations through automated, high-precision monitoring capabilities.

[0008] Traditional liquid sensing approaches face significant limitations that have not been adequately addressed in the prior art. Estimation-based measurement methods rely on visual assessment or timing mechanisms that are inherently imprecise and subject to substantial user error, particularly in clinical settings where accuracy is critical. External measurement devices, such as measurement tape systems, provide only limited precision and require manual intervention that introduces additional opportunities for error. Conventional liquid level detection systems suffer from susceptibility to environmental interference, including proximity effects from users or external objects, which can cause measurement drift and compromise accuracy. These approaches fail to achieve the sub-millimeter precision required for clinical applications where exact fluid volumes are essential for patient safety and treatment efficacy. The persistent reliance on manual estimation and measurement techniques demonstrates a fundamental gap in the art for automated, high-precision liquid sensing solutions suitable for healthcare environments.

[0009] The persistent gap between existing consumer devices and clinical requirements demonstrates the long-felt need for a comprehensive solution. Clinical hydration monitoring systems like those described in US 2009 / 0043222 Al to Licandro, incorporated herein by reference, attempt to address hydration monitoring through bioelectrical impedance rather than direct fluid intake measurement, indicating that even clinical approaches have not successfully addressed the need for direct oral fluid intake monitoring in a hospital setting.

[0010] Healthcare IT integration represents another critical gap in existing solutions. However, no existing solution has successfully combined all necessary elements: precise measurement capabilities, clinical ergonomics and hygiene features, comprehensive clinical workflow software, and seamless integration with hospital electronic medical record systems.

[0011] These persistent challenges highlight the need for an innovative solution that can accurately monitor and record fluid intake, provide real-time information to patients and caregivers, incorporate advanced sensor technology for precise measurement, utilize improved container design for patient accessibility, and integrate seamlessly with existing hospital systems to ensure comprehensive clinical workflow management.SUMMARY Of THE INVENTION

[0012] The present invention in accordance with an embodiment addresses the critical challenges in clinical fluid monitoring through an intelligent fluid monitoring cup system that combines advanced sensor technology, ergonomic design improvements, and seamless healthcare integration to provide accurate, real-time fluid intake tracking for patients in healthcare settings.

[0013] A primary advantage of the present invention in accordance with an embodiment lies in its implementation of capacitive sensor technology for precise fluid level measurement. The capacitive sensing approach provides liquid level sensing with resolution capabilities of less than 1mm, representing a substantial improvement over traditional estimation-based methods that are prone to user error and environmental interference. The capacitive sensor configuration utilizes changes in dielectric constant of the cup contents to accurately measure fluid levels, offering sensitivity capable of detecting changes in fluid level of less than 0.5mm, which provides approximately three times the sensitivity required for clinical applications. This high-precision measurement capability eliminates the inaccuracies associated with manual estimation and external measurement devices that have plagued existing fluid monitoring approaches.

[0014] The invention in accordance with an embodiment incorporates significant design improvements that address patient accessibility and usability challenges identified in traditional hospital fluid monitoring systems. A key advancement is the implementation of an improved twist-on lid design that replaces conventional lids requiring vertical lifting motion. This twist-on screw top configuration provides easier access through rotational motion rather than vertical lifting, which is particularly beneficial for patients with weakened grip strength, limited dexterity, or mobility issues commonly encountered in clinical settings. This design improvement directly addresses the accessibility barriers that prevent effective fluid monitoring in patient populations requiring such care.

[0015] The invention in accordance with an embodiment further advances clinical fluid monitoring through increased container capacity, with the cup body designed to hold at least 750mL compared to traditional monitoring cups with insufficient volume around 500mL. This larger capacity reduces refilling frequency while maintaining manageable weight for patient use, thereby minimizing opportunities for measurement error and workflow disruption that occur with frequent refilling cycles.

[0016] Integration advantages of the present invention in accordance with an embodiment include comprehensive compatibility with widely used hospital charting systems such as Epic, Cerner, and Meditech through direct communicative links using healthcare interoperability standards like HL7 and FHIR. The system incorporates a barcode identification system that enables scanning to link the device to specific patient electronic medical records, ensuring accurate data association and eliminating manual transcription errors. A nurse verification mechanism provides professional oversight to confirm automated readings before permanent recording in patient medical records, enhancing data integrity and patient safety.

[0017] The invention's software capabilities in accordance with an embodiment provide clinical workflow optimization through specialized features including a dedicated NPO (Nil Per Os) mode with clear visual indicators, configuration lock functions to prevent unauthorized changes, manual fluid intake recording for consumption outside the monitored cup, and patient discharge / reset functionality for efficient device preparation between patients. These features work synergistically to create a comprehensive clinical workflow management tool that addresses the unique requirements of hospital environments.

[0018] Hygiene and infection control advantages in accordance with an embodiment are achieved through the incorporation of either sterilizable shell components or disposable liner systems, allowing for efficient cleaning or replacement between patient uses while maintaining the integrity of electronic measurement components. The spill-proof design features, similar to those found in specialized drinking vessels, help prevent accidental spills and ensure accurate fluid intake monitoring, particul rly beneficial for patients with weakened grip strength or limited mobility.

[0019] The ergonomic design improvements in accordance with an embodiment include double handles that provide enhanced stability and ease of use for patients with various physical limitations, addressing the challenges posed by standard hospital cups that are often too large and heavy for weakened patients to handle comfortably. The lightweight construction accommodates patients with reduced strength while maintaining sufficient capacity for clinical hydration monitoring requirements.

[0020] By providing these integrated advantages - -precise capacitive sensing technology, improved accessibility through twist-on lid design, enhanced capacity, seamless healthcare IT integration, and comprehensive clinical workflow features- -the present invention addresses the long-felt need for accurate, automated fluid intake monitoring in clinical settings. The invention has the potential to improve patient care, reduce healthcare provider burden, enhance data accuracy, and ultimately improve outcomes for patients with conditions requiring strict fluid management, such as congestive heart failure, kidney failure, and pre-surgical patients.BRIEF DESCRIPTION OF THE FIGURES

Thi s level of accuracy is crucial for patients with conditions such as congestive heart failure, where strict fluid management is essential for effective treatment.

[0046] The fluid monitoring mechanism in accordance with an embodiment of the invention preferably utilizes capacitive sensor technology for precise fluid level measurement. Capacitive sensing in accordance with an embodiment of the invention provides liquid level detection by measuring changes in dielectric constant of the cup contents, offering substantially greater accuracy than estimation-based methods or external measurement devices. The capacitive sensor approach in accordance with an embodiment of the invention eliminates the susceptibility to environmental interference and proximity effects that compromise the accuracy of conventional liquid level detection systems.

[0047] The capacitive sensor technology in accordance with an embodiment of the invention provides liquid level sensing with resolution capabilities of less than 1mm, representing a substantial improvement over traditional measurement approaches. The sensitivity of the capacitive sensor configuration in accordance with an embodiment of the invention is capable of detecting changes in fluid level of less than 0.5mm, which provides approximately three times the sensitivity required for clinical applications where exact fluid volumes are essential for patient safety and treatment efficacy. This high-precision measurement capability in accordance with an embodiment of the invention eliminates the inaccuracies associated with manual estimation and external measurement devices that have plagued existing fluid monitoring approaches.

[0048] The capacitive sensor implementation in accordance with an embodiment of the invention comprises a flexible sensor design that can be applied to the exterior of the cup with self-adhesive backing.

The selection of sensor technology in accordance with an embodiment of the invention focuses the patent protection on the unique clinical application of automated patient fluid intake measurement rather than the specific measurement method employed.

[0050] The fluid flow monitoring mechanism in an embodiment of the invention can be implemented using various types of flow meters, each suited to the unique requirements of the cup design and fluid monitoring needs. One potential implementation is the use of a turbine flow meter, which can be integrated into the base of the cup or within the straw mechanism.

[0051] In the turbine flow meter configuration, a small turbine is placed in the fluid path. As liquid flows through, it causes the turbine to rotate. The rotation speed is directly proportional to the flow rate, allowing for accurate measurement of fluid volume. This type of flow meter is particularly suitable for the preferred embodiment of the invention due to its compact size and ability to measure low flow rates typically associated with drinking.

[0052] Another possible implementation is an ultrasonic flow meter. This non-invasive option uses ultrasonic waves to measure fluid flow without direct contact with the liquid. In this configuration, ultrasonic transducers could be embedded in the walls of the cup, sending and receiving sound waves through the fluid. The time difference between the upstream and downstream ultrasonic pulses is used to calculate the flow rate. This method is advantageous as it has no moving parts, reducing the risk of mechanical failure and making it easier to maintain hygiene standards.

[0053] For more precise measurements, especially in medical settings where accuracy is crucial, a Coriolis flow meter could be considered. Although typically larger and more complex, miniaturized versions could potentially be integrated into the base of the cup. Coriolis metersmeasure mass flow directly, providing highly accurate readings regardless of fluid viscosity or temperature.

[0054] Regardless of the specific flow meter type chosen, the integration into the cup structure is designed to be seamless and non-intrusive. For example, in the case of a turbine flow meter, it could be housed in a sealed compartment at the base of the cup, with only the necessary inlet and outlet ports exposed to the fluid path. This design ensures that the flow meter components do not come into direct contact with the consumable liquid, maintaining hygiene and facilitating easy cleaning or sterilization of the cup.

[0055] The data collected by the flow meter is transferred to other aspects of the invention through a series of steps. First, the raw data from the flow meter (e.g., rotation speed for a turbine meter or time differences for an ultrasonic meter) is converted into a digital signal by an analog-to-digital converter (ADC) integrated into the cup's electronic components.

[0056] This digital signal is then processed by the small computing device within the cup. The device applies calibration factors and algorithms to convert the raw data into meaningful fluid volume measurements. These measurements are then used to update the display in real-time, showing the patient and healthcare providers the current fluid intake status.

[0057] Simultaneously, the processed data is prepared for transmission to the patient's electronic medical records (EMR) system. The preferred embodiment of the invention formats this data according to healthcare interoperability standards such as HL 7 or FHIR. The formatted data is then transmitted via the cup's wireless or wired connectivity options to the hospital's EMR system, ensuring that the patient's fluid intake information is always up-to-date and accessible to the healthcare team.

[0058] This comprehensive approach to fluid flow monitoring and data integration enables the preferred embodiment of the invention to provide accurate, real-time fluid intake tracking. By leveraging advanced flow meter technology and seamless data transfer mechanisms, the invention addresses the critical need for precise fluid management in healthcare settings, particul rly for patients with conditions like congestive heart failure where strict fluid control is essential for effective treatment.

[0059] The preferred embodiment of the invention establishes a communicative link to the patient's electronic medical records (EMR). This connectivity allows for seamless integration with existing hospital information systems, such as Epic, Cerner, or Meditech, The communicative link enables real-time updates of fluid intake data directly to the patient's charts, eliminating the need for manual data entry and reducing the risk of transcription errors. This feature enhances the efficiency of healthcare delivery by providing immediate access to critical fluid intake information for all authorized healthcare providers involved in the patient's care.

[0060] The electronic components of an embodiment of the invention work in concert to create a comprehensive fluid monitoring system. The small computing device processes data from the fluid flow monitoring mechanism, displays relevant information on the integrated screen, and transmits updates to the patient's EMR through the established communicative link. This integrated approach ensures that fluid intake is accurately measured, clearly communicated, and properly documented, addressing many of the challenges associated with traditional fluid monitoring methods in healthcare settings.

[0061] The display features of an embodiment of the invention are designed to provide clear, accessible information to patients, healthcare providers, and visitors.

By leveraging standardized data formats, multiple connectivity options, and robust verification mechanisms, the invention addresses the challenges of accurate fluid intake tracking and timely information sharing in healthcare settings.

[0085] The present inventor has identified several patient populations that would benefit from utilization of the invention in accordance with various embodiments and exemplary intended uses. The intelligent fluid monitoring cup system provides significant benefits for various patient populations requiring strict fluid management, including but not limited to the following:

[0086] For congestive heart failure (CHF) patients, the invention in embodiments offers precise tracking of fluid intake, helping prevent fluid overload that can lead to CHF exacerbation. By displaying real-time fluid consumption data and remaining allowances, the system enables patients and healthcare providers to adhere to prescribed fluid restrictions, potentially reducing the risk of hospitalization and associated costs.

[0087] The NPO (Nil Per Os) mode feature is particularly beneficial for pre-operative patients. This clear visual indicator helps ensure compliance with pre-surgical fluid restrictions, reducing the risk of complications during anesthesia and surgery.

[0088] For patients with end-stage renal failure or those on dialysis, the invention in an embodiment aids in managing fluid intake between treatments. By preventing fluid overload, it can help reduce the strain on dialysis machines and potentially improve treatment efficacy. The system's accurate tracking and display of fluid consumption support patients in maintaining their prescribed fluid limits, potentially mitigating symptoms such as difficulty breathing and swelling.

[0089] Burn patients, especially those in the critical first 48 hours post-injury, can benefit significantly from the system's precise fluid monitoring capabilities. The invention in an embodiment allows healthcare providers to input patient-specific fluid allowances based on weight and burn percentage calculations. By ensuring adherence to these carefully determined fluid resuscitation protocols, the system helps prevent both under-hydration and over-hydration, potentially reducing the risk of complications such as pulmonary edema.

[0090] The present invention in accordance with an embodiment of the invention differs substantially from consumer smart hydration devices found in the prior art, such as those disclosed in US 2017 / 0340147 Al to Leech and US 9,382,107 B2 to Pacey. 3 Consumer devices in accordance with an embodiment of the invention lack essential clinical features including: ergonomic design elements such as double handles for weakened patients; sterilizable shells or disposable liner systems required for hospital hygiene protocols; dedicated NPO (Nil Per Os) mode with clear on-screen clinical indicators; barcode systems specifically designed for linking devices to patient electronic medical records; direct communicative links using healthcare interoperability standards like HL 7 or FHIR; and nurse verification workflows essential for clinical data integrity.

[0091] The invention in accordance with an embodiment of the invention also distinguishes from indirect clinical monitoring approaches found in the prior art. Clinical hydration monitoring systems like those described in US 2009 / 0043222 Al to Licandro attempt to address hydration monitoring through bioelectrical impedance measurement of body segments rather than direct fluid intake measurement from a drinking vessel. 3 This fundamental difference in approach demonstrates that the present invention in accordance with an embodiment of the invention addresses the unmet need for direct oral fluid intake monitoring in hospital settings through a novel combination of precise measurement technology and clinical workflow integration.

[0092] In summary, the present invention in accordance with an embodiment provides a comprehensive solution to the longstanding challenges of clinical fluid monitoring through the synergistic integration of advanced sensor technology, thoughtful ergonomic design, and seamless healthcare system integration. The combination of capacitive sensor technology capable of sub-millimeter precision measurement, the improved twist-on lid design for enhanced patient accessibility, and the increased 750mL capacity work together to address both the technical and practical limitations of existing approaches. The invention's clinical workflow features, including NPO mode indication, nurse verification mechanisms, and direct EMR integration using healthcare interoperability standards, transform fluid monitoring from a manual, error-prone process into an automated, accurate, and efficient clinical tool. Byincorporating hospital-grade hygiene protocols, ergonomic design elements such as double handles, and comprehensive software functionality, the invention in accordance with an embodiment creates a complete ecosystem that not only measures fluid intake with unprecedented accuracy but also integrates seamlessly into existing hospital workflows. The result is a medical device that has the potential to significantly improve patient outcomes for conditions requiring strict fluid management while reducing healthcare provider burden and minimizing the risk of costly treatment complications associated with inaccurate fluid monitoring. This comprehensive approach to intelligent fluid monitoring represents a substantial advancement over existing solutions and addresses the critical, unmet need for precise, automated fluid intake tracking in clinical healthcare settings.
