[0005] Conventional oxygen masks comprise tent like structures which are strapped over the nose and mouth of the patient, often using an elastic band or bands behind the patient's ears or head. Oxygen is fed from a supply through a tube into the bottom portion of the mask at the front of the patient. Many problems exist with such masks, including the fact that many patients find them claustrophobic, the mask must be removed for the patient to speak or eat, thereby discontinuing therapy and the face mask creates irregular infusion of oxygen by the patient since exhaled air from the patient is mixed with oxygen in the mask.

[0006] Conventional nose cannula oxygen delivery systems employ an oxygen delivery tube with tubular, open ended nasal prongs at the delivery end of the tube for insertion into a patient's nasal passages. The oxygen delivery tube and nasal cannula are supported in position by a tube wrapped about the patient's ears or head, making the system both difficult to handle and uncomfortable since it applies downward pressure on the patient's ears when the patient is in a seated position. As well, patients often get nose bleeds from the dryness of the nasal cannula.

[0027] DETAILED DESCRIPTION OF THE INVENTION:

[0028] In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without these specific details.

[0029] Reference herein to “one embodiment” or “another embodiment” means that a particular feature, structure, or characteristics described in connection with the embodiment can be included in at least one embodiment of the invention. The appearances of the phrase “in one embodiment” in various places in a specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Further, the diagrams representing one or more embodiments of the invention do not inherently indicate any particular order nor imply any limitations in the invention.

[0030] As used herein, the term “plurality" refers to the presence of more than one of the referenced item and the terms “a”, “an”, and “at least” do not denote a limitation of quantity, but rather denote the presence of at least one of the referenced item. In a preferred embodiment, the nasal embedded device for enhanced oxygen delivery (100) is structurally configured to optimize and regulate respiratory gas flow to a user’s nasal passageways. The device comprises at least two nasal ports (300), each including an upper engagement portion (301) adapted for secure nostril interface, and a lower interface portion (302) configured for coupling with a centrally positioned tee valve (200). The tee valve (200) features a valve body comprising three discrete connectors (201, 202, 203), wherein the first (201) and second (202) connectors interface with the nasal ports (300), and the third connector (203) is fluidly connected to an exhalation valve (204) incorporating a plurality of exit apertures (302) to facilitate gas diffusion. A bent-up pipe (400) traverses the tee valve (200), with a first portion (401) projecting outwardly from the valve body and a second portion (402) internally affixed (404) within the valve structure to support directional gas flow. Optionally, an umbrella pin valve (500) may be inserted into the exhalation valve (204), wherein its expandable configuration facilitates a secure seal, thereby regulating internal pressure dynamics. The device (100) is engineered to interface with an external oxygen source or respiratory pump, providing precise modulation of oxygen delivery while preventing overpressurization, thus ensuring controlled, safe, and efficient ventilation to the user.

[0031] An embodiment of the present invention provides at least two respiration delivery ports (300), each comprising a top portion (301) configured for attachment to a user's nostrils and a bottom portion (302) designed to engage with the tee valve (200). The ports (300) further include adjustable fasteners (304), allowing for user-specific modifications to achieve a comfortable and secure fit. The top portion (301) of each port (300) comprises a soft, biocompatible elastomeric material to enhance comfort within the user's nostrils. These ports (300) are equipped with an adjustable collar that enables customization of the nostril opening size. The design of the ports (300) ensures optimal user comfort during extended use by accommodating variations in nostril size, thereby providing a secure and personalized fit. In this embodiment, the inclusion of the adjustable collar enhances the versatility of the device, allowing it to be tailored to individual user requirements, while simultaneously maintaining efficient and consistent respiratory delivery.

[0032] In another embodiment of the present invention, the upper segment (301A) is configured to form a sealed interface with the user's nostrils, thereby ensuring minimal air leakage and maintaining system integrity during use. The lower segment (302A) of the device (100) is adapted to facilitate secure and leakresistant connection to the corresponding threaded connectors of the tee valve assembly (200). The dual-configuration ensures both biocompatible interface with the user and robust integration with the fluid control system.

[0033] One embodiment of the present invention relates to a tee valve (200) comprising a valve body configured with at least three distinct connectors (201, 202, 203). The first connector (201) and the second connector (202) are positioned on a lower portion (302) of the valve body, while the third connector (203) is coupled to an exhalation valve (204). The exhalation valve (204) is provided with a plurality of exit apertures (302) to enable controlled fluid egress. The valve body further includes a pair of integrally formed openings designed to receive a bent-up pipe (400). The bent-up pipe (400) comprises a first portion (401) that extends externally from the valve body and a second portion (402) that is internally connected at an interface (404) within the valve body.

[0034] Another embodiment of the present invention the bent-up pipe (400) is integrally molded with the tee valve (200) and configured with a curvature angle between 45 and 90 degrees to direct oxygen flow toward the nasal ports (300). This internal arrangement of the bent-up pipe (400) forms a fluid passage that establishes communication among the first connector (201), the second connector (202), the third connector (203), and the exhalation valve (204), thereby facilitating throughout the tee valve (200) assembly. One of the embodiment of the present invention is the valve body of the tee valve (200) is formed from a rigid, medical-grade polymer that is resistant to thermal sterilization. In this embodiment the internal connection (404) between the second portion (402) of the bent-up pipe (400) and the tee valve (200) includes a threaded interface for attachment and modular replacement. In this embodiment the valve body is configured in a Y-shaped geometry thereby facilitating a more streamlined flow path for oxygen delivery.

[0035] Yet another embodiment of the present invention provides an umbrella pin valve (500) configured for insertion into the exhalation valve (204) of the respiratory device (100). The umbrella pin valve (500) is constructed to expand upon insertion, thereby establishing an airtight seal within the exhalation valve (204). The device (100) is further adapted to regulate the flow of oxygen delivered from an external respiratory pump to the patient, wherein said configuration ensures prevention of oxygen over-delivery. This facilitates precise, controlled, and efficient ventilation tailored to the user’s respiratory requirements. In this embodiment of the present invention is to provide the umbrella pin valve (500) includes a radially expandable skirt that conforms to the interior wall of the exhalation valve (204) to ensure a fluid-tight seal.

[0036] In second embodiment of the present invention, the oxygen delivery apparatus is configured to operate without the inclusion of an umbrella pin valve (500). Instead, this embodiment utilizes a passive, regulated system for unidirectional oxygen flow, thereby simplifying the device architecture while maintaining effective therapeutic delivery. The present invention remains directed toward providing enhanced oxygen delivery through a compact nasal interface that incorporates a tee valve (200) configuration designed to facilitate regulated flow dynamics based solely on geometric and structural attributes.

[0037] The removal of the umbrella pin valve (500) serves to reduce the number of internal moving parts, thereby decreasing the likelihood of mechanical failure and increasing the overall reliability and manufacturability of the device. In this embodiment, passive flow regulation is achieved via the internal geometry of the tee valve (200) and a bent pipe (400) that directs gas flow in a preferential direction. The bent- up pipe (400), in concert with the shaped flow channels within the tee structure, enables controlled, unidirectional oxygen delivery by leveraging natural pressure differentials and path resistance rather than relying on expansion or compression seals.

[0038] Furthermore, the internal surfaces of the tee valve (200) are configured to direct inhalation and exhalation gases through separate, non-overlapping flow pathways. These channels are formed to maintain unidirectional movement and minimize backflow, ensuring that oxygen is delivered efficiently during inhalation while exhaled gases are diverted away from the oxygen supply line. The absence of active valve elements eliminates the need for precise mechanical tolerances and alignment, thereby simplifying both assembly and routine maintenance.

[0039] In this embodiment is particularly advantageous for applications involving low-to-moderate oxygen therapy requirements, where precise dosage and pressure regulation can be externally managed, such as through a calibrated respiratory pump or pressure-regulated oxygen source. The elimination of expansion-based internal seals not only enhances durability and user comfort but also reduces the potential for leak paths and insertion complexity during clinical or at-home use. Consequently, this embodiment supports both improved patient compliance and streamlined manufacturing processes, making it well-suited for scalable production and widespread deployment in therapeutic oxygen delivery systems.

The device configured to regulate oxygen flow through an integrated unidirectional exhalation valve (204) positioned exit apertures (302). This configuration prevents excessive oxygen delivery, thereby optimizing ventilation efficiency and patient safety. When operably connected to an external respiratory pump, the nasal embedded device (100) ensures a consistent and controlled oxygen supply tailored to the user’s specific respiratory requirements.

[0041] Figure 2 illustrates, in a second embodiment, the front view configuration of the nasal embedded device (100), this time including the umbrella pin valve (500).

[0042] In this embodiment, the device (100) is configured to regulate oxygen flow through an integrated unidirectional exhalation valve (204) and positioned exit apertures (302). The umbrella pin valve (500) is inserted into the exhalation valve (204), enhancing the control mechanism. This configuration helps prevent excessive oxygen delivery, thereby optimizing ventilation efficiency and ensuring patient safety. When operably connected to an external respiratory pump, the nasal embedded device (100) provides a consistent and controlled oxygen supply tailored to the user’s specific respiratory requirements.

[0043] Figure 3 illustrates an embodiment of the configuration of a nasal embedded device (100) positioned within the nasal cavity. In this embodiment, the device is depicted in an assembled state, with all individual components clearly visible. The nasal embedded device (100) is configured for insertion into the nasal passage, comprising multiple interconnected components, each designed to perform distinct functions. The configuration of these components ensures precise placement and functionality within the nasal anatomy. The device is designed to be ergonomically compatible with the nasal passage, ensuring minimal disruption to the natural airflow while achieving its intended purpose. The individual parts of the device include elements for securing, stabilizing, and optimizing its performance within the nasal cavity, while also allowing for seamless integration with other respiratory delivery port (300) or monitoring systems. The interconnection of the components is configured to provide both structural integrity and flexibility, enabling the device to adapt to various nasal anatomies for improved efficacy and comfort during use. Figure 4 provides an exploded view of the tee valve assembly (200) according to one embodiment of the present invention. In this configuration, the tee valve (200) is shown coupled with two tee connectors: a first tee connector (201) and a second tee connector (202). The first tee connector (201) is equipped with an internal grip (201 A), which is specifically designed to securely fasten respiration delivery ports. Similarly, the second tee connector (202) also incorporates an internal grip (202A) that facilitates the attachment of respiration delivery ports (300), ensuring a stable and reliable connection. On the ventral side of the tee valve (200), a joint (203) is positioned, which is situated opposite to both the first and second tee connectors (201, 202). This joint is integral to the overall configuration, enabling the proper alignment and function of the assembly. The bottom portion of the tee valve (200) is fitted with an exhalation valve (204), which plays a critical role in regulating airflow during inhalation processes.

[0044] Further, the tee valve assembly (200) includes two distinct holes (205), which are specifically designed for the attachment of a bent pipe (400). These holes allow for secure integration of the pipe, enabling the necessary flow of air or respiratory gases in alignment with the device's intended function. The overall design of the tee valve assembly ensures seamless attachment and secure operation within the respiratory system, enhancing the device's efficiency and reliability.

[0045] One embodiment of Figure 5 illustrates the side view of the right respiratory delivery port (300). In this embodiment, the top portion 301 features an internal groove (301A), which is designed to securely attach to the user's nostrils. The bottom portion (302) incorporates a bottom internal groove (302A), which facilitates attachment to the tee valve (200) for proper securing. Furthermore, a fastener (304) is affixed to the central body (303) of the ports (300), ensuring stable and reliable connection. In one embodiment, Figure 6 shows a side view of the left port (300A). In this design, the upper section (301A) contains an internal groove (301A), crafted to securely fit within the user's nostrils. The lower section (302B) features a bottom internal groove (302B) that enables a secure attachment to the tee valve (200), ensuring proper stabilization. Furthermore, a fastener (304A) is attached to the central body (3O3A) of the port (300A), providing a firm and reliable connection.

[0046] In one embodiment, Figure 7 illustrates a bottom view of the right respiratory port (300). In this embodiment, the texture of the bottom portion of the port (300) is depicted. Furthermore, the internal exit apparatuses (302A, 302B, 302C, 302D, 302E, 302F, 302G) are shown, designed in such a way that they facilitate easy attachment to the tee valve (200). The configuration of these exit apparatuses 302 ensures a secure and efficient connection to the tee valve (200) for optimal functionality.

[0047] One embodiment, as depicted in Figure 8, illustrates a side view of a bent pipe (400), wherein the upper portion of the bent pipe (401) is internally connected to the lower portion (302) of the ports (300). In this particular embodiment, there are two bent pipe (400), each functioning with the same mechanism. The central portion (404) of the bent pipe (400) is situated between two grooves: the first groove (403 A) and the second groove (403B), which are positioned in proximity to the bottom portion (302) of the port (300).

[0048] In one embodiment the figure 9 illustrates the front view of the umbrella pin valve (500) is shown. The top portion (501) of the umbrella pin valve (500) is securely affixed to a circular disc (502). A cylindrical shaft (504) is connected to the circular disc (502), which serves as the structural support for the umbrella pin valve (500) mechanism. The cylindrical shaft (504) features two grooves (503 and 503A) that are positioned to facilitate a secure engagement when coupling the umbrella pin valve (500) to the exhalation valve (204). These grooves (503 and 503A) are designed to ensure a friction-fit connection, preventing any slippage during the attachment process and ensuring reliable operation. The precise alignment and configuration of the grooves (503, 503 A) contribute to the stable and secure attachment of the umbrella pin valve (500) to the exhalation valve (204), ensuring optimal performance and sealing integrity.

[0049] In one embodiment, Figure 10 illustrates a flow diagram depicting a method for delivering controlled respiratory gas via a nasal-embedded device. The process begins by connecting a specialized tee valve (200) to an external respiratory pump. The tee valve is equipped with three threaded connectors, at least one unidirectional exhalation valve (204), and multiple exit apertures (302) designed to manage excess gas flow. Once connected, two bent pipes (400) are attached to the threaded connectors of the tee valve (200). The second end of each pipe is routed internally and connected to the bottom portion (201) of a corresponding respiration delivery port (300). These delivery ports (300) are securely attached to the user’s nostrils, with the top portion of each port forming a sealed interface to ensure efficient gas delivery. After the setup is complete, respiratory gas is transmitted from the external pump, flowing through the tee valve (200) and into the bent pipe (400), then directly into the user’s nostrils via the delivery ports (300). Gas flow is carefully regulated by the unidirectional exhalation valve (204), which allows gas to enter the nostrils only during inhalation. Any excess gas that is not inhaled is safely released through the exit apertures in the tee valve (200).

[0050] This dual-path flow control ensures that the user receives a precisely regulated amount of respiratory gas, preventing over-oxygenation and ensuring a safe, efficient, and therapeutic ventilation experience.

[0051] Regulation of oxygen flow is achieved through coordinated interaction between the tee valve and the inhalation valve, ensuring controlled oxygen delivery to the nostril ports (300). The umbrella pin valve (500) plays a critical role in preventing over-delivery by dynamically sealing the inhalation valve when excessive oxygen flow is detected, thus maintaining therapeutic and safe oxygen levels throughout the administration cycle.

[0052] The present invention offers significant advantages in the field of respiratory therapy through its advanced nasal-embedded device (100) design, which ensures precise and controlled delivery of respiratory gases. One of the primary technical advantages lies in the integration of a tee valve assembly (200) featuring at least one unidirectional exhalation valve (204) and a plurality of exit apertures (302), which collectively facilitate the regulated flow of gas while preventing the build-up of excess pressure within the system. The staggered configuration of the exit apertures enhances laminar flow characteristics, minimizing turbulence and resistance, thus improving the efficiency of oxygen delivery.

[0053] Furthermore, the modular construction comprising respiration delivery ports (300) with adjustable collars, antimicrobial coatings, and customizable fasteners enhances patient comfort, ensures a secure anatomical fit, and reduces the risk of microbial contamination during prolonged use. The incorporation of Bent -up pipes (400) facilitates effective routing of respiratory gases, supporting both inhalation and passive exhalation management without compromising the integrity of the seal or obstructing airflow.

[0054] Collectively, the components of the invention operate synergistically to ensure optimized airflow dynamics, customizable fit for various nasal anatomies, hygienic operation, and prolonged functionality under repeated use positioning the invention as a robust and effective solution for controlled respiratory support in both clinical and homecare settings.

[0055] Table 1

[0056] In one embodiment table 1 of the present invention, the nasal-embedded oxygen delivery device, demonstrates substantial performance enhancements over the standard nasal cannula across multiple critical parameters. Oxygen delivery efficiency, a pivotal metric, improved by 27%, with the device achieving up to 92% inhaled O2 compared to 60-65% with conventional systems, indicating more effective oxygen utilization. This is complemented by a 56.5% reduction in gas flow turbulence (from 10-14.5 Pa to 1-6.3 Pa), suggesting a significant shift toward more laminar flow dynamics, which enhances delivery precision and user comfort. Correspondingly, the user comfort score increased by 61%, ranging from 5 to 8.7 on a 10-point scale, due to ergonomic design and reduced nasal irritation.

[0057] Fit stability also improved dramatically, with displacement minimized to 0.4- 0.6 mm (an 81% reduction), ensuring consistent positioning and reducing the need for readjustment during use. The device incorporates an antimicrobial coating, which effectively reduced microbial load by 79.5% after 8 hours of continuous use, thereby enhancing patient safety. Oxygen wastage was significantly reduced by 75%, conserving medical oxygen resources and improving cost efficiency. Furthermore, CO2 clearance efficiency was markedly enhanced, increasing by 58%, which is critical in preventing CO2 retention in patients with respiratory compromise.

[0058] Seal integrity improved as well, with leak rates dropping by 82%, contributing to both enhanced oxygen delivery and infection control. Device longevity also saw substantial improvement; reusability increased by 240%, with the nasal- embedded device enduring up to 85 usage cycles before failure, compared to 25 cycles for the standard cannula. Lastly, the inhalation valve response time was reduced by 59% (from 110ms to 45ms), ensuring faster synchronization with the patient's respiratory cycle, and leading to a more responsive and efficient oxygen delivery system. Collectively, these advancements position the present invention as a superior alternative to conventional nasal cannulas in both clinical and home-care settings.

[0059] Table 2

[0060] One of the embodiments of the present invention table 2 is analytical explanation of the results of the nasal embedded 100 the respiratory delivery device underwent comprehensive evaluation across multiple performance parameters, demonstrating robust functionality and user-centric design. In terms of device fit and comfort, the system achieved a secure attachment of the delivery ports to the nostrils, ensuring a snug fit with minimal irritation in the majority of users. This was further enhanced by the use of adjustable collars and fastening mechanisms, which significantly improved overall user comfort. Seal integrity, particularly within the Umbrella Pin Valve (500), was maintained through an expansion and friction-fit mechanism that yielded an airtight seal without detectable air leakage. The use of a textured surface and flexible thermoplastic elastomer (TPE) material played a critical role in achieving this superior sealing performance.

[0061] Same embodiment of the Airflow regulation, facilitated by the Tee Valve (200), employed staggered exit apertures and a responsive inhalation valve to deliver smooth, laminar airflow with minimal turbulence. This design effectively minimized pressure drops and obstructions, contributing to stable respiratory dynamics. Regarding material performance, components made from medical-grade silicone and TPE exhibited excellent biocompatibility and resistance to mechanical deformation, showing no structural degradation or signs of irritation after prolonged use, thereby affirming the device’s durability and patient compatibility.

[0062] The CO2 expulsion efficiency, enabled by the bent up-pipe (400) and tee valve integration, demonstrated effective removal of exhaled gases without backflow, maintaining consistent ventilation. The lightweight, corrosion-resistant construction of the pipe contributed to sustained functional performance under extended operational conditions. Oxygen delivery precision was achieved through a closed-loop system involving a respiratory pump and real-time monitoring, maintaining target flow rates within ±2% deviation, which ensured accurate and consistent oxygen supply.

[0063] In terms of hygienic maintenance, the application of an antimicrobial coating to internal surfaces effectively inhibited bacterial growth over a 24 -hour test period, promoting sanitary use during prolonged application. The device also demonstrated a high degree of adaptability to user variability, with adjustable components accommodating a wide range of nasal anatomies, achieving a successful fit in 95% of tested users. Finally, the system's operational stability was confirmed through a 12-hour continuous-use simulation, during which the device maintained structural integrity and consistent airflow. Its ergonomic design prevented dislodgement and preserved alignment, ensuring reliable performance during dynamic conditions.

[0064] A third connector (203) of the tee valve (200) is coupled to an exhalation valve (204), which is configured with a plurality of exit apertures (302) for pressure regulation and excess gas discharge. An umbrella pin valve (500) is operatively positioned within the exhalation valve (204). The umbrella pin valve (500) is configured to expand upon insertion, thereby forming a dynamic seal within the exhalation valve (204). The sealing mechanism is sensitive to pressure variations within the system and functions to regulate the flow of oxygen based on real-time respiratory demand.

[0065] Oxygen is routed into the device (100) from an external respiratory source via a bent-up pipe (400). The bent-up pipe (400) consists of a first portion (401), which remains external and interfaces with the external respiratory pump, and a second portion (402), which is internally connected (404) within the tee valve (200) through the user's nostrils. This arrangement ensures streamlined oxygen delivery into the system while maintaining structural compactness. The bent-up pipe (400) is designed with a small diameter to prevent carbon dioxide from passing back through the user's nose.

[0066] Regulation of the oxygen flow is achieved through the integrated action of the tee valve (200) and the exhalation valve (204), coordinated by the pressure- responsive behavior of the umbrella pin valve (500). During inhalation, back pressure generated by the user actuates the umbrella pin valve (500), enabling controlled oxygen flow through the ports (300) to the user's nostrils. In the event of excessive internal pressure, such as from over-delivery or user exhalation, the system is designed to vent surplus oxygen through the exit apertures (302) of the exhalation valve (204), thereby preventing oxygen saturation or delivery anomalies. Further, the device (100) incorporate pressure monitoring functionality within the tee valve (200), enabling real-time actuation of the umbrella pin valve (500) to maintain a consistent and safe flow rate aligned with the user’s ventilation minutes.

[0067] This design enables efficient, responsive oxygen delivery with built-in safety and pressure regulation mechanisms, making it particularly suitable for portable or continuous-use respiratory support systems.
