[0001] Cross-Reference to Related Applications This application claims the benefit of priority under 35 U.S.C. §119 of U.S. Provisional Patent Application No. 63 / 581,691, filed on September 11, 2023, entitled "INCENTIVE SPIROMETER DEVICE, SYSTEM, AND METHOD", which is expressly incorporated herein by reference in its entirety.

[0002] Technical Field The present disclosure describes systems, devices, and methods for spirometry, such as incentive spirometry systems and methods. The systems, devices, and methods described herein facilitate patient interaction, consistent use, and tracking of patient progress and quantifiable outcomes.

Background Art

[0003] Incentive spirometers can be used to help users improve lung function by strengthening the lungs and promoting lung expansion. Incentive spirometry is utilized for patients who have undergone any surgery that may affect respiratory function, including surgery on the lungs, cardiac surgery, or other surgeries that may involve prolonged in-bed recovery.

[0004] While diagnostic spirometers can measure the volume of air exhaled from the lungs, incentive spirometers measure the volume of air inhaled into the lungs during inspiration. Volume-oriented devices measure the volume of inspired air, while flow-oriented devices measure the flow rate of inspired air. Incentive spirometers may include a target respiratory volume that is manually set (e.g., via a slide) by a healthcare practitioner.

Summary of the Invention

[0005] This disclosure describes systems, devices, and methods for spirometry, including incentive-based spirometry systems.

In certain implementations, the systems, devices, and methods described herein may include an airflow assembly having a pressure sensor that facilitates the acquisition of sensor data from multiple inspiratory repetitions (e.g., when the patient or user interacts with the mouthpiece).

[0006] While incentive spirometry has been shown to reduce the risk of postoperative pulmonary complications, shorten hospital stays, and lower readmission rates, numerous drawbacks hinder its potential benefits, including patient adherence issues and significant monitoring requirements that place a time burden on healthcare professionals.

[0016] The same reference numeral in various drawings indicates the same element. [Modes for carrying out the invention]

[0017] Detailed explanation Figure 1 shows an embodiment of the incentive spirometry system 100, including the incentive spirometry device 102. The incentive spirometry system 100 includes the incentive spirometry device 102, a user device 104, and a provider device 106. Generally, the incentive spirometry device 102 may capture data to capture, analyze, and evaluate the user's inhalation performance when the user interfaces with the mouthpiece 110 of the incentive spirometry device 102, for example, using sensors. Analysis and evaluation may include identifying performance parameters such as repetitions, volume, airflow, and adherence to the treatment protocol, among other indicators. The incentive spirometry system 100 may be used to improve a patient's lung function, strengthen the lungs, and promote lung expansion. For example, some embodiments of the incentive spirometry system 100 and the incentive spirometry device 102 may be implemented to improve a patient's lung function, strengthen the lungs, and promote lung expansion in a patient's post-surgical recovery. Some examples of such surgeries include, but are not limited to, spinal surgery, abdominal surgery, and hip / knee replacement, colectomy of both the small and large intestines, as well as some non-surgical pediatric and non-pediatric indications such as sickle cell anemia and long-term COVID-19, which are indications for incentive spirometry, as these have the highest morbidity and incidence of postoperative pulmonary complications.

[0018] The incentive spirometry system 100 facilitates data communication (e.g., using wireless or wired signals) between the entire system and between each of the incentive spirometry device 102, user device 104, and provider device 106. In some embodiments, the incentive spirometry device 102, user device 104, and provider device 106 can communicate with each other. For example, the incentive spirometry device 102 can communicate sensor data acquired during one or more user iterations to either or both of the user device 104 and / or the provider device 106. In some embodiments, the incentive spirometry device 102 can communicate sensor data (e.g., including one or more inhalation signatures) to the user device 104, and the user device 104 can communicate sensor data (e.g., including one or more inhalation signatures) to the provider device 106. In some embodiments, the incentive spirometry device 102 may transmit sensor data to both the user device 104 and the provider device 106.

[0019] The incentive spirometry device 102 can facilitate a user (e.g., a patient) performing repetitions, including inhaling air into the user's lungs through the incentive spirometry device 102. For example, a patient may position their mouth over the mouthpiece 110 and inhale air into their lungs. The incentive spirometry device 102 directs the air through the air inlet 130 of the airflow assembly 112, through at least one sensor, and towards the patient from the mouthpiece 110. As will be described in more detail below, the incentive spirometry device 102 may include at least one sensor that records sensor data throughout each of the user's repetitions. The sensor data may include airflow rate, volume, pressure, and other data for each repetition. An inspiratory signature is generated for each repetition to reflect the results of each repetition.

[0020] The user device 104 may be the user's personal device (e.g., a patient device). Non-limiting examples of the user device 104 include a smartphone, wearable device, tablet, laptop, computer, external display, or other user device. The user device 104 may communicate (e.g., wired or wirelessly) with the incentive spirometry device 102 and the provider device 106. The user device 104 may display various parameters and controls related to the incentive spirometry device 102, as described in detail below. In some embodiments, the user device 104 may display sensor data to the user before, during, and after the user interfaces with the incentive spirometry device 102 and performs repetitions. For example, the user device 104 may simultaneously display one or more inspiratory signatures to the user while the user is using the incentive spirometry device 102. Simultaneous display of inspiratory signatures (e.g., generated based on sensor data) can facilitate the real-time display of results to the user and improve the user experience. For example, real-time display can encourage patient performance when the patient sees volume measurements below the target, prescribed, or recommended volume measurements for each repetition. This can facilitate and gamify user interaction with the incentive spirometry device 102 to promote improved adherence, performance, and patient outcomes.

[0021] The provider device 106 may be a device controlled by and / or accessible to a physician or other healthcare professional. Non-exclusive examples of the provider device 106 may include a smartphone, wearable device, tablet, laptop, computer, external display, or other provider device. The provider device 106 may communicate (e.g., wired or wirelessly) with the incentive spirometry device 102 and the user device 104. The provider device 106 facilitates the communication of one or more treatment protocols to the user device 104 and / or the incentive spirometry device 102. Treatment protocols may be prescribed, recommended, or otherwise transmitted from the provider device to the user device 104 and / or the incentive spirometry device 102. The user device 104 may remind or encourage the user to perform iterations with the incentive spirometry device 102 by displaying one or more notifications or alerts to the user in accordance with the treatment plan. In some embodiments, repetitions performed by the incentive spirometry device 102 may be recorded according to a treatment protocol received from the provider device 106. Furthermore, the inspiratory signatures logged in the treatment protocol may be transmitted to both the user device 104 and the provider device 106.

[0022] Figure 2 shows an exploded view of the incentive spirometry device 102. The incentive spirometry device 102 includes a mouthpiece 110, an airflow assembly 112 including an airflow insert 114 and an airflow housing 116, a housing 118 including a display 120 and a button 122, a shroud 124, a switch panel 126, and a rear housing 128. In some embodiments, the airflow assembly 112 and mouthpiece 110 may be disposable components that can be used by a single patient (for example, for one or more treatment sessions, which may include multiple repetitions per treatment session). For example, the airflow assembly 112 and mouthpiece 110 may be connected to and disconnected from the housing 118 for rapid assembly and disassembly of the incentive spirometry device 102. In some embodiments, the housing 118, shroud 124, switch panel 126, and / or rear housing 128 may be reusable components.

[0023] Referring to Figures 2-9, the airflow assembly 112 may include an airflow insert 114 that can be received within the airflow housing 116. The airflow assembly 112 includes a first end 132 configured to connect to the housing 118. For example, the first end 132 may include a female connector that interfaces with one or more male connectors on the housing 118. In some embodiments, the first end 132 may connect to the housing 118 via mechanical prongs or press-fit connections that allow for easy connection and disconnection of the components. In some embodiments, the first end 132 may connect to the housing 118 via a magnetic connection. The airflow assembly 112 may include a second end 134 located on the opposite side of the first end 132. The second end 134 may be configured to connect to the mouthpiece 110. For example, the second end 134 may include a male connector that can be received within the mouthpiece 110 to facilitate connection between them.

[0024] The airflow assembly 112 includes an air inlet 130 and an air outlet 136. The air inlet 130 may be located within the upper surface of the airflow assembly 112 and may also introduce air into the airflow chamber 138 (see, for example, the flow pattern 140 shown in Figure 5). For example, when a patient inhales through a mouth positioned around the mouthpiece 110 (and the mouthpiece 110 connected to the airflow assembly 112), air is drawn into the airflow chamber 138 through the air inlet 130. In some embodiments, the air inlet 130 includes one or more laser-cut characters defining multiple openings through the airflow housing 116 for connection to the airflow chamber 138.

[0025] The airflow chamber 138 may extend into the mouthpiece 110 from the inlet 130 to the second end 134 through the airflow assembly 112. The airflow chamber 138 may be a Venturi flow chamber having an inlet portion 142, a constricted portion 144, and an outlet portion 146. The constricted portion 144 may have a constriction diameter D2 smaller than the diameters D1 of the inlet portion 142 and the outlet portion 146. In some embodiments, the diameters D1 of the inlet portion 142 and the outlet portion 146 may be the same. In other embodiments, the diameter D1 of the inlet portion 142 may be larger than both the diameters D2 of the constriction portion and the diameter D3 of the outlet portion. In other embodiments, the diameter D3 of the outlet portion may be larger than both the diameters D2 of the constriction portion and the diameter D1 of the inlet portion. The inlet portion 142 may include a tapered region 142a, and the outlet portion 146 may include a tapered region 146a that gradually narrows the diameter of the airflow chamber 138 toward the constricted portion 144.

[0026] The constricted portion may include a lateral opening 149 and a sensor 150 within the lateral opening 149. The sensor 150 may be positioned at or near the center of the constricted portion 144. The sensor 150 can seal the lateral opening 149 and maintain an airtight airflow chamber 138 between the inlet 130 and the outlet. The lateral opening 149 may have diameters of 0.5–5 mm, 1–4 mm, 2–3 mm, and about 2.5 mm. In some embodiments, the sensor 150 is configured to collect sensor data from the constricted region 144. For example, the sensor 150 may collect data such as airflow velocity, pressure, volume (e.g., flow rate), temperature, and humidity, among other data. In some embodiments, the sensor 150 may be an absolute pressure sensor, an accelerometer, an impeller sensor, a turbine flow meter, a flow meter, a thermal sensor, a differential pressure sensor, or a magnetic induction sensor, among other sensors.

[0027] Referencing Figures 6-9, embodiments of the airflow insert 114 are shown. Figures 6 and 7 show the airflow insert 114 having an L-shaped inlet 130. Figures 8 and 9 show the airflow insert having a T-shaped inlet 130b. For example, the L-shaped inlet 130 contributes to increasing the stability of the calculated air pressure difference (e.g., pressure at the constricted portion 144 versus pressure between the constricted portion 144 and the inlet 130) because the inlet 130 faces perpendicular to the airflow channel 138 from which the sensor 150 samples. Laser-cut characters on the inlet 130 and through the housing 116 also make it more difficult for the user to (i) place a mouth or any other air-generating device covering the character opening to produce false inhalation records, or (ii) accidentally cover the inlet while holding a device and be unable to produce measurements. In some embodiments, the T-shaped inlet 130b further stabilizes the air pressure measurement by making it much more difficult to generate any airflow passing through the sensor 150 other than inhalation at the mouthpiece 110. Any blowing at the laser-cut letters (e.g., inlet 130b) passes through the short end of the T-shaped inlet 130b and does not obstruct the airflow along the tube having the sensor 150. The additional holes also make it more difficult for the user to accidentally cover the airflow opening when using the device 102. Furthermore, the L-shaped inlet 130 and the T-shaped inlet 130b can provide different levels of resistance to the user's inhalation. Different levels of resistance may be implemented in the treatment protocol as the patient progresses, or even used for different patients at different stages of recovery. In each of the L-shaped inlet 130 and the T-shaped inlet 130b, the inlets 130, 130b, and outlet 136 are not parallel to each other. In some embodiments, the inlets 130, 130b, and outlet 136 are perpendicular to each other. In some embodiments, the inlets 130, 130b, and outlets 136 are perpendicular to each other in a plurality of outlet openings. In some embodiments, the inlets 130, 130b, and outlets 136 are arranged in a non-parallel configuration between parallel and perpendicular (e.g., at any angle from 1 to 89 degrees).

[0028] Figures 6 and 8 show exemplary dimensions (mm) of various components of the airflow insert 114 shown in Figures 2 to 9. For example, the constricted portion 144 (e.g., diameter D2) may be 1 to 10 mm, 2 to 8 mm, 3 to 5 mm, or about 4 mm. The constricted portion 144 may have a length of 10 to 30 mm, or about 20 mm. The inlet portion 142 and outlet portion 146 may have diameters of 8 to 20 mm, 10 to 17 mm, 12 to 15 mm, or about 14 mm. The lateral opening 149 may have a diameter of 0.1 to 5 mm, or about 2.6 mm. These dimensions are non-limiting and are shown as exemplary dimensions that may be implemented in some embodiments of the airflow insert 114. Other embodiments may include different dimensions.

[0029] Referring to Figure 2 and 10A-F, the mouthpiece 110 is configured to connect to the second end 134 of the airflow assembly 112. The mouthpiece 110 may be configured to interface with the user's mouth. For example, the user may position their lips around the outlet end 160 of the mouthpiece during repetitions with the inspiratory spirometry device 102. The mouthpiece 110 may allow air from the air inlet 130, through the airflow chamber 138, from the airflow insert 114, through the airflow chamber 138, into the mouthpiece 110, and into communication with the user. The mouthpiece 110 may include a one-way valve 162 that allows airflow from the mouthpiece inlet 164, connected to the second end 134 of the airflow assembly 112, to the outlet end 160 on the opposite side of the mouthpiece inlet 164.

[0030] Figure 10F shows exemplary dimensions (mm) of various components of the mouthpiece 110. For example, the mouthpiece inlet 164 may have a width of 10–20 mm, 11–15 mm, or about 13 mm. The mouthpiece outlet end 160 may have an internal opening of 4–15 mm, 5–12 mm, or about 7 mm. The mouthpiece outlet end 160 may have an external dimension of 5–20 mm, 7–13 mm, or about 10 mm. These dimensions are non-limiting and are shown as exemplary dimensions that may be implemented in some embodiments of the mouthpiece 110. Other embodiments may include different dimensions.

[0031] Figure 11A shows an exemplary calibration connector 170. The calibration connector 170 may be connected to the airflow assembly 112 and the inspiratory spirometry device 102 in the same position as the mouthpiece 110. For example, the mouthpiece 110 may be removable and the calibration connector 170 may be connected to the airflow assembly 112. The calibration connector 170 may be connected as an adapter so that the inspiratory spirometry device 102 can be calibrated before or after use. For example, the calibration connector 170 may facilitate connection to a syringe for testing and calibration, as shown in Figures 11B-C.

[0032] Figure 11B shows exemplary test results 171 consistent with several embodiments of the present disclosure. In some embodiments, test results 171 may represent a test and verification of the effectiveness of the incentive spirometry system 100 and the incentive spirometry device 102. Test results 171 confirmed that the incentive spirometry system 100 and the incentive spirometry device 102 accurately measure lung volume in accordance with the ISO 26782 standard. Specifically, the ISO 26782 standard specifies a maximum permissible error of 75 mL for a 3 L syringe. The devices were tested using 3 L ISO certified syringes to simulate various respiratory volumes, with particular focus on evaluating the accuracy of the measurements. The main focus of the test protocol was the reproducibility of the device measurements. To evaluate accuracy, a known 3L volume was aspirated via a syringe through a spirometer for a total of 12 samples at three different airflow rates (200 mL / sec, 400 mL / sec, and 600 mL / sec). The volume recorded by the spirometer was recorded for analysis. The order of each test with different target flow rates was randomized. The volumes recorded from the spirometer can be seen in Table 1 below. The mean of these measurements was 3.009L, and the 99% confidence interval was calculated to be 2.956L to 3.063L, which falls within the maximum acceptable range of 2.925L to 3.075L. Table 2 shows the mean and standard deviation across different target flow rates. As shown in Table 3, no significant differences were found in the measurements between the different flow rates. [Table 1] [Table 2] [Table 3]

[0033] The results of the statistical analysis show that the incentive spirometry system 100 and incentive spirometry device 102 demonstrate a high level of accuracy and consistency in measuring lung volume. The mean volume of 3.009 L is close to the expected 3 L, with minimal deviation. The accuracy of the incentive spirometry system 100 and incentive spirometry device 102 suggests reliability in repeated use in measuring lung volume, which is advantageous for both clinical settings and patient self-monitoring. No significant discrepancies were observed, and the performance of the incentive spirometry system 100 and incentive spirometry device 102 meets the accuracy criteria outlined in ISO 26782.

[0034] Regarding Figure 11B, test result 171 also includes the following: TIFF2026534039000005.tif105128

[0035] Figure 11C shows an exemplary calibration process 172. Experimental flow rate indicates the flow rate value output by the device. Actual flow rate refers to the true flow rate obtained by pulling the syringe within a certain time period. The exemplary results show a slightly better fit at lower flow rates than at higher flow rates, which may be advantageous in patients using the inspiratory spirometry device 102, as they typically have limited lung function. The overall RMSE is 18.6 mL / sec and the R-squared value is 0.985, suggesting a very accurate system with much higher precision than standard treatment.

[0036] A model of a patient's lung was generated to verify that the inventor's design could effectively measure lung capacity and flow rate. Calibration and test process 171 may involve using a 500 mL syringe with a scale connected to a Venturi tube via a tube. The end closest to the "lung" (corresponding to the patient's mouth) is airtightly sealed with a stopper, while the other end of the Venturi tube is left open to the air. To collect data to serve as a control, an Arduino circuit was constructed with a timer started / stopped by a button press. When weight was applied to the syringe handle, the plunger was pulled down at a constant speed using the button press, and measurements of the airflow velocity and volume of the "breath" were recorded. A pressure sensor located in the constricted part could measure changes in pressure and convert them into flow rate and vital capacity calculations (experimental data). After conducting multiple tests, linear regression of experimental flow values ​​against the control group yielded a slope of 0.999 and an R² of 0.989, suggesting that the design can be used to accurately measure flow and calculate vital capacity.

[0037] Figure 12 shows a switch panel 126 according to several embodiments. The switch panel 126 may include, among other features, one or more processors or engines, a memory storage device, a power supply, and a wireless transmitter. The switch panel 126 may facilitate wireless communication with the user device 104 and / or the provider device 106. The switch panel 126 may also store instructions (e.g., treatment protocols, operation commands, or other instructions) that facilitate the operation of the inspiratory spirometry device 102 and the inspiratory spirometry system 100. The switch panel 126 may include one or more power supplies (e.g., batteries such as rechargeable batteries) that power the inspiratory spirometry device 102. In some embodiments, the connection between the rear housing 128 and the switch panel 126 allows clinicians / healthcare workers to access and use the switch panel 126 and, if necessary, conceal it from the patient. The switch panel 126 may include switches for turning off exercise reminders (for example, the device beeping and vibrating every X minutes to remind the patient to complete the exercise), resetting the microcontroller, and turning the power on / off.

[0038] Referring to Figures 2 and 13, the housing 118 includes a display screen 120, buttons 122, a power supply 181, one or more processors 182 (or engines), and one or more storage devices. Airflow through the incentive spirometry device 102 may be prevented from entering the housing 118 based on the connection of the airflow assembly 112 to the housing 118. The airflow assembly 112 may facilitate the airflow path while the housing 118 may be closed off from the airflow path. The housing 118 may be reusable, and sterilization of the housing 118 may not be necessary. In some embodiments, the airflow assembly 112 may be sterilized, and the housing 118 may be cleaned (and may not require sterilization due to lack of airflow). The housing 118 may be reusable. The housing 118 includes an electrical port 183 via an interface 132 with the first end of the airflow assembly 112. For example, the first end 132 of the airflow assembly 112 may include one or more electrical contacts to facilitate connection of the sensor 150 to the electrical components of the housing 118. In some embodiments, a switch panel 126 is integrated into the housing 118. Button 122 may be a power button and / or a start / stop button that allows the user to turn on the inspiratory spirometry device 102 and start / stop repetitions and / or exercise sessions.

[0039] Figure 14 shows an exemplary schematic diagram of the electrical assembly 190 of the inspiratory spirometry system 100. In some embodiments, the electrical assembly 190 may be housed within the inspiratory spirometry device 102. Each component may be connected to a microcontroller 182 (or another preferred processor programmed with code stored on a non-temporary computer-readable medium, the execution of which carries out the operation of the device). Additional electronics, including an LED, a vibration motor 185 for tactile feedback, a memory 189 (e.g., optionally including an SD reader), and / or a speaker 187, which may be used to remind the patient when to perform exercises, read what is on an electronic screen, and / or otherwise interact with the patient, may also be incorporated into the body of the device.

[0040] Figure 15 shows an exemplary embodiment of data transmission from a microcontroller 182 (e.g., inspiratory spirometry device 102) to a user device 104 and / or one or more databases or other storage media. Pressure data collected by the pressure sensor 150 is calculated into volume and flow rate data within the microcontroller 182 and transmitted to the user device 104 (e.g., a smartphone, tablet, or an application residing on another device) using the MQTT messaging protocol. The application may then use the HTTP protocol to send some or all of the collected data, in particular the flow rate and volume during measurement and the time of measurement, to a cloud-based database. The mobile app refers to the cloud-based database when displaying the patient's previously recorded exercise data. In embodiments, data may be transmitted directly from the incentive spirometry device to the cloud-based database. In embodiments, the collected data is automatically transmitted for inclusion in the patient's electronic medical record.

[0041] Figures 16-19 show an exemplary user interface 200 on the user device 104. For example, the user interface 200 may reflect various screens of a companion application stored and accessible on the user device 104 and the provider device 106. The user interface 200 facilitates the control, tracking, and display of results from the inspiratory spirometry system 100. For example, the user interface 200 may facilitate the initiation of an exercise session (e.g., one or more repetitions on the inspiratory spirometry device 102). The interface 200 may display the inspiratory signature in real time on the user device 104 while the user performs repetitions on the inspiratory spirometry device 102. The interface 200 may display progress reports, exercise history, metrics for current or past repetitions, and a treatment protocol including schedule, time, and goals.

[0042] Figures 20 and 21 show an exemplary user interface 202 in the provider device 106. Interface 202 can display results for one or more patients using one or more inspiratory spirometry devices 102. User interface 202 may be configured to manage connections with each patient and / or inspiratory spirometry device. For example, interface 202 may facilitate the programming or prescription of treatment protocols for one or more patients. Treatment protocols may include, among other parameters, the number of repetitions, the volume per repetition, and the treatment schedule.

[0043] Figures 22-24 show an exemplary user interface 204 on the user device 104. Similar to user interface 200, user interface 204 facilitates user interaction and control with the inspiratory spirometry device 102. Some embodiments of user interface 204 may include simultaneously displaying the results of the user performing one or more repetitions using the inspiratory spirometry device 102. For example, interface 204 may gamify the user experience by displaying motivational icons and graphics to encourage the user to perform repetitions or to increase the effort spent on each repetition. For example, a rocket icon may be displayed to encourage the user to put more effort into their repetitions. The greater the inhalation volume, the higher the rocket icon rises on the screen, thereby rewarding the user during the exercise. In another non-limiting example, interfaces 200, 204 may include gamification in which the user collects medals / trophies when they achieve target goals or target inhalation counts / repetitions for their exercise.

[0044] In some embodiments, gamification and guidance provided on interfaces 200, 204 may be provided as visual, auditory, and tactile cues both via an app (e.g., via interfaces 200, 204) and on the device itself (e.g., on display 120). Guided exercises (with or without gamification) facilitate improved patient outcomes by effectively coaching and training patients to a desired specific inhalation rate range that many patients fail to adhere to. For example, a patient may try to breathe as fast as possible to reach a target (>1200 ml / sec), and the interfaces, guidance, and gamification approaches described herein facilitate adherence to beneficial rates such as 200-800 ml / sec. The systems, devices, and methods described herein provide guidance and cues (e.g., via display 120 and / or an application via interfaces 200, 204 and user device 104) based on real-time flow measurements (e.g., "breathe slower").

[0045] Figures 25A-B show another exemplary incentive spirometry system 2500. The incentive spirometry system 2500 may share features with the incentive spirometry system 100 described above. The incentive spirometry system 2500 may include an incentive spirometry device 2502, which includes (1) a removable and disposable mouthpiece 2510 in which the user places their mouth; (2) a removable and disposable Venturi tube insert 2512 that functions as the main airflow channel within the device; (3) a lid 2524 having an on / off push button; and (4) a device body 2518 housing all electronic components, including but not limited to a pressure sensor 2550 and a digital display screen 2520. When a patient inhales from the assembled device to perform an incentivized spirometry exercise, a pressure sensor housed within the main body and operably coupled to the Venturi tube insert receives the pressure reading in the tube insert and derives the airflow velocity and inhalation volume.

[0046] Figure 26 shows the airflow insert 2512 of the incentive spirometry system 2500. The airflow insert 2512 may share features with the airflow assembly 112 described above (e.g., including an air chamber, pressure sensor, etc.).

[0047] Figure 27 shows the mouthpiece 2510. The mouthpiece 2510 may share features with the mouthpiece 110 described above. For example, the mouthpiece 2510 may be attached to a one-way valve before being inserted into the incentive spirometry device 2502 to prevent excess moisture from entering the airflow insert 2512. In embodiments, the valve is a one-way valve located within the mouthpiece 2510 itself so that the mouthpiece can stand on its own as a one-way mouthpiece. The airflow flows from the narrow end to the wide end of the mouthpiece as the patient inhales.

[0048] Figure 28 shows the main body 2518 of the incentive spirometry device 2502. The main body 2518 may share features with the housing 118. The main body 2518 may house electronic components including (1) a pressure sensor, (2) a digital screen, (3) a microcontroller or engine (or other preferred processor), and (4) a push button coupled to the lid of the main body. An airflow tube is inserted into a rectangular opening on the side of the main body, with openings at opposite ends for air to pass through and flow. There are also openings for the digital screen and a USB-C charging port.

[0049] Inhalation volume and flow rate measurements are collected by digital pressure sensors in the airflow tube (e.g., sensors 150, 2550) and may be displayed on the device screen. Alternatively, or additionally, in embodiments, volume and flow rate measurement data are wirelessly relayed to a companion iOS (or Android®, or other) mobile app via WiFi, Bluetooth®, NFC, or other wireless communication technologies and protocols. Naturally, in embodiments, this data may be transmitted via a wired connection. The paired app (e.g., user device 104) has the ability to enhance patient compliance and provide easily accessible compliance data to the clinician (e.g., provider device 106). The patient side of the app includes tutorials on how to perform exercises, exercise reminders and notifications, a measurement view that displays guidance during exercise, a view that allows the patient to track exercise completion progress over time, and gamified exercise games. The clinician side of the app displays a summary of all of the patient's exercise performance and compliance and alerts patients who are not complying or whose exercise performance has declined.

[0050] Examples of Descriptions Incentive spirometry systems 100, 2500, and incentive spirometry devices 102, 2502 can utilize a microcontroller (e.g., processor 182, and / or engine) having the pinouts shown below to acquire readings from differential pressure sensors (e.g., sensors 150, 2550) and simultaneously convert them into flow rate and vital capacity measurements. In some embodiments, if the constriction is open to the chamber and the pressure in the constriction is measured using the aforementioned pressure sensors, the initial pressure is set to 1 atmosphere. The velocity of the airflow in the constriction facilitates the calculation of flow rate, which can then be integrated to calculate the volume of inhaled air, or vital capacity.

[0051] variable: Points 1 and 2 are located along the same streamline, inside and outside the constriction within the Venturi tube. TIFF2026534039000006.tif41128TIFF2026534039000007.tif92128

[0052] The systems, devices, and methods described herein are advantageous in that they facilitate at least hygienic reusability, digital integration, customizable parameters, remote monitoring, and data analysis and research. For example, the removable airflow assemblies 112, 2512 facilitate easy disinfection or replacement, maintaining a higher level of hygiene between patients. The design of the removable airflow tubes also simplifies cleaning and maintenance processes, reducing the burden on healthcare workers. By incorporating digital technology within the incentive spirometry systems 100, 2500, it is advantageous that real-time data tracking, patient progress monitoring, and integration into electronic health record (EHR) systems are facilitated. This can enhance patient care and streamline data management. The digital nature of the incentive spirometry systems 100, 2500 allows for customizable parameters based on individual patient needs or prescribed rehabilitation plans. This adaptability improves the accuracy and effectiveness of treatment. The systems, devices, and methods described herein facilitate the analysis of patient trends in vital capacity and other clinical and patient background factors, allowing for better prediction of which patients are at highest risk of PPC and even prediction of PPC occurrence before it occurs. Various factors (smoking status, incision size, duration of anesthesia, BMI, pre-surgical vital capacity) can be used for prediction, and the system (e.g., via user device 104 and provider device 106) can incorporate this data into sensor data. The digital interface of the incentive spirometry systems 100, 2500 provides visual feedback and interactive elements to enhance patient engagement and motivation during respiratory exercises, leading to improved patient adherence and better outcomes. The digital data transmission function allows healthcare professionals to remotely monitor patient progress and adherence to prescribed spirometry exercises. This function is further beneficial for telemedicine and remote patient management when inpatients are discharged from the hospital.The digital capabilities of this device facilitate research by promoting the collection of standardized and consistent spirometry data across different patient populations. Digital spirometers collect and analyze data over time, providing insights into patient trends and progress. This enables clinicians to make informed decisions and develop personalized treatment plans or interventions for complications. Reuse across patients and avoidance of disposable components can also lead to cost savings over time.

[0053] Furthermore, several embodiments described in more detail below can facilitate the efficient and informed allocation of medical resources, personnel, treatments, and time in clinical and non-clinical settings. For example, the systems, devices, and methods described herein can facilitate the efficient allocation of medical staff (e.g., nurses, physicians, therapists, etc.) responsible for identifying patients at highest risk of postoperative pulmonary complications (PPC) and ensuring patient adherence to treatment protocols.
