The STS is a handheld spirometer intended to measure lung function in adult patients while at rest (including spirometry and lung volumes). The STS is to be used by either a physician, respiratory therapist, or technician. {5}------------------------------------------------ | | STS Device | | |------------------------|--------------------|----------------| | Image: TechnoPulm logo | Traditional 510(k) | 510(k) Summary | The STS device is pulmonary function testing device that measures both flow/volume (spirometry), lung volume and resistance/compliance parameters. It is a multi-use device that should be used with a compatible single-use, disposable mouthpiece which incorporates a viralbacterial filter protecting the patient from the internal components of the device is battery operated allowing for approximately 40 operating hours between charges. The measurement results, which are transmitted via Bluetooth, are displayed on the physician's computer via the STS software/App. The STS has the following measurement capabilities: | Lung Volume Parameters: | | |-----------------------------------------------------------------------|-----------------| | Total lung capacity | (TLC) L | | Thoracic Gas Volume | (TGV) L | | Residual volume | (RV) L | | Ratio of TGV to TLC | (TGV/TLC) % | | Ratio of RV to TLC | (RV/TLC) % | | Flow/Volume (Spirometry) Parameters: | | | Forced vital capacity | (FVC) L | | Forced expiratory volume in 1second | (FEV 1) L | | Ratio of FEVI to FVC | (FEV1/FVC) % | | Forced expiratory volume in 6 seconds | (FEV6) L | | Forced expiratory volume in 3 seconds | (FEV3) L | | Ratio of FEV3 to FVC | (FEV3/FVC) % | | Peak expiratory flow | (PEF) L/s | | Forced expiratory flow between 25% and 75% of force vital capacity | (FEF 25-75) L/s | | Vital capacity | (VC) L | | Inspiratory vital capacity | (IVC) L | | Peak inspiratory flow | (PIF) L/s | | Resistance/Compliance Parameters: | | | Airway resistance | (RAW) kPa*s/L | | Lung compliance | (CL) L/kPa | #### 5. INDICATIONS FOR USE The STS device is intended to measure lung function in adult patients while at rest (including spirometry and lung volumes). The STS device is to be used by either a physician. respiratory therapist, or technician. The STS device is intended to be used in a professional healthcare environment. #### 6. SUBSTANTIAL EQUIVALENCE The STS is substantially equivalent to the predicate device based on the following: ### Intended Use The intended use of the proposed device is the same as that of the cleared device. The only difference in the indication for use statement is the narrowing of the STS population to include only adult patients. This difference is due to the fact that the STS device has not been tested in a {6}------------------------------------------------ | Image: Pi symbol | TechnoPulm | |------------------|------------| |------------------|------------| pediatric population. The narrowing of the indication does not raise new questions of safety and effectiveness. ## Technology Both the STS and Minibox are used to measure lung function in adult patients. Both devices are used with an off-the-shelf FDA cleared biological filter. The predicate is to be used with 2800 PFT FILTER by Air Safety Ltd. (K051712) and the STS can be used with MicroGard by CareFusion Germany 234 GmbH (K111408). In both devices, the test is performed by having the seated patient use a nose clip and blow through the mouthpiece filter. In both, the operator navigates through the software and is required to initiate the test prior to the patient exhaling in the device. In the STS, the patient is required to "blast" exhale into the mouthpiece; 3 successful tests are required in order to receive an output report. The Minibox procedure is slightly different; the patient first preforms 2-3 tidal breaths followed by "blast" exhale. In the Minibox, three tests are also required in order to obtain comprehensive results. Both devices require a relatively short procedure duration (approximately 15 minutes to perform 3 successful breath tests). With respect to device design, the Minibox is a standalone unit incorporating the handheld device which is wired to the desktop unit. The desktop unit incorporates a touch screen that allows for software navigation to operate the system, control the test, input patient data, commence testing, etc. When compared to predicate, the STS is more compact and connects via Bluetooth to the user's PC on which the STS software is installed. Additionally, while the majority of lung test parameters are the same between the two devices, some parameters are only available on one device and not the other, this difference does not raise new safety and effectiveness concerns as the obtained parameters for both devices are sufficient to perform a lung function assessment. {7}------------------------------------------------ | Attribute | Subject Device | Primary Predicate | Reference Device | Comparison | |------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------| | Trade Name | STS | MiniBox + | Resmon PRO FULL | | | 510(k) Number | K240293 | K161295 | K152585 | | | Classification | Class II, BZC, BZG | Class II, BZC, BZG | Class II, PNV, BZC | Same as primary predicate | | Regulation | Calculator, Pulmonary Function Data | Calculator, Pulmonary Function Data | Diagnostic spirometer | Same as primary predicate | | Description | | | | | | Regulation Number | 868.1880 - Pulmonary-function data calculator | 868.1880 - Pulmonary-function data calculator | 868.1840 - Diagnostic spirometer | Same as primary predicate | | Classification Panel | Anesthesiology | Anesthesiology | Anesthesiology | Same | | Indications For Use | The STS is intended to measure lung function in adult patients while at rest (including spirometry and lung volumes).

The results of the bench testing support the safety profile of the device and demonstrate that the device functions as intended. ## Clinical Study: The main goal of the study was to evaluate the performance of STS technique in calculating resistance and compliance parameters. The accuracy of the STS device was examined by comparing with Body plethysmography (BP), which is considered as the "gold standard" for measuring lung volumes. 161 subjects including 61 females enrolled in the study, to be tested by both STS and BP. The subject population included 63 healthy subjects (39.1%), 40 (24.9%) obstructive patients and 58 (36.0%) restrictive patients. The age of enrolled subjects was 53.5±31.5 years. The comparison results demonstrated a high correlation between the two devices. Correlation coefficients were in the range between 0.75 and 0.97, the P-value did not exceed 3%, repeatability coefficients were less than 0.3L and within-subject standard deviation values were less than 0.15L. #### 9. CONCLUSION The STS has similar intended use, technological characteristics, and principles of operation as the predicate. Any differences between the subject and predicate device were evaluated through design verification and validation testing and comparative testing which demonstrated device performance and safety, and do not raise any new questions of safety and effectiveness. Based on the information submitted in this 510(k), the STS is substantially equivalent to the currently marketed predicate Minibox+.
