Intended Use

The NPB-500 Spirometry System's intended use is simple diagnostic forced vital capacity (FVC) testing for adults of all ages plus pediatric patients, in the patient examination rooms of a physician's practice and in hospital-type facilities such as respiratory care centers. The NPB 500 Spirometry System is for prescription use only.

Device Description

The NPB-500 Spirometry System comprises the following five components, including accessories: NPB-500 Spirometer (hand held), Flow Sensor II, Pressure Tubing, NPB-510 Spirometer Base (optional) and Printer/PC Cable (optional). Two versions of the cable are available, namely, a parallel cable for a Printer and a serial cable for a PC. The NPB-500 is a hand held diagnostic Spirometer intended for patient use in the performance of Forced Vital Capacity, FVC, testing. The patient performing a test is requested to take a deep breath and then exhale vigorously and continuously into the sensor's mouthpiece until complete exhalation is achieved. Initially, the testing process requires patient cooperation and supervisory coaching to achieve optimum results. FVC parameter test results may be displayed on the Spirometer's front face LCD display. Alternatively, the Spirometer can be inserted into the optional Spirometer Base, enabling data to be interfaced, via an output data port, to a parallel printer for graphical printout of the patient's test record, or to a PC. In addition to the above mentioned device features, the instrument has been designed to satisfy the needs of both the user and the patient. An audible, mid frequency, beep tone is provided to prompt the User for input, inform the User of the successful completion of a process step or warn of low battery condition. The NPB-500 System is powered by two AA size standard alkaline batteries which can provide an estimated operating time of six months under normal use.

Not Found

AI/ML (Artificial Intelligence / Machine Learning)

No
The description focuses on basic spirometry measurements, data display, and printing/PC interfacing. There is no mention of AI/ML terms, image processing, or any complex data analysis that would typically involve these technologies. The performance studies are described as "in-vitro testing to confirm accuracy," which is standard for this type of device and does not suggest AI/ML.

Therapeutic

No
The device is described as a "diagnostic" spirometer used for "testing" FVC, not for treating or preventing a disease or condition.

Diagnostic

Yes
The "Intended Use / Indications for Use" section explicitly states that the device's intended use is "simple diagnostic forced vital capacity (FVC) testing." Additionally, the "Device Description" refers to it as a "hand held diagnostic Spirometer."

SaMD (Software as a Medical Device)

The device description explicitly lists multiple hardware components, including a hand-held spirometer, flow sensor, pressure tubing, and optional base and cables.

IVD (In Vitro Diagnostic)

Based on the provided information, the NPB-500 Spirometry System is not an In Vitro Diagnostic (IVD).

Here's why:

IVD Definition: In Vitro Diagnostics are medical devices intended to be used in vitro for the examination of specimens, including blood and tissue samples, derived from the human body, solely or principally for the purpose of providing information concerning a physiological or pathological state, or concerning a congenital abnormality, or to monitor therapeutic measures.
NPB-500 Function: The NPB-500 Spirometry System measures lung function by having the patient exhale directly into a sensor. It does not analyze biological specimens (like blood, urine, or tissue) in a laboratory setting.
Intended Use: The intended use clearly states "simple diagnostic forced vital capacity (FVC) testing for adults of all ages plus pediatric patients, in the patient examination rooms of a physician's practice and in hospital-type facilities". This describes a direct physiological measurement performed on the patient, not an analysis of a specimen.
Device Description: The description details a hand-held device with a flow sensor and tubing, designed for direct patient interaction during exhalation.

Therefore, the NPB-500 Spirometry System falls under the category of a diagnostic medical device that performs a physiological measurement, rather than an In Vitro Diagnostic device that analyzes biological specimens.

Device Description

The NPB-500 is a hand held diagnostic Spirometer intended for patient use in the performance of Forced Vital Capacity, FVC, testing. The patient performing a test is requested to take a deep breath and then exhale vigorously and continuously into the sensor's mouthpiece until complete exhalation is achieved. Initially, the testing process requires patient cooperation and supervisory coaching to achieve optimum results.

FVC parameter test results may be displayed on the Spirometer's front face LCD display. Alternatively, the Spirometer can be inserted into the optional Spirometer Base, enabling data to be interfaced, via an output data port, to a parallel printer for graphical printout of the patient's test record, or to a PC.

In addition to the above mentioned device features, the instrument has been designed to satisfy the needs of both the user and the patient. An audible, mid frequency, beep tone is provided to prompt the User for input, inform the User of the successful completion of a process step or warn of low battery condition. The NPB-500 System is powered by two AA size standard alkaline batteries which can provide an estimated operating time of six months under normal use.

A pneumotachometer sensor is used to convert the expired breath flow signal into a pressure signal. The NPB-500 Spirometry System measures the values of FVC parameters by continuously sensing this pressure throughout an expired breath. This signal is pneumatically coupled to a pressure transducer in the NPB-500 Spirometer to develop corresponding electrical data. Conventional electronics and embedded software are used to process this data and generate numerical values of FVC parameters for presentation on the NPB-500's LCD display. Alternatively, graphical test results may be recorded on a printer.
