The summary describes a standard spirometer measuring basic respiratory parameters and transferring data for historical tracking. There is no mention of AI/ML algorithms for analysis, interpretation, or prediction.
No
The device is intended to monitor specific lung function parameters (PEF, FEV1, FEV6) and track historical data, which are diagnostic and monitoring functions, not therapeutic.
Yes
The device description and intended use indicate that it measures parameters of lung function (PEF, FEV1, FEV6) which are used in the diagnosis and monitoring of respiratory conditions.
No
The device description explicitly states it is a "portable and handheld electronic spirometer" and mentions "TD-7301 Spirometer hardware". It also describes transferring data via Bluetooth, implying a physical hardware component. While it includes software (iFORA smart app and embedded software), it is not solely software.
Based on the provided information, the TD-7301 Spirometer is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use is to "monitor Peak Expiratory Flow (PEF), Forced Expiratory Volume (FEV) in home and professional healthcare environments." This involves measuring physiological parameters directly from the patient's respiratory system.
- Device Description: The device measures "expired Peak Expiratory Flow (PEF), Forced Expiratory Volume in one second (FEV1), Forced Expiratory Volume in six second (FEV6) and their ratio (FEV1/FEV6)." These are measurements of lung function, not analyses of samples taken from the body.
- Lack of IVD Characteristics: The description does not mention any analysis of biological samples (like blood, urine, tissue, etc.) or the use of reagents. IVD devices are specifically designed to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes.
The TD-7301 Spirometer is a medical device that measures physiological parameters related to respiratory function. It falls under the category of devices used for monitoring and assessment of a patient's physical state, rather than analyzing samples in vitro.

Dear Pei-Fen Yang:
We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

5) Indications for use
TD-7301 Spirometer is intended to monitor Peak Expiratory Flow (PEF), Forced Expiratory Volume (FEV) in home and professional healthcare environments.
The device is designed for use with children over 5 years old, adolescent and adult subjects.
6) Device Description
The TD-7301 Spirometer is a portable and handheld electronic spirometer used to measure expired Peak Expiratory Flow (PEF), Forced Expiratory Volume in one second (FEV1), Forced Expiratory Volume in six second (FEV6) and their ratio (FEV1/FEV6).
The users can transfer their measurement results from the TD-7301 Spirometer to iFORA smart on their mobile devices via Bluetooth. The iFORA smart provide an overview of users record with historical data and trend graph.
The TD-7301 Spirometer hardware is identical to the TD-7301 Peak Flow Meter cleared under K222810 (reference device).
7) Principle of Operation
The TD-7301 Spirometer is equipped with a removable mouthpiece and turbine connected to the peak flow meter. As patient puts the mouthpiece in the mouth and vigorously blows the gas through it, the turbine flow meter utilizes a unidirectional rotating vane with flow sensor to estimate the flow volume of gas at the present time and the maximum value of the whole process which is the Peak Expiration Flow rate (PEF). At the same time, the central processor measures the time of the entire process and calculates the flow volume integration on time. Taking the volume in the first second is the forced expiratory volume of 1 second (FEV1). The results will then display on the LCD screen of the device. For each of these two parameters, the result is a number shown on the screen of the TD-7301 Spirometer or on the smartphone screen. PEF and FEV1 are also associated with a four-zone monitoring system that, according to the result, may be green, yellow, orange, or red. Combined with forced expiratory volume of 6 second (FEV6) values, five stages of COPD classification are indicated on the right sidebar of the spirometer, from normal to stage IV, with stage IV being the most severe.
