Indications for Use
The RTX3320 device is for use by patients at home. It is intended to be used in combination with a variety of patient monitors upon the prescription of a licensed physician or other authorized healthcare provider. RTX3320 serves as the remote communication link between compatible patient monitors, and the compatible healthcare facility at another location. The healthcare facility could be at a disease management center, or with the healthcare/wellness provider or other out-of-hospital caregivers. The purpose is to transmit selected medical information (such as weight, blood pressure, blood glucose) over a normal residential telephone line. RTX3320 is a "black box" device – it is not connected to the patient and not operated by the patient. The installation must be performed by or under supervision of an authorized professional healthcare company. This device does not measure, interpret or make any decisions on the vital data that it conveys.
Device Story
RTX3320 Wireless Telehealth Gateway acts as a 'black box' communication hub; receives physiological data (weight, BP, glucose, ECG) from compatible wireless patient monitors via Bluetooth; transmits data over public switched telephone network to remote healthcare servers. Installed by authorized professionals; not operated by patients. Device performs no measurement, interpretation, or clinical decision-making. Healthcare providers receive transmitted data at remote facilities to support clinical management. Benefits include remote monitoring of chronic conditions without requiring patient interaction with the gateway.
Clinical Evidence
Bench testing only. No clinical investigation performed. Verification and validation activities established performance and reliability. Compliance with IEC 60601-1, IEC 60601-1-2, FCC Part 15, and FCC Part 68 demonstrated.
Technological Characteristics
Hub/gateway device; Bluetooth wireless connectivity to patient monitors; PSTN modem for data transmission. Designed for home use. Standards: IEC 60601-1 (safety), IEC 60601-1-2 (EMC), FCC Part 15 (radio), FCC Part 68 (telecom). Risk management per ISO 14971:2000.
Indications for Use
Indicated for home-based patients requiring remote transmission of physiological data (e.g., weight, BP, glucose, ECG) from compatible monitors to healthcare facilities. Not for emergency calls, real-time alarms, time-critical data, or patients requiring direct medical supervision/emergency intervention.
Regulatory Classification
Identification
A radiofrequency physiological signal transmitter and receiver is a device used to condition a physiological signal so that it can be transmitted via radiofrequency from one location to another, e.g., a central monitoring station. The received signal is reconditioned by the device into its original format so that it can be displayed.

#### Discussion on differences:
ltem 1: The intended use / Indications for use for the predicate device and submission device is generally the same. The exact use is for both devices to be decided and supervised by a licensed physician or an authorized healthcare provider, but limited to be within the intended use and with respect to the contra indications and warnings which are also generally the same for both devices.
ltem 5 The predicate device is a system consisting of patient monitor devices, a hub/gateway device and a system server software. The Submission device is a hub/gateway device with a specified generic protocol interface to any compatible patient monitor, and with a specified generic protocol interface to any compatible system server. The protocols are validated against existing compatible patient monitors and servers, and in the labeling it is stated that only compatible and system validated patient monitors and servers must be used with the hub/gateway.
Verfication and validation done on the compatible patient monitors ensure that no extra safety or performance risks are added when using the submission device compared with the predicate device.
The server side and database management must always be validated by the responsible system operator or provider, and using the generic and properly documented protocol adds no extra safety or performance risks to a system using the submission device compared to the predicate device.

hecossary to portom the internable assess physiological parameters as the predicate device r to oubmibolon as now over otheraction on the device. If additional information is needed this may be achieved by a normal voice phone call.
may be arrithe predicate device the measurements taken are defined by the patient momitors that are a part of the system. For the submission device the measurements taken mention and by the specific compatible patient monitors. Because of the similar intended use and indication for use for both the predicate device and the submission device, the measurements will typically be the same.
Inoded.omomonik thir typecifications about the wireless link between the patient monitors and the Gateway for the predicate device are proprietary and not available for RTX Healthcare. Based on the knowledge available as a leading company within wireless connectivity RTX Healthcare has evaluated that many different short range radio solutions are suitable for this type of devices without adding any additional risks to the patient. RTX Healthcare has chosen the Bluetooth wireless technology used in other medical devices like the Nonin Pulseoximeter (FDA-K041156 ) developed by RTX Healthcare. The general radio signal safety requirements and FCC Part 15 rules are regulatory requirements that are equal for both the predicate device and the submission device. Since the only purpose using a wireless radio link is to replace a cable, the wireless link in the submission device is evaluated not to add any additional risks within the intended use compared to the predicate device.
Item 12: Detailed environmental specifications for the predicate device are proprietary and not available for RTX Healthcare. This is evaluated not to add any additional risks to the patient since both the predicate device and the submission device, according to the intended use, are designed for use by patients at home. The environmental specifications for the submission device are defined according to IEC60601-1 and specifications available for other medical devices for home use.
#### Performance data:
The RTX3200 device has been tested to meet the requirements of the following standards and regulations used as acceptance criteria:
IEC 60601-1, IEC 60601-1-2, FCC part 15 and FCC Part 68.
Risk management is performed according to ISO14971:2000.
Based on the fact that the performance comparison of the predicate device and the submission device show that the differences are minor and causes no harm to the user, and the fact that the intended use and indication for use is the same, it was early in the project decided to focus on verification and internal validation instead of large scale validation in form of clinical investigation.
Verification and validation testing activities is conducted to establish performance and reliability characteristics of the device.
