Intended Use

This device is intended for use by medically trained personnel in a clinical setting to continually monitor and display diastolic, systolic, and mean blood pressures and pulse rate. The device is intended for use on adult patients with a palpable pulse.

Device Story

TL100 Tensymeter is a non-invasive blood pressure monitor; utilizes single-patient-use pressure sensor applied to wrist over radial artery; electronic interface module processes signals. Proprietary algorithms analyze radial artery pressure to derive diastolic, systolic, mean blood pressure, and pulse rate. Used by medically trained personnel in clinical settings. Output displayed as numerical values and pressure waveform; assists clinicians in continuous hemodynamic monitoring; enables real-time clinical decision-making for adult patients.

Clinical Evidence

Clinical testing performed to validate accuracy against AAMI Standard SP-10-1992. Results met or exceeded accuracy requirements for non-invasive blood pressure monitoring.

Technological Characteristics

Semiconductor pressure-sensing element; wrist-worn form factor; electronic interface module. Patient contact materials compliant with ISO 10993-1. Electrical safety per IEC 60601-1; electromagnetic compatibility per IEC 60601-1-2.

Indications for Use

Indicated for continuous monitoring of diastolic, systolic, mean blood pressure, and pulse rate in adult patients with a palpable pulse in a clinical setting.

Regulatory Classification

Identification

A noninvasive blood pressure measurement system is a device that provides a signal from which systolic, diastolic, mean, or any combination of the three pressures can be derived through the use of tranducers placed on the surface of the body.

## Device Description:

The TL100 Tensymeter is a non-invasive blood pressure monitor that utilizes a single patient use non-invasive pressure sensor placed on the wrist, over the radial artery, and an electronic interface module. The device uses proprietary algorithms to analyze the radial artery pressure and display diastolic, systolic, mean blood pressure, pulse rate and a pressure waveform.

## Intended Use:

This device is intended for use by medically trained personnel in a clinical setting to continuously monitor and display diastolic, systolic, and mean blood pressures. The device is intended for use on adult patients with a palpable pulse.

## Comparison of Technological Characteristics of New Device to Predicate Device(s):

The design of the TL100 Tensymeter utilizes a semiconductor pressure-sensing element applied to the wrist, over the radial artery, to obtain a pressure waveform in the same manner as the predicate device.
