The summary describes a standard negative pressure wound therapy system with electro-mechanical components and visual/acoustic indicators. There is no mention of AI, ML, or any data processing that would suggest the use of such technologies. The performance studies focus on basic device functionality and safety, not on algorithmic performance.
Yes
The device is indicated for promoting wound healing, which is a therapeutic benefit.
No
The device is a suction device (NPWT) that promotes wound healing by removing exudate and infectious materials. It does not perform any diagnostic functions like detecting, diagnosing, or identifying diseases or conditions.
No
The device description explicitly states it is an "electro-mechanical pump system connected through a flexible tube to a super-absorbent, gentle adhesive dressing," indicating it includes significant hardware components beyond just software.
Based on the provided information, the PICO 7 device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to promote wound healing via the removal of exudate and infectious materials using negative pressure. This is a therapeutic function, not a diagnostic one.
- Device Description: The device is described as a pump system connected to a dressing for applying negative pressure to a wound. This aligns with a therapeutic device, not a device used to examine specimens from the human body to provide diagnostic information.
- Lack of Diagnostic Function: There is no mention of the device analyzing biological samples (like blood, urine, tissue, etc.) to provide information about a patient's health status or disease.
- Performance Studies: The performance studies focus on the device's ability to maintain negative pressure, manage fluid, and the functionality of its indicators. These are performance metrics for a therapeutic device, not diagnostic accuracy metrics like sensitivity, specificity, or AUC.
In summary, the PICO 7 is a therapeutic device used for wound management, not a diagnostic device used for analyzing biological samples.

PICO 7 Single Use Negative Pressure Wound Therapy System is suitable for use in both a hospital and homecare setting.
Comparison between New and Primary Predicate Device
The Indications for Use statement of the PICO 7 Single Use Negative Pressure Wound Therapy System is identical to that of the primary and secondary predicate devices. The technological principal for delivering the negative pressure wound therapy for both the subject and predicate devices are identical. The main differences between the subject device and the primary predicate device are:
6
-
- Introduction of a check valve (1-way valve) into the PICO 7 device to isolate the internal air leak caused by the normal operation of the pump mechanism from the pressure sensor.
-
- To enable the addition of the check valve (1-way valve), the manifold within the device casing required resizing.
-
- Minor software amendments which have been submitted as part of this 510(k) application. The amendments do not affect the performance, function, or indicators of the device.
-
- Extension of shelf life of PICO 7 system from 6 to 18 months.
The following testing has been completed on the subject device:
Non-Clinical Tests (Bench)
Wound Model Testing
Wound model testing was conducted on PICO 7 Kits (10x20cm and 25x25cm dressings) at low and moderate flow rate in vertical and horizontal positions.
The results of the tests showed that all of the dressings managed fluid at a flow rate modelling a low (0.6 g/cm²/24 hours) and a moderately exuding wound (1.1 g/cm²/24 hours) respectively for a simulated wound of 25% of the dressing absorbent pad area. The results also showed that the dressings maintained negative pressure within the test requirements of -60 mmHg to -100 mmHg for a minimum of 95% of the test time at the simulated wound base throughout the test. Based on the results of the tests it can be concluded that the PICO 7 systems can be used for their intended purposes.
Visual Indicator Performance Testing
- . Dressing Full Indicator
Testing was conducted on the PICO 7 system using water and simulated wound fluid to simulate a worst case scenario where the dressing reaches
7
maximum capacity and the filter in the dressing becomes blocked with fluid.
All test results showed when the dressings reached their maximum capacity the subject device was able to detect blockages and activate the "dressing full" indicator no later than 2 hours after the occlusion had occurred.
Based on the test results, it can be concluded that the PICO 7 devices can be used for their intended purposes.
Air Leak Indicator .
Air leak testing was conducted on PICO 7 by introducing deliberate air leaks into the system to show that when the system has a high leak rate, the leak indicators activate to alert the user to inspect the dressing application and address the point of air ingress/ air leak.
Test results showed that air leak indicator was activated at specified time points in line with the test requirements representing the initial application of the system to achieve the therapeutic negative pressure range of -60mmHg to -100mmHg (target -80mmHg); and maintenance of the therapeutic pressure range.
Based on the test results, it can be concluded that the PICO 7 devices can be used for their intended purposes.
Low Battery Indicator .
Low battery indicator testing of the PICO 7 system at pre-defined time periods which allow users to respond to the battery state.
The device was operated until the "battery low" indicator was activated, once activated, the device was continued to be operated for a minimum of a further 12 hours to ensure that the device reached "critical battery low" state.
8
All test results showed that the "battery low" indicator activated and flashed for a minimum of 12 hours prior to the device entering "critical low battery" state and that once the device had entered the "critical low battery" state, pressing the play/pause button of the device enabled the "battery low" indicator to flash 3 times.
Based on the test results, it can be concluded that the PICO 7 devices can be used for their intended purposes.
Acoustic Testing
Acoustic testing was conducted to demonstrate that the level of noise emitted from the subject device whilst addressing the internal air leak caused by the normal operation of the pump mechanism remained acceptable as defined within ANSI/AAMI HE75:2009/(R)/2013 in line with the recommendation for frequent peaks at night in a convalescent area.
Test results showed that during the normal operation of the pump mechanism, the subject device emitted an average noise level of 27.6dB and that the maximum noise emitted by the device (LAFmax) did not exceed 35dB in accordance with ANSI/AAMI HE75:2009/(R)/2013.
Based on the test results, it can be concluded that the PICO 7 devices can be used for their intended purposes.
Electromagnetic Compatibility and Electrical Safety Testing
PICO 7 Single Use Negative Pressure Wound Therapy System has been tested and assessed respectively and has been found to be in compliance with the following standards:
- AAMI / ANSI ES60601-1:2005/(R)2012 And A1:2012 C1:2009/(R)2012 And A2:2010/(R)2012 (Consolidated Text) Medical Electrical Equipment -

Shelf Life
The PICO 7 system has been evaluated using real time and accelerating ageing challenge conditions and a combination of simulated wound model testing as well as specification testing to demonstrate system functionality over the duration of the shelf life.
Test results showed that all dressings managed fluid at a flow rate modelling a low (0.6 g/cm²/24 hours) and a moderately exuding wound (1.1 g/cm²/24 hours) respectively for a simulated wound of 25% of the dressing absorbent pad area. The results also showed that the dressings maintained negative pressure within the test requirements of -60 mmHg to -100 mmHg for a minimum of 95% of the test time at the simulated wound base throughout the test. Furthermore, all specification test results complied with the acceptance criteria as defined within the test requirements. The results of all tests showed that the subject device was able to maintain its functionality over the duration of the ageing study and that a
10
shelf life of 18 months can be applied to the PICO 7 system. Therefore, it can be concluded that the PICO 7 systems can be used for their intended purposes.
Conclusions
In establishing substantial equivalence to the predicate device, Smith & Nephew Medical Ltd evaluated the indications for use, materials, technology, product specifications and energy requirements of the device. Performance testing, service life testing and electrical safety testing has been completed to demonstrate that the PICO 7 Single Use Negative Pressure Wound Therapy System is substantially equivalent to the primary and secondary predicate devices for the intended use.
