Negative Wound Pressure Therapy Manufacturing Challenge



As a manufacturer who specializes in the production of multi-layered negative wound pressure therapy component parts for advanced wound care devices, we felt it important to support and help raise awareness of Diabetes during Diabetes Awareness Week. This condition can often lead to painful side effects such as Diabetic Foot Ulcers. Evidence suggests patients suffering from this can benefit from procedures such as Negative Wound Pressure Treatment to speed the healing process up as well as aid with reduction in incidence of infection with patients’ post-surgery (Guffanti 2014). 

the problem

Negative Wound Pressure Treatment (NWPT) devices require a variety of components including a complex adhesive dressing which is where our client approached us needing help. The client was unable to find a partner who could innovate a NWPT component manufacturing process that would cater to the complexities of this 350mm wide, 3-layer dressing. This dressing needed an application system, but also needed perforations which would allow for easy removal of the system once applied to the patient.

the solution

The PolarSeal team were able to design a customised manufacturing process including a variety of unique tools which would cater to the needs of this dressing. We were able to start with a hand assembly line and progress the development of this machine, to create a full-scale manufacturing line which could handle increased volumes over time.

the Result

Our team were able to engineer a bespoke machine within their cleanroom accredited facilities which could apply a handlebar application system to the dressing. The dressing could peel back liner 1 to expose the adhesive, apply to the patient holding the handlebars, remove the bars on application and then peel back the protective top liner to allow the dressing to then become breathable.
