Comparison of Negative Pressure Wound Therapies

Comparison of Negative Pressure Wound Therapies

The in-hospital use NPWT device is the mainstream for negative pressure wound therapy and can be used in continuous, intermittent mode with various pressure levels. Patients can rent or purchase the traditional powered NPWT device from hospitals and need to stay in the hospital during treatment.


Presence of Single-use NPWT Device

The single-use NPWT device makes a huge inroad on NPWT. With mobility inherent in design, patients can conduct NPWT at home. New upgraded version without power supply and canisters can further yield following benefits, including 


Advantages of New Single-use NPWT Device

1. Battery-free: The new device can create negative pressure environment over wound sites by suction. The new device can create negative pressure environment on the wound by manual compression without battery. It also provides less noise and vibration level to patients while using the device.

2.Canister-free: The multi-layered dressings are capable of absorbing exudate without additional canisters, making possible of a lightweight NPWT device.

3. Simplicity in operation and dressing change: With easy steps for setting and operation, patients can use NPWT devices intuitively. The visual, audible and tactile alarms enable patients to monitor the negative pressure level over wounds and remind of dressing change. Also, the dressings have good absorption and can be directly used on wound beds without further trimming, decreasing the discomfort caused by dressing changes.


For those patients with mobility, new NPWT devices unlash limitation of this treatment in time and space. What is more, it allows light showering and everyday activities for better life qualities.
