NPWT – An Advanced Wound Care Treatment

Blog-Worth Considering Business NPWT

A wound care market analysis report from the US mentions that the global wound care market size was valued at USD 20.6 billion in 2021, it’s expected to grow at a compound annual growth rate (CAGR) of 4.1% from 2022 to 2030. Increasing surgical cases and the rising prevalence of chronic diseases globally is increasing the demand for wound care and wound healing products.

In addition, because of the influence of living habits, sedentary is one of the daily routines of many people, and this lifestyle is also leading to an increase in the prevalence of diabetes. This is one of the major factors contributing to the growth of the market. For example, in 2018, an estimated 34.2 million people, or 10.5 percent of the U.S. population, had diabetes, according to the American Diabetes Association. Additionally, nearly 1.6 million U.S. residents have type 1 diabetes, including approximately 187,000 teens and children.

And when diabetes is not well treated and controlled, it will increase the risk of diabetic complications. Among them, diabetic foot (DF) is one of the most common complications of diabetes. According to ScienceDirect, diabetic foot ulcers (DFU) can affect more than 25 percent of people with diabetes and can lead to amputation in 20 percent of patients. Patients must take the health of their feet seriously.

DF is difficult to heal, and there are many reasons for this.

  1. Patients with diabetes have reduced immunity, and their antibacterial and bactericidal abilities are weakened, so wounds are prone to infection.
  2. The affected area of these patients is generally accompanied by vascular disease, which will lead to weak local blood circulation, lead local tissue ischemia, and hypoxia, and ultimately affect the regeneration speed of the wound.
  3. Neuropathy, which also slows wound healing.

In the related treatment of DU, in addition to drug therapy and surgical treatment, more and more doctors choose NPWT to assist in the treatment of DU.


Negative Pressure Wound Therapy (NPWT) is now one of the advanced therapies in wound care. To put it simply, it is to use the drape to build a negative pressure environment on the wound surface, connect the negative pressure source through the drainage tube, form a closed vacuum environment, and continuously stimulate the wound surface and absorb exudates to keep the wound surface moist and inhibit the growth of bacteria. Promote the formation of granulation, and ultimately achieve the effect of accelerating wound healing.

How to operate NPWT

Compared with traditional wound care, NPWT can enhance blood circulation in the affected area, reduce the accumulation of exudate and the chance of wound infection, and shorten the time for wound healing. NPWT can also reduce the frequency of dressing changes, reduce pain and improve the patient experience.

What’s more, some studies have shown that compared with traditional wound care, NPWT can also save nurse time(3h). This may save hospital medical resources.


Since the invention of negative pressure therapy, more and more studies have proved its effectiveness in wound treatment, and more and more people have paid attention to this therapy. In 2021, the global negative pressure wound therapy market size is around USD 2.0 billion, and the forecast study predicts a compound annual growth rate (CAGR) of 6.7% from 2022 to 2030.

If you have an interest in the industry or want to add a new product line in 2023, negative pressure wound therapy might be worth considering.
