Introduction

Clinical Mechanism of Negative Pressure Wound Therapy

1.All-Directional Active Drainage

All-directional active drainage leads to the removal of bacteria culture media and toxic decomposition of wound injured tissue, reducing the organism tissue’s reabsorption of toxic decomposition. It can help avoid uncontrolled systemic inflammatory response syndrome (SIRS), block the pathological reaction chain and prevent the happen of multiple organ dysfunction syndrome (MODS).

2.Safe and Effective Closure of Wound Surface

The semipermeable membrane constructs a sealed environment, preventing the bacteria from entering into the wound surface, meanwhile ensuring the moisture vapor transmission from the skin to the outside, leading the wound to closure.

3.Promote Wound Healing

The controlled all-directional negative pressure provides power for active drainage, helping accelerate topical blood circulation and promote granulation tissue formation.

Indication

Trauma & Orthopedics

Open fractures.

All kinds of defect and damages of skin or soft tissues. 

Avulsed wound or egloving injury.

Osteofascial compartment syndrome. 

Chronic osteomyelitis and wound caused by amputation.

Burn Surgery

Burn & scald, hot crush injury and high-explosive injury etc. 

Extensive burns. 

Deep second degree burn after eschar shaving and third degree burn after eschar excision (after shock period with vital signs stable) 

Wound surface before transfer of grafts

General Surgery & Cardiothoracic Surgery

Postoperation of mastocarcinoma radical operation. 

Postoperation of rectal carcinoma radital resection. 

Unhealing incision or stoma. 

Chronic empyema, bronchopleural fistula and fistula of esophageal anastomosis etc.

Hand and Foot & Microsurgery

Wound surface preparation before transfer of flaps.

 Grafts.

 Crush syndrome.

 Chronic wounds, including diabetic foot ulcers.

Contraindications

Patients with coagulation disorders or active bleeding.

Cancarous ulcer wound.

Complication

The most common complications of Negative Pressure Wound Therapy are maceration of skin and eczema etc.

There would be overgrowth of granulation tissue if the foam is covered over the wound for too long, which may cause bleeding of wound and damage to the tissue in removal of foam.

It may cause infection if there were residual foam left in the wound tissue.

Bleeding or even skin necrosis for lack of blood would happen if the setting of negative pressure were not appropriate.

Benefits

BIOCOMPATIBLE RETICULATED FOAM

1.Molecules in lower polarity, preventing the diffusion of bacteria with polarity. Inhibition of inflammation, improving the efficiency of wound healing.

2.Uniform pore size of foam. Complete contact with the wound surface for even pressure distribution.

3.Stronger van der Waals force between polymeric molecules, with thermosetting property, in stable structure which is not easy to be broken.

4.Easy to peel off and hard to be broken, with lower rate of residue.

BIOCOMPATIBLE POLYMER SEMIPERMEABLE MEMBRAN

The biocompatible polymer semipermeable membrane of Bodyguard is made by special process, in best proportion of polyurethane block copolymer, which ensures the best moisture vapor transmission rate. Meanwhile, it has the mechanic properties of tension, waterproofness, toughness and ageing resistance as excellent as polyurethane elastomer.

1.Better isolation from bacteria.

2.Hypoallergenic and non-irritant.

3.Higher moisture vapor transmission rate, more comfortable experience for patients.

UNIQUE ALL-IN-ONE SUCKER

1.Sucking disc with pre-applied drape, less application time and lower risks of leakage.

2.Softer material, improved experience and more comfort for patients.

3.Inner cavity for removal of exudate from wound surface. Outer cavities for monitoring negative pressure of wound surface.

4.Structure design based on fluid dynamics, reduction of block risk. Ensuring even distribution of negative pressure to every outer cavity, which can be monitored real-time.
