Sterilized Trauma Wound Dressing / Non Woven Adhesive Wound Dressing

Sterilized Non Woven Wound Dressing/Adhesive Non-Woven Wound Dressing for Single Use/Wound Dressing Set

Product Introduction

【Structure and composition】Type B products are composed of polyurethane PU sponge, negative pressure medical film, straight joint, Y-type joint and stop clamp and negative pressure drainage tube sleeve. The negative pressure drainage tube sleeve is composed of suction cup, suction tube, flushing tube, oxygen supply tube, oxygen cap and Luer joint parts, and the product is sterilized by gamma irradiation.

【Functional indications/indications】Disposable negative pressure drainage protection materials are used for negative pressure closure and drainage operations, drainage non-chronic wounds (such as surgical incisions, mechanical trauma, cut wounds, superficial second-degree burn wounds) and establish oxygen channels for aerobic wounds.

4.1 Medical foam
4.1.1 PVA foam: Honeycombed, with good three-dimensional structure and space, good permeability and water permeability, strong resilience and good biocompatibility. Physical properties: shrink and harden when the product is dry. Therefore, compared with PU foam, PVA foam is more suitable for wounds with more acute secretions with high negative pressure drainage.
4.1.2 PU foam: Composed of numerous filaments, the three-dimensional network is better in three-dimensional structure and space than PVA foam, and the density is only 1/3--1/5 of PVA foam. More breathable and permeable, excellent biocompatibility. Compared with PVA foam, PU foam is more suitable for the negative pressure sealing treatment of wounds with less dryness of various secretions and chronic refractory wounds.
4.2 porous suction tube
Silica gel material, cloth into the foam to enhance the drainage effect, strong compression resistance, according to the width and length of the foam to determine the number of porous suction tube and tube arrangement mode.
4.3 Porous flushing tube
Silica gel material, cloth into the foam to play the role of washing the wound surface, according to the width and length of the foam to determine the number and mode of porous suction tube.
4.4 Non-perforated connection tube
PVC or silica gel material, one end is connected with the flush tube installed in the foam through the corresponding specification of the joint, and the other end is connected with the guide tube through the corresponding specification of the joint.
4.5 Transparent breathable adhesive membrane
Pasting is an important material for wound closure, and the pasting process is also a key step. If wound closure and leakage directly affect the therapeutic effect of negative pressure sealing and drainage. According to different types and specifications of protecting and creating materials, different types and specifications of laminating membrane can be configured. See instructions for details.
 

Scope of application
In the mesenteric method, a single tube is generally pasted and sealed. When there are two or more tubes, it is more convenient and effective to use face-to-face pasting.
According to the wound area, size and shape, design the foam cutting, the drainage direction of the porous drainage tube or the suction cup joint, and the adhesive film sealing scheme.
As shown in the picture on the right: Cut the membrane to a width of 8--10cm, fold the centrifugal paper outward, then tear off the centrifugal paper, stick the folded edge of the folded membrane to the lower edge of the wound, place it on the wound foam, and paste the porous suction connection tube on folded film.
Apply an appropriately sized and collapsible membrane using a face-to-face paste and seal the entire wound.
8.6 Suction cup foam sealing method:
PU foam suction cup type and PVA foam suction cup type are different in structure and sealing method.
8.6.1 PU foam suction cup sealing method:
After the foam is cut, determine where the suction cup fittings will be placed on the foam and where the porous irrigation tube will enter the foam. Use a sterile scalpel to pierce the foam at an angle of 30-45 degrees, then touch the wound with sterile forceps, introduce the porous irrigation tube into the foam, and fix the porous irrigation tube in the foam by puncturing to play a certain role . Then, use two large suction cup membranes to seal the entire wound from the suction cup to the left or up.

Design foam cutting,
Determine where the suction cup fittings will be placed on the foam and where the porous contacts will be.
The perforated irrigation tube was inserted into the sponge wound at an angle of 30-45 degrees to the sponge suction surface for intermittent fixation. If the wound has sinus tracts and deep cavities, a sponge can be incised along the perforated irrigation tube for negative pressure therapy.

With the suction cup as the center, the entire wound surface is sealed with a special film made of PU sponge suction cup.

8.6.2 PVA foam suction cup sealing method: 
After cutting the foam, place it on the wound surface and seal it with PVA suction cup special membrane. First, let the flush tube interface on the suction cup go through the corresponding hole of the membrane, and then let the suction tube interface go through successively. Let the membrane stick close to the root of the flush tube and the suction tube, and then peel off the core paper from the upper and lower membrane of the suction cup and paste the fixed suction cup and foam respectively. 
Let the membrane stick close to the root of the flush tube and the suction tube, and then peel off the core paper from the upper and lower membrane of the suction cup and paste the fixed suction cup and foam respectively.

Tube connection:
 Y-joint, trapezoidal joint are used to connect various suction tubes in the medical foam according to functions.
