Description

Sealing dressing used after negative pressure drainage tube is pulled out

Technical Field

The invention relates to the technical field of medical supplies, in particular to a sealing dressing used after a negative pressure drainage tube is pulled out.

Background

The negative pressure drainage technology is to utilize a thin plastic tube or a rubber sheet to stab the accumulated liquid or gas to be led out of the body beside a wound, and the opening of a drainage tube is connected to a drainage ball, a drainage bottle or a gastrointestinal pressure reducer to enable the wound to generate negative pressure, thereby achieving the purpose of negative pressure drainage. The drainage method has more advantages and stronger drainage effect; moreover, the wound is not required to be bandaged by pressurization, so that the patient feels comfortable; because the negative pressure is in the wound, the tissues are tightly attached, the wound is favorable for healing, and the secondary infection is not easy to occur. Mainly used for postoperative drainage of maxillofacial neck and chest major surgery.

The operation area is gradually recovered, after the drainage quantity is reduced to a certain degree, a wound is left in the operation area by pulling out the drainage tube or the rubber sheet, pathogens, air and the like can enter the operation area along the wound to influence the prognosis, and particularly for a patient with closed thoracic drainage, after the drainage tube is pulled out, the air enters the thoracic cavity, pneumothorax can be caused, and serious consequences can be caused; for a patient with a breast cancer postoperative dilator or a prosthesis implanted patient, after the drainage tube is pulled out, pathogens can enter an operation area along a wound, and the risk of postoperative infection is increased.

At present, after the tube is pulled out in the negative pressure drainage operation clinically, the wound is simply bound by gauze and vaseline gauze, so that pathogens and air cannot be effectively prevented from entering an operation area, and the dressing is not firm in pasting, easy to slip and complex to operate.

Aiming at the defects of the prior art, a research and development person needs to develop a sealing dressing used after the negative pressure drainage tube is pulled out, which can effectively prevent pathogens and air from entering an operation area, is firm in adhesion, not easy to slip and simple in operation.

Disclosure of Invention

In order to solve the problems in the prior art, the invention aims to provide the sealing dressing for the pulled-out negative pressure drainage tube, which can effectively prevent pathogens and air from entering an operation area, is firm in adhesion, is not easy to slip and is simple to operate.

In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a sealed dressing that is used for negative pressure drainage tube to extract back, includes A layer, B layer, C layer, D layer, its characterized in that: the A layer be hollow square frame isolation slip sheet, the B layer be the gauze layer that the frame scribbled the adhesive, the C layer is the sealing layer, the D layer is the gauze layer, above-mentioned A layer, B layer, C layer, D layer bond in proper order together, the skin layer is pressed close to on the A layer, the skin layer is kept away from on the D layer, the dressing is sealed in independent wrapping bag after the ethylene oxide disinfection.

Preferably, the layer A is square, the side length of an outer frame of the layer A is 10cm, and the side length of an inner frame of the layer A is 7 cm.

Preferably, the layer B is a square, the side length is 10cm, the center is a gauze layer of 7cm, 4 layers of gauze are arranged, and the frame coated with the adhesive is attached to the layer A.

Preferably, the layer C is square, the side length is 10cm, and the material is a transparent plastic film.

Preferably, the D layer is a square with the side length of 10cm, and the number of the D layers is 4.

The utility model discloses a beneficial effect that is used for sealed dressing after negative pressure drainage tube extracts:

1. the utility model has the advantages of common materials, simple manufacturing process and low price.

2. The utility model discloses convenient to use, the simple operation.

3. The sealing layer of the utility model can effectively prevent air and pathogen from entering the operation area.

4. The utility model discloses an aseptic technique can be guaranteed to aseptic packing.

5. The utility model is coated with adhesive, can be directly pasted with skin, and does not need to paste adhesive plaster.
