The negative pressure drainage material of electric field.
Background technology
Skin is the maximum organ of human body, mainly carries protection body, perspires, feels the functions such as cold and hot and pressure.Skin
Skin covers whole body, and it is exactly skin soft tissue multiple injury and combined injury that this, which is also resulted in most common in wound, damaged area, damage
Depth and wound reason difference can all cause the different situations of skin wound.If without rational treatment in time, easily occur
The problems such as severe infections, blood supply obstacle, refractory scar, have a strong impact on outward appearance and functional rehabilitation.
Negative pressure drainage technology is widely used in skin wound both at home and abroad and repairs field.Such as by negative pressure drainage technology
Tissue blood flow's Reperfu- sion of injury can substantially be increased applied to Acute fire；By negative pressure drainage technology be applied to dermatoplasty it
The surface of a wound afterwards, skin regeneration and quickening epithelium can be promoted to be formed；Negative pressure drainage technology is substituted applied to some skin coriums
On the biomaterial of thing, it can substantially accelerate revascularization；
Exogenous DC electric field is creeped, created many key links of the tissue repairs such as all nerve growths to surface of a wound epidermal cell
With important facilitation.However, due to applying exogenous DC electric field for a long time in the surface of a wound, operating level to be present for example positive and negative
For the inconvenience of selection and the fixation etc. of pole material with difficult, the technology does not obtain effective clinical conversion always.
The content of the invention
In view of this, it is an object of the invention to provide a kind of negative pressure drainage material for applying DC electric field.
The purpose of the present invention is achieved through the following technical solutions：A kind of negative pressure drainage material for applying DC electric field
Material, including " sandwich " sample foam dressing, bio-compatible transparent pad pasting one, positive and negative electrode paster；
" sandwich " sample foam dressing：It can be applied directional directly for the surface of a wound under conditions of having external direct current power supply and negative pressure
Flow electric field and drainage function is provided, including be positioned over the negative pole foam dressing of the conductive energy in surface of a wound center, around negative pole carbon
Fibrous foam dressing surrounding, the insulating foams dressing for being positioned over remaining position of the surface of a wound and around insulating foams dressing surrounding, place
In the positive pole foam dressing of surface of a wound surrounding normal skin, three forms horizontal " sandwich " spline structure；
Bio-compatible transparent pad pasting one：By pasting dressing and creating all normal skins, closed environment is provided for the surface of a wound, from
And it is carried out negative pressure drainage technology；
Positive and negative electrode paster：For connecting external power supply for both positive and negative polarity dressing, positive pole paster connection positive pole foam dressing, bear
Pole paster connection negative pole foam dressing.
Further, positive pole foam dressing and negative pole foam dressing are carbon fiber foam dressing, and insulating foams dressing is poly- Asia
Amine ester foam dressing.
Further, the bio-compatible transparent pad pasting one is the biological polyurethane pellicle with stickiness.
Further, the positive and negative electrode paster：Including bio-compatible transparent pad pasting two, Electricity conductive plaster and plug.Conductive label
Piece is located at the center of bio-compatible transparent pad pasting two, is connected by wire with plug.
The advantage of the invention is that：
1. pass through special design so that one piece of drainage material can be not only used for Wound-surface negative pressure drainage, while both positive and negative polarity dressing
Under conditions of having external direct current power supply, and can provides lasting or pulse orientation DC electric field for the surface of a wound.In other words, one piece
Material possesses two kinds of functions.
2. utilizing the material, organic collaboration of negative pressure drainage and electric field promotion organization repair can be achieved, i.e.,：By negative
Press drainage to reduce infection, promote granulation growth, good healing environment is provided for the surface of a wound；Promote wound by orienting DC electric field
Migration and nerve growth of all epidermises in the surface of a wound, so as to lift the efficiency of tissue repair and quality.
Brief description of the drawings
In order that the object, technical solutions and advantages of the present invention are clearer, the present invention is made below in conjunction with accompanying drawing into
The detailed description of one step, wherein：
Fig. 1 is the negative pressure drainage material structure figure that can apply DC electric field；
Fig. 2 is " sandwich " sample foam dressing structure chart；
Fig. 3 is positive and negative electrode paster structure figure；
Fig. 4 is the structure chart of bio-compatible transparent pad pasting one.
Embodiment
Below with reference to accompanying drawing, the preferred embodiments of the present invention are described in detail；It should be appreciated that preferred embodiment
Only for the explanation present invention, the protection domain being not intended to be limiting of the invention.
As shown in figure 1, the negative pressure drainage material that can apply DC electric field is made up of 3 parts, respectively by following 3 figures point
The structure of various pieces is not introduced.2 be " sandwich " sample foam dressing in figure；3 be positive and negative electrode paster in figure.Fig. 4 is biofacies
The transparent pad pasting of capacitive.
As shown in Fig. 2 the negative pole carbon that " sandwich " sample foam dressing includes being positioned over the conductive energy in surface of a wound center is fine
Dimension foam dressing 4, apply around negative pole carbon fiber foam dressing surrounding, the polyurethane insulating foams for being positioned over remaining position of the surface of a wound
Material 5 and around polyurethane insulating foams dressing surrounding, be positioned over the positive pole carbon fiber foam dressing of surface of a wound surrounding normal skin
3.To meet the needs of different shapes and sizes surface of a wound, three kinds of components of " sandwich " sample foam dressing can be cut into conjunction respectively
Conformal shape, so as to be advantageous to the synchronous progress that closed negative pressure drainage and exogenous electric field apply.
