Abstract

The invention discloses a wound surface therapeutic apparatus according to the principle of the negative pressure and a biological electric field to promote the wound surface repair. The wound surface therapeutic apparatus comprises a supporting cover, a one-way vent valve, electrode plates, a telescopic electrode probe, a power positive and negative electrode contact handle and guide lines. A base of the supporting cover is flat and soft, the electrode plates are installed in the base of the supporting cover and embedded into the base of the supporting cover, the exposed surfaces of the electrode plates are used for making contact with a wound surface, the electrode plates are connected in series through one guide line, and the supporting cover can properly deform according to the contact radian of the wound surface. The electrode plates are connected with the power positive and negative electrode contact handle on the base of the supporting cover through the guide line; the telescopic electrode probe is installed on the side wall of the center of the supporting cover; the electrode probe is externally connected with the power positive and negative electrode contact handle on the outer side wall of the supporting cover through one guide line. The side wall of the supporting cover is provided with the one-way vent valve which is externally connected with a negative pressure generation device. According to the wound surface therapeutic apparatus, negative pressure is formed in the supporting cover through the negative pressure suction, the wound surface therapeutic apparatus is externally connected with a power source to form a biological electric field in the area of the supporting cover, and therefore the healing of the wound surface is promoted rapidly.

Description

Wound surface therapeutic apparatus

Technical field

The present invention relates to a kind of short wound surface quickly-healing therapeutic instrument, especially for the reparation of soft tissue injury.

Background technology

Soft tissue injury is on the impact of body except bringing the pain of damage location, and damage location skin injury often causes infection, and more severe patient can cause infection to diffuse to whole body.So wound closure is most important to the treatment of soft tissue injury in time.At present the therapeutic modality of soft tissue injury has negative pressure treatment technology and the theoretical research of the short wound healing of bio-electric field that gains public acceptance, the effect that both can play short histiocyte division, breed, move to Chuan Mian ∕ wound center oriented in treatment soft tissue injury process, and can stimulate vascular cell to move to Chuan Mian ∕ wound, make damaged tissue occur new vessels, thereby promote wound repair.

Summary of the invention

The object of this invention is to provide a kind of wound surface therapeutic apparatus, in order to reach the object of sealing as early as possible soft tissue wound surface, the present invention, in conjunction with negative pressure technique and bio-electric field technology, stimulates wound surface to accelerate healing.

In order to reach this object, the technical solution adopted in the present invention is:

A kind of wound surface therapeutic apparatus comprises support cover, one-way ventilating valve, electrode slice, retractable electrode probe, power positive cathode contact handle, wire, it is characterized in that: described one-way ventilating valve is located on support cover sidewall, can external connecting negative pressure generating means, electrode slice is connected by wire, be positioned at support cover base, and be connected with the power cathode contact handle on support cover base by wire, medial wall, support cover center is provided with a retractable electrode probe, and electrode catheter is connected in the positive source contact handle of support cover lateral wall by wire.

Described support cover is " fornix " shape structure that medical silica-gel is made, and certain deformation can occur, and outwards in outstanding central part, leaves space, and edge part is thin layer annular slice structure.

Described one-way ventilating valve is located at support cover sidewall, can external connecting negative pressure generating means, and one-way ventilating valve and support cover are structure as a whole, and its material is identical with support cover.

Described electrode slice is a plurality of, and by the wire conductive path that is in series, be arranged in support cover base, electrode slice bottom surface and support cover base edge are positioned in same level and are exposed to outside support cover, more than be partially submerged in support cover marginal texture, electrode slice is that nontoxic conductive material is made.

Described electrode catheter is arranged on medial wall, support cover center, and this probe is arbitrary shape, has retractility, and its material is that nontoxic conductive material is made.

Described power supply positive and negative electrode contact handle is arranged on respectively support cover top and base edge portion lateral wall, the former is connected with retractable electrode probe by wire, the latter is connected with electrode slice conductive path by wire, and contact handle material is made by nontoxic conductive material.

Described one-way ventilating valve is funnel-shaped structure, and central authorities are provided with round vent, is provided with one-way cock in passage, and it can outwards aspirate air, but can not inwardly inject air.

Because the present invention combines Wound-surface negative pressure treatment technology and bio-electric field treatment technology, by negative pressure and bio-electric field combined effect in wound surface, thereby promote wound surface quickly-healing.

Accompanying drawings:

Fig. 1 is wound surface therapeutic apparatus full figure.

Fig. 2 is wound surface therapeutic apparatus side cross-sectional views.

Fig. 3 is wound surface therapeutic apparatus ground plan.

Wound surface therapeutic apparatus support cover (1) sidewall is provided with one-way ventilating valve (2) as shown in Figure 1, in support cover (1) base, be provided with electrode slice (3), electrode slice (3) is by wire (7) series connection, series electrical pole piece (3) group is connected with power cathode contact handle (6) by wire (7), medial wall, support cover (1) center is provided with retractable electrode probe (4), and electrode catheter (4) end is connected with positive source contact handle (5).

During concrete enforcement, whole wound surface therapeutic apparatus support cover is put in to wound surface, electrode slice in support cover base contacted with wound week, regulate electrode catheter length, it is contacted with wound surface center, in power supply contact handle, connect the power supply that therapeutic domain voltage can be provided, make to form bio-electric field in this support cover and reach therapeutic purposes; In the one-way ventilating valve place of support cover sidewall external connecting negative pressure generating means, make to form negative pressure in support cover, reach negative pressure treatment object, thereby both apply promotion wound surface quickly-healing simultaneously.

The invention is not restricted to the scope of embodiment, every method that bio-electric field can be provided and carry out Wound treating in conjunction with negative pressure technique, all within protection domain of the present invention.
