Description

A kind of instrument that promotes wound healing
This utility model relates to a kind of medical surgical treatment instrument, especially a kind of instrument that can promote the traumatic surface healing.
The wound healing problem is a very important problem of surgery research.Some prolonged wound surface of not healing, often to doctors and patients bring the pain if.Be emphatically the problem that example is talked about some relevant wound healings below with the burn treating.The principle that burn wound handles is: reduce stimulation again to wound surface to ease the pain 1.; 2. wound surface is kept clean to reduce infection chance; 3. can promote wound healing.At present, clinical method commonly used is two kinds of occlusive dressing and exposure methods.Occlusive dressing can reduce stimulation to wound surface because of moistening environment in when wrapping, eases the pain, but but can bring great pain to patient when changing dressings.Occlusive dressing helps wound healing because of moistening environment, can make to be in parabiotic histiocyte resurrection, again because of moistening environment is beneficial to the bacterial growth breeding, easily causes traumatic infection simultaneously, and serious infection can jeopardize patient's life again.So many at present opinions more seriously are difficult for debridement wound surface and the burn wound of large tracts of land (surpassing 30%) and burn wound's row exposure method of dark II degree completely for polluting.Exposure method can make the dry incrustation of wound surface, is unfavorable for bacterial growth, can reduce the chance of infection relatively, but exsiccant crust face brings pain for again patient's human body, and is unfavorable for wound healing, especially can make to be in the reduction of parabiosis histiocyte vigor, even downright bad, cause depth of burn to be deepened.If wound surface generation severe infections, the frequent wrapping of clinical many employings changes dressings drain wound surface extract, but also can be insufficient to reducing the anti-infective effect because of drain, even the people's death of can causing a disease, fire victim's main causes of death are concurrent severe infections, account for more than 50% of general mortality rate of burn, so the key of treatment burn is prevention and alleviates infection.The situation of some contradictions appears in above-mentioned two kinds of methods through regular meeting aspect treatment, so the problem on opportunity of its pros and cons and selection is the problem of arguement of burn brainstrust and research always, still do not have final conclusion at present.
The purpose of this utility model provides a kind of device that can promote wound healing, can be by this device to wound surface repetitively administered (liquid or gas) and wash wound surface on purpose under the situation of not opening wrapping dressing, play the abundant drain of wound surface, keep the wound surface cleaning, infection effectively, reduce infection chance, reduce dressing change frequency, alleviate the patient suffering.
For reaching above-mentioned purpose, this utility model is wrapped up locking device, Wound-surface negative pressure drainage system and wound surface input equipment by wound surface and is constituted.Wound surface wrapping locking device can be a medical poisonless sponge dressing and covers the adhesive, flexible thin film outward, so that can paste with normal skin around the wound surface.Built-in two conduits of sponge dressing, one is connected with negative pressure drainage device, and another is connected with wound surface input equipment.The Wound-surface negative pressure drainage system can be medical electronic vacuum extractor, and wound surface input equipment can be medical peristaltic pump.Wound-surface negative pressure drainage system and wound surface input equipment all can be controlled under certain program software at regular time and quantity, have made things convenient for operation.
After adopting said structure, because can be by wound surface input equipment on purpose administration and flushing of wound surface, flushing liquor and wound secretion can be passed through the abundant drain of negative pressure suction device again simultaneously, can provide moistening environment to be beneficial to wound healing to wound surface, wound surface is kept clean, reduce infection chance, can reach the anti-infective effect effectively by the on purpose medication of antibacterial of wound surface input equipment at wound surface.Transfusion can replace repeatedly with drain, and needn't be often change dressings more, reduced dressing change frequency, reduced the misery of bringing to the patient because of the stimulation of changing dressings to wound surface, help the healing of wound surface.As patient be in shock stage then this method especially seem important.Occlusive dressing above-mentioned is easy to make traumatic infection to be because it can not carry out due to the drain fully wound surface.By the attraction of Wound-surface negative pressure drainage system, wound surface is shunk and the promotion healing.When being used for the wound surface skin-grafting,, all can improve skin graft survival rate greatly no matter draw in the net skin-grafting or microgranule skin-grafting.Wound surface for anaerobic infection can be by wound surface input equipment input hydrogen peroxide or oxygen and negative oxygen ion gas etc., to improve antibacterial effect.Comparatively thorny for serious anaerobic infection (as gas gangrene bacillus) treatment clinically, mortality rate is higher, then can improve cure rate greatly by this device.Aspect plastic surgery's transfer of skin flap art, by this device can to flap alternately the massage of malleation and negative pressure promotes the blood fortune of flap to improve survival rate, strengthen the flap Aspect Ratio, reduce flap thickness, the raising therapeutic effect.
