Description
Technical field
The present invention relates to medical intelligent instrument field, particularly a kind of closed negative pressure drainage device with feedback.
Background technology
Existing closed negative pressure drainage (VacuumAssistedClosure, VAC), also known as negative-pressure sealed drainage (NegativePressureWoundThreapy, or (VacuumSealingDrainageVSD) NPWT), utilize negative pressure suction device to be connected with special Wound dressing, subatmospheric pressure is produced off and on or constantly, by the Therapeutic Method of a series of mechanism of action wound healing at wound surface place.This technology is considered to the revolution in Wound treating field, can be applicable to various types of wound surface, comprises acute and chronic skin tissue defects wound surface, infective wound surface, skin grafted wounds and various Refractory Wound.
The core of VSD technology wraps up many side openings conductions pipe with foam material for medical use, the semi permeability sticking film that recycling has biological valve function is closed by drain district, make it to be hedged off from the outer world, become open wound into relatively closed wound surface, then connect high negative pressure source and form an efficient drainage system.Compared with traditional method, after using VSD technology, wound surface II processing time phase, total hospital stays of patient obviously shorten, and dressing change frequency, material consumption and antibiotic dosage and expense obviously reduce; Biological semi-permeable sticking film has good waterproof every bacterium property, effectively can avoid cross infection; Negative-pressure sealed drainage can keep not needing more change dressings in 7 ~ 10 days, dramatically reduces the workload of misery and the medical personnel frequently changing dressings and bring to patient.Although VSD technology achieves very large success at the various soft tissue defects for the treatment of with in infecting, also there is self limitation in it.First, VSD technology is a kind of simple wound surface drainage technology, and it promotes wound granulation tissue growth and accelerates the limited in one's ability of wound healing; Secondly, when using VSD technology, negative pressure makes foamed materials and wound surface tightly stick together, and inhibits the epidermis cell of edge of wound to creep to wound surface; Three, VSD will make wound exudate increase to the continuous negative pressure suction of wound surface, and containing a large amount of albumen in sepage, therefore easily there is negative nitrogen balance in body; 4th, negative-pressure sealed drainage makes wound surface be in drying regime all the time, is unfavorable for the healing of wound surface.
At present, in existing negative pressure treatment, its controling parameters generally only concentrates in the adjustment of whole system pressure, for the temperature of wound surface, the factor that sepage composition etc. can affect repair in trauma does not take into account, and administration is rinsed also many by Artificial Control, efficiency is low, not intelligent.
