Technical field
The present invention relates to technical field of medical instruments; especially a kind of on plateau, desert, island or other special environment generation war, natural disaster or vehicle accident and cause occurring batch wounded a time, at the scene treatment and after pass through the Portable wound surface having closed negative pressure drainage and pre-washing function concurrently used in journey and protect and therapy system.
Background technology
Along with closed negative pressure drainage (Vacuumsealingdrainage, VSD) treatment technology is more and more by surgeon is understood, its clinical practice is just presenting day by day universal gesture.This technology traditional drainage has been made to a kind of Novel drainage Therapeutic Method of significant improvement, original in early 1990s by doctor Fleischmann of hospital of attached the traumatology department of German Ulm university, within 1994, introduced domestic by professor Qiu Huade.Compared with traditional drainage method, first VSD solves blocked drainage tube problem.At drainage tube external medical foam (polyvinyl alcohol) parcel, make foamed materials become drainage tube and by the intermediary between drain lacuna or wound surface, block derivated just cannot enter drainage tube, thus the blocked phenomenon of drainage tube can not occur.Secondly, for ensureing there are enough negative pressure by drain district, utilizing the semi permeability pad pasting closed drainage district with biological valve function, making it to be hedged off from the outer world, then connect high negative pressure source (suction pump or negative pressure bottle), just define an efficient drainage system.In this efficient drainage system, be eliminated at the right time by the exudate in drain district and slough, can be reached " null set is gathered " state in drain district, wound surface obtains clean environment very soon.
Current VSD is used widely at orthopaedic trauma, general surgery, thoracic surgery, Urology Surgery and Department of B urn etc., and its multinomial advantage is extensively approved: (1) make can by time, up hill and dale outside lead body by the sepage in drain district, pus and the slough that comes off in efficient, omnibearing drain; (2) anti-bacteria propagation, controls traumatic infection; (3) alleviate edema, reduce vascular permeability; (4) increase the confession of wound surface blood, improve microcirculation, promote granulation tissue growth; (5) frequently need not change dressings, decrease medical worker's work, eliminate the hardship of changing medicine for patient.Based on above reason, VSD technology is called as the revolution progress of trauma care.In military medicine or disaster medicine, VSD also has good application prospect, and the wound surface through VSD process has stronger anti-infection ability, and send the time limit obviously to extend after can making, dressing change frequency significantly reduces, and medical care labor intensity significantly reduces.U.S. army begins namely to use VSD technology and products thereof in a large number from the war in Iraq, achieves good military medicine benefit.
But, obvious deficiency is still there is in existing VSD technology when being applied to field treatment, the line clogging problem of such as VSD still occurs often, especially when wound infection is comparatively serious, when wound exudate compares thickness, maybe when after long period drain, because drain reduces, pipeline environment is dry, and drain is especially easily dry incrustation also, thus blocking pipe.Clinician, in long-term practice process, has found out the way at drainage tube offside infusion normal saline gradually, solves this problem well certainly.Also find simultaneously, suitable infusion normal saline to prevention infection and wound healing very useful.Antibiotics or other medicine can also be added in normal saline, equal the perfect adaptation achieving naturopathy and Drug therapy, curative effect more better than simple VSD technology can be received.But in the wild under simple and crude condition, additionally set up reservoir channel and hang the complexity that normal saline bottle can increase VSD technology undoubtedly, increase casualty evacuation difficulty and nursing intensity, its practicality of remarkable reduction, if and do not take this measure, then be difficult to solve the susceptible to plugging problem of drainage tube, also do not reach desirable therapeutic effect.
