Description
Technical field
This utility model belongs to field of medical device, specifically, relates to a kind of wound closure applicator of built-in flushing drip tube.
Background technology
Negative pressure wound surface treatment (Negative Pressure Wound Therapy, NPWT) is a revolutionary progress for the treatment of complexity wound surface in the last few years.1992, German doctor of medicine Fleischmann initiated and is closed and the method for traditional negative pressure drainage in conjunction with wound healing by wound surface.This method is widely used in covering and the drain that tissue defect or internal organs caused by the various acute or chronic wounds of body surface and ulcer, large area soft tissue defects, War injury such as to expose at the wound surface in situation very soon; In addition, the method can also be applied to the treatment of various infectious soft tissue injury.
In the process of application NPWT technology, perforate dressing is of paramount importance part.Dressing filling is direct flap coverage tissue also, for keeping wound surface moistening, is the local environment that wound healing manufacture is suitable for.Under vacuum suction edema and exudate through dressing micropore by drain.The swabbing action that negative pressure produces changes the pressure of dressing to tissue surface into, part wound tissue can be made to be absorbed in dressing hole, thus make wound tissue produce micro-deformation and and interface between stress, tissue tension is caused to change, activating force pathway, thus promote propagation and the differentiation of cell, accelerate the formation of new granulation tissue.Therefore, dressing is the key factor affecting NPWT therapeutic effect.
Carry out in the process for the treatment of in use dressing at present, physicochemical property and the structure drawback of dressing materials self appear gradually.Dressing micropore easily blocks to have research worker to find, once blocking will cause negative pressure treatment to lose efficacy, and can add the infection of heavily contaminated wound surface.Other research worker carry out quantitative study discovery to the bacterial number of dressing: the antibacterial that can find more than a kind in the dressing of 97%, has two or more antibacterial in the dressing of 54%, when NPWT treats, in dressing, bacterial number maintains 10
4cFU/ml ~ 10
6the high level of CFU/ml, conventional more change dressings effectively can not reduce bacterial number.
In addition, the dressing of different pore size also can produce different problems: aperture dressing more easily blocks, and causes inadequate drainage; Macropore dressing then easily causes granulation tissue to grow in micropore, causes fresh hemorrhage, bring considerable distress to patient when more change dressings.
To sum up, existing wound closure applicator, cannot solve dressing blockage of the micro orifice and granulation tissue simultaneously and grow to problem in micropore; And cannot realize sending to dressing and wound surface, the poor effect of therefore lavation and flushing by comprehensive for medicinal liquid, the needs of clinical treatment cannot be reached.
