Adopt above -mentioned structure, owing to reduced the number of piles, reduced the filter screen promptly, reduced the technology step, reduced product cost to replace hydrophobicity mesh foam blanket for being provided with the rack -layer of propping up that is cellular through -hole, improved the efficiency that sees through of penetrant, correspondingly improved treatment.
Description
Technical field
This utility model relates to a kind of armarium, particularly a kind of negative pressure wound surface therapy equipment of accelerating wound.
Background technology
Negative pressure wound surface treatment technology (negativepressurewoundtherapy, NPWT) be the novel method of a kind of accelerating wound of rising in recent years, be widely used in the treatment of a series of Hard agglut wound, comprise acute, chronic, infected wound.This technology not only strengthens the drainage of wound surface, and can significantly accelerate to infect the closed of lacuna, promotes wound healing, significantly reduce antibiotic use, the generation of effectively protecting from infection, shorten patient's hospital stays, alleviate patient's misery, reduce medical personnel's workload.In negative pressure wound surface treatment technology, VSD drainage technology used comparatively general in recent years, VSD drainage technology, i.e. disposable vacuum closed drainage.The drainage method that tradition adopts, its drainage effect is unsatisfied with, and holds time short, easily causes blocked drainage tube and infect.And use VSD negative pressure drainage device, penetrating fluid is drawn onto in drainage bottle in time by high negative pressure immediately, can continue to drain up hill and dale the secretions of full wound surface and not easily block tube chamber, keep drain unobstructed, thus reduce secretions to the stimulation of wound surface, destroy the environment of bacterial growth, the blood circulation of local can be promoted again, stimulate healthy granulation tissue growth consumingly, be conducive to the immediate union of wound or provide good local condition for making skin graft.But due to needs use drainage bottle (being commonly called as hydrops tank), not only make VSD negative pressure drainage device structure relative complex, cause equipment cost higher, and cleaning work is wasted time and energy relatively.
Utility model content
The purpose of this utility model is to overcome above shortcomings in prior art, and provides a kind of reasonable in design, can not use that drainage bottle, manufacturing cost are lower, simple to operate, the good negative pressure wound surface therapy equipment of therapeutic effect.
The technical scheme in the invention for solving the above technical problem is:
A kind of negative pressure wound surface therapy equipment, it is characterized in that: comprise the negative pressure dressing for being fitted on wound, for generation of the negative pressure pump of negative pressure and the suction pipe for connecting negative pressure dressing and negative pressure pump, described negative pressure dressing comprises the apertured film layer for skin of fitting, for absorbing the hydroscopic high-molecular resin layer of penetrating fluid, for isolating the shelf layer of hydroscopic high-molecular resin layer and apertured film layer, the semi-transparent rete of aqueous vapor and the sucker pad for producing negative pressure on semi-permeable layer is appeared for the formation of enclosed space, apertured film layer, shelf layer, hydroscopic high-molecular resin layer, semi-permeable layer and sucker pad connect from bottom to up successively, apertured film layer is provided with the permeability hole of mesh, described shelf layer is provided with through hole straight-through up and down, one end of described sucker pad connected sucking pipe, the other end of suction pipe connects negative pressure pump.Apertured film layer is by arranging the permeability hole of mesh, ensure that penetrating fluid leads to hydroscopic high-molecular resin layer, penetrating fluid can be converted to solid particle state by hydroscopic high-molecular resin layer, when shelf layer can ensure to produce negative pressure, shelf layer can not be crushed, and simultaneously by through hole straight-through up and down, can ensure that penetrating fluid leads to hydroscopic high-molecular resin layer, semi-transparent rete possesses certain breathability, thus facilitates aqueous vapor to appear.Adopt said structure, owing to not needing drainage bottle, and adopt hydroscopic high-molecular resin layer absorb penetrating fluid and be changed to solid particle state, not only make overall structure simple, reduce product cost, and reduce the difficulty of cleaning work, make cleaning work health, convenience more; Be provided with the shelf layer of up and down straight-through through hole, improve penetrating fluid through efficiency, correspondingly improve therapeutic effect.Negative pressure pump of the present invention can adopt the micro air pump on market, and the compact (being similar to main flow handset size) of micro air pump, therefore this product negative pressure wound surface therapy equipment, has good portable characteristic, handled easily, use.
Further, as preferably, through hole is cellular setting.
Further, as preferably, described shelf layer adopts medical plastic material.
Further, as preferably, described sucker pad adopts silica gel material.
Further, as preferably, described negative pressure pump is used for the Miniature negative pressure pump providing 0mmHg-200mmHg negative pressure.
This utility model compared with prior art, have the following advantages and effect: owing to not needing drainage bottle, and adopt hydroscopic high-molecular resin layer absorb penetrating fluid and be changed to solid particle state, not only make overall structure simple, reduce product cost, and reduce the difficulty of cleaning work, make cleaning work health, convenience more; Be provided with the shelf layer of up and down straight-through through hole, improve penetrating fluid through efficiency, correspondingly improve therapeutic effect.
