Description
Technical field
The present invention relates to the visual negative-pressure sealed drainage of a kind of wound surface wound surface cladding system.
Background technology
The concept of Wound-surface negative pressure closed drain is equaled to propose in 1993 by the German ULM Fleischmann of university the earliest, by the lot of documents report, confirms that its clinical effectiveness is definite.At present, Wound-surface negative pressure closed drain has been applied to nearly all surgical fields such as general surgery, orthopaedics, department of plastic surgery, and the clinical practice indication enlarges gradually.
Mainly being formed by wound surface filling dressing, sealing semipermeable membrane, drain pipeline and depression generator etc. of Wound-surface negative pressure closed drainage device.Wound surface is filled to dressing, and according to wound surface, cutting is placed on the wound surface surface, with the translucent sealing of sealing, with the drain pipeline, wound surface being filled to dressing is connected with depression generator, open depression generator, wound surface is filled dressing and is subsided, without gas leakage sound, mean to form negative pressure, Wound-surface negative pressure closed drainage device is effective.It is mainly medical sponge that the wound surface of current clinical use is filled dressing, all opaque, can't observe at any time the wound surface situation in use procedure, without objective inactive index, find that wound surface still is not suitable for further surgical intervention after wound surface is filled dressing if open, need reuse Wound-surface negative pressure closed drainage device, not only can't determine best occasion for the treatment, also increase patient's financial burden.The wound surface of current clinical use is filled dressing and dressing surface and surrounding skin need be sealed with pad pasting, when near being applied to some, skin has sepage or the incomplete wound surface of epidermis, in often having to pad pasting, near skin is sealed in, be unfavorable for the recovery of sepage skin.
Summary of the invention
Technical problem to be solved by this invention is: for the wound surface used in prior art, fill the problem that dressing can not be observed the wound surface situation at any time.
In order to overcome, use existing wound surface to fill the deficiency that dressing can not be observed the wound surface situation at any time, this patent provides a kind of negative-pressure sealed drainage wound surface cladding system, apply this wound surface cladding system and can observe at any time wound surface, not only facilitate the clinician to formulate treatment plan, shorten treatment cycle, also reduce the probability of changing Wound-surface negative pressure closed drainage device, alleviated patient's financial burden.
The technical scheme that the present invention takes is:
The visual negative-pressure sealed drainage of a kind of wound surface wound surface cladding system, comprise housing, medical sponge, air bag and piston element; Described medical sponge directly sticks on wound surface, and housing directly covers on medical sponge and lower end and contacts with the normal skin around wound surface, and described air bag penetrates the housing top and is connected with housing;
