Abstract
The utility model discloses a novel composite negative pressure material which comprises a foam material layer and a wound surface contact layer, wherein the lower surface of the foam material layer or/and the upper surface of the foam material layer is/are provided with a wound contact surface with a three dimensional mutual communication space structure. Through the arrangement of the wound contact surface with the three dimensional mutual communication space structure below the foam material layer, the wound contact surface is soft, the wound contact surface keeps smooth with the foam material layer in the negative pressure drainage process, the wound contact surface does not stiffen after the negative pressure drainage process, and softly attached on the human body wound surface, so that the foam material layer does not directly contact the human body wound surface, direct stimulation of the stiffened foam material layer to the open wound or the wound surface of a patient is avoided; the wound surface bleeding and other problems due to the uncovering of the wound protection material when the wound protection material on the wound surface is replaced by the polyurethane foam material, so that the recovery of the open wound or the wound surface is benefited. The novel composite negative pressure material can be used as an enclosed wound surface negative pressure treatment device.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of NEW TYPE OF COMPOSITE negative pressure material.
Background technology
It is the critical material that on clinical medicine, various wound surface, particularly severe infections or larger area wound surface use negative pressure treatment technology that negative pressure is protected wound foam drainage material, and its performance directly determines clinical effectiveness and clinical indication scope.It is as follows that desirable negative pressure is protected wound foam performance: a) negative pressure is protected wound foamed materials and wound surface and placed for a long time adhesion, not hemorrhage while opening material, wound surface is not caused to secondary damage; B) negative pressure protect wound foamed materials can not additional antifungus agent and antibiotic, avoid the side effect such as topical antibiotic; C) negative pressure is protected after wound foamed materials dehydration exsiccation, should keep soft, avoids tissue and wound surface to oppress the side effect causing; D) to protect wound foamed materials elasticity suitable for negative pressure, can effectively conduct negative pressure, can avoid again elasticity to cause too greatly wound pain; E) to protect wound foamed materials absorbent good for negative pressure; F) negative pressure is protected wound foamed materials splendid negative pressure conductive performance, mesh intercommunication and mesh size to fit.
The conventional negative pressure of current clinical ability is protected wound foamed materials and is generally the aquation polyvinyl alcohol foam material (PVA) of one deck or Plant fiber's foamed materials of one deck polyurethane foamed material (PU) or one deck (being generally through chemical industry processing through chalina).
The performance deficiency of aquation polyvinyl alcohol foam material (PVA): a) the additional antifungus agent of foamed materials and antibiotic, prevent that aquation polyvinyl alcohol foam material (PVA) is mouldy, for example, but the side effect such as topical antibiotic are large: skin blister, violate medical routine and medical instrument management regulation; B) hardening (hardness and Gypsum Fibrosum are suitable) after material dehydration exsiccation, stimulates Principle of Pain discomfort, even causes negative pressure conduction failure, other side effect of patient failure and human body.
The defect of polyurethane foamed material (PU) and Plant fiber's foamed materials: a) material and wound surface longer-term are placed and wound surface adhesion, hemorrhage while opening material, cause wound surface secondary damage; B) because of vacuum suction effect, wound surface granulation is grown in polyurethane foamed material, and foamed materials embeds wound surface granulation, has the problem of changing foamed materials difficulty, even has after foamed fibre ruptures and remains in the risk in human body; C) material absorbent is not good.
In order to evade the risk of clinical Wound-surface negative pressure treatment technology, further improve the clinical result of use of Wound-surface negative pressure treatment technology, how improving the negative pressure contacting with human body, to protect traumatic material most important.
Utility model content
The purpose of this utility model, is to provide a kind of NEW TYPE OF COMPOSITE negative pressure material.
The solution that this utility model solves its technical problem is: a kind of NEW TYPE OF COMPOSITE negative pressure material, and it comprises sponge layer and wound surface contact layer, the lower surface of described sponge layer is or/and upper surface setting has the wound surface contact surface of three-dimensional intercommunication space structure.
As the further improvement of technique scheme, the laminated wound surface contact surface that arranges of described foamed materials, another side is provided with the adhesive film with sealing function.
As the further improvement of technique scheme, described sponge layer is polyvinyl alcohol foam material.
As the further improvement of technique scheme, described sponge layer is polyurethane foamed material.
As the further improvement of technique scheme, described wound surface contact surface is atactic copolymerized polypropene material.
As the further improvement of technique scheme, in described sponge layer, negative-pressure drainage tube is installed, described negative-pressure drainage tube is connected with negative pressure source.
The beneficial effects of the utility model: this utility model by arranging the wound surface contact surface with three-D space structure below sponge layer, wound surface contact surface is soft, and it is unobstructed between sponge layer that wound surface contact surface keeps in the time of negative pressure drainage, not hardening of wound surface contact surface after negative pressure drainage, also flexibly be fitted on human body wound surface, like this, sponge layer does not directly contact human body wound surface, open wound or the wound surface of avoiding the sponge layer after hardening directly to stimulate patient; Also avoid polyurethane foamed material in the time that traumatic material is protected in wound surface replacing, opened and protect the problems such as traumatic material initiation wound surface is hemorrhage, be conducive to the healing of open wound or wound surface.This utility model can be used as wound closure negative pressure therapeutic devices and uses.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in this utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described.Obviously, described accompanying drawing is a part of embodiment of the present utility model, rather than whole embodiment, and those skilled in the art is not paying under the prerequisite of creative work, can also obtain other designs and accompanying drawing according to these accompanying drawings.
