Abstract
The invention discloses a vacuum liquid locking treatment system which comprises a compression type foam material layer, a viscose pasting film and a liquid locking material layer. The viscose pasting film is provided with pasting wings attached to the periphery of a wound surface. The liquid locking material layer comprises a compression water absorbing material layer and a one-way liquid permeable surface material layer. A liquid locking cavity is formed in a gap between the one-way liquid permeable surface material and the compression water absorbing material layer. One end face of the one-way liquid permeable surface material layer makes contact with the compression type foam material layer. After the viscose pasting film is attached to the portion surrounding the wound surface through the pasting wings, a first adsorption cavity is formed between the inner surfaces of the pasting wings and the outer surface of the wound surface, the volume of the first adsorption cavity is increased along with expansion of the compression type foam material layer after liquid absorption, sucked liquid is locked inside the liquid locking space through the one-way liquid permeable surface material and the compression water absorbing material layer, and even when the compression water absorbing material layer is extruded, liquid will not permeate back into a wound or a wound surface of a patient from the one-way liquid permeable surface material layer.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, particularly a kind of vacuum lock liquid treatment system.
Background technology
Due to present industrial expansion, the microgranule of in the air is more and more, keeps some small in the skin of human body surface
Dust and form dirt.Dirt positioned at skin surface can be cleaned out by having a bath, but the dirt positioned at deep skin
Do not cleared up by having a bath.Modern is by attempting containing chemical substance using clear imbibition and the patch of the cleaning with chemical substance etc.
Go to clear up the dirt of deep skin, although clean up the dirt of deep skin to a certain extent, but the chemical substance of residual
Skin can be impacted.
In terms of being also exactly wound care.Typically by adhesive bandage, Wound protection is got up.Adhesive bandage is generally medical
Polyurethane(PU)Adhesive bandage, the medical polyurethane(PU)Adhesive bandage is using the ventilative PU base material of import, and composite skins backing base material,
Make through cutting, sterilizing, packaging.Adhesive bandage is only used for the wound emergence therapeutic of fritter, so as to play temporary transient hemostasis, protection
The effect of wound surface.It should be noted that the time for using is unsuitable long.If using it too long, the adhesive plaster of adhesive bandage outer layer
Airtight.The skin whitening of wound and wound circumference will be made, the infection of the secondary for causing antibacterial that softens.Wound can thus be made
More deteriorate.Which is only capable of providing in the case that wound or wound surface do not occur sepage beneficial to the good of wound or wound healing
Good condition.However, for when wound or wound surface large area sepage, as adhesive bandage is unable to imbibition, its sepage remains in wound
Or wound surface surface, on the one hand it is unfavorable for wound or wound healing, on the other hand forms the focus of bacteria breed.In addition, existing
There is the wound-surface plaster of also some negative pressure-pumping drains, the sepage to wound surface is adsorbed and inhales the slough of wound depths
Go out, but these wound-surface plasters need external connecting negative pressure source, the sepage in wound surface could be adsorbed.Can be by skin now with one kind
Deep layer dirt adsorbs and/or adsorbs wound exudate and the compression negative-pressure vacuum system for suctioning out the slough of wound depths
System.But, although the lamellar compression-type sponge layer in the compression negative-pressure vacuum system can by liquid adsorption out, but piece
Shape compression-type sponge layer can not pin liquid, and when sepage reaches certain saturation degree, when firmly extruding, liquid can flow again
Road patient wound or wound, do not reach preferable effect.

The volume for stating the second adsorbent chamber 11 increases with expansion after 1 imbibition of compression-type sponge layer.
It is further used as preferred embodiment, after 1 imbibition of the compression-type sponge layer expansion, second absorption
Chamber 11 is connected with the first adsorbent chamber 10 by the 3rd adsorbent chamber.
Expand after 1 imbibition of compression-type sponge layer, viscose glue pad pasting 4 is gradually elevated, close except the first adsorbent chamber 10
Close space increasing, parital vacuum is formed, the sorption channel of 1 interior three-dimensional intercommunication of compression-type sponge layer is gradually recovered,
Parital vacuum is strengthened further, and as the confined space of the second adsorbent chamber 11 is increasing, parital vacuum is greatly strengthened,
1 parital vacuum of compression-type sponge layer is produced to wound surface and its deep soft tissue and is acted on long lasting for negative pressure-pumping, is reached
Wound, wound exudate suction, wound granulation soft tissue is gradually subsided a swelling and promotes the effect of local blood hemal ring.In the same manner, compression-type
1 parital vacuum of sponge layer produces negative pressure-pumping effect to the surface and its deep soft tissue that need dirt, gradually will be deep
Dirt in layer is discharged.
Be further used as preferred embodiment, the cross sectional shape of the adsorption hole is circle, rectangle, ellipse, trapezoidal,
One kind in semicircle, half elliptic or triangle.
It is further used as preferred embodiment, the thickness after 1 imbibition of compression-type sponge layer expansion is equal to 3 ~
Thickness before 20 times of 1 imbibition of compression-type sponge layer expansions.
It is further used as preferred embodiment, the first adsorbent chamber 10 after 1 imbibition of the compression-type sponge layer expansion
Volume be equal to the volume that 2 ~ 30 times of 1 imbibitions of compression-type sponge layer expand front first adsorbent chamber 10.
It is further used as preferred embodiment, the second adsorbent chamber 11 after 1 imbibition of the compression-type sponge layer expansion
Volume be equal to the volume that 2 ~ 30 times of 1 imbibitions of compression-type sponge layer expand front second adsorbent chamber 11.
It is further used as preferred embodiment, the compression-type sponge layer 1 is compression high-hydroscopicity polyvinyl alcohol
Material layer.
In addition, cannot seal wound surface or wound surface need not be sealed process in, the present invention is mainly using itself special construction
And there is the design feature for drying compression, large opening and imbibition ability with " pump effect ", and stronger suction force is produced, will
Sticky sepage is drained in material.Meanwhile, sepage or oozing of blood are real-time, flow rapidly into material, liquid flowing necessarily occur and are formed
Surface tension and its wound surface diverse location pressure difference, formed micro power.So, 24 hours continuous actions, micro power
Wound or wound surface blood circulation, detumescence can also be improved, promote the effect such as epithelial cell or granulation growth.
For mixed type, deep burn wound, the structure based on the present invention and rise parital vacuum suction function, wound surface
Sepage is integrally sucked dressing, can mitigate debridement intensity during clinician's operation;Reduce dressing change frequency.Because debridement intensity and
Dressing change frequency is reduced, and is damaged for " skin island cell " that mixed type, deep burn wound are gradually formed and is also reduced, is conducive to " skin
Island " generates and its " skin island " gradually merges flap coverage.Cicatrix residual after reducing clinical skin-grafting and recovering.
It is more than that the better embodiment to the present invention is illustrated, but the invention is not limited to the reality
Example is applied, those of ordinary skill in the art can also make a variety of equivalent modifications without prejudice to present invention spirit on the premise of or replace
Change, the modification of these equivalents or replacement are all contained in the application claim limited range.
