Abstract
An antibacterial, staltic and antalgic medical dressing for the wound on human body is prepared from polypropene, polyethene, spinning fused material, local anesthetic and chitin fiber cloth through loading the chips of polypropene or polyethene in a feeding hopper, heating, extruding out, filtering, pumping it to a fused material sprayer module, blowing the hot air into said sprayer module, to draw the molten material into fine stream, cooling, sticking it on the chitin fiber cloth while spraying local anesthetic, rolling by a pair of rollers, and winding.
Description
Technical field
The present invention relates to a kind of manufacturing and application that melts and sprays medical dressing cloth, particularly relate to a kind of antibacterial anti hemorrhagic analgesic medical dressing cloth and preparation and application.
Background technology
In the majority with the antibacterial anti hemorrhagic function in the existing medical dressing, general material has collagen protein, alginate fibre base cloth, chitin substrate material; The polymeric membrane synthetic material; Its defective is that the local organization of human body wound is not had local anaesthesia analgesia function, can't reduce the temporary transient pain of human body.The inventor applies for patent of invention (application number: be a kind of the local anaesthesia medicament to be dissolved in the polypropylene melt spraying super-fine-fiber self-adhesion cloth 200410052779.8), infiltrate the shallow epidermal tissue of human body by the slow release topical agent, thereby play analgesic activity, its defective is that this invention does not possess subjective antisepsis and hemostatic function.
Summary of the invention
The technical problem of solution required for the present invention provides a kind of multi-functional antibacterial anti hemorrhagic analgesia and melts and sprays medical dressing cloth and preparation method thereof, this medical dressing cloth has antibacterial anti hemorrhagic analgesia function, can be widely used in the dressing of human external wound mouth, army personnel's first-aid kit.
A kind of antibacterial anti hemorrhagic antalgic dressing of medical of the present invention comprises:
Polypropylene, polyethylene, the spinning melt of modification, local anesthesia medicament and chitin fiber cloth with active component are combined into one.
Described local anesthesia medicament and fusion spray cloth polymer chips weight ratio are 6～25%, and the grammes per square metre of chitin fiber cloth is 3～60g/m
2
Described local anesthesia medicament is tetracaine, bupivacaine, procaine or lignocaine.
The preparation method of a kind of antibacterial anti hemorrhagic antalgic dressing of medical of the present invention comprises the following steps:
(1) melt thread air-flow jeting process section
Deposit the section of the polypropylene of high fusion index or polyethylene in the hopper 1, squeeze amount after filter 3 through screw rod 2 fusions of heating, by dosing pump 4 quantitatively with melt Conveying to melting and spraying assembly 5,7, hot blast resistance furnace 8 is blown into the high speed hot blast and melts and sprays assembly stretching melt thread.
(4) the melt thread is drawn into bonding local anaesthetics powder of cloth and chitin fiber cloth operation section
The chitin fiber cloth that melt thread 17,18 is carried by 10 pre-volume buckets through high speed hot blast stretching postcooling physical adhesion also evenly are spilled into the local anesthesia medicine powder by 19, and three lamination are one.
(5) hot-rolling is pressed and is sticked into cloth operation section
By fusion spray cloth and the chitin fiber cloth that the melt thread forms, local anesthesia medicine powder trilaminate material grinds synthetic by a pair of pressure roller 14 and has the multi-functional medical dressing cloth in antibacterial anti hemorrhagic analgesic, and coils into tubular by 15.
Its melt index of pp material that described melt thread is a high fusion index: 18～500; Its melt index of high fusion index polyethylene raw material: 16～200.
The temperature in each district of the fusion of described fusion spray cloth is 60～315 ℃, hot blast temperature: 275～325 ℃, and blast: 1.2～8.5kg/cm
2, fusion spray cloth coiling speed: 5～60m/min.
The application of a kind of antibacterial anti hemorrhagic antalgic dressing of medical of the present invention through cutting into different shape and binder combination, can be applicable to the dressing of human external wound mouth, army personnel's first-aid kit.
Beneficial effect of the present invention:
1. adopt nontoxic polypropylene or the poly melt thread hot blast of health to melt and spray bonding chitin fiber cloth and local anesthesia medicament.Press stone roller to be integral because trilaminate material is a physics, do not influence the variation of original property of medicine and the decomposition of medicament.
2. have melt-blown micro fibre that leading wet effect and twine and cling chitin fiber cloth and local anaesthetics powder, slow release is to human body skin wound mouth then, thereby plays the multi-functional treatment effect of human antimicrobial hemostatic analgesia.
