Abstract
The medical material is prepared with thermoplastic polymer EVA resin, modifier MBS, additive dibutyl phthalate, etc. in certain proportion, and through heating, kneading, plasticizing, rolling pressing and drilling. It has proper plasticizing temperature and high reliability, and may be used in settling fracture and artificial limb sleeve and in protection after surgical operation.
Description
The present invention relates to a kind of fixedly plasticity immobilization material of fracture site of fracture patient that is used for, relate in particular to a kind of medical adhesive high molecular material.
At present; overwhelming majority hospital all adopts traditional closed-plaster method when fracture patient is implemented interim external fixation and convalescence protection; though this method can play the fixedly effect of fracture site; but make troubles to patient because gypsum material is heavy; airtight because of Gypsum Fibrosum again, thus patient's illing skin redness caused.In order to solve the fixedly problem of materials of fracture patient fracture site, Japan, China, Britain have also successively developed various immobilization materials, but the materials hot deformation temperature that has is too low, easy deformation, and the expensive that has is not suitable for Chinese common people's consumption.
Purpose of the present invention be exactly provide in order to overcome the defective that above-mentioned prior art exists that a kind of material source is wide, cost is low, makings is simple, plastic temperature suits, service-strong medical adhesive high molecular material and manufacture method thereof.
Purpose of the present invention can realize by following scheme: a kind of medical adhesive high molecular material, it comprises thermoplastic polymer, modifier and additive, described thermoplastic polymer is EVA (ethene-vinyl acetate), and its content is 50～95% (weight); Described modifier is selected from any one or a few in MBS (MBS), chlorinated polyethylene, abietic resin, polyamide, nitrile rubber, acrylic resin, the medical pressure-sensitive adhesive raw material, and its content is 3～25% (weight); Described additive comprises plasticizer, lubricant, coloring agent, and its content is 2～20% (weight).
Described additive also comprises filler, and its content is 0-5% (weight).
Plasticizer in the described additive is selected from that dibutyl phthalate, phthalic acid are two sad, in di-n-butyl succinate, trioctyl phosphate, phosphoric acid-benzene dioctyl ester, dioctyl adipate and the epoxy soybean oil raw material any one or a few, lubricant is a paraffin, and coloring agent is inorganic or organic pigment.
Described filler is calcium carbonate, Pulvis Talci or mica powder.
A kind of manufacture method of medical adhesive high molecular material, it comprises following processing step:
(A). with each material in the described ratio of claim 1 mix homogeneously in the kneader of heating;
(B). above-mentioned material is plasticated in roller machine or banbury or extruder, and plasticization temperature is 100 ℃～180 ℃;
(C). plastifying material is rolled into the sheet material of 0.1mm～10mm on calender;
(D). above-mentioned sheet material is punched, and cut into required size and shape with shape cutting machine.
Compared with prior art, because the present invention has adopted above method, make the immobilization material that makes have the effect of low-temp reversible thermoplastic self-adhesion, this material is a rigid sheet when-10 ℃～45 ℃ temperature, bending strength 20Pa～70MPa, tensile strength is 20MPa～60MPa, if be heated 60 ℃～80 ℃, the material softening self-adhesion may be formed into required form.The immobilization material that the present invention relates to is used for substituting Gypsum Fibrosum to the fixing of fracture site and rehabilitation protection, has easy to use, ventilative, in light weight, patient and feels comfortable, doctor's simple operation and other advantages.
Below in conjunction with embodiment, the invention will be further described.
Embodiment 1
Get EVA70 kilogram, 10 kilograms of medical pressure-sensitive adhesive, 8 kilograms of MBS, 7 kilograms of abietic resins, 1 kilogram of coloring agent, 1 kilogram in paraffin, 3 kilograms of dioctyl phthalates, above material is heated back the plasticating of kneading in extruder in kneader extrude, plasticating temperature is 150 ℃, on calender, roll into the sheet material of 2～3mm then, and on sheet material, beat the aperture that diameter is 2～3mm with 3～5 every square centimeter density.The product that so obtains can be used for arm and fractured leg patient's arm and fixing of shank.Can soften when it is heated to 60 ℃～75 ℃, and overlap self-adhesion by head and the tail behind the parcel fixation, the cooling back is fixing, behind the patients ' recovery, immobilization material is heated to 50 ℃ can removes fixing.
Embodiment 2
Get EVA60 kilogram, 8 kilograms of acrylic resins, 7 kilograms of MBS, 5 kilograms of polyamides, organic white 1 kilogram, 2 kilograms in paraffin, 6 kilograms of dibutyl phthalates, 6 kilograms of dioctyl phthalates, 5 kilograms of calcium carbonate, above material is heated back the plasticating of kneading in extruder in kneader extrude, the intensity of plasticating is 180 ℃, on calender, roll into the sheet material of 5mm then, and on sheet material, stamp aperture equably.The product that obtains thus can be used for the shoulder of clavicle and cervical region fracture patient and fixing of cervical region.Described product both sides two overlap edges that can also stretch out, when fixation is big, can be by two overlap edges overlap joint self-adhesions.
Embodiment 3
Get EVA90 kilogram, 7 kilograms of MBS, inorganic yellow 0.5 kilogram, 1 kilogram in paraffin, 1.5 kilograms of trioctyl phosphates, above material is heated the kneading back in kneader plasticate in banbury, plasticating temperature is 100 ℃, on calender, roll into the sheet material of 0.5mm then, and on sheet material, stamp aperture equably.The product that obtains thus can be used for fracture of finger patient's finger section to be fixed.Fixing means is identical with embodiment 1.
In addition, immobilization material of the present invention also can be used for the extended immobilization of artificial limb cover, or is used for postoperative protection etc.
