1, detection compares glue-line degree of integration, peel strength and holds viscosity after dressing is made.2, simulation uses the damage to skin Evil.The degree of integration of the bearing hydrocolloid dressing of separation net 3 test product as a comparison is not added.
Experimentation:
Degree of integration test: taking size is the bearing hydrocolloid dressing of 5cm × 5cm, peels release paper 4 off, and it is raw to be soaked in 200ml It manages in salt water, shakes 24 hours, test its concussion front and back mass change.
Peel strength and viscosity is held referring to " the 4th part of YY/T1293.4-2016 contact Wound dressing: bearing hydrocolloid dressing " Test.
Simulation uses test: sample being pasted on the intact skin of normal personnel and is tested, is removed after 24 hours.With by Examination person's test position skin color, skin pain, test position residue glue situation are Appreciation gist when removing.
Experimental result:
Interpretation of result: can generally increase degree of integration using the hydrocolloid blob of viscose cooperation separation net 3 of formula of the invention, Peel strength by the way that the bearing hydrocolloid dressing of separation net 3 is not added known to sample and the result of contrast sample, which is significantly greater than to have added, is isolated The bearing hydrocolloid dressing of net 3, the bearing hydrocolloid dressing degree of integration that separation net 3 is in addition not added are poor.
The use of separation net 3, which can reduce the damage to the surface of a wound and reduce hydrocolloid, remains on the surface of a wound due to swelling On.
Experiment two, hydrocolloid blob of viscose optimization experiment:
Embodiment 1: by 50 parts of rubber elastomer SIS, 8 parts of terpene resins, 30 parts of sodium carboxymethylcelluloses and 12 parts of mineral Oil is placed in the mixer of 20r/min, in 200 DEG C of mixing 60min, obtains hydrocolloid blob of viscose 1.
Embodiment 2: by SEBS55 parts of rubber elastomer, 5 parts of terpene resin, 25 parts of gelatin, 15 parts of mineral oil are placed in 20r/ In the mixer of min, in 200 DEG C of mixing 60min, hydrocolloid blob of viscose 2 is obtained.
Embodiment 3: by SEBS55 parts of rubber elastomer, 5 parts of terpene resin, 25 parts of gelatin, 15 parts of mineral oil are placed in 20r/ In the mixer of min, in 200 DEG C of mixing 60min, hydrocolloid blob of viscose 3 is obtained.
Embodiment 4: by SIS53 parts of rubber elastomer, 10 parts of tackifier Petropols, macromolecule absorption material pectin 18 Part, it 19 parts of softening agent mineral oil, is placed in the mixer of 20r/min, in 200 DEG C of mixing 60min, obtains hydrocolloid blob of viscose 4.
Above-mentioned blob of viscose is put into tabletting forming machine, it is tabletted under the same conditions and coated on PU film, be made 10 × The hydrocolloid film of 10cm size, referring to " the 4th part of YY/T1293.4-2016 contact Wound dressing: bearing hydrocolloid dressing " into Row test.
Liquid inhales penetration for 24 hours Hold stickiness Peel strength PH value
Blob of viscose 1 3.4g < 2.5mm 2.2N 5.3
Blob of viscose 2 4.7g < 2.5mm 4.5N 5.4
Blob of viscose 3 4.1g < 2.5mm 3.7N 4.8
Blob of viscose 4 5.2g < 2.5mm 3.4N 5.7
Interpretation of result: 4 liquid of blob of viscose suction penetration is best, and peel strength is moderate, and pH value is best, excellent in comprehensive performance In other samples, therefore select the formula of blob of viscose 4 for optimal selection, i.e., by SIS53 parts of rubber elastomer, tackifier Petropols 10 parts, 18 parts of macromolecule absorption material pectin, 19 parts of softening agent mineral oil.
Experiment three, separation net optimization experiment;
Using hydrocolloid film obtained by hydrocolloid blob of viscose optimization formula as substrate, the association of separation net 3 and hydrocolloid is tested The same sex.
Embodiment 1: by pressure roller by aperture be 260 μm, 150 μm of thickness, percent opening be 50% nylon wire and hydrocolloid Bonding is integrated.
Embodiment 2: by aperture being 260 μm by pressure roller, 150 μm of thickness, the PET net and hydrocolloid that percent opening is 50% are viscous It is integrated.
Embodiment 3: by aperture being 260 μm by pressure roller, 150 μm of thickness, the PES net and hydrocolloid that percent opening is 50% are viscous It is integrated.
Embodiment 4: by aperture being 100 μm by pressure roller, 80 μm of thickness, the nylon wire and hydrocolloid that percent opening is 53% are viscous It is integrated.
Embodiment 5: by pressure roller by aperture be 500 μm, 280 μm of thickness, percent opening be 43% nylon wire and hydrocolloid Bonding is integrated.
Interpretation of result: through embodiment 1-3 it is recognised that under conditions of same apertures, percent opening, thickness, nylon every The pliability of off-network 3 is best.Comparative example 1,4, the nylon wire of 5 three kind of different size are it is found that the too small then screen cloth of mesh and glue The binding force of layer is poor, screen cloth defective tightness in conjunction with glue-line.If selecting large aperture, thicker screen cloth, it may appear that when bending The phenomenon that screen cloth and glue-line disengage.To sum up, preferred 3 material of separation net is nylon wire, and screen cloth parameter is 260 μm, 150 μ of thickness M, percent opening 50%.
Comprehensive Experiment two and experiment three are it is found that according to SIS53 parts of rubber elastomer, and 10 parts of tackifier Petropols, high score 18 parts of sub- absorbing material pectin, 19 parts of the softening agent mineral oil hydrocolloid blob of viscoses prepared and parameter are 260 μm, 150 μm of thickness, are opened The nylon wire that porosity is 50% has optimal synergistic effect.
The present invention cooperates the formula raising of hydrocolloid blob of viscose to propose 2 degree of integration of hydrocolloid glue-line again by the way that nylon wire is arranged Height, thus avoid there is a phenomenon where glue-line breakage, be swollen rupture;Hydrocolloid glue-line 2 can be prevented by the setting of separation net 3 and is done The dry surface of a wound is adhered, and thus can reduce the damage when removing bearing hydrocolloid dressing to the surface of a wound.
The basic principles, main features and advantages of the invention have been shown and described above.The technical staff of the industry should Understand, the above embodiments do not limit the invention in any form, all obtained by the way of equivalent substitution or equivalent transformation Technical solution is fallen within the scope of protection of the present invention.
