Medical use surgical fixing bandage, finger cot and preparation thereof

Abstract

The medical bandage and finger stall are produced with thermoplastic caprolactone in 30-100 wt% and thermoplastic polymer in 0.5-50 wt%. The production process includes composite extruding of the mixture material in an extruder to form strip, weaving the strip into bandage, and winding the strip or bandage onto mold to form finger stall. The medical bandage and the finger stall may be softened in hot water at 65 deg.c to obtain excellent plasticity for fitting body shape and settled fast at room temperature to maintain the shape and have relatively high use strength. The present invention may be used in fixing fracture part and restoring.

Description

technical field [0001] The invention relates to a bandage for medical surgery fixation, a finger cot and a preparation method thereof, in particular to a low-temperature thermoplastic bandage for medical surgery fixation, a finger cot and a preparation method thereof. Background technique [0002] Bandages for medical and surgical fixation mainly include non-plastic splints made of wood, metal or plastic, plaster bandages, polyurethane bandages, etc. [0003] Non-plastic splints are difficult to cling to human body parts, and cannot achieve a good fixation and support effect; the disadvantages of plaster bandages are that they are heavy, inconvenient for patients to move, poor in air permeability, and poor in X-ray transmission; polyurethane bandages are light in weight and have good air permeability Good, but the storage period before use is short, and the operation is troublesome; the low-temperature thermoplastic medical surgical orthopedic plate with vinyl acetate resin ...

AI Technical Summary

Problems solved by technology

[0003] Non-plastic splints are difficult to cling to human body parts, and cannot achieve a good fixation and support effect; the disadvantages of plaster bandages are that they are heavy, inconvenient for patients to move, poor in air permeability, and poor in X-ray transmission; polyurethane bandages are light in weight and have good air permeability Good, but the storage period before use is short, and the operation is troublesome; the low-temperature thermoplastic medical surgical orthopedic plate with vinyl acetate resin as the main raw material is cheap and easy to manufacture, but the plasticity is poor, so a thermoplastic polycaprolactone was developed. Low-temperature thermoplastic surgical fixation bandage and finger cot as main raw material

[0004] Thermoplastic materials currently containing thermoplastic polymers for medical fixation, such as natural resin orthopedic materials, such as the Chinese patent application whose publication number is CN9910817.6, and ethylene-vinyl acetate copolymer resin self-adhesive fixing materials, such as the publication number is CN00111732.7 Chinese patent applications for poly-trans-isoprene splints, such as the Chinese patent application with publication number CN8710140.7, etc., although they can be applied to fracture fixation, they have low thermal deformation temperature, low strength, and use Deformation is easy to occur in the center, especially for large bone injuries, it cannot fix the effect or the price is expensive, and the source of materials is difficult.

For example, the publication number is CN8510027.8, and the technology disclosed in the Chinese patent titled "Thermoplastic splint formula and its processing technology" has a minimum thermal deformation temperature of 37°C, and it deforms when it is slightly heated. The use strength is low and the impact is reliable. sex
