Abstract
The invention relates to a medical splint material of a warp-knitted structure. Low-melting-point artificial fiber is adopted solely or cooperatively with common conventional chemical fiber for knitting, and matched warp-knitting structures are adopted for knitting on a Tricot high-speed warp knitting machine according to different raw selecting and feeding modes. The medical splint material can be stored at normal temperature or low temperature; the medical splint material can be quickly softened and freely deformed according to needed shapes when temperature is higher than certain critical temperature, namely melting temperature of the low-melting-point artificial fiber, the medical splint material can be quickly hardened to form a splint material having certain strength and air permeability when environment temperature is lowered to be lower than the critical temperature after deformation, and the medical splint material is reusable.
Description
Technical field
The present invention relates to rigidity can be become under a kind of medical splint material of warp knit structure, especially a kind of uniform temperature
The flexible warp-knitted fabric of clamping plate, belongs to textile technology field.
Background technology
Medical splint, that is, orthopaedics external fixation system.From the point of view of medical angle, medical splint material should have certain
Intensity, toughness and breathability, weight are more light better, it is therefore desirable to threw X-ray etc..Material is fixed outside the orthopaedics being widely used earliest
Material is Gypsum Fibrosum and plank, it is difficult to meet these requirements.Gypsum material is easy to moulding, with good forming ability, is dried
There is enough intensity afterwards, and raw material sources are wide, price is low, for a long time preferred material fixed always outside orthopaedics.But
Gypsum Fibrosum is heavier, and airtight, can make troubles to the life of patient, delay treatment rehabilitation；Gypsum Fibrosum can not be penetrated through X
Line, it has not been convenient to which doctor is checked to the state of an illness of patient；Gypsum Fibrosum meets water dissolution, and hardening time is long, complex operation, and intolerant to
Mill, easily powders away, not easy to maintain, and dismounting is also inconvenient.Small splint immobilization is then referred to binder plank, bamboo clappers or plastics etc.
Boards wall made by material remains stationary fracture site on limbs, is beneficial to fracture site healing.This therapy
Suitable for all kinds of fracture.But plintlet is substantially planar structure, it is difficult to be adapted with the shape of human body limb；Wooden plintlet
It is general harder, almost there is no elasticity, and poor air permeability, it is impossible to which the comfortableness for meeting patient is required.Modern composite medical clamping plate
Mainly it is combined into water cure or heat reactive resin by multi-layered textile product, outside cladding jacket layer is formed, and its performance mainly depends on
In textile and the structure and performance of resin.At present, polyurethane being adopted water cure laminated more, clamping plate need to be put using before
Certain hour is soaked in warm water, then water is extruded, appearance is dried, then applied in patient injury, more using in-place forming
Mode.Such clamping plate before not breaking a seal and enabling is put down very soft, but is packed opening, soak, be fixed on patients with fractures position
Afterwards, a moment is slightly spent, laminated is solidifying and setting, so as to play fixation, easy to use.At heat cure laminated heat
In moulding state, after cooling, become hard again, can Reusability.General is in soft autohension state at 65-70 DEG C, at about 50 DEG C
It is presented below for rigid sheet.The common resins of such clamping plate are polyolefin, polyamide and polyester, can be not added with base fabric.Although
Modern laminated has a great progress, but which is difficult that molding is round and smooth, and breathability is also an insoluble problem.
Patent application CN00242274.3 to adapt to be similar to the limbs profile of circle, reduces cleat design camber
Local compression of the clamping plate to skin；And patient is made using with certain elastomeric material for playing extensional energy as binding fixing bundle band
Wear comfort increases.
Patent application CN00243168.8 discloses a kind of plintlet, and whole clamping plate is divided into several parts, each section it is little
Clamping plate is placed in a polypropylene sack, and each is connected by belt between sack equipped with plintlet.Traditional clamping plate is compared, this
Plant clamp region simple, it is convenient and easy, it is difficult to loosen.
Adjustable integrated splints for first-aid disclosed in patent application CN200320121357.2, is to be adapted to limbs shape,
Monoblock clamping plate is divided longitudinally into three pieces along limbs, clamping plate outer lining muslin material, is connected by adhesive tape per block.This clamping plate can be according to limb
Body thickness and the state of an illness adjust width and relative position between clamping plate.
With the development of Modern Composite Materials, the exploitation of new medical clamping plate also makes remarkable progress.Patent application
Macromolecular splint disclosed in CN01245891.0, is by positioned at middle ethene-vinyl acetate copolymer（EVA）Self-adhesive layer and position
In the high intensity polycaprolactone on two surfaces（PCL）Self-adhesive layer three ply board bluk recombination is formed, and can soften random-shaping, often at 70 DEG C
Warm 4-6 minutes are hardened.This macromolecular compound clamping plate does not contain textile substrate.
The clamping plate that patent application US10/319224 is introduced includes antibiotic layer, wet sensitive cured layer and outer layer.Antibiotic layer is adopted and is added
The multilamellar nonwoven polypropylene fabric of antibacterial is added, solidified resin is still wet sensitive curable polyurethane, cloth base is woven dacron, jacket layer is adopted
With the microfibre fabric of chinlon and terylene.This clamping plate is water cure type.
Can be seen that by above Developments, the multiplex laminated of modern medical splint instead of traditional Gypsum Fibrosum and wood
Plate.These Fabric composites or the cleat shapes adaptability without fabric macromolecular material are not good enough, and fold easily occurs in turning；
The hardening time of wet-cured type clamping plate is oversize, and the autohension temperature of thermohardening type clamping plate is higher, can bring discomfort to patient；
For existing these clamping plates, good breathability is also a problem.
The content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art, for existing medical splint material shape adaptability
It is bad, breathability not enough, the defect such as patient comfort is poor, there is provided a kind of medical splint material of warp knit structure, processing technology
Simply, conformability is strong, and itself has certain air permeability.
According to the technical scheme that the present invention is provided, a kind of medical splint material of warp knit structure is characterized in that：Using eutectic
Point staple fibre or low melting point staple fibre and common chemical fibre coordinate braiding warp knit eyelet stitch structure, the medical splint material
When more than critical temperature, softening transform forms required form, solidify to form hard medical clamp when being less than critical temperature after deformation
Plate；
The low melting point staple fibre adopts low melting point polyester fiber, low melting point polyamide fiber, low melting point polyolefin fiber, hydroxyl
Methyl cellulose cellulose fiber, alginate fiber, glue protein matter fiber or chitin fiber.
Further, the medical splint material all using low melting point staple fibre when, medical splint materials microstructure
