Photosensitive resin fracture bandaging cylinder
Technical field
The present invention relates to medical orthopedic instrument field.
Background technology
As will be appreciated, bony crepitus can be heard when the typical performance of fracture patient is and occurs that abnormal motion, mobile limbs appear in local deformation, limbs etc. after wound.The final purpose for the treatment of fracture makes injured limb restore funcitons to greatest extent.Therefore, in fractures, it is very important that it resets, fixing, three basic principles in functional exercise.
After the reduction of the fracture, because of instability, easy generation is shifted again, diverse ways therefore will be adopted to be fixed in satisfied position, make it heal gradually.Conventional fixing means has: plaster bandage etc., this method, has very high requirement to the wrapping technique of doctor, and dressing time is also long, wastes time and energy.After fixing to fracture patient in this way, Gypsum Fibrosum is also very moist within a period of time, and the Gypsum Fibrosum of humidity represents and not yet hardens, and is very easily out of shape.Therefore it must be waited after wrapping Gypsum Fibrosum to dry (usually needing 24-48 hour).If good Gypsum Fibrosum, by water erosion, not only easily shorten its service life, and affected part wound also easily causes infection.And after plaster fixing, Gypsum Fibrosum is closed, and patient's fracture site is airtight, is unfavorable for the rehabilitation of patient; Fix with this fixing means, also can affect the blood circulation of patient's fracture site, the recovery also affecting patient is taken exercise.
Summary of the invention

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
As shown in Figure 1, 2, photosensitive resin fracture bandaging cylinder, comprises inner core 1, urceolus 2, capping 3; Urceolus 2 is the cylindrical shell of transparent rubber material; Inner core 1 is also the cylindrical shell of quality of rubber materials; Inner core 1 diameter is less than urceolus 2 diameter, and inner core 1 is socketed in urceolus 2, inner core 1 and urceolus 2 centrosymmetry, and inner core 1 length is identical with urceolus 2 length; Be fixedly connected with by capping 3 between inner core 1 outer surface two ends and urceolus 2 inner surface two ends; Be cavity between inner core 1 and urceolus 2, cavity is built with photosensitive resin filling liquid 4.Run through between inner core 1 and urceolus 2 and be provided with equally distributed gas-permeable channels 5.Separate grid 6 is evenly provided with in cavity between inner core 1 and urceolus 2; And in each grid 6, photosensitive resin filling liquid 4 is housed; Be fixedly connected with by grid 6 between inner core 1 outer surface and urceolus 2 inner surface, the through hole by side between adjacent grid 6 is communicated with.Inner core 1 outer surface is mirror surface.Urceolus 2 side is unidirectional inside transparent surface.Be socketed with pre-bed course 7 in inner core 1, pre-bed course 7 length is consistent with inner core 1 length; Pre-bed course 7 inside is provided with cavity, and is evenly provided with the rectangular pipe 8 of semicircle of protrusion in pre-bed course 7, the rectangular pipe 8 of each semicircle and cavity conducting; Pre-bed course 7 two ends all seal setting; Pre-bed course 7 upper end is connected with the flexible pipe 9 with cavity conducting, and flexible pipe 9 other end is communicated with air bag 10; Pre-bed course 7 is quality of rubber materials.
Urceolus 2 is the cylindrical shell of transparent rubber material, when irradiation under ultraviolet ray photosensitive resin filling liquid 4, medical personnel can be facilitated to observe the solidification situation of the quick resin filling liquid 4 of tumbling, facilitate working doctor, make the photosensitive resin fracture bandaging cylinder of most suitable curing molding to patient; Cavity, built with photosensitive resin filling liquid 4, causes polyreaction at once in the irradiation of ultraviolet light, completes solidification, alleviates the work load of medical personnel, saves the working time of medical personnel, alleviates the misery of patient; Inner core 1 and urceolus 2 are quality of rubber materials, can protect the skin of fracture patient, can not cause the skin of fracture patient fray, scratch etc.Run through between inner core 1 and urceolus 2 and be provided with equally distributed gas-permeable channels 5; Make the affected part of fracture patient keep ventilative, avoiding affected part because infecting in airtight affected part of causing, being unfavorable for the rehabilitation of patient; The ventilative rehabilitation being more conducive to patient at any time.Separate grid 6 is evenly provided with in cavity between inner core 1 and urceolus 2; And in each grid 6, photosensitive resin filling liquid 4 is housed, better can make photosensitive resin fracture bandaging cylinder curing molding, be conducive to this device rapid shaping, because of the liquid of the inside to flowing, and photosensitive resin fracture bandaging cylinder not easy-formation or molding not specification can not be affected.Interior tube outer surface is mirror surface; When irradiation under ultraviolet ray photosensitive resin filling liquid 4, light is radiated on inner core 1 outer surface through photosensitive resin filling liquid 4, reflects and continues the quick resin filling liquid 4 of irradiation; Make ultraviolet light repeatedly irradiate like this, make this device complete curing molding fast, save the working time of medical personnel.Urceolus 2 side is unidirectional inside transparent surface; Prevent the UV light permeability urceolus 2 reflected from irradiating on the human skin, ensure the safety of personnel.Be socketed with pre-bed course 7 in inner core 1, facilitate working doctor; Pre-bed course 7 inside is provided with cavity, is evenly provided with the rectangular pipe of semicircle of protrusion, after completing solidification, is conducive to the blood circulation of fracture patient, make patient's rehabilitation faster in pre-bed course 7.
Doctor, when using to fracture patient, first should be inserted in the present invention the fracture site of patient.At this moment pre-bed course 7 is unaerated states, and photosensitive resin 4 is liquid conditions.After doctor packages to patient, compressing gasbag 10 inflates to pre-bed course 7.Cavity in pre-bed course 7 will expand, and is formed inside a pre-bed course 7 and has the rectangular pipe 8 of the semicircle of protrusion.Continue to inflate to pre-bed course 7, cavity continues to expand, because pre-bed course 7 is quality of rubber materials, owing to being subject to the stop of patient skin, at this moment semicircle rectangular pipe 8 will protrude outside pre-bed course 7.It should be noted that to pre-bed course inflation very little to the pressure of fracture patient skin, secondary injury can not be caused to patient, can relievedly use.
Grid 6 is provided with in the cavity of inner core 1 and urceolus 2, through hole by side between adjacent grid 6 is communicated with, photosensitive resin filling liquid 4 is viscous liquid, photosensitive resin filling liquid is by the through hole flowing at a slow speed of grid side, can effectively prevent photosensitive resin 4 liquid from flowing to side, and cause and solidify not molding, or molding is irregular, once curing is completed, photosensitive resin filling liquid 4 inside through hole becomes solid, each adjacent grid can be coupled together, more be conducive to the molding of photosensitive resin fracture bandaging cylinder.After being full of gas to pre-bed course 7, at this moment comprehensively can be irradiated photosensitive resin 4 liquid in grid 6 by ultraviolet light.When it should be noted that the wavelength control of ultraviolet light is between 250-300 nanometer, photosensitive resin 4 liquid could cause polyreaction at once, completes solidification.Because the rectangular pipe of semicircle 8 of pre-bed course 7 is outwardly giving prominence at pre-bed course 7.So semicircle rectangular pipe 7 can extrude inside inner core 1, make the rectangular pipe identical with the rectangular pipe of semicircle 8 that inside inner core 1, formation one is outwardly.The affected part blood circulation of fracture patient can be made like this, be conducive to the rehabilitation of patient.At this moment photosensitive resin 4 fracture bandaging cylinder molding.The flexible pipe 9 be connected on air bag 10 is extracted, exits to pre-bed course 7, and then pre-bed course 7 is withdrawn from.More than use mode of the present invention and explanation.
