Abstract
The invention discloses a method for producing a medical dressing with an X ray developing substance on the surface, comprising the following steps in turn:(1) preparing an X ray developing paste; (2) directly coating the prepared X ray developing paste on the surface of the medical dressing used as a parent material in printing or die coating manner; (3) drying; (4) curing, so as to solidify the X ray developing paste to form the X ray developing linear substance. By printing or coating the X ray developing linear substance formed by settling the X-ray developing linear substance paste on the surface of the medical dressing, the medical dressing has the advantages of higher firmness, shorter time for finishing the products, higher manufacturing efficiency, free control of the shape, size and gap of the X ray developing sheet, and applicability to mass production with multiple varieties.
Description
Technical field
The present invention relates to medical dressing, especially relating to a kind of surface has medical dressing of X-ray development thing and preparation method thereof.
Background technology
Be used for performing the operation hemostasis, suck blood or the medical dressing of body fluid, comprise medical degreasing sterilization gauze, medical degreasing sterilization non-woven fabrics etc., be a kind of very dangerous accident if be left on accidentally in the human body.Must in time find and remove, otherwise sb.'s illness took a turn for the worse even death can to cause the operation receiveing person.Therefore, the medical dressing that is used for performing the operation all adopts the medical dressing that contains X-ray development thing, and this medical dressing can develop when x-ray scanning, can accurately be found in operation receiveing person's body and locate, so that in time remove.The existing manufacture method that contains the medical dressing of X-ray development thing mainly is to adopt hot pressing, ultrasound wave mode that the X-ray thing that develops is scalded built in the medical dressing surface, or adopts the mode of making that the X-ray thing that develops is made on the medical dressing surface.
As Chinese invention patent CN1337215A disclosed " X-ray development operation gauze and production equipment thereof ", its X-ray development operation gauze is that the method with cold extrusion, heat cure is coated with one or several silica gel development line on common gauze, and the weight proportion of silica gel development line is: methyl vinyl silicone rubber 20%～40%, barium sulfate 50%～70%, iodine salt 3%～5%, vulcanizing agent 5%～7%.Its defective is: (1) adopts cold extrusion, thermal curing methods, and low to the adhesion strength of fiber, peel strength is lower; (2) silicone rubber relies on extrusion modling, and X-ray development thing shape is limited by mould, generally can only be successive bar shaped or sheet shape, other change of shape difficulty, molding bar fixed fiber will be by hot pressing, and be subjected to hot pressing aftershaping bar easy deformation, influences X-ray developer sheet good looking appearance; (3) the molding bar must put on the base material continuously, and consumptive material is bigger, can't adapt to the spike that is widely used in local small size at present and develop; (4) silica gel has oil absorption, easily pollutes, and relative intensity is lower, ruptures easily when pullling, and Asia and price are higher." spun-laced nonwoven fabric and the production method thereof that contain X-ray development thing " of Chinese invention patent CN1329579C bulletin and for example, its spun-laced nonwoven fabric that contains X-ray development thing is in the cross lapping operation one or more than one X-ray development things to be sprayed in the fleece of spun-laced nonwoven fabric, described X-ray development thing is wire or zonal X-ray development line, is that X ray absorbing material with liquid state sprays in the stroke of lapping and is frozen into X-ray development line.Its defective is: need the big weight additional of configuration, the cost height is difficult to guarantee nontoxic production; If the resin thing that develops is embedded between the thin type non-woven fabrics fiber, the peel strength that obtain, difficulty is just very big.
In addition, textile printing with mode of printing formation pattern on fabric comprises that stencilling stamp, screen printing, drum-type ROTARY SCREAM PRINTING, transfer printing and polychrome drench methods such as dye transfer flower, wherein screen printing derives from the stencilling stamp, beginning is by manual operations, progressively move towards semi-automatic, full automation, developed into cylinder by flat screen type again afterwards, yet not seeing as yet so far has the report that forms X-ray development line on hospital gauze, non-woven cloth fabric surface with above-mentioned mode of printing and spraying method.
