Abstract
The invention discloses the technical field of medical device processing, and particularly provides a processing method for a medical puncture needle tubing scale mark, solving the shortcomings of the prior art. The processing method for the medical puncture needle tubing scale mark has the capacity of permanently preventing the scale line marked on the needle tubing from fading. The processing method comprises the following steps of processing a plastic sleeve, sleeving the sleeve on the needle tubing, preparing a phosphating solution, phosphating the needle tubing and flushing and the like, so as to obtain the needle tubing with the scale line. The processing method has the characteristic of being simple in process, convenient to operate; and the method is widely applied to marking the scale mark on the metal puncturing needle tubing.
Description
Technical field
The present invention relates to a kind of medical apparatus machining technology, especially a kind of working method of medical puncture needle needle tubing outside surface mark scale marks.
Background technology
Present some medical puncture needle is fixed into one like the needle tubing of the outer puncture needle of hard fiber crops by metal tube and macromolecular material needle stand, and the needle tubing surface is provided with scale marks, in the time of can letting medical personnel that patient is punctured, and the degree of depth that grasp is promptly and accurately punctured.The puncture needle that uses now prints scale marks on the needle tubing surface with marking method usually, but this needle tubing scale marks with the marking method printing, storage period one is long; Will desalinate; Even do not see scale marks, thereby the influence use makes the doctor can not grasp depth of needle and position.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, a kind of working method that can make the medical puncture needle needle tubing scale marks that the scale marks that marks on the needle tubing never desalinates is provided.
This scheme is like this design, the first step, and the processing plastic sleeve pipe is put into the Pipe Cutting frock with plastics tubing, the scale marks size of mark as required, thus calculate the size of required plastics tubing, adjustment Pipe Cutting frock, and cut, obtain a plurality of plastic casings; Second step was enclosed within the sleeve pipe segmentation on the needle tubing, only exposed the size part that needs the mark scale marks, made between the needle tubing of sleeve pipe and quilt cover to combine closely, and liquid can not get into the junction of sleeve pipe and needle tubing; The 3rd step, the preparation of phosphatization liquid, the chromium trioxide strength of solution is 4～6%, and phosphoric acid solution concentration is 8～12%, and sulphuric acid soln concentration is 30～40%, and all the other add water, to total amount of liquid 1500mL; In the 4th step, the needle tubing phosphating reaction will be with the telescopic needle tubing and be immersed in the phosphatization liquid, heat during phosphatization, and temperature is 80-100 ℃, and the time is 2-4 hour; In the 5th step, flushing rinses with clear water earlier, soaks then, with hot-water soak 2-3 hour; In the 6th step, the above-mentioned needle tubing that processes is removed sleeve pipe.
As preferably, the concentration of described chromium trioxide is 4.5%, phosphoric acid solution concentration is 9%, and sulphuric acid soln concentration is 37%, and all the other add the total amount of liquid of water and reach 1500mL.
As preferably, 95 ℃ of described phosphatization temperatures, the reaction times is 3.2 hours.
Scale marks according to marking on the above-described medical puncture needle needle tubing is resulting through chemical reaction, thereby is difficult for removing, and also is difficult for fading, and this needle tubing is placed for a long time, and scale marks can not desalinated yet.And characteristics such as the needle tubing that the present invention has is easy to operate, obtain has prolonged work-ing life, bright in color and good brightness.
