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 technical field of medical apparatus processing, especially a kind of working method of medical puncture needle needle tubing outside surface mark scale marks.
Background technology
Some medical puncture needle now as the needle tubing of the outer puncture needle of hard fiber crops is fixed into one by metal tube and macromolecular material needle stand, is provided with scale marks on needle tubing surface, can allow medical personnel puncture to patient time, and the degree of depth of grasp puncture promptly and accurately.The puncture needle using now prints scale marks on needle tubing surface with marking method conventionally, but this needle tubing scale marks with marking method printing, storage period one is long, will desalinate, even do not see scale marks, thereby impact is used, and makes doctor can not grasp depth of needle and position.
Summary of the invention
The object of the invention is the deficiency in order to solve above-mentioned technology, a kind of working method that can make the medical puncture needle needle tubing scale marks that the scale marks marking on needle tubing never desalinates is provided.
This scheme is like this design, the first step, and processing plastic sleeve pipe, puts into tube cutting tool by plastics tubing, the scale marks size of mark as required, thus calculate the size of required plastics tubing, adjust tube cutting tool, and cut, obtain multiple plastic casings; Second step, is enclosed within sleeve pipe segmentation on needle tubing, only exposes the size part that needs mark scale marks, makes to combine closely between sleeve pipe and the needle tubing of quilt cover, and liquid can not enter the junction of sleeve pipe and needle tubing; The 3rd step, Phosphating Solution preparation, the concentration of chromium trioxide 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; The 4th step, needle tubing phosphating reaction, has the needle tubing of sleeve pipe to be immersed in Phosphating Solution in cover, when phosphatization, heats, and temperature is 80-100 DEG C, and the time is 2-4 hour; The 5th step, rinses, and first rinses with clear water, then soaks, with hot-water soak 2-3 hour; The 6th step, removes sleeve pipe by the above-mentioned needle tubing processing.
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 total amount of liquid that add water reach 1500mL.
As preferably, 95 DEG C of described phosphatization temperatures, the reaction times is 3.2 hours.
Be to obtain by chemical reaction according to the scale marks marking on above-described medical puncture needle needle tubing, thereby be difficult for removing, be also difficult for fading, this needle tubing is placed for a long time, and scale marks also can not be desalinated.And the features such as the needle tubing that the present invention has is easy to operate, obtain has extended work-ing life, bright in color and good brightness.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
