Description
Technical Field
The invention relates to the technical field of medical instrument processing, in particular to a method for manufacturing puncture needle scale marks.
Background
The needle tube of the hard anesthesia external puncture needle is formed by a metal tube and a high polymer material needle seat through injection molding, scale marks are arranged on the surface of the needle tube, and the function of the scale marks is to accurately judge the puncture depth when medical personnel puncture patients so as to achieve the purpose of accurate puncture.
As shown in fig. 1, in the puncture needle used at present, scale marks are printed on the surface of the needle tube by a marking method, the existing scale marks are a plurality of circular grooves, the distance between adjacent circular grooves is 5mm, and the like, and the scale marks need to be converted according to the depth of the puncture needle at the position combined with the circular grooves to judge the insertion distance, so that a doctor cannot make a quick response in the puncture process, and even a puncture accident can be caused if the doctor makes a mistake in the conversion.
Disclosure of Invention
The invention aims to provide a method for manufacturing puncture needle scale marks, which enables a doctor to quickly and accurately read the puncture insertion depth by a mode of distinguishing the number of the marks in the counting length and the obvious display of a recognition color layer.
The technical purpose of the invention is realized by the following technical scheme:
a manufacturing method of puncture needle scale marks comprises the steps that in the first step, N counting lengths are marked in sequence in the length direction of the outer wall of a needle tube, wherein N is a positive integer, the outer wall of the needle tube comprises a fine annular groove and a coarse annular groove which are polished on the outer wall, and a fine annular groove, a coarse annular groove, a fine annular groove thickening annular groove, a double-coarse annular groove and a double-fine annular groove are sequentially polished at unit intervals from the position of a needle point to form counting lengths of five counting unit intervals; secondly, processing the plastic pipe sleeves, putting the plastic pipes into a pipe cutting tool, counting unit intervals on the length according to needs, calculating the size of the needed plastic pipe, adjusting the pipe cutting tool, and cutting to obtain a plurality of plastic pipe sleeves; thirdly, sleeving the pipe sleeve on the needle tube in sections, and only exposing the fine ring groove and the coarse ring groove to enable the pipe sleeve and the sleeved needle tube to be tightly combined; fourthly, coating identification color layers in the fine ring groove and the coarse ring groove; and fifthly, removing the pipe sleeve from the processed needle tube, and scraping the identification color layer attached to the outer wall of the needle tube by using a scraper.
By adopting the technical scheme, N can be 1 or 2 or 3 or 4 or 5 and the like, and the unit spacing can be 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9 mm or 10 mm.
1 unit spacing is a small counting unit;
1 count length is one large unit of count, 1 count is large =5 unit spacing.
In the design, the fine ring groove and the coarse ring groove represent multiples of the counting distance, and the specific relation is as follows:
1 sipe ring groove =1;
1 coarse ring groove =2;
1 coarse ring groove +1 fine ring groove =3;
2 coarse ring grooves =4;
2 thin ring grooves =5;
in general, the puncture needle adopts 2 counting lengths at most for reading.
According to the scheme, the fine annular groove and the coarse annular groove are combined, so that each scale point is obviously distinguished, a doctor can accurately read the insertion depth of the puncture needle, the puncture action is safer, and the puncture accidents are reduced.
The doctor who can see clearly the combined relation of thin ring groove and thick ring groove among the identification chromatograph of this design further makes the doctor can accurate reading puncture needle depth of inserting.
The pipe sleeve prevents the outer wall of the needle tube from being stained with an identification color layer; because the thin ring groove and the thick ring groove are concave, when the scraper cleans the identification color layer accidentally stained on the outer wall of the needle tube, the identification color layer in the thin ring groove and the thick ring groove can not be scraped.
Preferably, the identification color layer comprises a first identification color layer and a second identification color layer;
coating a uniform first identification color layer on the fine ring groove, the coarse ring groove, the fine ring groove and the coarse ring groove, and the double coarse ring grooves; and painting a second identification color layer on the double-thin ring groove.
Through adopting above-mentioned technical scheme, because adopt 1 count length to be big unit in this design, so adopt different discernment chromatograph in two thin ring grooves, the reading is striking and easily distinguish more, and the doctor of being convenient for accurately reads the inserted degree of depth of pjncture needle.
Preferably, the fluorescent powder is added into the identification color layer.
Through adopting above-mentioned technical scheme, the purpose that adds the phosphor powder lies in, when some emergency, for example open-air first aid or circuit system are unstable, when the puncture environment is dim, can be convenient for the doctor after adding the phosphor powder and realize accurate puncture action in dim environment.
Preferably, in the fifth step, after the pipe sleeve is removed, a transparent nano coating is covered on the surface of the needle tube.
By adopting the technical scheme, the nano coating is used for forming a relatively smooth outer membrane on the outer wall of the needle tube, so that the puncture is performed to the injury of human tissues in the puncture process.
Preferably, in the fourth step, after the identification color layer is coated, the puncture needle is placed into the fixture, the hob in the fixture rotates around the fine ring groove and the coarse ring groove in an extruding manner, the identification color layer is embedded into the fine ring groove and the coarse ring groove in a concave manner, and then the puncture needle is taken out of the fixture.
Through adopting above-mentioned technical scheme, the pressfitting of hobbing cutter is in order to discern the chromatograph and can firmly and laminate in thin ring groove or thick ring groove with a sunken mode.
