It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The present invention will be further described with reference to the following examples.
Example one
An adjustable acupuncture needle for chinese medical science according to the present embodiment is shown in fig. 1 to 6: comprises a needle body 1, a needle sheath 2 and a hollow cannula 3; the outer surface of the needle body 1 is provided with a protective layer (not shown in the figure); the needle body 1, the needle sheath 2 and the hollow sleeve 3 are all of inverted convex structures, and the top of the needle body 1 is provided with a cylindrical cap body 4; the thread of the needle body 1 is arranged in the needle sheath 2, the middle part of the lower part of the needle sheath 2 is provided with an annular cavity 5, the annular cavity 5 is communicated with a catheter 6 positioned at one side end of the lower part of the needle sheath 2, the lower part of the needle sheath 2 is connected with a hollow sleeve 3 with an inverted convex structure, the inner wall of the thinner end of the lower part of the hollow sleeve 3 is circumferentially provided with a water outlet hole 7 inclined downwards, and the inner wall of the thinner end of the lower part of the hollow sleeve 3 is glued with a medical sponge 8.
Specifically, the upper part of the acupuncture body is provided with an external thread, and the inner wall of the upper part of the needle sheath 2 is provided with an internal thread groove matched with the external thread. The matching use of the external thread and the internal thread groove not only facilitates the adjustment of the effective length of the needle body 1, but also facilitates the traditional Chinese medicine to carry out the needle operation for the patient; the needle point of the needle body 1 can be conveniently retracted into the needle sheath 2 in the traditional Chinese medicine, and the carrying is convenient; and the acupuncture needle can not be punctured by the needle point when being carried by the traditional Chinese medicine, and is safer to carry.
The protective layer can be, for example, an anti-oxidation layer, an abrasion-resistant layer, or other existing structures with protective effects.
The outer walls of the cylindrical cap body 4 and the upper part of the needle sheath 2 are both longitudinally provided with anti-skid stripes along the circumferential direction. The anti-skid stripes on the outer wall of the cylindrical cap body 4 are convenient for the traditional Chinese medicine to rotate the needle body 1, thereby realizing the adjustment of the length of the needle body 1. The anti-skid stripes on the outer wall of the needle sheath 2 can increase the friction force between the needle sheath and the fingers of the traditional Chinese medicine, thereby facilitating the smooth needle operation of the traditional Chinese medicine and reducing the error rate during the needle operation.
The top of the catheter 6 is in threaded connection with a pipe cap 9 with the outer wall provided with anti-skid stripes, and the catheter 6 is obliquely arranged on the side wall of the lower part of the needle sheath 2. The use of the catheter 6 is convenient for Chinese medicine to inject warm water with proper temperature (close to the body temperature of a patient) into the annular cavity 5 at the lower part of the needle sheath 2, thereby realizing the heating of the needle body 1, reducing the temperature difference between the needle body 1 and the body of the patient and improving the comfort level of the patient when receiving acupuncture treatment.
An annular mounting plate 10 matched with the hollow sleeve 3 is fixedly arranged on the outer wall of the lower part of the needle sheath 2, and an arc-shaped liquid injection port 11 is formed in the top of the annular mounting plate 10. The arc-shaped liquid injection port 11 is convenient for Chinese medical science to inject medical alcohol into the hollow sleeve 3 (keeping the acupuncture needle in a vertical state), and the medical alcohol finally flows onto the medical cotton 8 through the water outlet hole 7 which is inclined downwards and wets the medical cotton 8. In the traditional Chinese medicine, the up-and-down movement of the needle body 1 is controlled by rotating the cylindrical cap body 4, so that the thinner end and the needle point at the lower part of the needle body 1 are fully wiped by medical alcohol in the medical cotton 8, and the effects of scrubbing, sterilizing and disinfecting the surface of the needle body 1 are realized. And the acupuncture needle can be prevented from being directly contacted with the fingers of the traditional Chinese medicine when being scrubbed, so that the probability that the fingers of the traditional Chinese medicine are punctured by the needle tip is reduced. The upper parts of the hollow sleeve 3 and the annular mounting plate 10 are both provided with threaded holes, and the hollow sleeve 3 and the annular mounting plate 10 are connected through a butterfly bolt 12. The use of the butterfly bolt 12 facilitates the mounting and dismounting of the hollow casing 3 and also facilitates the replacement of the medical sponge 8.
The inner diameter of the thicker end of the upper part of the hollow sleeve 3 is equal to the diameter of the thinner end of the lower part of the needle sheath 2, and the inner diameter of the thinner end of the lower part of the hollow sleeve 3 is larger than the diameter of the thinner end of the lower part of the needle body 1. This design ensures that the hollow cannula 3 is in close abutment with the needle sheath 2. The medical cotton 8 is attached to the outer wall of the needle body 1. The medical cotton 8 can be used for fully scrubbing the needle body 1 so as to achieve the purposes of disinfecting and sterilizing the needle body.
The length value of the thinner end of the lower part of the needle body 1 is less than that of the needle sheath 2 and is greater than that of the thinner end of the lower part of the needle sheath 2. The design ensures that the thinner end of the lower part of the needle body 1 can be completely retracted into the needle sheath 2, and reduces the phenomenon of stabbing the traditional Chinese medicine due to the exposure of the needle point of the moxibustion needle.
Before the acupuncture device is used for acupuncture of a patient, the cylindrical cap body 4 is rotated to enable the needle body 1 to be completely retracted into the inner cavity of the thinner end of the lower portion of the needle sheath 2, warm water with proper temperature (close to the body temperature of the patient) is injected into the annular cavity 5 of the lower portion of the needle sheath 2 through the guide tube 6, and therefore the needle body 1 is heated, the discomfort of the patient during acupuncture is reduced due to the fact that the temperature of the surface of the needle body 1 is low (in cold seasons) and large temperature difference exists between the needle body and the body of the patient when the patient is subjected to acupuncture subsequently, and the comfort of the patient during acupuncture treatment is improved. When carrying out acupuncture, adjust the effective length of needle body 1 through rotating cylindricality cap body 4, the traditional chinese medical science of being convenient for carries on the needle for patient, and traditional chinese medical science has two kinds of operation modes when carrying on the needle for patient: firstly, the left hand vertically holds the needle sheath 2 in a vertical state, and then the needle body 1 directly rotates the cylindrical cap body 4 to move downwards so as to realize the purpose of acupuncture for patients. Secondly, the aim of acupuncture and moxibustion for the patient is realized by holding the anti-skid stripes on the upper part of the needle sheath 2 and rotating the anti-skid stripes.
After acupuncture is finished, the traditional Chinese medicine injects medical alcohol into the hollow sleeve 3 through the arc-shaped injection port 11 (the acupuncture needle is kept in a vertical state), and the medical alcohol finally flows onto the medical cotton 8 through the water outlet 7 which is inclined downwards and wets the medical cotton. In the traditional Chinese medicine, the up-and-down movement of the needle body 1 is controlled by rotating the cylindrical cap body 4, so that the thinner end and the needle point at the lower part of the needle body 1 are fully wiped by medical alcohol in the medical cotton 8, and the effects of scrubbing, sterilizing and disinfecting the surface of the needle body 1 are realized. And the acupuncture needle can be prevented from being directly contacted with the fingers of the traditional Chinese medicine when being scrubbed, so that the probability that the fingers of the traditional Chinese medicine are punctured by the needle tip is reduced. Of course, the method can also be carried out before acupuncture to realize the work of sterilizing and disinfecting the acupuncture needle, thereby ensuring that the surface of the acupuncture needle is cleaner and more sanitary.
After the moxibustion needle is used, the traditional Chinese medicine can retract the needle point of the needle body 1 into the needle sheath 2 by rotating the cylindrical cap body 4, so that the phenomenon that the normal use of the moxibustion needle is influenced because the needle point of the moxibustion needle is bent under the action of external force when the moxibustion needle is carried by the traditional Chinese medicine is reduced, and a certain protection effect on the needle point of the moxibustion needle can be achieved.

s4, filtering the coating crude product obtained in the step S3 by using a fine mesh filter screen, then placing the product into a reaction kettle, setting the temperature in the reaction kettle to be 80 ℃, and then carrying out ultrasonic vibration treatment by using an ultrasonic vibration rod at the frequency of 35KHz until bubbles in the coating crude product are sufficiently expelled out;
and S5, detecting the physical and chemical properties of the coating in the S4, and packaging after the coating is detected to be qualified to obtain the finished product of the anti-aging coating for the medical instrument.
After the finished product of the anti-aging coating is obtained, a protective layer can be formed on the needle body 1 through the existing coating process, the thickness of the protective layer can be 100-120 μm, and the anti-aging performance and the corrosion resistance of the needle body 1 are improved, and the reason is that:
firstly, the anti-aging coating of the embodiment takes the modified waterborne epoxy resin emulsion as a raw material for preparing the coating, and the waterborne epoxy resin emulsion is chemically modified by gamma-methacryloxypropyltrimethylsilane and 2-hydroxy-4-n-octoxybenzophenone; under the action of gamma-methacryloxypropyltrimethylsilane, the epoxy resin and the 2-hydroxy-4-n-octoxybenzophenone are indirectly connected by chemical bonds, so that the modified waterborne epoxy resin emulsion has good ultraviolet resistance, and the aging resistance of the coating is improved. Moreover, the glass flakes and the 2-hydroxy-4-n-octoxy benzophenone are mutually cooperated, so that the thermal expansion coefficient and the bonding thermal stress of the coating prepared by the invention are relatively small, and the phenomenon of 'peeling' of the coating caused by heating is obviously improved.
Secondly, the anti-aging coating of this embodiment selects vinyl bis stearamide, ultramarine blue and zirconium phosphate as raw materials for preparing the coating, wherein the vinyl bis stearamide has a strong affinity for the ultramarine blue and the zirconium phosphate, and polar groups in the molecules of the vinyl bis stearamide firmly adsorb the ultramarine blue and the zirconium phosphate, so that the polar groups are firmly adhered to the surfaces of the ultramarine blue and the zirconium phosphate. And the carbon-hydrogen bond can directionally extend into the external medium to extend, so that the interfacial tension between the surfaces of the ultramarine blue and the zirconium phosphate and the external medium is reduced, the wettability of the ultramarine blue and the zirconium phosphate is obviously improved, the ultramarine blue and the zirconium phosphate can be more uniformly mixed in the coating, and the performance of the prepared coating is ensured. Furthermore, the combination of ultramarine and zirconium phosphate improves the corrosion resistance of the coating obviously.
Thirdly, the anti-aging coating of the embodiment adopts barium petroleum sulfonate, lanolin magnesium soap, dodecenylsuccinic acid and polyhexamethylene guanidine, and the anti-aging coating can remarkably improve the anti-rust performance and the wear resistance of the prepared coating and correspondingly prolong the service life of the coating by matching the barium petroleum sulfonate, the lanolin magnesium soap, the dodecenylsuccinic acid and the polyhexamethylene guanidine according to a certain proportion.
To confirm the excellent properties of the anti-aging coatings, the properties of the commercially available anti-aging coatings (comparative example) from Shanghai paint company and the anti-aging coating prepared in example 2 were tested, respectively, and the data are shown in the following table:
(Note: 1, abrasion resistance of the coating material prepared in example 2 of the present invention was measured in accordance with GB 1768. 2, and heat resistance of the coating material prepared in example 2 of the present invention was measured in accordance with Q/Ez 159-2003.)
As can be seen from the data in the table above, the anti-aging coating prepared by the embodiment has better anti-aging performance, corrosion resistance, high temperature resistance, wear resistance and adhesion performance than the comparative examples. The coating prepared by the embodiment has better integral performance than a proportion, and can effectively improve the ageing resistance and the corrosion resistance of the needle body 1.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the corresponding technical solutions.
