Attached drawing 2 is refer to, Fig. 2 is the dimensional structure diagram of human body ear primary structure.The human body ear is main
Structure includes human body ear 2, concha auriculae alveolus 21, cymba 22, duct 23.
It should be noted that：Concha auriculae alveolus 21 and ear of the auricle portion 11 with human body ear 2 in the delivery device housing 1
First ship shape is adapted；12 form of duct portion in the delivery device housing 1 follows each one 23 internal diameter of duct, curvature；It is described
Delivery device housing 1 rebuild with the Digital Three-Dimensional of Medical Imaging inspection and 3D printing technique is integrally formed, flow is as follows：
1) medical image data is obtained：
The imageological examinations such as patient's routine ear CT unenhanced (thin layer 2mm), ear MRI be unenhanced, obtain duct morphology number
According to saving as the identifiable form of medical image, be uploaded to host computer.
2) delivery device housing threedimensional model is generated：
First, host computer generates the cloud data of ear according to the ear image received, and cloud data is converted into compiling
Collecting grid threedimensional model, (palpus dept. of radiology provides the dimension information of the two-dimension picture image contour of device therefor and adjacent two pictures
Dimension information, can be formed with material object 1：1 rebuilds).Secondly, using 3 d modeling software Rhino 3D, according to each one auricle
With duct characteristic simulation delivery device model, anthelix inferior horn, anthelix, antitragus, tragus incisura, tragus, concha auriculae alveolus are cut
The part surrounded with crus helicis, makes auricle portion 11 and each one the 22 shape phase of concha auriculae alveolus 21 and cymba of delivery device housing 1
Adapt to；Delivery device housing duct portion 12 is set to stretch into the about 1.5cm-1.8cm of duct 23, form follows each one duct internal diameter, curvature.Profit
Smooth surface processing is carried out with smooth instruments, obtains the blank of the ear cavity shell threedimensional model of delivery device.
3) interior spatial structure is built：
Pumping shell is carried out to model using 3 d modeling software Rhino 3D, in order to leave foot to replaceable built-in traditional Chinese medicine powder bag
Enough spaces, and ensure that housing has enough intensity, take out thickness of the shell is advisable with 0.5mm-0.8mm, i.e., the shell of delivery device housing 1 is thick
It is arranged to 0.5mm-0.8mm.Concha auriculae alveolus volume and duct aperture are gone out by software survey calculation, according to survey calculation as a result,
Determine to lead position, the size of medicine mouth 111 and stomata 121.Structure leads medicine mouth and stomata characteristics in Rhino 3D softwares, described to lead
Medicine mouth 111 should be located at the center of concha auriculae alveolus 21 in 1 auricle portion 11 of delivery device housing, and shape is circular, diameter about 1cm.The gas
Hole 121 should be located at 1 duct portion of delivery device housing, the 12 ends position opposite with eardrum, and shape is circular, diameter about 0.4cm-
0.6cm。
4) printing manufacture housing and surface treatment procedure：
Model treatment result is imported in 3D printer, delivery device housing 1 passes through 3D printing technique one with silica gel material
Shaping.The surface of shell produced using sanding and polishing equipment air exercise printing is handled.
In a preferred embodiment, design and lead medicine mouth 111 it is matched capping 112, it is described capping 112 should with it is described
Lead 111 shape of medicine mouth to be consistent, can fill in and lead medicine mouth 111 and collectively form confined space.The design is easy to replaceable traditional Chinese medicine powder bag
Insert delivery device intracavitary and closure is good.
In a preferred embodiment, 121 surface of stomata of 1 duct portion of delivery device housing, 12 end covers one layer every medicine
Guard 122, such as Fig. 4, to dissipate medicine gas, the product altered are walked using Chinese medicine fragrance stimulates ear arteries and veins, and unimpeded ear key, reaches treatment effect
Fruit.
Embodiment 2
Attached drawing 9 is refer to, Fig. 9 is the dimensional structure diagram of another ear key delivery device based on 3D printing of the invention,
The present embodiment is substantially the same manner as Example 1, its difference is, 1 surface of delivery device housing in the present embodiment, which is equipped with, to hang
Hook 3；The hook 3 is silica gel material, and head end is circle, and 1 surface of delivery device housing is fixed on by way of silica gel absorption；
It is described by being fixed with hook 3 on 1 surface of delivery device housing, hook 3 can be placed in ear by patient while delivery device is worn
Piece outer periphery, and by way of silica gel absorption, hook 3 is close to the skin around ear, good fixation is played,
And silica gel material is softer, patient will not feel have Le to feel, and improve the comfort level of wearing；Ear key administration in described the present embodiment
Device, the characteristics of shaping by itself by 3D printing, the external auditory meatus perfection with patient agrees with, and is not easy to drop, and recycles consolidating for hook 3
Determine mode, play dual firm effect, enable ear key delivery device being fixed on patient's ear steadily, do not influence patient and control
While treatment, the activity of patient is also more convenient for；The hook 3 is that delivery device shell is fixed on by way of silica gel absorption
