Embodiment 1

[0036] Such as Figure 1 to Figure 4 As shown, the neonatal auricle orthosis includes a base 10 and an upper cover 20 matched with the base 10. The base 10 includes an auricle covering part 12 for covering the outer auricle, and the auricle covering part 12 is close to the side of the root of the ear. The connecting piece 11 is connected, and a space for accommodating the upper cover 20 is left in the middle of the auricle covering part 12 . The upper cover 20 is provided with a plurality of ventilation holes 21 , and the auricle covering part 12 is provided with a plurality of through holes 14 . It is breathable and makes the wearer comfortable. The base 10 is the base 10 made of silica gel, and the upper cover 20 is the upper cover 20 made of silica gel. Made of silicone, it will not form hard pressure on the auricle and is comfortable. The base 10 is provided with a fixing device for fixing the upper cover 20, and both the base 10 and the upper cover 20 conform to the an...

Embodiment 2

[0056] Such as image 3 As shown, the neonatal auricle orthosis and its manufacturing method, other structures are the same as in Embodiment 1, the difference is that the fixing device is a baffle 13, and the auricle covering part 12 extends out of the baffle 13 in the direction of the upper cover 20 . There are three blocking pieces 13 , and the three blocking pieces 13 are evenly distributed on the auricle covering portion 12 . The connecting piece 11 is integrally formed with the auricle covering part 12 . It is convenient to fix the upper cover 20, and it is not easy to fall out of the base 10 when wearing it.

Embodiment 3

[0058] Such as Figure 5 As shown, the neonatal auricle orthosis and its manufacturing method, other structures are the same as those in Embodiment 1 or 2, the difference is that: the periphery of the connecting piece 11 is also provided with a 3M seam-free tape 15. The 3M seam-free tape 15 is A breathable adhesive tape, which is composed of non-woven backing and pressure-sensitive adhesive, and is attached with elastic fiber to strengthen the tension resistance. Secure the auricle to the head.

Abstract

The neonatal auricle orthosis of the present invention comprises a base and an upper cover matched with the base, the base includes an auricle covering part for covering the outer auricle, and the side of the auricle covering part close to the root of the ear is connected with a connecting piece, and the ear There is a space for accommodating the upper cover in the middle part of the cladding part of the pinna. The orthotic can be used for correction of all types of auricle deformities. The manufacturing method of the newborn auricle orthosis of the present invention comprises the following steps: Step 1, Data acquisition and reverse modeling: Step 2. Adjust the parts of the deformed auricle data that need to be corrected according to the normal auricle data and reverse modeling: Step 3. Draw the baffles of the base, the through holes and the ventilation holes of the upper cover: Steps 4. Use a 3D printer to print out the mold of the auricle orthosis: Step 5. The medical silicone auricle orthosis is poured into shape. This manufacturing method is designed and manufactured in combination with the actual situation of the auricle shape of newborns in China. It is customized according to different patients, and the size is accurate , comfortable to wear.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a newborn auricle orthosis and a manufacturing method thereof. Background technique [0002] Ear deformities are very common in clinical practice. According to the statistical data of Japanese newborns, it is 55.2%. It is often complicated with craniofacial congenital malformation syndromes such as dysplasia of the first and second cheek arches, and is caused by developmental deformities or changes in mechanical structures. The treatment of ear deformity is preschool surgery, which has cartilage deformation, high recurrence rate, and invasiveness, and the comprehensive evaluation risk is high. In 1984, Japanese scholars Matsuo K and Hirose T first proposed in the American Journal of Prosthetic and Reconstructive Plastic Surgery PRS to correct ear deformities through non-surgical treatment in the neonatal period. However, due to the complicated operation and irregular corr...
