Description

Technical Field

[0001] The invention relates to an insertable bilaterally adjustable orthopedic helmet. Background Art

[0002] Orthopedic helmets are primarily used for infants and young children with cranial deformities. Between three and eighteen months of age, these infants experience varying degrees of anomalies in the anterior-posterior or lateral position of their skulls, leading to misalignment or restricted brain growth and development, impacting the development of multiple brain regions and even neurodevelopment. Literature research has revealed that cranial deformities can also affect the development and function of a child's oral and maxillofacial area, otolaryngology, and head and neck muscles. The incidence of cranial deformities in infants is 22% at seven weeks of age and 21% at two years of age. Evidence of adult cranial dysplasia suggests periosteal indentation of the eardrum and significantly weaker hearing on one side compared to the other. Therefore, the use of orthopedic helmets in early cranial correction interventions for infants and young children is crucial not only for their cranial morphology but also for their subsequent health.

[0003] To address the issue of skull deformities in infants and young children, there are currently two types of orthopedic products available both domestically and internationally: the first is a specially shaped pillow used for infants and young children to sleep, but the correction method is completely dependent on the shape of the pillow, and is passive, unable to prevent the infant's sleeping position; the second is an orthopedic helmet provided by professional institutions, which is mainly used for infants aged 4 to 15 months with head shape problems. It is an intervention treatment for growth and development and is widely used. However, the orthopedic helmet is unilaterally adjustable, and there is unpredictability in the correction of stress and deformity in multiple areas of the head. Therefore, the orthopedic helmet of this application is an optimization and improvement of existing products, with significant improvements and enhancements in terms of functionality, and is more reasonable, scientific, and effective for correcting head deformities. Summary of the Invention

[0004] The purpose of the present invention is to provide an insertable bilaterally adjustable orthopedic helmet, which can realize precise adjustment of the increase of head circumference.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] An insertable bilaterally adjustable orthopedic helmet system includes a front helmet and a rear helmet with split structures, with bilateral openings formed near the ears, and adjustment structures are respectively arranged between the front helmet and the rear helmet at the openings above the ears. The orthopedic helmet is divided into an outer layer and an inner lining layer. The outer layer is made of a hard material to provide support for the overall structure, and the inner layer is made of a softer material to ensure the comfort of the user. The adjustment structure includes side opening grooves on the front helmet and the rear helmet on both sides of the opening, the side opening grooves are in an inverted T shape, and the side opening grooves are arranged on the outer layer of the orthopedic helmet. A front rack slide is provided at the rear of the two opposite side walls of the groove of the side opening groove unit at the front of the helmet, and the front rack slide is provided at the rear of the two opposite side walls of the groove. The tooth shape is inclined forward, and rear rack slides are provided on two opposite side walls of the groove of the side opening slot unit at the rear of the helmet. The tooth shape of the rear rack slide is inclined forward, and the side opening slot is inserted with an adjustment plate, and the adjustment plate includes a locking tooth segment and a telescopic tooth segment. The locking tooth segment is engaged with the front rack slide, and the telescopic tooth segment is engaged with the rear rack slide. There is a non-tooth segment between the locking tooth segment and the telescopic tooth segment, and the locking tooth segment can only move forward along the side opening slot unit at the front of the helmet. A hand-push anti-slip strip is provided on the top wall of the adjustment plate, and the hand-push anti-slip strip is opposite to the opening of the side opening slot. The telescopic tooth segment of the adjustment plate can only move forward along the rear rack slide, and the tooth pitch of the adjustment plate is 1mm, 2mm or 3.0mm.

[0007] The inclination angle of the front side wall of the teeth of the front rack slide is 60°, the inclination angle of the rear side wall is 50 degrees, and the tooth top width is 2mm. The inclination angle of the front side wall of the teeth of the rear rack slide is 60°, the inclination angle of the rear side wall is 50 degrees, and the tooth top width is 2mm.

[0008] The adjusting piece includes a rear end arc-shaped head, the locking tooth segment, the middle non-tooth segment, the telescopic tooth segment and the rear end non-tooth segment, and the hand-pushing anti-slip strip is arranged on the top wall of the adjusting piece corresponding to the rear end non-tooth segment.

[0009] The front non-toothed area of ​​the rear part of the two opposite side walls of the side opening slot unit at the front of the helmet corresponds to the arc-shaped head at the rear end, and the two opposite side walls of the side opening slot unit at the rear of the helmet are provided with rear rack slideways.

[0010] The thickness of the outer layer is 3-5 mm, and the depth of the side opening groove is 2-2.5 mm.

[0011] The hard material is photosensitive resin, polylactic acid material or polypropylene.

[0012] The soft material is a foam material or foam cotton.

[0013] During the test, a torque pressure-sensitive sensor is installed on the hand-pushed anti-slip strip, and the torque pressure-sensitive sensor is connected to a torque digital display. The comprehensive torque value is set to 2.3 Nm.

[0014] The beneficial effects of the present invention are as follows: First, from the perspective of process design, in order to ensure that the head is always in a bilaterally symmetrical corrective position when designing a helmet, the deformed head is corrected in the direction of a normal head structure through the corrective helmet. The present invention has bilateral openings at the temporal bone, i.e., at the position of the two ears, and is designed to be a structure that can be disassembled front and back, which is convenient for wearing and adjusting. Second, it is different from the structure of previous cranial orthoses, which are adjusted by Velcro or locks on one side of the temporal bone, which belongs to the adjustment method of unilateral opening. The adjustment structure of the present application is a rack movement adjustment, which can achieve precise adjustment of the head circumference. Specifically, the accuracy of each tooth pitch is 1mm, 2mm or 3.0mm. The scaling size of the teeth is determined according to the head size of the infant patient and the growth rate of the infant's head. It is accurate and reliable, and has strong scientificity and safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following examples are merely used to illustrate possible implementations of the present invention, but are not intended to limit the scope of the present invention.

[0024] like Figure 1 and Figure 4As shown, the present invention is an insertable bilaterally adjustable orthopedic helmet system, comprising a split-structured front helmet portion 2 and a rear helmet portion 3, with bilateral openings formed near the ears, and adjustment structures respectively provided between the front and rear helmet portions at the openings above the ears. The orthopedic helmet is divided into an outer layer and an inner lining layer, the outer layer being a hard material such as a photosensitive resin, polylactic acid material or polypropylene, which provides support for the overall structure, and the inner layer being a soft material such as a foam material or foam cotton, to ensure the comfort of the user. The adjustment structure comprises side opening slots on the front and rear helmet portions on both sides of the opening, such as Figure 6 As shown, the side opening groove is in an inverted T-shape, including a groove 20a and a notch 20b. The side opening groove is provided in the outer layer of the orthopedic helmet, the thickness of the outer layer is 3-5mm, and the depth of the side opening groove is 2-2.5mm; a front rack slide 41 is provided at the rear of the two opposite side walls of the groove of the side opening groove unit 4 of the front part 2 of the helmet, and the two side walls of the groove in front of the front rack slide 41 are non-toothed areas. The tooth structure of the front rack slide is the same, which is a unidirectional tooth structure, as shown in FIG. Figure 5 As shown, the tooth shape of the front rack slide is inclined toward the front, the inclination angle a of the front side wall of the tooth is 60 degrees, the inclination angle b of the rear side wall is 50 degrees, and the tooth top width is 2mm. A rear rack slide 51 is provided on the two opposite side walls of the groove of the side opening groove unit 5 of the rear part 3 of the helmet. The tooth structure of the rear rack slide is the same, which is a one-way tooth structure. The tooth shape of the rear rack slide is inclined toward the front, the inclination angle a of the front side wall of the tooth is 60 degrees, the inclination angle b of the rear side wall is 50 degrees, and the tooth top width is 2mm; the rack slide of the side opening groove is inserted with an adjusting piece 1, which is a hard metal or polyurethane, with specific supporting strength. Preferably, the adjusting piece 1 includes a front end arc head 11, the locking tooth segment 12, the middle non Tooth segment 13, the telescopic tooth segment 14 and the rear end non-tooth segment 15; after the locking tooth segment 12 of the adjusting piece is plugged into the front rack slide, the non-tooth area 42 in front of the front rack slide 41 corresponds to the front end arc head 11, and the front end arc head is close to the bottom of the groove, and the telescopic tooth segment 14 is engaged with the rear rack slide 51; the number of teeth of the telescopic tooth segment is 4-6, and the locking tooth segment can only move forward along the side opening groove unit at the front of the helmet, and the top wall of the adjusting piece corresponding to the rear end non-tooth segment 15 is provided with a hand-push anti-slip strip 16, which is facing the groove, and the telescopic tooth segment of the adjusting piece can only move forward along the side opening groove unit at the rear of the helmet, and the tooth pitch of the adjusting piece is 1mm, 2mm or 3.0mm.

[0025] To prevent infants from misoperation, touch the hand-pushing anti-slip strip 16 to test the thrust strength. Figure 7As shown, a torque pressure-sensitive sensor 7 is installed on the hand-pushed anti-slip strip 16, and the torque pressure-sensitive sensor 7 is connected to the torque digital display 8. By changing the tooth thickness structure of the tooth profile, when the inclination angle a of the front side wall of the tooth is 60 degrees, the inclination angle b of the rear side wall is 50 degrees, and the tooth top width is 2 mm, the comprehensive torque value is 2.3 Nm, which realizes that a larger torque is required when the hand-pushed anti-slip strip 16 moves. This torque cannot be moved by improper operation of infants and young children, and is convenient for professionals to adjust.

[0026] The orthopedic helmet can be a porous structure or porous structures of different sizes that conform to seasonal heat dissipation characteristics.

[0027] In summary, the orthopedic helmet of the present application needs to be adjusted in size based on the patient's head circumference growth rate to accommodate the growth of the child's head circumference, typically once a week. Depending on the adjustment requirements, the pitch of the tooth structure can be set to 1mm, 2mm, or 3mm. When adjustment is required, the locking tooth segment on the adjustment plate becomes a fixed structure after meshing with the front rack slide at the front of the helmet and cannot move. Therefore, the head circumference of the helmet is mainly adjusted based on the relative forward movement of the adjustment teeth of the adjustment plate and the rear rack slide. The hand-pushing anti-slip strip is integrated with the adjustment plate S7 to facilitate the sliding of the adjustment plate S7. When the head circumference of the helmet needs to be expanded, the hand-pushing anti-slip strip is pressed and the adjustment plate is pushed in the direction of the arrow. Since the locking tooth segment at the front of the adjustment plate meshes with the front rack slide on the front of the helmet S2 and cannot move, the adjustment plate can only move on the rear rack slide. Due to the unidirectional teeth, it can only move in the direction of the arrow and cannot move backward. According to the head circumference adjustment, the order of magnitude of the tooth pitch movement can be selected through the tooth structure, thereby achieving the expansion and adjustment of the helmet head circumference. In order to avoid the child accidentally touching the hand-pushing anti-slip bar and making mistakes in adjusting the head circumference, we experimented here to obtain the push and press force that can only be adjusted by professional technicians or adults, such as Figure 7 As shown, the torque tester experiment found that when the pressure pushes the hand-pushed anti-slip strip A4, in order to prevent infants from misoperating, the comprehensive torque value is set to 2.3Nm, which improves the safety and reliability of the adjustment piece S7.

[0028] Therefore, in order to achieve accurate head orthosis design, it must conform to the characteristics of infant and young child head growth. This application provides a customized insertable bilaterally adjustable orthotic helmet that can not only design a reasonable head orthosis but also achieve precise size adjustment, making the correction of deformed head more precise.
