Halo vests and construction methods thereof

Abstract

Halo vests and the construction methods thereof are provided. The halo vests are designed in unibody structures to minimize the number of components. A 3D scanner is utilized to scan a subject to obtain parameters for a modeling program, which help to construct an optimized halo vest for the subject by printing rather than assembling manually. The subject can easily put on the halo vest without miscellaneous steps.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

(7) The examples depicted in the following section are provided for the purpose of detailed explanation of the features of preferred embodiments, in order to enable one having ordinary skill in the art to understand the preferred embodiments.

(8) Referring to FIG. 1 and FIG. 2. FIG. 1 is a diagram illustrating a halo vest, in accordance with the first embodiment of the present invention. FIG. 2 is another diagram illustrating the halo vest, in accordance with the first embodiment of the present invention. The halo vest 1 comprises a halo 10 configured to span a head from one lateral side of the head to another, a supporter 20 in horseshoe-shaped, a vest 30 comprising a frontal region 31 and a posterior region 32, and a strap 40. Each end of the halo 10 comprises a holder 11 having an interior surface as an arc. The interior side at the top of the supporter 20 is configured with a bridge 21, in which the interior surface of the bridge 21 is arc-shaped. The upper part of the vest 30 is connected with the supporter 20, and the lower part of the vest 30 comprises engaging holes 310, 320 at each end of both the frontal region 31 and the posterior region 32. The two ends of the strap 40 are each configured with an engaging element 41 pairing with the engaging holes 310, 320. The holder 11 is connected with the bridge 21 and the bilateral sides of the vest 30 are each linked by a strap 40.

(9) The halo 10 is configured to provide traction force. The halo 10 is arc-shaped in order to fit in the shape of a head. In some other embodiments, the halo 10 is in horseshoe-shaped. The halo 10 and the holder 11 are integrated as a unibody structure. The two ends of the holder 11 are each configured with a thread hole 111. With the thread holes 111, skull pins may be used to secure the halo 10 on the head. The configuration of thread holes 111 avoids obvious wounds on the forehead. The left wing and the right wing of the holder 11 each comprises a first fastener 110, while the left wing and the right wing of the bridge 21, configured at the top of the support 20, each comprises a second fastener 210. The first fasteners 110 and the second fasteners 210 are in alignment, thus bolts can fasten the holder 11 and the bridge 21 through the first fasteners 110 and the second fasteners 210.

(10) In some embodiments, the holder 11 is arc-shaped while the interior surface of the bridge 21 is also arc-shaped. The holder 11 and the bridge 21 therefore could match and fit with each other. In some other embodiments that the holder 11 is arch-shaped, the interior surface of the holder 11 would also be made as an arc to match a head. However, both the exterior surface of the holder 11 and the interior of the surface of the supporter 21 are flat in order to match and fit with each other.

(11) The vest 30 is made in a unibody structure. The frontal region 31 and the posterior region 32 are both U-shaped and corresponding to each other. The engaging elements 41 are preferred to be U-shaped, for the strap 40 to be conveniently attached to the vest 30. However, the engaging elements 41 are not limited to be U-shaped. An engaging element 41 may be H-shaped or in some other shapes as long as the strap 40 could firmly attach to the vest 30. The halo 10, the supporter 20, and the vest 30 may be made of plastic materials. The harden plastic materials help to cage the chest and back of a user to fix the upper part of body and the head in the same position.

(12) The supporter 20 is preferred to be horseshoe-shaped, where the space between two arms is wider than the ear. The supporter 20 is configured on the vest 30. A pair of supporters 20 is preferred to be configured closely to the bilateral sides of the head, and the height of the supporter 20 is determined based on the distance between the shoulder and skull pins. The height of the vest 30 is determined based on the distance between the chest and the shoulder, and the width is determined based on the chest width or the distance between two armpits. The strap 40 is preferred to be configured at a place above the waist and close to the chest.

(13) Some embodiments of the present invention widely applied unibody structures to reduce the number of components of halo vests. The halo 10 is the first unibody structure. The supporter 20 in horseshoe-structure is the second unibody structure. The supporter 20 and the vest 30 together are the third unibody structure. Accordingly, the unibody design reduce risks including loosening of fasteners and dislocating of the components. The halo vests are therefore strong and stable. Another advantage of the unibody design is that the user can apply and secure the halo vest with reduced steps and helps. With the unibody structures, the 3D printing technique can be applied to construct an easy-to-wear and disposable halo vest 1 in a short time.

(14) Referring to FIG. 3 and FIG. 4. FIG. 3 is a diagram illustrating a halo vest, in accordance with the second embodiment of the present invention. FIG. 4 is another diagram illustrating the halo vest, in accordance with the second embodiment of the present invention. The overall configuration is similar to the embodiment in FIG. 1. However, the frontal region 31 and the posterior region 32 are substituted with K-shaped structures. In addition to the U-shaped structure used in FIG. 1 and the K-shaped structure used in FIG. 3, the frontal region 31 and the posterior region 32 may be in H-shape structures.

(15) FIG. 5 is a diagram illustrating a halo vest comprising ribs, in accordance with some embodiments of the present invention. As illustrated in FIG. 5, at least one rib 22 can be installed in the supporter 20 to improve the strength of supporter 20.

(16) FIG. 6 is a flowchart illustrating a construction method of halo vests, in accordance with some embodiments of the present invention. At least one embodiment of the present invention provides construction methods of halo vest. The construction methods comprise a step of establishing a modeling program, a step of scanning a body by a 3D scanner to obtain parameters, a step of performing the modeling program, a step of selecting the design of a halo vest provided in any embodiments, a step of providing the parameters to obtain a 3D image file, and a step of activating a 3D printer for construction based on the 3D image file.

(17) As illustrated in FIG. 6, after the step of establishing the modeling program, a 3D scanner is used to obtain parameters including the head size, shoulder width, chest width, neck width, distance between the widest bilateral line of the head and the shoulder, and curvatures. The parameters are then provided to the model program in the step of providing to obtain a 3D image file mirroring the real object. In the step of activating, a 3D printer constructs a product in accordance with the 3D image file. The product can be applied on a subject and then secure with bolts and skull pins. Under the condition that a user prefers to choose another design from another embodiment, the process may return to the step of selecting in the construction methods. Under the condition that the obtained parameters are invalided, the process may return to the step of scanning in the construction methods.

(18) Accordingly, the 3D printing technique used in the embodiments may construct a customized halo vest for each user or a disposable but comfortable halo vest in 2 hours.

(19) There are many inventions described and illustrated above. The present inventions are neither limited to any single aspect nor embodiment thereof, nor to any combinations and/or permutations of such aspects and/or embodiments. Moreover, each of the aspects of the present inventions, and/or embodiments thereof, may be employed alone or in combination with one or more of the other aspects of the present inventions and/or embodiments thereof. For the sake of brevity, many of those permutations and combinations will not be discussed separately herein.
