Detailed Description

The utility model is further described below with reference to the accompanying drawings, the scope of the utility model not being limited to the following:

as shown in fig. 1 to 3, the present application provides a head-mounted mandibular fixator comprising a headgear assembly 1 and a strap assembly 2 connected to each other. The headgear assembly 1 is for fitting over the head of a patient and the strap assembly 2 is for securing the headgear assembly 1. The strap assembly 1 is capable of engaging the mandibular part of a patient to assist the patient in maintaining their mouth closed. The strap assembly 2 includes a first strap 2a and a second strap 2b, each of which is Y-shaped. The first strap 2a is detachably connected to the first side 1a of the headgear assembly 1 and the second strap 2b is detachably connected to the second side 1b of the headgear assembly 1. The first side 1a may be the left side of the headgear assembly 1 and the second side may be the right side of the headgear assembly. The first bandage and the second bandage are Y-shaped, so that the ears of a patient can be avoided when the first bandage and the second bandage are fixed in a binding mode, and further the ears of the patient are prevented from being pressed. The first strap 2a and the second strap 2b each include a first strap body 3, a second strap body 4, and a third strap body 5 that are hinged to each other. For example, a hinge hole is provided at one end of each of the first, second and third bands 3, 4 and 5, and a hinge post is nested in the hinge hole, so that the hinge of the first, second and third bands 3, 4 and 5 can be achieved. Through articulated setting mode for first area body 3, second area body 4 and third area body 5 can rotate relatively, and then when not needing to use, through rotating, make first area body 3, second area body 4 and third area body 5 can pile up together each other, and then reach the purpose that reduces occupation of land space. It will be appreciated that the third strap 5 is provided with a clasp at its end which is sold as disclosed in the prior art and which is used on a schoolbag strap, thereby enabling the connection of the first strap and the second strap. A soft and concave jaw support can be arranged on the third belt body 5 to support the lower jaw of the patient conveniently.

Preferably, the head band assembly 1 comprises a framework 6 which is a circular ring, a plurality of first clamping holes 7 are formed in one end of the framework 6, at least one first clamping block 8 is arranged at the other end of the framework 6, and the first clamping blocks 8 can be arranged in the first clamping holes 7 in a nested mode. When not needing to use, take out back with first joint piece 8 from first joint hole 7, can make the both ends of skeleton 6 separate to make skeleton 6 can expand into the orthoscopic, and then make things convenient for its storage transportation. In addition, after the first clamping blocks are inserted into the different first clamping holes 7, the purpose of adjusting the diameter of the framework 6 can be achieved, so that the framework is suitable for patients with different head diameters.

Preferably, the headband assembly 1 further comprises a support bar 9 in the form of a cross, the support bar 9 comprising a first bar body 9a and a second bar body 9b hinged to each other. For example, the first strip 9a and the second strip 9b are provided with hinge holes at the middle points, and hinge posts are nested in the hinge holes, so that the first strip 9a and the second strip 9b are hinged. When not in use, the first strip 9a and the second strip 9b can rotate relatively to be in a stacked state, so that the purpose of reducing the occupied space can be achieved.

Preferably, the framework 6 is provided with a plurality of second clamping holes 10, and the ends of the first strip 9a and the second strip 9b are respectively provided with a second clamping block 11 which can be nested in the second clamping holes 10. The separation of the headband assembly 1 and the strap assembly 2 can be achieved by taking the second clamping block 11 out of the second clamping hole 10. The detachable split design mode can facilitate the disassembly, assembly and transportation of the head-mounted mandibular fixer.

Preferably, a mesh 12 having a fan shape is provided between the first strip 9a and the second strip 9b. The mesh 12 is not connected to the backbone 6. Can improve the parcel effect to patient's head through setting up the screen cloth. A plurality of second clamping blocks 11 are arranged at the end parts of the first strip body 9a and the second strip body 9b respectively. After the second clamping blocks 11 are inserted into the second clamping holes 10, the tightness degree of the binding band assembly 2 can be adjusted, so that the binding band assembly is convenient for patients with different head types.

The working principle of the application is as follows: the head band assembly 1 is sleeved on the head of a patient, the first binding band bypasses the left cheek of the patient, and after the second binding band bypasses the right cheek of the patient, the first binding band and the second binding band can be connected, so that the lower jaw of the patient can be held, and the mouth of the patient can be kept in a closed state.

Finally, it should be noted that: the foregoing description is only a preferred embodiment of the present utility model, and the present utility model is not limited thereto, but it is to be understood that modifications and equivalents of some of the technical features described in the foregoing embodiments may be made by those skilled in the art, although the present utility model has been described in detail with reference to the foregoing embodiments. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
