Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a head-mounted mandibular tightening device. Background Technique

[0002] Mouth breathing may be caused by various reasons, including nasal diseases (such as chronic rhinitis, turbinate hypertrophy, etc.), tonsil hypertrophy, adenoid hyperplasia, etc. These conditions may lead to poor nasal ventilation, forcing the patient to breathe through the mouth. In addition, some patients may have mouth breathing due to loss of consciousness, tracheal intubation, etc.

[0003] Patients with mouth breathing cannot effectively inhale oxygen, and using a face mask will increase carbon dioxide retention. For this reason, we have designed a head-mounted mandibular tightening device. Content of the Utility Model

[0004] The purpose of the utility model is to provide a head-mounted mandibular tightening device to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A head-mounted mandibular tightening device includes a headband and a mandibular strap. The upper end of the mandibular strap is fixedly connected to both sides of the headband. On the upper side of the curved part at the lower end of the mandibular strap, a fixing plate is fixedly connected. A threaded hole is provided at the center point of the lower part of the fixing plate and the mandibular strap, and a tightening bolt is threadedly connected in the threaded hole. The upper end of the tightening bolt is rotatably connected to a mandibular support through a bearing.

[0007] As a further improvement of the above solution, the mandibular support is circular, and a semi-circular groove is provided on its upper end surface.

[0008] As a further improvement of the above solution, a mandibular pad is provided in the semi-circular groove of the mandibular support.

[0009] As a further improvement of the above solution, the mandibular pad is made of a soft material.

[0010] As a further improvement of the above solution, a handle for driving its rotation is provided at the lower end of the tightening bolt.

[0011] As a further improvement of the above solution, the upper end of the headband extends backward in an arc shape.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The present utility model provides a head-mounted mandibular closing device. The mandibular band is worn on the head through a headgear, and an adjustable mandibular support is provided at the lower end of the mandibular band. The mandibular support is used to upwardly support the mandibular part to help the user close the mouth and keep it closed. The structure is simple, the wearing is convenient, and it can be adapted for use by different people. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solutions of this patent will be further described in detail below in conjunction with the specific embodiments.

[0020] Embodiment, referring to Figures 1 - 4 , a head-mounted mandibular closing device, includes a headgear 1 and a mandibular band 2. The upper end of the mandibular band 2 is fixedly connected to both sides of the headgear 1; on the upper side of the bent part at the lower end of the mandibular band 2, a fixing plate 3 is fixedly connected. A threaded hole is provided at the center point of the lower part of the fixing plate 3 and the mandibular band 2, and a tightening bolt 5 is threadedly connected in the threaded hole. The upper end of the tightening bolt 5 is rotatably connected to a mandibular support 4 through a bearing 6, and a handle for driving its rotation is provided at the lower end of the tightening bolt 5.

[0021] The mandibular support 4 is circular in shape, and a semi-circular groove is provided on its upper end surface. The groove allows the mandibular part to be placed in it. A mandibular pad 7 is provided in the semi-circular groove of the mandibular support 4. The mandibular pad 7 is made of a soft material. In this embodiment, latex is selected to increase the comfort of the mandibular support 4.

[0022] The upper end of the headgear 1 extends rearward in an arc shape to increase the contact area between the headgear 1 and the head, so that the headgear 1 can be worn more stably on the head.

[0023] When in use, put on the headgear 1 on the user's head, place the groove of the mandibular support 4 under the user's mandible, and then turn the handle on the tightening bolt 5, so that the mandibular support 4 moves away from the fixed plate 3, thereby pushing the mandible upward to make the mouth open and close; when the device needs to be removed, it is necessary to turn the handle on the tightening bolt 5 in the reverse direction to loosen the mandibular support 4, and then the mandibular support 4 and the headgear 1 can be removed; the present utility model provides a head-mounted mandibular tightening device, which has a simple structure, is convenient to wear, and can be adapted for use by different people.
