Technical Field

The invention relates to the technical field of mouth opening trainers, in particular to a mouth opening trainer after nasopharyngeal carcinoma radiotherapy.

Background

The mouth opening difficulty is one of the common sequelae after radical radiotherapy of nasopharyngeal darcinoma, at present, the mouth opening difficulty caused by radiotherapy lacks a better treatment method, once the mouth opening difficulty is difficult to reverse, tools such as a cork, a mouth opener, an empty medicine bottle and the like are usually adopted to assist a patient to support the oral cavity for mouth opening training, but the auxiliary tools such as the cork, the mouth opener, the empty medicine bottle and the like are not flexible enough in training, so that discomfort of the patient is easily caused, and the mouth opening training is not facilitated.

Disclosure of Invention

The invention aims to provide a post-radiotherapy mouth-opening trainer for nasopharyngeal carcinoma, which solves some or some of the defects in the background technology.

In order to achieve the purpose, the invention provides a nasopharyngeal carcinoma radiotherapy post-open training device which comprises a silica gel sleeve, wherein an inner shell is arranged inside the silica gel sleeve, a plurality of springs are annularly arranged in the inner shell at equal intervals, a screw rod is arranged at the center of the upper surface of the inner shell, an air guide channel is arranged on the lower surface of the inner shell, a connecting column is arranged above the inner shell, a reinforcing column is arranged on the connecting column, a threaded hole is formed in the end part, close to the inner shell, of the connecting column, a handle is arranged at one end, far away from the inner shell, of the connecting column, and a through hole is formed.

Preferably, the connecting column is hollow, so that the inner shell is communicated with the interior of the handle, and ventilation and breathing are facilitated during subsequent training.

preferably, the connecting column is in threaded connection with the inner shell, so that the inner shell and the handle can be conveniently mounted or dismounted subsequently.

Preferably, the inner shell has a diameter of 1cm to 4cm, and the inner shells have different sizes so as to be suitable for patients with different diseases.

Preferably, the inner shell tip is equipped with the body angle, prevents inner shell tip edge is sharp-pointed, causes the patient uncomfortable, and the patient damages the silica gel cover.

Preferably, the air guide channel is funnel-shaped, the diameter of the outlet of the air guide channel is increased, and convenience is provided for subsequent breathing of a patient.

Preferably, the spring is fixedly bonded with the inner wall of the inner shell through glue, so that the stability of the spring in the inner shell is ensured, and the inner shell is convenient to reset subsequently.

Compared with the prior art, the invention has the beneficial effects that:

1. This ware is trained to open one's mouth after nasopharyngeal darcinoma radiotherapy, simple structure, convenient operation, safe comfortable patient's passive treatment can cooperate the treatment for a long time, effectively reduces patient's complication, through the inner shell of equidimension not, applicable in the patient of the different state of an illness, reaches the exercise purpose, and the patient can independently operate, improves treatment, has important meaning to the emergence of prevention patient opening one's mouth difficulty, and is with low costs, is fit for wide application.

2. This ware is trained to open one's mouth after nasopharyngeal darcinoma radiotherapy, through the spring of design, can provide the support of power when the training, the guarantee uses elasticity quality for a long time and can satisfy the adjunctie therapy requirement.
