Problems solved by technology

However, the device is inserted from the mouth, and its own structure is relatively large, which causes great discomfort to the patient, and the foreign body sensation is heavy, which affects the sleep quality of the patient.
[0004] Publication No. CN107811727A discloses a recyclable heart stent, which uses an elastically stretchable elastic mesh bag, which is implanted in the blood vessel to play a supporting role. Combined with the heating device, it cannot be directly used for airway expansion in application

Embodiment 1

[0031] like figure 1 As shown, this embodiment provides a genioglossus muscle expansion stent for improving the airway of hypoventilation, which is mainly used for sleep apnea syndrome patients during sleep. Usually, during the doctor's diagnosis and treatment, the normal breathing ventilation volume has decreased by 15%. % should be in the severe range. Under normal circumstances, it will be treated by surgical trauma surgery. However, the complications of trauma surgery have certain risks and are not suitable for all patients. However, as an external adjuvant treatment and prevention tool, this expansion stent does not need to be carried out. Surgery is basically suitable for all patients.

[0032] Specifically, as Figure 2-5 As shown, this embodiment includes a sleeve 1, a central tube 2, a bracket body 3 and a number of support arms 4. The sleeve 1 and the central tube 2 are made of medical grade flexible materials, which require good guidance, non-toxic and harmless ,...

Embodiment 2

[0048] like Figure 7-8 As shown, this embodiment provides another genioglossus muscle expansion stent for low ventilation airway improvement. The use method and principle are similar to those in Embodiment 1, except that the stent body 3 in this embodiment is a central angle The arc-shaped structure of not more than 180° can be an elastic mesh structure or a sheet structure.

[0049] The number of the support body 3 is equal to that of the support arm 4. In this embodiment, the number of the support arm 4 and the support body 3 is two. The support arm 4 is connected with the support body 3 in a one-to-one correspondence. The end of the central tube 2 and the other end are connected to the inner wall of the bracket body 3 in a symmetrical form. Both ends of the arc-shaped direction of the bracket body 3 are rounded, so as to avoid sharp corners from damaging the respiratory tract wall.

[0050] Specifically, the stent body 3 is an arc-shaped structure in two separate forms. ...

Abstract

The invention relates to the technical field of medical aids, and relates to a genioglossus muscle expansion stent for improving low-ventilation breathing airways. The expansion stent is applied to the support of the genioglossus, and includes a sleeve, a central tube and a stent body, the center tube penetrates and is sleeved in the sleeve, and the stent body is connected to the end of the sleeve; the sleeve and the stent body are provided with A plurality of support arms, the support arms are of a foldable structure, one end of the support arms is connected with the sleeve and the central pipe, and the other end is connected with the bracket body. When contracted, the support arm is folded, and the support body is folded at the end of the sleeve; when expanded, the support arm is pushed by the sleeve to open, thereby spreading the support body. The present invention is relatively small in size, can enter the human respiratory tract from the oral cavity or from the nasal cavity, flexibly spreads in the respiratory tract, supports the genioglossus muscle at the base of the tongue, prevents the genioglossus muscle from drooping and obstructs the respiratory tract when the patient is lying flat, and effectively relieves hypotension. Compared with surgical treatment, the suffocation phenomenon of patients with ventilation symptoms when lying down and sleeping is basically non-invasive.

Description

technical field [0001] The present invention relates to the technical field of medical aids, and more particularly, to a genioglossus muscle expansion stent for improving the airway of low-ventilation breathing. Background technique [0002] Dyspnea is a common symptom. In the middle of the onset of the new coronavirus, there will be obvious difficulty in breathing, and the breathing often feels hypoxic and cannot breathe normally. It is necessary to use a ventilator or other auxiliary equipment to promote ventilation. In addition, sleep apnea syndrome can also cause breathing difficulties. When sleeping in a supine position, the muscles of the whole body of the patient with sleep apnea syndrome will relax. At this time, the genioglossus muscle at the base of the tongue will sag under the influence of gravity, which will be blocked. Apnea due to respiratory tract, high-risk groups include obesity, narrow respiratory tract structure, muscle relaxation in old age, hyperplasia ...
