[0025] The following is a clear and complete description of the technical solutions of the embodiments of the utility model in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0026] The genioglossus muscle is part of the floor of mouth muscles and is responsible for the tongue protrusion. This technology intends to use electrical stimulation of the genioglossus muscle at the floor of mouth to induce tongue protrusion, expand the oropharyngeal cavity and thus alleviate the occurrence of obstruction events. The advantages over previous technologies are: the stimulation circuit is wrapped in a transparent brace using a "sandwich" lamination technique, and the tongue is induced to protrude by stimulating the floor of mouth muscles. No invasive operations are involved in daily use or maintenance, and patients are easy to accept. By designing an intraoral electrical stimulation treatment system, the occurrence of apnea events can be identified, and electrical stimulation of the floor of mouth muscles can be given in a timely manner to induce tongue protrusion and alleviate oropharyngeal obstruction.

[0027] The utility model provides an intraoral electrical stimulation device for preventing respiratory obstruction, comprising a respiratory sensor and a packaging dental brace.

[0028] Among them, the respiratory sensor is used to collect respiratory signals; the encapsulated braces encapsulate the intraoral electrical stimulation component through the "sandwich technology", and the encapsulated braces include: a first insulating layer 2, a second insulating layer 4 and an electrical stimulation component 3. The structure of the first insulating layer 2 matches the contour of the mandibular dentition model 1, and blind holes are set on both sides of the inner wall of the first insulating layer 2. In one embodiment, blind holes are set on the first insulating layer 2 near the tongue below the tongue. The buccal side is trimmed according to the dentition morphology, and the lingual side is also trimmed according to the dentition morphology, but the range where the blind holes are set is retained; the second insulating layer 4 is sleeved on the first insulating layer 2, and the second insulating layer 4 is tightly fitted with the first insulating layer 2 at the contact position, and there is a accommodating space between the first insulating layer 2 and the second insulating layer 4; the electrical stimulation component 3 is set in the accommodating space, and is connected to the respiratory sensor for communication, and the stimulation electrode of the electrical stimulation component 3 passes through the blind hole and contacts the mucosa in actual use.

[0029] The electrical stimulation component 3 includes a signal processing circuit and a stimulation electrode. Specifically, a signal processing circuit is provided in the accommodation space between the first insulating layer and the second insulating layer, and the above-mentioned intraoral electrical stimulation component is placed at a suitable position of the first insulating layer 2 using an adhesive, and the stimulation electrode passes through the first insulating layer 2 through a blind hole to contact the mucosa. Among them, the signal processing circuit is connected to the respiratory sensor for communication, and the stimulation electrode is electrically connected to the signal processing circuit to generate electrical stimulation to the corresponding part. The influencing parameters of the stimulation electrode (electrical stimulation) include current intensity, pulse width, pulse frequency and duration. The stimulation electrode is a sheet electrode. The electrical stimulation component 3 is a flexible structure, which is attached to the teeth when used and matches the contour of the dentition. In actual use, the respiratory sensor signal is received, and after the respiratory sensor is processed, the sublingual part is electrically stimulated through the stimulation electrode to achieve the forward movement of the tongue and alleviate the obstruction.

[0030] The first insulating layer 2 and the second insulating layer 4 are dental thermoplastic soft films, wherein the melting point of the first insulating layer 2 is 130°C, and the melting point of the second insulating layer 4 is 160°C. Specifically: the first insulating layer 2 is formed by pressing a 1.0 mm dental thermoplastic soft film (melting point 130°C) on a mandibular model by a hot press, forming a shape consistent with the mandibular dentition model. The second insulating layer 4 is formed by pressing a 1.0 mm dental thermoplastic hard film (melting point 160°C) on a mandibular model (the first insulating layer 2 and the intraoral electrical stimulation component bonded to the first insulating layer 2 are relocated on the mandibular dentition model 1) by a hot press. The second insulating layer 4 has a higher melting point than the first insulating layer 2. After cooling, the first insulating layer 2 and the second insulating layer 4 are tightly fitted. The second insulating layer 4 is trimmed according to the range determined by the first insulating layer 2 to encapsulate the intraoral electrical stimulation component 3. Dental thermoplastic soft film is a film made of any one of thermoplastic polyurethane, alcohol-modified polyethylene terephthalate PETG, polyethylene terephthalate, polypropylene, polycarbonate and their mixed components.

The radar respiratory monitoring system transmits a 2.4G frequency band millimeter wave signal through a radio frequency antenna. The target to be measured reflects the electromagnetic wave signal, and the transmitted signal is modulated and processed by a modulator, and then amplified, filtered, ADC and other processes are performed to obtain echo demodulation signal data, and finally the respiratory data is monitored.
