Technical Field
The invention relates to the field of medical instruments, in particular to a double-layer throat supporting device.
Background
Treatment of laryngeal cancer is usually based on the size of the tumor range, with surgical resection being preferred. However, it is very important for the long-term life quality of the patient how to maintain the laryngeal function of the patient as much as possible, especially to maintain the size of the laryngeal cavity of the patient to the maximum extent, on the basis of complete removal of the tumor. In current clinical work, depending on the scope of the surgical resection, it may be necessary for the laryngeal tissue remaining after resection to be placed locally with a gauze-filled cuff or silicone tube to provide temporary support. Particularly, when the laryngeal cavity is large in defect and a new laryngeal cavity is formed by local filling of a muscular flap and the like, the thyroid cartilage is partially or completely cut off, so that the partial supporting effect is partially or completely lost, the postoperative airway is seriously collapsed, the tracheotomy tube is difficult to pull out, and the life quality of a patient is seriously affected. Similar devices are also needed for throat stenosis, vocal cord adhesions, uncut larynx, etc. to avoid early restenosis.

In a further technical scheme, an air inlet of the connecting piece of the inflating device is connected with an inflating balloon through threads.
When needing to inflate, take off the sealing plug, will inflate sacculus and aerating device connecting piece and be connected again, conveniently carry out manual inflation to observe the change of its atmospheric pressure through baroceptor.
In a further technical scheme, the outer side of the supporting air bag and the outer side of the standby air bag are both provided with a silica gel coating.
The silica gel coating is arranged on the outer sides of the supporting air bag and the standby air bag, because of good biocompatibility of silica gel, the silica gel coating has no irritation, no toxicity, no anaphylactic reaction and few organism rejection reactions to human tissues; has good physical and chemical properties, can keep the original elasticity and softness in the process of contacting body fluid and tissues, and is not degraded.
The invention has the beneficial effects that:
1. the standby air bag is arranged in the supporting air bag, so that the phenomenon that when the supporting air bag leaks air or is damaged, the laryngeal mask needs to be taken out in advance when the air bag leaks air, the laryngeal mask has insufficient supporting action time on the local part, and the local part is still narrow is avoided; when the air bag is damaged, the supporting device needs to be replaced again in order to ensure the supporting time, but secondary damage exists or the patient can be difficult to endure the replacement again; the air pressure sensors are arranged on the first air pipe and the second air pipe to monitor whether the air pressure in the air bags meets the supporting requirement in real time, if the medical staff checks that the air pressure in the supporting air bags does not meet the supporting requirement, the supporting air bags are inflated again and observed for at least three minutes, if the air pressure in the supporting air bags is not enough after three minutes, the standby air bags are inflated, the supporting air bags are further supported, and the standby air bags are sealed through the sealing plugs after the inflation is finished; if the sputum is required to be sucked through the mouth, the inner air sac can be temporarily deflated according to the situation when necessary, so that the sputum can be fully and thoroughly sucked. If the existing throat model with the silicone tube or the gauze fingerstall is adopted, the shape cannot be changed, and the shape and the volume cannot be changed through air release or other modes, so that a dead angle for sucking phlegm inevitably exists, airway secretion residues are accumulated, and the risk of infection is increased; meanwhile, after the supporting time is enough, when the laryngeal mould needs to be taken out, an invasive taking-out process is not needed, the inner air sac can be completely deflated firstly and then taken out along the path of the laryngeal mould catheter through the tracheotomy opening, if necessary, the catheter wire can be cut off after the inner air sac is thoroughly deflated, and the air sac part in the laryngeal cavity can be directly taken out through mouth under a fiber laryngoscope;
