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 view of the above problems, the present invention provides a dual-layer laryngeal support device, which is convenient for monitoring the pressure in the support airbag in real time during the operation after the operation, and the spare airbag is arranged to avoid the need of replacing the support device when the support airbag is damaged or the air pressure does not meet the support requirement during the operation.

The technical scheme of the invention is as follows:

a double-layer throat supporting device comprises a supporting air bag and a main air pipe, wherein a standby air bag is arranged inside the supporting air bag, one end of an air outlet of the main air pipe is connected with a first air pipe and a second air pipe through a reversing valve, an air outlet of the first air pipe is connected with an air inlet of the supporting air bag, an air outlet of the second air pipe is connected with an air inlet of the standby air bag, and a first gas pressure sensor and a second gas pressure sensor are respectively arranged on the first air pipe and the second air pipe; when the supporting air bag and the standby air bag are inflated, the whole body of the supporting air bag and the standby air bag is in a triangular prism shape; an air inlet of the main air pipe is provided with an air charging device connecting piece, and a sealing plug is detachably arranged at the air inlet of the air charging device connecting piece.

The working principle of the technical scheme is as follows:

the backup airbag is provided in the support airbag to prevent the support airbag from being deflated or damaged. If a single-layer air bag is adopted, when the single-layer air bag can not provide support in case of air leakage, if the laryngeal mask is taken out in advance, the time for the laryngeal mask to support the local part is not enough, and the function of avoiding local stenosis can not be achieved; if the support device needs to be replaced again in order to ensure the time for providing the support effect, there is secondary damage or the patient may have difficulty in withstanding the replacement process again. The situation can be well avoided by introducing the standby air bag. 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 check that the air pressure in the supporting air bags does not meet the supporting requirement, the supporting air bags are inflated again, at least three minutes are observed, 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 oral sputum suction is needed, the supporting air bag or the standby air bag can be deflated temporarily as necessary according to the situation, so that the sputum can be sucked fully and thoroughly, and the supporting function is continuously provided by inflating after the sputum suction is completed completely; 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, the 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 complete deflation, and the air sac part in the laryngeal cavity can be directly taken out through mouth under the fiber laryngoscope.

In a further technical scheme, the double-layer throat supporting device further comprises an infrared temperature measuring sensor, an induction part of the infrared temperature measuring sensor is provided with an adhesive layer attached to the skin of the neck of a human body, and a display part of the infrared temperature measuring sensor is connected with the main air pipe through a buckle.

The infrared temperature measurement sensor is arranged to facilitate observation of the local temperature of the detected throat and check whether infection exists.

In a further technical scheme, the double-layer throat supporting device further comprises a controller and an alarm, a first signal output end of the controller is connected with a signal input end of the alarm, a first signal input end of the controller is connected with a signal output end of the temperature detection device, a second signal input end of the controller is connected with a signal output end of the first gas pressure sensor, and a third signal input end of the controller is connected with a signal output end of the second gas pressure sensor.

The controller and the alarm are arranged to give an alarm when the temperature or the air pressure changes in the using process conveniently, and family members or medical staff of a user are reminded to look over conveniently.

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;
