End-tidal carbon dioxide-guided airway surface anesthesia tube combined with gastric tube dual-purpose tube

Abstract

The invention relates to an end-expiratory carbon dioxide guided airway surface anesthesia tube combined stomach tube dual-purpose tube which comprises a big catheter. An inner cavity of the big catheter is divided into an end-expiratory carbon dioxide passage cavity and a stomach tube cavity, each of the end-expiratory carbon dioxide passage cavity and the stomach tube cavity is divided into a big tube cavity and a small tube cavity, the small tube cavity in the stomach tube cavity is penetratingly provided with a transnasal approach surface anesthesia tube, the small tube cavity in the end-expiratory carbon dioxide passage cavity is penetratingly provided with a larynx and glottis lower surface anesthesia tube, an end-expiratory carbon dioxide collection port is formed in the side wall of a middle section of the big catheter, the tail end of the larynx and glottis lower surface anesthesia tube extends out from one side, close to the tail end of the big catheter, of the end-expiratory carbon dioxide passage cavity, a gastric content suction port is formed in the side wall of the tail end of the big catheter, and the tail end of the transnasal approach surface anesthesia tube extends out from the tail end of the big catheter. The eend-expiratory carbon dioxide guided airway surface anesthesia tube combined stomach tube dual-purpose tube provides a better condition for awake tracheal intubation and bronchoscopy and can aspirate gastric content of patients who are not prohibited from eating when necessary.

Description

technical field

[0001] The invention relates to the field of medical devices, in particular to an end-tidal carbon dioxide-guided airway surface anesthesia tube combined with a gastric tube dual-purpose tube. Background technique

[0002] Awake tracheal intubation is one of the main measures of the American Society of Anesthesiologists' practical rules for the management of difficult airways. If it is estimated that it may be difficult to ensure effective ventilation and oxygenation after induction of surgical patients, and it is suspected that the patient is at risk of aspiration of gastric contents, the patient should be kept awake for tracheal intubation. As far as awake tracheal intubation is concerned, whether it is fiberoptic bronchoscopic guidance or blind tracheal intubation, the nasal route is easier, because the narrow nasal cavity has a certain support and guiding effect on the FOB or tracheal tube, and the FOB or tracheal tube It is also easier for the catheter ...

Examples

Embodiment Construction

[0017] In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail with reference to the accompanying drawings.

[0018] Such as figure 1 As shown, an end-tidal carbon dioxide-guided airway surface anesthesia tube combined with a gastric tube dual-purpose tube includes a large catheter 100, and the lumen of the large catheter 100 is divided into an end-tidal carbon dioxide channel cavity 110 by a diaphragm at the central axis and gastric lumen 120, the gastric lumen 120 is distributed along the entire length of the large catheter 100, the end-tidal carbon dioxide channel cavity 110 is distributed locally from the head end of the large catheter 100 to the end, the gastric lumen 120 and the respiratory The end-tidal carbon dioxide channel chamber 110 is divided into large lumens 121, 111 and small lumens 122, 112 by the diaphragms near the central axis of the large catheter ...
