Abstract

The invention discloses a specific gastric reflux preventing drainage tube for an esophagus drainage type laryngeal mask, and relates to a medical treatment apparatus. The specific gastric reflux preventing drainage tube for the esophagus drainage type laryngeal mask is simple in structure, and can reduce reflux, guarantee isolation between a respiratory tract and digestive tract, and reduce the gaseous distention and aspiration risk. The laryngeal mask comprises a mask body, a ventilating pipe and an esophagus drainage tube; the top opening of the mask body is connected with the ventilating pipe to form a ventilating lane; the esophagus drainage tube is arranged in the ventilating pipe. When the drainage tube is at work, an air tube of the mask body charges air to the mask body; the maskbody is placed in the mouth of a patient, the ventilating pipe above the top part of the mask body is located at a starting part of the esophagus tube; then the tube body of a stomach drainage tube ispenetrated in the esophagus drainage tube located in the ventilating pipe, thus an air sac at the remote end of the pipe body enters a stomach body.

Description

technical field

[0001] The invention relates to a medical appliance, in particular to a special anti-reflux gastric drainage tube for an esophageal drainage type laryngeal mask. Background technique

[0002] As a new type of supraglottic ventilation tool, the laryngeal mask is widely used in clinic due to its advantages of convenient use and small intubation / extubation reaction. Especially in patients with difficult airway and first aid recovery, it is favored by clinicians. However, there are still some limitations in the clinical application of the laryngeal mask. For example, the laryngeal mask ventilation is an end-to-end sealing mechanism. The biggest disadvantage of this ventilation feature is poor sealing. If the airway is completely isolated, serious complications of aspiration are prone to occur.

[0003] With the upgrading of the laryngeal mask, the esophageal drainage type laryngeal mask gradually replaces the ordinary laryngeal mask. Compared with the ordinary...
