Problems solved by technology

However, the main purpose of this device with a drainage tube communicating with the opening of the esophagus is to avoid leaking of any gastric fluids produced by the esophagus from the sides of the device, since these fluids would consequently pose a great risk to the patient, which Such a leak would risk contamination of the throat, so placing the device in this way is not satisfactory
[0012] Furthermore, existing devices with gastric drains do not have a tube with a diameter equal to that of the esophageal sphincter, thus only increasing the velocity of fluid flow into the drain, which, as described above, results in a decrease in pressure in the narrow tube. Small, causing fluid outflow from the high-pressure area to force the distal end of the device away from the sphincter

Embodiment Construction

[0060] Where the following illustrative embodiments are described, like reference numerals are generally used herein to refer to similar structures.

[0061] Referring to the accompanying drawings, there is shown an artificial airway device 1 for assisting lung ventilation of a patient. The device 1 includes an airway tube body 2, a gastric discharge tube body 3 and a cover at one end of the airway tube body 2 The shell 4 includes a back plate 5 and has a peripheral forming body 6 capable of forming a seal around the periphery of the throat inlet, the peripheral forming body 6 encircling the hollow interior space or lumen 7 of the shell 4, at least An airway tube body 2 is opened in the inner cavity of the mask, wherein the mask body includes an opening 8 , and the opening hole 8 is used to pass the gastric material leaving the esophagus to the gastric discharge tube 3 .

[0062] For convenience, in this paper, as figure 1 The surface of the device shown is called the back s...

Abstract

The invention relates to an artificial airway device (1) to facilitate lung ventilation of a patient, comprising an airway tube (2), a gastric drain tube (3) and a mask (4) at one end of the airway tube (2), the mask (4) including a backplate (5) and having a peripheral formation (6) capable of forming a seal around the circumference of the laryngeal inlet, the peripheral formation (6) surrounding a hollow interior space (7) or lumen of the mask (4) and the airway tube (2) opening into the lumen of the mask, wherein the mask includes an atrium (8) for passage to the gastric drain tube (3) of gastric matter leaving the oesophagus.

Description

technical field [0001] The present invention relates to an artificial airway device, in particular a device intended to prevent gastric reflux. Background technique [0002] For as long as 70 years, an endotracheal tube comprising an elongated catheter with an inflatable balloon placed near the distal end has been used to establish the airway in comatose patients. In operation, the distal end of the endotracheal tube is inserted into the patient's trachea via the patient's mouth. Once the endotracheal tube is positioned, the balloon is inflated, forming a seal with the lining of the trachea. After this seal is formed, positive pressure can be applied to the proximal end of the catheter to open air to the patient's lungs. In addition, the seal between the balloon and the lining of the trachea prevents lung aspiration (for example, a seal prevents material regurgitated from the stomach from being drawn into the patient's lungs). [0003] Despite the effectiveness of such en...
