Description

Phlegm-sucking low-damage trachea cannula
Technical Field
The utility model relates to the technical field of medical equipment, especially, relate to a low damage trachea cannula of adsorbable phlegm.
Background
The trachea cannula is a device for inserting the trachea of a human body for ventilation in a medical process. The structure is as follows: the periphery of the intubation is sleeved with a closed cuff which is communicated with an air injection pipe. Most of the cuffs applied at present are low-pressure high-volume air bags, and in the using process, in order to prevent the occurrence of air leakage phenomenon, certain air must be injected into the cuffs, so that the airway pressure in the ventilation process is generated, and the effect of closing the airway is achieved. The pressure will undoubtedly act on the tracheal mucosa directly, and if the pressure is small, the air leakage phenomenon is easy to occur. However, if the pressure is too high and the pressing time is too long, the tracheal mucosa has serious consequences of ischemic necrosis.
Based on this consideration, patent 201210212106.9 discloses a double-layer cuff trachea cannula, also called a low-damage trachea cannula, which is characterized in that an opening is formed in the trachea cannula, an inner cuff and an outer cuff are arranged at the opening, a gas injection tube is communicated with a gap between the two cuffs, during the ventilation process, the increase of the airway pressure directly acts on the inner cuff to compress the inner cuff to generate a pressure value equal to the airway pressure, and the pressure can generate the same pressure in the outer cuff to tightly contact with the inner wall of the trachea so as to prevent the occurrence of gas leakage. The pressure source in the inner cuff and the outer cuff completely depends on the airway pressure generated in the ventilation process, so that the inner cuff and the outer cuff automatically keep proper pressure to enable the space between the intubation and the trachea of the human body to be in a closed state without causing the damage of the trachea of the human body. However, in clinical use, due to the establishment of an artificial airway, oropharyngeal secretions cannot be swallowed normally, and accumulate mostly in the oropharyngeal region above the cuff, and such secretions as flow from the cuff rim into the lower airway can lead to the occurrence of VAP.
SUMMERY OF THE UTILITY MODEL
