Description

Trachea cannula

Technical Field

The invention relates to the field of tracheal intubation, in particular to a tracheal intubation for single lung ventilation.

Background

At present, a plurality of trachea cannula are provided, which has the function that in order to ensure the respiration of a patient, the trachea cannula is inserted into an incised trachea, and the other end of the trachea cannula is communicated with an artificial respirator to realize artificial respiration. The common trachea cannula can only realize single-side air supply by one-time plugging and unplugging, and the intubation process is invisible, so the trachea cannula is difficult to be inserted into one side of a surgical site at one time, and often takes a long time. Because the side of the non-operation position is inserted by mistake, a section is drawn out and then inserted to one side of the operation position. The pain of the patient is increased wastefully by the soaring, and the patient feels afraid. The trachea cannula can realize air supply on two sides alternately, the internal structure is generally that two parallel tubes are controlled respectively, the outer diameter of the trachea cannula is large, a wound needs to be opened greatly, the large-outer-diameter tube easily causes lodging and damage of trachea cilia, and meanwhile, the intubation process is very painful and is not beneficial to the recovery of patients. There is a need to develop a small outer diameter endotracheal tube that facilitates intubation and allows bilateral airway exchange.

The tracheal intubation is 200810163011.6, and is named as a tracheal intubation, wherein the front end of the intubation is provided with a plurality of outer cuffs, the outer cuffs are respectively provided with thin air ducts which are communicated to an injection interface arranged on the outer side of the tracheal intubation, the tracheal intubation is also provided with an inner tube, and one end of the inner tube is provided with an interface end; the outer tube is longer than the inner tube, the outer cuff is arranged on the outer wall of the outer tube, an inner cuff is further arranged on the inner wall of the outer tube away from the spigot end, and an injection port of the inner cuff is arranged at the other end of the outer tube; the inner tube can be drawn in the outer tube, and the drawing stroke is longer than the length of the air holes on the two sides of the outer tube, but shorter than the distance between the two outer cuffs. The inner and outer double pipes are arranged in such a way that when the inner pipe blocks the air holes on the two sides of the outer pipe, air enters the lung lobes on one side through the air outlet at the front end of the outer pipe; if the inner tube is pumped out to expose the air holes on the two sides of the outer tube, an inner sleeve bag is arranged on the inner wall of the outer tube away from the spigot end to inflate and block the air outlet at the front end of the outer tube, and then air is changed into air outlet through the air holes, so that the lung lobes on the two sides can be alternately ventilated. The above operations are realized under the cooperation of the outer cuffs, and the return air can be prevented together. Because the gas is all input from the outer tube, the pain of the patient caused by the large outer diameter can be reduced by controlling the outer diameter of the outer tube. At the same time, the inner diameters of the outer pipe and the inner pipe are properly increased, so that the air supply quantity can be increased.

The scheme adopts the nested structure of the outer pipe and the inner pipe, and switches the working state by inserting and pulling the inner pipe. The ventilation of different lung lobes can be realized without repeated intubation. However, due to the mutually nested structure of the outer tube and the inner tube of the tube, in order to ensure that the inner tube has a sufficient ventilation channel and can be sleeved in the outer tube, the diameter of the tracheal intubation is too large, a wound with a large enough size needs to be cut, and the trachea can be injured.
