Description

Double-cavity bronchus plugging device convenient for bronchofiberscope guiding intubation

Technical Field

The utility model relates to a medical instrument, in particular to a double-cavity bronchus blocking device convenient for a bronchofiberscope guiding cannula.

In the open chest operation, the patient side lung needs to be temporarily stopped from ventilation, and the healthy side lung needs to be continuously ventilated to facilitate the operation, and in addition, the two lungs need to be ventilated simultaneously before or during the operation. Currently, dual lumen endotracheal tubes or combination bronchial tubes with occluders are used to achieve this.

The existing double-lumen tube or combined tracheal catheter with the plugging device has the following defects: the double-cavity tube is longer and has two plastic bending parts, the intubation is difficult, the requirement on glottis exposure is high, the operation is equivalent to the operation of grasping the rear end of a longer bent tube in the hand of an operator, the front end position of the bent tube is not easy to control, the bronchus end and the main tube have a certain angle in the insertion process, and the airway or the inner wall of the airway is easy to scratch in the process of rotating downwards for insertion; the double-cavity tube also requires the intubation to be aligned at one time, ventilation cannot be realized in the intubation process, and the operation is slow, so that hypoxia of a patient can be caused; the double-cavity tube has stronger stimulation of the band tube because the bronchus end is continuously positioned on one side of the main bronchus, and the tube drawing after transition ventilation after the single tube replacement or laryngeal mask replacement is needed when part of the operation is finished; the current plugging device can only be inserted into a plugging tube under the observation of a bronchoscope in a main trachea, the plugging tube is inserted into a specified direction or position under rotation adjustment depending on the hardness and angle of the plugging tube, but sometimes the condition that the plugging tube is not easy to be inserted into the specified direction or position is quite clear under the bronchoscope, which is probably caused by the interaction of the plugging tube and the bronchoscope in the main trachea, for example, a tank and Pa hose plugging device is hung at the front end of the bronchoscope by a lead wire for guiding the plugging tube, the defect is solved to a certain extent, but the use complexity and the operation steps are increased, and the guiding convenience is obviously inferior to that of the product; when the existing occluder is positioned on one side, the bronchofiberscope can only observe the depth or position of the cuff from the outer side, but cannot observe the depth or position from the inner side, so that the depth and position are inaccurately grasped.

the intubation tube 1. After the outer tube is fully lubricated, the outer tube is inserted into the trachea, and then fixed and connected with a side port for ventilation; 2. the method comprises the steps that after the inner tube (the plugging tube) is fully lubricated, the inner tube is preferentially inserted from the top end to one side in the direction of the side to be plugged (if the direct insertion of the plugging tube into the designated side is difficult, or a bronchoscope is inserted to conduct guiding intubation when the front end of the plugging tube just enters the shunt tube), after the bronchoscope is fully lubricated, the inner tube is continuously inserted into the plugging tube to a proper depth along the bronchoscope after the inner tube enters the designated side (left or right main bronchus), and whether the depth of a sealing tube sleeve is proper or not and whether the front end is unobstructed or not is judged by the bronchoscope; 3. and the bronchoscope is withdrawn, enters the other side from the bronchoscope inlet on the shunt tube, further judges whether the depth and the position of the plugging tube are proper in the main air tube, and further finely adjusts the plugging tube according to the requirement.

Ventilation:

1. ventilation of single lung: the side opening of the shunt tube is connected with a respiratory circuit, the sealing tube sleeve bag is inflated, the sealing tube cap (the second sealing cap and the third sealing cap) is opened to collapse the lung, and the sealing cap (which has elasticity) can be covered with poor effect, so that the aspirator or the injector can be sucked through the small hole to accelerate the collapse of the lung.

2. Double lung ventilation or bulge: the sealing tube sleeve bag is fully deflated, the sealing tube is completely covered until the sealing tube is completely sealed, or the Y-shaped tube is used for ventilating and bulging the lung after the side opening and the inner opening of the sealing tube are connected, or the Y-shaped tube is directly connected with the sealing tube for ventilating and bulging the lung; as with the common occluder, the occluding tube can ventilate the two lungs just after being withdrawn.

Although the occlusion tube can be ventilated, the inner diameter is thin, which is equivalent to the inner diameter of a 3.5-4# common tracheal catheter, and the airway pressure can be high when the tube is used for ventilation alone, so that the operation is not suitable for a long time (the air pressure injury can be caused). Proved by verification, when the outer tube is equivalent to the 37# and 39# double-cavity tube, the plugging tube can be smoothly inserted by adopting the 3.5# and 4.0# spindle-shaped cuff tracheal catheter, one side of the outer tube is inserted into a common adult bronchoscope, the other side of the outer tube is inserted into a plugging tube with a cuff, and the child bronchoscope is inserted into the plugging tube.

Finally, it should be noted that: the foregoing description is only illustrative of the preferred embodiments of the present utility model, and although the present utility model has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements or changes may be made without departing from the spirit and principles of the present utility model.
