Description

A multifunctional bronchial occlusion device

technical field

The utility model relates to a multifunctional bronchus blocking device, which belongs to the field of medical instruments.

Background technique

Double-lumen bronchial intubation has become the routine choice for lung separation in thoracic surgery due to its advantages of dividing the two lungs to control ventilation, intraoperative suction, and collapse of the lung on the operative side. Longer, more complications of damage to the trachea, vocal cords, and throat. While the bronchial occluder achieves the same function, it can reduce the incidence of postoperative vocal cord injury, hoarseness and sore throat. Therefore, it is a good method to use a bronchial occluder with an endotracheal tube or a laryngeal mask to construct an artificial airway.

However, there are still many problems with the existing occluder. The gas, blood, and secretions after the blockage are not easy to discharge, which brings inconvenience and difficulty to the operation. During the operation, if the patient turns over, changes in body position, looks up and down, etc., the occluder will be displaced. It is difficult for the single-bag occluder to occlude the lung lobe flexibly and quickly during the operation.

Further, a clamping device is connected to the upper part of the occluder joint, and the clamping device includes three fixing legs, the cross section of each fixing leg is irregular circular, and the thickness of each fixing leg becomes from bottom to top. Thick, there is a gap between the adjacent fixed legs to place the inflatable tube, and there are tight hoops on the three fixed legs. The cross section of the tight hoop includes an inner circle and an outer polygon, preferably a polygon, which is convenient for twisting and tightening The inner diameter of the hoop is larger than the outer diameter of the lower part of the three fixed legs, and smaller than the outer diameter of the upper part of the three fixed legs, so that the tight hoop moves up and down flexibly outside the fixed legs without breaking away. to prevent the hoop ring from slipping off the fixed leg due to excessive force.

Further, the outside of the three fixing legs and the inside of the hoop ring have matching threads, which can be tightened to clamp the internal occluder.

Furthermore, the catheter connector can be connected to a laryngeal mask or an endotracheal tube; preferably the "fourth generation laryngeal mask". After the operation is completed, the laryngeal mask will continue to ventilate after the bronchoscope and occluder are withdrawn, which is less irritating to the patient. When needed, a tracheal tube can also be inserted through the "fourth generation laryngeal mask".

Further, the air supply joint is connected to the breathing circuit, and there is a retractable threaded pipe between the air supply joint and the breathing circuit.

Further, the gas detection joint is equipped with an integrated cap, which can be screwed on or put on the gas detection joint, and the cap can be removed to connect to the gas detection; when the gas detection is not needed, the cap can be covered.

Further, the inflation tube can go inside or outside the wall of the tube body of the occluder.

Further, the sealer includes an upper sealing member and a lower fixing member, the sealing member includes a sealing cover, and elastic sealing sheets arranged obliquely and staggered downwards are fixed in the center of the sealing cover, and the fixing member includes a fixing seat. There are three or four obliquely downward elastic supporting pieces fixed in the center of the fixing seat, the angle between the elastic supporting piece and the vertical direction is larger than the angle between the elastic sealing piece and the vertical direction, and the edge of the sealing piece is integrated with the edge of the fixing piece connection.

The beneficial effects of the utility model are: the utility model is applied in lung surgery, including an occluder, a five-way joint, and a sealer; the suction device can discharge the gas, blood, and secretions of the lungs in time; the ratio of the two airbags An airbag occluder is more flexible and quick to occlude the lung lobes; the five-way connector can be connected to the occluder, fiberoptic bronchoscope, gas detection device, breathing circuit, laryngeal mask or tracheal tube, and has multiple functions. In addition, the clamping device can fix the occluder to prevent the occluder from shifting or even falling out during the operation.
