Description

Technical Field

[0001] The present invention relates to the technical field of airway support, in particular to an airway support device. Background Art

[0002] When people breathe, air enters and exits the lungs through the bronchi. The bronchi are like branches, divided into small bronchi by large bronchi. At the end of the smallest bronchi, there are air sacs, where oxygen in the air is absorbed by the human body to maintain life, and carbon dioxide is expelled from the body. Tracheal and bronchial stenosis caused by inflammatory granulomas, scars, tuberculosis, trauma, tracheomalacia, amyloidosis, tumors and other lesions can cause obstructive pneumonia, atelectasis and dyspnea. Patients experience symptoms such as dyspnea, wheezing, choking and coughing. In severe cases, respiratory failure may occur and endanger life. Tracheal stent placement is one of the important means to treat airway stenosis, which can quickly relieve dyspnea and improve clinical symptoms. With the successful application of metal stents in angioplasty, they have also begun to be used clinically in recent years for tracheal stenosis, and have achieved satisfactory results. The stents used are stainless steel stents and nickel-titanium memory alloy mesh stents. The stents are woven from the above nickel-titanium memory alloy wires and are used for the main trachea and bronchi.

[0003] When supporting the airway, a connecting pipe is usually extended into the airway, and a protective sleeve is connected to the outer surface of the connecting pipe. The tracheal stent in a compressed state is located between the connecting pipe and the protective sleeve. When the tracheal stent moves to a specified position, the protective sleeve is pulled to move relative to the connecting pipe to expose the tracheal stent, and the tracheal stent expands and recovers to contact the airway to support the airway. However, when the connecting pipe moves to a specified position, the protective sleeve is moved, and the connecting pipe is easily moved, causing the position of the tracheal stent to shift. In order to achieve the purpose of positioning the connecting pipe when installing the tracheal stent, an airway support device is provided. Summary of the invention

[0020] In this embodiment: when installing the tracheal stent 4, the connecting tube 2 is extended into the airway, and the connecting head 1 passes through the narrow position of the airway, so that the tracheal stent 4 is located at the narrow position of the airway. During this process, the first airbag 603 is in an expanded state, and the first airbag 603 pushes the fixing block 605 into the fixing groove 601 through the push plate 604, and the fixing block 605 is engaged in the fixing groove 601, which is convenient for fixing the protective sleeve 3 and the connecting tube 2, and prevents the protective sleeve 3 from moving relative to the connecting tube 2 when the connecting tube 2 is moved, causing the tracheal stent 4 to move out from between the connecting tube 2 and the protective sleeve 3.

[0021] Please refer to Figures 4 to 7 The positioning mechanism 7 includes a cavity 701, the cavity 701 is opened inside the connector 1, the inner wall of the cavity 701 is fixedly connected to a fixing seat 702, an exhaust groove 703 is opened inside the connecting pipe 2, the cavity 701 is connected to the exhaust groove 703, one end of the first airbag 603 is fixedly connected to an air guide tube 704, an oblique tooth groove 706 is opened inside the fixing seat 702, an air guide groove 705 is opened at the top and bottom of the fixing seat 702, and an air outlet 710 is opened on both sides of the fixing seat 702, and the air guide groove 705 and the air outlet 710 are connected to the oblique tooth groove 706 is connected, the positioning mechanism 7 also includes a connecting rope 709, the connecting rope 709 is arranged in the inner cavity of the exhaust groove 703, one end of the connecting rope 709 is located in the inner cavity of the oblique tooth groove 706 and is fixedly connected to a slider 707, the outer wall of the slider 707 is fixedly connected to two deformable conical sheets 708, the conical sheets 708 are fitted with the oblique tooth groove 706, the interior of the connector 1 is located on both sides of the fixed seat 702 to open a connecting cavity 711, the connecting cavity 711 extends to the outer wall of the connector 1, and the inner wall of the connecting cavity 711 is fixedly connected to a second airbag 712.

[0022] In this embodiment, when the tracheal support 4 moves to the specified position, the connecting rope 709 is pulled to move, and the displacement of the connecting rope 709 drives the slider 707 to move, and the displacement of the slider 707 drives the conical sheet 708 to deform and slide in the oblique tooth groove 706.
