Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a bronchial blocking catheter capable of preventing displacement and blockage. Background Art

[0002] Bronchial blocking catheters are medical devices primarily designed for insertion and placement within the bronchi. Their primary function is to block areas of bleeding or excessive secretions in the bronchi, thereby preventing the flow of blood or secretions to the lungs and potentially serious respiratory problems. Bronchial blocking catheters are typically made of flexible materials and can be inserted into the patient through procedures such as bronchial intubation or tracheotomy. They are widely used in the treatment and prevention of respiratory diseases.

[0003] Currently, catheters mainly use a soft balloon at the end. By injecting gas into the balloon, it fits tightly against the inner wall of the bronchus to block bleeding or secretions in the bronchus. During use, existing catheters can easily shift as the patient breathes or moves, causing blockage and affecting the patient's breathing. In addition, when the catheter shakes, it will rub against the protuberance of the trachea, causing discomfort to the patient. Moreover, bleeding or secretions in the bronchus on the diseased side can easily enter the bronchus on the healthy side, affecting the ventilation of the lungs on the healthy side. Utility Model Content

Therefore, they cannot be understood as limitations on the present invention.

[0024] Example:

[0025] Reference Figures 1-4 A bronchial blocking catheter that can prevent displacement and blockage includes a main catheter 1, which can be made of medical rubber, plastic, silicone, polytetrafluoroethylene and other materials. It also includes: a blocking unit arranged on the main catheter 1, used to block the patient's main trachea and one of the bronchi; an anti-bite piece 7 arranged on the main catheter 1, used to reduce the deformation of the main catheter 1 when the patient bites; and an adjustment unit arranged on the main catheter 1 and the blocking unit, used to adjust the breathing mode of the other bronchus.

[0026] Reference Figure 1 The blocking unit includes a main tracheal cuff 3 and a first bronchial cuff 4 connected to the main catheter 1. The main catheter 1 is provided with a first inflation tube 5 connected to the main tracheal cuff 3 and a second inflation tube 6 connected to the first bronchial cuff 4, wherein the first bronchial cuff 4 is located at the end of the outer wall of the main catheter 1.

[0027] The connection method between the main tracheal cuff 3 and the first bronchial cuff 4 and the first inflation tube 5 and the second inflation tube 6, as well as the second bronchial cuff 9 and the third inflation tube 10 can refer to the technical solutions in the prior art. Those skilled in the art will know it and will not be described in detail here. It needs to be explained that when the main tracheal cuff 3, the first bronchial cuff 4 and the second bronchial cuff 9 are inflated, their volume will increase until they are tightly fitted with the inner wall of the patient's main trachea or bronchus, thereby achieving a blocking effect.

[0028] Reference Figure 1 and Figure 4 The anti-bite part 7 includes an outer soft body 71 and an inner hard body 72. The outer soft body 71 and the inner hard body 72 are both connected to the outer wall of the main conduit 1. The outer soft body 71 and the inner hard body 72 are connected, wherein the inner wall of the inner hard body 72 fits with the outer wall of the main conduit 1, and the outer wall of the outer soft body 71 is concave.

[0029] Among them, the outer soft body 71 can be made of materials such as rubber or silicone to increase the comfort of the patient's teeth, and the inner hard body 72 can be made of hard plastic material to reduce the pressure on the main catheter 1 when the patient bites, which can prevent the main catheter 1 from leaking and ensure the stability of the patient's lung breathing.

[0030] Reference Figure 1 and Figure 3The adjustment unit includes a bronchial catheter 8 arranged between the main catheter 1 and the main tracheal cuff 3, the bronchial catheter 8 is connected to the second bronchial cuff 9, and also includes a third inflation tube 10 connected to the main catheter 1, the third inflation tube 10 is connected to the second bronchial cuff 9 through the main catheter 1, the main tracheal cuff 3 is provided with a tube hole 11 matching the second bronchial cuff 9, the main tracheal cuff 3 is provided with a ventilation groove 12 on the side close to the main catheter 1, and a connecting hole 13 connected to the ventilation groove 12 is provided on the side wall of the main catheter 1, and a support member 14 is provided between the ventilation groove 12 and the main tracheal cuff 3, wherein the bronchial catheter 8 passes through the outside to the inside of the main catheter 1, and passes through the main tracheal cuff 3 to the outside of the main catheter 1, and the bronchial catheter 8 passes through the ventilation groove 12.

[0031] It should be explained that the connection position between the bronchial tube 8 and the main tube 1 is in a sealed state, and there is a certain friction between the bronchial tube 8 and the tube hole 11, which can reduce the displacement of the bronchial tube 8 during use. In addition, when the interior of the main tracheal cuff 3 is inflated with gas, the pressure between the tube hole 11 and the bronchial tube 8 increases, which can fix the bronchial tube 8. Moreover, the main tracheal cuff 3 is not connected to the ventilation groove 12 and the tube hole 11, and the size of the ventilation groove 12 is also larger than the size of the bronchial tube 8; when the end of the bronchial tube 8 is located in the ventilation groove 12, after the main tracheal cuff 3 is inflated with gas, the tube hole 11 in the upper part is in a sealed state, and the force generated by breathing is difficult to open the tube hole 11.

[0032] Reference Figure 1-Figure 2 The end of the main catheter 1 away from the first bronchial cuff 4 is connected to the ventilation interface 2, and the ends of the first inflation tube 5, the second inflation tube 6 and the third inflation tube 10 away from the main catheter 1 are connected to the inflation connector 15.

[0033] The end of the ventilation interface 2 is connected to an external ventilator, and the inflation connector 15 can be connected to the inflation device. This is a conventional method in the prior art and will not be described in detail.

[0034] In the present invention, when intubating the patient's affected bronchus, with the assistance of a laryngoscope, the end of the main bronchial tube 1 is inserted into the bronchus on the affected side of the patient, and the bronchial tube 8 is inserted into the bronchus on the healthy side of the patient. The main bronchial cuff 3, the first bronchial cuff 4, and the second bronchial cuff 9 are inflated through the inflation connector 15 so that they are tightly fitted with the patient's main bronchus and the inner walls of the bronchi on both sides, respectively. The ventilation interface 2 is connected to the ventilator. At this time, the first bronchial cuff 4 can block the bronchus on the affected side to prevent bleeding or secretions from entering the lungs.

[0035] If the other bronchus of the patient is healthy, the end of the bronchial tube 8 is extended to the outside of the main bronchial cuff 3. At this time, the patient's healthy bronchus can breathe through the bronchial tube 8. Under the action of the second bronchial cuff 9, bleeding or secretions can be prevented from entering the healthy bronchus, ensuring ventilation of the healthy lung. It can also fix the main bronchial tube 1 and prevent it from rubbing against the carina during the patient's breathing, thereby improving the patient's comfort.

[0036] If both bronchi of the patient need to be intubated, the end of the bronchial tube 8 is placed in the ventilation groove 12. At this time, the bronchial tube 8 is connected to the main tube 1, and breathing can be achieved in both lungs of the patient through the ventilator.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
