[0002] For patients with artificial airways established, airway clearance is particularly important, especially for patients with viscous sputum. Viscous sputum is prone to adhere to the airway wall. If humidification is not reasonable, the sputum will form crusts, adhere - dry - adhere - dry, and finally block the airway, causing the patient to suffocate. The traditional sputum aspiration method is only effective for sputum, has poor effect on viscous sputum, and is ineffective for sputum crusts. Only fiberoptic bronchoscopy can be used for visible sputum aspiration at the sputum crust site, with high cost, complex operation, and great damage to the airway mucosa.

[0003] The traditional sputum aspiration tube can only aspirate sputum in the trachea. After the bifurcation of the left and right main bronchi, the sputum aspiration tube cannot turn and enter, so deep sputum cannot be aspirated, and only fiberoptic bronchoscopy can be used for cleaning.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0023] Please refer to Figure 1 , a deep suction device provided by the present utility model includes a connector 1, a straight tube 2, and a scraping and suction tube 6 connected in sequence from top to bottom. An arc tube is used for transition between the scraping and suction tube 6 and the straight tube 2. The scraping and suction tube 6 is provided with a suction port 4. An array of barbs 5 is provided on the outer wall of the scraping and suction tube 6. An indicating device 3 is provided on the outer wall of the straight tube 2, and the orientation of the indicating device 3 is the same as the radial direction of the arc tube bend.

[0024] Among them, the center of the connector 1 is penetrated. A conical stepped interface is provided at the upper end of the connector 1 for connecting with a negative pressure device. A control valve 1.2 is provided on the side wall of the connector 1. The control valve 1.2 includes a valve port and a valve cover. The valve port is provided on the side wall of the connector 1. The valve cover is connected to the connector 1 through a flexible connection band. The valve cover can close the valve port. When suction is needed, the valve port is closed and the negative pressure device is started for negative pressure suction. At other times, the valve port is opened to avoid accidental start of the negative pressure device to generate negative pressure.

[0025] Among them, the straight tube 2, the arc tube, and the scraping and suction tube 6 are an integral tube. The straight tube 2, the arc tube, and the scraping and suction tube 6 are flexible tubes. The arc of the arc tube is a self-generated arc during production and will recover after bending. The angle A between the axis of the straight tube 2 and the axis of the scraping and suction tube 6 is 30° - 45°. The bottom of the scraping and suction tube 6 is a round head, which is convenient for the scraping and suction tube 6 to advance in the trachea.

[0026] Preferably, the angle A between the axis of the straight tube 2 and the axis of the scraping and suction tube 6 is 37.5°. This angle is easy for the scraping and suction tube 6 to enter the bronchus through the tracheal branches of most people.

[0027] Among them, the indicating device 3 is a color patch, so that the doctor can know the orientation of the scraping and suction tube 6 during operation.

[0028] Among them, two to four suction ports 4 are provided on the outer wall of the scraping and suction tube 6 and are evenly distributed along the circumferential direction of the scraping and suction tube 6 to improve the suction efficiency.

[0029] Among them, the array of barbs 5 is located below the suction port 4. The array of barbs 5 includes at least two rows and at least two columns of barbs. The angle B between the barb and the axis of the scraping and suction tube is 35° - 45°. The barb is made of a flexible material, such as a medical flexible material like nylon, and will not scratch the bronchus. The lengths of the barbs in the array of barbs 5 gradually become shorter from top to bottom, which is convenient for the scraping and suction tube 6 to advance in the trachea.

[0030] Preferably, the angle B between the barb and the axis of the scraping and suction tube is 40°. This angle is convenient for the scraping and suction tube 6 to advance in the trachea and is also convenient for rotating to remove sputum crusts. Embodiment

[0031] This embodiment provides a method for using a deep sputum suction device, comprising the following steps:

[0032] S1. Open the package and take out a deep sputum suction device under sterile conditions, and fully lubricate the barb array 5 outside the scraping and suction tube 6 with paraffin oil;

[0033] S2. Aim the colored patch to the left side of the patient to ensure that the bend is toward the left, targeting the left mainstem bronchus.

[0034] S3. Quickly lower the tube, ensuring that the colored patch is always facing the left during the lowering process. At this time, the scraper and suction tube 6 will slide down along the airway, and enter the main left bronchus when the airway turns left. After it reaches the bottom, that is, the position where it cannot go down any further, buckle the valve cover of the control valve 1.2, apply negative pressure and rotate it upward until the scraper and suction tube 6 is lifted out of the patient's airway and thrown into the medical waste bin.

[0035] During this period, the sputum is directly sucked away from the sputum suction port 4 by negative pressure, and the sputum crust is hung by the barb array 5 during the rotation and lifting process, a part of which is sucked away, and a part of which is attached to the barb array 5 and lifted out;

[0036] S4. Use the same method to absorb sputum from the right main airway.

[0037] All components and connection methods of components not discussed in this application belong to the known technologies in this technical field and can be directly applied without further explanation.
