Description

Technical Field

[0001] The utility model relates to the field of medical technology, and more specifically, to a visual sputum suction throat tube. Background Art

[0002] It is known that the larynx is a passage for breathing, phonation, and swallowing food. It is connected to the pharyngeal cavity above and the esophagus leading to the stomach and the trachea leading to the lungs below. The larynx is behind the pharynx; the front is covered by the infrahyoid muscles; the sides are the blood vessels and nerves of the neck and the lateral lobe of the thyroid gland. The larynx is supported by cartilage, which is connected by joints and ligaments; there are muscles attached to make the joints move, and the inner surface of the larynx is lined with mucosa to form the laryngeal cavity; and the cartilage of the larynx mainly includes unpaired thyroid cartilage, cricoid cartilage, epiglottic cartilage, and paired arytenoid cartilage; in clinical treatment in hospitals, some patients will secrete a large amount of sputum in their trachea, which is difficult for the patients to discharge by themselves, and then medical staff need to perform sputum suction operations to keep the patients' airways open and prevent complications such as aspiration pneumonia, atelectasis, and suffocation caused by sputum blockage; and the existing sputum suction method is: medical staff use their own clinical experience to insert a sputum suction tube into the patient's trachea for sputum suction operations.

[0003] However, in actual use, since the epiglottis cartilage in the throat leading to the trachea of ​​the patient blocks the trachea, the suction tube can be inserted into the trachea only when the patient starts to breathe and opens the epiglottis cartilage. Therefore, the existing operation not only requires the nursing staff to have clinical experience, but also there are cases where the suction tube fails to be inserted into the trachea multiple times, and the patient's comfort is low. Therefore, a visual suction tube is proposed as a further improvement. Utility Model Content

[0024] A tooth pad device 2 is installed on the side wall of the laryngeal tube body 1; the end face of the laryngeal tube body 1 inserted into the patient's throat is set as an inclined surface a, and the shape of the laryngeal tube body 1 close to the inclined surface a is set to an arc shape, a camera 3 with a light source is fixedly installed at one end of the light source channel 12 close to the inclined surface a, and a visual device 4 is set on the front of the tooth pad device 2.

[0025] Among them, the laryngeal tube body 1 is inserted from the oral cavity into the laryngeal cavity, and the epiglottis cartilage is lifted by using the inclined surface a at the end of the laryngeal tube body 1, and then the arc shape at one end of the laryngeal tube body 1 is used, and then when the laryngeal tube body 1 is rotated 180°, it is more convenient to insert into the trachea, and then the suction tube can use the suction tube channel 13 opened in the laryngeal tube body 1 to directly enter the patient's airway for suction operation.

[0026] The oxygen supply channel 11 is used to connect to the oxygen supply hose; when the laryngeal tube body 1 is inserted into the trachea, the oxygen supply hose connects to the oxygen supply channel 11, so that oxygen can enter the patient's airway through the oxygen supply channel 11, thereby preventing the medical staff from affecting the patient's breathing when performing sputum suction.

[0027] Among them, the light source channel 12 is used to place a camera 3 with a light source; so that when medical staff operate the laryngeal tube body 1, they can use the camera 3 with a light source to provide necessary light source and field of view in the patient's mouth, thereby making it easier to lift the epiglottis cartilage and insert the trachea, thereby improving the efficiency of the suction operation, reducing unnecessary touching of the patient's throat, and thus improving comfort.

[0028] In a preferred embodiment, as shown in the attached Figure 1 , Attachment Figure 2 and attached Figure 3 As shown, U-shaped slots 21 are formed on both sides of the bite block device 2 , and the side surfaces of the throat body 1 are snap-connected to the U-shaped slots 21 of the bite block device 2 .

[0029] Among them, the tooth pad device 2 is used to support the patient when the patient's mouth is closed, so that the laryngeal tube body 1 is not affected by the closure of the patient's mouth, avoiding the laryngeal tube body 1 from being flattened by the teeth, and preventing the closure of the mouth from affecting the insertion of the suction tube; the U-shaped card slot 21 is used to fix the laryngeal tube body 1 that has been operated, so as to facilitate medical staff to independently perform subsequent insertion of the suction tube operation.

[0030] In a preferred embodiment, as shown in the attached Figure 1 , Attachment Figure 2 and attached Figure 3 As shown, the visual device is configured as a display screen connected to the camera 3 signal; so that the display screen can display the image captured by the camera 3 in real time, thereby facilitating the operation of the throat tube body 1 by medical personnel;

[0032] In a preferred embodiment, as shown in the attached Figure 1 , Attachment Figure 2 and attached Figure 3 As shown, the materials of the throat tube body 1 and the tooth pad device 2 are both set to silicone material; so as to utilize the elasticity and flexibility of silicone to protect the patient and avoid scratches on the inner wall of the patient's oral cavity.

[0033] In a preferred embodiment, as shown in the attached Figure 1 , Attachment Figure 2 and attached Figure 3 As shown, the length of the throat body 1 is set to at least 24 cm;

[0034] Among them, taking into account the clinical situation: the distance from the child's mouth to the glottis is 7.5cm-16cm, so in order to ensure the operation of the laryngeal tube body 1, at least 6cm is required as a handle for grasping and controlling. Therefore, based on the above considerations, the length of the laryngeal tube body 1 is set to at least 24cm.

[0035] In a preferred embodiment, as shown in the attached Figure 1 , Attachment Figure 2 and attached Figure 3 As shown, the outer diameter of the throat tube body 1 is set to be at least 20 mm, so that the oxygen supply channel 11, the light source channel 12 and the sputum suction tube channel 13 provided in the throat tube body 1 can play corresponding roles;

[0036] Among them, the outer diameter of the existing suction tube ranges from 2mm to 6mm; the outer diameter of the commonly used oxygen supply hose is 12.4mm; therefore, considering the need to ensure smooth movement of the suction tube and docking with the oxygen supply hose, the outer diameter of the throat tube body 1 is set to at least 20mm, and the excess part can be used for the light source channel 12 to install the camera 3.

[0037] Working principle of the utility model: when in use, the medical staff first places the tooth pad device 2 on the patient's tooth occlusion for support, then operates the laryngeal tube body 1 to be inserted from the oral cavity to the laryngeal cavity, uses the camera 3 with a light source to provide the necessary light source and field of view in the patient's oral cavity, then operates the inclined surface a at the end of the laryngeal tube body 1 to lift the epiglottis cartilage, rotates the laryngeal tube body 1180 degrees and then inserts it into the trachea; then fixes the laryngeal tube body 1 in the U-shaped card slot 21 opened by the tooth pad device 2 for fixation; finally, docks the oxygen supply channel 11 with the oxygen supply hose, and inserts the sputum suction tube into the airway along the sputum suction tube channel 13 to perform sputum suction operation;

[0038] When the sputum suction is finished, the sputum suction tube is first taken out, then the throat tube body 1 is taken out, and finally the tooth pad device 2 is taken out.
