[0002] Suctioning refers to a method of sucking out respiratory secretions through the mouth, nose, and artificial airway to keep the airway open and prevent complications such as aspiration pneumonia, atelectasis, and suffocation. It is indicated for comatose patients, patients with a lot of sputum who may suffocate, and patients who need intratracheal medication, contrast agent injection, or sputum dilution. At present, hospitals generally use suction devices to suction patients, but the suction catheter needs to be disinfected after suctioning. The entire suction operation is inconvenient, and the medical staff operates with both hands at the same time, which is also prone to operational errors. At the same time, during the insertion of the catheter, the end of the catheter lacks a structure to fix it except for the medical staff holding it, and because the suction catheter is supported by soft materials, the end of the suction catheter is prone to shaking due to lack of fixation during the suction process, which can easily cause the suction catheter to damage the patient's respiratory mucosa.

[0039] Specifically, the driving assembly 31 includes an adjusting disk 311 and a double-sided rack 312 disposed in the middle of the adjusting disk 311 .

[0040] More specifically, a sliding groove is provided at the transverse midline of the adjusting disk 311 , and the double-sided rack 312 is slidably connected to the adjusting disk 311 via the sliding groove.

[0042] The specific process is that the double-sided rack 312 moves rightward to drive the upper missing gear 323 engaged with it to rotate, and the rotation of the upper missing gear 323 drives the upper connecting rod 324 to deviate to the lower left, so that the connecting shaft 322 set on the upper sleeve 321 can cooperate and move in the movable groove 325 opened on the upper connecting rod 324.

[0044] Specifically, the double-sided rack 312 moves rightward to drive the meshing lower gear 328 to rotate, and the rotation of the lower gear 328 drives the lower connecting rod 327 to shift to the upper left, thereby driving the lower sleeve 326 to shift to the upper left, so that the connecting tube 5 sleeved in the lower sleeve 326 is folded to the upper left to form a closed state.

[0045] Furthermore, the limiting mechanism 6 includes a sleeve 61 sleeved on the outside of the connecting pipe 5, and limiting rods 62 passing through the sleeve 61 are arranged on opposite sides of the sleeve 61, and a limiting plate 63 is connected to the limiting rod 62, and a spring 64 is sleeved on the limiting rod 62 between the limiting plate 63 and the sleeve 61.

[0046] In detail, the stopper 63 is an arc-shaped structure, one end of the spring 64 is fixedly connected to the stopper 63, and the other end abuts against the inner wall of the sleeve 61.

[0050] Specifically, by setting the telescopic ruler 71, the length of the displacement of the remaining connecting tube 5 when the connecting tube 5 is folded and closed can be accurately measured, thereby avoiding the inconvenience caused by repeated debugging during later use. In addition, by setting the telescopic rod 72 and the guide rod 73, the technical effect of guidance during the linkage process can be achieved.

[0051] Specific application cases: Suctioning refers to a method of sucking out respiratory secretions through the mouth, nose, or artificial airway (tracheotomy) to keep the airway open and prevent complications such as aspiration pneumonia, atelectasis, and suffocation. It is indicated for comatose patients, patients with a lot of sputum who may suffocate, and patients who need intratracheal medication, contrast agent injection, or sputum dilution.

[0052] The process of suctioning mainly consists of the following steps: Operator preparation includes washing hands, wearing a mask, and preparing the instruments needed for suction.

[0053] The operator assesses the patient's condition and whether he or she is suffering from hypoxia, and checks the patient's information. If the patient is awake, the purpose of the operation should be explained to him or her to obtain his or her cooperation. If the patient is unconscious, a tongue depressor or mouth opener should be used to help him or her open his or her mouth.

[0054] Carry out good monitoring, including blood oxygen saturation, pulse, blood pressure, heart rate and respiratory sounds.

[0055] To perform suction operation, turn on the suction switch, wear gloves, connect the suction device, and try to suck saline to test whether the tube is unobstructed. Then insert the suction tube into the patient's nasal cavity or oral cavity to suck out the secretions. Replace the suction tube, fold the end of the tube, insert it into the trachea to an appropriate depth, then release the end of the tube, rotate it left and right to lift the suction tube to suck out the sputum. After suctioning, turn off the suction device, remove the suction tube, and observe the patient's condition.

[0056] The specific operation of applying the suction connecting tube fixing device of the present application to the suction technique is: through a fixing rod 21 set on the bracket 1, and a plurality of fixing blocks 22 are set on the fixing rod 21, and a clamping notch is opened on the fixing block 22, and the technical effect of clamping and fixing the suction catheter 4 is achieved through the plurality of clamping notches, so that the suction catheter 4 is placed stably and neatly.

[0057] Furthermore, the connection between the sputum suction catheter 4 and the connecting tube 5 is achieved by providing a card slot on the outer wall of the sputum suction catheter 4 and a card block on the inner wall of the connecting tube 5 .

[0058] Furthermore, during the intubation process, the double-sided rack 312 moves rightward to drive the upper missing gear 323 and the lower missing gear 328 that are meshed with it to rotate. The rotation of the upper missing gear 323 drives the upper connecting rod 324 to deviate to the lower left, so that the connecting shaft 322 provided on the upper sleeve 321 can cooperate in the movable groove 325 provided on the upper connecting rod 324; the rotation of the lower missing gear 328 drives the lower connecting rod 327 to deviate to the upper left, and then drives the lower sleeve 326 to deviate to the upper left, thereby achieving the technical effect of folding the connecting tube 5 sleeved in the lower sleeve 326 to the upper left to form a closed state, thereby avoiding the technical problem of respiratory mucosal damage caused by the negative pressure generated during the intubation process.

[0059] Furthermore, before the connecting tube 5 is folded, there is a surplus of the connecting tube 5 between the folding mechanism 3 and the limiting mechanism 6. By arranging a sleeve 61 outside the connecting tube 5, the connecting tube 5 is clamped and fixed by the limiting rods 62 arranged through the opposite sides of the sleeve 61 and the arc-shaped limiting pieces 63 connected to the limiting rods 62. The clamping and restriction of the connecting tube 5 is further realized by the elastic force of the spring 64 arranged on the limiting rod 62 between the limiting piece 63 and the inner wall of the sleeve 61, thereby achieving the technical effect of stabilizing the connecting tube 5 and avoiding the technical problem of damage to the respiratory mucosa caused by the movement of the connecting tube 5 during intubation or suctioning.

[0060] During the folding and closing process of the connecting tube 5, a telescopic ruler 71 is connected between the sleeve 61 and the lower sleeve 326, and a telescopic rod 72 is rotatably connected to the telescopic ruler 71, and a guide rod 73 is connected to the telescopic rod 72, and the guide rod 73 is connected to the double-sided rack 312. The setting of the telescopic ruler 71 can accurately measure the displacement length of the remaining connecting tube 5 when the connecting tube 5 is folded and closed, avoiding the inconvenience caused by repeated debugging during later use, and the setting of the telescopic rod 72 and the guide rod 73 can achieve the technical effect of guidance during the linkage process.

[0061] After the intubation is completed, the double-sided rack 312 moves to the left, driving the upper missing gear 323 and the lower missing gear 328 meshing with it to rotate, and the rotation of the upper missing gear 323 drives the upper connecting rod 324 to deviate to the upper right, so that the connecting shaft 322 set on the upper sleeve 321 can move in the movable groove 325 opened on the upper connecting rod 324; the rotation of the lower missing gear 328 drives the lower connecting rod 327 to deviate to the lower right, and then drives the lower sleeve 326 to deviate to the lower right, realizing the process of resetting the connecting tube 5 sleeved in the lower sleeve 326 to the lower right and circulating it, and the suction operation is performed after the connecting tube 5 is circulated.

[0062] After the sputum suction is completed, the connecting tube 5 can be removed for disposal.

[0063] It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The protection scope required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
