9. A use method of a drainage tube for relieving postoperative pain of a thoracic cavity and facilitating fixation comprises the following steps:
the method comprises the following steps: the head end of the drainage tube (1) is sequentially placed into the body of a patient, medical staff hold the locking block (8) on the outer side, so that the inflatable bag (2) connected with the locking block (8) is prevented from moving into the body of the patient, and meanwhile, the medical staff push or pull inwards to adjust the length and the position of the drainage tube (1) entering the body of the patient;
step two: after the position and the length of the drainage tube (1) are determined, the air is inflated into the air delivery tube (13) through the air delivery tube (13) and the second air outlet tube respectively, the air is inflated into the inflatable bag (2) and the supporting bag (53) through the air delivery tube (13) and the second air outlet tube, the supporting bag (53) inflates the chest wall pleura and the lung tissue to reduce severe pain caused by friction between the lung tissue and the pleura during respiration, the inflatable bag (2) inflates inwards and outwards after being inflated, the inflatable bag (2) is gradually extruded to one side of the drainage tube (1) during inflation, so that the drainage tube (1) is clamped and fixed, when the inflatable bag (2) is gradually filled with air to a certain pressure, the entered air enters the third cavity (7) and enters the adjusting air bag (12) through the air outlet hole (11), the adjusting air bag (12) is rapidly inflated and pushes the limiting ring (10) leftwards, and the locking block (8) is extruded to one side of the skin of a patient, when the air pressure in the third cavity (7) reaches a certain value, namely the pressure value of the locking block (8) to the skin is fixed, the air pressure pushes the piston plate (17) outwards, the piston plate (17) drives the first limiting rod (23) to overturn downwards when moving downwards until the first limiting rod (23) is completely separated, the limiting device (21) rotates to the original position under the action of the balancing weight (25), the gliding piston plate (17) drives the connecting rod (18) and the locking rod (46) to extrude the spring (47) downwards, the plug (44) penetrates out of the channel hole (16) under the action of the pressure, the locking rod (46) is clamped between the convex teeth (33) in the fixed wheel (29), the fixed wheel (29) is prevented from rotating, the fixed wheel (29) cannot move relative to the locking block (8) through the clamping teeth (49), and the locking block (8) is prevented from further moving leftwards, at the moment, the inflation is stopped, the piston plate (17) and the connecting rod (18) rise under the action of the spring (47) until the piston plate and the connecting rod are clamped outside the first limiting rod (23) and then stop, at the moment, the upper end of the plug (44) is extruded and sealed outside the channel hole (16), and the locking rod (46) is positioned between the convex teeth (33) of the fixed wheel (29);
step three: after the drainage operation is finished, the drainage tube (1) can be taken out from the body of a patient only by controlling the one-way valve (48) and the second one-way valve (56) to deflate so that the inflatable bag (2) and the supporting bag (53) can recover the original sizes.
