Description

Technical Field

[0001] The invention belongs to the technical field of ICU nursing, and specifically refers to a drainage device for postoperative nursing of critically ill patients in ICU. Background Art

[0002] In the intensive care unit (ICU), many patients are unable to effectively drain their body fluids due to their serious condition. Nursing staff need to drain the accumulated fluid or other substances in the patient's body out of the body. If they cannot be discharged in time, it will cause serious health threats to the patient, such as infection, organ dysfunction, and even life-threatening. Therefore, an effective drainage system is crucial for the recovery of ICU patients. Currently, conventional ICU drainage technology mainly relies on negative pressure drainage devices.

[0003] When using a drainage device to drain fluid from a patient's body, the state of the drainage needs to be adjusted accordingly according to the patient's physical condition. However, existing negative pressure drainage devices are generally stable negative pressure suction, which cannot cope with changes in the patient's pathological condition. If the patient's fluid accumulation decreases or negative pressure in the body is increased, if it is not discovered in time, continued external negative pressure suction will cause discomfort to the patient. Excessive negative pressure will cause many hazards to the patient, such as tissue damage, leading to bleeding, pain and other problems. Summary of the invention

The screw rod 40 drives the suction slider 19 to slide downward along the screw rod 40 and the first sliding cavity 23 through the screw hole. The first sliding cavity 23 plays a guiding and limiting role for the suction slider 19. The suction slider 19 drives the first bracket 21 to move downward through the suction connecting plate 28 and the connecting frame 30. The first bracket 21 moves downward along the annular groove 33. When the suction slider 19 moves downward, the gear 36 is driven to rotate through the first rack 37. The gear 36 drives the second rack 38 to move upward. The second rack 38 drives the blocking slider 20 to move upward along the second sliding cavity 24.The blocking slide 20 drives the second bracket 22 to move upward through the blocking connecting plate 29 and the second connecting frame 31, and the second bracket 22 drives the second bracket 34 to drive the blocking rod 14 to move upward, and the blocking rod 14 drives the blocking piston 8 to move upward and block the discharge port 12. When the first bracket 21 is in contact with the bottom wall of the annular groove 33, the blocking piston 8 completes the blocking of the discharge port 12. As the suction slide 19 continues to move downward, the first bracket 21 drives the suction rod 11 to move downward through the bracket 32, and the suction rod 11 drives the suction piston 7 to move downward. The suction piston 7 draws the accumulated fluid in the patient's body into the suction tube 5 through the suction tube 10 and the drainage tube. When the suction piston 7 moves downward to fit the lower positioning ring 74 , the pressure sensor 75 generates an electrical signal under pressure and sends it to the controller 69, the controller 69 controls the motor 39 to stop rotating, and starts the first non-contact liquid level sensor 43 and the second non-contact liquid level sensor 44, the first non-contact liquid level sensor 43 and the second non-contact liquid level sensor 44 detect the liquid level of the suction cylinder 5, when the liquid level in the suction cylinder 5 is between the first non-contact liquid level sensor 43 and the second non-contact liquid level sensor 44, the first non-contact liquid level sensor 43 generates an electrical signal to the controller 69, and the second non-contact liquid level sensor 44 does not generate an electrical signal, at this time, the drainage speed is moderate, and the controller 69 controls the motor 39 to drive The screw rod 40 is reversed and reset, and the screw rod 40 drives the suction piston 7 to move upward through the suction slider 19, pushing the accumulated liquid into the transition tube 6 through the transition tube 9, and the suction slider 19 drives the second rack 38 to move downward through the first rack 37 and the gear 36, and the second rack 38 drives the blocking piston 8 to move downward, so that the drainage pipe port 13 is reconnected with the transition tube 6, and the negative pressure drainage device performs negative pressure drainage again. If the liquid level in the suction tube 5 is lower than the first non-contact liquid level sensor 43, the first non-contact liquid level sensor 43 and the second non-contact liquid level sensor 44 do not generate electrical signals. At this time, the controller 69 controls the high-pressure warning light 71 to light up, and controls the buzzer 72 to sound to warn Medical staff, at this time, the drainage pressure is too high, the medical staff will reduce the negative pressure suction, if the liquid level in the suction cylinder 5 is lower than the first non-contact liquid level sensor 43, the first non-contact liquid level sensor 43 and the second non-contact liquid level sensor 44 will generate electrical signals, at this time the controller 69 controls the high-pressure warning light 71 to light up, and controls the buzzer 72 to sound, to warn the medical staff, at this time, the drainage pressure is too low, the medical staff will increase the negative pressure suction, after the adjustment is completed, press the reset switch, the controller 69 controls the motor 39 to drive the screw 40 to reverse and reset, and according to the current size of the negative pressure suction, adjust the height of the adjustable liquid level monitoring mechanism 76 again to continue monitoring. ,
