Description

Technical Field

[0001] The utility model relates to the technical field of sputum suction tools, in particular to a sputum suction device for critical care nursing. Background Art

[0002] For critically ill patients, due to their weak autonomous consciousness, when sputum is produced in the trachea, they are unable to expel the sputum by coughing. At this time, when performing nursing operations on critically ill patients, corresponding nursing suction devices are usually used. Traditional manual suction devices rely on nursing staff to press the ball to generate negative pressure, and the patient's vital signs need to be observed simultaneously. One-handed operation can easily lead to unstable suction control, affecting the use effect.

[0003] The utility model patent with the authorization announcement number CN213284754U discloses a critical care clinical nursing sputum suction device, including a piston handle, one end of the piston handle is fixedly connected to a piston shaft, and one end of the piston shaft is fixedly connected to a piston. The critical care clinical nursing sputum suction device, through the matching arrangement of the piston handle, the piston shaft, the piston and the syringe, when in use, the medical staff pulls the piston handle, and then generates suction through the piston shaft, the piston and the syringe, thereby providing suction for the device to suction sputum, through the matching arrangement of the first connecting tube, the knob cover, the knob mouth and the sputum storage bottle, when in use, the medical staff screws the sputum storage bottle into the knob cover through the knob mouth, thereby collecting sputum, and facilitating the disassembly and cleaning of the medical staff, through the matching arrangement of the second connecting tube, the sputum suction head and the sputum suction hose, when in use, the medical staff inserts the sputum suction hose into the patient's throat, and then pulls the piston handle, thereby sucking sputum.

[0004] Although the above technical solution has the effect of facilitating the suction operation of medical staff, most manual sputum suction devices only have the function of suctioning sputum. For critically ill patients, directly inserting the sputum suction tube into the trachea may affect their normal breathing or block the normal supply of external oxygen. In addition, this type of manual sputum suction device cannot provide timely medication treatment to the throat after the suction is completed. Repeated insertion and removal and medication will cause discomfort to the patient, affecting its convenience of use. In view of this, we propose a sputum suction device for critical care.

[0032] Specifically, multiple medicine holes 15 and multiple sputum suction holes 16 are provided on the upper and lower sides of the tube body of the endotracheal tube 1 near the airbag 11, and a medicine tube 151 connected to the multiple medicine holes 15 is fixedly installed on the external end of the endotracheal tube 1, and a drug injection tube 152 is fixedly installed on the end of the drug tube 151, and a second threaded cover 153 is threadedly connected to the drug injection tube 152.
