Description

an endotracheal tube

technical field

The utility model belongs to the field of medical instruments, in particular to a tracheal intubation tube.

Background technique

Endotracheal intubation is a commonly used rescue technique in emergency work, and it is the most widely used, most effective and fastest means in airway management. With the continuous advancement of medical technology, endotracheal intubation and ventilator treatment are becoming more and more common. However, during the use of the ventilator, accidental detachment of the tube will cause great harm to the patient and affect the patient's recovery.

With the development of endotracheal intubation nursing technology, through the efforts of medical staff, the rate of accidental endotracheal intubation has dropped significantly.

Clinically, the medical staff generally fix the endotracheal tube and the hard dental pad together. In this process, double fixation with adhesive plaster and tape is required to prevent displacement or prolapse. The workload of the medical staff is heavy, and the actual operation is not easy. It is convenient, and sometimes it is difficult to achieve a good fixing effect; in addition, when it is necessary to adjust the insertion depth of the endotracheal tube in the trachea, the original adhesive tape must be removed, and after the insertion depth is adjusted, it is fixed again with adhesive tape, which increases the The workload of medical staff.

In addition, in order to improve the safety and convenience of the endotracheal intubation process, some people set a movable pressure block on the fixed tube of the wing plate. The position of the tracheal intubation can be fixed by the pressure block on the endotracheal tube, thereby fixing the endotracheal intubation in the fixed tube. However, the fixation achieved by this method is not stable, and the endotracheal tube is in surface-to-face contact with the fixing tube and the pressing block. As long as the screw is slightly loose, the endotracheal tube is still prone to slipping, threatening the health of the patient.

Utility model content

The purpose of this utility model is to provide a tracheal intubation that is easy to use, strong in stability, and can adjust the insertion depth in view of the deficiencies in the prior art. The tracheal intubation can greatly reduce the workload of medical staff, improve nursing efficiency, and greatly Reduced risk of detachment.

The technical scheme of the utility model is: a tracheal intubation tube, including a tube body and a wing plate, the wing plate is provided with a fixed tube, the fixed tube is sleeved outside the tube body, the tube body includes a thickened section, the The thickening section is provided with a plurality of grooves; the fixed tube is provided with a locking device and a through hole, and the locking device includes a pressing plate, and the pressing plate is hinged on the fixing tube at the through hole through a hinge shaft. The inner side of the right end of the pressing plate is provided with a locking block that can be engaged with the groove, and the left end of the pressing plate is connected to the outer wall of the fixing pipe through an elastic element.

With such a structural design, the tube body is clamped in the fixed tube through the locking block on the locking device, so that the tube body cannot move left and right relative to the fixing device, preventing the tube body from moving relative to the fixed tube when it falls off the ventilator. As a result, the insertion depth changes; when it is necessary to adjust the depth of the tube body in the patient's trachea, you only need to press the pressure plate, so that the pressure plate rotates around the hinge axis, the elastic element is tightened, the pressure plate rotates outward, the locking block is separated from the groove, and then Adjust the insertion depth of the pipe body. After the adjustment, release the pressure plate. Under the action of the elastic element, the locking block will automatically engage with the groove to fix the pipe body in the fixed pipe.

Furthermore, the groove (12) is an annular groove, which facilitates the engagement of the tube body and the fixing device, and improves the ease of use of the tracheal intubation tube.

Further, the number of said through holes is 2, said 2 through holes are arranged symmetrically along the axis of the fixed pipe, two through holes are set, correspondingly, locking devices are respectively arranged at the two through holes, so that the pipe body The force is uniform, and the stability of fixing the pipe body is improved.

Further, the elastic element (9) is a spring.

Further, the wing plate is arc-shaped, and a sputum suction hole is provided on the wing plate, so that the shape of the wing plate matches the shape of the face of the human body as much as possible, so that the fixing device can be stably fixed on the human body, and the setting of the sputum suction hole can It is convenient to absorb the secretions produced in the patient's mouth.

Further, the tail end of the wing plate is provided with a fixing hole, and an inch belt is provided at the fixing hole to facilitate the fixing of the fixing device.

Further, the endotracheal tube also includes a joint and an air bag, the joint is fixed on the left end of the tube body, the air bag is sleeved on the outer wall of the tube, and the air bag blocks the connection between the lungs and the outside of the human body, so that the lungs can be inhaled and Exhalation was performed through endotracheal intubation.

The fixing device of the tracheal intubation of the utility model is integrated with the tube body. The fixing tube and the tube body are clamped together by the locking device, which is convenient to use and reduces the risk of the tube falling off. , so that the depth of the tube body inserted into the patient's trachea can be adjusted freely, without other complicated tightening operations, which reduces the workload of medical staff and improves the comfort of patients.
