Technical Field
The utility model relates to a tracheal catheter, in particular to a tracheal catheter which can carry out local continuous anesthesia.
Background
Endotracheal tubes are medical devices that are inserted into the trachea and/or bronchi of a patient to create a temporary artificial respiratory pathway for the patient, particularly for patients who are unable to breathe spontaneously.
During the tracheal catheter operation, local anesthesia is generally needed to be performed on the laryngeal part, glottis and other places of a patient so as to ensure that the patient with sensitive reflection such as the laryngeal part, the glottis and the like can cooperate to enable the tracheal catheter to be inserted smoothly. However, over time, the efficacy of the anesthetic is gradually lost, the patient enters the anesthesia recovery period, the sensation of the throat is restored, and the patient can suffer from the intolerance symptoms such as choking cough and the like due to the insertion of the tracheal catheter, so that the patient feels pain. And because of the existence of the tracheal catheter, local anesthesia can not be performed again, and the patient can only tolerate the anesthesia. In addition, the end of the tracheal catheter needs to be kept lubricated at any time to avoid damage to human tissues. The existing mode is that vaseline is smeared at the front end of a tracheal catheter before intubation, but the continuous lubrication time is short, and the whole operation process cannot be covered.

The drug supplementing valve can supplement drugs in one direction only, so that the anesthetic in the cylinder body is prevented from overflowing.
As an improvement, an annular distribution groove is formed in the inner part of the side wall of the far end of the catheter body, and the medicine outlet hole is communicated with the distribution groove. Can surround the medicine distribution 360 degrees around the distal end of the endotracheal tube body, so that the distribution of the anesthetic is more uniform.
Preferably, the medicine outlet hole is formed in the distal end part of the catheter body and the side wall.
The utility model discloses an useful part lies in: the tracheal catheter with the structure can locally administer medicine to parts such as glottis of throat and the like through the medicine administration device after intubation, and the defect that the medicine can not be administered after the conventional tracheal catheter is inserted into the throat of a patient is overcome. Meanwhile, the administration device can provide a continuous and slow administration function, and can lubricate the front end of the tracheal catheter for a long time to avoid damaging the throat of a patient.

Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the specific embodiments.
As shown in fig. 1, 2 and 3, the present invention comprises a catheter body 1 and a balloon 2 disposed on the catheter body 1; and the inflatable balloon 3 is used for inflating the balloon 2, and the inflatable balloon 3 is connected with the balloon 2 by an inflation catheter 4.
The continuous drug delivery device comprises a cylinder body 6 with two closed ends; a piston 7 is arranged in the cylinder 6, and a dosing spring 8 is arranged behind the piston 7; a push plate 9 capable of moving back and forth along the cylinder 6 is arranged behind the dosing spring 8, and a screw 10 is connected behind the push plate 9; the rear end plate of the barrel body 1 is provided with a screw hole, and the screw hole is in threaded fit with the screw rod 10. The barrel 1 is made of transparent materials, and scales are marked on the barrel 1.
