Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1 to 3, a high-frequency jet ventilation tracheal catheter comprises a tracheal catheter body 1, a tracheal catheter cuff 2 and a cuff inflation head 3, wherein the tracheal catheter cuff 2 is inflated and deflated through the cuff inflation head 3; the head end of the endotracheal tube body 1 is connected with a tee joint 5, and is connected with a threaded tube 6 and an inserted bronchofiberscope 7 through the other two ports of the tee joint 5;
the high-frequency jet catheter 4 is attached to the outer side wall of the endotracheal tube body 1, the endotracheal tube cuff 2 is positioned between the tail end of the endotracheal tube body 1 and the tail end of the high-frequency jet catheter 4, and the head end of the high-frequency jet catheter 4 can be connected with a high-frequency jet respirator and ventilates the lungs of the patient on the non-bleeding side through the tail end of the high-frequency jet catheter 4; specifically, the tail end of the finger is inserted into one end of the trachea of the patient, and the head end of the high-frequency jet catheter 4 on the tracheal catheter body 1 does not pass through the tracheal catheter cuff 2; the tail end of the high-frequency injection catheter 4 is a closed blind end, a plurality of side holes 9 are formed in the position, close to the tail end, of the high-frequency injection catheter 4, specifically, the side holes 9 are distributed at intervals along the extending direction of the high-frequency injection catheter 4, and when the high-frequency injection catheter 4 is connected with a high-frequency injection respirator, gas is sprayed out of the side holes 9, so that the gas can enter the side lung bronchus which does not bleed.
In this embodiment, the head end of the high-frequency injection conduit 4 is provided with a connector 8 for connecting a high-frequency injection ventilator, so as to facilitate quick and firm connection.
In this embodiment, the internal diameter of high frequency injection pipe 4 is 1 ~ 2mm, and 1 internal diameter of common endotracheal tube body is 5.0mm, 5.5mm, 6.0mm, 6.5mm, 7.0mm, 7.5mm, 8.0mm, 8.5mm, and the internal diameter model of high frequency injection pipe 4 is also big for endotracheal tube body 1 model.
The working principle of the embodiment is as follows: when the tracheal catheter is used, a patient can insert a tube under the general anesthesia state to carry out bronchofiberscope 7 examination; when a patient does not suffer from a large hemorrhage in a bronchus on one side, the high-frequency jet catheter 4 has the same effect as a common tracheal catheter, the high-frequency jet catheter 4 is in an unused state, the tracheal catheter cuff 2 is positioned in the upper section of the trachea of the patient, after the three-way joint 5 is connected, one end of the three-way joint 5 is connected with the screwed pipe 6 of the anesthesia machine for ventilation, and the bronchofiberscope 7 passes through the tracheal catheter body 1 through the other end of the three-way joint 5 and enters the lung to perform examination; once the bronchofiberscope 7 takes place big hemorrhage in the air flue after the biopsy, can loosen the endotracheal tube cuff 2 that originally is located patient's trachea upper segment, adjust the intubate position afterwards, put endotracheal tube cuff 2 into the main tributary trachea opening of the side lung that bleeds, and reuse cuff inflation head 3 to inflate endotracheal tube cuff 2 and make its shutoff bleed in one side lung, prevent to bleed and get into in the other side lung, connect high-frequency injection pipe 4 with high-frequency injection breathing machine work, gaseous side opening 9 that gets into the side lung that does not bleed through the terminal side opening of high-frequency injection pipe 4, guarantee oxygen and, and bronchofiberscope 7 is suction, hemostasis in the side air flue that bleeds.
Compared with a double-cavity tracheal catheter for lung isolation, the tracheal catheter can ensure that a larger bronchofiberscope 7 enters the bleeding side lung for suction and hemostasis, and the efficiency is higher; for patients with poor lung function, oxygen can be better ensured because the high-frequency jet ventilation is carried out on the lung on the other side (the lung on the side without bleeding); compared with a double-cavity tracheal catheter, the optimal position of the intubation is difficult to adjust, the tracheal catheter is easier to intubate and easy to adjust.
