Problems solved by technology

Clinically, in order to suppress this adverse reaction, a large amount of analgesia, sedation or muscle relaxants are required, which is often not conducive to the observation of the condition, and greatly increases the number of days of hospitalization and thus increases the cost of the patient.

Embodiment 1

[0028] Such as Figure 1-Figure 5 As shown, a tracheal tube capable of airway topical anesthesia includes a main body 1, one end of the main body 1 is formed with an external connector 2, which is used to communicate with a ventilator or external air to facilitate the patient's breathing, and the other end of the main body 1 is formed There is a tapered mouth 4, which is easy to insert into the throat of the patient. The position of the tapered mouth 4 near the mouth of the nozzle is a wedge-shaped structure. The main body 1 includes an inner ventilation tube 11 and an outer coating tube 12. The outer coating tube 12 is nested in the inner ventilation tube. The outside of the trachea 11 is glued and fixed together with the inner ventilation tube 11, and the outer coating tube 12 is formed with a drug delivery thin tube 13 for the delivery of anesthetic liquid, and the drug delivery thin tube 13 extends to the inside of the tapered mouth 4 One end is formed with a micro-spray h...

Embodiment 2

[0037] Such as Figure 6 As shown, the content of this embodiment is roughly the same as that of Embodiment 1, except that:

[0038] In this embodiment, the thin drug delivery tube 13 is tangent to the outer wall of the main body 1, and the micro spray holes 17 are distributed on the tangent line, which facilitates the molding of the thin drug delivery tube 13 inside the outer coating tube 12 during processing, reducing the difficulty of the production process .

[0039]The working principle of the present invention is: the main pipe body 1 is made of medical materials. When in use, the brand new catheter is unpacked, and then the conical mouth 4 is inserted into the throat of the patient. The insertion depth is observed through the scale line 8. When it is inserted into the designated place Finally, insert the needle into the inflatable joint 7 to inflate, so that the air bag 5 is inflated and stuck in the throat of the patient, and the trachea is fixed, and then the needle ...

Abstract

The invention relates to the technical field of medical supplies, and particularly discloses a tracheal tube capable of realizing airway surface anesthesia. The tracheal tube comprises a main tube body, wherein an outer connector is formed at one end of the main tube body, a conical nozzle is formed at the other end of the main tube body, the main tube body comprises an inner ventilation tube andan outer covering tube, the outer covering tube is nested outside the inner ventilation tube and fixed with the inner ventilation tube in a glued manner, a drug delivery tubule is formed in the outercovering tube, and a micro medicine spray hole is formed in the end, extending into the conical nozzle, of the drug delivery tubule. The tracheal tube has the beneficial effects as follows: the surface of upper and lower throat parts of the glottis of an intubated patient is anesthetized to reduce the reaction degree of the patient on intubation stimulation: 1, local anesthesia and intubation arecompleted once conveniently, so that injury caused by throat spray and intubation secondary operation is reduced; and 2, through intermittent trachea surface anesthesia of a severe intubated patient,the tolerance of the patient to a catheter is improved and the comfort of the patient is improved.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to an endotracheal tube capable of surface airway anesthesia. Background technique [0002] Clinically, endotracheal intubation during general anesthesia almost always has varying degrees of intubation reactions, mainly manifested as: coughing, increased heart rate, increased blood pressure, and even acute cardiovascular and cerebrovascular events. In order to suppress this choking reaction, at present, the throat spray assembly is mainly used to spray local anesthetics on the throat, then take it out, and then carry out tracheal intubation. This also improves the endotracheal intubation response to a certain extent. However, the throat spraying and intubation are divided into two parts, and the operation is cumbersome, and the two operations may aggravate the bleeding and swelling of the throat, causing adverse consequences. Some also perform cricothyropuncture to reduce...
