Description

Anesthetic spraying tubule for tracheal surface anesthesia

Technical Field

The utility model relates to a medical appliance, in particular to an appliance for surface anesthesia of trachea.

Background

The inhalation of the airway foreign body is a common respiratory system emergency of children, particularly, children aged 1-3 years are frequently seen, the life of the children can be endangered after the occurrence of tracheal foreign bodies, and the foreign bodies need to be taken out by a medical doctor in the department of ophthalmology and otorhinolaryngology under a specific instrument. Specific instruments include thicker rigid bronchoscopes, graspers, aspirators, and the like. The procedure can be summarized as follows: after the infant general anesthesia (generally, the non-tracheal intubation keeps the spontaneous respiration general anesthesia), a hard bronchoscope is placed into an airway by a statement, after a foreign body is seen, the surrounding secretion is removed by a suction apparatus, and then the foreign body is clamped by a grasping forceps until the foreign body is taken out.

The foreign body of trachea takes out the art, and the operation occupies the respiratory track, and the air flue control degree of difficulty is big, and five sense organ branch of academic or vocational study doctors need experienced anesthesia doctor to cooperate and just can accomplish smoothly. The main anesthetic process is summarized as follows: 1. after the infant enters an operating room, performing life monitoring, and inhaling sevoflurane until the concentration reaches a certain value, wherein consciousness and body movement reactions of the infant disappear; 2. opening a venous channel, performing intravenous injection of propofol in a target-controlled infusion mode, and gradually and slowly increasing the target-controlled concentration to enable the infant patient to be in a deep anesthesia state; 3. placing a laryngoscope, and spraying lidocaine to the vicinity of the glottis by using a laryngeal anesthesia tube to perform surface anesthesia; 4. in the whole process, the vital signs and tidal volume changes of the infant need to be closely monitored, and after comprehensive judgment of anesthesia, the operation is started by the ENT department physician. The difficulty of anesthesia in the tracheal foreign body extraction operation lies in that: the operation has large stimulation to the infant, and the infant is easy to have body movement, breath holding, choke cough and even bronchospasm when the anesthesia is shallow, thereby threatening the life safety of the infant. However, when the anesthesia is too deep, the spontaneous respiration of the infant patient is inhibited, and the problem of oxygen deficiency needs to be solved by controlling ventilation, but foreign matters, blood and tissue fragments can be blown into the deep part of the bronchus by controlling ventilation, so that the operation difficulty is increased. The operation stimulation of the infant mainly comes from the placement of a thicker hard bronchoscope in an air passage and the friction between foreign bodies and the air passage wall when the foreign bodies are grabbed, so that ideal surface anesthesia in the air passage is a key technology for the successful operation.

At present, the method，The auxiliary instruments used for airway anesthesia operation are a visual laryngoscope, a hemp spraying tube, a throat part and a glottis structure All can be clearly displayed on the display screen of the visual laryngoscope, the hemp spraying tube is a hard tube, the front end is provided with a nozzle, and the hemp spraying tube is larger than the visual laryngoscope The thickness of the mixture is coarse,the laryngotracheal tube nozzle can only reach the glottis position, and the surface anesthesia in the air flue is mainly realized through 3 (put into the laryngoscope, spray lidocaine near the glottis mouth with the laryngotracheal tube and carry out surface anesthesia) in the above-mentioned anesthesia process, and the main principle is that the lidocaine that the laryngotracheal tube sprayed at the glottis mouth enters the air flue through the breathing of the infant, thereby plays the effect of surface anesthesia. In clinical practice, we find that step 3 needs to be repeated for a plurality of times to obtain a better tracheal surface anesthesia effect, because the local anesthetic sprayed on the vocal orifice only partially acts on the surface mucosa of the far end of the trachea along with the breathing of the infant, and the far end of the trachea and the bronchus are not fully anesthetized. However, step 3 cannot be repeated too much, limited to the risk of intoxication due to overdosing of local anesthetic.
