Problems solved by technology

At present, continuous micropump injection of sedatives is usually used to increase the tolerance of patients with tubes, but the patient’s long-term sedative sleep state is not conducive to recovery, and the stimulation of the tracheal tube to the trachea will increase respiratory secretions, increase the chance of lung infection, and , the lesions of the two lungs may be different, and the clinical treatment measures required for the different conditions of the two lungs will also be different

Abstract

The invention discloses a double-cavity trachea cannula with an accurate dosing function. The double-cavity trachea cannula with the accurate dosing function comprises a trachea cannula assembly and a dosing assembly; the trachea cannula assembly comprises a multi-cavity catheter, a left bronchial catheter, a right bronchial catheter, a main sleeve bag and an auxiliary sleeve bag; the main sleeve bag is arranged on the multi-cavity catheter in a sleeving mode, the auxiliary sleeve bag is arranged on the left bronchial catheter or the right bronchial catheter in a sleeving mode, and the main sleeve bag and the auxiliary sleeve bag are connected with a sealing valve through gas filled catheters correspondingly; the multi-cavity catheter is provided with three cavities, one cavity is used for dosing, one ends of the other two cavities communicate with the left bronchial catheter and the right bronchial catheter correspondingly, and the other ends of the other two cavities communicate with a breathing machine connector; and the dosing assembly comprises a medical sprayer and a filter, a discharging port of the medical sprayer is connected with a feeding port of the filter through a first catheter, and a discharging port of the filter is connected with a first cavity of the multi-cavity catheter through a second catheter. The double-cavity trachea cannula can dose to lungs on the two sides simultaneously, or dose to a lung on one side, is convenient to use, and beneficial for recovery of patients, stable and reliable.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a double-lumen endotracheal intubation tube for precise medication. Background technique [0002] Double-lumen tracheal intubation is used for respiratory management after anesthesia or respiratory support therapy for some severe diseases. When the disease requires the retention of the endotracheal tube, the stimulation of the catheter during intubation, stimulation of sputum suction, or operation during extubation often lead to significant cardiovascular responses and obvious coughing, causing severe discomfort and even accidents. The above discomfort reactions are generally eliminated by early extubation, but this increases the risk. At present, continuous micropump injection of sedatives is usually used to increase the patient's tolerance to the tube, but the patient's long-term sedative sleep state is not conducive to recovery, and the stimulation of the tracheal tube to the...
