Description
Technical Field
The utility model relates to a right bronchial catheter with three outer cuffs and two side holes.
Background
An anesthesia technique that separates the bilateral pulmonary airway diameters at the bronchial level, called pulmonary isolation, is problematic because of the following problems during thoracic surgical anesthesia: the operation of trachea, bronchus and lung is carried out in the lateral lying position with the affected side upward, after the affected side is opened, the lung is collapsed due to disappearance of negative pressure of the thoracic cavity and the lung is lifted and extruded by the operation, secretion or blood accumulated in the affected side lung is drained to the bronchus and trachea bulge of the healthy side lung, and the secretion and the blood flow into the healthy side bronchus due to gravity factors, so that the healthy side lung is infected and spread, blood clots are blocked, and an airway is blocked. Secondly, during the anesthesia, the mechanical control ventilation is carried out after muscle relaxant is used, generally in an intermittent positive pressure ventilation mode, and the physiological disorder caused by abnormal respiration and mediastinal swing is overcome. However, in the case of bronchial surgery, the bronchus of the patient may be opened, and the patient may not be ventilated by positive pressure due to local air leakage. The chest surgery under the television thoracoscope which is widely developed at present has small wound and quick postoperative recovery, and the lung at the operation side is required to be collapsed during the surgery to observe and operate.
Above-mentioned several circumstances all require only to carry out both sides lung and keep apart and ventilate respectively, can realize: firstly, the healthy side lung is prevented from being polluted by the affected side lung; secondly, when the affected lung and the bronchus are open, the effective ventilation of the healthy lung can be still ensured; the healthy side lung ventilates and the affected side lung collapses, thereby providing clear operation visual field and ensuring the smooth operation of the affected side lung (especially the thoracoscope operation); in addition, different ventilation modes can be performed on the bilateral lungs according to the disease condition and the operation requirement. At present, a double-cavity bronchial catheter is mostly adopted as an appliance for carrying out lung isolation application in thoracic surgery anesthesia.
The prior double-cavity bronchial catheter has the following problems in clinical use:
1. for children or short patients, when the inner diameter of the trachea is thin, the double-lumen bronchial catheter cannot be inserted to realize lung isolation;
2. for patients who have difficulty in mouth opening or can only be intubated through nose and need to be isolated by two lungs, the double-cavity bronchial catheter cannot be intubated to realize lung isolation due to too large pipe diameter and high hardness of the double-cavity bronchial catheter;
3. in addition, the trachea inner diameter and the throat or glottis stenosis are not only considered during intubation, and the dual-cavity bronchial catheter is easy to damage the throat or the glottis due to too large tube diameter and high hardness; 4. after the double-cavity bronchial operation, part of patients still need to be supported and treated by a breathing machine for a period of time, and in order to improve the comfort of the patients and reduce the damage of the air passage, the single-cavity bronchial catheter needs to be replaced, so that one invasive operation is added, and the medical expense is also increased.
