Bronchial occluder with double bags

Abstract

The invention discloses a bronchial occluder with double bags. The bronchial occluder consists of a trachea cannula and a bronchial blocking pipe with double bags, wherein the lower end of the trachea cannula is provided with trachea cannula bags connected with inflation valves of the trachea cannula bag through a trachea cannula guide pipe, the bronchial blocking pipe with double bags passes through the trachea cannula and is connected with the trachea cannula, and the upper end of the bronchial blocking pipe with double bags is provided with a caped blocking plug and two inflation valves of the trachea cannula bag; each inflation valve of the trachea cannula bag is respectively connected with the trachea cannula bag through the bronchial blocking pipe with double bags. The different bags can be adjusted to realize partially blocking an opening between the superior lobe of left lung and the inferior lobe of left lung / a part between superior lobe of right lung and medium inferior lobe of right lung during surgery, therefore the flexibility of airway management can be improved, the breathing and circulating stability of a patient can be ensured maximally, and the safety guarantee can be provided for the successful operation of the surgery and the successful recovery of a patient after the surgery.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and is an airway management device used in thoracic surgery anesthesia, specifically designing a double-cuff bronchial occluder. Background technique [0002] my country has a huge population, and in many areas it is a high-incidence area for esophageal cancer and lung cancer. At the same time, with the increasing degree of environmental pollution, the incidence rate is increasing year by year, and the number of operations is also increasing. [0003] Patients undergoing thoracic surgery have the particularity of the department. The patient's own disease will have a negative impact on cardiopulmonary function, and thoracotomy will bring significant changes to the normal physiological mechanism of the patient. With the aggravation of domestic population aging and the continuous improvement of clinical treatment level, the number of elderly patients undergoing thoracic surgery is increasing...

AI Technical Summary

Problems solved by technology

[0005] At present, the most commonly used airway management method in clinical thoracic surgery is the use of double-lumen bronchial intubation or bronchial occluder, which can achieve the effect of completely collapsing the lung tissue on the surgical side and can meet clinical needs, but these two devices Both make the lung tissue on the surgical side of the patient completely collapsed, and the patient can only exchange gas through the lung on the other side. This huge difference from the normal physiological state will have a significant impact on the patient, most often manifested as oxygen The reduction of the partial pressure and the increase of the partial pressure of carbon dioxide can affect the circulation, hinder the normal operation, endanger the health of the patient, and even endanger the life of the patient.
