Description
Technical Field
The utility model relates to the technical field of medical equipment, particularly, relate to a laryngeal mask that can compatible intranasal high flow assists to ventilate.
Background
Fiberoptic bronchoscopes (FBs, abbreviated as bronchofiberscopes) are one of important means for diagnosing and treating respiratory diseases, and have wide indications, such as malignant lung tumor, infection, diffuse lung diseases, airway diseases and the like. In the conventional fiberbronchoscopy under local surface anesthesia, a patient is in a waking state, and the stimulation and operation of the body of the endoscope on tracheal mucosa bring about strong chocking cough and fear to the patient. In addition, the operation and the breathing oxygen supply share the air passage in the bronchofiberscope examination process, and the bronchofiberscope stimulates the air passage, so that the larynx and the bronchospasm are often induced, and the risk of hypoxemia in the operation is obviously increased. At the present stage, the technique of bronchofiberscope examination under general anesthesia has been widely accepted, the improved laryngeal mask is applied to the bronchofiberscope examination under general anesthesia to become a hot spot in recent years, when the laryngeal mask is applied to the bronchofiberscope examination, the laryngeal mask is not required to be lifted and fixed, and the glottis is well opened and the endoscope enters smoothly, so that the consciousness of a patient disappears, the patient does not choke and move, an examining doctor can operate the laryngeal mask easily, the interference of breathing is not controlled, the patient does not need to worry about oxygen deficiency, and the examination and treatment time is not limited. When a intubation type laryngeal mask is also applied, the nasal catheter is placed in the laryngeal mask to absorb oxygen, and the bronchofiberscope enters the examination from the laryngeal mask. However, the laryngeal mask needs to be placed at a deeper anesthesia depth, and for the patients with more senile asthenia complications, particularly for the application of muscle relaxing medicines, the recovery period is generally longer, so that the painless bronchofiberscope examination cannot be as fast as the painless gastrointestinal scope examination and is convenient to popularize; especially run into the operation in the patient that bleeds greatly, the department of respiration doctor will attract hemostasis, and the breathing machine can not breathe the oxygen suppliment through the trunk line this moment, and the oxygen deficiency condition is aggravated more, and the operation demand is accomplished fast under the condition of patient's transient oxygen deficiency, otherwise will bring the operation risk, causes the operation accident even. Recent studies have shown that: for patients with difficult airway and patients with severe hemorrhage in operation, if a technology of giving high-flow oxygen (15L/min-70L/min) through nose is adopted during intubation, the oxygen absorption amount of the patients can be improved, and the oxygen deficiency time of the patients can be shortened.
Therefore, how to solve the using defects of the existing laryngeal mask in the operation process, improve the effective oxygen supply amount of patients with difficult airways and patients with severe hemorrhage in the operation due to obesity and the like, and shorten the oxygen deficiency time of the patients, so as to design the laryngeal mask capable of giving consideration to nasal high-flow auxiliary oxygen inhalation, and the technical problem to be solved by technical personnel in the field is always needed.
SUMMERY OF THE UTILITY MODEL
The utility model provides a problem be: the laryngeal mask is compatible with nasal high-flow auxiliary ventilation, can not only be used for breathing and supplying oxygen through a main tube inserted into the oral cavity, but also can be used for assisting oxygen inhalation through the nasal cavity, and is beneficial to ventilation of patients with difficult airways and patients with severe hemorrhage in the operation.
In order to solve the problem, the utility model provides a can compatible intranasal high flow assists laryngeal mask of ventilating, including being responsible for and being responsible for the cover bag that one end is connected, be equipped with the air guide duct that is linked together with the inner chamber of cover bag in being responsible for, be close to and offer the supplementary air vent that is linked together with the air guide duct on the outer wall of the person in charge of the department that is linked together of inner chamber and air guide duct, supplementary air vent is arranged in will leading to the inner chamber via the oxygen drainage that the nostril flowed in.
Compared with the prior art, the utility model, useful part lies in: the utility model discloses a set up the supplementary air vent that is linked together with the air duct of being responsible for on the outer wall of being responsible for, will flow into to the inner chamber of cover bag via the nostril with the help of supplementary air vent, and then mix with the oxygen in the inner chamber that gets into the cover bag via the air duct of being responsible for, like this alright provide dual oxygen suppliment guarantee for the patient in the operation, improve patient's oxygen uptake volume, solve current laryngeal mask because of the not enough a great deal of problem that causes of oxygen supply when using, especially can ensure because of reasons such as obesity lead to difficult air flue patient and operation in the patient's of heavy bleeding operation safety.
Preferably, the auxiliary vent hole is a plurality of auxiliary vent holes extending in the longitudinal direction of the main tube. The auxiliary ventilation holes are usually provided in two rows, each row is provided with a plurality of auxiliary ventilation holes, so that oxygen flowing from the nostrils can enter the inner cavity of the mask bag more, and oxygen absorption of a patient can be improved.
