Bite-prevention type breather catheter used for cardiovascular medicine nursing

Abstract

The invention discloses a bite-prevention type breather catheter used for cardiovascular medicine nursing. The bite-prevention type breather catheter comprises a main body mechanism, a tongue depressor and a mouth support mechanism, wherein telescoping mechanisms are symmetrically installed on the inner side of the main body mechanism, the right sides of the telescoping mechanisms are connected with limiting mechanisms, the tongue depressor is fixed to the lower right corner of the main body mechanism, and the outer wall of the tongue depressor is wrapped with a protection sleeve. The lower portion of the tongue depressor is connected with a connection mechanism, the mouth support mechanism is arranged on the outer side of the main body mechanism, the front side of the main body mechanismis symmetrically provided with connecting buckles, and the outer sides of the connection buckles are connected with fixing mechanisms. Many parts of the breather catheter are prepared from an elasticsilicon material, the material is soft, the surface is smooth, so that the damage of the main body mechanism and the tongue depressor to the oral mucosa of a patient is effectively prevented, and theinjury caused when the patient occludes the teeth is further prevented. By arranging the telescoping mechanisms and the limiting mechanisms to be cooperatively buckled to the inner side of the teeth,liming and fixing are conducted, and the catheter is easily prevented from sliding out of the mouth of the patient.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an anti-bite ventilation catheter for nursing in cardiovascular medicine. Background technique [0002] Cardiac arrest refers to the sudden termination of cardiac ejection function, the disappearance of aortic pulse and heart sound, and severe ischemia and hypoxia of important organs (such as the brain), leading to the end of life. This unexpected sudden death is also called sudden death in medicine. According to the "China Cardiovascular Disease Report" released in 2015, the incidence of sudden cardiac death is 41.8 / 100,000 people, and the number of deaths due to cardiac arrest is as high as 540,000 every year. The key to successful rescue, especially within 4 minutes, is more critical. The time to start cardiopulmonary resuscitation has a great relationship with the success rate of resuscitation, that is, the survival rate will decrease by 10% every time the rescue is e...

Problems solved by technology

[0004] The purpose of the present invention is to provide an anti-bite type ventilation catheter for cardiovascular internal medicine nursing, which solves the problem that the existing disposable ventilation catheter is hard in texture, has been shaped before it is inserted, and sometimes it is difficult to insert and easy to cause damage to the oral mucosa of the patient. Injury, it is not only difficult to fix after being placed inside the mouth, but also not easy to connect to the simple respirator
