Multifunctional double-bag trachea cannula

Abstract

The invention belongs to the technical field of medical trachea cannulas, and particularly relates to a multifunctional double-bag trachea cannula which comprises a tube body, an inner inflation bag and an outer inflation bag. One end of the tube body is a patient end, and the other end of the tube body is a machine end. The side wall of the patient end is provided with an arc-shaped side vent hole indented towards the tube body. The inner inflation bag is formed by connecting a plurality of adjacent concave parts and protruding parts. The outer inflating bag comprises an outwards-protruding first gas bag section, an outwards-protruding second gas bag section, and an arc-shaped connecting section located between and connected with the first gas bag section and the second gas bag section. A flushing and medicine outlet is formed in the portion, above the outer inflation bag, of the tube body. The portions, extending out of the tube body, of an infusion medicine catheter, an outer inflation bag infusion gas catheter and an inner inflation bag infusion gas catheter are fixedly connected side by side. The multifunctional double-bag trachea cannula has the advantages that multi-hole medicine spraying is achieved, tracheal mucosa is not pressed, the blood circulation state is good, glottis is not prone to damage, oxygen supply and sputum aspiration are smooth, and pains of a patient are relieved.

Description

technical field [0001] The invention belongs to the technical field of medical tracheal intubation, in particular to a multifunctional double-bag tracheal intubation. Background technique [0002] Endotracheal intubation is to insert a special endotracheal tube into the patient's trachea through the mouth or nose. This device and technology can provide the best conditions for airway patency, ventilation and oxygen supply, respiratory tract suction and prevention of aspiration. A technique for endotracheal anesthesia and patient rescue. Endotracheal intubation is an important measure to rescue patients with cardiac and respiratory arrest. It is convenient to remove respiratory secretions, maintain tracheal patency, reduce airway resistance, help reduce respiratory anatomical dead space, ensure effective ventilation, and provide conditions for oxygen pressurized artificial respiration and intratracheal drug delivery, tracheal or bronchial intubation Tube is a safety measure f...

Problems solved by technology

[0003] However, during the use of the existing endotracheal tube, the inflatable balloon is easily damaged and leaks, causing secretions and blood to flow into the trachea. In this case, the operation can only be suspended, the endotracheal tube is withdrawn, and a new one is replaced. Endotracheal intubation, which brings a lot of trouble to the operation and pain to the patient

And the existing endotracheal intubation tube is easy to be blocked in the side air vent of patient's end and the hole of lower end during use, and then affects the smooth progress of oxygen supply and sputum suction operation, affects the success of operation; It is straight, and it is easy to poke the trachea and scratch the trachea, causing more pain to the patient; and because the tracheal intubation tube stays in the trachea for a long time, a large amount of saliva will be retained in the patient, on the one hand, it will block the connection between the intubation tube and the trachea. On the other hand, excessive saliva will flow out, which is not conducive to the operation

Once the tracheal intubation and the trachea cannot be kept open, it will easily lead to hypoxia and carbon dioxide retention in the patient, which will easily bring life danger to the patient
