Description

Anesthesia atomization device

Technical field

The utility model relates to the field of anesthesia equipment, in particular to an anesthesia atomization device.

Background technique

Endotracheal intubation is a basic operation for respiratory tract management during general anesthesia. However, for patients with difficult airways, tracheal intubation after induction of anesthesia is full of challenges. In severe cases, tracheal intubation or inability to ventilate or even death may occur. Therefore, domestic and foreign airway management guidelines recommend awake endotracheal intubation to preserve spontaneous breathing as the first choice for patients with high risk of difficult airway. Adequate surface anesthesia of the throat and tracheal mucosa is a prerequisite for awake tracheal intubation. For critically ill patients who require tracheal intubation and ventilatory support, in order to reduce the stimulation of tracheal intubation, adequate mucosal surface anesthesia will also greatly reduce serious cardiovascular and cerebrovascular complications caused by circulatory fluctuations caused by tracheal intubation. occurrence of the disease. The key to topical anesthesia is the delivery of local anesthetic drugs in an atomized state. The anesthetic drug atomizer designed in this way can fully atomize the local anesthetic drug, so that the atomized drug particles can be inhaled with the air flow, thereby producing a reliable surface anesthesia effect.

Conventional anesthesia nebulizers are connected to an atomizing nozzle through a metal tube. The anesthetic is extracted by siphoning under the action of air flow, and the liquid anesthetic is mixed with gas and then delivered to the atomizing nozzle for output. However, a large amount of local anesthetic drugs need to be poured into the glass bottle of the anesthesia atomizer in advance, which makes it impossible to use what is needed, resulting in a waste of local anesthetic drugs. At the same time, since the atomizer is not for one-time use and needs to be cleaned after each use and sent to the supply room for disinfection before use, there are disadvantages of cross-contamination and inability to obtain it in time without disinfection. In addition, traditional local anesthetic drug atomization devices often require high-flow oxygen. The operation process is limited by the possibility of high-flow oxygen supply, and cannot meet the needs of convenient access and quick operation during first aid; and it is easy to cause the infusion of the drug during the infusion operation. Contamination, there is also the hidden danger of foreign matter entering the atomization channel and causing the atomization nozzle to be clogged, making it difficult to meet clinical needs for the anesthesia atomization process.
