Problems solved by technology

[0008] Compared with the sprayer of the sprayer method for spraying in the past, the pipe clogging phenomenon of the above-mentioned powder sprayer is reduced, and the spraying force is improved. The injection through the duct forms a 1-way air flow, so it is difficult to improve the injection force satisfactorily
[0009] Moreover, since there is moisture such as body fluids in the body, when the powder injector is used, the moisture may flow back to the medical catheter inserted into the body, and the above-mentioned moisture may cause the powder with high water absorption to agglomerate and cause the catheter to block. However, conventional powder injectors including the above-mentioned powder injectors do not have technical units for solving the above-mentioned problems.

Abstract

The present invention provides a bidirectional airflow dispenser for powder injection and a powder injector including the same. The present invention can achieve smooth powder spraying by adopting a bidirectional air flow method that separately forms the air flow for spraying the powder and the air flow for transferring the powder from the container to the spray nozzle.

Description

technical field [0001] The present invention relates to a 2-way air flow dispenser for powder injection and a powder injector including the same. Background technique [0002] Bleeding management is extremely important during surgery. Loss of blood can create multiple problems for the patient, on the other hand, the presence of blood in inappropriate locations can be detrimental to normal tissue or potentially prevent the doctor from viewing the surgical site. Such bleeding can cause problems even during minimally invasive procedures (eg, laparoscopic surgery). [0003] Gastrointestinal bleeding is a clinical disease commonly encountered in clinical practice. More than 80% of gastrointestinal bleeding occurs in the upper gastrointestinal tract. Upper gastrointestinal bleeding is caused by bleeding in esophagus, stomach and duodenum. A disorder in which vomiting blood or bloody stools occurs. More than 90% of upper gastrointestinal bleeding can be confirmed by endoscopic e...
