Interventional drug delivery equipment for treating atrophic gastritisTechnical Field
The invention relates to the technical field of interventional medicine delivery equipment, in particular to interventional medicine delivery equipment for treating atrophic gastritis.
Background
Atrophic gastritis is also called chronic atrophic gastritis, most of which are stomach diseases caused by helicobacter pylori infection or unhealthy eating habits, often manifested by symptoms such as dull pain in the upper abdomen, fullness, eructation or inappetence, and has a certain canceration probability, which is a general term for a plurality of harmful factors for human health. The interventional therapy needs to be conducted under the guidance and monitoring of the imaging equipment, can accurately and directly reach the lesion part, and has no great trauma.
Western medicine has no specific therapy for atrophic gastritis, and has no stimulation to gastric mucosa protecting agent, gastric motility agent, acid making agent, helicobacter pylori positive person, etc. However, these methods have poor therapeutic effects on wounds in the upper part of the stomach, and the main reason is that it is difficult to effectively contact the upper part of the stomach for a long period of time after the medicament is dissolved in gastric acid, so that the medicament is difficult to reach the wounds in the upper part of the stomach, and thus the therapeutic effect is reduced, and the conventional device is difficult to accurately spray the medicament on the wounds in the upper part of the stomach, so that accurate medicament delivery cannot be realized.
