Description

Technical Field

[0001] The utility model relates to the field of nursing teaching, in particular to a pressure-adjustable sealed bottle for nursing teaching. Background Art

[0002] In nursing education, medicine dispensing exercises are required. Specifically, multiple medicines are mixed in a solution in precise proportions, and then the mixed liquid medicine is accurately extracted with a syringe. However, since it is used for practice, using real medicines will cause waste of medicines. Therefore, water is often used instead of medicines during practice, but water generally does not produce pressure changes after mixing. In actual scenarios, many medicines will produce pressure changes after mixing. This leads to students often operating accurately during practice in school, but in actual work, problems such as drug splashing occur when aspirating the liquid medicine, resulting in drug waste. What's worse, the splashed medicine can cause damage to parts of the body.

[0003] Therefore, there is an urgent need for a pressure-adjustable nursing teaching sealed bottle that can solve the above problems. Utility Model Content
