TECHNICAL FIELD

[0001] The utility model relates to medical field, concretely is a drainage bag liquid level alarm. BACKGROUND

[0002] Drainage is the basic technique commonly used in clinical work, and is widely used in patients with dysuria, postoperative and critical illness, and the end of the drainage tube is usually connected with a drainage bag. Nowadays, although surgical techniques are constantly improving, postoperative drainage is still an important method for most doctors to avoid or reduce postoperative complications. Drainage can be used to drain exudate, blood, pus and lymphatic fluid, digestive fluid from the lesion site to the outside of the body to achieve the purpose of diagnosis or treatment. Puncture and drainage is an essential part of patient treatment. In drainage tube care, the observation of the amount of patient drainage is the focus of medical staff. Through observation, the patient's condition can be understood in time to avoid adverse events.

[0003] However, the ordinary drainage bag is commonly used in clinical drainage, which generally does not have an alarm function, and nursing staff need to continuously patrol and check to master the amount of drainage and keep the drainage tube unobstructed.

[0004] In actual work, most of the drainage process is usually double-regulated by the patient himself or his family and medical staff, but it is often impossible to pay attention to the drainage of the patient in time due to various reasons, which easily leads to excessive one-time drainage of the drainage.

[0005] Therefore, it is necessary to design a drainage device alarm that can alarm in time when the predetermined liquid amount is reached, so as to reduce the incidence of adverse events, reduce the workload of nursing staff and improve the satisfaction of patients and nurses.
