Description

Technical Field

[0001] The utility model relates to the technical field of negative pressure suction devices, in particular to a negative pressure adjustable drainage device. Background Art

[0002] During surgery and rehabilitation, in order to reduce the impact of fluid accumulation on the patient, it is usually necessary to drain the fluid from the patient's body to the outside through a drainage device. Common drainage devices are usually drainage bags or drainage bottles. When such drainage devices are in use, the interior is usually in a negative pressure state, so as to facilitate the extraction of fluid from the patient's body, thereby improving the efficiency of fluid discharge. However, the internal negative pressure value of common drainage devices is usually fixed. When the fluid accumulation in the drainage device reaches a certain level, it will be in a state of air pressure balance or even the pressure inside the drainage device is higher than the external pressure, which may cause poor drainage of the accumulated fluid or even cause reflux of the accumulated fluid. At present, negative pressure pumps are often used to pump air to adjust the pressure value in the drainage device, but negative pressure pumps are prone to insufficient demand when used by multiple patients, and the cost of negative pressure pumps is relatively high, resulting in some deficiencies in the use of drainage devices.
