Technical Field

The embodiment of the invention relates to the technical field of medical equipment, in particular to a negative pressure drainage device.

Background

During and after internal surgical operations, the fluid drainage can avoid the accumulation of exudates, weeping fluids or other fluids in the incision, and the accumulation of the fluids can influence the healing of the incision and can also cause the local pressure to be increased so as to cause other complications.

At present, the commonly used drainage device has gravity drainage and disposable high negative pressure drainage.

Gravity drainage when drainage is carried out, the drainage pressure mainly depends on the height difference of two ends of the drainage tube. While the use of gravity drainage devices is inconvenient due to the complexity of the environment, due to the differences in personnel.

Disposable high negative pressure drainage device, drainage negative pressure is too big can lead to drainage speed too fast to make various unexpected emergence, if: thoracic surgery pleural effusion drainage too high pressure can lead to renaturation pulmonary edema, and peritoneal effusion negative pressure drainage too fast can lead to heart failure.

In some drainage, the drainage pressure cannot be high negative pressure, which may cause serious complications, such as: in lumbar puncture and cerebrospinal fluid drainage, once negative pressure drainage is not timely found and treated, cerebrospinal fluid drainage can be caused to be lost too much, intracranial pressure is reduced, cerebral hernia can be caused, and life can be endangered; when drainage is performed after a brain surgical operation or drainage is performed through a cranial bone drilling hole, cerebrospinal fluid can be communicated with a drainage tube, once negative pressure drainage is not timely found and processed, the cerebrospinal fluid can be excessively lost, intracranial negative pressure can be generated, the occurrence of cerebral hernia can be caused, and the life can be threatened.

In these drainage applications, it is desirable to ensure that the height of the drainage fluid reservoir is located in close proximity to the drainage outlet of the drain tube, i.e., that the drainage reservoir must be placed in a horizontal plane with the drainage outlet of the drain tube. Care must be taken in placing the drainage container to avoid placing the drainage container in a lower position. However, in clinical practice, since the personnel involved in management are very complicated, including doctors, nurses, nursing staff, family members and the like, once the management is not in place, the drainage fluid storage container is placed at a lower position to cause negative drainage of cerebrospinal fluid, and the intracranial hypertension and even cerebral hernia occur for a long time, which threatens the life safety of patients.

And for disposable negative pressure drainage device, only can change new negative pressure drainage device after the negative pressure in the drainage device of medical care in-process consumes, this brings great economic burden for the patient, has also produced more medical waste simultaneously.
