Abstract

The invention relates to a medical instrument, and particularly relates to a negative pressure drainage apparatus. The negative pressure drainage apparatus disclosed by the invention comprises a drainage ball and a drainage pipe connected to the drainage ball. The negative pressure drainage apparatus is characterized in that a filter plate is arranged inside the drainage pipe; and a spine section is arranged on the filter plate. The negative pressure drainage apparatus is simple in structure and convenient to use, drain can quickly enter the drainage ball, the drainage pipe is hardly blocked, and the workload of a medical worker is reduced when pain of a patient is relieved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, and more specifically relates to a negative pressure drainage device. Background technique [0002] The wound exudate of the patient needs to be drained after surgery. The purpose of the drainage is to guide the pus and blood accumulated between human tissues or body cavities during the operation to the outside of the body, so as to prevent postoperative infection and affect wound healing. The existing drainage devices are likely to cause blockage of the drainage tube during use, thereby affecting the drainage effect or requiring repeated insertion of the drainage device in the patient's body to increase the pain of the patient's operation. [0003] The authorized announcement number is CN86201263U, and the announcement date is March 18, 1987. The Chinese utility model patent discloses a medical negative pressure drainage device. The medical negative pressure drainage device disclosed...
