Abstract

The invention discloses a medical negative pressure drainage ball for squeezing backflow prevention. The drainage ball comprises a ball body, a drainage pipe and protection covers. A liquid dischargepipe is connected with the lower portion of the ball body. A liquid discharge opening is formed in the liquid discharge pipe. The outer side of the liquid discharge pipe is connected with a connectingbelt. A connector is installed above the ball body. The drainage pipe is located above the connector. A protection block is installed on the drainage pipe. A pipeline hole is formed in a sealing plate. A slider is arranged on the outer side of the sealing plate. The protection covers are located on the outer side of the ball body. A binding belt is connected to the connecting block and provided with a button. The two hemispherical protection covers are clamped and connected with the ball body through the binding belt and the button, the ball body can be conveniently protected, the liquid backflow phenomenon caused when a patient squeezes the drainage ball is avoided, the normal drainage work of the drainage ball is guaranteed, and meanwhile the safety of hematocele drainage is increased.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a medical negative pressure drainage ball for preventing extrusion backflow. Background technique [0002] Negative pressure drainage ball is a commonly used medical auxiliary device in the medical field. It is mainly used to connect to the gastric tube after gastrointestinal surgery to help attract digestive juice and decompress the gastrointestinal tract. Patients need to install a drainage tube at the incision after surgery. And the drainage ball, which drains the blood and other fluids produced by the postoperative wound and excretes them from the body. [0003] Due to the uncertain fixed position of the negative pressure drainage balls currently on the market, it is easy for patients to touch and press them when using the negative pressure balls, causing the drained liquid to be squeezed back, and sometimes even punctured, thus affecting The use of the negative pr...
