Description

Technical Field

[0001] The utility model relates to the technical field of plastic surgery, in particular to a portable negative pressure suction device. Background Art

[0002] Plastic surgery is a branch of surgery, also known as reconstructive surgery or plastic surgery. Its treatment scope mainly includes trauma and diseases of the skin, muscles and bones, and congenital or acquired defects and deformities of tissues or organs. A vacuum suction device is a tool that creates a negative pressure state on its suction head through a certain method, and the material outside the suction head is squeezed toward the suction head, thereby achieving the "suction" effect. After plastic surgery, a vacuum suction device is often used to suction and repair the wound, such as a portable vacuum suction device.

The utility model does not require manual squeezing of the airbag and manual fixing of the drainage tube, and can also clean the wound surface, which is beneficial to the healing of the wound surface, reduces the burden on patients, and improves portability. Although the device can clean the wound surface and is beneficial to the healing of the wound surface, the medical film and sponge pad of the device are fixed. For some non-planar wounds or narrow wounds of patients after plastic surgery, such as the surface of the nose and the smaller parts of the corners of the eyes, they cannot be fitted, resulting in insufficient negative pressure suction and poor therapeutic effect. Therefore, suction cups with different shapes are proposed to facilitate negative pressure suction of the smaller parts of the nose surface and the corners of the eyes, which is beneficial to treatment. A portable negative pressure suction device is provided. Utility Model Content
