Negative pressure fixing seat

Abstract

The invention relates to a negative pressure fixing seat. The negative pressure fixing seat is suitable for medium-term and short-term fixation, cupping and pressure drug delivery on an irregular plane. The negative pressure fixing seat is provided with an annular base, wherein an annular sealing material is arranged in the annular base, the sealing material is one of a plastic deformation material, a mud plastic solid, a solid-liquid mixture and a fluid material, the surface of the sealing material is provided with 0-1 protective thin layer, and the annular base is integrally connected with anegative pressure shell plate or is in compressed connection with the negative pressure shell plate through a pressing ring. The negative pressure fixing seat has the advantages that the fixed load is large, the requirements on the use condition of the surface of the plane are low, the use condition of an original cupping device is lowered, the use functions and range of the original cupping device are increased, the cost is low, the fixation is firm, reinforcement can be performed in the middle, repeated use can be achieved, the fixation position is flexible, the surface of the fixed plane is not damaged, the fixing pressure is controllable, and the fixing time is long.

Description

technical field [0001] The invention relates to a negative pressure fixation seat, which is suitable for medium and short-term fixation, cupping and pressure administration on irregular planes. Background technique [0002] The medium and short-term fixing methods on traditional planes and approximate planes are self-adhesive paste and ordinary negative pressure exhaust fixation. The disadvantages are that the fixed load is small, the requirements for flatness and rigidity of the plane surface are high, and the fixation is not firm. , The middle cannot be strengthened, and the surface of the fixed plane cannot be destroyed, the reuse rate of self-adhesive paste is low, and the fixing time of ordinary negative pressure exhaust is too short. Contents of the invention [0003] The object of the present invention is to provide a device that can fix a large load, have low requirements on the flatness and rigidity of the plane surface shape, reduce the use conditions of the orig...
