The utility model provides a kind of to prevent and cure phlebitis indwelling needle patch with drug sustained release and observation window, including indwelling needle patch body, the indwelling needle patch body includes film baseband, bottom layer anti-adhesion release paper, circular puncture observation window and drug sustained release layer, the film baseband is divided into film baseband front side area and film baseband rear side area, and film baseband front side and film baseband rear side are fixed on bottom layer anti-adhesion release paper, and the surface edge of film baseband is fixed with frame film holding.The patch is integrated by drug sustained release and incision etc., and passive protection is changed into active treatment, fills the technical blank of existing patch in phlebitis prevention, with significant clinical practical value.Through drug sustained release technology, integrated fixing structure and modular design, realize the comprehensive promotion of phlebitis prevention, indwelling needle stable fixation and patient comfort.The film baseband is longer than traditional indwelling needle patch length, and can be conveniently torn down and replaced.

The application relates to the technical field of coal mine roadway supporting, and discloses a comprehensive active treatment method and device for coal mine roadway floor heave, which comprises the following steps: installing anchor rods and cables on the roadway roof and two sides, and excavating a compensation groove in the middle of the floor stratum; placing a pi-shaped prestressed steel beam in the groove, applying mechanical tension to the steel beam through a tensioning device, and expanding and pressing the side wall rock mass on both sides of the steel beam; then, injecting a micro-expansion cement-based grouting material into the groove; and after the grouting material is solidified to form a high-strength grouting body, releasing the tension, and transferring the prestress to the grouting body and the floor stratum. The application releases the concentrated stress in the shallow part of the floor, establishes a combined bearing structure composed of the prestressed steel beam and the grouting body in the shallow part of the floor, changes the floor rock mass into a three-way compression state, provides downward resistance bending moment, and controls the deformation of the roadway floor heave.
