The utility model relates to a guiding catheter which comprises a catheter base. The injection tube is connected with the tube seat, and the tube diameter of one end, far away from the tube seat, of the injection tube is adjustable; the metal filament is arranged in the injection tube along the axial direction of the injection tube, and one end of the metal filament is connected with the tube seat; the extension tube is connected with the injection tube, and the injection tube penetrates into a tube body of the extension tube; the anchoring part is arranged on the extension pipe and can be used for anchoring the extension pipe; when the anchoring part is in a contracted state, the medical instrument can penetrate through the interior of the extension pipe through the anchoring part. When the anchoring part is in the full state, the anchoring part expands in the radial direction of the extension pipe and abuts against the anchoring position so as to anchor the extension pipe. According to the guiding catheter provided by the invention, the guiding catheter can be directly anchored in the guiding catheter, so that the guiding catheter is prevented from displacing.

The utility model relates to the technical field of medical storage boxes, in particular to an edge tool box which comprises a box body, a middle partition plate, a sponge cushion layer, a top column, a buffering mechanism, a box cover, a first cover plate, a second cover plate and a third cover plate. The box cover is provided with the three feeding openings, so that the sharp instruments can be fed into the box by selecting the proper feeding openings according to the specifications of the sharp instruments during use, the sharp instruments can be fed into the box more smoothly and safely, and the sponge cushion layer arranged at the bottom of the box body can buffer the feeding of the container and absorb residual liquid flowing out of the container. And through the buffering mechanism arranged in the box body, when the sharp instruments are put in a driving mode, the sharp instruments can be buffered under the action of the buffering mechanism, so that the sharp instruments cannot rebound and splash out, the sharp instruments cannot penetrate through the sharp instrument box even if the sharp instruments penetrate through the porous sponge layer, and normal use of the sharp instrument box is guaranteed.

The utility model discloses a device of cooperation children anaesthetized under magnetic resonance examination relates to medical auxiliary technical field. Including split type mattress, this split type mattress is divided into the headrest area of supporting head portion and the main body support area of bearing body, and all are by the upper pad layer and lower pad layer of interconnection composition, head adjustment subassembly is set up above headrest area, is used for adjusting the head of patient is the head -up and holds the state of the chin. The utility model can promote the safety, accuracy and comfort of children nuclear magnetic resonance scanning examination.

This invention provides a method for fabricating precast box girder tracks for highways, belonging to the field of track fabrication technology. The method includes the following steps: S1: Concrete preparation, where screened cement, crushed stone, and sand are mixed according to a concrete mix design to obtain castable concrete; S2: Steel frame preparation, where steel bars and prestressed steel strands are combined after ensuring the materials are qualified to obtain a precast steel frame; S3: Concrete pouring, where the concrete pouring equipment includes a steel frame conveying mechanism for positioning and conveying the steel frame, a pouring mold for placing the steel frame for positioning and pouring, a demolding mechanism for quickly demolding the formed precast beam, and a moving pouring mechanism for uniform pouring; S4: Demolding and curing, where the precast beam is cured using curing equipment, ensuring that after the concrete pouring is completed and the slurry has settled, it is covered and watered for curing as soon as possible; S5: Finishing work. This invention facilitates rapid demolding of precast beams, achieving efficient demolding.

The application relates to the field of construction auxiliary equipment, in particular to auxiliary equipment for repairing ancient buildings based on color drawing construction, which comprises two left-right symmetrical connecting frames and moving assemblies and the like; the connecting frame is composed of two up-down symmetrical connecting blocks and a connecting plate; each connecting block is provided with a moving assembly. The application places two connecting frames at the two ends of a house beam, fixes the two ends of a spectrum on the two connecting frames, and simultaneously makes the spectrum completely cover the front side of the house beam, so that the spectrum is fixed, the manual operation of multiple people is omitted, the work efficiency is improved, the two connecting frames are independently separated structures, the interval can be flexibly adjusted according to the length of the house beam and the spectrum, and the applicability is high; in addition, the two connecting frames with consistent sizes ensure the positioning accuracy of the spectrum, effectively avoid the spectrum inclination or misplacement caused by improper cooperation during manual fixing, prevent the powder printing from being inclined during subsequent spectrum shooting, and ensure the overall regularity of the color drawing pattern.
