The invention provides an anti-displacement tube type ductus venosus which sequentially comprises a catheter, a connecting base and an extension pipe, and the catheter, the connecting base and the extension pipe are connected and communicated with one another. The portion, in the position of the opening of the connection base, of the catheter is of a needle base structure, and a puncture needle is inserted into the catheter through the needle base structure. The extension pipe is sequentially communicated with the connecting base and the catheter through the side wall of the connecting base. Catheter fixing wings and a float are sequentially arranged on the connection position of the connection base and the catheter, the faces, attached to the human skin, of the catheter fixing wings and the face, attached to the human skin, of the float are respectively provided with a sticking and fixing structure, and each sticking and fixing structure sequentially comprises a sticking layer and a protection layer from inside to outside. The anti-displacement tube type ductus venosus is convenient to use, easy to operate, good in fixing effect, and capable of effectively preventing a patient from great pains which are produced when the exposed portion of an anti-displacement tube type ductus venosus body is sewn on and fixed to the skin through the puncture needle and threads in a percutaneous mode, the anti-displacement tube type ductus venosus can be effectively prevented from being blocked, when negative pressure exists in the anti-displacement tube type ductus venosus, an opening can be effectively formed, medical staff can conveniently draw return blood so as to confirm whether the ductus venosus is placed in the vein or not and can conveniently draw back hydrops so as to confirm whether the hydrops exists in the body cavity or not, life health of the patient can be effectively ensured, and dangers are prevented from occurring.

The invention discloses a streetlamp. Streetlamps are evenly arranged on guardrails on two sides of a street and used for illumination in foggy road sections. The streetlamp comprises a lamp box, high-color-temperature LED beads, a transparent window and a lampshade, wherein the lamp box is fixedly arranged on a guardrail; the high-color-temperature LED beads are arranged inside the lamp box; the transparent window is arranged outside the lamp box, and the periphery of the transparent window is detachably connected with the lamp box; and the lampshade is arranged at the top of the lamp box. The streetlamp provided by the invention adopts the high-color-temperature LED beads, the visual recognizing capacity of drivers or pedestrians can be improved, and drivers can safely drive on foggy days, see distant obstacles clearly and avoid the obstacles in time, so that traffic accidents are avoided, and the life and health of drivers are effectively ensured.

The invention discloses a test paper binding device and method. The test paper binding device comprises a binding platform placed on a table. Binding frames which are symmetrical in the left-right direction are fixedly arranged on the upper end face of the binding platform. Inlets which are open outwards are fixedly formed in the end faces, away from each other, of the binding frames. Driving cavities are formed in the end walls, close to each other, of the inlets in a communicating mode. Pressing cavities which are symmetrical in the vertical direction are formed in the end walls, away from the inlets, of the driving cavities in a communicating mode. The end walls, away from the inlets, of the pressing cavities communicate with the external space. Connecting cavities are formed in the pressing cavities in a communicating mode. The test paper binding device is simple in structure and convenient and fast to use; compared with a stapler, time is greatly saved; the test paper binding device punches holes in the edges of test paper, so that potential safety hazards caused by the stapler are avoided, the life health of users is ensured, the work efficiency is effectively improved, and the safety of the test paper binding device is improved.
