The utility model discloses a multi -functional infusion soft bag, including soft bag main part, the top of soft bag main part is provided with straight pipe mouth and screw thread mouth, the surface fixed cover of straight pipe mouth is equipped with fixed cap, and the screw thread mouth is connected with screw cap, and the top of screw cap is provided with the easy -open buckle of cover jack -plug, the inside of fixed cap and screw cap all installs the rubber plug and the tablet of support below rubber plug respectively, and the straight pipe mouth and screw thread mouth are supported below the tablet in fixed cap and screw cap respectively inside. The utility model discloses through setting up straight pipe mouth for infusion and screw thread mouth for adding medicament on soft bag main part, can detach screw cap in clinical and add medicament in advance, then screw up screw cap and restore sealing, and the sealing effect is better, and the liquid medicine is not easy to be contaminated, and the storage time can be extended, when can detach easy -open buckle and add medicament from screw cap in the infusion process, avoid the influence fixed cap on normal infusion, reached according to the effect of clinical actual demand design, convenient practical.

This application discloses a self-lubricating screw lifting mechanism, belonging to the field of 3D printing equipment technology. It includes an inner screw (with a first external thread on its outer wall), a drive sleeve (with a first internal thread on its inner wall and a second external thread on its outer wall) fitted around it, a sleeve drive seat with a second internal thread on its inner wall, a transmission component for driving the drive sleeve to rotate, and a sealed cylinder with an oil storage space at the bottom. The inner screw has an axial first oil passage and a transverse second oil passage. The two pairs of threads have opposite directions of rotation. When the drive sleeve rotates, both threads and the inner screw move axially respectively, and their strokes overlap. When the inner screw descends, lubricating oil is inserted into its lower end. The oil flows out through the channels, lubricating the two pairs of threads before returning, achieving circulating lubrication. This eliminates the need for frequent manual oiling, and the mechanism has a compact structure.
