To realize the utility model aim, the technical solution of use are as follows: one kind stops liquid type infusion apparatus, including successively through hose Puncture outfit, infusion bag, drop pot, flow regulator and the intravenous needle of connection；It is characterized in that, the drop pot includes cavity, lower end The intracorporal only fluid column of the cylinder and cylinder of opening；The inner wall of cylinder lower end and the outer wall thread of cavity upper end are cooperatively connected；Only fluid column Outer wall include the inverted cone shape outer wall of upper section and the cylindrical outer wall of lower section, only the bottom end of fluid column has counterweight protrusion；Cavity Upper wall offers only fluid apertures compatible with only fluid column outer wall；The outer wall of cylinder is multiple perpendicular with what is be circumferentially evenly spaced on Item, the lower end of vertical bar extend to that cavity is outer and at L-shaped, and each L-shaped opening in vertical bar lower end is towards cavity；The outer wall of cavity has There is a land, and land is corresponding in all L-shaped openings in vertical bar lower end；Outside hose between the drop pot and flow regulator It is vertically fixed with the plug pipe of lower ending opening on wall, fills in and is fixed with rubber plug part in the lower ending opening of pipe.

Further, the vertical bar is structure as a whole with cylinder.

Further, the outer wall side of the plug pipe is fixed with and snap ring, and the center line of snap ring is parallel with tube hub line is filled in, Snap ring is fastened on the hose outer wall between drop pot and flow regulator.

Further, the hose outer wall of the corresponding snap ring lower end is equipped with supporting table.

Further, the supporting table is structure as a whole with hose.

The utility model has the beneficial effects that improving by the structure of drop pot, it is divided into cylinder and cavity, and pass through the two It is threadedly engaged and the connection of vertical bar and land realization the two is installed, and facilitate adjustment, only the position of fluid column facilitates adjustment to entangle Just, it is scrapped due to stopping fluid column position and deviation occur caused by one-pass molding before avoiding, the L shape of vertical bar lower end is to land with pole Extreme position limitation and support, securely and reliably, and intravenous needle can be also inserted into before infusion in the rubber plug part of the lower end Xiang Saiguan, side Just it places, avoid falling.
