Figure 2 As shown, when the device is used, after the lifting pile 23 moves inside the fixed pile 21, the first tightening bolt 22 can be rotated so that one end of the first tightening bolt 22 abuts against the outer surface of one side of the lifting pile 23, thereby fixing the position of the lifting pile 23;
[0024] A limit plate is provided on the outer surface of the lower end of the lifting pile 23, and the length and width of the outer side of the limit plate are the same as the length and width of the inner side of the fixed pile 21. Figure 2 As shown, when the device is in use, the lifting pile 23 can be moved inside the fixed pile 21, so as to facilitate the adjustment of the device's medication height and make the lifting pile 23 more stable when moving;
[0025] A drug administration structure 3 is provided on the upper end of the adjustment structure 2, and the drug administration structure 3 is used to administer drugs to the affected part of the parturient;
[0026] The dosing structure 3 includes a dosing cylinder 31, and a plurality of dosing holes are provided on the outer surface of the dosing cylinder 31, a piston rod 32 is inserted into the interior of the dosing cylinder 31, and a control baffle 33 is sleeved on the outer surface of the piston rod 32, and the internal threads of the upper end surfaces of both sides of the control baffle 33 are connected with second tightening bolts 34, one end of the piston rod 32 is fixedly connected with a piston push plate 35, a connecting plate 36 is fixedly connected to the outer surfaces of both sides of one end of the dosing cylinder 31, and a fixed plate 37 is fixedly connected to the inner wall surfaces of both sides of the connecting plate 36, and movable grooves 38 are provided on the outer surfaces of both sides of the connecting plate 36, movable slide grooves are provided inside the surfaces of both sides of the control baffle 33 and the piston push plate 35, and the width and height dimensions of the movable slide grooves are the same as the width and height dimensions of the fixed plate 37, and blocks are provided on the outer surfaces of the upper and lower ends of both ends of the fixed plate 37. Figure 3 As shown, when the device is in use, the design allows the control baffle 33 and the piston push plate 35 to move on the outer surface of the fixed plate 37, and makes the control baffle 33 and the piston push plate 35 more stable when moving, and the moving distance of the control baffle 33 and the piston push plate 35 is limited by the design of the stopper, so as to avoid the control baffle 33 and the piston push plate 35 from being separated from the outer surface of the fixed plate 37;
[0027] The upper end surfaces of both sides of the connecting plate 36 are provided with scale lines, the outer surfaces of both sides of the upper end of the control baffle 33 are provided with triangular indicator blocks, and the lower end of the second tightening bolt 34 is against the upper end surface of the fixing plate 37. Figure 3 As shown, when the device is in use, the control baffle 33 is moved, and the overlapping position of the triangular indicator block on the outer surface of the upper end of the control baffle 33 and the scale line set on the upper end surface of the connecting plate 36 is observed. When the control baffle 33 moves to a suitable position, the position of the control baffle 33 can be fixed by rotating the second tightening bolt 34, and thereby the pushing distance between the piston push plate 35 and the piston rod 32 is limited, so as to achieve the purpose of controlling the dosage of the device;
[0028] The rubber gasket 25 is made of rubber material, and the rubber gasket 25 is slidably connected to the inside of the moving groove 38, and the outer diameter of the rubber gasket 25 is the same as the height of the inside of the moving groove 38. Figure 2 and Figure 3 As shown, when the device is in use, the elasticity and toughness of the rubber material itself can increase the friction between the rubber gasket 25 and the inner wall surface of the movable groove 38. This design allows the connecting plate 36 to move on the outer surface of the rubber gasket 25 through the movable groove 38, and allows the connecting plate 36 to change synchronously with the position of the rubber gasket 25 through the movable groove 38, and the position of the connecting plate 36 can be fixed through the rubber gasket 25 by rotating the threaded rod 24.
[0029] Working principle: When the equipment is in use, first place the supporting base plate 1 at a suitable position, then pull the piston push plate 35 to make the piston rod 32 disengage from the interior of the dosing cylinder 31, and inject the medicine into the interior of the dosing cylinder 31, then push the piston push plate 35 in the opposite direction to make the piston rod 32 reinsert into the interior of the dosing cylinder 31, observe the scale lines set on the upper end surfaces of both sides of the connecting plate 36, move the control baffle 33 on the outer surface of the fixed plate 37, and observe the overlapping position of the triangular indicator blocks set on the outer surfaces of both sides of the upper end of the control baffle 33 and the scale lines, when the control baffle 33 moves to a suitable position, rotate the second tightening bolt 34 so that the lower end of the second tightening bolt 34 abuts against the upper end surface of the fixed plate 37 to fix the position of the control baffle 33, and then rotate the four groups of threaded rods 24 so that the outer surfaces of the four groups of rubber gaskets 25 are inserted into the interior of the movable groove 38 but do not fit with the inner surface of the movable groove 38;
[0030] Next, according to the actual situation of the affected part of the parturient, the two groups of lifting piles 23 are respectively pulled out upward from the inside of the two groups of fixed piles 21, and the height difference between the two groups of lifting piles 23 can be adjusted according to the actual required angle. After the adjustment of the lifting piles 23 is completed, the first tightening bolt 22 is rotated so that one end of the first tightening bolt 22 abuts against the outer surface of one side of the lifting pile 23, thereby fixing the position of the lifting pile 23. At the same time, due to the adjustment of the height of the two groups of lifting piles 23, the four groups of rubber gaskets 25 are moved synchronously, so that the connecting plate 36 rotates along with the movement of the rubber gasket 25 through the moving groove 38, and then the connecting plate 36 moves on the outer surface of the rubber gasket 25 through the moving groove 38, and the outer surface of the drug delivery barrel 31 is inserted into the inside of the affected part of the parturient at the same time. At this time, the four groups of threaded rods 24 are rotated so that the outer surfaces of the four groups of rubber gaskets 25 abut against the inner surface of the moving groove 38, thereby fixing the position of the connecting plate 36 through the rubber gasket 25, thereby fixing the height and angle of drug delivery of the drug delivery structure 3 through the adjustment structure 2;
[0031] When administering the medicine, the piston push plate 35 is pushed to drive the piston rod 32 to move inside the dosing barrel 31, and the medicine inside the dosing barrel 31 is evenly smeared on the inside of the affected part of the parturient through multiple groups of dosing holes. When the piston push plate 35 is pushed so that one side surface of the piston push plate 35 is in contact with one side surface of the control baffle 33, the piston push plate 35 can no longer be pushed, thereby controlling the amount of medicine administered by the device through the control baffle 33, and then the above operation is reversed to withdraw the dosing barrel 31 from the inside of the affected part of the parturient. The above is the entire working principle of the present invention.
