DETAILED DESCRIPTION OF THE INVENTION
This automatic stopping device for the intravenous drip comprises dripping vessel l, cap 2, connecting tube 3 and valve 4 as shown in figure l.
Dripping vessel l made of soft and transparent plastics or rubber is shaped as a cylinder provided with opening ll at the upper end for cap 2 to glue together, and short linking tube 12 at the lower end extending downward for connecting tube 3 to combine with. Connecting tube 3 has a flat top end just corresponding to the outlet at the curved bottom of dripping vessel l for 2g~
2 combining with linking -tube 30 3 Valve 4 provided with disc 41 and a long hollow 4 cone 42 extending down from disc 41 is contained in dripping vessel 1 ~or floating with disc 41 on the solu-6 tion level and blocking said outlet of dripping vessel 7 wi-th the circumferential surface of the cone 42 properly 8 touching the inside rim 31 of the top end of connecting 9 tube 3 when valve 4 goes down along with the solution level to a certain point. And the circumferential sur-11 face of the cone 42 is extremely soft and smooth, ~p 2 12 shown in figures 1 and 2 i9 provided with circumferen-13 tial groove 21 a-t the lower end fitting and being aa-14 hered with the rim of opening 11 oY dripping vessel 1, and pointed bar 22 extending up from its center which is 16 provided with crosswise round tube hole 23 near the body 17 of cap 2 and with semi-circular protrusion 24 at the 18 bottom of round tube hole 230 Inslde round tube hole 23 19 is set ring 25 which can move rightward and leftwaxd therein and in round tube hole 23 is fixed hollow 21 stopper 26.
22 Besides, pointed bar 22 is also provided with leng-23 thwise solution passage 27 from the upper end to the 24 lowex end for the solution in the solution bottle to flow down in dripping vessel 1 and with air passage 28 26 f'rom the. upper end to round tube hole 23 for the atmos-27 pheric air to flow in the solution bot-tle.
28 . Setting ring 25 inside round tube hole 23 aims to 2 prevent the solu-tion from escaping therefrom. Dripping 3 vessel 1 has at first to be pressed with f`ingers forcing 4 the air inside vessel 1 to flow through solution passage 27 into the ~olution bottle and through connecting tube 6 3 when this device is inserted in the solution bottle 7 for appl~ing intravenous drip. As the air has entered 8 the solution bottle, ring 25 could be forced to move 9 rightward to block the hole of hollow stopper 26 so the solution could not flow out therefrom, When the pressure 11 in dripping vessel 1 disappears, the solution gradually 12 begins to flow down from the bottle into dripping vessel 13 1 and -then ring 25 moveg leftward and is stopped by pro-14 trusion 24 so as not to block air passage 28 letting the atmospheric air to flow through hollow stopper 26 and 16 air pas~age 28 into solution bot-tle, 17 Connecting tube 3 is a common soft plastic tube to 18 connect with dripping vessel at -the upper end and an in-19 jection needle at the lower end and its out~ide diameter just conforms the inside diameter of linking tube 12 of 21 dripping vessel 1, both of them being adhered togetherO
22 ~esides, top rim 31 of said tube 3 has a smooth flat 23 sur~ace for the circumferential surface of cone 42 o~
24 valve 4 to touch wi-th so that the passage of the ~olu-tion can be blocked.
26 Next, valve 4 made of plastics is provided with a 27 round flat body~ hollow cone 42 extending downward from 28 the body and flat disc 41 glued on the body making up a 6~
2 hollow space inside cone 42 so as to float in the solu-tion O
4 ~igure ~ shows this device in practical use; pointed bar 22 i9 inserted in the solution bottle 5 put upside 6 down and the solution drips down slowly through solution 7 passage 27 into dripping vessel 1~ '~he solution continues 8 to drip down into dripping vesse] ~aking valve 4 to float 9 and rise up along with the solu-tion level until the solu-tion level reaches to such a hight that the solution ca~
11 be let out of connecting tube 3.
12 When all the solu-tion in -the solution bottle 5 has 13 flowed out and the solution level in dripping vessel 1 14 is gradually going down as shown in figure 4, valve 4 is also falling down to make the circumferential suYface of 16 cone 42 finally touch around the top rim 31 of connecting 17 tube 3 to block the passage of the solution so that air 18 can never be injected into a human body.
19 In case the intravenous drip still has to continued after one bottle has been used up, then dripping vessel 1 21 should be pinched with fingers at the place below valve 4 22 making the solution level and valve 4 rise up lest cone 23 42 of valve 4 should block connecting tube 3. ~herefore, 24 the solution can continuously be injected in the human 2.5 body and a new solution bottle can be fixed to take the 26 place of an old bottle.
27 In short, this device has a simple structure and a 28 cheaper cost than the conventional one. Its f-lnction in 6~;31 2 hampering the solution is quite accurate, and above all, 3 resumption of injection is so simple as to be accom-4 plished by pinching the dripping vessel with the thumb and the index finger. Surely this dev:ice is more handly 6~ than the conventional one provided with an air tube in 7 the solution bottle which is not need~d in this device.

8 Once a kind of automatic stopping devlce has been 9 made, provided in the dripping vessel which can float on the ~olution level and fall down with it ~lhen the solu-11 tion is going to run out. ~ut the float is round and 12 rather hard to maXe. Especially its material should have 13 : a proper weight and a buoyancy such as plastics.
