It further include third inlet tube 14, one end of the third inlet tube 14 is connected to the drip chamber 1, other end connection
In second inlet tube 13, the other end of the third inlet tube 14 is higher than the other end of the connecting tube 4, and the third
Third control switch 7, the third inlet tube 14 are provided between the other end of inlet tube 14 and the other end of the connecting tube 4
It is provided with the 4th control switch 8, the closure valve 3 is arranged between the other end and the drip chamber 1 of the connecting tube 4；
When initial, the first control switch 5, the second control switch 6, third control switch 7 and the 4th control switch 8 are closed
It closes.When the liquid of first group of Liquid dropping bottle enters the drip chamber 1 through first inlet tube 11, first control switch 5,
When squeezing drip chamber 1 makes the liquid level in drip chamber 1 to 2/3,22 floating closure valve 3 of buoyant block is closed；The third control switch 7
It opens, second control switch 6 and the 4th control switch 8 are closed；
When the liquid of first group of Liquid dropping bottle drips off, the liquid level in the drip chamber 1 declines, in the drip chamber 1
Liquid level when dropping to 1/2, buoyant block 22 is sunk, i.e., the described linkage mechanism 2 drives the closure valve 3 to open, and makes second group of drop
The liquid of liquid bottle enters to the drip chamber 1 through second inlet tube 13；
When the liquid of second group of Liquid dropping bottle enters the drip chamber 1 through second inlet tube 13, the 4th control
Switch 8 is opened, and when squeezing drip chamber 1 makes the liquid level in drip chamber to 2/3,22 floating closure valve 3 of buoyant block is closed, and described the
Three control switches 7 are closed, and the liquid of second group of Liquid dropping bottle is made to enter to the drip chamber 1 through the third inlet tube 14；
When the liquid of second group of Liquid dropping bottle drips off, when the liquid level in the drip chamber 1 drops to the 1/2 of drip chamber, drift
Floating block 22 sinks, i.e., the described linkage mechanism 2 drives the closure valve 3 to open, and second control switch 6 is opened, and described the
One control switch 5 is closed, and makes the liquid of third group Liquid dropping bottle through first inlet tube 11, the connecting tube 4 and described the
Two inlet tubes 13 enter to the drip chamber 1；
When the liquid of third group Liquid dropping bottle is through first inlet tube 11, the connecting tube 4 and second inlet tube
When the 13 entrance drip chamber 1, first control switch 5 is opened, and squeezing drip chamber 1 makes the liquid level in drip chamber 1 to 2/3
When, 22 floating closure valve 3 of buoyant block is closed；The third control switch 7 is opened, second control switch 6 and described the
Four control switches 8 are closed, and the liquid of third group Liquid dropping bottle is made to enter to the drip chamber 1 through first inlet tube 11.
By above-mentioned structure setting, in use, first group of Liquid dropping bottle is connected to the first inlet tube, second group of Liquid dropping bottle
Be connected to the second minim pipette, referring to Figures 1 and 2, at this point, the first control switch should be open, the second control switch and
4th control switch should be closed, and so that the liquid of first group of Liquid dropping bottle is entered drip chamber through the first inlet tube, and pass through
The liquid outlet of drip chamber is conveyed to patient；In above process or during connecting first group of Liquid dropping bottle, third control
Switch should be opened.In this way, the liquid level in drip chamber declines, linkage mechanism when the liquid of first group of Liquid dropping bottle drips off
It drives closure valve to open, the liquid of second group of Liquid dropping bottle is made to enter to drip chamber through the second inlet tube, and go out liquid through drip chamber
Mouth is conveyed to patient.This process is dropping liquid process from left to right.
Referring to Fig. 3 and Fig. 4, when second group of Liquid dropping bottle starts dropping liquid or during second group of Liquid dropping bottle dropping liquid, the
Four control switches are opened, and third control switch is closed, and make the liquid of second group of Liquid dropping bottle that can only enter to drop through third inlet tube
Sap cavity, and the liquid outlet through drip chamber is conveyed to patient, i.e., the liquid of second group Liquid dropping bottle cannot continue on through the second inlet tube into
Enter to drip chamber.Meanwhile after the liquid of first group of Liquid dropping bottle drips off, third group dropping liquid should be connected in the first inlet tube
Bottle.Further, when the liquid of second group of Liquid dropping bottle drips off, the liquid level in drip chamber declines, and linkage mechanism drives closure valve
It opens, and the second control switch is opened, the first control switch is closed, and makes the liquid of third group Liquid dropping bottle through the first inlet tube, even
Adapter tube and the second inlet tube enter to drip chamber, and the liquid outlet through drip chamber is conveyed to patient.This process is to turn left from the right side
Dropping liquid process.
Further, when third group Liquid dropping bottle starts dropping liquid or during third group Liquid dropping bottle dropping liquid, the first control
System switch, the second control switch and the 4th control switch are closed, and make the liquid of third group Liquid dropping bottle can only be through the first inlet tube
Drip chamber is entered to, and the liquid outlet through drip chamber is conveyed to patient, i.e. the liquid of third group Liquid dropping bottle cannot continue on through first
Inlet tube, connecting tube and the second inlet tube enter drip chamber.Repeat above-mentioned dropping liquid process from left to right；Also, in third
After the liquid of group Liquid dropping bottle drips off, also the 4th group of Liquid dropping bottle can be connected in the second inlet tube, that is, repeat above-mentioned to turn left from the right side
Dropping liquid process, the quantity of the dropping liquid according to needed for patient, so circulation dropping liquid, it is easy to use, reduce the workload of nurse, disease
People can also have more times to rest.
In the present embodiment, the linkage mechanism 2 includes connector 21 and the buoyant block being arranged in the drip chamber 1
22, one end of the connector 21 is connect with the closure valve 3, and the other end is connect with the buoyant block 22.When in drip chamber
When liquid level declines, buoyant block follows decline, to pull closure valve to open by connector.
Specifically, the closure valve 3 include the rotating valve 31 of 13 inner wall of the second inlet tube is set, and with institute
It states rotating valve 31 to be relatively fixed valve 32, one end of the connector 21 is connected to the rotating valve 31, when the drop
When liquid level in sap cavity 1 declines, the connector 21 pulls the rotating valve 31 to rotate, so that the rotating valve 31 and institute
State the separation of fixed valve 32.
Further, the inner wall of second inlet tube 13 is provided with mounting base 9, and the mounting base 9 is departing from described turn
The rotation direction of movable valve 31 is arranged, and spring 10 is provided between the rotating valve 31 and the mounting base 9.Squeeze dropping liquid
Chamber 1 rises the liquid level of drip chamber, and buoyant block follows rising, i.e., with the entrance of liquid, the liquid level in drip chamber rises, floating
Block follows rising, i.e. buoyant block no longer pulls rotating valve, and spring can pull rotating valve to reset, and realize the pass of closure valve
It closes, it is simple in sturcture, ingenious in design.Wherein, buoyant block only needs that liquid (medical fluid) can be floated on, and can pull rotating valve,
Stretch spring.
Still further, the connector 21 is drawstring, the junction of second inlet tube 13 and the drip chamber 1 is set
It is equipped with pulley 23, structure is simple, easy to use.
It is the one or more embodiments provided in conjunction with particular content as described above, does not assert specific reality of the invention
It applies and is only limited to these instructions.It is all approximate with method of the invention, structure etc., identical, or for present inventive concept under the premise of
Several technology deduction or replace are made, all should be considered as protection scope of the present invention.
