Concrete meaning of the language in the utility model.
A kind of structure chart of infusion pump automatic flow control device of Fig. 1 the utility model, as illustrated, the utility model is disclosed
A kind of infusion pump automatic flow control device, it includes entrance threeway 1, outlet threeway 5, switch 10, constant current speed flowtube 3.2 and hand
Dynamic infusion channel, anther sac inlet tube 9 that the manual infusion line includes being sequentially connected with, anther sac 8, anther sac outlet 7 and manually
Infusion flowtube 3.1, wherein, a mouth of pipe of the entrance threeway 1 is used to be connected with outside liquid supply equipment, a mouth of pipe connection
One end of the constant current speed flowtube 3.2 a, mouth of pipe connects one end of the anther sac inlet tube 7, the one of the outlet threeway 5
The individual mouth of pipe is used to be connected with outside liquid equipment, and a mouth of pipe connects the other end of the constant current speed flowtube 3.2, a mouth of pipe
Connect one end of the manual infusion flowtube 3.1.The switch 10 is one and is exported by holding anther sac inlet tube 9 or anther sac tightly
Pipe 7 controls the break-make of manual infusion channel manually.
The present embodiment also includes for encapsulating the housing 2 of this infusion pump automatic flow control device, the entrance threeway 1, goes out
Mouth threeway 5, switch 10, constant current speed flowtube 3.2 and manual infusion channel are each attached in housing 2, and the entrance threeway 1 is used
It is placed in outside the housing 2 in the mouth of pipe of the outside liquid supply equipment of connection；The outlet threeway 5 is used for what is be connected with outside liquid equipment
The mouth of pipe is placed in outside the housing 2.Also include elbow 6 in the structure of manual infusion channel, the elbow 6 is arranged on anther sac outlet
Between pipe 7 and manually infusion flowtube 3.1, the elbow 6 is used to guide liquid to turn to, and the angle of elbow 6 is preferably 90 °, both
The space of housing 2 can be saved, guiding liquid can be played a part of again and is turned to.The anther sac 8 is used to store liquid, because from entering
Mouth threeway 1 is flowed into the medicinal liquid flow of anther sac 8 more than the medicinal liquid flow for flowing into outlet threeway 5 through flowtube from anther sac 8.Anther sac enters
The internal diameter of mouth pipe 9 and anther sac outlet 7 is much larger than the interior of flowtube 3 less than entrance threeway 1 and the internal diameter of outlet threeway 5
Footpath, because anther sac inlet tube 9 and anther sac outlet 7 do not play throttling action, only serves conveying effect.Anther sac 8 is circular or side
The container of shape, when anther sac 8 has been expired, entrance threeway 1 then no longer conveys liquid toward anther sac inlet tube 9.
The operation principle of the present embodiment is as follows：Under pressure, entrance threeway 1 is connected by constant current speed flowtube 3.2
Outlet threeway 5 is connected to, when switch is not pressed, manual infusion channel is closed, and liquid can only be by determining flow rate
Pipe 3.2, this state is the liquid supply of constant flow rate.When switch is pressed, manual infusion channel conducting, a part of liquid leads to
Constant current speed flowtube 3.2 is crossed, another part liquid manually infusion channel is finally converged, now in outlet in outlet threeway 5
The liquid flow velocity of threeway 5 increases the effect of medicinal liquid flow to reach more than the liquid flow velocity when switch is not pressed.
The utility model increased a manual infusion channel on the basis of traditional constant current speed flowtube, both can be with
Meet the demand of constant current speed, can be needed to increase dose at any time according to clinic again, it is easy to use, can very fast reduction of patient pain
Sense, while reducing the labour intensity of medical personnel.
Wherein, also including adapter 4, the constant current speed flowtube 3.2 is connected by adapter 4 with the outlet threeway 5.
Wherein, the internal diameter of the manual infusion flowtube 3.1 and constant current speed flowtube 3.2 is between 0.04-0.06mm.Hand
Dynamic infusion flowtube 3.1 and constant current speed flowtube 3.2 play a part of throttling, using its special construction, can according to its length,
Change resistance of the liquid in flowtube, so as to control the flow velocity of liquid, specifically, flowtube is more long, the flow velocity of liquid is smaller.
Wherein, the internal diameter of the entrance threeway 1 and outlet threeway 5 is between 1mm-2mm.The entrance threeway 1 and outlet
The internal diameter of threeway 5 can meet enough medicines much larger than infusion flowtube 3.1 manually and the internal diameter of constant current speed flowtube 3.2
Liquid inlet and outlet, does not result in infusion flowtube 3.1 manually and the constant current speed Chinese medicine liquid of flowtube 3.2 is less, causes it to act on
The consequence of failure.
Wherein, the adapter 4 is connected with the mouth of pipe at the right angle end of the outlet threeway 5.
Wherein, the constant current speed flowtube 3.2 is connected with the mouth of pipe at the straight-through end of entrance threeway 1.Liquid is from the entrance
The straight-through end of threeway 1 is connected to outlet threeway 5 right angle end by constant current speed flowtube 3.2 and adapter 4.
The utility model increased a manual infusion channel on the basis of traditional constant current speed flowtube, both can be with
Meet the demand of constant current speed, can be needed to increase dose at any time according to clinic again, it is easy to use, can very fast reduction of patient pain
Sense, while reducing the labour intensity of medical personnel.
Presently preferred embodiments of the present invention is the foregoing is only, is not intended to limit the invention, it is all in essence of the invention
Within god and principle, any modification, equivalent substitution and improvements made etc. should be included within the scope of the present invention.
