As everyone knows, existing transfusion device (is called again by syringe needle, tube for transfusion, actuator, dropper
luxuriant Fei Shi dropperor Murphy's dropper), infusion bottle and drip stand form.There is certain shortcoming in existing transfusion device: such as being totally lost when one bottle of liquid, fails timely fluid infusion or while pulling out pin, air can blow back into tube for transfusion by syringe needle by syringe needle intravasation or blood and produce blood back; The two is all unhealthful.Therefore, patient tends to ceaselessly stare at transfusion drip tube, sees that liquid has dripped off soon, and nurse call at once, by nurse's fluid infusion or pull out pin hastily.Due to patient, nurse high-pressure all, therefore often there is offending thing to occur.Therefore only have the performance of thorough change transfusion device, could go and fundamentally deal with problems.
Utility model content
The purpose of this utility model is the intravenous transfusion device that a kind of venous transfusion dropper is provided and applies this dropper at this.Effectively overcome the problem that above-mentioned existing mode of operation exists, do not need to report to the police; Air can intravasation, does not occur the infusion set of the high safety of blood back yet.
This utility model is achieved in that a kind of venous transfusion dropper of structure, it is characterized in that: comprise dropper A, dropper B, two tube side-by-sides are in series; Adopt tube for transfusion to connect with the upper end of dropper B the lower end of dropper A.
According to venous transfusion dropper described in the utility model, it is characterized in that: between described dropper A, dropper B, movable clip is set, employing activity clip fixes with each other it both clampings; Prevent that dropper A, dropper B are offset mutually, be conducive to the carrying out of transfusion.
According to venous transfusion dropper described in the utility model, it is characterized in that: also comprise shell; Make its dropper A and dropper B be positioned at shell, make it form an integral body; Side-by-side and keep the dropper of certain height difference to wire up by two with shell, become as a whole and make it attractive in appearance and there is object easy to use.
According to venous transfusion dropper described in the utility model, it is characterized in that: described dropper A, dropper B are all with gas outlet.
According to venous transfusion dropper described in the utility model, it is characterized in that:
The long 10-14cm of described dropper A;
The long 8-12cm of described dropper B;
The upper end of described dropper A exceeds the upper end 2-4cm of dropper B.
A kind of intravenous transfusion device, comprise syringe needle, tube for transfusion, actuator, venous transfusion dropper, infusion bottle and drip stand, syringe needle adopts tube for transfusion to connect with actuator, and actuator connects with venous transfusion dropper, venous transfusion dropper adopts tube for transfusion to connect with infusion bottle, and infusion bottle hangs on drip stand; It is characterized in that: venous transfusion dropper comprises dropper A, dropper B, and two tube side-by-sides are in series; Adopt tube for transfusion to connect with the upper end of dropper B the lower end of dropper A.
According to intravenous transfusion device described in the utility model, it is characterized in that:
Between described dropper A, dropper B, movable clip is set, employing activity clip adds both to hold to be fixed.
Intravenous transfusion device according to claim 1, is characterized in that: also comprise shell; Make its dropper A and dropper B be positioned at shell, make it form an integral body.
According to intravenous transfusion device described in the utility model, it is characterized in that: described dropper A, dropper B are all with gas outlet.
According to intravenous transfusion device described in the utility model, it is characterized in that:
The long 10-14cm of described dropper A;
The long 8-12cm of described dropper B;
The upper end of described dropper A exceeds the upper end 2-4cm of dropper B.
Venous transfusion dropper described in the utility model comprises dropper A and dropper B, and wherein dropper A is about 12cm, and dropper B is about 9cm; The caliber of two pipes and existing common dropper are almost large, with tube for transfusion, two pipes are together in series; And make the upper end of dropper A higher than the about 3cm in upper end of dropper B.
Its operation principle is as follows: while having medicinal liquid in infusion bottle, liquid constantly enters dropper A; When dropper A liquid level exceeds the top (being h1) of dropper B, liquid splashes into dropper B, and through syringe needle input human body, has started normal infusion the same as existing transfusion device.At this moment can observe from the upper end of dropper A and dropper B the speed of transfusion, and control transfusion speed by actuator.When the liquid in infusion bottle is totally lost, in dropper A, liquid no longer increases, also with regard to no longer because action of gravity enters dropper B, and residual liquid (for example fluid column h2-h3) gravitate in dropper B still continues to flow to blood vessel.Along with the continuous decline of liquid level h2 in dropper B, so formed a vacuum space in the upper end of dropper B; The negative pressure of its vacuum works to two aspects, and the one, the draws fluid in dropper A is come, the 2nd, the residual liquid that holds dropper B lower end does not allow it spill out; In dropper B, greatly to a certain extent, with the gravitational equilibrium of its lower end residual liquid, at this moment residual liquid no longer flows to syringe needle the negative pressure of vacuum, and whole transfusion is ended automatically.This automatic termination, after termination, dropper A and dropper B lower end still have residual liquid to exist, and air cannot pass through, so can intravasation.Because the residual liquid in dropper B after automatically ending still has certain pressure to vein blood vessel, its pressure and venous pressure balance, so there will not be blood back again.
The utility model has the advantage of: the intravenous transfusion device that this utility model provides a kind of venous transfusion dropper and applies this dropper at this; Have the following advantages:
(1) venous transfusion dropper, comprises dropper A, dropper B, and two tube side-by-sides are in series; Adopt tube for transfusion to connect with the upper end of dropper B the lower end of dropper A.When in venous transfusion bottle, liquid has flowed, transfusion is just ended automatically, can effectively overcome existing transfusion device and enter air, the large shortcoming of blood back two.Eliminate patient's anxiety, alleviate nurse's work.
(2) venous transfusion dropper described in the utility model, can arrange movable clip between described dropper A, dropper B, and employing activity clip fixes with each other it both clampings; Prevent that dropper A, dropper B are offset mutually, be conducive to the carrying out of transfusion.
(3) venous transfusion dropper described in the utility model, can also comprise shell; Make its dropper A and dropper B be positioned at shell, make it form an integral body; Side-by-side and keep the dropper of certain height difference to wire up by two with shell, become as a whole and make it attractive in appearance and there is object easy to use.
